[0001] The present invention relates to a support for articles of furniture, for instance
tables, cupboards, sofas, wall furniture and the like.
[0002] For furnishing a space in a house or a public space such as museums, theatres, hotel
lobbies and office buildings there is a need for furniture whose arrangement can be
changed quickly and easily. By adjusting the arrangement of the furniture the space
is given a different atmosphere, and the functionality can also be modified.
[0003] Known from DE 88 09 657 U is a support consisting of a tabletop and a table leg on
which two rotatable support parts are mounted. In the non-folded out situation the
two support parts form a unit with the table top. In the folded-out situation the
support parts are rotated relative to each other such that two tabletops can rest
on the table leg. One of the two tabletops is however only a tabletop (Einhängeplatte)
which is placed on a support part when necessary. The sheet cannot stand independently
and must always be arranged between two successively placed supports.
[0004] Known from DE 298 08 054 is a system in which, on a central table leg, a first tabletop
is arranged at seating height and a second tabletop is arranged at standing height.
The known system however requires an anchoring of the central table leg in the ground
to be able to produce a stable support.
[0005] The present invention has for its object to provide a support for an article of furniture,
whereby the functionality of the article of furniture can be modified quickly and
easily.
[0006] In order to achieve this object there is provided a support of an article of furniture,
which support comprises:
- a first frame provided with a first and a second support leg for supporting the frame
on a ground surface, wherein the first frame is suitable for bearing a first article
of furniture;
- a second frame provided with a first and a second support leg for supporting the frame
on the ground surface, wherein the second frame is suitable for bearing a second article
of furniture;
- a shared pivoting support leg which can be placed on the ground surface and comprises
at least a first support leg part to which the first frame is fixed, as well as a
second support leg part to which the second frame is fixed;
wherein the support leg parts take a pivotal form for the purpose of pivoting at least
one of the frames relative to the ground surface and/or the other frame.
[0007] The first frame supports on two legs and on the pivoting support leg, while the second
frame likewise rests on two support legs and on the same shared pivoting support leg.
The shared pivoting support leg not only serves as support for both frames, but also
as point of rotation along which the frames can be rotated in random direction relative
to the ground surface.
[0008] According to a preferred embodiment, the frames take an elongate form and a pivoting
support leg is embodied for the purpose of pivoting frames between a folded-in position,
in which the long sides of the first and second frame run substantially parallel,
and a folded-out position, in which the short sides of the first and second frame
run substantially parallel. In said first position, also referred to as the closed
position, the long sides of the frames are mutually adjacent. Because the articles
of furniture now stand with their long sides toward each other, they form a more or
less closed surface. In the case the frames form a rectangle, the two frames form
a rectangle of relatively large dimensions around which the users can walk. In the
completely folded-open position, in which the frames are rotated through about 180',
the short sides of the frames are mutually adjacent. The articles of furniture then
stand with the short sides against each other and form an elongate whole which can
for instance be readily placed against a wall. It will be apparent that diverse intermediate
positions are also possible. It is thus possible for instance to rotate the frames
at an angle of about 90° relative to each other so that the articles of furniture
can for instance be placed around a corner of the space. A further advantage of placing
in such a position is that each of the frames can have a separate function. A first
frame with tabletop is for instance used as workplace, while the second frame with
tabletop is used as a dining table.
[0009] Changing the disposition of the pieces of furniture is very simple and requires little
effort. The shared central support leg ensures that the articles of furniture can
be readily rotated to any desired position. In all positions the support legs give
the frames sufficient support so that a substantially stable assembly is provided.
[0010] According to a further preferred embodiment, the pivoting support leg is provided
with locking means so that the chosen position of the frames can be fixed.
[0011] In a further preferred embodiment, the support legs provide length-adjusting means
for adjusting the length of the relevant leg in order to set the height of the furniture
parts above the ground surface. Support is hereby guaranteed and the articles of furniture
also stand straight and stable on an uneven floor.
[0012] In a first embodiment of the shared support leg, both the first and the second support
leg part are embodied for rotation relative to the remaining part of the support leg,
so that when the remaining part of the support leg is placed on a ground surface,
both the first and the second frame can be rotated relative to the stationary part
of the support leg. In other embodiments only one of the two support leg parts is
rotatable relative to the remaining part of the shared support leg, so that only one
of the frames is pivotable relative to the other frame and the ground surface.
