WINDOW OPENING/CLOSING DEVICE
To provide a window opening/closing device which can restrict a swing angle of a sash.SOLUTION: In a state where a restriction arm 7 for connecting a sash and a window frame and a connection part 91 are connected, a swing angle of the sash 5 is restricted to swing over a ventilation angle, and in a state where the connection is released, the sash 5 comes into a state of being able to swing over the ventilation angle. Thereby, in a window opening/closing device, in a state where the restriction arm 7 and the connection part 91 are connected, that is, in a state where the restriction arm 7 and a restriction unit 9 are connected, the maximum swing angle of the sash 5 is restricted to be equal to or less than the ventilation opening. Then, in a state where the connection is released, the sash 5 comes into a state of being able to swing over the ventilation angle, and by the elastic force of a spring, the restriction arm 7 automatically returns to a storage position.SELECTED DRAWING: Figure 7
【課題】 障子の揺動角度を規制可能な窓開閉装置の一例を開示する。【解決手段】 障子と窓枠とを連結するための規制アーム７と連結部９１とが連結された状態では、障子５の揺動角度が換気角度を越えて揺動することが規制され、かつ、当該連結が解除された状態では、障子５は、換気角度を越えて揺動可能な状態となる。これにより、当該窓開閉装置では、規制アーム７と連結部９１とが連結された状態、つまり、規制アーム７と規制ユニット９とが連結された状態では、障子５の最大揺動角度は換気開度以下に規制される。そして、当該連結が解除された状態では、障子５は、当該換気角度を越えて揺動可能な状態となるとともに、ばねの弾性力により、規制アーム７が自動的に収納位置に復帰する。【選択図】図７
