The present invention relates to a multi-purpose chair that can be used as a desk combined by fastening the back plate has a light cushion sense by the elasticity of the spring and can adjust the inclination and fasten the small reading stand with screws as needed. As a conventional technique, there is a means for adjusting the angle of the back plate by the fixing rod and the fixed teeth according to the desired angle for the angle adjustment of the back plate and the seat plate, as in Utility Model Publication No. 700 (Notice No. 85-234). However, it is inconvenient to adjust by hand for each desired angle, and the economic loss due to wear of the fixed teeth due to frequent use was large. In addition, Utility Model Publication No. 683 (Notice No. 84-2204) is a means for fixing a table plate to a chair by inserting a connecting rod into a fixed tube and fixing it. By supporting the table top with a single connecting rod configured to control the lack of means to support it when excessive force is applied to the table top, and thus it breaks quickly in use and lacks stability in use.

The present invention was devised to improve this. As a means of supporting the reading plate, two fixing tubes and two connecting rods were used to support the reading plate and adjust the angle of the back plate. If the locking bolt is used and described in detail based on the accompanying drawings as follows.

In the case where the whole chair is composed of iron pipes, and the desk plate 8 is installed on the seat plate 13 and the armrest fixing tube 2 on the chair post 1, the lower shaft pipe 5 of the backrest base 3 is Mandrel is fixed to the axial pin 11 fixedly installed on both sides of the support rod (1), and the back support pole (3) is tensioned by connecting the support post (3) and the fixed pipe (2) with the tension spring (4). The front and rear flow of the shaft pin 11 is axially freed in the spring 4, but the locking bolt 6 is inserted into the shaft tube 5 with a screw so that the front end side thereof is provided on both sides of the chair span 1. If the supporting protrusions (7) attached to the ground is formed so that the backboard week (3) no longer falls backward.

On the other hand, the front of the fixed plate (2) is to be configured to be coupled to the friction bolt force by inserting the connecting rod (9) integrally with the reading plate (8).

1 is an overall perspective view of the present invention.

2 is a side view of the present invention.

Claims (1)

In the chair where the desk plate 8 is coupled to the fixed tube 2, the locking bolt 6 is caught by the support protrusion 7 at the rear side of the support rod 1, and the backing paper base 3 is attached to the axial pin 11 installed inwardly. 2) connecting rods supporting the reading plate 8 in front of both fixed pipes 2 by connecting the fixed pipe 2 and the backing paper 3 with a tension spring 4 by installing the shaft pipe 5 of the shaft as an axis. (9) Put a multipurpose chair that can be fixed by installing a butterfly bolt (10).
