DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slat drive device for pulling out or folding a slat of a vertical blind along a hanger rail.

[0002]

2. Description of the Related Art Conventionally, there are the following slat driving devices for vertical blinds. In order to move the slats along the hanger rail, in a vertical blind in which a drive shaft having a spiral groove is rotatably supported in the hanger rail, an operation cord hanging from one end of the hanger rail is operated. When the drive shaft rotates, the leading runner moves, and the subsequent runner moves with the movement of the leading runner.

Therefore, the slat can be pulled out or folded along the hanger rail based on the operation of the operation cord. In addition, in the case of a vertical blind in which an operation code is movably stretched in the hanger rail in order to move the slat along the hanger rail, the leading runner is fixed to the operation code.

[0004] When the operation code hanging from one end of the hanger rail is operated, the leading runner moves,
The subsequent runner moves with the movement of the leading runner.

Therefore, the slat can be pulled out or folded along the hanger rail based on the operation of the operation cord. By directly operating the leading slat, the slat can be pulled out or folded.

[0006]

In the vertical blind in which the slat is moved by moving the leading runner with the drive shaft as described above, the operation of moving the slat is performed near the center of the slat movement range. It is not possible and is only possible to operate the operating cord hanging on one side of the hanger rail.

[0007] Therefore, when performing the slat moving operation, the operator must go to one side of the hanger rail, so that there is a problem that the slat moving operation is complicated.

In a vertical blind in which the slat is moved by moving the leading runner with an operation cord, the slat can be pulled out or folded by directly pulling and operating the suspended slat from the leading runner. However, there is a problem that the frictional resistance due to the operation cord being routed in the hanger rail is large, and the operation force required for the slat moving operation is increased.

Further, if such an operation is continued, there is a problem that the operation cord in the hanger rail is slackened, and the slat cannot be reliably moved to a predetermined position when the slat is fully opened or closed.

[0010] It is an object of the present invention to provide a vertical blind in which the slat can be easily moved and operated with a small operation force by improving the degree of freedom of the operation position where the slat is moved. To provide.

[0011]

According to the present invention, a slat is suspended from a plurality of runners movably supported in a hanger rail, and an operation cord is connected to a leading one of the runners. By manipulating the operation code to move the leading runner, the subsequent runner is moved to enable the respective slats to be moved, and by manipulating the leading slat, the respective slats can be moved / operated. In the vertical blind slat drive device, one ends of the first and second operation cords are hung from one end of the hanger rail, and the first operation cord is hung on a guide roller at the other end of the hanger rail and inverted. The other end of the first operation code is connected to the leading runner, and the other end of the second operation code is connected to the leading runner. And sintering said slats and movable operation based on the first and second operation code of the operation was attaching a weight member to strain the operation code of the first to one end of said first operation code.

(First Embodiment) FIGS. 1 to 5
Shows a first embodiment in which the present invention is embodied in a double blind type vertical blind.

As shown in FIGS. 1 and 2, a large number of runners 2 are movably supported on a hanger rail 1, and slats 3 are suspended from each runner 2. An intermediate stopper 4 is fixed to a middle portion of the hanger rail 1 in the longitudinal direction.

The same number of runners 2 are provided on both sides of the intermediate stopper 4. On the left side of the intermediate stopper 4, a left front runner 2a is disposed at a position closest to the intermediate stopper 4, and a left front slat 3a is suspended from the runner 2a.

On the right side of the intermediate stopper 4,
A right front runner 2b is disposed at a position closest to the intermediate stopper 4, and a right front slat 3b is suspended from the runner 2b.

The left front runner 2a is an intermediate stopper 4
, The subsequent runners 2 connected by the spacers are sequentially pulled out toward the center of the hanger rail 1.

When the left front runner 2a moves toward the left end of the hanger rail 1, the subsequent runners 2 are sequentially pushed back in the same direction. Right top runner 2b
Moves toward the intermediate stopper 4, the subsequent runners 2 connected by the spacers are sequentially drawn out toward the center of the hanger rail 1.

