Abstract

A loading dock shelter with hinge gap closure wherein reinforced side curtains seal corner/hinge areas, as a truck/trailer is backed into a loading dock, to thereby form a protective weather seal. Hinge gap closures having side curtains for right and left portions of the shelter are each adapted to set the curtains parallel to the door of the dock in the normal position, when the dock is not in use, thereby protecting the door from inclement weather, etc. When a trailer is moved into the dock, reverse mobility of the vehicle is such as to cause the side curtains to be deflected from normal inoperative position, to extend them along the side of the respective trailer swing doors, whereby a collapsible wedge on the extreme extension of each curtain encompasses the gas created by the truck and its swing door, in sealing contact, preparatory to and during loading and off-loading. An articulated hinge functions to close against the side frame of the shelter when not in use and when in use to extend itself arcuately inward from the side frame of the shelter toward the trailer body and its swing door. Its attached side curtain is extended inwardly to seal the gap between trailer and shelter. A coactive fabric filler of the assembly is also provided to seal any gap remaining between hinge leaf elements and shelter side wall.
