Abstract

Abstract A SLEEPING BAG CONSTRUCTION WHICH MAY BE USED TO PROVIDE EITHER A SINGLE SLEEPING BAG IN WHICH THE NUMBER OF WARMTH-PROVIDING LAYERS CAN BE VARIED, A DOUBLE SLEEPING BAG FOR USE BY TWO PERSONS, OR TWO SEPARATE SINGLE SLEEPING BAGS. THE SLEEPING BAG INCLUDES A PAIR OF GENERALLY RECTANGULAR BLANKETS OF APPROXIMATELY THE SAME SIZE. A FIRST, OR OUTER, BLANKET IS PROVIDED WITH A PAIR OF ROWS OF ZIPPER ELEMENTS OR TEETH WHICH EXTEND CONTINUOUSLY ALONG ONE SIDE OF THE OUTER BLANKET AND ALONG ONE-HALF OF AN ADJACENT SIDE. A SECOND PAIR OF ROWS OF ZIPPER ELEMENTS EXTENDS ALONG THE SIDE OF THE OUTER BLANKET OPPOSITE THE FIRST SIDE AND ALONG THE OTHER HALF OF THE ADJACENT SIDE. SIMILARLY, THE SECOND, OR INNER, BLANKET IS PROVIDED WITH A ROW OF ZIPPER ELEMENTS EXTENDING ALONG ONE SIDE AND ALONG ONE-HALF OF AN ADJACENT SIDE, AND A SECOND ROW OF ZIPPER ELEMENTS EXTENDING ALONG THE OPPOSITE SIDE AND ALONG THE OTHER HALF OF THE ADJACENT SIDE. THE INNER BLANKET MAY BE PLACED ON TOP OF THE OUTER BLANKET, AND BOTH BLANKETS MAY BE FOLDED UPON THEMSELVES TO FORM FOUR BLANKET LAYERS. EACH ZIPPER ROW ON THE INNER BLANKET IS ENGAGEABLE WITH ONE OF THE INNER ZIPPER ROWS ON THE OUTER BLANKET, AND THE TWO OUTER ZIPPER ROWS OF THE OUTER BLANKET CAN BE JOINED TO PROVIDE A SINGLE SLEEPING BAG IN WHICH EITHER ONE, TWO, OR THREE LAYERS MAY BE USED TO WARM THE PERSON SLEEPLING IN THE BAG. IF THE OUTER ZIPPER ROWS ARE UNFASTENED, THE TWO BLANKETS CAN BE UNFOLDED TO PROVIDE A DOUBLE SLEEPING BAG IN WHICH THE INNER BLANKET COVERS THE TWO SLEEPERS. FINALLY, THE INNER BLANKET MAY BE UNFASTENED FROM THE OUTER BLANKET, AND TWO SLEEPING BAGS MAY BE PROVIDED BY JOINING THE TWO OUTER ZIPPER ROWS OF THE OUTER BLANKET AND THE TWO ROWS OF THE INNER BLANKET.
