Furthermore, a furniture or household appliance element (1) is described.

Description

[0001] The present invention relates to a translational-rotational fitting according to the preamble of claim 1 and to a furniture or household appliance element according to the preamble of claim 14.

[0002] Translational-rotation fittings of this type are known, for example, from WO 2022 / 157295 A1 or DE 10 2019 109 866 A1. They serve to move a first body relative to an interface, for example a second body, in one of two opposite directions of rotation and simultaneously in a predetermined translational direction, in order to move the first body, for example from a corner area, from a starting position to a position rotated by 90° or a multiple of 90°, without colliding with the walls defining the corner area.

[0003] When transporting furniture equipped with such translational-rotation fittings, it is necessary to secure the furniture component movable via the respective translational-rotation fitting, for example, the first cabinet, to prevent unintentional movement of this component during transport. Even if the translational-rotation fitting is transported separately, it is advantageous to prevent movement of the two fitting plates to avoid damage. Furthermore, it is beneficial to secure the translational-rotation fitting against unintentional movement of the fitting components relative to each other before installation.

[0004] The object of the present invention is therefore to further develop a translational-rotational fitting in such a way that unintentional movement of the furniture component or of a fitting plate during transport or assembly is effectively prevented. A further object of the invention is to secure the translational-rotational fitting against unintentional movement of the fitting components relative to each other before assembly.

[0005] This problem is solved by a translational-rotation fitting with the features of claim 1.

[0006] The translational-rotational fitting according to the invention, for the at least partially forced simultaneous translational-rotational movement of a furniture component, for example a first body, relative to an interface, for example a second body, in one of two opposite directions of rotation and in a predetermined translational direction, comprises a first fitting plate attachable to the furniture component and a second fitting plate attachable to the interface or the second body, which is simultaneously movable translationally and rotationally relative to the first fitting plate. The furniture component can, for example, also be designed as a table, a platform for arranging several furniture components, or other furniture element. The interface can, for example, also be a wall surface of a building.

[0007] The translational-rotation fitting further comprises a locking element that can be detachably attached to the first fitting plate and / or the second fitting plate, wherein, in the mounted state of the locking element, the fitting plates are fixed relative to each other by blocking the translational movement.

[0008] With such a translational-rotation fitting, safe assembly and safe transport of a piece of furniture equipped with such a translational-rotation fitting are easily made possible.

[0009] Advantageous embodiments of the invention are the subject of the dependent claims.

[0010] According to an advantageous embodiment of the invention, the translational-rotational fitting comprises at least one carriage guided along at least one carriage track extending in the translational direction on the second fitting plate, which is rotationally coupled to the first fitting plate. The locking element is designed as a blocking element that fixes the carriage in a starting position of the carriage track.

[0011] By blocking the slide with the locking element, the entire translational-rotational movement is prevented, since the translational movement of the translational-rotational fitting is accompanied by the rotational movement, and therefore blocking the translational movement provides sufficient security. Alternatively or additionally, the locking element can also block the rotational movement.

[0012] According to a further development of the translational-rotational fitting according to the invention, the locking element has a grip area and a blocking area that fixes the carriage in the starting position of the carriage track.

[0013] According to a first particular embodiment of the translational-rotational fitting according to the invention, the blocking area of ​​the locking element is rod-shaped and can be inserted through an opening in the first fitting plate and in the second fitting plate into a positioning dome received in a recess of a base support plate or top support plate of the interface or of the second body.

[0014] The outer contour of the blocking area of ​​the locking element is positively engaged in the openings.

[0015] A safety element designed in this way is easy to manufacture and just as easy to install.

[0016] According to an advantageous embodiment, the gripping area of ​​the locking element is provided by an opening in the base or ceiling of the furniture component. If the locking element is not present, the opening in the base or ceiling can also be covered by a cover element.

[0017] This allows for easy access to the locking element, making both the installation and removal of the locking element simple.

[0018] According to a further embodiment of the invention, the grip area of ​​the locking element is connected to the blocking area via a joint, in particular in the form of a film hinge.

