BACKGROUND
Field of the Invention
[0001] The present invention generally relates to tables including at least a portion constructed
from plastic and may include molded plastic components.
Description of Related Art
[0002] Many different types of tables are well known and used for a variety of different
purposes. For example, conventional tables may include legs that are pivotally attached
to a table top and the legs may be movable between a use position in which the legs
extend outwardly from the table top and a storage position in which the legs are folded
against the table top. Conventional tables with relatively large table tops and folding
legs are often referred to as "banquet tables" and these tables are frequently used
in assembly halls, banquet halls, convention centers, hotels, schools, churches and
other locations where large groups of people meet. These types of tables can often
be positioned in an assortment of different configurations and used in a variety of
settings. When the banquet tables are no longer needed, the table legs can be moved
into the storage position and the tables may be more easily moved or stored.
[0003] Because most banquet tables have a length between six and ten feet and a width between
three and four feet, the required storage area for such tables is quite large even
with the legs in the collapsed position. This large storage area may be problematic
for businesses or facilities such as hotels, schools and churches because a considerable
number of these tables may have to be stored.
[0004] Conventional tables often include table tops constructed from materials such as wood,
particle board or metal. Table tops constructed from wood, particle board or metal,
however, are often relatively heavy and this may make the table awkward or difficult
to move. Table tops constructed from wood or metal are also relatively expensive and
these types of table tops must generally be treated or finished before use. For example,
table tops constructed from wood must generally be sanded and painted, and metal table
tops must be formed into the desired shape and painted. In addition, because these
wooden and metal table tops are relatively heavy, the cost of shipping and transportation
of the tables may be increased. The weight of the table top may make the tables more
difficult to move and store.
[0005] In order to decrease the weight of conventional tables, table tops may be constructed
from relatively light-weight materials such as plastic. Disadvantageously, table tops
constructed from light-weight materials may require large reinforcing members or other
structural parts such as braces, brackets, support members and the like to strengthen
the table top. While these additional parts may increase the strength of the table
top, the added parts may also increase the weight of the table. These additional parts
may result in increased manufacturing costs and require additional time to assemble
the table. In addition, extra fasteners may be required to assemble and connect these
parts to the table, which may require extra time and labor during the manufacturing
process. The additional parts and fasteners may further increase the cost of the table
and make the table more difficult to manufacture. Moreover, these additional parts
and fasteners may have sharp edges that can injure a user's legs or arms.
[0006] Conventional tables may include a frame that is connected to the table top. The frame
may include a pair of side rails connected to sides of the table top using fasteners.
Multiple fasteners may be required to securely connect the frame to the table top
and transmit forces applied to the table top to the frame. Undesirably, when a relatively
large load or force is applied to some known tables, the frame may bend, deform and/or
detach from the table top. In addition, the fasteners used to connect the frame to
the table top may detach or separate from the table top. The fasteners may even damage
and tear through the table top if the load or force exceeds a certain amount. Further,
the frames or fasteners of some known tables may collapse in some circumstances.
[0007] The table top of some known tables may undesirably bend or deform if a relatively
large load or force is applied to a portion of the table top. For instance, if the
load or force is applied to an outer portion of a conventional table top, that portion
of the table top may undesirably move or bend. In particular, that portion of the
table top may deflect downward when the load or force is applied to the upper surface
of the table top.
[0008] The large size of conventional banquet tables may require a large amount of storage
space for manufacturers, retailers and consumers. The large amount of storage space
may be particularly problematic for manufacturers, retailers and consumers that have
a need to store, transport and/or display large numbers of tables.
[0009] US 2009/114131 discloses a structure constructed from plastic which may include one or more reinforcing
portions that are sized and configured to prevent damage to the structure. The structure
may be for example a table top constructed from blow-molded plastic. The corners of
the table top may include an interior portion and an exterior portion, and reinforcement
portions sized and configured to help prevent damage to the corners of the table top.
In addition, one or more depressions may be at least partially disposed within the
reinforcement portions.
BRIEF SUMMARY
[0010] A need therefore exists for a table that eliminates or diminishes the above described
disadvantages and problems.
[0011] According to the invention there is provided a table top sized and configured to
nest with an adjacent identical table to reduce a height of a plurality of stacked
tables in a nested configuration, the table top being constructed from molded plastic,
the table top comprises:
an upper surface;
a lip comprising an outer wall and an inner sidewall;
a receiving portion at least partially disposed in the upper surface and the outer
wall of the lip, the receiving portion being a groove or a channel with a height and
width, the receiving portion being disposed about an outer perimeter of the table
top, the receiving portion receiving an engaging portion of an adjacent table when
the tables are disposed in a nested configuration;
a lower portion; and
a plurality of strengthening members disposed in the lower portion of the table top
that support the receiving portion, each strengthening member of the plurality of
strengthening members including an inner portion that supports an inner portion of
the receiving portion;
the upper surface, the receiving portion, the lower portion, the lip and the plurality
of strengthening members being integrally formed during a molding process as part
of a unitary, one-piece construction;
wherein the strengthening members extend inwardly or horizontally relative to the
lower portion of the table top;
wherein at least a portion of the strengthening members are disposed in the inner
sidewall of the lip and have a generally curved or arc-shaped configuration;
wherein the inner portion of the strengthening members contacts the inner portion
of the receiving portion; and
wherein an inner surface of the strengthening members is spaced apart from the outer
wall of the lip.
[0012] The table may include a table top and one or more legs sized and configured to support
the table top above a surface such as the floor or ground. The table may also include
a frame and legs connected to the frame. The legs may be movable relative to the table
top between a collapsed or storage position and an extended or use position. In particular,
the legs may be pivoted between a collapsed position in which the legs are disposed
at least proximate a lower surface of the table top and an extended position in which
the legs extend outwardly from the table top. If desired, the legs may at least partially
contact or abut the lower surface of the table top when the legs are in the collapsed
position. In addition, the lower surface of the table top may include one or more
recesses sized and configured to receive at least a portion of the legs when the legs
are in the collapsed position. Advantageously, this may decrease the amount of space
required to store and/or transport the table.
[0013] The table may be relatively lightweight, which may allow the table to be more easily
transported and moved. For example, the table may include a lightweight table top
and that may reduce the overall weight of the table. The table may also be constructed
from a limited number of parts or components, which may allow the weight of the table
to be reduced. Further, a limited number of fasteners may be required to assemble
the table, which may also reduce the weight of the table. The limited number of fasteners
may also allow the table to be quickly and easily assembled.
[0014] The table top may be constructed from molded plastic using blow-molding, injection
molding, rotary molding or other suitable molding processes. The molded plastic table
top may provide a relatively rigid, high-strength structure capable of withstanding
repeated use and wear. The molded plastic table top may also be relatively quickly,
easily and efficiently manufactured. In addition, the molded plastic table top may
be readily molded into a desired size and shape, such as a utility table, card table,
personal table and the like. The molded plastic table top may be relatively lightweight
because, for instance, it may include a hollow interior portion formed during the
molding process. The molded plastic table top may further include two opposing walls,
which may be spaced apart by a generally constant and/or predetermined distance, and
that may help increase the strength and rigidity of the table top. Additionally, the
molded plastic table top may be generally weather resistant and temperature insensitive.
Further, the molded plastic table top may not corrode, rust or otherwise deteriorate
over an extended period of time, which may help create a long-lasting table.
[0015] The table top may be constructed from molded plastic and one or more features may
be integrally formed during the molding process as part of a unitary, one-piece construction.
For example, the molded plastic table top may include one or more depressions (also
referred to as "tack-offs") and the depressions may be designed and positioned to
increase the strength of the table top and/or interconnect spaced apart walls of the
table top. The depressions may also be sized and configured to create a structure
with particular characteristics and qualities, such as a table top with generally
uniform strength, rigidity and/or structural integrity. The molded plastic table top
may also include other features such as structures that increase the strength, rigidity
and/or torsion resistance of at least a portion of the table top.
[0016] The table may include components that can be quickly and easily manufactured. For
example, the legs and/or side rails of the frame may be relatively straightforward
to manufacture. In addition, the legs and/or side rails of the frame may be quickly
and easily attached to the table top, which may reduce manufacturing costs. The table
may also be constructed from only a few parts and a limited number of fasteners may
be required, which may allow the table to be quickly and easily assembled by the manufacturer,
retailer and/or consumer.
[0017] Advantageously, the stacked tables may be disposed in an aligned configuration. For
example, one table may be easily aligned with an adjacent table, which may facilitate
shipping, storage and/or display of multiple tables. Significantly, the aligned tables
may be disposed vertically, horizontally, or at suitable angles depending, for instance,
if the tables are to be shipped, stored, displayed, or the like. If desired, the stacked
tables may interlock or have a tendency to stay together. For instance, a friction
or interference fit between adjacent stacked tables may tend to maintain the tables
in a stacked configuration. If the tables have a penchant to stay together, this may
help reduce damage to the tables during shipping, storage and/or display.
[0018] The table may be nested with an adjacent table to reduce space. Significantly, the
nested tables may allow the tables to be stored in a smaller area, which may substantially
reduce storage and shipping costs. The nested tables may also allow a greater number
of tables to be stored in the same area as conventional tables that do not nest together.
In addition, the nested tables may help protect the tables from damage. For example,
because an upper portion of a table may be disposed within a lower portion of an adjacent
table, that may help prevent the table from being damaged. The nested tables may further
have table tops that are the same or substantially the same as conventional tables,
which may indicate to consumers that the tables have similar appearances and characteristics
such as strength, structural integrity and the like. The nested tables may also have
the same general footprint as a conventional table, but the nested tables may allow
significantly more tables to be disposed on a pallet or in a shipping container, and/or
allow the same number of tables to be disposed in a significantly smaller space.
