[0001] The present invention relates to a guide bearing for guiding a body part that is simultaneously mounted to be movable in translation and rotation according to the preamble of claim 1.

[0002] The invention further relates to a furniture element according to the preamble of claim 15.

[0003] A furniture element, for example in the form of shelves or storage units, in which a body part is arranged to be rotatably and translationally movable on or in a support element, is known, for example, from JP H 10318669 A.

[0004] With such furniture elements, there is often a requirement to protect the items stored on them from dirt and to allow good access to the items.

[0005] Particularly with larger and / or taller body parts, it is necessary for stability reasons to adequately support the combined translational-rotational movement by means of a guide bearing, as is known, for example, from DE 10 2019 132 207 A1. Such a guide bearing can be arranged either above and / or below the corresponding body part.

[0006] The object of the present invention is to further develop a guide bearing and a furniture element in such a way that they can be operated without manual force.

[0007] This problem is solved by a guide bearing having the features of claim 1 and by a furniture element having the features of claim 15.

[0008] The guide bearing according to the invention for guiding a body part that is simultaneously mounted to be movable in translation and rotation comprises a first plate with a curved guide track arranged on or in it. A guide element arranged on a second plate is guided in the guide track.

[0009] The guide bearing also features a linear guide with connecting parts that are movable relative to each other, one of which is arranged on one of the plates and the other of which is mounted on the other of the plates by means of a rotary bearing.

[0010] The first or second plate can be attached to the body part or designed as a base plate or top plate of the body part.

[0011] A drive track is arranged along the guide track, to which a drive wheel, located on the second plate and driven by a drive unit, engages.

[0012] Alternatively, the guide element is designed as a drive wheel that can be driven by a drive unit.

[0013] With a guide bearing designed in this way, a guided translational-rotational movement of the body part is easily enabled by actuating the drive unit.

[0014] Advantageous embodiments of the invention are the subject of the dependent claims.

[0015] According to an advantageous embodiment, the drive track is integrated into or formed within the guide track. This allows the guide track to also be used as a drive track.

[0024] According to a further advantageous embodiment, the drive unit has an actuating element for deactivating the drive unit when a predetermined position of the body part is reached.

[0025] The actuating element for deactivating the drive unit can preferably be activated by means of a stop provided on the guide track or the drive track.

[0026] This ensures in a simple way that the drive unit is deactivated in time or when a predetermined position is reached.

[0027] According to an advantageous further development, the actuating element is designed as an actuating lever.

[0028] According to an alternative design, the actuating element is designed as a contactless switching element.

[0029] According to another advantageous embodiment, the drive unit has a control unit for controlling a motor of the drive unit.

[0030] Such a control unit enables a wide variety of operating options for the drive unit.

[0031] The motor of the drive unit is preferably designed as an electric motor.

[0032] According to a preferred embodiment, the control unit preferably includes actuating controls, buttons, or the like. Furthermore, the control unit can be equipped with a wireless interface to enable remote control of the guide bearing.

[0033] The control system can be integrated into a standard smart home system, preferably wirelessly via one of the common frequencies and radio standards (Bluetooth, Zigbee, Wi-Fi, etc.). Voice or gesture control is also conceivable. Furthermore, the storage unit can be controlled via pre-programmed scenarios, for example, depending on the time of day.

[0034] The furniture element according to the invention has a support element with a base support plate and a top support plate.

[0035] The furniture element further comprises a body part which is mounted to be movable both translationally and rotationally relative to the supporting element, with a base plate, a top plate and at least one connecting element connecting the base plate to the top plate.

[0036] A guide bearing is arranged between the top support plate and the top plate and / or between the bottom support plate and the bottom plate.

[0037] The guide bearing has at least one curved guide track and a guide element guided in the guide track, which are arranged on mutually facing surfaces of the top support plate and the top plate and / or the bottom support plate and the bottom plate.

[0038] The guide bearing further comprises a linear guide with connecting parts that are movable relative to each other in a translational direction, one of which is arranged on the top support plate or the top plate and the other is mounted on the other side of the top support plate or the top plate by means of a rotary bearing and / or one connecting part is arranged on the bottom support plate or the bottom plate and the other is mounted on the other side of the bottom support plate or the bottom plate by means of a rotary bearing.

[0039] A drive track is arranged along the guide track, to which a drive wheel, located on the second plate and driven by a drive unit, engages.

[0040] Alternatively, the guide element is designed as a drive wheel that can be driven by a drive unit.

[0041] In a preferred embodiment of the furniture element according to the invention, a translational rotational bearing is positioned between the top support plate and the top plate when the guide bearing is arranged between the top support plate and the bottom plate, and between the top support plate and the top plate when the guide bearing is arranged between the bottom support plate and the bottom plate.

[0043] 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 guide bearing, furniture element, support element, body part, linear guide, and the like as chosen in the respective figures. These terms are not to be understood as restrictive; that is, these relationships may change due to different working positions, mirror-symmetrical design, or similar factors.

