Technical Field
[0001] The present invention relates to an assembly having at least one folding door or folding sliding door, the folding door or folding sliding door comprising at least two hingedly connected door leaves, wherein at least one ejection device arranged on a first of the two door leaves serves to at least partially transfer the at least one folding door or folding sliding door from a folded, open position into a closed position, in which the at least two door leaves are arranged in a common closing plane and at least one retaining element arranged on a second of the two door leaves is provided, wherein the ejection device has at least one ejection element. The present invention also relates to a piece of furniture having a fixed furniture part and at least one such assembly. Background Art
[0002] Known by prior art for folding door or folding sliding door being transferred to the assembly in the closed position from open position. Disadvantageous at this is that folding door or folding sliding door also may undesirably move to the direction of closed position owing to the accidental touch of user. Summary of the Invention
[0003] The object of the present invention is to provide a component which is improved compared to the prior art and a piece of furniture having at least one such component.
[0004] These objects are achieved by the features of claims 1 and 25 .
[0005] Therefore, according to the present invention, the at least one pushing element can engage with a retaining element in the open position so as to hold the at least one folding door or folding sliding door in the open position, and the at least one pushing element is designed to apply a force to the retaining element so as to move the second door leaf from the open position to the closed position.
[0006] The folding door or folding sliding door is thus held in the open position by the ejection device and the retaining element and is therefore locked against undesired movement. If the folding door or folding sliding door is to be closed, a force can be applied to the retaining element by the ejection device, thereby assisting the closing process.
[0007] The ejection element has a dual function. On the one hand, the folding door or folding sliding door can be kept in the open position by the ejection element. On the other hand, the folding door or folding sliding door can be moved in the direction of the closed position by the ejection element.
[0008] In a furniture arrangement having such an assembly, the at least one folding door or folding-sliding door is supported on at least one fixed furniture part.
[0009] Further advantageous embodiments of the invention are defined in the dependent claims.
[0010] It can be provided that the at least one ejection element has an engagement opening, wherein a locking bolt of the retaining element can engage with the engagement opening.
[0011] This provides a simple possibility of producing the engagement between the retaining element and the ejection element.
[0012] Preferably, it can be provided that the at least one ejection device has at least one locking device for releasably locking the holding element to the at least one ejection element.
[0013] The locking device ensures that the engagement between the retaining element and the ejection element cannot be released unintentionally.
[0014] It can preferably be provided that, when the ejection device is mounted, the at least one locking device can be unlocked by exerting pressure on the folding door or folding and sliding door, preferably in the region in which the retaining element is arranged.
[0015] This constitutes a simple and intuitive possibility of releasing the locking device.
[0016] In this context, it can particularly preferably be provided that the folding door or folding and sliding door is compressed beyond the open position by applying pressure when unlocking.
[0017] This also increases the security against unintentional release of the locking device.
[0018] According to a further embodiment, it can be provided that the locking device comprises at least one control curve, preferably a heart-shaped control curve, wherein at least one control pin arranged or formed on the at least one ejection element is provided and guided in the control curve.
[0019] By means of the control curve and the control pin, the ejection element can be guided in a simple manner in such a way that it can not only engage with the retaining element but also exert a force on the retaining element.
[0020] Preferably, it can be provided that the ejection element is acted upon by means of at least one force accumulator which is acted upon manually by a user, wherein the force accumulator preferably comprises at least one helical torsion spring.
[0021] Thus, the user can load the force accumulator when opening the folding door or folding sliding door.When the folding door or folding sliding door is closed, the force stored in the force accumulator can then be used to exert force on the retaining element and thus assist the closing process of the folding door or folding sliding door.
[0022] According to a further embodiment, the at least one ejection element can be locked via a locking device in a manner counter to the force exerted by the at least one charged force accumulator.
[0023] This provides a simple possibility of keeping the force stored in the force accumulator available until it is used.
[0024] It can preferably be provided that the ejection device comprises at least one, preferably two, support elements.
