PROBLEM TO BE SOLVED: To provide a fall prevention device of a door opening time which does not require careful installation operation and in which a handrail used when going down to a ladder can be installed to a door part in an open state.SOLUTION: A fall prevention device of a door opening time is applied, for example, to an elevator and comprises: a ladder 8 which is positioned on the outside of a landing door 2 that is openable/closable in a horizontal direction, disposed at a place such as a pit 1 which is located lower than a floor of a hall where the landing door 2 is installed, and used when getting off from the floor of the hall to a lower place when the landing door 2 opens; and a handrail 10 which is provided at the position of the ladder 8 so as to protrude upward from the floor of the hall and prevents a user of the ladder 8 from falling down to the pit 1 when the landing door 2 opens. The handrail 10 is provided liftably, and a through hole 3c into which the handrail 10 can be inserted is formed at a sill groove 3a of a door sill 3 for guiding the landing door 2. The device also comprises a lift control device for controlling the lifting of the handrail 10.
【課題】慎重な設置作業を要することなく、開状態にあるドア部分に梯子に降りる際に利用される手摺りを設置することができるドア開時の転落防止装置の提供。【解決手段】本発明に係るドア開時の転落防止装置は、例えばエレベータに適用させたものであり、左右方向に開閉可能な乗場ドア2の外側に位置し、乗場ドア2が設置される乗場の床面よりも低い箇所、例えばピット1に配置され、乗場ドア2の開時に乗場の床面から低い箇所に降りる際に利用される梯子8と、乗場の床面よりも上方に突出するように梯子8の位置に設けられ、乗場ドア2の開時に梯子8の利用者のピット1への転落を防止する手摺り10とを備えたものにあって、手摺り10を昇降可能に設け、乗場ドア2を案内する敷居3のシル溝3aに、手摺り10が挿通可能な貫通穴3cを形成し、手摺り10の昇降を制御する昇降制御装置を備えている。【選択図】図1
