Abstract

PROBLEM TO BE SOLVED: To enable a surface sheet, such as cloth, to be stretched without causing wrinkles more than permitted at the edge of the surface sheet going around the back of an inner shell, in order to create images that provide softness and warmth on the appearance of the back of a backrest plate, by exposing a portion of the inner shell wrapped by the surface sheet, even at the back of the backrest plate. SOLUTION: This edge processing structure is designed so that an inner shell 1 having a cushion material mounted on its front is covered at its back with an outer shell except at a portion of a projection 6 going along its periphery, and so that the edge 7 of a surface sheet 5 stretched to wrap the cushion material and the periphery of the inner shell 1 is sandwiched between the inner shell 1 and the outer shell. In this case, a slit 8 is formed in a position on the side of the projection where the wrinkles of the surface sheet 5 stretched to wrap the projection 6 of the inner shell concentrate, and a portion of the surface sheet is pushed into the slit to prevent wrinkling.

Description

【０００１】
【発明の属する技術分野】
本発明は、椅子のクッション体における表皮シートの端縁処理構造に係わり、更に詳しくは背凭れ板や座板のクッション体の表皮シートを皺が寄ることなく張ることが可能な表皮シートの端縁処理構造に関する。
【０００２】
【従来の技術】
従来、表面側にクッション体を装着したインナーシェルを、それを外覆するアウターシェルに重合状態で嵌着してなる椅子の背凭れ板や座板の構造は各種提供されている。そして、前記クッション体は、インナーシェルの表面側に配設するクッション材とその表面を覆う表皮シートで構成されており、表皮シートはクッション材とインナーシェルの周縁部を包み込むように張られ、インナーシェルの裏面側にアウターシェルを装着することによって、表皮シートの端縁をインナーシェルとアウターシェルで挾持する構造が一般的である。
【０００３】
ここで、インナーシェルの裏面側に回り込んだ表皮シートの端縁には、皺が生じるので、従来はこの皺が隠れるようにアウターシェルでインナーシェルの全体を外覆していた。
【０００４】
ところが、インナーシェルの全体をアウターシェルで外嵌する構造では、例えば背凭れ板にあっては、その背面側はアウターシェルのみとなって、着座者以外の者が最も目につく椅子の背凭れ板背面が硬く、冷たい外観を呈することになる。そこで、背凭れ板の背面の外観性において柔らかさ、温かさといったイメージを創出するために、背面側にもクロス等の表皮シートで包み込まれたインナーシェルの一部を露出させることが考慮されるが、インナーシェルの裏面側に巻き込んだ表皮シートの皺も露出することは避けられない。
【０００５】
