Abstract: This invention is a variable automatic forward/reverse control device for an unattended baby cart which is particularly designed for the housewife who is too busy at home to take care of her baby in the cart. Placing the baby in this cart equipped with this control device and taking advantage of the device may make this cart automatically advance a preset distance and then automatically back a preset distance, without worrying about this cart ramming against a room wall or some stationary objects indoors. Thus, the baby will feel quite safe and not cry. In addition, this cart may be provided with music to let the housewife use her spare time to do some handicraft or other chores. Furthermore, the timing equipment or rang-finding computer in the control device may be adjusted to close to zero time so that this cart can slightly vibrate to-and-from in situ so that in such circumstances, the baby will not cry.
Abstract: A running toy has a detachable non-circular wheel attached to an axle driven by a known prime mover, such as spring-powered prime mover and the like. The wheel is molded from an elastic material, such as rubber, soft plastic and the like, and has large projections and recesses formed on the peripheral surface thereof to make the running toy perform various interesting motions which are not conventionally obtained as well as to offer favorable effects.
Abstract: This disclosure pertains to a rigid board-like surface having three casters affixed to the undermost surface thereof. Two of the casters are disposed in spaced apart relationship and co-axially aligned at one end of the board. The remaining caster is located at the other end of the board. Each caster utilizes an eccentric wheel, causing the board to undulate when rolling down an inclined surface. An inverted U-shaped rail is affixed to the uppermost surface of the board to which is attached a rope-like cord utilized to provide a grasp for the user of the apparatus.
