Description

Field of the Invention

[0001] The present invention relates to a guiding system for guiding at least one movably supported door leaf, in particular a folding sliding door, along a furniture wall, the guiding system comprising:

[0002] - at least one carrier for pivotally supporting the at least one door leaf,

[0003] - at least one guide member, in particular a guide rail, to be fixed to the furniture wall for the movement of the at least one carrier along the furniture wall,

[0004] - at least one guiding device for slidably supporting the at least one carrier along the at least one guide member,

[0005] - at least one rack and at least one gear engageable or engagable into the rack, wherein the gear can move at least partially along the rack and can rotate by engaging into the rack when the carrier moves along the guide member.

[0006] Furthermore, the present invention relates to a piece of furniture having a furniture body, at least one door leaf movably supported relative to the furniture body, in particular a folding sliding door, and having at least one guiding system of the type to be described, the guiding system being for the movement of the at least one door leaf relative to the furniture body. Background Art

[0007] A guiding system for a door leaf is shown in US2004 / 0046488 A1, by means of which the door leaf can move along the side wall of a piece of furniture. The door leaf can thus be pushed into the furniture in the depth direction, wherein the door leaf releases an entrance inside the furniture body in the pushed-in position. The door leaf is pivotally supported on the carrier by hinges, wherein the carrier can move along the side wall of the furniture body by means of a plurality of racks spaced apart from each other in the height direction and a plurality of gears engaged into the racks. By means of a synchronizing shaft, the rotational movements of the gears can be synchronized with each other. The disadvantage of this structure is that the guiding system is only suitable for door leaves with a relatively small weight. The challenge in guiding the door leaf along the furniture wall is that the door leaf tends to tilt due to its weight. This further leads to an undesired torsion of the carrier and wedging of the door leaf relative to the guide member. In addition, due to the weight of the door leaf, the upper gears may no longer engage in the upper racks provided for them as set, while the lower gears may jam with the lower racks due to the acting weight of the door leaf. This condition results in the movement of the door leaf being impossible or at least significantly difficult. In addition, undesired running noise occurs, mainly because all the racks are fixedly mounted on the side wall flatly. In this way, the furniture body may become a resonator due to the vibrations occurring and thus additionally enhance the noise. Summary of the Invention

[0008] The object of the present invention is to provide a guidance system of the type described at the beginning while avoiding the disadvantages discussed above.

[0009] According to the invention, this is solved by the features of claim 1. Other advantageous embodiments of the invention are given in the dependent claims.

[0010] According to the invention, it is proposed that the at least one carrier has at least one supporting device for supporting the at least one rack.

[0011] In other words, the at least one rack is supported on the carrier, the at least one door leaf can be pivotably arranged on the carrier, and the carrier can move along at least one guide arranged on the furniture wall in the assembled position. In this way, it is ensured that the at least one gear has a defined spacing relative to the at least one rack, wherein the gear always moves relative to the rack with a preset engagement depth. In addition, in this way, disturbing running noises can be reduced.

[0012] According to one embodiment, it can be provided that the at least one supporting device and the at least one rack can move relative to each other, preferably can slide relative to each other.

[0013] According to a preferred embodiment, it can be provided that the at least one supporting device has at least one linear guide, preferably a U-shaped profile, for movably, preferably slidably, supporting the at least one rack.

[0014] By means of the at least one linear guide, the engagement depth of the at least one gear can be limited such that the teeth of the at least one gear only partially engage into the tooth spaces 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.

[0026] Figure 1a A perspective view of a piece of furniture 1 is shown, which has a furniture body 2 and door leaves 3a, 3b; 4a, 4b that are movable relative to the furniture body. The door leaves 3a, 3b and the door leaves 4a, 4b can be moved between a first position and a second position by means of a guiding system 5. In the first position, the door leaves 3a, 3b; 4a, 4b are oriented substantially coplanarly with each other, and in the second position, the door leaves 3a, 3b; 4a, 4b are oriented substantially parallel to each other.

[0027] The door leaves 3a, 3b can be pushed into a receiving compartment 8a on the side of the furniture body 2 in the (parallel) second position, while the door leaves 4a, 4b can be pushed into another receiving compartment 8b in their parallel positions with respect to each other.