このような構造において、インナーシェル裏面側に回り込んだ表皮シートに皺を発生させないようにするためには、表皮シートを縫製してクッション材とインナーシェルの外形に合った袋状する方法、あるいは別の部材に表皮シートを張って、それを裏面側に嵌め込む方法が考えられるが、前者はミシン工程が必要であり且つマチやミシン跡が生じ、また後者は別部材が必要であり且つその部材にシートを張る工程も必要となってコスト高となる。
【０００６】
【発明が解決しようとする課題】
そこで、本発明が前述の状況に鑑み、解決しようとするところは、背凭れ板の背面側にもクロス等の表皮シートで包み込まれたインナーシェルの一部を露出させて、背面の外観性において柔らかさ、温かさといったイメージを創出すべく、インナーシェル裏面側に回り込んだ表皮シートの端縁に、許容以上の皺を発生させずに張ることが可能な椅子のクッション体における表皮シートの端縁処理構造を提供する点にある。
【０００７】
【課題を解決するための手段】
本発明は、前述の課題解決のために、表面側にクッション材を装着したインナーシェルの裏面側を、その周縁に沿った一部の突出部を除きアウターシェルで外覆するとともに、クッション材とインナーシェルの周縁を包み込むように張った表皮シートの端縁をインナーシェルとアウターシェルとで挾持してなる椅子のクッション体における表皮シートの端縁処理構造であって、前記インナーシェルの突出部を包み込むように張った前記表皮シートの皺が集中する突出部側位に、中間部分に内外に弾力性を備えたスリット孔を形成し、該表皮シートの一部をスリット孔の中間部分を内方へ弾性変形させながら該スリット孔内に押し込んで皺の発生を防止してなる椅子のクッション体における表皮シートの端縁処理構造を構成した。
【０００８】
ここで、前記クッション体が背凭れ板を構成するものであり、前記突出部の両側に近接して取付けた背凭れ支持杆によって、スリット孔に押し込んだ表皮シートの部位を隠蔽してなることが特に好ましい。
【０００９】
更に、前記スリット孔が側面視略Ｈ字状に開設されたものであると、インナーシェルの突出部に張った表皮シートの端縁の皺を、許容される必要最小限に止めることが可能である。
【００１０】
【発明の実施の形態】
次に添付図面に示した本発明の実施形態に基づき更に詳細に説明する。本実施形態では、椅子の背凭れ板における構造を例示するが、座板においても基本的な技術的思想は同一である。しかし、座板においてはその裏面側に表皮シートで包み込んだ部分を露出させる必要性は少ない。
【００１１】
図１は本発明に係る椅子の全体斜視図、図２は背凭れ板の構造を示し、図３〜図５は本発明の要部を説明するための図面であり、図中１はインナーシェル、２はクッション体、３はアウターシェル、４はクッション材、５は表皮シートをそれぞれ示している。
【００１２】
本発明に係る椅子は、図１に示すように、脚部Ａで支持した座板Ｂに、その後部両側から上方へ立ち上がった蛇腹で外被された背凭れ支持杆Ｃ１，Ｃ１を介して背凭れ板Ｃを取付けたものであり、座板Ｂは前後スライド移動可能、また背凭れ板Ｃは前後傾動可能な構造を有している。そして、本発明は前記座板Ｂ及び背凭れ板Ｃを構成するクッション体２の表皮シート５の端縁処理構造に関するものである。
【００１３】
本発明は、表面側にクッション材４を装着したインナーシェル１の裏面側を、その周縁に沿った一部の突出部６を除きアウターシェル３で外覆するとともに、クッション材４とインナーシェル１の周縁を包み込むように張った表皮シート５の端縁７をインナーシェル１とアウターシェル３とで挾持してなる椅子のクッション体２における表皮シート５の端縁処理構造であって、前記インナーシェル１の突出部６を包み込むように張った前記表皮シート５の皺が集中する突出部６側位にスリット孔８を形成し、該表皮シート５の一部をスリット孔８内に押し込んで皺の発生を防止してなることを要旨としている。
【００１４】
ここで、前記インナーシェル１とアウターシェル３は、共に合成樹脂で一体成形されたものであり、図示しないが前記インナーシェル１に複数の開口を形成し、前記アウターシェル３には、前記開口に対応する位置に複数の係合爪を突設し、インナーシェル１とアウターシェル３を重合状態で開口と係合爪が抜止め嵌合する構造である。
【００１５】
そして、前記インナーシェル１の表面側には、発泡ウレタン製のクッション材４を接着し、それをクロスやレザー等の表皮シート５で外覆して形成したクッション体２と一体となしている。ここで、インナーシェル１をクッション材４の成形金型内に配置しておくと、クッション材４の発泡成形時にインナーシェル１の表面側に自動的に接着され、クッション材４の一部はインナーシェル１に形成した貫通孔を通してその裏面側に回り込み、アンカー効果によってより強固にインナーシェル１とクッション材４が一体化する。
