Description

本発明は、特に会議室や集会場等で使用される椅子に関する。   The present invention relates to a chair used particularly in a conference room or a meeting place.

この種の椅子は、金属パイプ製の脚に、硬質樹脂製の板材を主体とする背凭れや座を支持させて構成することが多い（例えば、下記特許文献を参照）。
特開２００６−１５８７４５号公報 This type of chair is often configured by supporting a backrest or seat mainly composed of a hard resin plate material on a metal pipe leg (for example, refer to the following patent document).
JP 2006-158745 A

上記例の如き椅子では、背凭れ等が単色になり、ともすれば単調な印象を与えることがあり得る。また、硬質樹脂製の板材は固く変形しにくいものであるため、着座者の身体にかかる体圧を分散させたり、体格や姿形の個人差に対応するべく背凭れ等の表面形状を変化させたりといった作用を期待することはできない。   In the chair as in the above example, the backrest or the like becomes a single color, which may give a monotonous impression. Also, since the hard resin plate is hard and difficult to deform, the body pressure applied to the seated person's body is dispersed, and the surface shape such as the backrest is changed to accommodate individual differences in physique and figure. You can't expect an effect like this.

以上に鑑みてなされた本発明は、簡便な手法で椅子のデザイン製を高めるとともに座り心地を良化することを所期の目的としている。   The present invention made in view of the above is intended to enhance the design of the chair and improve the sitting comfort by a simple method.

上述した課題を解決するべく、本発明では、着座者の身体の荷重を受ける支持部材を弾性変形可能かつ透光性を有する素材を用いて作製し、その支持部材の所定部位の厚みをその他の部位の厚みとは異ならせることによって透光性に変化をつけるようにした。このようなものであれば、剛性を要する部位は肉厚とし、柔軟に変形させたい部位は肉薄として支持部材の部位毎に固さの調整を行いつつ、視覚的な変化を実現することが可能となる。また、支持部材のどの部位が固く、どの部位が柔らかいかを簡単に視認し得ることから、着座者がその椅子の機能を一目で理解できる利点もある。   In order to solve the above-described problems, in the present invention, a support member that receives a load on the body of a seated person is manufactured using a material that is elastically deformable and has translucency, and the thickness of a predetermined portion of the support member is set to other values. The translucency was changed by making it different from the thickness of the part. If it is such, it is possible to realize a visual change while adjusting the hardness for each part of the support member by making the part requiring rigidity thick and the part to be flexibly deformed thin. It becomes. Further, since it is possible to easily visually recognize which part of the support member is hard and which part is soft, there is also an advantage that the seated person can understand the function of the chair at a glance.

剛性を有する支持本体に前記支持部材を取着してこれを支持させるものとし、前記支持部材の所定部位をその近辺よりも肉厚化して当該部位を前記支持本体に接合する構成とすれば、支持部材の支持本体に対する取付強度が向上する。   If the support member is attached to and supported by a rigid support body, and the predetermined part of the support member is thicker than its vicinity and the part is joined to the support body, The attachment strength of the support member to the support body is improved.

前記支持部材の外周縁部を肉厚化し、外周縁部に囲まれた内部を肉薄化しつつ、その内部を着座者の身体側に向けて張り出させるようにすれば、支持部材の外周縁部を支持本体に接合するようにして取付強度を高く保つことができ、同時に、着座者の身体に与える固さ／柔らかさの感触の度合いを適切に調整できる。   If the outer peripheral edge of the support member is thickened and the inside surrounded by the outer peripheral edge is thinned while the inside is projected toward the body side of the seated person, the outer peripheral edge of the support member The attachment strength can be kept high by joining the support body to the support body, and at the same time, the degree of hardness / softness feel given to the body of the seated person can be adjusted appropriately.

前記支持部材は、例えば背凭れの少なくとも一部として適用することが好適である。   The support member is preferably applied as at least a part of the backrest, for example.

本発明によれば、簡便な手法で椅子のデザイン製を高めるとともに座り心地を良化できる。   According to the present invention, it is possible to improve the design of the chair and improve the sitting comfort by a simple method.

