Description

横型ブラインドHorizontal blind
　この発明は、昇降テープとラダーコードとによって、スラットの昇降操作及び角度調節操作を行うことができる横型ブラインドに関するものである。 This invention relates to a horizontal blind that can be moved up and down and angle-adjusted by a lifting tape and a ladder cord.
　横型ブラインドでは、昇降コードを用いて、スラットを昇降させる構成のものが一般的であるが、太さのある昇降コードの代わりに、薄い昇降テープを用いてスラットを昇降させる横型ブラインドも存在する（例えば特許文献１参照）。このように、薄い昇降テープを用いるのは、次のような理由による。すなわち、全高（高さ）のあるブラインド製品の場合や、全幅の短い（ヘッドボックス幅の短い）ブラインド製品（特に電動）の場合には、昇降コードを用いると、ヘッドボックス内の巻取りドラムの径がコードの太さ分増えてしまったり、専用の巻取コーンが必要となったりする。このため、ヘッドボックスの大きさや巻取コーンのスペース確保等が問題となる。これに対して、昇降テープの場合には、巻取りドラムにそのまま重ねて巻取っても厚みがそれほど増えない。このため、専用の長い巻取コーンを用いることなく、そのまま昇降テープを重ねて巻き取ることが可能となるというメリットがある。かかる観点から、全高のあるブラインド製品の場合や、全幅の短いブラインド製品の場合には、昇降テープを用いて、製品（特にヘッドボックス）の小型化や部品点数の削減を図ることが多い。 The horizontal blind is generally configured to lift and lower the slat using a lifting cord, but there is also a horizontal blind that lifts and lowers the slat using a thin lifting tape instead of a thick lifting cord ( For example, see Patent Document 1). The reason why the thin lifting tape is used is as follows. In other words, in the case of a blind product with a full height (height) or a blind product with a short full width (short head box width) (especially electric), the use of the lifting / lowering cords makes it possible to The diameter increases by the thickness of the cord, or a special winding cone is required. For this reason, the size of the head box and the space for the winding cone are problematic. On the other hand, in the case of an elevating tape, the thickness does not increase so much even if it is wound on the winding drum as it is. For this reason, there is an advantage that it is possible to directly wind up the lifting tape without using a special long winding cone. From this point of view, in the case of a blind product with an overall height or a blind product with a short overall width, a lifting tape is often used to reduce the size of the product (particularly the head box) and reduce the number of parts.

　しかし、上記した従来の横型ブラインドでは、次のような問題がある。すなわち、昇降テープを用いた横型ブラインドでは、特許文献１に記載のブラインドのように、昇降テープを、スラットの幅方向中央部に設けられたテープ孔に挿通した状態で、ボトムレールに接続する構成をとるのが一般的である。しかし、このような構成をとると、スラットを全閉状態にしたときに、日射光がスラット中央部に開けられたテープ孔から漏れ、ブラインドの遮光機能が大きく損なわれてしまうおそれがあった。 However, the conventional horizontal blinds described above have the following problems. That is, in the horizontal blind using the lifting tape, as in the blind described in Patent Document 1, the lifting tape is connected to the bottom rail in a state of being inserted into the tape hole provided in the center portion in the width direction of the slat. It is common to take However, when such a configuration is adopted, when the slat is fully closed, solar light leaks from the tape hole formed in the central portion of the slat, and the light shielding function of the blind may be greatly impaired.
　この発明は、上述した課題を解決するためになされたもので、昇降テープを用いて、製品の小型化や部品点数の削減を図ることができると共に、ほぼ完全な遮光が可能な横型ブラインドを提供することを目的とする。 The present invention has been made to solve the above-described problems, and provides a horizontal blind capable of reducing the size of the product and reducing the number of parts by using an elevating tape, and capable of almost complete light shielding. The purpose is to do.
　上記課題を解決するために、本発明は、ヘッドボックスから引き出されてボトムレールに下端接続された複数のラダーコードによって、複数段のスラットを角度調整可能に支持すると共に、ヘッドボックスから引き出されてボトムレールに下端接続された複数の昇降テープによって、スラットを昇降させることが可能な横型ブラインドであって、上記スラットの少なくとも一段の縁部に一以上の空間部を設け、当該空間部が各スラットの閉時に上段又は下段のスラットの縁部と重なることで塞がれるよう構成すると共に、各昇降テープを各空間部内に挿通した構成とする。かかる構成により、昇降テープによって、複数段のスラットを昇降させることができる。そして、ラダーコードによって、スラットの角度を調整し、スラットを全閉状態にすることができる。この全閉状態のときに、大きく傾いた各スラットの空間部が、日射光を通そうとする。しかし、この発明では、空間部が上段又は下段のスラットの縁部と重なることで塞がれるよう構成される。この結果、スラットを全閉状態にすると、完全に遮光され、空間部を通じた漏光は生じない。 In order to solve the above-described problems, the present invention supports a plurality of ladder slats that are pulled out from a head box and connected to the bottom rail at the lower end so that a plurality of slats can be adjusted in angle, and pulled out from the head box. A horizontal blind capable of moving a slat up and down by a plurality of elevating tapes connected to the bottom rail at the lower end, wherein at least one space portion is provided on at least one edge of the slat, and the space portion is provided in each slat. It is configured so as to be closed by overlapping with the edge of the upper or lower slat when closed, and each lifting tape is inserted into each space. With this configuration, a plurality of slats can be moved up and down by the lifting tape. And the angle of a slat can be adjusted with a ladder code and a slat can be made into a fully closed state. In the fully closed state, the space portion of each slat that is greatly inclined tries to transmit sunlight. However, according to the present invention, the space portion is configured to be closed by overlapping with the edge portion of the upper or lower slat. As a result, when the slats are fully closed, they are completely shielded from light and no light leaks through the space.
