Description

[0001] Rotating device and turntable arrangement

[0002] The present invention relates to a rotating device for integration into a subsurface, preferably into a building floor element, in particular a screed floor, having the features of patent claim 1 and to a rotating plate arrangement with such a rotating device having the features of patent claim 24.

[0003] Rotating devices are already known in various designs from the prior art. Rotating devices are known, for example, as turntables, turntables, and for various other uses. For example, turntables are a popular attraction in playgrounds, such as a rotating disc or a carousel.

[0004] Rotating devices with larger diameters and higher static loads often have a large design and are often complex, heavy and associated with considerable costs.

[0005] For example, WO 98 30424 A shows a turntable device for absorbing high static loads. A base plate and a turntable which can rotate relative to the base plate are provided, the turntable being mounted on the base plate via support bearings arranged on the outer circumference and the base plate being supported on the ground. The turntable is arranged at a distance from the ground, as a result of which the turntable device has a relatively large overall height and a step at the edge of the turntable must be overcome in order to access the turntable. Such steps represent hazards, particularly when such turntable devices are integrated into buildings.

[0006] This is where the present invention comes in.

[0007] Based on this prior art, the object of the present invention is to propose a suitably improved turntable device that eliminates the disadvantages known from the prior art. The proposed turntable device should be capable of being retrofitted into existing buildings and integrated as flush as possible into a building floor element, thereby creating adaptable spaces.

[0008] These objects are achieved by a rotary plate device for integration into a subsurface, preferably into a building floor element, in particular into a screed floor, having the features of patent claim 1 and a rotary plate arrangement having the features of patent claim 24.

[0009] Further advantageous developments of the invention are specified in the subclaims.

[0010] The rotating plate device according to the invention for integration into a substructure, preferably into a building floor element, in particular into a screed floor, with the features of patent claim 1 has at least three support units which are arranged circumferentially within a circular area around a rotation axis and can be individually inserted into a recess in the substructure. In addition, the rotating device has a rotating plate which extends at least over the circular area and has a room side and a bearing side opposite the room side.Furthermore, a rotary bearing unit and at least one drive device are provided, wherein the rotary plate is rotatably mounted in the rotation axis by the rotary bearing unit and the at least three support units, individually supported by the rotary bearing unit, rotatably support the rotary plate in the orientation of the rotation axis in a vertical axis on the bearing side and wherein the drive device is designed to set the rotary plate in a rotation about the rotation axis.

[0011] The at least three support units and the pivot bearing unit according to the present invention are not directly connected to one another. The at least three support units and the pivot bearing unit can be individually and independently inserted into recesses in the subfloor, in particular a floating standard screed floor, and arranged there in a recess. The at least three support units and the pivot bearing unit are thus indirectly connected to one another through the subfloor, as a result of which, for example, an existing building floor, in particular a screed floor, can be used as a load-bearing structure and a system which is highly flexible in size and load-bearing capacity is created using simple means and which can also be easily retrofitted in existing buildings thanks to its low installation height. The proposed rotating device is therefore resource-saving, flexible, efficient and can be used across a wide range of applications.Because the at least three support units and the pivot bearing unit are integrated into the substructure, particularly into the floor element, and even more preferably into the screed floor, all load-related and natural settlement phenomena can be flexibly compensated for. Furthermore, the building's physical properties in terms of thermal and sound insulation are only changed very slightly, which is why the proposed pivoting device is suitable for residential buildings.

[0012] , sleeping and working spaces.

[0013] The rotating device is therefore suitable for retrofitting, as well as planned new construction and corresponding combinations thereof. One of the key advantages over the known state of the art is that only small, localized interventions in the subfloor, in particular the screed, are required, meaning that the subfloor, in particular the screed, loses little or no load-bearing capacity and may even break. Furthermore, the subfloor in the area of ​​the rotating device can be consolidated if necessary with a fabric that is preferably applied with filler. The fabric can also consolidate the subfloor over the circular area, preferably over a large area.

