Description

本発明は、吊桿（トップバー）１１から吊り下ろされるカーテン地１２の垂直方向に所要の間隔をおいて取り付けられた複数個の案内環１３の上下に貫通した挿通口１４に挿通したコード１５の下端をカーテン地１２に接合し、そのコード１５の上端を引いてカーテン地の下縁部１６を昇降たくし上げて上下に開閉して使用されるローマンシェードの案内環１３（図１）に関するものである。 In the present invention, a cord 15 inserted through an insertion port 14 vertically passing through a plurality of guide rings 13 attached at a predetermined interval in a vertical direction of a curtain place 12 suspended from a hanging bar (top bar) 11. The lower end of the cable is joined to the curtain base 12 and the upper end of the cord 15 is pulled up and the lower edge 16 of the curtain base is lifted up and down to open and close the guide ring 13 of the roman shade (FIG. 1) It is.

ローマンシェードの最下段の案内環１３を挿通して突き出たコード１５の下端には錘（おもり）４０が結び付けられており、コード１５を引っ張り上げるときは錘４０が最下段の案内環１３に引っ掛かってカーテン地の下縁部１６が引き上げられるようになっており、下縁部１６は、そこに取り付けられた最下段の案内環１３と錘４０を介してコード１５の下端に接合されている。コード１５の下端は、カーテン地の下縁部１６に直接縫い付けることが出来、又、カーテン地の下縁部１６に縫い付けた錘４０にコード１５を結び付け、錘４０を介してカーテン地の下縁部１６に接合することも出来る。 A weight (weight) 40 is connected to the lower end of the cord 15 protruding through the lowermost guide ring 13 of the Roman shade. When the cord 15 is pulled up, the weight 40 is caught by the lowermost guide ring 13. The lower edge 16 of the curtain base is pulled up, and the lower edge 16 is joined to the lower end of the cord 15 via the lowermost guide ring 13 and the weight 40 attached thereto. The lower end of the cord 15 can be sewn directly to the lower edge 16 of the curtain fabric, and the cord 15 is tied to the weight 40 sewn to the lower edge 16 of the curtain fabric, It can also be joined to the lower edge 16.

カーテン地の下縁には重桿（ウエイトバー）４１が取り付けられることもある。
案内環１３は、カーテン地１２に直接縫い付けることが出来る。 A weight bar 41 may be attached to the lower edge of the curtain.
The guide ring 13 can be sewn directly to the curtain fabric 12.

案内環１３をカーテン地１２に取り付け易くするために、案内環の外周面にカーテン地に係止される係止部を突設し、その係止部に上下に貫通した係合口を設け、その係合口の周縁の一部を切り欠いて切欠溝を付け、その切欠溝において向き合う一方の溝縁を尖端形にし、その尖端形の溝縁を鈎先を引っ掛けてカーテン地１２に取り付けるように構成した案内環は公知である（例えば、特許文献１参照）。 In order to make it easy to attach the guide ring 13 to the curtain base 12, a locking portion to be locked to the curtain ground is provided on the outer peripheral surface of the guide ring, and an engaging port penetrating vertically is provided in the locking portion. A part of the peripheral edge of the engagement opening is cut out to form a notch groove, one groove edge facing the notch groove is pointed, and the pointed groove edge is attached to the curtain base 12 by hooking the tip of the groove. Such a guide ring is known (see, for example, Patent Document 1).

この鈎付き案内環は、カーテン地の垂直（上下丈）方向に縫合した輪奈付きテープの輪奈に、その鈎先を引っ掛けてカーテン地に取り付けることも出来る。
その鈎先がなく、ただ係合口だけを係止部に設けた案内環では、その係合口に縫糸を通してカーテン地やテープに縫い付ける方法が取られる。 This hooked guide ring can also be attached to the curtain ground by hooking the tip of the hook on the tape with the hook stitched in the vertical (vertical length) direction of the curtain ground.
In the guide ring having no hook point and only the engagement port provided in the locking portion, a method of sewing a thread through the engagement port and sewing the curtain or tape is used.

案内環１３としては、その外周面に挿通口１４の上下両端を成す一方の開口から他方の開口へと切り欠かれて続くコード押込溝を設け、そのコード押込溝にコード１５を押し込んで挿通口１４に挿通することが出来るようにした案内環も知られている（例えば、特許文献１参照）。 As the guide ring 13, a cord pressing groove is provided on the outer peripheral surface of the insertion hole 14, which is notched from one opening forming the upper and lower ends to the other opening, and the cord 15 is pushed into the code pressing groove. There is also known a guide ring that can be inserted through the guide 14 (see, for example, Patent Document 1).

