Description

Technical Field

[0001] The present invention relates to furniture or household appliances of a modular interior design system for rooms according to the preamble of claim 1, or a translational rotary device for a group of furniture or household appliances, and furniture or household appliances according to the preamble of claim 3.

Background Art

[0002] Common furniture or household appliances, or translational rotary devices for furniture or household appliances, simplify access to difficult-to-reach areas within the storage space of furniture or household appliances, or enable variable arrangements of furniture or household appliances within a group of furniture or household appliances of a modular interior design system for rooms, or enable variable positioning of the entire group within a room.

[0003] Simultaneous translational and rotational movements of furniture or household appliances, or such translational rotary devices, are achieved by arranging a translational rotary fitting between a first body of the furniture and a second body that is moved relative to the first body. Alternatively, the relative movement can also be performed between a movable body of the furniture and the ceiling and / or floor of the room.

[0004] In a translational rotary device, the translational rotary movement is achieved by, for example, guide cam tracks within a bearing area of a base and a support element arranged thereon, with the group of furniture and / or household appliances positioned on the support element. Such common translational rotary devices are known, for example, from International Patent Publication No. 2021 / 001395 or International Patent Publication No. 2020 / 212373.

[0005] A problem regarding such components that can move relative to each other is the supply of electrical energy to support elements that perform translational and rotational movements or electrical devices housed within the second body.

Summary of the Invention

Problems to be Solved by the Invention

[0006] An object of the present invention is to further develop a translational rotation device for furniture or household appliances, or groups of furniture and / or household appliances, for modular interior design systems for rooms, so that they can be equipped with a power source in a simple manner at a support element or second body that moves in translation and rotation. [Means for solving the problem]

[0007] This objective is achieved by a translational rotating device for furniture, household appliances, or groups of furniture and / or household appliances in a modular interior design system for rooms having the features of claim 1, and by components of furniture or household appliances having the features of claim 3.

[0008] A translational rotating device according to the present invention for furniture, household appliances, or groups of furniture and / or household appliances in a modular interior design system for a room has a base and support elements having flat bearing areas facing each other. The support element is mounted so that it can be translated and rotated at least partially relative to the base.

[0009] A guide cam track is positioned on one side of the bearing region, and a guide element guided within or on the contour of the guide cam track is positioned on the other side of the bearing region, thereby enabling the support element to be guided at least partially and reliably relative to the base, to rotate in one of two possible opposite directions of rotation and to move in a predetermined translational direction.

[0010] The guide cam trajectory is shaped so that when torque is applied to the support element, the support element moves from an initial position through an intermediate position, where it moves to an end position that coincides with the initial position by rotating relative to the base in one of two possible opposite directions of rotation, displacing in the translational direction, and further rotating in the other of the two possible opposite directions of rotation, displacing in the opposite direction of translation.

[0011] The base has guide grooves that extend in the translational direction. Guide elements protruding into the guide grooves are positioned on the bearing area of ​​the support element. Alternatively, the guide grooves may be positioned on the bearing area of ​​the support element and on the guide elements within the base. The guide element is configured as a rotation feedthrough.

[0012] The first power connection element is mounted on the side of the base opposite to the bearing area of ​​the base, and the second power connection element is mounted on the side of the support element opposite to the bearing area of ​​the support element.

[0013] Both power connection elements are connected to each other via power cables supplied through a rotary feedthrough. The furniture or household appliance according to the present invention has a first body and a second body that is movable relative to the first body. Furthermore, the furniture or household appliance may have a translational-rotating fitting that can be used to move the second body relative to the first body in a predetermined translational direction and at least partially simultaneously in one of two possible opposite rotational directions.

[0014] The translational-rotational fitting device comprises a first fitting plate coupled to a first body and a second fitting plate coupled to a second body, wherein the second fitting plate can be translated and rotated at least partially simultaneously with respect to the first fitting plate.

