Field of the invention
[0001] The invention, in general, relates to a support structure, in particular to a modular
support structure for forming a rack or a shelf or a seat attachable to a wall. The
invention also relates to a method of mounting a rack or a shelf or a seat to a wall,
making use of such a support structure.
Background of the invention
[0002] FIG. 1 shows a typical prior art bookshelf. It comprises a wooden board 22 which
is placed on two or more metal brackets 21 (only one is shown), each of which is separately
attached to a wall, for example screwed thereon. The shown metal bracket 21 is composed
of three elements: a first elongated profile 23, a second elongated profile 24 which
is perpendicular thereto, and a triangular profile 25 which is perpendicular to both
profiles 23, 24. Typically, holes are drilled in the two elongated profiles, for attaching
the bracket 21 to a wall. The three elements 23, 24, 25 are typically welded together.
Two or more of such brackets 21 are attached to a wall, at a distance from each other,
it not being easy to place the two brackets at the same height, and a board 22 is
then placed on or attached to the brackets. There is a need for a support structure
that is easier to manufacture and/or easier to install.
Summary of the invention
[0003] It is an object of the present invention to provide a good support structure that
can be used, for example, for forming a seat or a shelf or a rack, or the like (for
example, a desktop).
[0004] It is also an object of the present invention to provide a good seat, a good shelf,
and a good rack, comprising such a support structure.
[0005] It is further an object of the present invention to provide a good method for mounting
such a support structure, seat, shelf or rack to a wall.
[0006] These objects are achieved by a support structure, a seat, a shelf, a rack, and a
method according to embodiments of the present invention.
[0007] In a first aspect of the present invention, a support structure is provided for forming
a shelf or a rack or a seat, or the like, said support structure comprising:
a U-shaped support profile with a middle wall and two side walls substantially perpendicular
to the middle wall, the middle wall having a plurality of first apertures for attaching
the support profile to a wall, the two side walls being located at a first distance
(H) from one another, and at least one of the side walls, in particular, at least
the side wall, having a plurality of pairs of second apertures for attaching support
arms;
at least two support arms, each support arm having dimensions such that the support
arm is mountable between the two side walls of the support profile in a direction
perpendicular to the longitudinal direction (Y) of the support profile, each support
arm having a pair of projections that fit into a pair of second apertures in a side
wall of the support profile, each support arm having a planar surface on which a planar
object can be placed.
It is an advantage of embodiments of the present invention that the support profile
is U-shaped, because on the one hand it ensures great strength and on the other hand
it allows the support arm to be placed in between it.
It is an advantage that one of the two side walls of the support profile (i.e., the
top side wall, after placement) has a pair of second apertures, so that the support
profile can receive projections of the support arm, which act as a hinge when mounting
the support arm, and after mounting act to absorb the moment of forces exerted by
and on the support arm.
[0008] Although not necessary, it is a clear advantage that the other side wall (the bottom
side wall, after placement) of the support profile also has pairs of second apertures,
because it allows small protuberances to snap into said pairs of second apertures.
[0009] A person skilled in the art can choose the dimensions of both the support profile
and of the support arm (for example, height, length, width, and particularly the thickness),
such that the anticipated load (for example, a wood covering and books) can be borne,
and that the support arm fits precisely between the side walls of the support profile.
[0010] It is an advantage that the support arm is placed between the side walls of the support
profile, so that the support arm can rest on the bottom side wall.
[0011] It is an advantage of the means of attachment with apertures and with projections,
sometimes also referred to as 'lugs' or 'pins', that no screws or other means are
necessary (for example, welding) to secure the support arms to the support profile.
It is to be noticed that the adjusting screw does not serve to fix the support arm
to the support profile, but to bring the support arm to a desired angle. It is an
advantage that the fixing can be done in a very simple way, namely by tilting.
[0012] It is an advantage that the support arm is mounted between the two side walls of
the support profile, so that it cannot fall out by itself.
[0013] It is an advantage of this mounting structure, in particular of its suspension arrangement,
that 'legs' or triangular profiles or other supports are not needed, and preferably
none are used, under the support arms, in order to support them. This allows for a
sleek and elegant looking solution. Such a bookshelf is also called a 'floating shelf'
or 'floating bookshelf', or a board (or rack or seat) with hidden suspension or a
board with a blind attachment.
