Description

[Technical Field]

[0001] The present invention relates to a guide system for guiding at least one movably supported door, in particular a folding sliding door, along a furniture wall, comprising: - at least one support for pivotally supporting at least one door; - at least one guide, in particular a guide rail, to be attached to the furniture wall for moving at least one support along the furniture wall; at least one guide device for supporting at least one support body slidably along at least one guide; - at least one rack and at least one gear that meshes or can mesh with the rack, the gear being movable at least partially along the rack and being rotated by meshing with the rack when the support moves along the guide, Regarding guide systems.

[0002] The invention further relates to a piece of furniture comprising a furniture cabinet, at least one door, in particular a folding sliding door, supported so as to be movable relative to the furniture cabinet, and at least one guide system of the described type for moving the at least one door relative to the furniture cabinet.

[0003] U.S. Patent Application Publication No. 2004 / 0046488 discloses a guide system for a door, which allows the door to move along the side wall of a furniture cabinet. That is, the door can be pushed in the depth direction of the furniture, and in the pushed-in position, the door releases its path into the interior of the furniture cabinet. The door is pivotably supported on a support via a hinge, and the support is movable along the side wall of the furniture cabinet via a number of racks spaced apart in the height direction and a number of gears that mesh with the racks. A synchronizing shaft allows the rotational movement of the gears to be synchronized with each other. A drawback of this structure is that the guide system is only suitable for lightweight doors. A challenge when guiding a door along a furniture wall is that the door tends to tilt due to its weight. This subsequently causes undesirable twisting of the support and jamming of the door relative to the guide. Furthermore, due to the weight of the door, the upper gear may no longer mesh properly with the upper rack corresponding to it, while the lower gear may get caught on the lower rack due to the weight of the door. This situation makes it impossible, or at least extremely difficult, for the door to move. Furthermore, this may cause undesirable running noise, especially if all the racks are mounted flush on the side walls. In this configuration, the furniture cabinet may become a resonator due to the vibrations generated, which may further increase the noise.

[0004] SUMMARY OF THE INVENTION 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.

[0005] This problem is solved according to the invention by the features of claim 1. Further advantageous embodiments of the invention are described in the dependent claims.

[0006] According to the invention, it is specified that the at least one support comprises at least one support device for supporting at least one rack.

[0007] In other words, at least one rack is supported on a support, and at least one door can be pivoted on the support, and the door can move along at least one guide arranged on the furniture wall in the assembled position. This ensures that the at least one gear has a defined distance relative to the at least one rack, and that the gear always moves relative to the rack with a predetermined meshing depth. Furthermore, this can reduce unpleasant running noise.

[0008] According to an embodiment, it may be specified that the at least one support device and the at least one rack are movable relative to one another, preferably slidable relative to one another.

[0009] According to a preferred embodiment, it may be specified that the at least one support device comprises at least one linear guide, preferably a U-shaped member, for movably, preferably slidably supporting the at least one rack.

[0010] The at least one linear guide can limit the depth of engagement of the at least one gear such that the teeth of the at least one gear only partially intermesh between the teeth of the at least one rack, thereby limiting the depth of engagement of the at least one gear such that the at least one gear is prevented from becoming entangled or disengaged relative to the at least one rack.

[0011] Further details and advantages of the invention will become apparent from the following description of the drawings. [Brief explanation of the drawings]

[Figure 8a] FIG. 2 is a perspective view showing the support device together with a rack supported by the support device. [Figure 8b] FIG. 8b is an enlarged detail of FIG. 8a. [Figure 9] FIG. 1 is a side view of the furniture wall with the door fully extended. [Figure 10a] FIG. 1 shows the (upper) first support device engaged with the (upper) first rack. [Figure 10b] FIG. 10 shows the (lower) second support device engaging with the (lower) second rack.

[0013] 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. 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.

[0014] Doors 3a, 3b can be pushed into a lateral storage pocket 8a of 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.