[0044] In the Fig. Reference numeral 1 denotes a variant embodiment of a furniture element according to the invention. The furniture element 1 shown here essentially consists of a support element 2 with a base support plate 22 and a top support plate 21, side walls 23 connecting the base support plate 22 to the top support plate 21, and a body part 3 that is movable both translationally and rotationally relative to the support element 2.

[0045] Instead of the side wall 23 connecting the base support plate 22 with the cover support plate 21, a design variant of the support element 2 without side wall 23 is also conceivable, for example when the base support plate 22 and the cover support plate 21 are attached to a building wall.

[0046] The body part 3 also has a base plate 32, a top plate 31 and a connecting element connecting the base plate 32 to the top plate 31, in the illustrated embodiment in the form of at least one side wall 33.

[0047] In the embodiment shown in these figures, the shelf-like body part 3 has a square base, with two side walls 33 that form an interior space in a Fig. Close in the closing position shown in section 1 and close the two open vertical sides, as shown in the diagram. Fig. 2 and Fig. 3, which allow access to the interior.

[0048] Instead of side walls, it is also conceivable to connect the base plate 32 with the cover plate 31 via corner posts or a central post in the center of the surface of the base plate 32 or cover plate 31.

[0049] In the version shown here, the interior of the cabinet section 3 has several shelves 34. However, other configurations or subdivisions of the interior of the cabinet section 3 are also conceivable in principle.

[0050] On the base support plate 22 of the support element 2, as shown in the Fig. 3 and Fig. 4 shown, support feet 24 arranged.

[0051] What next in the Fig. 2 - 4 is shown, between the cover support plate 21 and the cover plate 31, shown in the Fig. 2 and Fig. 3, and / or between the base support plate 22 and the base plate 32, shown in Fig. 4, a guide bearing 4 arranged, with which the simultaneous translational and rotational movement of the body part 3 relative to the support element 2 is enabled.

[0052] Preferred embodiments of such a guide bearing 4 are described in the Fig. 5 - 16 are shown in more detail.

[0053] The guide bearing 4 has at least one curved guide track 5 and a guide element 10 guided in the guide track 5. The guide track 5 and the guide element 10 are arranged on mutually facing surfaces of the top support plate 21 and the top plate 31 or the bottom support plate 22 and the bottom plate 32.

[0054] The guide bearing 4 further comprises a linear guide 7, with connecting parts that are movable relative to each other in a translational direction A, one of which is arranged on the top support plate 21 or the top plate 31 and the other is mounted on the other of the top support plate 21 or the top plate 31 by means of a rotary bearing 6.

[0055] When the guide bearing 4 is arranged between the base plate 32 and the base support plate 22, one connecting part is arranged on the base support plate 22 or the base plate 32 and the other is supported on the other of the base support plate 22 or the base plate 32 by means of a rotary bearing 7.

[0056] In the embodiment shown here, such a guide bearing 4 is arranged both between the top support plate 21 and the top plate 31 and between the bottom support plate 22 and the bottom plate 32.

[0057] It is also conceivable to equip the furniture element 1 with only one guide bearing 4 and, if the guide bearing 4 is arranged between the top support plate 21 and the top plate 31, to position a translational rotational bearing between the bottom support plate 22 and the bottom plate 32, and correspondingly, if the guide bearing 4 is arranged between the bottom support plate 22 and the bottom plate 32, to position the translational rotational bearing between the top support plate 21 and the top plate 31.

[0058] For example, a translational rotary bearing such as that known from DE 10 2019 109 866 A1 can be used.

[0059] Along guideway 5, during the Fig. In the embodiment shown in Figures 5 to 12, a drive track 52 is arranged on which at least one drive wheel 91, which can be driven by a drive unit 9, engages, as exemplified in Figures 5 to 12. Fig. 6 is shown.

[0060] It is also conceivable that the guide element 10 itself is designed as a drive wheel that can be driven by a drive unit 9.

[0061] In principle, it is also conceivable to design such a guide bearing 4 for guiding a movable body part 3 in such a way that the curved guide track 5 is arranged on or in a first plate of the guide bearing 4 and the guide element 10 is arranged on a second plate of the guide bearing 4.

[0062] Accordingly, the guide bearing 4 has a linear guide 7 with connecting parts that are movable relative to each other, one of which is arranged on one of the plates and the other of which is mounted on the other of the plates by means of a rotary bearing 6.

[0063] In the illustrated embodiment, the guide track 5 is fixed on the cover plate 31 of the body part 3 in the guide bearing 4 arranged between the cover support plate 21 of the support element 2 and the cover plate 31 of the body part 3.

[0064] The guide element 10 is, as in the Fig. 6 and Fig. 7 in conjunction with the Fig. 2 and Fig. 3 can be seen, on a carrier plate 8 in a guide element receptacle 81, wherein the carrier plate 8 itself is fixedly attached to the cover carrier plate 21 of the carrier element 2.

