ABSTRACT:
A rotary display (10) for printed advertisements (40) is mounted on a shopping cart (12) and advanced by movement of the shopping cart. The rotary display includes an elongated rotary display drum (14) on which the advertisements are disposed. The display drum is drivingly linked by the meshing of a follower gear (62) 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 drum to cause rotational display of the advertisements contained thereon.
