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. After the truck initially engages the seal members, the rearward movement of the truck rotates the seals from the open position to the sealing position in which the seal member is compressed against the outer wall of the truck so that it does not block or otherwise interfere with the normal loading/unloading of the truck.
