Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention is an invention of a sphere driving device using a sphere.
[0002]
[Prior art]
Conventionally, a sphere driving device using a sphere is a sphere driving device using means for rotating and rotating the sphere by pressing three to four pressing rollers other than the sphere against the driven sphere.
[0003]
In the case of the conventional sphere driving apparatus using a sphere as described above, in order to control the direction, the direction is changed by adjusting the rotation speed of the driving roller pressed against the sphere to be driven. I have.
[0004]
[Problems to be solved by the invention]
However, the control of the direction change of the sphere by the driving roller pressed against the sphere is extremely complicated, and at the same time, the driving energy of the driving pressure roller being driven cannot be sufficiently transmitted to the sphere, and the sphere is pressed against the sphere. The efficiency of transmitting the driving energy of the roller was poor.
[0005]
Further, when a conventional sphere driving device having a structure including three or four pressing rollers for pressing the sphere and the sphere as described above is used as a wheel, the structure supporting the sphere driving device is used as an auxiliary means. There is a problem that the structure becomes very complicated.
[0006]
Furthermore, the conventional sphere driving device has a structure in which a casing containing a sphere which is a freely rotatable rotator is provided to control the moving direction of the sphere, but the sphere itself remains disorderly. In addition, there is a disadvantage that the exercise characteristics are not sufficiently exhibited.
[0007]
Therefore, the sphere driving device according to the present invention has a new motility by directly controlling the sphere, and aims to realize a sphere driving device that is extremely simple in structure.
[0008]
That is, it can be installed on any surface of the sphere without being limited to the equatorial portion of the sphere, and by driving a plurality of driving drum-shaped tops against the sphere, the sphere is driven, and a plurality of lines are drawn on a line passing through the center of the sphere. An object of the present invention is to provide a spherical driving device which is structurally extremely simple since the direction of the entire device can be surely changed only by rotating the shaft at the position where the center of gravity of the individual drum-shaped top is matched.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present invention has a sphere, two left and right drum tops pressed against the upper part of the sphere, and a shaft supporting the left and right drum top and attached with a spring.

As shown in FIG. 5, the left and right drum-shaped tops 3 and 4 are attached so as to be pressed against the upper part of the sphere.
[0024]
When the left and right drum tops 3 and 4 are brought into contact with the upper portion of the sphere 2, the contact angle α1 between the left and right drum tops 3 and 4 can be increased or decreased. By widening the contact angle α1, the positions of the left drum top 3 and the right drum top 4 become closer to the movement axis of the sphere 2. In this way, the support points at which the left and right drum tops 3 and 4 support the sphere 2 can be changed.

By changing the material, the rotational force of the left and right drum tops 3 and 4 can be reliably transmitted to the sphere 2. Further, the friction between the sphere 2 and the left and right drum-shaped tops 3 and 4 can be reduced to cause a slip.
[0029]
As shown in FIGS. 5, 6 and 7, by rotating the left and right drum-shaped tops 3 and 4 pressed against the sphere 2 simultaneously in the same direction in the rotation axis direction of the sphere 2, the frictional force with the sphere 2 is obtained. The sphere 2 can be rotated via.
[0030]
The rotation axes of the left and right drum-shaped tops 3 and 4 in pressure contact with the sphere 2 are arranged in the same direction as the rotation axis of the sphere 2 and at the same angle toward the center line of the sphere 2.

【The invention's effect】
Since the present invention has the configuration as described above, the following effects can be obtained. First, the sphere driving device according to the present invention can be installed on any surface of a sphere without being limited to the equator portion of the sphere in order to drive the drum-shaped top by pressing it against the sphere.
[0080]
Second, by holding a plurality of drum-shaped tops in contact with each other, the holding of the sphere is stabilized, and the direction can be reliably changed only by rotating the center of gravity of the plurality of drum-shaped tops on a line passing through the center of the sphere. Therefore, the structure is extremely simplified.
Furthermore, since the drum-type top can take more frictional surfaces with the sphere than before, the energy transfer efficiency is improved, and the holding of the sphere is stabilized by separating the drum-type top on a concentric circle from the center of the sphere. The frictional force with the sphere can be adjusted by increasing or decreasing the width of the top.
[0081]
Third, versatility can be added to the mechanism, for example, a mechanism for cushioning a shock such as a spring can be provided on the rotation axis of the direction control, and the present invention is advantageous in various situations such as a vehicle body, a transport device, and a playground equipment. It is possible to use it.
