Description

[0001] The present invention relates to a guide fitting for guiding a body part mounted so as to be movable both translationally and rotationally, according to the preamble of claim 1.

[0002] The invention further relates to a furniture or household appliance element according to the preamble of claim 10.

[0003] Such furniture or household appliance elements such as shelves or racks, in which a body part is mounted in a support body so that it can move both rotationally and translationally, are known, for example, from DE 10 2019 109 866 A1.

[0004] A translational-rotational bearing is used to carry out the translational-rotational movement of the body part.

[0005] Particularly in the case of larger and / or higher furniture or household appliance elements, such as refrigerators and freezers or wine coolers, it is necessary for stability reasons to additionally support the movement of the translationally and rotationally movable body part.

[0006] For this purpose, it is known, for example, from DE 10 2019 132 207 A1 to arrange a guide bearing between the cover plates of the support body and the body part, with which the translational-rotational movement is additionally guided.

[0007] Such a furniture or household appliance element has proven itself in practice.

[0008] To activate such a translational-rotational movement, it may be necessary in some situations to pull the body part to be moved forward from a first end position.

[0009] Attaching a handle is a suitable solution for this. However, such a handle may potentially limit the movement of the body part relative to the support body, as such a handle would prevent, for example, a 180° rotation of the body part relative to the support body to reach a desired position with the same surface area as the starting position, by bumping into the support body before reaching the 180° rotated position.

[0010] The object of the present invention is to provide a guide fitting and a furniture or household appliance element with which the triggering of a combined translational-rotational movement is facilitated.

[0011] This object is achieved by a guide fitting having the features of claim 1.

[0012] The problem is further solved by a furniture or household appliance element having the features of claim 10.

[0013] The guide fitting according to the invention has a guide cam track, a guide element guided in the at least one guide cam track and a linear guide with at least one first connecting part and a second connecting part movable relative to the first connecting part, one of which is fixedly coupled to the guide element and the other is coupled to the guide cam track by means of a pivot bearing.

[0014] The guide cam track or the guide element can be fixed to the body part.

[0015] The guide fitting is characterized by at least one ejection device with a releasable force accumulator, with which the body part can be driven from at least one end position by exerting force against an ejection direction along a limited path.

[0016] The guide fitting further comprises at least one activator for unlocking the energy storage device of the ejection device.

[0017] With a guide fitting designed in this way, it is easy to trigger a combined translational-rotational movement of the body part relative to a stationary base.

[0018] Advantageous embodiments of the invention are the subject of the subclaims.

[0019] According to an advantageous embodiment, the at least one ejection device is arranged stationary relative to the guide element.

[0020] In a preferred embodiment, two activators are arranged on or at a fixed distance from the guide cam track.

[0021] By arranging such activators on the guide cam track, it is possible to easily trigger the translational-rotational movement via the rotational movement of the body part by pressing the body part against the desired rotational movement.

[0022] According to a preferred development, the guide cam track has a guide groove receiving the guide element and an arm extending outside the guide groove, on which the two activators are arranged, in particular formed.

[0023] By molding the activators onto the guide cam track, the assembly effort of such a guide fitting is further reduced.

[0024] According to a further advantageous embodiment, the guide fitting further comprises a carrier plate to which the at least one first connecting part of the linear guide, the guide element and the at least one ejection device are fixed.

[0025] The design of the guide fitting with such a carrier plate also simplifies the construction and assembly of the guide fitting.

[0026] In an advantageous further development, the carrier plate has a central region on which two first connecting parts of the linear guides aligned parallel to one another are fastened, and two mirror-symmetrically shaped edge regions, to each of which an ejection device is fixed.

[0027] This allows the translational-rotational movement to be triggered from two different end positions.

[0028] According to a further alternative embodiment, the at least one activator is arranged in a stationary manner on the second connecting part of the linear guide and the ejection device is arranged in a stationary manner on or near the first connecting part of the linear guide.

