Abstract

A translation-rotational fitting (100, 200) is disclosed, comprising: first fitting plates (110, 210) that can be attached to a furniture component, causing the furniture component to undergo a partially simultaneous forced translation-rotational movement with respect to an interface surface in one of two opposite rotational directions (R1, R2) and in a predetermined translational direction (A); and second fitting plates (120, 220) that can be attached to the interface surface and are moved simultaneously in translational and rotational directions relative to the first fitting plates (110, 210); and fixing elements (130, 230) that can be detachably fastened to the first fitting plates (110, 210) and / or the second fitting plates (120, 220); wherein when the fixing elements (130, 230) are attached, the fitting plates (110, 210) are fixed to each other by blocking translational and / or rotational movement. Furthermore, furniture or household appliances (1) are also listed.

Description

Technical Field

[0001] The present invention relates to a translational-rotational fitting described in the first part of claim 1 and a furniture or household appliance described in the first part of claim 14.

Background Art

[0002] This type of translational-rotational fitting is known, for example, from International Publication No. 2022 / 157295 or German Patent Publication No. 10 2019 109 866. These are used to move a first object relative to a boundary surface (for example, a second body) in either one of two opposite directions of rotation and simultaneously in a predetermined translational direction, and to move the first body, for example, from a corner region, to a position rotated by 90 degrees or a multiple thereof from an initial position, without contacting the wall defining the corner region.

[0003] When transporting furniture to which such a translational-rotational fitting is attached, in order to prevent this furniture part from moving unintentionally during transportation, it is necessary to fix each translational-rotational fitting, for example, a furniture part that can move through the first body. Even when transporting the translational-rotational fittings separately, it is advantageous to prevent the movement of the two fitting plates and prevent their damage. Furthermore, it is advantageous if the translational-rotational fitting is fixed before assembly so that the parts of the fitting do not move relative to each other unintentionally.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Therefore, an object of the present invention is to further develop a translational-rotational fitting such that an unwanted movement of a furniture part or a fitting plate is effectively prevented during transportation or assembly. A further object of the present invention is to fix the translational-rotational fitting before assembly so that the parts of the fitting do not move relative to each other unintentionally.

Means for Solving the Problems

[0005] This objective is achieved by a translation-rotation fitting having the features of claim 1.

[0006] A translation-rotation fitting according to the present invention, which forces a piece of furniture, for example, a first body, to undergo a partially simultaneous translational-rotational movement in one of two opposite rotational directions and in a predetermined translational direction relative to an interface, for example, a second body, comprises a first fitting plate that can be attached to a furniture component, and a second fitting plate that can be attached to the interface or the second body and can be moved simultaneously in a translational and rotational manner relative to the first fitting plate. The furniture component may be, for example, a table, a platform for arranging several pieces of furniture, or another furniture element. The interface may be, for example, a wall surface of a building.

[0007] The translation-rotation fitting further comprises a fixing element that can be detachably attached to the first fitting plate and / or the second fitting plate, thereby fixing the two fitting plates to each other by preventing the translational motion when the fixing element is attached.

[0008] A translation-rotational interlocking mechanism designed in this way allows for the safe assembly and transportation of furniture equipped with such an interlocking mechanism in a simple manner. Advantageous embodiments of the present invention are the subject matter of the dependent claims.

[0009] According to one advantageous embodiment of the present invention, the translation-rotation mating device comprises at least one carriage, which is guided along a second mating plate along at least one carriage track extending in the translational direction, and the carriage is rotatably connected to a first mating plate. The fixed element is designed as a locking element that fixes the slide in place at the starting position of the slide trajectory.

[0010] Blocking the slide with the help of a fixing element simultaneously prevents the entire translation-rotation motion, because the translational motion of a translation-rotation fitting is accompanied by rotational motion, and therefore sufficient fixing is achieved by blocking the translational motion. Alternatively or additionally, locking elements can also be used to lock rotational motion.

[0011] According to a further development of the translation-rotation fitting according to the present invention, the fixing element has a gripping region and a block region that fixes the slide at the starting position of the slide trajectory.

[0012] According to a first special embodiment of the translation-rotation mating device according to the present invention, the block region of the fixed element is designed in a rod-like form and is inserted through an opening in the first mating device plate and into a positioning dome that is received in a recess of the base support plate or the second body or top support plate of the interface within the second mating device plate.

