Magnetic sleeping bag

Abstract

A sleeping bag for providing easy and carefree exit and entry for a user, for providing comfort for the user by having an ability to extend appendages of the user out of the sleeping bag without having to open the sleeping bag in its entirety, and for providing a no-fail engage or disengage exit for potential emergency situations. The sleeping bag includes a lower layer, an upper layer, and a magnetic closure. The upper layer overlies the lower layer so as to form a user space therebetween for the user. The magnetic closure replaceably attaches a portion of the upper layer to a corresponding portion of the lower layer and provides the easy and carefree exit and entry for the user, provides comfort for the user by having an ability to extend appendages of the user out of the sleeping bag without having to open the sleeping bag in its entirety, and provides a no-fail engage/disengage exit for potential emergency situations.

The invention claimed is: 
     
         1 . A sleeping bag for providing easy and carefree exit and entry for a user, for providing comfort for the user by having an ability to selectively extend appendages of the user out of the insulated sleeping bag without having to open the sleeping bag in its entirety, and for providing a no-fail engage or disengage exit for potential emergency situations, comprising:
 a) a lower layer;   b) an upper layer; and   c) a magnetic closure;   wherein said upper layer overlies said lower layer so as to form a user space therebetween for a user; and   wherein said magnetic closure replaceably attaches a portion of said upper layer to a corresponding portion of said lower layer for providing the easy and the carefree exit and the entry for the user, for providing the comfort for the user by having the ability to selectively extend the appendages of the user out of the sleeping bag without having to open the sleeping bag in its entirety, and for providing the no-fail engage/disengage exit for the potential emergency situations.   
     
     
         2 . The sleeping bag of  claim 1 , wherein said lower layer is waterproof for protection if the support surface is wet. 
     
     
         3 . The sleeping bag of  claim 2 , wherein said perimeter of said lower layer is generally rectangular-shaped, and as such, has:
 a) a pair of long edges; and   b) a pair of short edges.   
     
     
         4 . The sleeping bag of  claim 1 , wherein said upper layer overlies said lower layer to define said user space therebetween. 
     
     
         5 . The sleeping bag of  claim 1 , wherein said upper layer overlies said lower layer and a remaining portion of said perimeter of said upper layer is affixed to said corresponding remaining portion of said perimeter of said lower layer. 
     
     
         6 . The sleeping bag of  claim 5 , wherein said portion of said perimeter of said upper layer and said corresponding portion of said perimeter of said lower layer are normally open for the user, but selectively close by said magnetic closure. 
     
     
         7 . The sleeping bag of  claim 6 , wherein said corresponding portion of said perimeter of said lower layer includes one short edge of said perimeter of said lower layer and an adjacent long edge of said perimeter of said lower layer. 
     
     
         8 . The sleeping bag of  claim 1 , wherein said magnetic closure comprises a pair of material strips. 
     
     
         9 . The sleeping bag of  claim 8 , wherein each material strip of said magnetic closure forms a generally L-shape. 
     
     
         10 . The sleeping bag of  claim 8 , wherein each material strip of said magnetic closure is flat. 
     
     
         11 . The sleeping bag of  claim 8 , wherein one material strip of said magnetic closure extends along said corresponding portion of said lower layer, 
     
     
         12 . The sleeping bag of  claim 11 , wherein the other material strip of said magnetic closure extends along said portion of said upper layer, in alignment with said one material strip of said magnetic closure. 
     
     
         13 . The sleeping bag of  claim 12 , wherein said magnetic closure comprises a pair of a plurality of magnets. 
     
     
         14 . The sleeping bag of  claim 13 , wherein said pair of said plurality of magnets of said magnetic closure are disk-shaped. 
     
     
         15 . The sleeping bag of  claim 13 , wherein one plurality of magnets of said magnetic closure extend along said one material strip of said magnetic closure and are spaced thereapart. 
     
     
         16 . The sleeping bag of  claim 15 , wherein said one plurality of magnets of said magnetic closure are spaced apart from each other a distance equal to a distance that the other plurality of magnets of said magnetic closure are spaced apart from each other for proper engagement when said magnetic closure is closed. 
     
     
         17 . The sleeping bag of  claim 15 , wherein adjacent ones of each of said pair of plurality of magnets of said magnetic closure have opposite polarities for assuring a uniform closure of said magnetic closure; and
 wherein one magnet is positive and said magnet directly adjacent thereto is negative.   
     
     
         18 . The sleeping bag of  claim 17 , wherein a distance between adjacent ones of said pair of plurality of magnets of said magnetic closure is proportional to magnetic strength of said pair of a plurality of magnets of said magnetic closure for preventing adjacent ones of said pair of plurality of magnets of said magnetic closure from being attracted to each other, especially because of said opposite polarities of said adjacent ones of said pair of plurality of magnets of said magnetic closure. 
     
     
         19 . The sleeping bag of  claim 18 , wherein said magnetic closure comprises stitches. 
     
     
         20 . The sleeping bag of  claim 19 , wherein said stitches of said magnetic closure hold said one material strip of said magnetic closure to said corresponding portion of said lower layer and hold the other material strip of said magnetic closure to said portion of said upper layer.
