FIELD
[0001] The present disclosure relates to a collapsible supporting structure. More particularly,
the present disclosure relates to a collapsible bistro table that can be collapsed
into a compact position with the legs secured to the bottom surface of the table when
not in use, thereby allowing easy storage, package and transportation of the table.
BACKGROUND
[0002] A conventional folding or collapsible table is available for providing a support
surface in a use position while taking up less space in a storage position. However,
particularly in the case of smaller tables in which the supporting legs are generally
longer than the width or length of the table surface, the legs are often an inconvenience
in storage, package, and transportation because the legs must awkwardly and loosely
extend from the table surface in the storage position (e.g., it is difficult to keep
the legs in their storage positions). While one solution has been to wrap a rope or
cord around one or more table surfaces to secure the legs to the bottom surface of
the tables, this requires an undesired extra step, which adds time to packing and
storing multiple tables at a time.
[0003] What is needed therefore is a table that can be easily moved between a use and storage
position where the legs are easily secured to the bottom surface of the table when
not in use, thereby allowing easy storage, package and transportation of the table.
[0004] US-B-2675286 discloses a collapsible table with a detachable tray top. A collapsible table structure
is disclosed, comprising a leg frame having two pairs of leg members, a crossrod pivoting
the leg members together centrally thereof, upper ends of each pair of leg members
being joined by crossrods, a table top, a pair of rails fixed to the undersurface
of the table top, said rails being arranged adjacent side edge portions of the table
top, a pair of opposed sockets in said rails at one end portion thereof, two pairs
of opposed sockets in the other end portion of said rails, all of said sockets having
common spring clips, the crossords at the upper ends of said leg members being retained
in the first named sockets and one pair of the second named sockets when the table
is in set-up position, and the first named crossrod engaging the other of said second
named pair of sockets in support of the leg members in collapsed position on the undersurface
of said table top.

DETAILED DESCRIPTION
[0011] According to the present disclosure, a collabsible supporting structure supporting
structure may be one of a table, a chair, a bench, a stool, and a step-ladder. Referring
to FIGS. 1 - 16, a collapsible table 10 in accordance with the preferred embodiment
of the present disclosure includes a tabletop 12 having a planar top surface 14, a
bottom surface 16 opposite the top surface 14, a first end 18, a second end 20 opposite
the first end 18, a first side 22, and a second side 24 opposite the first side 22.
The tabletop 12 is preferably substantially square shaped as shown, but may also be
rectangular, oval, circular, or irregular shaped within the scope of the present disclosure.
The tabletop 12 is according to the invention formed from blow-molded plastic.
[0012] As shown best in FIGS. 2, 4, 10, and 12, the collapsible table 10 further includes
a first pair of collapsible legs 26 having a first leg 25 and a second leg 27 secured
to each other adjacent their top ends by a first support bar 28. In order to move
the first pair of collapsible legs 26 between a use position (as shown in FIGS. 1
- 8) and a storage position (as shown in FIGS. 9 - 16), the first support bar 28 is
pivotally connected to the bottom surface 16 of the tabletop 12 preferably adjacent
to the first end 18 by a hinge assembly. The particular type of hinge assembly is
not critical as long as it provides means for the first support bar 28 and associated
first pair of collapsible legs 26 to be rotated between use and storage positions
as explained below. In certain embodiments and referring to FIGS. 2, 4, 10, and 12,
the hinge assembly includes hinge pins (not shown) extending from opposite ends of
the the first support bar 28 and rotatably connected to frame members 30 disposed
adjacent to the first side 22 and second side 24 of the bottom surface 16 of tabletop
12. Alternatively, first support bar 28 is secured within one or more cylindrical
receivers that allow for rotation of the first support bar 28 in relation to the bottom
surface 16 of the tabletop 12. In preferred embodiments, first support bar 28 is substantially
non-removably secured to its hinge assembly. In other words, while the first pair
of collapsible legs 26 can be rotated with respect to the bottom surface 16 of the
tabletop 12, it is preferred that the first pair of collapsible legs 26 can be easily
disconnected from the bottom surface 16.
[0013] A second pair of collapsible legs 34 having a third leg 33 and a fourth leg 35 are
secured to each other adjacent their top ends by a second support bar 36. While the
first pair of collapsible legs 26 are preferably non-removably secured adjacent the
first end 18 of tabletop 12 as explained above, the second pair of collapsible legs
34 are preferably operable to be removably secured to the bottom surface 16 of tabletop
12 adjacent to the second end 20. In order to removably secure the second pair of
collapsible legs 34, the bottom surface 16 includes one or more appropriately positioned
and configured brackets 38 that together are operable to securely receive and release
the second support bar 36 as desired. It is noted that brackets 38 are configured
so as to not permit any substantial rotation of the second support bar 36 when the
bar 36 is received within the brackets 38. In preferred embodiments, the brackets
38 are molded into the bottom surface 16 of the tabletop 12 and each include cylindrical
receiving surfaces dimensioned and configured to receive a portion of the cylindrical
second support bar 36 in the use position. Referring to FIG. 4, in preferred embodiments,
the bottom surface 16 includes a first set of brackets 38a positioned to receive one
side of the second support bar 36 in the use position and a second set of brackets
38b positioned to receive the other side of the second support bar 36. Together, brackets
38a and 38b provide a "snap-fit" when inserting the second support bar 36 into the
brackets to secure the second pair of collapsible legs 34 to the bottom surface 16
of the tabletop 12. In alternate embodiments, each of the brackets 38 are horizontally
aligned and each include cylindrical tabs dimensioned and configured so that a cylindrical
support bar 36 is operable to "snap-fit" into the cylindrical tabs of each of the
brackets 38.
