Traveling structure
First Claim
1. A traveling structure comprising:
- a main body;
a crosswise pair of legs attached to said main body;
a plurality of traveling wheels rotatably mounted to respective ends of said legs so that the wheels are arranged on every side of the main body for supporting the main body to allow for rolling movement along a traveling surface; and
a plurality of driving sources each being operatively coupled to a respective one of said traveling wheels for independently driving each of said traveling wheels to thereby cause the main body to be propelled along a surface;
wherein each of said traveling wheels has a circumferential supporting surface, and includes a plurality of auxiliary disc-shaped wheels freely rotatably mounted to respective ones of said traveling wheels in circumferential spaced-apart relationship relative to the supporting surface of the traveling wheels so that a portion of each said disc-shaped wheel protrudes from a said supporting surface and engages the traveling surface along which the main body travels.

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.
