Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is an improvement of the steering device, specifically, it requires a surprisingly small space compared to conventional steering devices and is extremely safe to use. The present invention relates to a stationary manipulator that can be used.

[Prior art and problems to be improved] A device that has a cylindrical frame as a whole, and in which the frame rolls on the ground like a wheel when the trainee moves the center of gravity inside the frame, It has traditionally been used as a manipulator because it is effective for physical training and strengthening the sense of balance.

However, conventional controllers that are designed to roll on the ground have the following inconveniences.

■ It is difficult to find a flat and spacious practice area.

■ Because there is no steering mechanism for braking or direction control, collisions and personal accidents are likely to occur.

■ In addition to the centrifugal force, there is also the movement inertia of the controller itself, making high-speed rotation practice practically impossible.

The present invention aims to eliminate the inconveniences of conventional manipulators as listed in items 1 to 3 above, and to go one step further to improve the manipulator so that it can be used by anyone on a daily basis as a physical training tool. This is a technical issue.

[Means Adopted to Solve the Technical Problems] The means adopted by the present inventor to solve the above-mentioned technical problems are explained below based on the attached drawings.

That is, the present invention is a cylindrical member which has a pivot shaft 1 supported by a thrust bearing 41 on a base frame 4 on one side, and the other side is open so that the trainee T can enter from there. The turn wheel 2 rotates in any direction, forward or backward, as the center of gravity P of the body moves due to the movement of the trainee T.
and a band rail 3 disposed in the internal space of the turnwheel 2, which itself is configured in a concentric or spiral shape so as to surround the rotational axis R-R of the turnwheel. The present invention provides a stationary controller with a built-in design.

〔Example〕

Hereinafter, the present invention will be explained in more detail based on illustrated embodiments.

In the steering device shown in FIGS. 1 to 4, a cylindrical member is employed as the turnwheel 2. As shown in FIG.

The turnwheel 2 shown in the figure is made from a small amount of metal and synthetic resin materials in order to reduce rotational inertia, and its size is usually about 200 cm in diameter and about 75 cm in depth so that it can be accessed by adult trainees. Designed from front to back.

However, if it is intended for children only, the diameter should be approximately 100a.
++ By designing the front and back, children can play inside the turnwheel 2 like a spinning top and mouse, improving playability, and the cylindrical body circumference acts as a guard wall, improving safety. It also increases.

The turnwheel 2 has an end plate 21 in the illustrated example, and the pivot 1 is attached to the center of the end plate 21 (see FIG. 2). It is supported by a thrust bearing 41, and is rotatable in forward and reverse directions together with the turnwheel 2 about a rotational axis RR that is balanced on the installation surface.

The band rail 3 is a member provided to stably support the hands and feet of the trainee T when training with the manipulator of the present invention. By doing,
The turn wheel 2 can be rotated arbitrarily in forward or reverse directions.

In the illustrated example, the band rail 3 is attached concentrically to the inner surface of the end plate 21, but it may be arranged in a spiral manner.

In this case, it is preferable to take into account the height deviation of the band rail 3 and set the pitch so that it will fit as many people as possible and will not interfere with use.

Furthermore, in the manipulator of the present invention shown in FIGS. 1 and 4, the diameter of the band rail 3 becomes smaller as the distance from the rotation axis R-R becomes smaller. Although it is configured to be located deep inside the turnwheel 2 (on the end plate 21 side), when a trainee with a large height and 4-stage size uses this controller, the band rail 3 of the small diameter part The phase is shifted so that it does not get in the way.

Although the steering device of the present invention is generally constructed as described above, the present invention is by no means limited to the illustrated embodiment, and various modifications can be made within the scope of the claims. Therefore, for example, it is possible to configure the overall shape of the turn wheel 2 into a polygonal cylinder shape, or to configure the band rail 3 into short lengths and arrange them in a concentric or spiral manner as appropriate depending on the requirements of product planning. This is a matter to be scheduled.

[How to use the operating device of the embodiment and its function] The operating device of the embodiment having the above structure allows the trainee T holding onto the band rail 3 to move on his/her own as shown in Fig. 5 A to E. If the centrifugal force is skillfully amplified by moving the center of gravity P of the robot, it will be possible to rotate the robot in any direction, forward or reverse, much more smoothly and at a higher speed than with conventional manipulators. In addition, since a cylindrical member is used as the wheel 2, even if the sheet metal or trainee is accidentally thrown off the bundle rail 3 during training, the circumference of the turnwheel 2 will act as a guard wall. It is extremely safe to avoid being ejected to the outside, and at the same time, the rotation of the turnwheel 2 is suddenly stopped.

[Effects of this invention]

In this way, the inventive manipulator does not require any large space unlike conventional manipulators, and allows physical training and balance training to be carried out easily even in a normal room. It is extremely safe, as training can be done within a certain partitioned space without rolling, so there is no risk of collision or personal injury like with conventional controllers.