ローマンシェードでは、コード１５を引いて下縁部１６をたくし上げると、案内環１３を境にカーテン地１２が折り畳まれ、案内環１３に沿って水平方向に続く横襞３７が各案内環毎に上下数段発生する。その上下各段の横襞３７と横襞３７の間隔Ｓを一定に揃えるために、上下の案内環１３と案内環１３の各間にスペーサー３６を装着することは公知である（例えば、特許文献２参照）。 In the Roman shade, when the cord 15 is pulled and the lower edge portion 16 is lifted, the curtain land 12 is folded at the guide ring 13, and a horizontal rod 37 extending horizontally along the guide ring 13 is provided for each guide ring. Several steps are generated up and down. It is known that spacers 36 are mounted between the upper and lower guide rings 13 and the guide rings 13 in order to make the spacing S between the upper and lower horizontal bars 37 constant in the upper and lower stages (for example, Patent Documents). 2).

そのスペーサー３６は、パイプを一定寸法に切断してつくられ、コード１５を１個の案内環１３に挿通させる度に、そのコード１５を１個のスペーサー３６の内部空洞に挿通し、案内環１３の数に応じた複数個のスペーサー３６をコード１５によって数珠繋ぎにしてカーテン地１２に装着される。 The spacer 36 is formed by cutting a pipe to a certain size. Each time the cord 15 is inserted into one guide ring 13, the cord 15 is inserted into the inner cavity of one spacer 36, and the guide ring 13 is inserted. A plurality of spacers 36 corresponding to the number of the spacers 36 are connected to each other by the cord 15 and attached to the curtain base 12.

コード１５の太さは概して２ｍｍ前後であり、案内環１３の挿通口１４の内径とスペーサー２６の内部空洞の内径は、それぞれコード１５の太さの２〜３倍、即ち、概して４〜６ｍｍになっており、昇降操作時にコード１５が案内環１３やスペーサー３６に強く擦られて摩耗することがないように配慮されている。 The thickness of the cord 15 is generally about 2 mm, and the inner diameter of the insertion opening 14 of the guide ring 13 and the inner diameter of the inner cavity of the spacer 26 are respectively 2 to 3 times the thickness of the cord 15, that is, generally 4 to 6 mm. Therefore, it is considered that the cord 15 is not rubbed strongly by the guide ring 13 or the spacer 36 during the lifting operation.

このため、昇降操作時にカーテン地が前後左右に振れ動くと、その左右に振れ動いたまま案内環１３が引き上げられることになる。そうすると、垂直方向に所要の間隔をおいて取り付けられる複数個の案内環１３・13・13………のそれぞれが、カーテン地１２の側縁３５から所定の距離に取り付けられるので、昇降操作時にカーテン地の側縁３５も左右に振れ動いた状態で引き上げられることになる。 For this reason, if the curtain ground swings back and forth and right and left during the lifting operation, the guide ring 13 is pulled up while swinging left and right. Then, each of the plurality of guide rings 13, 13, 13... Attached at a predetermined interval in the vertical direction is attached at a predetermined distance from the side edge 35 of the curtain base 12. The side edge 35 of the ground is also pulled up in a state of swinging left and right.

その結果、コード１５の上端を引いてカーテン地の下縁部１６を引き上げ、垂直方向に取り付けられている複数個の案内環１３・１３・１３………が寄せ集められ、その寄せ集められて上下隣り合う案内環１３と案内環１３の間でスペーサー３６が強く挟まれて、カーテン地１２が完全にたくし上げられた状態では（図１）、垂直方向に取り付けられている複数個の各案内環１３毎に生じる各横襞３７がカーテン地の側縁３５に交わる複数条の横襞３７・３７・３７………の側端３４・３４・３４………が、垂直線上に真っ直ぐ揃わず、水平方向にズレて不揃いとなり、そのたくし上げられた状態において、看者に乱雑感を与え、ローマンシェードの美観が損なわれる。 As a result, the upper end of the cord 15 is pulled to raise the lower edge 16 of the curtain, and a plurality of guide rings 13, 13, 13... Attached in the vertical direction are gathered together. In the state where the spacer 36 is strongly sandwiched between the guide ring 13 adjacent to the upper and lower sides and the curtain base 12 is completely lifted (FIG. 1), a plurality of guides mounted in the vertical direction are provided. The side edges 34, 34, 34 ...... of the plurality of ridges 37, 37, 37,... Where each side ridge 37 generated for each ring 13 intersects the side edge 35 of the curtain ground are not aligned straight on the vertical line. In the state where they are misaligned in the horizontal direction and are raised, the viewer is messed up and the beauty of the roman shade is impaired.

