Description
[0001] Translation-rotation fitting and furniture or household appliance element
[0002] The present invention relates to a translation-rotation fitting according to the preamble of claim 1 and to a furniture or household appliance element according to the preamble of claim 14.
[0003] Translation-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 translation direction, in order to move the first body, for example, from a corner area from an initial position to a position rotated by 90° or a multiple of 90°, without striking the walls defining the corner area.
[0004] When transporting furniture equipped with such translation-rotation fittings, it is necessary to secure the furniture part that can be moved via the respective translation-rotation fitting, for example, the first carcass, to prevent accidental movement of this furniture part during transport. Even if the translation-rotation fitting is transported separately, it is advantageous to prevent movement of the two fitting plates to prevent damage. Furthermore, it is advantageous if the translation-rotation fitting is secured against accidental movement of the fitting parts relative to each other before installation.
[0005] The object of the present invention is therefore to further develop a translational-rotational fitting such that unintentional movement of the furniture part or of one of the fitting plates 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 parts relative to each other prior to assembly.
[0006] This object is achieved by a translation-rotation fitting with the features of claim 1. The translation-rotation fitting according to the invention for the at least partially forced simultaneous translation-rotation movement of a furniture part, 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 translation direction has a first fitting plate that can be fastened to the furniture part and a second fitting plate that can be fastened to the interface or the second body and can be moved simultaneously in translation and rotation relative to the first fitting plate. The furniture part can also be designed, for example, as a table, a platform for arranging several furniture parts, or another furniture element. The interface can also be, for example, a wall surface of a building wall.
[0007] The translation-rotation fitting further comprises a securing element that can be releasably fastened to the first fitting plate and / or the second fitting plate, wherein in the mounted state of the securing element the fitting plates are fixed relative to one another by blocking the translational movement.
[0008] With such a translation-rotation fitting, safe assembly and safe transport of a piece of furniture equipped with such a translation-rotation fitting is made possible in a simple manner.
[0009] Advantageous embodiments of the invention are the subject of the subclaims.
[0010] According to an advantageous embodiment of the invention, the translation-rotation fitting comprises at least one carriage guided on the second fitting plate along at least one carriage track extending in the translation direction, which carriage is rotationally coupled to the first fitting plate. The securing 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 can be prevented at the same time, since the translational movement of the translational-rotational fitting is accompanied by the rotational movement, and thus, 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 translation-rotation fitting according to the invention, the securing element has a gripping area and a blocking area that fixes the slide in the starting position of the slide track.
[0013] According to a first particular embodiment of the translation-rotation fitting according to the invention, the blocking region of the securing 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 cover support plate of the interface or the second body.
[0014] The outer contour of the blocking area of the securing element is positively received 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 development, the gripping area of the securing element passes through an opening in a floor or ceiling of the furniture part. The opening in a floor or ceiling can also be covered by a cover element if the securing element is not present.
[0017] This allows easy accessibility of the securing element, which allows both assembly and disassembly of the securing element to be carried out in a simple manner.
[0018] According to a further development of the invention, the gripping area of the securing 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 area of the securing element can be easily folded over after installation and thus attached to the upper side of the floor, or alternatively, to the underside of the ceiling of the furniture part if the translation-rotation fitting is attached to the ceiling of the furniture part. Here, too, the handle area can be covered by a cover element. The foldability of the handle is also advantageous for the separate transport of the translation-rotation fitting itself, as the handle can be folded over to the upper side of the translation-rotation fitting.
[0020] According to an advantageous further development, at least one locking element is formed on the blocking area for locking fixation on the first fitting plate or the second fitting plate.
[0021] This effectively prevents accidental disassembly or unintentional release of the locking element.
[0022] Depending on the design of the locking elements, the disassembly force required to remove the locking element from the fitting plates can also be easily adjusted.
[0023] According to a second embodiment of a translation-rotation fitting, the blocking area of the securing element is strip-shaped and is fixed in the translation direction in a stationary but releasable manner in the slide track.
[0024] According to an advantageous further development, the blocking area of the securing element is installed with a front end adjacent to a front end of the slide.
[0025] In this version of the translation-rotation fitting, the locking element is clamped between the second fitting plate and the carriage.
[0026] For easy operation, the handle area of the locking element protrudes in the translation direction over an edge of the second fitting plate.
