FIXING STRUCTURE FOR CEILING INSPECTION DOOR
PROBLEM TO BE SOLVED: To hinder visual recognition of a portion where an inspection door is engaged to a ceiling, when seen from a ceiling surface side.SOLUTION: An inspection cover 4 fitted on an inspection port 3 on a ceiling from a rear side of the ceiling is fixed on an edge part of the inspection port 3 using a fixture 5, for preventing lifting of the inspection cover 4. A standing piece 3a and a support part 3b are formed on an outer edge piece 4d of the inspection port 3. The inspection cover 4 has an insertion hole 10 formed near an outer edge. The fixture 5 includes an operating shaft member 11 inserted into the insertion hole 10, and an engaging body 12 fitted on the operating shaft member 11 inserted into the insertion hole 10, on a rear surface of the inspection cover 4. The engaging body 12 includes a latch part 24 engaged to the standing piece 3a of a ceiling panel 2. The latch part 24 is U-shaped, and sandwiches the outer edge piece 4d of the inspection cover 4 and the support part 3b of the standing piece 3a, while the outer edge piece 4d of the inspection cover 4 and the support part 3b of the standing piece 3a are overlapped.SELECTED DRAWING: Figure 1
【課題】点検蓋を天井に係止する部位が天井の表面側から見て視認されることを抑える。【解決手段】天井の点検口３に対して天井裏側から嵌合された点検蓋４を固定具５によって点検口３の縁部に固定して、点検蓋４の浮き上がりを防止する。点検口３の外縁片４ｄには、起立片３ａと支持部３ｂが形成されている。点検蓋４は、外縁近傍に挿通孔１０が形成されている。固定具５は、挿通孔１０に挿通される操作軸部材１１と、点検蓋４の裏面において挿通孔１０に挿通された操作軸部材１１に取り付けられる係止体１２とを備える。係止体１２は、天井パネル２の起立片３ａに係止される掛け金部２４が設けられている。掛け金部２４は、コ字状に形成されており、点検蓋４の外縁片４ｄと起立片３ａの支持部３ｂとが重なった状態において、点検蓋４の外縁片４ｄと起立片３ａの支持部３ｂとを挟み込む。【選択図】図１
