Abstract

Problems are solved in a conventional traveling structure that can perform only the back and forth movement, circularly back and forth movement, and straight laterally movement, so that every directional movement is desired, and is not suitable for a traveling structure of agricultural equipment desired to be movable in every direction, and also is not enough of a challenge to be a traveling toy. In a traveling structure for traveling by rotating wheels with a driving source such as a motor, the traveling structure comprises a main body, the wheels arranged on every side of the main body, and auxiliary wheels arranged in the wheels rotatably in a direction perpendicular to the rotating direction of the wheels, wherein the auxiliary wheels are protruded from a supporting surface of the wheels.

Claims

1. A traveling structure for traveling by rotating wheels with a driving source such as a motor, the traveling structure comprising:

a main body;

the wheels arranged on every side of the main body; and

auxiliary wheels arranged in the wheels rotatably in a direction perpendicular to the rotating direction of the wheels,

wherein the auxiliary wheels are protruded from a supporting surface of the wheels.

3. A structure according to claim 1 or 2, wherein the wheels are attached to ends of legs extended from four sides of the main body.

4. A structure according to claim 3, wherein at least one pair of the legs comprise two legs.

5. A structure according to claim 3 or 4, further comprising;

a drive member attached to an end of each of the legs; and

a reducer gear train accommodated in the driving member,

wherein the driving source is accommodated in the drive member, and

wherein a driving force is transmitted to each of the wheels via the reducer gear train.

6. A structure according to claim 3 or 4, further comprising a reducer gear train, wherein the driving source and the reducer gear train are accommodated in each of the legs and a driving force is transmitted to each of the wheels via the reducer gear train.

7. A structure according to claim 5, wherein the drive member comprises a fixing member attached to each of the legs and a movable member rotatably attached to the fixing member, and the driving source and the reducer gear train are accommodated in the movable member while a suspension is interposed between the fixing member and the movable member.

8. A structure according to claim 6, wherein each of the legs is longitudinally divided into two parts having a suspension interposed therebetween.

9. A structure according to claim 1 or 2, wherein the auxiliary wheels accommodated in each of the wheels are arranged in a single column in a circumferential direction.

10. A structure according to claim 1 or 2, wherein the auxiliary wheels accommodated in each of the wheels are arranged in a double column, in a staggered configuration, and in a circumferential direction.

11. A structure according to claim 1 or 2, wherein the structure is a radio-controlled traveling toy.

2. A traveling structure for traveling by rotating wheels with a driving source such as a motor, the traveling structure comprising:

a main body;

the wheels arranged on every side of the main body; and

auxiliary wheels arranged in the wheels rotatably in a direction perpendicular to the rotating direction of the wheels,

wherein the auxiliary wheels are protruded from a supporting surface of the wheels, and

wherein a suspension effect of absorbing unevenness on a traveling road is imparted to the wheels.
