【考案の詳細な説明】 本案は地震、火災等の緊急事態発生時に使用す
る避難梯子に関する。[Detailed description of the invention] This invention relates to an evacuation ladder to be used in the event of an emergency such as an earthquake or fire.

２階以上の建物で地震、火災等の発生時の緊急
避難用に避難梯子を備える場合が多い。 Buildings with two or more floors are often equipped with evacuation ladders for emergency evacuation in the event of an earthquake, fire, etc.

この種避難梯子は平常時はほとんど使用するも

ための場所の確保と関連して特別な建物の設計施
工を要し建設費の高騰を来す。そこで一般には安
価に設置できる伸縮梯子類が使用される。ところ
で従来よりこの種避難梯子として上端を窓枠部等
に掛止して伸展を計り、建物壁面に添わせる形で
使用する構成のものが提案されている。 This type of escape ladder is rarely used during normal times, so if it were to be attached to a building, it would require a special building design and construction to secure space for it, which would lead to high construction costs. Therefore, telescopic ladders, which can be installed inexpensively, are generally used. However, a ladder with an upper end that is attached to a window frame or the like and extended so that it can be attached to the wall of a building has been proposed.

これ等の梯子は、そのほとんどが直線的に伸縮
し、使用時には壁面にくつついた状態になるとこ
ろから、高所に於いて窓の外にこれを見下すとき
恐怖感を覚えるものであり、更にこの梯子に乗り
移つて避難行動に入るのにも戸惑いを生じ緊急避
難の円滑性を欠き、また仮令梯子に乗り移つたと
しても、ステツプに足を掛けるとステツプが壁側
に押し付けられるようになつて、壁面との隙間が
なくなり、下段のステツプへ足を掛け変えるのが
むづかしくなり、この面からも行動の迅速性を欠
く等の欠点がある。 Most of these ladders extend and contract in a straight line, and when they are used, they are attached to the wall, which creates a sense of fear when looking down from a window from a high place. It is confusing to move onto this ladder and begin evacuation operations, which makes emergency evacuation less smooth.Also, even if you move onto the temporary ladder, when you put your foot on the step, the step becomes pressed against the wall. As a result, there is no gap with the wall surface, making it difficult to put your feet on the lower step, and this also has disadvantages such as a lack of swiftness of action.

本案は上記の如き欠点を一掃すべくなされたも
のであつて、窓枠部等に上端を掛止させ伸展させ
た状態で、その全体が自然に前方、即ち建物側か
ら離れる方向に張出するようになり何人も恐怖感
をなくして使用でき、また揺動も少なくステツプ
に対する足掛けも簡単な避難梯子を提供しようと
するものである。 This proposal was made to eliminate the above-mentioned drawbacks, and when the upper end is hung on the window frame etc. and extended, the entire structure naturally extends forward, that is, in the direction away from the building side. The purpose of the present invention is to provide an evacuation ladder that can be used by any number of people without fear, has less shaking, and has easy footholds on the steps.

以下本案を図面について説明する。 The present invention will be explained below with reference to the drawings.

１，２は左右一対の側杆、３はこの側杆１，２
の下端に形設したステツプ、４は側杆１，２の上
端部で側杆前方に向け突出状に設けた環体であ
る。左右側杆１，２の各環体４には上位側杆１，
２を順次に緩挿し、所要長さに伸展する伸縮自在
とした梯子Ａを構成する。 1 and 2 are a pair of left and right side rods, 3 is this side rod 1 and 2
A step 4 formed at the lower end of the frame is a ring body provided at the upper end of the side bars 1 and 2 so as to protrude toward the front of the side bars. Each ring body 4 of the left and right side rods 1 and 2 has an upper side rod 1,
2 are sequentially inserted slowly to form a telescopic ladder A that can be extended to a required length.

本案においては側杆１，２の下端部に於いてス
テツプ取着点に近接して前方に向け緩い角度で屈
曲させた屈曲部５を形成すると共に、これに対応

成する。然して梯子Ａは伸長状態で環体４が上位
側杆１，２を降下して、ステツプ３に当接し、ま
た側杆１，２の環体上方に延びる突出端６は上位
側杆１，２の屈曲部５に於いて、その後面に添接
するところから梯子Ａは全体として伸展状態で各
段毎に上位側杆１，２に対しその前方に張出す様
に角度が付けられる。 In this case, a bent part 5 is formed at the lower end of the side bars 1 and 2 in the vicinity of the step attachment point and bent forward at a gentle angle, and correspondingly, the upper end of the side bar is formed with a ring. A protruding end 6 is formed that extends upward from the body. When the ladder A is in an extended state, the ring body 4 descends the upper side bars 1 and 2 and comes into contact with the step 3, and the protruding ends 6 of the side bars 1 and 2 extending above the ring body are attached to the upper side bars 1 and 2. At the bent portion 5 of the ladder A, from where it is attached to the rear surface, the ladder A as a whole is in an extended state and is angled so that each rung extends forward from the upper side bars 1 and 2.

従つて、本案は最上位側杆１，２に吊下げ金具
７を設け、これを窓枠等に引掛けて建物外に伸展
させると梯子Ａの下部は建物の壁面から離れて外
方に張出すようになり、地上或いはその近傍まで
到達する。 Therefore, in this case, the hanging fittings 7 are installed on the uppermost side bars 1 and 2, and when these are hooked onto a window frame or the like and extended outside the building, the lower part of the ladder A is separated from the wall of the building and stretched outward. It begins to emit light and reaches the ground or its vicinity.

そこで、この梯子Ａの上端部の所で梯子Ａを見
下すとき従来のこの種伸縮梯子の如く建物壁面に
くつついた様に真直すぐに伸展するものに比べ不
安感、恐怖感がなく、何人も直ちに避難行動に入

梯子Ａに体重を掛けると上位側杆１，２の屈曲部

出端６の相互添接関係が堅固なものとなり、ふら

きると共に建物壁面との間には隙間が確保されて
ステツプ３に対する足掛けにも何の支障もなく緊
急の避難梯子として多くの実用的効果を奏するも
のである。 Therefore, when looking down at Ladder A from the top end of Ladder A, there is no sense of anxiety or fear compared to conventional telescopic ladders of this kind, which extend straight and quickly as if attached to the wall of a building. I was able to take immediate evacuation action and was able to move onto ladder A.
When you put your weight on the ladder A, the mutual connection between the bent portions 5 of the upper rods 1 and 2 and the protruding ends 6 extending above the rings of the lower rods 1 and 2 becomes firm, and there is no wobbling or the like and it is safe. In addition to being able to quickly descend from the ladder, a gap is secured between the ladder and the building wall, and there is no problem in stepping onto the step 3, and it has many practical effects as an emergency evacuation ladder.
