Description

[Technical Field]

[0001] The present invention provides a guide system for guiding at least one door relative to a furniture cabinet, comprising: at least one guide configured to guide at least one door along a side wall of the furniture cabinet; - at least one support movably supported along at least one guide, on which at least one door can be pivotally supported over a pivot path between a first position and a second position; The present invention relates to a guide system including:

[0002] The invention further relates to an assembly comprising a guide system of the kind described and at least one furniture hinge arranged on a support and separate from the drive.

[0003] Finally, the invention relates to a piece of furniture comprising a furniture cabinet, at least one door movable relative to the furniture cabinet, and at least one guide system of the kind described.

[0004] A guide system of the aforementioned type for guiding a movable door is shown, for example, in WO 2020 / 097644. The door is pivotally supported via two or more furniture hinges on a longitudinally extending support that extends vertically in the assembly position. The support can be moved along a guide attached to a side wall of the furniture cabinet to push the door into a lateral push-in pocket of the furniture cabinet. The door is movable between a first position in which the door is aligned substantially perpendicular to the side wall of the furniture cabinet and a second position in which the door is aligned substantially parallel to the side wall of the furniture cabinet.

[0005] A drawback of the prior art is that the door may take an undefined intermediate position relative to the support, in which case the door may collide with the side wall or the furniture cabinet may not be completely closed by the door.

[0006] The object of the present invention is to provide a guide system of the type mentioned at the outset which avoids the above-mentioned disadvantages.

[0007] This problem is solved according to the invention by the features of claim 1. Further advantageous embodiments of the invention are defined in the dependent claims.

[0008] According to the invention, it is provided that at least one drive device is arranged on the support or on the mounting part to be attached to the support, by means of which the door connected to the support in the mounted state can be driven into a first position and / or a second position at least in a partial section of the pivot path.

[0009] Thus, at least one door can be moved by the drive into defined end positions relative to the support without the door remaining in an undesired intermediate position.

[0010] Further uses and advantages of the present invention are described below.

[0011] Usually, a door is connected to a support via two or more furniture hinges, which must be sturdy due to the large weight of the door. Therefore, the manufacturing of these furniture hinges for supporting the door is costly. Therefore, in order to reduce the cost, it may be specified that each of these furniture hinges is not equipped with its own energy storage device for moving the door.

[0012] Alternatively, at least one furniture hinge, preferably all furniture hinges provided for moving the door, can be implemented without a separate energy accumulator for driving the door, i.e. at least one door can be driven solely by a drive relative to the support.

[0013] In other words, the kinematics of the door are determined by the furniture hinges provided, which themselves do not have their own energy storage devices for driving the door, whereas the drive of the door relative to the support is preferably assumed exclusively by the drive, which may preferably be provided as the only drive for driving the door relative to the support.

[0014] Since the drive can form the only device for driving the door relative to the support, the drive can be constructed robustly and equipped with a powerful energy accumulator.

[0015] Furthermore, providing a furniture hinge without an inherent energy storage device offers the possibility that the door may also be suitable for touch latch applications.

[0016] The TouchLatch device allows the door to be pushed from its closed position to its open position. If the furniture hinges were equipped with their own energy storage devices, the TouchLatch device would have to overcome the obstructing closing force of the furniture hinges. Depending on the number of furniture hinges used, the TouchLatch device would need to be equipped with unnecessarily very powerful, expensive, and sometimes dangerous energy storage devices.

[0017] Alternatively, the furniture hinge provided for moving the door, preferably all furniture hinges provided for moving the door, can be implemented without a specific energy storage device for moving the door, so that the door can be ejected by a touch latch device with a relatively weak energy storage device. The customer or installer on site can decide at their own discretion whether an additional drive device for driving the door is provided.

