Description
本発明は、座の前後方向への摺動範囲を調節する機能を備えた椅子に関する。 The present invention relates to a chair having a function of adjusting a sliding range of a seat in the front-rear direction.
従来より、脚柱の上端に取付けられた座板取付け部材に対して、座が上部に設置され、前後に摺動可能とされた座板を前記座板取付け部材の上方に設けた椅子が種々提案されている。
このような前後の摺動機構を有する椅子には、一般的に、座の摺動位置を前後方向で調節する調節機構が備えられている(特許文献1〜2参照)。
Conventionally, there are various chairs in which a seat is installed above the seat plate mounting member attached to the upper end of the pedestal, and a seat plate that can slide back and forth is provided above the seat plate mounting member. Proposed.
A chair having such a front / rear sliding mechanism is generally provided with an adjusting mechanism for adjusting the sliding position of the seat in the front / rear direction (see Patent Documents 1 and 2).
特許文献1に記載の椅子は、可動レールに設けられたレバー部材を、該可動レールの摺動方向と略平行な方向に設置された回動軸を中心として回動させることにより、レバー部材に設けられた係合部を、ガイドレールに設けられた被係合部に係合させる係合機構を備えることによって、ガイドレールに対する可動レールの摺動を制限するものである。
また、特許文献2に記載の椅子は、座シェルに設けられ、該座シェルに対して可撓性を有するレバー片に形成された係合突片を、座支持体に形成された被係合部に係合可能とする係合機構を備えることによって、座支持体に対する座シェルの摺動を制限するものである。
しかし、特許文献1〜2に記載の椅子に備えられた係合機構によって、座板取付け部材と座板との確実な係合をなすためには、座板取付け部材と座板との係合時及び解除時の「変位」を大きく採る必要が生じる。すなわち、切り欠き部から回動軸までの距離を長くする構成や、回動変位を大きくする必要がある。
ここで、切り欠き部から回動軸までの距離を長くする構成を採用した場合、摺動機構のボリュームが増大し、設置するためのスペースを多分に要し、結果として摺動機構の小型化を妨げる結果となっていた。
また、回動変位を大きくする場合には、操作量が増大し、握力を維持することが必要になるなど、操作性が悪くなる結果となっていた。特に、レバー部材の可撓性を利用して係合動作を行う特許文献2に記載の調節機構は、構造を簡略化させた結果として、確実な係合が行われない可能性が高く、操作性が低い。
したがって、操作性が高く、コンパクトな座の摺動機構を備えた椅子は未だ実現されておらず、その提供が望まれているのが現状である。
The chair described in Patent Document 1 allows the lever member provided on the movable rail to pivot on a pivot shaft installed in a direction substantially parallel to the sliding direction of the movable rail. By providing an engaging mechanism for engaging the provided engaging portion with the engaged portion provided on the guide rail, the sliding of the movable rail with respect to the guide rail is limited.
Moreover, the chair of patent document 2 is provided in the seat shell, The engagement protrusion formed in the lever piece which has flexibility with respect to this seat shell is made into the to-be-engaged formed in the seat support body. By providing an engagement mechanism that can be engaged with the portion, sliding of the seat shell with respect to the seat support is limited.
However, in order to make sure that the seat plate mounting member and the seat plate are engaged with each other by the engagement mechanism provided in the chair described in Patent Documents 1 and 2, the seat plate mounting member and the seat plate are engaged. It is necessary to take a large amount of “displacement” at the time of release and release. That is, it is necessary to increase the distance from the notch to the rotation axis and to increase the rotation displacement.
Here, when the configuration in which the distance from the notch to the rotating shaft is increased, the volume of the sliding mechanism increases, and a large space is required for installation, resulting in a reduction in the size of the sliding mechanism. It was the result that hindered.
In addition, when the rotational displacement is increased, the amount of operation increases, and it is necessary to maintain the gripping force, resulting in poor operability. In particular, the adjustment mechanism described in Patent Document 2 that performs the engagement operation by utilizing the flexibility of the lever member is highly likely to not be reliably engaged as a result of simplifying the structure. The nature is low.
Therefore, a chair having a high operability and a compact seat sliding mechanism has not been realized yet, and the provision of such a chair is desired.
本発明は、従来における諸問題を解決し、以下の目的を達成することを課題とする。即ち、本発明は、操作性が高く、コンパクトな座の摺動機構を備えた椅子を提供することを目的とする。 An object of the present invention is to solve various problems in the prior art and achieve the following objects.