[0019] The nested tables may have a significantly reduced height in comparison to conventional
tables that do not nest together. For example, known tables may have a table top with
a height of about 5.4 cm (2.125 inches) and thirty (30) of these known tables could
be stacked with a height of at least 1.62 m (63.75 inches). An exemplary embodiment
of a nested table may have a table top with a thickness of about 5.1 cm (2.0 inches),
but may overlap with an adjacent table by about 0.64 cm (0.25 inches) so that the
height of the stacked portion of a nested table may only be about 4.45 cm (1.75 inches).
Thus, the height of thirty nested tables may be reduced to about 1.34 m (52.75 inches)
because adjacent tables may nest together. In particular, because a portion of a table
may be disposed within or overlap with an adjacent table in the nested configuration,
that may allow the overall height of the nested tables to be decreased. Therefore,
in this exemplary configuration, the height of the table in the nested configuration
may only be about 4.45 cm (1.75 inches). Consequently, the height per nested table
may be between about 0.95 cm (0.375 inches) and 0.64 cm (0.25 inches) less than previously
known tables. This may allow more tables to be disposed in a stacked configuration,
which may greatly increase the number of tables that can be stacked on a pallet or
shelf, or disposed in a shipping container or truck.
[0020] A conventional table may have a blow-molded plastic table top with a height of about
5.1 cm (2.0 inches) and a frame with a height of about 4.1 cm (1.625 inches). The
height of the frame for this type of conventional table is more than eighty percent
(80%) of the height of the table top in order to create a table with the needed strength
and rigidity. The frame for this type of conventional table may have a rectangular
cross-sectional configuration, which may help create a beam-type structure with two
opposing walls that are separated by a generally constant distance. It was known that
a decrease in the height of the frame may result in a decrease in strength of the
table. It was also known that a decrease in the width of the frame may result in undesirable
twisting and/or bending in the table. In contrast to these known tables, the frame
may allow the nested tables to have the same general height and appearance as a conventional
table, and the same general strength and structural integrity as a conventional table,
but allows the tables to be nested together. This may also allow consumers to immediately
deduce that the nested tables have the same general strength, rigidity and torsion
resistance as a conventional table because the tables may have generally the same
size and footprint. The frame of the nested tables, however, significantly decreases
the height of two or more stacked tables. Because the nested tables may have a significant
decrease in height in the nested configuration, this may result in considerable space
savings that may be very important to the manufacturer during the manufacturing and
shipping process; to the retailer when storing or displaying multiple tables; and/or
to a consumer purchasing, transporting or storing more than one table.
[0021] The table may be sized and configured to be nested with at least one other table
such that the height of the nested tables is decreased by more than ten percent (10%).
For example, the height of a single table may be about 5.1 cm (2.0 inches). When the
table is nested with another table, the table may only contribute a height of about
4.4 cm (1.75 inches) to the nested tables because a portion of the tables are nested
together. In this embodiment, the nested tables result in a decrease in height of
each stacked table by about 0.6 cm (0.25 inches). Therefore, the height of a table
in the stacked configuration may be about twelve and one-half percent (12.5%) less
than in the non-stacked configuration. Advantageously, this may allow tables to be
more efficiently stored, transported and displayed because less space may be required.
In another example, a standard pallet or shipping configuration may include twenty-one
(21) conventional tables, but the tables with the nesting features disclosed herein
may allow twenty-seven (27) or twenty-nine (29) tables to be disposed on a standard
pallet or in a typical shipping configuration. If twenty-seven tables are disposed
on a pallet or in a standard shipping configuration rather than twenty-one tables,
then approximately twenty-eight percent (28%) more tables can be stored, transported
or displayed. If twenty-nine tables rather than twenty-one tables are disposed on
a pallet or in a standard shipping configuration, then a thirty-eight percent (38%)
increase in the number of tables may be realized. Advantageously, this may result
in significant savings and cost advantages because, for example, considerably more
tables may be stored, transported or displayed in the same area; or the same number
of tables may be stored, transported or displayed in an area that is at least twenty-five
percent (25%) smaller. When large volumes of tables are being transported, such as
in a standard or high-capacity shipping container, this may result in sizeable cost
savings and advantages.
[0022] The table may be nested with an adjacent table such that the height of a nested table
is decreased by approximately twenty percent (20%). For example, the height of a conventional
blow-molded plastic table top is typically 5.1 cm (2.0 or more inches). The table
top height of a nested table may be about 5.1 cm (2.0 inches) when it is not nested
with another table, but the height of a stacked portion of the table may only be
between about 3.8 cm (1.5 inches) and 4.45 cm (1.75 inches) when nested with another
table. This may result in a significant reduction in height between twelve and one-half
percent (12.5%) and twenty-five percent (25%) when two or more tables are nested together.
In particular, if the nested tables are decreased in height by about twenty percent
(20%), then the tables may have a height of about 4.1 cm (1.6 inches) in the nested
configuration. Furthermore, the nested table may have a weight that is less than that
of comparable conventional tables. The nested table may therefore contribute less
weight when stacked or nested with one or more other tables and this may allow a greater
number of nested tables to be stacked without additional weight.
[0023] The table may include a receiving portion, such as a groove, channel or recessed
portion, in an upper portion of the table top sized and configured to receive a portion
of an adjacent table to facilitate nesting of the tables. For example, the receiving
portion may be disposed about an upper surface and/or outer perimeter of the table
top. In greater detail, the receiving portion may have a generally L-shaped configuration
with a lower surface generally parallel to the upper surface of the table top and
a sidewall generally perpendicular to the upper surface of the table top. A portion
of an adjacent table may be disposed in the receiving portion to allow the tables
to be nested together. In particular, a portion of the frame, such as a projection
or flange, and/or a portion of the table top, such as an edge or corner, may be disposed
in the receiving portion. In greater detail, a portion of the side rails of the frame
may be disposed in the receiving portion along the sides of an adjacent, stacked table.
A lower portion of a lip and/or the corners of the table top may also be disposed
in the receiving portion of the adjacent, stacked table.
[0024] The table may include a frame sized and configured to facilitate stacking of the
tables. For example, the frame may include an upper portion generally aligned with
a lower portion of the table top. The upper portion of the frame may be disposed in
a frame receiving portion in the lower portion of the table top and this may help
maintain the frame in the desired position. The frame may also include a lower portion
sized and configured to contact an upper portion of an adjacent, stacked table. The
frame may further include an engaging portion sized and configured to be disposed
in the receiving portion of an adjacent, nested table. The engaging portion may include
a downwardly extending flange or projection sized and configured to fit within a receiving
portion, such as a groove or cutout, of the adjacent, nested table. Advantageously,
the frame may directly support at least a portion of the weight and/or forces applied
to the tables in the nested configuration, which may help prevent damage to the tables.
For example, when the tables are stacked in a horizontal configuration, the frame
of one table may contact the adjacent, stacked table in a manner that allows the stacked
tables to support a significant amount of weight without damage to the tables. This
may allow ten, twenty, thirty or more tables to be disposed in a stacked configuration
without damaging any of the tables. In addition, if the engaging portion of the frame
is disposed in a receiving portion of an adjacent table, that may facilitate stacking,
storing and/or shipping of the tables because that may help maintain the tables in
the stacked configuration and ensure the weight is properly and/or evenly distributed.
[0025] The table may be sized and configured to nest with an adjacent, stacked table in
which a weight or load is supported in multiple areas, in different locations and/or
by different surfaces. Advantageously, the multiple contact areas may allow stresses
and forces to be disposed over a larger area and that may help prevent damage to the
tables. For example, the table may include one or more contact areas sized and configured
to contact the upper surface of the adjacent table top.
[0026] In greater detail, the side rails of the frame may include a lower portion, such
as a planar contact surface or load bearing surface, disposed generally parallel to
an upper surface of the table top. In addition, the side rails of the frame may include
an engaging portion, such as a downwardly extending flange or projection, sized and
configured to be disposed in a receiving portion of the adjacent, stacked table. A
lower portion of the flange may contact a lower surface of the receiving portion,
which may be another load bearing surface. Additionally, the table may include other
portions, such as corners or lips, sized and configured to be disposed in the receiving
potion of the adjacent, stacked table. For instance, the corners and/or lips may include
a compression edge that contacts the lower surface of the receiving portion, which
may also be load bearing surfaces. When two or more tables are nested together, the
multiple contact areas may facilitate stacking of the tables without marring or otherwise
damaging the tables.
[0027] The table may include a table top with one or more portions formed from compression
molded plastic. For example, a portion of the corners and/or lip may be compression
molded during a blow-molding process. Advantageously, the compression molded corners
and/or lip may help create stronger, more rigid and/or more impact resistant structures,
which may increase the durability and usefulness of the table. Significantly, compression
molding may allow a portion of the corners and/or lip to be relatively thin because
there is little or no gap or space between the walls of the compression molded plastic
structure. The compression molded corners and/or lip may also be sized and configured
to fit within a receiving portion of an adjacent, stacked table, which may facilitate
stacking and nesting of the tables. The compression molded portions may further be
sized and configured to contact a portion of the frame. For instance, a compression
molded portion may be disposed along at least a portion of the
lip and the side rail of the frame may contact or abut the compression molded portion,
which may help position and maintain the frame in the desired position.
[0028] The table may include a compression edge. For example, if the table top is constructed
from blow-molded plastic, the compression edge may be formed by the outer wall being
folded onto itself such that the compression edge has a thickness approximately equal
to twice the outer wall thickness. The compression edge may be disposed about all
or a portion of the perimeter of the table top, such as the edges and/or corners.
Advantageously, the compression edge may help provide increased strength, stiffness,
structural integrity and/or impact resistance. The compression edge may also be sized
and configured to be at least partially disposed in the receiving portion of an adjacent,
nested table.
