DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a runner for suspending and supporting a slat of a vertical blind.

[0002]

2. Description of the Related Art As shown in FIGS. 6 and 7, in a vertical blind, a large number of runners 2 are movably supported in a hanger rail 1 fixed to an upper frame of a window or the like. A slat suspension shaft 3 is rotatably supported by each runner 2, and a slat 4 is suspended from the slat suspension shaft 3, respectively.

A slat transfer shaft 5 and a slat rotation shaft 6 are supported in the hanger rail 1 in a parallel and rotatable manner, and the slat transfer shaft 5 and the slat rotation shaft 6 penetrate through the respective runners 2. I have.

The slat transfer shaft 5 has a spiral groove 7 formed on the outer peripheral surface thereof, and the spiral groove 7 is engaged only with the leading runner 2a. Then, when the slat transfer shaft 5 is rotated, the leading runner 2 a is transferred along the hanger rail 1. Each runner 2, 2 a is connected by a spacer 8. Therefore, when the leading runner 2a is moved in the slat pull-out direction, the succeeding runner 2 is sequentially pulled out, and when the leading runner 2a is moved in the slat folding direction, the subsequent runner 2 is sequentially pushed back by the leading runner 2a.

Several splines 9 are engraved on the outer peripheral surface of the slat rotation shaft 6 in the axial direction, and the splines 9 are engaged with the respective runners 2 and 2a. Then, when the slat rotation shaft 6 is rotated, each runner 2,
The slat suspension shaft 3 is rotated via a worm mechanism built in 2a, and the slat 4 is rotated.

An operating device 10 is attached to one end of the hanger rail 1, and an operating cord 11 is provided from the operating device 10.
Is drooping. By operating the operation cord 11, one of the slat transfer shaft 5 and the slat rotation shaft 6 is rotated, so that the transfer operation and the angle adjustment operation of the slat 4 can be performed.

As shown in FIG. 8, the slat 4 is made of a thin plate such as metal or synthetic resin, and a hook provided at a lower end of the slat suspension shaft 3 in a suspension hole 12 formed at an upper end thereof. 13 is inserted and supported by the slat suspension shaft 3.

In the vertical blind constructed as described above, as shown in FIG. 8, when the slats 4 are folded in a fully closed state, that is, in a state of being rotated along the hanger rail 1, as shown in FIG. The upper end corner of the slat 4 interferes with the hook 13 of the runner 2 that suspends and supports the adjacent slat 4.

If the slats 4 are folded in such a state until the adjacent runners 2 come into close contact with each other, the upper end corners of the slats 4 may be bent. Therefore,
As shown in FIG. 10, the height of the upper end corner is reduced so that the upper end corner of the slat 4 does not interfere with the suspension shaft 3 of the runner 2 to prevent the slat 4 from being bent. Has been proposed.

[0010]

However, even if the upper end corners of the slats 4 are formed low as shown in FIG. 10, if the slats 4 are to be folded until the adjacent runners 2 are close to each other, the suspension is still suspended. There is a possibility that the side portion of the hole 12 abuts on the slat suspension shaft 3 to cause bending.

If the width W1 of both sides of the suspension hole 12 is further reduced so as not to interfere with the slat suspension shaft 3 of the adjacent runner 2, the strength is reduced.
The slats may be severed at this point when the is pulled down.

An object of the present invention is to prevent interference between a slat and a runner during a slat folding operation,
An object of the present invention is to provide a runner that can prevent slats from bending.

[0013]

In order to achieve the above object, according to the present invention, a plurality of runners are movably supported in a hanger rail, and slats are respectively provided from slat suspension shafts provided on the runners. Is suspended, the runner is transported in the hanger rail by operation of the operating device, and the slats are transported and the angle is adjusted by rotating the slat suspension shaft. In each of the runners, at the time of folding the slats, a predetermined interval is set between the runners so as to prevent interference between the upper end of each slat and the slat suspension shaft of the runner supporting the adjacent slat. An interval setting unit is provided.

In the second aspect, the interval setting section is provided on the slat suspension shaft so as to set the predetermined interval when the slat is folded in the fully closed state. In the third aspect, the interval setting portion is formed so that the slat suspension shaft is wide along a slat suspended and supported by the slat suspension shaft.

According to a fourth aspect of the present invention, the end portion of the interval setting portion has a flat surface, and the width of the flat surface is smaller than the diameter of the slat suspension shaft.

[0016]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. The runner 21 shown in FIGS. 1 to 3 has the same configuration as the above-described conventional example except for a slat suspension shaft 22.

A hook 23 is formed at the lower end of the slat suspension shaft 22, and the slat 4 similar to the conventional example is suspended and supported on the hook 23. An interval setting portion 24 is formed at an intermediate portion of the slat suspension shaft 22.
The interval setting portion 24 is formed in a cross-sectional shape that is wide only in a direction along the slats 4 suspended and supported by the hooks 23. Further, both end portions of the interval setting portion 24 are formed as flat surfaces having a width smaller than the diameter of the slat suspension shaft 22.

Therefore, as shown in FIG. 4, when the slats are folded in the fully closed state, a predetermined interval W2 is secured between the runners 21, and the upper end corner of each slat 4 is formed by the interval W2. It does not interfere with the slat suspension shaft 22 of the runner 21 that suspends and supports the adjacent slat 4.

As shown in FIG. 5, when the slats 4 are fully opened and folded, the runners 21 are in close contact. In the vertical blind configured as described above, when the slats 4 are fully closed when the slats 4 are folded into one of the hanger rails 1, each runner 2
A predetermined interval W2 is secured by the interval setting unit 24 between the two. Therefore, the slat suspension shaft 2 of the runner 21 for suspending and supporting the slat 4 adjacent to the upper end corner of each slat 4
2 can be prevented, and the upper end corner can be prevented from being bent.

At this time, the interval W2 is secured between the runners 21, so that the convolution size when the slats are convoluted becomes slightly larger. Further, since the slats 4 can have the same configuration as the conventional example, the suspension holes 12
Of the slats 4 can be secured by securing the width of both sides of the slats 4.

When the slats 4 are folded fully open, the runners 21 are folded in close contact with each other, as in the prior art, so that the slats 4 can be folded with a small folded size.

Since both end portions of the interval setting portion 24 are formed of flat surfaces having a width smaller than the diameter of the slat suspension shaft 22, the slats 4 are fully closed and folded, and the interval setting portions 24 of the respective runners 4 are closed. Interval setting section 24 between adjacent runners 21
When the slat 4 is rotated from the state in which the slats 4 are in contact with each other, the friction between the interval setting portions 24 of the runners 21 decreases.

Therefore, the slat rotating operation after the slat 4 is folded in the fully closed state can be easily performed. When the slats 4 are folded in the fully closed state, the flat surfaces of the interval setting portions 24 of the respective runners 21 are in close contact with each other. As a result, the rotation angles of the slat suspension shafts 22 of the respective runners 21 are automatically aligned, and the slats 4 can be reliably completely closed.

[0024]

As described above in detail, the present invention can provide a runner that can prevent the slat from being interfered with the runner during the slat folding operation, thereby preventing the slat from being bent.
