 まず、図1及び図2を参照して、本発明による一実施形態の横型ブラインドについて説明する。図1は、本発明による一実施形態の横型ブラインドの概略構成を示す斜視図である。また、図2は、本発明による一実施形態の横型ブラインドにおけるスラット4の平面図である。 First, a horizontal blind according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. 1 is a perspective view showing a schematic configuration of a horizontal blind according to an embodiment of the present invention. FIG. 2 is a plan view of the slat 4 in the horizontal blind according to the embodiment of the present invention.
 図1に示すように、本実施形態の横型ブラインドは、ヘッドボックス1の長手方向における左端部側、中央部側、及び右端部側からそれぞれ吊下されるラダーコード7L,7M,7Rを介して多数段のスラット4が支持される。各ラダーコード7L,7M,7Rの下端にボトムレール8が吊下支持されている。また、室外側又は室内側のラダーコード7L,7M,7Rに併設して複数の昇降コード6L,6M,6Rがヘッドボックス1から垂下され、その昇降コード6L,6M,6Rの下端にボトムレール8が取着されている。 As shown in FIG. 1, the horizontal blind according to the present embodiment is provided with ladder cords 7L, 7M, and 7R suspended from the left end side, the center side, and the right end side in the longitudinal direction of the head box 1, respectively. Multiple slats 4 are supported. A bottom rail 8 is suspended and supported at the lower ends of the ladder cords 7L, 7M, and 7R. In addition, a plurality of elevating cords 6L, 6M, 6R are suspended from the head box 1 alongside the outdoor or indoor ladder cords 7L, 7M, 7R, and a bottom rail 8 is provided at the lower ends of the elevating cords 6L, 6M, 6R. Is attached.
 多数段のスラット4の角度を調整する機構や、数段のスラット4を昇降させる機構、並びに、これらの機構を操作する操作手段は様々な既知の形態で実現することができ、これらの機構は、本発明の主旨とは直接的には関係しないことから、その一例を簡潔に説明する。 A mechanism for adjusting the angle of the multi-stage slats 4, a mechanism for moving the slats 4 up and down, and an operation means for operating these mechanisms can be realized in various known forms. Since it is not directly related to the gist of the present invention, an example thereof will be briefly described.
 ヘッドボックス1内にはラダーコード7L,7M,7R及び昇降コード6L,6M,6Rを吊下支持する支持部材10L,10M,10Rが配設され、この支持部材10L,10M,10Rには四角棒状の駆動軸12が挿通されている(後述する図4及び図5参照)。このような支持部材10L,10M,10Rにはチルトドラム(図示せず)が回転可能に支持され、このチルトドラムに当該駆動軸が相対回転不能に挿通されている。したがって、この駆動軸12が回転されると、当該チルトドラムが回転し、ラダーコード7L,7M,7Rにより吊下支持された多数段のスラット4の角度が調整されるようになっている。 In the head box 1, support members 10L, 10M, and 10R for supporting the ladder cords 7L, 7M, and 7R and the lifting and lowering cords 6L, 6M, and 6R are disposed, and the support members 10L, 10M, and 10R have a square bar shape. The drive shaft 12 is inserted (see FIGS. 4 and 5 described later). A tilt drum (not shown) is rotatably supported by such support members 10L, 10M, and 10R, and the drive shaft is inserted into the tilt drum so as not to be relatively rotatable. Therefore, when the drive shaft 12 is rotated, the tilt drum is rotated, and the angles of the multi-stage slats 4 suspended and supported by the ladder cords 7L, 7M, and 7R are adjusted.
 また、昇降コード6L,6M,6Rをヘッドボックス1内への引き込み又はヘッドボックス1からの引き出し可能にするために、当該支持部材10L,10M,10Rには、当該駆動軸12に対して相対回転不能に取着される巻取軸11が設けられている(後述する図4及び図5参照)。したがって、この駆動軸12が回転されると、当該チルトドラムが回転し、ラダーコード7L,7M,7Rにより吊下支持された多数段のスラット4の角度が水平方向に対して略垂直方向にチルトされた後、当該巻取軸12による昇降コード6L,6M,6Rの巻取り、又は巻戻しが行われ、ボトムレール8を昇降させることによりスラット4を昇降させることができる。 Further, the support members 10L, 10M, and 10R are relatively rotated with respect to the drive shaft 12 so that the elevating cords 6L, 6M, and 6R can be drawn into the head box 1 or pulled out from the head box 1. A winding shaft 11 that is impossiblely attached is provided (see FIGS. 4 and 5 described later). Therefore, when the drive shaft 12 is rotated, the tilt drum rotates, and the angles of the multi-stage slats 4 suspended and supported by the ladder cords 7L, 7M, and 7R are tilted in a substantially vertical direction with respect to the horizontal direction. After that, the lifting / lowering cords 6L, 6M, 6R are wound or rewound by the winding shaft 12, and the slats 4 can be moved up and down by moving the bottom rail 8 up and down.
