Description

[0001]
BACKGROUND 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]
[Prior art]
Conventional vertical slat drive devices include the following.
In order to move the slats along the hanger rail, in the vertical blind, in which the drive shaft with a spiral groove is rotatably supported in the hanger rail, the operation cord suspended from one end of the hanger rail is operated. When the drive shaft is rotated, the leading runner moves, and the subsequent runner moves as the leading runner moves.
[0003]
Therefore, the slat can be pulled out or folded along the hanger rail based on the operation of the operation cord.
Further, in a vertical blind in which an operation cord is movably stretched in the hanger rail in order to move the slat along the hanger rail, a leading runner is fixed to the operation cord.
[0004]
When the operation code suspended from one end of the hanger rail is operated, the leading runner moves, and the subsequent runner moves as the leading runner moves.
[0005]
Therefore, the slat can be pulled out or folded along the hanger rail based on the operation of the operation cord. It is also possible to perform a slat drawing operation or a folding operation by directly operating the leading slat.
[0006]
[Problems to be solved by the invention]
In the vertical blind that moves the slat by moving the leading runner with the drive shaft as described above, the slat movement operation cannot be performed near the center of the movement range of the slat, and it is placed on one side of the hanger rail. This is possible only by operating the operation code that is suspended.
[0007]
Therefore, when the slat moving operation is performed, the operator must always go to one side of the hanger rail, and thus there is a problem that the slat moving operation becomes complicated.
[0008]
With the vertical blind that moves the slat by moving the top runner with the operation cord, the slat can be pulled out or folded by directly pulling and operating the slat supported from the top runner. There is a problem in that the frictional resistance due to being drawn around the hanger rail is large, and the operation force required for the movement operation of the slats is increased.
[0009]
Further, if such an operation is continued, there is a problem that the operation cord in the hanger rail is loosened, and the slat cannot be reliably moved to a predetermined position when the slat is fully opened or fully closed.
[0010]
SUMMARY OF THE INVENTION An object of the present invention is to provide a vertical blind capable of improving the degree of freedom of the operation position for moving a slat, enabling the slat to be easily moved and operated with a slight operating force. It is in.

