WINDOW OPENING/CLOSING DEVICE AND OPENING/CLOSING WINDOW
PROBLEM TO BE SOLVED: To provide a window opening/closing device which includes a sash opening angle switching mechanism which can compactify depth and width of a base body and which does not cause increase in manufacturing cost.SOLUTION: A window opening/closing device 1 for opening/closing a sash includes: a worm 4 which extends substantially in an indoor outside direction by being supported by a base body 2 fixed to a window frame and which is coaxial with a driving shaft 3; a worm wheel 5 which meshes with the worm 4, and which oscillates around a vertical shaft core B1; an oscillation arm 6 which oscillates integrally with the worm wheel 5 and which extends in an outdoor direction horizontal plane; and a connection arm for connecting the oscillation arm 6 and the sash. The worm wheel 5 and the oscillation arm 6 are separate components. The oscillation arm 6 has a notch part 6E at a base end part 6A, and by protruding/retracting a locking piece 10 supported by the base body 2 and oscillating around the vertical shaft core B2 in the notch part 6E, a sash opening angle is switched between a fully-opened angle and a half-opened angle.SELECTED DRAWING: Figure 10
【課題】基体の奥行き及び幅をコンパクトにすることができるとともに製造コストが増大しない、障子開き角度切替機構を備えた窓開閉装置を提供する。【解決手段】窓枠に固定された基体２に支持されて略室内外方向に延びる、駆動軸３と同軸のウォーム４と、ウォーム４に噛み合い、垂直軸芯Ｂ１まわりに揺動するウォームホイール５と、ウォームホイール５と一体で揺動する、室外方向水平面内に延びる揺動アームと６、揺動アーム６と障子とを連結する連結アームとを含む、障子を開閉する窓開閉装置１であって、ウォームホイール５と揺動アーム６は別部品であり、揺動アーム６は、その基端部６Ａに切欠部６Ｅを有し、基体２に支持されて垂直軸芯Ｂ２まわりに揺動する係止片１０を切欠部６Ｅ内に出没させることにより、障子が開く角度を全開及び半開に切り替える。【選択図】図１０
