However, this invention patent application only discloses the combined structure of the combined louver and the sunshade and light guide effect of the relative lifting and turning of the louver, and does not disclose the transmission mechanism related to the combined louver
[0004] Traditional blinds generally only need a transmission mechanism that completes the two actions of lifting and turning in a unified manner, while combined shutters generally require at least two transmission mechanisms for more than two actions, and the transmission mechanism that completes the two actions of lifting and turning traditional blinds generally only needs one The hexagonal shaft drives several reels to rotate at the same time, thereby driving the shutter blades to turn over, so only a bead chain or rocker is needed for operation, so the transmission mechanism of the combined shutter should also follow this habit and be able to complete the above Described action, however so far there is no transmission mechanism for such combined shutters

Embodiment Construction
[0054] The louvers of variable-pitch combined louvers are divided into main louvers and secondary louvers. There is at least one secondary louver between the two main louvers. The initial positions of all the main and secondary louvers are horizontal, so that there are three secondary louvers. As an example, an opening and closing motion cycle of a variable-pitch combined shutter with three secondary louvers: (1) The main and secondary louver blades 9 and the bottom rail 100 of the shutter descend as a whole until the main bottom rail 110 reaches the window sill. When the main louver blades 90 are equidistantly distributed on the window, the secondary louver blades 91, 92, 93 are stacked on the main louver blade 90 (corresponding to Figure 32a ), (2) The level of the second hundred blades 91 relative to the main shutter blades 90 rises distance, the second two hundred blades 92 and the second two hundred blades 92 are still superimposed on the main shutter blades 90 (corresp...

The invention relates to a blind window, in particular to a lifting turner for the blind window. The lifting turner for the blind window comprises a pedestal and a top cover, wherein a planetary gear clutch, a lifting wheel, a locking device, a planetary gear reducer, a winding wheel mechanism and a turning mechanism are arranged in the pedestal and the top cover and are axially installed on the pedestal in turn; the locking device which has the clutch locking action is arranged between the lifting wheel and the winding mechanism, so that the interactive relationship of the lifting wheel and the winding mechanism that one piece moves while the other piece stands can be realized; and the planetary gear reducer is arranged between the lifting wheel and the winding mechanism, so that the rotary speed that the hollow shaft of the planetary wheel frame of the planetary gear clutch is transmitted to the winding wheel mechanism can be reduced, and the tuning function that the louvre blades are slowly lifted can be met through the rotary speed of the winding wheel mechanism.
Description
technical field [0001] The invention relates to a shutter, in particular to a lifting and turning device for the shutter. Background technique [0002] The traditional blinds are composed of louver blades with an arc-shaped cross section, lift ropes, ladder belts, top rails and bottom rails. A rotary drive with self-locking function, a rotating shaft, and several winding lifts are installed in the top rail. The rope and the reel of the ladder belt are controlled. The rotating shaft passes through the rotary driver and the reel. A ladder belt is arranged between the top rail and the bottom rail. The lower end of the ladder belt is fixedly connected with the bottom rail. On the reel, a plurality of louvers arranged in parallel are worn in the horizontal cable of the ladder belt. A perforation is set at the symmetrical center of the cross section of the louver to allow the lifting rope to pass through. The lower end of the lifting rope is fixedly connected with the bottom rail....
