Description

[Technical Field]

[0001] The present invention relates to a rotating device for integration into a subfloor, preferably a floor element of a building, in particular a screed floor, having the features of claim 1, and to a rotating plate assembly with such a rotating device having the features of claim 24. [Background technology]

[0002] Spinning devices are already known from the prior art in various embodiments, for example spinning plates, turntables and for various other applications, for example spinning plates are popular attractions in amusement parks as spinning disks or merry-go-rounds.

[0003] Rotating equipment with large diameters and high static loads is often large in design and is often complex, heavy and significantly costly. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] International Publication No. 98 / 30424 Summary of the Invention [Problem to be solved by the invention]

[0005] For example, Patent Document 1 shows a rotating plate device for supporting a large static load. The rotating plate is provided with a base plate and a rotating plate that can rotate relative to the base plate. The rotating plate is attached to the base plate via support bearings arranged on the outer periphery, and the base plate is supported by a subfloor. Because the rotating plate is arranged away from the subfloor, the structural height of the rotating device is relatively high, and in order to reach the rotating plate, a step at the end of the rotating plate must be overcome. In particular, when such a rotating plate device is incorporated into a building, such a step becomes a dangerous location.

[0006] The present invention addresses this issue. Starting from this prior art, the object of the present invention is to propose an improved rotating plate device that overcomes the drawbacks known from the prior art, which can be retrofitted into existing buildings and integrated as flush as possible into the floor elements of the building, thereby creating variable spaces. [Means for solving the problem]

[0007] These problems are solved by a rotating plate device for integration into a subfloor, preferably a floor element of a building, in particular a screed floor, having the features of claim 1 and a rotating plate assembly having the features of claim 24.

[0008] Further advantageous developments of the invention are set forth in the dependent claims. The rotating plate device according to the invention, for integration into a subfloor, preferably a floor element of a building, in particular a screed floor, having the features of claim 1, comprises at least three support units arranged circumferentially within a circular area around a rotation axis and individually insertable into recesses in the subfloor. The rotating device further comprises a rotating plate extending over at least the circular area and having a clearance side and a bearing side opposite the clearance side. A rotary bearing unit and at least one drive unit are also provided, the rotating plate being rotatably mounted on the rotation axis by the rotary bearing unit. The at least three support units separately from the rotary bearing unit support the rotating plate on its bearing side for rotational movement on a vertical axis in the direction of the rotation axis, and the drive unit is configured to rotate the rotating plate around the rotation axis.

[0009] The at least three support units and rotary bearing units according to the present invention are not directly connected to one another. They can be individually and independently inserted into recesses in a subfloor, in particular a standard screed floor with a floating floor, and are then positioned therein. Thus, the at least three support units and rotary bearing units are indirectly connected to one another by the subfloor, thereby enabling, for example, the floor of an existing building, in particular a screed floor, to be used as a support structure, creating a highly flexible system in terms of size and load-bearing capacity using simple means, which can be easily retrofitted to existing buildings with only a small structural height. The proposed rotary device is therefore resource-saving, flexible, efficient, and widely applicable. By incorporating the at least three support units and rotary bearing units into a subfloor, in particular a floor element, and more preferably a screed floor, all load-side and natural subsidence phenomena can be flexibly compensated for. Furthermore, in buildings the physical properties of the building in the field of thermal insulation and sound insulation change only slightly, so that the proposed rotating device is suitable for living, sleeping and working spaces.

[0010] The rotary device is therefore suitable not only for retrofitting but also for planned new buildings and their corresponding combinations. One advantage to be highlighted compared to known prior art is that the damage to the subfloor, in particular the screed, is small and limited, so that the subfloor, in particular the screed, only loses a small amount of its load-bearing capacity, or is not even destroyed. Furthermore, if necessary, the subfloor can be consolidated in the area of the rotary device with a fabric, which is preferably troweled. The fabric can also be used to consolidate the subfloor over a circular area, preferably over a large area.

[0011] The rotating device accommodates completely different settlement and extension behavior. The height level of the subfloor, especially the finished floor, can be controlled relative to the space side of the rotating plate, whereby the proposed solution meets the quality and appearance requirements of today's buildings.

