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.
Claims11
In a motor-driven, rope-jumping toy that features a bi-pedal supported torso with a head and moveable arm pair, and includes a jump rope, an improvement thereto comprising the combination of:
- motor activation-deactivation means disposed beneath said head and responsive to tactile force applied to said head;
- swirl-emulation means for continuously effecting a forearm 360.degree. swirling motion and a concomitant upper arm pendulous motion that are imitative of human arm motions during rope jumping activity;
- and
- motivation means for causing staccato upward jumps of said torso in a ratio of two discrete jumps for every said 360.degree. swirling motion.
A motor-driven, rope-jumping device of a conventional rope swirling doll configuration comprising:
- a torso having thereon a head and supported by a fixed leg pair, said torso containing therein a motor, a gear train that transfers power from said motor via a common shaft to a spiral cam means and to a transversely mounted rotating crank that terminates in a rope-holding hand at each end, a fixed anvil means and a moveable hammer means, said hammer means responsive to both camming motion of said cam means and a biasing spring to alternately shuttle between a first position and second position relative to said torso section;
- and,
- motor on/off switching means for applying/removing power continuity between said motor and a power source, said switching means responsive to tactile force applied to said head.
An improvement in a rigidly upright standing doll, having a torso, a moveable head and which is motivated to emulate rope jumping by continuously swirling a rope, each end thereof captured in a hand, overhead and underfoot while jumping upward to allow passage of said rope underfoot, said improvement comprising in combination:
- a drive mechanism for effecting a 360.degree. swirling motion of the rope ends while concurrent therewith causing said doll to effect two discrete upward jumps in response to reciprocations of an internal weight-mass;
- and
- on/off switching means located proximate to said head and responsive to tactile force thereon for activating/deactivating said drive mechanism.
