Due to such factors, the knees had to be turned outward and the feet had to be turned sideways. In addition, when working, it is stable if the user straddles the top of the stepladder, but the body is difficult to support and unstable in the middle stage. Furthermore, it is difficult to install the device facing the object. There were inconveniences such as.

スや運搬コストが大幅に低減される効果がある。A folding stepladder 10 shown in FIG. 1 shows a state in which two ladder-like frames 12 are opened in a V-shape around a connecting portion and stand up. The side ends of the frame 12 are connected to each other by a connecting member 14, and are held at an appropriate angle so that the stepladder 10 does not fall over and is easily moved up and down. Each frame 12 has two vertical stiles 1
8 and five steps 16 arranged at equal intervals, and the frame 12 is foldably connected to each other by three hinges 20. The lower end portion 22 of each vertical frame 18 in contact with the ground functions as a leg, but in this example, four vertical frames 18
Of these, the two vertical frames 18 on the side to which the frame 12 is connected function as one leg, and the stepladder 10 is substantially erected by three legs. FIG. 2 shows a state where the stepladder 10 is folded and stored. This has the effect of significantly reducing storage space and transportation costs.

降りにも、脛や膝が踏段１６に当たることはない。Normally, when looking at the footprint of a person's natural body, the toes are located outward and open. In other words, it can be seen that the footprint is V-shaped. Also, when bending the knee, it is easy to bend outward. On the other hand, according to the stepladder 10 of the present invention, as shown in FIG.
Since it is arranged in a letter shape, it fits well with the characteristics of the foot described above. In other words, when the step is stepped on, the long side of the step 16 and the long side of the footprint are substantially parallel, so that the step 1
Even if the width of 6 is narrow, the sole of the foot does not hurt. In addition, the shin or the knee does not hit the step 16 when going up and down.

る。Further, workability is improved as follows. In other words, the worker can straddle the connecting portion 24 and support the body with both knees, so that the worker can work stably at the step position according to the height. In addition, it is possible to install and face the work object. And so on.

保管や運搬に便利である。The ladder according to the present invention has a triangular prism shape in which long rectangular frames 12 are connected in a V-shape with their long sides aligned. It leans on the connecting part obliquely and uses it like a normal ladder. As in the case of a stepladder, the sole of the foot can be hurt and the shin or knee can be moved up and down without hitting the steps. In particular, if they are foldably connected,
Convenient for storage and transportation.
