Abstract: A shopping cart brake adapted for use on commercially available carts designed to provide an automatic brake which remains engaged to hold the cart in a stationary position, unless the user manually disengages the brake of the cart for moving the cart. Upon parking the shopping cart, the interaction of the forward basket portion of the last cart in the stack contacting the back panel of the preceding cart automatically disengages the brakes of the preceding cart so that the brakes of the last cart in the stack of carts will be automatically engaged upon parking the cart and a user must manually disengage the brake of the last cart in order to move the stack of carts.

Abstract: A brake for restraining movement of rolling carts. Attachable to heavy tool carts as used in machine and auto shops, a mechanical brake of heavy-duty construction uses a spring-biased bolt to hold a brake pad. The brake pad is of sturdy but resiliently flexible material to engage the floor. To engage the brake, a brake set lever is depressed as by stepping on the lever. The brake set lever is pivotably attached to the brake chassis and has mechanical advantage over the spring-biased bolt. The other end of the brake set lever prevents the longer end from flying up when the brake is released. When the brake is engaged, it is held frictionally in place by the spring-biased brake release lever. The bolt shank passes through the brake release lever. The spring-biasing of the bolt causes the brake release lever to more tightly engage the bolt shank to hold the bolt in place. To release the brake, the spring-biasing of the brake release lever is overcome as by stepping on the lever.