 ヘッドボックス1の右端部側には、当該駆動軸12の回転を操作する操作プーリー(図示せず)が収容され、この操作プーリーに掛装される無端状の操作コード5が、ヘッドボックス1の右端部側の前面に設けられた導出口1aから垂下される。また、ヘッドボックス1内には、当該駆動軸12の回転をロック可能なストッパー装置が設けられる(図示せず)。したがって、操作コード5を操作することで、当該駆動軸12の回転を操作し、当該支持部材10L,10M,10Rを介してラダーコード7L,7M,7Rにより吊下支持された多数段のスラット4の角度を調整することや、昇降コード6L,6M,6Rにより多数段のスラット4を昇降させることができる。 An operation pulley (not shown) for operating the rotation of the drive shaft 12 is accommodated on the right end side of the head box 1, and an endless operation cord 5 hung on the operation pulley is connected to the head box 1. It hangs down from the outlet 1a provided on the front surface on the right end side. Further, a stopper device capable of locking the rotation of the drive shaft 12 is provided in the head box 1 (not shown). Therefore, by operating the operation cord 5, the rotation of the drive shaft 12 is operated, and the multi-stage slats 4 suspended and supported by the ladder cords 7L, 7M, 7R via the support members 10L, 10M, 10R. The slats 4 of a plurality of stages can be moved up and down by adjusting the angle of the slats 4 and the lifting cords 6L, 6M, 6R.
 本実施形態の横型ブラインドでは、図2に示すように、複数の昇降コード(本例では、6L,6M,6R)のうち各スラット4の長手方向(即ち、左右方向)の両端部から最近位置にてヘッドボックス1から垂下される昇降コード6L,6Rについては、各スラット4の短手方向(即ち、前後方向)の一縁部(室外側縁部)近傍に設けられた当該短手方向に延びる長孔状の挿通孔4aに挿通して垂下するよう構成し、ボトムレール8の上面における室外側縁部近傍に設けられた貫通部8L,8Rを経て底面側に係止して取着する。そして、当該各スラット4の長手方向(即ち、左右方向)の両端部から最近位置にて垂下される昇降コード6L,6R以外の昇降コードのうち少なくとも1本(即ち、本例では昇降コード6M)については、各スラット4の短手方向の他縁部(室内側縁部)に沿って垂下し、ボトムレール8の前側面に沿って底面に設けられた取付部8Mに係止して取着する。この長孔状の挿通孔4aは、各スラット4の短手方向の一縁部(室外側縁部)から各スラット4の短手方向の中央部までの範囲内で延びるよう形成するのが好適である。そして、各スラット4は、ヘッドボックス1の長手方向における複数個所に配設して吊下される一対のラダーコード7L(又は7M,7R)間に所定間隔で接続された横糸7a,7bに載置されてそれぞれ支持されている。 In the horizontal blind according to the present embodiment, as shown in FIG. 2, the closest position from both ends in the longitudinal direction (that is, the left-right direction) of each slat 4 among a plurality of lifting cords (6L, 6M, 6R in this example). As for the elevating cords 6L and 6R suspended from the head box 1, the lateral direction of each slat 4 (that is, the front-rear direction) is provided in the short direction provided near one edge (outdoor edge). It is configured to pass through and extend through an elongated long insertion hole 4a, and is fixed to the bottom surface side through through portions 8L and 8R provided in the vicinity of the outdoor edge on the upper surface of the bottom rail 8. . Then, at least one of the lifting / lowering cords other than the lifting / lowering cords 6L and 6R hanging from the both ends in the longitudinal direction (that is, the left / right direction) of each slat 4 (that is, the lifting / lowering cord 6M in this example). Is suspended along the other edge (inner side edge) of each slat 4 in the short direction, and is attached to the attachment portion 8M provided on the bottom surface along the front side surface of the bottom rail 8. To do. The long hole-like insertion hole 4a is preferably formed so as to extend within a range from one edge portion (outdoor edge portion) of each slat 4 in the short direction to the center portion of each slat 4 in the short direction. It is. Each slat 4 is mounted on a weft thread 7a, 7b connected at a predetermined interval between a pair of ladder cords 7L (or 7M, 7R) that are arranged and suspended at a plurality of locations in the longitudinal direction of the head box 1. Each is supported.
 長孔状の挿通孔4aは、各スラット4のチルト動作を妨げることなく、且つ各スラット4が遮蔽状態となるようチルトされる際に、各スラット4の縁部で少なくとも挿通孔4aの一部が遮蔽される位置に形成されている。 The long hole-like insertion holes 4a are not obstructed by the tilting operation of the slats 4 and when the slats 4 are tilted so as to be in a shielding state, at least a part of the insertion holes 4a at the edges of the slats 4. Is formed at a position to be shielded.
 より具体的には、図3に示すように、昇降コード6L,6Rを挿通するべく、各スラット4の短手方向(即ち、前後方向)の室外側縁部近傍に長孔状の挿通孔4aを形成することで、各スラット4の水平状態(図3(a)参照)や、各スラット4のチルト状態(図3(b)参照)の際にも、昇降コード6L,6Rをその吊下に係る鉛直方向へと負担なく張設させることができる。また、長孔状の挿通孔4aは室外側縁部近傍に設けられるため、図3(b)に示すように、当該挿通孔4aからの光漏れを抑制し、外部光に対する遮蔽性を高めている。特に、本実施形態の横型ブラインドにおけるスラット4における長孔状の挿通孔4aは、各スラット4のチルト動作を伴う降下性能を向上させるべく、深さ方向にテーパ41を有するように構成している。 More specifically, as shown in FIG. 3, in order to insert the lifting / lowering cords 6L and 6R, a long hole-like insertion hole 4a is formed in the vicinity of the outdoor side edge of each slat 4 in the short direction (that is, the front-rear direction). In the horizontal state (see FIG. 3A) of each slat 4 and the tilted state of each slat 4 (see FIG. 3B), the lifting cords 6L and 6R are suspended. It can be stretched without any burden in the vertical direction. In addition, since the long hole-shaped insertion hole 4a is provided in the vicinity of the outdoor edge, as shown in FIG. 3B, light leakage from the insertion hole 4a is suppressed, and the shielding property against external light is enhanced. Yes. In particular, the long hole-like insertion hole 4a in the slat 4 in the horizontal blind according to the present embodiment is configured to have a taper 41 in the depth direction in order to improve the descending performance accompanying the tilting operation of each slat 4. .
