ABSTRACT:
A motor-driven, rope-jumping doll. The doll features a conventional toy that closely imitates rope-jumping by a human. A battery powered motor is activated and deactivated by lightly pressing on top of the doll's head. Once in motion, the doll appears to swirl the rope overhead and underfoot while effecting a jump each time the rope passes its zenith and nadir. The "timing" jump and the rope-skipping jump, combined with a true swirling motion applied to the rope by principally the "elbows" and "wrists" of the toy sincerely emulate one rope-jumping technique used by human beings. An eccentric, asymmetrically spiraled cam and a biasing spring are used to effect the two-jump characteristic by shuttling a discrete internal mass between a first and a second position, twice for each rotation of the cam.
