       2 . A collapsible enclosure is provided comprising:
 a plurality of structural support beams;   a first hub having a plurality of first attachment means to which one end of said structural support beams are attached;   a second hub having a plurality of second attachment means and pressure plate positioned below said second attachment means;   a plurality of strut members having inner and outer ends the outer ends being pivotally attached to a structural support beam and the inner ends being pivotally attached to a second attachment means of said second hub such that when engaging said pressure plates said struts are forced outward from said second hub and against said structural support beams;   a cover disposed upon and traversing between the structural support beams having a top portion and a bottom portion, the top portion having means for receiving the plurality of structural support beams, the bottom portion having adapters for receiving the ends of the plurality of structural support beams, said covering having one or more openings and one or more flaps to secure said one or more openings.   
   
   
       3 . A collapsible enclosure comprising:
 a plurality of structural support beams;   a hub having an attachment member to which one end of said structural support beams are attached and a rotating member for engaging and forcing said plurality of structural supports beams outward from said hub;   a cover disposed upon and traversing between said structural support beams having a top portion and a bottom portion, said top portion having means for receiving said plurality of structural support beams, said bottom portion having adapters for receiving said ends of said plurality of structural support beams, said cover having one or more openings and one or more flaps to secure said one or more openings.   
   
   
       4 . The collapsible enclosure according to  claim 1  wherein the pressure plates of the hub may be angled downward from the plane of said hub not less than 5 degrees. 
   
   
       5 . The collapsible enclosure according to  claim 1  wherein the pressure plates of the hub may be angled downward from the plane of said hub not more than 85 degrees. 
   
   
       6 . The collapsible enclosure according to  claim 2  wherein the pressure plates of the hub may be angled downward from the plane of said hub not less than 5 degrees. 
   
   
       7 . The collapsible enclosure according to  claim 2  wherein the pressure plates of the hub may be angled downward from the plane of said hub not more than 60 degrees. 
   
   
       8 . The collapsible enclosure according to  claim 3  wherein the pressure plates of the hub may be angled downward from the plane of said hub not less than 5 degrees. 
   
   
       9 . The collapsible enclosure according to  claim 3  wherein the pressure plates of the hub may be angled downward from the plane of said hub not more than 85 degrees. 
   
   
       10 . The collapsible enclosure according to  claim 3  further comprising a handle positioned below said pressure plates for gripping and rotating said rotating member into position engaging and forcing said plurality of structural supports beams outward from said hub. 
   
   
       11 . The collapsible enclosure according to  claim 3  further comprising a rotation stop on said pressure plates to prevent over rotation of said rotating member. 
   
   
       12 . The collapsible enclosure according to  claim 1  may further comprise hinged joints on said structural supports beams between their ends so that they may be folded when in the enclosure is in the collapsed configuration. 
   
   
       13 . The collapsible enclosure according to  claim 2  may further comprise hinged joints on said structural supports beams between their ends so that they may be folded when in the enclosure is in the collapsed configuration. 
   
   
       14 . The collapsible enclosure according to  claim 3  may further comprise hinged joints on said structural supports beams between their ends so that they may be folded when in the enclosure is in the collapsed configuration. 
   
   
       15 . The collapsible enclosure according to  claim 2  wherein said inner ends of said strut members when said enclosure is in the constructed configuration exerts a downward bias against said pressure plates of said second hub maintaining the structure in its constructed configuration. 
   
   
       16 . The collapsible enclosure according to  claim 2  wherein the downward pressure on said first hub causes the inner ends of said strut members to move below the outer ends of said strut members thereby overcoming the downward bias on said second hub and allowing said enclosure to collapse. 
   
   
       17 . The collapsible enclosure according to  claim 1  wherein said adapters for receiving the other ends of said structural support beams are flexible pockets. 
   
   
       18 . The collapsible enclosure according to  claim 2  wherein said adapters for receiving the other ends of said structural support beams are flexible pockets. 
   
   
       19 . The collapsible enclosure according to  claim 3  wherein said adapters for receiving the other ends of said structural support beams are flexible pockets. 
   
   
       20 . The collapsible enclosure according to  claim 2  wherein said second hub comprising said pressure plates further comprises a locking structure for mechanically locking said strut members in position maintaining the downward bias toward the pressure plates by the strut members. 
   
   
       21 . The collapsible enclosure according to  claim 1  wherein said cover further comprises straps for securing said enclosure to a surface. 
   
   
       22 . The collapsible enclosure according to  claim 2  wherein said cover further comprises straps for securing said enclosure to a surface.
