Apparatus for hunting blind with enlarged access and force generating structure

Abstract

A method and apparatus for constructing a blind structure, such as a hunting blind. Two or more hub structures are formed, each with a hub and at least one and preferably four rods or support arms. The two hub structures are connected together. An expandable joint, such as an extension rod or extension arm, is positioned and connected so that each hub structure forces a hub to contact a corresponding panel. It is possible to force the panel into a concave orientation, such as in an outward direction from an interior to an outside of the blind structure.

What is claimed is: 
     
         1 . A blind structure, comprising:
 a first panel, a first hub structure having a first hub and at least one first support arm near the first panel, a second panel, a second hub structure having a second hub and at least one second arm near the second panel, the first hub structure connected to the second hub structure, and an expansion arm attaching the first hub structure to the second hub structure and forcing the first hub to contact the first panel and forcing the second hub to contact the second panel.   
     
     
         2 . The blind structure according to  claim 1 , wherein the expansion arm has an adjustable length and is attachable to the first panel and the second panel. 
     
     
         3 . The blind structure according to  claim 1 , wherein the first hub is forced toward and contacts a first inside surface of the first panel and the second hub is forced toward and contacts a second inside surface of the second panel. 
     
     
         4 . The blind structure according to  claim 1 , further comprising a rear panel connected to the first panel and the second panel. 
     
     
         5 . The blind structure according to  claim 1 , further comprising a rod pocket attached to the first panel and the at least one first arm detachably mounted within the rod pocket. 
     
     
         6 . The blind structure according to  claim 1 , wherein positioning the expansion arm transforms the first panel and the second panel into a force-loaded taut condition. 
     
     
         7 . The blind structure according to  claim 1 , further comprising the first hub structure having four first support arms each connected to the first hub and the second hub structure having four second support arms each connected to the second hub. 
     
     
         8 . The blind structure according to  claim 1 , wherein the expansion arm is adjustable and moveable to transition the at least one first support arm and the at least one second support arm each from a symmetrical condition to an asymmetrical condition. 
     
     
         9 . The blind structure according to  claim 1 , wherein the expansion arm loads a first force in the first hub and maintains the first panel taut and loads a second force in the second hub and maintains the second panel taut. 
     
     
         10 . A blind structure, comprising:
 a first hub structure having a first hub and at least one first support arm near a first panel, a second hub structure having a second hub and at least one second support arm near a second panel, and an expansion arm releasably attaching the first hub structure to the second hub structure and forcing the first hub to contact the first panel and forcing the second hub to contact the second panel.   
     
     
         11 . The blind structure according to  claim 10 , wherein the expansion arm has an adjustable length. 
     
     
         12 . The blind structure according to  claim 10 , further comprising a rear panel connected to the first panel and the second panel. 
     
     
         13 . The blind structure according to  claim 10 , further comprising a rod pocket attached to the first panel and the at least one first arm detachably mounted within the rod pocket. 
     
     
         14 . The blind structure according to  claim 10 , wherein the expansion arm loads a first force in the first hub and maintains the first panel taut and loads a second force in the second hub and maintains the second panel taut. 
     
     
         15 . A blind structure, comprising:
 a first hub, at least one first support arm near a first panel, a second hub, at least one second support arm near a second panel, and an expansion arm detachably securing the first hub structure to the second hub structure and forcing the first hub to contact the first panel and forcing the second hub to contact the second panel.   
     
     
         16 . The blind structure according to  claim 15 , wherein the expansion arm has an adjustable length. 
     
     
         17 . The blind structure according to  claim 15 , further comprising a rear panel connected to the first panel and the second panel. 
     
     
         18 . The blind structure according to  claim 15 , further comprising a rod pocket attached to the first panel and the at least one first arm detachably mounted within the rod pocket. 
     
     
         19 . The blind structure according to  claim 15 , wherein the expansion arm loads a first force in the first hub and maintains the first panel taut and loads a second force in the second hub and maintains the second panel taut. 
     
     
         20 . The blind structure according to  claim 15 , further comprising the blind structure having four of the first support arms each connected to the first hub and four of the second support arms each connected to the second hub.
