ABSTRACT:
A spacer device for shopping carts mounts on the wheeled frame of a cart in order to prevent lateral binding of the frames of a pair consecutively nested shopping carts. The spacer has a central body portion that is secured alongside a frame portion of a first one of the pair of shopping carts by a mounting structure so that when the carts are nested, the central body is interposed between the frame portions of the two carts thereby preventing direct contact and, thus, binding. The central body has an exposed glide surface formed of a low friction material so that the frame portion of the second cart slideably contacts the glide surface for lateral sliding movement. The mounting structure may be C-shaped resilient clips that snap fir onto circular frame portions.