[0014] Referring to FIGS. 1, 7, and 8, the first pair of collapsible legs 26 are preferably
pivotally cross-connected with the second pair of collapsible legs 34 using pivot
members 32 that pivotally connect the first leg 25 to the third leg 33 and the second
leg 27 to the fourth leg 35. Thus, when in the use position where the second support
bar 36 is received by the one or more brackets 38 and no substantial rotation of the
second support bar 36 is permitted, the first pair of collapsible legs 26 are also
in a fixed position to provide a sturdily supported tabletop 12. However, when the
second support bar 36 is removed from the one or more brackets 38, the first pair
of collapsible legs 26 and the second pair of collapsible legs 34 are operable to
pivot relative to each other to move from the use position to a storage position.
In the storage position, the legs are preferably all positioned substantially perpendicular
to the ends 18 and 20 of the tabletop 12 (as best shown in FIGS. 9 - 10), and the
second support bar 36 is received within the bottom surface 16 of the tabletop 12
adjacent to the first end 18 and the first support bar 28 (as best shown in FIG. 10).
It is noted that, to permit the pivoting movement described above, the second support
bar 36 has a slightly smaller length than the first support bar 28. As a result, the
second pair of collapsible legs 34 fit between and are able to move within the space
of the first pair of collapsible legs 26.
[0015] In preferred embodiments where the legs of table 10 are longer than the distance
between the first end 20 and second end 22 of tabletop 12 as commonly occurs with
respect to tables having a smaller surface area such as bistro tables, the second
end 20 of tabletop 12 includes a first receiving channel 40 and a second receiving
channel 42. The first receiving channel 40 is positioned and configured for receiving
a portion of the first leg 25 and the third leg 33 in their respective collapsed positions.
The second receiving channel 42 is positioned and configured for receiving a top end
portion of the second leg 27 and fourth leg 35 in their respective collapsed positions.
For purposes of the present disclosure, the top end portions of the legs 25, 27, 33,
and 35 are the portions of the legs that are disposed beneath the bottom surface 16
of the tabletop 12 in the storage position. Together, the first and second receiving
channels 40 and 42 permit a more compact storage position by allowing the top end
portions of the legs 25, 27, 33, and 35 to be received directly beneath the bottom
surface 16 within the first end 18 and the second end 20 of the tabletop 12 with the
bottom end portions of the legs extending out from the receiving channels 40 and 42.
[0016] To provide further support to the collapsible table 10, a third support bar 44 is
preferably provided that, like the second support bar 36, secures the third leg 33
to the fourth leg 35. As shown best by comparing FIGS. 2 and 10, the third support
bar 44 is preferably positioned between the third leg 33 and fourth leg 35 such that
it can be removably secured in the storage position to the same brackets 38 used to
removably secure the second support bar 36 in the use position. In other words, the
third support bar 44 connects the second pair of collapsible legs 34 to the bottom
surface 16 of the tabletop 12 in the storage position via brackets 38 while the second
support bar 36 connects the second pair of collapsible legs 34 to the bottom surface
16 of the tabletop 12 in the use position via one or more of the same brackets 38.
Removably securing the third support bar 44 to the bottom surface 16 of the tabletop
12 provides a sturdier storage position in which the legs will only move when desired.
Further, by removably securing the third support bar 44 in the storage position to
the same brackets 38 used to secure the second support bar 36 in the use position,
a more efficiently molded tabletop 12 is provided with fewer molded parts.
[0017] The collapsible table 10 described above is believed to be best utilized with respect
to tabletops and related surfaces having a smaller sized surface area such bistro
tables, television trays, folding chairs, stools, etc. where the legs have a greater
length than the distance between opposing ends or sides of the surface supported by
the legs. Thus, while the present disclosure is described herein with respect to collapsible
table 10, it should be understood that the disclosure could also be utilized with
respect to other surfaces that are supported by collapsible legs such as a chair or
stool.
[0018] According to an alternative embodiment, the table is substantially as described above
except that the first leg 25 and second leg 27 are operable to be collapsed independently
of each other as known in the art. Thus, according to this embodiment, first support
bar 28 connecting the first leg 25 to the second leg 27 is not required, and the first
pair of collapsible legs 26 are not pivotally cross-connected to the second pair of
collapsible legs 34.
[0019] The foregoing description of preferred embodiments for this invention have been presented
for purposes of illustration and description. They are not intended to be exhaustive
or to limit the invention to the precise form disclosed. Obvious modifications or
variations are possible within the scope of the invention defined by the appended