[0028] The mode of operation will be explained below with the aid of the door leaves 3a and 3b, where the same embodiment applies to the door leaves 4a, 4b.

[0029] The guiding system 5 includes a guide rail 7 having a longitudinal direction (L), wherein a guide slider 6 that can be connected to the second door leaf 3b is movably supported along the guide rail 7. The guide rail 7 extends substantially parallel to the end side of the furniture body 2 in the assembled state.

[0030] Figure 1b shows a piece of furniture 1, in which the door leaves 3a, 3b move from Figure 1a the coplanar position shown to an angular position relative to each other. The first door leaf 3a is pivotally supported on a carrier 11 by two or more hinges 10, wherein the carrier 11 (together with the door leaves 3a, 3b) can be pushed into a lateral receiving compartment 8a in the depth direction Z.

[0031] The carrier 11 is in Figure 1b a conveying position, in which the carrier 11 is connected to a guide rail 7 in the longitudinal direction L, so that a guide slider 6 can be conveyed back and forth between the guide rail 7 and the carrier 11. In the shown conveying position, the carrier 11 and the guide rail 7 are releasably locked, wherein the locking between the guide rail 7 and the carrier 11 can be released by guiding the slider 6 into the carrier 11 or guiding the slider 6 onto the carrier 11.

[0032] The carrier 11 is formed in the shape of an elongated column, and its length is at least equivalent to half of the height of the door leaves 3a, 3b. The two door leaves 3a, 3b are hingedly connected to each other via at least one hinge fitting 9 about a vertically extending axis. The second door leaf 3b is movably supported along the guide rail 7 by a guide slider 6.

[0033] Figure 2a shows a piece of furniture 1 having door leaves 3a and 3b, which are now oriented parallel to each other. Due to the entry of the guide slider 6, the carrier 11 has been unlocked from the guide rail 7, wherein the carrier 11 (together with the guide slider 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 extends transversely to, preferably substantially perpendicular to, the longitudinal direction L of the guide rail 7.

[0034] Figure 2b shows a piece of furniture 1 having door leaves 3a, 3b, which are now located in the receiving compartment 8a in a fully pushed-in state. The door leaves 3a, 3b can thus be moved from a first position according to Figure 1a and a second position according to Figure 2b , in the first position, the door leaves 3a, 3b are oriented substantially coplanarly with each other, and in the second position, the door leaves 3a, 3b are oriented substantially parallel to each other and are received within the receiving compartment 8a.

[0035] In this way, for example, a kitchen 12 as shown in Figure 2a , 2b can be completely covered, so that the kitchen 12 can be separated from the rest of the living space.

[0036] In the illustrated embodiment, the receiving compartment 8a is formed by a first furniture wall 13a and a second furniture wall 13b that is spaced substantially parallel to the first furniture wall 13a, wherein the door leaves 3a, 3b can be pushed between the two furniture walls 13a, 13b in parallel positions relative to each other. The two furniture walls 13a, 13b are each formed as side walls of the furniture body 2 in the illustrated embodiment.

[0037] Figure 3 A perspective view of the furniture wall 13a is shown, which has a guiding system 5 for guiding at least one door leaf 3a. For reasons of overview, the second door leaf 3b hingedly connected to the first door leaf 3a is not shown.

[0038] The guiding system 5 includes at least one longitudinally extending carrier 11, and at least one door leaf 3a is swingably supported on the carrier 11, for example, by two or more hinges 10. The length of the carrier 11 can be substantially equivalent to the height of the door leaf 3a.

[0039] The guiding system 5 includes at least one guide member 14, preferably a guide rail 14a, to be fixed to the furniture wall 13a, for the movement of at least one carrier 11 along the furniture wall 13a.

[0040] In the illustrated embodiment, additional guide members 15, 16, preferably additional guide rails 15a, 16a, are provided, and the at least one carrier 11 can be moved along the furniture wall 13a by the additional guide members. The guide members 14, 15, 16 are fixed to the furniture wall 13a at a vertical spacing from each other.

[0041] The carrier 11 can be moved along at least one guide member 14 by at least one guiding device 21. The guiding device 21 can have at least one pulley 21a ( Figure 4 ), preferably a plurality of pulleys 21a, which are capable of rolling along at least one guide member 14.