[0029] The table may include a compression edge with different sizes. For example, the corners
of the table top may include a compression edge that has a different size than a compression
edge extending along the sides and/or ends of the table top. In particular, the table
top may include a downwardly extending lip and the corners may include a compression
edge that has a height generally equal to or greater than a majority of the height
of the lip. The corners may also include a compression edge with a height generally
or at least substantially equal to the height of the lip. The sides of the table top
could include a compression edge that is smaller than the compression edge in the
corners. For instance, the sides of the table top could include a compression edge
with a height that is generally equal to or less than the height of the lip. The height
of the compression edge disposed along the sides and/or ends of the table top may
also be significantly smaller than the height of the lip. In an exemplary embodiment,
the compression edge disposed along the sides of the table top may have a height between
about 0.32 cm (0.125 inches) and about 0.64 cm (0.25 inches), and the corners may
include a compression edge with a height between about 0.6 cm (0.25 inches) and about
1.2 cm (0.5 inches). The compression edge along the ends of the table top may have
a height between about 0.6 cm (0.125 inches) and about 1.2 cm (0.5 inches). Thus,
the compression edge in the corners and/or ends of the table top may be two times
or more times larger than the compression edge along the sides. The compression edges
in the corners may be much larger, if desired, such as three, four, five or more times
the height of compression edge along the sides and/or ends.
[0030] The table may include a handle or grip disposed in one or both ends of the table
top. The handle may consist of a recess or opening in the downwardly extending lip
of a table top and the handle may be integrally formed with the table top as part
of a unitary, one-piece construction. Preferably, the handle is sized and configured
to facilitate moving and transporting the table. In addition, the handle may assist
in separating the tables in a stacked configuration. The table top may further include
recesses or openings that may allow a portion of the frame to be disposed along the
sides of the table top. For example, the sides of the table top may include openings
that allow at least a portion of the frame to be exposed. Therefore, the ends of table
may include openings in the lip that form the handles and openings in the sides that
allow a portion of the frame to be exposed. Other portions of the frame may be inset
and/or disposed inwardly from an outer perimeter of the table top, which may help
protect the frame from damage.
[0031] The table may include a frame with a first portion disposed along one side of the
table top and a second portion disposed along a second side of the table top. In particular,
the frame may include a first side rail disposed along a first side of the table top
and a second side rail disposed along a second side of the table top. The side rails
may extend along a length and/or width of the table top and the
side rails may help support the table top and/or facilitate connection of the legs
to the table top. Each side rail may include a body and the body may be elongated,
have one or more engagement surfaces, and may be constructed from relatively strong
materials such as metal. In greater detail, the body of the side rails may be disposed
at least proximate a downwardly extending lip of the table top and the body of the
side rails may be disposed generally vertically relative to the table top. The side
rails may also include an upper portion and a lower portion. For example, the upper
portion of the side rail may include a flange that extends inwardly at angle, such
as a right angle, to the body. The upper portion of the side rail may also include
a second flange, such as an inner flange, that extends downwardly. This inner flange
may be disposed at least proximate an end of the upper portion of the side rail and
it may be disposed generally parallel to the body of the side rail. The lower portion
of the side rail may include a flange that extends outwardly towards an outer portion
of the table top. The lower portion may also include a downwardly extending portion,
such as a flange or projection, which may be disposed perpendicular to the lower portion
of the side rail. If desired, the downwardly extending portion may have twice or double
the thickness in comparison to other portions of the frame. In particular, the downwardly
extending portion may be folded or bent back upon itself and include an upwardly extending
portion sized and configured to contact a portion of the table top, such as a lower
surface of the downwardly extending lip.
[0032] The table may include a table top with one or more receiving portions sized and configured
to receive a portion of the frame. For instance, the table top may include a frame
receiving portion sized and configured to receive an upper portion of the side rail
of the frame. In addition, the table top may include a sidewall sized and configured
to contact the body of the side rail and a lip sized and configured to contact the
lower portion of the side rail. If desired, an inner wall of the lip
may form at least a portion of the sidewall and a lower portion of the lip may contact
the lower portion of the frame. Advantageously, the table top may be sized and configured
to help position and/or maintain the side rail in a desired position. Additionally,
the table top may be sized and configured to help prevent the side rail from bending,
twisting or otherwise moving, which may help create a stronger and sturdier table.
[0033] The table may include a frame with one or more generally L-shaped and/or U-shaped
sections. For instance, the side rails of the frame may include an upper portion with
a generally inverted U-shaped configuration and a lower portion with a generally U-shaped
configuration. The upper portion of the frame may be sized and configured to be disposed
in a frame receiving portion disposed in a lower or underneath portion of the table
top. The lower portion of the frame may be sized and configured to contact an adjacent
table in a stacked, nested configuration. In particular, the lower portion of the
frame may include a lower surface sized and configured to contact an upper surface
of adjacent table in the nested configuration. The lower portion of the frame may
further include an engaging portion sized and configured to be disposed in a receiving
portion of an adjacent table in the nested configuration.
[0034] The table may include a frame that facilitates nesting and stacking of a plurality
of tables. The frame may also help support a downwardly extending lip of the table
top. For example, the frame may support an inner surface, lower surface and/or outer
portion of the lip. In addition, the frame may provide multiple contact areas, such
as a planar engagement surface and an engaging portion or flange, which may allow
a load to be distributed over multiple areas when multiple tables are nested together.
This may allow more tables to be disposed in a stacked configuration and/or help prevent
damage to the tables.
[0035] The table may include a frame with an inwardly disposed portion and an outwardly
disposed portion. For example, the frame may include a first portion disposed towards
an inner portion of the table top and a second portion disposed towards an outer portion
of the table top. The inwardly disposed portion may be at least partially or substantially
disposed inwardly from a downwardly extending lip of the table top while the outwardly
disposed portion may contact and/or enclose at least a portion of the lip.
[0036] The table may include a frame and a portion of the frame may be disposed along an
edge or perimeter of the table top. For example, the table top may include a lip with
an opening and an outer portion of the frame may be disposed in or at least proximate
the opening. Advantageously, this may allow a portion of the frame to be exposed and
the exposed portion of the frame may indicate to consumers the table is strong, high-strength
and durable. The exposed portion of the frame may be generally aligned with and/or
spaced inwardly from an outer perimeter of the table top. The exposed portion of the
frame may also be generally aligned with a lower portion of the table top, such as
a lower surface of the corners, lip and/or ends. In greater detail, an opening may
be disposed in the lip along the sides of the table top and the exposed portion of
the frame may be disposed in and/or generally aligned with the openings. The lower
portion of the frame may be aligned with a lowermost portion of the table top or it
could extend outwardly more than other portions of the table top. Thus, in this configuration,
the lower portion of the frame may form the lowermost portion of the table top. The
exposed frame may also create a table with improved aesthetics and/or style. For instance,
the exposed frame may provide a color contrast with the table top. That is, the table
top may be one or more colors and the frame may
have one or more different colors to create a table with a stylized appearance or
an aesthetically pleasing design.
[0037] The table may include a table top with openings to allow a portion of a frame to
be exposed and/or disposed proximate a perimeter of the table top. For example, the
table top may include one or more openings that allow at least a portion of the frame
to be exposed and disposed at least proximate the perimeter of the table top. These
openings may extend along at least a majority of the length of the table top. The
table top may also include one or more openings for a handle in the ends of the table
top. The openings along the sides of the table top are preferably much larger than
the openings in the ends of the table top, by a factor such as five, ten, twenty or
more times the length of the opening for the handle.
[0038] The table may include a frame that contacts, engages and/or supports a lip and/or
outer perimeter of the table top. Advantageously, if the frame is disposed along the
outer edges of the table top, then the frame may provide increased support for the
edges or extremities of the table top. In addition, if a portion of the frame is disposed
below or proximate the lip, then the frame may help prevent the table top from being
damaged. For example, the frame may absorb impacts or forces that otherwise may damage
the table top.
[0039] The table may include a frame with an engaging portion, such as a protrusion or flange,
which facilitates nesting and stacking of the tables. The protrusion may be generally
aligned with and/or disposed proximate a lower portion of the lip, such as a compression
edge. Because the protrusion and compression edge may have double wall thicknesses,
this may help prevent the table from being damaged. In greater detail, the protrusion
may be formed by bending or folding the frame back upon itself so that it includes
two adjacent, parallel walls and a
rounded end. The compression edge may include an inner wall and an outer wall that
are adjacent, parallel and preferably in contact. If desired, the protrusion and compression
edge may include lower surfaces that are generally aligned and disposed in the same
plane. Advantageously, the double wall thicknesses of the frame and lip may help prevent
that table top from being damaged. Additionally, the double wall thicknesses may promote
stacking and nesting of the tables because, for example, it may allow a strong, thin,
resilient and/or damage resistant portion of a table to be disposed in a receiving
portion of an adjacent table.
[0040] A frame for the table may be less likely to undesirably bend or deform. For example,
the frame may have a configuration that resists twisting or rotating when a load or
force is applied to the frame. In addition, the frame may provide more balanced loading
on the table when a load or force is applied. For instance, the frame could include
multiple bends or angles, such as a plurality of right or 90° angles. Advantageously,
the multiple right angles may help increase the strength of the frame, resist twisting
or rotating when a load or force is applied to the frame, and/or provide more balanced
loading. The frame could also include one or more portions that are bent back or folded
with a 180° angle such that portions of the frame have twice the thickness. This may
also help increase the strength of the frame, resist twisting or rotating when a load
or force is applied to the frame, and/or provide more balanced loading.
[0041] The table may include a frame that is at least partially disposed in one or more
receiving portions in the table top. The table top may also include one or more receiving
portions that are sized and configured to receive other components of the table such
as cross members, cross bars and the like. For example, the table top may include
receiving portions that are sized and configured to receive an upper portion of a
support structure. The table top may also include receiving portions
that are sized and configured to receive a portion of the legs when the legs are in
the collapsed position. In addition, the frame may include one or more openings that
are sized and configured to facilitate attachment of the legs to the table. For instance,
the frame may include openings that are sized and configured to receive the ends of
a cross member and/or upper portion of a support structure. Depending upon the shape
and arrangement of the frame, the openings in the frame may be circular or non-circular
configuration. By extending the ends of the cross tube through openings in the frame,
the legs may be securely connected to the table top.
