Component for producing a sectional door panel, shell for such a component, reinforcement strut for such a component, sectional door panel having such a component, and sectional door having a corresponding sectional door panel

摘要

A structural element for the fabrication of a panel of a sectional door, which is movable between a closed and an open position along a predetermined pathway. The sectional door possesses a shell, generally of metal, having two mutually parallel sides, bent back on themselves, thus essentially creating structural elements aligned somewhat perpendicularly to the predetermined pathway. When in the closed position, the shell is characterized by forming an outer door surface which is external to the space to be closed, and forming an internal door surface opposed thereto.
