ABSTRACT:
A wheel-actuated vehicle restraint device is provided for restraining at least one wheel of a vehicle during loading and unloading thereof. The vehicle restraint comprises a lock assembly comprising an actuation assembly for initially engaging the wheel of the incoming vehicle and a lock assembly for chocking the wheel in response to engagement between the wheel and the actuation assembly. The lock assembly is operatively connected to the actuation assembly at a connection point such that the connection point is selectively positionable in response to the dimensions and location of the wheel for insuring that the lock assembly engages a bottom portion of the wheel and moves along the peripheral surface of the wheel to a chock position. In one embodiment, the actuation assembly comprises a trigger assembly disposed to engage the wheel and a trolley assembly operatively connecting the lock assembly and trigger assembly. The trolley assembly comprises a variable length biasing link such that the length of the link varies in response to the wheel dimensions and location, thereby positioning the lock assembly to engage the bottom portion of the wheel before moving to the chock position.