[0015] In the closed position of the second body, a recess is provided in the base or cover plate of the first body in the overlapping area between the base or cover plate of the first body and the second body. A power cable is passed through this recess, and at its first end, the power cable is connected to a power connection element mounted on the side of the second body facing the base or cover plate of the first body. The recess may also take the form of a hole.

[0016] In both translational and rotational devices and furniture or household appliances, the above-described device ensures a simple power supply to an electrical load located or installed in a second body that is movable in translation and rotation, or on or within a support element.

[0017] In addition to a conventional first body used as a support having a base plate, a cover plate, and at least one side wall, a second body, at least partially mounted for simultaneous translational and rotational movement, is fixed directly to the room wall only via the base plate and cover plate that form the first body. Advantageous embodiments of the present invention are the subject matter of the dependent claims.

[0018] According to one advantageous embodiment of the configuration of the present invention, the first power connection element is mounted on a base on the side of the guide groove and offset approximately parallel to the center when viewed from the longitudinal direction of the guide groove. This arrangement of the first power connection element reduces the variation in the distance between the first power connection element and the translationally moving guide sleeve.

[0019] According to an advantageous embodiment of the furniture or household appliance of the present invention, the recess has a through opening, a groove-shaped cable duct opening toward the second body, and a flat recess adjacent to the cable duct and opening toward the second body.

[0020] According to an alternative embodiment of furniture or household appliances according to the present invention, the recess is configured as a guide groove for guiding a power cable. According to a further alternative embodiment of the furniture or household appliance according to the invention, the recess is configured as a hole. All variants ensure that the power cable can move together with the translational and rotational movement of the second body without getting stuck in the area of the recess.

[0021] According to a further advantageous embodiment of the device or furniture or household appliance, it has a winding mechanism with a cable storage area, and during the translational and rotational movement of the second body or the support element, a part of the power cable is wound up or unwound on the cable storage area.

[0022] Also, such a winding mechanism prevents the power cable from getting stuck or entangled during the movement of the second body or the support element. According to an alternative embodiment, the power cable is at least partially configured as a spiral cable or a cable loop, thus enabling, in particular, the linear extension of the power cable required by the translational movement.

[0023] According to a variant of a further advantageous configuration, the power cable is at least partially guided within an energy chain. This further prevents the power cable from being pinched or suffering similar damage during the movement of components that are movable relative to each other.

[0025] In the following description of the figures, terms such as top, bottom, left, right, front, and back refer exclusively to exemplary representations and positions of furniture or household appliances, translational-rotational fittings, bases, support elements, first body, second body, etc., selected in each figure. These terms should not be understood restrictively; that is, their references may vary depending on different working positions or mirror-symmetric configurations.

[0026] Hereinafter, embodiments of the translational rotation device according to the present invention for furniture, household appliances, or groups of furniture and / or household appliances in a modular interior design system for a room will be described with reference to Figures 1 to 8. Further Figures 9 to 18 are helpful in illustrating further embodiments of the furniture or household appliance 100 according to the present invention.

[0027] One such group 11 of furniture or household appliances for a modular interior design system for a room is shown as an example in Figure 8. As can be seen here, the entire group 11 of furniture and / or household appliances is placed on a support element 3 mounted on a base 2.

[0028] As an example of furniture group 11, Figure 8 shows a shelf 12, a chair 13, and a table 14 placed on a support element 3, which allows the furniture group 11 to be positioned in the room by the translational rotational motion of the support element 3 relative to the base 2, allowing it to be rotated by, for example, an angle of 90°.

[0029] As shown in Figures 1 to 7, the base 2 and the support element 3 have opposing flat bearing regions 21 and 31. As described above, the support element 3 is mounted on the base 2 so that it can perform translational and rotational motion simultaneously.

[0030] For this purpose, the guide cam track 22 is located in one of the bearing areas 21, 31 of the base 2 or the support element 3, and the guide element 4, which is guided within or along the contour of the guide cam track 22, is located in the other bearing area 21, 31.

[0031] As a result, the support element 3 can be actively guided at least partially relative to the base 2, rotated in one of two possible opposite rotational directions R1, R2, and moved in a predetermined translational direction A.

