Abstract
Sectional door panels include formed metal or plastic skin parts with opposed upper and lower edges configured to form pinch resistant connections between adjacent panels. The skin part edges include spaced-apart slots for receiving locating flanges formed on opposed end stiles and one or more intermediate stiles to provide for the stiles to be positively located with respect to the panel skin part during assembly thereof. Snap together hinge parts are provided with bosses cooperating with slots formed in the stiles for positively locating the hinge parts with respect to the stiles and the skin part. Mechanical fasteners connect the hinge parts and the stiles to the skin parts. The hinge parts include cooperating pin and pin receiving bore portions with the bore portions being formed in part by elastically deflectable fingers whereby the hinge parts may be snapped together during assembly of the door by stacking one panel on top of another.
