Abstract

A stair railing system is provided. The system is comprised of a handrail system comprising at least two handrails positioned at varying or identical heights relative to the stairs of a staircase to enhance accessibility and safety for users of differing physical needs. Each handrail includes a body with customizable cross-sectional shapes, constructed from materials such as metals, composites, polymers, or natural materials, and features grip-enhancing surface textures. Mounting brackets secure the handrails to walls, accommodating diverse installation angles. The handrails may be tiered at non-continuous heights, providing superior support by enabling users to easily stabilize themselves during falls. Optionally, handrails may overlap or leave gaps and can incorporate flat surfaces for aesthetic or functional use. The system further includes a method for installation and use, ensuring stability and usability when navigating staircases.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A stair railing system comprising:
 a first handrail comprised of a first mounting bracket and a first body comprised of a first first end and a first second end, wherein the first handrail is positioned over a first stair, a second stair, and a third stair of a staircase; and   a second handrail comprised of a second mounting bracket and a second body comprised of a second first end and a second second end;   wherein the second handrail is positioned over the third stair, a fourth stair, and a fifth stair of a staircase; and   wherein the first handrail is positioned above the second handrail in a parallel arrangement on a wall surface and in a non-overlapping position.   
     
     
         2 . The stair railing system of  claim 1 , wherein the first handrail is comprised of a grip area. 
     
     
         3 . The stair railing system of  claim 2 , wherein the grip area is comprised of a knurling. 
     
     
         4 . The stair railing system of  claim 2 , wherein the grip area is comprised of a groove. 
     
     
         5 . The stair railing system of  claim 2 , wherein the grip area is comprised of a raised pattern. 
     
     
         6 . The stair railing system of  claim 2 , wherein the grip area is comprised of a non-slip coating. 
     
     
         7 . The stair railing system of  claim 1 , wherein the first mounting bracket and the second mounting bracket are comprised of a flat plate, a U-shaped clamp, or an adjustable joint. 
     
     
         8 . The stair railing system of  claim 1 , wherein the first handrail is comprised of a flat surface. 
     
     
         9 . The stair railing system of  claim 1 , wherein the second handrail is comprised of a flat surface. 
     
     
         10 . A stair railing system comprising:
 a first handrail comprised of a first mounting bracket and a first body comprised of a first first end and a first second end, wherein the first handrail is positioned over a first stair, a second stair, and a third stair of a staircase; and   a second handrail comprised of a second mounting bracket and a second body comprised of a second first end and a second second end;   wherein the second handrail is positioned over the third stair, a fourth stair, and a fifth stair of a staircase; and   wherein the first handrail is positioned above the second handrail on a wall surface in a parallel arrangement and in an overlapping position wherein the first second end and the second first end overlap.   
     
     
         11 . The stair railing system of  claim 10 , wherein the first handrail is comprised of a grip area. 
     
     
         12 . The stair railing system of  claim 11 , wherein the grip area is comprised of a knurling. 
     
     
         13 . The stair railing system of  claim 11 , wherein the grip area is comprised of a groove. 
     
     
         14 . The stair railing system of  claim 11 , wherein the grip area is comprised of a raised pattern. 
     
     
         15 . The stair railing system of  claim 11 , wherein the grip area is comprised of a non-slip coating. 
     
     
         16 . The stair railing system of  claim 10 , wherein the first mounting bracket and the second mounting bracket are comprised of a flat plate, a U-shaped clamp, or an adjustable joint. 
     
     
         17 . The stair railing system of  claim 10 , wherein the first handrail is comprised of a flat surface. 
     
     
         18 . The stair railing system of  claim 10 , wherein the second handrail is comprised of a flat surface. 
     
     
         19 . A method of using a stair railing system, the method comprising the following steps:
 providing a stair railing system comprised of a first handrail and a second handrail;   attaching the first handrail to a wall surface at a first height above a first stair of a staircase;   attaching the second handrail to a wall surface at a second height above a second stair of a staircase;   walking up or down the staircase while grasping the first handrail or the second handrail to prevent falling.   
     
     
         20 . The method of using a stair railing system of  claim 19 , wherein the first handrail overlaps the second handrail in a non-aligned position.
