Description
本発明は、椅子の肘当ての高さを調節しうるようにした肘掛け装置に関する。 The present invention relates to an armrest device capable of adjusting the height of an armrest of a chair.
椅子の肘当ての高さを、着座者の体格による腕の位置の違い、あるいはコンピュータ等のOA機器のキーボードなどを操作する際における腕の支持位置を変更するために調節しうるようにした肘掛け装置は、公知である(例えば特許文献1、2参照)。
上記特許文献に記載されている従来の肘掛け装置は、いずれも、肘掛け支柱内に設けた高さ調節機構における上下複数の係止部に軸を係脱させて、肘当ての高さを段階的に調節するのに、肘掛け支柱の外部に突出した操作レバーをその都度回動操作しなければならないため、肘当ての高さ調整が面倒である。 All of the conventional armrest devices described in the above-mentioned patent documents step up and down the height of the armrest by disengaging the shafts from the upper and lower locking portions of the height adjustment mechanism provided in the armrest strut. In order to adjust the height of the armrest, it is necessary to rotate the operating lever protruding outside the armrest support column each time.
また、操作レバーが肘掛け支柱の外部に突出しているため、その部分において肘掛け支柱が膨らみ、見栄えも悪い。 Moreover, since the operation lever protrudes outside the armrest strut, the armrest strut swells at that portion, and the appearance is poor.
本発明は、上記問題点に鑑みてなされたもので、操作レバー等を操作したりすることなく、肘当ての高さを簡単に調節しうるようにした、見栄えのよい椅子の肘掛け装置を提供することを目的としている。 The present invention has been made in view of the above problems, and provides a good-looking chair armrest device that can easily adjust the height of an armrest without operating an operation lever or the like. The purpose is to do.
本発明によると、上記課題は、次のようにして解決される。
(1)上方を向く筒状の肘掛け支柱の上端部内に、内面に斜め上方に開口する上下複数段の係止溝を有するとともに、該係止溝を挟む両側の互いに対向する内面に、互いに平行をなして上下方向を向く2条の縦溝と、前記上下両端の係止溝とほぼ等高をなす位置において斜め上方を向き、前記2条の縦溝の上下両端と連続する傾斜溝とからなる無端状の1対のガイド溝を有する筒状の高さ調節部材を嵌着し、該高さ調節部材内に、上端に肘当てが取付られた肘当て支持杆を上下に摺動可能に嵌合し、該肘当て支持杆の下端部に、上下方向を向く基片と、その上端よりほぼ倒立V字状をなすように垂下し、下端部に前記係止溝と係脱可能な係止爪を有する弾性変形可能な停止片とからなる停止部材の上端を、回動自在に枢着するとともに、前記基片の下端に突設したガイド軸の両端部を、前記1対のガイド溝に、ガイド軸が前記ガイド溝における2条の縦溝のうち、前記係止溝に近い側の一方の縦溝内に位置しているとき、前記係止爪が係止溝に係合し、かつガイド軸が前記上部の傾斜溝に沿って他方の縦溝内に位置したとき、係止爪が係止溝より離間し、さらに、ガイド軸が前記下部の傾斜溝に沿って前記一方の縦溝の下端に移動したとき、係止爪が最下段の係止溝と再係合するように、摺動自在に嵌合する。
According to the present invention, the above problem is solved as follows.
(1) The upper end of the cylindrical armrest strut facing upward has a plurality of upper and lower engaging grooves opened obliquely upward on the inner surface, and is parallel to the mutually opposing inner surfaces on both sides of the engaging groove. And two vertical grooves facing in the vertical direction, and an inclined groove which faces obliquely upward at a position substantially equal to the locking grooves at both upper and lower ends and is continuous with the upper and lower ends of the two vertical grooves. A cylindrical height adjusting member having a pair of endless guide grooves is fitted, and an elbow rest supporting rod with an elbow rest attached to the upper end can be slid up and down in the height adjusting member. A base piece that faces up and down at the lower end of the elbow pad support rod and hangs so as to form a substantially inverted V shape from the upper end thereof, and the engagement groove that can be engaged with and disengaged from the locking groove at the lower end The upper end of a stop member composed of an elastically deformable stop piece having a pawl is pivotally attached to the upper end of the stop member. The two ends of the guide shaft projecting from the lower end of the piece are in the pair of guide grooves, and one of the two vertical grooves in the guide groove in the vertical groove on the side closer to the locking groove. When the locking claw is engaged with the locking groove and the guide shaft is positioned in the other vertical groove along the upper inclined groove, the locking claw is more than the locking groove. Further, when the guide shaft moves to the lower end of the one vertical groove along the lower inclined groove, the locking claw is slidable so as to re-engage with the lowermost locking groove. Mating.
