And a playgame member is fixed to the rotating plate of the rotary device, and the playgame member rotates together with the rotating plate, by eccentric rotation.
In accordance with an aspect of the present invention, when the rotating shaft rotates by the drive motor, the rotating plate will make eccentric rotation (rotating around the position within the specified distance from the center of the rotating plate), by fixing the rotating plate to the rotating shaft of the drive motor via the crank. And, the rotating plate makes the movement that a user does not expect by rotating around the position secured by the crank. The playgame member fixed to the rotary device is preferable in any configuration, and any playgame member can make eccentric rotation and can make further complicated movement. When a slanted rotating plate is used, the distances from the undersurface of the rotating plate to a floor are different, and thus it is preferable to fix a wheel to the rotating plate undersurface via an adjustment member to equate the height to a floor. The height of adjustment member is determined depending on the position where a wheel is placed.
In accordance with an aspect of the present invention, the crank may comprise a support horizontally supporting the rotating plate, and a fixture pivotally supporting the support to the rotating shaft. The rotating plate may be inclined against a horizontal-plane by being pivotally supported to the rotating shaft.

DESCRIPTION OF THE PREFERRED EMBODIMENT
Detailed Description of the Preferred Embodiment 1
A specified embodiment of a rotary device 100 for rotating a rotating amusement apparatus 200 of this Invention is explained hereinafter with reference to the accompanying drawings. FIG. 1 is a schematic view of a rotary device 100 of this Invention. However, the details of parts which do not directly-relate to the present invention will be omitted. A playground equipment making eccentric rotation around a specified rotating shaft can be configured by associating the rotary device 100 of this Invention with a desired playground equipment (hereinafter a structure attached to the rotary device 100 is referred to as playgame member 210).
As shown in FIG. 1 (A), the rotary device 100 of this Invention is provided with a drive motor 111 as a driving means, and with a shaft shifting means (e.g., crank 112) comprising a handle connected to a rotating shaft, connecting another shaft shifted to a prescribed distance from the rotating shaft. At first, a drive motor 111 is placed on a base 110 (if a motor 111 and an after-mentioned elastic body are placeable, any shaped is preferable). The shaft shifting means (crank 112) is attached to the rotating shaft of the drive motor 111, and the rotating shaft of the drive motor is displaced within a specified range.
One end of the crank 112 rotates on a shaft same as the rotating shaft of the drive motor 111, and the other end of crank 112 makes eccentric rotation around the rotating shaft. Of course, a switch (not shown) for operating the drive motor 111 is provided to the rotary device 100. A rotating speed of the drive motor 111 may be configured to be controllable by the switch.
Also an overload protection means (e.g., torque limiter), not illustrated, for protecting the over load of the drive motor 111 may be attached to the rotating shaft of the drive motor 111, or to the crank 112.
The playgame member 210 imitating yachts is placed on the upper part of the drive motor 111 as will hereinafter be described. Therefore the weight of a user expecting to play with the rotating amusement apparatus 200 of this Invention is added to the drive motor 111. If the load added to the drive motor 111 is greater than a predetermined value, the overload protection means detects the load, and idles the drive motor 111. Then, a rotating plate 115 (described below) fixed by the crank terminates the autorotation of drive motor 111. The playgame member can be moved rotatable (hand-operated rotation) to the user's desired direction.
As described above, one end of the crank 112 is attached to the rotating shaft of the drive motor 111. The rotating plate 115 is attached to the other end of the crank 112. The rotating plate 115 with any shape is used if the playgame member 210 can be attached, and a rotating plate 115 having many kinds of shapes such as rectangular, polygon, circle or the like, can be attached. As in the preferred embodiment (cf. FIG. 1 (B)), the rotating plate 115 with a similar configuration of the base (described below) of the playgame member 210 attached to rotary device 100 can be used.
As shown in FIG. 2, a playgame base 211 is fixed to the upper part of the rotating plate 115 as the base of playgame member 210. In the present embodiment, it is fixed by bolts 221 and nuts 222. The rotation of the crank by the motor causes the rotation of the playgame base by fixing the playgame base 211 to the rotating plate 115.
