Patent number: 10563805Abstract: A sealing assembly has an expansion band having an arcuate band portion and a pair of threaded end portions formed at opposing ends of the arcuate band, in which the arcuate band and threaded end portions are monolithically formed as a single piece. Fixed within respective threaded end portions are a pair of oppositely threaded nuts adapted to receive a bolt having correspondingly oppositely threaded ends. Rotation of the bolt causes the threaded end portions to be simultaneously driven apart or drawn toward one another (depending on the rotation direction of the bolt) to thereby expand or contract the overall outer profile of the arcuate band portion. The monolithically formed expansion band may be made of an inexpensive, non-rusting material such as nylon 66, and glass fibers and/or additives may be employed to impart strength and flexibility.Type: GrantFiled: March 29, 2017Date of Patent: February 18, 2020Assignee: Press-Seal CorporationInventors: James W. Skinner, Graham E. Blackwood, Katherine A. Bergfeld, Michael R. Miller, John R. Kaczmarczyk

Publication number: 20150082704Abstract: A roll-up door seal arrangement includes side seals, an upper seal and a lower seal to completely seal the periphery of a roll-up door when the door is in a closed position. The seals are sized and adapted to assemble to a standard roll-up door frame without a separate or dedicated frame structure. The seals provide redundant sealing surfaces, positioned to cooperate with both the door and door frame, which ensure an effective and durable fluid tight seal between the cargo space enclosed by the roll-up door and the ambient environment. The seal may be produced by extrusion from a flexible, weather resistant material such as EPDM, thereby providing a low cost solution for sealing roll-up doors having industry standard door frame constructions. The seal is firmly engageable with the door frame, such that the seal may be installed with little or no use of secondary fixation.Type: ApplicationFiled: September 30, 2014Publication date: March 26, 2015Inventors: Jimmy D. Gamble, Robert R. Slocum, Graham E. Blackwood, Katherine A. Bergfeld

Publication number: 20140352227Abstract: A one-piece seal is used between the rear doors of a semi-trailer truck and the rear frame of the truck, the seal having a good compression set resistance. The seal is made from multiple extrusion members that are fused, welded, or otherwise integrally, monolithically connected at corner joints to form a central opening. The extrusion members have a sealing profile, or cross-section, that allows for the compression and deflection of a pair of sealing lobes to create inner and outer seals, respectively, between the trailer frame and the door structure at the rear of a semi-trailer truck, as well as between the doors themselves.Type: ApplicationFiled: August 15, 2014Publication date: December 4, 2014Applicant: Press-Seal Gasket CorporationInventors: Andrew J. Happel, Myron S. Worley, Katherine A. Bergfeld
