Description

Foldable working platform

The present invention relates to a workbench which a worker step on and off to work at a high point, and more particularly to a foldable workbench which can be folded down so that the total volume is reduced.

In general, the worktable is a mechanism that provides a stand space to enable work in a high place, and is widely used in a variety of places such as a home, an office, or an industrial field because it is stable, easy to use, and adjustable in height. For example, it can be used for various tasks such as assembling, disassembling, plastering, leaching, wallpapering, curtain installation, paint painting, store display, and car washing at a high position such as a wall or a ceiling Mechanism.

At this time, the workbench includes a main frame composed of a plurality of steel rods and standing on the ground, and a footplate made of a steel plate structure and horizontally mounted on the end of the main frame. At this time, since the worktable has a large total volume and is difficult to transport in the finished product state, the worktable is manufactured in such a manner that a plurality of members are combined in the field.

When the workbench is assembled at the construction site in such a way, there is a problem that a collapse accident may occur due to erroneous assembling or omitting the assembling member. In addition, since the height of the workbench and the size of the workbench are very large, there is a problem that there is a lot of difficulty in carrying the workbench to move the finished workbench. Of course, disassembling the workbench makes it easier to transport, but it takes a lot of time to disassemble and reassemble the workbench.

On the other hand, since the scaffolding foot of a worker is usually located at a height of 1 meter or more, there is a drawback that when the worker is raised on the scaffolding, the center of gravity of the worktable becomes higher and more likely to fall. Particularly, when the vertical bar of the main frame is erected perpendicular to the ground, even if a small external force is applied sideways, it can easily fall down.

Further, when the vertical bar of the main frame is erected perpendicular to the ground, the ladder mounted thereon is also erected perpendicular to the ground, and there is a fear that the operator may fall while climbing on the ladder.
