FALL PREVENTION MEMBER FOR INSPECTION PANEL AND INSPECTION PORT DEVICE INCLUDING THE SAME
To make it easy to remove an inspection panel and prevent it from falling as well.SOLUTION: An inspection panel fall prevention member 1 includes: a panel side fixing portion 2 attached to a back surface of an inspection panel; a skeleton side fixing portion 3 attached to a predetermined fixed object around an inspection port; and a main body portion 4 connecting the skeleton side fixing portion 3 and the panel side fixing portion 2. The main body portion 4 integrally includes: a first shock absorbing portion 11; a second shock absorbing portion 13; a first linear portion 12 provided between both shock absorbing portions 11 and 13; and a second linear portion 14 provided between the second shock absorbing portion 13 and the skeleton side fixing portion 3. The first and second linear portions 12 and 14 have a shape closer to a straight line than the first and second shock absorbing portions 11 and 13 in a natural state, and the first and second shock absorbing portions 11 and 13 have constant bent shapes in the natural state, and can be deformed in a direction to release the bent as well, when a tensile force corresponding to its own weight of the inspection panel is applied.SELECTED DRAWING: Figure 3
【課題】点検パネルを取り外す際の扱い易さと点検パネルの落下防止とを両立する。【解決手段】点検パネル用落下防止部材１は、点検パネルの裏面に取り付けられるパネル側固定部２と、点検口周りの所定の固定物に取り付けられる躯体側固定部３と、躯体側固定部３とパネル側固定部２とを連結する本体部４とを備える。本体部４は、第１衝撃吸収部１１と、第２衝撃吸収部１３と、両衝撃吸収部１１，１３の間に設けられた第１線形部１２と、第２衝撃吸収部１３と躯体側固定部３との間に設けられた第２線形部１４とを一体に有している。第１・第２線形部１２，１４は、自然状態において第１・第２衝撃吸収部１１，１３よりも直線に近い形状を有し、第１・第２衝撃吸収部１１，１３は、自然状態では一定の屈曲した形状を有するとともに点検パネルの自重に相当する引張力が作用したときには当該屈曲を解除する方向に変形可能である。【選択図】図３
