次に、本実施例における座3の高さ等について説明する。
前記座3を、図12に示すように、左右の側枠2、2における最上位の位置の座取付穴13A、13Bに対して取り付けた場合、すなわち、座3が最上位となる位置に取り付けた場合には、座3の上面(以下、座面ともいう)3aは、図1、図2に示すように若干湾曲しているが、座面3aの前後方向の水平面に対する角度(以下、座面3aの傾斜角度という)が略0度、すなわち、座面3aが略水平に、座面3aの前方の高さが、その後方の高さと略同じに設定されている。また、座面3aの左右方向の中央における最上位点から床面までの高さ(以下、座面3aの高さともいう)が520mmに設定され、背4の前面における左右方向の中央線の延長線が、座面3aと交わる位置から座面3aにおける最前端までの長さ(以下、座面3aの奥行きともいう)が310mmとなるように設定されている。
Next, the height of the seat 3 in the present embodiment will be described.
As shown in FIG. 12, when the seat 3 is attached to the seat mounting holes 13A and 13B at the uppermost position in the left and right side frames 2 and 2, that is, the seat 3 is attached at the uppermost position. In this case, the upper surface 3a of the seat 3 (hereinafter also referred to as a seat surface) 3a is slightly curved as shown in FIGS. 1 and 2, but the angle of the seat surface 3a with respect to the horizontal plane (hereinafter referred to as the seat surface). The inclination angle of the surface 3a) is set to approximately 0 degrees, that is, the seating surface 3a is set to be substantially horizontal, and the front height of the seating surface 3a is set to be substantially the same as the rear height. Further, the height from the highest point in the center of the seat surface 3a to the floor (hereinafter also referred to as the height of the seat surface 3a) is set to 520 mm, and the center line of the left and right direction on the front surface of the back 4 is set. The length of the extension line from the position where it intersects the seat surface 3a to the foremost end of the seat surface 3a (hereinafter also referred to as the depth of the seat surface 3a) is set to 310 mm.

前記座3を、図13に示すように、左右の側枠2、2における夫々の上から2つ目に位置する座取付穴13A、13Bに対して取り付けた場合、すなわち、座3が2番目に高い位置となるように取付けた場合には、座面3aは後方に向って下降し、座面3aの傾斜角度θが1度、座面3aの高さが490mm、座面3aの奥行きが350mmとなるように設定されている。   As shown in FIG. 13, when the seat 3 is attached to the seat attachment holes 13A and 13B located at the second position from the top of the left and right side frames 2 and 2, that is, the seat 3 is second. When the seating surface 3a is mounted at a high position, the seating surface 3a descends backward, the inclination angle θ of the seating surface 3a is 1 degree, the height of the seating surface 3a is 490 mm, and the depth of the seating surface 3a is It is set to be 350 mm.

前記座3を、図14に示すように、左右の側枠2、2における夫々の上から3つ目に位置する座取付穴13A、13Bに対して取り付けた場合、すなわち、座3が3番目に高い位置となるように取付けた場合には、座面3aは後方に向って下降し、座面3aの傾斜角度θが2度、座面3aの高さが460mm、座面3aの奥行きが370mmとなるように設定されている。   As shown in FIG. 14, when the seat 3 is attached to the seat attachment holes 13A and 13B located at the third position from the top of each of the left and right side frames 2 and 2, that is, the seat 3 is third. When the seating surface 3a is mounted at a high position, the seating surface 3a descends rearward, the inclination angle θ of the seating surface 3a is 2 degrees, the height of the seating surface 3a is 460 mm, and the depth of the seating surface 3a is It is set to be 370 mm.

前記座3を、図3に示すように、左右の側枠2、2における夫々の上から4つ目に位置する座取付穴13A、13Bに対して取り付けた場合、すなわち、座3が最下位の位置となるように取付けた場合には、座面3aは後方に向って下降し、座面3aの傾斜角度θが3度、座面3aの高さが430mm、座面3aの奥行きが390mmとなるように設定されている。   As shown in FIG. 3, when the seat 3 is attached to the seat mounting holes 13A and 13B located at the fourth position from the top of the left and right side frames 2 and 2, that is, the seat 3 is at the lowest position. When the seating surface 3a is mounted so as to be in the position, the seating surface 3a is lowered rearward, the inclination angle θ of the seating surface 3a is 3 degrees, the height of the seating surface 3a is 430 mm, and the depth of the seating surface 3a is 390 mm. It is set to become.