[0019] This allows for extremely compact packaging, as the handle of the locking element can be easily folded down after installation, either to the top of the base or, alternatively, to the underside of the top of the furniture component if the translational-rotation fitting is attached to the top of the furniture component. The handle can also be covered with a cover element. The foldable handle is also advantageous for the separate transport of the translational-rotation fitting itself, as the handle can be folded down to the top of the fitting.

[0020] According to an advantageous embodiment, at least one locking element is molded onto the blocking area for locking fixation to the first fitting plate or the second fitting plate.

[0021] This effectively prevents accidental disassembly or unintentional loosening of the locking element.

[0022] Depending on the design of the locking elements, the necessary disassembly force for removing the locking element from the fitting plates can also be easily adjusted.

[0023] According to a second design variant of a translational-rotational fitting, the blocking area of ​​the locking element is shaped like a strip and is fixed in the translational direction, but detachably fixed in the slide track.

[0024] According to an advantageous embodiment, the blocking area of ​​the locking element is installed with one end facing the other end of the slide.

[0025] In this version of the translational-rotation fitting, the locking element is clamped between the second fitting plate and the slide.

[0026] For ease of use, the handle area of ​​the locking element protrudes in the translational direction over an edge of the second fitting plate.

[0027] The grip area of ​​the safety element preferably has a ring-shaped piece that can be easily pulled up, for example by inserting a finger, in order to then pull the safety element out of the slide track.

[0028] According to an advantageous embodiment, at least one locking element is formed on the blocking area of ​​the locking element, which serves to lock it onto the second fitting plate.

[0029] This ensures that the locking element does not accidentally detach from the second fitting plate.

[0030] Furthermore, according to an advantageous embodiment, at least one groove is formed on the blocking area, into which a web protruding from the slide track projects.

[0031] This ensures that the safety element is easily secured in the translational direction within the sled track.

[0032] The furniture or household appliance element according to the invention comprises an interface and a furniture part movable relative to this interface, as well as a translational-rotational fitting with which the furniture part can be moved relative to the interface in a predetermined translational direction and simultaneously in one of two possible opposite rotational directions. The furniture part can, for example, be a first body or be designed as a table or platform for arranging several furniture parts. The interface can, for example, be a surface of a second body or other furniture, or even a building wall.

[0033] The translational-rotational fitting is designed as described above.

Fig. 19 one of the Fig. 18 corresponding illustration after horizontal removal of the safety element from the sled track and Fig. 20 one of the Fig. 18 corresponding illustration with the safety element completely removed from the sled track.

[0035] In the following figure descriptions, terms such as top, bottom, left, right, front, back, etc., refer exclusively to the exemplary representation and position of the translation-rotation fitting, fitting plates, locking element, slide, slide track, and the like as chosen in the respective figures. These terms are not to be understood as restrictive; that is, these references may change due to different working positions, mirror-symmetrical design, or similar factors.

[0036] In Fig. Reference numeral 1 denotes a total embodiment of a furniture or household appliance element according to the invention.

[0037] The furniture or household appliance element 1 has a first movable body 2 as a movable furniture part with a side wall 21, a base 22 and an opening 24 in the base 22, which serves to mount and dismount a safety element 130 which is yet to be described.

[0038] The furniture or household appliance element 1 further comprises a fixed second body 3 as a boundary surface, with one or more side walls 31, a base support plate 32 which extends both under the second body 3 and under the first body 2.

[0039] In this base support plate 32, as in Fig. Figure 9 shows at least one, preferably several, recesses 33 which serve to fix a translational-rotational fitting 100.

[0040] Positioning domes 160 are preferably fixed in the recesses 33, with which a second fitting plate 120 is fixed to the base support plate 32.

[0041] As in Fig. As shown in Figure 4, a translational-rotational fitting 100 is attached to an underside 23 of the base 22 of the first body 2, specifically with its first fitting plate 110.

[0042] The translational-rotation fitting 100, shown as a single illustration in the Fig. 5 and Fig. 6, serves the at least partially forced simultaneous translational-rotational movement of the first corpus 2 relative to the second corpus 3 in one of two in Fig. 1 opposite directions of rotation R1, R2 and in a similarly shown Fig. 1. Predetermined translation direction A.