[0014] It is an advantage of this support structure that it allows for modular construction.
The end user can select all the components themselves, for example, the amount of
support arms, and/or support arms with a specific length, depending on the application,
for example, of the load which the support structure has to bear. If the load to be
borne is too large, the end user can provide, for example, multiple support arms.
If the covering (for example, a bookshelf) is long, the end user may, for example,
mount multiple support profiles contiguously against each other. In order to easily
mount support profiles contiguously in the longitudinal direction, co-acting connecting
means should preferably be provided, such as a tongue and groove connection.
[0015] The projections may be carried out unitarily with the material of the support arm,
so that the likelihood of folds or separation or deformation is minimal.
[0016] Optionally, the support arm may have apertures in the planar surface, for securing,
for example, a shelf, for example, by screwing, although this is not strictly necessary,
a glass plate; for example, can be simply placed on the planar surface, possibly with
a felt strip, or the like, between the support arm and the glass.
[0017] The planar object which can be placed on the planar surface could be a shelf or a
covering of a seat, or the like. It could also be a desktop. The planar object is
preferably slid over the support structure, so that the entire support structure (both
support profile and support arms) are no longer visible, and the whole looks very
smooth and elegant.
[0018] In embodiments of the present invention, a support structure as described above is
provided, each support arm comprising a U-shaped profile.
[0019] It is an advantage of this embodiment if the support arm also mainly consists of
a U-section, because such a support arm, on the one hand, has the necessary strength
to resist the bending forces, and, on the other hand, can be made relatively easily
and inexpensively. In an example, the support arm consists substantially of a U-shaped
profile with only a few small parts such as the projections, and/or a screw holder
for an adjusting screw, and/or a bent back side, or the like.
[0020] On the other hand, the invention could also work if the support arm were to consist
largely of a square or rectangular tube, albeit with a cut-out at the height of the
adjusting screw (if present). A U-profile offers the advantage over the tube shape
that it requires less material, and that the cut-out for the adjusting screw (if present)
may be omitted.
[0021] There is further provided in embodiments of the present invention a support structure,
the support profile and the support arms being made of metal.
[0022] In some embodiments, the support profile and the support arm can be made of metal,
for example of steel, as it provides the desired strength on the one hand, and on
the other hand can be formed easily.
[0023] In an embodiment, a support structure is provided, the support profile and the support
arms being made of stainless steel.
[0024] Such embodiments have the advantage that they cannot rust. They are especially useful
for applications in damp places, such as in or next to a swimming pool, outdoor applications,
or other damp areas such as a bathroom or a laundry room.
[0025] Subsequently, a support structure is provided, as described above, the support profile
and the support arms being made by punching and bending of metal.
[0026] It is an advantage of punching that apertures may be provided in a way that is much
faster than drilling, and that the apertures may be not only circular, but also, for
example, may be elongated.
[0027] In some embodiments, rounded U-profiles can be used in place of U-profiles with a
full right angle, since the latter exhibit a relatively sharp edge, and require more
material. By bending, sharp corners can therefore be avoided, as well as material
saved. In addition, bending is a common, quick and simple production technique.
[0028] In an embodiment of the present invention a support structure is obtained, at least
one support arm having at least one aperture in one of the side walls.
[0029] In an embodiment, each support arm has at least one aperture in one of the side walls.
Each support arm can have one or more apertures in both side walls.
[0030] 'Side walls' here means the walls that are perpendicular to the planar surface upon
which, for example, a shelf is to be placed, i.e., the upright or vertical walls when
the support arm is mounted. It is an advantage of such (an) aperture(s) that the support
arm can, for example, be attached to a side wall. It is an advantage that in certain
applications (e.g. a seat) this (these) aperture(s) may also be used for attaching,
for example, a 'leg'. It is further an advantage in certain applications (for example,
a rack), that these apertures can be used for attaching partitions, for example, upright
boards in the case of multiple shelves above each other, for creating compartments
between the individual boards.
[0031] In some embodiments, each support arm of the support structure has an adjusting screw
allowing an angle between the support profile and the support arm to be set.