[0012] Another advantage is that the existence of the proposed individual and easy-to-use rotating device allows new, very compact and attractive home and workplace concepts to emerge. Thus, more individual possibilities are created in less space. Due to its wide availability, the rotating device can also serve as a replacement for very large doors. Furthermore, the rotating device can also be used in storage spaces and / or in entry and exit doors, for example, although the listed applications are not limited to the above examples.

[0013] One development of the invention provides that the at least one drive device is arranged above and / or below the rotating plate, so that the at least one drive device rotates together with the rotating plate around the rotation axis during rotation of the rotating plate.

[0014] According to a preferred development of the invention, the at least one drive is arranged substantially on the space side of the rotating plate, so that even if the drive has to be arranged (at least primarily) on the space side of the rotating plate, the space side of the rotating plate can be arranged substantially flush with the subfloor.

[0015] In an alternative embodiment, at least one drive unit can be arranged substantially on the bearing side, thereby making the space side of the rotating device barrier-free. Such a rotating device can be used, for example, as a dance floor, show floor or presentation floor.

[0016] Furthermore, it is possible to rigidly connect the drive to the subfloor and drive the rotating plate. Combinations of the aforementioned drives are also possible. Particularly for very large rotating plates, it may be advantageous to combine at least one drive on the rotating plate with a drive on the subfloor. The drive, which is fixedly arranged on the subfloor below the platform, does not rotate together with the at least one drive unit on the rotating plate against the other. Nevertheless, the two drives complement each other through appropriate synchronization. In this case, an additional friction surface or friction lining must be provided, for example, on the frame structure on the bearing side of the rotating plate, for the at least one drive operating together below the platform. These drives can also cooperate with the bearing areas (bearing surfaces) of the frame structure.

[0017] Such a combination, or locating the drive only on the subfloor, can be particularly advantageous if the drive gets in the way above and, for example, in ceilings with exposed wooden beams or solid or concrete ceilings are combined with a floating screed, in which case the drive can in most cases be provided on the bearing side of the rotating plate or on the subfloor without any problems.

[0018] Preferably, the at least one drive unit can be arranged concealed in a fixture, such as a cupboard, dresser, couch, bed, or the like, so that the appearance of the space is not obstructed by the drive unit protruding into the space. Alternatively, the at least one drive unit can be arranged concealed in a space-dividing element, such as a wall, wall panel, or the like.

[0019] A preferred development of the invention provides that 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 on a subfloor. Furthermore, the friction wheel can be designed as a tire and / or, in a possible embodiment, can have a tread made of plastic or rubber. This can reduce the running noise of the friction wheel and also ensure sufficient adhesion of the friction wheel to the subfloor even with slight irregularities in the subfloor.

[0020] According to another embodiment of the invention, the friction wheel penetrates the rotating plate through the friction wheel recess. The friction surface and the friction wheel or its bearing and / or drive are preferably arranged on opposite sides of the rotating plate. The friction wheel can therefore have a diameter that is significantly larger than the thickness of the rotating plate, which on the one hand allows for a simple structure of the rotating device, and on the other hand allows the friction wheel of at least one drive device to apply a force large enough to rotate the rotating plate around the rotation axis.

[0021] According to a preferred embodiment of the present invention, the drive unit can be detachably mounted as a unit on the space side of the rotating plate. Furthermore, the drive unit can include a base, which preferably includes a decoupling device that vibratory-mechanically decouples the friction wheel and / or the drive unit from the rotating plate. This prevents the transmission of the friction wheel's running noise to the rotating plate, and by appropriately designing the decoupling device, it is possible to ensure that the friction wheel is pressed against the friction surface with a predetermined pressing force.

[0022] Furthermore, it has proven advantageous if a slip ring unit and a brush unit cooperating with the slip ring unit are provided. The slip ring unit and the brush unit can supply current to the rotating plate. The slip ring unit and the brush unit transmit a power supply, i.e., for example, 230 V at 50 Hz, with which conventional electrical devices can be operated on the rotating plate, for example, to generate light, media devices, etc. Additionally, the voltage supply can provide the necessary energy for the drive device.

[0023] The rotary bearing unit preferably includes a slip ring unit. The brush unit can be removably attached to the rotary plate, so that replacement of the brush unit can be realized without much effort.

