Portable shelter system

Abstract

A portable shelter system is constructed from two portable shelters. Each portable shelter is provided with an enclosure having a front wall configured with a door and a rear wall configured with an opening. The opening of each rear wall is fitted with first and second zippers about the perimeter of the opening. A second door fitted with a mating zipper is reversibly connected to the first zipper. A sleeve having opposing first and second perimeter edges is fitted with mating zippers that connect to the second zippers of each opening when the rear walls of the two portable shelters are adjacent to and spaced from one another.

1 . A method of forming a portable shelter system comprising: 
 providing first and second enclosures, wherein each enclosure has a plurality of side walls, each enclosure comprising: 
 a first side wall configured with a first opening and a door mateable with the first opening;  
 a second side wall opposite the first side wall, the second side wall configured with a second opening having a perimeter edge, first and second reversible mechanical connecting mechanisms being attached to the second side wall adjacent the perimeter edge; and  
 a second door configured for connection to the first reversible mechanical connecting mechanism;  
   providing a sleeve having a circumference and spaced first and second circumferential edges, each of the first and second circumferential edges comprising third and fourth reversible mechanical connecting mechanisms, respectively;    positioning the second wall of the first enclosure adjacent to and spaced from the second wall of the second enclosure;    connecting the third reversible mechanical connecting mechanism of the first sleeve circumferential edge to the second connecting mechanism of the first enclosure; and    connecting the fourth connecting mechanism of the second sleeve circumferential edge to the second connecting mechanism of the second enclosure.    
   
   
       2 . The method of  claim 1  wherein the step of providing first and second enclosures further comprises positioning the first connecting mechanism facing an interior of the enclosure and positioning the second connecting mechanism facing an exterior of the enclosure.  
   
   
       3 . A portable shelter system comprising: 
 a first enclosure defined by a plurality of walls comprising a front wall, a rear wall and interconnected side walls, the rear wall configured to define an opening having a perimeter edge, wherein the perimeter edge comprises first and second reversible mechanical connecting mechanisms;    a second enclosure defined by a plurality of walls comprising a front wall, a rear wall and interconnected side walls, the rear wall configured to define an opening having a perimeter edge, wherein the perimeter edge comprises first and second reversible mechanical connecting mechanisms, the rear wall of the second enclosure positioned adjacent to and spaced from the rear wall of the first enclosure; and    a sleeve having spaced first and second circumferential edges, the first and second circumferential edges comprising third and fourth reversible mechanical connecting mechanisms, respectively, wherein the third connecting mechanism is engaged with the second connecting mechanism of the first enclosure and wherein the fourth connecting mechanism is engaged with the second connecting mechanism of the second enclosure.    
   
   
       4 . The portable shelter system of  claim 3  wherein the rear wall of each of the first and second enclosure comprises a door having a perimeter mechanical connecting mechanism, the perimeter connecting mechanism engaged with the first connecting mechanism.  
   
   
       5 . The portable shelter system of  claim 3  wherein the opening of each of the first and second enclosures comprises a diameter smaller than that of the respective rear wall.  
   
   
       6 . The portable shelter system of  claim 3  wherein the opening of each of the first and second enclosures comprises a generally circular opening.  
   
   
       7 . The portable shelter system of  claim 3  wherein the opening of each of the first and second enclosures comprises a perimeter shape different than that of the respective rear wall.  
   
   
       8 . A portable shelter system comprising: 
 a first and a second enclosure, each enclosure defined by a plurality of walls, each wall having a height and a width;    an opening in a first wall of the first enclosure, the opening having a dimension less than the height and width of the first wall;    an opening in a first wall of the second enclosure that is complementary to the opening in the first wall of the first enclosure, wherein the opening in the first wall of the second enclosure has a dimension less than the height and width of the second enclosure;    a first sleeve having spaced first and second circumferential edges reversibly connected between the first and second enclosures at the respective openings; and    fastening means for mechanically removably connecting the spaced first and second circumferential edges of the first sleeve to the first and second enclosures, respectively.    
   
   
       9 . The portable shelter system of  claim 8  and further comprising: 
 an opening in second wall of the first enclosure;    a third enclosure defined by a plurality of walls and having a height and a width;    an opening in a first wall of the third enclosure that is complementary to the opening in the second wall of the first enclosure, wherein the opening in the first wall of the third enclosure has a dimension less than the height and width of the third enclosure;    a second sleeve having spaced first and second circumferential edges reversibly connected between the first and third enclosures at the respective openings; and    fastening means for mechanically removably connecting the spaced first and second circumferential edges of the second sleeve to the first and third enclosures, respectively.    
   
   
       10 . The portable shelter system of  claim 8  and further comprising a door having perimeter fastening means for effectively closing off the first opening by mechanically engaging the door with a perimeter portion of the first opening.  
   
   
       11 . The portable shelter system of  claim 8  wherein the opening of each of the first and second enclosures comprises a generally circular opening.  
   
   
       12 . The portable shelter system of  claim 8  wherein the opening of each of the first and second enclosures comprises a perimeter shape different than that of the respective first walls.