[0032] It is an advantage of certain embodiments of the present invention that an adjusting
screw is provided to allow an angle to be adjusted between the support profile and
the support arm (albeit to a limited extent, for example in the range of -5° to +5°),
and this in a continuous manner (i.e. without discrete steps). In this way, all support
arms can, for example, be placed exactly level, so that the covering (for example,
wooden board or glass plate) that is placed or slid on it is more uniformly supported,
and so that the risk of bursting or deformation is minimal. Also in case of an inclined
wall or wall, for example, a wall that is not entirely perpendicular to the ground
surface and which, for example, deflects towards the inner side, all support arms
can be placed level with the aid of the adjusting screw. By placing sufficient support
arms, in most cases, deflection of, for example, long boards is avoided. If some deflection
should still occur, the angle between the support profile and the support arm can
be adjusted with the aid of an adjusting screw, in an attempt to remedy or minimise
the deflection.
[0033] In an embodiment of the present invention, a support structure is provided wherein
both of the side walls of the support profile have pairs of second apertures, which
are situated opposite each other, each support arm further having a pair of protuberances,
which can be inserted into the pair of second apertures in the side wall.
[0034] It is an advantage of these protuberances that the support arm can snap into place
in this way, so that the support arm is not only resting, but that a minimal force
has to be overcome in order to snap off the support arm again by tilting it upwards.
In this way, the support arm can be prevented from tilting upwards by mistake and
snapping off. The minimal force which must be overcome can be easily determined by
a person skilled in the art, by an appropriate selection of the protuberances (e.g.,
by an appropriate selection of a pin with a bevelled edge with an appropriate angle
and dimensions). Alternatively, instead of protuberances, projections can be provided
here too, for example, such as the projections that fit in the top side wall of the
support profile. The latter can be of interest for applications where it is desired
that the support arms be very hard to detach, or even not at all, except with additional
aids in order to push the two side walls of the support profile away from each other.
[0035] With the aid of the support structure described above, a seat, or a shelf, or a rack,
or a desktop, can be obtained after applying a planar object over or on the support
structure.
[0036] In one aspect, the present invention relates to a seat comprising the support structure
described above, further including a covering, applied to the least two support arms.
[0037] The covering of a seat is preferably substantially flat.
[0038] The substantially planar covering may, for example, be a thick wooden plank, for
example, 8 cm thick, possibly having a wavy top surface as is typical for seats, in
order to better match the shape of a seat surface. Said covering may be simply placed
loosely on the support arms, or glued to it, or screwed to it (if the planar surface
has the necessary apertures for this purpose). The covering is preferably slid over
the support structure (support arms and support profile) so that the support structure
is no longer visible.
[0039] Further, a shelf is also described, which comprises the support structure described
above, and a shelf or plate applied to the at least two support arms.
[0040] The plate or panel may, for example, be a planar wooden or planar metal or planar
glass plate. However, it could also be a bent metal plate, for example, in an L shape
or Z shape, with a raised edge in order to prevent deflection, and/or to affix, for
example, labels, and/or to create a partition with the back wall (e.g., the wall).
[0041] Still further, a rack is also described, which comprises at least two shelves as
described above. In addition, a rack is also described, further comprising at least
one upright board or plate, which is placed between the board of the top shelf and
the board of the bottom shelf, and which is attached to a side wall (9) of one of
the support arms of the top shelf.
[0042] In a further aspect, a kit of parts for assembling a support structure is also provided
which comprises at least one support profile described above, and at least two support
arms described above.
[0043] A number of methods for mounting a support structure are also provided.
[0044] A method is provided for mounting a support structure described above to a wall,
the method comprising the steps of:
- a) attaching the U-shaped support profile to a wall, such that the support profile
is substantially horizontally oriented, having its middle wall attached to the wall,
and such that the two side walls are oriented substantially perpendicular to the wall
and that the side wall with the pairs of second apertures is located at the top;
- b) orienting a first, respectively second support arm substantially perpendicular
to the wall, and positioning the first, respectively second support arm between the
two side walls of the support profile, and inserting the two projections of the first,
respectively second support arm in a first, respectively second pair of second apertures
in the side wall of the support profile which is located at the top, by tilting the
first, respectively second support arm, subsequently inserting the projections into
the second apertures of the top side wall, and then tilting the first, respectively
second support arm so that it is substantially perpendicular to the support profile.
