Vertical cable railing and method of installation

Abstract

A method of assembling and installing a vertical cable infill deck railing system is disclosed in which cables are strung two parallel rails, pulled taut, and tightened into position. The cable railing system resists galvanic corrosion by using a flange nut cap to separate dissimilar metals. The flange nut cap also prevents the associated flange nut from falling if it is overly loosened. Galling is reduced without the need for additional coatings by using a phosphor bronze threaded crimp.

1 . A cable attachment structure comprising a sleeve and a capsule,
 said sleeve has a length, a longitudinal axis, a first end, a second end, an external surface and an internal surface,
 said internal surface having a diameter; 
 said second end adapted to be turned by a tool; 
   said capsule having a length, a longitudinal axis, a first end, a second end, an external surface, and an internal surface defining a lumen;
 said external surface of the capsule having a diameter 
 said capsule capable of being inserted into the sleeve, 
 said external surface of the capsule and the internal surface of the sleeve adapted such that the inserted capsule is capable of movement along the longitudinal axis of the sleeve. 
   
     
     
         2 . The cable attachment structure of  claim 1  in which the external surface of the capsule comprises male threads, and the internal surface of the sleeve comprises corresponding female threads. 
     
     
         3 . The cable attachment structure of  claim 1 , in which the second end of the capsule is adapted to grip a cable inserted through the first end of the capsule. 
     
     
         4 . The cable attachment structure of  claim 2  in which said sleeve is a flange nut. 
     
     
         5 . The cable attachment structure of  claim 2  in which the capsule is a phosphor bronze threaded crimp. 
     
     
         6 . The cable attachment of  claim 2  is in which the male and female threads are compatible such that the capsule is positional within the sleeve. 
     
     
         7 . The cable attachment structure of  claim 1  further comprises a cable crimp at or near the second end of the capsule. 
     
     
         8 . The cable attachment structure of  claim 1  further comprising a cap adapted to be affixed to the first end of the sleeve. 
     
     
         9 . A method of assembling a section of railing having vertical cables comprising the steps of:
 providing a top rail comprising a longitudinal axis, a first end, a second end, a top, a bottom comprising a plurality of holes, and an internal space; and   providing a bottom rail comprising a longitudinal axis, a first end, a second end, a top comprising a plurality of holes, a bottom, and an internal space; and   providing a plurality of cables, each having a top terminus contained within the internal space of the top rail and a bottom terminus contained within the internal space of the bottom rail;
 the top terminus of each cable passes through a hole in the top rail and through a washer and which is secured within the internal space of the top rail with a crimp nut; and 
 the bottom terminus of each cable passing through a hole in the bottom rail, and which is secured within the internal space of the bottom rail with a phosphor bronze threaded crimp contained within a flange nut; 
   providing a spacing rod adapted to provide rigid support separating the bottom of the top rail from the top of the bottom rail;   said cable receiver of the first post having a longitudinal axis largely parallel to the perpendicular axis of the first post; and   removing one or more cables from the top rail and the bottom rail and inserting a spacing rod into the holes exposed in the rails;   gripping a cable adjacent to the spacing rod proximal to the bottom rail to prevent the cable from rotating, rotating the flange nut about the longitudinal axis of the flange nut, causing the phosphor bronze threaded crimp to move within the flange nut and away from the top rail thereby pulling the cable taut; and   similarly pulling each of the other cables taut.   
     
     
         10 . A method of assembling a section of railing having vertical cables and including rail supports comprising the steps of:
 providing a mounting surface;   providing a first rail support post having an inwards-facing side, an outwards-facing side, a longitudinal axis, a top, and a bottom having a base support flange adapted to connect to the mounting surface;   providing a second rail support post having an inwards-facing side, an outwards-facing side, a longitudinal axis, a top, and a bottom having a base support flange adapted to connect to the mounting surface;   providing the section of railing having vertical cables assembled according to claim;   providing suitable hardware for attaching the top rail and the bottom rail of the section of railing to each rail support post;   attaching the first rail support post and the second rail support post to the mounting surface such that the inward-facing sides of each rail support post face each other,   attaching the first end of the top rail to near the top of the inward-facing side of the first rail support,   attaching the second end of the top rail to near the top of the inward-facing side of the second rail support,   attaching the first end of the bottom rail to near the top of the inward-facing side of the first rail support,   attaching the second end of the bottom rail to near the bottom of the inward-facing side of the second rail support.   
     
     
         11 . The method of  claim 9  in which said a flange nut cap is placed over the flange nut which prevents the flange nut and the contained phosphor bronze crimp from contacting the bottom rail. 
     
     
         12 . The method of  claim 9  in which the flange nut further comprises and longitudinal axis. and is adapted to be held by a tool and rotated along said longitudinal axis.