[0024] Preferably, the rotary bearing unit further includes a base member and a rotary plate member. The rotary plate member is rotatably supported on the base member via a bearing, and more preferably, the rotary plate member is displaceable relative to the base member along the rotation axis. A special feature of the rotary bearing unit is that the base member, which is fixed to the ceiling slab, has an important special feature. In this case, the rotation axis Z is rigidly fixed to the subfloor or building, and the design of the rotary plate can naturally compensate accordingly for the special features of a floating screed placed on a thermal insulation and moisture barrier. This specifically means that if the screed settles due to its own weight and corresponding uneven loads from use and undergoes slight deformation over time, these changes can be automatically compensated for. In this case, it may be necessary for the rotation axis of the rotating device to be stress-freely compensated for by geometric changes due to settlement and distortion relative to the rotation axis Z of the rigidly fixed part. In this case, slight wobble may occur. Also, and in particular, according to a preferred embodiment, the rotating plate can be made from a special pressure-resistant sliding material made of plastic in this case, since it is designed as a flexible membrane that distributes the load over the support unit so that this change in geometry can be fully compensated for via the connecting pieces.

[0025] In special cases, especially when several rotating devices are mounted on a subfloor, in particular a screed, it may also be advantageous architecturally if the rotary bearing unit is also attached to the subfloor, in particular to the raised portion of the screed. This is advantageous in order to avoid stresses between the structural joints between the rotary shaft and the respective rotary plates at the transition to the floor material fixed to the subfloor. In this case, no positive and / or force-locking connection is made with the solid structure, but only with the raised portion of the subfloor itself.

[0026] One of the advantages of the rotating device is found in the joint area between the subfloor and the rotating plate. This joint can be kept relatively small and is very tolerant with regard to possible height deviations and expansion coefficients, since the rotating plate is a relatively soft membrane supported by different numbers of support units depending on the loads of the intended use. This area therefore offers many advantages both technically for barrier-free transitions and visually in terms of qualitative and device-specific aspects.

[0027] A preferred development of the invention provides for a control unit to be provided, which is configured in particular to execute corresponding control commands with the drive or to control the drive. Furthermore, the control unit is preferably remotely controllable and can receive control commands wirelessly or via a wired connection via the slip ring unit and the brush unit cooperating with the slip ring unit. The control commands can be transmitted to the control unit via at least one separate conductor or modulated onto one or more current-carrying conductors, for example in the form of an ASi bus system.

[0028] According to a preferred development of the invention, the drive device comprises an electric drive for generating the rotation of the rotating plate around the rotation axis, which can drive the rotating plate by many known drive types, including by way of example gear drives, chain and belt drives, linear motors (LIM / LSM), but this list is not exhaustive.

[0029] It should be mentioned here that it is also conceivable for the drive device to be hydraulically or pneumatically driven. Furthermore, one development of the invention provides that at least one of the at least three support units includes a rolling bearing element supported by the housing. The rolling bearing element includes rolling elements movably arranged in the housing, the rolling elements preferably protruding from the housing, and via which the rotating plate is held supported by the housing. During rotation of the rotating plate, the rolling elements roll on the rotating plate.

[0030] The rolling elements may include, for example, rollers or balls, and may further have a rolling element surface made of metal, rubber or plastic, which allows the rolling elements to roll on the rotating plate without any particular noise.

[0031] To further optimize the rolling behavior of the rolling elements, the rotation axis of each rolling element can be inclined so that the outer diameters of the inner and outer rollers relative to the rotation axis correspond to the inner and outer raceways of each rolling element when the rotation speed is exactly the same. This allows a relatively large load to be transmitted to the rolling elements, improving the rolling behavior insofar as unpleasant squealing and / or frictional noise is avoided. Furthermore, it can be advantageous if the rollers, especially those close to the rotation axis, are designed spherically to avoid any running noise that may occur.

[0032] Furthermore, one development of the invention provides that at least one of the at least three support units includes an air or gas bearing means. The air or gas bearing means preferably includes a housing and is more preferably designed to keep the rotating plate separated from at least one of the at least three support units by a thin gas or air film. The stick-slip-free and friction-free movement between at least one of the at least three support units and the bearing side of the rotating plate allows for particularly smooth movement of the rotating plate. For example, such a rotating plate can be moved by hand and / or the power of the drive device can be reduced. This also reduces the noise generated when the rotating plate rotates.

