Abstract
Abstract A powered display (10) for visual matter (40) is mounted on a shopping cart (12) and powered by movement of the shopping cart. In one preferred embodiment of the present invention, the display is rotary and powered by a transmission system having a follower gear (62) operably interconnected with the display and meshed with a drive gear (60) that is attached to one end (54) of a bowden cable (16). The opposite end of the bowden cable is drivingly linked to a wheel (22) of the shopping cart by a follower gear (64) that meshes with a drive gear (66) mounted on the wheel. Rotation of the shopping cart wheel is transmitted via the bowden cable to the display (10) to cause rotational display of the visual matter contained thereon.
