FALL PREVENTION DEVICE OF WATERPROOF PLATE
PROBLEM TO BE SOLVED: To provide a fall prevention device of a waterproof plate having both durability and readiness.SOLUTION: A locking body 29 is rotatably installed so that upper-lower end parts approach and separate to a waterproof plate opposed surface in a guide groove of a guide rail 2. Upper-lower receiving parts 30a and 30b vertical provided at an interval, are provided in a place of the guide rail 2 positioned on the lower side than the locking body 29. The locking body 29 comprises an abutting part 29c capable of abutting on at least the upper receiving part 30a by descent of the waterproof plate. When the waterproof plate descends by normal operation, the abutting part 29c abuts on the upper receiving part 30a, and returns to an original attitude by dead weight of the locking body 29 after rotating the locking body 29. When the waterproof plate falls, before returning to the waterproof plate side of its lower part by the dead weight of the locking body 29, the lower end of the locking body 29 is locked on the lower receiving part 30b, and a fall of the waterproof plate is prevented. A swing prevention member such as a magnet 35 is provided for preventing swinging of the locking body 29.
【課題】耐久性と即応性を兼ね備えた防水板の落下防止装置に提供する。【解決手段】ガイドレール２のガイド溝内の防水板対向面に対して、上下端部が近接、離反するように回動可能に係止体２９を取付ける。係止体２９より下側に位置するガイドレール２の箇所に、上下に間隔を有して設けられた上下の受け部３０ａ，３０ｂを備える。係止体２９は、防水板の降下により、少なくとも上方の受け部３０ａに当接可能な当接部２９ｃを有する。通常操作による防水板の降下の際には、当接部２９ｃが上方の受け部３０ａに当接して係止体２９を回動させたのち、係止体２９の自重により原姿勢に復帰する。防水板の落下の際には、係止体２９の自重によるその下部の防水板側への復帰の前に係止体２９の下端が下方の受け部３０ｂに係止されて防水板の落下が防止される。係止体２９の揺れを防止する磁石３５等の揺れ防止部材を設ける。【選択図】図６
