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 inspection opening on a high ceiling.SOLUTION: An inspection port opening/closing device 1 has an opening/closing tool unit 3 that is detachably connected to the front end in the extending direction of an operation rod 2. The inspection port opening/closing device 1 is configured so as to, when carrying out a closing work of a door 100 of an inspection port 201a, hold a state that the door 100 of the inspection port 201a is held between a roller 13 and a hook member 15 of the opening/closing tool unit 3. In this state, by performing an operation to raise an operation rod 2, the door 100 of the inspection port 201a is closed.SELECTED DRAWING: Figure 1
【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】点検口開閉具１は、操作棒２の延出方向の先端に着脱可能に連結される開閉具ユニット３を有する。点検口開閉具１では、点検口２０１ａの扉１００を閉める作業時に、開閉具ユニット３のローラ１３と引掛け部材１５との間で点検口２０１ａの扉１００を挟持した状態を維持したままで保持する。この状態で、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１