 ここで、本実施形態の横型ブラインドにて、幅広のスラット4を実施例1とし、幅狭のスラット4を実施例2として、それぞれの実施例の長孔状の挿通孔4aについて順に説明する。 Here, in the horizontal blind according to the present embodiment, the wide slat 4 is referred to as Example 1 and the narrow slat 4 is referred to as Example 2, and the elongated insertion holes 4a of the respective examples will be described in order.
(実施例1のスラット)
 図4(a),(b)は、本実施形態の横型ブラインドにて、実施例1のスラット4の長孔状の挿通孔4aの形状を説明する部分的な平面図とその断面図を示している。また、図4(c)は、実施例1のスラット4に対する昇降コード6L(又は6R)の垂下を説明する部分的な側面断面図を示している。
(Slat of Example 1)
4 (a) and 4 (b) show a partial plan view and a cross-sectional view illustrating the shape of the elongated insertion hole 4a of the slat 4 of Example 1 in the horizontal blind according to the present embodiment. ing. FIG. 4C shows a partial side cross-sectional view for explaining the hanging of the elevating cord 6L (or 6R) with respect to the slat 4 of the first embodiment.
 実施例1におけるスラット4では、図4(c)に示すように、当該挿通孔4aに挿通される昇降コード6L(又は6R)の巻取軸11からの垂下位置が当該挿通孔4aよりも概ね室内側に位置する際に、巻取軸11の下方に設けられた転向滑車13L(又は13R)の室外側案内面に当接させて当該昇降コード6L(又は6R)を垂下するよう構成した例である。 In the slat 4 according to the first embodiment, as shown in FIG. 4C, the hanging position of the lifting / lowering cord 6L (or 6R) inserted through the insertion hole 4a from the take-up shaft 11 is substantially larger than that of the insertion hole 4a. An example in which the lift cord 6L (or 6R) is suspended by being brought into contact with the outdoor guide surface of the turning pulley 13L (or 13R) provided below the winding shaft 11 when positioned on the indoor side. It is.
 各スラット4のチルト動作を伴う降下性能を向上させるには、昇降コード6L(又は6R)とスラット4の挿通孔4aとの間で摩擦による抵抗が大きくならないようにすることが重要となる。そこで、実施例1のスラット4における長孔状の挿通孔4aは、図4(a),(b)に示すように、各スラット4のチルト動作を伴う降下性能を向上させるべく、深さ方向にテーパ41が設けられている。このテーパ41は、降下操作時にチルトされる各スラット4に対して、長孔状の挿通孔4aに挿通される昇降コード6L(又は6R)の挿通性を維持するよう傾斜している。尚、図4(c)には、転向滑車13Mの室内側案内面に当接させて昇降コード6Mをスラット4の室内側縁部に沿って垂下させている様子をその対比のために破線で図示している。 In order to improve the descending performance accompanying the tilting operation of each slat 4, it is important that the resistance due to friction does not increase between the lifting / lowering cord 6L (or 6R) and the insertion hole 4a of the slat 4. Therefore, the long hole-like insertion hole 4a in the slat 4 of the first embodiment is formed in the depth direction in order to improve the descending performance accompanied by the tilting operation of each slat 4, as shown in FIGS. 4 (a) and 4 (b). A taper 41 is provided. The taper 41 is inclined so as to maintain the insertability of the elevating cord 6L (or 6R) inserted into the elongated insertion hole 4a with respect to each slat 4 tilted during the lowering operation. In FIG. 4 (c), the broken cord 6M is suspended along the indoor side edge of the slat 4 in contact with the indoor side guide surface of the turning pulley 13M by a broken line for comparison. It is shown.
 そして、図5に示すように、長孔状の挿通孔4aに挿通される昇降コード6L(又は6R)は、当該複数段のスラット4の降下時に、ヘッドボックス1(支持部材13Lや13R)からボトムレール8に向けて略鉛直方向に垂下されるよう構成されている。 As shown in FIG. 5, the lifting / lowering cord 6L (or 6R) inserted through the elongated insertion hole 4a is removed from the head box 1 ( support members 13L and 13R) when the slats 4 are lowered. It is configured to hang down in a substantially vertical direction toward the bottom rail 8.
 このように、挿通孔4aにはテーパ41が設けられているため、昇降コード6L(又は6R)とスラット4の挿通孔4aとの間で摩擦による抵抗が大きくならない。そして、挿通孔4aに挿通される昇降コード6L(又は6R)をヘッドボックス1(支持部材13Lや13R)からボトムレール8に向けて略鉛直方向に垂下されるよう構成することで、屈曲させて垂下させる場合よりもその降下性能を向上させることができる。 Thus, since the insertion hole 4a is provided with the taper 41, the resistance due to friction does not increase between the lifting / lowering cord 6L (or 6R) and the insertion hole 4a of the slat 4. Then, the lifting / lowering cord 6L (or 6R) inserted through the insertion hole 4a is bent by being configured to hang in the substantially vertical direction from the head box 1 (supporting members 13L and 13R) toward the bottom rail 8. The descent performance can be improved as compared with the case of hanging.

