Handrail Assembly

Abstract

A handrail assembly includes at least one connecting unit, and at least two extension units each connected with the connecting unit. The connecting unit includes a middle tube and two connecting tubes extended from two opposite ends of the middle tube respectively. Each of the connecting tubes has a surface formed with a plurality of elongate slits. Each of the connecting tubes has a periphery formed with an annular reinforcing rib to enhance resilience and fixedness of each of the connecting tubes. Each of the extension units includes a mounting pipe mounted on a respective one of the connecting tubes. Thus, the connecting units and the extension units are detached before assembly to facilitate and reduce the cost of storage, packaging and transportation of the handrail assembly.

1 . A handrail assembly, comprising:
 at least one connecting unit; and   at least two extension units each connected with the connecting unit; wherein:   the connecting unit includes a middle tube and two connecting tubes extended from two opposite ends of the middle tube respectively;   each of the connecting tubes of the connecting unit has a surface formed with a plurality of elongate slits so that each of the connecting tubes of the connecting unit is made resilient by the slits;   each of the extension units includes a mounting pipe mounted on a respective one of the connecting tubes of the connecting unit;   the mounting pipe of each of the extension units has an interior formed with a mounting hole mounted on the respective connecting tube of the connecting unit; and   an outer wall of the mounting pipe of each of the extension units and an outer wall of the middle tube of the connecting unit are flush with each other to form a smooth surface.   
     
     
         2 . The handrail assembly of  claim 1 , further comprising at least one support unit connected with the connecting unit. 
     
     
         3 . The handrail assembly of  claim 2 , wherein the support unit includes a support base connected with the middle tube of the connecting unit, and a fixing plate connected with the support base, the fixing plate of the support unit has a surface formed with a plurality of fastening holes for fastening the fixing plate of the support unit to a wall by a plurality of threaded fastening members, and the support base of the support unit has a first end connected with the middle tube of the connecting unit and a second end connected with the fixing plate. 
     
     
         4 . The handrail assembly of  claim 3 , wherein the support base of the support unit has a substantially cylindrical or arcuate shape. 
     
     
         5 . The handrail assembly of  claim 2 , wherein the connecting unit is made of a metallic material, each of the extension units is made of a metallic material, and the support unit is made of a metallic material. 
     
     
         6 . The handrail assembly of  claim 1 , wherein each of the connecting tubes of the connecting unit has a periphery formed with an annular reinforcing rib to enhance resilience and fixedness of each of the connecting tubes. 
     
     
         7 . The handrail assembly of  claim 1 , wherein the mounting pipe of each of the extension units has an outer diameter equal to that of the middle tube of the connecting unit. 
     
     
         8 . The handrail assembly of  claim 1 , wherein the mounting pipes of the extension units have the same length. 
     
     
         9 . The handrail assembly of  claim 1 , wherein each of the slits is extended in a longitudinal direction of each of the connecting tubes, the reinforcing rib of each of the connecting tubes traverses each of the slits, and the mounting pipe of each of the extension units is juxtaposed to the middle tube of the connecting unit. 
     
     
         10 . The handrail assembly of  claim 1 , wherein the mounting pipe of one of the extension units is an angled bent pipe with different bending angles.
