AI Technical Summary
Existing guide systems for movably mounted door leaves, particularly folding-sliding doors, face issues with door leaf tilting due to weight, leading to undesirable torsion, jamming, and increased noise, as they are not suitable for heavy doors and can cause resonance in furniture bodies.
The guide system incorporates a carrier with a storage device that supports the rack, allowing for a defined engagement depth of the gear with the rack, and includes a linear guide, such as a U-profile, to prevent jamming and reduce noise by limiting the gear's engagement depth and using sliding devices to reduce frictional resistance.
This solution stabilizes the door leaf movement, prevents jamming, and reduces noise by maintaining a consistent gear engagement and minimizing friction, ensuring smooth operation even with heavier door leaves.

Description
[0001] Guide system for guiding at least one movably mounted
[0002] door leaf
[0003] The present invention relates to a guide system for guiding at least one movably mounted door leaf, in particular a folding-sliding door, along a furniture wall, comprising:
[0004] - at least one support for pivotally supporting the at least one door leaf,
[0005] - at least one guide to be attached to the furniture wall, in particular a guide rail, for moving the at least one support along the furniture wall,
[0006] - at least one guide device for displaceably supporting the at least one carrier along the at least one guide,
[0007] - at least one toothed rack and at least one gear wheel engaging or engageable with the toothed rack, wherein the gear wheel can be moved at least in sections along the toothed rack when the carrier moves along the guide and can be set in rotation by engaging with the toothed rack.
[0008] Furthermore, the invention relates to a piece of furniture with a furniture body, at least one door leaf mounted so as to be movable relative to the furniture body, in particular a folding-sliding door, and with at least one guide system of the type to be described for moving the at least one door leaf relative to the furniture body.
[0009] US 2004 / 0046488 A1 shows a guide system for a door leaf which can be moved along a side wall of the furniture body by means of the guide system. The door leaf can therefore be pushed in in a depth direction of the furniture, with the door leaf in the pushed-in position providing access to the interior of the furniture body. The door leaf is pivotally mounted on a support via hinges, with the support being movable along the side wall of the furniture body via a plurality of toothed racks spaced apart from one another in the vertical direction and via a plurality of gears engaging with the toothed racks. The rotary movements of the gears can be synchronized with one another by means of a synchronization shaft. A disadvantage of this design is that the guide system is only suitable for lightweight door leaves.The challenge when guiding a door leaf along a furniture wall is that the door leaf has a tendency to tilt due to its weight. This subsequently leads to undesirable torsion of the support and to wedging of the door leaf relative to the guide. It is also possible that the upper gears no longer mesh properly with their assigned upper racks due to the weight of the door leaf, while the lower gears can become jammed in the lower rack due to the acting weight of the door leaf. These circumstances make it impossible or at least significantly more difficult for the door leaf to move. This can also lead to undesirable running noises, particularly since all the racks are attached flat to the side wall. In this way, it is possible that the furniture body becomes a resonator due to the vibrations that occur, thereby amplifying the noise even further.
[0010] The object of the present invention is to provide a guidance system of the type mentioned at the outset while avoiding the disadvantages discussed above.
[0011] This is achieved according to the invention by the features of patent claim 1. Further advantageous embodiments of the invention are specified in the dependent claims.
[0012] According to the invention, it is provided that the at least one carrier has at least one bearing device for supporting the at least one toothed rack.
[0013] In other words, the at least one toothed rack is mounted on the support, on which the at least one door leaf can be pivotally arranged and which, in an assembled position, can be moved along at least one guide arranged on the furniture wall. This ensures that the at least one gear wheel has a defined distance relative to the at least one toothed rack, wherein the gear wheel is always moved relative to the toothed rack with a predetermined engagement depth. In addition, annoying running noises can be reduced in this way. According to one exemplary embodiment, it can be provided that the at least one bearing device and the at least one toothed rack are movable relative to one another, preferably displaceable relative to one another.
[0014] According to a preferred embodiment, it can be provided that the at least one bearing device has at least one linear guide, preferably a U-profile, for the movable, preferably displaceable, mounting of the at least one toothed rack.
[0015] The at least one linear guide allows the engagement depth of the at least one gear to be limited such that the teeth of the at least one gear only partially engage the tooth gaps of the at least one rack. In this way, the engagement depth of the at least one gear can be limited such that jamming or disengagement of the at least one gear relative to the at least one rack is prevented.