[0033] It has also proven to be advantageous if the housing is provided with support areas (support surfaces). In a preferred embodiment, the housing can be designed in the form of a sleeve, and the support areas can protrude from the housing in the form of flanges. The housing is supported on the subfloor via the support areas. Furthermore, the housing can have one or more transverse and / or longitudinal corrugations on its outer mantle surface, which allow the support units to be inserted like dowels into respective recesses in the subfloor.

[0034] Furthermore, it has proven advantageous if the support unit comprises attachment means by which the support unit can be attached to the subfloor. For example, one or more clamping screws or clamping claws can be provided.

[0035] According to a preferred development of the invention, adjustment means are provided by which the rolling bearing element can be adjusted in the vertical axis of the support unit. It is particularly preferred if the rolling bearing element is adjustable in the vertical axis by means of the adjustment means relative to the housing of the support unit. The adjustment means make it possible to compensate for any unevenness in the subfloor in order to ensure uniform support over the circumference of the rotating plate and very quiet operation.

[0036] The adjustment means may further comprise a sleeve movable in an up-down axis relative to the housing, the sleeve being fixed in position relative to the housing by corresponding fixing means, for example the sleeve may be a threaded sleeve that can be screwed into the housing, the fixing means preventing rotation of the sleeve relative to the housing.

[0037] Furthermore, it has proven advantageous if the rotating plate has at least one, preferably ring-shaped, bearing area on the bearing side, which can be arranged concentrically with the rotation axis.

[0038] The rotating plate preferably has a plurality of bearing areas on the bearing side that are arranged coaxially with one another around the rotation axis, thereby allowing a number of support units to be arranged circumferentially and at different radii with respect to the rotation axis, so that the weight of the rotating plate and an object placed on the rotating plate can be evenly distributed and transmitted to the subfloor via the multiple support units.

[0039] According to a preferred development of the invention, the rotating plate preferably has at least one opening adjacent to the at least one ring-shaped bearing area and through which at least one of the at least three support units can be accessed. In particular, adjustment means of the support units can be actuated through the opening, so that each support unit can be adjusted individually in order to support the rotating plate as best as possible.

[0040] Furthermore, it has proven to be advantageous if the rotating plate is circular and preferably has a diameter of >4 m. Furthermore, it has proven advantageous if the rotating plate is formed from a plurality of preferably sector-shaped elements. This measure avoids particularly large and complex parts, and also makes it possible to transport the individual components of the rotating plate device through narrow doors and corridors of existing buildings. This makes it possible to easily retrofit the rotating plate device with such a rotating device into spaces even in existing buildings.

[0041] Furthermore, it has proven advantageous if the at least three support units have a length in the vertical axis of less than 50 mm, more preferably less than 45 mm. These dimensions of the length of each support unit allow them to be accommodated in common screed systems with layer thicknesses of 4.5 cm to 6 cm, without the need to punch out any separating or insulating layers that may be present, which would adversely affect the thermal and sound insulation properties.

[0042] One development of the present invention contemplates that a space partition element, in particular a space partition wall, fence, wall, drywall, or wall panel, etc., is arranged on the space side of the rotating plate. According to a preferred embodiment, the space partition wall can divide a space into two parts. By rotating the rotating plate, each part within the space can be moved, thereby creating various scenarios within the space. For example, one part can be a sleeping area and another part a living area, and the living or sleeping area can be rotated or moved within the space as desired. For example, both a bedroom and a living room can be positioned in front of a window or balcony, thereby enabling diverse use of the space and focusing on one spatial location within the space. For example, if a spatial location offers a particularly good view, the same view can be enjoyed from the living area during the day and from the sleeping area at night. Furthermore, the rotating device can provide additional enjoyment by realizing soft, dynamic, and / or continuous rotation or movement patterns using a drive device. Based on the specific use of the rotating device in a building floor element of a space, the rotating device can also be called a building floor rotating device.

[0043] A preferred development of the invention provides for at least one outlet arranged on the space side of the rotating plate, which provides a voltage source for the fixtures on the rotating plate and is further preferably supplied with current, in particular with a supply voltage, via a slip ring unit and a brush unit.

[0044] Another aspect of the invention relates to a rotating plate assembly comprising the aforementioned rotating device and a subfloor, preferably a floor element of a building, in particular a screed floor, in which at least three subunits and a rotating bearing unit are supported in recesses in the subfloor.

