DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is disclosed in JP-A-54-89876, JP-B-56-8536, and JP-A-KAI-6.
The present invention relates to the Roman shade described in 1-126882, Jikkai 61-126883 and the like.

[Conventional technology]

As shown in Japanese Utility Model Publication No. 61-126882 and Japanese Utility Model Publication No. 61-126883, Roman shade has a plurality of reinforcing tapes sewn vertically long at required intervals in the width direction of the curtain fabric. There are lateral folds formed at required intervals in the longitudinal direction, and the lateral folds form a lateral fold pattern continuing in the lateral width direction, which is usually called a web-style roman shade.

As a tape to be sewn to a web-style roman shade of this kind, one in which thread yarns are attached so that they can be removed and entangled at required intervals in the length direction of the tape material is disclosed in JP-A-60-114214. Is disclosed in.

[Problems to be solved by the device]

The tape according to the above-mentioned invention is sewn to a curtain material, and then a part of the drawing thread is pulled out from the tape material to be shorter than the tape material, and the tape material is formed on the tape material according to the difference in length. The horizontal wrinkles are squeezed in the longitudinal direction to form a lateral fold, and the folds are sewn together for use.

However, in order to prevent the side folds protruding to the front side from being flatly sewn at that time, it was necessary to sew the folds formed on the back side of the curtain fabric so that the folds could be sewn together, which required a great deal of labor.

[Purpose of device]

Therefore, an object of the present invention is to easily tailor a web style roman shade by applying the above-mentioned prior invention technique.

[Constitution of device]

The present invention achieves the above-mentioned object, and requires a plurality of reinforcing tapes 12 sewn vertically in a longitudinal direction at a required interval L in the lateral direction M of the curtain material 11 in the longitudinal direction N. Interval l
A web style in which a horizontal fold 13 is attached at a position, and the horizontal fold 13 forms a horizontal fold pattern 14 continuing in the lateral width direction M on the curtain material 11.
The Roman shade 15, the drawing thread 17 is attached to the reinforcing tape 12 straightly in the length direction N so that a part of the tape material 16 is sewn, and is used as a crest A bag cavity 19 penetrating in the lateral width direction M is formed in the vicinity of an entangled portion 18 of the tape material 16 in which the thread 17 is entangled in a scooping manner at a required interval p in the length direction of the tape material 16. And the elevating cord in the length direction N of the tape material 16
A looper 22 having an insertion hole 21 through which 20 can be inserted is formed in the vicinity of the entangled portion 18, and the total length of the drawing thread 17 is shorter than the total length of the tape material 16, and a tape is formed according to the difference in length. The lateral folds 23 generated on the ground 16 are gathered between the required two confounding points 24 and 25 to form the lateral folds 13, and the hook shafts 27 are arranged in parallel.
And hooks 28 facing each other are connected to the bent corner portion 33 to form two J-shaped or U-shaped hooks 26 and 26 'with their respective hook shafts (2
7) and the hook head (28) sideways, and the two hooks 26 and 2
The 6'hook shaft (27) is positioned on the outside and the hook head (28) is positioned on the inside so that the hooks are located above and below the hook 2
The end of the hook shaft 27 of 6 ′ and the end of the hook shaft 27 of the hook 26 located at the lower end are connected by the connecting portion 29, and the tip of the hook head 28 ′ of the upper hook 26 ′ and the lower hook 26 are connected. One of the upper and lower bag-like cavities 31 and 32, in which a hook 30 formed by opening a gap between the hook 28 and the connecting portion 29 sandwiches the lateral folds 13 of the tape gathered above and below. One hook 26 'of the hook 30 is inserted into the hollow cavity 31 so that the hook shaft 27' engages with the one bag-shaped cavity 31 and the other hook of the hook 30 is hooked to the other bag-shaped cavity 32. 26 is inserted and its hook 27 engages with the other bag-shaped cavity 32 and the tape material
The upper and lower bag-shaped cavities 31 are attached to the bag 16 by the hook 30.
And 32 are connected to each other, so that the lateral folds 13 are set, and the distance a between the tip of the hook head 28 and the connecting portion 29 that connects the upper and lower hook shafts 26 and 26 'of the hook 30 and the hook shaft 27 are set. B, the protrusion length c of the hook head 28, the outer width d from the hook shaft 27 to the hook head 28, the gap e between the hook shaft 27 and the hook head 28, and the bag-shaped cavity 19
The maximum aperture f in the expanded state, the body length g, and the body wall thickness h have a relationship of h <d <a <g <c <b, e <f. is there.

