发明名称 Loading dock door seal
摘要 A seal system is utilized with flat, rough, and/or ribbed wall surfaces and includes a top dock pad and two substantially parallel side dock pads, which substantially frame a doorway at a loading dock. The dock pads are secured to the wall by a plurality of mounting brackets. The dock pads include a first foam layer coupled to a rear portion of a backing structure. The first foam layer operates to accommodate, or substantially “fill-in”, any surface irregularities of the building wall surface, such as a rough wall texture and rib surfaces, to provide an airtight or substantially airtight seal between the building and the seal structure. The dock pads also include a second foam layer coupled to a front portion of the backing structure. The second foam layer is employed to create an effective seal between the building and a rear portion of a vehicle.
