Abstract
A braking system designed to be an integral part of a shopping cart. The braking system consists of a hand-operated brake that is normally engaged. The user disengages the braking system to move the shopping cart. The braking system is also disengaged when the shopping cart is nested with other shopping carts to allow multiple carts to be moved without the brakes being engaged. The mechanical link from the handle to the brake is enclosed within the frame to reduce potential damage to the mechanism. The mechanical link consists of a hand-activated handle that is pushed down to disengage the brake, and when the handle is not depressed, the handle raises by gravity and applies the brake.

A shopping cart with a hand activated wheel braking mechanism comprising:
- a structural frame connecting an open basket section consisting of a bottom and at least one side wall, and
- a handle located at one side of the basket, and
- at least three wheels rotationally connected to the structural frame located below the corners of the basket, and