[0065] The carrier plate 8 also serves to fix a drive housing 92 of the drive unit 9 with the drive wheel 91 protruding from it, as well as to fix a guide rail 71 of the linear guide 7 to a guide rail receptacle 82.

[0066] The linear guide 7 consists, as in the Fig. 6, Fig. 8 and Fig. Figure 9 shows two guide rails 71 which are attached to a support plate 8, and two running rails 72 which are linearly displaceable in the guide rails 71 and which are attached to the cover plate 31 of the body part 3 via a pivot bearing 6.

[0067] The longitudinal extent of the guide rails 71 and running rails 72 determines the translation direction A of the combined translation-rotation movement of the body part 3 relative to the support element 2.

[0068] The rotary bearing 6 preferably consists of a mounting plate 61, which is attached to the cover plate 31 of the body part 3, a coupling piece 62, to which the two guide rails 72 are fixed, and a rotary table 63, which is received in a cylindrical recess provided for this purpose in the coupling piece 62.

[0069] The turntable 63 is rotatable about a rotation axis 65 and is mounted on the mounting plate 61 via a radial support 64.

[0070] The drive wheel 91 of the drive unit 9 is positioned such that it is always in contact with the drive track 52 during the translational-rotational movement of the body part 3 relative to the support element 2. In the embodiments shown here, the drive track 52 is designed as a side surface of the guide track 5.

[0071] The rotary movement of the drive wheel 91 moves the drive track 52 and with it the body part 3, on whose top plate 31 or bottom plate 21 the guide track 5 is moved translationally and rotationally in the path determined by the geometric design of the guide track 5.

[0072] It is also conceivable to design such a drive track 52 as a separate component and, for example, to arrange it parallel to the guide track 5.

[0073] The drive wheel 91 is located in the Fig. 6 - 12 shown design variant as friction wheel and the drive track 52 accordingly designed as friction track.

[0074] It is also conceivable, as in the Fig. 13 and Fig. 14 shows the drive wheel 91 as a gear and the drive track 52 as a rack railway.

[0075] It is also conceivable, as in the Fig. 15 and Fig. As shown in Figure 16, the drive track 11 is to be designed separately from the guide track 5 as a separate track body.

[0076] In the embodiment shown here, the drive track 11 has a contact surface 12, preferably designed as a friction track, against which the drive wheel 91, designed here as a friction wheel, rests. The drive track 11 is preferably attached to the first plate by means of mounting lugs 13 molded onto it.

[0077] As in Fig. As shown in Figure 10, the drive wheel 91 is biased in the direction of the drive track 52 by means of a spring element 95.

[0078] At the in Fig. In the embodiment shown in Figure 10, the spring element 95 is clamped between the housing 94 of the drive unit 9 and a spring stop 84 molded onto the carrier plate 8.

[0079] What next in the Fig. 10 and Fig. As can be clearly seen in Figure 12, the drive unit 9 also has an actuating element 92 for deactivating the drive unit 9, which can be activated by a stop 53 provided in the illustrated embodiment in the area of ​​the ends of the guide track 5 or the drive track 52.

[0080] If the body part 3 is to be stopped in predetermined intermediate positions, for example when reaching an angle of 45° or 135° relative to the starting position of the body part 3, it is conceivable to provide additional stops 53 at corresponding positions of the guide track 5 or the drive track 52.

[0081] In the preferred embodiment shown here, the actuating element 92 is designed as an actuating lever. The actuating lever is preferably coupled to a control unit (not shown) of the drive unit 9 for controlling a motor of the drive unit 9, which is preferably designed as an electric motor.

[0082] The actuating element 92 can thus be pivoted from a motor operating position to a switch-off position by striking the stop 53 when the stop 53 is reached.

[0083] Instead of the actuating element 92 designed as an actuating lever, it is also conceivable to control the control part of the drive unit 9 at a predetermined position of the body part 3, for example by means of magnets and Hall sensors or reed switches arranged on the drive track or the drive wheel.

[0084] The use of other mechanical contact switches is also conceivable. For example, upon reaching a predetermined position, the actuation of an activator, such as a switching cam on the drive track, can actuate a switch coupled to the control unit of the drive unit 9.

[0085] The control unit of the drive unit 9, not shown here, is preferably equipped with actuators, buttons, or the like for controlling the electric motor. It is also conceivable to equip the control unit with a wireless interface so that it can be addressed via Bluetooth, Wi-Fi, voice control, or other communication methods, for example, to be integrated into a smart home system.

[0086] In this embodiment, the drive unit 9 is supplied with power via a cable 93. Power supply via a storage device or batteries would also be conceivable.

[0087] It is also conceivable to design the control unit in such a way that it is controlled via routines. For example, the position of the body part 3 relative to the support element 2 can be set in different scenarios, for example depending on the time of day.
