Structure of a mesh supporting frame of a mesh chair and assembly of the mesh chair

Abstract

A mesh chair includes a mesh supporting frame, and a mesh positioned over and joined on the mesh supporting frame; the mesh supporting frame has several joining post portions spaced apart on a loop-shaped side thereof; the mesh is stretched to a tense state and joined on the mesh supporting frame with the joining post portions of the frame being passed through the openings on the periphery thereof; afterwards, a wrapping layer is formed over and around the joint between the mesh and the mesh supporting frame by injection molding to join the mesh and the mesh supporting frame together; thus, the mesh is firmly joined on the mesh supporting frame, having such a tension and elasticity as to provide supporting force to a sitter on the mesh chair.

       5 . The mesh supporting frame structure of a mesh chair as claimed in  claim 1 , wherein the mesh supporting frame has a joining cavity, and the joining post portions exist in the joining cavity. 
   
   
       6 . The mesh supporting frame structure of a mesh chair as claimed in  claim 5 , wherein the joining post portions have an insertion piece joined on a bottom part thereof, and the insertion piece is inserted in the joining cavity of the mesh supporting frame. 
   
   
       7 . The mesh supporting frame structure of a mesh chair as claimed in  claim 1 , wherein the joining post portions each become gradually narrower towards one end thereof. 
   
   
       8 . The mesh supporting frame structure of a mesh chair as claimed in  claim 1 , wherein the mesh supporting frame has a plurality of containing cavities next to the joining post portions. 
   
   
       9 . The mesh supporting frame structure of a mesh chair as claimed in  claim 1 , wherein the mesh supporting frame has a hollow portion on a middle thereof, and a plurality of supporting ribs are joined on the mesh supporting frame; the supporting ribs bending rearwardly of the mesh supporting frame so that the mesh supporting frame has a front recessed portion in front of the supporting ribs. 
   
   
       10 . An assembly structure of a mesh chair, comprising a mesh supporting frame;
 a mesh positioned over and joined on the mesh supporting frame; and   a wrapping layer firmly joining the mesh and the mesh supporting frame together; the wrapping layer being formed with injection molding after the mesh is joined on the mesh supporting frame;   the mesh supporting frame having a plurality of joining post portions thereon;   the mesh being stretched to a tense state and joined on the mesh supporting frame with the joining post portions being passed through openings of a periphery of the mesh.   
   
   
       11 . The assembly structure of a mesh chair as claimed in  claim 10 , wherein the mesh supporting frame has a hollow portion on a middle thereof, and a plurality of supporting ribs are joined on the mesh supporting frame; the supporting ribs bending rearwardly of the mesh supporting frame so that the mesh supporting frame has a front recessed portion in front of the supporting ribs. 
   
   
       12 . The assembly structure of a mesh chair as claimed in  claim 10 , wherein the joining post portions each become gradually narrower towards one end thereof. 
   
   
       13 . The assembly structure of a mesh chair as claimed in  claim 10 , wherein the mesh supporting frame has a plurality of containing cavities next to the joining post portions thereof, and a periphery of the mesh is received in the containing cavities. 
   
   
       14 . The assembly structure of a mesh chair as claimed in  claim 13 , wherein a plurality of pressing strips are inserted in the containing cavities of the mesh supporting frame to press the periphery of the mesh received in the containing cavities. 
   
   
       15 . The assembly structure of a mesh chair as claimed in  claim 14 , wherein the pressing strips have a plurality of through holes thereon. 
   
   
       16 . The assembly structure of a mesh chair as claimed in  claim 10 , wherein the joining post portions exist on a rear side of the mesh supporting frame. 
   
   
       17 . The assembly structure of a mesh chair as claimed in  claim 10 , wherein the joining post portions exist on a front side of the mesh supporting frame. 
   
   
       18 . The assembly structure of a mesh chair as claimed in  claim 10 , wherein the joining post portions exist on a circumferential portion of the mesh supporting frame. 
   
   
       19 . The assembly structure of a mesh chair as claimed in  claim 10 , wherein the mesh supporting frame has a joining cavity, and the joining post portions exist in the joining cavity. 
   
   
       20 . The assembly structure of a mesh chair as claimed in  claim 19 , wherein the joining post portions have an insertion piece joined on a bottom part thereof, and the insertion piece is inserted in the joining cavity of the mesh supporting frame.
