PROBLEM TO BE SOLVED: To solve the following problem in an emergency escape rope ladder: (a) it requires time for converting into an useable state; (b) non-skilled person cannot use it; (c) it requires power, thus it cannot be established for a powerless lady or child, or a person who does not have toughness; (d) it cannot be fixed, and it swings and is curved, thus a non-skilled person cannot use it; (e) it has a difficulty in transfer from a window, balcony, and to solve the following problem in an emergency escape fixed steps: (a) there is a risk in crime prevention; (b) there is a risk in an accident due to an infant or child uses it as a play equipment; (c) there is a risk in crime prevention when it communicates flours.SOLUTION: They are solved by arranging movable steps (3). Upon emergency, it may be used by only releasing the steps (3). When the movable steps (3) are developed (figure 1), it exerts an efficiency equivalent to that of the fixed steps. Upon normal situation, the movable steps are upwardly withdrawn (figure 2) and only props are left at a lower part so that no man rises it. A prop (1) is arranged for converting it into complete fixed steps so as to prevent swing. A rope (5) is release so that it is developed from a stored mode (figure 1) to a use mode (figure 2) at a moment.
【課題】 非常脱出用縄梯子は（イ）使用状態にするのに時間を要しする。（ロ）訓練をしていない人には、使用出来ない。（ハ）力が必要で非力な子女や体力のない人には設置できない。（ニ）固定されず、ふらつき、屈曲するので訓練をしないと使用できない。（ホ）窓、ベランダよりの乗り移りが難しい。非常脱出用固定梯子は（イ）防犯上の問題がある。（ロ）幼児、児童の遊具とされ事故の危険がある。（ハ）階で繋ぐと、防犯上問題がある。【解決手段】 可動踏み桟（３）を設け、解決した。非常時は、踏み桟（３）の開放だけで、使用可能にした。可動踏み桟（３）を展開し［図１］、固定梯子と同等の性能とした。通常は、可動踏み桟を上部に引き上げ［図２］下部を支柱だけにし、昇降できなくした。支柱（１）を設け、完全な固定梯子とし、揺れを防止した。ロープ（５）を開放し、瞬時に格納状態［図１］より使用状態［図２］に展開する。