(2)上記(1)項において、肘掛け支柱が前傾して起立するものにおいて、係止溝を、高さ調節部材の前部の内面に、かつ1対のガイド溝を左右の内面に、それぞれ設ける。 (2) In the above item (1), in the armrest strut standing upright, the locking groove is formed on the inner surface of the front portion of the height adjusting member, and the pair of guide grooves are formed on the left and right inner surfaces. Provide each.
(3)上記(1)または(2)項において、肘当て支持杆を角筒状断面として、内部に、停止部材を、その係止爪を肘当て支持杆に形成した開口より突出させて回動自在に収容するとともに、基片に突設したガイド軸を、肘当て支持杆の両側板に穿設した長孔に挿通して、1対のガイド溝に嵌合させる。 (3) In the above item (1) or (2), the elbow rest support rod is formed into a rectangular tube cross section, and the stop member is protruded from the opening formed in the elbow support support rod. The guide shaft protruding from the base piece is inserted into the long holes formed in the both side plates of the elbow pad support rod and fitted into the pair of guide grooves.
(4)上記(1)〜(3)項のいずれかにおいて、高さ調節部材と停止部材とを合成樹脂により形成する。 (4) In any one of the above items (1) to (3), the height adjusting member and the stop member are formed of a synthetic resin.
請求項1記載の発明によれば、肘当て支持杆を上昇させると、それに枢支された停止部材における基片の下端部のガイド軸が、ガイド溝における係止溝に近い側の一方の縦溝に沿って上方に移動することにより、停止部材の係止爪は、停止片を弾性変形させながら下段の係止溝より離脱し、順次上段の係止溝と弾性係合するため、肘当ての高さを、係止溝の数だけ段階的に調節することができる。 According to the first aspect of the present invention, when the elbow pad support rod is raised, the guide shaft at the lower end portion of the base piece of the stop member pivotally supported by the elbow rest support rod is on one side of the guide groove on the side near the locking groove. By moving upward along the groove, the locking claw of the stop member is detached from the lower locking groove while elastically deforming the stop piece, and then elastically engages with the upper locking groove, so that the elbow rest Can be adjusted stepwise by the number of the locking grooves.
また、ガイド軸が上部の傾斜溝に沿って、他方の縦溝内に移動すると、停止部材の係止爪が係止溝より離間するので、肘当て支持杆を下限位置まで一度に下降させることができ、かつガイド軸が下部の傾斜溝に沿って再度一方の縦溝の下端に移動させられることにより、係止爪は最下段の係止溝と自動的に再係合する。 Also, when the guide shaft moves along the upper inclined groove into the other vertical groove, the locking claw of the stop member is separated from the locking groove, so that the elbow pad support rod is lowered at a time to the lower limit position. When the guide shaft is moved again to the lower end of one of the vertical grooves along the lower inclined groove, the locking claw is automatically re-engaged with the lowermost locking groove.
従って、従来のように、肘掛け支柱に操作レバーを設け、それを操作して肘当ての高さを調節する必要はなく、肘当ての高さ調節が容易となるとともに、操作レバー等が外部に露出しないので、見栄えもよくなる。 Therefore, it is not necessary to adjust the height of the elbow rest by operating the arm lever on the armrest strut as in the prior art, and it is easy to adjust the height of the elbow rest. Since it is not exposed, it looks better.
請求項2記載の発明によれば、肘当てに加わる垂直荷重が、高さ調節部材の前部内面に設けた係止溝により効果的に受支されるとともに、停止部材も、左右1対のガイド溝に沿って円滑に上下動することができる。 According to the second aspect of the present invention, the vertical load applied to the elbow rest is effectively received by the locking groove provided on the inner surface of the front portion of the height adjusting member, and the stop member is also a pair of left and right. It can move up and down smoothly along the guide groove.
