Latching mechanisms for removable chocks

摘要

Example wheel restraint systems (10) include example wheel chocks (20a) for blocking a wheel (12) of a vehicle at a loading dock. In some examples, the wheel chock (20a) is movable between a stored position and a wheel -blocking position. In the wheel -blocking position, the chock latches onto a track (22) that is mounted to a driveway of the loading dock. In the stored position, the chock (20a) is spaced apart from the track (22). In some examples, a lifting mechanism (30), such as a hoist (30a) or a spring - loaded articulated arm (30b) helps carry at least some of the chock's (20a) weight as the chock (20a) is manually moved between its stored and wheel -blocking positions. In some examples, the chock (20a) includes a rotatable lever (44) for selectively latching and unlatching the chock (20a) to the track (22).
