Description

本発明は、椅子の座面を前後に傾斜できるようにした起立補助椅子に関するものである。 The present invention relates to an upright auxiliary chair in which the seat surface of the chair can be tilted back and forth.

着座している人の起立を補助するため座面を分割して前後に傾斜できるようにした椅子が知られている（例えば特許文献１参照）。特許文献１に記載の椅子は、座板を座面前部支持リンクと座面後部支持リンクによって支承し、座面前部支持リンクと座面後部支持リンクを連結ピンで回動自在に連結し、座面後部支持リンクをアクチュエータで上方に回動することにより座面前部支持リンクを前傾させ、座面後部支持リンクをそれより後方に屈曲し、着座者の臀部を押し上げるよう構成されている。このように、座部を前座部と後座部に分離した従来の椅子は、座面前部支持リンクと座面後部支持リンクのそれぞれ上面に前座部と後座部を一体的に形成した構造である。 A chair is known in which the seat surface is divided so that the seat can be tilted back and forth in order to assist the seated person in standing up (see, for example, Patent Document 1). In the chair described in Patent Document 1, the seat plate is supported by the seat surface front support link and the seat surface rear support link, and the seat surface front support link and the seat surface rear support link are rotatably connected by a connecting pin, and the seat is seated. The seat surface front support link is tilted forward by rotating the surface rear support link upward by an actuator, the seat surface rear support link is bent rearward, and the buttocks of the seated person are pushed up. In this way, the conventional chair in which the seat portion is separated into the front seat portion and the rear seat portion has a structure in which the front seat portion and the rear seat portion are integrally formed on the upper surfaces of the seat surface front support link and the seat surface rear support link, respectively. be.

上記の構成により、特許文献１に記載の椅子では、座面前部支持リンクと座面後部支持リンクを回動して傾斜させる際、上記前座部の後部上端と後座部の前部上端間の間隔は、連結ピン部分を中心として離れ、大きな隙間が生じる。また、前座部と後座部の上面にわたってクッション材や表皮を連続して設けた構造であると、前座部と後座部が傾斜するとき前座部と後座部の上端間に生じた隙間部分でクッション材や表皮が引っ張られたり、着座したときに挟み込まれて、損傷しやすい。そのため、従来の椅子では、座板にクッション材や表皮を設ける場合、前座部と後座部にそれぞれ別々にクッション材や表皮を設け、この前座部と後座部をそれぞれ前部支持リンクと後部支持リンンクに固定しているので、上記のようにして生じた隙間が表面に現れ、この隙間に衣服や手指を挟む込むおそれがあり、良好な使用感が得られない。 With the above configuration, in the chair described in Patent Document 1, when the seat surface front support link and the seat surface rear support link are rotated and tilted, between the rear upper end of the front seat portion and the front upper end of the rear seat portion. The spacing is centered on the connecting pin portion, and a large gap is created. Further, if the structure is such that the cushion material and the skin are continuously provided over the upper surfaces of the front seat portion and the rear seat portion, the gap portion generated between the upper ends of the front seat portion and the rear seat portion when the front seat portion and the rear seat portion are inclined. The cushioning material and the epidermis are pulled or pinched when seated, and are easily damaged. Therefore, in the conventional chair, when the cushion material and the skin are provided on the seat plate, the cushion material and the skin are separately provided on the front seat and the rear seat, and the front and rear seats are provided with the front support link and the rear, respectively. Since it is fixed to the support link, the gap generated as described above appears on the surface, and there is a possibility that clothes or fingers may be caught in this gap, and a good usability cannot be obtained.

特開平１０－２９５７３１号公報（特許請求の範囲、段落０００９，００１０、図面）JP-A-10-295731 (Claims, paragraphs 0009, 0010, drawings)

本発明の解決課題は、椅子の座を前座部と後座部に分割して前座部と後座部を前後に傾斜できるようにした椅子において、前座部と後座部を傾斜させた際、前座部の後端と後座部の前端間に生じる隙間を、従来のように前座部と後座部を独立してそれぞれの支持フレームに固定した椅子に比べてより少なくし、前座部と後座部にわたってクッション材や表皮を設けても損傷しにくく、衣服や手指の挟み込みを防止できるようにした起立補助椅子を提供することである。 The problem to be solved by the present invention is that in a chair in which the seat of the chair is divided into a front seat portion and a rear seat portion so that the front seat portion and the rear seat portion can be tilted back and forth, when the front seat portion and the rear seat portion are tilted. The gap between the rear end of the front seat and the front end of the rear seat is smaller than that of a chair in which the front seat and the rear seat are independently fixed to the respective support frames as in the conventional case. It is an object of the present invention to provide an upright assisting chair that is not easily damaged even if a cushioning material or a skin is provided over the seat portion and can prevent clothes or fingers from being pinched.

本発明によれば、椅子の座部に前部を枢着した座前部材と、該座前部材の後部に枢着した摺動フレームと、上記座前部材と摺動フレームを上方に回動させる駆動手段と、該摺動フレームの回動位置を規制する制御リンクと、座前部材に固定した前座部と、該前座部に枢着した後座部を有し、上記後座部は、上記摺動フレームが回動する際、摺動フレームに沿って前後方向に摺動するよう連結部材で摺動フレームに連結されていることを特徴とする起立補助椅子が提供され、上記課題が解決される。 According to the present invention, the seat front member pivotally attached to the seat portion of the chair, the sliding frame pivotally attached to the rear portion of the seat front member, and the seat front member and the sliding frame are rotated upward. The rear seat portion has a driving means for causing the sliding frame, a control link for restricting the rotation position of the sliding frame, a front seat portion fixed to the seat front member, and a rear seat portion pivotally attached to the front seat portion. An upright auxiliary chair characterized in that the sliding frame is connected to the sliding frame by a connecting member so as to slide in the front-rear direction along the sliding frame when the sliding frame rotates is provided, and the above-mentioned problems are solved. Will be done.