請求項3記載の発明によれば、停止部材を、肘当て支持杆の中心部に配設しうるので、肘当てに加わる荷重をバランスよく受けることができるとともに、停止部材が高さ調節部材の内面と接触するのが防止される。 According to the third aspect of the present invention, since the stop member can be disposed at the center of the elbow rest support rod, the load applied to the elbow rest can be received in a well-balanced manner, and the stop member can be the height adjusting member. Contact with the inner surface is prevented.
また、停止部材の両側面を、肘当て支持杆の内面に近接または摺接させることにより、停止部材に曲げ荷重が作用しても、それがぐら付いたり、枢軸が変形したりする恐れはない。 Moreover, even if a bending load is applied to the stop member by bringing both side surfaces of the stop member into close contact or sliding contact with the inner surface of the elbow support rod, there is no risk of wobbling or deformation of the pivot axis. .
請求項4記載の発明によれば、停止部材の係止爪が高さ調節部材の係止溝と係合する際の衝撃音が小さくなる。 According to the fourth aspect of the present invention, the impact sound when the locking claw of the stop member engages with the locking groove of the height adjusting member is reduced.
以下、本発明の最良と思われる実施形態を、図面に基づいて説明する。

図10の(a)〜(d)は、肘当て(4)の高さを調節する際の高さ調節機構(10)の作用を示している。 (A)-(d) of FIG. 10 has shown the effect | action of the height adjustment mechanism (10) at the time of adjusting the height of an elbow rest (4).
肘当て(4)が下限に位置している状態(図1の状態)では、図10(a)に示すように、ガイドピン(23)が、高さ調節部材(12)のガイド溝(15)における前部の縦溝(15a)の下端と当接することにより、停止部材(13)の係止爪(13c)は、最下段の係止溝(14)に進入して係止されている。 In the state where the elbow rest (4) is located at the lower limit (the state shown in FIG. 1), as shown in FIG. 10 (a), the guide pin (23) is inserted into the guide groove (15) of the height adjusting member (12). ), The locking claw (13c) of the stop member (13) enters the bottom locking groove (14) and is locked. .
この状態から肘当て(4)を引き上げると、図10(b)に示すように、ガイドピン(23)が前部の縦溝(15a)に沿って上昇することにより、係止爪(13c)は、停止部材(13)の停止片(13b)を後方に弾性変形させながら上方に移動し、最下段の係止溝(14)より離脱する。 When the elbow rest (4) is pulled up from this state, as shown in FIG. 10 (b), the guide pin (23) rises along the longitudinal groove (15a) at the front portion, so that the locking claw (13c) Moves upward while elastically deforming the stop piece (13b) of the stop member (13) rearwardly, and disengages from the lowermost locking groove (14).
この状態から肘当て(4)をさらに、引き上げると、係止爪(13c)は、弾性変形させられていた停止片(13b)の弾性復元力により、第2段目の係止溝(14)に自動的に突入して弾性係合され、肘当て(4)はその位置で停止保持される。 When the elbow rest (4) is further pulled up from this state, the locking claw (13c) is moved to the second locking groove (14) by the elastic restoring force of the stop piece (13b) that has been elastically deformed. The elbow rest (4) is stopped and held at that position.
この位置から、さらに肘当て(4)を引き上げると、上記動作を繰り返すことにより、順次上段の係止溝(14)に係止爪(13b)が弾性係合し、肘当て(4)の高さを段階的に調節することができる。 When the elbow rest (4) is further lifted from this position, by repeating the above operation, the retaining claws (13b) are successively elastically engaged with the upper retaining grooves (14), and the height of the elbow rest (4) is increased. The height can be adjusted in stages.