そして、上下隣り合う横襞３７と横襞３７の間では、カーテン地１２がＵ字状に折り返されて垂れ下がった横襞（図示せず）がローマンシェードの使用面であるカーテン地の表側（図１の用紙の裏側）に発生するが、その表側の横襞の側端も、図１に図示する裏側の横襞３７の側端３４と同様に、垂直線上に真っ直ぐ揃わず、水平方向にズレて不揃いとなる。 Then, between the horizontal fence 37 and the horizontal fence 37 that are adjacent to each other, the horizontal surface (not shown) in which the curtain base 12 is folded back in a U-shape and hangs down is the front side of the curtain base where the roman shade is used (see FIG. 1), the side edge of the front side of the paper is not aligned straight on the vertical line and is shifted in the horizontal direction, similarly to the side edge 34 of the side paper 37 of the back side shown in FIG. Will be uneven.

その結果、特に、上下の案内環と案内環との間隔と同じ間隔で垂直方向に同じ図形が繰り返し描出されたカーテン地や、縦縞模様の描出されたカーテン地では、その描出された図形や縦縞が、Ｕ字状に垂れ下がった各横襞毎に水平方向（左右）にズレて垂直線上に真っ直ぐには揃わず、又、そのＵ字状に垂れ下がった各横襞に至るコード１５からの距離も案内環１３やスペーサー３６の位置ズレによって変化し、そのローマンシェードの厚み（前後）方向における位置ズレが生じて各Ｕ字状横襞も垂直面上に綺麗に揃わず、そのＵ字状横襞に現れる図形や縦縞のズレが看者に乱雑感を与え、ローマンシェードの使用面での美観が大きく損なわれる。 As a result, especially in curtains where the same figure is drawn repeatedly in the vertical direction at the same interval as the upper and lower guide rings, and in curtains where vertical stripes are drawn, the drawn figures and vertical stripes However, the horizontal lines (left and right) of each reed hanging in a U-shape are not aligned straight on the vertical line, and the distance from the cord 15 to each recumbent hanging in the U-shape is also It changes depending on the displacement of the guide ring 13 and the spacer 36, and the displacement of the roman shade in the thickness (front / rear) direction occurs, and the U-shaped reeds are not neatly arranged on the vertical plane. Misalignment of figures and vertical stripes appearing on the screen gives the viewer a sense of messiness, and the aesthetics of the usage of the roman shade are greatly impaired.

そこで本発明は、コード１５を引いてたくし上げた状態において、上下隣り合う横襞３７・３７・３７………の側端３４・３４・３４………が垂直線上に真っ直ぐに揃うローマンシェードを得ることを目的とする。 Accordingly, the present invention provides a roman shade in which the side ends 34, 34, 34,... Of the adjacent upper and lower horizontal cages 37, 37, 37,. The purpose is to obtain.

