US 2026/0146500 A1 · SYSTEM, ASSEMBLY, AND METHOD FOR ROLLING A SHUTTER CURTAIN

Abstract

A system and method to reduce a roller shutter box depth in a roller shutter system, the roller shutter system comprising a roller shutter box; a roller shutter curtain comprising a plurality of slats; and a plurality of shafts parallel each other, horizontally installed in the roller shutter box, located on an upper part of the roller shutter system and at least operational to hold the rolled shutter curtain; wherein at least one shaft is operational to rotate around its axis-of-rotation; and wherein adjacent shafts of the plurality of shafts are separated by a vertical gap, the method comprising: rolling the roller shutter curtain along a curved outline shell surface bounded by outer limits of the plurality of shafts and the rolled curtain. The rolling along the curved outline shell surface may be instrumental in reducing the roller shutter box depth.
