  • Patent number: 5236066
    Abstract: A wheel brake for shopping carts and other wheeled equipment is disclosed. Typically, shopping carts and other wheeled equipment have a yoke depending from a lower end of a leg support, the yoke including a pair of generally parallel downwardly extending arms. A wheel is rotatably mounted on an axle extending between these downwardly extending arms. In order to provide selective braking engagement of the wheel to immobilize the shopping cart or other wheeled equipment, a brake tongue is pivotally mounted at one end to the yoke above the wheel and extends across at least a part of the wheel. A foot pedal is pivotally mounted to the yoke in spaced relationship to the brake tongue for movement between engaged and released positions relative to the wheel. The foot pedal includes a depending brake element for engaging and depressing the brake tongue into selective braking engagement with the wheel when the foot pedal is moved into engaged position by a user.