　好ましくは、上記少なくとも一段のスラットの一方の縁部に設けられた空間部と他方の縁部に設けられた空間部とがスラットの長さ方向に当該空間部長さ以上にずれるように、複数の当該空間部を各スラットの幅方向の両縁部に配設した構成とする。この発明では、空間部が各スラットの幅方向の両縁部に配設されているので、上段のスラットの下縁部に設けられた空間部に、下段のスラットの上縁部が重なった状態になり、当該空間部が下段のスラットによって塞がれる。このとき、上段のスラットの下縁部の設けられた空間部と下段のスラットの上縁部に設けられた空間部とは、スラットの長さ方向に当該空間部長さ以上にずれているので、互いに重なることはない。この結果、スラットを全閉状態にすると、完全に遮光され、空間部を通じた漏光は生じない。また、複数の当該空間部を各スラットの幅方向の両縁部に配設すると共に、各昇降テープを各空間部内に挿通しているので、昇降テープが、ボトムレールの幅方向両側に接続した構造になっている。つまり、昇降テープがボトムレールの幅方向の一方側にのみ接続された構造の場合には、ボトムレールを上昇させる際に、ボトムレールの一方側のみが昇降テープによって引っ張られるため、ボトムレールが傾いて、スラット全体が反り返ってしまう。しかし、この発明では、昇降テープをボトムレールの幅方向両側に接続した構造になっているので、ボトムレールに対する引っ張り力のバランスがとれ、スラットが反り返ることはない。 Preferably, the space portion provided at one edge portion of the at least one slat and the space portion provided at the other edge portion are shifted in a length direction of the slat so as to be more than the space portion length. The said space part is set as the structure arrange | positioned in the both edges of the width direction of each slat. In this invention, since the space part is arrange | positioned at the both edges of the width direction of each slat, the upper edge part of the lower slat has overlapped with the space part provided in the lower edge part of the upper slat Thus, the space is closed by the lower slats. At this time, the space portion provided at the lower edge portion of the upper slat and the space portion provided at the upper edge portion of the lower slat are shifted beyond the space portion length in the length direction of the slat. They do not overlap each other. As a result, when the slats are fully closed, they are completely shielded from light and no light leaks through the space. Moreover, since the said several space part is arrange | positioned in the both edges of the width direction of each slat, and each raising / lowering tape is penetrated in each space part, the raising / lowering tape was connected to the width direction both sides of a bottom rail. It has a structure. In other words, when the lifting tape is connected only to one side in the width direction of the bottom rail, when raising the bottom rail, only the one side of the bottom rail is pulled by the lifting tape, so the bottom rail tilts. The entire slat will warp. However, according to the present invention, since the lifting tape is connected to both sides in the width direction of the bottom rail, the tensile force against the bottom rail is balanced, and the slat does not warp.
　好ましくは、空間部の全てが、閉空間を形成する挿通孔である構成とする。 Preferably, all the space portions are configured to be insertion holes that form a closed space.
好ましくは、空間部の一部が、開空間を形成する切り欠きであり、空間部の残りが、閉空間を形成する挿通孔である構成とする。 Preferably, a part of the space part is a notch that forms an open space, and the rest of the space part is an insertion hole that forms a closed space.
好ましくは、ヘッドボックス外部の操作コードにより長さ方向の中心軸周りに回転操作可能な１本の軸体が、ヘッドボックス内に設けられ、ラダーコードの上端部が固着された第１のドラムと、昇降テープの上端部が固着された第２のドラムとが、１本の軸体に同心状態で固着されている構成とした。かかる構成により、操作コードによって、１本の軸体を中心軸周りに回転操作すると、１本の軸体に固着された第２のドラムが回転して、昇降テープが第２のドラムに巻き取られ又は巻き戻される。そして、第１のドラムに上端部が固着されたラダーコードの動きによって、スラットが所定角度に傾く。したがって、この発明では、太さのある昇降コードの代わりに、薄い昇降テープを第２のドラムに巻き取ってスラットを上昇させることができるので、ヘッドボックスの大きさや巻取コーンのスペース確保等を考慮して設計する必要がない。このため、小型化で部品点数が少なく、しかも、ほぼ完全な遮光が可能な横型ブラインドを製造することができる。 Preferably, one shaft body that can be rotated around a central axis in the length direction by an operation cord outside the head box is provided in the head box, and the first drum to which the upper end portion of the ladder cord is fixed The second drum to which the upper end portion of the elevating tape is fixed is fixed to one shaft body in a concentric state. With this configuration, when one shaft body is rotated around the central axis by the operation cord, the second drum fixed to the one shaft body rotates, and the lifting tape is wound around the second drum. Or rewinded. Then, the slat is inclined at a predetermined angle by the movement of the ladder cord whose upper end is fixed to the first drum. Therefore, in the present invention, instead of a thick lifting cord, a thin lifting tape can be wound around the second drum to raise the slat, so that the size of the head box, the space for the winding cone, etc. can be secured. There is no need to design with consideration. For this reason, it is possible to manufacture a horizontal blind that is small in size, has a small number of parts, and can almost completely block light.
　好ましくは、昇降テープを、最上段のスラットから数えて所定枚数のスラットの空間部には挿通させず、当該非挿通スラットより下段のスラットの空間部に挿通させた構成とする。昇降テープを全てのスラットの空間部に挿通させておくと、スラットの全閉時には、上段のスラットに対して、幅方向の引っ張り力が働き、下段のスラットに対しては幅方向の引っ張り力は、ほとんど生じない。かかる状態では、上段のスラットの傾きが少なく、閉状態にならないおそれがある。したがって、この発明のように、昇降テープを、最上段のスラットから数えて所定枚数のスラットには挿通させない構成とすることで、全てのスラットを閉状態することができ、遮光性を更に高めることができる。 Preferably, the elevating tape is configured not to be inserted through the space portion of a predetermined number of slats counted from the uppermost slat, but to be inserted into the space portion of the lower slat from the non-insertion slat. If the lifting tape is inserted through the space of all the slats, when the slats are fully closed, the pulling force in the width direction acts on the upper slats, and the pulling force in the width direction acts on the lower slats. Seldom occurs. In such a state, the inclination of the upper slat is small, and there is a possibility that the closed state will not occur. Therefore, as in the present invention, the elevating tape is configured not to be inserted through a predetermined number of slats counted from the uppermost slat, so that all the slats can be closed and the light shielding property is further improved. Can do.
