Abstract

Disclosed is a joining technique to make handrails with stanchions that are the vertical supports that attach to the platform and/or stair stringer at their bottom and attach to the top rail at their top. The stanchions are usually welded or bolted on both ends

Description

  • This application claims priority to U.S. Provisional Application 60/950,593 filed Jul. 18, 2007, the entire disclosure of which is incorporated by reference.
    • TECHNICAL FIELD & BACKGROUND
  • The present invention generally relates to a joining technique. More specifically, the present invention relates a joining technique to make handrails.
  • The present invention may be used on stairs and handrails. Components on the present invention may be made of mirrored finished or brushed stainless steel, aluminum, brass, chrome, fiberglass or any other appropriate material. A main handrail or top rail is the portion that one actually grabs or holds as one walks up a stair or across a platform. The top rail usually has a pipe or round tube that may be one and one half to two inches in outside diameter. Shapes including oval, rectangle, and various other profiles may be used for top rails. The present invention works with all shapes but to save money square or rectangle tubing can be used. Industrial square tubing commonly comes in 20 foot lengths.
  • The present invention has stanchions that are the vertical supports that attach to the platform and/or stair stringer at their bottom and attach to the top rail at their top. The stanchions are usually welded or bolted on both ends. The present invention joining system employs an alpha connection or connection A to accomplish the joint at the top and bottom of the stanchion. An internal attachment fitting is properly positioned and securely welded on the inside to the underside of the top rail. An internal attachment fitting is properly positioned and securely welded on the inside to the topside of the platform stringer. The stanchion is lowered and placed in such a way that the welded in place internal attachment fitting on the topside of the platform stringer is inserted up into the stanchion. The stanchion is checked to insure plumb alignment and plug welded, bolted or attached by any other means to secure the stanchion bottom to the platform stringer.
  • The structural integrity of the unit is primarily dependent on the welding of the internal attachment fitting. The resulting joint is a clean precision joint with no welding globs showing. The present invention joining system employs a bravo connection or connection B to accomplish the joint at the mid rail attachment at both sides of the stanchion. The same or similar procedure may be used at each attachment point for all the different joint designs.
  • The present invention joining system employs a Charlie connection or connection C to accomplish the joints at the top and bottom of the stanchion. The same or similar procedure may be used at each attachment point for all the different joint designs. The present invention joining system employs a delta connection or connection D to accomplish the joints at changes in direction for the top rail design. The same or similar procedure may be used at each attachment point for all the different joint designs. An internal alignment connector can be properly positioned and securely held while both pieces to be joined are plug welded, bolted or attached by any other means to secure the top rail for changes in direction which is typically forty five degrees.
