Structure with rolling roof top cover

Abstract

A structure with a rolling roof cover, for example, a gazebo with a retractable cover, where the retractable cover is connected by a pull cord to a winding device, wherein operation of the winding device allows the user to open or retract the cover. The cover can be opened and closed very easily and provides flexibility to the user.

1 . A structure having a retractable cover, comprising: 
 a first corner pole having a first top end and a first bottom end;    a second corner pole having a second top end and a second bottom end;    a crossbeam having a first end and a second end;    a first beam having a first front end and a first rear end;    a second beam having a second front end and a second rear end;    a reel;    a cover having a leading edge;    a pull cord;    a winding device;    a first pulley; and    a second pulley,    wherein 
 said first top end, said first end, and said first front end are contiguous to one another and joined to form a first front junction,  
 said second top end, said second end, and said second front end are contiguous to one another and joined to form a second front junction,  
 said first corner pole and said second corner pole are located in a first plane,  
 said first beam and said second beam are parallel to each other and located in a second plane different from said first plane,  
 said first corner pole and said first beam are located in a third plane different from said first plane and said second plane,  
 said second corner pole and said second beam are located in a fourth plane different from said first plane, said second plane, and said third plane,  
 said cover is wound about said reel, and said reel and said crossbeam are parallel to each other,  
 said first pulley and said second pulley are joined to said structure,  
 said pull cord connects said leading edge of said cover with said winding device through said first pulley and said second pulley, and  
   wherein operation of said winding device in one direction results in expansion of said cover in a direction towards said crossbeam, and wherein operation of said winding device in an opposite direction results in retraction of said cover in a direction towards said reel.    
   
   
       2 . The structure of  claim 1 , wherein said reel is spring-loaded.  
   
   
       3 . The structure of  claim 1 , wherein said first plane, said second plane, and said third plane are normal to one another, and said first plane, said second plane, and said fourth plane are normal to one another.  
   
   
       4 . The structure of  claim 1 , further comprising a second crossbeam having a first end and a second end, wherein said second crossbeam and said crossbeam are parallel to each other, said first end of said second crossbeam and said first rear end of said first beam are contiguous to each other and joined to form a first rear junction, and said second end of said second crossbeam and said second rear end of said second beam are contiguous to each other and joined to form a second rear junction.  
   
   
       5 . The structure of  claim 4 , wherein said second crossbeam is contiguous to said reel.  
   
   
       6 . The structure of  claim 4 , wherein said second crossbeam is joined to said reel.  
   
   
       7 . The structure of  claim 1 , further comprising a shaft having a first end and a second end, wherein said shaft is joined to said leading edge of said cover, said shaft and said crossbeam are parallel to each other, and said pull cord is joined to said shaft.  
   
   
       8 . The structure of  claim 7 , wherein said first end of said shaft comprises a first roller, said second end of said shaft comprises a second roller, said first beam comprises a first slide rail, said second beam comprises a second slide rail, said first slide rail and said second slide rail are parallel to each other, said first roller is slideably mounted in said first slide rail, and said second roller is slideably mounted in said second slide rail.  
   
   
       9 . The structure of  claim 1 , wherein said first pulley is joined to said first corner pole or said crossbeam and is contiguous to said first front junction.  
   
   
       10 . The structure of  claim 1 , wherein said second pulley is joined to said crossbeam.  
   
   
       11 . The structure of  claim 1 , wherein said first corner pole and said second corner pole are parallel to each other.  
   
   
       12 . The structure of  claim 4 , further comprising a third corner pole having a third top end and a third bottom end and a fourth corner pole having a fourth top end and a fourth bottom end, wherein said third corner pole and said fourth corner pole are located in a fifth plane, said third top end is contiguous to and joined with said first rear junction, and said fourth top end is contiguous to and joined with said second rear junction.  
   
   
       13 . The structure of  claim 12 , wherein said fifth plane, said second plane, and said third plane are normal to one another, and said fifth plane, said second plane, and said fourth plane are normal to one another.  
   
   
       14 . The structure of  claim 12 , wherein said third corner pole and said fourth corner pole are parallel to each other.