　好ましくは、昇降テープを、最下段のスラットから数えて所定枚数のスラットの空間部には、挿通させず、当該非挿通スラットより上段のスラットの空間部に挿通させた構成とする。かかる構成により、最下段付近のスラットに対する幅方向の引っ張り力の発生を防止して、最下段付近のスラットの閉状態を確保にする。 Preferably, the elevating tape is configured not to be inserted into the space portion of the predetermined number of slats counted from the lowermost slat, but to be inserted into the space portion of the upper slat from the non-insertion slat. With this configuration, the generation of a tensile force in the width direction on the slats near the lowermost stage is prevented, and the closed state of the slats near the lowermost stage is ensured.
　好ましくは、上記空間部が挿通孔であり、当該挿通孔を、上記少なくとも一段のスラットの幅方向に位置する縁部であって且つスラットの閉時に上方に位置する縁部に、スラット長さ方向に沿って設け、各昇降テープを、挿通孔に挿通した構成とする。かかる構成により、スラットの閉時には、スラットの上方に位置する縁部が、挿通孔に挿通された昇降テープによって支持されたような状態になる。このため、閉時には、全てのスラットが、相対的に、上方の縁部を中心に下方に回転したような状態になるので、スラットがほぼ垂直な状態に傾いて閉じるため、遮光性を更に高めることができる。 Preferably, the space portion is an insertion hole, and the insertion hole is an edge portion positioned in the width direction of the at least one slat, and an edge portion positioned upward when the slat is closed, in the slat length direction. And each elevating tape is configured to be inserted through the insertion hole. With such a configuration, when the slat is closed, the edge located above the slat is in a state of being supported by the lifting tape inserted through the insertion hole. For this reason, when closed, all the slats are relatively rotated downward about the upper edge, so that the slats are tilted and closed in a substantially vertical state, thus further improving the light shielding performance. be able to.
　好ましくは、挿通孔を、複数設けた構成とする。 Preferably, a plurality of insertion holes are provided.
　以上詳しく説明したように、この発明の横型ブラインドによれば、昇降テープを、太さのある昇降コードの代わりに用い、しかも、昇降テープを挿通させる空間部を、スラットの中心から縁部側に偏心させた構成になっているので、昇降テープによる製品の小型化や部品点数の削減を図ることができると共に、空間部の偏心による遮光性を向上させるという優れた効果がある。 As described above in detail, according to the horizontal blind of the present invention, the lifting tape is used in place of a thick lifting cord, and the space through which the lifting tape is inserted extends from the center of the slat to the edge side. Since it has an eccentric configuration, it is possible to reduce the size of the product and reduce the number of parts by using the lifting tape, and there is an excellent effect of improving the light shielding property due to the eccentricity of the space portion.

Specifically, as shown in FIGS. 5 and 6, the end of the weft thread 43 side of the ladder cords 4A to 4D is positioned below the end of the weft thread 44 on the warp thread 41 side. , Connected to the warp 41. The end of the weft thread 43 on the warp thread 42 side is connected to the warp thread 42 so as to be positioned above the end of the weft thread 44 on the warp thread 42 side. The slat 3 is inserted between the wefts 43 and 44 and is sandwiched from above and below by the wefts 43 and 44.
　上記のようにラダーコード４Ａ～４Ｄに支持されるスラット３は、図７に示すように、４つの空間部３１～３４を有している。各空間部３１（３２～３４）は、平面視において閉じており、閉空間を形成する長方形の挿通孔である。各挿通孔３１（３２～３４）の長さａは、昇降テープ５Ａ（５Ｂ～５Ｄ）の幅よりも若干大きめに設定され、幅ｂは、昇降テープ５Ａ（５Ｂ～５Ｄ）の厚さよりも大きめに設定されている。挿通孔３１～３４のうち、２つの挿通孔３１，３２は、室外側の縁部３ａ（一方の縁部）の長さ方向両端部であって且つラダーコード４Ａ，４Ｂ（図５参照）の近傍にそれぞれ配設されている。残りの挿通孔３３，３４は、室内側の縁部３ｂ（他方の縁部）の中央部分の２カ所であって且つラダーコード４Ｃ，４Ｄ（図５参照）の近傍にそれぞれ配設されている。さらに、挿通孔３１，３２と挿通孔３３，３４との位置関係は、後述する遮光性の観点から、挿通孔３１，３２と挿通孔３３，３４とが対向しないように、設定されている。具体的には、挿通孔３１（３２）と挿通孔３３（３４）との長さ方向のずれ量δを、挿通孔３１（３２～３４）の長さａ以上に設定した。昇降テープ５Ａ～５Ｄは、このような挿通孔３１～３４にそれぞれ挿通されている。具体的には、図５に示すように、昇降テープ５Ａ～５Ｄを、ラダーコード４Ａ～４Ｄにそれぞれ沿った状態で、ヘッドボックス２から垂下させ、図６の（ａ）に示すように、昇降テープ５Ａ（５Ｂ）を挿通孔３１（３２）に挿通させ、図６の（ｂ）に示すように、昇降テープ５Ｃ（５Ｄ）を挿通孔３３（３４）にそれぞれ挿通した。 As described above, the slat 3 supported by the ladder cords 4A to 4D has four space portions 31 to 34 as shown in FIG. Each space portion 31 (32 to 34) is a rectangular insertion hole that is closed in a plan view and forms a closed space. The length a of each insertion hole 31 (32 to 34) is set slightly larger than the width of the elevating tape 5A (5B to 5D), and the width b is larger than the thickness of the elevating tape 5A (5B to 5D). Is set to Of the insertion holes 31 to 34, the two insertion holes 31 and 32 are both ends in the longitudinal direction of the edge 3a (one edge) on the outdoor side, and the ladder cords 4A and 4B (see FIG. 5). Each is arranged in the vicinity. The remaining insertion holes 33 and 34 are disposed at two locations in the center of the indoor side edge 3b (the other edge) and in the vicinity of the ladder cords 4C and 4D (see FIG. 5). . Furthermore, the positional relationship between the insertion holes 31 and 32 and the insertion holes 33 and 34 is set so that the insertion holes 31 and 32 and the insertion holes 33 and 34 do not face each other from the viewpoint of light shielding properties described later. Specifically, the displacement δ in the length direction between the insertion hole 31 (32) and the insertion hole 33 (34) is set to be equal to or longer than the length a of the insertion hole 31 (32 to 34). The elevating tapes 5A to 5D are inserted through the insertion holes 31 to 34, respectively. Specifically, as shown in FIG. 5, elevating tapes 5A to 5D are suspended from the head box 2 along the ladder cords 4A to 4D, and as shown in FIG. The tape 5A (5B) was inserted into the insertion hole 31 (32), and the lifting tape 5C (5D) was inserted into the insertion hole 33 (34) as shown in FIG. 6B.
