The turntable can carry children and drive them to rotate, thereby providing comprehensive training for children's balance and body coordination.

[0003] Existing products such as rotating tables and rotating chairs often have bearings installed at the bottom of their bases. The upper end of the connecting piece is connected to the turntable, and the lower end is rotatably connected to the base by fitting in the bearing. However, the bearing is generally embedded in the bottom of the base after the base is processed and formed. The connecting piece, turntable, and children or other objects placed on the turntable are supported only by the friction between the base and the bearing. The load-bearing capacity of the base is poor, and the bearing is prone to loosening and falling off after long-term use, resulting in risks of children falling or slipping during rotation, which reduces safety.

[0030] like Figure 1-6 As shown, as a first embodiment of the present invention, a rotary support device 100 is provided, comprising a turntable unit 2 and a base unit 1. The turntable unit 2 comprises a supporting structure 21 and a connecting structure 22 connected to the lower portion of the supporting structure 21. The upper portion of the supporting structure 21 is provided with a supporting portion 2111 for a human buttocks, legs, soles of feet, palms, stomach, or an animal or other toy to rest against. The connecting structure 22 comprises a supporting member 221 and a connecting member 222 connected to the supporting member 221. The lower portion of the connecting member 222 is provided with a rotation axis 2222. The base unit 1 includes a base structure 11 for being placed on a supporting surface such as the ground or the floor, and an installation structure 12 arranged on the upper part of the base structure 11. A support interface 10 for abutting against the supporting surface is formed at the lower part of the base structure 11. The installation structure 12 includes an installation channel 110 passing through the base structure 11, at least one bearing member 1133 located in the installation channel 110, and a connecting channel 120 arranged along the center of the bearing member 1133 and passing through the base structure 11. The diameters of the upper opening 1101 and the lower opening 1102 of the installation channel 110 are both smaller than the outer diameter of the bearing member 1133. The turntable unit 2 is connected to the base unit 1 by being sleeved in the connecting channel 120 through the rotating shaft 2222, and can rotate relative to the base unit 1 along the axial direction of the rotating shaft 2222, thereby driving the turntable unit 2 to rotate relative to the base unit 1. The rotation support device 100, since the diameters of the upper opening 1101 and the lower opening 1102 of the installation channel 110 are both smaller than the outer diameter of the bearing member 1133, can support the bearing member 1133 through the friction between the side wall of the installation channel 110 and the outer side of the bearing member 1133, and can also provide more direct and powerful support to the bottom of the bearing member 1133 through the top wall of the lower opening 1102, thereby greatly improving the load-bearing capacity of the base unit 1, and providing more stable support for the rotating shaft 2222 and the turntable unit 2 as a whole. The bottom of the lower end bearing member 1133 is limited by the top wall of the lower opening 1102, and the top of the upper end bearing member 1133 is limited by the bottom wall of the upper opening 1101, so that the installation and positioning structure of the bearing member 1133 is more stable, preventing the bearing member 1133 from falling off relative to the installation channel 110, thereby avoiding the risks of children tipping over or slipping during rotation, and improving safety during use.

[0031] In some specific embodiments, the bearing member 1133 and the base structure 11 are processed and connected as an integrated structure during production, and the bearing member 1133 is firmly wrapped and fixed in the installation channel 110 and cannot move relative to the installation channel 110, thereby improving the stability and reliability of the connection between the bearing member 1133 and the base structure 11.

[0032] like Figure 5 As shown, in some specific embodiments, three bearing members 121 are provided, which provide strong support and load-bearing capacity, further improving the overall load-bearing capacity of the base unit 1. In other embodiments, two or other numbers of bearing members 121 may be provided. The bearing members 121 are stacked and placed along the height direction of the installation channel 110. The bearing members 121 include an outer sleeve that is limited in the height direction of the installation channel 110 and an inner sleeve that is rotatably connected to the inner side of the outer sleeve. The inner sleeve and the outer sleeve are arranged coaxially, and the centers of the inner sleeves are combined to form the connecting channel 120.

