Abstract

A roller shutter winding lifting device comprising: a roller shutter support plate assembly (A) including a roller shutter winding bar connection (5) and on the inside three planetary gears 1, cooperating peripherically with a fixed toothed rim (D) and axially inside with a toothed pinion (14) of a driving clutch assembly (B) provided with a driving pulley (11) and a clutch device (20, 21, 14 min ) cooperating with a free ratched wheel (18, 9), being said assembly (B) tightened and supported by a mounting plate (C) in such a way that: rotating the driving pulley (11) in one direction the friction (20, 21, 14 min ) locks tightening the free ratchet wheel (19) allowing the free wheel movement transmission by means of the pinion (14), through planetary gears (11) and toothed rim (D) in reduced rotation of the roller shutter connection (5) in the same direction; whereas rotating the driving pulley (11) in the opposite direction the clutch device (20, 21, 14 min ) is unclutched allowing the controlled rotation of the connection (5) for unwinding the roller shutter in the same direction, and this by means of a multi-start screw thread (15) which causes the clutching or unclutching of said free wheel clutch device (20, 19, 21, 14 min ).
