Description

The present invention relates to an extendable table for furniture, in particular kitchen furniture, according to the preamble of claim 1.

Such pull-out tables are known from the prior art. They include a telescopic rail system with two multi-part telescopic rails arranged in parallel and two extendable plate parts. The plate parts are arranged one above the other when the pull-out table is pushed in. A first plate part is movable in the vertical direction, so that the surface of this plate part is lowered into a pull-out table level when the pull-out table is pulled out. In an extension position of the extension table, the surfaces of both panel parts are arranged in the plane of the extension table. The extendable table is equipped with a guide system for this purpose.

In the case of conventional pull-out tables, the guide system includes guide links that are permanently attached to the side of the furniture body and entrainment elements between the tabletop parts. The guide links lift the first panel part when it is pushed in in such a way that the panel parts are arranged one above the other in the pushed-in state. When the second plate part is pulled out, rear entrainment elements hit front entrainment elements of the first plate part about halfway along the entire path and then pull out the first plate part as well. As the pull-out table is moved further into the pull-out position, the first panel part falls down and thus occupies the same height as the second panel part in the vertical direction. Pulling out and pushing in the pull-out table has a jerky movement and is associated with additional noise.

In addition, other pull-out tables with different functionalities are known from the prior art. DE 20 2014 105 481 U1 , DE 20 2018 104 514 U1 and DE 20 2017 106 233 U1 each show pull-out folding tables in which a part of the top is manually folded down by 180° after being pulled out. DE 20 2015 102 257 U1 discloses an extendable table with a single unitary worktop that is raised by a lift fitting when extended. DE 7 821 362 U1 shows an extending table with two top parts, of which the rear top part is raised when the table is extended. From the DE 6 923 346 U an extendable ironing board is known with a lamellar structure and moving like a blind when being pulled in and out.

The object of the present invention is to provide an extendable table that is more user-friendly. The extendable table should also be able to be produced in a simple and cost-effective manner.

This object is achieved according to the characterizing part of claim 1 by a shear connector connecting the first plate part to the telescopic rail system and transmitting movements in the horizontal direction between the first plate part and the telescopic rail system. The horizontal direction is the direction in which the pull-out table is pulled out and pushed in. The vertical direction is perpendicular to this.

The first panel part is connected to the telescopic rail system by the sliding connector in such a way that a movement in the horizontal direction is transmitted from the telescopic rail system to the first panel part both when the pull-out table is pulled out and pushed in. At the same time, the first plate part remains movable in the vertical direction. The first plate part is lowered in particular by gravity. This is mechanically simple and can therefore be implemented in a cost-effective and low-maintenance manner.

The first panel part is permanently connected to the telescopic rail system by the shear connector. It is not necessary for further contact to be made with other parts of the extension table, in particular the telescopic rail system and/or the other plate part, such as the driver elements in the prior art, when the first plate part is lowered. This enables the pull-out table to be pulled out with little noise and little or no jerking. This also makes it easier to slide in the pull-out table, in particular with less noise and less jerking or without jerking. In particular, such a pull-out table can be pulled out by a unidirectional movement by means of a continuous harmonic movement. It can also be operated with just one hand and is therefore particularly convenient. In particular, the first plate part and the further plate part are each one-piece and solid plate parts.

Preferably, the guide system has two guide contours each fixed laterally on the furniture body. The guide contours can be fixed directly or indirectly to the furniture body. The guide contours are stationary relative to the furniture body. The guiding system further comprises two guiding side skirts arranged on the first plate part. The guide side skirts are the first Arranged th plate part that the other plate part is introduced in the inserted state at least partially in a delimited by the guide side skirts area. When the extension table is pushed in, the guide contours and the guide side skirts interact in such a way that the first panel part is raised at least by the thickness of the first panel part. In this way, the panel parts can be arranged one above the other when pushed in. The guide system can be implemented in a mechanically simple and therefore cost-effective and low-maintenance manner. In particular, the guide contours and the guide side skirts can interact in the manner of a link guide.

Particularly preferably, the guide contours and/or the guide side skirts form ramps, through which the first plate part is lifted when it is pushed in. This allows the management system to be designed in a particularly simple manner. The guide system can be implemented in a mechanically simple and therefore cost-effective and low-maintenance manner. More particularly preferably, the guide contours have U-shaped guide rails into which the guide side skirts are inserted when the pull-out table is pushed in. This further increases the reliability of the pull-out table and thus the ease of use in a simple manner.

