As shown in figure 12, on the bottom surface of above-mentioned transmission dish 64a, be formed with the recess 72 of the teat 71b that can accommodate transmission dish 64b, and, in this recess 72, be formed with the teat 73 connecting with above-mentioned teat 71b.Teat 73 is formed on respect to transmitting Pan64a center and is in the scope of 25 degree.
On the bottom surface of above-mentioned transmission dish 64b, be formed with the recess 74 of the teat 69 that can accommodate above-mentioned conversion belt wheel 65, and, in this recess 74, be formed with the teat 75 connecting with above-mentioned teat 69.Teat 75 is formed on respect to transmitting Pan64b center and is in the scope of 25 degree.
As shown in Figure 4, in above-mentioned conversion gear 63, a side at above-mentioned central axis 67 is formed with downward outstanding teat 76, and this teat 76 is formed on respect to conversion gear 63 center and is in the scope of 45 degree, and is positioned in same rotary motion trace with the teat 71a of above-mentioned transmission dish 64a.
By above-mentioned formation, conversion belt wheel 65 and conversion gear 63 are supported in the mode that can rotate on the support tube 66 of housing 32, and the central axis 67 that transmission dish 64a, 64b are converted gear 63 in the mode that can rotate is supported.
And when the rotation along with above-mentioned pitch gear 36 and conversion gear 63 while being also rotated, after the teat 76 of conversion gear 63 and the teat 71a of transmission dish 64a connect, conversion gear 63 and transmission dish 64a are integratedly and are rotated.
In addition, when transmission dish 64a and conversion gear 63 are while being rotated integratedly, after the teat 73 at the back side (bottom surface) of transmission dish 64a and the teat 71b of transmission dish 64b connect, conversion gear 63 and transmission dish 64a, 64b are integratedly and are rotated.
In addition, when conversion gear 63 and transmission dish 64a, 64b are while being rotated integratedly, after the teat 75 at the back side (bottom surface) of transmission dish 64b and the teat 69 of conversion belt wheel 65 connect, conversion gear 63 is integratedly and is rotated with transmission dish 64a, 64b and conversion belt wheel 65.
By moving as described above, when the direction of rotation of conversion gear 63 becomes when reverse, after conversion gear 63 has rotated more than predetermined angular, the rotation of conversion gear 63 is passed to conversion belt wheel 65.And, this predetermined angular is set to and surpasses following angle:, in the above-mentioned angular adjustment axle 16 rotations angle that roughly conversion gear 63 rotates a week time, in other words, at above-mentioned blade 3, from complete closure state, turn to reverse complete closure state during internal conversion gear 63 angle of rotating.
As shown in figure 13, on above-mentioned conversion belt wheel 65, hanging installation (mounting) has above-mentioned hauling rope 6, and the rotation by conversion belt wheel 65 moves around hauling rope 6 in above-mentioned hanger rail 1 thus.
Then, the effect of the operating means 4 of above-mentioned such vertical blind forming is described.
At each blade 3 hanging down from hanger rail 1, with respect to hanger rail 1 rectangular opening the state that form is carried out suspension strut of direction for example, while operating of pelletron 5 downwards, belt wheel 34 is rotated.
The rotation of belt wheel 34 is passed to pitch gear 36 from operation gear 33 through transmitting gear 35.Along with the rotation of pitch gear 36, conversion gear 63 is also rotated, and still, the impact due to the transport delay unit action consisting of transmission dish 64a, 64b and conversion belt wheel 65, makes to change belt wheel 65 and can not rotate immediately.
Along with the rotation of pitch gear 36, inclination clutch 38 is also rotated, and inclination clutch shaft 45 is also integratedly and is rotated with inclination clutch 38.
As shown in Figure 9, when making clutch, the rotation by inclination clutch shaft 45 carries out an end in one end of sheet 50 and end 62a, the 62b of clutch spring 61 while connecting, friction between clutch spring 61 and clutch ring 59 increases, thereby the rotation of inclination clutch shaft 45 is passed to sloping shaft 53 via clutch spring 61 and clutch ring 59.
