Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a Roman shade curtain in which curtain fabric is regularly folded at regular intervals.
[0002]
[Prior art]
Office windows are often fitted with blinds to block out direct sunlight. As a main form of the blind, a plurality of slender curved blades are suspended by a string, and are horizontally arranged at equal intervals. Then, the inclination angle of the blade can be adjusted by operating the string, and the incidence of light from the outside can be adjusted at this inclination angle. Also, it can be fully opened by operating and pulling up the string.
[0003]
On the other hand, a vertical blind in which a plurality of blades are vertically arranged and suspended is often used. The direction of the blind is changed by rotating the blade about the vertical axis, so that light from the outside or light can be blocked. However, although blinds composed of these plastic blades are suitable for offices in buildings, they do not fit in rooms for ordinary houses, especially Japanese-style rooms.
[0004]
Therefore, curtains and Roman shade curtains are often attached to rooms for ordinary houses. The curtain is suspended from the upper rail, and can be opened and closed along the upper rail. One Roman shade curtain is suspended by a string and can be lifted upward. The present invention relates to the Roman shade curtain, and FIG. 7 shows a conventionally used Roman shade curtain.
[0005]
As shown in the figure, (a) shows a front view of a blind curtain, and (b) shows a back view of a back side. An upper edge of a rectangular curtain fabric 1 is fixed to an upper rail 2, and a lower rail 3 is located at a lower end. Is installed. On the back side of the curtain fabric 1, rings 4a, 4a,... Are arranged in the vertical direction at equal intervals, and rings 4b, 4b,. 4c are also arranged at equal intervals in the vertical direction.
[0006]
That is, the rings 4a, 4a,..., 4b, 4b... And 4c, 4c. are doing. The string 5a is inserted through the rings 4a, 4a,..., The string 5b is inserted through the rings 4b, 4b,..., And the string 5c is inserted through the rings 4c, 4c,. These strings 5a, 5b, 5c are fixed to the lowermost rings 4a, 4b, 4c, respectively.
[0007]
By the way, these three strings 5a, 5b, 5c extend horizontally via guide members 6a, 6b, 6c attached to the upper rail 2, and pass through a lock member 7 provided next to the guide member 6a. As a result, the operation string 8 hangs down. Therefore, if the operation string 8 is pulled downward, the strings 5a, 5b, 5c are pulled, and the curtain fabric 1 rises, so that light from outside can be turned on. The operation cord 8 is configured to be locked at an arbitrary position by the lock member 7.
[0008]
Then, when the lock is released, the curtain fabric 1 is lowered by the weight of the curtain fabric 1 and the lower rail 3, and the curtain fabric 1 is stretched as shown in FIG. By the way, if the curtain fabric 1 is lifted by pulling the operation cord 8, the curtain fabric 1 is folded. However, when the strings 5a, 5b, 5c are pulled, the rings 4a, 4a,..., The rings 4b, 4b,. Then, as shown in FIG. 8, the curtain fabric 1 is folded, but each ring portion is compressed and folded in a cramped state, so that the entire fabric is not in a regular folded form and the appearance is impaired.
[0009]
[Problems to be solved by the invention]
As described above, the conventional Roman shade curtain has the above-described problems. The problem to be solved by the present invention is this problem. To provide a Roman shade curtain in which, when the curtain is pulled up, the whole is folded regularly so that the appearance is not impaired.
[0010]
[Means for solving the problem]
The basic structure of the Roman shade curtain according to the present invention is the same as that shown in FIG. 7, and the upper edge of the curtain fabric is fixed to the upper rail, and the rings are arranged at equal intervals in the vertical direction. The ring is configured by inserting a string. In the present invention, a spacer is interposed between the rings so that the rings do not come into contact with each other when the string is pulled and the curtain fabric is folded. The length of the spacer corresponds to the folding pitch of the curtain fabric, and is generally slightly larger than the folding pitch.