[0013] In order to increase the options of use of the pivotable support as much as possible,
the pivoting support leg is preferably mounted close to both peripheral edges of the
first frame, or even close to the corner point hereof. When the support leg is arranged
in the corner point of the first frame as well as in the corner point of the second
frame, this ensures a maximally pivotable assembly.
[0014] In a further preferred embodiment, a locking element is provided for locking the
frames in folded-in position and in folded-out position. This locking element can
take on the form of a separate component, for instance a bracket, with which engagement
can be made with the edges of the first and the second frame situated opposite the
pivoting support leg. The user can hereby fix both frames relative to each other in
rapid and simple manner by having the bracket engage on the first and second frame.
[0015] As already stated above, in another embodiment the shared support leg is itself provided
with locking means. With these locking means the frames can not only be fixed relative
to each other in folded-in position but also in the folded-out position in all intermediate
positions between the completely folded-out and completely folded-in position.
[0016] In a further embodiment, the central support leg of the support comprises:
- a first support leg part which is provided with a fastening element for fastening
the first frame and with a cylindrical protrusion;
- a second support leg part which is provided with a fastening element for fastening
the second frame and with an elongate element which is provided internally with a
tubular receiving element in which the protrusion of the first support leg part can
be received in freely rotatable manner.
[0017] In this manner the pivoting connection between the frame elements can be effected
in simple manner. In other embodiments lubrication, one or more intermediate rings
and/or bearings can be applied between the first support leg part and the second support
leg part to further improve the rotation capability.
[0018] The frames are herein preferably fixed to the respective first and second support
leg parts via fixing elements such that the frames extend at substantially the same
height. When the frames serve for instance to support tabletops, a flat table can
be provided wherein the different table parts are pivotable relative to each other
between different positions. A flat table with different possible table configurations
is hereby provided.
[0019] In the above described embodiment the frames are used to bear tabletops of equal
height. It is however also possible to envisage placing the first frame at a lower
height than the second frame, so that first frame can be pushed at least partly under
the second frame. This ensures that the support takes up less space, for instance
for the purpose of storage thereof. It is noted that in some cases it is necessary
to remove the first and/or second support legs from the frame to enable rotation of
the first frame completely under the second frame. For this purpose the support legs
can be fixed releasably or removably to the frame in a manner known to the skilled
person.
[0020] According to a further preferred embodiment, the support is embodied for stable arrangement
on the ground surface with an unanchored, shared support leg. Since no anchoring,
for instance an anchoring in the ground surface, is necessary in this embodiment,
the unit of the support and pieces of furniture always remains freely displaceable
in the space. Furthermore, no special measures need to be taken in the ground surface,
whereby the ground surface, and thereby the appearance of the ground surface, can
remain unaffected. A possibility is provided for this purpose if the shared support
leg has a substantially flat underside for stable placing thereof on the ground surface.
[0021] According to a further preferred embodiment, the frames are arranged permanently
on the shared support leg and in the fixed situation the frames are pivotable in step-free
manner between extreme positions. The frames can herewith be folded in and folded
out without releasing the frames in any way whatsoever from the central support leg.
[0022] According to a further preferred embodiment, each of the frames comprises a stop
part, for instance a longitudinal edge of a rectangular frame, for limiting the pivoting
movement of the frames relative to the support leg. In this embodiment it is the shapes
of the frames which define the extreme positions of the support.
[0023] The invention also relates to the use of the support.
[0024] Further advantages, features and details of the present invention will be elucidated
on the basis of the following description of a preferred embodiment thereof. In the
description reference is made to the figures, in which:
figure 1 shows a perspective view of an embodiment of the invention in completely
folded-out situation;
figure 2 shows a perspective view of the preferred embodiment of figure 1 in an intermediate
position;
figure 3 shows a perspective view of the preferred embodiment of figure 1 in completely
folded-in situation;
figure 4 is a perspective view of a preferred embodiment of the shared support leg;
figure 5 is an exploded view of a part of the shared support leg; and
figure 6 shows a perspective view of a locking element.
[0025] Figure 1 shows a preferred embodiment of a support 1 which is suitable for supporting
tabletops, bookcases and so on. Support 1 is constructed from a left-hand frame 2
and a right-hand frame 3, wherein both frames 2 and 3 are fixed to each other using
a shared leg 9. The central leg 9 engages on a corner point of left-hand frame 2 and
on a corresponding corner point of right-hand frame 3. Both the left and right-hand
frame 2,3 are further provided with a number of support legs, viz. support legs 6
and 7 arranged respectively on the left and right-hand frame 2,3, this at the respective
corner points thereof which are situated opposite that corner point where the shared
support leg 9 engages. The first and the second frame 2,3 are further provided with
support legs 4,5. Support leg 4 is arranged on the edge of left-hand frame 2, this
being the edge lying opposite the edge extending between the above stated corner points.