肘当て(4)を上限位置まで引き上げると、図10(c)に示すように、ガイドピン(23)が、ガイド溝(15)における上部の斜め後ろ上方を向く傾斜溝(15c)に沿って、後部の縦溝(15b)の上端に移動することにより、停止部材(13)全体が上端の枢支ピン(20)を中心として後ろ上方に回動させられ、係止爪(13b)は、最上段の係止溝(14)より離脱する。 When the elbow rest (4) is pulled up to the upper limit position, as shown in FIG. 10 (c), the guide pin (23) moves along the inclined groove (15c) that faces the upper rear of the guide groove (15). Then, by moving to the upper end of the rear vertical groove (15b), the entire stop member (13) is rotated rearward and upward about the pivot pin (20) at the upper end, and the locking claw (13b) Detach from the uppermost locking groove (14).
この状態で肘当て(4)を下降させると、図10(d)に示すように、ガイドピン(23)が後部の縦溝(15b)に沿って下方に移動することにより、停止部材(13)及び肘当て(4)は下限位置まで一度に下降するとともに、ガイドピン(23)が、下部の傾斜溝(15d)に沿って、前部の縦溝(15a)の下端まで斜め前下方に移動させられることにより、停止部材(13)全体が枢支ピン(20)を中心として前方に回動し、係止爪(13c)は最下段の係止溝(14)に自動的に再係合し、図10(a)の状態に復帰する。 When the elbow rest (4) is lowered in this state, as shown in FIG. 10 (d), the guide pin (23) is moved downward along the longitudinal groove (15b) at the rear, so that the stop member (13 ) And the elbow rest (4) are lowered to the lower limit at a time, and the guide pin (23) is diagonally forward and downward along the lower inclined groove (15d) to the lower end of the front vertical groove (15a). By being moved, the entire stop member (13) pivots forward about the pivot pin (20), and the locking claw (13c) is automatically re-engaged with the lowermost locking groove (14). In this case, the state returns to the state shown in FIG.
このように、単に肘当て(4)自体を昇降させるだけの簡単な操作で、その高さを段階的に調節することができる。
なお、上記肘当て(4)を下向させる際、自重により急速に下降するのを防止し、下限位置で停止したときの衝撃を緩和するために、ガイド溝(15)における後部の縦溝(15b)の幅を、ガイドピン(23)が適度の摩擦力をもって摺動しうる寸法としたり、縦溝(15b)の内面にゴム等の摩擦シートを貼着するなどしてもよい。
In this way, the height can be adjusted stepwise by a simple operation of simply raising and lowering the elbow rest (4) itself.
When the elbow rest (4) is lowered, the rear vertical groove (15) in the guide groove (15) is used to prevent rapid lowering due to its own weight and to mitigate the impact when stopped at the lower limit position. The width of 15b) may be set such that the guide pin (23) can slide with an appropriate frictional force, or a friction sheet such as rubber may be attached to the inner surface of the longitudinal groove (15b).
上記実施形態では、肘当て支持杆(3)の上端に基板(7)を固着し、その上面に肘当て支持板(50)を設けているが、基板(7)を省略し、肘当て支持板(50)を直接肘当て支持杆(3)の上端に固着してもよい。 In the above embodiment, the base plate (7) is fixed to the upper end of the elbow pad support rod (3) and the elbow pad support plate (50) is provided on the upper surface thereof, but the base plate (7) is omitted and the elbow pad support plate is supported. The plate (50) may be directly fixed to the upper end of the elbow rest support rod (3).
パッド部材(26)は、芯材(40)と表装材(41)とを一体成形して構成されているが、それらを別々に成形して、接着剤等により貼着して形成してもよい。この際、芯材(40)の小孔(39)は、その開口面を表装材(41)により単に覆うのみとしてもよい。 The pad member (26) is configured by integrally molding the core material (40) and the cover material (41), but may be formed by separately molding them and bonding them with an adhesive or the like. Good. At this time, the small hole (39) of the core member (40) may simply cover the opening surface with the cover material (41).
上記実施形態では、上下複数段の係止溝(14)を、2分割とした一方(右方)の半筒状片(12a)の前部内面に設けたが、それを、他方(左方)の半筒状片(12b)の後部内面に設けてもよい。この際には、停止部材(13)の向きを前後反対とすればよい。 In the above embodiment, the upper and lower multi-stage locking grooves (14) are provided on the inner surface of the front part of one (right side) semi-cylindrical piece (12a) divided into two parts. ) Of the semi-cylindrical piece (12b).
