A braking mechanism (20) for a grocery cart or the like is disclosed as including a braking assembly (50) that is selectively shiftable between braking and non-braking positions and a handle assembly (52) interconnected to the braking assembly (50) for effecting the selective brake assembly shifting. The braking assembly (50) includes a chock element (60) shiftably mounted adjacent at least one of the cart wheels (26) and configured for wedging engagement between the periphery (65) of the wheel (26) and the support surface (66) to impede forward movement of the cart (22). The handle assembly (52) includes a tubular body (112) for fitting over the existing cart handle (28) and a pair of rotor cup assemblies (118, 120) supporting the tubular body (112) on the cart body (24, for selective pivotal movement substantially about the longitudinal axis of the cart handle (28). In operation, the user grasps and pivots the tubular body (112) for corresponding shifting of the braking assembly (50) from the braking position to the non-braking position thereof. Once the tubular body (112) is released by the user, coil spring (192) disposed within at least one of the rotor cups (118, 120) biases the braking assembly (50) toward the braking position thereof.

[ We claim:] [1.] A cart comprising:a cart body;a plurality of rotatable support wheels operatively coupled to said cart body for moveably supporting the cart body on a support surface, with each of the wheels presenting a periphery; anda braking mechanism being operatively connected to said cart and including a braking assembly that is selectively shiftable into and out of a braking position in which forward movement of the cart body is impeded,said braking assembly including a shiftable chock element having at least a portion thereof that is located generally forward of one of the wheels and is configured for selective wedging engagement between the periphery of the one wheel and the support surface when the braking assembly is in the braking position,said cart body having a rearwardly disposed nesting panel pivotal between an open position and a closed position for allowing nesting of a plurality of carts when said panel is pivoted to said open position, said cart further including means interconnecting said nesting panel with said braking mechanism for shifting said braking assembly out of the braking position when the panel pivots to said open position.
