The stopper may be any other known static means, such as one in which a hook is attached to a window frame or the like and the string-like body 22 is hooked onto the hook.

The horizontal blind having the above-mentioned structure can open and close the slats in the following manner. That is, the opening operation section 22a
When pulled, the cord 22 slides the guide member 8 along the guide frame 1.1 towards the upper frame. In this process, the leading member 8 sequentially presses the slat 6 and slides it in this direction, that is, in the slat opening direction. When the leading member 8 has slid to the required position, if the pulling operation of the opening operation part 22a is stopped, the stopper will clamp the string-like body 22 and maintain the slurry 2 in an open state. In order to close the slat 6, the clamping state of the stopper may be released by a predetermined method. Then, the leading member 8 slides in the lower end frame 4 direction by the biasing force of the constant force springs 20, 20, and sequentially slides the slats 6 in the same direction via the ladder cords 7, 7 to bring the slats into the open state. Realize.

In addition, in the closing operation due to the biasing force of the constant force springs 20 and 20 of this embodiment, the portion from the base end of the guide frame l to the curved portion 2 is
This is particularly effective in the horizontal range or in the range where the tilt angle is 30° downward from the horizontal, and when the tilt angle is greater than that, the closing operation can be realized by the weight of the leading member 8 and the slat 6.

Furthermore, the horizontal blind of this embodiment can rotate the slats in the following manner. In other words, rotation port 7 door 1

FIG. 3 is a diagram showing the tilted state of the slat due to the above-mentioned rotational movement. In the state shown in FIG. 3(a), -
The slab 6a located in the range from the upper end frame 5 to the curved part 2 (horizontal range) is in the light-taking state, and the slab 2 toro b located in the range from the curved part 2 to the lower end frame 4 (upright range)
rays of light and is in a state of command. If the slat 6 is rotated clockwise in the figure from this state, it will be in the state shown in FIG. 3(b). That is, in FIG. 2B, the slats 6b located in the horizontal range are in a light ray blocking state, and the slats 6b located in the upright range are in a light ray intake state. Also, the same figure (a)
When the slat 6 is rotated counterclockwise in the figure from the state shown in FIG. 2, the state shown in FIG. That is, in the same figure (C), the slat 6 is in a light beam blocking state over the entire range.

In order to achieve such a movement, a constant tension must be applied over the entire length of the ladder cord 7.7.
In the horizontal blind of this embodiment, the range from the base end of the guide frame l to the curved part 2 is due to the weight of the slat 10, and the range from the curved part 2 to the tip is the slat 6...
The tension is caused by its own weight. Slat 6-
- If you try to apply tension over the entire length due to the weight of the car, not only will the tension not be applied in the range from the base end to the curved part 2, but the slats 6 in the curved part 2 will not work properly. Therefore, in this embodiment, the weight slat 10
This eliminates such problems. J:,
In the above-mentioned slat rotation operation, in this embodiment, the sliding body 1
Since the edge 11a of the slat 1 is formed into a curved surface, rotation is performed smoothly, and since the rotation fulcrum substantially coincides with the central axis of the slat 6, it is possible to rotate the slurry 2 toro without difficulty. can.

Further, since the rotation operation means includes a worm gear mechanism, the rotation position of the slat 6 can be accurately maintained. The above-mentioned slat rotation operation is performed by the weight slat 10.
This is realized on the condition that the curve exists within the curved portion 2.

Further, a constant force spring 20 is used for the above-mentioned slat rotation operation.
The rotational movement of this embodiment using the weight slat 1O, in which the urging force of 20 has no influence, is such that the portion from the base end of the guide frame 1 to the curved portion 2 is horizontal or 30° below the horizontal. This is particularly effective in a range where the slat 6 is inclined, and when the angle of inclination is greater than that, tension can be applied to the area due to the weight of the slat 6.

In addition, the horizontal blind of this embodiment uses the guide frame l as a guide structure for the slats 6, etc., and as a result, no unnecessary force is applied to the house compared to the wire support structure commonly used in the past. In addition, it is possible to increase the size, the installation work is easy, and the string-like body 22 and the like can be stored in the bracket guide frame 1, thereby maintaining an aesthetic appearance.

It should be noted that the present invention is not limited to the embodiments described above, and it goes without saying that various modifications can be made without departing from the gist of the invention. For example, a plurality of weight slats 10 may be provided.

[Effects of the Invention] As is clear from the above description, according to the present invention, tension is applied to the ladder cord located in the horizontal range of the guide frame by the weight slat, and the ladder cord has a curved part such as a sunroom window. It is possible to provide a horizontal blind which can be attached to a window and whose slats can be rotated to finely adjust the amount of incident light.
