The desks and chairs supplied to the classrooms of the school or the classrooms of the school and used by students or students are standardized in a certain size. However, students or their students all have different body shapes and physique positions, and only a few can use desks or chairs of the appropriate height, while others have to take classes or take classes at desks of inappropriate height.

In particular, the height of the desk or chair used by elementary school students with rapid growth is showing a great difference between the lower grades and the higher grades. Therefore, it is necessary to arrange student desks in order of class height or desks of different heights in order according to the height of students.

In consideration of these problems, desks that can adjust heights have been developed and are being partially distributed to schools and academies.

Figure 1 shows the structure of a conventional height adjustable desk.

According to this, the desk frame is produced by separating the upper frame 20 and the lower frame 10, the upper frame 20 is fixed to the drawer 30 and the upper plate 40 fixed to the lower frame 10 When combined, using the height adjuster 11 provided in the lower frame 10 to adjust the overall height of the desk to the desired height.

It's past and fixed.

This conventional desk height adjustment device can adjust the height of the desk to the desired height relatively easily.

However, in the conventional desk height adjustment device as described above, when an external force is applied to the desk plate 40 or the entire frame, the clearance between the adjustment groove 21 and the tightening bolt 12 of the height adjuster 11 on the upper frame is opened. As the coupling state of the frame is loosened, noise is generated or the height adjuster 11 is easily damaged. This hurts the classroom and increases the cost of desk maintenance.

In addition, the conventional desk height adjusting device is mounted on the connection point between the upper frame and the lower frame, the height adjuster must have a certain degree of strength maintenance and screw grooves by itself, inevitably increases its volume, so the appearance of the desk looks clunky. Also has its drawbacks.

The purpose of the present invention is to simplify the height adjustment structure of the desk to simplify the height adjustment of the desk, and to keep the appearance of the desk beautifully, and to adjust the control part without damage even if repeated external force is applied to the desk. To provide a desk height adjustment device that can be easily supported.
