ABSTRACT:
A shopping cart anti-theft apparatus is described. The apparatus is designed to be mounted on the swivel caster of a wheel of a shopping or other cart, and comprises a locking assembly and an actuating assembly for operating the locking assembly. The actuating assembly includes a magnet responsive to the cart passing over a magnetic barrier to actuate the locking assembly. Thus, if a user attempts to remove a cart from a store parking lot by pushing it over a magnetic barrier arranged around the periphery of the parking lot, the swivel caster will be maintained in an off-center, turn-inducing position such that the cart can only travel in a circle if pushed.