[0029] The arrangement of the activator on the linear guide also makes it possible to trigger the translational-rotational movement in a simple manner by activating the ejection device via the translational movement of the body part.

[0030] In all versions, the ejection device utilizes the relative movement between the stationary and initially almost translationally moving furniture.

[0031] The furniture or household appliance element according to the invention comprises a support body with a base support plate, a cover support plate and at least one side wall, a body part mounted so as to be movable both translationally and rotationally relative to the support body and comprising a base plate, a cover plate and at least one side wall.

[0032] A guide fitting is arranged between the cover support plate and the cover plate and / or between the base support plate and the base plate.

[0033] The guide fitting has at least one guide cam track and a guide element guided in or on the guide cam track, which are arranged on respective mutually facing surfaces of the cover support plate and the cover plate or the base support plate and the base plate.

[0034] The guide fitting further comprises a linear guide with connecting parts that can be displaced relative to one another in a translation direction, one of which is arranged on the cover support plate or the cover plate and the other is mounted on the other of the cover support plate or the cover plate by means of a pivot bearing.

[0035] The linear guide preferably consists of two guide rails aligned parallel to each other and guide rails that can be moved relative to these.

[0036] The guide fitting has at least one ejection device with a releasable force accumulator and at least one activator for unlocking the force accumulator of the ejection device, with which the body part can be driven from at least one end position by exerting force against an ejection direction along a limited path.

[0037] In an advantageous embodiment, the guide cam track is attached to the base plate or the cover plate of the body part and the guide element is fixedly attached to the base support plate or the cover support plate of the support body.

[0038] In a further advantageous embodiment, a first guide fitting is arranged between the base support plate and the base plate and a second guide fitting is arranged between the cover support plate and the cover plate.

[0039] An arrangement of two guide fittings is particularly suitable for furniture or household appliance elements with a larger height.

[0040] In a further advantageous embodiment, the body part is movable relative to the support body from a first functional position into a second functional position rotated by a predetermined angle to the starting position, wherein in both functional positions the base plates and the cover plates of the body part and the support body are aligned with each other in matching geometries.

[0041] Preferred embodiments of the invention are explained in more detail below with reference to the accompanying drawings.

[0042] In the following description of the figures, terms such as top, bottom, left, right, front, rear, etc., refer exclusively to the exemplary representation and position of the guide fitting, furniture or household appliance element, ejector, activator, guide fitting, guide cam track, linear guide, and the like chosen in the respective figures. These terms are not to be understood as limiting; i.e., these references may change due to different operating positions or the mirror-symmetrical design, etc.

[0043] In the Fig. 1 - 5, the reference numeral 1 denotes an embodiment variant of a furniture element according to the invention.

[0044] The furniture element 1 shown here essentially consists of a support element 2 with a base support plate 21 and a cover support plate 22 and side walls 23 connecting the base support plate 22 to the cover support plate 21 as well as a body part 3 which can be moved simultaneously in translation and rotation relative to the support element 2.

[0045] Instead of the side wall 23 connecting the floor support plate 21 to the cover support plate 22, a design variant of the support element 2 without a side wall 23 is also conceivable, for example when fastening the floor support plate 21 and the cover support plate 22 to a building wall.

[0046] The body part 3 also has a base plate 31, a cover plate 32 and a connecting element connecting the base plate 31 to the cover plate 32, in the embodiment shown in the form of at least one side wall 33.

[0047] In the embodiment shown in these figures, the shelf-like body part 3 has a square base, with two side walls 33, which form an interior in a Fig. 1 shown closed position and two open vertical sides, shown in the Fig. 2 and Fig. 3, which allow access to the interior.

[0048] Instead of the side walls, it is also conceivable to connect the base plate 31 with the cover plate 32 via corner posts 36, shown as an example in Fig. 3, or a central post in the center of the base plate 31 or cover plate 32.