以下、本発明の一実施形態を、図面を参照して説明する。図１ないし図４に示す本実施形態の椅子は、例えば金属パイプ材を主体とした脚フレーム４に背座を支持させてなり、特に会議室や集会場等で使用される。   Hereinafter, an embodiment of the present invention will be described with reference to the drawings. The chair of the present embodiment shown in FIGS. 1 to 4 has a back seat supported on a leg frame 4 mainly made of a metal pipe material, for example, and is used particularly in a conference room or a meeting place.

本実施形態の椅子の背凭れは、支持本体たるシェル１と、そのシェル１に取着した支持部材たるランバーサポート体２とを主要な要素とする。   The backrest of the chair according to the present embodiment mainly includes a shell 1 as a support body and a lumbar support body 2 as a support member attached to the shell 1.

シェル１は、例えば硬質樹脂を素材として作製する。図１及び図２に示すように、本実施形態では、背凭れの概形を形作る背シェル１１と、座の概形を形作る座シェル１５とを一体成形し、その座シェル１５に座用クッション３を載置して固定している。図３に示すように、背シェル１１の側断面形状は、上縁から下方に向かうにつれて前方に緩やかに張り出し、着座者の腰部に対応する高さ位置近傍が最も前方に位置し、そこからさらに下方に向かうにつれて若干後退して、最下部で座シェル１５に連続するべく前方に湾曲している。図４に示すように、背シェル１１の平断面形状は、左右両側部が前方、中央部が後方にある凹面状である。総じて、背シェル１１の表面で着座者の背中を包み込むものとなっている。   The shell 1 is made of, for example, a hard resin. As shown in FIGS. 1 and 2, in this embodiment, a back shell 11 that forms a general shape of a backrest and a seat shell 15 that forms a general shape of a seat are integrally formed, and a seat cushion is formed on the seat shell 15. 3 is mounted and fixed. As shown in FIG. 3, the side cross-sectional shape of the back shell 11 gently protrudes forward as it goes downward from the upper edge, and the vicinity of the height position corresponding to the waist of the seated person is located at the forefront, and from there It recedes slightly as it goes downward, and is curved forward to continue to the seat shell 15 at the bottom. As shown in FIG. 4, the flat cross-sectional shape of the back shell 11 is a concave shape in which the left and right sides are forward and the center is rearward. Generally, the back surface of the back shell 11 wraps around the back of the seated person.

しかして、本実施形態では、背シェル１１における着座者の腰部に対応する高さ位置に、表裏を貫通する開口１２を穿ち設けて、この開口１２を閉塞するようにランバーサポート体２を取着している。   Thus, in the present embodiment, the lumbar support body 2 is attached so that the opening 12 penetrating the front and back is provided at the height position corresponding to the waist of the seated person in the back shell 11 and the opening 12 is closed. is doing.

ランバーサポート体２は、弾性変形可能でありかつ透光性を有する材料、例えばウレタンゴム（ウレタン系エラストマ）を素材として作製する。ランバーサポート体２は、正面視シェル１に穿設した開口１２に略対応する外周形状をなすもので、外周縁部２１を比較的肉厚に、外周縁部２１に包囲された内部２２を比較的肉薄に成形している。内部２２は、厚みが外周縁部２１から徐々に薄く変化しつつ、外周縁部２１よりも着座者の身体側即ち前方に張り出しており、後方から見ると凹んでいる。   The lumbar support body 2 is made of a material that is elastically deformable and has translucency, for example, urethane rubber (urethane elastomer). The lumbar support body 2 has an outer peripheral shape substantially corresponding to the opening 12 formed in the shell 1 when viewed from the front. The outer peripheral edge portion 21 is relatively thick and the inner portion 22 surrounded by the outer peripheral edge portion 21 is compared. It is molded thinly. The inner portion 22 is gradually thinner than the outer peripheral edge portion 21 and protrudes toward the body side of the seated person, that is, forward from the outer peripheral edge portion 21, and is recessed when viewed from the rear.