[0032] Movement in the translational direction A is further guided by a guide groove 23 extending along the translational direction A within the base 2 and a guide element protruding into the guide groove 23 in the bearing area 31 of the support element 3. The guide element is configured as a rotational feedthrough 5.

[0033] Furthermore, the guide cam trajectory 22 is formed such that when torque is applied to the support element 3, the support element 3 is rotated from its initial position, through an intermediate position where it is rotated in one of two possible opposite rotational directions R1, R2 relative to the base 2 and displaced in the translational direction A, and then further rotated in one of two possible opposite rotational directions R1, R2 and displaced in the opposite direction of translation A, to a terminal position that coincides with the initial position.

[0034] To enable power supply to furniture and / or household appliances placed on the support element 3, or to electrical consumers placed on or within them, a first power connection element 6 is attached to the base 2 on the side opposite to the support element 3, and a second power connection element 7 is attached to the upper side of the support element 3 on the side opposite to the base 2.

[0035] The two power connection elements 6 and 7 are connected to each other via a power cable 8 that passes through the rotating feedthrough 5. The power cable 8 is guided through a preferably cylindrical through-opening 51 of the rotating feedthrough 5, which forms a passage for the power cable from the side of the base 2 opposite the support element 3 to the upper side of the support element 3 opposite the base 2.

[0036] As further shown in Figures 2 to 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 configured, for example, as a socket on the wall or floor of the room.

[0037] Figures 3 to 7 show the translational and rotational motion of the support element 3 relative to the base 2, and the furniture group 11 is positioned 90° offset from the base 2, as shown in Figure 8 as an example.

[0038] By passing the power cable 8 through the through-opening 51 of the rotational feedthrough 5, it is possible to lay a cable that reliably connects power connection elements 6 and 7, one of which is located on the base 2 and the other on the support element 3, even during the translational rotational motion of the support element 3 relative to the base 2. The power cable 8 is preferably configured as a spiral cable.

[0039] Alternatively, the power cable 8 could be dragged along with the translational and rotational motion of the support element 3 relative to the base 2. As illustrated by the different positioning of the support element 3 relative to the base 2 in Figures 3 to 7, the appropriate placement of the first power connection element 6 attached to the base 2 on the side of the guide groove 23, and the appropriate placement of the first power connection element 6 offset parallel to the center of the longitudinal direction of the guide groove 23, ensure that the length of the power cable 8 required to bridge the distance between the first power connection element 6 and the rotary feedthrough 5 changes only slightly.

[0040] The distance between the rotating feedthrough 5 and the second power connection element 7 is in any case determined by the distance between the second power connection element 7 and the rotating feedthrough 5, which is also fixed to the support element 3. Guiding the support element 3 on the base 2 via the guide cam track 22 and via the guide element 4 guided along or within the guide cam track 22 is not obstructed by the power cable 8, as the power cable 8 is guided through the through-opening 51 of the rotation feedthrough 5. Figures 9 to 16 show embodiments of furniture or household appliances 100 according to the present invention.

[0041] The furniture or household appliance 100 has a first body 110 and a second body 120 that is movable relative to the first body 110. As shown in Figure 10, the second body 120 is exemplary configured here as a shelf having an intermediate shelf with two sides closed by side walls, and the second body 120 is attached adjacent to the fixed first body 110 by a translational-rotary fitting 130 so as to be movable relative to the first body 110 in translational and rotational directions. In the illustrated embodiment, the cover plate 150 is located above the first body 110 and also covers the second body 120, and a translational rotation fitting device 130 for moving the second body 120 is also arranged on top of it.

[0042] The translational-rotational fitting 130 enables simultaneous relative motion of the first body 110 in a predetermined translational direction A and one of two possible opposite rotational directions R1 and R2. The translational-rotating fitting device 130 includes a first fitting plate 131 connected to a first body 110 and a second fitting plate 132 connected to a second body 120, and the second fitting plate 132 is capable of simultaneous translational and rotational movement relative to the first fitting plate 131.