[0042] The table may include a frame and leg assemblies that are constructed from relatively
strong and durable materials such as metal, steel and the like. It will be appreciated,
however, the frame and leg assemblies may be constructed from other materials with
suitable properties and characteristics. In addition, the table, frame, leg assemblies
and the like may have a variety of other suitable shapes, sizes, configurations and
arrangements depending, for example, upon the intended use of the table.
[0043] The table may include a table top with a plurality of depressions. The plurality
of depressions may be closely spaced and may cover at least a majority, substantially
all, virtually all or all of a lower surface of the table top. The plurality of depressions
may be disposed in a generally uniform pattern in which the depressions have generally
the same size, shape configuration, orientation and arrangement. In addition, at least
a majority of the depressions in the plurality of depressions may be spaced apart
from one or more adjacent depressions by a generally consistent or uniform distance.
Advantageously, the depressions may help create a table top with increased strength,
rigidity and/or structural integrity. In addition, if the depressions in the plurality
of depressions are generally uniformly spaced and disposed
in a generally uniform pattern, that may help create a table top with generally uniform
characteristics.
[0044] The table top may include strengthening members, such as depressions, ribs, channels
and the like, disposed proximate and/or adjacent structural support members or features
of the table. For example, the table top may include a plurality of strengthening
members disposed proximate and/or adjacent the frame. In greater detail, the table
top may include one or more frame receiving portions that are sized and configured
to receive the side rails of the frame and the frame receiving portions may include
a plurality of strengthening members. When the frame is connected to the table top,
the frame may cover all or a portion of the strengthening members in the frame receiving
portion. The strengthening members in the frame receiving portions may be disposed
in different arrangements and/or configurations, which may be used to create areas
of increased strength and/or different characteristics. For instance, the strengthening
members may be disposed in first and second configurations. In particular, the first
configuration of strengthening members may be generally aligned in a first direction,
such as along the length of the table top, while the second configuration of strengthening
members may be generally aligned in a second direction, such as along a width of the
table top. The first configuration of strengthening members may provide greater strength
in one direction or location and the second configuration of strengthening members
may provide greater strength in a second direction or location. Because the strengthening
members can provide additional strength in different directions and/or locations,
that may allow relatively strong, sturdy, stiff and/or rigid structures to be constructed.
[0045] The table top may include strengthening members with different configurations and/or
disposed in different locations to prevent or
minimize potential points of weakness, stress concentrations and the like. For example,
the strengthening members may be sized and configured to support areas of the table
top disposed outside of the frame. The strengthening members may also be sized and
configured to help prevent the table top from bending, collapsing or deflecting when
a load or force is applied to the table top. Further, the strengthening members may
be sized and configured to help prevent the table top from twisting or rotating relative
to the frame. Advantageously, because the strengthening members may help support portions
of the table top disposed above the frame and/or the edges; a strong, sturdy and well-supported
table may be created. This may further facilitate stacking and nesting of the tables
because, for example, the lower tables in the stack of tables may be unlikely to be
damaged by the weight of the stacked tables.
[0046] The table top may include one or more strengthening members disposed between and/or
connecting a frame receiving portion and an outer portion of the table top such as
a lip. In particular, one or more strengthening members may connect the frame receiving
portion and a portion of the lip, such as an inner wall or sidewall of the lip. In
greater detail, one or more strengthening members may be at least partially disposed
in the upper surface and/or sidewalls of the frame receiving portion and in at least
a portion of a sidewall of the lip. Because the strengthening members may connect
the frame receiving portion and the lip, the strengthening members may increase the
strength and/or structural integrity of the frame receiving portion and/or the lip.
Additionally, because the frame may cover at least a portion of the frame receiving
portion and the sidewall of the lip, these strengthening members may be generally
hidden from view.
[0047] The table top may include a plurality of strengthening members that are generally
aligned with one another. For instance, the strengthening
members may include a body that is generally aligned with an axis and each strengthening
member of the plurality of strengthening members may be generally aligned along the
same axis or parallel axes. Advantageously, because the strengthening members generally
aligned with an axis may have increased strength, structural integrity and/or other
characteristics in a particular direction, such as along the axis, aligning the strengthening
members along the same axis or parallel axes may help create a table top with generally
uniform properties and characteristics. The table top may further include another
plurality of strengthening members that are generally aligned along a different axis.
For example, the strengthening members disposed along the different axis may provide
increased strength, structural integrity and/or other characteristics along this axis.
Therefore, the strengthening members disposed along different axes may be used to
created portions of the table top with different characteristics. This may allow,
for example, some of the strengthening members in the frame receiving portion to be
disposed along a first axis, such as generally aligned with a length of the table
top, and other strengthening members to disposed along a second axis, such aligned
with a width of the table top. If desired, one or more of the strengthening members
may be sized and configured to help support the outer edges or sides of the table
top. For instance, the strengthening members may help prevent the outer edges of the
table top, which may not be directly supported by the frame, from unintentionally
bending, twisting or deflecting.
[0048] The table top may include strengthening members, such as ribs, disposed in an outer
edge or lip of the table top. For example, the table top may include a lip or edge
and a plurality of strengthening members may be formed in the lip. In particular,
the inner surface of the lip, such as a sidewall, may include a plurality of inwardly
extending strengthening members. In addition, these strengthening members may be at
least partially disposed in a frame receiving portion. Significantly, the
strengthening members may provide increased strength, stiffness, rigidity and/or structural
integrity to portions of the table top such as the portion of the table top disposed
above the frame and portions of the table top that extend beyond the frame such as
the lip. Advantageously, the strengthening members may also help prevent undesired
bending, twisting or deflecting of the table top.
[0049] The table top may include strengthening members and depressions with different shapes,
sizes, arrangements, orientations and/or configurations. For example, the majority
or substantially the entire center portion of the table top may include depressions
with generally uniform shapes, sizes, arrangements, orientations and configurations.
This may help create a table top with generally constant characteristics. The side
or edges of the table top, however, may include depressions or strengthening members
with different shapes, sizes, arrangements, orientations and/or configurations. For
instance, the edges of the table top may include a first group of depressions generally
aligned in a first direction and a second group of depressions generally aligned in
a second direction. If desired, the first direction may be generally perpendicular,
or at an angle such as about 30°, 45° or 60°, to the second direction. Because the
depressions or strengthening members may be aligned in different directions, portions
of the table top may have different characteristics. The strengthening members proximate
the edges of the table top may also have different configurations. For example, a
first group of strengthening members may be disposed in frame receiving portion and
a second group of strengthening members may be disposed in at least a portion of the
frame receiving portion and the lip. These strengthening members may support the portion
of the table top disposed above the frame and/or the portion of the table top extending
beyond the frame.
[0050] The receiving portion may be supported by strengthening members in the lower portion
of the table top. For example, the strengthening members may extend inwardly into
the lip along the sides of the table top and/or be disposed in the lower surface of
the table top. An inner portion of the strengthening members may contact, engage or
abut an inner portion of the receiving portion to provide increased strength, support,
rigidity and/or structural integrity for the receiving portion. Advantageously, this
may allow multiple tables to be stacked together because the receiving portion can
withstand a much greater amount of weight and force from the nested tables.
[0051] The table top may include a generally uniform pattern of depressions disposed in
a plurality of generally aligned rows that extend across a lower surface of the table
top. The table top may also include a plurality of channels in the lower surface that
are aligned with the rows of depressions. The lower surface of the table top may further
include a recess sized and configured to receive a structural support member such
as a cross bar. The channels may be disposed on both sides of the structural support
member recess and the ends of the channels may be disposed towards a side or end of
the table top. In addition, a plurality of depressions may be disposed in a lower
portion of the channels. The channels and depressions may be sized and configured
to provide extra strength, rigidity, structural integrity and/or torsion resistance
proximate the structural support members and/or the ends of the table top. In greater
detail, the channels may be aligned with the rows of depressions and the channels
may have different lengths. The width of the channel may be generally equal to the
width of the depressions in the lower surface of the table top. The depressions in
the
channels may have generally the same shape, configuration and arrangement as the pattern
of depressions in the lower surface, but with a smaller size. The depressions in the
channels may be disposed in generally the same pattern, arrangement and spacing as
the depressions in the lower surface, which may provide minimal or no disruption to
the support of the upper surface of the table top. This may allow the table top to
have generally uniform characteristics such as strength, rigidity, structural integrity
and/or torsion resistance.
[0052] The table may include a combination of features, aspects and the like, such as one
or more of those discussed above. For example, the table can include a frame with
engaging portions that are sized and configured to be disposed in a receiving portion
of an adjacent table when the tables are nested together. The table can also include
one or more compression edges sized and configured to be disposed in the receiving
portion of the adjacent, nested table. Thus, the frame and compression edges may facilitate
alignment and nesting of the tables in a stacked configuration. Further, the table
may include depressions or strengthening members disposed proximate or adjacent portions
of the frame, such as the side rails, and these structures may be sized and configured
to increase the strength, rigidity and/or structural integrity of the portion of the
table top disposed above and/or proximate the frame, and/or portions of the table
top that are not directly supported by the frame. In addition, the table may include
depressions and/or strengthening members disposed at an angle relative to the bottom
surface of the table top. For instance, the table may include strengthening members
in the lip disposed perpendicular to the lower surface of the table top. Additionally,
the table may include openings or recesses in the sides that allow a portion of the
frame to be exposed and readily visible when the table is being used or stored, and
openings in the ends to create handles.
[0053] The table may be constructed from one or more materials and processes. For example,
the table top may be constructed from molded plastic, such as blow-molded plastic.
The frame and legs may be constructed from high-strength materials such as steel.
In particular, the frame and/or legs may be constructed from high-strength, low-alloy
(HSLA) steel rather than traditional carbon steel. Importantly, HSLA steel may be
twenty to thirty percent (20 to 30%) lighter than carbon steel with the same strength.
Therefore, a table constructed with HSLA steel may be lightweight and have the same
strength as a conventional table constructed with a carbon steel frame because a smaller
gage of HSLA steel can be used. For example, sixteen (16) or eighteen (18) gage HSLA
steel may be used to construct the table, which is smaller than traditional steel.