[0014] The rotating device adapts to completely different settlement and expansion behaviors. This makes it possible to control the height of the subfloor, especially the finished floors, relative to the room side of the rotating plate, thus meeting today's qualitative and aesthetic architectural requirements.

[0015] A further advantage is that the proposed individual and easy-to-use rotating device also gives rise to new, very compact and attractive living and workplace concepts. More individual options can therefore be created with less space. The rotating device can also function as a replacement for very large doors, offering expanded usage options. Furthermore, the rotating device can also be used in storage spaces and / or access points such as doors, although the applications listed are not limited to the examples mentioned above. A further development of the present invention provides that the at least one drive device is arranged on and / or below the rotating plate. The at least one drive device therefore rotates together with the rotating plate about the axis of rotation during rotation of the rotating plate.

[0016] According to a preferred embodiment of the present invention, the at least one drive device is arranged substantially on the room side of the rotating plate. While this accepts that the drive device is (at least predominantly) arranged on the room side of the rotating plate, the room side of the rotating plate can thereby be arranged approximately flush with the ground.

[0017] In an alternative embodiment, the at least one drive device can be arranged substantially on the bearing side, allowing the room side of the rotating device to be barrier-free. Such a rotating device can serve, for example, as a dance, show, or presentation floor.

[0018] Furthermore, it is possible for the drive device to be permanently connected to the base and drive the turntable. Combinations of the previously described drives are also possible.

[0019] Particularly in the case of very large turntables, a combination of at least one drive device on the turntable and at least one drive device on the base can be advantageous. The drive device, which is fixedly arranged on the base beneath the platform, does not rotate, unlike the at least one drive unit on the turntable. Nevertheless, the two drive devices complement each other through appropriate synchronization. For the at least one drive device operating beneath the platform, a friction surface or a friction lining must then be provided in addition to the frame structure or the like on the bearing side of the turntable. This drive device can also interact with the bearing surface on the frame structure.

[0020] Such a combination, or an exclusive arrangement of the drive devices on the subfloor, can be particularly advantageous if the drive devices on the upper side are disruptive, for example, if a wooden beam ceiling, or even a solid or concrete ceiling, is combined with a floating screed. In this case, drive devices could be provided on the bearing side of the turntable or on the subfloor, which is straightforward in most cases.

[0021] Preferably, the at least one drive device can be arranged concealed in a piece of furniture, such as a chest of drawers, a cupboard, a couch, a bed, or the like, whereby the appearance of the room is not disrupted by the drive device protruding from the side of the room. Alternatively, the at least one drive device can also be arranged concealed in a room partition element, such as a wall, a wall sign, or the like.

[0022] A preferred development of the present invention provides that the at least one drive device comprises a friction wheel. The friction wheel is driven by the drive device and, according to a preferred embodiment, can roll on a friction surface, in particular the ground. Furthermore, the friction wheel can be designed as a tire and / or, in a conceivable embodiment, have a tread made of a plastic or rubber. This can reduce running noise of the friction wheel and, moreover, even with slight unevenness of the ground, sufficient

[0023] Adhesion of the friction wheel to the surface must be ensured.

[0024] According to a further embodiment of the present invention, the friction wheel extends through the rotating plate through a friction wheel recess. Preferably, the friction surface and the friction wheel, or its bearing and / or drive, are arranged on opposite sides of the rotating plate. The friction wheel can thus have a very large diameter compared to the thickness of the rotating plate, which, on the one hand, allows for a simple design of the rotating device, and, on the other hand, allows the friction wheel of the at least one drive device to apply a sufficiently large force to cause the rotating plate to rotate about the rotation axis.