[0013] The outer contour of the block region of the fixed element is received within the opening by a shape-fitting mechanism. Locking elements designed in this way are easy to manufacture and easy to install.

[0014] In a more advantageous further development, the gripping area of ​​the fixing element passes through an opening at the base or top of the furniture component. The opening at the base or top may be covered by a cover element when no fixing element is present. This allows for easy access to the fixed elements, and makes it easier to install and remove them.

[0015] According to a further improved embodiment of the present invention, the gripping region of the fixed element is connected to the block region via a joint, particularly in the form of a film hinge.

[0016] The gripping area of ​​the fixed element can be easily folded after installation, and therefore can be folded to the top of the base, or alternatively to the underside of the top of the furniture component, when the translation-rotation fitting is attached to the top of the furniture component, thus enabling extremely compact packaging. Here again, the gripping area can be covered by a cover element. Furthermore, since the handle can be folded onto the top of the translation-rotation fitting, the ability to fold the handle is also advantageous when transporting the translation-rotation fitting itself separately.

[0017] In a more favorable further development example, at least one locking element is molded onto a block region for locking and securing a first or second mating plate. This effectively prevents accidental disassembly or unintentional loosening of locking elements. The configuration of the locking element also allows for easy adjustment of the force required to remove the locking element from the mating plate.

[0018] According to a second embodiment of the translation-rotation fitting, the block region of the fixed element is designed in the form of a strip and is fixed in the translational direction but can be loosened within the sliding track. In a more advantageous example of development, the block region of the fixed element is positioned such that one end abuts against the other end of the slide.

[0019] In this embodiment of the translation-rotation mating device, the fixing element is fixed between the second mating plate and the slide. For ease of use, the gripping area of ​​the fixed element protrudes beyond the edge of the second fitting plate in the direction of translational motion. The gripping region of the fixed element preferably has a ring piece that allows the fixed element to be easily pulled up, for example by inserting a finger, in order to pull it out of the sliding trajectory.

[0020] According to a further advantageous development example, at least one retaining element is formed in the blocking region of the fixing element, and this blocking region functions for retaining and fixing to the second fitting plate. This ensures that the fixing element does not accidentally come off the second fitting plate.

[0021] Furthermore, according to an advantageous embodiment, at least one groove is formed on the blocking region, and a web protruding from the slide track protrudes into this groove. This fixes the fixing element in a simple manner in the translational direction within the slide track.

[0022] The furniture or household appliance according to the present invention has an interface surface, a furniture part that can move relative to this interface surface, and a translational-rotational fitting that allows the furniture part to move in a predetermined translational direction relative to the interface surface and simultaneously move in one of two opposite possible rotational directions. The furniture part can be, for example, a first body, or can also be configured as a table or platform for arranging several furniture parts. The interface surface can be, for example, the surface of a second body or another part of the furniture, or the wall of a building. The translational-rotational fitting is designed as described above.

[Figure 18] Corresponding to Figure 14, the second fitting plate with the fixing element attached is shown, and the fixing element is slightly lifted in order to remove it from the second fitting plate. [Figure 19]This diagram corresponds to Figure 18, and shows the state after the fixed element has been horizontally removed from the slide track. [Figure 20] The diagram corresponding to Figure 18 shows that the fixed element has been completely removed from the slide track. [Modes for carrying out the invention]

[0024] In the following description of the figures, terms such as up, down, left, right, front, and back refer exclusively to exemplary representations and positions of translation-rotation fittings, joint plates, fixing elements, slides, slide tracks, etc., as selected in each figure. These terms should not be understood as restrictive; i.e., these references may vary due to different working positions or mirror-symmetry designs, etc.

[0025] In Figure 1, reference numeral 1 denotes a modified design of furniture or household appliance according to the present invention. The furniture or household appliance 1 has a movable first body 2 as a movable furniture component, the first body having a side wall 21, a base 22, and an opening 24 within the base 22, the opening 24 serving to attach and detach a fixing element 130, which will be described later.

[0026] The furniture or household appliance 1 also has a second body 3 fixed as an interface, the second body 3 having one or more side walls 31 and a base support plate 32 extending both below the second body 3 and below the first body 2. As shown in Figure 9, at least one, preferably several, recesses 33 are provided in the base support plate 32, and the recesses 33 help to secure the translation-rotation fitting 100.

