It is transmitted to the angle adjusting shaft 4.

Elevating cords 15a to 15c are inserted in the vicinity of the supporting position of the ladder cord 2 of the slat 3,
One ends of the lifting cords 15a to 15c are connected to the bottom rail.

The other ends of the lifting cords 15a to 15c are
As shown in FIGS. 4 and 6, the head box 1 is guided through guide rollers, respectively, and is guided to the outside of the head box 1 from a lead-out hole 16 formed in the longitudinal center of the head box 1. Next, it is hung downward through the self-weight drop prevention device 17 in the operation unit 8.

The self-weight drop prevention device 17 is composed of a gear-shaped fixed roller 18 and a gear-shaped movable roller 19 provided for each of the lifting cords 15a to 15c.

The fixed rollers 18 are rotatably supported by the case of the operation unit 8, and the fixed rollers 18 are
The movable roller 19 located in front of the operation unit 8 is
It is movably and rotatably supported along the elongated hole 20 formed in. That is, the movable roller 19 is
Due to the long hole 20, the fixed roller 18 moves as it moves upward.
It is supported so that it can move in an oblique direction.

Therefore, in the self weight drop prevention device 17,
When the lifting cords 15a to 15c are pulled out downward from the operation unit 8, the slat 3 is pulled up, and the movable roller 19 moves to the lowest limit along the long hole 20 as shown by a chain line in FIG.

From this state, the lifting cords 15a-1
If the lifting cords 15a to 15c are pulled into the head box 1 from the operation unit 8 based on the weight of the slats 3 while pulling 5c straight down so that the lifting cords 15a to 15c do not contact the movable roller 19, the slats 3 Goes down.

If the elevating cords 15a to 15c are pulled obliquely forward and the elevating cords 15a to 15c are pulled into the head box 1 while being in contact with the movable roller 19, the elevating cords 15a to 15c can be moved along with the movement. The roller 19 moves upward and its movable roller 19
Elevating cords 15a to 15c between the roller and the fixed roller 18
Are clamped and fixed. Therefore, in this state, the slat 3 is prevented from falling by its own weight.

Next, the operation of the horizontal blind constructed as above and the operation unit 8 thereof will be described. As shown in FIGS. 2 and 4, the operating unit 8 is moved to the right end side of the head box 1 to move the drive spur gear 10 to the driven spur gear 5.
When engaged with a, the operating rod 14 hangs down to the right end side of the head box 1 and, as shown in FIG. 7, the lifting cords 15a to 15c are guided from the lead-out hole 16 to the operating unit 8 on the right end side of the head box 1. And is hung from the operation unit 8.

When the operating rod 14 is rotated in this state, the angle adjusting shaft 4 is rotated and the slat 3 is adjusted in angle. When the lifting cords 15a to 15c are pulled out from the operation unit 8, the slat 3 is pulled up, and when the lifting cords 15a to 15c are pulled into the head box 1, the slats 3 are lowered and the self-weight descent prevention device 17 is activated. Then, the slat 3 is suspended and supported at a desired position.

Therefore, in this state, the operating rod 14 and the lifting cord 1 suspended from the right end of the head box 1 are supported.

As shown in FIG. 8, each of the lifting cords 15a to 15c has a lead-out hole 16
Is guided to the operation unit 8 on the left end side of the head box 1 and hangs down from the operation unit 8.

When the operating rod 14 is rotated in this state, the angle adjusting shaft 4 is rotated and the slat 3 is adjusted in angle. When the lifting cords 15a to 15c are pulled out from the operation unit 8, the slat 3 is pulled up, and when the lifting cords 15a to 15c are pulled into the head box 1, the slats 3 are lowered and the self-weight descent prevention device 17 is activated. Then, the slat 3 is suspended and supported at a desired position.

Therefore, in this state, the horizontal blind can be used for left operation. With the horizontal blind configured as described above, the following operational effects can be obtained. (1) By moving the operation unit 8 along the head box 1, the operation unit 8 can be used as either a horizontal blind for left operation or right operation. (2) The operation unit 8 is used to switch between left operation and right operation.
Drive along the head box 1 to drive the spur gear 1
Since it is only necessary to engage 0 with one of the driven spur gears 5a and 5b, the conversion work can be easily performed, and it is not necessary to remove the head box 1 from the mounting surface. (3) Since the rotating shafts of the fixed roller 18 and the movable roller 19 are set in the direction along the moving direction of the operation unit 8, the lifting cords 15a to 1 for both rollers 18 and 19 are used.
5c is guided from either the right or left side,
The movable roller 19 can be operated similarly to the fixed roller 18.

The above-described embodiment can also be configured as follows. The operation unit 8 may accommodate only the angle adjusting function of the operation rod 14, the input shaft 13, the gear shaft 9, etc., and only the angle adjusting operation can be converted to the left and right. The drive spur gear 10 may be rotationally driven by an operation code or an operation dial instead of the operation rod 14. -The raising / lowering cord 15a from the lead-out hole 16 to the operation unit 8
15c may be guided, and the operation unit 8 may accommodate only the self-weight lowering prevention device 7 so that only the slat elevating operation can be switched to the left and right. -The left-right conversion function may be applied to a lifting device such as a pleated curtain or a Roman shade.
