ABSTRACT:
A suspension device for preventing swivel wheel wobbling over uneven terrain of a cart, such as a shopping cart, equipped with a pair of laterally opposite swivel wheels. The suspension device consists of a rigid elongated cross-member, fixedly mounted to the cart frame; an elongated arm, defining first and second opposite ends; a first mount, for mounting the arm to the cross-member for relative movement thereabout, whereby the arm first and second ends are movable relative to the ground in opposite directions. Stoppers restrain relative movement of the arm first and second ends within a prescribed play. A second mount rotatably mounts the two swivel wheels to corresponding opposite ends of the elongated arm, wherein the relative movement of the arm is responsive to ground terrain irregularities.