[0025] According to a preferred embodiment of the present invention, the drive device can be detachably attached as a unit on the spatial side of the rotary plate. Furthermore, the drive device can comprise a frame, wherein the frame comprises a decoupling device that preferably mechanically decouples the friction wheel and / or the drive from the rotary plate in terms of vibration. This suppresses the transmission of running noise from the friction wheel to the rotary plate, and a corresponding design of the decoupling device can ensure that the friction wheel is pressed against the friction surface with a predefined contact pressure.

[0026] Furthermore, it has proven advantageous to provide a slip ring unit and a brush unit that interacts with the slip ring unit. The slip ring unit and the brush unit enable the rotary plate to be supplied with electrical current. The slip ring unit and the brush unit preferably transmit mains current, for example, approximately 230 V at 50 Hz, allowing conventional electrical devices on the rotary plate, such as lights, media devices, or the like, to be operated there. In addition, the power supply can supply the drive device with the necessary energy.

[0027] The rotary bearing unit preferably comprises the slip ring unit. The brush unit can be detachably attached to the rotary plate, allowing the brush unit to be replaced without significant effort.

[0028] The pivot bearing unit preferably further comprises a base part and a pivot plate part. The pivot plate part is rotatably supported on the base part via a bearing, wherein even more preferably the pivot plate part is displaceable relative to the base part along the axis of rotation. The special feature of the pivot bearing unit is that the base part, when it is fixed to the soffit, has an important special feature. In this case the axis of rotation Z is firmly fixed to the subfloor or building and the structure of the pivot plate can compensate for the special feature of a floating screed, which naturally rests on insulation and a vapor barrier. In concrete terms, this means that if the screed settles and deforms slightly over the years as a result of its own weight and corresponding uneven loads through use, these changes can be compensated automatically.This can result in the rotational axis of the rotating device having to compensate for the changed geometry due to settlement and warping in a stress-free manner with the rotational axis Z of the fixed component. This can then also result in slight wobbling. This is also and particularly true because, according to a preferred embodiment, the rotating plate is designed such that, as a flexible membrane with load distribution via the support units, it can completely compensate for these geometric changes via connecting pieces, which in this case can be made of a special pressure-resistant sliding material made of plastic.

[0029] In special cases, particularly when several rotating devices are mounted on a substrate, especially screed, it can also be advantageous from a structural physics perspective if the pivot bearing unit is also glued into the floating part of the substrate, especially the screed. This is advantageous in order to avoid tensions between the axis of rotation and a construction joint between the respective rotating plates at the transition to the floor covering fixed to the substrate. In this case, there is no form-fitting and / or force-fitting connection to the fixed building structure, but only to the floating part of the substrate itself.

[0030] One of the advantages of the rotating device is evident in the area of ​​the joints between the subfloor and the rotating plate. This joint can be kept relatively small and is very tolerant of possible height offsets and expansion coefficients because the rotating plate is a relatively soft membrane that rests on a varying number of support units depending on the intended load from use. This area therefore offers many advantages, both technically for barrier-free transitions and visually from a quality and facility-specific perspective. A development of the present invention provides for the provision of a control unit. The control unit is configured in particular to implement corresponding control commands with the drive device or to control the drive device.The control unit can also preferably be remotely controlled, whereby the control unit can receive control commands either via radio or via a cable via the slip ring unit and the brush unit interacting with the slip ring unit. The control commands can either be transmitted to the control unit via at least one separate conductor or can be modulated onto the current-carrying conductor(s), for example in the form of an ASi bus system.

[0031] According to a preferred embodiment of the present invention, the drive device comprises an electric drive for generating the rotation of the rotating plate about the rotation axis. The drive device can drive the rotating plate using a variety of known drive types. Examples include gears, chain and belt drives, and linear motors (LIM / LSM), although this list is not exhaustive.

[0032] At this point it should be noted that it is also conceivable to drive the drive device hydraulically or pneumatically .

[0033] Furthermore, a further development of the present invention provides that at least one of the at least three support units comprises a rolling bearing element supported on the housing. The rolling bearing element comprises a rolling body movably arranged on the housing, which preferably protrudes from the housing and by means of which the rotating plate is held supported on the housing. During rotation of the rotating plate, the rolling body rolls on the rotating plate.

