2. Description of the Related Art In a horizontal blind, a slat, usually formed of a thin aluminum plate, is suspended from a head box via a ladder cord and an elevating cord so as to be adjustable in angle and to be able to ascend and descend.

In such a horizontal blind, since the slat gives an inorganic impression, a horizontal blind as shown in FIG. 6 has been proposed. That is, a plurality of slats 2 are suspended from the head box 1 so as to be able to move up and down and to be adjustable in angle, and each slat 2 is formed to be able to bend and extend at the center in the width direction.

The upper ends of the slats 2 on both sides in the longitudinal direction are supported at equal intervals by a pitch cord 3 fixed to the head box 1 at the upper end. The bending portion of each slat 2 is supported at equal intervals by an angle adjustment cord 4 suspended from the head box 1, and the upper end of the angle adjustment cord 4 is rotatably supported in the head box 1. Supported by the angle adjustment shaft.

An elevating cord 5 is inserted in the vicinity of the pitch cord 3 attachment portion of each slat 2, and one end of the elevating cord 5 is connected to the lowermost slat 2, and the other end passes through the inside of the head box 1. Headed to one side, head box 1
The headbox 1 is suspended from one side via a self-weight drop prevention device disposed therein.

Then, the head box 1 is installed on a window frame or the like with the angle adjustment cord 4 side as the indoor side. In such a horizontal blind, since each slat 2 is formed so as to be able to bend and stretch at its center in the width direction, and its own weight does not easily sag,
The degree of freedom of the material is wide, and the slat 2 having a texture according to the material can be configured.

By rotating the angle adjusting shaft to raise and lower the angle adjusting cord 4, the bending / extending portion of each slat 2 is raised and lowered, and as shown in FIGS. Is done.

As shown in FIG. 6, when the upper half of each slat 2 is supported in the horizontal direction, a gap for obtaining a field of view between each slat 2 is secured, and the amount of light collected is adjusted while taking in direct light. be able to.

As shown in FIG. 7, when the bending portion is lifted so that the height of the upper edge of each slat 2 coincides with the height of the lower edge of the upper slat 2, the function as a blindfold can be obtained. Lighting and ventilation can be provided.

[0010] As shown in FIG. 8, by lowering the bending portion of each slat 2 and suspending each slat 2 by the pitch cord 3, the upper edge of each slat 2 and the upper tier of the upper slat 2 are provided. The lower edges of the slats 2 overlap and each slat 2 is in a fully closed state.

When the lowermost slats 2 are pulled up by the lifting cord 5, as shown in FIG. 9, the slats 2 are sequentially pulled up from the lower slats 2 and become fully open.

[0012]

In the horizontal blind as described above, direct light enters in any case in the non-fully closed state of the slat 2 shown in FIGS. Therefore,
When the slat 2 is not fully closed, there is a problem that the amount of light cannot be adjusted while blocking direct light.

In the fully closed state of the slats 2 shown in FIG. 8, although the direct light can be substantially blocked, the overlapping portions of the slats 2 connected vertically are exposed upward on the outdoor side. Therefore, there is a problem in that light such as a sunbeams enters the room from the overlapping portion.

As shown by the solid line in FIG. 10, when the bending portion is pulled up by the angle adjusting cord 4 from the state where the upper half of each slat 2 is supported obliquely, the lifting cord 5 is tensioned. Therefore, as shown by a chain line in the figure, the upper half of each slat 2 is rotated upward with the vertically moving lifting / lowering cord 5 as a rotation fulcrum.

Then, when the angle is adjusted so that the upper half of each slat 2 is horizontal, each slat 2 is in a state of protruding indoors. The angle adjustment cord 4 exposed on the indoor side also moves up and down.

Accordingly, there is a problem that the operation of each slat 2 during the angle adjusting operation becomes visually unstable, which is not aesthetically pleasing. SUMMARY OF THE INVENTION An object of the present invention is to provide a horizontal blind in which a slat is bent and stretched in the width direction to adjust an angle, and when the slat is not fully closed, the amount of light collected can be adjusted while blocking the incidence of direct light. It is an object of the present invention to provide a horizontal blind capable of performing a slat angle adjustment operation smoothly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below. The horizontal blind shown in FIG. 1 has a plurality of slats 12 suspended from a head box 11 so that the slats 12 can be moved up and down and the angle can be adjusted.

Each of the slats 12 has a bag-shaped cover made of cloth or the like divided into two in the width direction by sewing or the like, and a core material is inserted into each bag-shaped portion. Therefore, each slat 12
The upper half and the lower half are connected at the center in the width direction so as to be able to bend and stretch.

Pitch tapes 13 are hung from the front surfaces of both ends of the head box 11, and the upper half portions of the slats 12 are supported on the pitch tapes 13 at equal intervals. The upper half of each slat 12 is sewn to the pitch tape 13 at the upper and lower edges of its cover.

On the lower edge of the lower half of the lowermost slat 12,
The upper edge of the hanging curtain 14 is sewn, the hanging curtain 14 is formed in a bag shape, and the weight 14a is accommodated therein. An angle adjusting tape 15 is hung down from both sides of the head box 11, and the slats 1 are attached to the angle adjusting tape 15.
The lower edges of the lower half 2 are sewn at equal intervals. The upper end of the angle adjusting tape 15 is supported by an angle adjusting shaft (not shown) rotatably supported in the head box 11.

