  • Patent number: 4683932
    Abstract: A rolling shutter includes a winding and/or unwinding shaft for a sectional structure consisting of blades provided with a catch mechanism engageable by a driving mechanism rotatably rigid with a second shaft disposed downstream of the winding shaft and held by lateral flanges of the shutter housing. The shutter further includes guide rails slidably engaged by the lateral ends of the blades. The second shaft includes at either end a driving mechanism having a backlach consistent with the variable pitch existing between the catch mechanism of two adjacent blades. The driving mechanism is adapted to be actuated by a motor for causing the rotation of the winding shaft in one or the other direction.