[0045] It is an advantage of this method that it can be very easily performed, and that
no specialised personnel and/or equipment (for example, welding equipment) is needed.
It is noted that the wall can be either an unfinished wall (for example, if the support
profile is incorporated into the plaster), or a finished wall (for example, surface-mounting).
If the support profile is built in to the wall (flush mounting), then this also provides
additional stability and anchoring in the wall. In addition, flush mounting also has
the advantage that the support arms can be removed when, for example, painting or
wallpapering or when applying membrane to a wall, in order to facilitate this work.
Both in cases of flush mounting and surface mounting, when working with a planar object
which is slid over the support structure, the support structure is no longer visible
after applying the planar object.
[0046] A method is also provided for mounting a seat to a wall, comprising:
mounting a support structure to a wall as described above,
applying a covering to a first and a second support arm.
[0047] The covering, for example a board, may be simply placed loosely on it, or glued to
it, or screwed to it, or attached in some other way.
[0048] In addition, a method for mounting a shelf to a wall is also provided, comprising:
mounting a support structure to a wall as described above,
applying a board to a first and a second support arm.
[0049] The board may be simply placed loosely on it, or glued to it, or screwed to it, or
attached in some other way.
[0050] In addition, a method is also provided for mounting a rack with at least two shelves
to a wall, comprising:
mounting a first shelf to a wall as described above,
mounting a second shelf to a wall also as described above, substantially parallel
to a first shelf.
[0051] Particular and preferred aspects of the invention are set out in the appended independent
and dependent claims. Features from the dependent claims may be combined with features
of the independent claims and with features of other dependent claims as appropriate
and not merely as explicitly set out in the claims.
[0052] For purposes of summarising the invention and the advantages achieved over the prior
art, certain objects and advantages of the invention have been described herein above.
Of course, it is to be understood that not necessarily all such objects or advantages
may be achieved according to any particular embodiment of the invention. Consequently,
persons who are skilled in this matter, will, for example, recognise that the invention
may be embodied or carried out in a way that achieves one advantage or a group of
advantages as described herein, without necessarily achieving other objects or advantages
that are described or suggested herein.
[0053] The above and other aspects of the invention will be apparent from and elucidated
with reference to the embodiment(s) described hereinafter.

[0055] The drawings are only schematic and are non-limiting. In the drawings, the size of
some of the elements may be exaggerated and not drawn to scale for illustrative purposes.
The dimensions and the relative dimensions do not necessarily correspond to actual
reductions to practice of the invention.
[0056] Any reference signs in the claims shall not be construed as limiting the scope.
[0057] In the different drawings, the same reference signs refer to the same or analogous
elements.
Detailed description of embodiments of the invention
[0058] The present invention will be described with reference to particular embodiments
and with reference to particular drawings, but the invention is not limited thereto
and is limited only by the claims.
[0059] It is to be noticed that the term 'comprising', used in the claims, should not be
interpreted as being restricted to the means listed thereafter; it does not exclude
other elements or steps. It is thus to be interpreted as specifying the presence of
the stated features, integers, steps or components as referred to, but does not preclude
the presence or addition of one or more other features, integers, steps or components,
or groups thereof. Thus, the scope of the expression 'a device comprising means A
and B' should not be limited to devices consisting only of components A and B. It
means that with respect to the present invention, the only relevant components of
the device are A and B.
[0060] Reference throughout this specification to 'one embodiment' or 'an embodiment' means
that a particular feature, structure or characteristic described in connection with
the embodiment is included in at least one embodiment of the present invention. Thus,
appearances of the phrases 'in one embodiment' or 'in an embodiment' in various places
throughout this specification may, but do not necessarily, all refer to the same embodiment.
Furthermore, the particular features, structures or characteristics may be combined
in any suitable manner, as would be apparent to one of ordinary skill in the art from
this disclosure, in one or more embodiments.