[0033] like Figure 5 As shown, in some specific embodiments, the upper part of the rotating shaft 2222 protrudes outward along its circumferential direction to form a limiting platform. The lower end of the rotating shaft 2222 is provided with a docking portion for cooperating with the fastening structure 223. The rotating shaft 2222 can extend into the connecting channel 120 from the upper end of the connecting channel 120, and is clamped between the limiting platform and the fastening structure 2223 through the inner sleeves of each bearing member 121 to limit the height direction relative to the connecting channel 120. When the turntable unit 2 is driven to rotate, the inner sleeves of each bearing member 121 are driven relative to the outer sleeves. The rotational movement realizes the rotational connection between the turntable unit 2 and the base unit 1, and can prevent the axial movement of the rotating shaft 2222 relative to the connecting channel 120, thereby preventing the axial movement of the turntable unit 2 relative to the base unit 1. The rotating shaft 2222 and the connecting channel 120 abut or engage with each other to prevent the radial movement of the rotating shaft 2222 relative to the connecting channel 120, thereby preventing the radial movement of the turntable unit 2 relative to the base unit 1, thereby realizing the installation positioning and rotational connection between the turntable unit 2 and the base unit 1, and the structure is simple and easy to assemble. In this embodiment, the outer wall of the limit platform has the same radius as the outer wall of the upper part of the connecting shaft 2221, and is smoothly connected as a whole, which simplifies the structure. In other embodiments, the outer wall of the limit platform can also be spaced apart from the outer wall of the upper part of the connecting shaft 2221.

[0034] like Figure 5As shown, in some specific embodiments, the fastening structure 223 includes a fastener 2231 and a limiting member 2232. The fastener 2231 has a connecting end 22311 and an operating end 22312 connected to the connecting end 22311. The limiting member 2232 is connected to the connecting end 22311 and the operating end 22312. The docking portion is configured as a docking channel formed by a depression in the end surface of the rotating shaft 2222. The connecting end 22311 extends into the docking channel and is mated with the rotating shaft 2222. After the connection, the upper side of the limiting member 2232 abuts against the lower side of the inner sleeve of the lower end bearing member 121. The docking channel is provided with an internal thread structure, and the connecting end 22311 is provided with an external thread structure. The fastener 2231 and the rotating shaft 2222 are fastened together by the threaded engagement between the external and internal threads, facilitating installation or removal. In this embodiment, the fastener 2231 and the limiting member 2232 are integrally formed, and the structure is simple and practical. In other embodiments, the limiting member 2232 can also be connected only to either the connecting end 22311 or the operating end 22312. The fastener 2231 and the limiting member 2232 can also be respectively set as independent structures, and the limiting member 2232 is mounted on the outside of the connecting end 22311 and limited on the operating end 22312 for detachable connection.

[0035] like Figure 5 As shown, in some specific embodiments, the limit platform is arranged in the upper opening 1101 of the installation channel 110 and is spaced apart from the side wall 1101 of the upper opening, and the limit member 2232 is arranged in the lower opening 1102 of the installation channel and is spaced apart from the side wall of the lower opening 1102. That is to say, during the rotation of the turntable unit 2 relative to the base unit 1, the limit platform does not contact the upper opening 1101, and the limit member 2232 does not contact the lower opening 1102, thereby reducing friction and facilitating the smooth rotation of the turntable unit 2.

[0036] like Figure 2-4 As shown, in some specific embodiments, the support interface 10 is arranged along the circumferential direction of the lower part of the base structure 11, and can support the pressure applied at various angles during the rotation of the turntable unit 2 in a 360° direction, and the outer surface of the base structure 11 is arranged in an arc shape from the top to the bottom, so that during the rotation of the turntable unit 2, the force on each part of the base unit 1 is relatively uniform, so that the structure is stable and strong and not easy to be damaged, which further improves the safety of children's sensory integration training.

[0037] like Figure 3As shown, in some specific embodiments, the base structure 11 includes a base frame 111 at the bottom, a mounting plate 112 at the top, and a base plate 113 arranged along the circumferential direction of the mounting plate 112. The upper end of the base plate 113 is connected to the mounting plate 112 as an integral structure, and the lower end of the base plate 113 is connected to the base frame 111 as an integral structure. The outer surfaces of the mounting plate 112, the base plate 113 and the base frame 111 are smoothly transitioned and connected to form an arc-shaped support structure extending from the top of the mounting plate 112 to the bottom of the base frame 111. The support interface 10 is arranged at the bottom of the base frame 111, and the mounting structure 12 is arranged on the mounting plate 112. The setting of the arc-shaped support structure ensures that the forces on various parts of the base unit 1 are relatively uniform during the rotation of the turntable unit 2, so that the structure is stable and strong and not easy to be damaged. The mounting plate 112 is supported at a certain height by the base frame 111 and the base plate 113, and is arranged at intervals from supporting surfaces such as the ground and the floor to form a spherical groove space on the lower side of the base structure 11 for placing objects.

