Description

本発明は、背凭れや座体における枠状のフレームに、身体の背中や下半身などの荷重を支持する張材を張設してなる椅子に関する。   The present invention relates to a chair in which a tension material that supports a load such as the back of the body or the lower half of the body is stretched on a frame-like frame in a backrest or a seat.

椅子における背凭れの背当て面や座体の座面は、着座者の背中や下半身に直接接触して、その荷重を支持する部位であるため、蒸れが発生し易い。
そのため、枠状とした背凭れや座体のフレームに、メッシュ状に組成された太手撚糸からなる地組織からなる張材を張設することにより、通気性を良好にするとともに、張材を構成する緯糸の中に単糸の弾性糸を組み入れることによって、着座時に、適度な弾性変形を可能にして、快適な座り心地を得るようにしたものがある（例えば特許文献１参照）。 The backrest surface of the backrest of the chair and the seat surface of the seat are in direct contact with the back and lower body of the seated person and support the load.
For this reason, by stretching a tension material made of a thick textured yarn composed of a mesh in a frame-like backrest or seat frame, the air permeability is improved and the tension material is There is one in which a single elastic yarn is incorporated into the constituting weft to allow a suitable elastic deformation at the time of sitting so as to obtain a comfortable sitting comfort (for example, see Patent Document 1).

しかし、特許文献１に記載のものでは、背凭れの背当て面や座体の座面に張設される張材は、全体が均一な密度に組成されているため、どの部位においても、均等に弾性変形して、着座者の背中や下半身を支持するようになっている。
そのため、背凭れの腰部や、座体の臀部に相当する部位のように、着座者の背中や足などよりも、荷重に対して強い支持力を必要とする部位には、別体のランバーサポート等を設けることがある。
しかし、ランバーサポート等は、別部材であるため、コストが高くなり、また、背凭れの小さな会議用椅子等としては、コスト及びデザインの両面から不向きなものとなっている。 However, in the thing of patent document 1, since the tension material stretched on the backrest surface of the backrest or the seat surface of the seat body is composed of a uniform density as a whole, it is uniform in any part. It is elastically deformed to support the back and lower body of the seated person.
Therefore, a separate lumbar support is required for parts that require a stronger support force against the load than the back and legs of the seated person, such as the back of the back and the part corresponding to the buttocks of the seat. Etc. may be provided.
However, since the lumbar support or the like is a separate member, the cost is high, and the conference chair or the like with a small backrest is not suitable for both cost and design.

このような不具合を解消するために、従来、例えば背凭れの張材を、強い支持力が必要とされる着座者の腰部に、強い弾性抵抗を付与することができるように構成したものがある（例えば特許文献２及び３参照）。   In order to eliminate such problems, there is a conventional structure in which, for example, a backrest tension material can be provided with a strong elastic resistance to a waist of a seated person that requires a strong support force. (For example, refer to Patent Documents 2 and 3).

上記特許文献２及び３に記載の椅子における背凭れの張材は、メッシュ状の地組織と帯条部とに完全に二分し、強い支持力が必要である着座者の腰部に相当する部位に密な帯条部を対応させ、その他の部位に対しては、地組織を対応させるような構成となっている。   The backrest upholstery material in the chairs described in Patent Documents 2 and 3 is completely divided into a mesh-like ground structure and a strip portion, and a portion corresponding to a waist portion of a seated person who needs a strong support force. The structure is such that dense strips are made to correspond and the other parts are made to correspond to the ground structure.

特開２００３−１３５２００号公報JP 2003-135200 A 国際特許公開２００２−０９８２６１号公報International Patent Publication No. 2002-098261 特開２００９−１１２３６０号公報JP 2009-112360 A

しかし、上記特許文献２及び３に記載の張材では、地組織と帯条部とが隣接しているため、着座者の腰部の近傍に相当する部位において、地組織と帯条部との境界部における弾性支持力の差が極端に大きく、快適な着座感を得ることができないという問題がある。   However, in the upholstery materials described in Patent Documents 2 and 3, since the ground structure and the strip portion are adjacent to each other, the boundary between the ground tissue and the strip portion at a portion corresponding to the vicinity of the waist of the seated person. There is a problem that the difference in elastic support force at the part is extremely large, and a comfortable seating feeling cannot be obtained.

