BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a blind.

[0002]

2. Description of the Related Art As a conventional blind, an actual Kaihei 1-1
There is one disclosed in Japanese Patent No. 50896. The blind shown in this figure uses slats in which a frill portion such as a lace knitted material made of a material having low self-shape retention is integrally formed on the side edge of a strip-shaped slat body made of a material having high self-shape retention. . A plurality of slats are arranged at a predetermined interval in the vertical direction, and the slats are placed on the ladder cord one by one. An insertion hole is provided in the slat main body of each slat, and the lifting cord is passed therethrough.

[0003]

However, in the conventional blind as described above, when the slats are placed on the ladder cord, the horizontal cord of the ladder cord must penetrate the lace knitted fabric portion, and The blind assembling work was very troublesome because of making cuts in the knitted fabric. Further, when a cut is made in the lace knitted fabric, the lace knitted fabric is divided at that portion, so that the lace knitted fabric is turned over or bent, and the continuity of the lace knitted fabric is lost, which causes a problem in appearance. An object of the present invention is to solve such a problem.

SUMMARY OF THE INVENTION According to the present invention, the first flat plate portion of the cloth slat having a chevron cross section and having a self-shape-retaining property, which is composed of a first flat plate portion and a second flat plate portion, is made of a coarse cloth. The above problem is solved by forming the flat plate portion with a fine mesh. That is, the blind according to the present invention includes a head box, a number of slats that are supported in an aligned state by a ladder cord, a bottom rail that is disposed at one end of a slat row, and one end that is connected to the bottom rail and that is formed on the slats. The other end of the slat is passed through the lifting cord insertion hole, and the other end of the lifting cord is inserted in and out of the headbox.
While doing, rotate the slats with the ladder code
It is a blind to perform , and the slat has a chevron-shaped cross section composed of a first flat plate portion and a second flat plate portion that form a predetermined angle with each other. When the size is set slightly larger than the size, the first flat plate portion is formed of a transparent light-transmitting cloth having self-shape retention, and the second flat plate portion is fine mesh having self-shape retention. It is made of light-shielding cloth ,
When the first flat plate portion is positioned on the indoor side and the second flat plate portion is positioned on the window side,
In both cases, the lifting cord insertion hole is from the peak of the chevron to the second flat plate.
It is a long hole that extends toward the side edge of the part, and it moves up and down
The position where the cord is introduced into the headbox
It is characterized in that it is arranged so as to be biased toward the window side from the center line of the bottom of the box . The slat may be configured by forming the first flat plate portion and the second flat plate portion with an integral woven material or knitted material, and curing these with a thermoplastic resin. The first flat plate portion may be a lace knitted fabric.

In the blind according to the present invention, when the slat has a mountain-shaped cross section, when the slat is rotated when the slat is fully closed, one flat plate portion becomes vertical and the other flat plate portion protrudes indoors or outdoors. So the first
The window is covered by either the flat plate portion or the second flat plate portion. For this reason, the first flat plate portion is formed of a material that can illuminate, such as a coarse lace knitted fabric, and is positioned inside the room.
By slashing the slats,
The second flat plate part is hidden behind the first flat plate part when rotating.
The first flat plate parts of the upper and lower slats overlap each other,
The window is covered by the first flat plate,
India covered windows with lace curtains
Performs the same function as. On the other hand, self-shape retaining the second flat plate portion
By forming in a fine light-shielding cloth having a lifting property, bets rotational state of the slats second flat portion becomes vertical

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an overall view of the blind of the present invention, and FIG.
1 shows a side view of FIG. A plurality of slats 10 are arranged at predetermined intervals in the vertical direction. A head box 12 is arranged at the upper end of the ten rows of slats, and a bottom rail 14 is arranged at the lower end. A ladder cord 16 is provided between the head box 12 and the bottom rail 14 to support each slat 10.
Elevating cord 1 with one end attached to bottom rail 14
The other end 8 is fixed to a winding pipe 22 in the head box 12 through a lifting cord insertion hole 20 provided in the slat 10. The lifting cord 18 is the winding pipe 2
2 can be wound and unwound, and a lifting cord 1
The slat 10 opens and closes by winding and unwinding 8. The rotation of the take-up pipe 22 is
This is performed by the operation code 24 provided at the end. One end of the ladder cord 16 is also connected to the winding pipe 22. However, the ladder code 16 is not wound up more than a predetermined amount.

FIG. 3 is a perspective view of the slat 10. The slat 10 has a mountain-shaped cross-section formed by a first flat plate portion 26 and a second flat plate portion 28 that form a predetermined angle with each other, and the first flat plate portion 26 and the second flat plate portion 28 are formed of an integral woven material or knitted material. And cured with a thermoplastic resin. The first flat plate portion 26 is formed of a loose cloth such as a lace knitted fabric, which is a material that can illuminate, and the second flat plate portion 28 is formed of a fine cloth having a high light shielding property. An elevating cord insertion hole 20 that is a long hole extending from the apex of the chevron toward the side edge of the second flat plate portion 28 is formed. The lifting cord insertion hole 20 is not formed in the first flat plate portion 26 except for the apex portion of the mountain shape. The first flat plate portion 26 is located on the indoor side, and the second flat plate portion 28 is located on the window side. Correspondingly, shown in FIG.
As described above, the lifting cord 18 is placed in the head box 12.

It is placed so that it is biased toward the interior.

FIG. 4 shows a side view of the blind when the slat is rotated to the indoor side when it is fully closed. Ladder code 16 on the window side
The slats 10 are slanted and the first flat plate portion 26
Becomes almost vertical, and the second flat plate portion 28 projects toward the window side. As a result, the window is covered with the lace knitted fabric of the first flat plate portion 26, and is in a semi-transmissive state. The elevating cord insertion hole 20 is also formed at the apex of the chevron, but the vertically adjacent slat 10 has the chevron shape of the lower portion of the first flat plate portion 26 of the upper slat 10 and the first flat plate portion 26 of the lower slat 10. Since the apex portion slightly overlaps, the elevating cord insertion hole 20 at the apex of the chevron is covered by the first flat plate portion 26 of the adjacent upper slat 10. As a result, the outdoor light does not directly enter all the portions of the lifting cord insertion hole 20. On the other hand, in the direction opposite to the semi-transmissive state of light, that is, in the fully closed state in which the winding pipe 22 is rotated clockwise, the second flat plate portion 28 is substantially vertical, and
The flat plate portion 26 projects toward the indoor side. As a result, the window is entirely covered with the second flat plate portion 28, so that the window is shielded.

[0009]

As described above, according to the present invention, when the slat is rotated at the time of fully closing by making the shape of the slat a mountain-shaped cross section, when one flat plate portion is in a vertical state, the other flat plate portion is in a vertical state. Is projected indoors or outdoors, the window is covered by either the first flat plate portion or the second flat plate portion. Therefore, the indoor-side to form a first flat plate portion with lighting capable material such as a coarse knitted lace fabric
