| 141 | Storage terminal shelter, including side curtain assembly for truck/trailer hinge gap closure | US994747 | 1992-12-22 | US5341613A | 1994-08-30 | Thomas R. Brockman; Mark Dillon |
| 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. | ||||||

| 147 | Dock shelter | US791985 | 1985-10-28 | US4671029A | 1987-06-09 | David E. Bennett, deceased; Mark A. Bennett |
| 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. | ||||||

| 155 | Sealing device | US626944 | 1975-10-29 | US4020607A | 1977-05-03 | Leon Hans-Hother Bjervig |
| The sealing device disclosed herein is designed for providing an air tight seal between a door casing and the sides of a vehicle positioned adjacent the casing. It comprises an elongated rigid angular profile having flanges which define a channel-shaped space therebetween and a resilient and collapsible pad structure fastened in the channel-shaped space between the flanges of the angular profile. The pad structure includes a collapsible spongy material enclosed in an air tight envelope, and the interior of the pad communicates with a vacuum source. In its distended position, the material inside the pad structure will cause the pad to expand a considerable distance beyond the flanges of the angular profile so as to abut the sides of the vehicle thereby providing an air tight seal. When a vacuum is applied to the collapsible material, the pad structure will collapse and be retracted almost completely into the channel-shaped space between the flanges of the profile. The sealing device is then in its inoperative position leaving a free space between the profile and the walls of the vehicle. | ||||||

| 160 | Inflatable canopy | US26573472 | 1972-06-23 | US3816867A | 1974-06-18 | SHIRZAD P; PENINSULA P; REIDT D |
| An inflatable canopy which is primarily intended to be utilized in at least partially enclosing the space between an aircraft loading bridge and an aircarft can be constructed utilizing an inflatable member divided up into interconnected internal sections so that when the member is inflated, the inflatable member will flare outwardly from an essentially flat folded position to an inflated position corresponding to the shape of an aircraft hull. A frame means for supporting the sections of the inflatable member in both the folded and inflated positions is provided along with a counterweight folding means for moving the canopy from the inflated position to the folded position. The inflatable member is preferably mounted on a frame body pivotally connected to an aircraft loading bridge. This frame body may be spaced from the bridge; the space between it and the bridge may be enclosed by a bellows.
