Detailed Description of the Invention

[0001]

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

Although a light-shielding sheet may be used for the curtain material of the roll screen for the purpose of shading, the opposite side can be seen through to the curtain material of the ordinary roll screen for the purpose of interior decoration. If a sheet with a certain level of daylighting is used, and if you want to avoid the sun shining into the window with such a normal daylighting roll screen installed, install another shade curtain over the roll screen. There must be. However, a double bracket is required to double-install the roll screen and the general horizontal curtain, and since the rotating cylinder and the curtain rail have different configurations, double-installation causes poor appearance and spoils the aesthetics of the room. Since the roll screen and the lateral 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 properties, and the Venetian blind is characterized by light shielding properties. It is an object of the present invention to provide a double roll screen having two functions of a light-collecting property and a light-shielding property as well as a change in the design.

[0004]

A double roll screen 20 according to the present invention is a roll screen curtain 12 which is hung down by joining an upper edge to a peripheral surface of a rotary cylinder 11 and is vertically hung from one side of the curtain cloth 12 by a predetermined distance. A large number of lateral folds (13) are projected at a distance, and at least two positions on the left and right of the tip of the large number of lateral folds (13) are ladder cords 14A
The ladder cord 14 is connected vertically by 14B.
The upper end of is joined to the rotary cylinder 11.

The portion of the uppermost lateral fold 13A between the curtain material 12 and the ladder cord 14 is such that when the joint points 15 and 17 of the lateral fold 13A and the curtain material 12 and the ladder cord 14 are aligned horizontally. Between the joint points 15 and 17, it does not bend vertically and is hardened so that it can be horizontally supported like a double-supported beam. For that purpose, a hard plate such as a Venetian blind slat is preferably inserted as a core material in the uppermost lateral fold 13A.

The joint points 16 and 18 of the rotary cylinder 11, curtain 12 and ladder cord 14 are (a)
When the curtain material 12 is unwound and the uppermost lateral folds 13A are supported horizontally between the junction points 15 and 17 of the curtain material 12 and the ladder cord 14, the uppermost lateral folds of the curtain material 12 are The upper portion 27 from the joint point 15 to the joint point 16 with the rotary cylinder 11 and the upper portion 26 from the joint point 17 with the uppermost fold 13A of the ladder cord 14 to the joint point 18 with the rotary cylinder 11 are formed. , The rotary cylinder 11 and the uppermost fold 13A are sandwiched between the upper and lower portions 27 of the curtain material 12 and the ladder cord 1.
4. A space 28 surrounded by the upper portion 26 of No. 4, the rotary cylinder 11 and the uppermost lateral fold 13A is formed. (B) When the curtain material 12 is wound outside, it is rewound to rewind the uppermost lateral At the time when the folds 13A appear, the upper portion 26 of the ladder cord 14 is slackened and the uppermost folds 13A appear to hang down from the curtain material 12, so that the joining point 18 of the ladder cord is more than the joining point 16 of the curtain material. When the rotary cylinder 11 appears first (FIGS. 1 and 7) and continues to rotate in the direction in which the curtain material 12 is rewound, the connection point 18 between the ladder cord 14 and the rotary cylinder and the uppermost lateral fold. The joining point 17 is rolled up so that the joining points 15 and 17 of the curtain material 12 and the ladder cord 14 are aligned at the same height, and between the joining points 15 and 17, the uppermost lateral fold 13 is formed.
(A) becomes horizontal (FIGS. 2 and 7), and (c) when the ladder cord 14 is wound outside, when it is unwound and the uppermost fold 13A appears, the upper part of the curtain material 12 27 is slackened and the uppermost fold 13A appears hanging from the ladder cord 14, so that the junction 16 of the curtain material appears before the junction 18 of the ladder cord (Fig. 4), and the rotary cylinder 11 is further attached. When the ladder cord 14 is continuously rotated in the unwinding direction, the junction 16 with the rotating cylinder of the curtain material 12 and the junction 15 with the uppermost fold of the curtain material 12 are rolled up so that the curtain material 12 and the ladder cord 14 are combined. The joint points 15 and 17 are arranged at the same height, and the uppermost lateral folds 13A are set to be horizontal between the joint points 15 and 17 (FIG. 5).

