An automatic braking apparatus for inclusion with a user-propelled grocery cart, luggage cart or the like is provided which automatically brakes at least one of the cart wheels when not in use and which allows easy, convenient, and automatic release of the braking mechanism by the user during operation. The preferred apparatus includes a braking mechanism shiftable between a braked position for braking at least one cart wheel and a released position for releasing the wheel and including a spring for biasing the mechanism toward the braked position, an intermediate structure pivotally coupled adjacent the cart handle and interconnected with the brake mechanism; and an operating member pivotally coupled with the handle and intercoupled with the intermediate structure including a handle portion for grasping by the cart user. In operation, the user grasps the handle portion and pushes generally forwardly which rotates the operative member, the intermediate structure, and the braking mechanism to the released position; the spring automatically shifts the apparatus components to the braked position when the handle portion is released.

An automatic braking apparatus in combination with a user-propelled grocery cart, luggage cart or the like having support wheels and a transverse handle rearwardly spaced from the body of the cart, said braking apparatus comprising: a braking mechanism for shiftably coupling with the cart and for shifting between braked and released positions, said mechanism including braking means for braking at least one support wheel when in said braked position and for releasing said wheel for unbraked rotation thereof when in said released position; pivot structure for pivotally coupled with the cart about a fixed pivot point adjacent one end of the cart handle for pivotal shifting between braked and released positions, said pivot structure presenting first and second, opposed, connection portions; connecting means connecting said first connection portion with said braking means for mutual, corresponding, shifting of said pivot structure and braking means between said braked and released positions; and handle means for pivotally coupling with the cart handle for pivotal shifting between braked and released positions and including means for coupling with said second connection portion for mutual, corresponding, shifting of said handle means and pivot structure, and thereby said braking means, between said braked and released positions, said handle means and pivot structure being shiftable in opposed rotational directions during mutual corresponding shifting between said braked and released positions.
