Description
【０００１】[0001]
この考案は、天井裏部屋へ登り降りする時に利用する、折りたたみ階段に関する ものである。 The present invention relates to a folding staircase to be used when climbing up and down the ceiling room.
【０００２】[0002]
従来、ハシゴ段の収縮式のがあるが、使用上、人体の姿勢のバランスが不安定で 危険である。 Conventionally, there is a ladder type contraction type, but it is dangerous because the balance of the posture of the human body is unstable in use.
【０００３】[0003]
これは次のような欠点があった。 （イ）足で踏む面積が小さく、昇降時に人体の姿勢が不安定である。 （ロ）けこみ板と踏み板が無いため、床が真下に見えて不安感が生じる。 本考案は、これらの欠点を除くためになされたものである。 This had the following drawbacks. (A) The area of stepping on it with a foot is small, and the posture of the human body is unstable when going up and down. (B) Since there is no entry board or tread board, the floor looks directly below, causing anxiety. The present invention has been made to eliminate these drawbacks.

サイドフレーム（１１）に、アーム（２）アーム（７）を固定回転軸（１）固定 回転軸（８）で接続し、さらに接続アーム（５）をアーム（２）アーム（７）に 回転軸（４）回転軸（６）によって連結する。けこみ板（１４）と踏み板（１３ ）を蝶板（１２）によって連結し、サイドフレーム（１１）の縦材と横材を蝶板 （１７）で連結する。天井板（１５）に軸受（１０）を設け、固定回転軸（９） をサイドフレーム（１１）に設ける。そして最下段のけこみ板（１４）に取手（ １６）を設ける。本考案は以上の構成によりなる折りたたみ階段。 The arm (2) and the arm (7) are fixed to the side frame (11) by the fixed rotary shaft (1) fixed rotary shaft (8), and the connecting arm (5) is further connected to the arm (2) arm (7). (4) Connect by the rotating shaft (6). The board (14) and the footboard (13) are connected by a butterfly board (12), and the vertical and horizontal members of the side frame (11) are connected by a butterfly board (17). A bearing (10) is provided on the ceiling plate (15), and a fixed rotating shaft (9) is provided on the side frame (11). Then, the handle (16) is provided on the lowermost indentation plate (14). The present invention is a folding staircase having the above configuration.
【０００５】[0005]
階段になった状態で、取手（１６）を前方へ押すと、アーム（７）と接続アーム （５）の作動でアーム（２）が固定支持軸（３）より上方へ離れ、フック解除に なり、踏み板（１３）が、けこみ板（１４）に重なるように近づく。次に取手（ １６）をさらに上方へ押し上げると、階段のすべてが同じ作動をくり返し収縮す る。最後にサイドフレーム（１１）に設けた固定回転軸（９）を中心に、収縮し た階段が半転して天井開口部より天井裏へ収まる。階段として使用する時は、取 手（１６）を下方へ引きおろし、最下段が床に着くとそのまま使用する。 When the handle (16) is pushed forward in the staircase, the arm (7) and the connecting arm (5) are actuated to move the arm (2) upward from the fixed support shaft (3), and the hook is released. , The footboard (13) approaches so as to overlap the embossing board (14). The handle (16) is then pushed further upwards, causing all of the steps to repeat the same action and contract. Finally, the contracted staircase half-turns around the fixed rotating shaft (9) provided on the side frame (11) and fits under the ceiling through the ceiling opening. When using it as a stair, pull down the handle (16) and use it when the bottom reaches the floor.
【０００６】[0006]
以下、本考案の実施例について説明する。 （イ）サイドフレーム（１１）に、アーム（２）アーム（７）を固定回転軸（１ ）固定回転軸（８）で接続する。 （ロ）接続アーム（５）を、アーム（２）アーム（７）に回転軸（４）回転軸（ ６）によって連結する。 （ハ）けこみ板（１４）と踏み板（１３）を、蝶板（１２）によって連結する。 （ニ）蝶板（１７）で、サイドフレーム（１１）の縦材と横材を後ろ側で連結し 、以上の機構を階段の各段に設ける。 （ホ）天井板（１５）に軸受（１０）を設け、固定回転軸（９）をサイドフレー ム（１１）に設ける。 （ヘ）最下段のけこみ板（１４）に取手（１６）を設ける。本案は以上のような 構造で、これを使用するときは、図４で示すように天井裏へ収納された状態の取 手（１６）を回転軸（９）を中心に半転させて下方へひくと、自重によりアコー デオンのように下へのびてきて、アーム（７）接続アーム（５）が回転軸（６） を中心に次第に角度を拡げて、アーム（２）をサイドフレーム（１１）に固定さ れた固定支持軸（３）にフックするように導く。以上の作動が各段に連動して、 最下段が床に着くと階段としての構造上の強度ができ使用できる。逆に階段を天 井裏へ収納する時は、取手（１６）を前方へ押すと、３図で示すようにアーム（ ７）と接続アーム（５）が作動し、ア一ム（２）が固定支持軸（３）より上方へ 離れ、フック解除になり、踏み板（１３）が、けこみ板（１４）に重なるように 近づく、さらに取手（１６）を上方へ押し上げると、階段のすべてが同じ作動を くり返し収縮する。最後にサイドフレーム（１１）に設けた固定回転軸（９）を 中心に、収縮した階段が半転して図４に示すように天井開口部より天井裏へ収ま る。 Embodiments of the present invention will be described below. (A) The arm (2) and the arm (7) are connected to the side frame (11) by the fixed rotary shaft (1) and the fixed rotary shaft (8). (B) The connecting arm (5) is connected to the arm (2) and the arm (7) by the rotating shaft (4) and the rotating shaft (6). (C) The entry board (14) and the step board (13) are connected by the butterfly board (12). (D) With the butterfly plate (17), the vertical members and the horizontal members of the side frame (11) are connected at the rear side, and the above mechanism is provided at each step of the stairs. (E) A bearing (10) is provided on the ceiling plate (15), and a fixed rotating shaft (9) is provided on the side frame (11). (F) A handle (16) is provided on the bottom panel (14). This proposal has the structure as described above. When using this, the handle (16) stored in the ceiling as shown in Fig. 4 is rotated halfway around the rotating shaft (9) and moved downward. When it is pulled, it extends downward like an accordion due to its own weight, and the connecting arm (5) of the arm (7) gradually expands its angle around the rotation axis (6), and the arm (2) is extended to the side frame (11). Guide it so that it hooks onto the fixed support shaft (3) fixed to. The above operation is linked to each step, and when the bottom step reaches the floor, it can be used because it has structural strength as a staircase. On the other hand, when the stairs are stowed in the back of the roof, pushing the handle (16) forward activates the arm (7) and the connecting arm (5) as shown in Fig. 3, and the arm (2) moves. The stairs (13) move up above the fixed support shaft (3) and the hooks are released, and the tread (13) approaches the stacking plate (14). The operation is repeatedly contracted. Finally, the contracted staircase half-turns around the fixed rotating shaft (9) provided on the side frame (11) and fits under the ceiling from the ceiling opening as shown in FIG.
【０００７】[0007]
天井裏空間を利用する際、階段室スペースがいらず、しかも安全に使用できる。 When using the space above the ceiling, there is no need for staircase space, and it can be used safely.