[0034] The rolling element can, for example, comprise a roller or a ball, wherein the rolling element can furthermore have a rolling element surface made of metal, rubber or plastic, by means of which the rolling element can roll particularly quietly on the rotating plate.

[0035] To further optimize the rolling behavior of the rolling elements, the rotational axis of each rolling element can be tilted so that the respective outer diameter of the inner and outer roller surfaces corresponds to the rotational axis of the respective rolling element at exactly the same speed of the inner and outer orbits of the respective rolling element. This allows greater loads to be transferred to the rolling elements and improves the rolling behavior to such an extent that unpleasant squeaking and / or friction noises are avoided. Furthermore, it can be advantageous if the rollers, particularly those close to the rotational axis, are crowned to prevent any running noise.

[0036] Furthermore, a development of the present invention provides that at least one of the at least three support units comprises an air bearing means or gas bearing means. The air bearing means or gas bearing means preferably comprises a housing and is further preferably designed to keep the rotary plate separated from the at least one of the at least three support units by a thin gas or air film. Due to the stick-slip-free and friction-free movement between the at least one of the at least three support units and the bearing side of the rotary plate, the rotary plate can be moved particularly smoothly. For example, such a rotary plate can be moved by hand and / or the power of the drive device can be reduced. Noise during rotation of the rotary plate can also be reduced in this way.

[0037] Furthermore, it has proven advantageous if a support surface is provided on the housing. In a preferred embodiment, the housing can be sleeve-shaped, and the support surface can protrude from the housing in a flange-like manner. The housing is supported on the substrate via the support surface. Furthermore, the housing can have one or more transverse and / or longitudinal grooves on its outer surface, whereby the support unit can be inserted like a dowel into the respective recess in the substrate.

[0038] Furthermore, it has proven advantageous if the support unit has fastening means by which the support unit can be attached to the substrate. For example, one or more clamping screws or clamping claws can be provided.

[0039] According to a preferred development of the present invention, adjustment means are provided by means of which the rolling bearing element can be adjusted in the vertical axis of the support unit. In particular, it is preferred if the rolling bearing element can be adjusted in the vertical axis relative to the housing of the support unit by means of the adjustment means. The adjustment means make it possible to compensate for any unevenness in the surface in order to ensure uniform support of the rotary plate over the circumference and very smooth running. The adjustment means can additionally comprise a sleeve which is movable in the vertical axis relative to the housing and which can be fixed in position relative to the housing by appropriate fixing means. For example, the sleeve can be a screw sleeve which can be screwed into the housing, wherein the fixing means can prevent the sleeve from rotating relative to the housing.

[0040] Furthermore, it has proven advantageous if the rotating plate has at least one preferably annular bearing surface on the bearing side. The at least one preferably annular bearing surface can be arranged concentrically to the axis of rotation.

[0041] Preferably, the rotating plate has a plurality of coaxially arranged bearing surfaces on the bearing side around the rotation axis, whereby a plurality of support units can be arranged both in the circumferential direction and at different radii with respect to the rotation axis. The weight of the rotating plate and the objects arranged on the rotating plate can be transferred to the ground in an evenly distributed manner via the plurality of support units.

[0042] According to a preferred development of the present invention, the rotary plate, preferably adjacent to the at least one annular bearing surface, has at least one opening through which at least one of the at least three support units is accessible. In particular, the adjustment means of the support units can be actuated through the opening, whereby the respective support units can be individually adjusted for the best possible support of the rotary plate. Furthermore, it has proven advantageous if the rotary plate is circular and has a diameter that is preferably >4 m.

[0043] Furthermore, it has proven advantageous if the turntable is constructed from several elements, preferably in the shape of a circular sector. This measure avoids particularly large and complex components, and the individual components of the turntable device can also be transported through narrower doors and corridors of existing buildings. This allows for easy retrofitting of rooms with the turntable device, even in existing buildings with such a rotating device.

