Abstract
An improved shopping cart brake for attachment to the rear leg of a shopping cart is disclosed, the brake for preventing the rotation of a non-inflatable tire on the rear leg of the shopping cart. The shopping cart brake includes a connecting arm, which is removably and adjustably attached to the rear leg of the shopping cart. The brake also includes a split yoke, which is pivotally connected to the connecting arm. The split yoke has two braking flanges which engage and apply frictional force to the sides of the non-inflatable tire to prevent the tire from rotating. An actuator is also included, the actuator being integral with the split yoke and for applying force to the split yoke to engage the braking flanges with the sides of the non-inflatable tire. The shopping cart brake also includes an adjustable tension bar between the braking flanges which may be used to increase or decrease the frictional force the braking flanges apply to the non-inflatable tire. When the tension bar is adjusted properly, the braking flanges may be disengaged from the sides of the non-inflatable tire by merely moving the cart to the rear. A pop-up spring is also included. The pop-up spring is located between the connecting arm and the split yoke and biases the split yoke to a normal position where the braking flanges do not contact the sides of the non-inflatable tire when the brake is disengaged.
