Abstract: A sound emitting advertising and information display device which has a roller housing which has an internal chamber. A sheet member is wound on a roller and is contained within the internal chamber. The sheet member is to be manually extendable from the housing with advertising indicia that is located on the sheet member to then be capable of being read by a human. During the time of extending of the sheet member, a sound is emitted that is to correspond with the advertising indicia. The advertising display device is to be attached to the front end of a product supporting shelf in a store.

Abstract: A doll includes a torso slidingly supported upon the waist of the doll and configured for vertical movement between a raised and lowered position. A pair of springs bias the doll torso toward the raised position. The doll supports a pair of arms and a cam in a rotational attachment to the torso. A pedestal supported upon the doll lower body extends through a guiding bore formed in the doll torso and supports an upwardly extending pin which operates the cam causing pivotal movement of the dolls arms between an arms-lowered and arms-raised position. A flexible jumprope is secured to the dolls hands and the upward and downward pivotal movement of the dolls arms caused by movement of the torso provides a simulation of jumprope activity.

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.
