Abstract:
1. An articulated walking toy device configured for movement across a surface, the toy device comprising: a frame; a plurality of leg assemblies movably coupled with the frame, each leg assembly including a leg member configured to rotate with respect to the frame about separate first and second axes, the first and second axes being at least generally transverse to one another; and a drive mechanism operatively engaged with the plurality of leg assemblies so as to actuate each of the leg members of the plurality to rotate about the first and second axes in a like, predetermined, repeatable cycle of movement, with at least some of the leg members of the plurality being out of phase with other leg members of the plurality to produce an anatomic-like gait of the toy device on the surface upon actuation of the drive mechanism; wherein each leg assembly further comprises: a base member movably disposed on the frame, the base member having a channel therein with first and second follower surfaces, the leg member being engaged with the base member so as to pivot with respect to the base member about the second axis; and first and second cams rotatably coupled with the drive mechanism and positioned in the channel of the base member in contact with the first and second follower surfaces, respectively, to cyclically rotate the base member and the leg member with respect to the first axis.
