WINDOW CURTAIN, CONTROL THEREOF MODULE AND OPERATING METHOD THEREOF Russian patent published in 2016 - IPC E06B9/322 

FIELD: household equipment.

SUBSTANCE: disclosed is a control module for window curtains. Said module comprises first drive axle and second drive axle, first drive axle is driven to control vertical movement of lower part of window curtains and second drive axle is driven for adjustment of inclination of multiple lamellae window curtains, sleeve attached to first drive axle transfer part connected to the second drive axle retainer assembled around first driving axis, stopper has a locking state in which stop blocks rotary movement of bushing and first driving axis to maintain lower part in required position, and unlocking state wherein there is possibility of rotation of bushing and first driving axis so that lower part is lowered by gravity, and releasing assembly including actuator, actuator is operably connected with retainer and has elongated shape extending substantially vertically, which sets longitudinal axis, actuator is driven to move along longitudinal axis of first position into second position to switch stopper from locking state to unlocking state, and actuator in first position, is driven to rotate second drive axle by means of transfer part. Also disclosed is a window curtain. Module comprises a top track, a plurality of lamellae, a bottom part disposed under lamellae, at least one unit for winding cord, which includes a housing and a drum for winding and a rotating part, respectively assembled rotatably in housing, at least one suspension cord and ladder assembly cord while hanging cord connected to drum for winding up and lower part, and ladder assembly cable is connected to rotating part, lamellae and lower portion, and a control unit described above, wherein control module is assembled in upper track at a location remote from cord winding assembly, first drive control unit is connected to axle of winding drum, and a second drive control unit is connected to axis of rotating part.

EFFECT: also disclosed is a method of operating window curtain, in which window curtain comprises top track, bottom part, multiple lamellae between top track and lower part, suspended cord is connected with lower part and with drum to wind, landing cord assembly connected with bars and rotating part, and control module, control module includes first and second drive axle retainer, working cord and actuator with elongated shape extending vertically, which sets longitudinal axis, he method comprises providing downward pulling action on actuator from first position into second position to switch retainer of locking state, locking rotation of first drive axle in unlocking state, ensuring possibility of rotation of first drive axle by means of which lower part of lowered gravity when lower part reaches required height, release of actuator is performed so that actuator is moved upward for recovery of first position when actuator is in first position, rotation actuator is performed around longitudinal axis for adjustment of inclination and provision of pulling action on suspended cord to lift lower part.
