ENTRANCE AND EGRESS SYSTEM FOR PROTECTIVE SHELTERS AND GARMENTS

摘要

A method and apparatus is provided for attaching and detaching two panels (10A & 10B), each of which has an opening defined by mating parts of a continuous flexible fastener strip. The panels may be part of protective enclosures, one of which can be portable (a garment or a mobile unit), and which afford a protective environment to persons or things therewithin. A first opening is formed in one panel and a second opening in the other panel, the openings being co-extensive when in abutting position. Primary fasteners, such as zippers (12A & 12B), are attached to each of the openings for repeated opening and closing thereof. Secondary covering fasteners, including flaps (14A & 14B) with fabric hook-latch material, located on the exterior of the panels surround and cover the primary fasteners. The fasteners interengage to fasten the panels together with the openings aligned, thus forming a passage between the interiors of said enclosures.