[0030] Fig. 1a shows a perspective view of a piece of furniture 1 with a furniture body 2 and door leaves 3a, 3b; 4a, 4b that can be moved relative thereto. The door leaves 3a, 3b and the door leaves 4a, 4b can be moved by a guide system 5 between a first position, in which the door leaves 3a, 3b; 4a, 4b are aligned substantially coplanar to one another, and a second position, in which the door leaves 3a, 3b; 4a, 4b are aligned substantially parallel to one another.
[0031] The door leaves 3a, 3b can be inserted into a lateral receiving compartment 8a of the furniture body 2 in a second (parallel) position, while the door leaves 4a, 4b can be inserted into a further receiving compartment 8b in a parallel position to one another.
[0032] The mode of operation is explained below using the door leaves 3a and 3b, whereby the same explanations apply to the door leaves 4a, 4b.
[0033] The guide system 5 comprises a guide rail 7 with a longitudinal direction (L), wherein a guide carriage 6 which can be connected to the second door leaf 3b is mounted so as to be movable along the guide rail 7. In the assembled state, the guide rail 7 runs essentially parallel to the front side of the furniture body 2. Fig. 1b shows the piece of furniture 1, wherein the door leaves 3a, 3b have been moved from the coplanar position shown in Fig. 1a into an angular position to one another. The first door leaf 3a is pivotally mounted on a support 11 via two or more hinges 10, wherein the support 11 (together with the door leaves 3a, 3b) can be pushed into the lateral receiving compartment 8a in a depth direction Z.
[0034] In Fig. 1b, the carrier 11 is in a transfer position in which the carrier 11 adjoins the guide rail 7 in the longitudinal direction L, so that the guide carriage 6 can be transferred back and forth between the guide rail 7 and the carrier 11. In the transfer position shown, the carrier 11 is releasably locked to the guide rail 7, wherein the locking between the guide rail 7 and the carrier 11 can be released by the guide carriage 6 entering or onto the carrier 11.
[0035] The support 11 is designed in the form of an elongated column, the length of which corresponds to at least half the height of the door leaves 3a, 3b. The two door leaves 3a, 3b are connected to one another in an articulated manner about a vertically extending axis via at least one hinge fitting 9. The second door leaf 3b is mounted so as to be movable along the guide rail 7 via the guide carriage 6.
[0036] Fig. 2a shows the piece of furniture 1 with the door leaves 3a and 3b, which are now aligned parallel to one another. The support 11 has been unlocked by the guide carriage 6 entering the guide rail 7, whereby the support 11 (together with the guide carriage 6 and the door leaves 3a, 3b) can be pushed into the receiving compartment 8a in the depth direction Z of the furniture body 2. The depth direction Z runs transversely, preferably substantially at right angles, to the longitudinal direction L of the guide rail 7.
[0037] Fig. 2b shows the furniture 1 with the door leaves 3a, 3b, which are now in a fully inserted state in the receiving compartment 8a. The door leaves 3a, 3b are thus guided by the guide system 5 from a first position according to Fig. 1a, in which the door leaves 3a, 3b are in
[0038] are aligned substantially coplanar to one another, and a second position according to Fig. 2b, in which the door leaves 3a, 3b are aligned substantially parallel to one another and are accommodated within the receiving compartment 8a.
[0039] In this way, for example, a kitchen 12 as shown in Figures 2a, 2b can be completely covered so that the kitchen 12 can be separated from the remaining area of a living space.
[0040] In the illustrated embodiment, the receiving compartment 8a is formed by a first furniture wall 13a and a second furniture wall 13b spaced substantially parallel to the first furniture wall 13a, wherein the door leaves 3a, 3b can be inserted in a parallel position between the two furniture walls 13a, 13b. In the illustrated embodiment, the two furniture walls 13a, 13b are each designed as side walls of the furniture body 2.
[0041] Fig. 3 shows a perspective view of the furniture wall 13a with the guide system 5 for guiding at least one door leaf 3a. For reasons of clarity, the second door leaf 3b, which is pivotally connected to the first door leaf 3a, is not shown.
[0042] The guide system 5 comprises at least one elongated support 11, on which the at least one door leaf 3a can be pivotally mounted, for example via two or more hinges 10. The support 11 can have a length that essentially corresponds to a height of the door leaf 3a.
[0043] The guide system 5 comprises at least one guide 14 to be fastened to the furniture wall 13a, preferably a guide rail 14a, for moving the at least one support 11 along the furniture wall 13a.