[0049] In the embodiment shown here, the interior of the body part 3 has several shelves 35. However, other configurations or subdivisions of the interior of the body part 3 are also conceivable.

[0050] How to continue in the Fig. 2, Fig. 4 and Fig. 5 is shown, is between the cover support plate 22 and the cover plate 32, shown in the Fig. 2 and Fig. 4, and / or between the floor support plate 21 and the floor plate 31, shown in Fig. 5, a guide fitting 4 is arranged, with which the simultaneous translational and rotational movement of the body part 3 relative to the support element 2 is enabled.

[0051] Preferably, the body part 3, which here has a square base, is movable relative to the support element 2 from a first functional position into a second functional position rotated by a predetermined angle relative to the starting position, wherein in both functional positions the base (support) plates 21, 31 and the cover (support) plates 22, 32 of the body part 3 and the support element 2 are aligned with one another in matching geometries.

[0052] It is also conceivable, for example, in the case of a body part 3 with a rectangular base and unequal side lengths, that the second rotated functional position is not congruent with the first functional position. For example, after rotating such a body part, a different depth must be reached in order to also engage a building wall or a wall of the support element 2.

[0053] Preferred design variants of such a guide fitting 4 are shown in the Fig. 6-16 are shown in more detail.

[0054] A first embodiment of such a guide fitting 4 is shown in the Fig. 6 - 10 shown.

[0055] As in Fig. 6 and Fig. 7, the guide fitting 4 has a guide cam track 5 and a guide element 11 guided in the guide cam track 5.

[0056] The guide fitting 4 further comprises a linear guide 6 with at least two connecting parts which are movable relative to one another, one of which is fixedly coupled to the guide element 11 and the other of which is coupled to the guide cam track 5 by means of a pivot bearing 9.

[0057] In the embodiment shown in the figures, the linear guide consists of two guide rails 61 aligned parallel to one another and guide rails 62 that can be moved relative to these.

[0058] Other designs of linear guides are also conceivable, for example in the form of a guide rail and a roller carriage, rack or the like guided on or along this.

[0059] The guide cam track 5 or the guide element 11 can be fixedly fastened to the body part 3.

[0060] How to continue in the Fig. 6 and Fig. 7, the guide fitting 4 has at least one, in this embodiment two ejection devices 8, with a releasable force accumulator, with which the body part 3 can be driven from at least one end position by exerting force against an ejection direction B along a limited path.

[0061] The drive is effected by transmitting force to at least one activator 10, via which the energy storage device of the ejection device 8 is unlocked.

[0062] In the Fig. 6-10 is the guide cam track 5, as also shown as an example in the Fig. 4 and Fig. 5 can be seen, fixed to the cover plate 32 of the body part 3 or the base plate 31 of the body part 3.

[0063] The guide cam track 5 has a guide groove 51 in which the guide element 11, designed here as a wheel, can be guided.

[0064] The guide element 11, like the first two connecting parts—here the guide rails 61 of the linear guides 6 and the ejection devices 8—is fixed to a support plate 7. Alternatively, the guide rails 61, the guide element 11, and / or the ejection devices can be arranged directly on the top support plate 22 and / or the bottom support plate 21.

[0065] The support plate 7, in turn, is fixed in a fixed position to the top support plate 22 or the bottom support plate 21 of the base, or in the case of a furniture element 1, to the support body 2.

[0066] To fix the guide rails 61 of the linear guides 6 to the support plate 7, different fixing elements 73, 74, 75 are provided in a central area 71 of the support plate 7.

[0067] Thus, the fixing elements 75 are designed as pins protruding from the central region 71 of the support plate 7, which are received in bores provided for this purpose in a fastening section of the respective guide rail 61 and thus enable a positive fixing of the guide rails 61 in the plane of the support plate 7.

[0068] To prevent lifting, the additional fixing elements 73 and 74 are provided, which are plate-like and overlap the fastening area of ​​the guide rails 61.

