る。The interlocking mechanism 7 has a central portion pivotally supported by the upper rear end of the frame 3 via a horizontal shaft 5, and one end 9a of which is connected to the backrest 6.
an L-shaped arm 9 fixed to the lower end of the arm, a connecting rod 11 whose rear end is connected to the other end 9b of the iron arm via a connecting shaft 10, and a sliding shaft 12 fixed to the front end of the rod; a fixed guide plate 14 fixed to the frame 3 and having a long hole 13 for slidably guiding the sliding shaft in the front-rear direction; It consists of a connected seat plate mounting frame 15 and a seat plate advancement stopper 16 fixed to the front end of the mounting frame and slidably guided in the elongated hole 13.

なお、１７は前記椅子本体枠３の後面に固定された背板
で、その高さは机１８の天板１９の高さＥよりも小とさ
れている。Note that 17 is a back plate fixed to the rear surface of the chair body frame 3, and its height is smaller than the height E of the top plate 19 of the desk 18.

また前記椅子本体枠３の前後幅は前記背もたれ６の高さ
よりも大とされ、かつ机１８の天板１９の下部に形成さ
れた椅子収納スペースＦの前後幅Ｇよりも小とされてい
る。Further, the front-to-back width of the chair body frame 3 is larger than the height of the backrest 6, and smaller than the front-to-back width G of a chair storage space F formed at the lower part of the top plate 19 of the desk 18.

上記構成（ミおいて、使用状態の椅子を収納状態にする
には、背もたれ６を前方向へ倒す。In the above configuration, in order to put the chair in the used state into the stored state, the backrest 6 is tilted forward.

そうすると、第２図鎖線の如くＬ字形腕９は軸５周りに
回動し、その他端９ｂが下方へ移動する。Then, the L-shaped arm 9 rotates around the shaft 5 as shown by the chain line in FIG. 2, and the other end 9b moves downward.

そして、腕９の回動に従動して連結杆１１の後端も下方
へ回動しながら後方へ移動し、その前端の摺動軸１２は
案内板１４の長孔１３を後方向へ摺動する。Following the rotation of the arm 9, the rear end of the connecting rod 11 also rotates downward and moves rearward, and the sliding shaft 12 at the front end slides rearward through the elongated hole 13 of the guide plate 14. do.

そうすると、摺動軸１２に連結された座板取付枠１５も
後退し、座板４が後退する。Then, the seat plate mounting frame 15 connected to the sliding shaft 12 also retreats, and the seat plate 4 retreats.

そして背もたれ６が座板４とほぼ平行になるまで倒伏し
た折畳倒伏姿勢りで、座板４は本体枠３の前面よりも後
退した収納後退位置Ｂとなる。Then, in the folded and laid down posture in which the backrest 6 is laid down until it becomes almost parallel to the seat plate 4, the seat plate 4 is in the storage retreat position B in which it is set back from the front surface of the main body frame 3.

この状態では、背もたれ６の床面１からの高さは背板１
７の高さよりも小となり、本体枠３の前後幅も机１８の
スペースＦの前後幅Ｇより小となっているので、椅子は
天板１９より突出することなくスペースＦ内に収納で゛
きる。In this state, the height of the backrest 6 from the floor 1 is
7, and the front-to-back width of the main body frame 3 is also smaller than the front-to-back width G of the space F of the desk 18, so the chair can be stored in the space F without protruding beyond the top plate 19. .

また、収納状態の椅子を使用状態にするには、背もたれ
６を起立させる。Further, in order to put the chair in the stored state into a use state, the backrest 6 is raised.

そうすると、連動機構７が上記とは逆に作用し、座板前
進ストッパ１６が案内板１４の長孔１３の前側孔壁に当
接したときに、座板４の使用前進位置Ａと背もたれ６の
使用起立姿勢Ｃが得られる。Then, the interlocking mechanism 7 acts in the opposite manner to the above, and when the seat plate advance stopper 16 comes into contact with the front hole wall of the elongated hole 13 of the guide plate 14, the operating forward position A of the seat plate 4 and the position of the backrest 6 are adjusted. The used standing posture C is obtained.

収納スペース内に完全に収納することができ、更に本考
案によると、連動機構により、椅子の使用状態と収納状
態との切換を単純な操作で行い得る。As is clear from the above explanation, the present invention has a chair body frame with legs that stand up on the floor, and an upper part of the iron frame that can be slid horizontally back and forth between the forward position for use and the retracted position for storage. a seat plate placed on the frame, a backrest pivotably supported on the upper part of the frame so as to be able to switch between a standing position for use and a folded down position via a left and right horizontal axis; According to the present invention, the chair is provided with an interlocking mechanism for interlocking the backward sliding movement of the seat plate with movement and interlocking the forward sliding movement of the seat plate with the upright rotation of the backrest. In the stored state, the backrest is folded and laid down, and the seat board is in the retracted position, making it possible to make the chair more compact and store it completely in the storage space at the bottom of the desk top. According to the present invention, the interlocking mechanism allows the chair to be switched between the used state and the stored state with a simple operation.