本発明は、上記問題点に鑑みてなされたもので、背凭れや座体に張設される張材を、着座者の身体における背中や下半身の荷重に対する弾性支持力を、部位ごとに極端に異ならせることなく、必要な部位において、強い弾性支持力を得ることができるようにした椅子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-mentioned problems, and the tension support material stretched on the backrest or the seat body is made extremely elastic for the load on the back or lower body of the seated person's body. An object of the present invention is to provide a chair that can obtain a strong elastic supporting force at a necessary portion without being different.

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）背凭れまたは座体における枠状のフレームに張材を張設してなる椅子であって、前記張材を、単糸または太手撚糸の少なくもいずれか一方からそれぞれなる経糸または緯糸を複数本用いて、それぞれ構成される経条及び緯条により格子状に組成した地組織の生地からなる弾性布帛をもって形成するとともに、前記地組織に、前記緯条よりも広幅の緯帯条部を、前記背凭れの上下方向または座体の前後方向の長手方向に沿って互いに離間させて複数配列し、かつこれら互いに隣り合う緯帯条部同士の配列間隔を、前記背凭れの上下端または座体の前後端から内方へ向うに従って漸次小さくなるように形成する。 According to the present invention, the above problem is solved as follows.
(1) A chair in which a tension member is stretched on a frame-like frame in a backrest or a seat, wherein the tension member is a warp or a weft consisting of at least one of a single yarn and a thick twisted yarn. Are formed with an elastic fabric made of a fabric of a ground structure composed in a lattice pattern with a warp and a weft configured respectively, and a weft strip portion having a width wider than that of the weft. Are arranged apart from each other in the vertical direction of the backrest or in the longitudinal direction of the seat body, and the interval between the weft strips adjacent to each other is the upper or lower end of the backrest or It forms so that it may become small gradually as it goes inward from the front-and-rear end of a seat.

（２）上記(１)項において、前記緯帯条部を構成する太手緯糸の本数を、背凭れの上下端または座体の前後端から内方へ向うに従って漸次増加させて、前記緯帯条部の幅を広くすることにより、緯帯条部同士の配列間隔を小さくする。 (2) In the above item (1), the number of thick wefts constituting the weft band is gradually increased from the upper and lower ends of the backrest or the front and rear ends of the seat body toward the inward direction. By increasing the width of the strips, the arrangement interval between the weft strips is reduced.

（３）上記(１)項または(２)項において、前記緯帯条部同士の配列間隔が最小となる部位近傍を、着座者における腰部または臀部の支持部とする。 (3) In the above section (1) or (2), the vicinity of the portion where the arrangement interval between the weft strips is the minimum is defined as a support part for the waist or buttocks of the seated person.

請求項１記載の発明によれば、張材を、単糸または太手撚糸の少なくもいずれか一方からそれぞれなる経糸または緯糸を複数本用いて、それぞれ構成される経条及び緯条により格子状に組成した地組織の生地からなる弾性布帛をもって形成するとともに、地組織に、緯条よりも広幅の緯帯条部を、背凭れの上下方向または座体の前後方向の長手方向に沿って互いに離間させて複数配列し、かつこれら互いに隣り合う緯帯条部同士の配列間隔を、背凭れの上下端または座体の前後端から内方へ向うに従って漸次小さくなるようにしてあるので、背凭れや座体に張設される張材を、着座者の身体における背中や下半身の荷重に対する弾性支持力を部位ごとに極端に異ならせることなく、必要な部位において強い弾性支持力を得ることができ、快適な座り心地を得ることができる。   According to the first aspect of the present invention, the tension material is formed in a lattice pattern by warps and wefts each composed of a plurality of warps or wefts each consisting of at least one of a single yarn or a thick twisted yarn. Formed with an elastic fabric composed of a fabric of the ground composition, and a weft band portion wider than the weft is formed on the ground structure along the longitudinal direction of the backrest or the longitudinal direction of the seat body. A plurality of spaced apart arrangements and the interval between adjacent weft strips are gradually reduced from the upper and lower ends of the backrest or the front and rear ends of the seat to the inward direction. The tension material stretched on the seat and the seat body can obtain strong elastic support force at the necessary part without making the elastic support force against the load of the back and lower body in the seated person's body extremely different for each part. ,comfortable It is possible to obtain a comfort.

