Description

  The present invention relates to a rotating body that uses an elastic body as power.

  Background Art Toys that run by rotating a wheel using an elastic body such as rubber or a spring as power are widely known.

JP 09-313745 A

However, the conventional one has a main body and a wheel, and has a configuration in which an elastic body fixed to the main body is twisted and the wheel is rotated by using the return as power, and thus a non-rotating main body is essential. For this reason, the main body itself cannot be used as a rotating body, resulting in a complicated structure and a high device cost.
The present invention aims to solve the above-mentioned problems of the prior art.

In order to achieve the above object, a rotating body powered by an elastic body of the present invention includes a rotating body, an elastic body fixed at both ends so as to be rotatable together with the rotating body, and the elastic body. A weight that is fixed, and the weight locks the rotation of the elastic body, thereby causing twisting of the elastic body.
With the above configuration, the elastic body is twisted by rotating the rotating body, and when the twist returns, a rotational force is applied to the rotating body by reaction.
Here, the elastic body refers to a material having a property of returning from a twisted state, and rubber, a spring, and the like are typical examples. Further, synthetic resins and fibers can be used as long as they have a property of returning from a twisted state.
As the rotating body, a cylindrical body is generally used, and it is desirable that both ends of the elastic body are fixed to both end faces of the cylindrical body. Moreover, it is desirable to form the said cylindrical body from the soft material which maintains a cylindrical body shape by being filled with air. When such an air-filled rotating body is used, it is possible to increase the twisting return force of the elastic body by the elasticity of the rotating body itself.
The elastic body is preferably a string-like body made of a rubber material, but other elastic bodies can also be used.
The rotating body may be configured by a pair of rotating pieces and a connecting body that connects the rotating pieces, and an elastic body may be provided between the pair of rotating pieces.

  Since the rotating body powered by the elastic body of the present invention can cause twisting of the elastic body in the rotating body, a non-rotating main body is not required, and the main body itself can be a rotating body. There is an effect that the structure can be simplified and the cost of the apparatus can be reduced.

  Embodiments of the present invention will be described below with reference to the drawings.

  In FIG. 1, the rotating body 1 has a cylindrical shape having a side surface 10 and end surfaces 11 and 11. The rotating body 1 is made of a soft synthetic resin material, and has a structure that maintains a cylindrical shape by filling the air from the air inlet 19.

A pair of elastic bodies 2, 2 are provided inside the rotating body 1, and the rotating body 1 is configured to be rotatable using the elastic bodies 2, 2 as power.
The elastic bodies 2 and 2 use rubber strings in this embodiment.

The elastic bodies 2 and 2 are V-shaped as shown in the drawing, and one end side is fixed to the support plate 12 at fixing points 20 and 20, and the other end is fixed to the weight 3 at a fixing point 21.
The support plate 12 is a plate-like rigid body mounted on the inner side of the end surface 11, and fixedly supports two ends of the V-shaped elastic body 2 at fixed points 20 and 20.

The weight 3 is positioned substantially at the center in the axial direction of the rotating body 1, and both ends thereof are fixedly connected to the elastic bodies 2, 2 at fixed points 21, 21 and supported by the elastic bodies 2, 2.
Various weights 3 can be used, but in this embodiment, a plurality of super balls 31 are put in a bag 30 to be weighted.
The weight 3 has a weight that does not rotate due to the twisting of the elastic bodies 2 and 2, and the elastic bodies 2 and 2 can be wound by the weight of the weight 3.

In the above configuration, when the rotating body 1 is placed on a plane and the rotating body 1 is rolled in the direction of arrow B in FIG. 1, the rotating body 1 travels while rotating in the direction of arrow BR.
By this rotation, the elastic bodies 2 and 2 rotate, but the weight 3 does not rotate due to gravity. Therefore, the elastic bodies 2 and 2 are fixed at the fixing points 21 and 21, and the fixing points 20 and 20 are rotated, whereby the elastic bodies 2 and 2 are twisted.

FIG. 2 shows a state in which the elastic bodies 2 and 2 are twisted.
In this state, when the rolling body 1 stops rolling in the direction of arrow B and is released, the twisted elastic bodies 2 and 2 try to return to their original state, and the reaction causes the rotating body 1 to rotate in the direction of arrow FR. And run in the direction of arrow F.

As described above, the rotating body 1 can be rotated and traveled by the rotating body 1 itself, and does not require a non-rotating main body.
In the above embodiment, since the rotating body 1 is made of a soft synthetic resin material filled with air, the rotating body 1 itself has elasticity, and the end surfaces 11 and 2 are twisted by the elastic bodies 2 and 2. 11 are pulled toward each other. When the twisting of the elastic bodies 2 and 2 returns, the pulled end faces 11 and 11 also try to return to the original state, and this force is also applied to increase the returning force of the elastic bodies 2 and 2. In addition, when the elasticity of the rotating body 1 itself is sufficiently large, it is possible to adopt a normal string made of fibers or the like as the elastic bodies 2 and 2.
The rotating body 1 can be used as a toy that runs on a flat surface, and can also be used as a toy or a monument that simply rotates the rotating body 1 by pivotally supporting the center of the end surfaces 11 and 11. It is.
Moreover, it is also possible to use the rotary body 1 as a wheel of a traveling body, and it is not necessary to attach a power unit to the traveling body side, and a traveling body capable of traveling easily can be configured.

FIG. 3 shows another embodiment. In this embodiment, two elastic bodies 2ab are used, and the diaphragms 25 and 25 are passed through the elastic body 2ab. The weight 3 ′ is fixed to one elastic body 2b and is not fixed to the other elastic body 2a.
In the above configuration, if the rotating body 1 is rotated in the same manner as in FIG. 1, the elastic body 2a is locked to the weight 3 ', and the diaphragm rings 25 and 25 become the fixing points 21' and 21 '. The elastic body 2ab between the ring 25 and the fixed point 20 is twisted, and the rotating body 1 is rotated by returning the twist as in the configuration shown in FIG.

FIG. 4 shows still another embodiment.
In this embodiment, the rotating body 1 ″ is composed of a pair of circular end faces 11 ″ and 11 ″ and support members 15 and 15 connecting the end faces 11 ″ and 11 ″. 1 does not have the side face 10 as shown in FIG. 1, and only the end face 11 ″ is grounded and functions as a wheel. The end faces 11 ″ and 11 ″ may be discs or spokes. Various things, such as a wheel-shaped thing provided with, can be adopted.
The elastic body 2 ″ is also composed of a single rubber cord, and both ends are fixed at fixing points 20 ″ and 20 ″ positioned at the centers of the end faces 11 ″ and 11 ″. The weight 3 ″ is also elastic. It is fixed at a fixed point 21 ″ at a substantially central part of the body 2 ″.

In the above configuration, when the end faces 11 '' and 11 '' are rotated, the elastic body 2 '' is also rotated accordingly, but the elastic body 2 '' is twisted at the fixing point 21 '' by the weight 3 '' fixed to the central portion. . That is, when the elastic body 2 ″ is twisted between the one fixing point 20 ″ and the fixing point 21 ″ and between the other fixing point 20 ″ and the fixing point 21 ″, the twist is restored. It becomes rotational power and rotates the end faces 11 ", 11".
The configuration of FIG. 4 is suitable for being used for a wheel of a traveling body.
