Description
【０００１】[0001]
本考案は、着座する人の体形に応じて背もたれ部の高さと座部の広さを同時に 調節できる椅子の背もたれ調節装置に関する。 BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a chair backrest adjusting device capable of adjusting the height of the backrest and the width of the seat at the same time according to the body shape of a seated person.
【０００２】[0002]
従来は、座部と、該座部を支持する脚部と、前記座部または脚部により支持す る背もたれ部とからなる椅子において、背もたれ部を前後方向にクッションをも たせて上下方向にのみ調節することは知られている。 Conventionally, in a chair including a seat portion, a leg portion supporting the seat portion, and a backrest portion supported by the seat portion or the leg portion, a backrest portion is provided with a cushion in the front-rear direction and only in the vertical direction. It is known to regulate.
【０００３】[0003]
しかしながら、そのように背もたれ部の高さ調節のみしか行なえず、また、背 もたれ部は体重をのせて前後方向にクッションをもたせるだけであって座部の広 さを変えることができず、着座する人の体形に充分、対応しきれない、といった 不具合を呈している。 However, in this way, only the height of the backrest can be adjusted, and the seatback cannot be changed by simply putting weight on the backrest and cushioning it in the front-back direction. It has a problem that it cannot respond to the human body shape enough.
【０００４】[0004]
本考案は、そのような不具合を解決し、簡単な構造にして好適に実施できるよ う工夫したものであり、そのため、座部の後部または脚部の上部後方には前低後 高に傾斜する幅広の嵌合保持体を形成し、該嵌合保持体に摺動自在に嵌合する支 持体の上部には、直立した背もたれ部の下部を彎曲したア−ムを介して一体的に 形成し、前記嵌合保持体に嵌挿するノブ付きねじを前記支持体の中央側長孔に嵌 挿するとともに支持体を嵌合保持体に締付可能にして構成したものである。 The present invention has been devised so as to solve such a problem and to be suitably implemented with a simple structure. Therefore, the rear part of the seat part or the upper rear part of the leg part is inclined to the front low rear high. A wide fitting holder is formed, and the upper part of the holder that slidably fits into the fitting holder is integrally formed with an upright backrest part through a curved arm. Then, a screw with a knob to be fitted into the fitting holder is fitted into the central elongated hole of the supporting body, and the supporting body can be fastened to the fitting holding body.
【０００５】[0005]
したがって、ねじを弛めて締付けを解除し、ねじを長孔内に摺動させながら支 持体を嵌合保持体に摺動させると、背もたれ部を前後動および上下動させること ができることになり、そのままねじを締付けると、背もたれ部の高さ調節と座部 の前後方向広さを調節できる。 Therefore, by loosening the screw to release the tightening, and sliding the support body to the fitting support body while sliding the screw in the long hole, the backrest can be moved back and forth and up and down. , If you just tighten the screws, you can adjust the height of the backrest and the width of the seat in the front-rear direction.
【０００６】[0006]
図１は椅子全体の側面図を示し、下部に５つのキャスタ−６を有する脚部Ｂの 上部に座部Ａを装着して従来形構造同様に構成し、該座部Ａの後部には前低後高 に角度θだけ傾斜する幅広の嵌合保持体１を固設するが、該嵌合保持体１は、中 央に突然７を有する凹溝部８の両側に突条部９、９をおいて凹溝部１０、１０を 形成した保持板１ａと、平板の保持板１９とを合着して構成し、前記保持板１ａ および１９の中心部に形成した孔１１およびねじ孔１２にはノブ４ａ付きねじ４ を挿着するとともに、該ねじ４の先端に形成した孔１３には抜け止め用のスナッ プピン１４を挿着して構成する。 FIG. 1 shows a side view of the entire chair, which has a leg portion B having five casters 6 on the lower portion thereof and a seat portion A mounted on the upper portion of the chair to have the same structure as the conventional structure. A wide fitting holder 1 that is inclined at an angle θ at a low rear height is fixed, but the fitting holder 1 has ridges 9 and 9 on both sides of a concave groove 8 having a sudden 7 in the center. The holding plate 1a having the recessed grooves 10 and 10 and the flat holding plate 19 are attached together, and the holes 11 and the screw holes 12 formed in the central portions of the holding plates 1a and 19 are provided with knobs. A screw 4 with a 4a is inserted and a snap pin 14 for retaining is inserted into a hole 13 formed at the tip of the screw 4.
