To the upper end of the chair rear leg frame of the present invention for achieving the above object is coupled to the backrest tube formed on both sides of the backrest, and the hollow on the rear leg frame is coupled to the protrusion member formed on one side end of the arm restrained by fitting, but a plurality of protrusions on the outer peripheral surface Unevenness is formed, and the armrest cap integral with the protruding member is characterized in that it is coupled to the outer peripheral surface of the backrest pipe body.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a perspective view of one side of the armrest of the present invention in a separated state, Figure 2 is an enlarged perspective view of the armrest inserted into the rear leg frame of the present invention, Figure 3 is a cross-sectional view of the armrest of the present invention is combined. 4 is a perspective view of a desk according to another embodiment of the present invention.

As shown, the chair 1 comprises a backrest 2 and a seat plate 3 and front and rear leg frames 4 and 5 supporting them,

The outer back surface of the rear leg frame 5 is coupled to the backrest tube body 2 'formed at both ends of the backrest 2, and the protruding member formed at one end of the armrest 6 at the hollow 5' of the rear leg frame 5 6a) is coupled to the interference fit, a plurality of irregularities (6b) is formed on the outer peripheral surface of the projecting member (6a), the inner peripheral surface of the arm support cap (6c) integral with the projecting member (6a) is the backrest tube (2 '). It is configured to be coupled to the outer peripheral surface.

And the rear end of the frame 5, the upper end of the hollow (5 ') end of the desk frame (8) supporting the lower portion of the desk (7) is coupled by interference fit, the tubular member (9) coupled to the end of the desk frame (8) The inner circumferential surface is configured to be coupled to the outer circumferential surface of the backrest tube body 2 '.

The operation of the present invention configured as described above is as follows.

The chair (1) used for a movie theater or a music room is mainly assembled by the armrest (6). The protruding member 6a of the arm rest 6 is inserted into the hollow 5 'of the upper end of the rear leg frame 5, and the arm rest cap 6c is coupled to the backrest tube 2' of the backrest 2.

On the contrary, the chair 1 used in the academy or auditorium is a desk 7 mainly assembled, and the end of the desk frame 8 is fitted into the hollow 5 'of the upper end of the rear leg frame 5, and the tubular member 9 is provided. Can be used in combination with the backrest tube (2 ').

As above, it is possible to easily assemble and use the right one for the suitable place and to replace the one suitable for the place when moving to another place.

As described above, the present invention allows the arm rest or desk to be easily replaced at the upper end of the rear leg frame of the chair according to the user's purpose of use, so that the use range of the chair can be widely used, and also in one line in the manufacturing process. Various chairs are manufactured, but in the final process, by assembling the armrest or desk to suit the user's taste, it can be an efficient production method and can reduce the cost of the product due to a simple line.
