の背凭れ傾倒装置によってなされる。According to the present invention, in order to eliminate the above-mentioned drawbacks of the conventional chair which can be tilted on a backrest, only the lifting device is interposed between the seat and the base, and the minimum height of the seat is lowered. To make it easier to sit. The means is a seat part whose upper and lower positions can be selected by a lifting device provided under the seat part, armrests provided on the left and right of the seat part, and the seat part. In a backrest tilting device of a chair, which comprises a backrest provided to be capable of ups and downs, a undulating substrate is provided at a position on the left and right of a substrate fixed above the lifting device and below an armrest,
On one of the undulating boards, a base bracket is erected forward and a support bracket is erected rearward, and an undulating link for undulating the backrest is provided between the armrest end and the undulating board end at the lower end position of the backrest. The base end bracket pivotally supports one end of a cylinder, and the support bracket pivotally supports a substantially intermediate position of the undulating link. , The rear end position of the armrest that connects the moving end of the cylinder and the support bracket and the undulating link are pivotally supported, and the undulations located between the hand rubbing cover and the lower end of the backrest. This is done by a backrest tilting device of a hairdressing and beauty chair characterized by arranging a bellows that covers the link.
本発明の背凭れ傾倒装置においては、座部の左右に設け
られ、座部と背凭れを連結する起伏手段の動作によって
背凭れを後方に傾倒したり、前方に起立させたりするこ
とができるものであるが、座部と基台との間には起伏手
段がなくなるので、座部の初高の最低高さは、昇降装置
によってのみ限定されるものとなる。In the backrest tilting device of the present invention, the backrest can be tilted backward or raised forward by the operation of the undulating means that is provided on the left and right of the seat portion and connects the seat portion and the backrest. However, since there is no undulating means between the seat portion and the base, the minimum height of the seat portion is limited only by the lifting device.
従って、初高を低くして座部に腰掛け易くすることがで
きるものである。Therefore, the initial height can be lowered to make it easier to sit on the seat.
本発明の実施の一例を、図面について以下に説明する。 An example of implementation of the present invention will be described below with reference to the drawings.
図面において、Ａは肘掛けとなる手摺り、Ｂは座部とな
るシート、Ｃは背凭れである。In the drawing, A is a handrail that serves as an armrest, B is a seat that serves as a seat, and C is a backrest.
シートＢは、基台上に配置されてシートＢを昇降させる
ための昇降装置の上端に固定される基板１上に設けられ
ている。The sheet B is provided on a substrate 1 which is arranged on a base and fixed to an upper end of an elevating device for elevating the sheet B.
この基板１の左右には起伏基板２が取付けられ、この起
伏基板２に固定されている支持ブラケット７に、背凭れ
Ｃを取付けた起伏リンク６が支軸８によって回動自在に
取付けられ、背凭れＣはシートＢに対して起伏可能とな
っている。An undulating board 2 is attached to the left and right of the board 1, and an undulating link 6 to which a backrest C is attached is rotatably attached by a support shaft 8 to a support bracket 7 fixed to the undulating board 2. The lean C can be raised and lowered with respect to the sheet B.
左右の起伏基板２のうち、一方の起伏基板２には基端ブ
ラケット３が固定されていて、これには油圧シリンダ４
の基端が支軸９によって回動可能に取付けられ、油圧シ
リンダ４のラム５の先端には、その側の起伏リンク６の
一端が支軸10で取付けられている。A base bracket 3 is fixed to one of the left and right undulating boards 2, and a hydraulic cylinder 4 is attached to this.
A base end of the hydraulic cylinder 4 is rotatably attached by a support shaft 9, and one end of an undulating link 6 on the side of the ram 5 of the hydraulic cylinder 4 is attached by a support shaft 10.
このシリンダ４、ラム５、支持ブラケット７等は、手摺
りカバー11で被覆すると共に、手摺りカバー11と背凭れ
Ｃとの間で露出する起伏リンク６を蛇腹12で覆って、こ
れ等の起伏手段や蝶着手段が外から見えないようにして
いる。The cylinder 4, the ram 5, the support bracket 7, and the like are covered with a handrail cover 11, and the undulating links 6 exposed between the handrail cover 11 and the backrest C are covered with a bellows 12 so that these undulations are provided. The means and the hinged means are hidden from the outside.
この背凭れ傾動装置は、油圧シリンダ４内に圧力が導入
されて、ラム５が伸長すると、起伏リンク６は支軸10が
押されるので、背凭れＣを起立させる方向に回動し、背
凭れＣは起立状態となる。In this backrest tilting device, when pressure is introduced into the hydraulic cylinder 4 and the ram 5 extends, the undulating link 6 pushes the support shaft 10, so that the backrest C rotates in the direction in which the backrest C stands up and the backrest tilts. C is in a standing state.
反対に、油圧シリンダ４内の圧力が導出されてラム５が
収縮すると、支軸10が手前に引かれるために、起伏リン
ク６は反対方向に回動し、背凭れＣは傾倒状態となるも
のである。On the contrary, when the pressure in the hydraulic cylinder 4 is derived and the ram 5 contracts, the support shaft 10 is pulled toward the front, so that the up-and-down link 6 rotates in the opposite direction, and the backrest C is tilted. Is.
本発明は叙上のように、背凭れを傾倒する起伏手段は肘
掛けの内部に収納されて、外部からは見えないので、椅
子の体裁を損ずることがなく、且つ肘掛けの巾は或る程
度広くなるので、これに掛けた肘が外れることなく、安
定して掛けることができる。According to the present invention, since the undulating means for tilting the backrest is housed inside the armrest and is not visible from the outside as in the above, it does not spoil the appearance of the chair and the width of the armrest is wide to some extent. Therefore, the elbows hung on this can be stably hung without coming off.
そして、この起伏手段を座部と基台との間に設置する必
要がなくなるため、起伏手段に要した分だけ椅子の初高
を低くすることができ、座部に容易に腰掛けることがで
きるようになる。Since it is not necessary to install the undulating means between the seat and the base, the initial height of the chair can be lowered by the amount required for the undulating means, and the seat can be easily seated. become.
同時に、座部の下部に起伏手段がないことによって、座
部の下方はスッキリとさせることができ、デザインの多
様化が図れ、さらに、シリンダと支持ブラケットおよび
起伏リンクから構成されているので、構成が簡単でコス
トの低減が図れる等の効果を有するものである。At the same time, since there is no undulating means at the bottom of the seat, the lower part of the seat can be made clearer, the design can be diversified, and the cylinder, the support bracket, and the undulating link are included. It has advantages such as that it is simple and the cost can be reduced.
