Collapsible furniture structure and assembly method

Abstract

An article of collapsible furniture having parallel side frames ( 1 and 2 ) each side frame having oppositely threaded sockets ( 12 a,b,c and 13 a,b,c ) into which crossbars ( 3, 4, 5, 8 a,b,c and 9 a,b,c ) having opposite threaded ends can be rotatably inserted simultaneously into the sockets ( 12 a,b,c and 13 a,b,c ) on the side frames ( 1 and 2 ) to form the article of collapsible furniture. A fabric cover ( 14, 15, and 16 ) can be utilized to provide a seat for the collapsible furniture. Methods of assembly are provided.

Having thus described my invention, I claim:  
     
         1 . An article of collapsible furniture comprising; 
 at least two parallel side frames, each frame having at least two legs and a plurality of positionably matching sockets, the sockets on one frame being oppositely threaded from the sockets on the other frame; and    a plurality of crossbars each having ends that are threaded in the opposite direction for threadable insertion into the sockets, such that when the crossbars are rotated in one direction the crossbars are threadably inserted into the sockets of the parallel frames to secure the frames to form the article of furniture.    
     
     
         2 . The article of collapsible furniture of  claim 1 , further comprising a fabric cover having a plurality of channels sewn therein into which crossbars can be inserted to form a fabric seat for the article of furniture.  
     
     
         3 . The article of collapsible furniture of  claim 1  wherein each of said parallel frames and each of the said sockets is marked for matching purposes.  
     
     
         4 . The article of collapsible furniture of  claim 2  wherein each of said parallel frames and each of the said sockets is marked for matching purposes.  
     
     
         5 . A method of assembling an article of collapsible furniture comprising 
 parallel side frames each having at least two legs and a plurality of positionably matching sockets, the sockets on one frame being oppositely threaded from the sockets on the other frame; and a plurality of crossbars each having ends that are threaded in the opposite direction for threadable insertion into the sockets, such that when the crossbars are rotated in one direction the crossbars are threadably inserted into the sockets of the parallel frames to secure the frames to form the article of furniture, said method comprising the steps of: 
 positioning one of the side frames on a planar surface with the sockets facing upward;  
 inserting partially a threadably matching end of a crossbar into each of the sockets in said one of the side frames so that the crossbars are perpendicular to the frame;  
 aligning another side frame over the crossbars so that the end of each crossbar is aligned with a socket on said another side frame; and  
 rotating each crossbar in one direction so that each crossbar simultaneously becomes threadably inserted into the sockets on the side frames until each crossbar is secured in said sockets to form the article of furniture.  
   
     
     
         6 . A method of assembling an article of collapsible furniture comprising 
 parallel side frames each having at least two legs and a plurality of positionably matching sockets, the sockets on one frame being oppositely threaded from the sockets on the other frame; and a plurality of crossbars each having ends that are threaded in the opposite direction for threadable insertion into the sockets, such that when the crossbars are rotated in one direction the crossbars are threadably inserted into the sockets of the parallel frames to secure the frames to form the article of furniture, said method comprising the steps of: 
 positioning one of the side frames on a planar surface with the sockets facing upward; a fabric cover having a plurality of channels sewn therein into which crossbars can be inserted to form a fabric seat, said method comprising the steps of: 
 inserting each crossbar into a channel of the fabric cover;  
 inserting partially a threadably matching end of a crossbar into each of the sockets in said one of the side frames so that the crossbars are perpendicular to the frame;  
 aligning another side frame over the crossbars so that the end of each crossbar is aligned with a socket on said another side frame; and  
 rotating each crossbar in one direction so that each crossbar simultaneously becomes threadably inserted into the sockets on the side frames until each crossbar is secured in said sockets to form the article of furniture.
