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 12):
A vehicle restraint to selectively block and release a vehicle at a dock, the vehicle restraint comprising:\n a drive shaft supported by a carriage frame; a drive unit 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 movable in engagement with and disengagement from the abutment, the lifter to move the barrier rotationally upward when the lifter is in engagement with the abutment; a stop borne by the barrier; and a rocker coupled to the carriage frame, the rocker including an upper facing surface and a lower facing surface, the rocker being connected to move selectively to a forward position and a rearward position relative to the carriage frame, the rocker being configured to move between the forward position and the rearward position in response to the upward movement of the barrier causing engagement between the stop and the lower facing surface of the rocker, the rocker being further configured to inhibit downward movement of the barrier when the stop is in engagement with the upper facing surface of the rocker.
