LOCKING DEVICE OF INWARD-OPENING DOOR
To provide a locking device of an inward-opening door capable of easily locking and unlocking the inward-opening door and capable of inwardly opening the door by pulling an operating lever.SOLUTION: A hand grip piece 10 is fixed on a stile 9 on a door end side, and an operating lever 21 is rotatably pivoted on a reverse face. An engagement hook part 23 is provided in the operating lever, and an engaging part 51 is provided in a vertical frame 49 of a frame body so as to engage with the engagement hook part 23 when a door is in a closed position. The operating lever 21 is energized by a spring 46 toward a direction in which the engagement hook part 23 engages with the engaging part 51. When the operating lever 21 is pulled, the engagement between the engagement hook part 23 and the engaging part 51 is released, and the door can be opened toward the inside.SELECTED DRAWING: Figure 5
【課題】内開き戸を簡単に施錠、解錠でき操作レバーを引いてそのまま戸を内開きできるようにした内開き戸の施錠装置を提供する。【解決手段】戸先側の竪框９に手掛け片１０を固定し、その裏面に操作レバー２１を回動自在に枢着する。操作レバーには、係合鈎部２３が設けられ、戸が閉鎖位置にあるとき係合鈎部２３に係合するよう枠体の竪枠４９に係止部５１が設けられている。上記操作レバー２１はばね４６で係合鈎部２３が係止部５１に係合する方向に付勢されている。操作レバー２１を引くと、係合鈎部２３と係止部５１の係合がはずれ、戸を内側に開くことができる。【選択図】図５