The pull-out table preferably has side skirts arranged on the further top part. The side skirts arranged on the further plate part form a space between them, in which the telescopic rail system can be arranged at least in part. The side skirts cover the telescopic rail system in the extended position. As a result, the pull-out table has a valuable appearance in the pull-out position. In addition, the side skirts protect the telescopic rail system against accidental contact. This reduces the risk of an operator getting dirty or getting stuck on the telescopic rail system. If side skirts are arranged on the first panel part and on the further panel part, this can result in additional guidance of the pull-out table when transferring from the pulled-out position to the pushed-in state and vice versa. As a result, the reliability of the pull-out table and thus the ease of use can be further increased.

In the extended position, the first panel part particularly preferably rests at least partially on the side skirts arranged on the further panel part. In this way it can be achieved in a structurally simple manner that the surfaces of the two panel parts are arranged in an extension table plane in the extension position. This applies in particular if the first and the further plate part have the same thickness.

The first panel part is preferably formed by the rear panel part in the extension direction of the extension table. The other plate part forms the front plate part in the pull-out direction, which can then be firmly connected to the telescopic rail system. The extending table is particularly stable in the extended position. The front plate part can also be loaded when it is only partially extended. The ease of use of the pull-out table has been further improved. In particular, the area of the first panel part that has the push connector can then be arranged in such a way that this area of the rear panel part is still arranged inside the furniture carcass in the pulled-out position. As a result, a particularly valuable appearance of the pull-out table can be obtained in the pull-out position.

The shear connector is preferably formed by a projection which engages in a corresponding recess on the first plate part and is fixed to the telescopic rail system. The mobility of the first plate part in the vertical direction is retained by the projection engaging in a corresponding recess. Nevertheless, movements in the horizontal direction between the telescopic rail system and the first plate part can be transmitted by such a connection. Alternatively, the shear connector can also be formed by a projection which is arranged on the first plate part and engages in a corresponding recess on the telescopic rail system. The shear connector can thus be implemented in a mechanically simple and therefore cost-effective and low-maintenance manner.

Preferably, the multi-part telescopic rails are each formed by two pull-outs fixed to one another and in particular designed as three-part telescopic rails. In particular, extensions designed as three-part telescopic rails are easily available. By connecting the inner rail of one extension to the outer rail of the other extension, a multi-part telescopic rail for the telescopic rail system of the present extension table can be obtained in a simple manner. The extending table can be obtained in a simple and inexpensive manner.

Particularly preferably, an intermediate profile that forms the projection of the sliding connector is arranged between the two extensions. As a result, the push connector can be implemented in a particularly simple manner. Commercial extensions that are attached to each other can be fixed to one by using an intermediate profile can be combined in many ways to form a telescopic rail system with a shear connector. The extending table can be obtained in a particularly simple and inexpensive manner.

The telescopic rail system is preferably at least partially or quasi-synchronized. A telescopic rail system is partially or quasi-synchronized, in which the rails move in a synchronized manner at least in individual movement sections, in particular when the first or the further plate part is pulled out. In particular, pull-outs designed as three-part telescopic rails are easily available in a synchronized design. An extendable table with such a telescopic rail system is particularly stable and particularly easy to use. Ease of use is increased.

The telescopic rail system is preferably designed in such a way that, when it is pulled out, first the front panel part in the extension direction in the extended position and then the rear panel part in the extension direction is extended. This can be achieved in several ways. In particular, locking elements such as locking lugs can be provided on the telescopic rail system, which release the individual partial rails of the multi-part telescopic rails one after the other and/or friction components can be provided, as a result of which the effort required to pull out individual partial rails of the multi-part telescopic rails increases or decreases. Alternatively or additionally, spring elements can also be provided, via which the effort required to pull out individual partial rails of the multi-part telescopic rails can be adjusted accordingly. The fact that the two panel parts are moved one after the other when being pulled out reduces or eliminates the risk of a collision and/or jamming of the two panel parts. The reliability and ease of use of the extendable table is further increased.