また、前後方向に略直交する方向に移動するように設置された部材が、レバーだけであるため、部品点数が少なく、結果として組み立てが容易となる。
更に、引っかかっているものを引っ張るといった動作が行われるので、操作者に直感的な操作感を与えることができる。
なお、前記座板取付け部材に対する座板の前後方向の移動の態様としては、特に制限はなく、目的に応じて適宜選択することができ、例えば、前記座板取付け部材に対して座板が前後方向に摺動する態様が好ましい。同様に、前記レバーの移動の態様としては、特に制限はなく、目的に応じて適宜選択することができ、例えば、座板に対して前後方向に略直交する方向に摺動する態様が好ましい。
<2> 座板取付け部材の上面に、複数の溝部が側縁部に平行な方向に形成され、座板には、前記溝部に係合する突条が下面に形成され、前記溝部に対して前記突条が摺動することによって、前記座板取付け部材に対して前記座板が前後方向に摺動可能とされた前記<1>に記載の椅子である。
該<2>に記載の椅子においては、前記溝部をガイドとして前記突条が摺動するので、前記座板取付け部材に対して前記座板がスムーズに摺動し、使用者の使用感を快適にすることができる。
<3> 切り欠き部に対して係合片が係合する方向にレバーを付勢する弾性体が設けられた前記<1>から<2>のいずれかに記載の椅子である。
該<3>に記載の椅子においては、切り欠き部に対して係合片が係合する方向にレバーを付勢する弾性体が設けられたことによって、使用者がレバーを引っ張った後、該レバーを元の状態に戻す応力が発生するので、使用者は、前記レバーを引っ張るだけでよく、使用者の操作性が向上する。
<4> 側縁部方向に開口した開口部が座板に形成され、該開口部にレバーが収納されている前記<1>から<3>のいずれかに記載の椅子である。
該<4>に記載の椅子においては、前記座板の側縁部を開口して、前記レバーを収納する形態となるので、前記開口部を前記レバーの設置するためのスペースとして有効に利用することができる。
<5> 座板取付け部材は、座板に形成された突条と、該座板の側縁部に形成された爪部とによって、座板に対して摺動可能に挟持されている前記<1>から<4>のいずれかに記載の椅子である。
該<5>に記載の椅子においては、座板取付け部材の上面が、座板に形成された突条に当接し、座板取付け部材の側縁部の下面が、座板の側縁部に形成された爪部とに当接することによって、座板取付け部材が座板によって挟持されることとなるので、座板取付け部材に対して座板を摺動させる際に、該座板が容易に外れることがなく、スムーズに摺動させることができる。

FIG. 3A is an exploded perspective view showing a configuration of a seat plate and a lever attached to the seat plate in the present embodiment, and FIG. 3B shows a configuration when the lever is attached to the seat plate in the embodiment. It is a perspective view.
As shown in FIG. 3A, two to four ridges 21 are formed in the front-rear direction on the back surface of the seat plate 20 of the chair of this embodiment.
Further, a plurality of claw portions 22a projecting in opposite directions are formed on the side edge portions 22 and 22 on both sides of the seat plate 20 in the front-rear direction.
Further, the storage portion 23 is formed so as to divide the left side edge portion 22 of the seat plate 20 and the pair of protrusions 21 formed along the side edge portion 22 in a direction substantially orthogonal to each other. .
The storage portion 23 has a U-shaped elastic body abutting on the top surface for fixing and installing the elastic body 101 together with the elastic body abutting section 100c provided on the stored lever 100. A portion 23a and a holding member 23b for slidably holding the lever 100 are provided. The U-shape is formed so as to open in the direction opposite to the divided side edge 22.
On the other hand, the lever 100 is formed with a grip portion 100a bent at an L shape in a side view from the front or rear at one end. The lever 100 is installed in the storage portion 23 in a direction in which the grip portion 100a is bent toward the lower surface of the seat plate 20.
The other end portion of the lever 100 is formed with a storage portion 100d that opens at least in a direction opposite to the direction in which the grip portion 100a bends.
The elastic body 101 is housed in the housing portion 100 d of the lever 100, and the side surface (elastic body contact portion 100 c) on the other end side of the storage portion 100 d and the elastic body contact portion 23 a of the storage portion 23. It is installed in between. The storage portion 100d has a volume that can store the elastic body contact portion 23a and the elastic body 101.
このようにして構成された座板20及びレバー100は、図3Bに示すように、座板20の下面にレバー100を取り付けることによって、突条21が延びる方向と略直交する方向に摺動可能に設置されることとなり、結果として、レバー100の下面に設けられた係合片100bが、突条21が延びる方向と略直交する方向に摺動可能に設置されることとなる。
具体的には、座板20の下面に設けられた(コの字形状をなす)弾性体当接部23aの少なくとも一部を収納部100dが収納する態様で、収納部23にレバー100を設置し、座板20の下面において、突条21が延びる方向に動きを制限する位置に設置された1対の保持部材23bによって、レバー100を保持することによって、突条21が延びる方向と略直交する方向に、レバー100が摺動可能に設置されることとなり、結果として、レバー100の下面に設けられた係合片100bが、突条21が延びる方向と略直交する方向に摺動可能に設置されることとなる。
なお、レバー100の摺動の変位は、該摺動方向におけるレバー100の収納部100dの長さを調節することによって変化させることができ、この長さに応じた弾性力を有する弾性体101を採用することが好ましい。
As shown in FIG. 3B, the seat plate 20 and the lever 100 configured as described above can slide in a direction substantially orthogonal to the direction in which the protrusions 21 extend by attaching the lever 100 to the lower surface of the seat plate 20. As a result, the engaging piece 100b provided on the lower surface of the lever 100 is slidably installed in a direction substantially orthogonal to the direction in which the protrusion 21 extends.