[0025] Particularly preferably, it can be provided that the at least one ejection element is pivotably mounted on the at least one bearing element.
[0026] Furthermore, it can be provided that the support element has at least one fastening section for fastening the at least one support element to the door leaf.
[0027] The support element provides a simple constructional possibility for arranging the ejection element in a pivotable manner on the door leaf.
[0028] According to one embodiment, it can be provided that the control curve is formed on at least one support element.
[0029] The control curve can thus be realized in a space-saving manner and with low production outlay.
[0030] Advantageously, the ejection device comprises at least one limiting device for limiting the rotational movement of the at least one ejection element.
[0031] By means of such a limiting device it can be ensured that the ejection element can only be moved within a permissible range, whereby an undesired movement of the folding door or folding-sliding door from the open position to the closed position can also be counteracted.
[0032] It can be provided that the limiting device comprises at least one limiting curve, wherein a limiting pin arranged or formed on the at least one ejection element is guided in the limiting curve.
[0033] This provides a simple possibility of implementing the limiting device.
[0034] If the limiting curve is formed on at least one support element, the limiting device can be designed in a space-saving manner.
[0035] Preferably, it can be provided that at least one force accumulator acts between at least one supporting element and at least one ejection element.
[0036] As a result, the at least one force accumulator can be integrated into the ejection device in a space-saving manner.
[0037] Advantageously, at least two ejection elements can be provided, wherein the at least two ejection elements are pivotably mounted on a common axis.
[0038] This increases the stability and fault reliability of the ejection device.
[0039] Preferably, it can be provided that at least one ejection element comprises a pivoting element and an engagement element.
[0040] Particularly preferably, it can be provided that the control pin and / or the limiting pin are arranged or formed on the pivot element and / or that the pivot element has a receptacle for at least partially accommodating the force accumulator.
[0041] Furthermore, it can be provided that the engagement element has an engagement opening.
[0042] Thus, the retaining element engages with a component of the ejection element (engaging element). However, the force is applied to the retaining element by another component of the ejection element (the swing element). This structural separation allows the respective components to be better adapted to their respective functions.
[0043] Furthermore, it can be provided that the ejection device has at least one overload protection device.
[0044] The overload protection device can ensure, for example, that the user does not damage the ejection device if he attempts to close the folding door or folding sliding door incorrectly.
[0045] According to one embodiment, it can be provided that the pivot element and the engaging element are components of the overload protection device, wherein the engaging element has a control contour that can be acted upon by the second force accumulator.
[0046] It can also be provided that the engagement element can be pivoted relative to the pivot element when a predetermined force is reached, counter to the force applied by the second force accumulator.
[0047] This provides a simple possibility for implementing overload protection.
[0048] Preferably, it can be provided here that the second force accumulator is mounted on or in the pivot element.
[0049] This allows the space requirement of the overload protection device to be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0063] Figure 1a shows a schematic perspective view of the furniture 100 in the closed position, Figure 1b A schematic perspective view of a piece of furniture 100 in an open position is shown. As can be seen, the piece of furniture 100 comprises a fixed furniture part 101 , here in the form of a furniture carcass. A folding sliding door 102 is supported on the fixed furniture part 101 .
[0064] The folding sliding door 102 comprises two door leaves 102a, 102b which are hinged to each other. Here, the first door leaf 102a is hingedly connected to the fixed furniture part 101, while the second door leaf 102b is slidably supported on a guide rail 103.
[0065] The folding sliding door 102 can be moved from the closed position ( Figure 1a ) to the open position ( Figure 1b ), thereby making the interior of the fixed furniture part 101 accessible.
[0066] Figures 2a to 2c A schematic top view shows the opening process of the piece of furniture 100 or the closing process in reverse order.
[0067] In the closed position ( Figure 2a ), the door leaves 102a, 102b are essentially in a common closing plane. The guide rail 103 is not shown for the sake of clarity.
