ABSTRACT:
This device creates a joint between two flexible surfaces that can be done and undone with the ease of an ordinary zipper. The device consists of edges on the surfaces to be joined. These edges consist of continuous multiple channels in the form of ridges and grooves and a joining aid in the form of a Flared Y shape tube which when pulled over the surface edges to be joined would apply force in four directions and would force the grooves and ridge channels to fit in each other at the correct angles creating a multiple seal, thereby each of the seals consisting of tightly fitting rod and its corresponding groove. The groove channel openings are offset from each other creating a joint resistance to pull in any direction. The flared Y tube has three tapered edges inside the tube which apply force in separating the three rod/groove sets if the tube is pulled over the joint in the reverse direction.
