Abstract
A wheel chock assembly for preventing movement of a wheel relative to the surface on which it is resting includes a pair of wedge members positionable in spaced apart relation one to another and interconnected by a bar. At one end, the bar is slidingly received by aperture means provided in a first wedge member, and at its other end it is fixedly attached to the second wedge member. A tab having an aperture is slidingly received by the bar and is disposed adjacent the first wedge member. Abutment of a portion of the tab against the first wedge member causes pivoting movement of the tab and locking engagement between an edge of the tab aperture and the bar, thereby preventing relative outward movement of the two wedge members.