[0015] Below, the functional form is explained for doors 3a and 3b, but the same explanation applies to doors 4a, 4b.

[0016] The guide system 5 includes a guide rail 7 having a longitudinal direction (L), and 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.

[0017] Figure 1b shows furniture 1 in which doors 3a, 3b have been moved out of the coplanar position shown in Figure 1a and into a position at an angle to one another. A first door 3a is pivotally supported via two or more hinges 10 on a support 11, which (together with doors 3a, 3b) can be pushed into a lateral storage pocket 8a in the depth direction Z.

[0018] 1b, the support 11 is in a transfer position in which it is connected to the guide rail 7 in the longitudinal direction L, so that the guide carriage 6 can be moved back and forth between the guide rail 7 and the support 11. In the transfer position shown, the support 11 is releasably locked to the guide rail 7, and 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.

[0019] The support 11 is in the form of an elongated pillar having a length corresponding 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 movably along a guide rail 7 via a guide carriage 6.

[0020] 2a shows furniture 1 with doors 3a, 3b that are currently aligned parallel to one another. Support body 11 is unlocked from guide rail 7 by the entry of guide carriage 6, and support body 11 (together with guide carriage 6 and doors 3a, 3b) can be pushed into storage pocket 8a in depth direction Z of furniture cabinet 2. Depth direction Z extends transversely, preferably substantially perpendicularly, to longitudinal direction L of guide rail 7.

[0021] Figure 2b shows the furniture 1 with the doors 3a, 3b currently fully pushed into the storage pocket 8a, i.e. the doors 3a, 3b are movable 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 housed within the storage pocket 8a.

[0022] In this way, for example, the kitchen 12 shown in Figures 2a and 2b can be completely covered, thereby separating this kitchen 12 from the rest of the living space.

[0023] In the illustrated embodiment, the storage pocket 8a is formed by a first furniture wall 13a and a second furniture wall 13b arranged substantially parallel to and spaced apart from the first furniture wall 13a, and the doors 3a, 3b can be pushed between the furniture walls 13a, 13b in a parallel position to each other. In the illustrated embodiment, the furniture walls 13a, 13b are each formed as side walls of the furniture cabinet 2.

[0024] 3 shows a perspective view of a furniture wall 13a with a guide system 5 for guiding at least one door 3a. For clarity, the second door 3b pivotally connected to the first door 3a is not shown.

[0025] The guide system 5 comprises at least one elongated support 11 on which at least one door 3a can be pivotably supported, for example via two or more hinges 10. The support 11 can have a length that corresponds substantially to the height of the door 3a.

[0026] The guide system 5 comprises at least one guide 14, preferably a guide rail 14a, to be attached to the furniture wall 13a for moving the at least one support 11 along the furniture wall 13a.

[0027] In the illustrated embodiment, further guides 15, 16, preferably further guide rails 15a, 16a, are provided, which allow the at least one support 11 to move along the furniture wall 13a. The guides 14, 15, 16 are mounted on the furniture wall 13a at a vertical distance from one another.

[0028] The support 11 is movable along the at least one guide 14 via the at least one guide device 21. The guide device 21 may have at least one pulley 21a (FIG. 4), preferably a plurality of pulleys 21a, which are rollable along the at least one guide 14.

[0029] The guide device 21 may have a plurality of pulleys 21a supported rotatably about a rotation axis oriented in a first direction, and may further include another pulley supported rotatably about a rotation axis oriented in a second direction.

[0030] The guide system 5 has at least one rack 19a, and at least one gear 24a (Figure 4) is movable along the at least one rack 19a as the support 11 moves along the at least one guide 14.

[0031] In the illustrated embodiment, at least one second rack 19b is provided, and at least one second gear 24b (FIG. 4) is movable along the second rack 19b as the support 11 moves along the guides 14, 15, 16.

[0032] According to the invention, it is specified that the support 11 comprises at least one support device 18a, 18b for supporting at least one rack 19a, 19b.