[0027] The positioning dome 160 is preferably fixed within the recess 33, and the second fitting plate 120 is fixed to the base support plate 32 using the recess 33. As shown in Figure 4, the translation-rotation fitting 100 has its first fitting plate 110 attached to the lower side 23 of the base 22 of the first body 2.

[0028] The translation-rotation fittings 100, shown separately in Figures 5 and 6, serve to at least partially bias the translation-rotation motion of the first body 2 relative to the second body 3 in one of two opposite rotation directions R1 and R2, and in a predetermined translation direction A, also shown in Figure 1.

[0029] The translation-rotation fitting device 100 includes a first fitting plate 110 that can be attached to the first body 2, and a second fitting plate 120 that can be attached to the second body 3 and is capable of moving simultaneously in translation and rotation relative to the first fitting plate 110.

[0030] For securing furniture or household appliances 1 during transport, or for assembling a first body 2 and a second body 3, the translation-rotation fitting 100 has a fixing element 130 that can be detachably attached to the first fitting plate 110 and / or the second fitting plate 120, the fixing element fixing the fitting plates 110 and 120 in an assembled state by blocking their translational motion relative to each other when the fitting plates 110 and 120 are assembled.

[0031] The operating modes of the translation-rotation fitting device 100 are, in principle, described in German Patent Publication No. 10 2023 100 625, which was published thereafter. An important component of the present invention is the slide 140 of the translation-rotation fitting 100, which is guided along a slide track 121 extending in the translation direction A, where the slide track 121 is located on a second fitting plate 120.

[0032] The fixing element 130 is shown individually in Figures 7 and 8 and has a gripping region 131 and a block region 132 that fixes the slide 140 at the starting position of the slide trajectory 121.

[0033] The block region 132 of the fixing element 130 is preferably a rod-shaped structure formed of a cylindrical body 135, passing through openings 112 and 122 in the first fitting plate 110 and extending into the positioning dome 160, which is received in the recess 33 of the base support plate 32 (or the top support plate of the second body 3) within the second fitting plate 120.

[0034] The outer contour of the block region 132 is received in a shape-fitting manner within the openings 112, 122, so that the slide 140 is fixed within the planes of the fitting plates 110, 120, which can move translationally and rotationally relative to each other. As further shown in Figures 1 to 4, the gripping region 131 of the fixing element 130 passes through the opening 24 of the base 22 (or top) of the first body 2.

[0035] As can be seen from Figures 5 to 8, the gripping area 131 is preferably connected to the block area 132 via a joint 133, particularly in the form of a film hinge. Alternatively, the gripping area 131 may also be connected to the block area 132 by a removable plug connection, and the gripping area 131 can be removed from the furniture or household appliance 1 after the transport lock is stopped. In this case, the base 22 or the upper opening 24 can be covered by a removable cover.

[0036] In the embodiments shown in Figures 7 and 8, the gripping region 131 has a flat handle piece 137 connected to the joint 133 and a head 136 connected to the handle piece 137. As can be seen by comparing Figures 5 and 6, this allows the fixing element 130 to be folded before attaching the translation-rotation fitting 100 to the first body 2, and thus prevents the height of the translation-rotation fitting 100 from increasing excessively.

[0037] As further shown in Figures 7 and 8, at least one locking element 134 is formed on the block region 132 of the fixed element 130, and in the shown embodiment, two such locking elements 134 are formed on both sides of the outer surface of the body 135. As shown in Figure 4, the locking element 134 serves to lock the fitting into a predetermined position on the first fitting plate 110, and it is also conceivable that there be an (additional) locking element on the second fitting plate 120.

[0038] Figures 9 to 12 show the process of assembling the first body 2 with the second body 3 and the translation-rotation fitting 100. Figure 9 shows a fixed second body 3 comprising a base support plate 32 and a translation-rotation fitting 100 before it is assembled on the base support plate 32.

[0039] Figure 10 shows a first body 2 having a base 22 and a lower part 23 of the base 22 into which a translation-rotation fitting 100 is inserted. This translation-rotation fitting 100 shows two positioning domes 160 attached to a second fitting plate 120, which are inserted into and fixed in a recess 33 of the base support plate 32 of the second body 3. Preferably one of these positioning domes 160 also forms a corresponding bearing for a fixing element 130.