[0044] Furthermore, it has proven advantageous if the at least three support units have a length along the vertical axis that is less than 50 mm and even more preferably less than 45 mm. These dimensions of the length of the respective support unit ensure that the support units can be incorporated into common screed systems with a layer thickness of between 4.5 cm and 6 cm without having to break through any separating or thermal insulation layers, which would have a negative impact on the thermal and sound insulation.

[0045] A further development of the present invention provides that a room dividing element, in particular a room dividing wall, a wall, a drywall, a wall sign or the like is arranged on the room side of the rotating plate. According to a preferred embodiment, the room dividing wall can divide a room into two sections. By rotating the rotating plate, the respective section can be moved within the room, whereby different scenarios can be set up in the room. For example, one section can represent a sleeping area and another section a living area, whereby the living area or the sleeping area can be rotated or moved within the room as desired. For example, both the bedroom and the living room can be positioned in front of a window or a balcony, whereby the use of the space can be designed in a much more versatile way and a spatial location of the room can be used more intensively.For example, if the location of a room offers a particularly spectacular view, the same view can be enjoyed both during the day from the living area and at night from the bedroom. Furthermore, the rotating device can provide additional entertainment by implementing smooth, dynamic, and / or continuous rotations or movement patterns through the drive mechanism. Due to the special use of the rotating device in a building floor element of a room, the rotating device can also be referred to as a building floor rotating device.

[0046] A preferred development of the present invention provides for at least one socket to be arranged on the room side of the turntable. The socket provides a voltage source for furnishings on the turntable and is more preferably supplied with electrical current, in particular mains voltage, via the slip ring unit and the brush unit.

[0047] A further aspect of the present invention relates to a rotary plate arrangement with a previously described rotating device and a substrate, preferably a building floor element, in particular a screed floor, wherein the at least three section units and the rotary bearing unit are embedded and supported in recesses in the substrate.

[0048] According to a preferred embodiment of the present invention, the substrate is a floating screed.

[0049] A further development of the turntable arrangement can comprise at least one driverless vehicle that can travel over the ground and the spatial side of the turntable of the at least one rotating device. The at least one driverless vehicle can drive onto and off the at least one rotating device. A controller can control both the at least one driverless vehicle and the at least one rotating device in a synchronized manner. The networked control of the at least one turntable and the at least one driverless vehicle can create a type of ecosystem that has considerable potential for use.

[0050] The proposed rotating device or the proposed turntable arrangement also opens up entirely new possibilities for optimizing living space for people with disabilities. In this case, the control of everyday configurations via voice control can be particularly beneficial. Voice commands that trigger a degree, speed, and stop commands could also make operation significantly more user-friendly. It is conceivable, for example, to equip the turntable with a remote control and / or control elements. This, for example, can also be used in combination with at least one control element to meet corresponding safety criteria. An exemplary embodiment of the present invention is described in detail below with reference to the accompanying drawing. They show:

[0065] Figure 16 shows a further development of the turntable arrangement with several driverless vehicles.

[0066] Identical or functionally identical parts or features of a preferred embodiment of the invention are identified by the same reference numerals in the following detailed description of the figures. Furthermore, not all identical or functionally identical parts or features are provided with a reference numeral in the figures.

[0067] Figure 1 shows a rotating device 1 for integration into a

[0068] Subsurface 5 (see Figure 15), which in the preferred embodiment described here is a floating screed floor. The rotating device 1 for integration into a subsurface has several support units 20, a rotating plate 40, a rotating bearing unit 60 and at least one drive device 80, wherein the drive device 80 in Figure 1 is partially concealed by the rotating plate 40.

[0069] The rotating plate 40 can be in the form of a circular turntable that extends at least over the circular surface. The rotating plate 40 is rotatably supported by the rotating bearing unit 60 along a rotational axis Z, wherein the rotational axis Z corresponds to the rotational axis of the rotating plate 40.

