Abstract: A loading dock shelter having a resilient and flexible seal assembly is provided for forming a substantially air-tight seal between the dock opening and the truck. The seal assembly comprises a support or panel member which is adapted to attach to the loading dock frame and to support a seal member. The seal member has a substantially hook-shaped cross-section adapted to hookably engage the incoming truck and is capable of resiliently flexing between a hook-shaped cross-section in the disengaged position and a substantially straight cross-section in the sealing position in response to the truck. The hook-shaped cross section permits the seal member to sealably engage the interior wall of the truck, and, in the alternative, will seal against the peripheral edge of the truck, or the exterior wall of the truck depending on the size and position of the truck.

Abstract: A seal assembly, which minimizes or eliminates infiltration of rain water along the roof of a truck parked in a loading dock, generally comprises a downwardly inclined roof panel which extends outwardly from the building wall and collects the water. A gutter member, supported by and disposed along the length of the roof panel, collects water runoff from the building walls and the roof panel and channels the water away from the center of the door opening and towards either side of the loading dock opening. The seal assembly also comprises a seal member mounted to the roof panel and/or the gutter member so that it generally hangs into the upper portion of the door opening and engages the top portion of the truck so as to sealably engage the truck roof and form a water blocking barrier, thereby minimizing or eliminating infiltration of rain water along the truck roof.

Abstract: A dock shelter adapted for mounting to a wall about an opening in the wall includes a plurality of coupled outer panels comprised of molded plastic. The plastic outer panels include a pair of roof sections as well as left and right lateral sections each coupled to a respective distal end of a roof section. Each lateral section includes respective pairs of upper and lower side panels coupled together in a telescoping manner to allow the height of the dock shelter to be fixed as desired over a range of values. Similarly, the roof sections are coupled together by means of a center roof connector cap in a telescoping manner to allow for adjustment of the width of the dock shelter. The telescoping coupling arrangement between the various dock shelter structural members allows the dock shelter to be used with a wide range of wall opening sizes.

Abstract: A seal disposed about the periphery of an opening such as a warehouse door includes an inflatable head bag and a pair of facing inflatable side bags. The head and side bags are each comprised of a plurality of serially coupled, elongated, aligned pleated sections which are separated by apertured baffles for regulating air flow between adjacent pleated sections. A source of air under pressure such as a blower directs air into an upper head bag which, in turn, directs the air flow into the facing side bags via respective duct arrangements coupling the head bag to the side bags. Under pressure, the head and side bags expand toward the center of the opening to enclose in a sealed manner an object such as a loading vehicle positioned within the opening.

Abstract: A loading dock shelter of the pad type having L-shaped configuration, which, in normal operation provides a wrap-around type of engagement with the rear end of trucks backed into operative engagement with the loading dock shelter.
