Chair arm

Abstract

A chair arm in the invention includes an arm body having a base provided with two recesses in two opposite sidewalls of the base, a mounting seat having a stop plate provided with a raised face at one sidewall of the stop plate and corresponding to one of the recesses, and a cover. The raised face can be fitted into one of the recesses and firmly screwed with the base by screw members. After the cover is closed on the other sidewall of the base, a left or right chair arm of the invention is assembled together and can be fixed at a left or right side of a chair seat by having the other side of the mounting seat fastened at the chair seat. Therefore, only one mold is adapted for the left and right chair arms, thereby reducing the costs in producing two molds and providing easy assemblage.

What is claimed is:  
     
         1 . A chair arm comprising: 
 an arm body having a base located at a lower portion thereof and provided with two polygonal recesses respectively disposed in two opposite sidewalls of said base, a plurality of through holes disposed in an interior of said base and extending through said base in communication with said two opposite recesses, and a plurality of screw members capable of extending through said plurality of through holes;    a mounting seat capable of being combined with one of said two sidewalls of said base of said arm body and having a stop plate disposed at one side thereof and provided with a polygonal raised face disposed at one sidewall of said stop plate and corresponding to one of said two opposite recesses of said base of said arm body; and,    a cover capable of being closed on the other one of said two sidewalls of said base of said arm body.    
     
     
         2 . The chair arm as claimed in  claim 1 , wherein an insert hole is disposed in an interior of said base of said arm body and extending through said base in communication with said two opposite recesses, and said cover has a post disposed therein and provided with an insert rod whose diameter is a little larger than that of said insert hole of said base of said arm body.  
     
     
         3 . The chair arm as claimed in  claim 1 , wherein said polygonal raised face of said mounting seat is provided with a plurality of screw holes.