　次に、この実施例の横型ブラインドが示す作用及び効果について説明する。図１において、操作コード７０を操作し、操作機構７のプーリーを回転させると、その回転が、ギアボックス７１を介して角軸６０に伝達される。したがって、角軸６０の回転によって、ドラム機構６Ａ～６Ｄの巻取りドラム６２が回転すると、昇降テープ５Ａ～５Ｄが、巻取りドラム６２に巻き取られ、あるいは巻戻される。そして、昇降テープ５Ａ～５Ｄが巻取りドラム６２に巻き取られると、ボトムレール２０及びスラット３が引き上げられ、昇降テープ５Ａ～５Ｄが巻取りドラム６２から巻き戻されると、ボトムレール２０及びスラット３が下降する。また、操作コード７０の操作によって、ドラム機構６Ａ～６Ｄの角軸６０が回転されると、吊下げドラム６１が一体に回転して、ラダーコード４Ａ～４Ｄを介してスラット３が回転される。そして、スラット３が垂直方向まで回転されると、吊下げドラム６１が、金属リング６１ａ（図２参照）に対し空回りして、スラット３の同方向へのそれ以上の回転が阻止されるようになっている。なお、スラット３が、所望高さまで引き上げられ、あるいは下降された後、操作コード７０を逆方向に操作して角軸６０を逆方向に回転させれば、吊下げドラム６１が回転されて、スラット３が所望角度に傾く。このように、この実施例の横型ブラインド１－１によれば、太さのある昇降コードの代わりに、薄い昇降テープ５Ａ～５Ｄを巻取りドラム６２に巻き取ってスラット３とボトムレール２０とを上昇させる構成としたので、ヘッドボックス２の大きさや巻取コーンのスペース確保等を考慮することなく設計することができ、この結果、ヘッドボックス２の小型化と部品点数の削減を図ることができる。 Next, the operation and effect of the horizontal blind according to this embodiment will be described. In FIG. 1, when the operation cord 70 is operated to rotate the pulley of the operation mechanism 7, the rotation is transmitted to the angular shaft 60 via the gear box 71. Therefore, when the take-up drum 62 of the drum mechanisms 6A to 6D is rotated by the rotation of the square shaft 60, the elevating tapes 5A to 5D are taken up or rewound on the take-up drum 62. When the lifting tapes 5A to 5D are wound around the winding drum 62, the bottom rail 20 and the slat 3 are pulled up, and when the lifting tapes 5A to 5D are rewound from the winding drum 62, the bottom rail 20 and the slats 3 are pulled up. Descends. Further, when the angular shaft 60 of the drum mechanisms 6A to 6D is rotated by the operation of the operation cord 70, the suspension drum 61 is rotated integrally and the slat 3 is rotated via the ladder cords 4A to 4D. When the slat 3 is rotated to the vertical direction, the suspension drum 61 is idled with respect to the metal ring 61a (see FIG. 2) so that the slat 3 is prevented from further rotation in the same direction. It has become. When the slat 3 is pulled up or lowered to a desired height and then the operation cord 70 is operated in the reverse direction to rotate the angular shaft 60 in the reverse direction, the suspension drum 61 is rotated and the slats are rotated. 3 tilts to the desired angle. Thus, according to the horizontal blind 1-1 of this embodiment, instead of the thick lifting / lowering cord, thin lifting / lowering tapes 5A to 5D are wound around the winding drum 62 so that the slat 3 and the bottom rail 20 are connected. Since it is configured to be raised, it can be designed without considering the size of the head box 2 and the space for the winding cone, etc. As a result, the head box 2 can be reduced in size and the number of parts can be reduced. .
　図８は、全閉状態を示す横型ブラインドの概略断面図であり、図９は、室外側から見た全閉状態の横型ブラインドを示す概略裏面図である。なお、図８においては、理解を容易にするため、２つの挿通孔３１（３２）と挿通孔３３（３４）とを１枚のスラット３の断面に明示すると共に、ラダーコード４Ａ～４Ｄの記載を省略した。上記のごとく、操作コード７０を操作することで、スラット３とボトムレール２０とを最下段まで下降させて、図８及び図９に示すように、スラット３を全閉状態にすることができる。かかる状態では、室外の日射光Ｌがスラット３側に向かい、挿通孔３１～３４を通過して、室内に入り込もうとする。 FIG. 8 is a schematic cross-sectional view of the horizontal blind showing the fully closed state, and FIG. 9 is a schematic back view showing the horizontal blind in the fully closed state as seen from the outdoor side. In FIG. 8, for easy understanding, the two insertion holes 31 (32) and the insertion holes 33 (34) are clearly shown in the cross section of one slat 3, and the ladder codes 4A to 4D are shown. Was omitted. As described above, by operating the operation cord 70, the slat 3 and the bottom rail 20 can be lowered to the lowest level, and the slat 3 can be fully closed as shown in FIGS. In such a state, the outdoor sunlight L is directed to the slat 3 side, passes through the insertion holes 31 to 34, and tries to enter the room.