DETAILED DESCRIPTION OF THE INVENTION
(First embodiment)
1 to 5 show a first embodiment in which the present invention is embodied in a double-opening type vertical blind.
[0016]
As shown in FIGS. 1 and 2, a large number of runners 2 are movably supported on the hanger rail 1, and slats 3 are suspended from the runners 2. An intermediate stopper 4 is fixed to an intermediate portion in the longitudinal direction of the hanger rail 1.
[0017]
The same number of runners 2 are arranged 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 and supported by the runner 2a.
[0018]
Further, 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 and supported by the runner 2b.
[0019]
When the left front runner 2a moves toward the intermediate stopper 4, the subsequent runners 2 connected by the spacer are sequentially drawn out toward the center of the hanger rail 1.
[0020]
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.
When the right front runner 2 b moves toward the intermediate stopper 4, the subsequent runners 2 connected by the spacer are sequentially drawn out toward the center of the hanger rail 1.
[0021]
Further, 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 at the intermediate stopper 4 side of the left front runner 2a, and a worm mechanism comprising a worm 6 and a worm wheel 7 is built in the gear box 5 as shown in FIG. Yes.
[0022]
One end of the worm 6 protrudes downward from the gear box 5 to form an input shaft 8, and an operating rod 10 is supported by the input shaft 8 through a universal joint 9.
[0023]
A tilt shaft 11 having an axial spline engraved on the outer peripheral surface is fitted into the central portion of the worm wheel 7, and 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 inserted into the runners 2, 2a, 2b.
[0024]
The runners 2, 2a, 2b are movable along the tilt shaft 11, and when the tilt shaft 11 is rotated by known worm mechanisms respectively disposed in the runners 2, 2a, 2b. The slats 3, 3a, 3b are rotated in the same phase.
[0025]
Therefore, when the operating rod 10 is rotated, the slats 3, 3a, 3b are rotated in the same phase.
A first operation code 12 is connected to the left top runner 2a and the right top runner 2b, and a second operation code 13 is connected to the left top runner 2a, and the operation codes 12, 13 are operated. Thus, the head runners 2a and 2b can be moved.
[0026]
The routing of the operation cords 12 and 13 within the hanger rail 1 will be described with reference to FIG. 4. A weight grip 14 is suspended and supported at one end of the first operation cord 12.
[0027]
The first operation cord 12 is guided into the hanger rail 1 through the guide roller 15 at the left end of the hanger rail 1, passes through the left top runner 2a, and is connected to the right top runner 2b.
[0028]
Further, the first operation cord 12 is further guided to the right end of the hanger rail 1 and is reversed by the guide roller 16 so as to pass through the right top runner 2b and the other end is connected to the left top runner 2a.
[0029]
One end of the second operation cord 13 is connected to the left front runner 2a, and is suspended downward through a guide roller 17 at the left end of the hanger rail 1. As shown in FIG. 3, a grip 18 is suspended and supported at the other end through the weight grip 14.
[0030]
Accordingly, when the weight grip 14 is pulled downward, the left front runner 2 a and the right front runner 2 b move toward the intermediate stopper 4. At this time, the grip 18 is pulled upward as the left front runner 2a moves.
[0031]
When the grip 18 is pulled downward, the left front runner 2a and the right front runner 2b move in a direction away from the intermediate stopper 4. At this time, the weight grip 14 is pulled upward.
[0032]
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, 3a, 3b on the left end side of the hanger rail 1, when the weight grip 14 is pulled downward, the leading runners 2a, 2b are in the middle. It moves toward the stopper 4 and the subsequent runners 2 are pulled out sequentially.
[0033]
Then, as shown in FIG. 5, when the leading runners 2a and 2b come into contact with the intermediate stopper 4, further movement of the leading runners 2a and 2b is prevented. At this time, the grip 18 is automatically pulled upward.
[0034]
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 distance between the front slats 3a and 3b is set to be equal to the distance between the other slats 3. Then, the operation rod 10 is suspended between the leading slats 3a and 3b.
[0035]
Further, when the grip 18 is pulled downward, 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.
[0036]
Then, as shown in FIG. 1, the slats 3, 3 a, 3 b are folded at both ends of the hanger rail 1.
In addition, this vertical blind can be pulled out and folded by operating the operating rod 10.
[0037]
That is, by operating the operating rod 10 and moving the left front runner 2a to the intermediate stopper 4 side, the first operation code 12 tries to relax between the front runners 2a and 2b, but the weight grip 14 is lowered. As a result, the slack is absorbed and the right front runner 2 b moves toward the intermediate stopper 4.
[0038]
Therefore, each slat 3, 3a, 3b is pulled out toward the center of the hanger rail 1.
Further, when the operating rod 10 is moved toward the left end side of the hanger rail 1, the subsequent runner 2 is sequentially pushed back by the left front runner 2a, and the right front runner 2b is moved to the right end side of the hanger rail 1, Subsequent runners 2 are sequentially pushed back.
[0039]
Accordingly, each slat 3, 3a, 3b is folded at both ends of the hanger rail 1. At this time, the weight grip 14 is raised and the grip 18 is lowered.
In addition, this vertical blind can be pulled out and folded by operating the leading slats 3a and 3b.
[0040]
That is, when any of the leading slats 3a, 3b is moved toward the center of the hanger rail 1, the slats can be pulled out as in the case of operating the operation rod 10.
[0041]
Further, 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 connected to the right end side of the hanger rail 1. Is moved to the right end side of the hanger rail 1, the slat 3 following the leading slat 3b is folded.
[0042]
At this time, if the left front slat 3 a is moved to the left end side of the hanger rail 1, the subsequent slat 3 is securely folded to the left end side of the hanger rail 1.
When the operation rod 10 is rotated, the tilt shaft 11 is rotated, and the angles of the slats 3, 3a, 3b are adjusted in phase with each other based on the rotation operation of the tilt shaft 11.
[0043]
With the vertical blind constructed as described above, the following operational effects can be obtained.

(4) By operating the head slats 3a and 3b, the operator can perform the operation of pulling out or folding the slats 3, 3a and 3b at the positions of the head slats 3a and 3b.
[0047]
(5) Since only one operating rod 10 is suspended between the head slats 3a and 3b, it is easy to make the distance between the head slats 3a and 3b the same as the distance between the other slats 3. is there. Further, since the interval between the leading slats 3a and 3b can be made the same as the interval between the other slats 3, when the slats 3, 3a and 3b are fully closed, the gap between the leading slats 3a and 3b Occurrence can be prevented.
[0048]
(6) The first operation cord 12 is tensioned by the weight of the weight grip 14, and each slat can be reliably moved when the slats 3, 3a, 3b are fully closed and fully opened.
[0049]
(7) Since the first operation cord 12 is hung on the guide roller 16 acting as a fixed pulley, the operation force acting on the first operation cord 12 acts equally on the leading runners 2a and 2b. To do. Therefore, the moving operation of each slat 3, 3a, 3b can be performed with a slight operating force.
(Second embodiment)
