[Prior art and its problems]

  Satisfies the needs of the consumer market as the industry has often developed chair structures We are striving to be able to do it, and the type and place where general consumers prefer and personal use You can freely select and use it. Here, a kind of consumer buys himself They will explain the chair structure that can be assembled by themselves. This self-assembled chair (10) is a sitting unit (20) and a back support unit (30) as shown in FIG. ) And the left and right side support units (40) and (50). The holes (401), (402) near the lower end of the side support unit (40) The seating unit (20) is preliminarily applied to the front and rear support parts (201) and (203) of the bottom part. It is aligned with the holes (202) and (204) to be machined, and screwing means (60 ), The two members are screwed together to be integrated, and the back support unit (30) and hold the pre-formed hole (301) on one side thereof. Position and screw into the hole (403) near the upper end of the support unit (40) It is screwed together by means (60) and then on the other side of the support unit (50 ) Near the lower end of the seat (501), (502) the front and rear support of the sitting unit (20) Preliminarily machined holes (202), (2) in the holding parts (201), (203) 04) and integrate the two members by screwing means (60). So that the support unit (50) is screwed by screwing means (60). Other preformed parts of the hole (503) near the upper end and the back support unit (30) The chair (10) is processed and formed by aligning with the hole to be screwed and then screwed. The chair Since the head of the screwing means for connecting the entire structure is directly exposed to the outside, The overall aesthetics may be deteriorated, and the constituent members are pre-formed with screw holes. Therefore, there is an error in the precision of the height of the hole and the precision of alignment, and therefore, It is quite difficult for the user to assemble the chair structure himself to balance both sides. And, after the chair has been used for a certain period of time, the screwing structure of the connecting part is The member is loosened between the screwing means due to downward pressure and movement during cleaning. The user should not be very careful, as this often results in Otherwise, if you easily sit on the chair, it will result in the chair collapsing.
