A loading dock shelter with hinge gap closure wherein reinforced side curtains seal corner/hinge areas, as a truck/trailer is backed into the loading dock, to thereby form a protective weather seal for the dock. Excessive pull on opposed side curtains is compensated by a pair of spring-loaded hinge assemblies, connecting the respective curtains to each shelter side frame of the front walls. 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 closed position, when the dock is not in use. When a trailer is backed into the dock, reverse mobility of the vehicle causes the side curtains to be forcibly deflected from their normal aligned and inoperative position, to extend them along the inside of respective trailer swing doors when open, whereupon a collapsible wedge on the extreme end of each side curtain encompasses and plugs the dock gap, created by the truck and its swing doors, preparatory to and during loading and off-loading. Respective side curtain hinges function to close in transverse extension of the side frame of the shelter when it is not in use. When in use, the hinges extend themselves arcuately outward from the side frame of the shelter toward the trailer body and its exposed swing door. Each attached side curtain is thus extended inwardly to seal the dock gap between open trailer doors and shelter. An elongated collapsible pad on the free end of the side curtain, is coactively engaged by the side wall of the vehicle, its door hinge and the open door of the service vehicle.
