Description

The invention relates to a frame furniture with the features of the preamble of claim 1.

Such a frame furniture is known in practice and comprises a plate and two leg members carrying the plate. The leg elements are arranged on both sides of a vertical furniture center plane or on two opposite sides of the frame furniture. The two leg elements are movably mounted. For stacking the frame furniture, the leg elements can for example be pivoted to come to rest on the underside of the plate. A generic frame furniture is for example from the WO 2012/054799 A1 known.

For pivoting the leg members, however, a complex adjustment mechanism is necessary. In addition, such a frame furniture for pivoting the leg members must be at least tilted, which is possibly associated with high expenditure of force and can also lead to damage to the frame furniture or injury to the user.

The invention is therefore an object of the invention to provide a frame furniture of the aforementioned type, which is characterized by good stackability and in particular by a simple adjustment of the leg elements.

This object is achieved by the frame furniture with the features of claim 1.

According to the invention, therefore, a frame furniture is proposed, comprising a plate and two plate-carrying leg elements, which are arranged on both sides of a vertical furniture center plane and movably mounted. The leg members are each between a normal position in which the leg elements are covered by the plate, and one Adjustable position adjustable, in which the leg elements are exposed upwards to make the frame furniture on the leg elements stackable.

By means of a simple adjustment so frame furniture of the same design can be stacked to save space, and in fact that are pulled out for stacking the frame furniture or for producing the extended position of the leg members, the leg elements under the plate. The leg elements are therefore arranged in their extended position next to the plate and therefore run during stacking next to the plates below arranged frame furniture. The frame furniture according to the invention is thus easy and space-saving stackable.

In a preferred embodiment of the frame furniture according to the invention, the leg members are each arranged on an extension support which is displaceable perpendicular to the furniture center plane. Thus, the leg members can be moved out between their normal position and their extended position. For a simple adjustment mechanism is realized, the leg elements can maintain their orientation to the plate substantially even in a stacking frame furniture of the same type.

In a further preferred embodiment of the frame furniture according to the invention, the drawer slides are guided on a support frame which is fixed to the underside of the plate. The support frame thus forms a basis for the extract carrier and can also increase the rigidity of the plate.

In a further preferred embodiment of the frame furniture according to the invention each leg member is associated with a clamping lever which is adjustable between a release position in which the corresponding leg member is adjustable, and a locking position in which the corresponding leg member is jammed. The clamping lever can thus determine the normal position and the extension position of the corresponding leg member and thereby prevents unwanted movement of the respective leg member.

In a further preferred embodiment of the frame furniture according to the invention, the clamping lever is designed as an eccentric lever. It is with an eccentric lever possible to securely set or release the locking position of the clamping lever with little effort.

In a further preferred embodiment of the frame furniture according to the invention, the clamping lever engages in a clamping slot of the drawer carrier, each having a pull-out position and a clamping position defining the normal position. The Klemmkulisse is thus formed in two stages. However, it is also conceivable to provide several stages or execute the leg elements continuously adjustable.

According to the invention, the leg elements are each formed from a tubular element that is bent to form a front and a rear furniture leg, wherein the tubular elements each have an elliptical or oval cross-section with a long major axis and a short minor axis and the major axis and the minor axis cut the vertical furniture center plane over the extension of the respective pipe element at an angle smaller than 90 °.

The essence of the invention is therefore that the bent tubular elements an elliptical or oval, d. H. have a non-circular cross section and the bending of the tubular elements is not about the major axis or the minor axis of the ellipse formed by the cross section at the apex of the tubular element, but via an axis which lies between the respective minor axis and the respective major axis. This axis is then aligned with respect to the vertical furniture center plane, at least substantially in the transverse direction, whereas an axis aligned at right angles to this axis lies in a plane which is spanned by the main axis of the relevant tubular element. Thus, a good stack spacing between frame furniture of the same design can be created. At the same time, the tube elements act as a kind of cone, which aligns the frame furniture in the stacked state exactly to each other.

The term "elliptical" in the present case in its broadest sense, ie not strictly mathematical to understand. Rather, this term describes that the tube element does not have a circular cross-section, but an at least flattened round cross-section. The largest diameter forms the long main axis, whereas the smallest diameter forms the short minor axis, which is aligned at right angles to the long major axis.

In a further preferred embodiment of the frame furniture according to the invention, the main axis over the extension of the respective pipe element in the direction of the furniture center plane up and the minor axis over the extension of the respective pipe element in the direction of the furniture center plane down. The bearing surfaces formed by the two leg elements when stacking the frame furniture thus point inwards on the tube element underside, ie. in the direction of the median plane, and above, i. on the visible side, outward away from the median plane.

Be particularly useful in terms of stacking behavior of the frame furniture has proven a major axis that intersects the vertical center plane at an angle between 30 ° and 60 °.