[0044] In the exemplary embodiment shown, further guides 15, 16, preferably further guide rails 15a, 16a, are provided, by means of which the at least one support 11 can be moved along the furniture wall 13a. The guides 14, 15, 16 are fastened to the furniture wall 13a at a vertical distance from one another. The support 11 can be moved along the at least one guide 14 via at least one guide device 21. The guide device 21 can have at least one roller 21a (Fig. 4), preferably a plurality of rollers 21a, which can roll along the at least one guide 14.
[0045] The guide device 21 can have a plurality of rollers 21a, which are mounted for rotation about a rotation axis oriented in a first direction. Furthermore, further rollers can be provided, which are mounted for rotation about a rotation axis oriented in a second direction.
[0046] The guide system 5 has at least one rack 19a, wherein at least one gear wheel 24a (Fig. 4) can be moved on the at least one rack 19a when the carrier 11 moves along the at least one guide 14.
[0047] In the embodiment shown, at least one second rack 19b is provided, wherein at least one second gear 24b (Fig. 4) is movable on the second rack 19b when the carrier 11 moves along the guides 14, 15, 16.
[0048] According to the invention, it is provided that the carrier 11 has at least one bearing device 18a, 18b for supporting the at least one rack 19a, 19b.
[0049] The rack 19a, 19b has an end region, wherein at least one holding device 20a, 20b is provided to be fastened to the furniture wall 13a, on which the end region of the rack 19a, 19b is mounted.
[0050] The holding device 20a, 20b has at least one fastening point 22a, 22b, by means of which an end region of the rack 19a, 19b can be fixed to the furniture wall 13a. The fastening point 22a, 22b of the holding device 20a, 20b can, for example, comprise a hole for the passage of a screw and / or at least one dowel for fastening to the furniture wall 13a. The holding devices 20a, 20b each have a guide 23a, 23b for the movably mounting of the rack 19a, 19b. In other words, the rack 19a, 19b is mounted displaceably relative to the holding device 20a, 20b.
[0051] The at least one gear wheel 24a, 24b (Fig. 4) for running on the rack 19a, 19b can be rotatably arranged, for example, on the carrier 11 or on the at least one bearing device 18a, 18b of the carrier 11.
[0052] Fig. 4 shows a further perspective view of the furniture wall 13a with the guide system 5 according to Fig. 3. The two bearing devices 18a, 18b of the support 11 can be seen, wherein at least one gear 24a, 24b is rotatably mounted on or in the bearing devices 18a, 18b or on the support 11. The at least one gear 24a, 24b can be rotatably mounted about an axis running parallel to the longitudinal direction E of the support 11 and is designed to mesh with the at least one rack 19a, 19b.
[0053] To synchronize a rotational movement of the gears 24a, 24b, at least one synchronization rod 25 is provided, which extends substantially parallel to the longitudinal direction E of the carrier 11. Thus, a rotational movement of the gears 24a, 24b relative to one another can be synchronized by a rotational movement of the synchronization rod 25 about its own axis.
[0054] In the embodiment shown, at least one stabilizing device 26 is provided, by means of which buckling of the synchronization rod 25 in a direction running transversely to the longitudinal direction E of the synchronization rod 25 can be prevented or at least limited.
[0055] The at least one stabilizing device 26 can be arranged in a central region of the synchronization rod 25 and / or can have at least one opening 27 for the passage of the synchronization rod 25. Figures 5a-5c each show enlarged detailed views of Fig. 4.
[0056] Fig. 5a shows the framed area "A" according to Fig. 4 in an enlarged view. The bearing device 18a fastened to the carrier 11 for the movable mounting of the rack 19a can be seen. The bearing device 18a has at least one rotatable gear 24a which meshes with the rack 19a.
[0057] The bearing device 18a can have at least one linear guide 28 for movably supporting the rack 19a. The bearing device 18a is movably mounted relative to the rack 19a when the carrier 11 moves along the guide 14. In the illustrated embodiment, the at least one linear guide 28 has a U-profile in which the rack 19a can be guided.
[0058] Fig. 5b shows the framed area "B" according to Fig. 4 in an enlarged view. The stabilizing device 26 can be seen, by means of which a buckling of the synchronization rod 25 in a direction running transversely to the longitudinal direction E of the synchronization rod 25 can be prevented or at least limited.