本発明によると、案内環の挿通口１４の上下何れか一方の開口１７の外周縁１８が上下他方の開口２０の内周縁２１よりも小さく、その大きい上下他方の開口２０の内周縁２１に囲まれる開口内部が、それよりも小さい上下一方の開口１７の外周縁１８に囲まれる開口外部１９を嵌め込むことが出来る窪み２２を構成しているので、上下隣り合う案内環１３と案内環１３が強く密着する程度にコード１５を引いてカーテン地１２をたくし上げた状態（図２）では、上下隣り合う一方の案内環１３の外周縁１８の小さい開口外部１９が、上下隣り合う他方の案内環１３の窪み２２に嵌合する。
そのようにして、垂直方向に取り付けられた複数個の全ての案内環１３・１３・１３………が、それらの上下隣り合う外周縁１８の小さい開口外部１９と窪み２２が嵌合し、桿状に接続されて垂直線上に真っ直ぐに揃い、その状態では、複数個の各案内環１３・13・13………からカーテン地１２の側縁３５・３５・３５………までの距離が一定なので、複数個の各案内環１３毎に生じる各横襞３７の側端３４・３４・３４………が垂直線上に真っ直ぐ揃い、看者に整然とした印象を与える。 According to the present invention, the outer peripheral edge 18 of one of the upper and lower openings 17 of the insertion opening 14 of the guide ring is smaller than the inner peripheral edge 21 of the upper and lower other opening 20, and is surrounded by the larger inner peripheral edge 21 of the other upper and lower opening 20. Since the inside of the opening constitutes a recess 22 into which the outside of the opening 19 surrounded by the outer peripheral edge 18 of one of the upper and lower openings 17 smaller than that can be fitted, the guide ring 13 and the guide ring 13 that are adjacent to each other are formed. In the state (FIG. 2) where the cord 15 is pulled up to the extent that the cords 15 are strongly adhered (FIG. 2), the small outer opening 19 of the outer peripheral edge 18 of one guide ring 13 adjacent to the upper and lower sides is the other guide ring adjacent to the upper and lower sides. It fits in 13 depressions 22.
In this way, all of the plurality of guide rings 13, 13, 13... Vertically attached fit the small opening outside 19 of the outer peripheral edge 18 adjacent to the upper and lower sides and the recess 22 to form a bowl shape. In this state, the distance from the plurality of guide rings 13, 13, 13,... To the side edges 35, 35, 35,. The side edges 34, 34, 34,... Of the horizontal rods 37 generated for each of the plurality of guide rings 13 are aligned straight on the vertical line, giving an orderly impression to the viewer.

本発明によると、挿通口１４の上下の開口１７と開口２０の間の長さＬが、その上下一方の開口１７の外周縁１８が上下他方の開口２０の内周縁２１よりも小さい当該上下一方の開口内部（１７）の内径ｄの２倍以上になっているので、上下隣り合う案内環１３と案内環１３が強く密着する程度にコード１５を引いてカーテン地１２をたくし上げた状態（図２）では、案内環１３は、その複数個の各案内環１３毎に生じる各横襞３７の間隔Ｓを一定に揃えるスペーサー（３６）としての機能を果たすことにもなり、その各横襞３７の間隔Ｓを一定に揃えてたくし上げることの出来るローマンシェードが得られる。 According to the present invention, the length L between the upper and lower openings 17 and 20 of the insertion opening 14 is such that the outer peripheral edge 18 of the upper and lower one opening 17 is smaller than the inner peripheral edge 21 of the upper and lower other opening 20. Since the inner diameter d of the inside of the opening (17) is at least twice as large as the inner diameter d, the curtain 15 is pulled up by pulling the cord 15 to the extent that the guide ring 13 and the guide ring 13 adjacent to each other are in close contact (see FIG. In 2), the guide ring 13 also functions as a spacer (36) for uniformly aligning the spacing S between the horizontal ribs 37 generated for each of the plurality of guide rings 13, and each horizontal rib 37 Thus, a roman shade can be obtained which can be beaten with a constant spacing S.

本発明によると、係合口２５の周縁の一部が切り欠かれた切欠溝２６において向き合う一方の溝縁が尖端形を成しており、垂直方向に同じ図形が一定間隔で繰り返し描出されたカーテン地では、その図形のレピートに合わせて鈎先２７をカーテン地に引っ掛け、或いは、輪奈付きテープをカーテン地に縫合し、その図形のレピートに合わせて鈎先２７を輪奈付きテープの輪奈に引っ掛けて案内環１３をカーテン地に取り付けることが出来、各横襞３７・３７・３７………毎に同じ図形が現われ、その各横襞３７・３７・３７………毎に現われる図形が垂直線上に真っ直ぐ揃い、看者に整然とした印象を与えるローマンシェードが得られる。 According to the present invention, one of the groove edges facing each other in the cutout groove 26 in which a part of the peripheral edge of the engagement port 25 is cut out has a pointed shape, and the same figure is repeatedly depicted in the vertical direction at regular intervals. On the ground, hook the tip 27 to the curtain ground in accordance with the repeat of the figure, or sew the tape with a wrinkle to the curtain ground, and fit the tip 27 to the wrinkle of the tape with a wrinkle according to the repeat of the figure. It is possible to attach the guide ring 13 to the curtain place by hooking it onto the curtain ground, and the same figure appears for each side wall 37, 37, 37, ..., and the figure that appears for each side wall 37, 37, 37, ... A roman shade that is straight on the vertical line and gives an orderly impression to the viewer is obtained.

