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 loading dock shelter having rotating seal members is provided for forming a relatively air-tight seal between the dock opening and a truck so as to prevent air movement between the inside and the outside of the building during loading and unloading operations. The loading dock shelter has a frame assembly rigidly attached to the periphery of the dock opening and seal members rotatably mounted to the frame assembly on either side of the dock opening so that the truck may fit therebetween and form a seal between the exterior walls of the truck and the seal member. The seal members are rotatably movable between a first (open) position and a second (sealing) position in response to the movement of the truck into and out of the loading dock. In the first position, the seal members project into the path of the truck so that the truck engages the seal members as it backs into the loading dock.

Abstract: A loading dock shelter having a rotating seal member is provided for forming a relatively air-tight seal between the dock opening and the truck to prevent the movement of air between the inside and outside of the building during the loading and unloading operation. The seal members are rotatably mounted to the frame assembly for rotation between a first (open) position and a second (sealing) position in response to the movement of the truck into and out of the loading dock. In the first position, the seal member is spaced outwardly from the wall and the loading dock so that it does not interfere with the normal operation of the loading dock and so that it projects into the path of the truck for engaging the truck as the truck backs into the loading dock.
