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. The flexible seal member has a seal end adapted to bend and conform to the surface contours of the truck surface in the sealing position so as to form a substantially air-tight seal therewith.