　図１０は、横型ブラインド１－１の作用及び効果を説明するための断面図である。この実施例の横型ブラインド１－１では、図７で示したように、挿通孔３１～３４をスラット３の幅方向に分散し、しかも、各挿通孔３１～３４を長さ方向にずらした構成になっている。したがって、全閉状態では、図９及び図１０の（ａ）に示すように、上段スラット３ー１の下縁部３ａが、下段スラット３ー２の上縁部３ｂに設けられた挿通孔３３（３４）に重なった状態になっている。このため、室外側から下段スラット３－２の挿通孔３３（３４）に向かう日射光Ｌは、上段スラット３ー１の下縁部３ａによって遮られるので、日射光Ｌが、挿通孔３３（３４）を通過して室内に進入することはない。また、図１０の（ｂ）に示すように、日射光Ｌは、上段スラット３ー１の下縁部３ａに設けられた挿通孔３１（３２）を通過する。しかし、下段スラット３ー２の上縁部３ｂが挿通孔３１（３２）の背後に重なった状態になっている。このため、上段スラット３－１の挿通孔３１（３２）を通過した日射光Ｌは、下段スラット３ー２の上縁部３ｂによって遮られるので、日射光Ｌが室内に進入することはない。このように、この実施例の横型ブラインド１－１によれば、スラットを全閉状態にした際の、挿通孔３１～３４による漏光を、ほぼ完全に防止することができる。 FIG. 10 is a cross-sectional view for explaining the operation and effect of the horizontal blind 1-1. In the horizontal blind 1-1 of this embodiment, as shown in FIG. 7, the insertion holes 31 to 34 are dispersed in the width direction of the slat 3, and the insertion holes 31 to 34 are shifted in the length direction. It has become. Therefore, in the fully closed state, as shown in FIGS. 9 and 10A, the lower edge 3a of the upper slat 3-1 is inserted into the insertion hole 33 provided in the upper edge 3b of the lower slat 3-2. (34) is overlapped. For this reason, the sunlight L directed from the outdoor side toward the insertion hole 33 (34) of the lower slat 3-2 is blocked by the lower edge 3a of the upper slat 3-1, so that the sunlight L is inserted into the insertion hole 33 (34). ) Will not enter the room. Further, as shown in FIG. 10B, the sunlight L passes through the insertion hole 31 (32) provided in the lower edge portion 3a of the upper slat 3-1. However, the upper edge 3b of the lower slat 3-2 overlaps the back of the insertion hole 31 (32). For this reason, the solar radiation L that has passed through the insertion hole 31 (32) of the upper slat 3-1 is blocked by the upper edge 3b of the lower slat 3-2, so that the solar light L does not enter the room. As described above, according to the horizontal blind 1-1 of this embodiment, it is possible to almost completely prevent light leakage through the insertion holes 31 to 34 when the slat is fully closed.
　また、図１において、もし、ボトムレール２０を室外側の昇降テープ５Ａ，５Ｂのみで支持し、昇降テープ５Ｃ，５Ｄで支持しない場合には、上昇時に、ボトムレール２０が昇降テープ５Ａ，５Ｂの接続点を中心に回転し、傾いてしまう。このため、スラット３全体が反り返ってしまう。しかし、この実施例では、ボトムレール２０の室外側縁部を、昇降テープ５Ａ，５Ｂで支持し、ボトムレール２０の室内側縁部を、昇降テープ５Ｃ，５Ｄで支持しているので、ボトムレール２０が傾いてスラット３全体が反り返るおそれはない。 In FIG. 1, if the bottom rail 20 is supported only by the outdoor lifting tapes 5A and 5B and not supported by the lifting tapes 5C and 5D, the bottom rail 20 is lifted from the lifting tapes 5A and 5B. Rotates around the connection point and tilts. For this reason, the entire slat 3 is warped. However, in this embodiment, the outdoor edge of the bottom rail 20 is supported by the lifting tapes 5A and 5B, and the indoor side edge of the bottom rail 20 is supported by the lifting tapes 5C and 5D. There is no possibility that the entire slat 3 is warped by tilting 20.
　さらに、この実施例では、図５に示すように、昇降テープ５Ａ～５Ｄを、ラダーコード４Ａ～４Ｄにそれぞれ沿った状態でヘッドボックス２から垂下させている。つまり、昇降テープ５Ａ（５Ｂ～５Ｄ）を、ラダーコード４Ａ（４Ｂ～４Ｄ）の縦糸４１に近接させている。これにより、昇降テープ５Ａ（５Ｂ～５Ｄ）が昇降時にスラット３の長さ方向に横揺れした場合でも、横揺れするや否や、昇降テープ５Ａ（５Ｂ～５Ｄ）がラダーコード４Ａ（４Ｂ～４Ｄ）の横糸４３，４４に引っ掛かって移動が阻止される。この結果、昇降テープ５Ａ～５Ｄの横揺れによるスラット３の横ずれは生じない。 Furthermore, in this embodiment, as shown in FIG. 5, the elevating tapes 5A to 5D are suspended from the head box 2 along the ladder cords 4A to 4D, respectively. That is, the lifting tape 5A (5B to 5D) is brought close to the warp thread 41 of the ladder cord 4A (4B to 4D). As a result, even when the lifting tape 5A (5B to 5D) rolls in the length direction of the slat 3 during lifting, as soon as the lifting tape 5A (5B to 5D) rolls, the ladder tape 4A (4B to 4D) Are caught by the weft threads 43 and 44 and are prevented from moving. As a result, the lateral displacement of the slat 3 due to the rolling of the lifting tapes 5A to 5D does not occur.
