Grab bar assembly

Abstract

A grab bar assembly includes a grab bar, a mounting flange and an annular cover. A connective block with a bolt hole thereof is fixed on inner side of an end surface of the grab bar. An axial columnar projection with a central insertion hole is arranged on the mounting flange. The central insertion hole forms a countersunk end on the bottom of the mounting flange. When being assembled, the end surface of the grab bar connects with the columnar projection of the mounting flange. An inner hexagonal countersunk screw inserts through the central insertion hole from the countersunk end on the bottom of the mounting flange and threads into the bolt hole of the connective block on the end surface of the grab bar so as to fasten the grab bar with the mounting flange. Then the annular cover is assembled with the mounting flange by the inner thread threaded with the outer thread so as to make the annular cover fix on the mounting flange firmly and shield the mounting flange.

1 . A grab bar assembly comprising a grab bar, a mounting flange and an annular cover while the grab bar having two end surfaces, each end surface having a corresponding mounting flange and a corresponding annular cover, wherein 
 the grab bar having two end surfaces; a connective block with a bolt hole is fixed on tubular inner side of each end surface;    the mounting flange having a plurality of fixing hole for being fixed on a wall by a fastener; an axial columnar projection with an axial insertion hole that forms a countersunk end; and an outer thread on outer surface thereof;    the annular cover having a central hole whose diameter is a bit larger than diameter of the grab bar so as to make the annular cover insert through the grab bar and shift; an inner thread is installed on inner side of the bottom of the annular cover for being threaded with the outer thread so as to fasten the annular cover with the mounting flange; in accordance with above structure, the end surface of the grab bar connects with the columnar projection of the mounting flange; by an inner hexagonal countersunk screw inserting through the axial insertion hole from the bottom of the mounting flange and being threaded into the bolt hole of the connective block on the end surface of the grab, the grab bar is fastened with the mounting flange; the mounting flange of the end surface is fixed on the wall by the fastener; the annular cover is threaded with the mounting flange by the inner thread matching with the outer thread so as to make the annular cover fix on the mounting flange firmly and shield the mounting flange.    
   
   
       2 . The device as claimed in  claim 1 , wherein the depth of the inner thread of the annular cover is larger than the height of the of the outer thread of the mounting flange.  
   
   
       3 . The device as claimed in  claim 1 , wherein the annular cover having certain height for covering and shielding the mounting flange.  
   
   
       4 . The device as claimed in  claim 1 , wherein the annular cover having various shapes.  
   
   
       5 . The device as claimed in  claim 3 , wherein the annular cover having various shapes.
