Abstract: A device for locking a vehicle at a loading dock during loading and unloading. The device is provided with a carriage (11) adapted to be yieldably engaged by a depending safety bar (VB) of the vehicle. A hook-like member (26) is mounted on the carriage for movement between an operative mode wherein the vehicle safety bar is engaged and an inoperative safety bar-release mode. A power-actuated unit (35) is mounted on the carriage and effects movement thereof between the operative and inoperative modes. A linkage assembly includes a pair of pivotally connected links (40, 42). One of the links is pivotally connected to a movable portion (38) of the unit and when the latter is moving in one direction it causes the linkage assembly to move the hook-like member to the operative mode. When the unit portion is moved in a second direction, the linkage assembly moves the hook-like member to the inoperative mode. A control assembly (34) is adapted to actuate and deactuate the power-actuated unit.

Abstract: A wheel-activated vehicle restraint system including a support structure (30) disposed beside the path of the vehicle approaching the dock, and including a guide member (31) extending away from the dock face, and an elevated supporting member (32). A trigger assembly (50) is operatively connected to the guide member, and initially engages the wheel of the vehicle as it rolls toward the dock. A locking arm (70) operatively engages the supporting member to move from a stored position to a chocking position on the wheel as the wheel engages the trigger and moves it toward the dock. A trolley assembly (60) operatively connects the trigger assembly and the locking arm, the trolley assembly and the locking arm being connected at a connection point (71). The trigger assembly is selectively positionable relative to the connection point in response to the dimensions of the wheel, and the locking arm engages a bottom portion of the wheel, and moves along the peripheral surface of the wheel to a chocking position as the wheel continues to push the trigger assembly toward the dock.

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.

Abstract: The drive screw system comprises a drive screw (12) and a drive nut (26) adapted for driving a cooperating member such as a vehicle restraining device (50) between the proximal (12p) and distal (12d) ends of the drive screw (12). At least one bearing assembly (36, 38) is mounted to a track (32) for supporting the drive screw (12) and automatically moving between the proximal (12p) and distal (12d) ends of the drive screw (12) in response to the drive nut (26) to automatically maintain a predetermined maximum unsupported length of the drive screw (12). Each bearing assembly (36, 38) comprises two bearing supports (36d, 36p; 38d, 38p) connected at a fixed length and which are coaxially disposed relative to each other.

Abstract: A dock leveler assembly for a loading dock is provided having an adjustable ramp (11), a pivotally mounted lip (13) and a pivotally mounted barrier plate (16) both disposed at front edge portion of the ramp (11). The pivotal movement of the lip (13) and the barrier plate (16) are coordinated so that, when the lip (13) is in a depending stored position, the barrier plate (16) may be selectively adjusted to assume either an operative upwardly projecting vehicle barrier mode or an inoperative non-projecting mode allowing material handling equipment to load or unload the rear end of a vehicle parked adjacent the loading dock. When the lip (13) is in an operative cantilevered position bridging a gap formed between the ramp front edge portion and the bed of a parked vehicle the barrier plate assumes the inoperative mode allowing material handling equipment to pass over the ramp (11) and the lip (13) onto the bed of the parked vehicle.
