A corner structure is provided for impact-resisting handrail installations. The design of the structure is such that the same principal components may be employed in constructing outside corners, inside corners and returns. The corner structure includes a molded tubular shell of arcuate configuration, for connection to each of two right angularly related straight handrail sections or from one handrail to an adjacent wall. An internal skeletal support member is mounted within the hollow tubular shell, by means of closure panels secured to and closing the opposite ends of the shell. The skeletal support member includes an arcuate central portion arranged in confronting and supporting relation to the outwardly facing wall of the shell. Connecting elements project outward through each of the closure panels for rigid connection to the adjacent straight handrail sections. By substitution of two different internal skeletal supports, the corner structure can be configured for inside and outside corners. The skeletal supports themselves are adapted to be inexpensively produced by extrusion processes. Substantial savings in manufacturing costs are realized. |
