DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a venetian blind.
・ This is related to the roll screen.

[0002]

2. Description of the Related Art A roll screen is constructed by attaching an upper edge of a curtain material to a peripheral surface of a rotating cylinder.

[0003]

A light-shielding sheet may be used for the curtain of a roll screen for the purpose of shading, but the opposite side can be seen through the curtain of a normal roll screen for the purpose of interior decoration. If a sheet with sufficient lighting is used, and if you want to avoid sunlight coming into the window with a normal roll screen that has lighting, install another light-blocking curtain on top of the roll screen. There must be. However, a special bracket is required to attach the roll screen and the general side-opening curtain doubly, and since the rotating cylinder and the curtain rail are different in form, installing them in duplicate will result in poor appearance and impair the aesthetics of the room. Since the roll screen and the horizontal opening curtain have different vertical and horizontal opening / closing directions, the opening / closing operation is confusing and difficult to handle. Therefore, the present invention focuses on the fact that the roll screen and the Venetian blind are both opened and closed vertically, the roll screen is characterized by daylighting, and the Venetian blind is characterized by the light-shielding property. It is an object of the present invention to provide a Venetian blind roll screen having both a function of daylighting and a function of shading as well as a change in design.

[0004]

According to the present invention, there is provided a Venesian.
The blind roll screen 20 has a large number of lateral folds (13) projecting from one side of a curtain surface 12 of a roll screen which is hung down by joining an upper edge to a peripheral surface of the rotating cylinder 11 at a required interval vertically. At least two of the left and right ends of the lateral folds (13) are vertically connected by ladder cords 14A and 14B, and the upper end of the ladder cord 14 is joined to the rotary cylinder 11 .

The portion of the uppermost horizontal fold 13A between the curtain fabric 12 and the ladder cord 14 is formed when the joining points 15 and 17 between the horizontal fold 13A and the curtain fabric 12 and the ladder cord 14 are aligned horizontally. It is hardened so as not to bend up and down between the joining points 15 and 17 and to be horizontally supported like a cantilever. For this purpose, a hard plate such as a slat of a Venetian blind is preferably inserted into the uppermost horizontal fold 13A as a core material.

The joint points 16 and 18 between the rotating cylinder 11 and the curtain material 12 and the ladder cord 14 are as follows .
(1) to (3) show Venetian blind rolls
Is set so that the cycle 20 changes. (1) Rewinding the curtain material 12 to make the uppermost horizontal fold 1
3A is the junction 15 of the curtain material 12 and the ladder cord 14
When the horizontal support is provided between the ladder cord 14 and the upper part 27 of the ladder cord 14, the upper part 27 from the junction 15 with the uppermost fold 13A of the curtain fabric 12 to the junction 16 with the rotary cylinder 11 is supported. The upper portion 26 from the joint 17 with the horizontal fold 13A to the joint 18 with the rotary cylinder 11 is
It is divided into left and right with the rotating cylinder 11 and the uppermost horizontal fold 13A interposed therebetween, and is surrounded by the upper part 27 of the curtain material 12, the upper part 26 of the ladder cord 14, the rotary cylinder 11, and the uppermost horizontal fold 13A. space 28 is Ru can. (2) When the curtain fabric 12 is wound outside, the upper portion 26 of the ladder cord 14 is loosened and the uppermost fold 13A is loosened when the upper fold 13A is unwound when the upper fold 13A appears. Appears from the ground 12, so that the junction 18 of the ladder cord is the junction 1 of the curtain.
Current is earlier than 6 (FIGS. 1 and 7). Further, when the rotating cylinder 11 continues to rotate in the direction of rewinding the curtain fabric 12, the joint 18 between the ladder cord 14 and the rotating cylinder and the joint 17 between the uppermost horizontal fold are wound up, and the curtain fabric 12 is rolled up. Points 15 and 1 of the ladder cord 14
7 is aligned at the same height, the uppermost horizontal fold 13A is horizontal between those junctions 15 and 17 (FIGS. 2 and 7). (3) When the ladder cord 14 is wound outside, the upper part 27 of the curtain fabric 12 is loosened at the time when the ladder cord 14 is rewound and the uppermost horizontal fold 13A appears, and the uppermost horizontal fold 13A is laddered. Ru appeared hanging from the code 14. Thus, the junction 16 of the curtain fabric is Ru appear earlier than the junction 18 of the ladder cord (Figure 4). In addition, rotating cylinder 1
1 is continuously rotated in the direction in which the ladder cord 14 is rewound, the joining point 1 of the curtain material 12 with the rotating cylinder is
6 and the junction 15 of the uppermost fold are wound up, so that the junctions 15 and 17 of the curtain material 12 and the ladder cord 14 are aligned at the same height. Yokohida 13A is horizontal (Figure 5).

