<p>A walking mechanism, particularly intended for the locomotion of toys, but capable of being adapted to other uses, is disclosed. The mechanism includes four legs, one at each corner of a platform. Lever arms integral with the legs extend to central areas on either side of the platform, alongside substantially vertical side panels. A drive rod is pivotally connected to a fulcrum support positioned between the side panels. The drive rod extends through slots in the side panels and engages slots in the lever arms. A motor causes reciprocating movement of the drive rod, which pivots about the fulcrum support. Motion of the drive rod produces motion of the leg. Cam and cable means are provided for lifting and planting the legs at appropriate times to simulate a quadruped walking motion. Means are provided for varying the location of the fulcrum support in order to produce a greater step length on one side of the platform than on the other, thereby causing the platform to turn. Both forward and backward movement are possible.</p> |