 実施例2におけるスラット4では、図6(c)に示すように、当該挿通孔4aに挿通される昇降コード6L(又は6R)の巻取軸11からの垂下位置が当該挿通孔4aよりも概ね室外側に位置する際に、巻取軸11の下方に設けられた転向滑車13L(又は13R)の室内側案内面に当接させて当該昇降コード6L(又は6R)を垂下するよう構成した例である。 In the slat 4 in the second embodiment, as shown in FIG. 6C, the hanging position of the lifting / lowering cord 6L (or 6R) inserted through the insertion hole 4a from the take-up shaft 11 is substantially larger than that of the insertion hole 4a. An example in which the lifting cord 6L (or 6R) is suspended by being brought into contact with the indoor guide surface of the turning pulley 13L (or 13R) provided below the winding shaft 11 when positioned on the outdoor side. It is.
 実施例2のスラット4における長孔状の挿通孔4aにおいても、図6(a),(b)に示すように、各スラット4のチルト動作を伴う降下性能を向上させるべく、深さ方向にテーパ41が設けられている。このテーパ41は、降下操作時にチルトされる各スラット4に対して、長孔状の挿通孔4aに挿通される昇降コード6L(又は6R)の挿通性を維持するよう傾斜している。尚、図6(c)には、転向滑車13Mの室内側案内面に当接させて昇降コード6Mをスラット4の室内側縁部に沿って垂下させている様子をその対比のために破線で図示している。 Also in the long hole-like insertion hole 4a in the slat 4 of the second embodiment, as shown in FIGS. 6A and 6B, in order to improve the descending performance accompanying the tilting operation of each slat 4, A taper 41 is provided. The taper 41 is inclined so as to maintain the insertability of the elevating cord 6L (or 6R) inserted into the elongated insertion hole 4a with respect to each slat 4 tilted during the lowering operation. In FIG. 6 (c), the broken cord 6M is suspended along the indoor side edge of the slat 4 by being brought into contact with the indoor side guide surface of the turning pulley 13M and is shown by a broken line for comparison. It is shown.
 したがって、実施例2のスラット4に対しても、前述した図5に示す例と同様に、長孔状の挿通孔4aに挿通される昇降コード6L(又は6R)は、当該複数段のスラット4の降下時に、ヘッドボックス1(支持部材13Lや13R)からボトムレール8に向けて略鉛直方向に垂下されるよう構成されている。 Therefore, the lift cord 6L (or 6R) inserted into the long hole-like insertion hole 4a is also provided to the slats 4 of the second embodiment as in the example shown in FIG. Is configured to hang in a substantially vertical direction from the head box 1 ( support members 13L and 13R) toward the bottom rail 8.
 このように、実施例2のスラット4においても、挿通孔4aにはテーパ41が設けられているため、昇降コード6L(又は6R)とスラット4の挿通孔4aとの間で摩擦による抵抗が大きくならない。そして、挿通孔4aに挿通される昇降コード6L(又は6R)をヘッドボックス1(支持部材13Lや13R)からボトムレール8に向けて略鉛直方向に垂下されるよう構成することで、屈曲させて垂下させる場合よりもその降下性能を安定化させることができるようになる。 Thus, also in the slat 4 of the second embodiment, since the insertion hole 4a is provided with the taper 41, the resistance due to friction between the elevating cord 6L (or 6R) and the insertion hole 4a of the slat 4 is large. Don't be. Then, the lifting / lowering cord 6L (or 6R) inserted through the insertion hole 4a is bent by being configured to hang in the substantially vertical direction from the head box 1 (supporting members 13L and 13R) toward the bottom rail 8. The descent performance can be stabilized as compared with the case of hanging.
 尚、当該挿通孔4aに挿通される昇降コード6L(又は6R)の巻取軸11からの垂下位置が当該挿通孔4aとほぼ同一となるとき(即ち、巻取軸11から略鉛直方向の垂下で当該挿通孔4aに挿通可能であるとき)は、巻取軸11の下方に設けられた転向滑車13L(又は13R)の室内側案内面と室外側案内面のいずれかに当接させて当該昇降コード6L(又は6R)を垂下することができ、或いは転向滑車13L(又は13R)自体の使用も不要とすることも可能である。 When the hanging position of the lifting / lowering cord 6L (or 6R) inserted through the insertion hole 4a from the winding shaft 11 is substantially the same as that of the insertion hole 4a (that is, hanging from the winding shaft 11 in a substantially vertical direction). And when it can be inserted through the insertion hole 4a), it is brought into contact with either the indoor side guide surface or the outdoor side guide surface of the turning pulley 13L (or 13R) provided below the winding shaft 11. The lifting / lowering cord 6L (or 6R) can be suspended, or the use of the turning pulley 13L (or 13R) itself can be eliminated.
 また、本実施形態のように3本の昇降コード6L,6M,6Rとする以外にも、4本又はそれ以上の昇降コードを用いる形態とすることができる。この場合、複数の昇降コードのうち少なくとも2本の昇降コードは当該長孔状の挿通孔4aに挿通して垂下させ、該少なくとも2本の昇降コード以外の昇降コードのうち、少なくとも1本の昇降コードは、各スラット4の短手方向の他縁部に沿って垂下させる。 Further, in addition to the three lifting / lowering cords 6L, 6M, and 6R as in the present embodiment, four or more lifting / lowering cords may be used. In this case, at least two lifting / lowering cords out of the plurality of lifting / lowering cords are inserted into the elongated hole-like insertion hole 4a and suspended, and at least one lifting / lowering cord other than the at least two lifting / lowering cords is lifted / lowered. The cord hangs along the other edge of each slat 4 in the short direction.
