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.

Loading dock seal assembly

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. In one embodiment, the seal member comprises a fabric curtain which is suspended into the path of the incoming truck and drapes over the truck roof to form a seal therewith. In another embodiment, the seal member comprises a resilient, compressible and deformable seal pad, pivotally suspended from the roof panel and/or the gutter member, into the path of the incoming truck and for engaging the roof and/or the top rear peripheral edges of the truck and thereby form a barrier to rain, snow, air and the like.