Particularly preferably, the multi-part telescopic rails of the telescopic rail system are each formed by two extensions fixed to one another and in particular designed as three-part telescopic rails, with each extension being assigned a self-closing closing damper. Such self-retracting dampers are known. They have a spring, by means of which a moving component, typically a drawer, is transferred automatically and with a damped movement into the pushed-in position during a pushing-in process from a specific position, typically shortly before the pushed-in position. Such self-closing dampers increase the ease of use of moving components such as drawers. The spring force applied by the closing damper must be overcome when the component is pulled out. The draw-in damper assigned to the inner drawer is provided with a weaker spring than the draw-in damper assigned to the outer drawer. When pulling out, the closing damper assigned to the inner pull-out therefore initially releases the inner pull-out. Only when the inner extension is completely pulled out is a force transferred to the closing damper assigned to the outer extension, which then releases the outer extension. It is thus achieved in a simple manner that when the extension table is extended, first the panel part at the front in the extension direction in the extension position and then the panel part at the rear in the extension direction in the extension position is extended. At the same time, the use of self-retracting dampers dampens the retraction movement. Ease of use is further increased.

The pull-out table preferably includes a mishandling lock to prevent unintentional retraction from the pull-out position. A mishandling lock prevents the pull-out table from being unintentionally at least partially retracted from the pull-out position, in that a certain minimum effort has to be exceeded in order to be able to pull the pull-out table out of the pull-out position, and/or an additional handle is required to release a mishandling lock. The risk of objects falling off the pull-out table or an operator getting his fingers caught on the pull-out table when it is pushed in unintentionally is reduced by such a mishandling lock. The lateral stability of the pull-out table can also be increased by such a mishandling lock. The ease of use of the pull-out table is further increased.

The mishandling lock is particularly preferably formed by a self-retracting mishandling lock draw-in damper, which is arranged stationary opposite to the pull-out direction and adjacent to the opening of the furniture body, and a mishandling lock driver arranged on the telescopic rail system. When the pull-out table is pulled out, the mishandling lock driver engages with the mishandling lock retraction damper. The pull-out table is brought into the pull-out position automatically by a spring in the retraction damper that prevents mishandling. To slide in the pull-out table, the spring force of the mishandling lock retraction damper must be overcome. As a result, the pull-out table is secured against being pushed in unintentionally. In addition, the ease of use of the pull-out table is further increased.

More particularly preferably, the multi-part telescopic rails are each formed by two extensions fixed to one another and designed in particular as three-part telescopic rails, between which an intermediate profile is arranged, with the mishandling lock driver being arranged on the intermediate profile. In this case, a mishandling lock can be implemented in a simple and particularly reliable manner by means of a mishandling lock draw-in damper, which is in engagement with the mishandling lock driver in the pulled-out position. The inner pull-out cannot be moved because the front panel part is supported against the rear panel part, the first panel. Since the first plate is moved via the outer extension, but the mishandling lock driver arranged on the intermediate profile is engaged with the mishandling lock retraction damper, the outer telescopic rail can only be moved when the spring force of the spring of the mishandling lock retraction damper has been overcome . A mishandling lock can thus be implemented in a simple manner and the ease of use of the pull-out table can be further increased.

Further advantages and details of the invention can be found in the following description of the figures with exemplary embodiments according to the invention. In the figures shows in a schematic way:

• 1 an extending table according to the invention in the retracted state;
• 2 according to the extendable table 1 in the extended position;
• 3 a detailed view of the pull-out table in the pull-out position according to FIG 2 ;
• 4 a partial exploded view of a telescopic rail of the telescopic rail system of the extendable table according to FIG 1 ;
• 5 one side of the telescopic rail system of the extendable table 1 .

Parts that function in the same or a similar way are provided with identical reference numbers where appropriate. Individual technical features of the exemplary embodiments described below can be combined with the features of claim 1 and with the features of individual exemplary embodiments described above to form objects according to the invention.

1 shows an extending table 2 according to the invention in a pushed-in state. The pull-out table 2 has two plate parts 4, 6 arranged one above the other when pushed in. Plate part 4 is movable in the vertical direction and is arranged above the further plate part 6 in the pushed-in state. The extending table 2 also includes a telescopic rail system 8 on which the plate parts 4.6 are fixed. The first panel part 4 is connected to the telescopic rail system 8 via a shear connector 10 . In the present case, the shear connector 10 is designed as a projection 12 which engages in a corresponding recess 14 on the first plate part 4 . The projection 12 transmits movements in the horizontal direction HR, ie in the extension and retraction direction of the extension table 2, between the first panel part 4 and the telescopic rail system 8, the first panel part 4 remaining movable in the vertical direction perpendicular to the horizontal direction.

