20090117820ARTICULATED WALKING TOY - An articulated walking device, configured for movement across a surface, includes a frame and a plurality of leg assemblies movably coupled with the frame so as to at least partially support the frame for movement across the surface. Each leg assembly includes a leg member configured to rotate with respect to the frame about a joint. The joint is formed by a pin passed through an at least generally hour glass shaped aperture to provide rotational movement of the leg member with respect to the frame about at least first and second axes of rotation intersecting in the joint. A drive mechanism is operatively engaged with the plurality of leg assemblies so as to actuate each of the leg members to rotate about the first and second axes in a like, predetermined, repeatable cycle of movement. At least some of the leg members are out of phase with other leg members to produce an anatomic-like gait of the toy device upon actuation of the drive mechanism.05-07-2009