【００１６】
前記背凭れ支持杆Ｃ１の上端は、背凭れ板Ｃを前後傾動可能に支持する弾性関節機構及び背凭れ板Ｃを上下にスライド移動させる背スライド機構を介してアウターシェル３の装着部９に連結されている。そして、前記アウターシェル３の装着部９は、前記インナーシェル１の両側に設けた湾曲部１０，１０で覆われている。また、前記インナーシェル１の下縁部に沿って一体形成した突出部６は、両湾曲部１０，１０の間に設けられ、下方と裏面側へ突出したものであり、その両端面１１，１１には、側面視略Ｈ字状にスリット孔８がそれぞれ開設されている。ここで、前記スリット孔８は、前記端面１１の上下縁に沿った部分８Ａ，８Ｂと、その中央部間を連通した部分８Ｃとよりなっている。
【００１７】
そして、前記インナーシェル１の表面側にクッション材４を配設した状態で、該クッション材４とインナーシェル１の周縁を包み込むように前記表皮シート５が張られている。特に、前記突出部６の端面１１においては、突出部６の表面側の下方からと側方から、更には突出部６の上面側から下方へ回り込んだ表皮シート５の端縁７が集合し、この端縁７の余分な部分を前記スリット孔８内に押し込むのである（図５参照）。特に、前記突出部６の端面１１であって、表面側と下面側のコーナー部に近い部分の端縁７の集合が多くなるので、この部分に対応するスリット孔８の下縁部分８Ｂの開口幅を広く設定している。また、スリット孔８の中間部分８Ｃの両側の端面１１部分は、両端が上下縁部分８Ａ，８Ｂとで切断されていることから、内外に弾力性を備えており、表皮シート５の端縁７１を押し込む際に内方へ弾性変形して中間部分８Ｃの開口幅が広くなり、端縁７の押し込み作業が簡単になる。
【００１８】
それから、前記クッション体２と一体となった状態のインナーシェル１とアウターシェル３とを前述の如く重合状態で嵌着することによって、前記表皮シート５の全周の端縁７は、インナーシェル１とアウターシェル３とで挾持されるのである。ここで、前記クッション材４の発泡成形時に、前述の如くインナーシェル１と一体化するとともに、クッション材４と表皮シート５とを一体化することも好ましく、更にインナーシェル１の周縁の裏面側へ回り込んだ表皮シート５の端縁７をインナーシェル１の裏面側に接着剤で接着することも好ましい。
【００１９】
そして、前記インナーシェル１の突出部６の端面１１には、前記背凭れ支持杆Ｃ１が近接して取付けられるので、前記スリット孔８に押し込んだ表皮シート５の端縁７の近傍を含めて、前記端面１１に位置する表皮シート５が略隠蔽されるので、外観性に全く問題がないのである。
【００２０】
【発明の効果】
以上にしてなる本発明の椅子のクッション体における表皮シートの端縁処理構造によれば、以下に示す顕著な効果を奏するものである。
【００２１】
請求項１によれば、インナーシェル裏面側に回り込んだ表皮シートの端縁に、許容以上の皺を発生させずに張ることができるので、例えば背凭れ板の背面側にもクロス等の表皮シートで包み込まれたインナーシェルの一部を露出させて、背面の外観性において柔らかさ、温かさといったイメージを創出することが可能となり、そのためのコストの上昇を最小限に抑制できる。具体的には、インナーシェルの突出部を包み込むように張った前記表皮シートの皺が集中する突出部側位に、中間部分に内外に弾力性を備えたスリット孔を形成し、該表皮シートの一部をスリット孔の中間部分を内方へ弾性変形させながら該スリット孔内に押し込んで皺の発生を防止してなるので、表皮シートの端縁を押し込む際にスリット孔の中間部分が内方へ弾性変形して開口幅が広くなり、端縁の押し込み作業が簡単になる。
【００２２】
請求項２によれば、インナーシェルの突出部に張った表皮シートの端縁の皺を、許容される必要最小限に止めることが可能であるとともに、スリット孔内への表皮シートの端縁の押し込み作業が容易である。
【００２３】
請求項３によれば、背凭れ板を構成するインナーシェルの突出部の端面には、背凭れ支持杆が近接して取付けられるので、前記スリット孔に押し込んだ表皮シートの端縁の近傍を含めて、端面に位置する表皮シートが略隠蔽されるので、外観性に全く問題がないのである。
