摘要： A vehicle-activated support assembly control system is provided which comprises a sensor assembly which senses the position of the vehicle relative to the dock leveler and an actuation assembly which is operatively connected to the support assembly so as to actuate or maintain the support assembly in a retracted position in response to the position of the vehicle. The actuation assembly is adapted to automatically position the support assembly between (1) a retracted or non-supporting position when the vehicle is in close proximity to the loading dock and (2) an active supporting position when the vehicle is greater than a predetermined distance from the loading dock. The control assembly is adapted to activate the support assembly and move the support assembly to the active supporting position as the vehicle pulls away from the dock leveler but before the lip loses contact with the vehicle. The control system deactivates the support assembly when the lip is safely supported on the vehicle bed or is within a predetermined distance in which the lip is capable of engaging the vehicle bed. The control system permits the support assembly to be in the active supporting position when the lip is extended but not safely supported by the vehicle bed.

摘要： A mechanical restraint is provided for use in securing a parked vehicle to a stationary structure, such as a loading dock, while the vehicle is being loaded or unloaded. The restraint includes a first member fixedly mounted on the front wall of the loading dock, and a second member mounted on the first member for movement in a vertical plane and for hinged movement about a vertical axis between operative and inoperative modes. The second member is provided with an elongated first section which is in sliding engagement with the first member. The second member, when in a raised position is adapted to turn about the longitudinal axis of the first section which is coaxial with the hinge axis of the second member. The second member is provided with an elongated second section which projects angularly from the upper end portion of the first section. The second section includes a distal end portion provided with a depending projection. When the second member is in the operative mode, the distal end portion is adapted to overlie and interlock with a transverse bar, such as an ICC bar, which depends from the rear portion of the parked vehicle. The second section of the second member includes a safety element which effects separation of the first and second members only when an external pulling force above a predetermined amount is exerted on the distal end portion of the second section.

摘要： An assembly is provided for weather-sealing an elongated joint formed between a first member and a second member when said members are disposed at a predetermined relative position. The assembly includes an elongated piece having elongated interconnected first and second sections extending angularly relative to one another. The piece is removably carried by an elongated bracket fixedly secured to a side of one of the members defining the joint. The bracket is provided with an inner wall section, an outer wall section in spaced substantially face-to-face relation with the inner wall section, and a bridge section interconnecting a pair of corresponding elongated edges of the wall sections. The wall and bridge sections coact to form an elongated pocket having a first opening at one end. Corresponding second elongated edge portions of the inner and outer wall sections are disposed in spaced relation and define an elongated second opening having an end terminating at the first opening. The elongated first section is disposed within the bracket pocket and is inserted therein and removed therefrom only upon endwise movement of the first section through the first opening. When the first section is accommodated within the bracket pocket, it is substantially impassable with respect to the bracket second opening. The second section is adapted to span the joint when the members are disposed in the predetermined relative position and is in resilient sealing engagement with the side of the other member defining the joint.