[0059] In the illustrated embodiment, the stabilizing device 26 has a fastening section 26a for engagement with the carrier 11 and a holding web 26b projecting transversely, preferably at a right angle, from the fastening section 26a for holding the synchronization rod 25. The fastening section 26a has at least one fastening point 26c through which the stabilizing device 26 can be fastened to the carrier 11. The holding web 26b has at least one opening 27, for example a cylindrical opening, for the passage of the synchronization rod 25.
[0060] Fig. 5c shows the framed area "C" according to Fig. 4 in an enlarged view. The lower, second bearing device 18b has at least one second gear 24b, which can roll on the second rack 19b. The rotational movements of the two gears 24a, 24b can be synchronized with one another by the at least one synchronization rod 25. The second bearing device 18b also has a linear guide 28, preferably a U-profile, for receiving and guiding the second rack 19b.
[0061] Fig. 6 shows the guide system 5 in a further perspective view. In Fig. 6, the guide system 5 is in a position in which the door leaf 3a is completely within the receiving compartment 8a (corresponds to the position shown in Fig. 2b). For reasons of clarity, the door leaf 3a is hidden.
[0062] The racks 19a, 19b each have a first end region and a second end region, wherein the first end region of the rack 19a, 19b is mounted on a first holding device 20a, 20b and the second end region of the rack 19a, 19b is mounted on a second holding device 20c, 20d, wherein the holding devices 20a, 20b, 20c, 20d are each to be fastened to the furniture wall 13a and the bearing device 18a, 18b is movable between the two holding devices 20a, 20b, 20c, 20d.
[0063] In other words, the end regions of the racks 19a, 10b are each mounted on a holding device 20a, 20b, 20c, 20d, wherein the holding devices 20a, 20b, 20c, 20d are each to be fastened to the furniture wall 13a.
[0064] The holding devices 20a, 20b, 20c, 20d are preferably designed to hold the at least one rack 19a, 19b at a distance from the furniture wall 13a in a fastened state of the holding device 20a, 20b, 20c, 20d.
[0065] The bearing device 18a, 18b can therefore be moved between the holding devices 20a, 20b, 20c, 20d, with the rack 19a, 19b spaced from the furniture wall 13a. In this way, the relative distance between the gear 24a, 24b and the rack 19a, 19b can be kept constant, so that the gear 24a, 24b can always be moved along the racks 19a, 19b with a constant engagement depth. Fig. 7a shows the guide system 5 in a perspective view from the front. The guides 15, 16 can be seen, preferably in the form of guide rails 15a, 16a, wherein the support 11 with the hinges 10 for the movable mounting of the door leaf 3a in an assembly position is movable along the guides 15, 16.
[0066] The rack 19a is to be fastened with one end region to the furniture wall 13a via the holding device 20a, while the other end of the rack 19a is also to be fastened to the furniture wall 13a via the holding device 20c (Fig. 6). The bearing device 18a of the carrier 11 is movable between the two holding devices 20a, 20c along the rack 19a.
[0067] To compensate for a misalignment between the (upper) first rack 19a and the (lower) second rack 19b, at least one adjusting device 29 is provided. The adjusting device 29 allows the position of the rack 19a relative to the at least one retaining device 20a, 20c to be adjusted.
[0068] The adjustment device 29 can, for example, have at least one rotatable adjustment wheel 29a, wherein a position of the rack 19a relative to the holding device 18a can be adjusted by rotating the at least one adjustment wheel 29a.
[0069] By means of the adjusting device 29, a misalignment, in particular a tilting, of at least one door leaf 3a can be corrected, wherein the misalignment is caused by a torsion of the support 11 and / or by a weight of the door leaf 3a.
[0070] In other words, the position of the support 11 relative to the rack 19a can be adjusted by the adjusting device 29, whereby mobility between the rack 19a and the holding devices 20a, 20c to be fastened to the furniture wall 13a is permitted.
[0071] According to one embodiment, it can be provided that the front end of the rack 19a is connected in a movement-coupled manner to the adjusting element 29a of the holding device 20c, while the rear end of the rack 19a is slidably guided in the guide 23a (Fig. 4) of the holding device 20a.
[0072] Fig. 7b shows the area "A" framed in Fig. 7a in an enlarged view. The adjusting wheel 29a is rotatably mounted 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. The
[0073] Linear guide 28 of the bearing device 18a for the movable mounting of the rack 19a.
[0074] At least one sliding device 30 can be provided, by which the frictional resistance between the at least one bearing device 18a, 18b and the at least one rack 19a, 19b can be reduced. The at least one sliding device 30 can, for example, have a rolling element 30a, which is rotatable about an axis, preferably extending vertically in the assembled position.