[0061] Similarly, it should be appreciated that in the description of exemplary embodiments
of the invention, various features of the invention are sometimes grouped together
in a single embodiment, figure, or description thereof for the purpose of streamlining
the disclosure and aiding in the understanding of one or more of the various inventive
aspects. This method of disclosure, however, is not to be interpreted as reflecting
an intention that the claimed invention requires more features than are expressly
recited in each claim. The claims following the detailed description are hereby expressly
incorporated into this detailed description, with each claim standing on its own as
a separate embodiment of this invention.
[0062] Furthermore, while some embodiments described herein include some but not other features
included in other embodiments, combinations of features of different embodiments are
meant to be within the scope of the invention, and form different embodiments, as
would be understood by those in the art. For example, in the following claims, any
of the claimed embodiments can be used in any combination.
[0063] In the description provided herein, numerous specific details are set forth. However,
it is understood that embodiments of the invention may be practised without these
specific details. In other instances, well-known methods, structures and techniques
have not been shown in detail in order not to obscure an understanding of this description.
[0064] FIG. 1 shows a prior art bookshelf. It comprises at least two brackets 21 (only one
of them is shown), and a wooden board 22.
[0065] FIG. 2(a) shows a support structure 1 according to an embodiment of the present invention.
The shown support structure 1 is composed of three support profiles 2a, 2b, 2c that
can be attached to a wall (as will be explained below), to which four support arms
10a, 10b, 10c and 10d are attached (as will be explained below). FIG. 2(b) is a variant
of FIG. 2(a) and shows another embodiment of a support structure 1 according to the
present invention. This support structure 1 consists of two support profiles 2 that
can be attached to a wall, to which three support arms 10 are attached. FIG. 2(c)
shows a second variant of FIG. 2(a), consisting of a single support profile 2 that
can be attached to a wall, and to which two support arms 10 are attached. It is to
be noticed that these are only examples of the invention, and that, for example, a
support structure such as that of FIG. 2(a) with only a single support profile 2 and
with four support arms 10, is also part of the invention.
[0066] FIG. 3 shows in more detail an example of a support profile 2, such as may be used
in the support structure of FIG. 2 (a) to FIG. 2(c), in perspective view. The shown
support profile 2 consists of a U-shaped profile with a middle wall 3, here shown
upright, as this middle wall is generally attached to an upright wall or the like,
for example, making use of the apertures 5. This attaching can be done in known ways,
for example by drilling holes in the wall, providing containers or plugs in those
holes, and then attaching the support profile with a screw or bolt, but other ways
are also possible.
[0067] The support profile 2 is typically placed level, so that the top side wall 4a and
the bottom side wall 4b are horizontal. In the top side wall 4a (and preferably also
in the bottom side wall 4b, although this is not strictly necessary) pairs of second
apertures 7 are provided, which are located at a predetermined distance 'd' from one
another. As will be explained further, these apertures 7 serve to receive projections
12 of support arms 10. In the example of FIG. 3 only a few pairs 7 are shown, but
the number may of course be much more.
[0068] This support profile 2 can, for example, be manufactured by perforating (punching)
steel plate of the desired thickness, cutting it, and then bending it. Punching has
the advantage (vis-à-vis drilling) that it is a faster technique, and that the apertures
5 need not necessarily have a circular cross-section, as well as it not being necessary
to remove burrs.
[0069] FIG. 4 shows the support profile 2 of FIG. 3 in front view, with the difference that
the profile of FIG. 4 also has connecting means 6, such as a protruding element (on
the left) that fits into a complementary cavity (on the right), also known as a 'tongue
and groove' connection. Such connection elements 6 are especially interesting when
multiple support profiles 2 have to be placed abutting each other to form one long
support profile, but are not strictly necessary. The support profile shown in FIG.
4 can be used, for example, in position 2b of FIG. 2. Between the two walls a distance
'H' is available (why this is the case will be made clear below).
[0070] FIG. 5 to FIG. 7 show various views of a preferred embodiment of a support arm 10,
as may be used in the support structure 1 of FIG. 2. The support arm 10 comprises
a substantially U-shaped profile. It includes a planar surface 13 (in FIG. 5, shown
at the top, such as the support arm is mounted in practice), to which a board or covering
or the like (not shown) may be applied, for example, by simply placing it on it, or
gluing it on it, or screwing it on it, etc. In the latter case, at least one aperture
is provided in the surface 13 (not shown).