[0011]
Therefore, when the curtain fabric is folded, the pitch between the rings and the folding pitch of the curtain fabric at a position distant from the ring have substantially the same length, and the curtain fabric is folded stepwise with a constant interval. . That is, only the portion where the ring is attached is extremely compressed, so that the folding pitch is not reduced, and the entire curtain fabric is uniformly folded. Here, not only the case where the spacer is attached as a separate part between the rings, but also a ring having a spacer portion in which the ring and the spacer are integrated can be attached to the curtain fabric. The shape of the spacer is not particularly limited. Hereinafter, embodiments according to the present invention will be described in detail with reference to the drawings.
[0012]
【Example】
FIG. 1 shows a specific example of the ring 4, which has a substantially elliptical plate shape made of resin. On one side, a circular string hole 9 is provided so as to penetrate therethrough, and on the opposite side, an oval stopper hole 10 is formed. However, since a notch 16 is formed in the blind hole 10 as shown in the figure and communicates with the outer periphery, the notch 16 is attached to the tape sewn on the back side of the curtain fabric 1. The stop hole 10 can be locked through the hole. As described above, the ring 4 is attached to the back side of the curtain fabric 1 by using the blind hole 10, and the string 5 is inserted into the string hole 9 of the attached ring 4.
[0013]
FIG. 2 is a specific example showing a spacer 11 interposed between the rings 4, 4,..., And the spacer 11 shown in the figure is a pipe. Here, the pipe outer diameter D of the spacer 11 satisfies D> d so as not to fit in the string hole 9 of the ring 4. Of course, even when the string holes 9 are not circular but oval, any size is acceptable as long as the spacer 11 does not fit into the string holes 9.
[0014]
Accordingly, when the string 5 is pulled and the curtain fabric 1 is lifted and folded, as shown in FIG. 3, the distance between the rings 4, 4,... Is increased by the spacers 11, 11,. The folding pitch P at the part becomes large. The folding pitch P is the same as the folding pitch of the curtain fabric 1 at a position away from the rings 4, 4,..., And the entire curtain fabric 1 is folded at equal intervals. That is, the absence of the spacers 11, 11, as in the prior art, causes the rings 4, 4,... To abut against each other, and as a result, the pitch between the rings becomes small, and the folding pitch P of the curtain fabric 1 with respect to other parts is smaller than that. It can be prevented from becoming smaller.
[0015]
FIG. 4 shows a ring 12 with a spacer according to the present invention. The ring 12 is an integrated part obtained by combining the ring 4 and the spacer 11 shown in FIG. 1 and is formed by injection molding. Then, it is composed of the ring portion 13 and the spacer portion 14, and is fixed to the back side of the curtain fabric 1 through the blind hole 10 of the ring portion 13. The string 5 is inserted into the string holes 15 of the rings 12, 12...
[0016]
If the ring 12 is fixed to the curtain fabric 1 and the operation cord 8 is pulled to fold the curtain fabric 1, the pitch between the rings and the folding pitch P are made constant as shown in FIG. Folds in.
[0017]
Incidentally, the shape of the spacer 11 interposed between the rings 4, 4,... And the shape of the spacer portion 14 integrally formed with the ring 12 are not limited to the pipe shape. For example, a spacer having a substantially U-shape shown in FIG. 5 or a spacer combining a plurality of rings shown in FIG. 6 can be used. Of course, a hole through which the string is inserted is necessary.
[0018]
As described above, the Roman shade curtain of the present invention has a spacer interposed between rings through which a string is inserted, or a ring having a spacer portion fixed thereto, and has the following effects. Can be done.
[0019]
【The invention's effect】
In the Roman shade curtain according to the present invention, a spacer is interposed between the rings fixed to the back side and through which the string is inserted. Alternatively, since the ring having the spacer portion is attached, the curtain is regularly folded in steps at regular intervals when the curtain is pulled up, and the appearance of the folded state is improved. That is, since the spacer is interposed between the rings, the rings are in contact with each other, and the folding pitch of this portion does not become smaller than that of the other portions. That is, since the spacer is interposed so as to have the same size as the folding pitch of the curtain cloth, the ring mounting portion is not extremely compressed and the folding pitch does not become small.