[0043] The translational-rotational fitting 100 has the first fitting plate 110 which can be attached to the first body 2 and a second fitting plate 120 which can be attached to the second body 3 and which can be moved translationally and rotationally to the first fitting plate 110.

[0044] For transport securing of the furniture or household appliance element 1 or for assembly of the first body 2 and second body 3, the translational-rotation fitting 100 has the locking element 130 which can be detachably attached to the first fitting plate 110 and / or the second fitting plate 120, which in the assembled state fixes the fitting plates 110, 120 by blocking the translational movement relative to each other.

[0045] The functionality of the translational-rotation fitting 100 is described in principle in the subsequently published DE 10 2023 100 625.

[0046] An important component of the present invention is a slide 140 of the translational-rotation fitting 100, which is guided along a slide track 121 extending in the translational direction A, wherein the slide track 121 is arranged on the second fitting plate 120.

[0047] The safety element 130, shown as a separate illustration in the Fig. 7 and Fig. 8, has a grip area 131 and a blocking area 132 fixing the sled 140 in the starting position of the sled track 121.

[0048] The blocking area 132 of the locking element 130 is rod-shaped, preferably with a cylindrical body 135, and can be inserted through an opening 112, 122 in the first fitting plate 110 and in the second fitting plate 120 into a positioning dome 160 received in a recess 33 of the base support plate 32 (or also a cover support plate of the second body 3).

[0049] The outer contour of the blocking area 132 is positively engaged in the openings 112, 122 and thus ensures that the slide 140 is fixed in the plane of the fitting plates 110, 120 which are movable translationally and rotationally relative to each other.

[0050] As in the Fig. As shown in Figures 1 to 4, the grip area 131 of the locking element 130 passes through an opening 24 in the base 22 (or a ceiling) of the first body 2.

[0051] The grip area 131 is, as in the Fig. As can be seen further in sections 5 to 8, the handle area 131 is preferably connected to the locking area 132 via a joint 133, in particular in the form of a film hinge. Alternatively, the handle area 131 can also be connected to the locking area 132 by a detachable plug connection, and the handle area 131 can be removed from the furniture or household appliance element 1 after deactivation of the transport lock. In this case, the opening 24 in the base 22 or in the ceiling can be covered by a removable cover.

[0052] During the Fig. 7 and Fig. In the embodiment shown in Figure 8, the handle area 131 has a flat handle 137 adjoining the joint 133 and a head 136 adjoining the handle 137.

[0053] This shows how a comparison of Fig. 5 and Fig. Figure 6 shows the possibility that the locking element 130 can be folded down before the translation-rotation fitting 100 is mounted on the first body 2, thus not excessively increasing the height of the translation-rotation fitting 100.

[0054] What next in the Fig. 7 and Fig. As shown in Figure 8, at least one locking element 134 is formed on the blocking area 132 of the locking element 130; in the illustrated embodiment, two such locking elements 134 are located on opposite sides of the lateral surface of the body 135.

[0055] The locking elements 134 serve to lock the first fitting plate 110 in place, as shown in Fig. 4 can be seen. A (further) locking mechanism on the second fitting plate 120 is also conceivable.

[0056] Based on the Fig. Sections 9 to 12 describe the assembly process of the first body 2 on the second body 3 and the translation-rotation fitting 100.

[0057] Fig. Figure 9 shows the second, stationary body 3 with base support plate 32 and the translational-rotation fitting 100 before its mounting on the base support plate 32.

[0058] Fig. Figure 10 shows the first body 2 with base 22 and underside 23 of the base 22, into which the translational-rotational fitting 100 is inserted. The two positioning domes 160 attached to the second fitting plate 120 of the translational-rotational fitting 100 can be seen here. These domes are inserted into the recesses 33 in the base support plate 32 of the second body 3 and fixed there. One of these positioning domes 160 preferably also forms a counter bearing for the locking element 130.

[0059] Fig. Figure 11 shows again the first body 2 and the translational-rotational fitting 100 arranged below it with the locking element 130 already mounted, the handle area 131 of which is in Fig. 11 can be seen and is to be carried out into the opening 24 in the base 22 of the first body 2.

