Tent having improved windproof and ventilation abilities

Abstract

A tent has at least one main pole fixed to a ground with being bended into an arch shape so as to constitute a frame of the tent, a main body made of waterproof fabric and expanded by the main pole to form a dome shape having a predetermined volume, and a wind screen provided to the highest top portion of the main body so as to extend while approximately forming a horizontality with the ground and capable of resisting wind flowing along an outer surface of the main body. According to the tent, since the side of the tent is raised due to the wind screen even when the strong wind blows, it is possible to the original shape of the tent without any deformation.

1 . A tent comprising: 
 at least one main pole fixed to a ground with being bended into an arch shape so as to constitute a frame of the tent;    a main body made of waterproof fabric and expanded by the main pole to form a dome shape having a predetermined volume; and    a wind screen provided to the highest top portion of the main body so as to extend while approximately forming a horizontality with the ground and capable of resisting wind flowing along an outer surface of the main body.    
   
   
       2 . The tent according to  claim 1 , wherein the wind screen is extended into front and rear of the main pole to form a tunnel shape.  
   
   
       3 . The tent according to  claim 2 , wherein the wind screen comprises: 
 at least one sub-pole provided to the highest top portion of the main pole so as to intersect the main pole while approximately forming a horizontality with the ground, and    screen fabric having both ends to be fixed to the outer surface of the main body and protruding from the outer surface of the main body into the tunnel shape when a central portion of the screen fabric is stretched by the sub-pole.    
   
   
       4 . The tent according to  claim 1 , further comprising: 
 an upper ventilation window formed at a lower side of the wind screen of an upper portion of the main body; and    a lower ventilation window formed at a lower portion of the main body,    wherein air in the tent flows vertically from the lower ventilation window toward the upper ventilation window, thereby ventilating the inside of the tent.    
   
   
       5 . The tent according to  claim 2 , further comprising an entrance having a size over a total area at the front side and a ventilation window formed to be screened by the window screen at an upper portion of the rear side of the main body.  
   
   
       6 . A tent comprising: 
 at least one main pole fixed to a ground with being bended into an arch shape so as to constitute a frame of the tent;    a main body comprised of waterproof fabric and expanded by the main pole to form a dome shape having a predetermined volume;    a fly covering the main body; and    a wind screen provided to the highest top portion of the fly so as to extend while approximately forming a horizontality with the ground and capable of resisting wind flowing along an outer surface of the fly.    
   
   
       7 . The tent according to  claim 6 , wherein the wind screen comprises: 
 at least one sub-pole provided to the highest top portion of the main pole with being bended to have a radius of curvature larger than that of the fly at the highest top portion of the fly; and    screen fabric having both ends to be fixed to an outer surface of the main body and protruding from the outer surface of the fly into a tunnel shape when a central portion of the screen fabric is upwardly stretched by the sub-pole.    
   
   
       8 . The tent according to  claim 6 , further comprising a ventilation window formed to be screened by the wind screen at an upper portion of the fly.  
   
   
       9 . The tent according to  claim 6 , further comprising a pair of fly poles provided to front and rear of the main body with being bended, respectively, and supporting the fly to extend into the front and rear of the main body, 
 wherein the wind screen is formed at the highest top portion of each of the fly poles.