[0068] Arranged on the first door leaf 102a is an ejection device 2 and on the second door leaf 102b is a holding element 3. When opening the folding sliding door 102, the two door leaves 102a, 102b are moved towards each other until they are arranged in the folded position.
[0069] Here, the holding element 3 engages with the ejection element 4 of the ejection device 2, thereby holding the folding sliding door 102 in the open position. To close the folding sliding door 102, the second door leaf 102b can be pushed in the area of the holding element 3 toward the first door leaf 102a. This releases the engagement between the holding element 3 and the ejection element 4. Furthermore, the ejection element 4 exerts a force on the holding element 3, thereby moving the folding sliding door 102 at least partially toward the closed position.
[0070] Figure 3a shows a schematic perspective view of the ejection device 2 and the holding element 3, Figure 3b A schematic side view of the ejection device 2 and the retaining element 3 is shown.
[0071] The ejection device 2 comprises two supporting devices 7 on which the ejection element 4 is pivotably supported. It can also be seen that the ejection element 4 is designed in two parts. The engagement elements 4b each have an engagement opening 4c in which the locking bolt 3a of the retaining element can engage. Figure 4 The individual elements of the ejection device are also shown in more detail.
[0072] Figure 4 A schematic exploded view of the ejection device 2 and the retaining element 3 is shown. As already described, the ejection element 4 is pivotably mounted on the support element 7. For this purpose, a bolt 10 is provided, on which the two ejection elements 4 are arranged together. The bolt 10 is mounted in a recess 7b. Furthermore, the support element 7 includes a fastening section 7a, via which the support element 7 can be fastened to the door leaf 102a. In this embodiment, the support section 7a has an opening for accommodating a screw. However, in principle, various fastening options are conceivable.
[0073] The ejection element 4 consists of a swing element 4a and an engagement element 4b. In normal conditions, the swing element 4a and the engagement element 4b are coupled in motion via a second force accumulator 9b, which is arranged in an opening 4f in the swing element 4a and applies a force to the control contour 9a of the engagement element 4b. However, in the event of an overload, the engagement element 4b can move relative to the swing element 4a. This is Figures 8a to 8c The second force accumulator 9b is designed as an elastic spherical pressure piece in this embodiment.
[0074] Furthermore, a force accumulator 6 is arranged in the recess 7b. Here, the force accumulator 6 is designed as a helical torsion spring that is wound around the bolt 10. One leg of the force accumulator 6 is supported in the recess 7b, while the second leg is located in a recess in the pivot element 4a. If the pivot element 4a is moved accordingly relative to the support element 7, the force accumulator 6 can be charged.
[0075] Furthermore, the control curve 5a and the limiting curve 8a can be seen in the support element 7. A limiting pin 8b is guided in the limiting curve 8a and is supported in a guide hole 4d in the pivot element 4a. The control pin 5b is guided in the control curve 5a. The control pin 5b is slidably supported in a guide groove 4e of the pivot element 4a.
[0076] Spacers 11 are provided between the support devices 7 , which space the support devices 7 apart from each other at a predetermined distance.
[0077] With the help of Figures 5a to 5k 、 Figures 6a to 6k and Figures 7a to 7k The operation of the ejection device 2 during the opening or closing process of the folding sliding door 102 will be described. Figures 5a to 5k Here, the corresponding steps are shown respectively according to Figure 3b Section AA, Figures 6a to 6k The cross section BB is shown respectively, and Figures 7a to 7k The same abbreviations here respectively denote the same steps.
[0078] exist Figure 5a 、 Figure 6a and Figure 7a As can be seen in the figure, the folding sliding door 102 is not yet fully opened. The locking pin 3a of the retaining element 3 is not in contact with the ejection device 2. The ejection element 4 is pushed toward the retaining element 3 by the force accumulator 6. The limiting pin 8a is located at the outermost left end of the limiting curve 8b and thereby prevents the ejection element 4 from moving further toward the retaining element 3.
