Sleeping Bag with Variable Magnetic Closure Positions

Abstract

A sleeping bag with variable magnetic closure positions includes an inner shell and an outer shell enclosing a filler material, forming a sleeping space. An opening for accessing the sleeping space is adjacent a first edge and a second edge. The first edge and the second edge are overlapping and having aligning magnetic bodies. The sleeping bag also has magnetic bodies arranged to attach to the first edge and to the second edge. When the first edge and the second edge are coupled together, an enlarged sleeping space is created. When the first edge and the second edge are overlapping so that magnetic bodies on the first edge and the second edge are coupled to magnetic bodies on the sleeping bag, a reduced sleeping space is created.

What is claimed is: 
     
         1 . A magnetic closure sleeping bag having multiple closure settings, the sleeping bag comprising:
 an inner shell and an outer shell enclosing a filler material, the inner shell and the outer together defining a sleeping space within the sleeping bag;   the sleeping bag defining an opening for accessing the sleeping space, the opening adjacent a first edge and a second edge of the sleeping bag;   the first edge and the second edge having aligning first magnetic bodies;   the sleeping bag having second magnetic bodies that align with the first magnetic bodies;   wherein an enlarged sleeping space is created when first edge and the second edge are coupled together by the first magnetic bodies; and   wherein a reduced sleeping space is created when the first magnetic bodies are coupled to the second magnetic bodies.   
     
     
         2 . The sleeping bag of  claim 1  wherein the first magnetic bodies and the second magnetic bodies are enclosed by the inner shell and the outer shell. 
     
     
         3 . The sleeping bag of  claim 1  wherein the filler material separates the first magnetic bodies and the second magnetic bodies from the sleeping space. 
     
     
         4 . The sleeping bag of  claim 1  wherein the first magnetic bodies and the second magnetic bodies are located between the outer shell and the filler material. 
     
     
         5 . The sleeping bag of  claim 1  wherein a baffle is created when the first magnetic bodies are coupled to the second magnetic bodies. 
     
     
         6 . The sleeping bag of  claim 1  further comprising a gusset coupled to the first edge and the second edge. 
     
     
         7 . The sleeping bag of  claim 1  further comprising a gusset opposite the opening. 
     
     
         8 . The sleeping bag of  claim 1  wherein the second magnetic bodies provide multiple complimentary positions, allowing the first magnetic bodies coupling to the second magnetic bodies to create multiple sizes of sleeping spaces. 
     
     
         9 . The sleeping bag of  claim 1 , further comprising a sleeping pad adjacent the sleeping space. 
     
     
         10 . The sleeping bag of  claim 1  wherein the second magnetic bodies are arranged in rows. 
     
     
         11 . The sleeping bag of  claim 1  wherein the sleeping bag is a mummy-type sleeping bag. 
     
     
         12 . The sleeping bag of  claim 1  further comprising a closure flap adjacent the opening. 
     
     
         13 . The sleeping bag of  claim 1  wherein the sleeping bag is rectangular in plan view. 
     
     
         14 . A sleeping bag magnetically closeable in multiple positions, the sleeping bag comprising:
 an inner shell and an outer shell enclosing a filler material, the inner shell and the outer together defining a sleeping space within the sleeping bag;   an opening adjacent the sleeping space, the opening having a first edge and a second edge configured to overlap, thereby adjusting the size of the opening.   the first edge and the second edge joined by a gusset;   the opening having first magnetic bodies disposed along the first edge and the second edge;   the sleeping bag having second magnetic bodies disposed in the sleeping bag, the second magnetic bodies arranged complimentary to the first magnetic bodies;   wherein the first edge and the second edge may be magnetically coupled together to create an enlarged sleeping space; and   wherein a the first edge and the second edge may be magnetically coupled to the outer shell, in an overlapping configuration, to create a reduced sleeping space.   
     
     
         15 . The sleeping bag of  claim 14  wherein the first magnetic bodies and the second magnetic bodies are enclosed by the inner shell and the outer shell. 
     
     
         16 . The sleeping bag of  claim 14  further comprising a baffle formed when the first edge and the second edge are overlapping. 
     
     
         17 . The sleeping bag of  claim 14  wherein the second magnetic bodies are arranged in rows. 
     
     
         18 . The sleeping bag of  claim 1  wherein the sleeping bag is a mummy-type sleeping bag. 
     
     
         19 . The sleeping bag of  claim 1  further comprising a closure flap adjacent the opening. 
     
     
         20 . The sleeping bag of  claim 1  wherein the sleeping bag is rectangular in plan view.