[0018] Further details and advantages of the invention will be explained in detail in the following description of the drawings. [Brief explanation of the drawings]

[Figure 2b] 1b shows the furniture shown in FIG. 1b with the doors in different positions relative to each other. [Figure 3a] 10A and 10B are perspective and enlarged views showing guides attached to the side walls for movably supporting the support; [Figure 3b] 10A and 10B are perspective and enlarged views showing guides attached to the side walls for movably supporting the support; [Figure 4a] 1A and 1B are perspective and enlarged views of an assembly part to be attached to a support for supporting a furniture hinge and a drive unit; [Figure 4b] 1A and 1B are perspective and enlarged views of an assembly part to be attached to a support for supporting a furniture hinge and a drive unit; [Figure 5a] 1A-1C show a drive device arranged in an assembly part and a furniture hinge arranged in an assembly part in two different relative positions. [Figure 5b] 1A-1C show a drive device arranged in an assembly part and a furniture hinge arranged in an assembly part in two different relative positions. [Figure 6a] 1A and 1B are perspective views showing a drive device from two different viewpoints. [Figure 6b] 1A and 1B are perspective views showing a drive device from two different viewpoints. [Figure 7]FIG.

[0020] Figure 1a shows a perspective view of a piece of furniture 1 comprising a furniture cabinet 2 and doors 3a, 3b; 4a, 4b movable relative to the furniture cabinet 2. The doors 3a, 3b and 4a, 4b are movable by a guide system 5 between a first position in which the doors 3a, 3b; 4a, 4b are aligned substantially coplanar with one another, and a second position in which the doors 3a, 3b; 4a, 4b are aligned substantially parallel to one another.

[0021] Doors 3a, 3b can be pushed into a lateral storage pocket 8a of the furniture cabinet 2 in a second (parallel) position, while doors 4a, 4b can be pushed into another storage pocket 8b in a mutually parallel position.

[0022] The functional form is explained below for doors 3a and 3b, but the same explanation applies to doors 4a and 4b.

[0023] The guide system 5 includes a guide rail 7 having a longitudinal direction (L). A guide carriage 6 connectable to the second door 3b is supported so as to be able to run along the guide rail 7. The guide rail 7 extends substantially parallel to the end face of the furniture cabinet 2 in the assembled state.

[0024] Figure 1b shows furniture 1, in which doors 3a, 3b have been moved to mutually angled positions starting from the coplanar position shown in Figure 1a. First door 3a is pivotally supported on support 11 via two or more furniture hinges 10. Support 11 (together with doors 3a, 3b) can be pushed into lateral storage pockets 8a in the depth direction (Z).

[0025] 1b, the support 11 is in a transition position in which it is connected to the guide rail 7 in the longitudinal direction (L), allowing the guide carriage 6 to move back and forth between the guide rail 7 and the support 11. In the transition position shown, the support 11 is releasably locked to the guide rail 7. The lock between the guide rail 7 and the support 11 can be released by the entry of the guide carriage 6 into or onto the support 11.

[0026] The support 11 is in the form of an elongated pillar whose length corresponds to at least half the height of the doors 3a, 3b. The doors 3a, 3b are pivotally connected to each other about a vertical axis via at least one hinge 9. The second door 3b is supported by a guide carriage 6 so that it can move along a guide rail 7.

[0027] 2a shows the furniture 1 with doors 3a, 3b, which are now aligned parallel to one another. The support 11 has been released from the guide rail 7 by the entry of the guide carriage 6, and the support 11 (together with the guide carriage 6 and doors 3a, 3b) can be pushed into the storage pocket 8a in the depth direction (Z) of the furniture cabinet 2. The depth direction (Z) runs transversely, preferably substantially perpendicular to the longitudinal direction (L) of the guide rail 7.

[0028] Figure 2b shows the furniture 1 with doors 3a, 3b, which are now fully pushed into the storage pocket 8a, i.e., they can be moved by the guide system 5 from a first position shown in Figure 1a, in which the doors 3a, 3b are aligned substantially coplanar with one another, to a second position shown in Figure 2b, in which the doors 3a, 3b are aligned substantially parallel to one another and are accommodated inside the storage pocket 8a.