[0042] The guiding device 21 can have a plurality of pulleys 21a, which are rotatably supported about a rotation axis oriented in a first direction. In addition, additional pulleys can be provided, which are rotatably supported about a rotation axis oriented in a second direction.

[0043] The guiding system 5 has at least one rack 19a, wherein, when the carrier 11 moves along at least one guide member 14, at least one gear 24a ( Figure 4 ) can move on at least one rack 19a.

[0044] In the illustrated embodiment, at least one second rack 19b is provided, wherein, when the carrier 11 moves along the guide members 14, 15, 16, at least one second gear 24b ( Figure 4 ) can move on the second rack 19b.

[0045] According to the setting of the present invention, the carrier 11 has at least one supporting device 18a, 18b, and the supporting device is used for supporting at least one rack 19a, 19b.

[0046] The racks 19a, 19b have end regions, and at least one holding device 20a, 20b to be fixed on the furniture wall 13a is arranged therein. The end regions of the racks 19a, 19b are supported on the holding device.

[0047] The holding devices 20a, 20b have at least one fixing part 22a, 22b, and the end regions of the racks 19a, 19b can be fixed on the furniture wall 13a through the fixing part. The fixing parts 22a, 22b of the holding devices 20a, 20b can include, for example, holes for screws to pass through and / or at least one pin for fixing on the furniture wall 13a.

[0048] The holding devices 20a, 20b respectively have guides 23a, 23b for movably supporting the racks 19a, 19b. In other words, the racks 19a, 19b are movably supported relative to the holding devices 20a, 20b.

[0049] The at least one gear 24a, 24b for running on the racks 19a, 19b ( Figure 4 ) can be rotatably arranged on the carrier 11 or rotatably arranged on at least one supporting device 18a, 18b of the carrier 11, for example.

[0050] Figure 4 Another perspective view of the furniture wall 13a is shown, and the furniture wall has a guiding system 5 according to Figure 3 . Two supporting devices 18a, 18b of the carrier 11 can be seen, and at least one gear 24a, 24b is rotatably supported above or in the supporting devices 18a, 18b or on the carrier 11 respectively. The at least one gear 24a, 24b can be rotatably supported around an axis extending parallel to the longitudinal direction E of the carrier 11 and is used for meshing with the at least one rack 19a, 19b.

[0051] In order to synchronize the rotational movements of the gears 24a, 24b, at least one synchronizing rod 25 is provided, and the synchronizing rod extends substantially parallel to the longitudinal direction E of the carrier 11. Therefore, the rotational movements of the gears 24a, 24b can be synchronized with each other through the rotational movement of the synchronizing rod 25 around its own axis.

[0052] In the shown embodiment, at least one stabilizing device 26 is provided, and through this stabilizing device, the synchronizing rod 25 can be prevented from bending or at least restricted from bending in a direction extending transversely to the longitudinal direction E of the synchronizing rod 25.

[0053] At least one stabilizing device 26 can be arranged in the central region of the synchronizing rod 25 and / or can have at least one opening 27 for the synchronizing rod 25 to pass through.

[0054] Figures 5a to 5c Respectively shown Figure 4 of the enlarged detail view.

[0055] Figure 5a Shown in an enlarged view is Figure 4 the region "A" framed in. The supporting device 18a for movably supporting the rack 19a and fixed to the carrier 11 can be seen. The supporting device 18a has at least one rotatable gear 24a which meshes with the rack 19a.

[0056] The supporting device 18a can have at least one linear guide 28 for movably supporting the rack 19a. When the carrier 11 moves along the guide 14, the supporting device 18a is movably supported relative to the rack 19a. In the illustrated embodiment, at least one linear guide 28 has a U-shaped profile in which the rack 19a can be guided.

[0057] Figure 5b Shown in an enlarged view is Figure 4 the region "B" framed in. The stabilizing device 26 can be seen, by which the synchronizing rod 25 can be prevented or at least restricted from bending in a direction extending transversely to the longitudinal direction E of the synchronizing rod 25.

