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 1):
A vehicle restraint to selectively block and release a vehicle at a dock, the vehicle restraint comprising:\n a carriage frame movable relative to the dock; a drive shaft supported by the 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 surface having an axis of rotation that is radially off center relative to the shaft axis; a barrier defining a bore to receive the outer surface of the hub, the barrier being movable between an extended position and a retracted position in response to the outer surface of the hub rotating relative to the barrier; a first bearing interposed between the hub and the barrier to enable rotation of the hub relative to the barrier; a lifter borne by the hub; an abutment borne by the barrier and movable between an engaged position and a disengaged position relative to, the abutment, the lifter to move the barrier rotationally upward when the lifter is in engagement with the abutment; a stop borne by the carriage frame; a catch borne by the barrier; a rocker coupled to the barrier and connected to rotate about a rocker axis relative to the barrier, the rocker to rotate selectively to a forward tilted position and a rearward tilted position relative to the barrier, the rocker being in a first engaged relationship with the catch when the rocker is in the forward tilted position, the rocker being in a second engaged relationship with the catch when the rocker is in the rearward tilted position, the rocker configured to engage and disengage the stop, the barrier having a longitudinal axis intersecting and lying perpendicular to the shaft axis and the rocker axis, the barrier being movable relative to the carriage to position the longitudinal axis at an angular position lying rotationally between a horizontal plane and a vertical plane, the rocker configured to have a center of gravity situated such that when the rocker is in the rearward tilted position the center of gravity urges the rocker toward the forward tilted position when the longitudinal axis is at an angle greater than 35 degrees from horizontal; and a second bearing coupled to the rocker to enable rotation of the rocker relative to the barrier.
