Abstract
Description
More particularly, the present invention relates to a table having an X-shaped guide rail to firmly support a table top plate, a support leg to which one end is moved along a guide rail, The present invention relates to a table capable of freely adjusting the height and inclination of a table top plate by a simple and reliable mechanism through a position fixing means for restricting movement of a folding guide link and a support leg to guide the folding of the support legs.
Generally, operations such as production, assembly, sorting, and packaging of articles are carried out on a work table.
The work table is generally referred to as being fixedly mounted so as to be capable of placing a product or processing various production processes, and has processed a repetitive production process by fixing the work table at a predetermined position.
Such a conventional work table can be conveniently used for fixed work without change. However, if the conditions such as the shape and size of the product, the height of the worker, and the like are changed, the work table may be rather inconvenient.
As an example of this, if the difference between the height of the worker's key and the height of the work table is large, the worker must work for a long time in a bent posture such as the back and the back, and as a result, fatigue is felt quickly, resulting in deterioration of concentration, It is accompanied by occupational diseases such as muscular pain and waist disk of the worker severely.
In addition, the work such as welding and assembly is not performed in one direction, but it is necessary to change the position according to the shape and characteristics of the object, but the fixed work table can not adjust the angle, and the worker has to move and work.
As a prior art technique to overcome such problems, a "work table" has been proposed in Japanese Patent Registration No. 10-0194883 (issued June 15, 1999) in which the angle of a work table can be adjusted as desired by an operator .
