Abstract

<P>PROBLEM TO BE SOLVED: To provide a stepladder with a sliding mechanism and a stopper mechanism for stabilizing the stepladder at a construction site excepting a horizontal place or on staircases or the like. <P>SOLUTION: A sliding groove is formed to a stepladder body 2, and a sliding section 1 can be expanded and contracted. A structure fixing the sliding section is mounted on the stepladder. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

発明の詳細な説明Detailed Description of the Invention

この発明は、水平な場所以外での工事現場又は階段などで安全に高所作業をするための脚立に関するものである。  The present invention relates to a stepladder for safely working at a high place on a construction site or stairs other than a horizontal place.

従来は、水平な場所でのみの使用か、別の人に支えて貰って不安定な状態で使っていた。  Conventionally, it was used only in a horizontal place, or it was used in an unstable state by being supported by another person.

発明が解決しようとする課題Problems to be solved by the invention

これには、次のような欠点があった。
(イ) 脚立脚部の長さが決まっているため設置する場所の水平と一定の広さが必要であった。
(ロ) (イ)の条件以外での使用については、別の人の補助が必要であったり不安定な状態で、使用者が非常に危険で、事故の原因となっていた。
(ハ) 何種類かの長さの異なる脚立を持つ必要があり、収納場所に困ることがあった。
本発明は、これらの欠点を除くためになされたものである。
This has the following drawbacks.
(B) Since the length of the stepladder leg is fixed, the installation place must be horizontal and have a certain size.
(B) Regarding use other than the conditions in (a), the assistance of another person was necessary or unstable, and the user was extremely dangerous and caused an accident.
(C) It was necessary to have several types of stepladders with different lengths, and there was a problem with the storage location.
The present invention has been made to eliminate these drawbacks.

課題を解決するための手段Means for solving the problem

脚立脚部4箇所にスライド機構をつけ、手動ストッパー機構図3を設ける。
本発明は、以上のような構成からなる、コンパクトスライドストッパー付脚立である。
A slide mechanism is attached to the four stepladder leg portions, and a manual stopper mechanism is provided in FIG.
This invention is a stepladder with a compact slide stopper which consists of the above structures.

本発明の実施の形態Embodiment of the present invention

以下、本発明の実施の形態について説明する。
(イ) 本体(2)の両端に、スライド溝を設け、スライド部(1)を装着する。
(ロ) 本体(2)に、ストッパーつめ(3)、スライド部(1)に(3)が噛み合うストッパー(4)を設け、バネ(5)によって保持する機構とする。
(ハ) バネ(5)は、脚立ステップ(7)を下げることによって固定され、上げることによって解除できる構造とする。
(ニ) ステップ(7)は、ステップスライドピン(8)ステップスライドピン受(9)ステップ固定スプリング(10)によって、容易に外れない構造とする。
本発明は、以上のような機構を持ち、これを使用するときは、スライド部(1)を縮めた状態から指示ラインまで本体(2)を開き、ステップ(7)を下げ、バネ(5)を固定し、ストッパーつめ(3)を保持する。設置する場所にあわせて、4箇所のスライド部(1)を伸ばし、スライドストップ(6)までの範囲内で、本体(2)が安定するよう固定する。
また、逆に収納するときは、ステップ部(7)を押し上げ、ストッパーつめ(3)をフリーにして、スライド部(1)を本体(2)に収納し、ステップ部(7)を下げ固定する。
Hereinafter, embodiments of the present invention will be described.
(A) A slide groove is provided at both ends of the main body (2), and the slide part (1) is mounted.
(B) The main body (2) is provided with a stopper claw (3), and the slide part (1) is provided with a stopper (4) that engages with (3), and is held by a spring (5).
(C) The spring (5) is fixed by lowering the stepladder step (7) and can be released by raising.
(D) The step (7) has a structure that is not easily detached by the step slide pin (8), the step slide pin holder (9), and the step fixing spring (10).
The present invention has the mechanism as described above. When this mechanism is used, the body (2) is opened from the contracted state of the slide portion (1) to the instruction line, the step (7) is lowered, and the spring (5) And hold the stopper pawl (3). According to the installation location, the four slide portions (1) are extended and fixed so that the main body (2) is stable within the range up to the slide stop (6).
When storing in the reverse direction, the step portion (7) is pushed up, the stopper pawl (3) is released, the slide portion (1) is stored in the main body (2), and the step portion (7) is lowered and fixed. .

発明の効果The invention's effect

このように、段差のある場所でも、脚立を安定して使用できるので、高所作業を安全に行うことができる。  Thus, since the stepladder can be used stably even in a place with a step, it is possible to safely perform work at a high place.
