ABSTRACT:
A bumper assembly for a shopping cart having a wire basket with horizontal wires bent so as to define a front corner of the basket. The assembly comprises a resilient, extruded, polymeric bumper having front, back, and side apertures extending longitudinally through the bumper, which is slotted so as to accommodate such wires at the front corner. The assembly comprises a pin extending through the back aperture with an interference fit so as to confine such wires between the pin and a front wall of the bumper. The front wall, which partly bounds the front aperture, is spaced from such wires when the front wall is unstressed. The front and side apertures lend enhanced cushioning ability to the bumper, which can yield in flexure, as well as in compression.