本発明では、挿通口１４の上下一方の開口１７から上下他方の開口２０へと切り欠かれて続くコード押込溝２８を案内環の外周面２３に設けたので、そのコード押込溝２８を通してコード１５を挿通口１４に取り外し自在に挿通することが出来、カーテン地の取替や洗濯時にコード１５が取り外し易く、カーテン地１２に合わせてコード１５までも取替・洗濯せずに済む。 In the present invention, the cord pushing groove 28 that is notched from the upper and lower one opening 17 of the insertion opening 14 to the other upper and lower opening 20 is provided in the outer peripheral surface 23 of the guide ring. Can be removably inserted into the insertion opening 14, the cord 15 can be easily removed when the curtain place is replaced or washed, and the cord 15 is not replaced or washed together with the curtain place 12.

本発明では、開口内部の窪み２２を漸次内径ｅが小さくなる錐形断面形状（図８）に構成したので、上下隣り合う案内環１３と案内環１３が強く密着する程度にコード１５を引いてカーテン地１２をたくし上げた状態（図２）では、上下隣り合う一方の案内環１３の外周縁１８の小さい開口外部１９が、その錐形断面の斜面２９に沿って滑り込むように上下隣り合う他方の案内環１３の窪み２２に嵌合し、複数個の各案内環１３毎に生じる各横襞３７の側端３４・３４・３４………が垂直線上に確実に真っ直ぐに揃い、又、各案内環１３・１３・１３………毎にローマンシェードの使用面（図２の用紙の裏側）に垂れ下がって生じる各Ｕ字状横襞に至るコード１５からの距離も一定に揃い、従って、その各Ｕ字状横襞も垂直面上に綺麗に揃い、そのたくし上げられたローマンシェードがスッキリした清楚な美観を呈するようになる。 In the present invention, since the depression 22 inside the opening has a conical cross-sectional shape (FIG. 8) in which the inner diameter e gradually decreases, the cord 15 is pulled to such an extent that the guide rings 13 adjacent to each other are in close contact with each other. In the state in which the curtain place 12 is lifted up (FIG. 2), the other side of the upper and lower sides adjacent to each other so that the small outer opening 19 of the outer peripheral edge 18 of one of the upper and lower adjacent guide rings 13 slides along the inclined surface 29 of the conical section. The side edges 34, 34, 34... Of the horizontal rods 37 generated in each of the plurality of guide rings 13 are surely aligned straight on the vertical line. The distance from the cord 15 to each U-shaped recumbent that hangs down on the use surface of the roman shade (the back side of the paper in FIG. 2) for each guide ring 13, 13, 13,... Each U-shaped reed is neatly aligned on the vertical surface. Its tucked raised Roman shade is to assume a neat and clean appearance that was refreshing.

それとは逆に、上下一方の開口２０の窪み２２に嵌め込む上下他方の開口１７の開口外部１９を、その先端の開口１７に近づくにつれて外径Ｄが小さくなる尖端形の等脚台形断面形状にする場合、つまり、外周縁１８の小さい開口１７の外周面である開口外部１９にテーパーを付ける場合も、窪み２２の周縁に突き当たることなく開口１７の開口外部１９が窪み２２に嵌まり込むので、複数個の各案内環１３毎に生じる各横襞３７の側端３４・３４・３４………が垂直線上に真っ直ぐに揃い、又、各案内環１３・１３・１３………毎にローマンシェードの使用面（図２の用紙の裏側）に生じる各Ｕ字状横襞も垂直面上に綺麗に揃うようになる。 On the contrary, the outer opening 19 of the upper and lower openings 17 fitted into the recess 22 of the upper and lower openings 20 has a pointed isosceles trapezoidal cross-sectional shape in which the outer diameter D decreases as it approaches the opening 17 at the tip. In other words, when the outside of the opening 19 that is the outer peripheral surface of the opening 17 having a small outer peripheral edge 18 is tapered, the outside of the opening 19 of the opening 17 fits into the indent 22 without hitting the periphery of the indent 22. The side edges 34, 34, 34,... Of the horizontal rods 37 generated for each of the plurality of guide rings 13 are aligned straight on the vertical line, and the roman shade for each guide ring 13, 13, 13,. Each U-shaped reed generated on the use surface (the back side of the paper in FIG. 2) is also neatly aligned on the vertical surface.

