Abstract:
Example vehicle restraints with a barrier having rotational and translational motion are described. An example vehicle restraint includes a carriage frame movable vertically relative to the dock. A drive shaft is supported by the carriage frame. A drive unit is to rotate the drive shaft about a shaft axis and relative to the carriage frame. A hub is connected to rotate with the drive shaft about the shaft axis, the hub having an outer diameter surface that is radially off center relative to the shaft axis. A barrier defines a bore that encircles the outer diameter surface of the hub. The barrier is movable selectively to an extended position and a retracted position. The barrier being connected to move selectively to the extended position and the retracted position in response to relative rotation between the outer diameter surface of the hub and the bore of the barrier.

Claim (Index 23):
A vehicle restraint to selectively block and release a vehicle at a dock, the vehicle restraint comprising:\n a carriage frame movable vertically relative to the dock; a drive shaft supported by the carriage frame; a drive unit connected to rotate the drive shaft about a shaft axis and relative to the carriage frame; a hub connected to rotate with the drive shaft about the shaft axis, the hub having an outer diameter surface that is radially off center relative to the shaft axis; a barrier defining a bore that encircles the outer diameter surface of the hub, the barrier being movable selectively to an extended position and a retracted position relative to the drive shaft, the barrier being connected to move selectively to the extended position and the retracted position in response to relative rotation between the outer diameter surface of the hub and the bore of the barrier; a lifter borne by the hub; an abutment borne by the barrier, the lifter being in selective engagement and disengagement with the abutment, the lifter being positioned to move the barrier rotationally upward when the lifter is in engagement with the abutment, the barrier moveable relative to the carriage frame to a raised blocking position in response to rotation of the hub while the lifter is in engagement with the abutment, and to a stored release position in response to gravity urging the barrier down while the lifter is disengaged from the abutment; and a biasing element to couple the barrier and the carriage frame, the biasing element to urge the barrier toward the raised blocking position relative to the carriage frame, the bias element being insufficient to fully overcome gravity urging the barrier toward the stored release position.
