実施例の図面により、本発明の構・成を説明する。The gist of the present invention is to provide a rotating seat on a fixed base that rotates about its vertical center line, and to pivot the lower part of the backrest to the rear upper part of the rotating seat by a back pivot point. The rear part is pivotally connected to the pivot seat in front of the back pivot point, and the front part is supported by the front support of the pivot seat, and the upper pivot is attached to the back rest above the back pivot point. The landing point and the lower pivot point provided on the seat at the lower rear of the seat pivot point are connected by a link, and a front stopper piece whose lower part is fixed to the front part of the fixed base is provided, and the lower part is attached to the rear of the fixed base. It has a rear stopper piece to which is fixed, and is located in the front-rear direction below the seat, the middle part is pivotally attached to the upper part of the rotating seat by a central attachment point, and the front end is engaged with the left side of the front stopper piece. A lever is provided, and an oblique part that slopes rearward and downward is provided on the upper surface of the rear part of the lever so that the rear lower part of the seat that is rotated downward presses the oblique part and releases the engagement with the front stopper piece at the front end. . DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be explained below with reference to drawings of embodiments of the present invention.

保つ。Although the structure for rotation is appropriate, in the figure, the lower part of the rotation seat 2 forms a cylinder 30 and is rotatably inserted into the fixed base 1. Place the lower part of the back support 3 at the rear upper part of the rotating seat 2, and attach the back pivot point 4
It is pivoted by. The rear part of the seat 5 is pivotally connected to the rotating seat 2 by the seat pivot point 6 in front of the back pivot point 4, and the front part is supported by the support 29 at the front of the rotating seat 2. Keep it almost horizontal.

定台１に設られた後制限片である。The lever 22 is moved forward by a spring 25, for example. However, instead of the spring 25, the front end 19 may be made heavier. The shape of the oblique portion 26 is appropriate to suit its function. 27 is front end 1
9 is a front restricting piece provided on the fixed base 1 at a position to the left of the front restricting piece 27, and 28 is a rear restricting piece provided on the fixed base 1 just behind the front restricting piece 27.
本発明はこのような構成を有するもので、その作用およ
び効果は次のようである。The present invention has such a configuration, and its functions and effects are as follows.
第１図は座席として使用される状態、すなわち展開状態
を示しているが、この状態では前端１９が前ストッパ片
１３と係合しており、また左側には前制限片２７がある
ので回動座２は回動することなく、座席として普通に使
用される。FIG. 1 shows the state in which it is used as a seat, that is, the unfolded state. In this state, the front end 19 is engaged with the front stopper piece 13, and there is a front limiter piece 27 on the left side, so the rotation is not possible. The seat 2 does not rotate and is normally used as a seat.
座当５は下枢着点６と支柱２９とに支えられているので
、座乗者の荷重にたえる。Since the seat rest 5 is supported by the lower pivot point 6 and the support column 29, it can withstand the load of the seat occupant.
背当３は上枢着点７が下枢着点８にリンク９により連結
され、背枢着点４により枢着されているので、座乗者の
背による荷重にたえる。The back support 3 has an upper pivot point 7 connected to a lower pivot point 8 by a link 9, and is pivoted at the back pivot point 4, so it can withstand the load from the back of the seat occupant.
すなわち展開状態で座席としての作用を安定してはたす
ことができる。In other words, it can stably function as a seat in the unfolded state.
本発明を回動するには、次のようにする。To rotate the invention, proceed as follows.
座当５を座枢着点６まわりに上方に回動すると、下枢着
点８はリンク９を介して上枢着点７を引張り、背当３は
背枢着点４まわりに前方に回動して第３図のように座当
５と背当３とが密着した状態で立つ。When the seat rest 5 is rotated upward around the seat pivot point 6, the lower pivot point 8 pulls the upper pivot point 7 through the link 9, and the back rest 3 is rotated forward around the back pivot point 4. The user moves to stand with the seat rest 5 and back rest 3 in close contact with each other as shown in Fig. 3.
