支持板２４とともに、枢軸２３回りに回動して、
受圧溝２１の最凹部に嵌入して、押圧カム２０と
押圧杆１９を、圧縮ばね２２に抗して押し下げよ
うとする。 In the chair A 1 in the above-mentioned state, when the seat plate 26 is flipped up backwards and overlapped with the back plate 16, the pressing pin 25 is moved as shown in the chair A 2 shown in FIG.
Rotates around the pivot 23 together with the support plate 24,
It fits into the recessedmost part of the pressure receiving groove 21 and tries to push down the pressing cam 20 and the pressing rod 19 against the compression spring 22.
しかし、押圧杆１９の下端は支軸６に当接して
いるので、圧縮ばね２２の力によつて、押圧カム
２０は押し上げられ、これとともに脚柱１４は上
昇し、その切欠部１７は係合ピン８より離脱す
る。 However, since the lower end of the pressing rod 19 is in contact with the support shaft 6, the pressing cam 20 is pushed up by the force of the compression spring 22, and together with this, the pillar 14 rises, and its notch 17 is engaged. It separates from pin 8.
従つて、第５図に示す椅子A3のように、椅子
全体を、脚柱１４の前縁下部が、前方停止杆５に
当接するまで、支軸６まわりに水平に前倒するこ
とができる。 Therefore, as in chair A3 shown in FIG. 5, the entire chair can be horizontally tilted forward around the support shaft 6 until the lower front edge of the pillar 14 comes into contact with the front stop lever 5. .
この時、第５図に示すように、回動する係合部
１７により、解除レバー９の前端が押し上げら

ａを押して、支持板４の凹入溝１２より押し出す
ので、椅子A3を、後方の収納部２に押し入れる
ことができる。 At this time, as shown in FIG.
Since the chair A 3 is pushed out of the recessed groove 12 of the support plate 4 by pressing a, the chair A 3 can be pushed into the storage section 2 at the rear.
収納された椅子A3を引き出して、椅子A2のよ
うに垂直とすれば、弾性ストツパ１３の山形部１
３ａが、弾性により支持板４の凹入溝１２に嵌入
して、椅子A2が後退不能にロツクされる。 If the stored chair A 3 is pulled out and made vertical like chair A 2 , the chevron portion 1 of the elastic stopper 13
3a is elastically fitted into the recessed groove 12 of the support plate 4, and the chair A2 is locked so that it cannot be moved back.
座板２６を水平に倒せば、椅子A1のように、
脚柱１４が下降して、係合部１７が係合ピン８に
係合することにより、脚柱１４は前傾不能にロツ
クされて、着席可能の状態となる。 If the seat board 26 is laid down horizontally, it will look like chair A1 .
When the leg column 14 is lowered and the engaging portion 17 engages with the engagement pin 8, the leg column 14 is locked so that it cannot tilt forward, and becomes ready for seating.