また、本発明によれば、椅子の座部には椅子フレームが固定され、上記座前部材は前座部の座前芯板を固定する板状の本体を有し、該本体の前端には、椅子フレームに枢着するための前方ヒンジが設けられ、後端には摺動フレームを枢着するための後方ヒンジが設けられ、上記連結部材は摺動フレームに嵌着するよう略Ｕ字状に形成されている上記起立補助椅子が提供される。 Further, according to the present invention, the chair frame is fixed to the seat portion of the chair, and the seat front member has a plate-shaped main body for fixing the seat front core plate of the front seat portion, and the front end of the main body has a plate-shaped main body. A front hinge for pivoting to the chair frame is provided, a rear hinge for pivoting the sliding frame is provided at the rear end, and the connecting member is substantially U-shaped so as to be fitted to the sliding frame. The above-mentioned standing auxiliary chair formed is provided.

本発明は、上記のように構成され、駆動手段により座前部材と摺動フレームを回動させると、座前部材に固定された前座部は座前部材とともに前傾する。摺動フレームも座前部材とともに回動するが、制御リンクにより所定位置で回動が停止する。このとき摺動フレームに連結部材で摺動可能に連結した後座部は、傾斜しながら上記前座部に引かれて前進するから、従来のように前座部と後座部をそれぞれ前後の支持リンクと一体的に固定した場合に比べて、前座部の後部上端と後座部の前部上端間に大きな隙間が生じないようにできる。その結果、前座部と後座部にわたってクッション材を設けても損傷することが少なくなる。また、上記後座部は連結部材により摺動フレームに摺動可能に連結されているので、該摺動フレームから分離しないようにでき、椅子を搬送するときにバタバタすることもなく、取り扱いやすい。 The present invention is configured as described above, and when the seat front member and the sliding frame are rotated by the driving means, the front seat portion fixed to the seat front member tilts forward together with the seat front member. The sliding frame also rotates with the seat member, but the rotation is stopped at a predetermined position by the control link. At this time, the rear seat portion slidably connected to the sliding frame by the connecting member is pulled forward by the front seat portion while tilting, so that the front seat portion and the rear seat portion are supported links in the front and rear, respectively, as in the conventional case. It is possible to prevent a large gap from being generated between the upper end of the rear portion of the front seat portion and the upper end of the front portion of the rear seat portion as compared with the case where the front seat portion is integrally fixed. As a result, even if the cushion material is provided over the front seat portion and the rear seat portion, it is less likely to be damaged. Further, since the rear seat portion is slidably connected to the sliding frame by a connecting member, it can be prevented from being separated from the sliding frame, and it is easy to handle without fluttering when transporting the chair.

上記椅子１は、前座部３０と後座部３２が水平位置にある着座状態から、駆動手段のロックを解除すれば、座前部材９と摺動フレーム１６の後部が駆動手段で押し上げられ、前方ヒンジ１１部分を中心として回動し、座前部材９と摺動フレーム１６は前傾し、かつ後方ヒンジ１８部分を中心として摺動フレーム１６が屈曲し、着座者の臀部を押し上げ、起立を補助することができる。そして、前座部３０は座前部材９と一緒に大きく前傾するが、後座部３２は座ヒンジ３７部分で屈曲するとともに前座部３０に引っ張られ、摺動フレーム１６に沿って摺動可能であるから、摺動フレーム１６に対する相対位置が、水平状態のときの位置よりも前進する。そのため、傾斜状態における前座部３０と後座部３２の上端間の間隙は、従来のように前座部を座面前部支持リンクに固定しかつ後座部を座面後部支持リンクに固定し支持リンクに対して座部の相対位置を不変に設けた椅子よりも少なくすることができる。これにより、座部にクッション材を設けても損傷しにくくすることができる。 In the chair 1, if the lock of the drive means is released from the seated state where the front seat portion 30 and the rear seat portion 32 are in the horizontal position, the rear portion of the seat front member 9 and the sliding frame 16 is pushed up by the drive means. The front hinge 11 rotates around the front hinge 11, the seat front member 9 and the sliding frame 16 tilt forward, and the sliding frame 16 bends around the rear hinge 18 portion, pushing up the buttocks of the seated person and standing up. Can be assisted. Then, the front seat portion 30 is greatly tilted forward together with the seat front member 9, but the rear seat portion 32 is bent at the seat hinge 37 portion and pulled by the front seat portion 30 so as to be slidable along the sliding frame 16. Therefore, the relative position with respect to the sliding frame 16 advances from the position in the horizontal state. Therefore, the gap between the upper ends of the front seat portion 30 and the rear seat portion 32 in the inclined state is such that the front seat portion is fixed to the seat surface front support link and the rear seat portion is fixed to the seat surface rear support link as in the conventional case. The relative position of the seat can be made smaller than that of a chair provided invariantly. As a result, even if a cushion material is provided on the seat portion, it can be prevented from being damaged.
