Title:
DRIVING MECHANISM FOR ROLL BLIND CAPABLE OF LIGHTING ADJUSTMENT
Document Type and Number:
WIPO Patent Application WO/2019/045361
Kind Code:
A1
Abstract:
The present invention relates to a driving mechanism for a roll blind capable of lighting adjustment, the driving mechanism comprising: a cover housing (212) having a stopper (212c) formed to protrude; a driving shaft (213a) coupled to the cover housing (212) to be able to rotate relative thereto; a twisting coil spring (220) wound and tightened around the outer peripheral surface of the driving shaft (213a); and a clutch wheel (223) that rotates integrally with the driving shaft (213a), wherein, when the driving shaft (213a) engages with the stopper (212c) in the rotating process, rotation of the twisting coil spring (220) is blocked thereby; the driving shaft (213a) nevertheless can keep rotating even when rotation of the twisting coil spring (220) is blocked; the driving mechanism further comprises a tilting gear (222) that engages with the twisting coil spring (220) and rotates together with the same, and a tilting wheel (224) that is interlocked with the tilting gear (222) via an idle gear (218) and is rotated accordingly; and the tilting wheel (224) is rotated by rotation of the twisting coil spring (220) in a range where the twisting coil spring (220) rotates together with the driving shaft (213a) without engaging with the stopper (212c). Accordingly, lighting adjustment is made possible without lifting or lowering a weight, and noise generation can be reduced.