For this purpose, in general, regardless of which of the curtain fabric 12 and the ladder cord 14 is wound outside, they are unwound and joined to the junctions 15 and 1 with the uppermost horizontal fold 13A.
7 are at the same height, their uppermost folds 1
The junctions 16 and 18 between the curtain material 12 and the ladder cord 14 and the rotary cylinder 11 so that the upper portions 26 and 27 from 3A are bilaterally symmetrical with the rotary cylinder 11 and the uppermost horizontal fold 13A interposed therebetween. (FIGS. 2 and 5), and FIG. 7 illustrates an embodiment that is an exception in that case.

[0008] The Venetian bra thus constructed
In the Indian roll screen 20, (1) the curtain fabric 12 takes the form of an original roll screen that is wound up by the rotating cylinder 11 and moves up and down. (2) On the other hand,
A number of horizontal folds (1
3) indicates that one of the front and back side edges is a ladder code 14;
And the other side is gripped by the curtain fabric 12 and connected vertically, so that the upper and lower sides of the upper and lower slats are connected by ladder cords 14 and 40 to the ladder code 40 on one side of the suspended Venetian blind. (3) Therefore, the roll screen and the Venetian blind are combined through the curtain material 12 to form a double structure.
Therefore, the Venetian blind rolls according to the present invention
The lean 20 can also be formed by joining the ladder cord 40 on one side of the Venetian blind to the curtain fabric 12, and the horizontal folds (13) use the slats 13 of the Venetian blind or the hard substrate 23 similar to the slat to the curtain fabric 12. 1
2 and can be formed between the folds (13) of the curtain material 12 formed by folding.
3 or the slat substrate 23 may be interposed. FIG. 8 illustrates a case where the curtain fabric 12 is also used as the ladder cord 40 on one side of the Venetian blind, and each slat 13 is configured by covering the front and back of the slat substrate 23 with the decorative sheet 22, and the one side edge 19 is formed. The other side edge 21 is sewn to the curtain fabric 12 and joined to the ladder cord 14. FIG. 9 illustrates a case where the ladder cord 40 is joined to and integrated with the curtain fabric 12, and between the front and back ladder cords 14 and 40, which are knitted in a double-sided tape form by a small-width knitting machine or a loom, One of the tape-shaped ladder cords 40 is sewn to the curtain fabric 12 and connected to the curtain ladder cords 14 and 4.
The slat 13 is inserted into the loop of the connecting thread 24 connecting the 0s.

The rotating cylinder 16 is supported on a window frame or the like by being supported by a bracket like a conventional roll screen, and is driven to rotate by a built-in spring or a wheel mounted on an end. 1 to 7, the arrows drawn around the rotary cylinder 16 indicate the direction in which the curtain fabric 12 is rewound. As described above, the rotation direction of the rotary cylinder 16 is the same as the direction in which the curtain fabric 12 is wound outside. (FIGS. 1, 2, 3, and 7), or the direction in which the ladder cord 14 is wound outward (FIGS. 4 to 6).

