Abstract

The desk has a part of the top plate (1) cut into a separate piece (2) for pivotally moving its forward side on pivot pins on the rear side. Guide members (7) are fixed to the back of the moving plate forward part and have respective guide slits (14) formed along the central lines to receive respective guide bolts fixed on the desk side walls, the pivoting being actuated by a handles fixed to the end of the guide member (7). The pivoted desk part stops by the adjustment of a fixing nut (9) on the top of the bolts (6).

The present invention forms a recess in the front surface of the desk plate, and the operating plate and the locking plate are constructed as hinges so that the lifting plate is adjusted as the height of the lifting plate is adjusted by the guide member fixing. Therefore, it relates to a desk that can be used as a drawing board or other reading table as well as an office desk by adjusting the angle at the desk board.

Currently, the desk plate is usually flat and fixed to the body of the desk. When sitting on a chair, the back and upper body should be bent forward as shown in Figure 4a. Long-term use not only causes fatigue on the lower back, but also causes a lot of fatigue on the eyes and neck as the upper body is bent on the desk board. .

There are also drawing boards where the whole board is lifted, but this is only used for a specific purpose, and because the whole desk is elevated at an arbitrary angle, there was a drawback that you could not place other things on the desk, such as other books or other objects that you are not currently looking at. .

The present invention eliminates the conventional drawbacks by using only the necessary parts such as the operation plate or the hanger plate, as well as the general desk as needed, as described above in detail by the accompanying drawings Is as follows.

A recess 13 is formed in the front surface of the desk plate 1 so that the operating plate 2 and the locking plate 3 are constructed as hinges 4, and the lower end of the operating plate 2 is provided with a handle 8 at the center. The bracket 11 provided with the guide member 7 having the long hole 14 formed thereon to be elevated in the high information bolt 6 protruding from both sides 5 of the desk, and the protrusion 10 at the bottom of the stopping plate 3 mounted on the desk body. The reference numeral 9 in the drawing as being rotatably arranged at the tip of the control opening 12 is a fixing nut for fixing the guide member (7).

In the present invention thus formed, when the operation plate 2 is raised at an arbitrary angle, the fixing nut 9 is first released from the high information bolt 6 protruding from both sides of the desk, and the handle 8 is held by the guide member ( 7) When the guide member 7 and the operating plate 2 are raised upward, the operating plate 2 is also raised as the guide member 7 is raised, so that when the user reaches the required angle, the fixing nut ( When the 9) is firmly assembled to the high information bolt 6, the guide member 7 is coupled and fixed while the operation plate 2 is installed and fixed by the hinge 4 at a predetermined inclination angle in the desk plate 1 recess 13. When a book or other object placed on the inclined operating plate 2 flows down, turning up the adjusting tool 12 provided in the bracket 11 will be centered on the hinge 4 as illustrated in FIG. As a result, the locking plate 3 is raised at an arbitrary angle, so that of course, reading and drawing boards As usefully used in the present invention, since the inclination angle of the operation plate 2 and the stopping plate 3 can be easily adjusted arbitrarily according to the user, it can be used by anyone, men and women, and the operating plate 2 and the stopping plate 3. Except for the rest of the desk (1) is always fixed to the desk in a horizontal state, it is more convenient to use because you can place other books or other mugs or other objects here.
