| 141 | Vehicle restraint | US863054 | 1986-05-14 | US4695216A | 1987-09-22 | Kjell I. Erlandsson |
| A vehicle restraint for preventing a vehicle such as a truck from accidentally pulling away from a loading dock during a loading operation. The vehicle restraint comprises a mounting plate mounted on the front vertical face of the loading dock and a slide is mounted for movement on the mounting plate and is biased to an upper position. The slide is provided with an angular front surface that is inclined downwardly and outwardly. When a truck backs toward the loading dock, an abutment, such as an ICC bar at the rear end of the truck, will engage the inclined surface, wedging the slide downwardly against the force of the biasing means and the ICC bar will then be received within a recess or notch located in the upper edge of the slide. To release engagement of the ICC bar from the notch, a release bar is moved upwardly into engagement with the ICC bar, thereby driving the slide downwardly against the force of the biasing means to release the ICC bar from the notch and enabling the truck to pull away from the dock. | ||||||

| 146 | Truck locking device | US367296 | 1982-04-12 | US4488325A | 1984-12-18 | David E. Bennett; Joseph R. Driear |
| A device for locking a vehicle to a loading dock during a loading operation. The device includes a frame mounted on the front surface of the dock beneath a pit which houses an adjustable dockboard. A slide assembly is mounted for vertical movement on the frame, and the slide assembly includes a locking member adapted to engage an abutment on the vehicle, as the slide assembly is elevated. To raise and lower the slide assembly, a motor is mounted on the slide assembly and drives a gear that engages a rack carried by the frame. The rack is spring biased to an upper position, and on operation of the motor in one direction, the slide assembly is raised to bring the locking member into engagement with the abutment on the vehicle. Continued operation of the motor will then move the rack downwardly relative to the gear and slide assembly, and downward movement of the rack will activate a switch to cut off power to the motor. After the loading operation is completed the motor is driven in the opposite direction to lower the locking member to its storage position. The movement of the slide assembly and locking member can be tied into the operation of the lip of the dockboard in which the motor will automatically be operated to move the locking member upwardly toward the locking position when the lip is raised from its pendant position, and the motor will be operated in the reverse direction when the loading operation is completed and the lip is returned to its pendant position. | ||||||

| A releasable locking device is provided which is particularly suitable for retaining a parked vehicle against a loading dock or the like during loading or unloading thereof. The device includes a pivotally mounted hook-like member movable between operative and inoperative modes. The member is secured to the front side of the loading dock by a carriage having a first section on which the hook-like member is mounted, and a second section affixed to the dock front side. The first section is adjustable relative to the second section in a substantially vertical plane. The first section is biased to normally assume a predetermined rest position which is at a maximum elevation with respect to the roadway supporting the vehicle. A reversible electric motor is mounted on the carriage first section and actuates the hook-like member between the operative and inoperative modes. When in an operative mode, the hook-like member interlockingly engages the parked vehicle. When in an inoperative mode, the hook-like member assumes a vehicle-release position. Manual controls are provided for regulating the operation of the motor. The carriage first section includes an outwardly projecting cam segment which is engaged by the vehicle when being maneuvered into a parked position and will cause the first section to move vertically downwardly thereby enabling the member to interlockingly engage the vehicle in response to the manual controls. | ||||||

| 160 | Vehicle restraints with anti-rotation features | US13599770 | 2012-08-30 | US09227799B2 | 2016-01-05 | Andrew Brooks |
| Example vehicle restraints having example anti-rotation features are disclosed herein. In some examples, an actuator in the form of a hydraulic cylinder moves both a vehicle barrier and its brace between stored and activated positions. If the vehicle pushes the barrier from an upper blocking position to an intermediate blocking position, the brace helps support the barrier at the intermediate blocking position to prevent the vehicle from further pushing the barrier to its stored position. To avoid damaging a cover plate or other relatively weak areas of a vehicle's RIG (rear impact guard), some example barriers disclosed herein exert a holding force that is less at the upper blocking position than at the intermediate blocking position. | ||||||
