A sectional door, which may be an overhead door (10) such as a residential garage door, including hingedly connected door panels (12a-12d) each being formed from a plurality of subpanels (14a-14d). The subpanels (14a-14d) forming each door panel (12a-12d) are disposed end-to-end to form the entire length of the door panel (12a-12d). Rigid connection between adjacent subpanels (14a-14d) of the same door panel (12a-12d) is made by at least one and preferably two connecting bars (32) extending within channels (34, 36) of adjacent subpanels (14a-14d) in a lengthwise direction. The connecting bars (32) are each formed of a length substantially less than the overall length of the door panel (12a-12d) but slightly longer than the length of an individual subpanel (14a-14d). All components of the door (10) may be stored and transported in relatively small packages or cartons (100), yet may be assembled into a structurally rigid, wind resistant sectional door (10).

Porte en sections, qui peut être une porte à déplacement vertical (10) telle que porte de garage d'habitation, comportant des panneaux de porte (12a-12d) reliés par articulation, chacun étant formé d'une pluralité de sous-panneaux (14a-14d). Les sous-panneaux (14a-14d) formant chaque panneau de porte (12a-12d) sont disposés bout à bout pour former la longueur totale du panneau de porte (12a-12d). Un lien rigide entre sous-panneaux adjacents (14a-14d) d'un même panneau de porte (12a-12d) est assuré au moyen d'une, de préférence deux, barres de raccordement (32) qui s'étendent dans le sens de la longueur à l'intérieur de rainures (34, 36) ménagées dans des sous-panneaux adjacents (14a-14d). Ces barres de raccordement (32) ont chacune une longueur sensiblement inférieure à la longueur totale du panneau de porte (12a-12d), mais légèrement supérieure à la longueur d'un sous-panneau pris individuellement (14a-14d). Tous les éléments de la porte (10) peuvent être stockés et transportés dans des emballages ou des cartons relativement peu volumineux (100), mais peuvent par contre être montés pour donner une porte en sections (10) structurellement rigide, ayant une bonne stabilité au vent.
