Description

Flat bench using as working table by convenient height-adjustable}

The present invention relates to a workbench that is easy to adjust the height, and more specifically, it can be used as a bench where workers can take a break in a workplace by lowering the height of the top plate, and it can be used as a workbench by simply adjusting the height of the top plate. It relates to a bench for easy height adjustment that is configured to be used for both benches.

In general, when a large number of workers work in a workshop where several people work together or in an assembly site that produces a product, a bench or a bench is provided as a resting area for the workers to rest.

Since benches are not in a condition where multiple people can sit and rest at once, multiple benches must be installed to allow a large number of people to take a break, so the efficiency of use thereof is somewhat inferior.

On the other hand, the flat top is installed with a flat top plate at a certain height, and compared to its size, it is easy for many people to sit and take a break, so it is not only more efficient in use than the bench, but also provides a much more economical advantage compared to the installation cost of the bench. .

On the other hand, a workbench where workers work in a joint workshop or assembly site is provided at a certain height to facilitate the work of the worker.

However, since the height of the worktables installed in most work sites is a fixed type, it is difficult to arbitrarily adjust the height of the worktables, so it has a disadvantage that discomfort may occur depending on the size of the worker's body.

In addition, in the case of repairing facilities at a position higher than a person's height at work sites, it is generally common to use a ladder, but when using a ladder, the movement of the worker who climbed the ladder is very limited, so that the body cannot be balanced or the body is unreasonable. Accidents of falling on a ladder during movement often occur.

In order to overcome the disadvantages of using such a ladder, it is possible to install a scaffold to work, but it is difficult in reality to work with a scaffold because there are few cases where a scaffold is provided in a general work site.

On the other hand, it is possible to use a separate aerial platform or aerial vehicle for high place work, but such an elevated platform or aerial vehicle can be held by a company that specializes in aerial work. It is also very difficult in reality to have an aerial work table or an aerial work vehicle for work.

In other words, conventionally, a workbench installed at a site where a number of co-workers such as a factory or a large number of collaborators assemble products, or a ladder or scaffolding for high place work, and a high place workbench, which are convenient facilities provided for workers' rest, are separately configured. Since it is configured so that it can be used only for the purpose of each product, there are many practical difficulties because it is necessary to purchase all of the products or use them through rental, etc., when necessary for various tasks.

In addition, in order to install a conventional flatbed, workbench, or elevated workbench, it must be installed in a place where a flat floor is maintained so that the top plate or the top of the workbench can be kept in a horizontal state, so the installation place is very limited, and the floor surface is not flat. In places where it is not possible, a separate anchor tree or support should be supported on the leg to maintain the horizontal state of the top plate.If the anchor tree or support cannot be firmly installed, there is a risk that it may be difficult to use or a safety accident may occur during use. Existed.

This design was devised to reduce the inconvenience of having to equip both a bench, workbench, and high place workbench with high usability in the conventional worksite, and it can be used as a normal bench for work breaks in normal times, and assembly or packaging of parts as necessary. It is also possible to use a workbench used for the back, and the purpose of this is to provide an easy-to-adjust workbench that can be used as an aerial workbench when working at a height higher than a person's height.

In addition, the present invention is not limited to the place because it is convenient to maintain a horizontal state by simply adjusting the inclination of the upper plate even in the place where the floor on which the workbench is installed is not flat, so it is convenient to use and prevents safety accidents. There is another purpose to provide a common workbench that can be easily adjusted in height.
