| 121 | Vehicle restraint with powered latching member | US386807 | 1999-08-31 | US06162005A | 2000-12-19 | Ben Fritz |
| A loading dock and vehicle restraint assembly for securing a vehicle during loading operations. The vehicle restraint comprises a latching member (e.g., a hook) movable between an engaged position and a disengaged position, and an electromechanical brake coupled to the latching member and movable between a restraining position, where the latching member is restrained from movement, and an unrestraining position, where the latching member can be moved. Preferably, the brake is mechanically biased toward the restraining position (e.g., by a spring), and is moved to the unrestrained position by an electromagnet. The assembly can be used to perform a method of restraining a vehicle at a desired location using a vehicle restraint having a latching member and a brake coupled to the latching member. The method includes the steps of parking the vehicle at a desired location, positioning the brake in an unrestraining position to allow movement of the latching member; moving the latching member from a disengaged position to an engaged position, and positioning the brake in a restraining position to restrain movement of the latching member. The new design is also adapted to be easily installed onto existing vehicle restraints. | ||||||

| A vehicle restraint for a truck loading dock includes an actuator that rides up with a carriage to sense that a truck's ICC bar is within a predetermined region before fully extending a restraining member to engage the bar. The carriage and restraining member are raised and lowered by a drive unit, such as a cable extending from a winch. The winch may be attached directly to the carriage, or optionally remotely mounted to the dock. One end of the cable connects to a spring that compensates for incidental vertical movement of the ICC bar caused by the truck being loaded or unloaded. Large downward movement of the ICC bar is accommodated by a clutch associated with the winch. For large upward movement, the winch automatically restarts to pull the carriage up to meet the new height of the bar. An optional ICC bar deflector mounted at the base of the dock, along side the carriage, wedges underneath an exceptionally low ICC bar as the truck backs into the dock. The deflector guides and lifts the low bar above the actuator to prevent premature and uncontrolled extension of the restraining member. | ||||||

| 127 | Vehicle restraint | US245541 | 1994-05-18 | US5454682A | 1995-10-03 | James C. Alexander |
| A vehicle restraint employs a 4 bar linkage to lift a restraining member to a position that engages a vehicle thus restraining it at a loading dock. The linkage is upwardly based to hold the unit in an engaging position and may be retracted by using any of a number of mechanical techniques such as hydraulic electric or pneumatic power. The 4 bar linkage transfers all loading on the unit from the ICC to the frame thus isolating any driven members from overloads. A secondary hook mounted to the 4 bar linkage is pivotally spring loaded to limit vehicle travel away from the dock and to extend the capture range of the device in the case of ICC's bars that are damaged or mounted at non-standard positions at the rear of the vehicle. | ||||||

| 134 | Vehicle restraint | US550928 | 1990-07-11 | US5071306A | 1991-12-10 | James C. Alexander |
| A vehicle restraint mountable against a dock face uses a linearly extensible actuator member to move a flat plate restraining device into a vehicle release or restraint position. The plate carries a bracket having a cam profile which via a connection or latch arm converts the linear movement of the drive member into rotational movement of the restraining plate. In the vehicle restraining position all loading on the restraining device is transmitted to the frame without any force component on the actuator. | ||||||
| 135 | Truck actuated vehicle restraint having a pivotable inclined surface | US410736 | 1989-09-21 | US4973213A | 1990-11-27 | 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 frame mounted on the front vertical surface of the loading dock and a slide is mounted for movement on the mounting plate and is biased to an upper position. An inclined cam member is pivoted to the upper portion of the outer end of the slide and extends downwardly and outwardly from the slide and the lower end of the cam member is pivotally connected to the mounting frame via a link of fixed length. 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 cam member, wedging the slide downwardly against the force of the biasing member, and the ICC bar will engage a notch located in the upper edge of the slide to block outward movement of the truck from the loading dock. 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 member to release the ICC bar and enable the truck to pull away from the dock. | ||||||

| 137 | Vehicle restraint having a snubbing restraining member | US87830 | 1987-08-21 | US4815918A | 1989-03-28 | Mark A. Bennett; Douglas H. Massey |
| A vehicle restraint to be mounted on a loading dock for preventing accidental movement of a vehicle, such as a truck, from the dock during a loading operation. A hydraulic cylinder unit is connected through a flexible member, such as a chain, to a hook-like restraining member. By extending and retracting the hydraulic cylinder unit, the restraining member can be moved between the lower storage position and an upper operative position where it engages the ICC bar of the truck. In addition, a resilient member, such as a gas spring, is operably connected to the chain at a location between the attachment of the hydraulic cylinder to the chain and the attachment of the chain to the restraining member. The resilient nature of the gas spring will permit limited movement of the chain to accommodate vertical float of the ICC bar and truck bed during a loading operation. The restraining member includes an outer section or tip that can be moved inwardly toward the dock by a separate fluid cylinder to snub the tip against the ICC bar to prevent fore and aft rocking of the truck during the loading operation. | ||||||
| 138 | Vehicle restraint having an upwardly biased restraining member | US854386 | 1986-04-21 | US4767254A | 1988-08-30 | Jonathan W. Kovach; Martin P. Hageman |
| A vehicle restraint for preventing accidental movement of a vehicle away from a loading dock. The vehicle restraint comprises a frame mounted on the front face of the dock and a restraining member having a hook-like configuration is mounted for movement on the frame between the lower storage position and an upper operative position where the restraining member is engaged with an abutment, such as an ICC bar, on the vehicle. The restraining member is biased upwardly to the operative position and a power operated unit is arranged to move the restraining member downwardly from the operative position to the storage position where it is locked in the storage position by a releasable latch. On release of the latch, the biasing mechanism will move the restraining member upwardly into engagement with the ICC bar, and the biasing mechanism enables the engaged restraining member to follow both upward and downward movement of the ICC bar during a loading operation. | ||||||