[0070] According to Figure 2, the rotating plate 40 further comprises a spatial side 41 and a bearing side 42 opposite the spatial side 41 along the rotation axis Z. When the rotating device 1 is used as intended, the bearing side 42 faces the base 5 and the spatial side 41 faces away from the base.

[0071] The rotating plate 40 can—as can be seen from Figures 1 and 3—be composed of a plurality of elements 45, wherein the elements 45 can be shaped like a circular sector. The size of the circular sectors of the respective elements 45 is preferably the same.

[0072] The rotating plate 40 or the elements 45 can be made of an elastic material, whereby the rotating plate 40 can be designed in the manner of a flexible membrane or pliable plate. The rotating plate 40 can follow unevenness of the ground through deformation and follow the settlement behavior of the ground 5. Furthermore, the rotating plate 40 can comprise a frame structure 46 that is arranged on the bearing side 42 of the rotating plate 40. The frame structure 46 can be formed from a plurality of inner and outer frames 47, 48.

[0073] In the illustrated embodiment, an inner frame 47 and an outer frame 48 each form a frame skeleton section corresponding to the circular sector of the elements 45.

[0074] The frames 47, 48 and / or the frame skeleton sections can be connected to one another by means of mutually corresponding form-locking elements 49, which can form a puzzle-like form-lock between adjacent frames 47, 48 and / or the respective adjacent frame skeleton sections.

[0075] In each case, a frame skeleton section connects two elements 45, wherein the frame skeleton section is preferably arranged centrally between two elements 45 in the circumferential direction around the axis of rotation Z.

[0076] The elements 45 can be screwed onto the frame 46.

[0077] Figures 4 to 7 show enlarged views of the rotary bearing unit 60. The rotary bearing unit 60 comprises a slip ring unit 70 and a brush unit 75 cooperating with the slip ring unit 70.

[0078] The slip ring unit 70 and the brush unit 75 are configured to supply the rotating plate 40 with an electrical current. For this purpose, the slip ring unit 70 can be connected to a power source, preferably the power grid, and preferably has two sliding contacts, which even more preferably transmit the phase and neutral conductors.

[0079] The brush unit 75 preferably comprises at least two brushes that are electrically connected to the sliding contacts of the slip ring unit 70. The brush unit 75 can be connected to a control unit (not shown) and the at least one drive device 80 by means of electrical lines (not shown).

[0080] The pivot bearing unit 60 further comprises a base part 61, a rotary plate part 62, and a bearing 63. The bearing 63 rotatably supports the rotary plate part 62 on the base part. The bearing 63 can also form the grounding or protective conductor. The pivot bearing 60 supports the rotary plate 40 via the bearing 63, wherein the bearing 63 can be designed as a plain bearing.

[0081] The base part 61 can be fastened to the base 5 and can specify the positioning of the rotation axis Z. By means of the bearing 63, the rotary plate part 62 is rotatably supported on the base part, wherein a relative movement of the rotary plate part 62 along the rotation axis Z with respect to the base part 61 is possible, on the one hand to achieve tolerance compensation and on the other hand to be able to compensate for any movements, such as settling behavior.

[0082] The base part 61 can, for example, be arranged directly or indirectly on a solid floor or a concrete ceiling, or can be arranged floating in the subfloor, in particular the screed. The base part 61 can be screwed, clamped and / or glued in for fastening. The pivot bearing unit 60 can further comprise a cover 64 and at least one connecting piece 65, wherein the at least one connecting piece 65 connects the cover 64, the elements 45 and the frame structure 46 to one another. For this purpose, the connecting piece 65 can be designed in a stepped manner.

[0083] In particular, it can be seen from Figure 7 that a plurality of connecting pieces 65 are arranged around the axis of rotation Z, whereby in particular the component size of the respective connecting piece 65 can be reduced.

