Claims (2)
- 人の流れを円滑にするために円弧状の固定壁（３）の開口部を広くし、また、開口部を閉め切り人の流れを止めることを無くするために、三枚の扉をＹの字型に配置し、扉の外端部に袖扉（２）を円弧状の固定壁（３）に沿う形に備えた回転扉（１）としたもので、幅の狭い袖扉（２）を備えることで備えた袖扉（２）の幅と同じ幅だけ円弧状の固定壁（３）の開口部を広くでき、例えば袖扉（２）を円弧角度３０度の幅とすれば側壁の開口部は円弧角度９０度の幅と広くでき、幅の狭い袖扉（２）は人の流れの妨げとなる領域が少なく、円滑な人の流れとなる、袖扉（２）を備えた三枚扉の回転扉
- 袖扉（２）と円弧状の固定壁（３）の間で挟み込み等が起こった場合に、袖扉（２）で回転扉の停止距離以上の幅を軽くスライドさせて後退させることで、通行者に加わる過剰な力を逃がす逃がし袖扉（６）を設け、逃がし袖扉（６）に設けた定位置センサ（８）が外れることで回転扉の回転を停止させ、挟み込み事故の防止を計った請求項１記載の袖扉（２）を備えた三枚扉の回転扉