　ところで、図１において、操作コード７０を操作し、巻取りドラム６２を回転させると、吊下げドラム６１も巻取りドラム６２と一体に回転するが、下降時には、昇降テープ５Ａ～５Ｄにのみボトムレール２０による張力が加わり、ラダーコード４Ａ～４Ｄには加わらない。しかし、ボトムレール２０が最下点まで下がり、ラダーコード４Ａ～４Ｄが延びきると、ボトムレール２０による張力がラダーコード４Ａ～４Ｄに移ることとなる。このとき、ラダーコード４Ａ～４Ｄの吊下げドラム６１は回転した状態にあるので、ラダーコード４Ａ～４Ｄがスラット３を全閉方向に傾斜させるだけでなく、ボトムレール２０をも傾斜させる。したがって、ボトムレール２０を最下位迄下降させ、スラット３を全閉にした状態で、ボトムレール２０をほぼ水平にするには、最下位で、ボトムレール２０による張力がラダーコード４Ａ～４Ｄに加わらないように設定する必要がある。その一例として次のような設定が可能である。ボトムレール２０が最下位にあるときの昇降テープ５Ａ，５Ｂの長さと昇降テープ５Ｃ，５Ｄの長さが等しくなるように設定する。さらに、かかる最下位において、ラダーコード４Ａ～４Ｄの長さが昇降テープ５Ａ～５Ｄよりも長くなるように、ラダーコード４Ａ～４Ｄの長さを設定する。これにより、ボトムレール２０が下降し、最下位に達すると、ラダーコード４Ａ～４Ｄが余って弛んだ状態になり、昇降テープ５Ａ～５Ｄでのみ、ボトムレール２０を水平に支持することとなる。このように、ボトムレール２０を最下点で水平に支持することで、少なくとも最下段のスラット３が水平なボトムレール２０の上面に確実に接触して、高度な遮光性を実現する。また、ボトムレール２０を水平に保つことで、スラット３がボトムレール２０によって支えられるので、スラット３の落ち込みを防止することができる。 Incidentally, in FIG. 1, when the operation cord 70 is operated to rotate the winding drum 62, the suspension drum 61 also rotates together with the winding drum 62. However, when it is lowered, only the lifting tape 5A to 5D has a bottom rail. No. 20 is applied to the ladder cords 4A to 4D. However, when the bottom rail 20 is lowered to the lowest point and the ladder cords 4A to 4D are fully extended, the tension due to the bottom rail 20 is transferred to the ladder cords 4A to 4D. At this time, since the suspension drum 61 of the ladder cords 4A to 4D is in a rotated state, the ladder cords 4A to 4D not only incline the slats 3 in the fully closed direction but also incline the bottom rail 20. Therefore, in order to make the bottom rail 20 almost horizontal with the bottom rail 20 lowered to the lowest position and the slat 3 fully closed, the tension by the bottom rail 20 is applied to the ladder cords 4A to 4D at the lowest position. It is necessary to set not to. As an example, the following settings are possible. The length of the elevating tapes 5A and 5B when the bottom rail 20 is at the lowest position is set so that the lengths of the elevating tapes 5C and 5D are equal. Further, the length of the ladder cords 4A to 4D is set so that the length of the ladder cords 4A to 4D is longer than that of the elevating tapes 5A to 5D at the lowest position. As a result, when the bottom rail 20 descends and reaches the lowest position, the ladder cords 4A to 4D are loosened excessively, and the bottom rail 20 is supported horizontally only by the lifting tapes 5A to 5D. In this way, by supporting the bottom rail 20 horizontally at the lowest point, at least the lowermost slat 3 reliably contacts the upper surface of the horizontal bottom rail 20 and realizes a high light shielding property. Moreover, since the slat 3 is supported by the bottom rail 20 by keeping the bottom rail 20 horizontal, the slat 3 can be prevented from falling.
（実施例２）
　次に、この発明の第２実施例について説明する。図１１は、この発明の第２実施例に係る横型ブラインドを示す斜視図であり、図１２は、この実施例の要部を示すスラットの平面図である。図１１に示すように、この実施例の横型ブラインド１－２では、昇降テープを通す挿通孔をスラットの室内側の縁部にのみ設けた点が、上記第１の実施例と異なる。すなわち、この実施例の横型ブラインド１－２も、上記第１実施例の横型ブラインド１－１と同様に、スラット３を支持したラダーコード４Ａ～４Ｄと昇降テープ５Ａ～５Ｄとが、ヘッドボックス２内のドラム機構６Ａ～６Ｄから吊り下げられており、操作機構７の操作コード７０によって、これらの昇降テープ５Ａ～５Ｄ及びラダーコード４Ａ～４Ｄを昇降及び回転させることで、スラット３の昇降及び回転させることができるようになっている。 (Example 2)
Next explained is the second embodiment of the invention. FIG. 11 is a perspective view showing a horizontal blind according to a second embodiment of the present invention, and FIG. 12 is a plan view of a slat showing a main part of this embodiment. As shown in FIG. 11, the horizontal blind 1-2 of this embodiment is different from the first embodiment in that an insertion hole through which the lifting tape is passed is provided only at the indoor side edge of the slat. That is, in the horizontal blind 1-2 of this embodiment, as with the horizontal blind 1-1 of the first embodiment, the ladder cords 4A to 4D supporting the slats 3 and the lifting tapes 5A to 5D are connected to the head box 2. The lifting and lowering tapes 5A to 5D and the ladder cords 4A to 4D are moved up and down and rotated by the operation cord 70 of the operation mechanism 7 so that the slats 3 are moved up and down and rotated. It can be made to.
　しかし、この実施例の横型ブラインド１－２では、図１２に示すように、２つの挿通孔３３，３４のみが、スラット３に設けられている。具体的には、２つの挿通孔３３，３４を、スラット３の閉時に上方に位置する室内側の縁部３ｂの中央部分の２カ所に設け、室外側の縁部３ａには、挿通孔を設けていない。このため、図１１に示すように、昇降テープ５Ｃ，５Ｄは、挿通孔３３，３４に挿通された状態で、ラダーコード４Ｃ，４Ｄに沿って吊り下がり、昇降テープ５Ａ，５Ｂは、スラット３の縁部３ａの外に位置した状態で、ラダーコード４Ａ，４Ｂに沿って吊り下がる。 However, in the horizontal blind 1-2 of this embodiment, only two insertion holes 33 and 34 are provided in the slat 3 as shown in FIG. Specifically, the two insertion holes 33 and 34 are provided at two locations in the central portion of the indoor side edge 3b located above when the slat 3 is closed, and the insertion holes are provided in the outdoor edge 3a. Not provided. For this reason, as shown in FIG. 11, the elevating tapes 5C and 5D are suspended along the ladder cords 4C and 4D while being inserted through the insertion holes 33 and 34, and the elevating tapes 5A and 5B are It hangs along the ladder cords 4A and 4B while being positioned outside the edge 3a.
