ABSTRACT:
An improved dock shelter comprising a pair of side panels and a top panel which are hinged to the dock and border a doorway in the dock. The panels are each biased to a storage position where the panel extends laterally outward from the dock. The panels are pivoted inwardly from the storage position to an operative sealing position by inflatable bags which are operably connected to the panels. A blower mounted above the doorway operates through a duct system to inflate the bags and pivot the panels into sealing engagement with the sides and top of a truck parked in front of the dock. When the loading operation is completed, operation of the blower is discontinued and the biasing mechanism acts to return the panels to the storage position. Corner panels are carried by the top panel and are mounted for flatwise sliding movement relative to the respective side panels. The corner panels provide an effective seal between the upper ends of the side panels and the top panel regardless of the angular inclination of the top panel.