[0027] The gripping area of the securing element preferably has a ring piece that can be easily pulled up, for example, by inserting a finger through it, and then withdrawn from the slide track. According to an advantageous development, at least one locking element is formed on the blocking area of the securing element, which serves to lock it into place on the second fitting plate.
[0028] This ensures that the locking element does not accidentally detach from the second fitting plate.
[0029] Furthermore, according to an advantageous embodiment variant, at least one groove is formed on the blocking area, into which a web protruding from the slide track protrudes.
[0030] This ensures that the safety element is easily secured in the translation direction in the slide track.
[0031] The furniture or household appliance element according to the invention comprises an interface and a furniture part movable relative to the interface, as well as a translation-rotation fitting with which the furniture part can be moved relative to the interface in a predetermined translation direction and simultaneously in one of two possible opposite rotation directions. The furniture part can be, for example, a first body or also designed as a table or platform for arranging multiple furniture parts. The interface can be, for example, a surface of a second body or other piece of furniture, or even a building wall.
[0032] The translation-rotation fitting is designed as described above.

[0050] 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 translation-rotation fitting, the fitting plates, the locking element, the slide, the slide track, 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 working positions or the mirror-symmetrical design, etc.
[0051] In Figure 1, the reference number 1 denotes an embodiment variant of a furniture or household appliance element according to the invention.
[0052] 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 assemble and disassemble a securing element 130 to be described below.
[0053] The furniture or household appliance element 1 further comprises a fixed second body 3 as an interface, with one or more side walls 31, and a base support plate 32 extending under both the second body 3 and the first body 2. As shown in Figure 9, at least one, preferably several, recesses 33 are provided in this base support plate 32, which serve to fix a translation-rotation fitting 100.
[0054] Positioning domes 160 are preferably fixed in the recesses 33, with which a second fitting plate 120 is fixed to the floor support plate 32.
[0055] As shown in Figure 4, a translation-rotation fitting 100 is attached to an underside 23 of the base 22 of the first body 2, namely with its first fitting plate 110.
[0056] The translation-rotation fitting 100, shown as an individual representation in Figures 5 and 6, serves for the at least partially forced simultaneous translation-rotation movement of the first body 2 relative to the second body 3 in one of two opposite directions of rotation Ri, R2 shown in Figure 1 and in a predetermined translation direction A also shown in Figure 1.
[0057] The translation-rotation fitting 100 has the first fitting plate 110 which can be fastened to the first body 2 and a second fitting plate 120 which can be fastened to the second body 3 and can be moved simultaneously in a translational and rotational manner relative to the first fitting plate 110.
[0058] To secure the furniture or household appliance element 1 during transport or to assemble the first body 2 and second body 3, the translation-rotation fitting 100 has the securing element 130 which can be releasably fastened to the first fitting plate 110 and / or the second fitting plate 120 and which, in the assembled state, fixes the fitting plates 110, 120 relative to one another by blocking the translational movement.
[0059] The principle of operation of the translation-rotation fitting 100 is described in the subsequently published DE 10 2023 100 625.
[0060] An important component for the present invention is a carriage 140 of the translation-rotation fitting 100, which is guided along a carriage track 121 extending in the translation direction A, wherein the carriage track 121 is arranged on the second fitting plate 120. The securing element 130, shown as an individual illustration in Figures 7 and 8, has a gripping region 131 and a blocking region 132 that fixes the carriage 140 in the starting position of the carriage track 121.
[0061] The blocking region 132 of the securing element 130 is here 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 in the base support plate 32 (or also a cover support plate of the second body 3).
[0062] The outer contour of the blocking area 132 is positively received in the openings 112, 122 and thus ensures that the carriage 140 is fixed in the plane of the fitting plates 110, 120, which are movable in translation and rotation relative to one another.
[0063] As further shown in Figures 1 to 4, the gripping portion 131 of the securing element 130 passes through an opening 24 in the bottom 22 (or a ceiling) of the first body 2.
[0064] The handle area 131 is, as can be further seen in Figures 5 to 8, preferably connected to the blocking 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 blocking area 132 via 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.
[0065] In the embodiment shown in Figures 7 and 8, the handle area 131 has a flat handle 137 adjoining the joint 133 and a head 136 adjoining the handle 137.