 このとき、当該複数の昇降コードのうち当該複数段のスラット4の各々の長手方向の「両端部から最近位置」にて垂下される昇降コード(図1及び図2の例では、昇降コード6L,6R)は、各スラット4の短手方向の一縁部(室外側縁部)近傍に設けられた当該短手方向に延びる長孔状の挿通孔4aに挿通させるように構成し、当該長孔状の挿通孔4aに挿通される昇降コード以外の昇降コード(図1及び図2の例では、昇降コード6M)は全て、切欠きや挿通孔を利用せずに、各スラット4の短手方向の他縁部(室内側縁部)に沿って垂下させるように構成するのが好適である。これにより、挿通孔4aの数を減少させてより効果的に、昇降コードとスラットとの摩擦による抵抗を減少させ、且つ光漏れを効果的に抑制することができる。 At this time, among the plurality of lifting cords, the lifting cords hanging down at the “longest position from both ends” of each of the plurality of slats 4 (in the example of FIGS. 1 and 2, the lifting cord 6L, 6R) is configured to be inserted into a long hole-like insertion hole 4a extending in the short direction provided in the vicinity of one edge (outdoor edge) of each slat 4 in the short direction. All the lifting / lowering cords (lifting / lowering cord 6M in the examples of FIGS. 1 and 2) inserted into the through-holes 4a without using the notches or the insertion holes are short direction of each slat 4 It is preferable to make it hang along the other edge (inner side edge). As a result, the number of insertion holes 4a can be reduced to more effectively reduce the resistance caused by the friction between the lifting / lowering cord and the slat, and the light leakage can be effectively suppressed.
 尚、図1及び図2に示すように、本実施形態の横型ブラインドでは、スラット4の短手方向(即ち、前後方向)に互いに対向して一対のラダーコード7L,7M,7Rが吊下され、一対のラダーコード7L間には、X字状に交差する横糸7a,7bが所定間隔で接続され、図7に示すように、この横糸7a,7b上にスラット4が上乗せされている。同様に、一対のラダーコード7M(又は7R)間には、X字状に交差する横糸7a,7bが所定間隔で接続され、この横糸7a,7b上にスラット4が上乗せされている。 As shown in FIGS. 1 and 2, in the horizontal blind according to the present embodiment, a pair of ladder cords 7L, 7M, and 7R are suspended so as to face each other in the short direction (that is, the front-rear direction) of the slat 4. Between the pair of ladder cords 7L, wefts 7a and 7b intersecting in an X shape are connected at a predetermined interval, and as shown in FIG. 7, the slats 4 are placed on the wefts 7a and 7b. Similarly, between the pair of ladder cords 7M (or 7R), weft yarns 7a and 7b intersecting in an X shape are connected at a predetermined interval, and the slat 4 is placed on the weft yarns 7a and 7b.
 即ち、本実施形態の横型ブラインドにおけるスラット4は、図1及び図7に示すように、木製等の屈曲不能な硬質材料からなる平板状の形態を有している。この硬質材料からなる平板状のスラット4を当該X字状に交差する横糸7a,7b間に挿通しながら組み立てることは容易とは云えない。このため、この硬質材料からなる平板状のスラット4を当該X字状に交差する横糸7a,7bに上乗せするよう構成することで、組立性を改善することができる。 That is, as shown in FIGS. 1 and 7, the slat 4 in the horizontal blind according to the present embodiment has a flat plate shape made of a hard material such as wood that cannot be bent. It cannot be said that it is easy to assemble the flat slat 4 made of a hard material while being inserted between the wefts 7a and 7b intersecting in the X shape. For this reason, the assemblability can be improved by constructing the flat slats 4 made of the hard material on the wefts 7a and 7b intersecting in the X shape.
 そして、図7に示すように、複数段のスラット4に対して、昇降コード6L(又は6R)を所定段置き(図示する例では5段置き)に各横糸7a,7bに対して編み込むよう構成するのが好適である。また、昇降コード6L,6Rの各横糸7a,7bに対する編み込みは、スラット4毎に、その長手方向の中央部を基点として、互いに対称となるように編み込むのが好適である。例えば、図7に示すように、或るスラット4について、昇降コード6L,6Rは、対応する横糸7a,7bに対して当該中央部側に挿通する。別のスラット4については、昇降コード6L,6Mは、対応する横糸7a,7bに対して当該中央部とは逆の外縁部側に挿通する。 Then, as shown in FIG. 7, the lifting cord 6L (or 6R) is knitted into each weft yarn 7a, 7b in a predetermined step (every five steps in the illustrated example) with respect to a plurality of slats 4. It is preferable to do this. The weaving cords 6L and 6R with respect to the weft yarns 7a and 7b are preferably knitted for each slat 4 so as to be symmetrical with respect to the central portion in the longitudinal direction. For example, as shown in FIG. 7, for a certain slat 4, the lifting / lowering cords 6 </ b> L and 6 </ b> R are inserted through the corresponding weft yarns 7 a and 7 b toward the center portion. For another slat 4, the lifting cords 6L and 6M are inserted into the corresponding weft yarns 7a and 7b on the outer edge side opposite to the central portion.