[0071] The support arm 10 further comprises two upright side walls 9, which are perpendicular
to the surface 13, which provide stiffness and the necessary strength to the support
arm. In these side walls 9, apertures 14, for example, may be provided, to optionally
laterally connect the support arm with a partition, for example a wall, if desired.
However, these apertures 14 may also be used to provide, for example, upright partition
elements (for example, upright separation boards), if the support structure 1 is used
as, for example, a bookshelf. The corners 16 may be rounded or bevelled, in order
to reduce the risk of injuries.
[0072] The support arm 10 further comprises two projections 12, at a distance 'd' from each
other. This is the same distance as the distance between the second apertures 7 of
the support profile (see FIG. 3). These projections are sometimes also referred to
as 'lugs' or 'pins'. The shape and dimensions of the projections 12 of the support
arm 10 is so selected that they can be inserted into the apertures 7 of the support
profile 2. Said insertion is further facilitated by the inclined wall 15 of the support
arm. The height 'H' of the support arm 10 (see FIG. 7) is selected so that it fits
between the two side walls 4a, 4b of the support profile 2 (see FIG. 8 to FIG. 10).
During insertion of the support arm 10 between the side walls 4 of the support profile
2, the two projections 12 serve as pivot points, as described in FIG. 8. After insertion
of the support arm 10 between the side faces 4 of the support profile 2, the projections
12 serve to bear the moment of flexure of the weight of the support arm 10 itself,
and the load which is applied to the support arm 10, for example, in the case of a
seat, the weight of the board, and of the person(s) sitting on the seat.
[0073] The support arm 10 can also include two bulges or protuberances 19 at the bottom,
located opposite the projections 12. If the bottom side wall 4b of the support profile
2 also has second apertures 7, these protuberances 19 can engage therein (after the
tilt). In this way, the support arm can be snapped in place. By giving these protuberances
19 a suitable form, it can be ensured that the support arm 10 can be snapped off again
with a relatively small upward force.
[0074] The support arm 10 can optionally also have and adjusting screw 18, and, if necessary,
a screw holder 17 with internal screw thread holding this adjusting screw 18, the
screw holder 17 opening into an aperture 11, all positioned in such a way that the
adjusting screw 18 is provided to press against the middle wall 3 of the support profile
2 when the support arm 10 is inserted between the side walls 4 of the support profile
2. This is shown schematically in FIG. 8 (although the support arm is here not yet
tilted). In an embodiment, the support profile 2 and the support arm 10 can have such
dimensions that a tilt through an angle range from -5° to +5° with respect to the
normal position perpendicular to the middle wall 3, can be adjusted by the adjusting
screw 18. The adjusting screw 18 may be an Allen screw.
[0075] FIG. 6 shows the support arm 10 of FIG. 5 as viewed from point VI. Herein, the planar
surface 13, the flattened or bevelled edge 15, the projections 12, and the aperture
11 for the adjusting screw 18, are clearly visible.
[0076] FIG. 7 shows the support arm 10 of FIG. 5 as viewed from point VII (from below).
Herein, the screw holder 17, and the adjusting screw 18 are clearly visible. It is
noted that the support arm 10 is here drawn upside down, so that the protuberances
19 are now located at the top, and the projections 12 at the bottom, for illustrative
purposes.
[0077] FIG. 8 shows how the support arm 10 can be mounted in the support profile 2. In a
first movement '(1)', the support arm 10 is positioned as shown, and the projections
12 of the support arm 10 are inserted into the second apertures 7 of the top side
wall 4a of the support profile 2. Next, the support arm 10 is tilted in a second movement
'(2)', the projections 12 acting as pivot points, so that the support arm 10 is positioned
substantially horizontally, and rests on the bottom side wall 4b. Possibly (but not
necessarily), the protuberances 19 (if present) engage the second apertures 7 of the
bottom side wall 4b. Possibly (but not necessarily), an adjusting screw 18 is present,
which can now be adjusted in order to level the planar surface 13.
[0078] FIG. 9 shows the support arm 10 during the snapping-in of the support arm 10 into
the support profile 2 (seen from above).
[0079] FIG. 10 shows the support arm 10, after the snapping-in of the support arm 10 into
the support profile 2 (seen from below), from point X in FIG. 9.