請求項２記載の発明によれば、緯帯条部を構成する太手緯糸の本数を、背凭れの上下端または座体の前後端から内方へ向うに従って漸次増加させて、緯帯条部の幅を広くすることにより、緯帯条部同士の配列間隔を小さくしてあるので、地組織からなる張材に、密な緯帯条部を容易に設けることができる。   According to the invention described in claim 2, the number of thick wefts constituting the weft strip is gradually increased from the upper and lower ends of the backrest or the front and rear ends of the seat to the inward direction, By increasing the width, the spacing between the weft strips is reduced, so that the dense weft strips can be easily provided on the tension member made of the ground structure.

請求項３記載の発明によれば、帯部条同士の配列間隔が最小となる部位の近傍を、着座者の腰部または臀部の支持部としてあるので、弾性支持力を部位ごとに極端に異ならせることなく、必要な部位において強い弾性支持力を容易に得ることができる。   According to invention of Claim 3, since the vicinity of the site | part where the arrangement | sequence space | interval of belt | band | zone part strip | belt becomes the minimum is used as a support part of a seated person's waist | hip | lumbar part or a buttocks, it makes elastic support force different for every site | part. Therefore, a strong elastic supporting force can be easily obtained at a necessary site.

座体７は、合成樹脂製の座板８と、その上面に取付けられたクッション材９とからなり、座板８の前端両側部は、支基６の前端両側部に左右方向を向く枢軸１０をもって枢着され、座体７は、図１に示す後上向き傾斜する待機状態から、図２に示す水平または後下向き傾斜する使用位置に、枢軸１０を中心として回動可能となっている。
これにより、着座者の荷重が脚柱５よりも後方に加わり、座体７の後部により、着座者の臀部を安定よく支持することができる。 The seat body 7 includes a seat plate 8 made of synthetic resin and a cushion material 9 attached to the upper surface of the seat body 7. The seat body 7 is pivotable about the pivot shaft 10 from the standby state shown in FIG. 1 that is inclined backward and upward to the use position that is horizontally or downwardly inclined as shown in FIG.
Thereby, a seated person's load is added back rather than the pillar 5, and the seated person's buttocks can be stably supported by the rear part of the seat body 7.

座板８の後端両側部には、背凭れ１２の下端両側部が、左右方向を向く軸１１をもって枢着されている。
背凭れ１２は、図２に示すほぼ上方を向く起立位置と、この起立位置から、図３に示す後傾位置とに、軸１１を中心として回動可能となっている。 On both sides of the rear end of the seat plate 8, both sides of the lower end of the backrest 12 are pivotally attached with shafts 11 facing in the left-right direction.
The backrest 12 is rotatable about the shaft 11 from an upright position shown in FIG. 2 to a substantially upward position and a backward inclined position shown in FIG. 3 from the upright position.

FIG. 7 is a partially enlarged front view showing a mesh composed of warps and wefts constituting the texture of the fabric, and FIG. 7 shows warps and wefts constituting the texture in the corner frame B part of FIG. It is a schematic diagram which partially enlarges and shows a composition state with a strip.

図４に示すように、張材１６は、弾性布帛１７を、経条１８及び緯条１９により格子状に組成した地組織１７ａからなっている。   As shown in FIG. 4, the upholstery material 16 is composed of a ground structure 17 a in which an elastic fabric 17 is composed in a lattice shape with warps 18 and wefts 19.

