Abstract
A handrail article containing integral nodes continuously spaced along the axis of the rail at approximate hand spacing to reduce muscle torque strain and fatigue (Isokinetics) resulting from strength applied to overcome sliding of hand grip while sustaining balance during travel on stairways. To incorporate a non-metallic nodal rail component into a railing assembly, metal is embedded into the rail article for welding to posts of the balustrade assembly.
Claims

2 . Non-metallic nodal hand rails as per claim 1 , strengthened with a metallic insert and affixed by welding to metal baluster assemblies.Join the waitlist — get patent alerts
