  • Patent number: 4646490
    Abstract: A top rail for handrails comprises a top rail body formed of soft synthetic resin, semi-hard synthetic resin or synthetic rubber and having a bendable metal core incorporated therein extending in the longitudinal direction thereof. The bendable metal core is bendable under a force in excess of a predetermined value and maintains the top rail body in its bent position when the core is bent together with the body. The bendable metal core can be the form of an elongated solid steel bar, to which a lubricant has been applied to the surface thereof and soft or semi-hard synthetic resin is extruded about the lubricant applied surface to form the top rail body. The bendable metal core can also be in the form of an elongated solid aluminum or aluminum alloy bar to which is applied adhesive about the surface thereof and soft or semi-hard synthetic resin is extruded about the adhesive applied surface.