A tilt operation code 16 is hung on one side of the head box 11, and the tilt operation code 16

Is raised and lowered.

As shown in FIG. 2, in each of the slats 12, an insertion ring is attached near the sewn portion of the angle adjusting tape 15, and a lifting cord 17 is inserted through the insertion ring. One end of the lifting cord 17 is connected to the lower edge of the lower half of the lowermost slat 12, and the other end is guided into the head box 11, and is suspended from one side of the head box 11 through a weight drop prevention device, Operation code 1
8 are connected.

Therefore, the operation of the operation code 18 allows the lowermost slat 12 to be raised or lowered. On the front face of the head box 11,
A blindfold 19 made of the same material as the cover of each slat 12 is attached, and the lower edge of the blindfold 19 is
The uppermost slat 12 is connected to the upper edge of the upper half.

Then, the head box 11 is attached to a window frame or the like so that the pitch tape 13 is on the indoor side. Therefore, the head box 11 is shielded from the view from the indoor side by the blinds 19 and
The incidence of external light from the gap between the slat 12 and the uppermost slat 12 is blocked.

Next, the operation of the horizontal blind configured as described above will be described. By operating the tilt operation code 16 and raising and lowering the angle adjusting tape 15, FIGS.
As shown in FIG. 4, the angle is adjusted by rotating the lower half of each slat 12 while being suspended from the upper half. At this time, the lower half of each slat 12 is turned toward the outdoor side.

As shown in FIG. 4, when the angle adjusting tape 15 is lowered so that the lower half of each slat 12 is suspended from the upper half, the lower edge of the lower half of each slat 12 The upper edge of the upper half of the lower slat 12 is overlapped with each other, and each slat 12 is fully closed.

In this state, the incidence of direct light into the room is reliably blocked, and the overlapping portions of the slats 12 are exposed downward at the outside of the room, so that light such as a sunbeam through the room is exposed to the room. There is no incidence. Therefore, external light can be completely blocked.

As shown in FIG. 3, the lower half of each slat 12 is supported obliquely downward from the upper half, and the upper edge of the upper half of each slat 12 and the lower half of the upper slat 12 are provided. When the angle adjusting tape 15 is pulled up so that the lower edge of the slats is substantially at the same height, the incidence of direct light into the room is cut off, and the upper surface of the lower half of each slat 12 and the upper slat The indirect light enters the room by reflecting off the lower surface of the lower half portion 12.

Therefore, during the period from the state shown in FIG. 3 to the state shown in FIG. 4, it is possible to adjust the amount of light collected by indirect light while blocking the incidence of direct light into the room. At this time, as the lower edge of the lower half of the lowermost slat 12 rises,
The lifting cord 17 becomes slack.

As shown in FIG. 2, when the angle adjusting tape 15 is pulled up so that the lower half of each slat 12 is supported in the horizontal direction, the lifting cord 17 is further slackened. In this state, visibility can be secured from the gap between the upper edge of the upper half of each slat 12 and the lower half of the upper slat 12, and direct light enters through the gap.

By operating the operation code 18, the lifting code 1
When the slats 12 are pulled up, the lower edges of the lowermost slats 12 are pulled up, and the slats 12 are sequentially pulled up from the lower slats 12 in a state where the upper half and the lower half of the slats 12 are turned upside down. And when each slat 12 is pulled up to the upper limit, it will be in the fully open state shown in FIG.

With the horizontal blind as described above, the following operational effects can be obtained. (1) By raising and lowering the angle adjusting tape 15, the angle of the lower half of each slat 12 can be adjusted, and the amount of light collected can be adjusted. (2) As shown in FIG. 4, when each slat 12 is fully closed, it is possible to block direct light from entering the room and to prevent light from leaking from the overlapping portion of the slats 12 into the room. Can be prevented. (3) In the range from the fully closed state shown in FIG. 4 to the state shown in FIG. 3 by pulling up the angle adjusting tape 15, the amount of collected light can be adjusted while blocking the incidence of direct light. (4) When the angle of each slat 12 is adjusted, the pitch tape 13 supporting the upper half of each slat 12 does not move up and down, and the lifting cord 18 is in a slack state. Each slat 12 does not move back and forth with the operation. Therefore, the angle adjustment operation of the slats 12 can be performed smoothly, and the operation can be stabilized to improve the aesthetic appearance. (5) By adjusting the height of the hanging curtain 14, the height of the horizontal blind can be adjusted. (6) By the weight 14a supported by the hanging curtain 14, when the slats 12 are fully closed, the lower half of each slat 12 is urged downward, so that the overlapping portion of each slat 12 can be brought into closer contact. (7) If the pitch tape 13, the angle adjusting tape 15 and the lifting cord 17 are removed from the head box 11, and the core material is taken out from the cover of each slat 12, each cover and the pitch tape 13, the angle adjusting tape 15 and the lifting cord 1 are removed.