このランバーサポート体２は、肉厚な部位２１即ち固い部位は、素材の色相が濃厚に視認される。他方、肉薄な部位２３即ち柔らかい部位は、肉厚な部位２１と比較して透光性が高いことから、素材の色相のみならずこの部位を透過する環境光の光色が加味されて視認される。故に、明るい室内では、ランバーサポート体２の外周縁部２１は素材の色相が濃く見えて、内部２２は素材の色相が薄く見える、換言すれば明るく（白っぽく）見えることになる。因みに、本実施形態では、ランバーサポート体２の素材の色相と、座用クッション３の色相とを同系色としている。   In the lumbar support body 2, the thick part 21, that is, the hard part, is visually recognized with a thick hue of the material. On the other hand, the thin portion 23, that is, the soft portion, is higher in translucency than the thick portion 21, so that not only the hue of the material but also the light color of the ambient light that passes through this portion is visible. The Therefore, in a bright room, the outer peripheral edge portion 21 of the lumbar support body 2 looks dark in material hue, and the interior 22 looks thin in material hue, in other words, it looks bright (whiter). Incidentally, in this embodiment, the hue of the material of the lumbar support body 2 and the hue of the seat cushion 3 are the same color.

本実施形態では、シェル１における開口１２の内周縁部１３に凹部１４を設け、ランバーサポート体２の外周縁部２１に凸部２２を設けて、これら凹部１４と凸部２２との凹凸嵌合によりシェル１にランバーサポート体２を取着している。より詳しくは、シェル１の開口１２の内周端面に略全周に亘って凹溝１４を形成し、かつランバーサポート体２の外周端面に略全周に亘って凹溝１４に嵌合する凸条２２を形成しており、シェル１の開口１２の内周縁部１３とランバーサポート体２の外周縁部２１とを略全周に亘り接合する。凸条２２の一部分（図示例では、先端部分）は凹溝１４に貫入する方向とは交差する方向（即ち、前方及び／または後方）に突き出して鉤状となっており、凹溝１４の対応部分でこの鉤状を受け入れるようになっている。これは、ランバーサポート体２に荷重が加わったときに凸条２２が凹溝１４から抜出してしまうのを阻止するためである。原則として、ランバーサポート体２はシェル１に一体成形する。但し、ランバーサポート体２をシェル１に対して着脱可能としても構わない。   In the present embodiment, a concave portion 14 is provided in the inner peripheral edge portion 13 of the opening 12 in the shell 1, and a convex portion 22 is provided in the outer peripheral edge portion 21 of the lumbar support body 2. As a result, the lumbar support body 2 is attached to the shell 1. More specifically, a concave groove 14 is formed on the inner peripheral end surface of the opening 12 of the shell 1 over substantially the entire circumference, and the convex fitting fits into the concave groove 14 over the entire outer peripheral end surface of the lumbar support body 2. A strip 22 is formed, and the inner peripheral edge 13 of the opening 12 of the shell 1 and the outer peripheral edge 21 of the lumbar support body 2 are joined over substantially the entire circumference. A portion of the ridge 22 (in the illustrated example, the tip portion) protrudes in a direction (that is, forward and / or rearward) intersecting the direction penetrating the concave groove 14 and has a hook shape. The part is designed to accept this plight. This is to prevent the ridge 22 from being pulled out of the groove 14 when a load is applied to the lumbar support body 2. In principle, the lumbar support body 2 is formed integrally with the shell 1. However, the lumbar support body 2 may be detachable from the shell 1.

背シェル１１にランバーサポート体２を取着した状態で、ランバーサポート体２は背シェル１１の表面よりも突出している。また、シェル１の開口１２の内周縁部１３を後方に膨出させることで、この内周縁部１３の厚みをランバーサポート体２の外周縁部２１の厚みに略等しくしており、シェル１とランバーサポート体２との境界部分に表裏ともに目立つ段差や隙間は生じない。   In a state where the lumbar support body 2 is attached to the back shell 11, the lumbar support body 2 protrudes from the surface of the back shell 11. Further, the inner peripheral edge 13 of the opening 12 of the shell 1 is bulged rearward so that the thickness of the inner peripheral edge 13 is substantially equal to the thickness of the outer peripheral edge 21 of the lumbar support body 2. There are no conspicuous steps or gaps at the boundary with the lumbar support body 2 on both sides.