The first panel part 4 is lifted in the vertical direction against the force of gravity when it is pushed in via a guide system 16 . When pulled out, the first panel part 4 is lowered by gravity. The first panel part 4 is thereby raised by at least the thickness of the first panel part 4 . The use of plate parts with a small thickness is therefore particularly advantageous. The smaller the thickness of at least the first plate part 4, the smaller the necessary movement in the vertical direction. In the present exemplary embodiment, the guide system 16 is formed by guide side skirts 18 arranged on the first panel part 4 and guide contours 20 arranged stationary on a furniture body. When the extension table 2 is pushed in, the guide side skirts 18 interact with the guide contours 20 in such a way that the first panel part 4 is lifted. In the exemplary embodiment, the guide side skirts 18 and the guide contours 20 have ramps 22,24. The guide contours 20 are designed as U-shaped profiles that are arranged on the side of the telescopic rail system 8 . The guide side skirts 18 can be securely accommodated and guided in the U-shaped profiles.

2 shows the extendable table 2 according to FIG 1 in the extended position. The telescopic rail system 8 is fully extended. The plate parts 4.6 are arranged one behind the other and their surfaces in an extension table level. The rear panel part 4 is lowered compared to the pushed-in state. This can be seen, among other things, from the projections 12 of the push connector 10, which in the pulled-out position protrude significantly more than the first plate part 4, since the first plate part 4 was lowered in the vertical direction. This is in 3 enlarged again. The first plate part 4 is wider than the further plate part 6. The further plate part 6 is provided with side skirts 19. The further panel part 6 with the side skirts 19 can be arranged within a space delimited by the guide side skirts 18 of the first panel part 4 the. The side skirts 19 of the further panel part 6 create a valuable appearance of the pull-out table 2 in the pull-out position. The telescopic rail system 8 is at least partially covered by the side skirts 19 when viewed from the side.

4 shows part of the telescopic rail system 8 in a partially exploded view. The multi-part telescopic rails 26 are formed by two three-part telescopic rails in the form of extracts 28.30. These are each synchronized excerpts 28.30. The use of synchronized three-piece extensions 28, 30 makes it possible to obtain 5-piece, quasi-synchronized telescopic slides 26 in a simple manner. Between the inner rail of the outer extension 28 and the outer rail of the inner extension 30 there is an intermediate profile 32 , designed here as an intermediate plate, which forms the projection 12 of the sliding connector 10 . The shear connector 10 can thus be formed on the telescopic rail 26 in a simple manner. In addition, each statement 28.30 can have its own in 4 be assigned not shown self-retracting damper. The retraction dampers each have a spring element against whose resistance the respective extract 28,30 must be pulled out. The retraction damper assigned to the inner extension 30 has a weaker spring than the retraction damper assigned to the outer extension 28 . This ensures that when the pull-out table is pulled out, the inner pull-out 30 is first pulled out with the further plate part 6 . The outer drawer 28 with the first plate part 4 is only then released when the inner drawer 30 is fully extended. This makes it easy to ensure that the first plate part 4 does not collide with the other plate part 6 when it is lowered.

5 shows a part of the telescopic rail system 8 with a mishandling lock 34. The mishandling lock 34 comprises a mishandling lock driver 36 and a mishandling lock retraction damper 38. The mishandling lock driver 36 is arranged on the intermediate profile 32. When the extension table 2 is pulled out, the retraction damper 38 to prevent incorrect operation and the driver 36 to prevent incorrect operation come into engagement with one another. A spring in the mishandling lock retraction damper 38 moves the pull-out table 2 into the pull-out position, the fully pulled-out state, in a dampened movement. This spring force must be overcome to push in the pull-out table 2. As a result, the pull-out table 2 is secured against accidental insertion. The mishandling lock 34 is preferably provided on both sides of the telescopic rail system 8 . This improves the lateral stability of the pull-out table 2 in the pull-out position.
