Abstract
A metal railing comprises railing sections. Each railing section has an upper hollow handrail, and a lower hollow girder. A center post joins the handrail and the lower girder, and a plurality of filler posts extend between and into the upper handrail and lower girder on each side of the center post. The filler posts are interconnected within the upper handrail and the lower girder by long pins. The railing sections are movably connected to coupling posts or end posts. A cable extends through the upper handrail and is clamped at the coupler posts and at the end posts.
Claims12
A heavy duty metal railing including at least one railing section comprising a hollow upper rail having a lower inner wall, cable means received in said hollow upper rail, at least one hollow lower girder spaced from said upper rail and having an upper inner wall, a center post extending between said upper rail and lower girder, and a plurality of filler bars spaced on each side of said center post, said filler bars having upper ends extending into said upper rail and lower ends extending into said lower girder, a first elongated pin means extending longitudinally in said upper rail and through each end of each filler bar as well as in contact with said lower inner wall of said upper rail of a railing section, a second elongated pin means extending longitudinally in said lower girder and through each lower end of each filler bar as well as in contact with said upper inner wall of said lower girder of a railing section, said first and second pin means interconnecting all the filler bars on the respective side of the center post by a wedging action against the respective inner wall defining a clamping surface to thereby provide a chain formation, in which said filler bars are positively connected to each other through said pin means in a force transmitting manner and whereby said upper rail and said lower girder are also integrated into said chain formation and coupled to each other in a force transmitting manner.
