It is common to tie it with The present invention relates to a device for attaching this rail to a ladder, and is capable of attaching the rail regardless of the shape and dimensions of the main member of the ladder.

The drawings will be explained. The main body 1 consists of a rod receiving plate 1a and a front hanging plate 1b. The rod receiving plate 1a faces a presser plate 2, which will be described below, and can hold the foothold rod F from the left and right sides.
Has an arc-shaped recess in the center, and tightens bolts 3 on both ends.
There are holes drilled for it. The holding plate 2 is symmetrical to the rod receiving plate 1a. The front hanging plate 1b is fixed to the end of the rod receiving plate,
It is a rectangular body that projects horizontally from the rod receiving plate, and has a long hole 1c in the same direction in the center and a hole for the bolt 4 in the end. The U-shaped metal fittings 5 slidably sandwich the front hanging plate 1b at both bent leg sides. Further, a bolt hole is bored in the center of the bent base, and a bolt 6 passing through this hole and the elongated hole 1c is used to fix the bolt hole to the front hanging plate so that the position can be adjusted. The pair of clamp pieces 7, 7 can grip the top of the rail R at their ends, and are fixed to the ends of the front hanging plate by tightening bolts 4 at the center.

The base of the foothold rod F is sandwiched between the rod receiving plate and the holding plate, and fixed to the foothold rod with bolts 3. At this time, keep the axis of the front plate horizontal. Shift the position of the U-shaped metal fitting along the elongated hole 1c, bring it into contact with the other side of the angle A, and place the bolt 6
Attach it to the front plate. This prevents the main body from rotating relative to the footrest bar. Finally, clamp pieces 7, 7
Sandwich the rail R with the rails and tighten bolt 4 to secure it to the apron plate.

とが特徴である。 The above explanation was based on the vertical main material being an angle.
It is clear that it can be implemented as a channel or a pipe, regardless of its size. Since conventional devices were attached to vertical main members, they lacked the above-mentioned versatility and had the inconvenience of having to be designed and manufactured on a case-by-case basis. The present invention is characterized by improving this point by using a foothold bar as the object of attachment.
