The apparatus includes a generator provided on the vehicle and a linear motion to rotary motion converter that is connected between a wheel of the vehicle and an armature of the generator. Reciprocating movements of the wheel relative to the vehicle body are converted by the motion converter to rotations of the armature in the generator which produces electricity for recharging the battery of the vehicle.

Abstract: A rocking device is described for receiving a lower part of a carriage, perambulator, cot or the like in particular to rock an infant therein, with oscillation means to impart an oscillating motion thereto comprising an elongate roller (2) mounted about a generally longitudinal axis, and drive means (9) associated therewith to cause the roller to rotate, the transverse shape of the roller and the position of the axis together being such that the roller imparts an oscillating motion to the carriage in mechanical engagement therewith in use. A method of rocking a carriage, perambulator, cot or the like is also described.

Abstract: A device for automatically rocking a stroller. Winding structure includes a connecting rod, whose first end is eccentrically mounted to the spring structure and whose second end is equally eccentrically mounted to the wheel axle extension so that the forward movement of the stroller winds the spring structure. The rocking structure includes a rod whose far end is mounted eccentrically to the wheel axle extension and whose forward end is less eccentrically mounted to the spring structure to ensure that the rod assumes a reciprocating motion during the unwinding of the spring structure. The user switches from winding mode to rocking mode. In an alternative embodiment a first rod attached to the shaft includes a lever that assumes different positions, the different lever positions changing the degree to which a second rod is eccentrically mounted to the spring structure and determining whether the device is in winding or rocking mode.

Abstract: A motorized stroller includes a first frame member adapted to support a seat for placement of an infant and a pair of wheels for movement of the first frame member along the ground. The motorized stroller also includes a motorized wheel assembly having a motorized wheel frame adapted for attachment to the first frame member, a pair of wheels coupled thereto, a motor for driving at least one of the wheels attached to the motorized wheel frame, and a gear reduction unit operatively coupling the motor to at least one of the wheels of the motorized wheel frame. When the motor operates, power is provided from the motor by the gear reduction unit to at least one of the wheels of the motorized wheel frame which enables the stroller to move in one of a forward and reverse direction without power for movement being provided by a user. The motorized wheel assembly is capable of being disengaged such that the motorized stroller can be manually pushed by a user and therefore used in a conventional fashion.

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.