[0069] An ejection device 8 is attached to each edge region 72 of the carrier plate 7.

[0070] The ejection devices 8 are known per se from the prior art and comprise a housing 81, an ejector 82 coupled in the housing 81 along a track 83 with the energy accumulator (not shown), which ejector 82 is actuated by means of an activator 10 from a force which is arranged, for example, in Fig. 8 shown relaxed extended position into a Fig. 10 shown tensioned function can be moved by pressing the ejector 82 against the ejection direction B.

[0071] This tensioning of the energy storage device takes place in the movement sequence of the body part 3 relative to the support body 2 when moving into an end position of the body part 3, as shown in the Fig. 1 and Fig. 3, in which the body part 3, viewed in a horizontal plane relative to the support body 2, occupies the same space in both different end positions. Other ejection devices can also be used, in which the tensioning of the energy accumulator can occur additionally or alternatively upon further extension of the body part 3.

[0072] If the body part 3 is to be moved out of this position, the body part 3 can be slightly pressed in against the direction of rotation R1, R2 controlled by the guide cam track 5, using the example of Fig. 2 by pressing towards R2, using the activator 10, as shown for example in Fig. 10 shown, can be unlocked.

[0073] After unlocking the energy storage device, it drives the ejector 82 in the ejection direction B. The ejector 82 presses against the activator 10 and thereby pushes the guide cam track 5 and with it the body part 3 in the ejection direction B from the end position into the Fig. Position shown in 2.

[0074] After this ejection process, the user can easily move the body part 3 further into the desired position.

[0075] Furthermore, the Fig. In the embodiment shown in Figures 6 - 10, two activators 10 are arranged on an arm 52 branching off from a central region of the guide cam track 5.

[0076] The geometry of the arm 52 is designed such that the activators 10 slide along the respective outer sides of the ejection devices 8 and accordingly come into contact with a respective ejector 82 at a predetermined position before reaching the end position of the body part 3.

[0077] The alignment of the two linear guides 6 fastened here to the support plate 7, i.e. the guide rails 61 and the linearly displaceable guide rails 62 on these, determine the translation direction A of the combined translation-rotation movement of the body part 3 relative to the support element.

[0078] The pivot bearing 9, which is mounted on the two guide rails 62, consists of a first and a second mounting plate 91, 93, wherein the second mounting plate 93 is mounted on the guide rails 62 and the first mounting plate 91 is mountable on the cover plate 32 or the base plate 31 of the body part 3. Fig. In the exemplary embodiment shown in Figure 9, a rotary plate 92 is additionally attached to the first mounting plate 91. The mounting plates 91, 93 are mounted so they can rotate relative to one another.

[0079] In the Fig. 11 and Fig. In the alternative embodiment shown in Figure 12, ejection devices 8 are fixed directly to the guide rails 62 of the linear guide 6.

[0080] The activators 10 are fixed here at a suitable location on the guide rail 61.

[0081] In this embodiment, the force transmission from the energy storage device of the ejection devices 8 is not carried out via the guide cam track 5, but via the linear guides 6.

[0082] A third variant of such a guide fitting 4 is shown in the Fig. 13 to 16.

[0083] In this embodiment, only one ejection device 8 is provided, the housing of which, like the guide rails 61, is fixed on the support plate 7 or alternatively on the base plate 31 or the cover plate 32 of the body part 3.

[0084] In this case, the activator 10 is arranged on the guide rail 62. This design variant thus represents a kinematic reversal of the design variant according to Fig. 11 and Fig. 12.

[0085] In Fig. 15, the ejector 82 of the ejection device 8 is shown in the position in which the body part 3 is in an end position.

[0086] Fig. 16 shows the ejector 82 of the ejection device 8 with the energy storage device relaxed, in which the guide rail 62 has been moved accordingly over the activator 10, which is accompanied by a movement of the body part 3 in the position shown here as an example in Fig. 2 shown position.