[0043] Here, recesses 160 are provided in the base or cover plates 140 and 150 of the first body 110, and in the closed position of the second body 120, power is supplied to a power consumer located on or inside the second body 120 in the overlapping region of the base or cover plates 140 and 150, in this case the overlapping region of the base plate 140 of the first body 110 and the second body 120.

[0044] In the illustrated embodiment, the recess 160 is provided in the base plate 140 of the first body 110. The power cable 101 is passed through this recess 160, and at the first end of the power cable 101 is connected to a power connection element 170, which is fastened to the side of the second body 120 facing the base plate or cover plates 140, 150 of the first body 110.

[0045] The recess 160 provided within the base plate 140 has, in particular as shown in Figure 9, a through opening 161, a groove-shaped cable duct 162 opening to the second body 120, and a flat recess 163 adjacent to the cable duct 162 and opening to the second body 120. Figures 14 to 16 show three positions of the translational rotation fitting 130 mounted on the base plate 140 of the first body 110 during translational rotational motion (initial position in Figure 14, intermediate position in Figure 15, and final position in Figure 16).

[0046] While the second mating plate 132 of the translational-rotating mating device 130 moves through all positions of the translational-rotating mating device 130, the power cable 101 extending from the power connection element 170 is partially positioned within the flat recess 163. This prevents a portion of the power cable 101 from being caught by passing over the second mating plate 132, which moves relative to the base plate 140.

[0047] In the translational-rotating fitting device 130 shown here as an example, the second fitting plate 132 can rotate relative to the first fitting plate 131 while simultaneously being displaceable in the translational direction A via the rail guide 134. Here, the cam track 133, which is attached to the base 121 of the second body 120 by the second fitting plate 132, guides the translational and rotational movements of the second body 120 relative to the first body 110.

[0048] In this way, by providing recesses 160 within the base or cover plates 140 and 150 of the first main body 110, it becomes possible to route the power cable in the area between the first main body 110 and the second main body 120, where the translational rotation fitting device 130 is also located. With respect to this furniture or household appliance 100, the power cable 101 may also be formed at least partially as a spiral cable or as a cable loop.

[0049] Preferably, a portion of the power cable 101 can be wound using a winding mechanism, and this winding mechanism is preferably formed as part of the power connection element 170, as illustrated in Figures 11a and 11b. Figure 11a shows a power connection element 170 comprising a nearly cylindrical winding body and a cable storage area 172 on the outer sheath surface of the winding body 171 when most of the power cable 101 is unwound. Figure 11b shows a power connection element 170 in which a portion of the power cable 101 is wound into the cable storage area 172.

[0050] The height of the power connection element 170 is preferably slightly lower than the overall height of the translational-rotational fitting 130, as shown in Figure 10, so that the power connection element 170, fixed to the base 121 of the second body 120, slides on the surface of the base plate 140 without contact during the translational and rotational motion of the second body 120.

[0051] The power connection element 170 may further include a central plug connector for receiving a plug 103 that passes through an opening in the base 121 of the second body 120, as shown in Figure 12. The second element of the power cable 108 is passed through the through-opening 161 of the recess 160 in the base plate 140 of the first body 110, but it can also be connected directly to a socket on the floor or wall of the room, or it can be coupled to a plug 102 as shown in Figure 12. Furthermore, it is also conceivable to further protect a portion of the power cable 101 with the energy chain 180.

[0052] Furthermore, as shown in Figure 9 in particular, instead of the flat recess 160 provided in the base plate 140, it is also conceivable to form a recess as a guide groove for guiding the power cable 101, as shown in Figures 17a, 17b, 18a, and 18b. Figure 17a shows the position of the translational-rotating fitting 130 corresponding to Figure 14, and Figure 17b shows the position of the power cable 101 protruding downward from the base plate 140 of the first body 110, viewed from below. On the other hand, Figures 18a and 18b show the position of the translational-rotating fitting 130 corresponding to Figure 16, and accordingly, the power cable 101 protrudes downward from the base plate 140 of the first body 110.