[0058] In the illustrated embodiment, the stabilizing device 26 has a fixing section 26a for abutting against the carrier 11 and a holding tab 26b for holding the synchronizing rod 25, which projects laterally, preferably at a right angle, from the fixing section 26a. The fixing section 26a has at least one fixing part 26c through which the stabilizing device 26 can be fixed to the carrier 11. The holding tab 26b has at least one opening 27, such as a cylindrical one, for the synchronizing rod 25 to pass through.

[0059] Figure 5c Shown in an enlarged view is Figure 4 the region "C" framed in. The lower second supporting 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 each other by means of the at least one synchronizing rod 25. The second supporting device 18b also has a linear guide 28, preferably a U-shaped profile, for receiving and guiding the second rack 19b.

[0060] Figure 6 The guiding system 5 is shown in another perspective view. The guiding system 5 is in Figure 6in a position where the door leaf 3a is completely located within the receiving cell 8a (corresponding to the position according to Figure 2b ). For reasons of clarity, the door leaf 3a is hidden.

[0061] The racks 19a, 19b each have a first end region and a second end region, wherein the first end regions of the racks 19a, 19b are supported on the first holding devices 20a, 20b, and the second end regions of the racks 19a, 19b are supported on the second holding devices 20c, 20d, wherein the holding devices 20a, 20b, 20c, 20d should be fixed to the furniture wall 13a respectively, and the supporting devices 18a, 18b can move between the two holding devices 20a, 20b, 20c, 20d.

[0062] In other words, the end regions of the racks 19a, 10b are supported on the holding devices 20a, 20b, 20c, 20d respectively, wherein the holding devices 20a, 20b, 20c, 20d should be fixed to the furniture wall 13a respectively.

[0063] The holding devices 20a, 20b, 20c, 20d are preferably configured such that at least one of the racks 19a, 19b is spaced apart from the furniture wall 13a in the fixed state of the holding devices 20a, 20b, 20c, 20d.

[0064] Therefore, the supporting devices 18a, 18b can move between the holding devices 20a, 20b, 20c, 20d, wherein the racks 19a, 19b are spaced apart from the furniture wall 13a. In this way, the relative spacing between the gears 24a, 24b and the racks 19a, 19b can be kept constant, so that the gears 24a, 24b can always move along the racks 19a, 19b with a constant meshing depth.

[0065] Figure 7a The guiding system 5 is shown in a perspective view as seen from the front. The guides 15, 16, preferably in the form of guide rails 15a, 16a, can be seen, wherein the carrier 11 can move along the guides 15, 16 in the assembly position together with the hinge 10 for movably supporting the door leaf 3a.

[0066] One end region of the rack 19a is fixed to the furniture wall 13a by the holding device 20a, wherein the other end of the rack 19a is also fixed to the furniture wall 13a by the holding device 20c ( Figure 6 ). The supporting device 18a of the carrier 11 can move along the rack 19a between the two holding devices 20a, 20c.

[0067] To compensate for the misalignment between the first rack 19a (upper) and the second rack 19b (lower), at least one adjusting device 29 is provided. The position of the rack 19a relative to at least one holding device 20a, 20c can be adjusted by means of the adjusting device 29.

[0068] The adjusting device 29 can for example have at least one rotatable adjusting wheel 29a, wherein the position of the rack 19a relative to the holding device 18a can be adjusted by rotating the at least one adjusting wheel 29a.

[0069] By means of the adjusting device 29, the misalignment, in particular the inclination, of at least one door leaf 3a can be corrected, wherein the misalignment is caused by the torsion of the carrier 11 and / or by the weight of the door leaf 3a.

[0070] In other words, by means of the adjusting device 29, the position of the carrier 11 relative to the rack 19a can be adjusted, wherein play between the rack 19a and the holding devices 20a, 20c to be fixed to the furniture wall 13a is permitted.

[0071] According to one embodiment, it can be provided that the front end portion of the rack 19a is connected in a kinematic coupling to the adjusting element 29a of the holding device 20c, while the rear end portion of the rack 19a is slidably guided in the guide 23a of the holding device 20a ( Figure 4 ).

[0072] Figure 7b The area "A" framed in FIG. 7A is shown in an enlarged view. The 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. The linear guide 28 of the support device 18a for movably supporting the rack 19a can be seen.

