[0001] Translation-rotation arrangement and furniture or household appliance element
[0002] The present invention relates to a translation-rotation arrangement for a piece of furniture, a household appliance or a group of furniture and / or household appliances of a modular interior design system for rooms according to the preamble of claim 1 and to a furniture or household appliance element according to the preamble of claim 3.
[0003] Generic furniture or household appliance elements or translation-rotation arrangements for furniture or household appliances serve to simplify access to hard-to-reach areas in a storage space of the furniture or household appliance element or also the variable arrangement of furniture or household appliances in a group of such furniture and / or household appliances of a modular interior design system for rooms or the variable positioning of the group as a whole in a room.
[0004] The simultaneous translational and rotational movement of the furniture or household appliance element, or of such a translational-rotational arrangement, is achieved by arranging a translational-rotational fitting between a first body of the furniture and a second body of the furniture that is movable relative to the first body. Alternatively, the relative movement can also occur between a movable body of the furniture and the ceiling and / or floor of the room.
[0005] In a translation-rotation arrangement, the translation-rotation movement is achieved, for example, by guide cam tracks in storage areas of a base and a support element arranged thereon, wherein the group of furniture and / or household appliances is placed on the support element.
[0006] Such a translation-rotation arrangement is known, for example, from WO 2021 / 001395 A1 or WO 2020 / 212373 A1. A problem with such components that can be moved relative to one another is the supply of electrical energy to electrical devices that are housed in the translationally and rotationally moving support element or second body.
[0007] The object of the present invention is to further develop a translation-rotation arrangement for a piece of furniture or household appliance or a group of furniture and / or household appliances of a modular interior design system for rooms as well as a furniture or household appliance element in such a way that they can be easily equipped with a power supply in the translationally and rotationally moved support element or second body.
[0008] This object is achieved by a translation-rotation arrangement for a piece of furniture, a household appliance or a group of furniture and / or household appliances of a modular interior design system for rooms having the features of claim 1 and by a furniture or household appliance element having the features of claim 3.
[0009] The translation-rotation arrangement according to the invention for a piece of furniture, a household appliance or a group of furniture and / or household appliances of a modular interior design system for rooms comprises a base and a support element with mutually facing flat storage areas.
[0010] The support element is mounted relative to the base so that it can move at least partially simultaneously in translation and rotation.
[0011] In one of the bearing areas, guide cam tracks are arranged and in the other of the bearing areas, guide elements guided in or on the contours of the guide cam tracks are arranged, so that the support element is at least partially forced to rotate relative to the base in one of two possible opposite directions of rotation and movable in a predetermined direction of translation.
[0012] The guide cam tracks are shaped in such a way that when a moment acts on the support element, the support element can be moved from an initial position via an intermediate position in which the support element is rotated relative to the base in one of two possible opposite directions of rotation and displaced in the translation direction, by further rotating in one of two possible opposite directions of rotation and displacing against the translation direction into an end position congruent with the initial position.
[0013] A guide groove extending in the translational direction is arranged in the base. A guide element protruding into the guide groove is arranged in the bearing area of the support element. Alternatively, the guide groove can also be arranged in the bearing area of the support element, and the guide element can be arranged in the base.
[0014] The guide element is designed as a rotary union.
[0015] A first power connection element is attached to a side of the base facing away from the bearing area of the base, and a second power connection element is attached to a side of the support element facing away from the bearing area of the support element.
[0016] The power connection elements are connected to each other via a power cable that runs through the rotary union.
[0017] The furniture or household appliance element according to the invention comprises a first body and a second body movable relative to the first body.
[0018] The furniture or household appliance element further comprises a translation-rotation fitting with which the second body can be moved relative to the first body in a predetermined translation direction and at least partially simultaneously in one of two possible opposite rotation directions.
[0019] The translation-rotation fitting has a first fitting plate coupled to the first body and a second fitting plate coupled to the second body and movable at least partially simultaneously in translation and rotation relative to the first fitting plate.