　次に、この実施例の横型ブラインド１－２が示す作用及び効果について説明する。図１３は、この実施例の作用及び効果を説明するための断面図である。上記第１実施例の横型ブラインド１－１では、図１に示したように、昇降テープ５Ａ，５Ｂがスラット３の挿通孔３１，３２に挿通され、昇降テープ５Ｃ，５Ｄが挿通孔３３，３４に挿通された構成である。このため、スラット３の全閉時には、図１３の二点鎖線で示すように、スラット３の下縁部３ａが、挿通孔３１（３２）に挿通された昇降テープ５Ａ（５Ｂ）によって引っ張られ、大きな隙間Ｇが、上段のスラット３と下段のスラット３との間に発生するおそれがある。これに対して、この実施例の横型ブラインド１－２では、昇降テープ５Ｃ（５Ｄ）のみが室内側の挿通孔３３（３４）に挿通された構成になっている。このため、スラット３の全閉時に、スラット３の下縁部３ａに対する昇降テープ５Ａ（５Ｂ）による引張力は働かず、スラット３の上縁部３ｂが、挿通孔３３（３４）に挿通された昇降テープ５Ｃ（５Ｄ）によって支持されたような状態になる。この結果、実線で示すように、スラット３が、相対的に、上縁部３ｂを中心に下方に回転したような状態になる。これにより、上段のスラット３と下段のスラット３との間の隙間Ｇが非常に小さくなり、ブラインドの遮光性がさらに高くなる。その他の構成，作用及び効果は上記第１実施例と同様であるので、その記載は省略する。 Next, functions and effects of the horizontal blind 1-2 according to this embodiment will be described. FIG. 13 is a cross-sectional view for explaining the operation and effect of this embodiment. In the horizontal blind 1-1 of the first embodiment, as shown in FIG. 1, the elevating tapes 5A and 5B are inserted into the insertion holes 31 and 32 of the slat 3, and the elevating tapes 5C and 5D are inserted into the insertion holes 33 and 34, respectively. It is the structure inserted in. Therefore, when the slat 3 is fully closed, the lower edge 3a of the slat 3 is pulled by the lifting tape 5A (5B) inserted through the insertion hole 31 (32), as shown by a two-dot chain line in FIG. A large gap G may be generated between the upper slat 3 and the lower slat 3. On the other hand, in the horizontal blind 1-2 of this embodiment, only the elevating tape 5C (5D) is inserted into the indoor insertion hole 33 (34). For this reason, when the slat 3 is fully closed, the tensile force by the elevating tape 5A (5B) against the lower edge 3a of the slat 3 does not work, and the upper edge 3b of the slat 3 is inserted through the insertion hole 33 (34). It will be in the state supported by the raising / lowering tape 5C (5D). As a result, as shown by the solid line, the slat 3 is relatively rotated downward about the upper edge 3b. As a result, the gap G between the upper slat 3 and the lower slat 3 becomes very small, and the light shielding property of the blind is further enhanced. Since other configurations, operations, and effects are the same as those of the first embodiment, description thereof is omitted.
（実施例３）
　次に、この発明の第３実施例について説明する。図１４は、この発明の第３実施例に係る横型ブラインドを示す概略断面図である。なお、図１４においては、理解を容易にするため、２つ挿通孔３１（３２）と挿通孔３３（３４）とを１枚のスラット３の断面に明示すると共に、ラダーコード４Ａ～４Ｄの記載を省略した。上記第１実施例では、図１に示したように、昇降テープ５Ａ（５Ｂ）と昇降テープ５Ｃ（５Ｄ）を、上段のスラット３から下段のスラット３に渡って、全てのスラット３の挿通孔３１（３２）と挿通孔３３，３４とにそれぞれ挿通させていた。このため、スラット３の閉時に、昇降テープ５Ａ（５Ｂ）がスラット３を図１４の左方向に引っ張り、昇降テープ５Ｃ（５Ｄ）がスラット３を右方向に引っ張る現象が生じる。この引っ張り力は、下段のスラット３に対してはほとんど生じないが、上段から数えて１枚～６枚程のスラット３には、ヘッドボックス２からの昇降テープ５Ａ～５Ｄの前後垂下幅の影響によって、引っ張り力が働く。このため、図１４の二点鎖線で示すように、１枚～６枚のスラット３－１～３－６の傾きが制限され、これらのスラット３－１～３－６間の遮光性が損なわれるおそれがある。そこで、この実施例では、図１４の実線で示すように、昇降テープ５Ａ～５Ｄを、上段のスラット３－１～３－６には挿通させず、下段のスラット３－７以降のスラットについて、挿通させる構成とした。具体的には、昇降テープ５Ａ（５Ｂ）と昇降テープ５Ｃ（５Ｄ）を、スラット３－１～から３－６の挿通孔３１（３２）と挿通孔３３，３４とには挿通させない。これに対して、下段のスラット３－７～３－ｎー１（ｎは８以上の整数）の挿通孔３１（３２）と挿通孔３３，３４とには、昇降テープ５Ａ（５Ｂ）と昇降テープ５Ｃ（５Ｄ）を挿通させる。また、最下段のスラット３－ｎについては、昇降テープ５Ａ～５Ｄを挿通させない。これは、昇降テープ５Ａ～５Ｄの下端部が、ボトムレール２０に接続されため、ボトムレール２０近傍のスラット３－ｎに対して、昇降テープ５Ａ～５Ｄによる図１４左右方向の大きな引っ張り力が働くからである。 Example 3
Next explained is the third embodiment of the invention. FIG. 14 is a schematic sectional view showing a horizontal blind according to a third embodiment of the present invention. In FIG. 14, for easy understanding, the two insertion holes 31 (32) and the insertion holes 33 (34) are clearly shown on the cross section of one slat 3, and the ladder codes 4A to 4D are shown. Was omitted. In the first embodiment, as shown in FIG. 1, the elevating tape 5A (5B) and the elevating tape 5C (5D) are inserted from the upper slat 3 to the lower slat 3 so that all the slats 3 are inserted. 31 (32) and the insertion holes 33 and 34, respectively. Therefore, when the slat 3 is closed, the lifting tape 5A (5B) pulls the slat 3 leftward in FIG. 14, and the lifting tape 5C (5D) pulls the slat 3 rightward. This pulling force hardly occurs for the lower slats 3, but the influence of the front and rear hanging widths of the lifting tapes 5A to 5D from the head box 2 on the 1 to 6 slats 3 counted from the upper stage. Due to this, the pulling force works. For this reason, as shown by the two-dot chain line in FIG. 14, the inclination of one to six slats 3-1 to 3-6 is limited, and the light shielding property between these slats 3-1 to 3-6 is impaired. There is a risk of being. Therefore, in this embodiment, as shown by the solid line in FIG. 14, the elevating tapes 5A to 5D are not inserted into the upper slats 3-1 to 3-6, and the slats after the lower slats 3-7 are as follows. It was set as the structure penetrated. Specifically, the elevating tape 5A (5B) and the elevating tape 5C (5D) are not inserted into the insertion holes 31 (32) and the insertion holes 33 and 34 of the slats 3-1 to 3-6. On the other hand, the lower slats 3-7 to 3-n-1 (n is an integer of 8 or more) are inserted into the insertion holes 31 (32) and the insertion holes 33 and 34, and the elevation tape 5A (5B) The tape 5C (5D) is inserted. Further, the elevating tapes 5A to 5D are not inserted into the lowermost slats 3-n. This is because the lower ends of the lifting tapes 5A to 5D are connected to the bottom rail 20, so that a large pulling force in the left-right direction in FIG. 14 by the lifting tapes 5A to 5D acts on the slats 3-n near the bottom rail 20. Because.
