Shopping cart tilt and tip prevention device
First Claim
1. An anti-tilt device for impeding tilting or tipping of a hand-driven cart or vehicle having a pair of front wheels and a pair of rear wheels, the device comprising:
- a rigid bracket for attachment to a selected wheel yoke or axle on an outer side of a wheel, the bracket having an upper portion and a lower portion;
a brake shoe of resilient material attached to the lower portion of the bracket and projecting downwardly from the bracket, the brake shoe having a lower surface for engaging the ground and providing a braking action if the cart is tilted or tipped, an inner surface and an outer surface; and
the brake shoe having a braking portion extending inwardly from the inner surface towards a wheel when the bracket is mounted on the wheel, whereby the braking portion will engage the wheel and resist rotation of the wheel when the cart is tilted or tipped such that the lower surface of the brake shoe engages the ground.

Abstract
An anti-tilt device for impeding tilting or tipping of a hand-driven, wheeled vehicle has a rigid bracket for attachment to a selected wheel yoke or axle on an outer side of the wheel and a resilient brake shoe attached to a lower portion of the bracket and projecting downwardly from the bracket. The brake shoe has a lower surface for engaging the ground and providing a braking action if the vehicle is tilted or tipped. The brake shoe has a braking portion extending inwardly from the inner surface towards a wheel when the bracket is mounted on the wheel. The braking portion will engage the wheel and resist rotation of the wheel when the cart is tilted or tipped.

10. A manually propelled wheeled vehicle, comprising:
-
a frame having a base; a pair of front wheels and a pair of rear wheels rotatably mounted on the base of the frame for engagement with a ground surface; at least one braking device mounted on the frame adjacent one of the wheels, the braking device comprising a rigid bracket attached to the frame, and a brake shoe of resilient material attached to the bracket and projecting downwardly from the bracket adjacent an outer side face of the wheel; and the brake shoe having a lower surface for engaging the ground and providing a braking action if the vehicle is tilted or tipped, and a braking portion extending towards the wheel for engaging the wheel and resisting rotation of the wheel when the vehicle is tipped to one side or tilted such that the lower surface engages the ground. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A combined vehicle caster and brake assembly, comprising:
-
a wheel supporting yoke, the yoke having an inner wall and an outer wall; a wheel axle secured between the inner and outer walls of the yoke; a wheel rotatably mounted on the axle between the inner and outer walls of the yoke; and a braking device mounted on the outer wall of the yoke; the braking device comprising a rigid bracket attached to the yoke, and a brake shoe of resilient material attached to the bracket and projecting downwardly from the bracket adjacent an outer side face of the wheel; and the brake shoe having a lower surface for engaging the ground and providing a braking action if a vehicle on which the caster is mounted is tilted or tipped, and a braking portion extending towards the wheel for engaging the wheel and resisting rotation of the wheel if the vehicle is tipped or tilted. - View Dependent Claims (18, 19)
