BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to the field of toys, and more particularly to a self-propelled toy.
2. Description of Related Art
As can be seen by reference to the following U.S. Pat. Nos. 1,605,307; 1,762,574; 3,744,182 and 5,713,780 the prior art is replete with myriad and diverse self-propelled toys.
While all of the aforementioned prior art constructions are more than adequate for the basic purpose and function for which they have been specifically designed, they are uniformly deficient with respect to their failure to provide a simple, efficient, and practical self-propelled toy.
As a consequence of the foregoing situation, there has existed a longstanding need for a new and improved self-propelled toy and the provision of such a construction is a stated objective of the present invention.
BRIEF SUMMARY OF THE INVENTION
Briefly stated, the present invention provides a self-propelled toy including a body member in the shape of an animal such as a gorilla. The body member includes a torso with a pair of legs and a pair of rotatably attached arms that are slightly longer than the legs when rotated to their lowermost position. A rotary drive, such as a battery powered DC motor or a wound spring drive, is operably attached to the body member with its output drivably coupled to the arms. The arms rotate 360° with respect to the torso in synchronization with each other. Pivotally connected hand and feet portions provide a degree of freedom for better landing and balance. As the arms rotate, the hands contact the floor to raise the body member and move it a step forward. Each complete revolution of the arms advances the toy another step forward.
