Abstract
A novel overhead door section system and method, the section including a section facing fabricated from a high tensile steel and secured to a novel end stile and center stile. The end stile includes an angle support secured therein. The angle support clamps an end of the section facing against a front face of the end stile and is secured to ribs in the section facing and to a side wall of the end stile. A novel back facing and method provide additional strength to the panel and may also enclose an insulative layer inside the panel.
Claims19
An overhead door section comprising:
- a substantially rectangular sheet of metal formed into a section facing, the section facing having the longitudinal edges shaped into stile-receiving first and second channels and with longitudinal ribs formed between the channels;
- end stiles for securement to the section facing in the stile-receiving channels, the end stiles being fabricated from sheet metal into a modified C configuration including a front face, a side wall, and a rear face, the front face being placed into juxtaposition with the outside face of the section facing with the end of the section facing engaged inside the end stile;
- and
- an angle support received inside the end stile in juxtaposition with the ribs of the section facing and secured to the ribs and to the side wall of the end stile.
An overhead door section system comprising:
- a section facing fabricated from a generally rectangular sheet of metal and folded along the longitudinal edges into top and bottom edge channels and having longitudinally formed ribs in the body of the section facing;
- an end stile secured to the section facing at each end of the panel, each end stile comprising a longitudinal element fabricated from sheet metal and bent longitudinally into a front face, a perpendicular side wall and a rear face parallel to and spaced from the front face, the end stile being received between the top and bottom edge channels with the front face of the end stile overlapping the end of the section facing;
- an angle support received inside the end stile with the angle support placed in juxtaposition across the ribs of the section facing to hold the end of the section facing against the inside front face of the end stile, the angle support including securement means for securing the angle support to the sidewall of the end stile and to the ribs of the section facing;
- and
- a back facing for the panel, the back facing being formed from a sheet of metal and secured to the rear face of the overhead door section with the longitudinal edges of the back facing received inside the channels and secured to the rear face of the end stiles and providing a truss effect to the overhead door section.
An overhead door system comprising:
- a plurality of overhead door sections, each overhead door section comprising:
- a substantially rectangular sheet of metal formed into a section facing, the section facing having the longitudinal edges shaped into stile-receiving first and second channels and with longitudinal ribs formed between the channels;
- end stiles for securement to the section facing in the end of the stile-receiving channels, the end stiles being fabricated from sheet metal into a modified C configuration including a front face, a side wall, and a rear face, the front face being placed into juxtaposition with the outside face of the section facing with the end of the section facing engaged inside the end stile;
- an angle support received inside the end stile in juxtaposition with the ribs of the section facing and secured to the ribs and to the side wall of the end stile, to clamp the end of the section facing against the front face of the end stile;
- and
- at least one center stile, the center stile being fabricated substantially similar to the end stiles but with less thickness so as to be received between the channels and in juxtaposition with the ribs;
- and
- hinge means for hingedly joining a plurality of overhead door sections in a side-by-side relationship with the hinge means being anchored to the overhead door sections at the end stiles and the center stile while clamping a portion of the channels against the end stiles and the center stile.
