Description

[Detailed description of the invention] <Industrial application field> This invention is a standing work used to sit down when performing cutting work or assembly work in a standing posture on a work table of a waist high level. Seating device.

<Background of the conventional technology and its problems> Generally, when many cutting parts and assembly parts are placed on a work table of a waist height, the worker stands up from the viewpoint of workability. However, it is very difficult for the worker to stand in a standing position with only his hands moved for a long time (2-4 hours) at a fixed position, let alone in the cold season of winter. However, the operator is more tired by the posture than the tiredness of work such as cutting with a cutting tool and assembling with an assembling tool, and a countermeasure against it is desired.

As a solution to such inconvenience, it is conceivable to use a well-known office chair or the like, but the well-known chair structure cannot be expected to have stability unless you sit down with your back deeply seated. Since it is manufactured, there is a risk that it may roll over, and its use is impossible.

<Problems to be Solved by the Invention> The present invention has been made in view of the above-mentioned conventional circumstances, and a technical problem to be solved is to provide a footrest portion for an operator to maintain stability by his / her weight. (EN) Provided is a stool having a stool that can lean down in a state close to an upright posture to reduce the burden on an operator who performs operations such as cutting and assembling in the upright posture.

<Means for Solving the Problem> The technical means taken by the present invention to solve the above-mentioned problems is to allow the upper end to be opened or continuously provided at a waist height of an operator on a footrest plate formed to a desired size. The columns are vertically installed in a facing relationship, and the stool rod on which the worker leans his / her back is mounted so as to be vertically displaceable between the columns.

<Operation> Therefore, the above-mentioned technical means of the present invention displaces the stool rod mounted between the two columns to position and mount the stool rod at the waist high position of the worker (user). By resting on the footrest plate, you can take a comfortable standing posture with your back leaned against the stool.

<Embodiment> An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows the first embodiment, and the apparatus body (A) is a footrest plate (a ₁ ).
Two struts (a ₂ ) whose upper ends are open or are continuously arranged are installed in a standing manner in a facing relationship, and a stool rod (a ₃ ) on which a worker leans back is elevated between the struts (a ₂ ). It is constructed by disposing the body so that it can be displaced.

The footrest plate (a ₁ ) is formed of a rigid material such as metal into a flat rectangular shape or a round shape having a desired size, and the entire surface thereof is provided with a slip stopper (1). Be careful not to inadvertently slip your feet when leaning on the rod (a ₃ ).

The pillar (a ₂ ) is formed by cutting a square pipe made of metal or the like into a length that is higher than the waist height of the worker, and the legs of the square pillar (a ₂ ) with their flat sides facing each other. The mounting plate (a ₁ ) is integrally fixed and erected on the rear side of the opposite edges of both sides via the reinforcing plate (2).

Then, a plurality of height adjusting latching recesses (3) for the stool rod (s ₃ ) that are evenly spaced in the vertical direction are formed on the upper ends of the left and right columns (a ₂ ) by notching and opening. The upper end opening of the strut (a ₂ ) is closed by a stopper lid (4) made of a desired material such as rubber or synthetic resin so as to cover the opening edge surface, and the waist rod (a ₃ ) is seated. Safety is taken into consideration so as not to get injured when a part of the body such as an arm is accidentally touched during hanging work.

In addition, the standing interval between both columns (a ₂ ) is 1.5 from the waist width of the worker.
It is optional to set the distance to a certain extent or slightly narrower than the width of the work table (B), and a wide lateral device body in which both columns (a ₂ ) are erected at intervals slightly narrower than the width of the work table (B). By constructing (A), the operator does not have to laterally move the apparatus main body (A) during work such as cutting work on one side of the work table (B) and assembly work on the other side. Only by laterally moving, it is possible to take a posture of leaning on the waist, which increases the degree of freedom.

The height adjusting hook recesses (3), which are notched and opened in both columns (a ₂ ), are formed in the shape of a key in the front opening, and the stool rod (a ₃ ).
Both end portions of the hook can be freely inserted into and removed from the respective hook recesses (3) to be hooked.

The stool rod (a ₃ ) is cut into a length extending between both columns (a ₂ ) on which a circular pipe or rod having rigidity such as metal is erected, and urethane foam or urethane foam is formed on the outside except both ends thereof. A soft member (5) such as cloth is wound and attached with a desired thickness to give elasticity so as not to directly touch the rigid stool (a ₃ ).

Thus, the worker can adjust the seat rod (a
By adjusting and displacing the height of ₃ ), it is possible to perform work such as cutting and assembling in a comfortable posture with the back leaned (see FIG. 2).