[0040] Figure 11 shows the first body 2 and the translation-rotation fitting 100 positioned below the first body 2, with the fixing element 130 already attached, the gripping area 131 of which can be seen in Figure 11, and is inserted into the opening 24 of the base 22 of the first body 2.

[0041] Finally, Figure 12 shows a translation-rotation fitting 100 positioned on the lower side 23 of the base 22 of the first body 2. This translation-rotation fitting only needs to be placed on the second body 3, thereby the positioning dome 160 is then received into the recess 33 of the base support plate 32 of the second body 3, and thus the translation-rotation fitting 100 is positioned, and thus the first body 2 is also positioned in a predetermined position relative to the second body 3.

[0042] Figures 13 to 20 show alternative design variations of the translation-rotation fitting 200 having alternatively designed fixed elements 230. In this modified design, the fixing element 230 is designed as a block element that fixes the slide 240 shown in Figures 14 to 15 and Figures 18 to 20 at the starting position of the slide trajectory 221.

[0043] Here too, the slide track 221 is formed on the second fitting plate 220. The running groove 250 is positioned and specifically formed on the opposing sides of the first fitting plate 210 and the second fitting plate 220, as shown in Figures 13 and 15. An alternative fixing element 230 suitable for this translation-rotation fitting 200 has a gripping area 231 and a blocking area 232 that fixes the slide 240 to the starting position of the slide track 221, as shown in the individual figures of Figures 16 and 17.

[0044] The block region 232 of the fixed element 230 is preferably designed in the form of a strip and is fixed in the translational direction A, but can be released from the sliding track 221. To fix the fixed element 230 within the slide track 221 but to allow it to be released, the block region 232 of the fixed element 230 has its front end 235 of the block body 234 resting on the front end 241 of the slide 240.

[0045] The other front end of the slide 240 is held in an initial position on the wall surface of the second fitting plate 220, or the movement of the slide 240 is restricted by the wall surface of the second fitting plate 220. At least one retaining element 236 is formed on the block region 232 to lock the fixation to the second mating plate 220. This retaining element 236 is hook-shaped and, when installed, engages under the web of the second mating plate 220, as shown in Figures 14 and 15.

[0046] Preferably, an additional groove 239 is provided between the block region 232 and the gripping region 231 of the fixed element, thereby enabling elastic bending of the gripping region 231 relative to the block region 232. As further shown in Figures 14 and 15, the gripping region 231 of the fixing element 230 protrudes in the translational direction A beyond the edge of the second fitting plate 220.

[0047] To facilitate handling of the gripping area 231 of the fixed element 230, the fixed element 230 has a ring piece 233 that can be easily gripped by inserting the operator's fingers, and in particular, as shown in Figures 18 to 20, the fixed element 230 can be easily lifted and then pulled out in the translational direction A.

[0048] To further secure the fixed element in direction A of translational motion, at least one groove 237 is formed on the block region 232 into which a web 222 protruding from the slide track 221 protrudes. The retaining element 236 is preferably designed as an undercut that engages behind the second mating plate 220.

[0049] As shown by the arrows in Figure 18, to remove the fixing element 230 from the clamp position that secures the slide 240 to the slide track 221, first lift the fixing element 230 slightly and pull the groove 237 out of the web protruding from the slide track 221. At the same time, the elastic retaining element 236 is released from rearward engagement with the web of the second fitting plate 220.

[0050] Next, as shown in Figure 19, the fixed element 230 is pulled out of the sliding track 221 in the translational direction A, and finally, as shown in Figure 20, it can be completely removed from the sliding track 221. The fixing elements 130 or 230 may be used to secure the translation-rotation fitting 100 or 200 during transport, even without the furniture or household appliance 1, to prevent the fitting's components from moving undesirably toward each other.

[0051] In another application scenario, the fixing element may be inserted only after the translation-rotation mating fixture 100 has been removed from its packaging. In this case, the packaging provides complete protection during transport. For example, the fixing element in the form of a pin is inserted by the installer immediately before assembly, and as a result, the mating fixture remains in its installation position during assembly.