In order to achieve as rattle-free storage of the frame furniture of the same type in the stacked state, a stack buffer may be provided which is suitably embraced by the curvature portion which forms a region of the respective tubular element which lies between the two furniture legs of the respective leg member.

The stack buffer can have a linking element, via which the frame furniture can be linked with a frame furniture of the same design.

In order to facilitate the stacking process, the furniture legs may each have a stack guide at their end regions, which rests in the stacked state on a furniture leg of a frame furniture of the same design.

The frame furniture can be both a table and a bench.

Further advantages and advantageous embodiments of the frame furniture according to the invention are the description, the drawings and claims removed.

FIG. 1 shows two frame furniture in one embodiment as tables 1,1 'of the same type, which are stacked and each having a plate 2. The plates 2 are each supported by two leg elements 4, which are arranged on both sides of a respective vertical furniture center plane or table center plane and of which in the present case only one of the clarity is shown. The leg elements 4 are in FIG. 1 shown in a pulled position and thus not covered by a plate 2, ie the leg members 4 are released upwards, so that a stacking of the tables 1, 1 'on the leg members is possible.

On the underside of the plate 10 of the plate 2, a respective support frame 8 is fixed, on which for each leg member 4, an extension support 6 is guided, which is displaceable perpendicular to the table center plane. On the extension support 6, the respective leg member 4 is arranged, which consists of a bent tubular element which forms a respective front furniture leg 18A and a respective rear furniture leg 18B. The furniture legs 18A, 18B are above an upper curvature portion 20 of the respective Tube element connected to each other and run downwards, ie in the direction of a footprint, V-shaped apart, wherein of the furniture legs 18A, 18B of the two leg members 4 of a table 1, 1 'parallel planes are spanned.

The tubular elements from which the furniture legs 18A, 18B are formed each have a broadly elliptical cross-section with a long major axis and a short minor axis, such as FIGS. 3 to 6 demonstrate. Over the entire extent of the respective tubular element, ie also in the respective curved section 20, the long main axis of the ellipse formed by the cross section in the direction of the vertical table center plane upward, so that the two leg members 4 form a stacking aid in the manner of a downwardly opening cone , By the juxtaposition of the leg members 4 on one side of the table and the leg members 4 on the other side of the table stacked tables 1, 1 'are secured. The tubular elements are thus bent over an axis of the cross-sectional ellipse arranged in the apex, which axis lies between the respective main axis and the respective minor axis and with the main axis preferably spans an angle between 45 ° and 60 °.

The main axis of the elliptical pipe element cross sections thus intersects the vertical table center plane at an angle of about 30 ° to 45 °, over the entire extent of the tubular elements.

The curved sections 20 of the leg elements 4 respectively enclose a stacking buffer 22, which in the stacked state rests with a support surface 28 on a curved section 20 of a leg element 4 of an underlying table 1 '. The support surface 28 has a shape that is adapted to the outer surface of the respective curvature portion 20. Furthermore, the stack buffers 22 on their side facing away from the middle plane of the table each have a linking element, which in the present case on the side of the leg member 4 as a projection 30 and on the opposite side of the leg member 4 of a table 1, 1 'is formed as a recess with corresponds to the projection 30.

In the foot area, the furniture legs 18A, 18B each have a foot insert 32 made of plastic, on which in one piece on the respective furniture leg inside adjacent stack guide 34 is formed. The stack guides 34 lie in the stacked state of the tables 1, 1 'on the outside of the respective furniture leg 18A, 18B.

The upwardly released leg elements 4 of stacked tables 1,1 'of the same design shows FIG. 2 in a side view. The leg members 4 are shown in their extended position and relative to their respective normal position relative to the vertical table center plane offset by about 60 mm to the outside. The leg members 4 of the upper table 1 thus run past the plate 2 of the lower table 1 'or are arranged next to the plate 2 of the lower table 1' in order to engage over its respective leg element 4.

FIG. 3 shows the leg member 4 in its normal position, in which it is completely covered by the plate 2. The leg member 4 is so far covered by the plate 2, that a largely continuous plate surface can be formed by a concatenation with another table of the same type on the projection 30 and the corresponding recess.

For producing the extended position of a leg member 4, a clamping lever 12 is pivoted away in its release position of the plate 2, such as FIG. 4 shows. The clamping lever 12 is designed as an eccentric lever and engages in a clamping slot 14 of the drawer carrier 6 a. The Klemmkulisse 14 of the drawer carrier 6 each has a pull-out position and the normal position defining clamping recess 16, wherein FIG. 4 only the clamping position defining the normal position 16 shows. Once the extract carrier 6 is released or no longer jammed, it can be moved together with the leg member 4, wherein the distance is defined by the length of the clamping gate 14. Thus, the pullout or stacking position of the leg element can be determined (see. FIG. 5 ).

To secure the extended position of the clamping lever 12 can be pivoted in its blocking position in the direction of the plate 2 to define the corresponding with the corresponding clamping recess 16 normal position or extended position of the respective leg member 4 (see. FIG. 6 ). In this case, the clamping lever 12 engages in the corresponding clamping recess 16 and jams the drawer carrier 6 and thus also the leg member 4, whereby this is secured against accidental displacement.