Specifically, the lever 100 is installed in the storage portion 23 in such a manner that the storage portion 100d stores at least a part of the elastic body abutting portion 23a (formed in a U shape) provided on the lower surface of the seat plate 20. On the lower surface of the seat plate 20, the lever 100 is held by a pair of holding members 23b installed at positions where movement is restricted in the direction in which the ridges 21 extend, so that the direction in which the ridges 21 extend is approximately orthogonal. As a result, the engagement piece 100b provided on the lower surface of the lever 100 is slidable in a direction substantially perpendicular to the direction in which the protrusion 21 extends. Will be installed.
The sliding displacement of the lever 100 can be changed by adjusting the length of the housing portion 100d of the lever 100 in the sliding direction, and the elastic body 101 having an elastic force corresponding to this length can be obtained. It is preferable to adopt.
図4は、本実施形態における座板と、該座板に取り付けられるレバー及び弾性体と、座板取付け部材との設置態様を示す下方向からの斜視図であり、図2A〜図3Bを参照して上述した説明を包括的に示した図である。
図4に示すように、座板取付け部材10は、その側縁部11が座板20の側縁部22に形成された爪部22aの上側に嵌め込まれるとともに、側縁部11と平行に延びる2本の溝部12,12に対して、座板20の下面に側縁部22と平行に延びるようにして形成された2対の突条21,21が当接することで、座板取付け部材10に対し、座板20が前後方向に摺動可能とされる。このとき、座板取付け部材10の上面(溝部12)は、座板20の突条21に当接し、座板取付け部材10の下面(側縁部11)は、座板20の爪部22aに当接しているので、座板取付け部材10の上面及び下面は、座板20に挟持された状態で設置されていることとなる。このように、座板取付け部材10が座板20に挟持されていることによって、座板取付け部材10に対する座板20の前後方向の摺動動作がスムーズに行われる。
また、一方(例えば左側)の側縁部22及び該側縁部22近傍の突条21を分断して、側縁部22と略直交する方向(前後方向に略直交する左右方向)に摺動可能に設置されたレバー100には、その下面に係合片100bが形成されているので、レバー100の摺動によって、座板取付け部材10の側縁部11に形成された切り欠き部11aに対して係合片100bを係合させたり、その係合を解除させたりすることができる。

また、本発明の椅子1に設けられたレバー100は、左右方向への直線的な摺動動作によって、前後方向に摺動可能な座板20を、所定の位置で固定する調節機構をなしているため、上述のように小型化され、動作対象である座板20の下側においてコンパクトに設置することができ、レバー100を使用するとき以外には目立たず、他の調節機構の操作部材と明確に区別できるので、結果として、誤操作を防止することができる。
更に、本発明の椅子1に設けられたレバー100は、椅子の大きさに応じて、長さ方向(レバー100の摺動方向)の寸法や、係合片100bの位置を変更することで、レバー100を片手で操作するのに任意かつ適切な位置に配置することができるので、椅子の大きさにかかわらず高い操作性が維持される。
As described above, in the chair according to the present invention, the mounted sliding mechanism includes the lever 100 in which the engagement piece 100b and the elastic body contact portion 100c (housing portion 100d) are formed, and the lever 100. Since it is sufficient to have the lever holding member 23b for guiding the sliding operation, the notch portion 11a, and the elastic body 101, the number of components is small and the rotation operation is not used, so it is necessary to secure a large installation space. Absent. This is advantageous for downsizing the sliding mechanism.
Further, the engagement state between the engagement piece 100b provided on the lever 100 and the notch 11a is adjusted, and the adjustment of the sliding position of the seat plate 20 with respect to the seat plate mounting member 10 is adjusted by sliding the lever 100. Operability is improved because it is possible only by moving it.
The lever 100 provided in the chair 1 of the present invention has an adjustment mechanism for fixing the seat plate 20 slidable in the front-rear direction at a predetermined position by a linear sliding operation in the left-right direction. Therefore, it is reduced in size as described above, and can be installed compactly under the seat plate 20 that is the object of operation. It is not conspicuous except when the lever 100 is used, and operation members of other adjustment mechanisms Since it can be clearly distinguished, as a result, erroneous operation can be prevented.
Furthermore, the lever 100 provided in the chair 1 of the present invention changes the length direction (sliding direction of the lever 100) and the position of the engagement piece 100b according to the size of the chair, Since the lever 100 can be disposed at an arbitrary and appropriate position to operate the lever 100 with one hand, high operability is maintained regardless of the size of the chair.
本発明の椅子は、操作性が高く、コンパクトな座の摺動機構を備えたので、座の摺動機構を備えた椅子、特に、サイドチェア、ロッキングチェア、リクライニングチェアなど、各種の椅子に好適に用いることができる。 Since the chair of the present invention has high operability and a compact seat sliding mechanism, it is suitable for chairs having a seat sliding mechanism, in particular, various chairs such as a side chair, a rocking chair, and a reclining chair. Can be used.
