Armrest Structure for Railing

Abstract

An armrest structure for a railing contains: at least one upright post, a handrail mounted on the at least one upright post, and multiple first connectors. Each first connector is defined between each of the at least one upright post and the handrail, said each first connector includes a first connection part and a second connection part, a first end of the first connection part couples with said each upright post, and the first connection part has a first connecting portion extending outwardly from a second end of the first connection part, the second connection part is locked on a bottom of the handrail and has two second connecting portions configured to rotatably connect with the first connecting portion of the first connection part.

What is claimed is: 
     
         1 . An armrest structure for a railing comprising:
 at least one upright post;   a handrail mounted on the at least one upright post;   multiple first connectors, wherein each first connector is defined between each of the at least one upright post and the handrail, said each first connector includes a first connection part and a second connection part, a first end of the first connection part couples with said each upright post, and the first connection part has a first connecting portion extending outwardly from a second end of the first connection part, the second connection part is locked on the handrail and has two second connecting portions configured to rotatably connect with the first connecting portion of the first connection part.   
     
     
         2 . The armrest structure for the railing as claimed in  claim 1 , wherein the first connection part of said each first connector is a L-shaped tube or a T-shaped tube. 
     
     
         3 . The armrest structure for the railing as claimed in  claim 1 , wherein the first connection part of said each first connector has an extension extending on the first end thereof, and the extension is a threaded section so as to screw with an upper end of said each upright post or is a bolt section so as to connect with the upper end of said each upright post. 
     
     
         4 . The armrest structure for the railing as claimed in  claim 1 , wherein the second connection part of said each first connector is locked on a bottom of the handrail by way of two first screw bolts. 
     
     
         5 . The armrest structure for the railing as claimed in  claim 1 , wherein the second connection part of said each first connector is an integrally formed sheet. 
     
     
         6 . The armrest structure for the railing as claimed in  claim 1 , wherein the second connection part of said each first connector has an accommodation portion defined on a central position thereof so that the first connection part inserts the accommodation portion, and the accommodation portion has the two second connecting portions which are concavely arcuate and are integrally arranged on two peripheral sides of the accommodation portion respectively. 
     
     
         7 . The armrest structure for the railing as claimed in  claim 6 , wherein the second connection part of said each first connector also has a limiting piece extending outwardly from one of the two peripheral sides of the accommodation portion thereof, and the second connection part further has two stop pieces integrally extending outward adjacent to the two second connecting portions respectively so as to limit the first connecting portion of the first connection part. 
     
     
         8 . The armrest structure for the railing as claimed in  claim 1 , wherein The second connection part has a limiting piece fixed on a top thereof and has two stop pieces integrally extending outward adjacent to the two second connecting portions respectively so as to limit the first connecting portion of the first connection part. 
     
     
         9 . The armrest structure for the railing as claimed in  claim 1 , wherein multiple second connectors are mounted on step faces of the stairs individually, and an extension of a first connection part of each second connector is connected with a lower end of said each upright post, a second connection part of said each second connector is locked on said each step face of the stairs by using two second screw bolts. 
     
     
         10 . The armrest structure for the railing as claimed in  claim 1 , wherein each of multiple second connectors is coupled with a horizontal rod, and an extension of a first connection part of said each second connector is locked on a lower end of said each upright post, and a second connection part of said each second connector is locked on a top of the horizontal rod by using two second screw bolts.