[0084] Furthermore, as can be seen from Figures 6 and 7, the rotary bearing unit 60 or the cover 64 can have a radially aligned recess 66 with respect to the axis of rotation Z, which makes it possible to guide conductors and cables from the slip ring unit 70 and the brush unit 75 to the at least one drive device 80. As can be seen from Figure 6, the radially aligned recess 66 can extend over the elements 45 of the rotary plate 40. A rotary bearing can be provided so that the slip ring unit and brush unit can run smoothly in alignment with one another.

[0085] Figures 8-11 show different views of one of the support units 20.

[0086] According to Figure 1, the support units 20 are arranged distributed over the circumference within the circular area around the rotation axis Z. Overall, several groups of support units 20 can be arranged in a circle around the rotation axis Z at different radii. Each group can comprise a plurality of support units 20, wherein the number of support units 20 in the groups can be different. The support units 20 of each group are preferably arranged circumferentially symmetrically.

[0087] In the illustrated embodiment according to Figure 1, a first group comprises five support units 20, a second group comprises eleven support units 20 and the radially outer third group comprises fifteen support units 20.

[0088] With reference to the accompanying Figures 8 to 11, it can be seen that the respective support unit 20 comprises a housing 25 and a rolling bearing element 30. The respective support unit 20 is a separate component that can be inserted into a recess 6 (see Figure 15) of the base 5. The respective support units 20 are thus not directly connected to the other components of the rotating device 1, but only indirectly via the base.

[0089] The respective support unit 20 is arranged along a vertical axis ZI, wherein the vertical axis ZI is preferably oriented parallel to and spaced from the rotation axis Z.

[0090] The housing 25 can - as shown - be sleeve-shaped, wherein the axis of symmetry or central axis of the housing 25 corresponds to the vertical axis ZI.

[0091] Furthermore, the housing 25 comprises a support surface 28, which protrudes radially from the housing 25 at its end in a flange-like manner with respect to the vertical axis. The support surfaces 28 are intended to bear against the base 5 and to transfer the loads of the respective support unit 20 to the base 5. The rolling bearing element 30 is mounted on the housing 25 and can support the rotating plate 40 so that it can rotate relative to the housing 25.

[0092] The rolling bearing element 30 comprises a rolling body 31 designed as a roller, which can, for example, have a rolling body surface made of metal, rubber or plastic, through which the rolling body 31 can roll particularly quietly on the rotating plate 40.

[0093] Furthermore, the respective support unit 20 can comprise an adjustment means 32, by means of which the rolling bearing element 30 is movable along the vertical axis ZI relative to the housing 25. The adjustment means 32 makes it possible to compensate for any unevenness in the ground.

[0094] In the illustrated embodiment, the adjustment means 32 comprises a screw sleeve 34 that can be screwed into the housing 25. The rolling bearing element 30 is rotatably supported in the screw sleeve 34, and by rotating the screw sleeve 34 in the housing 25 about the vertical axis ZI, the rolling bearing element 30 can be moved relative to the housing 25 along the vertical axis ZI.

[0095] Furthermore, it can be seen from Figures 8-11 that a fixing means 33 is provided, by which the adjusting means 32 can be locked. The fixing means 33 can comprise a lock which, for example, projects from the screw sleeve 34 into an axial groove on an inner circumferential surface of the housing 25. The fixing means 33 can also comprise a clamping screw, a bolt, or a mechanical lock designed as desired by the person skilled in the art. The rolling bearing element 30 protrudes - as can be seen in Figures 8 and 10 - from the housing 25 in the vertical axis ZI and, according to Figure 8, can roll on a bearing surface 44 on the bearing side 42 of the rotary plate 40.

[0096] The respective bearing surface 44 on the bearing side 42 of the rotating plate 40 is annular and is arranged concentrically to the rotation axis Z. The position of the respective bearing surface 44 corresponds to the respective group-wise arrangement of the support units 20.

