CEILING INSPECTION PORT
PROBLEM TO BE SOLVED: To provide a ceiling inspection port excellent in workability of maintenance, and capable of excellently maintaining an indoor scene.SOLUTION: A ceiling inspection port comprises an inspection port body 5 for rotatably connecting an inner frame 4 between a closing rotation position and an opening rotation position to an outer frame 3 fixed in an opening part 2 opened in the ceiling 1 and a lock body 6 movably installed in the inspection port body 5 between a closed operation position for restricting the inner frame 4 in the closing position and an opening operation position for releasing restriction, and any one of the inspection port body 5 and the lock body 6 is formed with a lock discrimination part 7 being easy in visual observation from an external part when the lock body 6 takes the opening operation position and being impossible in the visual observation when taking the closing operation position or becoming difficult in the visual observation.
【課題】メンテナンスの作業性に優れ、かつ、室内の景観を良好に維持することのできる天井点検口の提供を目的とする。【解決手段】天井１に開設された開口部２内に固定される外枠３に対して閉塞回転位置と開放回転位置との間で回動自在に内枠４を連結した点検口本体５と、前記閉塞位置に内枠４を拘束する閉塞操作位置と拘束解除する開放操作位置との間で移動自在に点検口本体５に取り付けられるロック体６とを有し、前記点検口本体５とロック体６のいずれか一方には、ロック体６が開放操作位置をとるときに外部から目視容易で、閉塞操作位置をとるときに目視不能、あるいは目視困難になるロック判別部７を形成して構成する。【選択図】図１
