AUTOMATIC OPENING/CLOSING DOOR OR AUTOMATIC OPENING/CLOSING FOLDING DOOR
PROBLEM TO BE SOLVED: To prevent an object being caught by a door when the door closes while passing, by surely performing detection of an object passing a door entrance, as a safety light ray is not shielded by an edge of the door when the door performs an opening/closing operation.SOLUTION: An automatic opening/closing door includes: a vertical frame (102) which rotatably supports one piece of doors (2, 3) by a supporting member at a side end part, and on which an automatic door device (1) for driving the supporting member is mounted; a safety light ray switch (104) and a safety light ray switch (105) in which one is constituted by a light emitting element and the other one is constituted by a light receiving element, on a vertical frame (103). The automatic door continues the opening state of the doors as long as an object which is passing through the doors (2, 3) is being detected by the safety light ray switches (104, 105). At the position in which a safety light ray (106) at a side part on the opening/closing tip side of the doors (2, 3) is not shielded when the doors (2, 3) of the automatic opening/closing doors open/close, notches (100a, 100b, 101a, 101b) are provided from the side part of the doors (2, 3) to the opening/closing rear end side of the doors (2, 3).SELECTED DRAWING: Figure 1
【課題】 ドアが開閉動作してもドアの縁によって安全光線を遮ることがなく、ドア入り口を通過する物体の検知を確実に行い通過中にドアが閉じてドアに挟まれるのを防止する。【解決手段】 １枚のドア（２，３）を側端部で支持部材によって回動自在に支持し支持部材を駆動する自動ドア装置（１）を取り付ける竪枠（１０２）と竪枠（１０３）に一方が発光素子で、他方が受光素子で構成される安全光線スイッチ（１０４）と安全光線スイッチ（１０５）を備え、安全光線スイッチ（１０４，１０５）によってドア（２，３）を通過中の物体が検知されている限りドアの開放状態を継続させる自動開閉ドアであって、自動開閉ドアのドア（２，３）の開閉時にドア（２，３）の開閉先端側の辺部の安全光線（１０６）が遮られることのない位置に前記ドア（２，３）の辺部からドア（２，３）の開閉後端側に向かって切欠き（１００ａ，１００ｂ，１０１ａ，１０１ｂ）を設けたことを特徴とする。【選択図】 図１