[0060] Fig. Figure 12 finally shows the translation-rotation fitting 100 arranged on the underside 23 of the base 22 of the first body 2, which only needs to be placed on the second body 3, whereby the positioning domes 160 are then received in the recesses 33 in the base support plate 32 of the second body 3 and thus position the translation-rotation fitting 100 and thus also the first body 2 in the predetermined position relative to the second body 3.

[0061] In the Fig. Figures 13 to 20 show an alternative design variant of a translational-rotational fitting 200, with an alternatively designed locking element 230.

[0062] In this version as well, the locking element 230 is attached to the slide 240, as shown in the Fig. 14 to 15 and 18 to 20, in a starting position of a sled track 221, a locking element is formed.

[0063] The sled track 221 is also formed on a second fitting plate 220. Running grooves 250 are arranged on the facing sides of the first fitting plate 210 and the second fitting plate 220, in particular formed, as shown in the Fig. 13 and Fig. 15 is shown.

[0064] The alternative locking element 230 suitable for this translational-rotational fitting 200 has, as shown in the Fig. 16 and Fig. 17 shown in the individual illustrations there, a grip area 231 and a blocking area 232 fixing the sled 240 in the starting position of the sled track 221.

[0065] The blocking area 232 of the locking element 230 is preferably designed in the form of a strip and is fixed in the translational direction A, but detachably fixed in the slide track 221.

[0066] For the fixed but detachable fixing of the locking element 230 in the sled track 221, the blocking area 232 of the locking element 230 with a front end 235 of a blocking body 234 abuts a front end 241 of the sled 240.

[0067] The other end face of the slide 240 is held in the starting position against a wall of the second fitting plate 220, or the movement of the slide 240 is limited by this wall of the second fitting plate 220.

[0068] For locking the second fitting plate 220, at least one locking element 236 is formed on the blocking area 232. This locking element 236 is shaped approximately like a hook and, when mounted, engages underneath, as shown in the Fig. 14 and Fig. As shown in 15, a bridge of the second fitting plate 220.

[0069] A further groove 239 is preferably provided between the locking area 232 and the gripping area 231 of the locking element, which allows elastic bending of the gripping area 231 relative to the locking area 232.

[0070] What next in the Fig. 14 and Fig. As shown in Figure 15, the grip area 231 of the locking element 230 projects in translational direction A over an edge of the second fitting plate 220.

[0071] For easy handling of the grip area 231 of this locking element 230, it has a ring piece 233 which can be easily gripped by an operator inserting a finger through it, and in particular for disassembly, as shown by the Fig. As shown in Figures 18 to 20, it is possible to easily lift the locking element 230 and then pull it out in translational direction A.

[0072] To further secure the locking element in the translational direction A, at least one groove 237 is formed on the blocking area 232, into which a web 222 protrudes from the slide track 221.

[0073] The locking element 236 is preferably designed as the second fitting plate 220 with an undercut.

[0074] To remove the locking element 230 from the clamping position that clamps the slide 240 in its slide track 221, proceed as indicated by the arrow in Fig. 18, the locking element 230 was first slightly lifted, thereby pulling the groove 237 out of the web protruding from the slide track 221.

[0075] At the same time, the elastic locking element 236 is released from its rear grip with the bridge of the second fitting plate 220.

[0076] Then, as in Fig. As shown in Figure 19, the locking element 230 is pulled out of the slide track 221 in translational direction A and finally, as in Fig. 20 shown, completely removed from toboggan run 221.

[0077] The locking element 130 or 230 allows the translational rotary fitting 100 or 200 to be secured against unintentional movement of the fitting parts relative to each other during transport, even without a furniture or household appliance element 1.

[0078] In another application scenario, it is conceivable that the locking element is only inserted after the translational-rotation fitting 100 has been removed from its packaging. In this case, the packaging provides complete transport protection. The locking element, e.g., in the form of a pin, is inserted by the installer immediately before assembly to ensure that the fitting remains in its installed position during installation.
