  • a frequent problem in designing a lifting shutter is that a large lifting torque is required because the shutter curtain is heavy. Since the electric motor for raising the shutter curtain occupies a small part of the overall cost of the raising shutter, it is difficult to use a high-power electric motor for economic reasons. For this reason, normally, a reduction mechanism with a large reduction ratio is used to obtain a large torque with a relatively small electric motor. As a result, the moving speed of the shutter curtain is much lower than the upper limit speed that is required to be lower than that for safety reasons. It was slower than necessary. However, the weight of the shutter curtain increases remarkably as the height and width of the shutter curtain increase. Therefore, the higher the shutter force is, the more slowly it moves up and down. Great deals ,. This has been a major limitation in using a large-scale lifting shutter.

Abstract

Volet roulant offrant d'excellentes performances de protection contre les incendies, capable d'être ouvert et fermé rapidement, et capable d'utiliser un rideau de fermeture de grande taille. Chaque latte (18) du rideau (12) de fermeture du volet roulant (10) est un élément de profilé en alliage d'aluminium présentant une forme prédéterminée en section droite. L'élément de profilé présente une paire de parois de faces latérales, une section de bord supérieur servant à relier ensemble des sections de bords latéraux du côté supérieur de la paire de parois de faces latérales et une section de bord inférieur servant à relier ensemble des sectionsde bords latéraux du côté inférieur de la paire de parois de faces latérales. Un labyrinthe (50) est formé par et entre la section (42) de bord inférieur de la latte supérieure parmi deux lattes verticalement adjacentes et la section (40) de bord supérieur de la latte inférieure. Par ailleurs, lorsque deux lattes verticalement adjacentes présentent des amplitudes différentes de déformation en flexion provoquées par une différence de température entre les deux faces latérales de chaque latte, aucun interstice n'est formé entre les deux lattes car la section de bord inférieur de la latte supérieure et la section de bord supérieur de la latte inférieure sont enclenchées ensemble.
