Abstract

A snap slit door having at least one panel and a flat closure means used to reate tension in the door panel or panels, such tension acting as the closure force generated by the closure means for the door panel or panels. The flat closure means may be adjustable such that the tension and resulting resistance to opening is variable. Said door panel or panels may be of any pliable material to enable use of the panel or panels without hinges, and further to render the flat closure means operational. The panel or panels may be held in the closed position by any means which will self-release upon the exertion of a requisite pressure differential between the inside and outside of the panel or panels, effectively relieving the pressure differential. One such effective self-releasing closure means is a hook and pile patch arrangement.
