Abstract

(57) [Summary] [Purpose] To easily and safely connect the power tool to a power source when climbing on a stepladder and using the power tool, and to ensure safety during work. [Configuration] The feature is that an outlet for power tools is embedded in the top of the stepladder.

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention is suitable for improving stepladders used as scaffolding during interior finishing work of buildings. It is related to

0002

[Conventional technology]

When finishing the interior of a building, it is necessary to climb on a stepladder and use power tools. There are many cases where this is not the case. In such cases, use the plug that comes with the power tool. Conventionally, stepladder Electrician's drum on top (with an outlet for connecting power tools and connecting the outlet to the power source) Install a supplementary electric wire consisting of a long electric wire and a drum around which the wire is wound. I was using it by connecting a power tool to it.

0003 This requires the unstable movement of climbing onto a stepladder while holding a power tool and an electrician's drum. Not only is this required, but there is not enough space on the stepladder to allow electrician drums to fall. There was a risk of falling and there was a safety issue.

0004

[Problem that the idea aims to solve]

In view of the above-mentioned conventional drawbacks, the present invention provides a stepladder without the need to install the electrician's drum on the stepladder. To provide a highly safe stepladder on which electric tools can be used.

[0005]

[Means to solve the problem]

In order to solve the above problem, in this invention, an electric wire with a plug is installed at the bottom of the stepladder. An outlet connected to the electric wire is provided at the top of the stepladder.

[0006]

[Effect]

According to the above configuration, when using a power tool while standing on a stepladder, the plug at the bottom of the stepladder is Connect wires with tags to a temporary power source for construction work or an electrician's door that is connected to the power source and installed on the floor. You can connect it to the ram and use it by connecting power tools to the outlet on the top of the stepladder. Ru.

【Example】

FIG. 1 shows an example of a stepladder A according to the present invention. Stepladder A shown in the diagram is an interior finish of a building. It is used as a scaffold during construction work, and consists of four metal pipe supports 1 and It is equipped with a plurality of horizontal beams 2 installed between pillars 1.

[0008] At the bottom of the stepladder A, an electric wire 4 with a plug 3 is connected from near the lower end of one support 1 as shown in the figure. As shown in Fig. 1 by the imaginary line, the state in which it is used is pulled out from the pillar 1, and as shown in Fig. 1. As shown by the solid line, cut across the unused state stored along the relevant support 1. It is set up so that it can be changed freely. 5 is an opening formed on the inner surface of the support column 1, and 6 is an opening formed on the front side. This is an elastic locking claw that locks the electric wire 4 with the plug 3 in the unused state. It is attached to the pillar 1 on the side.

[0009] At the top of the stepladder A, there is a power supply connected to the electric wire 4 near the upper end of the support 1. The center 7 is buried with its outer surface flush with the outer surface of the support 1, and the The electric wire portion 8 between the outlet 7 and the above-mentioned drawable electric wire 4 is made of a metal pipe. The wires are inserted through the internal space of the support column 1.

[Effect of the idea]

Since the present invention has the above-mentioned configuration, when using a power tool while riding on a stepladder, , connect the electric wire with the plug at the bottom of the stepladder to a temporary power source for construction or the power source, and connect it to the floor surface. For use, connect the electric tool to the electrician drum installed in the can be used. Therefore, there is no need to lift and install the electrician's drum on a stepladder. There is no need to worry about falling off the stepladder, making it possible to work at heights safely.