[0097] As can be seen particularly from Figure 1, the annular bearing surfaces 44 are formed by the frame structure 46 of the rotating plate 40, wherein the frame structure 46 or the frames 47, 48 comprise corresponding circular arc-shaped sections which form the bearing surface 44.

[0098] At the butt joints between two adjacent frames 47, 48, the frames 47, 48 can have an arrow-shaped geometry.

[0099] Due to these inclined transitions at the butt joints in the area of ​​the respective bearing surface 44, the preferably large support rollers 30 can roll smoothly over the bearing surface 44. This contributes in particular to the smooth running of the rotary plate 40.

[0100] The drive device 80 is shown in detail in Figures 12-14, where different views of the drive device 80 designed as an assembly are shown.

[0101] The drive device 80 comprises a frame 82. The drive device 80 can be removably attached as an assembly by means of the frame 82 to the spatial side 41 of the rotary plate 40 and preferably comprises a drive 90 and a friction wheel 84.

[0102] Furthermore, the drive device 80 can comprise a decoupling device 86, which preferably mechanically decouples the friction wheel 84 and / or the drive 90 from the rotating plate 40 or the frame 82 in terms of vibration. This suppresses the transmission of running noise from the friction wheel 84 to the rotating plate 40. Furthermore, a corresponding design of the decoupling device 86 can generate a contact force that presses the friction wheel 84 against the base 5.

[0103] The decoupling device 86 can, for example, comprise an arm 88 pivotable about a pivot axis X. The drive 90 and also the friction wheel 84 driven by the drive 90 can be arranged on this arm 88. Furthermore, a spring and / or damper unit 92 can dampen and / or resiliently support the arm 88 relative to the frame, so that the friction wheel 84 can perform a spring-loaded and / or damped pivoting movement, which is indicated in Figure 12 by a double arrow.

[0104] The friction wheel 84 passes through the rotating plate 40 or the respective element 45 of the rotating plate 40 in a recess 48 and can roll onto the base 5. To reduce running noise, the friction wheel 84 can be designed as a tire and / or have a tread made of rubber, plastic, or the like.

[0105] As can also be seen from Figures 1 and 3, the rotating device 1 can comprise one or more drive devices 80. Not shown in the figures is the possibility of a control unit being provided. The control unit is preferably arranged on the rotating plate 40 and can, for example, receive control commands from a remote control or a higher-level system. The control unit can convert the control commands into a movement of the rotating plate 40 by means of the drive devices 80.

[0106] Figure 15 shows a section through a turntable arrangement with the previously described rotating device 1 and the base 5, wherein it can be seen that the support units 20 are each individually inserted into a recess 6 in the base 5. The support units 20 can either be inserted loosely into the respective recess 6 or fastened in the recess 6 by fastening means (not shown). For example, the support units 20 can be glued and / or clamped into the respective recess 6.

[0107] The pivot bearing unit 60 is inserted into a recess 7 and can also be fastened there.

[0108] The substrate 5 is a floating screed floor, which may be laid on a thermal insulation layer 12. A separating layer 11 may be provided between the thermal insulation layer 12 and the screed. Reference numeral 10 denotes a solid floor, e.g., a concrete ceiling.

[0109] On the room side 41 of the rotating plate 40, the rotating device 1 has a room divider element 58. Furthermore, a socket can be provided, which in the illustrated embodiment is arranged on the room divider element 58. The socket 57 is supplied with mains power via the slip ring unit 70 and the brush unit 75. Furthermore, a piece of furniture 56 can be removed from Figure 15, which is positioned such that the at least one drive device 80 is arranged concealed in the room.

[0110] Figure 16 shows a further development of the turntable arrangement with several previously described rotating devices 1 and several, preferably driverless, vehicles 100 that can travel over the ground 5. The vehicles 100 can drive up and down onto the respective rotating device 1. A controller (not shown) controls both the driverless vehicles 100 and the respective rotating device 1, whereby a coordinated or synchronized movement can be generated.