[0045] According to a preferred embodiment of the present invention, the subfloor is a floating screed. One development of the rotating plate assembly can include at least one unmanned vehicle that can travel on the subfloor and the open side of the rotating plate of the at least one rotating device. The at least one unmanned vehicle can travel toward and away from the at least one rotating device. A controller can synchronously control both the at least one unmanned vehicle and the at least one rotating device. Through networked control of the at least one rotating plate and the at least one unmanned vehicle, a type of ecosystem with great potential can be created.

[0046] The proposed rotating device or the proposed rotating plate assembly also opens up completely new possibilities for optimizing living spaces for people with disabilities. Here, controlling daily environmental settings by voice control can be particularly useful. Voice commands triggering degrees, speed and stop commands can also make operation much more user-friendly. For example, it is conceivable to provide the rotating plate with a remote control and / or operating elements. For example, in combination with at least one operating element, the corresponding safety standards can be met.

[0047] Exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. [Brief explanation of the drawings]

[Figure 16] FIG. 10 shows a development of a rotating plate assembly with multiple unmanned vehicles. DETAILED DESCRIPTION OF THE INVENTION

[0049] In the following detailed description of the figures, like or functionally similar parts or features of preferred embodiments of the present invention are indicated with like reference numerals. Furthermore, not all like or functionally similar parts are labeled with reference numerals in the figures.

[0050] Figure 1 shows a rotating device 1 for incorporation into a sub-floor 5 (see Figure 15), which in the preferred embodiment described here is a floating screed floor. The rotating device 1 for incorporation into a sub-floor comprises a plurality of support units 20, a rotating plate 40, a rotation bearing unit 60, and at least one drive device 80, which in Figure 1 is partially covered by the rotating plate 40.

[0051] The rotating plate 40 may have the shape of a circular rotating disk extending over at least a circular area. The rotating plate 40 is rotatably mounted and held by a rotary bearing unit 60 on a rotation axis Z, which corresponds to the rotation axis of the rotating plate 40.

[0052] 2, the rotating plate 40 has a space side 41 and a bearing side 42 located opposite the space side 41 along the rotation axis Z. When the rotating device 1 is used as intended, the bearing side 42 faces the subfloor 5 and the space side 41 faces away from the subfloor.

[0053] 1 and 3, the rotating plate 40 may be composed of a plurality of elements 45, and the elements 45 may be sector-shaped. The size of the sector of each element 45 is preferably the same.

[0054] The rotating plate 40 or the element 45 can be made of an elastic material, so that the rotating plate 40 can be designed like a flexible membrane or a bendable plate. The rotating plate 40 can follow the irregularities of the subfloor 5 by deformation and can follow the subsidence behavior of the subfloor 5.

[0055] Additionally, the rotating plate 40 may include a frame structure 46 disposed on the bearing side 42 of the rotating plate 40. The frame structure 46 may be formed from a plurality of inner frames 47 and outer frames 48.

[0056] In the exemplary embodiment shown, the inner frame 47 and the outer frame 48 each form a frame structure portion corresponding to the sector of the element 45 . The frames 47, 48 and / or frame structure portions can be connected to each other by corresponding shape-connecting elements 49 that can form a puzzle-like shape connection between adjacent frames 47, 48 and / or respective adjacent frame structure portions.

[0057] Each framework section connects two elements 45 and is preferably centrally located between the two elements 45 in the circumferential direction around the axis of rotation Z. The element 45 can be secured to a frame structure 46 by screws.

[0058] 4 to 7 show enlarged views of the rotary bearing unit 60. The rotary bearing unit 60 includes a slip ring unit 70 and a brush unit 75 that cooperates with the slip ring unit 70.

[0059] The slip ring unit 70 and the brush unit 75 are configured to supply current to the rotating plate 40. For this purpose, in particular the slip ring unit 70 can be connected to a current source, preferably to a power supply network, the slip ring unit further preferably having two sliding contacts which carry a phase and a neutral conductor.

[0060] The brush unit 75 preferably includes at least two brushes electrically connected to the sliding contacts of the slip ring unit 70. Electrical wires (not shown) can connect the brush unit 75 to a control unit (not shown) and to at least one driver 80.

[0061] Furthermore, the rotary bearing unit 60 includes a base member 61, a rotary plate member 62, and a bearing 63. The bearing 63 supports the rotary plate member 62 on the base member so that it can rotate. The bearing 63 can also form a ground or protective conductor. The rotary bearing 60 supports the rotary plate 40 via the bearing 63, which can be designed as a plain bearing.

