Abstract
A hemmed edge overhead garage door section having a face, a top rail integral with the face formed longitudinally therealong, the top rail having at least a top rail body extending rearwardly from the face and a top rail leg extending downwardly from the top rail body offset from the face, the top rail body and at least a portion of the top rail leg being thicker than the face, and a bottom rail integral with the face formed longitudinally therealong opposite of the top rail, the bottom rail comprising at least a bottom rail body extending rearwardly from the face and a bottom rail leg extending upwardly from the bottom rail body offset from the face, the bottom rail body and at least a portion of the bottom rail leg being thicker than the face.
Claims20
A hemmed edge overhead garage door section, comprising:
- a face;
- a top rail integral with the face formed longitudinally therealong and contiguous therewith, the top rail comprising at least a top rail body extending rearwardly from the face, a top rail leg extending downwardly from the top rail body offset from the face, and a top rail foot extending forwardly from the top rail leg toward the face;
- and
- a bottom rail integral with the face formed longitudinally therealong and contiguous therewith opposite of the top rail, the bottom rail comprising at least a bottom rail body extending rearwardly from the face, a bottom rail leg extending upwardly from the bottom rail body offset from the face, and a bottom rail foot extending forwardly from the bottom rail leg toward the face,
- wherein the face and the top and bottom rails thereof are formed integrally of a single material and define a full depth of the hemmed edge overhead garage door section,
- wherein the top rail foot terminates forwardly in a top rail foot bend of the single material, the top rail further comprising a top rail foot layer lying along and adjacent to the top rail foot, a top rail leg layer lying along and adjacent to the top rail leg, and a top rail body layer lying at least partially along and adjacent to the top rail body,
- wherein the bottom rail foot terminates forwardly in a bottom rail foot bend of the single material, the bottom rail further comprising a bottom rail foot layer lying along and adjacent to the bottom rail foot, a bottom rail leg layer lying along and adjacent to the bottom rail leg, and a bottom rail body layer lying at least partially along and adjacent to the bottom rail body,
- wherein the top and bottom rails are formed continuously with the face from the single material such that in the formed top rail the top rail body layer comprises a top edge of the single material lying along and adjacent to the top rail body and oriented extending forwardly toward the face and wherein in the formed bottom rail the bottom rail body layer comprises a bottom edge of the single material lying along and adjacent to the bottom rail body and oriented extending forwardly toward the face, and
- wherein in the resulting hemmed edge overhead garage door section the face is thinner than at least a portion of the top and bottom rails.
A hemmed edge overhead garage door section, comprising:
- a face;
- a top rail integral with the face formed longitudinally therealong, the top rail comprising at least a top rail body extending rearwardly from the face, a top rail leg extending downwardly from the top rail body offset from the face, and a top rail foot extending forwardly from the top rail leg toward the face, the top rail foot terminating forwardly in a top rail foot bend, the top rail further comprising a top rail foot layer lying along and adjacent to the top rail foot and still further comprising a top rail leg layer lying at least partially along and adjacent to the top rail leg;
- and
- a bottom rail integral with the face formed longitudinally therealong opposite of the top rail, the bottom rail comprising at least a bottom rail body extending rearwardly from the face, a bottom rail leg extending upwardly from the bottom rail body offset from the face, and a bottom rail foot extending forwardly from the bottom rail leg toward the face, the bottom rail foot terminating forwardly in a bottom rail foot bend, the bottom rail further comprising a bottom rail foot layer lying along and adjacent to the bottom rail foot and still further comprising a bottom rail leg layer lying at least partially along and adjacent to the bottom rail leg,
- wherein the face and the top and bottom rails thereof are formed integrally of a single material, whereby the top rail foot and the top rail foot layer, at least a portion of the top rail leg and the top rail leg layer, the bottom rail foot and the bottom rail foot layer, and at least a portion of the bottom rail leg and the bottom rail leg layer each together define a thickness that is double that of the face,
- wherein the top rail foot and the bottom rail foot each extends forwardly such that each of the top and bottom rail foot bends is in contact with the face, whereby the top and bottom rails are boxed,
- wherein the top and bottom rails are formed continuously with the face from the single material such that in the formed top rail the top rail leg layer comprises a top edge of the single material lying along and adjacent to the top rail leg and wherein in the formed bottom rail the bottom rail leg layer comprises a bottom edge of the single material lying along and adjacent to the bottom rail leg, and
- wherein in the resulting hemmed edge overhead garage door section the face is thinner than at least a portion of the top and bottom boxed rails.
A hemmed edge overhead garage door section, comprising:
- a face;
- a top rail integral with the face formed longitudinally therealong, the top rail comprising a top rail body extending rearwardly from the face, a top rail leg extending downwardly from the top rail body offset from the face, a top rail foot extending forwardly from the top rail leg toward the face, a top rail foot layer lying along and adjacent to the top rail foot, a top rail leg layer lying along and adjacent to the top rail leg, and a top rail body layer lying at least partially along and adjacent to the top rail body;
- and
- a bottom rail integral with the face formed longitudinally therealong opposite of the top rail, the bottom rail comprising a bottom rail body extending rearwardly from the face, a bottom rail leg extending upwardly from the bottom rail body offset from the face, a bottom rail foot extending forwardly from the bottom rail leg toward the face, a bottom rail foot layer lying along and adjacent to the bottom rail foot, a bottom rail leg layer lying along and adjacent to the bottom rail leg, and a bottom rail body layer lying at least partially along and adjacent to the bottom rail body,
- wherein the top and bottom rails are formed continuously with the face from a single material such that in the formed top rail the top rail body layer comprises a top edge of the single material lying along and adjacent to the top rail body and oriented extending forwardly toward the face and wherein in the formed bottom rail the bottom rail body layer comprises a bottom edge of the single material lying along and adjacent to the bottom rail body and oriented extending forwardly toward the face, whereby the top rail foot and the top rail foot layer, the top rail leg and the top rail leg layer, the top rail body and the top rail body layer, the bottom rail foot and the bottom rail foot layer, the bottom rail leg and the bottom rail leg layer, and the bottom rail body and the bottom rail body layer each together define a two-ply thickness of the single material that is double the single-ply thickness of the single material of the face, and
- wherein fasteners directly secure the top rail body with the top rail body layer therealong and the bottom rail body with the bottom rail body layer therealong.