[0029] This makes it possible, for example, to completely cover the kitchen area 12 shown in Figures 2a and 2b, so that this kitchen area 12 can be visually separated from the rest of the living space.

[0030] In the illustrated embodiment, the storage pocket 8a is formed by a side wall 13a and a separating wall 13b spaced apart and parallel to the side wall 13a. The doors 3a, 3b can be pushed between the side wall 13a and the separating wall 13b in a parallel position.

[0031] 3a shows a side wall 13a of the furniture cabinet 2 and guides 14, 15 attached to the side wall 13a, preferably in the form of guide rails 14a, 15a for supporting the support body 11 so that it can be moved in the depth direction (Z) of the furniture cabinet 2. The guides 14, 15 are attached to the side wall 13a and spaced apart from each other in the height direction. In principle, however, it is sufficient to provide only one guide 14, 15 for supporting the support body 11.

[0032] The at least one guide 14, 15 has a longitudinal direction (L1) which extends transversely, preferably substantially perpendicularly, to the longitudinal direction (L) of the guide rail 7. An elongated support 11 bearing the furniture hinges 10 can travel along the at least one guide 14, 15, for example via at least one running roller (not shown), between a retracted end position and a retracted end position. In the illustrated embodiment, two or more, in this case five, furniture hinges 10 for pivotably supporting the door 3a are arranged on the support 11.

[0033] The guide system 5 may comprise at least one compensation device 16 for compensating for a tilting moment of the support 11 about the tilting axis due to a return moment. The compensation device 16 may comprise, for example, a scissor mechanism 16a and / or a rope arrangement (not shown).

[0034] According to one embodiment, the support 11 may be ejectable from the inserted end position in the direction of the removed end position, preferably by means of a releasably lockable ejection device 17.

[0035] At least one drive 18, separate from the furniture hinge 10, is arranged on the support 11, by means of which the door 3a, which is connected to the support 11 in the assembled state, can be driven relative to the support 11 between a first position and a second position, thereby preventing undefined intermediate positions of the door 3a relative to the support 11.

[0036] Preferably, it is provided that the drive 18 is coupled to the support 11 and to the door 3a in all operating positions of the door 3a. Alternatively, the drive 18 may be configured such that the drive 18 is releasably connectable to at least one door 3a.

[0037] At least one drive (not shown) other than the drive 18 may be provided for driving the support 11 along the at least one guide 14, 15, so that the support 11 (and thus at least one door 3a) can be driven by the other drive at least in certain sections between the extended and extended end positions. Preferably, the drive provided for driving the support 11 functions exclusively mechanically, i.e. without electrical drive and without any additional electrical components.

[0038] FIG. 3b shows an enlarged view of the boxed area in FIG. 3a.

[0039] 4a shows an assembly part 19 for supporting the furniture hinge 10 and for supporting the drive 18. The assembly part 19 can be configured, for example, as a longitudinally extending profile rail which can be releasably coupled to the support body 11.

[0040] In a first assembly step, the furniture hinge 10 and the drive 18 are pre-assembled to an assembly part 19. In a subsequent assembly step, the assembly part 19 (together with the pre-assembled components) is coupled to the support 11. Preferably, the assembly part 19 can be coupled to the support 11 in a direction extending transversely to the longitudinal direction of the support 11.

[0041] Figure 4b shows an enlarged view of the boxed area in Figure 4a. The mounting part 19 may be formed as an elongated profile rail with a substantially U-shaped or L-shaped cross section. The mounting part 19 may have a first web 19a for bearing against the support 11 and at least one second web 19b projecting from the first web 19a, preferably at a substantially right angle.

[0042] At least one furniture hinge 10 for movably supporting the door 3a and at least one drive device 18 for driving the door 3a are arranged in the mounting part 19.

[0043] The furniture hinge 10 includes a first hardware body 10a for attachment to the mounting part 19 and a second hardware body 10b for attachment to the door 3a. The first hardware body 10a and the second hardware body 10b are pivotally connected to each other. The second hardware body 10b of the furniture hinge 10 is provided with at least one attachment point 10c for attaching the door 3a. The at least one attachment point 10c may be configured as, for example, a hole, a dowel, or a locking element.

