ABSTRACT:
A sealing mechanism associated with a dockboard for providing a weather seal for the pit in the loading dock during a loading operation. The sealing mechanism includes a pair of guide tracks mounted on the vertical front face of the dock, and a frame is mounted for sliding movement on the guide tracks and is biased to an upward position. A flexible panel is carried by the frame and extends upwardly and outwardly in a position to be engaged by the rear end of a truck bed as a truck backs toward the loading dock for a loading operation. An operating rod extends upwardly from the frame and is positioned to be engaged by the ramp of the dockboard to thereby enable the panel to follow downward float of the truck bed during a loading operation. Engagement of the panel with the truck bed, along with the engagement of the sides of the panel with bumpers mounted on the loading dock, provide an effective weather seal for the pit area during the loading operation.