[0038] like Figure 4 As shown, in some specific embodiments, the lower portions of the base frame 111, mounting plate 112, and base plate 113 are each provided with a plurality of second support members 114 for providing support. The second support members 114 are configured as block-shaped structures that protrude linearly and spaced apart from each other along the lower surface of the base frame 111, mounting plate 112, or base plate 113. The base structure 11 is made of plastic material and formed through injection molding, blow molding, or other production processes to facilitate mass production. The second support members 114 serve to strengthen the structural strength of the base frame 111, mounting plate 112, and base plate 113, thereby improving the stability and load-bearing capacity of the base structure 11. In other embodiments, the second support members 114 may be provided on only one or two of the base frame 111, mounting plate 112, and base plate 113, thereby also strengthening the structural strength of the base structure 11 to a certain extent. The base structure 11 may also be made of other materials such as metal or wood.

[0039] In some specific embodiments, a plurality of second support members 114 are provided, wherein each second support member 114 on the lower surface of the mounting plate 112 includes a second support member 114 having a circular structure and a plurality of second support members 114 having a strip structure and arranged in a clockwise direction with respect to the center of the mounting plate 112. The second support member 114 having the circular structure is coaxially arranged with the connecting shaft 2221, and the radius is set to be larger than the radius of the connecting shaft 2221. The center of the mounting plate 112 extends downward from its lower surface with a mounting base 1121 arranged corresponding to the mounting channel 110, and the mounting structure 12 is provided on the mounting base 1121. Figure 5As shown, the connecting shaft 2221, the mounting channel 110 and the mounting base 1121 are all arranged at an angle to the support interface 10. After the turntable unit 2 is connected to the base unit 1 through the rotating shaft 2222, it is arranged at an angle to the support interface 10 of the base unit 1, so that the turntable unit 2 has a height difference during rotation. When children rotate their bodies while riding on the turntable unit 2, they can not only experience the feeling of horizontal rotation, but also the feeling of rising and falling. This makes the sensory stimulation for children more comprehensive, increases the fun of playing, and can stimulate children's interest in sensory integration training. The angle is set to be greater than 75° and less than 90°, especially greater than 80° and less than 90°, which can ensure the safety of children's sensory integration training and allow children to clearly experience the feeling of rising and falling during rotation. The multiple second support members 114 of the strip-shaped structure are arranged on the inner side of the second support member 114 of the circular structure, and one end is combined with the mounting base 1121, and the other end is combined with the second support member 114 of the circular structure, so that the structure of the mounting plate 112 is more stable and strong. The second support members 114 on the lower surface of the base plate 113 are set to a strip structure, and one end of the second support members 114 of the strip structure is combined with the second support member 114 of the circular structure on the lower surface of the mounting structure 12, and the other end is combined with the flange structure of the edge of the base plate 113, so that the structure of the base plate 113 is more stable and strong, and can provide direct and strong support for the pressure at various angles applied to the base structure 11 by children when sitting on the load-bearing part 2111, thereby avoiding breakage of the mounting plate 112 or the base plate 113. The base frame 111 is configured as a double-ring structure that is coupled to each other at the upper ends, and each second support member 114 on the lower surface of the base frame 111 is configured as a strip structure, and the second support members 114 are arranged in a clockwise direction with the center of the base frame 111, and one end of the second support member 114 is coupled to the outer ring of the double-ring structure, and the other end is coupled to the inner ring of the double-ring structure, so that the structure of the base frame 111 is more stable and strong, and the support interface 10 is arranged at the bottom of the double-ring structure. In this embodiment, an anti-slip pad installed in the double-ring structure is provided, and the bottom of the double-ring structure and the bottom surface of the anti-slip pad together form the support interface 10. In other embodiments, the anti-slip pad can also be provided at the bottom of the double-ring structure, and the support interface 10 can also be completely formed by the bottom of the double-ring structure, or completely formed by the bottom surface of the anti-slip pad. The second support member 114 can also be configured as a curved structure or other shape structure, all of which can be used to strengthen the structural strength of the mounting plate 112.

