When the user selectively rotates the first and second blind wings 2100 and 2200 by separating the first and second regions 10 and 20 from each other, The shaft 100 can be rotated by driving the above-mentioned drive motor (not shown). When the shaft 100 is rotated, the first rotatable member 3310 rotates together with the first stopper 3350 provided on the first rotatable member 3310.

The first rotating member 3310 rotates and rotates together with the first stopper 3350 and the first wire 3210. At this time, the first stopper 3350 comes into contact with the stopper protrusion (not shown) which restricts the rotation by contacting with the stopper, and restricts the rotation.

Since the first blind wing 2100 is connected by the first wire 3210, when the first wire 3210 rotates, the first blind wing 2100 rotates in the horizontal direction in the vertical direction , The second blind wing 2200 does not rotate and maintains the vertical direction.

That is, the first blind wing 2100 rotates horizontally and opens, and the second blind wing 2200 is vertically closed. Thus, the first and second blind blades 2100 and 2200 are selectively rotatable and detachable.

At this time, the first rotary member 3310 rotates and the first planetary gear reduction portion 3410 of the gear reduction portion 3400 provided at one side of the first rotary member 3310 may rotate together . When the first rotary member 3310 rotates, the first sun gear portion 3411 of the first planetary gear reduction portion 3410 rotates and the first sun gear portion 3411 rotates to the first planetary gear portion 3411 3412 of the first gear portion 3430.

That is, in a state where the first ring gear portion 3414 is fixed, the first planetary gear portions 3412 rotate around the first sun gear portion 3411 and rotate together with the first gear rotation support portion 3413).

Since the first stopper 3350 is in contact with the contact stopper protrusion of the protective cover part when the first rotating member 3310 is extended by the shaft 100, The first wire 3210 can not be rotated. In this state, the engaging portion 3311 of the first rotating member 3310 rotates together and the engaging portion 3311 rotates together with the second sun gear portion 3421 of the second planetary gear reduction portion 3420 . The second sun gear portion 3421 is rotatably supported on the second sun gear portion 3421. The second sun gear portion 3421 is provided around the second sun gear portion 3421 to rotate the second sun gear portion 3421, Since the second planetary gear unit 3422 is engaged with the second sun gear unit 3421, when the second sun gear unit 3421 is rotated, the second sun gear unit 3421 is engaged with the second planetary gear unit 3422, .

That is, the second planetary gear units 3422 rotate along the circumference of the second sun gear 3421. When the second sun gear portion 3421 rotates twice, the second planetary gear portions 3422 are rotated one rotation along the circumference of the second sun gear portion 3421 while rotating organically with each other.

More specifically, when the second sun gear portion 3421 rotates in the counterclockwise direction, the second planetary gear portions 3422 rotate in a clockwise direction to reduce the number of rotations.

Thus, the second planetary gears 3422 decelerate the rotation speed and rotate the second rotary member 3320 at a reduced speed. The second planetary gear portion 3422 is coupled to the second gear rotation support portion 3423 protruding from one side of the second rotation member 3320 so that the reduced rotational speed of the second planetary gear portion 3422 And is transmitted to the second gear rotation support portion 3423 and rotated at a reduced speed. The second planetary gear reduction portion 3420 rotates the second rotary member 3320 sequentially by rotating the first rotary member 3310 after the first rotary member 3310 rotates first, The second stopper 3360 is rotated.

That is, when the second rotating member 3320 rotates at a reduced speed and the second rotating member 3320 rotates, the second stopper 3360 and the second wire 3220 rotate together. The first stopper 3350 of the first rotating member 3310 and the second stopper 3360 of the second rotating member 3320 are arranged in parallel with each other. Since the second wire 3220 is connected to the second blind wings 2200, the second wire 3220 rotates and the second blind wings 2200 of the second region 20 And the second blind wings 2200 rotate in the horizontal direction in the vertical direction. That is, the first and second blind blades 2100 and 2200 are all rotated in the horizontal direction.

In this state, when the shaft 100 is rotated in the opposite direction to the rotating direction, the first rotating member 3310 rotates in the opposite direction, the first stopper 3350 rotates in the opposite direction, To rotate the first blind wing 2100 in the vertical direction in the horizontal direction. At this time, only the first blind blades 2100 are rotated, and the second blind blades 2200 are not rotated. In this way, only the first blind blades 2100 can be selected and rotated separately.

When the first stopper 3350 is in contact with the contact stopper protrusion (not shown) of the protective cover portion and the first rotatable member 3310 rotates in the opposite direction to the extension, the first rotatable member 3310, The second rotating member 3320 rotates in the opposite direction. The second rotary member 3320 reduces the rotation speed of the first rotary member 3310 by the second planetary gear reduction portion 3420 and reduces the rotation speed. The second stopper 3360 also rotates at a reduced speed when the second rotating member 3320 rotates at a reduced speed, and the second wire 3220 also rotates at a reduced speed. The second wire 3220 is rotated at a reduced speed and the second blind wing 2200 is rotated in the vertical direction in the horizontal direction. That is, the first and second rotary members 3310 and 3320 sequentially rotate to rotate the first and second blind wings 2100 and 2200 in the horizontal direction.

When the first and second rotary members 3310 and 3320 are not rotated, the first and second wires 3210 and 3220 may be pulled and pulled by the user, (3410) and (3420).

The first and second planetary reduction gears 3410 and 3420 are engaged with the first and second planetary gear reduction portions 3412 and 3422 and the first and second sun gear portions 3411 and 3421, Therefore, when the first and second sun gear portions 3411 and 3421 are rotated by pulling the first and second wires 3210 and 3220 from the outside, the first and second planetary gear portions 3412 and 3422 The reduction gear ratio is large to prevent rotation of the first and second sun gear portions 3411 and 3421 so that the first and second wires 3210 and 3220 are not pulled.

That is, when the first and second blind blades 2100 and 2200 are rotated after being rotated vertically or horizontally, the rotation of the first and second blind blades 2100 and 2200 can be prevented by an external force.

The first and second planetary reduction gears 3410 and 3420 rotate the first and second rotary members 3310 and 3320 when the shaft 100 is rotated by a drive motor The first and second rotating members 3310 and 3320 are not rotated even when the first and second wires 3210 and 3220 are pulled.

Accordingly, the first and second planetary gear reduction portions 3410 and 3420 sequentially rotate the first and second rotary members 3310 and 3320 and sequentially rotate the first and second blind blades 2100 Preventing the first and second blind wings 2100 and 2200 from being rotated by an external force irrespective of the intention of the user, thereby improving the use of the product.

Those skilled in the art, who understands the spirit of the present invention, can readily suggest other embodiments by adding, changing, deleting, adding, or the like of components within the scope of the same idea, I would say.