Wheels 130 are put on the lower part of the rotating plate 115. The wheels 130 are put on symmetrically with each other in top-view. In the present embodiment, as shown in FIG. 1 (B), one pair of wheels is put on before and behind the rotating plate 115 and two pairs of wheels are put on both sides of the rotating plate 115, so that six wheels are put on the rotating plate 115. A height adjusting means 131 for adjusting the height of a wheel 130 may be further provided. The rotating plate 115 makes eccentric rotation around via the crank 112 which was attached to the rotating shaft of the drive motor 111 when drive motor 111 operates (it is meant that it rotates in the conditions where rotating shaft slipped off). When the drive motor 111 operates, the rotating plate 115 makes eccentric rotation via the crank 112 attached to the rotating shaft of the drive motor 111 (mean rotating with rotating shaft displaced within a specified range). At this time, the rotating plate 115 rotates while rotating on the rotating shaft of the drive motor 111. The rotating velocity of this rotating plate 115 is not constant, and thus the rotating plate 115 rotates in an unexpected velocity. Therefore, as will hereinafter be described, when the playgame member 210 is fixed to the rotating plate 115, the playgame member 210 works to a user unexpectedly.
A specified shock absorber is coated to the rotating amusement apparatus 200 of the present invention. A foam such as urethane is coated to the outer frame of the rotating amusement apparatus 200 as this shock absorber. For example, the one side face of the shock absorber of a hollow cylinder is cut, so as to be coatable on the stick face. And the shock absorber having been coated on a part of the rotating amusement apparatus 200 (even all surfaces of the apparatus is preferable and may be the part that it is expected that a user comes in contact with), and, a gum resin having been painted on the surface of the shock absorber, as a result of that a surface of the shock absorber has a water repellency. Of course the side (cut part) of the shock absorber will be closed when gum resin is painted. The shock absorber may be a composition other than urethane, and shock absorber like foams such as polyethylene is preferably used.
A regulation means 140 for regulating the auto-rotation of the rotating plate 115 can be provided. An elastic body (rubber or a spring are preferably used) connecting between the base 110 supporting the drive motor 111 and the rotating plate 115 is used as the regulation means 140. If the regulation means 140 can be configured to regulate auto-rotation of the rotating plate 115, any alignment method thereof is preferable. In accordance with exemplary embodiments, as shown in FIG. 1 (C), the regulation means 140 is placed slopewise from near the end of base 110 to the undersurface of the rotating plate 115. As another configuration, the regulation means 140 is orthogonally-placed from near the end of the base 110 to the undersurface of the rotating plate 115 perpendicular to end of base 110.
If the regulation means 140 can be configured to regulate auto-rotation of the rotating plate 115, any shape for the regulation means 140 is preferable. In accordance with exemplary embodiments, a pair of belt-shaped or stick-shaped rubber is formed and is placed to the position as described above.
The auto-rotation of the rotating plate 115 is regulated by composing the regulation means 140 such as rubber, and thus the rotating plate 115 swings while rotating on the rotating shaft of the drive motor 111.
As another configuration of the regulation means 140, one end of rubber formed into a cylinder-shaped or truncated cone is connected to the base 110 and can connect the other end of the rubber to the above rotating plate 121. As shown in FIG. 2, a soleplate (corresponding to the playgame base 211) of the playgame member 210 imitating yachts is fixed to the rotating plate 115 of the rotary device 100 configured as above. In the present embodiment, the rotating plate 115 and playgame base 211 are fixed using well-known bolts 221 and nuts 222. In the case of playgame member 210 (e.g., playgame member 210 imitating a yacht and windsurfing of FIG. 2) comprising strut 212, it is desirable a rib 225 is provided on the lower part of the strut 212, for assisting the strut 212.
