| description | To provide an inspection port capable of improving crime prevention with a simple mechanism.SOLUTION: A ceiling inspection port 1 includes an outer frame 2 arranged on the inner peripheral edge of an opening O, and an inner frame 3 openably/closably arranged inside the outer frame 2. The ceiling inspection port 1 further includes an engagement member 5 provided on the inner frame 3, and a locking plate spring 6 that is provided on the outer frame 2, and prevents opening to the outer frame 2 of the inner frame 3 by being engaged with the engagement member 5. A notch 24 to which an unlocking tool R can be inserted is formed between the inner frame 3 and the outer frame 2. The locking plate spring 6 has a receiving part 66 for receiving the unlocking tool R inserted to the notch 24. The locking plate spring 6 is bent and deformed by operation of the unlocking tool R received in the receiving part 66, and thereby engagement with the engagement member 5 is released.SELECTED DRAWING: Figure 7
【課題】簡素な機構で防犯性を向上させ得る点検口を提供する。【解決手段】開口部Ｏの内周縁に配置される外枠２と、外枠２の内側で開閉自在に配置される内枠３とを備える天井点検口１である。天井点検口１は、内枠３に設けられた係合部材５と、外枠２に設けられて係合部材５に係合することで内枠３の外枠２に対する開きを防止する施錠板ばね６とをさらに備える。内枠３と外枠２との間に、開錠具Ｒが挿入され得る切欠き２４が形成される。施錠板ばね６は、切欠き２４に挿入された開錠具Ｒを受ける受部６６を有する。施錠板ばね６は、受部６６で受けられた開錠具Ｒの操作により曲げ変形することで、係合部材５との係合が解除される。【選択図】図７ |
