Description

[0001] The present invention relates to a desk having a height and an angle adjustment structure,

The present invention relates to a desk, and more particularly, to a desk which can adjust a height of a top plate according to a user's body condition and can adjust the angle of a top plate according to a user's use condition To improve efficiency of desk use.

In general, a desk is a tool used to read or write a book. It helps to improve concentration by lessening fatigue by inducing a stable posture in the process of reading or writing a book.

On the other hand, such a conventional desk is provided with an upper plate, and both sides of the upper plate are provided with a support for holding and fixing the upper plate at a predetermined height.

That is, the user is provided with a chair corresponding to the height of the top plate, and reads or writes the book on the top board in a sitting position.

On the other hand, in using such a desk, it is possible to improve the concentration and fatigue by using the user as comfortable and stable as possible.

However, such a conventional desk always has a fixed external shape, and a child or a teenager rapidly grows their physical condition. For example, a desk used when a child is grown does not match the height of a child when growing. There is a problem in that it becomes impossible to use it and an economical burden of having a new desk is added.

In addition, these desks are always in a parallel fixed state, so that when the user reads a book or writes, the user always takes a position to bend the neck downward. In this process, There was a problem that the neck part was easily packed and fatigued easily.

In order to solve the above problems, a desk having height adjustable as disclosed in the Utility Model Application Publication No. 1995-0022589 and a desk capable of adjusting the angle of the top plate such as the Utility Model Application No. 20-0353767 It has been proposed.

However, the above-mentioned conventional desk has a completely manual adjustment structure for adjusting the height thereof, and there is a great inconvenience in using the giant bar which has to adjust the height of each desk while alternately adjusting the height.

In addition, since the manual adjustment structure is also provided for adjusting the angle, it is not efficient for the child to use the heavy roof because of the inconvenience of the use of the heavy roof.