The adjustment of the leg member 4 from the extended position or stacking position in the normal position takes place in the reverse manner.

In the FIG. 7 shown seat 36 has a plate 2, which is supported by two leg members 4, which are arranged on both sides of a vertical furniture center plane or bank median plane. The leg members 4 of the seat 36 are made shorter than the leg members 4 of the table 1, 1 '. The leg elements 4 are in FIG. 7 shown in normal position and thus covered by the plate 2, ie the leg members 4 are not released upwards, so that a stacking of the seat 36 via the leg members 4 is not possible. The leg members 4 are so far covered by the plate 2, that by a concatenation with another seat of the same design via a projection 30 and the corresponding recess a substantially continuous plate surface or seat can be formed.

On the underside of the plate 10 of the plate 2, a respective support frame 8 is fixed, on which for each leg member 4, an extension support 6 is guided, which is displaceable perpendicular to the median plane of the bank. On the extension support 6, the respective leg member 4 is arranged, which consists of a bent tubular element which forms a respective front furniture leg 18A and a respective rear furniture leg 18B. The furniture legs 18A, 18B are connected to each other via an upper curvature portion 20 of the respective tubular member and run downwards, i. in the direction of a footprint, V-shaped apart, wherein the furniture legs 18A, 18B of the two leg members 4 of the seat 36 are parallel planes spanned.

The tubular elements of which the furniture legs 18A, 18B are formed each have a broadly elliptical cross-section with a long major axis and a short minor axis, as in FIGS FIGS. 3 to 6 in connection with a table 1,1 'is shown in detail. Over the entire extension of the respective tubular element, ie also in the respective curved section 20, the long main axis of the ellipse formed by the cross section in the direction of the vertical median plane, so that the two leg members 4 a stacking aid in the manner of a forming the bottom opening cone. When stacking benches 36 of the same type, the stacked seats 36 are secured by the juxtaposition of the leg members 4 on one side of the bank and the leg members 4 on the other side of the bank. The tubular elements are thus bent over an axis of the cross-sectional ellipse arranged in the apex, which axis lies between the respective main axis and the respective minor axis and with the main axis preferably spans an angle between 45 ° and 60 °.

The main axis of the elliptical pipe element cross sections thus intersects the vertical bank center plane at an angle of about 30 ° to 45 °, over the entire extent of the tubular elements.

The curved sections 20 of the leg elements 4 each enclose a stacking buffer 22 which, in the stacked state, can rest on a curvature section 20 of a leg element 4 of an underlying bench seat with a bearing surface 28. The support surface 28 has a shape that is adapted to the outer surface of the respective curvature portion 20. Furthermore, the stacking buffers 22 have on their side facing away from the median plane each a linking element, which is formed in the present case on the imaged foreground image of the leg member 4 as a projection 30 and on the opposite side of the leg member 4 of the seat 36 as a recess with corresponds to the projection 30.

In the foot area, the furniture legs 18A, 18B each have a foot insert 32 made of plastic, on which is integrally formed a stacking guide 34 abutting the respective furniture leg inner side. The stack guides 34 are in the stacked state of the seats 36 on the outside of the respective furniture leg 18A, 18B.

The adjusting mechanism described in connection with the table 1,1 ', comprising the clamping lever 12, the clamping slot 14 and the clamping recesses 16, is analogous to the table 1,1' also in the in FIG. 7 realized seat 36 realized.

With reference to the in the FIGS. 4 to 6 shown table 1 and the reference numerals used for this will be below the adjustment of a leg member 4 of Seat 36 explained. For producing the extended position of a leg member 4 of a seat 36, a clamping lever 12 is pivoted away in its release position of the plate 2, as already FIG. 4 in connection with a table 1,1 'shows. The clamping lever 12 is designed as an eccentric lever and engages in a clamping slot 14 of the drawer carrier 6 a. The Klemmkulisse 14 of the drawer carrier 6 each has a pull-out position and the normal position defining clamping recess 16, wherein FIG. 4 only the clamping position defining the normal position 16 shows. Once the extract carrier 6 is released or no longer jammed, it can be moved together with the leg member 4, wherein the distance is defined by the length of the clamping link 14 and can be about 60 mm. Thus, the pullout or stacking position of the leg member 4 can be set.

To secure the extended position of the clamping lever 12 can be pivoted in its blocking position in the direction of the plate 2 to define the corresponding with the corresponding clamping recess 16 normal position or extended position of the respective leg member 4 (see. FIG. 6 ). In this case, the clamping lever 12 engages in the corresponding clamping recess 16 and jams the drawer support 6 and thus also the leg member 4, whereby this is secured against accidental displacement.

The adjustment of the leg member 4 from the extended position or stacking position in the normal position takes place in the reverse manner.