When unwinding the curtain material 12 wound around the rotary cylinder 11, (a) the upper portion 26 of the ladder cord 14 is slackened and the uppermost horizontal fold 13 A hangs down from the curtain material 12 and appears. In the case where the horizontal folds 13 are made of light-shielding slats, the entire surface of the curtain fabric 12 is covered with the slats 13 and the sunlight is blocked on both sides (FIGS. 1 and 7). (B) Further, the rotating cylinder 11 is rewound. If it continues to rotate in the direction, the junctions 18 and 17 of the ladder cord 14 are wound up, the junctions 15 and 17 of the curtain fabric 12 and the ladder cord 14 are aligned at the same height, and the horizontal fold 13 is horizontal, A gap 25 is formed between the folds 13 and 13 so that the sunlight penetrates the front and back of the curtain fabric 12 (FIGS. 2 and 7). (C) If the rotating cylinder 11 continues to rotate in the rewinding direction, Junction 18 and 17 of the ladder cord 14 is the curtain fabric 12 which is wound more higher by the junction 15 drops between the lateral folds 13 are further unwound, Yokohida 13
Will hang down from the ladder cord 14, and the entire surface of the curtain fabric 12 will be again covered with the horizontal folds 13. If the slats are made of light-shielding slats, the sunlight will be blocked again on the front and back of the curtain fabric 12 ( (Fig. 3).

In the initial state in which the horizontal fold 13 hangs down from the curtain material 12 and the final state in which the horizontal fold 13 hangs down from the ladder cord 14, the front and back of the horizontal fold 13 are inverted. Since the shadow of the surface of the fold 13 appears on the surface of the curtain material 12, the roll screen 2
The design of No. 0 is the case where the shadow of the surface of the horizontal fold 13 appears, the case where the horizontal fold 13 is horizontal and the shadow does not appear and only the shadow of the curtain fabric 12 appears, or the case where the horizontal fold 13 is inverted and In the case where the horizontal folds 13 are formed of light-shielding slats, there is a change in the sunlight on the front and back of the curtain ground, and the distance between the upper and lower slats 13 If the width is shorter than the width, the interior of the room can be made dark by the roll screen 20. Such a roll screen 20
4 also occurs when the curtain material 12 wound inward on the rotating cylinder 11 is unwound (FIG. 4).
~ 6). When the lateral fold 13 is formed of a hard thin plate (13) which is easily bent like a slat of a Venetian blind, in order to make it hard to bend and bend, as shown in FIG. 8, one side edge 19 of the slat 13 is used. The whole may be joined to the curtain material 12.

[0012]

(1) As described above, according to the present invention, a Venetian blind roll screen 20 having both a light-shielding property and a light- receiving property is obtained by a combination of a slat 13 having a light-shielding property and a curtain material 12 having a light- receiving property. Can be (2) The slat 13 and the curtain fabric 12 is turned inextricably linked, wound up on the same rotating cylinder (11), the slats 13 and the curtain fabric 12 will not be separated during use, according to the present invention Venetian blind
-The roll screen 20 can be handled like a conventional roll screen. (3) The shadow of the horizontal fold 13 is reflected on the surface of the curtain material 12, and the shadow changes according to a slight change in the rotation angle of the rotary cylinder 11. Therefore, in the process of turning the horizontal fold 13 upside down, the Venetian blind is used. The appearance of the roll screen 20 is as follows: (a) a case where a shadow on the surface of the horizontal fold 13 appears;
There are three patterns: a case where the shadow of the curtain fold 12 is emphasized with almost no shadow of the horizontal fold 13 and only a shadow of the back surface of the horizontal fold 13 appearing. A beautiful aesthetic. (4) Even if the horizontal fold 13 is formed of a hard thin plate (13) that is easily bent like a slat of a Venetian blind, one side edge is protected by the closely attached curtain fabric 12, so that the hard thin plate hits a foreign substance. There is no danger of (13) being bent. (5) The slat 1 is between the left and right ear ends of the curtain base 12.
3, the curtain material 12 is not easily swung to the left and right when it is wound on the rotating cylinder 11, and the left and right ear ends are aligned neatly to move the curtain material 12 to the rotating cylinder 11.
Can be rolled up.