For that purpose, in general, whichever of the curtain material 12 or the ladder cord 14 is wound outside, they are unwound and the connection points 15 and 1 with the uppermost fold 13A are joined.
When all 7 are at the same height, their topmost folds 1
The upper portions 26 and 27 from 3A are symmetrically divided with the rotary cylinder 11 and the uppermost lateral fold 13A sandwiched therebetween, so that the curtain fabric 12 and the ladder cord 14 and the joint points 16 and 18 of the rotary cylinder 11 are separated from each other. (FIGS. 2 and 5), and FIG. 7 illustrates an exceptional embodiment in that case.

In the roll screen 20 constructed in this way, (a) the curtain material 12 is in the form of an original roll screen which is wound up by the rotating cylinder 11 and moves up and down. Since many lateral folds (13) provided at intervals are vertically connected to each other by one of the front and back side edges thereof being held by the ladder cord 14 and the other being held by the curtain material 12, the upper and lower slats are connected. In this embodiment, the curtain material 12 is substituted for the ladder code 40 on one side of the Venetian blind that is hung by connecting the both sides of the front and back sides by the ladder code 14 and 40. The roll screen and Venetian blinds are combined to form a double structure. Therefore, the double roll screen 20 according to the present invention can be formed by joining the ladder cord 40 on one side of the Venetian blind to the curtain material 12, and the lateral folds (13) are the same as the slats 13 and the slats of the Venetian blind. It is also possible to form a substrate 23 of a certain degree of hardness by attaching it to the curtain material 12, or the slat 13 or the slat substrate 23 may be sandwiched between the lateral folds (13) of the curtain material 12 formed by folding. FIG. 8 shows a ladder cord 40 on one side of a Venetian blind.
The case where the curtain material 12 is also used is shown in FIG. 1. Each slat 13 is formed by covering the front and back of a slat substrate 23 with a decorative sheet 22, and one side edge 19 thereof is sewn to the curtain material 12 and the other one side. The edge 21 is joined to the ladder cord 14. FIG. 9 illustrates a case where the ladder cord 40 is joined and integrated with the curtain material 12, and between the front and back ladder cords 14 and 40, which are double-sided tape-woven by a narrow width knitting machine or loom, Looped connecting thread 24
One of the tape-shaped ladder cords 40 is sewn to the curtain material 12, and the slats 13 are attached to the loops of the connecting thread 24 which connects the front and back ladder cords 14 and 40.
Is plugged in.

The rotary cylinder 16 is rotatably driven by a built-in spring, a wheel mounted on an end thereof, and the like, which is pivotally supported by a bracket and is supported by a window frame or the like as in the conventional roll screen. 1 to 7, the arrow drawn around the rotating cylinder 16 indicates the direction in which the curtain material 12 is rewound, and as described above, the rotating direction of the rotating cylinder 16 is also the direction in which the curtain material 12 is wound outside. Well (FIGS. 1, 2, 3, and 7), or the direction in which the ladder cord 14 is wound outside (FIGS. 4 to 6).

When the curtain material 12 wound on the outer cylinder is rewound on the rotating cylinder 11, (a) the ladder cord 1
The upper part 26 of 4 is slack, and the uppermost lateral fold 13A appears to hang down from the curtain material 12, and in the case where the lateral fold 13 is composed of light-shielding slats, the entire surface of the curtain material 12 is covered with the slats 13. The sunlight is blocked on the front and back (FIGS. 1 and 7), and (b) When the rotary cylinder 11 continues to rotate in the rewinding direction, the joining point 1 of the ladder cord 14
8 and 17 are rolled up, and the joint points 15 and 17 of the curtain material 12 and the ladder cord 14 are aligned at the same height and the lateral fold 13
Is horizontal, and a gap 25 is formed between the upper and lower lateral folds 13 and 13 to allow sunlight to penetrate through the front and back of the curtain material 12 (FIGS. 2 and 7). (C) Further, the rotary cylinder 11 is rewound in the rewinding direction. While continuing to rotate, the joint points 18 and 17 of the ladder cord 14 are wound up higher, but the curtain material 12 is further unwound and the joint point 15 with the lateral folds 13 is lowered,
The lateral folds 13 hang down from the ladder cords 14, and the entire surface of the curtain material 12 is covered with the lateral folds 13 again.
The sun will be blocked again by the front and back of 2 (Fig. 3).