本発明では、係止部２４が偏って突設され窪み２２が形成されている開口側（２０）と、その窪み２２に嵌め込むことが出来る外周縁１８の小さい開口外部１９の形成されている開口側（１７）とに案内環１３を上下に２分割し、窪み２２に嵌め込むことが出来る外周縁１８の小さい開口外部１９の形成されている開口側（１７）の分割された案内環（１３ｂ）の長さＸを挿通口１４ｂの内径ｄの２倍以上の円筒１３ｂにしたので、その円筒１３ｂを取り代えて上下の横襞間３７・３７の間隔Ｓを調整することが出来、又、他方の係止部２４が偏って突設されていて窪み２２が形成されている開口側（２０）のリング１３ａだけを在来の案内環として既存のローマンシェードに適用することも出来る（図４）。 In the present invention, an opening side (20) in which the locking portion 24 is projected in a biased manner and a recess 22 is formed, and an outer opening 19 having a small outer peripheral edge 18 that can be fitted into the recess 22 is formed. The guide ring 13 is vertically divided into two on the opening side (17), and the divided guide ring (17) on the opening side (17) in which the outer opening 19 having a small outer peripheral edge 18 that can be fitted into the recess 22 is formed ( Since the length X of 13b) is made to be a cylinder 13b that is twice or more the inner diameter d of the insertion port 14b, the cylinder 13b can be replaced to adjust the distance S between the upper and lower lateral ribs 37, 37. Further, only the ring 13a on the opening side (20) in which the other locking portion 24 is protruded in a biased manner and the recess 22 is formed can be applied to an existing roman shade as a conventional guide ring (FIG. 4).

そのように、案内環１３をリング１３ａと円筒１３ｂに２分割すると、在来のスペーサー３６（図１）と同様に、パイプを一定寸法に切断して円筒１３ｂを調製することが出来るので、係止部２４が突き出ており、挿通口１４の内径ｄが窪み２２で広くなった形状が複雑なリング１３ａだけをプラスチックによって射出成形するだけで済み、そのプラスチック射出成形の金型代が安くつき、案内環１３のコストダウンを図ることが出来る点でも有利である。 As described above, when the guide ring 13 is divided into the ring 13a and the cylinder 13b, similarly to the conventional spacer 36 (FIG. 1), the pipe 13 can be cut to a certain size to prepare the cylinder 13b. Only the ring 13a having a complicated shape in which the stop portion 24 protrudes and the inner diameter d of the insertion opening 14 is widened by the depression 22 only needs to be injection-molded by plastic, and the mold cost of the plastic injection molding is reduced, This is also advantageous in that the cost of the guide ring 13 can be reduced.

そして、挿通口１４ａの上下両端の開口２０ａ・２０ｂがそれぞれ窪み２２ａ・２２ｂの形成されている開口側（２０）のリング１３ａと、その窪み２２に開口外部１９を嵌め込むことが出来る開口側（１７）の円筒１３ｂに案内環１３を２分割する場合でも、その上下両端の窪み２２ａ・２２ｂを、挿通口１４ａの奥に進むにつれて内径ｅが漸次小さくなるラッパ乃至擂鉢形の錐形断面形状にすると、上下隣り合うリング１３ａとリング１３ａの間で円筒１３ｂが強く挟まれる程度にコード１５を引いてカーテン地１２をたくし上げた状態（図２）では、分割された円筒１３ｂが、その錐形断面の斜面２９に沿って滑り込むように窪み２２ａ・２２ｂに嵌合し、複数個の各案内環毎に生じる各横襞３７の側端３４・３４・３４………を、垂直線上に真っ直ぐに確実に揃えることが出来る（図７）。 Then, the openings 20a and 20b at the upper and lower ends of the insertion opening 14a are respectively the ring 13a on the opening side (20) in which the depressions 22a and 22b are formed, and the opening side on which the opening exterior 19 can be fitted into the depression 22 ( 17) Even when the guide ring 13 is divided into two cylinders 13b, the recesses 22a and 22b at the upper and lower ends thereof are formed into a trumpet or bowl-shaped cone-shaped cross-sectional shape in which the inner diameter e gradually decreases as the depth of the insertion port 14a increases. Then, in a state where the cord 15 is pulled so that the cylinder 13b is strongly sandwiched between the ring 13a and the ring 13a that are adjacent to each other (FIG. 2), the divided cylinder 13b has its cone shape. Fit into the recesses 22a and 22b so as to slide along the slope 29 of the cross section, and the side ends 34, 34, 34,... Straight reliably align it can be in line (Fig. 7).