So angular adjustment axle 16 is rotated, thereby suspension strut is rotated in the blade 3 of each pulley 2,2a.
When turning at each blade 3 under the state that is complete closure state or reverse complete closure state, while further wanting to make angular adjustment axle 16 to same direction rotation to same direction operation pelletron 5, in each pulley 2,2a, the limiting unit 21 that is rotated of suspended axle 12 connects with the rotation limiting unit 22 of bearing portion 13, thereby stops suspended axle 12 rotations.So, under the state that worm gear 14 occurs to rub in the friction generating unit 23 with suspended axle 12, being rotated, the torque that therefore acts on angular adjustment axle 16 increases.
Like this, the engaging recessed part 42 of inclination clutch 38 departs from from the engaging teat 49 of inclination clutch shaft 45, thereby inclination clutch 38 slides vertically and becomes the state shown in Fig. 7 from the state shown in Fig. 6.
And inclination clutch 38 rotates relatively with respect to inclination clutch shaft 45, and as shown in figure 10, an end in end 62a, the 62b of the clutch of inclination clutch 38 releasing sheet 43 and clutch spring 61 connects.
Thus, the friction between clutch spring 61 and clutch ring 59 reduces, thereby clutch spring 61 turns in the enterprising line space of outer peripheral face of clutch ring 59.Therefore, the rotation of inclination clutch 38 is not passed to sloping shaft 53.
When turning at each blade 3 under the state that is complete closure state or reverse complete closure state, while further pulling pelletron 5 to same direction, the rotation that becomes conversion gear 63 is passed to the state of conversion belt wheel 65.And by the rotation of conversion belt wheel 65, hauling rope 6 moves around and guide pulley 2a is moved in hanger rail 1, thereby carry out pulling out of blade, operate or folding operation.
When during to reverse operation pelletron 5, revert to the state that makes sloping shaft 53 rotations by the rotation of pitch gear 36 after desired position is pulled out or be folded to blade 3, make thus 16 rotations of angular adjustment axle, thereby each blade 3 is rotated.
The active force that switches spring 44 also can be set to: when all turning at all blades 3 when being complete closure state or oppositely pelletron 5 being rotated to same direction after complete closure state, make the engaging between clutch 38 and inclination clutch shaft 45 to be removed.
But, the active force that switches in the present embodiment spring 44 is set as: when surpassing the blade 3 of half sheet number of total leaf number amount, turn to when being complete closure state or oppositely pelletron 5 being rotated to same direction after complete closure state, make the engaging between clutch 38 and inclination clutch shaft 45 to be removed.
By above-mentioned formation, as shown in Figure 1, at many first blade group G1 of sheet number and sheet number, be less than the angle of the second blade group G2 Leaf 3 of the first blade group G1 when different, the operation described in being implemented as follows.
That is, towards first making the first blade group G1 become the direction moving blade 3 of complete closure state or reverse complete closure state, thereby make the first blade group G1 be complete closure state or reverse complete closure state.Now, the second blade group G2 is not rotated and is complete closure state or reverse complete closure state.
Then, blade 3 is rotated backward, and make the second blade group G2 first become complete closure state or reverse complete closure state.Then, further to same direction operation pelletron 5, make blade 3 rotate, thereby the first blade group G1 is turned to and is complete closure state or reverse complete closure state, make thus the angle of all blades 3 all consistent.
Now, only in the pulley 2 of the second blade group G2, make worm gear 14 be idling conditions with respect to suspended axle 12, thereby the torque that acts on angular adjustment axle 16 can significantly not increased.Therefore, the fastening state between inclination clutch 38 and inclination clutch shaft 45 is maintained, thereby can carry out the rotating operation of the blade 3 of the first blade group G1.
Required operating physical force while making the angle of all blades 3 consistent by set switching as described above the active force of spring 44, can alleviating.