 昇降コード6Mについては、同様に、複数段のスラット4に対して所定段置き(図示する例では5段置き)に各横糸7a,7bに対して編み込むよう構成することができるが、美観の観点から各横糸7a,7b間に挿通するのが好ましい(図2参照)。或いは、連続する上下段のスラット4間で、各横糸7a,7b間に編み込んで挿通する際に、上側スラット4では横糸7aの右側且つ横糸7bの左側に昇降コード6Mを挿通し、下側スラット4では横糸7aの左側且つ横糸7bの右側に昇降コード6Mを挿通して、編み込む態様とすることもできる(図示せず)。 Similarly, the lifting / lowering cord 6M can be configured so as to be knitted into the weft yarns 7a and 7b in predetermined steps (in the example shown, every five steps) with respect to the slats 4 of a plurality of steps. Is preferably inserted between the wefts 7a and 7b (see FIG. 2). Alternatively, when the upper and lower slats 4 are knitted between the weft yarns 7a and 7b and inserted through the upper and lower slats 4, the lifting cord 6M is inserted into the right side of the weft yarn 7a and the left side of the weft yarn 7b. 4, the lifting cord 6M may be inserted into the left side of the weft thread 7a and the right side of the weft thread 7b so as to be knitted (not shown).
 このように、少なくとも昇降コード6L,6Mを所定段置きに各横糸7a,7bに対して編み込むよう構成することで、各横糸7a,7bに単にスラット4を上乗せした態様であっても、各スラット4の横ずれ(図8(a)参照)やねじれ(図8(b)参照)を抑制しつつ組立性を改善することができる。 As described above, even if the slats 4 are simply placed on the respective weft yarns 7a and 7b by constructing at least the elevating cords 6L and 6M into the weft yarns 7a and 7b in predetermined steps, each slat Assembling property can be improved while suppressing lateral displacement of 4 (see FIG. 8A) and twisting (see FIG. 8B).
 また、ボトムレール8の上面に、複数の昇降コード6L,6Rの垂下位置に応じてそれぞれ貫通部8L,8Rを設けるようにしたため、複数の昇降コード6L,6Rを略鉛直方向に垂下させることができる。これにより、各スラット4の昇降動作やチルト動作を円滑化させることができる。 Further, since the through portions 8L and 8R are provided on the upper surface of the bottom rail 8 in accordance with the hanging positions of the plurality of lifting / lowering cords 6L and 6R, respectively, the plurality of lifting / lowering cords 6L and 6R can be suspended in a substantially vertical direction. it can. Thereby, the raising / lowering operation | movement and tilting operation | movement of each slat 4 can be made smooth.
(実施例3,4のスラット)
 上述した例では、幅広のスラット4を実施例1とし、幅狭のスラット4を実施例2として、支持部材10L,10Rにおける巻取軸11の下方に設けられた転向滑車13L(又は13R)の室内側案内面に当接させるか、室外側案内面に当接させるかにより、各実施例1,2のスラット4のいずれに対しても適用可能に支持部材10L,10Rを構成した。したがって、支持部材10L,10Rの構成を共通化できるという利点がある。
(Slats of Examples 3 and 4)
In the above-described example, the wide slat 4 is referred to as Example 1, and the narrow slat 4 is referred to as Example 2, and the turning pulley 13L (or 13R) provided below the winding shaft 11 in the support members 10L and 10R is used. The support members 10L and 10R are configured to be applicable to any of the slats 4 of the first and second embodiments, depending on whether they are brought into contact with the indoor guide surface or the outdoor guide surface. Therefore, there is an advantage that the configuration of the support members 10L and 10R can be made common.
 一方、スラット4の構成の違いによって支持部材10L,10Rの構成の共通化が要求されない用途のときは、以下に説明するような実施例3のスラット4のように構成することができ、組立性の簡便さが要求されない用途のときは、以下に説明するような実施例4のスラット4のように構成することができる。図9(a),(b)は、それぞれ本発明による一実施形態の横型ブラインドにおける実施例3,4のスラットの降下時の動作を示す側面断面図である。 On the other hand, when the usage of the support members 10L and 10R is not required due to the difference in the configuration of the slat 4, it can be configured like the slat 4 of the third embodiment as described below. When the use is not required, it can be configured like the slat 4 of Example 4 as described below. FIGS. 9A and 9B are side cross-sectional views showing the operation of the slats of Examples 3 and 4 when the horizontal blind according to the embodiment of the present invention is lowered.
 各スラット4のチルト動作を伴う降下性能を向上させる観点から、スラット4に対する昇降コード6L(又は6R)の摩擦による抵抗が大きくならないように、長孔状の挿通孔4aが深さ方向にテーパを有するよう構成すればよい。このため、実施例3として図9(a)に示すように、長孔状の挿通孔4aを各スラット4の短手方向(前後方向)幅の略中央に設けた場合にも、各スラット4のチルト動作を伴う降下性能を向上させることができる。図9(a)に示す例においても、長孔状の挿通孔4aに挿通される昇降コード6L(又は6R)は、当該複数段のスラット4の降下時に、ヘッドボックス1(支持部材13Lや13R)からボトムレール8に向けて略鉛直方向に垂下されるよう構成することができる。 From the viewpoint of improving the descent performance accompanied by the tilting operation of each slat 4, the long hole-like insertion hole 4 a is tapered in the depth direction so that the resistance due to the friction of the elevating cord 6 </ b> L (or 6 </ b> R) against the slat 4 does not increase. What is necessary is just to comprise. Therefore, as shown in FIG. 9A as the third embodiment, each slat 4 is provided even when the long hole-like insertion hole 4a is provided at the approximate center of the width in the short direction (front-rear direction) of each slat 4. It is possible to improve the descent performance accompanied by the tilting operation. In the example shown in FIG. 9A as well, the lifting / lowering cord 6L (or 6R) inserted through the elongated insertion hole 4a is the head box 1 ( support members 13L and 13R) when the slats 4 of the plurality of stages are lowered. ) To the bottom rail 8 in a substantially vertical direction.
