ABSTRACT:
A wheel chock, for use with tandem wheeled vehicles, having a pair of generally wedged shaped block members in spaced apart relation that are interconnected by a linkage assembly. The linkage assembly is operatively connected to a handle so as to horizontally displace the block members relative to each other. The first end of each block member has an angled contact panel configured for frictional engagement with the wheels so as to prevent movement of the vehicle. The handle is operatively connected to a link member configured for over-center displacement and the link member is pivotally connected to a drive member. In the preferred embodiment, the wheel chock comprises a locking member configured to maintain the linkage assembly in the engaged condition. The first ends of the block members has a vertical panel and is configured at an angle that will not become easily stuck under the wheels.
