Abstract

PROBLEM TO BE SOLVED: To prevent overturning of a stepladder and safely perform high lift work by providing a frame of a leg of a stepladder with a clamp bar where a clamp of a scaffolding pipe is mounted, and fixing it to the scaffolding pipe driven in the ground. SOLUTION: A clamp bar 2 for mounting a clamp of a scaffolding pipe on a frame 1 of a leg of a stepladder is movably fitted by a bolt 3, whereby the clamp can be fixed to an arbitrary position of the frame 1. First, a scaffolding pipe is driven into the ground, secondary, the clamp is fitted through the clamp bar 2, and the stepladder is fixed to the scaffolding pipe to be stably held without overturning. Agricultural works for fruit tree or the like, car washing or high lift work can be safely conducted on the top plate 6 in cooperation with a handrail part 7 and a wide top plate 6.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a stepladder which works on an orchard and a tabletop and can be temporarily fixed so that the stepladder does not fall down.

[0002]

2. Description of the Related Art A stepladder for working on an orchard and a top plate (6) does not have a device for easily and stably holding the stepladder.

[0003]

SUMMARY OF THE INVENTION It is necessary to fix the stepladder so that it is easy to work.

[0004]

It is sufficient to provide a fixing device which does not fall down on a stepladder.

[0005]

Operation and Embodiment FIG. 1 is a perspective view of a stepladder. When the stepladder is to be fixed, the scaffold pipe (5) is driven into the site and fixed, the clamp (4) for the scaffold is attached to the clamp bar (2), and the scaffold pipe is fixed with a clamp to prevent the stepladder from falling. . Further, it is easy to loosen or remove the bolt (3) of the clamp bar and to reattach it to an arbitrary position of the frame.

Although the frame (1) is a square pipe in the figure, by making this frame the same thickness as the scaffold pipe,
It is possible to mount the clamp directly.

FIG. 2 is a perspective view of a stepladder fixed to a scaffold pipe. The scaffold pipe (5) is driven into the soil, a clamp is attached via the clamp bar (2), and the stepladder is fixed to stabilize. The dotted pipe (5a) is a scaffold pipe driven into the soil.

[0008]

The material may be aluminum, which is lightweight. There are handrails (7) for agricultural work such as fruit trees, car washing, and high-place work, and the work is good because it is on a wide top plate (6). Doing so became a stepladder with a sense of stability.

Claims (2)

[Claims] 1. A leg frame (1) comprising a clamp bar (2) for attaching a clamp of a scaffold pipe to a stepladder and a bolt (3) for freely adjusting the height of the clamp bar.
A stepladder, which is a mechanism for attaching a clamp (4) for securing the stepladder to a stable position without falling down. 2. The stepladder according to claim 1, wherein the frame of the stepladder of FIG. 1 is a square pipe, which is made of a round pipe having a diameter compatible with the clamp, that is, the same diameter as the scaffold pipe.
