Detachable three-piece chair

Abstract

A detachable chair includes a first frame member including two first side rails having a lengthwise slit, front first cross rails, and rear second cross rails; a second frame member including two second side rails, first seat rails having either end portion projecting laterally out of the second side rail, and a second seat rail disposed rearward of the first seat rails and having either end being about flush with an outer surface of the second side rail; and a backrest including two side sheaths adapted to insert through the slits and fastened by rods. Inserting the second frame member through a gap between one second cross rail and one first cross rail until being stopped by the first frame member with the second side rails rested upon one first cross rail will assemble the inclined frame members as a chair.

1 . A detachable chair comprising:
 a first frame member including two parallel first side rails having a leg and a lengthwise slit, a plurality of front first cross rails interconnecting the first side rails, and a plurality of rear second cross rails interconnecting the first side rails;   a second frame member including two parallel second side rails having a leg, a plurality of first seat rails interconnecting the second side rails and having either end portion projecting laterally out of the second side rail, and a second seat rail disposed rearward of the first seat rails and interconnecting the second side rails, the second seat rail having either end being about flush with an outer surface of the second side rail wherein a transverse length of the second frame member is smaller than a distance between inner side surfaces of the first side rails by a predetermined minimum value; and   a backrest including a sheath at either side, the sheaths being adapted to insert through the slits to dispose internally of the first side rails, and two stop members disposed through the sheaths and urged against the slits;   whereby inserting the second frame member through a gap between one of the second cross rails and one of the first cross rails until being stopped by the first frame member with the second side rails rested upon one of the first cross rails will assemble the inclined first and second frame members as a chair.   
   
   
       2 . The chair of  claim 1 , wherein each of the legs of the first side rails has an inclined bottom.
