Action toys

Abstract

To provide a motion toy that can swing its body up and down using a simple mechanism employing a planetary gear system. [Solution] An action toy comprising a motor capable of forward and reverse rotation, wheels, and a drive device that transmits the power of the motor to the wheels and rotates the wheels in accordance with the forward and reverse rotation of the motor, wherein the toy body is provided with a rocking body that swings around a first axis extending in the width direction and extends in and out of the toy body by the swinging, the rocking body is provided with wheels at a position away from the first axis, the drive device includes a planetary gear mechanism with the rocking body as arms, the first axis is provided with a sun gear, the rocking body is provided with planetary gears linked to the wheels, furthermore the first axis is provided with a first surface that is perpendicular to the first axis and rotates integrally with the sun gear, and the rocking body is provided with a second surface that faces the first surface, contacts the first surface and operates by the frictional force generated between the first surface and the first surface.

Claims

1. A motion toy comprising a motor capable of forward and reverse rotation, wheels, and a drive device that transmits power from the motor to the wheels and rotates the wheels in accordance with the forward and reverse rotation of the motor, The toy body is provided with a swinging body that swings around a first axis extending in the width direction, and that extends and retracts relative to the toy body as a result of the swinging motion. The oscillating body is provided with the wheels at a position away from the first axis, The drive device includes a planetary gear mechanism in which the oscillating body is used as a planetary carrier. The first shaft is provided with a sun gear that constitutes the planetary gear mechanism. The rocking body is provided with planetary gears that constitute the planetary gear mechanism and are linked to the wheels. Furthermore, the first axis is provided with a first surface that is perpendicular to the first axis and rotates integrally with the sun gear, The oscillating body is provided with a second surface that faces the first surface, contacts the first surface, and operates due to the frictional force generated between the first surface and the oscillating body.

2. The action toy according to claim 1, wherein an elastic body is provided between the toy body and the oscillating body, biasing the oscillating body in a direction that causes it to protrude from the toy body, and the oscillating body, under normal conditions, is retracted into the toy body against the biasing force due to the weight of the toy body.

3. The action toy according to claim 2, characterized in that the planetary gear and the wheel are linked via a gear provided on the axle.

4. The elastic body is characterized in that it is a torsion spring wound around the first shaft and placed between the toy body and the oscillating body. The action toy according to claim 2 or claim 3.

5. The action toy according to claim 2 or 3, characterized in that the first surface and the second surface are flat.