The right-hand frame 3 is likewise provided with a support leg 5. Each of the support
legs is provided with a round cap 8, whereby the support legs can slide easily over
many types of ground surface. Other solutions can however also be envisaged. The support
legs can thus for instance be provided with swivel wheels.
[0026] Figures 4 and 5 show the construction of the shared support leg 9 in more detail.
The shared support leg allows folding-in and folding-out of frames 2,3. In the shown
embodiment the shared support leg 9 consists of two parts, viz. a lower part 15 and
an upper part 10. Both parts 15,10 are fastened to the associated frame 2,3 in known
manner, for instance using a nut and bolt connection, by means of respective mounting
plates 11 and 13. In the shown embodiment mounting plate 11 is connected to the right-hand
frame, while mounting plate 13 is connected to left-hand frame 2. The two said parts
15,10 of the shared support leg 9 rotate over each other substantially independently
of each other in the horizontal plane.
[0027] An inner tube 20 is inserted and welded fixedly into the upper part 10 of the shared
support leg 9, which tube 20 has a length of about twice the length of upper part
10. The tube of which the shared support leg 9 is made has an inner diameter which
is substantially the same as the outer diameter of inner tube 20. This entity of tubes
is then inserted into lower part 15. Inner tube 20 is not welded into lower part 15
of the support leg. Owing to these overlapping tubes in the tube construction the
two parts 10,15 of the shared support leg 9 can rotate separately of each other in
the horizontal plane. Due to its length and cross-section the inner tube 20 provides
both the pivot point and stability in the shared support leg 9. The shown construction
makes it possible to uncouple the first frame from the second frame rapidly and easily
when the support is not in use. The second frame remains standing, while the first
frame is placed upside down on the second frame, so that the support takes up relatively
little storage space. When the support is in use, the frame parts can remain permanently
arranged on each other, also during the adjustment of the position of the one frame
relative to the other frame.
[0028] As set forth above, figure 3 shows the situation in which the long sides of frames
2,3 are mutually adjacent. In this position the long sides of the frames form stop
surfaces which limit the pivoting movement of the frames. Because the frames lie closely
against each other in the shown embodiment (which in no way has to be the case in
other embodiments), a monolithic appearance can as it were be achieved. When the top
sides of the frames (or optionally the top side of tabletops or the like arranged
on the frames) extend at the same height, a flat top side of the construction can
be realized.
[0029] In the situation shown in figure 3 the articles of furniture stand with their backs
side by side and more or less form a square so that it is possible to walk round the
article of furniture. In the position shown in figure 1, frames 2,3 are rotated through
180° until the short side of the two frames 2,3 lie mutually adjacent. The articles
of furniture now stand with their short sides abutting, whereby an elongate assembly
is obtained. This assembly can for instance be placed against a wall. Because in this
position the frames also lie closely against each other, the monolithic character
can be preserved. A wholly flat (i.e. (practically) uninterrupted) top side of the
construction can also be realized in this position.
[0030] Figure 2 shows an intermediate position in which frames 2,3 now extend at an angle
of about 90°. In this position the frames 2,3 can for instance be placed in a corner.
It is noted that because of the construction according to the invention the frames
can be positioned in numerous positions relative to each other in step-free manner.
During the pivoting movement the frames can moreover remain permanently arranged on
the central support leg, which enables a rapid and efficient adjustment of the positions
of the frames. This is particularly important when the frames are used to bear relatively
heavy pieces of furniture such as cupboards and the like. It is also possible in such
a case to rotate the cupboards relative to each other, without the cupboards having
to be emptied to enable release of the frame from the support leg.
[0031] Figures 1 and 3 further show that the frames can be locked in the opened position
or in the closed position of support 1 using a locking element 16. The locking element
is shown in more detail in figure 6. This locking element can be displaced in the
direction of the arrow and fixed by a person to the outer ends 17 and 18 of frames
2 and 3 respectively. Element 16 is provided for this purpose with protrusions 19
which engage in corresponding openings 21,21' in the end edges of frames 2,3.
