Abstract
A slide fastener installation is disclosed for use in a sleeping bag, jacket or other article. The slide fastener installation is formed from one continuous slide fastener stringer and one end of the installation is formed by that stringer being looped back on itself. A separating end stop is formed at the other end of the installation and includes a separating end device formed by removing the head portion from a series of coupling elements.
Claims12
A slide fastener comprising a pair of slide fastener stringer tape sections;
- a plurality of slide fastener coupling elements mounted on each stringer tape section, each coupling element having a head portion and a pair of legs extending therefrom;
- at least one slider entrained on the coupling elements of the two stringer tape sections for movement therealong;
- and
- a separating end stop at one end of the slide fastener, the separating end stop including a retaining end stop on one stringer tape section to retain the slider thereon and a separating end device on the other stringer tape section, the separating end device including a plurality of substantially undeformed severed pairs of leg portions of coupling elements from which the head portions have been removed and a thermoplastic film folded over the severed leg portions and bonded to the opposite sides of the other stringer tape section, said thermoplastic film reinforcing the other stringer tape section and severed leg portions and being sufficiently thin to permit movement of the separating end device through the slider.

A sleeping bag comprising
- an upper and a lower bag half, each of generally rectangular shape and filled with an appropriate insulating material, the two bag halves being joined along one common longitudinal edge,
- a slide fastener stringer section extending along the opposite longitudinal and bottom edge of each of the bag halves, each of the stringer sections including a continuous mounting tape having a series of spaced, symmetrical coupling elements mounted along one edge thereof,
- a pair of sliders entrained on the two stringer sections, the sliders being oriented in opposite directions to engage and disengage the coupling elements of the stringer sections from opposite directions, and
- an end stop formed at the end of the bottom edge of the bag adjacent the common longitudinal edge, the stringer sections being each a part of one continuous stringer with the end stop being formed by the one continuous stringer being looped back on itself.