[0062] The base member 61 can be attached to the subfloor 5 and can specify the positioning of the rotation axis Z. The rotating plate member 62 is rotationally supported on the base member by means of bearings 63, allowing relative movement of the rotating plate member 62 along the rotation axis Z with respect to the base member 61 in order, on the one hand, to compensate for tolerances and, on the other hand, to be able to compensate for movements such as possible subsidence behavior.

[0063] The base member 61 may be placed indirectly or directly on, for example, a solid floor or concrete ceiling, or may be placed floating on a subfloor, in particular a screed. The base member 61 may be screwed, clamped and / or glued for attachment.

[0064] The rotary bearing unit 60 may further comprise a lid 64 and at least one connecting piece 65, which connects the lid 64, the element 45 and the frame structure 46 to one another. For this purpose, the connecting piece 65 may be designed stepped.

[0065] In particular, it can be seen from FIG. 7 that a plurality of connecting pieces 65 are arranged around the rotation axis Z, which in particular makes it possible to reduce the component size of each connecting piece 65 . 6 and 7, the rotary bearing unit 60 or the lid 64 may have recesses 66 oriented radially relative to the rotation axis Z, which recesses allow conductors and cables to be passed from the slip ring unit 70 and the brush unit 75 to the at least one drive device 80. As can be seen in Fig. 6, the radially oriented recesses 66 may extend across the elements 45 of the rotating plate 40. A rotary bearing may be provided to allow the slip ring unit and the brush unit to rotate in registration with each other.

[0066] 8-11 show different views of one of the support units 20. FIG. According to Fig. 1, the support units 20 are arranged circumferentially distributed within a circular area around the rotation axis Z. Overall, multiple groups of support units 20 can be arranged circularly at different radii around the rotation axis Z. Each group can include multiple support units 20, and the number of support units 20 in a group can vary. The support units 20 in each group are preferably arranged symmetrically in the circumferential direction.

[0067] In the illustrated embodiment according to FIG. 1, the first group includes 5 support units 20, the second group includes 11 support units 20, and the third group located radially outward includes 15 support units 20.

[0068] 8 to 11, it can be seen that each support unit 20 comprises a housing 25 and a rolling bearing element 30. Each support unit 20 is a separate part that can be inserted into a recess 6 (see FIG. 15) in the subfloor 5. Thus, each support unit 20 is not directly connected to other components of the rotating device 1, but only indirectly via the subfloor.

[0069] Each support unit 20 is disposed along a vertical axis Z1, which is preferably oriented parallel to and spaced from the rotation axis Z. The housing 25 may be sleeve-shaped as shown, and the axis of symmetry or center axis of the housing 25 corresponds to the vertical axis Z1.

[0070] Furthermore, the housing 25 includes support areas 28 at its ends, which project in the form of flanges from the housing 25 in the radial direction relative to the vertical axis. The support areas 28 are provided to abut on the subfloor 5 and to transfer the load of each support unit 20 to the subfloor 5.

[0071] The rolling bearing element 30 is attached to and held by the housing 25 and is capable of supporting the rotation plate 40 so as to be capable of rotational movement relative to the housing 25 . The rolling bearing element 30 comprises rolling elements 31 designed as rollers, which may have rolling element surfaces made of, for example, metal, rubber or plastic, which enable the rolling elements 31 to roll on the rotating plate 40 particularly noiselessly.

[0072] Furthermore, each support unit 20 can include adjustment means 32 by means of which the rolling bearing element 30 is movable in a vertical axis Z1 relative to the housing 25. The adjustment means 32 make it possible to compensate for irregularities possibly present in the subfloor.

[0073] In the illustrated exemplary embodiment, the adjustment means 32 includes a threaded sleeve 34 that can be screwed into the housing 25. The rolling bearing element 30 is rotatably supported within the threaded sleeve 34, and rotation of the threaded sleeve 34 within the housing 25 about the vertical axis Z1 allows the rolling bearing element 30 to move relative to the housing 25 along the vertical axis Z1.

[0074] 8 to 11, there is further provided a fixing means 33 by which the adjusting means 32 can be locked. The fixing means 33 can comprise, for example, a lock protruding from the threaded sleeve 34 into an axial groove in the inner mantle 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 one skilled in the art.