[0079] In the next step ( Figure 5b 、 Figure 6b 、 Figure 7b), the locking bolt 3a contacts the swing element 4. Then, the swing element 4 swings against the force of the force accumulator 6. Here, the control bolt 5b and the limiting bolt 8b move in their respective guide curves 5a, 8a ( Figure 5c 、 Figure 6c 、 Figure 7c ). The control curve 5a is configured as a cardioid curve.
[0080] Subsequently, the ejection member 4 is further swung, whereby the locking bolt 3a is engaged with the engagement opening 4c of the engagement member 4b ( Figure 5d 、 Figure 6d 、 Figure 7d ).
[0081] The ejection element 4 continues to swivel in the direction of the first door leaf 102a, whereby the control bolt 5a moves in the control curve 5b over the upper protrusion ( Figure 5e 、 Figure 6e 、 Figure 7e ).
[0082] Finally, the ejection element 4 reaches a second end position in which the limiting bolt 8b and the limiting curve 8a prevent further movement of the ejection element 4 ( Figure 5f 、 Figure 6f 、 Figure 7f ). Therefore, the limiting bolt 8b and the limiting curve 8a constitute the limiting device 8.
[0083] As soon as the user does not apply pressure to the door leaf 102b and therefore to the retaining element 3, the ejection element 4 is pressed again in the direction of the second door leaf 102b by the force accumulator 6 until the control bolt 5b is locked in the locking point of the control curve 5a ( Figure 5g 、 Figure 6g 、 Figure 7g The folding sliding door 102 is in the open position. The folding sliding door 102 is held in the open position by the ejection device 2 and the retaining element 3 by the locking pin 3a engaging in the engagement opening 4c. The control curve 5a and the control pin 5b thus form a locking device 5, by means of which the engagement between the locking pin 3a and the ejection element 4 can be locked.
[0084] To close the folding sliding door 102, the second door leaf 102b and thus the retaining element 3 are pushed in the direction of the first door leaf 102a. This causes the ejection element 4 to pivot again. The control bolt 5b moves out of its locking position and is guided downwards along the control curve 5a ( Figure 5h 、 Figure 6h 、 Figure 7h ). Thus, when the folding sliding door 102 is unlocked, it is pressed beyond the open position by applying pressure to the second door leaf 102b. Here, the force accumulator 6 is also additionally loaded.
[0085] The force accumulator 6 causes the ejection element 4 to move toward the second door leaf 102b ( Figure 5i 、 Figure 6i 、 Figure 7i ), until the locking bolt 4a is released by the pushing element 4 ( Figure 5j 、 Figure 6j 、 Figure 7j ) and is pushed out by the force stored in the accumulator 6 ( Figure 5k 、 Figure 6k 、 Figure 7k ). Here, the push-out element 4 is prevented from further movement by the limiting bolt 8b and the limiting curve 8a. By exerting a force on the push-out element 4, the retaining element 3 and thus the second door leaf 102b are moved, whereby the folding sliding door 102 is at least partially transferred to the closed position.
[0086] Figure 8a shows an exploded view of the ejection element 4, Figure 8b shows a schematic perspective view of the ejection element 4, and Figure 8c A schematic perspective view of the ejection element 4 is shown in the overload situation.
[0087] It can also be seen that the swing element 4a has a control contour 9a. A second force accumulator 9b in the form of an elastic spherical pressure piece is arranged in an opening 4f in the swing element 4a and exerts a force on the control contour 9a. The ball of the spherical pressure piece is thus pressed against the control contour 9a, thereby establishing a kinematic coupling between the swing element 4a and the coupling element 4b.
[0088] In the event of an overload, for example when a user pulls on the second door leaf 102b while the folding sliding door 102 is locked in the open position, the second force accumulator 9b is compressed by the control contour 9a. As a result, the engagement element 4b pivots relative to the pivot element 4a, which is locked by the control pin 5b and the control curve 5a, thereby releasing the locking pin 3a. The control contour 9a and the force accumulator 9b thus form the overload protection device 9.
[0089] This prevents the ejection device 2 from being damaged in the event of an overload.