When the right front runner 2b moves toward the right end of the hanger rail 1, the subsequent runners 2 are sequentially pushed back in the same direction. A gear box 5 is provided on the intermediate stopper 4 side of the left front runner 2a. As shown in FIG. 2, a worm mechanism including a worm 6 and a worm wheel 7 is built in the gear box 5. I have.

One end of the worm 6 is connected to the gear box 5
The input shaft 8 is configured to protrude downward from the input shaft 8.
An operation rod 10 is suspended and supported via a universal joint 9.

At the center of the worm wheel 7, a tilt shaft 11 having an axial spline engraved on the outer peripheral surface is fitted and inserted. The tilt shaft 11 is rotated integrally with the worm wheel 7. The tilt shaft 11 extends over the entire length of the hanger rail 1 and is fitted into each of the runners 2, 2a, 2b.

Each of the runners 2, 2a, 2b is movable along the tilt shaft 11, and the tilt shaft 11 is rotated by a known worm mechanism disposed in each of the runners 2, 2a, 2b. Then, the slats 3, 3a, 3b are rotated in the same phase.

Therefore, when the operating rod 10 is rotated, each slat 3, 3a, 3b is rotated in the same phase. A first operation code 12 is connected to the left head runner 2a and the right head runner 2b, and a second operation code 13 is connected to the left head runner 2a, and the operation codes 12, 13 are operated. By
Each head runner 2a, 2b can be moved.

The operation of the operation cords 12 and 13 in the hanger rail 1 will be described with reference to FIG. 4. A weight grip 14 is suspended from one end of the first operation cord 12.

The first operation cord 12 is guided into the hanger rail 1 via the guide roller 15 at the left end of the hanger rail 1, passes through the left front runner 2a, and is connected to the right front runner 2b.

Further, the first operation cord 12 is further guided to the right end of the hanger rail 1 and is guided by guide rollers 16.
And the other end is connected to the left front runner 2a through the right front runner 2b.

One end of the second operation cord 13 is connected to the left front runner 2a, and is suspended downward through the guide roller 17 at the left end of the hanger rail 1. And
As shown in FIG. 3, a grip 18 is suspended from the other end through the weight grip 14.

Therefore, when the weight grip 14 is pulled downward, the left front runner 2a and the right front runner 2b
Moves toward the intermediate stopper 4. At this time, the grip 18 is pulled upward with the movement of the left front runner 2a.

When the grip 18 is pulled downward, the left front runner 2a and the right front runner 2b move away from the intermediate stopper 4. At this time, the weight grip 14 is pulled upward.

Next, the operation of the vertical blind configured as described above will be described. When the weight grip 14 or the grip 18 is operated to move the slats 3, 3 a, 3 b on the left end side of the hanger rail 1, when the weight grip 14 is pulled down, the leading runners 2 a, 2 b become intermediate. It moves toward the stopper 4 and the subsequent runners 2 are sequentially pulled out.

Then, as shown in FIG. 5, when each of the leading runners 2a, 2b abuts on the intermediate stopper 4, further movement of the leading runners 2a, 2b is prevented. At this time, the grip 18 is automatically pulled upward.

In this state, the slats 3 are suspended and supported at equal intervals. Further, based on the dimensions of the gear box 5 and the intermediate stopper 4 attached to the left front runner 2a, the interval between the front slats 3a and 3b is set to be equal to the interval between the other slats 3. Then, the operation rod 10 is hung between the leading slats 3a and 3b.

When the grip 18 is pulled down, the leading runners 2a and 2b move away from the intermediate stopper 4, and the subsequent runners 2 are sequentially pushed back by the leading runners 2a and 2b.

