ABSTRACT:
For a shopping cart wheel, for example, a toggle brake assembly which can be automatically actuated by an audio frequency signal when the cart is taken out of a designated area. When actuated, a battery-powered solenoid coil of the brake assembly is energized, drawing a coil spring catch away from a locking position on a toggle. The toggle then drops with a pivotal or axial movement to a braking position against the wheel, either against the outside or inside of the wheel depending on the brake embodiment used. As the wheel rotates in either direction, the toggle wedges or hooks to brake the wheel.