HSLA steel, however, has not been previously used in this or other related industries
because it is much more expensive than traditional steel. That is, HSLA steel is cost
prohibitive. The reduction in the amount of steel required to manufacture the table
with one or more of the features disclosed herein, however, may be more than sufficient
to offset or justify the price of the more expensive HSLA steel. In particular, because
the amount of steel required to create the table with the disclosed features may be
significantly less than the amount of steel required to create a corresponding traditional
table, HSLA steel may no longer be cost prohibitive. Thus, because less steel may
be required and/or HSLA steel may be stronger and lighter weight, the table can be
manufactured with HSLA steel.
[0054] The table may include legs with support members that are widely spaced, which may
help create a sturdy table that is unlikely to undesirably move or wobble. The table
may also include a table top with various shapes, sizes, configurations and arrangements,
such as rectangular, square, circular, oblong and
the like. In addition, the table top may include one or more openings to allow, for
example, a portion of the frame to be exposed and/or to create a handle or grip.
[0055] The table top may be constructed from molded plastic and include an upper surface,
a sidewall and a receiving portion at least partially disposed in the upper surface
and the sidewall. The receiving portion may be sized and configured to receive an
engaging portion of an adjacent table when the tables are disposed in a nested configuration.
The table top may also include a lower portion and a plurality of strengthen members
may be disposed in the lower portion of the table top that are sized and configured
to support the receiving portion. Each strengthening member of the plurality of strengthening
members may include an inner portion sized and configured to support an inner portion
of the receiving portion. The upper surface, the sidewall, the receiving portion,
the lower portion and the plurality of strengthening members may be integrally formed
during a molding process as part of a unitary, one-piece construction.
[0056] The table top may include an upper surface formed by an outer wall of the molded
plastic table top and a lower portion formed by the outer wall of the molded plastic
table top. A receiving portion may be formed in the outer wall of the molded plastic
table top and a plurality of strengthening members may be formed in the outer wall
of the molded plastic table top. The receiving portion may be disposed about a perimeter
of the upper surface of the table top. In addition, if the table top is constructed
from blow-molded plastic, then the upper surface, the sidewall, the receiving portion,
the lower portion and the plurality of strengthening members may be integrally formed
as part of the unitary, one-piece construction during a blow-molding process. Additionally,
the receiving portion may be disposed between a plane generally aligned
with the upper surface of the table top and a plane generally aligned with a lower
surface of the table top, and the plurality of strengthening members may be disposed
between the plane generally aligned with the upper surface of the table top and the
plane generally aligned with the lower surface of the table top. The upper portion
of the strengthening members may contact the inner portion of the receiving portion
and one or more of the strengthening members may extend inwardly from the lower portion
of the table top and contact the receiving portion. One or more of the strengthening
members may also extend inwardly into a sidewall of a lip and an inner portion of
the one or more strengthening members contact the inner portion of the receiving portion.
One or more of the strengthening members may further extend upwardly from the lower
portion of the table top and contact the receiving portion. Finally, one or more of
the strengthening members may extend inwardly into a sidewall of a lip and an upper
portion of the one or more strengthening members may contact the inner surface of
the receiving portion, and one or more of the strengthening members may extend upwardly
from the lower portion of the table top and contact the receiving portion.
[0057] The table top may be constructed from molded plastic. The table top may include an
upper surface, a sidewall, a receiving portion at least partially disposed in the
upper surface and the sidewall that is sized and configured to receive an engaging
portion of an adjacent table when the tables are disposed in a nested configuration,
and a lower portion. A plurality of strengthening members may be disposed in the lower
portion of the table top may be sized and configured to support the receiving portion.
The upper surface, the sidewall, the receiving portion, the lower portion and the
plurality of strengthening members may be integrally formed during a molding process
as part of
a unitary, one-piece construction. The strengthening members may include a first plurality
of strengthening members disposed along a first portion of the table top, each strengthening
member of the first plurality of strengthening members may include an inner portion
sized and configured to support an inner portion of the receiving portion.
[0058] The strengthening members may also include a second plurality of strengthening members
disposed along a second portion of the table top, each strengthening member of the
second plurality of strengthening members may include an inner portion sized and configured
to support the inner portion of the receiving portion.
[0059] The first plurality of strengthening members may be disposed along a side of the
table top and the second plurality of strengthening members may be disposed in a corner
of the table top. In addition, the first plurality of strengthening members may extend
inwardly into a sidewall of a lip of the table top and an inner portion of the first
plurality of strengthening members may contact the inner portion of the receiving
portion. Additionally, the second plurality of strengthening members may extend upwardly
from the lower portion of the table top and an inner portion of the second plurality
of strengthening members may contact the inner portion of the receiving portion. Further,
the first plurality of strengthening members may be disposed generally parallel to
the lower portion of the table top and the second plurality of strengthening members
may be disposed generally perpendicular to the lower portion of the table top. The
first plurality of strengthening members may further comprise a depression disposed
between at least a majority of the strengthening members and the inner portion of
the receiving portion, and the second plurality of strengthening members further comprise
a depression disposed between at least a majority of the strengthening members and
the inner portion of the receiving portion.
[0060] The table top may be constructed from molded plastic and include an upper surface,
a sidewall and a receiving portion at least partially disposed in the upper surface
and the sidewall, the receiving portion may be sized and configured to receive an
engaging portion of an adjacent table when the tables are disposed in a nested configuration.
The table top may also include a lower portion and a plurality of depressions disposed
in the lower portion of the table top may be sized and configured to support the receiving
portion, and each depression of the plurality of depressions may include an inner
portion sized and configured to support an inner portion of the receiving portion.
The upper surface, the sidewall, the receiving portion, the lower portion and the
plurality of depressions may be integrally formed during a molding process as part
of a unitary, one-piece construction. One or more depressions of the plurality of
depressions may be disposed in a lip of the table top and an end of the depressions
may contact the inner portion of the receiving portion. In addition, one or more depressions
of the plurality of depressions may be disposed in a corner of the table top and an
end of the depressions may contact the inner portion of the receiving portion. Further,
the plurality of depressions may be disposed along one or more sides, one or more
corners and one or more ends of the table top, and the depressions may be sized and
configured to support the receiving portion in the sides, the corners and the ends
of the table top.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
[0063] The present invention is directed towards tables. It will be understood that, in
light of the present disclosure, the tables disclosed herein can have a variety of
shapes, sizes, configurations and arrangements. In addition, while the tables shown
in the accompanying figures are banquet or utility tables, it will be appreciated
the tables may have any suitable style or configuration such as round, personal, conference
or card tables. Further, the invention disclosed herein may be successfully used in
connection with other types of furniture and/or structures.
[0064] Additionally, to assist in the description of preferred embodiments of the tables,
words such as top, bottom, front, rear, right and left may be used to describe the
accompanying figures which may be, but are not necessarily, drawn to scale. It will
further be appreciated the tables can be disposed in a variety of desired positions
or orientations, and used in numerous locations, environments and arrangements. A
detailed description of preferred embodiments the table now follows.
[0065] As shown in Figures 1 and 2, an exemplary table 10 may include a table top 12 and
the table top may be constructed from molded plastic. The table top 12 may include
an upper portion 14, which may be aligned with an upper surface; a lower portion 16,
which may be aligned with a lower surface; and a perimeter 18. As shown in the accompanying
figures, a sidewall may be disposed about the perimeter 18 of the table top 12. The
upper portion 14 may be spaced apart from the lower portion 16 of the table top 12
by a distance, which may be a generally constant distance. The table top 12 may also
include a hollow interior portion disposed between the upper and lower portions 14,
16 of the table top. In addition, the table top 12 may include a lip 20, which may
extend downwardly from the lower portion 16 of the table top when the table top is
oriented with the upper surface facing up as shown in Figure 1. The table top 12 may
further include one or more sides 22, corners 24 and ends 26 depending, for example,
upon the shape and configuration of the table 10. The table top 12, including the
upper portion 14, the lower portion 16, the hollow interior portion, the lip 20, the
sides 22, the corners 24 and/or the ends 26, may be integrally formed as part of unitary,
one-piece structure during the molding process. If the table top 12 is constructed
from plastic, it may be formed in the desired shape by blow-molding, injection molding,
rotary molding, and/or other suitable processes. It will also be appreciated that
the table top 12 may be constructed using various materials such as wood, metal and
the like.
[0066] The table 10 may include a one or more support structures 28, which may be sized
and configured to support the table top 12 above a surface such as the floor or ground.
The support structures 28 may include one or more legs or supports 30 and the support
structures may be movable between an extended or use position and a collapsed or storage
position relative to the table top 12. As shown in the accompanying figures, the support
structures 28 may include a pair of legs or supports 30 and a connecting member 32
may interconnect the supports.
[0067] The table 10 may also include a frame 36 connected to the table top 12. If desired,
the support structures 28 may be connected to the frame 36 and the support structures
may be movably connected to the frame 36 to allow the legs 30 to move between an outwardly
extending or use position and a collapsed or storage position. For example, the support
structures 28 may include or be connected to cross members 38, 40 and the legs 30
may be connected to the cross members. The cross members 38, 40 may be connected to
the frame 36. In particular, the frame 36 may include elongated members, such as side
rails 42, 44, and the cross members 38, 40 may be connected to the side rails. It
will be appreciated that the cross members 38, 40 may also be part of the frame 36.
[0068] The support structures 28 and/or the legs 30, however, do not have to be connected
to the cross members 38, 40 or the frame 36. Instead, the support structures 28 and/or
legs 30 may be connected to any suitable portions of the table 10. It will also be
appreciated that the table 10 may include any suitable number of support structures
28 and/or legs 30 depending, for example, upon the intended use of the table. In addition,
it will be appreciated that the table top 12, the support structures 28 and the legs
30 may have various sizes, shapes, configurations and arrangements depending, for
example, upon the intended use of the table 10. It will further be appreciated that
the frame 36, the side rails 42, 44 and/or the cross members 38, 40 are not required,
and the table 10 may have other components, features, aspects, characteristics and
the like, if desired.