本実施形態によれば、着座者の身体の荷重を受ける支持部材２を弾性変形可能かつ透光性を有する素材を用いて作製し、その支持部材２の所定部位２１の厚みをその他の部位２３の厚みとは異ならせることによって透光性に変化をつけるようにしたため、剛性を要する部位は肉厚とし、柔軟に変形させたい部位は肉薄として支持部材２の部位毎に固さの調整を行いつつ、視覚的な変化を実現することが可能となる。また、支持部材２のどの部位が固く、どの部位が柔らかいかを簡単に視認し得ることから、着座者がその椅子の機能を一目で理解できる利点もある。   According to the present embodiment, the support member 2 that receives the load of the body of the seated person is manufactured using a material that is elastically deformable and has translucency, and the thickness of the predetermined portion 21 of the support member 2 is set to the other portion 23. Since the translucency is changed by changing the thickness of the support member 2, the portion requiring rigidity is made thick, and the portion to be flexibly deformed is made thin, and the rigidity of each support member 2 is adjusted. However, visual changes can be realized. Further, since it is possible to easily visually recognize which part of the support member 2 is hard and which part is soft, there is also an advantage that the seated person can understand the function of the chair at a glance.

剛性を有する支持本体１１に前記支持部材２を取着してこれを支持させるものとし、前記支持部材２の所定部位２１をその近辺よりも肉厚化して当該部位２１を前記支持本体１１に接合する構成としたため、支持部材２の支持本体１１に対する取付強度が向上する。   The support member 2 is attached to and supported by a rigid support body 11, and the predetermined portion 21 of the support member 2 is made thicker than the vicinity thereof and the portion 21 is joined to the support body 11. Since it is set as the structure which carries out, the attachment strength with respect to the support main body 11 of the support member 2 improves.

前記支持部材２の外周縁部２１を肉厚化し、外周縁部２１に囲まれた内部２２を肉薄化しつつ、その内部２２を着座者の身体側に向けて張り出させるようにしているため、支持部材２の外周縁部２１を支持本体１１に接合するようにして取付強度を高く保つことができ、同時に、着座者の身体に与える固さ／柔らかさの感触の度合いを適切に調整できる。   Since the outer peripheral edge 21 of the support member 2 is thickened and the inner 22 surrounded by the outer peripheral edge 21 is thinned, the inner 22 is projected toward the body side of the seated person. By attaching the outer peripheral edge portion 21 of the support member 2 to the support body 11, the attachment strength can be kept high, and at the same time, the degree of hardness / softness feel given to the body of the seated person can be adjusted appropriately.

なお、本発明は以上に詳述した実施形態に限られるものではない。例えば、支持本体の開口の内周縁部に凸部または凸条を設け、支持部材の外周縁部に凹部または凹溝を設けて、両者の凹凸嵌合構造を構築するようにしてもよい。また、支持本体に支持部材を取着する方法は、上述した凹凸嵌合には限定されず、既知の様々な取着・固定方法を採用することが許される。加えて、支持部材を支持本体に対して着脱不能とする態様を妨げない。   The present invention is not limited to the embodiment described in detail above. For example, a convex or convex line may be provided on the inner peripheral edge of the opening of the support body, and a concave or convex groove may be provided on the outer peripheral edge of the support member to construct a concave / convex fitting structure between them. Further, the method of attaching the support member to the support body is not limited to the above-described uneven fitting, and it is allowed to adopt various known attachment / fixing methods. In addition, the aspect which makes a support member non-detachable with respect to a support main body is not prevented.

上記実施形態では、支持本体の開口の周縁が閉じていたが、開口の周縁は完全に閉じていなくともよい。並びに、支持本体の開口の内周縁全体と、支持部材の外周縁全体とを接合しなくともよい。支持部材が、支持本体の開口の全体を閉塞するとは限られない。   In the above embodiment, the peripheral edge of the opening of the support body is closed, but the peripheral edge of the opening may not be completely closed. In addition, it is not necessary to join the entire inner peripheral edge of the opening of the support body and the entire outer peripheral edge of the support member. The support member does not necessarily block the entire opening of the support body.

