Description

High and low dgtail regulation for desk and chair}

The present invention relates to a height adjusting device for a book and a stool, and more specifically, a height adjusting device for adjusting the height of a leg on a book and a stool is installed and configured, and according to the physical condition of the user using the book and the stool. Arbitrary height adjustment is basic and it is possible to fine tune the height here.

Generally, desks and stools are used in schools, such as the existing desks and stools have not only a uniform height is made of uniform height, there was no separate function to adjust the height.

As a result, students whose physical condition is very different from each other may use desks and stools that do not match their physical condition, causing the eyes to bend easily due to the bending of the waist or the out-of-focus distance of books and eyes placed on the desk. The mental and physical stress of the building caused a huge obstacle to the development of a healthy mind and body, and accordingly, there were many problems such as being unable to work efficiently.

Therefore, in recent years, many books and stools that have been installed with height adjusting devices to adjust the height of the legs have been conceived, but almost all of them are very inconvenient to adjust the height of the legs, and there are many problems in the rigidity of the height adjusting devices. If you receive a lot of problems, there was a problem in reliability, such as not being able to use it with confidence due to a short break, and most importantly, the most important disadvantage is that a fixed height adjustment width is formed at every step during height adjustment, so that fine adjustment is impossible. In particular, the height of books and stools can not be arbitrarily adjusted to best suit the physical condition of students who are using desks and stools for a long time, so they cannot completely reduce the fatigue of eyes as well as spine deformation of the user's back or waist. There was a big problem.

The present invention has been devised in view of the above-mentioned problems in the related art, and the special configuration of the height adjusting device of the book and the stool makes the height adjustment of the book and the stool very convenient, accurate and solid, of course, The most important thing is that even fine adjustment is possible, so that the height of the book and the stool can be arbitrarily adjusted according to the physical condition of the user, especially the students who are using the desk and the stool for a long time. It aims to completely reduce spine deformation of the user's back and waist as well as to reduce eye strain and to help the development of a healthy mind and body.