[0066] As a comparison of Figures 5 and 6 shows, this provides the possibility of folding the securing element 130 before mounting the translation-rotation fitting 100 on the first body 2, thus preventing the height of the translation-rotation fitting 100 from being excessively increased. As further illustrated in Figures 7 and 8, at least one locking element 134 is formed on the blocking area 132 of the securing element 130; in the illustrated embodiment, two such locking elements 134 are formed on opposite sides of the outer surface of the body 135.
[0067] The locking elements 134 serve to lock the first fitting plate 110, as can be seen in Figure 4. A (further) locking fixation on the second fitting plate 120 is also conceivable.
[0068] The assembly process of the first body 2 on the second body 3 and the translation-rotation fitting 100 is described with reference to Figures 9 to 12.
[0069] Figure 9 shows the second, fixed body 3 with base support plate 32 and the translation-rotation fitting 100 before its assembly on the base support plate 32.
[0070] Figure 10 shows the first body 2 with the base 22 and the underside 23 of the base 22, into which the translation-rotation fitting 100 is inserted. The translation-rotation fitting 100 shows the two positioning domes 160 attached to the second fitting plate 120, which 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 counterbearing for the securing element 130.
[0071] Figure 11 again shows the first body 2 and the translation-rotation fitting 100 arranged underneath with the already mounted securing element 130, the grip area 131 of which can be seen in Figure 11 and which is to be inserted into the opening 24 in the base 22 of the first body 2.
[0072] Finally, Figure 12 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, wherein 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. Figures 13 to 20 show an alternative embodiment of a translation-rotation fitting 200, with an alternatively designed securing element 230.
[0073] In this embodiment variant, the securing element 230 is also designed as a blocking element that fixes the slide 240, shown in Figures 14 to 15 and 18 to 20, in a starting position of a slide track 221.
[0074] Here, too, the slide track 221 is integrally formed on a second fitting plate 220. On the mutually facing sides of the first fitting plate 210 and the second fitting plate 220, grooves 250 are arranged, in particular integrally formed, as shown in Figures 13 and 15.
[0075] The alternative securing element 230 suitable for this translation-rotation fitting 200 has, as shown in the individual illustrations in Figures 16 and 17, a gripping area 231 and a blocking area 232 which fixes the carriage 240 in the starting position of the carriage track 221.
[0076] The blocking area 232 of the securing element 230 is preferably strip-shaped and is fixed in the translation direction A in a stationary but releasable manner in the slide track 221.
[0077] For the stationary but releasable fixation of the securing element 230 in the slide track 221, the blocking area 232 of the securing element 230 rests with a front end 235 of a blocking body 234 on a front end 241 of the slide 240.
[0078] The other front end of the slide 240 is held in the starting position on 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.
[0079] For locking fixation to 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, in the assembled state, as shown in Figures 14 and 15, engages under a web of the second fitting plate 220. A further groove 239 is preferably provided between the blocking area 232 and the grip area 231 of the securing element, which enables elastic bending of the grip area 231 relative to the blocking area 232.
[0080] As further shown in Figures 14 and 15, the gripping portion 231 of the securing element 230 projects in the translation direction A beyond an edge of the second fitting plate 220.
[0081] For easy handling of the grip area 231 of this securing element 230, it has a ring piece 233 which can be easily gripped by inserting a finger of an operator and, in particular for disassembly, as shown in Figures 18 to 20, enables the securing element 230 to be easily lifted and subsequently pulled out in the translation direction A.
[0082] To further secure the securing element in the translation 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.
[0083] The locking element 236 is preferably designed as an undercut engaging behind the second fitting plate 220.
[0084] To disassemble the securing element 230 from the clamping position clamping the carriage 240 in its carriage track 221, as indicated by the arrow in Figure 18, the securing element 230 is first slightly lifted and the groove 237 is pulled out of the web protruding from the carriage track 221.
[0085] At the same time, the elastic locking element 236 is released from its rear engagement with the web of the second fitting plate 220.
[0086] Subsequently, as shown in Figure 19, the securing element 230 can be pulled out of the slide track 221 in the translation direction A and finally, as shown in Figure 20, completely removed from the slide track 221.
[0087] The securing element 130 or 230 allows the translation
[0088] Rotation fitting 100 or 200 can be secured during transport against unintentional movement of the fitting parts relative to each other, even without a furniture or household appliance element 1.
[0089] 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 directly before installation so that the fitting remains in its installed position during assembly.
