Loading dock shelter with a rotatable seal

A loading dock shelter mounted adjacent a dock opening in a building wall for use with a truck parked on a driveway adjacent the dock opening, the loading dock shelter comprising:

• a frame assembly having an interior frame lattice disposed about the periphery of the dock opening for supporting at least one seal member adapted to engage the truck, the interior frame lattice formed by a plurality of support members which are spaced apart to permit the movement of air therethrough, and an easily removable outer shell detachably mounted to the support members for selectively covering the frame lattice to prevent the movement of air through the frame lattice and for permitting selective removal independently of the seal member for permitting the movement of air through the frame lattice
• the frame assembly having at least one unitary seal member rotatably mounted thereto for movement about an axis between first and second positions in response to movement of the truck wherein the seal member projects into the path of the incoming truck in the first position and the seal member is adapted to engage a panel of the truck for forming a substantially air-tight seal between the truck and the opening in the second position, the seal member having a flexible outer portion for resiliently and compressibly engaging the panel of the truck for forming the air-tight seal and a rigid inner portion capable of supporting the seal member for movement about the axis.