以上のように、前記座面3aは、座3が最上位に位置する場合においては、座面3aは略水平であり、座面3a傾斜角度θが略0度、すなわち、座面3aの前方の高さが、その後方の高さと略同じであるが、座3を最上位から1段下げるごとに、座面3aの左右の両端部で形成される面の水平面に対する角度(座面3aの傾斜角度)が大きくなるように設定されている。すなわち、前記座3の高さの位置が低くなるほど、座面3aの後方が下がるとともに、座面3aの傾斜角度θが1度、2度、3度と徐々に大きくなる。   As described above, when the seat 3 is positioned at the uppermost position, the seat surface 3a is substantially horizontal, and the seat surface 3a tilt angle θ is substantially 0 degrees, that is, the front of the seat surface 3a. The height of the seat surface 3a is substantially the same as the height behind it, but each time the seat 3 is lowered by one step from the top, the angle of the surface formed by the left and right ends of the seat surface 3a with respect to the horizontal plane (the seat surface 3a (Inclination angle) is set to be large. That is, the lower the position of the seat 3 is, the lower the back of the seat surface 3a is, and the inclination angle θ of the seat surface 3a is gradually increased to 1 degree, 2 degrees, and 3 degrees.

また、前記前側フレーム7bにおける座取付穴13Aの位置が、上側ほど後方に、下側ほど前方に位置するように設定され、その座取付穴13Aの位置に、前側取付穴16を対応させて座3を取付けるため、前記座3の高さの位置が高いほど座面3aの奥行きが狭くなる。すなわち、前記椅子1における座3の最前端の位置が、座3の高さの位置が高いほど、後方に位置するように設定されている。   Further, the seat mounting hole 13A in the front frame 7b is set so that the upper side is positioned rearward and the lower side is positioned forward, and the seat mounting hole 13A is associated with the front mounting hole 16 in the seat. 3 is attached, the depth of the seat surface 3a becomes narrower as the height of the seat 3 is higher. That is, the position of the foremost end of the seat 3 in the chair 1 is set to be located rearward as the height of the seat 3 is higher.

以上の構成により、本発明の実施例の椅子1は、次のような作用、効果を発揮する。
前記座面3aは、前記座3の高さの位置が低くなるほど、座面3aの傾斜角度θが大きくなるように設定されていることにより、使用者の成長によるデスクにおける作業内容の変化に対応した座面の角度とすることができる。例えば、小学生時は、ほとんど勉強のみであるため勉強に打ち込めるよう身体の若干の前傾姿勢がとれる座面3aの傾斜角度に、社会人になるほど、パソコンやその他様々な作業をする際に楽な姿勢となる座面3aの傾斜角度に設定することができる。
With the above configuration, the chair 1 according to the embodiment of the present invention exhibits the following actions and effects.
The seating surface 3a is set so that the inclination angle θ of the seating surface 3a becomes larger as the height of the seating 3 becomes lower, thereby responding to changes in work contents at the desk due to the growth of the user. The angle of the seating surface can be set. For example, when you are an elementary school student, because you are mostly studying only, the inclination angle of the seat surface 3a that allows you to take a slight forward leaning posture so that you can focus on studying is so easy that you become a member of society and work more easily with a personal computer and various other work The inclination angle of the seating surface 3a that becomes the posture can be set.

また、前記椅子1における座面3aの最前端の位置が、前記座3の高さの位置が高いほど、後方に位置する。すなわち、使用者の身長が低い時ほど、座面3aの奥行きが狭くなり、座面3aの奥行きを、身長の変化に適応させることができる。   Further, the position of the foremost end of the seat surface 3a in the chair 1 is located rearward as the height of the seat 3 is higher. That is, as the user's height is lower, the depth of the seating surface 3a becomes narrower, and the depth of the seating surface 3a can be adapted to changes in height.

人間工学においては、ダイニングテーブルやデスクの高さに対する適正な椅子の座面の高さは、差尺(=テーブルの天板の上面の高さ−椅子の座面の高さ)を用いて導き出され、
読書をする場合の椅子の座面の高さは、デスク差尺 = 座高 × 1/3となる高さが良いとされ、
筆記をする場合の椅子の座面の高さは、デスク差尺 = 座高 × 1/3 − 2〜3cmとなる高さが良いとされている。
In ergonomics, the appropriate chair seat height relative to the height of the dining table or desk is derived using a differential scale (= height of the top surface of the table top-height of the chair seat). And