[0040] like Figure 2 As shown, in some specific embodiments, a hollow structure 1130 is provided on the base plate 113 from its outer surface to its inner surface. On the one hand, it can save materials and production costs. On the other hand, the hollow structure 1130 is connected to the spherical groove space formed on the lower side of the base structure 11 and can be used as a storage channel for the spherical groove space.

[0041] like Figure 3 As shown, in some specific embodiments, the hollow structure 1130 includes a plurality of first hollow channels 1131 arranged along the circumference of the mounting plate 112. The first hollow channels 1131 extend from the vicinity of the base frame 111 toward the vicinity of the mounting plate 112. The first hollow channels 1131 are evenly spaced, and a base member 1133 is formed between two adjacent first hollow channels 1131. The base member 1133 is a plate-like structure, with the upper end of the base member 1133 integrally connected to the mounting plate 112 and the lower end of the base member 1133 integrally connected to the base frame 111. In this embodiment, the first hollow channels 1131 are configured as a fan-shaped structure, with the distance between the two sides of the base member 1133 gradually increasing from the lower end to the upper end. This ensures that the area of ​​the first hollow channels 1131 is maximized while ensuring stable support for the mounting plate 112, thereby reducing production costs and making it more convenient for children to place or remove items into or from the spherical groove space through the first hollow channels 1131.

[0042] In some specific embodiments, the hollow structure 1130 further includes a plurality of second hollow channels 1132 arranged along the circumference of the mounting plate 112. These second hollow channels 1132 extend from near the mounting plate 112 toward the lower end of the base member 1133, further reducing production costs. A base portion 11331 is formed between two adjacent first hollow channels 1131 and second hollow channels 1132. The upper end of the base portion 11331 is integrally connected to the mounting plate 112, and the lower end of the base portion 11331 is integrally connected to the base frame 111.

[0043] In some specific embodiments, the upper ends of the two base portions 11331 arranged on both sides of the first hollow channel 1131 are connected by a circular arc surface transition, and the lower ends of the two base portions arranged on both sides of the first hollow channel 1131 and the base frame 111 are respectively connected by a circular arc surface transition. Compared with the transition connection through two intersecting planes, the force on each part of the mounting plate 112, the base plate 113 and the base frame 111 is more uniform and less prone to damage, and the inner side wall of the first hollow channel 1131 is smoother and less likely to scratch children.

[0044] like Figure 1 As shown, in some specific embodiments, the supporting structure 21 is configured as a disc structure with a simple structure. Figure 6As shown, the bearing structure 21 and the connecting structure 22 are processed and connected as an integral structure during production, and the connection is stable and secure. The supporting member 221 of the connecting structure 22 is wrapped by the lower part of the bearing structure 21, so that the supporting member 221 of the connecting structure 22 is firmly wrapped and fixed in the lower part of the bearing structure 21, and the connecting structure 22 will not fall off from the bearing structure 21, thereby greatly improving the stability and reliability of the connection between the connecting structure 22 and the bearing structure 21, and the safety during the children's sensory integration training process is higher, and it is more suitable for children to carry out sensory integration training. The connecting member 222 and the supporting member 221 are an integral structure, and no additional screws are required for connection, which simplifies the structure. In other embodiments, the bearing structure 21 can also be set as other animal-shaped structures such as fish, pigs, cows, ducks, or other shaped structures such as triangles, polygons, flowers, etc., with richer shapes and better ability to stimulate children's interest in sensory integration training.

[0045] like Figure 5 As shown, in some specific embodiments, the supporting portion 2111 is arranged in an arc-shaped surface to allow children to ride on the supporting portion 2111 and rotate, or place various toys on the supporting portion 2111 to rotate and play, which conforms to the human body structure and is suitable for riding-type sensory integration training. Children have better stability when riding on the supporting portion 2111 and are not likely to fly out of the turntable unit 2 under the action of the centrifugal force of the rotation, further improving the safety of children during sensory integration training.

