CEILING INSPECTION PORT
To provide a ceiling inspection port advantageous for avoiding careless transition from a locked state to an unlocked state.SOLUTION: A ceiling inspection port 1 is provided with a locked part provided on an outer frame 20 and projecting toward an inner frame 60, and a locking tool 90 provided on the inner frame 60 and having a locking part 94 projecting toward the outer frame 20. The locking tool 90 is held by the inner frame 60 movably between a first position where the locking part 94 is positioned above the locked part in the vertical direction and a second position where the locking part 94 is not positioned above the locked part in the vertical direction. A first claw part 95 is engaged with a part of the locked part when the locking part 94 and the locked part are in contact with each other at the first position, and thereby enters a locked state that prevents the locking part 94 from moving from the first position to the second position; when the locking tool 90 is moved upward in the vertical direction, the engagement between the first claw part 95 and a part of the locked part is released, and the locking part 94 enters an unlocked state in which movement from the first position to the second position is possible.SELECTED DRAWING: Figure 12
【課題】不用意にロック状態からロック解除状態へと移行することを回避するのに有利な天井点検口を提供する。【解決手段】天井点検口１は、外枠２０に設けられ、内枠６０に向けて突出する被係止部と、内枠６０に設けられ、外枠２０に向けて突出する係止部９４を有する係止具９０とを備える。係止具９０は、被係止部の鉛直方向の上方に係止部９４が位置する第１位置と、被係止部の鉛直方向の上方に係止部９４が位置しない第２位置との間で移動可能に内枠６０に保持されている。第１爪部９５は、第１位置において係止部９４と被係止部とが接触しているときに被係止部の一部と係合することにより第１位置から第２位置への係止部９４の移動を妨げるロック状態となり、係止具９０が鉛直方向の上方に移動されることにより、第１爪部９５と被係止部の一部との係合が解除され、係止部９４の第１位置から第２位置への移動が可能であるロック解除状態となる。【選択図】図１２