[0033] The racks 19a, 19b have end regions and are provided with at least one holding device 20a, 20b that can be attached to the furniture wall 13a, on which the end regions of the racks 19a, 19b are supported.

[0034] The holding devices 20a, 20b have at least one mounting point 22a, 22b by means of which the end regions of the racks 19a, 19b can be fastened to the furniture wall 13a. The mounting points 22a, 22b of the holding devices 20a, 20b may, for example, comprise holes for passing through screws and / or at least one dowel for attachment to the furniture wall 13a.

[0035] The holding devices 20a and 20b have guides 23a and 23b, respectively, for movably supporting the racks 19a and 19b. In other words, the racks 19a and 19b are supported so as to be slidable relative to the holding devices 20a and 20b.

[0036] At least one gear 24a, 24b (FIG. 4) for rolling along the racks 19a, 19b may be rotatably arranged, for example, on the support 11 or on at least one support device 18a, 18b of the support 11.

[0037] Figure 4 shows another perspective view of the furniture wall 13a with the guide system 5 according to Figure 3. Both support devices 18a, 18b of the support body 11 can be seen, on which or in which at least one gear wheel 24a, 24b is rotatably supported, respectively, or on the support body 11. The at least one gear wheel 24a, 24b may be rotatably supported about an axis extending parallel to the longitudinal direction E of the support body 11 and is configured to mesh with at least one rack 19a, 19b.

[0038] To synchronize the rotational movements of the gears 24a, 24b, at least one synchronizing rod 25 is provided, which extends substantially parallel to the longitudinal direction E of the support 11. The rotational movements of the gears 24a, 24b can thus be synchronized with one another by the rotational movement of the synchronizing rod 25 about its own axis.

[0039] In the illustrated embodiment, at least one stabilizing device 26 is provided, which can prevent or at least limit bending of the synchronization rod 25 in a direction extending transverse to the longitudinal direction E of the synchronization rod 25.

[0040] The at least one stabilizing device 26 may be arranged in a central region of the synchronization rod 25 and / or may have at least one opening 27 for the synchronization rod 25 to pass through.

[0041] 5a to 5c each show an enlarged detailed view of FIG.

[0042] Figure 5a shows an enlarged view of the boxed area "A" according to Figure 4. A support device 18a attached to the support 11 for movably supporting a rack 19a can be seen. The support device 18a has at least one rotatable gear 24a meshing with the rack 19a.

[0043] The support device 18a may have at least one linear guide 28 for movably supporting the rack 19a. The support device 18a is supported so as to be movable relative to the rack 19a when the support 11 moves along the guide 14. In the illustrated embodiment, the at least one linear guide 28 has a U-shaped member that can guide the rack 19a.

[0044] Figure 5b shows an enlarged view of the boxed area "B" according to Figure 4. A stabilizing device 26 can be seen which can prevent or at least limit bending of the synchronization rod 25 in a direction extending transversely to the longitudinal direction E of the synchronization rod 25.

[0045] In the illustrated embodiment, the stabilizing device 26 has an attachment section 26a for bearing against the support 11 and a retaining web 26b projecting laterally, preferably perpendicularly, from the attachment section 26a for retaining the synchronizing rod 25. The attachment section 26a has at least one attachment point 26c through which the stabilizing device 26 can be attached to the support 11. The retaining web 26b has at least one, for example cylindrical, opening 27 for the synchronization rod 25 to pass through.

[0046] Figure 5c shows an enlarged view of the boxed area "C" according to Figure 4. The lower second support device 18b has at least one second gear 24b that can roll along a second rack 19b. The rotational movements of both gears 24a, 24b can be synchronized with one another by at least one synchronizing rod 25. The second support device 18b also has a linear guide 28, preferably U-shaped, for receiving and guiding the second rack 19b.