【０００７】 また、前記嵌合保持体１に摺動自在に嵌合する幅広の支持体２の上部には、直 立した背もたれ部Ｃの下部を２本の彎曲したア−ム３、３を介して一体的に形成 し、前記支持体２には、前記保持板１ａの突条７、凹溝部８および凹溝部１０、 １０にそれぞれ嵌合できる凹溝部１５、突条部１６、１６および突条部１７、１ ７を形成するとともに、前記保持板１ａの突条部９、９に圧接することができて 高さ表示ができる目盛りを有した滑り止めの凹溝部１８、１８を形成し、前記凹 溝部１５には前記ねじ４が嵌挿できる長孔５を形成して構成するが、前記嵌合保 持体１は前記脚部Ｂの上部後方側に設けて構成することもできる。In addition, on the upper part of the wide support 2 slidably fitted to the fitting holder 1, two curved arms 3 and 3 are formed at the lower part of the upright backrest C. The support member 2 is formed integrally with the holding member 1a, and the support member 2 can be fitted into the protrusions 7, the recessed groove portions 8 and the recessed groove portions 10, 10 of the holding plate 1a, respectively. In addition to forming the ridges 17 and 17, the non-slip concave grooves 18 and 18 having scales that can be pressed against the ridges 9 and 9 of the holding plate 1a and can display the height are formed. The groove 15 is formed with a long hole 5 into which the screw 4 can be inserted, but the fitting holder 1 may be provided on the upper rear side of the leg B.
【０００８】 したがって、ねじ４を締付けておくと、突条部９、９が凹溝部１８、１８に圧 着されて背もたれ部Ｃを固定することができるとともに、彎曲したア−ム３、３ により背もたれ部Ｃのクッション性が有効に発揮されることになり、ねじ４を弛 めて締付けを解除し、ねじ４を長孔５内に摺動させながら支持体２を嵌合保持体 １に矢印イ方向に摺動させると、図１に示すように、背もたれ部Ｃの前後方向長 さをＬ1からＬ2に、また、高さをＨ1からＨ2に調節できることになり、そのまま ねじ４を締付けると、背もたれ部Ｃの高さ調節と座部Ａの前後方向広さを調節で きる。Therefore, when the screw 4 is tightened, the ridge portions 9 and 9 can be pressed against the groove portions 18 and 18 to fix the backrest portion C, and the curved arms 3 and 3 can be used. The cushioning property of the backrest portion C is effectively exerted, the screw 4 is loosened to release the tightening, and the support 2 is slid into the elongated hole 5 while the support 2 is attached to the fitting holder 1 by the arrow. When slid in the direction a, as shown in FIG. 1, the length of the backrest portion C in the front-rear direction can be adjusted from L 1 to L 2 and the height can be adjusted from H 1 to H 2 , and the screw 4 By tightening, you can adjust the height of the backrest C and the width of the seat A in the front-rear direction.
【０００９】[0009]
このように本考案は、ねじ４を弛めて締付けを解除し、ねじ４を長孔５内に摺 動させながら支持体２を嵌合保持体１に摺動させ、背もたれの高低調節をする際 背もたれが低いとそれにあわせ座面は狭くなる一方背もたれを高くした場合は、 それにあわせて図１に図示する如く背もたれは後上方に位置する様になると共に 背もたれ支持ア−ム３は大きく後方に彎曲形成されており該部が丁度引上げられ 占位することとなるので座面は非常に広くなる。そして背もたれ部の上下調節を すると同時に座面の広さも調節することができることになり、そのままねじ４を 締付けるだけで背もたれ部Ｃの高さ調節と座部Ａの前後方向広さを調節できるこ とになって、着座する人の体形に応じて簡単に調節できることになり、また、幅 広の嵌合保持体１により背もたれ部Ｃを強力に支持できるとともに支持体２の締 付けも堅固に行なうことができることになり、更に背もたれ部Ｃは彎曲したア− ム３によりクッションをもたせて良好に支持することを得て、容易に調節できる 簡単な構造にして好適に実施できる特長を有する。 As described above, the present invention loosens the screw 4 to release the tightening, slides the support 2 on the fitting holder 1 while sliding the screw 4 into the elongated hole 5, and adjusts the height of the backrest. When the backrest is low, the seating surface becomes narrower accordingly, but when the backrest is raised, the backrest will be positioned rearward and upward as shown in Fig. 1, and the backrest support arm 3 will be greatly rearward. The seat surface is very wide because it is curved and the part is just pulled up and occupied. Then, it is possible to adjust the height of the backrest C and the width of the seat A in the front-rear direction simply by tightening the screws 4 while adjusting the height of the backrest up and down. Therefore, it is possible to easily adjust according to the body shape of the seated person, and also the backrest portion C can be strongly supported by the wide fit holding body 1 and the support body 2 can be firmly tightened. Further, the backrest portion C has a cushion by the curved arm 3 so as to be well supported, and has an advantage that it can be easily adjusted and has a simple structure.
