  • Automatic shopping cart brake engaged by nesting of carts
    Patent number: 5325938
    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.
