Abstract: An overhead door reinforcement assembly has a plurality of elongated reinforcing members operatively mounted vertically on the inner surface of the door between the top edge and the bottom edge of each of the several door panels, and a plurality of cap members overlying the adjacent ends of the reinforcing members. Pivot members pivotally connect the cap members to the adjacent ends of the reinforcing members, and this permits pivoting of the panels as the door is moved between open and closed positions, but prevents pivoting of the ends of the reinforcing members in the direction of the cap members to prevent buckling of the associated door in the closed position under externally applied pressure. A disengageable lock member is engaged with the cap members and the ends of the reinforcing members to prevent pivoting of the ends of the reinforcing members away from the cap members to prevent buckling of the door panels.

Abstract: A door has a pair of spaced stiles at its side edges, a top rail extending between the upper ends of the rails, and a pair of synthetic resin skins providing the faces of the door and adhesively bonded to the stiles and rail. The skins have opposed flanges along their top and bottom edges which abut to form top and bottom peripheral walls, and they also have opposing spaced lips along the side edges thereof which extend along a portion of the outer surfaces of the stiles. The peripheral walls provided by the flanges have vent openings extending therethrough, and a cellular synthetic resin core is bonded to the skins and fills the interior space between the skins bounded by the stiles, rail and bottom flange. Baffled passages are provided between the vent openings and the interior space. In making She door, after the skins have been assembled and adhered to the stiles and rails, the stiles and flanges effectively seal the interior space which they define and this assembly is placed in a heated press.