Then, as shown in FIG. 1, each slat 3, 3a, 3b is folded at both ends of the hanger rail 1. Further, by operating the operating rod 10, the vertical blind can pull out and fold the slats 3, 3a, 3b.

That is, by operating the operating rod 10 to move the left front runner 2a toward the intermediate stopper 4,
The first operation code 12 tries to loosen between the leading runners 2a and 2b, but the slack is absorbed by the lowering of the weight grip 14, and the right leading runner 2b moves toward the intermediate stopper 4.

Therefore, each slat 3, 3a, 3b is pulled out toward the center of the hanger rail 1. Also,
When the operating rod 10 is moved toward the left end side of the hanger rail 1, the subsequent runners 2 are sequentially pushed back by the left front runner 2a, and the right front runner 2b.
Moves to the right end side of the hanger rail 1, and the subsequent runners 2 are sequentially pushed back.

Accordingly, the slats 3, 3a, 3b are folded at both ends of the hanger rail 1. At this time, the weight grip 14 goes up, and the grip 18 goes down.
The vertical blinds can be pulled out and folded by operating the leading slats 3a, 3b.

That is, when any one of the leading slats 3a and 3b is moved toward the center of the hanger rail 1, the slat can be pulled out as in the case of operating the operating rod 10.

When the left front slat 3a is moved to the left end side of the hanger rail 1, each slat 3 can be folded in the same manner as when the operation rod 10 is operated, and the right front slat 3b is moved to the hanger rail 1. Is moved to the right end of the slat 3b following the first slat 3b.
Is folded to the right end side of the hanger rail 1.

At this time, if the left leading slat 3a is moved to the left end of the hanger rail 1, the succeeding slat 3 is reliably folded to the left end of the hanger rail 1. When the operating rod 10 is rotated, the tilt shaft 11 is rotated, and the slats 3, 3a, 3b are angle-adjusted in phase based on the rotation of the tilt shaft 11.

With the vertical blind constructed as described above, the following effects can be obtained. (1) By rotating the operation rod 10, each slat 3, 3
The angles of a and 3b can be adjusted in the same phase regardless of their positions.

(2) The operator operates the weight grip 14 or the grip 18 at the left end position of the hanger rail 1 so that the slats 3, 3a, 3
b can be pulled out or folded. Also, the weight grip 14 or the grip 18
By pulling down, the slats 3, 3a, 3b can be easily pulled out and folded.

(3) By operating one operating rod 10, the operator can move the operating rod 10 at the position of the left front runner 2 a.
The slats 3, 3a, 3b can be pulled out or folded.

(4) By operating the leading slats 3a, 3b, the operator can pull out or fold the slats 3, 3a, 3b at the positions of the leading slats 3a, 3b.

(5) Between the leading slats 3a and 3b, 1
Since only the operation rod 10 is suspended, it is easy to make the interval between the leading slats 3a and 3b equal to the interval between the other slats 3. Also, the leading slat 3a,
Since the interval between the slats 3b can be made equal to the interval between the other slats 3, when the slats 3, 3a and 3b are fully closed, it is possible to prevent the occurrence of a gap between the leading slats 3a and 3b. it can.

(6) The first operation cord 12 is tensioned by the weight of the weight grip 14, and the slats 3, 3
Each slat can be reliably moved at the time of the fully closing operation and the fully opening operation of a and 3b.

(7) Since the first operation cord 12 is mounted on the guide roller 16 acting as a fixed pulley,
The operation force acting on the first operation code 12 acts equally on each of the leading runners 2a, 2b. Therefore, the moving operation of each of the slats 3, 3a, 3b can be performed with a small operation force. (Second Embodiment) FIG. 6 shows the routing of operation codes when changing the double blind type vertical blind of the above-mentioned embodiment to a single opening vertical blind.

The single blind type vertical blind has one leading runner 19. After penetrating the first runner 19, the first operation code 12 is inverted by the guide roller 16 and its end is connected to the first runner 19.