As for the playgame member 210 fixed to the rotary device 100 of the present invention, any shape is preferable. All playgame members 210 such as a jungle gym, the tree (a playground equipment imitating a tree and configured to be able to climb the tree) can be turned with the rotary device 100 besides a yacht and a surfing.
Detailed Description of the Preferred Embodiment 2
As noted in the detailed description of the preferred embodiment 1, a rotating plate 115 is attached to one end of the crank 112 (the other end is attached to rotating shaft of drive motor 111). In contrast, in preferred embodiment 2, the rotating plate 115 will be attached to one end of the crank 112, with the rotating plate 115 inclined.
As shown in FIG. 3 (A), a support 112a enabling the rotating plate to be horizontally supported is formed. If the rotating plate 115 can be horizontally supported to the upper part or side of the support 112a, any shape is preferable. For example, the support 112a can be shaped as a column, a square pole, or a triangle pole. In the present embodiment, the rotating plate 115 is horizontally put on a top of the support 112a formed cylindrically.
The support 112a with a part putting the rotating plate 115 inclined against a horizontal-plane is fixed to the rotating shaft of the drive motor 111. In the present embodiment, the support 112a is fixed to the rotating shaft of the drive motor 111 via a fixture 112b attached on the side of the support 112a, for fixing the inclined support 112a. 
The support 112a and the fixture 112b correspond to the crank 112 of the preferred embodiment 1. In supporting the rotating plate 115 at the sides of the support 112a, the support 112a is fixed to the rotating shaft of the drive motor 111 while the sides of the support are inclined against a horizontal-plane. Also wheels 130 described in the detailed description of the preferred embodiment 1 may be put on lower part of the rotating plate 115. In this embodiment, the rotating plate 115 is inclined against a horizontal-plane, thus the height from the lower parts of the rotating plate 115 to a floor may be varied according to a position of the rotating plate 115. Therefore, it is desirable that the height from the under surface of the rotating plate 115 to the wheel 130 is adjusted by attaching the wheel 130 to the rotating plate 115 via a height adjusting means 131 of the detailed description of the preferred embodiment 1. In the case of the present embodiment, a regulation means 140 for regulating the auto-rotation of the rotating plate 115 may be provided.
Also by applying a gum resin to the surface of a shock absorber coating an exterior frame of the rotating amusement apparatus 200, the shock absorber having a water repellency on its surface can coat the exterior frame.
Detailed Description of the Preferred Embodiment 3
In the preferred embodiment 1, the playgame base 211 (soleplate) of the playgame member 120 is fixed to the rotating plate 115. In contrast, the rotating plate 115 can be hung from an upper part.
As shown in FIG. 4 (A), inverted “U-shaped” frame 230 is continuously integrally formed. Of course, the frame 230 may be formed by combining a plurality of frames. Then the frame 230 is vertically arranged to both ends of the base 110 (the base 110 supporting a motor) extending forward and backward. One end of a hung member such as the wire is connected to a symmetric position of the upper part of the frame 230, and the other end is connected to the rotating plate 115 under the frame. That is to say, the rotating plate 115 is connected to the base 110 via the drive motor 111 and the crank 112, and is hung from the upper part by the hung member 235.
The hung member 235 can hang the rotating plate 115 as follows. As shown in FIG. 4 (B), a pair of frames 230 is vertically arranged to an edge of the base 110 so as to intersect each other. And, hung members 235 can be connected to symmetric positions to each other, along a periphery of a ring 240 placed above the frame 230. The other end of the hung members 235 are connected to the rotating plate 115.
A drive motor 111 described in the detailed description of the preferred embodiment 1 is placed under the rotating plate 115. Crank 112 is attached to the rotating shaft of the drive motor 111, and the rotating plate 115 is fixed to the other end of the crank 112. Also the base 110 and the rotating plate 115 may be connected by the regulation means 140 described in the detailed description of the preferred embodiment 1. In this embodiment, wheels are not necessary.
When the rotating shaft of the drive motor 111 rotates by operation of the drive motor 111, the crank 112 makes eccentric rotation. Also in the present embodiment, the rotating plate 115 connected to the wire rotates when the wire hung by member 235 is swung by a user.
