The present invention relate to a playground equipment driving motor-placement device as for for and rotating playground equipment, and in particular, it relates to a rotating playground equipment allowing users to hold and play.
The rotatable playground equipment which a user (mean infants and young children) can hang from it attract users, also the demand as the amusement apparatus is high. For example, following patent document 1 discloses the rotation playground equipment capable of entertaining infants and children seated or hung from it.
Japanese Unexamined Pat. Application. Publication. No. H10-113474
The rotary playground equipment described in the above patent document rotates, by the shifting of user's weights in hanging the users. However, the rotary playground equipment of the disclosure in the patent document does not rotate when no users seat. When the rotary playground equipment does not rotate, it cannot be distinguished from normal chairs, thus it is difficult to make users think that they want to a game such as a sitting and holding game, with the rotary playground equipment.
On the other hand, the infants and the little users are easily interested to the moving things. Therefore, if rotary playground equipments rotate by a drive motor automatically, it can make the lasted interest of the user, so the playground equipment maker had the demand for a rotatable playground equipment with a drive motor. However, depending on the position of the drive motor (mean that a drive motor occupies most of the space), it would be disadvantageous for maintenances, so many playground equipment meters didn't want the rotating playground equipments comprising the drive motor provided.
Furthermore, drive motors are often placed in the position that is not visible from external (e.g., the inside of the strut). For example, when a drive motor is placed in the strut, the heat of the drive motor is hard to be emitted to external of the strut, the temperature of the drive motor rises, and the rotation of the motor thereby stops. Therefore, because the drive motor frequently stops caused by the heat, the playground equipments makers didn't want to attaching a drive motor to the rotating playground equipments. Security does not have a problem, even if the temperature of the drive motor rises, the drive motor only stops. An object of the present invention is to provide a playground equipment driving motor-placement device and a rotating playground equipment which is rotatable by a drive motor and is easy maintenance.
The present invention to solve above problems is a playground equipment driving motor-placement device provided with a lower stationary component and an upper rotator. The lower stationary component comprises a stationary plate removable to a playground equipment and a lower stationary component having a shaft vertically arranged by the stationary plate. And, the upper rotator is configured to be able to rotate around the shaft of said lower stationary component, and is provided with a handle support that supports handles that users can grasp, and a driving motor support that supports the driving motor; the driving motor support is provided above the handle support. And, a coupling is fixed to the upper portion of a shaft, for conveying the rotation of the drive motor to a shaft of the lower stationary component.
By above configuration, the upper rotator is rotatable against lower stationary, a drive motor is placeable to upper part of the driving motor support of the upper rotator. And a coupling is fixed to the upper portion of a shaft, for conveying the rotation of the drive motor to a shaft of the lower stationary component. Thus the playground equipment placing a drive motor to the upper part and rotating the whole apparatus, can be easily configured by using the playground equipment driving motor-placement device of the present invention.
In accordance with an aspect of the present invention, a torque limiter provided on the upper rotator, for controlling a driving torque of a rotating axis of the drive motor within predetermined value can be provided. Alternatively, a inverter provided on the upper rotator, for stopping the supply to the drive motor, when currents more than or equal to predetermine. Furthermore, slip ring for supplying electric power to the playground equipment driving motor-placement device may be provided.

Furthermore, it can be effectively prevented that the lines such as power lines get twisted up because a slip ring which provided in the upper rotator rotates along with the upper rotator.
In accordance with an aspect of the present invention, the upper rotator may be configured to make eccentric rotation. For example, a through-hole is formed to the eccentrically placed position from the center of the upper rotator, and a shaft passes through the through-hole.

That is to say, vertically placed rod 510 is hung from the other end of each large size arm-shaped member 132 and small size arm-shaped member 132. For example, the vertically placed rods 510 hung down the large size arm-shaped member 132 are fixed by a large ring 520, and furthermore the vertically placed rods 510 hung down the small size arm-shaped member 132 are fixed by a small ring 520, and thus the rotating playground equipment 100 of the jungle gym shape having a double ring can be configured as shown in
The ring 520 for fixing the vertically placed rod 510 hung down to the arm-shaped member 132 is not limited to circle-shaped ring 520, it may be form of oval and rectangle shape or the like as shown in
As shown in
Alternatively, as shown in
At this time, a connecting point of the supporting rod 810 is regulated so that the rectangular can place on the top surface of handle support 240. And, a circle-shaped handle 130 is formed by fixing the other end of each four supporting rod 810 into the ring 520. The handle formed in this way may be placed to the handle support 240. That is to say, the T-shaped supporting rod functions as a beam to the ring 520.
Then plurality of vertically placed rods 510 is hung from end of the ring 520. In this embodiment, the vertically placed rod 510 is hung so as to fix to end of the supporting rod 810 of opposite position. Furthermore, another ring 520 is fixed to ring 520 where the vertically placed rod 510 is fixed, at an angle, and the rotating playground equipment 100 may be configured by coupling the ring 520 by zigzag-shaped in total.

As mentioned above, the rotating playground equipment attaching the motor-placement device of the present invention is designed on the assumption that it hold and move the weight by a plurality of users. By above configuration, if the loads more than specified is added to the drive motor 210, the overload protection means detects the load, and idles the drive motor 210
Furthermore, torque sensor for detecting running torque may be comprised. As the torque sensor, a contact-type torque sensor may be used, alternatively a noncontact torque sensor may be used too. If a torque detected by the torque sensor is beyond an expected limit, the rotative power from the drive motor 210 is not transmitted to the shaft 260 of the lower stationary component. It is desirable for the torque limiter and the torque sensor to provide to the upper rotator 220 of the motor-placement device 200.
Alternatively, when excessive torque as described above is applied (i.e., when an excessive electric current is carried to the drive motor 210), the inverter which interrupts electric current to the drive motor 210 may be provided in substitution for the torque limiter and torque sensor. It is desirable for the inverter to provide to the upper rotator 220 of the motor-placement device 200.