支持部材の形状も、上記実施形態の態様には限定されない。図５及び図６に例示するように、支持本体１１に接合する部位即ち外周縁部２１以外の部位２４を肉厚化することも考えられる。図示例では、外周縁部２１に包囲された内部２３に肉厚な部位２４を形成している。この部位２４は、他の部位２１、２３よりもさらに前方に突き出した凸形状をなしており、着座者が背を大きく凭せかけたときに着座者の身体をマッサージする、いわばマッサージボールとなる。   The shape of the support member is not limited to the above embodiment. As illustrated in FIG. 5 and FIG. 6, it is conceivable to thicken a portion to be joined to the support body 11, that is, a portion 24 other than the outer peripheral edge portion 21. In the illustrated example, a thick portion 24 is formed in an interior 23 surrounded by the outer peripheral edge 21. This part 24 has a convex shape that protrudes further forward than the other parts 21 and 23, and becomes a so-called massage ball that massages the body of the seated person when the seated person leans back greatly. .

図５及び図６に示す例とは逆に、図８に示すように、肉厚な部位２５が後方に突き出した凸形状となっていることもあり得る。このときにも、図７に示すように、支持部材２の表面がなだらかな面であっても裏面側には厚薄の変化がつけてあることが視認できる。即ち、支持部材２における固い部位２１、２５、柔らかい部位２３の分布やその固さ／柔らかさの程度が表面側から見てとれる。これは、支持部材を椅子の座面等に適用する場合にも有効となる。   Contrary to the examples shown in FIGS. 5 and 6, as shown in FIG. 8, the thick portion 25 may have a convex shape protruding backward. Also at this time, as shown in FIG. 7, even if the surface of the support member 2 is a gentle surface, it can be visually recognized that a change in thickness is applied to the back surface side. That is, the distribution of the hard portions 21 and 25 and the soft portion 23 in the support member 2 and the degree of hardness / softness can be seen from the surface side. This is also effective when the support member is applied to a chair seat or the like.

支持部材の機能は、ランバーサポートには限られない。図９に例示するように、支持本体１１に着座者の背筋に対して略平行に上下に延伸する開口１６を設け、その開口に支持部材５を取着してもよい。この支持部材５は、着座者の背筋または肩胛骨付近を押圧する機能を実現するものとなる。図示例のように、支持本体１１に複数の開口１６を設け、複数の支持部材５を取着することを妨げない。開口１６、支持部材５は、上記実施形態における開口１２、支持部材２と同様のものとすることができる。   The function of the support member is not limited to the lumbar support. As illustrated in FIG. 9, the support body 11 may be provided with an opening 16 extending up and down substantially parallel to the back muscles of the seated person, and the support member 5 may be attached to the opening 16. This support member 5 realizes a function of pressing near the back muscles of the seated person or the shoulder ribs. As in the illustrated example, the support body 11 is provided with a plurality of openings 16 so as not to prevent the plurality of support members 5 from being attached. The opening 16 and the support member 5 can be the same as the opening 12 and the support member 2 in the above embodiment.

上記実施形態では、支持本体に開口を設け、その開口に支持部材を取着するようにしていたが、支持本体に開口を設けずに支持部材を取着しても構わない。   In the above embodiment, an opening is provided in the support body, and the support member is attached to the opening. However, the support member may be attached without providing the opening in the support body.

上記実施形態では、弾性変形可能な支持部材を剛性を有する支持本体に取着して椅子の背凭れを構成していたが、肉厚部位の形状及び厚みを適当に設計することで支持部材単独で椅子の背凭れを構成する態様もとり得る。   In the above embodiment, the backrest of the chair is configured by attaching the elastically deformable support member to the rigid support body, but the support member alone can be obtained by appropriately designing the shape and thickness of the thick part. It is also possible to adopt a mode that constitutes the backrest of the chair.

本発明の適用対象は、椅子の背凭れには限定されない。座シェルを支持本体とし、これに支持部材を取着して椅子の座を構成することも考えられる。このときの支持部材は、例えば着座者のペルビックサポート機能を実現し得る。同様に、椅子の肘掛けやヘッドレスト等に本発明を適用することも可能である。   The application target of the present invention is not limited to the backrest of a chair. It is conceivable that the seat shell is used as a support body, and a support member is attached to the seat shell to constitute a chair seat. The support member at this time can realize a perbic support function of a seated person, for example. Similarly, the present invention can be applied to an armrest or a headrest of a chair.

その他各部の具体的構成は上記実施形態に限られるものではなく、本発明の趣旨を逸脱しない範囲で種々変形が可能である。   Other specific configurations of the respective parts are not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.