[0075] The rolling bearing element 30 projects from the housing 25 on a vertical axis Z1, as can be seen in FIGS. 8 and 10, and can roll on a bearing area 44 on the bearing side 42 of the rotating plate 40 according to FIG.

[0076] Each bearing area 44 on the bearing side 42 of the rotating plate 40 is formed in a ring shape and is arranged concentrically with the rotation axis Z. The position of each bearing area 44 corresponds to the arrangement of each group of support units 20.

[0077] As can be seen particularly well in FIG. 1, the ring-shaped bearing area 44 is formed by a frame structure 46 of the rotating plate 40 , and the frame structure 46 or frames 47 , 48 include corresponding arcuate portions that form the bearing area 44 .

[0078] The frames 47, 48 can have an arrow-shaped geometric shape at the abutment between two adjacent frames 47, 48. These oblique transitions of the abutments in the region of the respective bearing areas 44 allow the preferably large support rollers 30 to roll gently on the bearing areas 44. This contributes in particular to quiet rotation of the rotating plate 40.

[0079] The drive unit 80 is shown in detail in FIGS. 12 to 14, which show different views of the drive unit 80 designed as an assembly. The drive unit 80 includes a mount 82. The drive unit 80 can be removably mounted as an assembly on the space side 41 of the rotating plate 40 by the mount 82, and preferably includes a drive portion 90 and a friction wheel 84.

[0080] Furthermore, the drive device 80 can preferably include a decoupling device 86 that vibratory-mechanically decouples the friction wheel 84 and / or the drive part 90 from the rotating plate 40 or the base 82. This reduces the transmission of running noise from the friction wheel 84 to the rotating plate 40. Furthermore, by designing the decoupling device 86 accordingly, a pressing force can be generated that presses the friction wheel 84 against the subfloor 5.

[0081] The decoupling device 86 may include, for example, an arm 88 that can pivot about a pivot axis X. A drive unit 90 and a friction wheel 84 driven by the drive unit 90 may also be arranged on this arm 88. Furthermore, a spring unit and / or a damper unit 92 may damp and / or resiliently support the arm 88 relative to the platform, thereby allowing the friction wheel 84 to perform a resilient and / or damped pivoting movement as indicated by the double-headed arrow in FIG.

[0082] The friction wheels 84 pass through the rotating plate 40 or each element 45 of the rotating plate 40 in the recesses 48 and can roll on the subfloor 5. To reduce running noise, the friction wheels 84 can be designed as tires and / or have treads made of rubber, plastic, etc.

[0083] As can further be seen from FIGS. 1 and 3, the rotation device 1 may include one or more drive devices 80. Although not shown in the figure, a control unit may be provided. The control unit is preferably arranged on the rotating plate 40 and can receive control commands, for example, from a remote control or a higher-level system. The control unit can convert the control commands into movements of the rotating plate 40 by means of the drive device 80.

[0084] 15 shows a cross-sectional view of the rotating plate assembly with the aforementioned rotating device 1 and subfloor 5, where it can be seen that the support units 20 are individually inserted into one recess 6 each in the subfloor 5. The support units 20 can be loosely inserted into each recess 6 or can be attached to the recesses 6 by attachment means (not shown). For example, the support units 20 can be glued and / or clamped to each recess 6.

[0085] The rotary bearing unit 60 can be inserted into the recess 7 and mounted therein. The subfloor 5 is a floating screed floor that can be laid on an insulating layer 12. A separating layer 11 can be provided between the insulating layer 12 and the screed. Reference number 10 indicates a solid floor, for example a concrete ceiling.

[0086] The rotating device 1 has a space-dividing element 58 on the space side 41 of the rotating plate 40. Furthermore, in the illustrated exemplary embodiment, an outlet can be provided, which is arranged on the space-dividing element 58. The outlet 57 is supplied with a power supply current via a slip ring unit 70 and a brush unit 75.

[0087] Further visible in FIG. 15 is fixture 56, which is positioned such that at least one drive unit 80 is concealed and disposed within the space. 16 shows one development of the rotating plate assembly together with a plurality of the aforementioned rotating devices 1 and a plurality of preferably unmanned vehicles 100 that can travel on a subfloor 5. The vehicles 100 can travel towards and away from each rotating device 1. A controller, not shown, can control both the unmanned vehicles 100 and each rotating device 1, thereby generating coordinated or synchronized movement. [Explanation of symbols]