[0075] Due to a tilting of at least one door leaf 3a caused by the weight, it is possible that a side of the rack 19a opposite the provided teeth of the rack 19a is pressed against the bearing device 18a. For this reason, the sliding device 30 is provided to reduce the frictional resistance between the rack 19a and the bearing device 18a.
[0076] The at least one adjustment wheel 29a of the adjustment device 29 can be designed for manual operation and / or can be directly accessible to a person from the front in the assembled state of the guide system 5.
[0077] Fig. 8a shows a perspective view of the rack 19a with the two holding devices 20a, 20c for fastening to the furniture wall 13a as well as with the bearing device 18a for movable mounting along the rack 19a.
[0078] The holding devices 20a, 20c to be fastened to the furniture wall 13a each have a guide 23a for the movable mounting of the rack 19a. Fig. 8b shows the area framed in Fig. 8a in an enlarged view. At least one gear 24a is rotatably mounted on the mounting device 18a, the gear 24a being movable along the rack 19a.
[0079] The at least one rack 19a has a first longitudinal side 31a with teeth that engage or can be brought into engagement with the at least one gear 24a. The rack 19a further has a second longitudinal side 31b opposite the first longitudinal side 31a, wherein the at least one sliding device 30 can be placed against the second longitudinal side 31b of the rack 19a.
[0080] The sliding device 30 for reducing the frictional resistance between the rack 19a and the bearing device 18a can have at least one rolling body 30a which can be placed on the second longitudinal side 31b of the rack 19a.
[0081] In the embodiment shown, the sliding device 30 has a plurality of rolling elements 30a which are spaced apart from one another in a longitudinal direction of the rack 19a and / or are arranged in at least two running planes which lie one above the other in the assembly position.
[0082] Fig. 9 shows a side view of the furniture wall 13a with a fully extended door leaf 3a. The arrangement consisting of racks 19a, 19b, gears 24a, 24b, bearing devices 18a, 18b, and optionally the synchronization rod 25 together form a compensation device for compensating a tilting moment 32 of the support 11 or the door leaf 3a arranged thereon about a tilting axis 34 by means of a restoring moment 33.
[0083] When the support 11 or the door leaf 3a is oriented vertically, the tilt axis 34 is oriented horizontally. The compensation device with the aforementioned components therefore ensures that at least one door leaf 3a is stably guided in every position without excessive tilting of the door leaf 3a relative to the guides 14, 15, 16 occurring. Fig. 10a shows the (upper) first bearing device 18a in engagement with the (upper) first toothed rack 19a. The toothed wheel 24a is rotatably mounted on the bearing device 18a. The bearing device 18a is arranged on the support 11, the door leaf 3a being pivotally mounted on the support 11 via the hinges 10. This means that the toothed wheel 24a is pulled in the direction M1 by the weight of the door leaf 3a. The tooth flank 17 of the gear 24a thus presses against the teeth of the rack 19a in the direction Ml .The interaction of the oblique tooth flank 17 of the gear 24a with the oblique toothing of the rack 19a results in a force which presses the second longitudinal side 31b (see Fig. 8b) of the rack 19a, facing away from the first longitudinal side 31a, against the sliding device 30 with the rolling elements 30a. The sliding device 30 is thus provided to reduce the frictional resistance between the second longitudinal side 31b of the rack 19a and the upper bearing device 18.
[0084] Fig. 10b, on the other hand, shows the (lower) second bearing device 18b in engagement with the (lower) second rack 19b. The second gear 24b is rotatably mounted on the second bearing device 18b. The second bearing device 18b is arranged at a distance from the first bearing device 18a on the support 11, wherein the door leaf 3a is pivotally mounted on the support 11 via the hinges 10. This means that the second gear 24b of the (lower) second bearing device 18b is pressed in the direction M2 by the weight of the door leaf 3a. The tooth flank 17 of the second gear 24b therefore presses against the teeth of the second rack 19b in the direction M2. The interaction of the oblique tooth flank 17 of the second gear 24b with the oblique toothing of the second rack 19b results in a force which presses the longitudinal side 31b of the second rack 19b facing away from the first longitudinal side 31a against the second sliding device 30 with the rolling elements 30a.The second sliding device 30 is thus provided to reduce the frictional resistance between the longitudinal side 31b of the second rack 19b and the (lower) second bearing device 18b.
