なる構成を有する。Accordingly, in this invention, as shown in the illustrated embodiment, a recess 2 that opens on either the upper or lower side is provided in one 1a of the left and right horizontal parts 1a and lb of the chair frame.
A connecting pin 4 having a protruding edge 7 at the base end and a hook portion 3 at the tip is inserted so as to be rotatable and retractable.
The connecting pin 4 is always biased in the insertion direction by a coil spring 5 interposed in a compressed state between the proximal spring holder 7 and the spring holder 8 provided in the recess 2 in a compressed state. A locking hole 6 into which the hook portion 3 of the connecting pin 4 fits is bored at a position corresponding to the recess 2 in the other horizontal portion 1b.

である。The frame of the chair is made of a metal pipe with a rectangular cross section, and the recess 2 and the locking hole 6 are provided in horizontal parts 1a and 1b for elbow rests, which are bent in the middle of the front leg frame of the chair. However, the formation parts of the recesses and locking holes are not necessarily limited to the horizontal part for the armrest, and although not shown, in a chair that has a support frame on both sides of the seat, the formation part is not necessarily limited to the horizontal part for the armrest. It is also possible to provide it in a horizontal part.
また前記凹所２および係止孔６は意匠上の要求がら水平
部１ａ、ｌｂの下面に開口して設けられているが、上面

。Further, the recess 2 and the locking hole 6 are provided to open on the lower surface of the horizontal portions 1a, 1b due to design requirements, but may be provided on the upper surface to give priority to ease of connection and separation operations.
凹所２は連結ピン４の径より径大で、かつ水平部１ａの
上下面間の長さと略同寸のパイプを、水平部１ａの下面

て形成されている。The recess 2 has a diameter larger than that of the connecting pin 4, and a pipe having approximately the same size as the length between the upper and lower surfaces of the horizontal portion 1a is inserted and fixed into the horizontal portion 1a through a hole drilled in the lower surface of the horizontal portion 1a. It is formed by

より径大の内径を有する環状の金属板よりなっている。Further, the coil spring 5 is externally fitted into the connecting pin 4,
The spring retainer of the recess 2 has a flange 8 which is welded to the opening edge of the recess 2 and has an annular shape having an inner diameter smaller than the diameter of the opening of the recess 2 and larger than the diameter of the connecting pin 4. It is made of metal plate.

論、はとんど目につかないようになっている。Further, a hole 9 is bored in the lower surface of the horizontal part 1a of the frame at a predetermined distance from the recess 2, and when the chair is separated, the hook part of the connecting pin 4 is formed as shown in FIG. The vertical part of the hook part 3 is inserted into the hole 9, and only the horizontal part of the hook part 3 is exposed along the lower surface of the horizontal part 1a of the frame, so that the connecting pin 4 does not get in the way. Of course, it is almost invisible.

の相対的遊動をも阻止されるので、使用者が起座するも
椅子の横列隊形が乱れるおそれがない。Since this idea has the above-mentioned usurpation,
Pull out the connecting pin 4 from the recess 2 against the elastic force of the coil spring 5, rotate it so that the hook part 3 protrudes to the side of the frame, and insert the tip end into the horizontal part 1b of the frame of the adjacent chair. By inserting the hook portion 3 into the locking hole 6 provided in the locking hole 6, the hook portion 3 is locked in the locking hole 6 by the spring force of the coil spring 5.
Of course, they can be connected to each other, but in this connected state, the horizontal parts 1a and 1b are prevented from relative movement in any of the front, back, left, and right directions, so even if the user gets up, the horizontal parts of the chair There is no risk of disrupting the formation.

の操作が椅子を動かしたりすることなく手先で極めて簡
単に行ない得る。The connecting pin 4 in the connected state can be disconnected by pulling it downward against the spring force of the coil spring 5 and letting the barb hook part 3 escape from the locking hole 6. can be done very easily with one's hands without moving the chair.

が損われる虞れもない。In addition, unlike those in which the connecting fittings are attached to the sides of the chairs protruding, the chairs can be closely connected, and the connecting pins 4 are pulled out of the recesses 2 only when connecting or separating. is held in the recess 2 so that only the hook portion 3 is exposed.The tip of the hook portion 3 is inserted into the locking hole 6 when connected, and the connecting pin 4 is held even when separated. The connecting pin 4 can be rotated and fixed in position along the longitudinal direction of the frame horizontal part 1a by the coil spring 5, so that the connecting pin 4 does not get in the way in either connection or separation state. Of course, if it is provided on the underside of the frame, it will hardly be visible and there is no risk of spoiling the appearance.