[0020] In an overlap area of a base or cover plate of the first body with the second body in a closed position of the second body, a recess is provided in the base or cover plate of the first body through which a power cable is passed. The power cable is connected at a first end to a power connection element that is attached to a side of the second body facing the base or cover plate of the first body. The recess can also be designed in the form of a bore.
[0021] Both with the translation-rotation arrangement and with the furniture or household appliance element, the arrangement described above ensures a simple power supply to electrical consumers that are positioned or placed in the translationally and rotationally movable second body or on or in the support element.
[0022] In addition to a first body conventionally used as a supporting body with a base plate, cover plate and at least one side wall, the second body, which is mounted at least partially so as to be movable both translationally and rotationally at the same time, can be fixed directly to a room wall only via a base plate and a cover plate which form the first body.
[0023] Advantageous embodiments of the invention are the subject of the subclaims.
[0024] According to an advantageous embodiment of the arrangement according to the invention, the first power connection element is fastened to the base laterally of the guide groove and, viewed in the longitudinal extension of the guide groove, approximately centrally offset in parallel.
[0025] This positioning of the first power connection element allows for a possible small variance of the distance between the first power connection element and the translationally moving guide sleeve.
[0026] According to an advantageous embodiment of the furniture or household appliance element according to the invention, the recess has a through-opening, a groove-shaped cable duct open to the second body and a flat depression adjoining the cable duct and open to the second body.
[0027] According to an alternative embodiment of the furniture or household appliance element according to the invention, the recess is designed as a guide groove for the power cable. According to a further alternative embodiment of the furniture or household appliance element according to the invention, the recess is designed as a bore.
[0028] All variants ensure that the power cable can move freely in the recess area with the translational-rotational movement of the second body.
[0029] According to a further advantageous embodiment of the arrangement or of the furniture or household appliance element, at least one of the power connection elements has a winding mechanism with a cable storage area onto which a section of the power cable can be wound or unwound during the translational-rotational movement of the second body or the support element.
[0030] Such a winding mechanism also prevents the power cable from becoming pinched or knotted during the movement of the second body or the support element.
[0031] According to an alternative embodiment, the power cable is designed at least in sections as a spiral cable or as a cable loop and thus enables in particular the length extension of the power cable required by the translational movement.
[0032] According to a further advantageous embodiment, the power cable is guided at least in sections in an energy chain.
[0033] This additionally protects the power cable from being pinched or similar during the movement of the components that can be moved relative to one another.

[0052] In the following description of the figures, terms such as top, bottom, left, right, front, back, etc. refer exclusively to the exemplary representation and position of the furniture or household appliance element, translation-rotation fitting, base, support element, first body, second body, and the like chosen in the respective figures. These terms are not to be understood as limiting, i.e., these references can change due to different working positions or the mirror-symmetrical design or the like. In the following, an embodiment variant of a translation-rotation arrangement according to the invention for a piece of furniture, household appliance, or a group 11 of furniture and / or household appliances of a modular interior design system for rooms is described with reference to Figures 1-8.
[0053] The further figures 9-16 serve to explain a further embodiment variant of a furniture or household appliance element 100 according to the invention.
[0054] Such a group 11 of furniture or household appliances of a modular interior design system for rooms is shown as an example in Figure 8.
[0055] As can be seen here, the entire group 11 of furniture and / or household appliances is placed on a supporting element 3 which is mounted on a base 2.
[0056] As an example of the group 11 of furniture, a shelf 12, a chair 13 and a table 14 are shown in Figure 8 placed on the support element 3, which, by means of translational-rotational movement of the support element 3 relative to the base 2, enables the group 11 of furniture to be aligned in the room, for example rotated by an angle of 90°.
[0057] As shown in Figures 1-7, the base 2 and the support element 3 have mutually facing flat bearing areas 21, 31. As mentioned above, the support element 3 is mounted so that it can be moved both translationally and rotationally relative to the base 2.
[0058] For this purpose, guide cam tracks 22 are arranged in one of the bearing areas 21, 31 of the base 2 or the support element 3, and guide elements 4 guided in or on the contours of the guide cam tracks 22 are arranged in the other of the bearing areas 21, 31.
