Description

[Detailed explanation of the idea] Purpose of invention (Industrial application field) The present invention relates to a support for supporting a ladder.

(Prior Art) A typical ladder is made up of a pair of vertical members and a plurality of horizontal members stretched between the vertical members, and is used, for example, to lean against a house and climb up and down the ladder. However, since the ladder was simply left upright, it was unstable and there was a risk of the ladder falling off.

Therefore, various efforts have been made in the past. For example, as seen in Utility Model Application Publication No. 59-90000,
A hook is provided at the upper end of the ladder, and this hook is hung on a predetermined part of the house, such as the edge of the roof, to prevent it from coming off.

Another method is to attach a support to the roof board and connect the support to the upper end of the ladder using a connecting strip such as a string. To be more specific, the roofs of houses, especially the roofs of prefabricated houses, are sometimes made of metal plates, so-called folded plates, which are formed with alternating peaks and valleys extending parallel to each other. This roof plate is attached to a roof frame or the like with bolts and nuts. In other words, the bolt is fixed to the roof frame, etc., and its tip protrudes upward and passes through a hole formed in the peak of the roof shingle.By tightening the nut screwed into the tip of the bolt, The roof shingles have been installed. The support has holes for bolt insertion, and is attached to the roof board using the bolts and nuts.

(Problems to be Solved by the Invention) In the former conventional example, a hook was attached to the ladder, making it inconvenient to handle during transportation.

In the latter conventional example, holes for bolt insertion had to be formed in the roof plate, which caused leakage and corrosion.

Structure of the invention (Means for solving the problems) The invention was made to solve the above problems, and its gist is that peaks and valleys extending parallel to each other are formed alternately, and A ladder support that is attached to a roof plate having curved overhangs on both sides of the crest, which has a hook part for hooking a connecting strip connected to the upper end of the ladder, and has a hook part that hooks a connecting strip connected to the upper end of the ladder, and has at least two ridges of the roof plate. a main body that spans over the roof plate; and at least one main body that is provided at a position corresponding to the at least two peaks of the roof plate of the main body, has a curved shape along the outer surface of the projecting part of the roof plate, and is fitted into the projecting part. The present invention provides a ladder support comprising a pair of engaging portions.

(Function) The support of the present invention is fixed to the roof panel by spanning the main body over at least two peaks of the roof panel and fitting the engaging portion into the projecting portion of the roof panel. The ladder is supported by connecting the main body of the support and the upper end of the ladder with a connecting strip.

(Example) Hereinafter, an example of the present invention will be described with reference to the drawings. The ladder 10 includes a pair of vertical members 11 and
It consists of a large number of cross members 12 suspended between them. When this ladder 10 is placed against a house 20, for example, as shown in FIG. 2, it is supported using the support 30 of the present invention.

Roof parts 20a, 20 of the first floor and second floor of the house 20
b is a roof plate 2 made of a so-called boltless folded plate.
1. The roof plate 21 has alternating peaks 22 and valleys 23 that extend parallel to each other.
Overhanging portions 24 are formed on both sides of the mountain portion 22,
An inclined portion 25 is formed between the overhang portion 24 and the trough portion 23 and is inclined so as to widen downward. The overhanging portion 24 overhangs from the upper end of the inclined portion 25 in the lateral direction. The overhanging portion 24 is
It has a curved shape.

A fixing member 27 is provided on the roof frame 26, and a head 28 of this fixing member 27 projects laterally. By press-fitting the projecting portion 24 into the head portion 28 of the fixing member 27, the roof plate 21 is fixed without using bolts.

The support 30 according to the present invention has a main body 31 in the form of an elongated plate. The main body 31 is part 2 of the roof plate 21.
It has a length extending over two peaks 22.

Plate members 32 are fixed to the lower surface of both sides of the main body 31. The plate material 32 has engaging portions 33 at both ends. The engaging portion 33 has a shape that follows the outer surface of the overhanging portion 24 of the roof plate 21 and is curved. The engaging part 33 located on the outside has a screw hole 34.
is formed.

A nut 35 is fixed to the lower surface of the central part of the main body 31, and an eye bolt 36 is attached to this nut 35.
is screwed in. The eyebolt 36 has a ring-shaped hook portion 37 at its upper end.

The support 30 having the above configuration is attached to the roof board 21. That is, the main body 31 of the support 30 is
When the roof plate 21 is stretched over the two peaks 22 and pressed downward, the engaging portion 33 is elastically deformed and fitted into the overhang portion 24 .

After that, the fixing screw 38 is screwed into the screw hole 34 formed in the outer engaging part 33, and the overhanging part 24
By pressing the support member 30 against the outer surface of the support member 30, the support member 30 can be more securely fixed.

After that, one end of the connecting strip 39, such as a string, rope, or steel wire, is wrapped and fixed around the horizontal member 12 at the top of the ladder 10, which is leaning against the house 20, as shown in FIG. 2, and the other end is fixed. Wrap it around the hook part 37 of the eye bolt 36 and fix it.

As above, the upper end of the ladder 10 is connected to the roof plate 2
1, the danger of the ladder 10 coming off can be eliminated.

The present invention is not limited to the above embodiments and can be modified in various ways. For example, as shown in FIG. 4, the engaging portion 43 may be formed by bending both ends of the main body 41 of the support 40. Note that other members corresponding to the above embodiments are given the same numbers and their explanations are omitted. In this embodiment, the engaging portions 43 are a pair, and the two peak portions 2 of the roof board 21
It is fitted only into the outer protruding part 24 of 2.

Further, in the above embodiment, the hook portion for hooking the connecting strip was constructed with an eye bolt, but the hook portion may simply be formed by forming a hole in the main body, or the hook portion may not be provided in the main body. Alternatively, the connecting strip may be directly wrapped and fixed around the main body.

Alternatively, a special connector may be attached to the end of the connecting strip, and this connector may be connected to the main body side of the ladder or support.

Effects of the Invention As explained above, the support of the present invention can be attached to a roof plate made of so-called boltless folded plates, and can take advantage of the advantages of boltless folded plates. That is, since holes for bolt insertion are not formed in the roof plate, rain leakage and corrosion can be prevented. Furthermore, since there is no need to provide a hook or the like on the ladder, handling of the ladder becomes easier. Furthermore, since the support is attached by fitting the engaging portion of the support into the overhanging portion of the roof board, the support is securely supported and the installation work is easy.
