閉塞しである。A general evacuation device of this type is provided with an evacuation ladder in a hole that passes through the upper and lower floors, which is folded up and stored in the hole when not in use, and which extends and descends to the floor directly below when in use. The opening is closed with a lid (upper lid) that can be opened and closed.
ところが、従来のこの種避難装置においては、避難梯子
へ誘導するための手段が施されているものが少なく、そ
のため、火災等の非常時において、下階へ避難する場合
に、孔部の縁に手を掛けるなどして避難梯子に乗り移っ
ている。However, few of the conventional evacuation devices of this type are equipped with a means to guide the person to the evacuation ladder, and as a result, in the event of an emergency such as a fire, when evacuating to the lower floor, the edge of the hole cannot be used. They are trying to get onto the evacuation ladder by holding onto their hands.
しかし、このように身を屈めて床部に手を置くという姿
勢は極めて不安定であって、恐怖心を生じさせ、特に婦
女子等が避難する場合には危険が伴ない、二次災害を惹
起するという問題がある。However, this posture of bending over and placing one's hands on the floor is extremely unstable and creates fear, which is especially dangerous for women and girls evacuating, and can lead to secondary disasters. There is a problem with doing so.
よって、現状ではこの点の安全対策が望まれている。Therefore, safety measures in this regard are currently desired.

を向上させる必要があった。In addition, as a guide means to the evacuation ladder described above, there are devices in which a handhold frame is provided integrally with the back surface of the top cover or via a link mechanism connected to the top cover, but in these cases, the above-mentioned handhold frame is provided. When an evacuee grasps the handhold frame and climbs onto the evacuation ladder, a considerable load is applied to the handhold frame, so the strength of the top cover is improved by increasing the plate thickness of the top cover that supports this handhold frame. There was a need.
しかし上蓋の板厚を厚くすることは、コストの上昇につ
ながるばかりでなく、ひいては上蓋の重量が重くなり非
常時の迅速な操作に支障を来たす欠点を有するものであ
った。However, increasing the thickness of the top cover not only increases the cost, but also increases the weight of the top cover, which has the disadvantage of hindering quick operation in an emergency.
この考案は、上記事情にかんがみなされたもので、避難
梯子を下階へ伸張降下する上蓋の開放とほとんど同時に
開放する下蓋の開放動作に伴なってリンク機構を介して
