在米脚立を立てる場所の接地面が平らでない場合例えば
階段上やイ１斜面では脚立を安定良く直立せしめること
ができない。[Detailed Description of the Invention] If the ground surface where the American stepladder is set up is not flat, for example on a staircase or on a slope, the stepladder cannot be stably stood upright.
本発明は、どんな所であっても常に脚立を直立状態に安

るものにして、一実施例を示す添付図面を参照にして詳
述すると次の通りである。The present invention relates to an improved stepladder with movable legs so that the stepladder can be stably erected in an upright position at any location. It is as follows.
脚立（二おける前後左右の脚棒（１）の１端にリンク体
（２）の一端を軸動する。One end of the link body (2) is pivoted to one end of the front, rear, left, and right leg rods (1) of the stepladder.
リンク体（２）の他端を前後左右のガイドパイプ（３）
備（５）に丈設した軸受片（６）に軸重する。Connect the other end of the link body (2) to the front, rear, left and right guide pipes (3)
The axle load is placed on the bearing piece (6) installed in the length of the shaft (5).

着した場合を示している。The drawing shows a channel-shaped bearing frame a at the lower end of the holding rod (1).
υ is attached, and a link body (
2), one end of which is pivoted, and the other part of the link body (2) is pivoted to bearing pieces (6) protruding from the left and right guide pipes L3) (5).

片をそのまま軸受片（山にしている。The drawing shows the guide pipe +3+ (5) and the bearing piece (
6), the guide pipe 13+ (5) is not a circular pipe, but a U-shaped vibrator, and its extension pieces on both edges are used as bearing pieces (mountains).
またカム面（８）は円弧脚（７）に全面接面でさるよう
に下面を円弧脚（７）のパイプ径に合せた凹溝（８ｆに
形成している。Further, the cam surface (8) has a concave groove (8f) formed on the lower surface thereof so as to fit the entire surface of the arcuate leg (7) to the pipe diameter of the arcuate leg (7).
左右の脚棒間に架設した最下段の前後の横桟ＱＯ）の中
央部Ｔ−面にガイドパイプ（４）を付設し、この中央部
のガイドパイプ（４）と前記左右のガイドバイ、プとに
前後２本の円弧脚（７）をスライド自在に嵌挿する。A guide pipe (4) is attached to the center T-plane of the lowermost front and rear horizontal beam QO installed between the left and right leg bars, and the guide pipe (4) in the center is connected to the left and right guide pipes, The two front and rear arcuate legs (7) are slidably inserted into the .
狂米脚立は平地に直立させて使用するものとして設計さ
れているから４本の脚棒の長さは同じである。Since the Mad Rice Stepladder is designed to be used standing upright on level ground, the lengths of the four legs are the same.
このため手らでない朗例えは階段や傾斜面で使用しなけ
ればならない場合直立せしめることかできなかったり、
或いはガタガタ状態に立つことになり、不安定でその上
に登って作業することは危険了ら伴うことがあった。For this reason, a simple example is when you have to use it on stairs or slopes, you cannot stand it upright,
Otherwise, the person would have to stand in a shaky state, making it unstable and making it dangerous to climb on top of it.
本発明はこのような欠点を解決したもので、上述のよう
に構成したから例えは階段上で使用する場合脚立を持ち
上げるとリンク体（２）は円弧脚（７）の目正により回
動してリンク体（２１のカム面（８Ｊは円弧脚（７）の
上面より僅か（二離反し、円弧脚（７）は全くフリーに
スライドし得る状態になる。The present invention solves these drawbacks, and since it is configured as described above, for example, when the stepladder is used on stairs, when the stepladder is lifted up, the link body (2) rotates according to the adjustment of the arc leg (7). The cam surface (8J) of the link body (21) is slightly separated from the upper surface of the arcuate leg (7), and the arcuate leg (7) is in a state where it can slide completely freely.
このフリーの状態で脚立を階段上にのせて円弧脚（力を
接地させ、１つ脚立の自重がかからないように保持した
まま脚立が直立するように動かせはＨ弧胆（力はスライ
ド目在の状態であるから前後左右両端の脚が全部接地し
たままで脚立は直立状態Ｃ二是正され、階段上でも傾斜
面でも脚立は平地同様直立に設置できることになる。In this free state, place the stepladder on the stairs, apply force to the ground, and move the stepladder so that it stands upright while holding it so that the weight of the stepladder is not applied. Therefore, the stepladder is corrected to the upright state C2 with all the front, rear, left and right legs remaining in contact with the ground, and the stepladder can be installed upright on stairs or on slopes as well as on flat ground.
この直立状態になったとぎ脚立を離せは脚立の自重によ
りリンク体（２）が（９）動じ、そのカム・面（８）が
円弧脚（７）の上面に：圧接するから円弧脚（７）は不
動となり、脚立は安定良く直立し糊ることになる。When the stepladder is in an upright position, when it is released, the link body (2) moves (9) due to the stepladder's own weight, and its cam/surface (8) comes into pressure contact with the top surface of the arcuate leg (7). ) becomes immobile, and the stepladder stands upright and stable.
この際作業者が脚立に′登れば作業者の体重が更に付加
されるからそれだけカム面（８）の圧接力も強くなり、
円弧脚（刀は一層確固に固定されるでとになる。At this time, if the worker climbs onto the stepladder, the worker's weight will be further added, so the pressure contact force of the cam surface (8) will become stronger.
Arc leg (the sword is fixed even more firmly at the edge).
このカム面（８）の圧接はリンク体（２）の回動作用に
より行うから単にカイトバイブ（３バ５）に突設した軸
受片（６）と脚棒（１）の下端との間にリンク体（２）
を設けるたけで良く、その構成もｆ’ｓ単にして、製作
も容易するたけで良く、極めてその操作が容易となる。Since this cam surface (8) is pressed by the rotation of the link body (2), it is simply placed between the bearing piece (6) protruding from the kite vibe (3 bars 5) and the lower end of the leg rod (1). Link body (2)
It suffices to provide only f's, its structure is simple, and its manufacture is simple, making its operation extremely easy.

付脚立となる。In addition, the four leg rods of the stepladder (IJ is connected via the solitary leg (7), but just like on flat ground, all four legs are in contact with the ground, so it is stable without wobbling when used on flat ground. Since it can be installed horizontally, curved, or vertically, it is possible to climb up and work just like a stepladder set on flat ground.The more the worker's weight is lifted, the more difficult the stepladder becomes.
41 (71) becomes a 1" stepladder with movable legs that exhibits many excellent practicalities such as being able to be used stably at all times by keeping it fixed.
