ABSTRACT:
A brake mechanism is provided with brake pedals that are pivotably attached to opposite sides of a cart, or the like, by hinges and mounting brackets. Each brake pedal includes a downwardly extending leg having a friction foot at a distal end thereof. The brake pedals are pivotable to a braking position whereat the friction feet are frictionally engaged with the ground, thereby anchoring the cart, or the like, in place. One or more crossbars connect the brake pedals so that the pedals pivot in unison. A crossbar is provided which engages the underside of the cart to thereby limit the pivotal travel of the brake pedals. Adjustable length crossbars are preferred so that the dimensions of the brake mechanism can be adjusted for retrofit application with various sized dollies, or the like. A quick release locking device is provided to maintain the brake pedals in the braking position as well as in a freewheeling position. Alternatively, the friction feet can be provided on an angled crossbar which is operatively connected to the brake pedals. The friction feet are either spring biased or adjustable in length for optimum contact with the ground.
