Abstract

PURPOSE:To provide a roller skate having a driving means and a control means, bath of which can be easily handled by a wearer. CONSTITUTION:A driving wheel 14 provided on a glider part 1 is driven by torque transmitted from a d.c. motor 36 included in a driving circuit 10, through a power-transmitting wheel 13. A transfer switch 34 included in a driving circuit 10 can be transferred by a forward movement-handling push button and a stop- handling push button which are provided on a remote control device and by a control-handling push button SW1 provided on the glider part 1. When the forward movement-handling push button is pushed, the d.c. motor 36 included in the driving circuit 10 transmits driving power for driving the slider part 1 forward to the driving wheel 14. When the stop-handling push button is pushed, the transfer switch 34 is held in neutral. When the control-handling push button SW1 is pushed, the d.c. motor 36 included in the driving circuit 10 is driven reversely, and thus in the condition that the glider part 1 glides forward, the rotation of the driving wheel 14 is controlled and braked.

A drive circuit 10 is provided at one end of the base 2.
A battery 11 that supplies electromotive force to the drive circuit 10 is also provided. Rotational power from the drive circuit 10 is transmitted to the transmission wheels 13. The peripheral edge of the transmission wheel 13 and the peripheral edge of the drive wheel 14 are in close contact with each other, and the rotational power transmitted to the transmission wheel 13 is transmitted to the drive wheel 14 by frictional force.

The drive wheels 14 and 15 are attached to the rotary shaft 16 by nuts and the like, and are pivotally supported by the base 2 by bearings 17. The rotational power transmitted from the transmission wheel 13 is transmitted to the drive wheel 14 and also to the drive wheel 15 via the rotary shaft 16. Driven wheels 18, 19
Is attached to the rotary shaft 20 using a nut or the like, and is rotatably supported by the base 2 by a bearing 21.

The actuator 22 turns ON / OFF the braking means included in the drive circuit 10.

FIG. 3 is an enlarged sectional view showing the mounting structure of the actuator 22. The actuator 22 is attached to the control operation push button SW1 by a fulcrum 23. The spring force of the spring 24 mounted in the control operation push button SW1 causes the actuator 22 to move.
Has been rolled down. The protection member 25 is made of synthetic resin such as plastic and protects the control operation push button SW1.

By lowering the heel portion of the sliding portion 1 on the road surface, the actuator 22 comes into contact with the road surface. At that time, the actuator 22 is angularly displaced counterclockwise in FIG. 3 against the spring force of the spring 24, and the control operation push button SW1 is turned on.
N

When the control operation push button SW1 is turned on, the changeover switch for connecting the DC motor and the battery 11 included in the drive circuit 10 is switched so that the DC motor rotates in the reverse direction. As a result, in a state where the sliding portion 1 is sliding forward, the drive power of the drive wheels 1 is generated by the rotational power transmitted by the drive circuit 10.
4 rotation control is performed.