[0046] like Figure 5 As shown, in some specific embodiments, a wrapping area 213 is provided at the lower portion of the supporting structure 21, and the supporting member 221 is located in the wrapping area 213 and is covered by the outer end surface of the supporting structure 21, so that the supporting member 221 can be limited in the axial direction of the rotating shaft 2222 within the supporting structure 21, thereby preventing the connecting structure 22 from moving relative to the supporting structure 21 along the axial direction of the rotating shaft 2222, and preventing the connecting structure 22 from falling off from the supporting structure 21.

[0047] In some specific embodiments, the connecting member 222 includes a connecting shaft 2221 connected to the support member 221. The lower portion of the connecting shaft 2221 forms the rotation axis 2222. The upper portion of the connecting shaft 2221 is provided with a connecting plate 2223 arranged along the length of the connecting shaft 2221. The upper portion of the connecting shaft 2221 and a portion of the connecting plate 2223 are located within the wrapping area 213 and covered by the outer end surface of the support structure 21. The connecting plate 2223 can be limited within the support structure 21 along the circumference of the rotation axis 2222, preventing the connecting structure 22 from moving relative to the support structure 21 along the circumference of the rotation axis 2222 and preventing the connecting structure 22 from rotating relative to the support structure 21. The connecting structure 22 is made of metal materials such as iron and aluminum, and has a stable and strong structure, which makes the overall structure of the turntable unit 2 stable and has strong load-bearing capacity. The upper part of the connecting structure 22 is completely covered by the lower structure of the supporting structure 21, which can fully wrap and fix the upper part of the connecting structure 22, thereby improving the stability of the connection between the connecting structure 22 and the supporting structure 21. In other embodiments, the upper part of the connecting structure 22 can also be set to be partially covered by the lower structure of the supporting structure 21, and the upper part of the connecting structure 22 can also be firmly wrapped and fixed in the lower structure of the supporting structure 21.

[0048] In some specific embodiments, the support member 221 is configured as a panel structure arranged in the direction corresponding to the arrangement of the support portion 2111. This provides a larger contact area with the support structure 21, thereby preventing the connection structure 22 from axially moving relative to the support structure 21 along the rotation axis 2222, and preventing the connection structure 22 from falling off the support structure 21. A plurality of connecting plates 2223 are arranged at intervals along the circumference of the connecting axis 2221. This provides a larger contact area with the support structure 21, thereby preventing the connection structure 22 from circumferentially moving relative to the support structure 21 along the rotation axis 2222, and preventing the connection structure 22 from rotating relative to the support structure 21.

[0049] like Figure 5-6As shown, in some specific embodiments, the supporting structure 21 further includes a first stopper 214 protruding from the lower surface of the supporting plate 211 and arranged corresponding to the upper portion of the connecting shaft 2221, and a second stopper 215 protruding from the lower surface of the supporting plate 211 and arranged corresponding to the connecting plate 2223. The wrapping area 213 includes a first region 2131 disposed within the lower structure of the supporting plate 211, a second region 2132 disposed within the first stopper 214, and a third region 2133 disposed within the second stopper 215. Support member 221 is wrapped within first region 2131 and covered by the outer end surface of carrier plate 211. The top surface of support member 221 abuts or engages with the top surface of first region 2131, the bottom surface of support member 221 abuts or engages with the bottom surface of first region 2131, and the circumferential side surfaces of support member 221 abut or engage with the circumferential side surfaces of first region 2131, thereby firmly wrapping and securing support member 221 within first region 2131 and preventing axial or radial movement of support member 221 relative to carrier plate 211. A portion of the upper portion of connecting shaft 2221 is wrapped within second region 2132 and covered by the outer end surface of first stopper 214. The circumferential side surfaces of the upper portion of connecting shaft 2221 abut or engage with the circumferential side surfaces of second region 2132, thereby firmly wrapping and securing the upper portion of connecting shaft 2221 within second region 2132 and preventing radial movement of the upper portion of connecting shaft 2221 relative to first stopper 214. Part of the connecting plate 2223 is wrapped within the third region 2133 and covered by the outer end surface of the second stopper 215. One side surface of the connecting plate 2223 abuts or engages with one side surface of the third region 2133, the other side surface of the connecting plate 2223 abuts or engages with the other side surface of the third region 2133, and the end surface of the connecting plate 2223 abuts or engages with the end surface of the third region 2133. This firmly wraps and secures the connecting plate 2223 within the third region 2133, preventing the connecting plate 2223 from circumferential or radial movement relative to the second stopper 215. This ensures that the entire connecting structure 22 is firmly fixed relative to the supporting structure 21, preventing relative movement.