[0044] The second hardware body 10b of the furniture hinge 10 has a flat abutment surface 10d for abutting against the door 3a. The first hardware body 10a and the second hardware body 10b are movable relative to each other between a first position and a second position. In the first position, the abutment surface 10d of the second hardware body 10b is positioned substantially parallel to the first web 19a of the mounting portion 19 (i.e., approximately perpendicular to the side wall 13a of the furniture cabinet 2). In the second position, the abutment surface 10d of the second hardware body 10b is positioned substantially perpendicular to the first web 19a of the mounting portion 19 (i.e., approximately parallel to the side wall 13a of the furniture cabinet 2).

[0045] The drive 18, which is separate from the furniture hinge 10 and drives the door 3a relative to the support 11, includes a first metal part 18a for attachment to the support 11 or to an assembly part 19 and a second metal part 18b for attachment to the door 3a. The first metal part 18a and the second metal part 18b of the drive 18 are pivotally connected to each other. The second metal part 18b of the drive 18 is provided with at least one attachment point 18c for attaching the door 3a. The at least one attachment point 18c can be configured, for example, as a hole, a dowel, or a locking element.

[0046] The second metal part 18b of the drive unit 18 has a flat abutment surface 18d for abutting against the door 3a. The first metal part 18a and the second metal part 18b of the drive unit 18 are movable relative to each other between a first position and a second position. In the first position, the abutment surface 18d of the second metal part 18b is positioned substantially parallel to the first web 19a of the mounting part 19 (i.e., approximately perpendicular to the side wall 13a of the furniture cabinet 2). In the second position, the abutment surface 18d of the second metal part 18b is positioned substantially perpendicular to the first web 19a of the mounting part 19 (i.e., approximately parallel to the side wall 13a of the furniture cabinet 2).

[0047] Figure 5a shows a drive 18 arranged in an assembly part 19 and a furniture hinge 10 arranged in the assembly part 19. In the shown view, the abutment surface 18d of the second fitting part 18b of the drive 18 is positioned such that in the mounted state the door 3a, which is connected to the second fitting part 18b, is positioned approximately perpendicular to the side wall 13a of the furniture cabinet 2. This position of the abutment surface 18d corresponds to the coplanar position of the furniture parts 3a, 3b relative to one another (Figure 1a).

[0048] Figure 5b shows the assembly shown in Figure 5a in another relative position of the drive 18 and the furniture hinge 10. The abutment surface 18d of the second fitting part 18b of the drive 18 is positioned such that in the assembled state the door 3a, which is coupled to the second fitting part 18b, is aligned substantially parallel to the side wall 13a of the furniture cabinet 2. This position of the abutment surface 18d therefore corresponds to the position of the furniture parts 3a, 3b, which are parallel to each other (Figure 2a).

[0049] In the illustrated embodiment, it is provided that the first metal part 18a and the second metal part 18b of the drive device 18 are pivotally connected to each other via at least two levers 20a, 20b pivotally connected to each other.

[0050] The drive device 18 may have at least one energy accumulator 21, by means of which the first fitting part 18a and the second fitting part 18b can be driven into a first position and / or a second position relative to each other. The energy accumulator 21 may, for example, comprise at least one coil spring, preferably at least one compression spring.

[0051] The drive unit 18 has at least one first pivot axis (A), whereas the furniture hinge 10 has at least one second pivot axis (A1). The first pivot axis (A) of the drive unit 18 and the second pivot axis (A1) of the furniture hinge 10 extend coaxially with each other when assembled to the support 11, and the first pivot axis (A) and the second pivot axis (A1) each extend vertically.

[0052] Preferably, it is provided that the at least one door 3a can be driven exclusively by the drive device 18, and that the at least one furniture hinge 10 itself does not have its own energy storage device for driving the at least one door 3a.
