Deflection resistant tent

Abstract

A deflection resistant tent is set forth. The framework of this tent comprises an upper nest, an lower nest, a plurality of upper rib strips, lower rib strips, auxiliary rib strips, adjustable collars, articulation members, and spring stays. The articulation member is composed of an upper sleeve, a retainer, a torque member, and a lower sleeve. With this structure, the elastic force of the spring stay controls the retainer to make clockwise rotation until it is stopped by a blocking face so as to settle the lower sleeve at a desire position that can prevent the unexpected collapsing of the tent by a sudden external force or a violent wind blow.

1 . A deflection resistant tent whose framework being comprising an upper nest, a lower nest, a plurality of upper rib strips, lower rib strips, auxiliary rib strips adjustable collars, articulation members, and springs stays, the plural amount of above mentioned component parts except the upper and lower nest being equal; wherein 
 each adjustable collar is fitted to said corresponding upper rib strip at a proper position thereof, said adjustable collar has a holder on it;    each articulation member is composed of an upper sleeve and a lower sleeve, said upper sleeve accepts insertion of said corresponding upper rib strip, a mouth with a via hole at its inner side is formed at the lower end of said upper sleeve, a retainer is shackled in said mouth and exposed out of said via hole, a torque member is provided for controlling clockwise rotating force of said retainer, said lower sleeve is for insertion of the top end of said lower rib strip and has a hinge joint at its upper portion to hinge into said mouth, the upper edge of said hinge joint is formed into a blocking face occupying just on rotating way of said retainer so as to limit movement of said lower sleeve, each spring stay is fastened between said holder of said adjustable collar and said retainer of said articulation member; with the elastic force of said spring stay to control clockwise rotation of said retainer until it is stopped by a blocking face formed on said hinge joint thereby said lower sleeve is settled at the position    
   
   
       2 . The deflection resistant tent of  claim 1 , wherein said lower nest is provided under said upper nest, one end of each said upper rib strip is inserted and hinged to the edge of said upper nest, while the other end thereof is stretched downwards, each said auxiliary rib strip is hinged to the edge of said lower nest with its one end, and the other end thereof is attached to the corresponding adjustable collar, each said lower rib strip is inserted into said lower sleeve of said articulation member.  
   
   
       3 . The deflection resistant tent of  claim 1 , wherein a drilled hole is formed at the inner side of said retainer for fastening said spring stay.  
   
   
       4 . The deflection resistant tent of  claim 1 , wherein said retainer and the hinge joint of said lower sleeve is respectively hinged in said mouth with a set pin.  
   
   
       5 . The deflection resistant tent of  claim 4 , wherein said retainer is provided with a hinge hole for a set pin to insert into.  
   
   
       6 . The defection resistant tent of  claim 4 , wherein said torque member is provided with a passing hole at its center at the position corresponding to the hinge hole of said retainer for a set pin to insert into.  
   
   
       7 . The deflection resistant tent of  claim 1 , wherein said holder is provided at the inner side of said adjustable collar.
