Description
【考案の詳細な説明】 (産業上の利用分野) 本考案は梯子に関する。DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a ladder.
(従来の技術) 住宅の建築、修理や屋根上に構造物を設置する作業等を
行うにあたって、軒先に梯子を立て掛けることが多い。
ところが、軒先には雨樋があるため単に梯子を立て掛け
ると梯子の自重および作業者の体重でこの雨樋が破損し
たり変形したりする虞れがある。(Prior Art) When building or repairing a house or installing a structure on the roof, a ladder is often leaned against the eaves.
However, since there is a rain gutter at the eaves end, if the ladder is simply leaned against, the rain gutter may be damaged or deformed due to the weight of the ladder and the weight of the operator.
そこで、本出願人は、実開昭59−60300号公報に
記載の上端部から延設した支持腕の先端部に一枚の幅広
の雨樋保護台を取付けた梯子を提供していた(以下、第
1従来例という。)。Therefore, the applicant of the present invention has provided a ladder in which a wide rain gutter protection table is attached to the tip of a support arm extending from the upper end described in Japanese Utility Model Laid-Open No. 59-60300 (hereinafter , Referred to as the first conventional example).

危険であり、使用できないという問題があった。基板が
一枚の幅広であると、屋根の突部に集中的に荷重がかか
り、この突部を破壊するおそれがあった。Further, two or more ladder split bodies described in Japanese Utility Model Laid-Open No. 58-130598 are elastically connected to each other, and one of the split bodies has an arm portion axially attached to the corner of the outer wall of the house and the eaves back portion. At the same time, it is a ladder provided with an auxiliary arm portion for fixing the arm portion in a thrusting posture, and a slip preventing portion made of a flexible material is formed at the tip of the arm portion, and the split body and the arm portion are formed. A ladder for narrow ground, in which an auxiliary arm portion is installed, has been proposed (hereinafter referred to as a third conventional example). (Problems to be solved by the invention) However, in the case of the first conventional example, when the ladder with a rain gutter protection stand is leaned against an uneven roof such as a corrugated roof or a corrugated roof, Since the substrate of the gutter protection table is a single flat plate having a wide width, the gutter protection table is not stably placed on the roof, which is very dangerous in performing the work, and there is a problem that it cannot be used. If the board is wide, a load is intensively applied to the protrusion of the roof, which may damage the protrusion.
また、第2従来例の場合、掛け金具を軒先部に挟み込ま
なくてはならず、この挟み込み作業が大変である上に、
屋根によっては軒先部が挟み込める構造になっていない
ものがあり、汎用性の面で問題があった。In addition, in the case of the second conventional example, the hanging metal fitting must be sandwiched between the eaves, and this sandwiching work is difficult.
Some roofs do not have a structure in which the eaves can be sandwiched, and there was a problem in terms of versatility.
さらに、第3従来例の場合、軒裏部に腕部が支持される
もので、屋根によっては軒先から軒裏部までの距離が長
いものもあり、これも汎用性の面で問題があった。Further, in the case of the third conventional example, the arm portion is supported by the eaves back part, and there is a case where the distance from the eaves to the eaves back part is long depending on the roof, which also has a problem in versatility. .

屋根の水の流れ方向に沿って細長く形成されている。The support base 5 is placed on the roof when the ladder main body 1 is leaned against the roof so that the upper portion of the ladder main body 1 does not come into contact with the rain gutter 10 provided at the eaves of the ladder main body 1. It supports the upper end portion, and is attached to the tip end portion of the support arm 4 rotatably in the roof flow direction as described above. A locking piece 8 projecting downward is provided at one end of the support base 5 on the side of the ladder body 1, and the locking piece 8 is locked to the eaves to stabilize the support base 5 on the roof. It is designed to be placed on the screen. On the lower surface of this support base 5,
A cushioning material (not shown) such as a sponge material or a rubber material is provided so as to prevent the roof material from being damaged by an impact when the support base 5 is placed on the roof. Support stand 5
Is attached to the tip of the support arm 4 so as to be rotatable in the flow direction of the roof, so that it can be stably placed on the roof according to the slope of the roof. Further, the support base 5 is formed to be elongated along the direction of water flow on the roof.

の上端部は雨樋と接触することなく軒先に支持される。As described above, both side frames 2a at the upper end of the ladder main body 1,
The two support bases 5 and 5 provided on the 2b via the support arm 4 are arranged at a predetermined distance from each other, and this space is such that when the support bases 5 and 5 are placed on an uneven roof such as a roof tile. It can be set at any time by taking into consideration the width of the ladder body 1 and the like so as to be placed at a stable position in the concave portion of the roof. Therefore, even if this ladder is leaned against an uneven roof such as a roof tile, both supports 5 and 5 are stably placed on the roof, and the upper end of the ladder is supported by the eaves without contacting the rain gutter. .

に行え、持ち運び等に便利である。Further, the arms 4 fixed to the side frames 2a and 2b, respectively.
The base ends of a and 4b are side frames 2a and 2b on which the cross rails 3 are located.
Are located on the outside of each of the bolts 6, 6
Is inserted through the inside of the cross rail 3 from the base end portions of the one arm body 4a, 4b, is inserted through the base end portion of the other arm body 4a, 4b, and is fastened by a nut (not shown). Bodies 4a, 4
The base end of b is fixed. Therefore, the support arm 4 can be firmly fixed to the ladder body 1, and the support arm 4 supporting the support base 5 and the ladder body 1 can be easily attached and detached, which is convenient for carrying.
さらに、支持腕4および支持台5の材質としては、アル
