Foldable director's chair

Abstract

A foldable director's chair comprises a pair of armrest unit and leg frame unit. Each armrest unit and leg frame unit is hollow tube of which the right angle ends extending straightly downward or upward for a suitable length with their opening of the tubes corresponding to each other via a gliding tube connecting through the armrest unit and the leg frame unit. The diameter of the gliding tube is smaller than that of the tube of the armrest unit allowing one end of each gliding tube being able to engaged through the tube of the armrest unit and fixed to each other via nails and first retaining sleeve while another end being engaged through the leg frame unit without being fixed thereto allowing the armrest unit moving straightly upward or downward along the gliding tube.

1 . A foldable director's chair comprising:
 an armrest unit and a leg frame unit both being hollow tube with their right angle ends extending straight downward or upward for a suitable length with their opening of the tubes corresponding to each other;   a gliding tube of which the diameter is slightly smaller than that of said armrest unit and leg frame unit, connecting through said armrest unit and said leg frame unit; one end of each said gliding tube being installed through said armrest unit and fixed thereto via first retaining sleeve and nails, while another end being installed through said leg frame unit without being fixed allowing said armrest unit moving straightly upward or downward along said gliding tube.   
   
   
       2 . A foldable director's chair as recited in  claim 1 , wherein said first retaining sleeve is installed through inside the bottom of said armrest unit and fixed to said gliding tube via said nails; each second retaining sleeve is installed through said leg frame unit at a suitable height thereof and fixed thereto via nails without being fixed to another end of said gliding tube. 
   
   
       3 . A foldable director's chair as recited in  claim 1 , wherein a protrusion extending from inside edge of each said first and second retaining sleeve respectively to pivotally engage with each end of a arc-shaped supporting unit; said gliding tube is able to move upward with a suitable height without being departed from said leg frame unit during folding transversely; said gliding tube is overlapped and covered by said leg frame unit by bottom of said armrest unit leaning against the top of said leg frame unit so as to form an arresting assembly during unfolding and being seated 
   
   
       4 . A foldable director's chair as recited in  claim 1 , wherein a seat supporting unit is installed at the top of said first retaining sleeve between said armrest units respectively; a canvas seat is able to engage through said seat supporting unit of which the front edge is exceeding the edge of said armrest unit. 
   
   
       5 . A foldable director's chair as recited in  claim 1 , wherein the lower portion of said gliding tube is installed through inside of said leg frame unit having said second retaining sleeve engaged through and fixed via said nails; the upper portion of said gliding tube is installed through inside of said armrest unit without being fixed so as to allow said gliding tube able to move along and the bottom of said armrest unit able to move downward leaning against the top of said leg frame unit.