In this way, in the initial state in which the lateral folds 13 hang down from the curtain material 12 and in the final state in which the lateral folds hang down from the ladder cord 14, the front and back sides of the lateral folds 13 are inverted, and the inverted lateral folds are reversed. Since the shadow of the surface of the folds 13 appears on the surface of the curtain material 12, the roll screen 2
The design of 0 is the case where the shadow of the surface of the lateral folds 13 appears, the case where the horizontal folds 13 are horizontal and the shadow does not appear, and only the shadow of the curtain material 12 appears, and the lateral folds 13 are reversed and the back surface thereof is reversed. When the horizontal folds 13 are composed of light-shielding slats, the space between the upper and lower slats 13 and 13 can be adjusted to match the change in the sunlight on the front and back of the curtain. If the width is shorter than the width, the interior can be made a dark room by the roll screen 20. Such a roll screen 20
The change in design also occurs when the curtain material 12 wound inward is rewound on the rotating cylinder 11 (see FIG. 4).
~ 6). When the lateral folds 13 are made 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 hard to bend, as shown in FIG. 8, one side edge 19 of the slat 13 is formed. It is advisable to bond the whole to the curtain material 12.

FIG. 10 shows an application example of the present invention. The curtain material 12 is composed of a double cloth by connecting an upper cloth 32 and a lower cloth 34, and a joining point between the uppermost slat 13A and the curtain cloth 12 is formed. The length a from 15 to the junction 16 between the curtain material 12 and the rotary cylinder 11 is calculated from the junction 17 between the uppermost slat 13A and the ladder cord 14A.
Similar to the case where the length to the junction between 4A and the rotary cylinder 11 is made equal to or longer than the length to make the slat 13 difficult to bend, the uppermost connecting thread (33A) to the lower cloth 34
The length to the upper edge of the upper cloth 32 is longer than the length to the upper edge of the upper cloth 32, and the upper edges of the upper cloth 32 and the lower cloth 34 are joined to the rotating cylinder 11 to form the roll screen (20). It has a bag-shaped double structure. In the roll screen (20) in which the curtain material 12 is thus doubled with the upper cloth 32 and the lower cloth 34, one curtain material (the upper cloth 32 or the lower cloth 34) is unwound and vertically hangs down. When the rotary cylinder 11 is slightly rotated in, the upper cloth 32 and the lower cloth 34, which have been hung up on the upper cloth 32 or the lower cloth 34 by that time, are either the upper cloth 32 or the lower cloth 34. Since one of the upper cloth 33 and the lower cloth 34 changes in height, the upper cloth 33 and the lower cloth 34 are changed in height depending on the rotation angle of the rotary cylinder 11 at that time. Thus, the double roll screen 20 in which the heather pattern generated by overlapping of the textures and the patterns and other patterns formed by the combination are changed can be obtained.

【The invention's effect】

(1) According to the present invention as described above, the roll screen 20 having both the light-shielding property and the light-collecting property is obtained by combining the slats 13 having the light-shielding property and the curtain material 12 having the light-collecting property. (2) The slat 13 and the curtain material 12 are integrated into the front and back, and are wound up on the same rotating cylinder (11), and the slat 13 and the curtain material 12 do not separate during use, so the roll according to the present invention Screen 20
Can be handled like a conventional roll screen. (3) Since the shadow of the lateral folds 13 is reflected on the surface of the curtain material 12 and the shadow changes in accordance with a slight change in the rotation angle of the rotary cylinder 11, the roll screen 20 is turned in the process of reversing the lateral folds 13. The appearance of (a) Side fold 1
The case where the shadow of the surface of No. 3 appears, (b) the case where the shadow of the lateral pleat 13 hardly appears and only the shadow of the curtain 12 is emphasized, and the case where the shadow of the back side of the lateral pleat 13 appears (c) It clearly changes into three patterns and presents a new aesthetic appearance in terms of design. (4) Even if the lateral folds 13 are composed of a hard thin plate (13) that is easily bent like a slat of a Venetian blind, one side edge of the flat fold is protected by the curtain material 12 which is closely attached, so that the hard thin plate is protected from foreign matter. There is no risk of the (13) bending. (5) The slats 1 are located between the left and right edges of the curtain material 12.
Since the curtain cloth 12 is horizontally supported by the rotating cylinder 11, the curtain cloth 12 does not easily swing to the left or right when it is wound up on the rotary cylinder 11, and the left and right edge ends are aligned neatly to rotate the curtain cloth 12 into the rotary cylinder 11.
You can wind it up.
