Abstract
A walking mechanism for a toy having two legs. Each leg is provided with a vertically elongated slot intermediate its ends which receives a pin connected to a frame mounting a drive motor. The drive motor operates a shaft bearing two eccentrics with the eccentrics being located 180.degree. apart about the shaft and each eccentric is drivingly connected to one end of a respective leg. As a result, each leg is driven through a generally elliptical path with the movement of each being 180.degree. out of phase with the movement of the other.
Claims4
A walking mechanism for a toy comprising:
- first and second legs, each having first and second opposite ends with a surface engaging portion at the first end thereof, a driving portion at the second end thereof and a portion of a pin and slot connection on each leg near the second end and intermediate the first end and the driving portion;
- a drive mechanism for said legs including a spring motor, a rotary shaft driven by the spring motor and terminating at each end in cranks, said cranks being oriented on said shaft in an out of phase relation with each other and each being connected to the driving portion of a respective one of said legs against lost motion relative to the legs;
- mounting means, means on said mounting means defining the other portion of said pin and slot connections, said other portions being in mating relation with a respective one of said first portions of said pin and slot connections on said legs whereby each leg will be positively driven by each crank and pivot about the pin and slot connection so that the first end of each leg will move in a walk simulating elongated eliptical path of travel.