この状態において座当５は重力で後にたおれる傾向にあ
り、また背当３は重力により前にたおれる傾向にあるの
で、また、座当５と背当３との間には摩擦が存在するの
で、この立つた状態でほぼ安定にすることができるもの
であるが、適宜の保持機構を付加してもよい。座当５が
上方に回動する途中において座当５の後下端２１がレバ
ー２２の後部上面を下方へ押さえこみ、したがつて前端
１９には上方に動いて前ストッパ片１３との係合が解放
された状態になる。In this state, the seat rest 5 tends to fall backwards due to gravity, and the back rest 3 tends to fall forward due to gravity, and since there is friction between the seat rest 5 and the back rest 3, Although it can be made almost stable in this standing state, an appropriate holding mechanism may be added. During the upward rotation of the seat stop 5, the rear lower end 21 of the seat rest 5 presses down the rear upper surface of the lever 22, so that the front end 19 moves upward and engages with the front stopper piece 13. become liberated.
立てた状態の座当５または背当３などを持ち回動座２と
共に上から見て反時計方向にまわし、前端１９が後制限
片２８に当たつた位置において座当５を水平にもどすと
、背当３はリンク９の作用で適当にたおれ、また後下端
２１はレバー２２を押さなくなるので、前端１９は後ス
トッパ片１７に係合して座席は回動しなくなり、座席と
して使用状態となるものであり、すなわちここで座席の
転換ができたことになる。Hold the seat rest 5 or the back rest 3 in an upright position and turn it together with the rotating seat 2 counterclockwise when viewed from above, and return the seat rest 5 to the horizontal position at the position where the front end 19 touches the rear restriction piece 28. , the backrest 3 is properly folded down by the action of the link 9, and the rear lower end 21 no longer pushes the lever 22, so the front end 19 engages with the rear stopper piece 17 and the seat no longer rotates, leaving the seat in use. This means that the seat can be changed at this point.
転換の過程においては、座当５、背当３は立つているの
で、回動のまわりに出張つていることがなく、回動する
ためのスペースが小ですみ、回動しやすいものである。During the conversion process, the seat rest 5 and the back rest 3 are standing, so they do not protrude around the rotation, require a small space for rotation, and are easy to rotate.
斜部２６は、後下端２１がレバー２２を押さえこみやす
くなるのに役立つ。前端１９が後ストッパ片１７に係合
した展開状態から転換しようとするときは、前と同様に
座当５をはね上げて背当３と共に立て、前端１９の係合
を解放して回動し、転換することができる。The oblique portion 26 helps the rear lower end 21 to easily press the lever 22. When the front end 19 is to be changed from the deployed state engaged with the rear stopper piece 17, the seat rest 5 is raised to stand together with the back rest 3 as before, the front end 19 is released from the engagement, and rotated. Can be converted.
展開状態から折畳状態にするのに、座当５をはね上げる
かわりに背当３を持ち上げてリンク９により座当５の後
下端２１を押して座当５を立てるようにすることもでき
る。座当５、背当３は、それらを構成するのに必要な枠
等を含み得る。In order to change the unfolded state to the folded state, instead of flipping up the seat rest 5, the back rest 3 can be lifted up and the rear lower end 21 of the seat rest 5 is pushed by the link 9 to make the seat rest 5 stand up. The seat support 5 and the back support 3 may include frames and the like necessary for constructing them.
本発明によれば、座席の回動に必要なスペースをせまく
することによつて従来の第一欠点を除去することができ
、また座当を上方に折畳むことによつてそれまで固定状
態にあつた座席を回動自在にし、また折畳まれていた座
当を下方に展関することによつてそれまで回動自在であ
つた座席を固定状態にするようにすることによつて従来
の第二欠点を除去することができるものである。According to the present invention, the first drawback of the conventional method can be eliminated by reducing the space required for rotating the seat, and by folding the seatrest upward, it is possible to prevent the seat from being in a fixed state until then. By making the seat rotatable, and by extending the seat that had been folded downward, the seat, which had previously been rotatable, was fixed. It can eliminate two defects.
以上の如くにして本発明は、従来の欠点の除去された回
動転換座席を提供するものであり、産業上価値大である
。As described above, the present invention provides a rotary convertible seat that eliminates the drawbacks of the prior art, and is of great industrial value.