[0069] The table 10 may include first and second brace assemblies 46, 48, which may be connected
to the support structures 28. In particular, the brace assemblies 46, 48 may be connected
to the legs 30 and may be sized and configured to allow the legs to move between the
use and storage positions. As shown in Figure 2, the brace assemblies 46, 48 may include
a first portion 50A connected to the legs 30 and a second portion 50B connected to
a cross member 52 and/or the table top 12. The first and second portions 50A, 50B
may be interconnected to form the brace assemblies 46, 48.
[0070] The table 10 is preferably sized and configured to be stacked with one or more additional
tables. In particular, the stacked tables 10 are preferably nested together to reduce
the height of the stacked tables, which may allow the tables to be shipped, stored
and transported in a smaller area. This may result in significant cost savings to
the manufacturer, for example, because less storage space may be required and a substantial
reduction in transportation costs may be achieved. An exemplary embodiment of stacked
and nested tables is shown in Figures 13 and 14, which are discussed below in more
detail. Additional features, aspects and exemplary embodiments of stacked and nested
tables are shown in Assignee's
U.S. patent no. 8397652, entitled TABLES WITH NESTING TABLE TOPS;
U.S. patent no. 8408146, entitled FRAME
FOR A TABLE; and
U.S. patent no. 8347795, entitled TABLE.
[0071] The frame 36 may be sized and configured to facilitate nesting of the tables 10.
For example, as shown in Figure 2, the side rails 42, 44 of the frame 36 may be disposed
along the sides 22 of the table top 12. Advantageously, if the side rails 42, 44 are
disposed proximate the sides 22 of the table top 12, then the sides of the table top
may be supported by the frame 36, which may help create a strong and sturdy table
10. In addition, the side rails 42, 44 may be sized and configured to help transfer
forces towards a center portion of the table and away from the perimeter 18, which
also help create a strong and sturdy table 10.
[0072] As shown in Figures 1 to 4, the table 10 may include a handle 54 disposed at one
or both ends 26 of the table top 12. The handle 54 is preferably sized and configured
to facilitate moving and transporting the table 10. In addition, the handle 54 may
assist in separating the tables 10 in the nested configuration. The handle 54 may
consist of a recess or opening in the lip 20 of the table top 12 and the handle may
be integrally formed with the table top as part of a unitary, one-piece construction.
[0073] The table 10 may also include openings 56 disposed in the lip 20 along the sides
22 of the table top 12. The openings 56 may be sized and configured to allow a portion
of the frame 36, such as an outer surface 58 of the frame, to be visible or exposed
along the sides 22 of the table top 12. This may allow, for example, a consumer to
readily see the exposed surface 58 of the frame 36. Therefore, the table top 12 may
include openings 56 in the sides 22 to allow a portion of the frame 36 to be exposed
and openings in the ends 26 to form the handles 54. Thus, the table top 12 may include
openings in both the sides 22 and the ends 26, and the openings 56 in the sides may
be much larger than the handles 54 by a factor such as five, ten, twenty or more.
[0074] As shown in the accompanying figures, the table top 12 may include a plurality of
depressions 60. The depressions 60 may be sized, shaped, configured and arranged to
provide increased strength, stiffness and/or rigidity to the table top 12. The depressions
60 may also cover the majority, substantially all or the entire lower portion 16 of
the table top 12. In addition, the depressions 60 may have a generally uniform shape,
size, configuration and arrangement. The depressions 60 may further have an elongated
shape that is aligned with an axis and the depressions may be aligned in a series
of rows and columns that extend along the length and width of the table top 12. Additionally,
the depressions 60 in adjacent rows and columns may be offset, and the distance between
adjacent depressions in the rows and columns may be generally the same. For example,
the distance between adjacent depressions in each row or column may be generally constant
or the same. The distance between adjacent rows and columns may also be generally
constant or the same.
[0075] The depressions 60 may be used to create a table top 12 with generally uniform characteristics
or qualities. For example, if the depressions 60 are consistently spaced, that may
allow an upper surface 62 of the table top 12 to be uniformly supported. In addition,
if the depressions 60 are separated by a generally constant distance, which may be
measured from a center of one depression to a center of an adjacent depression, that
may create a table top 12 with more uniform characteristics or qualities. The distance
between adjacent depressions 60 may be measured longitudinally, laterally or at an
angle depending, for example, upon the arrangement of the depressions.
[0076] The depressions 60 may also be disposed in a pattern and the depressions may be generally
aligned and/or disposed in predetermined locations within the pattern. The pattern
may include, for example, a number of rows 64 and/or columns 66 of depressions 60.
The rows 64 could be disposed along a length of the table top 12 and the columns 66
could extend along a width of the table top. The depressions 60 may also be disposed
in other suitable forms and patterns, and may have other shapes, sizes, configurations
and arrangements, depending, for example, upon the intended use of the table 10.
[0077] A plurality of depressions 60 may also be disposed proximate the connection of the
frame 36 and table top 12. These depressions 60 proximate the frame 36 may have the
same size, shape, configuration and arrangement as the depressions in the pattern.
The depressions 60 proximate the frame 36 may also have other sizes, shapes, configurations
and/or arrangements as discussed in more detail below. A plurality of depressions
60 may also be disposed between the side rails 42, 44 of the frame 36 and an upper
surface 62 of the table top 12. Advantageously, the depressions 60 may help support
the portion of the table top 12 disposed above the side rails 42, 44 of the frame
36, which may help prevent the table top from undesirably sagging or otherwise deforming.
The depressions 60 may also help prevent portions of the table top 12 disposed above
the side rails 42, 44 of the frame 36 from undesirably bending or collapsing if a
load or force is applied to that portion of the table top.
[0078] The depressions 60 may also have different characteristics depending, for example,
upon the particular configuration of the depressions. For example, the depressions
60 may have an elongated length and a depression may have increased strength along
its length. The depression 60 may also have a non-circular configuration with increased
strength in one direction in comparison to another direction. Advantageously, if the
depressions 60 have different characteristics, then the depressions can be arranged
or configured so the structure has certain characteristics. In particular, the depressions
60 may be arranged into a pattern to maximize certain characteristics and/or create
a structure with generally uniform characteristics. For instance, the pattern may
include generally uniformly spaced depressions 60 that are separated by a generally
constant distance and/or disposed in standardized arrangement. A consistent arrangement
of the depressions 60 may help create a structure with uniform characteristics. For
example, a generally constant pattern of depressions 60 may create a structure with
generally uniform strength and structural integrity.
[0079] The table 10, the table top 12, the depressions 60 and other components of the table
may have a variety of suitable shapes, sizes, configurations and arrangements, such
as disclosed in Assignee's
U.S. patent no. 7,069,865, entitled HIGH-STRENGTH, LIGHTWEIGHT BLOW-MOLDED PLASTIC STRUCTURES, issued July
4, 2006. In addition, the table 10, the table top 12 and the depressions 60 may have
other suitable features and configurations, such as disclosed in Assignee's U.S. patent
publication no.
US 2006-0230989, entitled HIGH-STRENGTH, LIGHTWEIGHT BLOW-MOLDED PLASTIC STRUCTURES, filed March
9, 2006.
[0080] The table top 12 may also one or more strengthening members 70, which may be disposed
proximate the ends 26 of the table top. The strengthening members 70 may also be formed
in the lip 20, the sides 22 and/or the corners 24 of the table top 12. Advantageously,
the strengthening members 70 may increase the strength, rigidity, structural integrity
and/or impact resistance of the table top 12. Additional exemplary tables, table tops,
depressions and strengthening members (along with other features, aspects and components)
are disclosed in Assignee's
U.S. patent nos. 7,111,563;
7,475,643;
7,814,844 and
8,033,228; which are each incorporated by reference in its entirety. It will be understood
the tables disclosed herein may have different shapes, sizes, configurations and arrangements;
and may include any suitable number and combination of features, aspects and components;
but none of the features, aspects or components may be required.
[0081] The table top 12 may include strengthening members, such as the depressions 60 and/or
the strengthening members 70, disposed at least proximate stress concentrations. For
example, strengthening members may be positioned to help strengthen the upper surface
62 and/or a lower surface 68 of the table top 12, and minimize stress concentrations,
such as may occur at the connection of the frame 36 and table top. In particular,
strengthening members may be sized and configured to increase the strength, stiffness
and/or rigidity of the table top 12 disposed above the 36 frame by minimizing unsupported
areas of the table top. Additionally, strengthening members may increase the strength,
stiffness and/or rigidity of portions of the table top 12 that extend beyond the frame
36. For instance, strengthening members may be sized and configured to help prevent
portions of the table top 12 from undesirably bending or twisting, such as the edges
that are disposed about the perimeter 18 of the table top 12.
[0082] As discussed above, strengthening members, such the depressions 60 and/or the strengthening
members 70, may have a particular size, shape, configuration and/or arrangement to
provide increased strength, rigidity and/or structural integrity. Thus, the strengthening
members may have a specific size, shape, configuration and arrangement depending,
for example, upon factors such as location, intended use, function and the like.
[0083] As best seen in Figure 5, the table top may include strengthening members 72 disposed
proximate a frame receiving portion 74 sized and configured to receive at least a
portion the frame 36. In particular, the frame receiving portion 74 may be sized and
configured to receive the side rails 42, 44 of the frame 36. The side rail 42 may
contact or abut an upper surface 76 of the frame receiving portion 74. The side rail
42 may also contact or abut an inner sidewall 78 and an outer sidewall 80 of the frame
receiving portion 74. The frame receiving portion 74 may be integrally formed in the
lower surface 68 of the table top 12 as part of a unitary, one-piece construction.