それとは逆に、リング１３ａの窪み２２ａ（２２ｂ）に嵌め込む円筒１３ｂの上下両端の開口外部（１９・１９）にテーパーを付け、その開口外部（１９・１９）を円筒１３ｂの上下両先端に近づくにつれて外径Ｄが小さくなる尖端形の等脚台形断面形状にする場合も、窪み２２ａ（２２ｂ）の周縁に突き当たることなく円筒１３ｂがリング１３ａの窪み２２ａ（２２ｂ）に嵌まり込むので、複数個の各案内環１３毎に生じる各横襞３７の側端３４・３４・３４………が垂直線上に真っ直ぐ揃う。 Conversely, the openings (19, 19) at the upper and lower ends of the cylinder 13b fitted into the recess 22a (22b) of the ring 13a are tapered, and the openings (19, 19) at the upper and lower ends of the cylinder 13b. Even in the case of a pointed trapezoidal trapezoidal cross-sectional shape in which the outer diameter D decreases as it approaches, the cylinder 13b fits into the recess 22a (22b) of the ring 13a without hitting the periphery of the recess 22a (22b). The side ends 34, 34, 34... Of each horizontal bar 37 generated for each guide ring 13 are aligned straight on the vertical line.

このように、本発明によると、コード１５を引いてたくし上げた状態において、上下隣り合う横襞３７・３７・３７………の側端３４・３４・３４………が垂直線上に真っ直ぐに揃い、特に、上下の案内環と案内環との間隔と同じ間隔で垂直方向に同じ図形が繰り返し描出されたカーテン地や、縦縞模様の描出されたカーテン地では、その描出された図形や縦縞が、Ｕ字状に垂れ下がった各横襞毎に水平方向（左右）にズレることなく、垂直線上に真っ直ぐ揃い、又、各案内環１３・１３・１３………毎にローマンシェードの使用面（図２の用紙の裏側）に生じる各Ｕ字状横襞も同一面上に綺麗に揃い、たくし上げられてスッキリした清楚な印象を与えるローマンシェードを得ることが出来る。 As described above, according to the present invention, in the state where the cord 15 is pulled and lifted, the side ends 34, 34, 34,... In particular, in curtains where the same figure is repeatedly drawn in the vertical direction at the same interval as the guide ring between the upper and lower guide rings, and in curtains where a vertical stripe pattern is drawn, the drawn figures and vertical stripes The horizontal shades (left and right) are not shifted in the horizontal direction (left and right) for each recumbent hanging in a U-shape, and are aligned straight on the vertical line. Also, the usage surface of the roman shade for each guide ring 13, 13, 13. The U-shaped reeds generated on the back side of the sheet 2 are also neatly arranged on the same surface, and a roman shade that can be tucked up to give a clean and neat impression can be obtained.

図２は、本発明に係るローマンシェードの使用面の裏側を図示する。カーテン地１２は、その上縁を面ファスアーやフックを介して吊桿１１に着脱自在に接合して吊り下ろされる。吊桿１１の内部は吊桿の長さ方向に続く溝となっており、３９は、その溝にコード１５を導入する案内隙間であり、コード１５によって引き上げられる最上段の案内環１３は、その案内隙間３９の周りに突き当って止まる。吊桿１１の端部には、コード１５の静動を規制するストッパーが装着される。３６は、その端部のストッパーへとコード１５を導く案内ロールである。吊桿（トップバー）１１には、横引きカーテンを吊るすランナー走行溝の付いたチャンネル形カーテンレールを利用することが出来る。 FIG. 2 illustrates the back side of the working surface of the roman shade according to the present invention. The curtain base 12 is suspended by detachably joining the upper edge of the curtain base 12 to the hanging rod 11 via a surface fastener or a hook. The inside of the hanging rod 11 is a groove continuing in the length direction of the hanging rod, 39 is a guide gap for introducing the cord 15 into the groove, and the uppermost guide ring 13 pulled up by the cord 15 is It stops around the guide gap 39. A stopper that restricts the static movement of the cord 15 is attached to the end of the hanging rod 11. Reference numeral 36 denotes a guide roll for guiding the cord 15 to a stopper at its end. The hanging bar (top bar) 11 can be a channel curtain rail having a runner running groove for hanging a horizontal curtain.

