AXIAL CONNECTION STRUCTURE OF BLIND
To eliminate the clearance between a square bar drive shaft and a square hole-shaped fitting hole in a boss section to improve the accuracy of slat angle control and bottom rail height control, or to improve the detection accuracy of the drive shaft rotation angle by a rotary encoder.SOLUTION: The present invention discloses a shaft connection structure of a blind in which slats of the blind are driven by a drive shaft 13 through a driven member 19. The drive shaft 13 is formed in the shape of a square bar, and square hole-shaped fitting holes 19c, which can be freely fitted to the drive shaft 13, are formed in a boss portion 19b of the driven member 19, respectively. A plurality of slits 19d extending radially from a center of the fitting hole 19c are formed in each of the boss portions 19b of the driven member 19, and a diameter reducing portion 26 for reducing the hole diameter of the fitting holes 19c is fitted to the areas of the boss portions 19b of the driven member 19 in which the plurality of slits 19d are formed.SELECTED DRAWING: Figure 1
【課題】角棒状の駆動軸とボス部の角孔状の嵌入孔とのクリアランスをなくして、スラットの角度制御やボトムレールの高さ制御の精度を向上し、或いはロータリエンコーダによる駆動軸の回転角の検出精度を向上する。【解決手段】本発明はブラインドのスラットが被駆動側部材１９を介して駆動軸１３により駆動されるブラインドの軸連結構造である。駆動軸１３が角棒状に形成され、駆動軸１３に遊嵌可能な角孔状の嵌入孔１９ｃが被駆動側部材１９のボス部１９ｂにそれぞれ形成される。嵌入孔１９ｃの中心から放射状に延びる複数のスリット１９ｄが被駆動側部材１９のボス部１９ｂにそれぞれ形成され、被駆動側部材１９のボス部１９ｂのうち複数のスリット１９ｄが形成された部分に嵌入孔１９ｃの孔径を縮小する縮径部材２６が嵌着可能に構成される。【選択図】図１