[0059] This enables the support element 3 to be at least partially forced to rotate relative to the base 2 in one of two possible opposite directions of rotation Ri, R2 and to be movable in a predetermined translation direction A.
[0060] The movement in the translation direction A is additionally guided by a guide groove 23 extending in the translation direction A in the base 2 and a guide element projecting into the guide groove 23 on the bearing area 31 of the support element 3. The guide element is designed as a rotary union 5.
[0061] The guide cam tracks 22 are further shaped in such a way that when a moment acts on the support element 3, the support element 3 can be moved from an initial position via an intermediate position in which the support element 3 is rotated relative to the base 2 in one of two possible opposite directions of rotation Ri, F and displaced in the translation direction A, by further rotating in one of two possible opposite directions of rotation Ri, R2 and displacing opposite to the translation direction A into an end position congruent with the initial position.
[0062] In order to enable a power supply to furniture and / or household appliances arranged on the support element 3 or to electrical consumers arranged on or in these, a first power connection element 6 is fastened on a side of the base 2 facing away from the support element 3 and a second power connection element 7 is fastened on an upper side of the support element 3 facing away from the base 2.
[0063] The two power connection elements 6, 7 are connected to each other via a power cable 8 passing through the rotary union 5. The power cable 8 is guided through a preferably cylindrical through-opening 51 of the rotary union 5, which forms a passage for the power cable from the side of the base 2 facing away from the support element 3 to the top side of the support element 3 facing away from the base 2.
[0064] As further shown in Figures 2-7, the first power connection element 6 is preferably connected via a further power cable 9 to a further power connection element 10, which is designed, for example, as a socket on the wall or on the floor of a room.
[0065] Figures 3-7 illustrate a translational-rotational movement of the support element 3 relative to the base 2, with which the group 11 of furniture, as shown by way of example in Figure 8, can be positioned offset by 90° relative to the base 2.
[0066] By routing the power cable 8 through the through-opening 51 of the rotary union 5, a cable laying is possible which reliably connects the power connection elements 6, 7 arranged on the one hand on the base 2 and on the other hand on the support element 3, even during the translational-rotational movement of the support element 3 relative to the base 2.
[0067] The power cable 8 can preferably be designed as a spiral cable.
[0068] Alternatively, it is also conceivable for the power cable 8 to be dragged along during the translational-rotational movement of the support element 3 relative to the base 2.
[0069] As is illustrated by the different positioning of the support element 3 relative to the base 2 in Figures 3 - 7, the suitable arrangement of the first power connection element 6 fastened to the base 2 to the side of the guide groove 23 and the first power connection element 6 offset approximately centrally and parallel as viewed in the longitudinal extent of the guide groove 23 makes it possible for the required length of the power cable 8 to bridge the distance between the first power connection element 6 and the rotary feedthrough 5 to vary only slightly.
[0070] The distance between the rotary feedthrough 5 and the second power connection element 7 is determined by the fixing of the second power connection element 7 to the support element 3 by its distance from the rotary feedthrough 5, which is also fixed to the support element 3.
[0071] The guidance of the support element 3 on the base 2 via the guide cam tracks 22 and the guide elements 4 guided along or in these tracks is also not impaired by the power cable 8, since the power cable 8 is guided through the through-opening 51 of the rotary union 5. Figures 9-16 show a variant of a furniture or household appliance element 100 according to the invention.
[0072] The furniture or household appliance element 100 has a first body 110 and a second body 120 that is movable relative to the first body. As can be seen in Figure 10, the second body 120 is embodied here, by way of example, as a shelf with intermediate shelves closed on two sides by side walls, which is mounted next to a stationary first body 110 and is movable translationally and rotationally relative to the first body by means of a translation-rotation fitting 130. In the exemplary embodiment shown, a cover plate 150 is located above the first body 110, which also covers the second body 120 and on which a translation-rotation fitting 130 is also arranged for moving the second body 120.
[0073] The translation-rotation fitting 130 enables a relative movement to the first body 110 in a predetermined translation direction A and simultaneously in one of two possible opposite rotation directions Ri, R2.