[0050] like Figure 6 As shown, in some specific embodiments, the support structure 21 includes a support plate 211, and a plurality of first support members 212 are provided at the bottom of the support plate 211 for providing support. The first support members 212 are configured as block-shaped structures that are arranged linearly along the bottom surface of the support plate 211 at intervals and protrude from the bottom end surface of the support plate 211. The support structure 21 is made of plastic material and is formed through production processes such as injection molding and blow molding to facilitate mass production. The first support members 212 are used to strengthen the structural strength of the support plate 211, thereby improving the stability and load-bearing capacity of the support structure 21 for supporting children. In other embodiments, the first support members 212 may not be provided, and the support structure 21 may be made of other materials such as metal and wood.

[0051] like Figure 6 As shown, in some specific embodiments, the support plate 211 has an external flange 2113. The external flange 2113 is configured as a boss distributed along the outer periphery of the support plate 211 and extending from the upper surface of the support portion 2111 toward the bottom. This is less likely to scratch children, further improving safety during child training. The end of the first support member 212 is coupled to the inner surface of a portion of the external flange of the support plate 211, which can strengthen the structural strength of the external flange 2113, improve the stability and load-bearing capacity of the external flange 2113 in supporting the child, and prevent the external flange 2113 from breaking. In other words, it strengthens the structural strength of the outer periphery of the support plate 211 and prevents the outer circumferential structure of the support plate 211 from breaking, thereby further improving the overall structural strength of the support structure 21.

[0052] In some specific embodiments, the supporting structure 21 also includes a gripping member 2112 disposed on the supporting plate 211 for gripping when driving the supporting structure 21 to rotate. The supporting portion 2111 is configured as a panel structure formed by the upper surface of the supporting plate 211 in a circumferential direction. When a child is placed on the supporting portion 2111 and rotates, the child can further prevent the child from flying out of the turntable unit 2 under the action of the centrifugal force of the rotation by gripping the gripping member 2112 with his hands, thereby further improving the safety of the child during sensory training. The gripping member 2112 is composed of a portion of the external flange of the supporting portion 2111, simplifying the structure. The height of the gripping member 2112 is higher than the height of the center point of the supporting portion 2111, and the gripping angle is more in line with the human body structure, providing better comfort. As another embodiment of the present invention, gripping channels for the operator's fingers to enter are respectively provided on opposite sides of the supporting plate 211. The gripping member 2112 is arranged on the outside of the gripping channel to facilitate the child's gripping of the gripping member 2112.

[0053] like Figure 7-8As shown, as a fourth embodiment of the present invention, a rotating support device 400 is also provided. The main difference between the fourth embodiment and the first embodiment is that the bearing portion 2111 is configured as a planar structure. The turntable unit 2 is connected to the mounting structure 12 via a rotating shaft 2222 and is arranged perpendicular to the support table surface. It is rotatable relative to the base unit 1 along its axis via the rotating shaft 2222, forming a planar rotating platform device suitable for standing sensory integration training. The second support member 114 is only provided on the lower surface of the mounting plate 112, and the hollow structure 1130 is not provided on the base plate 113. The entire structure of the upper portion of the connecting shaft 2221 and the connecting plate 2223 is located within the wrapping area 213 and is covered by the outer end surface of the supporting structure 21, wherein the entire structure of the upper portion of the connecting shaft 2221 is wrapped within the second area 2132 and is covered by the outer end surface of the first limiting member 214, and the entire structure of the connecting plate 2223 is wrapped within the third area 2133 and is covered by the outer end surface of the second limiting member 215, so as to increase the wrapping range and improve the stability of the wrapping fixation. In addition, the outer surface of the base structure 11 is configured as a non-arc-shaped structure from its top to its bottom, wherein the mounting plate 112 is arranged parallel to the supporting structure 21, and the structural arrangement is compact. The base plate 111 is configured as a conical ring structure, and the radius gradually increases from its upper end to its lower end. During the rotation of the turntable unit 2, the various parts of the base unit 1 are evenly stressed, so that the structure is stable and strong and not easily damaged, ensuring the safety of children during sensory integration training.
