Abstract
The wheel chock includes a locking mechanism that can be held in a locked state when properly positioned on a base plate. The locking mechanism includes a positioning unit having at least one tooth provided to engage a side of a corresponding one of the blocking elements in a latched engagement when the positioning unit is in the fully locked position. The locking mechanism also includes first means for moving the positioning unit from the unlocked position towards the fully locked position, and second means for selectively holding the positioning unit in the fully locked position.
