Abstract
A railing and method of manufacturing the railing provide for a guard rail having an upper and lower railing and pickets extending between the upper and lower railing joined to posts such that a rib extends from a surface of one or both of the railings bites into an end of the pickets preventing chattering. The method may use a jig to clamp the railings and pickets together during joining to the posts, such as by welding.
Claims14
A method for manufacturing a railing assembly comprising the steps of:
- forming a plurality of holes in a lower channel and an upper channel;
- fitting the lower channel into a lower rail and the upper channel into the upper rail;
- positioning a plurality of pickets in each of the plurality of holes in the lower channel and the upper channel within a jig such that a flat portion of the lower rail and upper rail is exposed and the lower rail, the pickets and the upper rail are compressed into contact;
- joining a plurality of posts to the flat portion of the lower rail and the upper rail such that the railing assembly is fixedly joined.
1 more element
A method for manufacturing a railing assembly, comprising the steps of:
- providing an elongate upper rail and an elongate lower rail;
- integrally forming a first set of front snap fit connectors and back snap fit connectors to said elongate upper and lower rails at predetermined, longitudinally spaced apart intervals, said first set of front and back snap fit connectors depending from said elongate upper rail and projecting upwardly from said elongate lower rail;
- providing an elongate upper channel having an upwardly-opening square U-shape and providing an elongate lower channel having a downwardly-opening square U-shape;
- integrally forming a second set of front snap fit connectors and back snap fit connectors to said elongate upper and lower channels at predetermined, longitudinally spaced apart intervals that substantially correspond to the intervals of said first set of front and back snap fit connectors, said second set of front and back snap fit connectors projecting upwardly from said elongate upper channel and projecting downwardly from said elongate lower channel;
- interlocking said upper rail to said upper channel by snapping together said first set of snap fit connectors formed in said upper rail and said second set of snap fit connectors formed in said upper channel;
- interlocking said lower rail to said lower channel by snapping together said first set of snap fit connectors formed in said lower rail and said second set of snap fit connectors formed in said lower channel;
- forming a plurality of openings in said upper rail and in said lower rail at predetermined longitudinally spaced intervals so that the openings formed in said upper and lower rails are in vertical alignment with one another;
- and
- positioning a plurality of vertically disposed pickets along respective extents of said upper and lower rails with respective upper ends of said pickets disposed in respective openings formed in said upper channel and with respective lower ends of said pickets disposed in respective openings formed in said lower channel.