　かかる構成により、図１４の実線で示すように、スラットを下降させて全閉状態にすると、上段から下段に渡る全てのスラット３－１～３－ｎが、所望の角度で傾斜し、上段から下段に渡ってほぼ完全な遮光性を実現する。その他の構成，作用及び効果は上記第１及び第２実施例と同様であるので、その記載は省略する。 With this configuration, as shown by the solid line in FIG. 14, when the slat is lowered to the fully closed state, all the slats 3-1 to 3-n extending from the upper stage to the lower stage are inclined at a desired angle, Nearly complete light shielding is achieved across the bottom. Since other configurations, operations, and effects are the same as those of the first and second embodiments, description thereof is omitted.

　なお、この発明は、上記実施例に限定されるものではなく、発明の要旨の範囲内において種々の変形や変更が可能である。例えば、上記実施例では、この発明を一軸巻き取り式の横型ブラインドに適用した例を示したが、ラダーコードと昇降テープとを独立に操作可能な横型ブラインドにも適用することができることは勿論である。 The present invention is not limited to the above-described embodiments, and various modifications and changes can be made within the scope of the gist of the invention. For example, in the above-described embodiment, an example in which the present invention is applied to a uniaxial winding type horizontal blind has been described. However, it is needless to say that the present invention can also be applied to a horizontal blind in which a ladder cord and a lifting tape can be operated independently. is there.
　また、上記第３実施例では、最上段から６枚のスラット３－１～３－６について、昇降テープ５Ａ～５Ｄを非挿通としたが、非挿通のスラット枚数は、１枚～６枚の範囲内であればよく、昇降テープ５Ａ～５Ｄに加わる張力に応じて決定することができる。同様に、最上段から１枚のスラット３－ｎについて、昇降テープ５Ａ～５Ｄを非挿通としたが、その枚数も、ボトムレール２０近傍の昇降テープ５Ａ～５Ｄに加わる張力等によって決定することができる。 In the third embodiment, the elevating tapes 5A to 5D are not inserted into the six slats 3-1 to 3-6 from the top, but the number of non-inserted slats is 1 to 6. It may be within the range, and can be determined according to the tension applied to the elevating tapes 5A to 5D. Similarly, the lifting tapes 5A to 5D are not inserted into one slat 3-n from the top, but the number of the slats 3n can be determined by the tension applied to the lifting tapes 5A to 5D in the vicinity of the bottom rail 20. it can.
　さらに、図１９の実線で示すように、昇降テープ５Ａ（５Ｂ）や昇降テープ５Ｃ（５Ｄ）を、ボトムレール２０の側面２０ａや側面２０ｂに連結していると、スラット３の下降時に、昇降テープ５Ａ（５Ｂ）や昇降テープ５Ｃ（５Ｄ）がスラット３をボトムレール２０の外側側に引っ張って、遮光性を劣化させる可能性がある。このため、上記第３実施例では、昇降テープ５Ａ～５Ｄを、最下段のスラット３には挿通しなかった。しかし、図１９の二点鎖線で示すように、昇降テープ５Ａ（５Ｂ）や昇降テープ５Ｃ（５Ｄ）をボトムレール２０の中心側に接続した場合には、スラット３に対する引っ張り力はボトムレール２０の中心側に働く。したがって、このような場合には、昇降テープ５Ａ，５Ｂを、最下段のスラット３やその近くのスラット３の挿通孔３１～３４に挿通させても、遮光性劣化の問題は生じない。 Furthermore, as shown by the solid line in FIG. 19, when the lifting tape 5A (5B) or the lifting tape 5C (5D) is connected to the side surface 20a or the side surface 20b of the bottom rail 20, the lifting tape is lowered when the slat 3 is lowered. There is a possibility that 5A (5B) or the lifting tape 5C (5D) pulls the slats 3 to the outer side of the bottom rail 20 to deteriorate the light shielding property. For this reason, in the third embodiment, the elevating tapes 5A to 5D were not inserted into the lowermost slat 3. However, when the lifting tape 5A (5B) and the lifting tape 5C (5D) are connected to the center side of the bottom rail 20 as shown by a two-dot chain line in FIG. Work on the center side. Therefore, in such a case, even if the elevating tapes 5A and 5B are inserted through the insertion holes 31 to 34 of the lowermost slat 3 or the slats 3 near the lower slat 3, there is no problem of deterioration of light shielding performance.
