Abstract:
1. An internal structural mullion for a standing seam panel system, comprising: a main extrusion having an open side, an opposing closed side, an innermost portion, and a main hooked portion opposite said innermost portion, said main extrusion further comprising a cavity defined along said open side proximate to said innermost portion, and a screw track defined within said open side adapted to receive a screw; an internal leg formed parallel to said screw track spanning a distance between said open side and said closed side and having two internal leg ends, one of said internal leg ends formed integral to said closed side and the other of said internal leg ends terminating at said open side; a secondary extrusion having a first leg portion, a medial leg portion, an end leg portion, and a leg hooked portion; a screw hole defined through said medial leg portion positioned to be in alignment with said screw track of said main extrusion; and, said secondary extrusion further comprising a foot formed integral to said first leg portion and configured to seat within said cavity of said main extrusion, wherein upon insertion of said foot into said cavity, said leg hooked portion opposes said main hooked portion and said foot forms a fulcrum about which said secondary extrusion can bend away from said main extrusion and be tightened or loosening by the tightening or loosing of said screw, as a result forming a two-piece clamp for engaging panels of said panel system with variable pressure.