[0047] Figure 6 shows the guide system 5 in another perspective view, which is shown in a position in which the door 3a is completely inside the storage pocket 8a (corresponding to the position shown in Figure 2b). For clarity, the door 3a has been omitted.

[0048] The racks 19a, 19b each have a first end region and a second end region, the first end regions of the racks 19a, 19b are supported by first holding devices 20a, 20b and the second end regions of the racks 19a, 19b are supported by second holding devices 20c, 20d, the holding devices 20a, 20b, 20c, 20d can each be attached to the furniture wall 13a, and the support devices 18a, 18b are movable between the two holding devices 20a, 20b, 20c, 20d.

[0049] In other words, the end regions of the racks 19a, 19b are supported by respective holding devices 20a, 20b, 20c, 20d, which can be attached to the furniture wall 13a.

[0050] The retaining devices 20a, 20b, 20c, 20d are preferably configured to retain at least one rack 19a, 19b in a spaced relation to the furniture wall 13a when the retaining devices 20a, 20b, 20c, 20d are attached.

[0051] Therefore, the support devices 18a, 18b can move between the holding devices 20a, 20b, 20c, 20d, and the racks 19a, 19b are spaced apart from the furniture wall 13a. In this way, the relative distance between the gears 24a, 24b and the racks 19a, 19b can be kept constant, and the gears 24a, 24b can move along the racks 19a, 19b with a constant meshing depth at all times.

[0052] Figure 7a shows in a perspective view from the front the guide system 5. Guides 15, 16 can be seen, preferably in the form of guide rails 15a, 16a, along which the support 11, together with the hinge 10 for movably supporting the door 3a, is movable in the assembled position.

[0053] The rack 19a can be attached at one end region to the furniture wall 13a via a holding device 20a, and at the other end of the rack 19a can be attached to the furniture wall 13a in the same way via a holding device 20c (Figure 6). The support device 18a of the support body 11 is movable along the rack 19a between the two holding devices 20a, 20c.

[0054] To compensate for position errors between the (upper) first rack 19a and the (lower) second rack 19b, at least one adjustment device 29 is provided, by means of which the position of the rack 19a relative to the at least one holding device 20a, 20c can be adjusted.

[0055] The adjustment device 29 may, for example, have at least one rotatable adjustment wheel 29a, and the position of the rack 19a relative to the holding device 20a is adjustable by rotating the at least one adjustment wheel 29a.

[0056] That is to say, by means of the adjustment device 29, an erroneous position, in particular a tilt, of at least one door 3a can be corrected, the erroneous position being caused by a twist of the support 11 and / or by the weight of the door 3a.

[0057] In other words, the adjustment device 29 allows the position of the support 11 relative to the rack 19a to be adjusted, allowing mobility between the rack 19a and the holding devices 20a, 20c which can be attached to the furniture wall 13a.

[0058] According to an embodiment, it may be specified that the front end of the rack 19a is kinematically connected to an adjustment element 29a of the holding device 20c, while the rear end of the rack 19a is guided so as to slide in a guide 23a (FIG. 4) of the holding device 20a.

[0059] Figure 7b shows an enlarged view of the boxed area "A" in Figure 7a. An adjusting wheel 29a is rotatably supported on the front holding device 20c. By rotating the adjusting wheel 29a, the position of the rack 19a relative to the holding devices 20a, 20c can be adjusted. A linear guide 28 of the supporting device 18a can be seen for movably supporting the rack 19a.

[0060] At least one sliding device 30 may be provided, which can reduce the frictional resistance between the at least one support device 18a, 18b and the at least one rack 19a, 19b. The at least one sliding device 30 may, for example, have a rolling element 30a which is rotatable about an axis which, in the assembled position, preferably extends vertically.

[0061] The tilt caused by the weight of at least the door 3a can push the side of the rack 19a opposite to the teeth provided on the rack 19a towards the support device 18a, for this reason the sliding device 30 is provided to reduce the friction resistance between the rack 19a and the support device 18a.