 また、実施例4として図9(b)に示すように、長孔状の挿通孔4aの代わりに、切欠き4bで構成し、この切欠き4bが深さ方向にテーパを有するよう構成した場合も、各スラット4のチルト動作を伴う降下性能を向上させることができる。そして、図9(b)に示す例においても、切欠き4bに挿通される昇降コード6L(又は6R)は、当該複数段のスラット4の降下時に、ヘッドボックス1(支持部材13Lや13R)からボトムレール8に向けて略鉛直方向に垂下されるよう構成することができる。 In addition, as shown in FIG. 9 (b) as the fourth embodiment, instead of the elongated insertion hole 4a, a notch 4b is formed, and the notch 4b has a taper in the depth direction. Moreover, the descent performance accompanying the tilting operation of each slat 4 can be improved. In the example shown in FIG. 9 (b), the lifting / lowering cord 6L (or 6R) inserted through the notch 4b is removed from the head box 1 ( support members 13L and 13R) when the slats 4 of the plurality of stages are lowered. It can be configured to hang down in a substantially vertical direction toward the bottom rail 8.
 以上のように、本実施形態の横型ブラインドは、各スラット4の短手方向(即ち、前後方向)に互いに対向する一対のラダーコード7L,7M,7Rが、ヘッドボックス1の長手方向における複数個所に配設して吊下され、複数の昇降コード6L,6M,6Rが各一対のラダーコード7L,7M,7Rの近傍位置でヘッドボックス1から垂下され、少なくとも2本の昇降コード、好適には各スラット4の長手方向(即ち、左右方向)の両端部から最近位置にてヘッドボックス1から垂下される昇降コード6L,6Rについては、各スラットの短手方向の一縁部(室外側縁部)近傍又は中央部に設けられた当該短手方向に延びる長孔状の挿通孔4a、或いは室外側縁部近傍に設けられた切欠き4bに挿通して垂下し、当該昇降コード6L,6R以外の昇降コードのうち少なくとも1本(即ち、本例では昇降コード6M)は、各スラット4の他縁部(室内側縁部)に沿って垂下するよう構成している。尚、横型ブラインドの用途によって長孔状の挿通孔4a又は切欠き4bの位置(室外側縁部、中央部、及び室内側縁部等)を変更してもよく、前述した実施形態の例は好適例であり、これに限定する必要はない。 As described above, in the horizontal blind according to the present embodiment, the pair of ladder cords 7L, 7M, and 7R facing each other in the short direction (that is, the front-rear direction) of each slat 4 has a plurality of locations in the longitudinal direction of the head box 1. A plurality of lifting / lowering cords 6L, 6M and 6R are suspended from the head box 1 in the vicinity of each pair of ladder cords 7L, 7M and 7R, and at least two lifting / lowering cords, preferably With respect to the lifting cords 6L and 6R hanging from the head box 1 at the closest position from both ends in the longitudinal direction (ie, left and right direction) of each slat 4, one edge (outdoor edge) of each slat in the short direction ) The elevating cords 6L and 6 are suspended by being inserted into a long hole-like insertion hole 4a provided in the vicinity or the central part and extending in the short direction or a notch 4b provided in the vicinity of the outdoor edge. At least one of the lift cords other than (i.e., lift cords 6M in this example) is configured to droop along the other edge of each slat 4 (indoor side edges). The position of the long hole-like insertion hole 4a or notch 4b (outdoor edge, center, indoor edge, etc.) may be changed depending on the use of the horizontal blind. This is a preferred example and need not be limited to this.
 特に、本実施形態の横型ブラインドでは、長孔状の挿通孔4a又は切欠き4bには、深さ方向にテーパ41が設けられている。このテーパ41は、降下操作時にチルトされる各スラット4に対して、長孔状の挿通孔4a又は切欠き4bに挿通される昇降コード6L(又は6R)の挿通性を維持するよう傾斜している。 In particular, in the horizontal blind according to the present embodiment, the long hole-shaped insertion hole 4a or the notch 4b is provided with a taper 41 in the depth direction. The taper 41 is inclined with respect to each slat 4 tilted during the lowering operation so as to maintain the insertion property of the elevating cord 6L (or 6R) inserted through the long insertion hole 4a or the notch 4b. Yes.
 これにより、昇降コード6L(又は6R)とスラット4の挿通孔4a又は切欠き4bとの間で摩擦による抵抗が大きくならないようにすることができ、各スラット4のチルト動作を伴う降下性能を向上させることができる。 Thereby, it is possible to prevent the frictional resistance from increasing between the elevating cord 6L (or 6R) and the insertion hole 4a or the notch 4b of the slat 4, and to improve the descent performance accompanied by the tilting operation of each slat 4. Can be made.