[0074] The translation-rotation fitting 130 has a first fitting plate 131 coupled to the first body 110 and a second fitting plate 132 coupled to the second body 120 and simultaneously movable in translation and rotation relative to the first fitting plate 131.
[0075] For the power supply of power consumers arranged on or in the second body 120, a recess 160 is provided in an overlap area of a base or cover plate 140, 150, here the base plate 140 of the first body 110 with the second body 120 in a closed position of the second body 120 in the base or cover plate 140, 150 of the first body 110.
[0076] In the illustrated embodiment, the recess 160 is formed in the base plate 140 of the first body 110. A power cable 101 is passed through this recess 160 and is connected at a first end to a power connection element 170 that is attached to a side of the second body 120 facing the base or cover plate 140, 150 of the first body 110.
[0077] The recess 160 provided here in the base plate 140 has, as shown in particular in Figure 9, a through-opening 161, a groove-shaped cable duct 162 open to the second body 120 and a flat depression 163 adjoining the cable duct 162 and open to the second body 120.
[0078] Figures 14-16 show three positions of the translational-rotation fitting 130, mounted on the base plate 140 of the first body 110, during the translational-rotation movement (initial position in Figure 14, intermediate position in Figure 15, and end position in Figure 16). The power cable 101 leading from the power connection element 170 lies partially in the flat recess 163 in all positions of the translational-rotation fitting 130 during the movement of the second fitting plate 132 of the translational-rotation fitting 130.
[0079] This prevents a section of the power cable 101 from being pinched by driving over the second fitting plate 132, which is movable relative to the base plate 140.
[0080] The second fitting plate 132 of the translation-rotation fitting 130 shown here as an example is rotated relative to the first fitting plate 131 and is simultaneously displaceable in the translation direction A via a rail guide 134.
[0081] A curved track 133, which is fastened to a base 121 of the second body 120 by means of the second fitting plate 132, serves to guide the translational and rotational movement of the second body 120 relative to the first body 110.
[0082] By providing the recess 160 in the base or cover plate 140, 150 of the first body 110, it is also possible to route the power cable in the area between the first body 110 and the second body 120, in which the translation-rotation fitting 130 is also arranged.
[0083] In this furniture or household appliance element 100, it is also possible to design the power cable 101, at least in sections, as a spiral cable or as a cable loop.
[0084] A part of the power cable 101 can preferably be wound up with a winding mechanism, which is preferably designed as part of the power connection element 170, as shown by way of example in Figures 11 a and 11 b.
[0085] Figure 11a shows the power connection element 170 with an approximately cylindrical winding body and a cable storage area 172 on the outer surface of the winding body 171 with the power cable 101 largely unwound.
[0086] Figure 11 b shows the power connection element 170 with a section of the power cable 101 wound up in the cable storage area 172. The height of the power connection element 170 is preferably such that, as shown in Figure 10, it has a slightly lower overall height than the overall height of the translation-rotation fitting 130, so that the power connection element 170, fastened to the base 121 of the second body 120, slides over the surface of the base plate 140 without contact during the translation and rotation movement of the second body 120.
[0087] The power connection element 170 may furthermore, as shown in Figure 12, have a central plug connection for receiving a plug 103 passed through an opening in the base 121 of the second body 120.
[0088] The second element of the power cable 108, which is passed through the through-opening 161 of the recess 160 in the base plate 140 of the first body 110, can also be connected directly to a socket on a floor or wall of a room or, as shown in Figure 12, can also be coupled to a plug 102.
[0089] It is also conceivable here to additionally protect sections of the power cable 101 by an energy chain 180.
[0090] Instead of the flat recess 160 provided in the base plate 140, as shown in particular in Figure 9, it is also conceivable to design the recess as a guide groove guiding the power cable 101, as shown in Figures 17a, 17b, 18a, and 18b. Figure 17a shows the position of the translation-rotation fitting 130 corresponding to Figure 14. Figure 17b shows, in a view from below, the position of the power cable 101 projecting downward from the base plate 140 of the first body 110. Figures 18a and b show the position of the translation-rotation fitting 130 corresponding to Figure 16 and, accordingly, the position of the power cable 101 projecting downward from the base plate 140 of the first body 110.