[0080] With the support structure 1 as described above, it is thus possible to easily and
correctly mount seats or boards to different types of walls by means of the support
structure (in modular construction), or a kit of parts for assembling a support structure,
both surface mounted (after finishing of the walls) and flush mounted (before finishing
of the walls). Ideally, with both flush mounting and surface mounting, the support
structure is completely hidden after applying a board or seat.
[0081] The maximum load is mainly determined by the material thickness of both the support
profile 2 and of the support arms 10, and by the height 'H' (distance between the
two side walls 4a, 4b of the support profile 2). The thicker the material thickness,
and the greater the height 'H', the larger the carrying capacity. Of course, the anchorage
to or in the wall is of crucial importance in case there is a large load.
[0082] Although in the drawings shown only a few apertures (first apertures 5 and/or two
apertures 7) are provided in the support profile 2, it will be appreciated that repetitive
perforations over the entire length of the support profile is possible.
[0083] The dimensions of the support arms 10 are dependent on the intended dimensions of
the seat or of the rack or of the shelves. They can be produced in different sizes.
While particular embodiments have been discussed above, changes can thus be made.
For example, the rear face can be reduced. The side walls 9 may be placed closer together.
Under the adjusting screw 18, an additional plane may also be provided which comes
back to the front, at an angle of 90° to the rear vertical plane in which the adjusting
screw is positioned. This rear face ends up under the bevelled edge 15.
[0084] The support structure 1 as described above is suitable for both surface mounting
and flush mounting. The support profile 2 can be placed in advance (i.e. before finishing,
such as plastering); after finishing of the wall the support arms and the seat itself
are mounted in it. The support profile 2 for flush mounting can be applied such that
it is suitable for plastering, dry-wall installation, tiling or other forms of wall
finishing. From an aesthetic point of view, flush mounting is preferable.
[0085] The support structure 1 as described above offers the following advantages, among
others:
(1) Economic and ecological:
[0086] There is a modular construction: no finished goods need to be transported.
[0087] Preferably, the support arm 10 is manufactured from a single piece of metal plate.
Because of this, no additional operations are required to join different parts together.
[0088] It can be manufactured out of standard steel plate and components that are easily
available everywhere.
[0089] It can be produced through simple production techniques using standard metalworking
machinery.
(2) Simple placement:
[0090] The support arms 10 easily snap into the apertures 7 in the support profile 2 provided
to this end. Once they are snapped in, the support arms 10 can, if desired, be snapped
back out with a simple click.
[0091] Optionally, the support structure is provided with an adjusting screw 18 to make
the slope of the support arms 10 horizontal steplessly.
[0092] If the seat is placed in a corner, the support arm 10 may be laterally fixed with
a screw (apertures 14 are provided in the side of a support arm 10 for this purpose).
[0093] One basic set and one or more extension kits can be endlessly combined to achieve
the desired length.
[0094] There is a logical structure, which allows any person skilled in the art to place
this support structure 1, without any need for special equipment (for example, welding
equipment).
[0095] It can be used for different thicknesses (the thickness profile can be chosen).
[0096] It can be placed in both surface mounted and flush mounted applications.
[0097] The support profile 2 can be placed first, without the support arms 10. The support
arms 10 can be placed afterwards. As a result, there is no disturbance in the building,
up to the time of finishing.
[0098] It can be used anywhere on a firm, flat surface (walls, partitions, etc.).
(3) Aesthetic:
[0099] Shelves are mounted invisibly.
[0100] This makes a minimalist and sleek look possible (mounted fully flush).
[0101] The finish of the covering is independent of support arms 10 and support profile
2.
[0102] The structure can easily be provided with extras such as apertures, lighting, or
electrical outlets.
[0103] The support structure 1 as described above can be used, for example, for the following
applications: shelves; bookshelves; dressers; racks (for example at home or in a shop),
horizontal distributions; desktops; shelves in bathrooms, shops, showrooms, libraries;
optional in stainless steel version for applications in wet areas such as swimming
pools, catering, food, bathrooms, saunas; benches in public places such as banks,
libraries, schools, sports halls, and museums.
[0104] The structure is suitable for indoor and outdoor furniture.
