ABSTRACT:
This invention relates generally to devices which are designed to prevent loss of shopping carts from shopping center parking lots or other areas where use thereof is expected. More specifically, it relates to a particular wheel design which locks when removal is attempted and thereby provides a braking action under certain circumstances, namely when removal of the shopping cart from a given area is attempted. This locking of the wheel occurs when the longitudinal axis of the cart to which the wheel is attached, which is normally horizontal, is tilted away from the horizontal in order to negotiate curbs or when traversing a sloped surface such as a driveway and the like.