案内環１３をリング１３ａと円筒１３ｂに分割して構成する場合を除き、係止部２４は、外周縁１８の小さい開口外部１９に偏った部位に突設しても（図６）、又、窪み２２のある開口２０に偏った部位に突設しても（図３・図８）、或いは又、上下の開口１７・２０の中間部位に突設してもよい（図５）。 Except for the case where the guide ring 13 is divided into a ring 13a and a cylinder 13b, the locking portion 24 may protrude from a portion of the outer peripheral edge 18 that is biased toward the small outer opening 19 (FIG. 6). The projection may be provided at a portion biased to the opening 20 having the depression 22 (FIGS. 3 and 8), or may be provided at an intermediate portion between the upper and lower openings 17 and 20 (FIG. 5).

コード押込溝２８は、挿通口１４の上下一方の開口１７から上下他方の開口２０へと外周面２３の円周方向に曲折して続くように形成することも出来る（図６）。
そのようにコード押込溝２８を曲折させると、押込溝２８とコード１５が一部分で交叉して完全には平行にならないので、押込溝２８の溝幅Ｔをコード１５の太さよりも広くしても、コード１５が押込溝２８から外れることがなく、又、コード１５を挿通口１４へと押し込み易くなるので好都合である。 The cord pushing groove 28 can also be formed so as to bend in the circumferential direction of the outer peripheral surface 23 from one upper and lower opening 17 of the insertion opening 14 to the other upper and lower opening 20 (FIG. 6).
If the cord pushing groove 28 is bent in such a manner, the pushing groove 28 and the cord 15 partially cross each other and do not become completely parallel. Therefore, even if the groove width T of the pushing groove 28 is wider than the thickness of the cord 15. This is advantageous because the cord 15 does not come off the push groove 28 and the cord 15 can be easily pushed into the insertion opening 14.

窪み２２の断面を、挿通口１４の奥に進むにつれて内径ｅが漸次小さくなるラッパ形ないし擂鉢形の錐形断面形状にするのは、部分的であってもよい。即ち、挿通口１４の奥に進むにつれて内径ｅが漸次小さくなるラッパ形ないし擂鉢形の錐形断面形状となる斜面２９を、挿通口１４の軸芯３０を中心に放射状に窪み２２の内部周面に形成すれば十分である（図７）。従って、窪み２２は、それを囲む外周縁や内周縁２１が、開口２０の周囲に部分的に突き出た突起の頂端によって点状に描かれる形状にすることも出来る。 It may be partial to make the cross section of the recess 22 into a trumpet-shaped or bowl-shaped conical cross-sectional shape in which the inner diameter e gradually decreases as it goes deeper into the insertion opening 14. That is, a slope 29 having a trumpet-shaped or bowl-shaped cone-shaped cross-sectional shape in which the inner diameter e gradually decreases toward the depth of the insertion opening 14, and the inner peripheral surface of the depression 22 radially about the axis 30 of the insertion opening 14. It is sufficient to form (FIG. 7). Therefore, the recess 22 can have a shape in which an outer peripheral edge or an inner peripheral edge 21 surrounding the recess 22 is drawn in a dot shape by a top end of a protrusion partially protruding around the opening 20.

外周縁１８の小さい開口１７の開口外部１９が窪み２２の周縁に突き当たらないようにするためには、外周縁１８の小さい開口１７の外周面である開口外部１９にテーパーを付け、又、窪み２２の内周面にもテーパー（斜面２９）を付けて擂鉢形の錐形断面形状にすると共に、挿通口の内径ｄと外径Ｄとコード１５の太さ（外径）Ｚとの関係において、窪み２２の最大内径ｅを、ｅ≧Ｄ＋ｄ−Ｚに設定するとよい。 In order to prevent the outer opening 19 of the small opening 17 of the outer peripheral edge 18 from striking the peripheral edge of the recess 22, the outer opening 19 that is the outer peripheral surface of the small opening 17 of the outer peripheral edge 18 is tapered and the hollow is formed. In addition, a taper (slope 29) is also provided on the inner peripheral surface of 22 to form a bowl-shaped cone-shaped cross section, and the relationship between the inner diameter d and outer diameter D of the insertion port and the thickness (outer diameter) Z of the cord 15 The maximum inner diameter e of the recess 22 may be set to e ≧ D + d−Z.