[0084] The strengthening members 72 may be sandwiched or disposed between an upper surface
of the side rail 42, 44 and the upper surface 62 of the table top 12. For instance,
the strengthening members 72 may include one end disposed proximate an upper surface
of the side rail 42, 44 and an opposing end contacting the upper surface 62 of the
table top 12. The strengthening members 72 may further be sized and configured to
facilitate air flow during the molding process, which may be particularly helpful
if the table top is constructed from blow-molded plastic because the frame receiving
portion 74 may extend inwardly from the lower surface 68 of the table top 12 and there
may be limited spaced between the upper portion of the frame receiving portion and
the upper surface of the table top 12.
[0085] As seen in Figures 5 and 7, the strengthening members 72 may be disposed in the upper
surface 76 of the frame receiving portion 74. The strengthening members 72 may extend
from the upper surface 76 of the frame receiving portion 74 to the upper surface 62
of the table top 12. As shown in the accompanying figures, each of the strengthening
members 72 may be a channel or rib that is formed in the upper surface 76 of the frame
receiving portion 74 that contacts or abuts the upper surface 62, but the strengthening
members may also be grooves, indentations, depressions or the like. The strengthening
member 72 may be entirely disposed between or confined within the inner sidewall 78
and the outer sidewall 80 of the frame receiving portion 74. While the strengthening
member 72 may have an elongated length as shown in the accompanying figures, the strengthening
members may also have other suitable configurations such as round, circular, oval,
oblong and the like.
[0086] The strengthening members 72 may be sized, shaped, configured and arranged to provide
increased strength, stiffness and/or rigidity to the table top 12. The strengthening
members 72 may also be used to create a table top 12 with more uniform characteristics
or qualities. Advantageously, the strengthening members 72 may help support the portion
of the table top 12 disposed above the side rails 42, 44, which may help prevent the
table top from undesirably sagging or otherwise deforming. The strengthening members
72 may also help prevent the portion of the table top 12 disposed above the side rails
42, 44 from bending or collapsing if a load or force is applied to that portion of
the table top.
[0087] As best seen in Figures 5 and 7, the table top 12 may include a first group or plurality
of strengthening members 72, which may be substantially or entirely disposed in the
upper surface 76 of the frame receiving portion 74. The strengthening members 72 may
have an elongated length that is disposed in a first direction, such as generally
perpendicular to the length of the table top 12 and located between the inner and
outer sidewalls 78, 80 of the frame receiving portion 74. The strengthening members
72 may have a generally constant or consistent spacing, size, shape, configuration
and/or arrangement. In addition, the strengthening members 72 may be disposed along
an axis and/or in a parallel configuration, and adjacent strengthening members in
the frame receiving portion 74 may be separated from one another by a generally constant
distance.
[0088] The table top 12 may also include a second group or plurality of strengthening members
82. The second plurality of strengthening members 82 may have generally the same size,
shape, configuration and arrangement. The second plurality of strengthening members
82 may also be separated by a generally consistent distance. As shown in the accompanying
figures, the first and second pluralities of strengthening members 72, 82 may have
different shapes, sizes configurations and/or arrangements. For example, the strengthening
members 72, 82 may be disposed at different angles, such as at right angles with respect
to one another, or in different directions. For instance, in this embodiment, if the
first plurality of strengthening members 72 is generally aligned with the length of
the table top 12, then the second plurality of strengthening members 82 may be generally
aligned with the width of the table top. If desired, the strengthening members 72,
82 may alternate between a strengthening member from the first plurality of strengthening
members and a strengthening member from the second plurality of strengthening members.
[0089] As shown in Figures 5 and 7, the strengthening members 72, 82 may have different
configurations. For example, the strengthening member 82 may be a rib or channel that
extends across the width of the frame receiving portion 74 and may be at least partially
disposed in one or more of the sidewalls 78, 80 of the frame receiving portion. If
the frame receiving portion 74 is aligned with the lip 20, the strengthening member
82 may also be formed in the lip, such as in an inner sidewall 84 of the lip. The
strengthening member 82 may be disposed perpendicular to the lip 20 or an edge of
the table top 12, such as the sides 22, and the strengthening members may be disposed
in a parallel configuration. The strengthening members 82 may be sized and configured
to help prevent bending or twisting of the outer portions of the table top 12 that
are not supported by the frame 36.
[0090] In greater detail, the strengthening member 82 may be formed in the inner sidewall
78 of the frame receiving portion 74 and the strengthening member may extend along
all or only a portion of the inner sidewall. The strengthening member 82 may also
spans the entire width of the upper surface 76 of the frame receiving portion 74.
Additionally, the strengthening member 82 may be formed in the outer sidewall 80 of
the frame receiving portion 74 and/or the sidewall 84 of the lip 20.
[0091] As best seen in Figure 5, the strengthening member 82 may have different sizes and
configurations. For example, some of the strengthening members 82 may be larger or
smaller. Advantageously, because the strengthening members 82 may be disposed in both
the frame receiving portion 74 and the lip 20, the strengthening members may help
connect the frame receiving portion and the lip. The strengthening members 82 may
also provide increased strength, stiffness and/or rigidity to these portions of the
table top 12. For instance, the strengthening members 82 may increase the strength,
stiffness and/or rigidity of the portions of the table top 12 that extend or are disposed
beyond the frame 36, such as the lip 20. In addition, the strengthening members 82
may be sized and configured to prevent the lip 20 from undesirably bending or twisting.
[0092] Therefore, in one exemplary embodiment, a first plurality of depressions or strengthening
members 72 and a second plurality of depressions or strengthening members 82 may be
disposed between the side rails 42, 44 and the upper portion 14 or upper surface 62
of the table top 12. As shown in Figure 9, the side rails 42, 44 may include an upper
portion or surface 86 that contacts the lower surface 68 of the table top 12. In addition,
the plurality of strengthening members 72 may be disposed between a first side 88A
and a second side 88B of the upper portion or surface 86 of the side rails 42, 44.
[0093] As discussed above, the depressions 60, the strengthening members 72 and the strengthening
members 82 may provide increased strength, rigidity and/or structural integrity. These
structures may also support portions of the table top 12 such as the portions disposed
above the side rails 42, 44 of the frame and portions that extend beyond the frame
36. Advantageously, this may allow the table top 12 to have more uniform characteristics.
[0094] As shown in Figures 9, 11 and 12, the table top 12 may include a receiving portion
90 that is sized and configured to facilitate nesting of the tables. The receiving
portion 90 may be at least partially disposed in the upper portion 14 or upper surface
62 of the table top 12, and may be sized and configured to receive an engaging portion
92 of an adjacent table when the tables are disposed in a nested configuration. The
receiving portion 90 is preferably disposed about the perimeter 18 of the table top
12. In particular, the receiving portion 90 is preferably disposed about the entire
perimeter 18 of the table top 12 including the sides 22, the corners 24 and the ends
26. Desirably, the receiving portion 90 may be disposed below a plane aligned with
the upper surface 62 of the table top 12. The receiving portion 90 may be integrally
formed with the table top 12 as part of a unitary, one-piece construction during the
molding process, if the table top is constructed from molded plastic. In greater detail,
the receiving portion 90 may be disposed at least proximate the intersection of the
upper surface 62 and an outer edge of the table top 12. Additionally, the receiving
portion 90 may have a generally L-shaped configuration that is open on two sides,
which may help facilitate alignment and nesting of the tables 10.
[0095] The engaging portion 92 may be a portion of the frame 36, such as a portion of the
side rails 42, 44, and/or a portion of the table top 12, such as a portion of the
lip 20, the sides 22, the corners 24 and/or the ends 26. If desired, the portions
of the lip 20, the sides 22, the corners 24 and/or the ends 26 disposed in the receiving
portion 90 may include compression edges. Therefore, the engaging portion 92 disposed
in the receiving portion 90 may include a combination of one or more portions of the
frame 36 and/or table top 12. The receiving portion 90 and engaging portion 92 may
have various shapes, sizes, configurations and arrangements, such as shown in Assignee's
U.S. patent no. 8397652, entitled TABLES WITH NESTING TABLE TOPS;
U.S. patent no. 8408146, entitled FRAME FOR A TABLE; and
U.S. patent no. 8347795, entitled TABLE.
[0096] As shown in the accompanying figures, the receiving portion 90 is preferably disposed
about the perimeter 18 of the table top 12 including the sides 22, the corners 24
and the ends 26. In addition, the receiving portion 90 may be at least partially disposed
in the upper surface 62 and edge of the table top 12, and the receiving portion may
be disposed below a plane generally aligned with the upper surface of the table top.
The receiving portion 90 may be integrally formed with the table top 12 as part of
a unitary, one-piece construction during the molding process, if the table top is
constructed from molded plastic.
[0097] As shown in Figure 14, the receiving portion 90 may have a generally L-shaped configuration
that is open on two sides, which may facilitate alignment and nesting of the tables
10. The receiving portion 90 is a groove or channel with a height and a width. For
example, a sidewall 106 of the receiving portion 90 may have a height of between about
0.25 inches (0.635 cm) and about 0.5 inches (1.27 cm), such as about 0.3 inches (0.762
cm) or 0.4 inches (1.016 cm) and a lower surface 106 of the receiving portion 90 may
have a width that is greater than the height by a factor such as two, three or more.
For example, the width may be approximately two times the height such that, in this
exemplary embodiment, if the height is about 0.25 inches (0.635 cm) then the width
may be about 0.5 inches (1.27 cm). The height and the width may also be approximately
the same. For instance, if the height is about 0.5 inches (1.27 cm), then the width
may also be about 0.5 inches (1.27 cm). It will be appreciated the width may also
be smaller than the height. Thus, for example, if the height is about 0.4 i inches
(1.016 cm), then the width may be about 0.3 inches (0.762 cm) or less. It will be
understood the height and/or the width of the receiving portion 90 may vary depending,
for example, upon the intended use of the table 10.
[0098] The receiving portion 90 may be supported by strengthening members and/or depressions
94 disposed in the lower portion 16 of the table top 12. As shown in Figure 11, the
strengthening members 94 include an inner portion 96 (such as an upper or inner surface),
that contacts, abuts or engages an inner portion 98 (such as an inner surface) of
the receiving portion 90. In greater detail, the strengthening members 94 extend inwardly
or horizontally relative to the lower portion 16 of the table top 12. For instance,
the strengthening members 94 may be disposed along the sides 22 and/or ends 26 of
the table top 12. In particular, the strengthening members 94 are disposed in the
inner sidewall 84 of the lip 20 and have a generally curved or arc-shaped configuration.