 また、本実施形態の横型ブラインドでは、長孔状の挿通孔4a又は切欠き4bに挿通される昇降コード6L(又は6R)は、当該複数段のスラット4の降下時に、ヘッドボックス1(支持部材13Lや13R)からボトムレール8に向けて略鉛直方向に垂下されるよう構成した。特に、挿通孔4a又は切欠き4bに挿通される昇降コード6L(又は6R)の巻取軸11からの垂下位置が当該挿通孔4aよりも室内側に位置するか否かによって、巻取軸11の下方に設けられた転向滑車13L(又は13R)に当接させる案内面を選択的に設置するよう構成した。これにより、複数種のスラット4に対して、その支持部材の構成を共通化することができる。 Further, in the horizontal blind according to the present embodiment, the lifting / lowering cord 6L (or 6R) inserted through the long hole-like insertion hole 4a or the notch 4b is provided with the head box 1 (supporting member) when the slat 4 is lowered. 13L or 13R) is suspended in a substantially vertical direction toward the bottom rail 8. In particular, the winding shaft 11 depends on whether or not the hanging position of the lifting / lowering cord 6L (or 6R) inserted through the insertion hole 4a or the notch 4b from the winding shaft 11 is located on the indoor side of the insertion hole 4a. The guide surface to be brought into contact with the turning pulley 13L (or 13R) provided below is selectively installed. Thereby, the structure of the support member can be made common to the plurality of types of slats 4.
 このように、挿通孔4a又は切欠き4bに挿通される昇降コード6L(又は6R)をヘッドボックス1(支持部材13Lや13R)からボトムレール8に向けて略鉛直方向に垂下されるよう構成することで、屈曲させて垂下させる場合よりもその降下性能を向上させることができる。 In this manner, the lifting / lowering cord 6L (or 6R) inserted through the insertion hole 4a or the notch 4b is configured to hang in a substantially vertical direction from the head box 1 ( support members 13L and 13R) toward the bottom rail 8. As a result, the descending performance can be improved as compared with the case of being bent and suspended.
 また、本実施形態の横型ブラインドでは、長孔状の挿通孔4a又は切欠き4bに挿通される昇降コード6L(又は6R)は、当該複数段のスラット4より下方に設置されるボトムレール8の上面から取着するよう構成した。 In the horizontal blind according to the present embodiment, the lifting / lowering cord 6L (or 6R) inserted through the long hole-like insertion hole 4a or the notch 4b is provided on the bottom rail 8 installed below the slats 4 of the plurality of stages. It was configured to be attached from the top.
 これにより、当該昇降コード6L(又は6R)の略鉛直方向への垂下を確実にし、屈曲させて垂下させる場合よりもその降下性能を向上させることができる。 This ensures that the lifting / lowering cord 6L (or 6R) hangs down in a substantially vertical direction and can improve its descent performance as compared with the case where it is bent and hanged down.
 以上、特定の実施形態の例を挙げて本発明を説明したが、本発明は前述の実施形態の例に限定されるものではなく、その技術思想を逸脱しない範囲で種々変形可能である。例えば、X字状に交差する横糸7a,7bを例示して説明したが、横糸7a,7bが交差せずに平行であってもよく、1本の横糸としてもよい。 As described above, the present invention has been described with reference to examples of specific embodiments, but the present invention is not limited to the examples of the above-described embodiments, and various modifications can be made without departing from the technical idea thereof. For example, the weft yarns 7a and 7b intersecting in an X shape have been described as an example, but the weft yarns 7a and 7b may be parallel without intersecting or may be a single weft yarn.
 また、長孔状の挿通孔4a又は切欠き4bに挿通する昇降コード(例えば、6L又は6R)は、スラット4の降下時に略鉛直方向とすればよく、スラット4の上昇時には必ずしも略鉛直方向とする必要はない。 Further, the lifting / lowering cord (for example, 6L or 6R) inserted into the long hole-shaped insertion hole 4a or the notch 4b may be in the substantially vertical direction when the slat 4 is lowered, and is not necessarily in the substantially vertical direction when the slat 4 is raised. do not have to.
 また、長孔状の挿通孔4a又は切欠き4bに挿通する昇降コード(例えば、6L又は6R)以外の昇降コード(例えば6M)は、各スラット4の短手方向の他縁部(室内側端部)に沿って垂下され、摩擦による抵抗も大きくならないため、略鉛直方向へと垂下する必要はない。 Further, the lifting / lowering cord (for example, 6M) other than the lifting / lowering cord (for example, 6L or 6R) inserted into the long hole-shaped insertion hole 4a or the notch 4b is connected to the other edge portion (inner side end) of each slat 4 in the short direction. ) And the frictional resistance does not increase, so there is no need to hang in a substantially vertical direction.
 また、前述した実施形態の横型ブラインドにおいて、操作コード5による操作とする代わりに、外部スイッチ等からの操作により電動で動作するよう構成してもよい。また、「昇降コード」とは、紐状やテープ状のものを含む。 Further, in the horizontal blind according to the above-described embodiment, instead of the operation by the operation code 5, it may be configured to operate electrically by an operation from an external switch or the like. The “elevating cord” includes a string shape or a tape shape.
 本発明によれば、スラットの降下性能を向上させることができるので、複数の昇降コードを利用する横型ブラインドの用途に有用である。 According to the present invention, since the descent performance of the slat can be improved, it is useful for a horizontal blind using a plurality of lifting cords.
