ABSTRACT:
A lightweight collapsible tent structure is disclosed which can be folded into a compact "U-shaped" package readily nested around a conventional hiker's back pack thereby facilitating easy transportation through difficult terrain. This tent structure comprises a rectangular tent support frame made of aluminum or plastic tubing which has the ability of being quickly erected from its collapsed state by merely straightening its hinged joints. A rectangular box-like tent fabricated from flame-retardant, water-impervious, nylon material strapped to the tubular framework unfolds into its functional configuration when the frame structure is erected. This tent shelter permits easy attachment to a second unit thus expanding its capacity to accommodate additional occupants.