It is recommended that the interval q between the entangled points 18 that entangle with the tape material 16 so as to sew the squeezing thread 17 is 2 to 5 cm, and the interval q is, for example, 2 cm, 3 cm, 4 cm, 3 cm, 2 cm. In addition, the height of the lateral folds 13 can be sequentially changed by changing the height from 2 cm to 4 cm in a certain cycle.

The interval p between the bag-shaped cavities 19 is set to be larger than the interval q between the entangled portions 18, in which case the bag-shaped cavities that are repeatedly formed.
In the case where the drawing yarn 17 is entangled with the tape material 16 at several points within the interval p of 19, and the entanglement interval q is to be changed, the cycle in which the change is repeated is a bag-like empty space. Torso 19
It is advisable to match the interval p of (that is, p = Σq).

When the tape 12 is woven by a ribbon loom, a thick warp is woven as a thread 17 for the drawing so that it is long enough to protrude from the tape fabric 16, and the Wanna 22 has a thick weft tape between the left and right ear ends. The bag-like cavities 19 may be woven so that they float above the ground 16, and the bag-shaped cavities 19 may be formed by weaving so that a small surface material floats on the surface of the tape ground 16 due to the ventilation structure.

From the hook shaft 27 (27 ') of the two hooks 26, 26' of the hook 30 to the hook head
The bent corner portion 33 (33 ') continuing to 28 (28') may have the same right and left directions as shown in FIGS. 3 and 5, or may have different left and right directions as shown in FIG. You may turn it.

The distance R between the two hooks 26 and 26 'is defined by the lateral folds to be formed between them.
It can be changed at any time by the number of 13, and depending on the size of the interval R, the connecting portion 29 may be extended so as to fill the gap as shown in FIGS. 3 and 4.

In that case, if the cut groove 35 is put in the overhanging portion 34 in the same lateral direction as the hook shaft 27, the tension applied between the upper and lower hooks 26 and 26 'is bent in a U shape by sandwiching the cut groove 35. Connecting part 29
This is convenient because it is alleviated by the bending of the knuckle, and it is also convenient in that the knuckle 22 can be inserted into the cut groove 35 as shown in FIG.

[Effect of device]

The lateral folds 13 are formed as a difference in length between the tape material 16 and the squeezing thread 17, and the folds 13 are unstable because they can be freely displaced in the length direction N at the beginning when the wrinkles 23 are just squeezed. But,
When the bag-shaped cavities 31 and 32 before and after sandwiching this are connected by the hook 30, there is no difference in length between the drawing yarn 17 and the tape material 16 between the adjacent hooks. Fold
No. 13 cannot move in the length direction, and it is set as it is and enters a stable state where it does not move.

This set of side folds 13 is just a hook 26.2 on each end of the hook 30.
All you have to do is to insert the 6'into the bag-shaped cavities 31 and 32 and hook it with the hook shaft 27.After that, the hook shaft 27 is oriented sideways like the bag-shaped cavity 19, so the bag-shaped cavity 19 is always wide. It will be spread in the direction M. In addition, the connection part 29 and the hook head 28 space a, the hook shaft
27 protruding length b, hook 28 protruding length c, hook shaft 27 to hook
The outer width d up to 28, the gap e between the hook shaft 27 and the hook head 28, the maximum diameter f of the bag-shaped cavity 19, the body length g, and the wall thickness h are h <d <a <. Since the relationship of g <c <b and e <f is satisfied, the hook 30 is not detached by the tape 12 during the process of raising and lowering the web style roman shade 15.

On the other hand, since the bag-shaped cavity 19 is to be picked up with a fingertip and introduced between the hook shaft 27 and the hook head 28 so that the hook 30 is mounted, the hook 30 is detached from the bag-shaped cavity 19 in the reverse order. Therefore, if the web style roman shade 15 is dirty and you want to wash it, remove the hook 30 from the curtain material 11 and wash it with the original flat fabric without the folds 13 and then wrinkle it. Can be stretched and spread and ironed, then hook 30 can be reattached to create a web style roman shade 15, which will keep you beautiful and clean at all times.

As described above, the web-style roman shade 15 according to the present invention is practically convenient in terms of tailoring, using and caring for it.