[0062] At least one adjusting wheel 29a of the adjusting device 29 may be designed for manual operation and / or may be directly accessible by a person from the front in the assembled state of the guide system 5.

[0063] FIG. 8a shows a perspective view of the rack 19a together with both holding devices 20a, 20c for attachment to the furniture wall 13a and a support device 18a for supporting the rack 19a movably along it.

[0064] The holding devices 20a, 20c which can be attached to the furniture wall 13a each have one guide 23a for movably supporting the rack 19a.

[0065] Figure 8b shows an enlarged view of the boxed area in Figure 8a. At least one gear 24a is rotatably supported on the support device 18a, and the gear 24a is movable along the rack 19a.

[0066] The at least one rack 19a has a first longitudinal surface 31a with a row of teeth that mesh or can mesh with the at least one gear 24a. The rack 19a further has a second longitudinal surface 31b opposite the first longitudinal surface 31a, and the at least one sliding device 30 can abut against the second longitudinal surface 31b of the rack 19a.

[0067] The sliding device 30 for reducing frictional resistance between the rack 19a and the support device 18a may have at least one rolling element 30a that can come into contact with the second longitudinal surface 31b of the rack 19a.

[0068] In the illustrated embodiment, the sliding device 30 has a plurality of rolling elements 30a which are spaced apart from one another in the longitudinal direction of the rack 19a and / or which are arranged in at least two rolling planes which are positioned above one another in the assembled position.

[0069] 9 shows the furniture wall 13a in a side view with the door 3a fully extended. The assembly consisting of the racks 19a, 19b, the gears 24a, 24b, the support devices 18a, 18b and, if necessary, the synchronization rod 25 together form a compensation device for compensating by a return moment 33 the tilting moment 32 of the support 11 about the tilting axis 34 or of the door 3a arranged on the support.

[0070] When the support 11 or the door 3a is oriented vertically, the tilting axis 34 is oriented horizontally, i.e. the compensating device including the components described above ensures that at least one door 3a is stably guided in any position without excessive tilting of the door 3a relative to the guides 14, 15, 16.

[0071] FIG. 10a shows the (upper) first support device 18a meshing with the upper first rack 19a. A gear 24a is rotatably supported on the support device 18a. The support device 18a is arranged on a support 11, and the door 3a is pivotally supported on the support 11 via a hinge 10. This means that the gear 24a is pulled in direction M1 by the weight of the door 3a. That is, the tooth flank 17 of the gear 24a presses against the teeth of the rack 19a in direction M1. The cooperation of the oblique tooth flank 17 of the gear 24a and the oblique tooth row of the rack 19a results in a force pressing the second longitudinal surface 31b (see FIG. 8b) of the rack 19a, opposite to the first longitudinal surface 31a, against the sliding device 30 including the rolling elements 30a. That is, the sliding device 30 is provided to reduce the friction resistance between the second longitudinal surface 31b of the rack 19a and the upper support device 18.

[0072] In contrast, Figure 10b shows the (lower) second support device 18b meshing with the (lower) second rack 19b. A second gear 24b is rotatably supported on the support device 18b. The second support device 18b is arranged on the support 11 at a distance from the first support device 18a, and the door 3a is pivotally supported on the support 11 via the hinge 10. This means that the second gear 24b of the (lower) second support device 18b is pushed in direction M2 by the weight of the door 3a. In other words, the tooth flank 17 of the second gear 24b pushes against the teeth of the second rack 19b in direction M2. Cooperation between the oblique tooth flank 17 of the second gear 24b and the oblique tooth row of the second rack 19b results in a force that presses the longitudinal surface 31b of the second rack 19b opposite to the first longitudinal surface 31a against the second sliding device 30 including the rolling elements 30a. In other words, the second sliding device 30 is provided to reduce frictional resistance between the longitudinal surface 31b of the second rack 19b and the (lower) second support device 18b.
