【考案が解決しようとする課題】
縄ばしごが壁面に近過ぎると足の裏で桟を踏み外さない様にしたい。
【課題を解決するための手段】
従来の縄ばしごを簡単に安全に窓枠敷居部分に取り付け易く別紙図の様に安全に脱出体勢に入れる様別紙図の様に考案、縄ばしごの桟に足のつま先が安全に掛かる様壁面から間隔が空く様に足掛け桟の両端に円盤を取り付けた。
【考案実施の形態】
災害時火災発生時縄ばしごを使い二階の窓．三階の窓から脱出する訓練をするについて、非難用縄ばしごの使い易い窓、使い難い窓が有る。
【非難用縄ばしごを使い易い窓】
１．窓枠の大きさは引き戸又は開き窓を全開にした状態で開口部の寸法が、縦９０ｃｍ横８０ｃｍ以上有ること。
２．敷居及び壁の厚さが２５ｃｍ位の厚さが有り窓枠から下は壁の場所が望ましい。
３．以上１．２．の条件下、予め脱出用窓の場所を決めて置く方が良い。
【非難用縄ばしごを使い難い窓】
１．窓枠の下に軒庇のある場所は避けるべき。
２．脱出する二階の窓の真下に開口部や窓がある場所は避け脱出用窓には窓下壁面に縄ばしごを垂らす時地面迄の間に障害物突起物がある所。
３．窓枠が９０ｃｍ×９０ｃｍ以下の窓枠。
４．室内床面から窓枠敷居までの高さが高すぎる窓は本考案本体を設置し難い。
【通常時 平素本考案の脱出用縄ばしごの収納状態】
本考案の脱出用縄ばしごは本考案の本体部分の内側に巻きたたみ収納する収納箱は脱出時本考案の脱出用縄ばしごを取り出し窓枠に装着した後はそのまま脱出用足場として使う事ができる。また未使用収納時は、室内調度品として配置できる様に外観を家具調にしている。
【本考案の構造上の特徴】
本考案は日常昼間一家の所帯主または男手の居ない事が多い、女性やお年寄りでも取り出し容易に架設する事ができる様本体の使用材料はアルミを使用し脱出様縄ばしご全体の重量は強度計算を行いつつできる限り軽量化に留意した。

[Technical field to which the invention belongs]
An improved rope ladder.
[Prior art]
Conventional rope ladders are troublesome to install, take time to enter the escape position, and there is no gap between the rope of the rope ladder and the wall.
[Problems to be solved by the invention]
If the rope ladder is too close to the wall, you want to keep the foot from stepping off the sole.
[Means for Solving the Problems]
The conventional rope ladder can be easily and safely attached to the window frame sill, and it can be safely put in the escape position as shown in the attached drawing.It is devised as shown in the attached drawing, and the distance from the wall surface is such that the toes of the feet are safely hooked on the rope ladder bar. Disks were attached to both ends of the footrest as if empty.
[Embodiment]
Windows on the second floor using a rope ladder in the event of a fire in a disaster. About training to escape from the windows on the third floor, there are easy-to-use windows and hard-to-use windows for the evacuation rope ladder.
[Windows that are easy to use for blaming rope ladders]
1. The size of the window frame should be 90 cm long and 80 cm wide with the sliding door or casement window fully opened.
2. The thickness of the sill and the wall is about 25 cm, and the location of the wall is desirable below the window frame.
3. Above 1.2. It is better to determine the location of the escape window in advance under the conditions described above.
[Window that it is hard to use rope ladder for blame]
1. Avoid places with eaves under the window sill.
2. Avoid places where there are openings or windows directly under the window on the second floor to escape. The window for escape has obstacles between the ground and the rope when you hang a rope ladder on the wall under the window.
3. A window frame whose window frame is 90 cm x 90 cm or less.
4. It is difficult to install the main body of the present invention on a window whose height from the indoor floor to the window frame sill is too high.
[Usually normal storage condition of escape rope ladder of the present invention]
The escape rope ladder of the present invention can be folded and stored inside the main body part of the present invention. The escape box can be used as an escape scaffold after taking out the escape rope ladder of the present invention at the time of escape and mounting it on the window frame. Also, when not in use, the exterior is furnished so that it can be placed as indoor furniture.
[Structural features of the present invention]
In the present invention, there are many cases where there is no family owner or man's hand in the daytime, and women and the elderly can easily take out and erection.The material used for the main body is aluminum and the escape rope rope is strong. We paid attention to weight reduction as much as possible while performing calculations.