An inner surface of the strengthening member 94 is spaced apart from an outer wall
of the lip 20 and the inner portion 96 of the strengthening members contacts the inner
portion 98 of the receiving portion 90. For a table 10 that is about six (6) feet
(1.83 m) in length, thirty-two (32) strengthening members 94 may be disposed along
each side 22 of the table top 10. It will be understood additional or fewer strengthening
members 94 may be disposed along the sides 22 and/or ends 26 of the table top 12 depending,
for example, upon the length or intended use of the table 10.
[0099] As shown in Figures 4-7 and 10-11, for example, the strengthening members 94 may
be disposed in the sidewall 84 of the lip 20. The strengthening members 94 may also
be disposed in the corners 24, such as shown in Figures 2 and 12. Advantageously,
the strengthening members 94 may also consist of and/or be referred to as depressions.
Further, as discussed below, one or more depressions may be used to connect the receiving
portion 90 and strengthening members 94. In will be understood, in light of the present
disclosure, the strengthening members 94 may have different shapes, sizes, configurations
and arrangements depending, for example, upon the intended use of the table 10.
[0100] The strengthening members 94 may also be disposed at other angles and/or connected
to the inner portion 98 of the receiving portion 90 in different configuration and
arrangements. For example, as shown in Figure 12, the strengthening members 94 may
be disposed in the corners 24 of the table top 12. The strengthening members 94 in
the corners 24 may extend upwardly from the lower surface 68 of the table top 12.
In greater detail, the inner portion 96 of the strengthening member 94 in the corner
24 may contact, abut or engage the inner portion 98 of the receiving portion 90. In
particular, the inner portion 96 of the strengthening members 94 may contact the inner
portion 98 of the receiving portion 90, such as inner surface of a lower portion 100
and/or an inner surface the sidewall 102. Each corner 24 of the table top 12 may include
eight (8) connections between the strengthening members 94 and the receiving portion
90. It will be understood the table 10 may have any appropriate number of connections
between the strengthening members 94 and the receiving portion 90, the strengthening
members may be disposed in any suitable portions of the table top 12 and the strengthening
members may have other sizes, shapes, configurations and arrangements depending, for
example, upon the intended use of the table 10.
[0101] Advantageously, the strengthening members 94 may provide increased strength, support,
rigidity and structural integrity for the receiving portion 90. The strengthening
members 94 may also allow the receiving portion 90 to support a considerable amount
of weight or force. Significantly, this may allow a number of tables 10 to be disposed
in a nested configuration because, for example, the tables disposed in the bottom
of the stack may not be damaged by the weight of the tables. For instance, when the
tables 10 are nested together as shown in Figures 13 and 14, the engaging portion
92 may contact or abut the lower surface 104 and/or the sidewall 106 of the receiving
portion 90 and these may become load bearing surfaces. Because the strengthening members
94 may increase the strength, rigidity and/or structural integrity of the receiving
portion 90, this may allow a considerable number of tables 10 to be stacked and nested
together without damage to the receiving portion.
[0102] One or more depressions may also support the receiving portion 90. For example, one
or more depressions may connect the strengthening member 94 and the receiving portion
90. In addition, one or more depressions may be formed in the lip 20 and/or the lower
portion 14 of the table top 12, and the depressions may contact, engage or abut the
inner portion 98 of the receiving portion 90.
[0103] The table 10 may also include other structures that may increase the strength, rigidity
and/or structural integrity of the table top 12. For example, the lower surface 68
of the table top 12 may include one or more recesses 110 that are sized and configured
to receive a structural support member such as a portion of the support structure
28, the frame 36, the cross member 38, the cross member 40 and/or the cross member
52. For instance, as shown in Figure 16, a first cross member recess 112 may be sized
and configured to receive a portion of the cross member 38 and a second cross member
recess 114 may be sized and configured to receive a portion of the cross member 40.
A third cross member recess 116 may be sized and configured to receive the cross member
52 disposed proximate the center of the table top 12. The lower surface 68 of the
table top 12 may also include a first support structure recess 118 and a second support
structure recess 120 that are sized and configured to receive the support structures
28 in the collapsed or storage position. The recesses 112, 114, 116, 118 and 120 may
facilitate nesting of the tables 10 by allowing an upper portion of an adjacent stacked
table to be disposed in a lower portion of the table. The recesses 112, 114, 116,
118 and 120 may also help position the various components in the desired positions.
[0104] The lower surface 68 of the table top 12 may also include one or more channels 122,
which may be aligned in a parallel configuration. The channels 122 may have a width
generally equal to the width of the depressions 60 in the lower surface 68 and the
channels are preferably aligned with the depressions. Advantageously, because the
channels 122 may be aligned with and have generally the same width as the depressions
60, the channels may not disrupt or interfere with a pattern or arrangement of generally
uniformly disposed depressions. The channels 122, however, may have a width that is
larger or smaller than the width of the depressions 60, if desired.
[0105] As shown in Figures 15-19, a plurality of depressions 124 may be disposed in a lower
portion 126 of the channels 122 and the depressions may contact, abut or engage the
upper surface 62 of the table top 12. The depressions 124 may have the same general
pattern, spacing, size, shape, configuration and arrangement. In addition, the depressions
124 in the lower portion 126 of the channel 122 may be disposed in generally the same
pattern as the depressions 60 in the lower surface 68. Significantly, if the depressions
60, 124 are disposed in generally the same pattern, this may create a table top 12
with generally uniform characteristics such as strength, rigidity and structural integrity.
[0106] The channels 122 may have a variety of different lengths. For example, some of the
channels 122 may have a length that only allows a limited number of depressions 124,
such as three (3), to be disposed in the lower portion 126. Other channels 122 may
have a longer length that allows a great number of depressions 124 to be disposed
in the lower portion 126, such as ten (10) or twelve (12). Further, other channels
122 may extend from one end to the other end of the table top 12. It will be appreciated
that the channels 122 may have any suitable length.
[0107] The channels 122 may be sized, shaped, configured and/or arranged to increase the
strength, rigidity, structural integrity and/or torsion resistance of the table top
12. For example, the channels 122 may have opposing walls 128, 130 and the opposing
walls may increase the strength, rigidity, structural integrity and/or torsion resistance
of the table top 12. The lower portion 126 of the channel may also be spaced proximate
the upper surface 62 and that may increase the strength, rigidity, structural integrity
and/or torsion resistance of the table top 10.
[0108] The channels 122 are preferably disposed on both sides of a structural support member
such as the cross members 38, 40. In particular, the channels 122 preferably extend
through a cross member recess, such as the first and second cross member recesses
112, 114, and past both sides of the cross member recess. In addition, a depression
may be disposed at an intersection of one or more of the channels 122 and the recess
for the cross member. Additionally, the ends of the channels 122 are preferably disposed
proximate a portion of the table top 12 that is not directly supported by the frame
36. For example, the ends of the channels 122 may be disposed proximate the ends 26
of the table top 12, which may extend beyond the ends of the side rails 42, 44 and
the cross members 38, 40. In particular, a first end of each channel 122 of the plurality
of channels may be disposed proximate a first end of the table top, and the ends of
the channels may be generally spaced an equal distance from the first end of the table
top. The channels 122 may also have different lengths. Advantageously, the channels
122 and the depressions 124 may increase the strength, stiffness, rigidity and/or
structural integrity proximate the structural support members and accompanying recesses,
and the ends 26 of the table top 12. Significantly, this may prevent the ends 26 of
the table top 12 from rotating or moving downwardly relative to the cross member 38,
40 and/or ends of the frame 36, which may increase the torsion resistance of the table
top 12.
[0109] As seen in Figures 18 and 19, the lower surface 68 may be spaced a generally constant
distance apart from the upper surface 62 so that the table top 12 has a generally
constant height or thickness. The various structures disposed in the lower surface
68 in the table top 12 may have different heights. For example, the cross member recesses
112, 114, 116 may have a height that is slightly less than the thickness of the table
top 12. The frame receiving portion 74 may have a height that is smaller than the
thickness of the table top 12 and the height of the cross member recess 112. The lower
portion 126 of the channel 122 may also have a height that is smaller than the thickness
of the table top 12 and the height of the cross member recess 112. As shown in the
accompanying figures, the height of the frame receiving portion 74 and the channel
122 may be approximately the same. Thus, the height of the cross member recesses 112,
114, 116 may be between the height of the frame receiving portion 74 and the channel
122. Because the height of the frame receiving portion 74 and the channel 122 may
be about the same, and because the frame receiving portion may include the strengthening
members 72, 82 and the channel may include the depressions 124, the upper surface
62 of the table top 12 may have generally similar characteristics such as strength,
rigidity and structural integrity.
[0110] In this exemplary configuration, the upper surface 62 of the table top 12 may be
generally uniformly supported, which may allow the table top to have generally consistent
characteristics and qualities such as strength, rigidity, structural integrity and
smoothness of the upper surface. It will be appreciated that the table 10 and table
top 12 may also have other suitable features, aspects, configurations and the like,
such as disclosed in Assignee's
U.S. patent no. 8622007, entitled TABLE
WITH MOLDED PLASTIC TABLE TOP; and U.S. patent publication no.
US 2012-0266791, entitled TABLES TOP.
[0111] One of ordinary skill in the art may appreciate after reviewing this disclosure that
the tables disclosed herein may have a number of different aspects, features, characteristics
and configurations. Further, a table may have any suitable number of aspects, features,
characteristics and configurations depending, for example, upon the intended use of
the table.
[0112] Although this invention has been described in terms of certain preferred embodiments,
other embodiments apparent to those of ordinary skill in the art are also within the
scope of this invention. Accordingly, the scope of the invention is intended to be
defined only by the claims which follow.
