INSPECTION PORT OPENING/CLOSING DEVICE
To provide an inspection port opening/closing device applicable to a work at height capable of allowing a user to safely carry out opening/closing work of a door of inspection opening on a high ceiling.SOLUTION: The inspection port opening/closing device is configured so as to, when carrying out an opening/closing work of a door 100 of an inspection port 201a, hold a state that the door 100 is held between a fist engaging member 13 of a door receiving member 4 of the opening/closing tool unit 3 and engaging ends 15a and 16a of a second engaging member of the door holding member 5. In this state, by raising an operation rod 2 while supporting the door 100 from the bottom, the door 100 of the inspection port 201a is closed.SELECTED DRAWING: Figure 2
【課題】高所作業用に適用することができ、高所の天井の点検口の扉の開閉作業を安全に行うことができる点検口開閉具を提供する。【解決手段】点検口２０１ａの扉１００を開閉する作業時には、開閉具ユニット３の扉受け部材４の第１係合部材１３と、扉把持部材５の第２係合部材の係合端部１５ａ、１６ａとの間で扉１００を把持した状態を維持したままで保持する。この状態で、扉１００を下から支えながら操作棒２を上昇させる操作により、点検口２０１ａの扉１００を閉める作業を行うことができる。【選択図】 図２
