  • Patent number: 6425214
    Abstract: A sealing device for engaging the surface of a vehicle parked adjacent a structure and which is automatically actuated in response to the approach or departure of the vehicle. A seal member is supported by a pivoting frame which is mountable to the structure. The pivoting frame is moveable between an engaged position in which the seal is positioned to engage the vehicle surface and a released position in which the seal is spaced away from the vehicle surface. A pivoting actuating member is mountable to the structure and engages the frame. The actuating member is adapted to be responsive to movement of the vehicle, so that the frame having the attached seal member moves toward the engaged position as the vehicle approaches the structure. Accordingly, the seal member seals the interior of the cargo vehicle as well as the interior of the structure from the ingress of wind, water and other contaminants in order to maintain a safer work environment.

  • Patent number: 5953868
    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.

  • Patent number: 5622016
    Abstract: 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.