[0073] At least one sliding device 30 can be provided, by means of which the frictional resistance between at least one support device 18a, 18b and at least one rack 19a, 19b can be reduced. The at least one sliding device 30 can for example have rolling elements 30a, which can rotate about an axis which preferably extends vertically in the installed position.

[0074] Due to the inclination of at least the door leaf 3a caused by its weight, it is possible that the side of the rack 19a opposite the teeth provided on the rack 19a is pressed against the support device 18a. Therefore, a sliding device 30 for reducing the frictional resistance is provided between the rack 19a and the support device 18a.

[0075] At least one adjusting wheel 29a of the adjusting device 29 can be configured for manual operation and / or can be directly accessible from the front for a person in the assembled state of the guide system 5.

[0076] Figure 8a Shows a perspective view of a rack 19a having two holding devices 20a, 20c for fixing to a furniture wall 13a and having a supporting device 18a for a movable support along the rack 19a.

[0077] The holding devices 20a, 20c to be fixed to the furniture wall 13a each have a guide 23a for movably supporting the rack 19a.

[0078] Figure 8b Shows in an enlarged view the area framed in Figure 8a At least one gear 24a is rotatably supported on the supporting device 18a, wherein the gear 24a can move along the rack 19a.

[0079] At least one rack 19a has a first longitudinal side 31a with teeth that engage or can engage with at least one gear 24a. The rack 19a also has a second longitudinal side 31b opposite the first longitudinal side 31a, wherein the at least one sliding device 30 can abut 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 supporting device 18a can have at least one rolling element 30a that can abut against the second longitudinal side 31b of the rack 19a.

[0081] In the illustrated embodiment, the sliding device 30 has a plurality of rolling elements 30a that are arranged spaced apart from each other in the longitudinal direction of the rack 19a and / or are arranged in at least two operating planes that are stacked one above the other in the assembled position.

[0082] Figure 9 Shows the furniture wall 13a together with the fully pulled-out door leaf 3a in a side view. The arrangement consisting of the racks 19a, 19b, gears 24a, 24b, supporting devices 18a, 18b and, if necessary, the synchronizing rod 25 together constitutes a compensation device for compensating for the tilting moment 32 of the carrier 11 or the door leaf 3a arranged on the carrier about the tilting axis 34 by means of a restoring moment 33.

[0083] When the carrier 11 or the door leaf 3a is vertically oriented, the tilting axis 34 is horizontally oriented. The compensation device having the above-mentioned components thus ensures that the at least one door leaf 3a is stably guided in each position without excessive tilting of the door leaf 3a relative to the guides 14, 15, 16 occurring here.

[0084] Figure 10aIt shows that the first support device 18a (above) engages with the first rack 19a (above). The gear 24a is rotatably supported on the support device 18a. The support device 18a is arranged on the carrier 11, wherein the door leaf 3a is swingably supported on the carrier 11 by means of a hinge 10. This means that the gear 24a is pulled in the direction M1 by the weight of the door leaf 3a. The tooth surface 17 of the gear 24a thus presses against the teeth of the rack 19a in the direction M1. The interaction between the inclined tooth surface 17 of the gear 24a and the inclined teeth of the rack 19a generates a force that presses the second longitudinal side 31b of the rack 19a, which faces away from the first longitudinal side 31a (see Figure 8b ) against the sliding device 30 with rolling elements 30a. Thus, the sliding device 30 is provided to reduce the frictional resistance between the second longitudinal side 31b of the rack 19a and the upper support device 18.

[0085] Conversely, Figure 10b It shows that the second support device 18b (below) engages with the second rack 19b (below). The second gear 24b is rotatably supported on the second support device 18b. The second support device 18b is arranged on the carrier 11 at a distance from the first support device 18a, wherein the door leaf 3a is swingably supported on the carrier 11 by means of a hinge 10. This means that the second gear 24b of the second support device 18b (below) is pushed in the direction M2 by the weight of the door leaf 3a. The tooth surface 17 of the second gear 24b thus presses against the teeth of the second rack 19b in the direction M2. The interaction between the inclined tooth surface 17 of the second gear 24b and the inclined teeth of the second rack 19b generates a force that presses the longitudinal side 31b of the second rack 19b, which faces away from the first longitudinal side 31a, against the second sliding device 30 with 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 second support device 18b (below).