Also by applying a gum resin to the surface of a shock absorber coating an exterior frame of the rotating amusement apparatus 200, the shock absorber having water repellency on its surface can coat the exterior frame. Another configuration of playgame member 210 is shown in FIG. 5. The playgame member 210 is provided with a strut 212 (corresponding to a support base) vertically arranged on a playgame base 211, and with a holding member 522 (the members having a shape enabling a user to hold) hung from the upper end of the strut 212 via a support arm 520.
In the present embodiment, when a motor (different from the drive motor 111 provided to the rotary device 100) provided to a hollow portion of the strut 212 formed using a hollow pipe rotates, the strut 212 rotates. Also each end of a plural of the support arms 520 is connected on the top surface of the strut 212. Each support arm 520 is radially arranged at equal intervals in the circumferential direction from a center axis of the strut 212. A position near one end of each support arm 520 is bundled by a fixing member 523.
The holding members 522 connected to the support arms 520 are placed at specified intervals from the outer peripheral surface of the strut 212. And when the strut 212 rotates (meaning a rotation by operation of the motor in the strut 212), the holding members 522 rotate. For example, holding members 522 are formed in a spherical shape, a ring, or a column shape, and a user can hold onto and hang on an outer peripheral surface of the holding member 522, and an annular inner peripheral surface of the holding member 522.
An air cushion may be placed in the perimeter of the strut 212. Even if a user falls off a holding member 522 by mistake, the air cushion reduce the user's impact, and a user's injures can be prevented effectively. The air cushion can be configured from a seat member having a flexibility. When the air cushion swells as a result of charging of the air by blowers, a hemispherical portion is formed in the center part, and three different-sized annular sections may be formed therearound. A playgame base 211 of the playgame member 210 is placed on the top surface of the rotating plate 115 of the rotary device 100 while the outermost of the annular portion is protruded from the outside.
Another playgame member 210 is shown in FIG. 6. This rotating amusement apparatus 200 is configured to place the playgame member 210 imitating a balloon on the playgame base 211. A holding member 522 is hung from a balloon support base 610 for supporting a balloon body 630 placed on the top face of the playgame base 211 via ropes. The holding member 522 is placed in the center axis circumference of the balloon body 630, and turns by a rotation of rotating amusement apparatus 200.
If balloon body 630 can be supported, the balloon support base 610 can be any shape. However in the present embodiment, a plurality of struts 212 are placed at equal intervals in the circumferential direction from the playgame base 211 (as shown in FIG. 6, shape warping the upper portion of the strut 212 outward). Each strut 212 is fixed by a ring-shaped member 612. In FIG. 6, each strut 212 is fixed in three places of an upper portion, an intermediate portion, and a lower portion. The ring-shaped member 612 placed in the upper portion of the struts 212 supports directly the balloon body 630.
Another configuration of playgame member 210 is shown in FIG. 7. A frame 230 of an octagon shape is formed so that a plurality of rod members are vertically and horizontally combined. A partitioning member 710 is provided to the outside of the frame 230. The partitioning member 710 comprises a sheet having a flexibility, and is beamed between each member configuring the frame 230, and a decoration for attracting a user's attention (not shown) is ornamented to the outer surface thereof attracting a user's attention. In addition, an opening for communicating between the partitioning member 710 and the outside space and for enabling a user to go in and out may be formed.
A beam 720 is placed horizontally to the frame 230, and a floor member 730 is fixed between the adjacent beams. Each floor member 730 comprises a sheet member having a flexibility, and partitions a game region in upper and lower directions into three spaces. In addition, by providing a predetermined number of the communication portions vertically communicating adjoining spaces with each other, the top and middle spaces communicate with each other, and the middle and bottom spaces communicate with each other, so that a user can move within the playgame member 210.
The user can play like in a jungle gym, by moving laterally along the beam, moving laterally over the floor member 730, and moving vertically through the communication portion.