経条１８及び緯条１９同士は、ほぼ同一の幅をもって格子状に組成することにより、目の均一な地組織１７ａとされている。
この地組織１７ａは、図６に示すように、経条１８と緯条１９とを格子状に組成した際に、例えば幅２ｍｍの経条１８と、幅２ｍｍの緯条１９とをそれぞれ２ｍｍの間隔を空けて格子状に組成すると、格子の中央に経・緯２ｍｍの四角形の目孔が均一に形成されるような形態を有する。 The warps 18 and the wefts 19 are formed in a lattice shape with substantially the same width, thereby forming a ground structure 17a having a uniform eye.
As shown in FIG. 6, when the warps 18 and the wefts 19 are formed in a lattice pattern, the ground structure 17 a has, for example, a 2 mm-wide warp 18 and a 2 mm-wide weft 19 of 2 mm each. When the composition is formed in a lattice form with a space, a square eye with a length of 2 mm and a latitude is uniformly formed in the center of the lattice.

左右に延びる緯条１９には、図１、図４に示すように、経方向、すなわち、背凭れ１２の上下方向に、緯条１９よりも広幅の緯帯条部２０が、緯方向、すなわち背凭れ１２の左右方向に延びるように形成されている。
前記緯帯条部２０は、地組織１７ａよりも密に構成されている。 As shown in FIGS. 1 and 4, the weft 19 extending in the left-right direction has a weft strip 20 wider than the weft 19 in the warp direction, that is, in the vertical direction of the backrest 12. The backrest 12 is formed so as to extend in the left-right direction.
The weft strip portion 20 is configured more densely than the ground structure 17a.

この緯帯条部２０は、生地の経方向に互いに離間させて複数配列され、これらの互いに経糸方向に隣り合う緯帯条部２０同士の配列間隔ｄ1，ｄ2・・・・ｄnを、背凭れ１２の上端から下方または座体７の前端から後方のほぼ中央部における着座者の腰部に相当する位置へ向うに従って一旦漸次小さくし、その最小ｄnとなった部位から漸次大きくなるような配列間隔ｄn，ｄn+1・・・・、換言すれば、背凭れ１２の上下端から内方に向かって緯帯条部２０同士の配列間隔が小さくなるような形態を有し、かつこれらの緯帯条部２０を、図５に示すように、地組織１７ａ上の表面に突出させることにより、地組織１７ａ上の表面に、複数本の緯帯条部２０により形成される配列模様（以下、これを横段模様と称する）を形成している。 The weft band ridges 20 is moved away from one another in the warp direction of the fabric are arrayed, the arrangement interval d 1, d 2 ···· d n weft band ridges 20 adjacent to these warp directions once gradually smaller as the direction from the front end of the upper end from the lower or seat support 7 of the backrest 12 to the position corresponding to the waist of the seated person at a substantially central portion of the rear, made gradually larger from the site became its minimum d n as Do arrangement interval d n, d n + 1 ···· , in other words, it has the form as the arrangement interval of the weft band ridges 20 together toward the upper and lower ends of the backrest 12 inwardly is small, Further, as shown in FIG. 5, by projecting these weft strips 20 onto the surface of the ground structure 17a, an array formed by a plurality of weft strips 20 on the surface of the ground structure 17a. A pattern (hereinafter referred to as a horizontal pattern) is formed.

この横段模様のパターンは、適用される椅子の背凭れ１６の大きさに合わせて、生地の経方向に少なくとも１回以上繰返し連続させて形成することができる。
このような複数本の緯帯条部２０の配列によって、着座者の背中を安定して支持することができる。 The horizontal pattern can be repeatedly formed at least once in the warp direction of the fabric according to the size of the backrest 16 of the chair to be applied.
The arrangement of the plurality of weft strip portions 20 can stably support the back of the seated person.

なお、前記緯帯条部２０を形成する場合には、後記する地組織１７ａにおける緯条１９の組成において、細手経糸２１と太手緯糸２３との組み合わせ、太手緯糸２３が地組織１７ａの表面から畝状に突出しうる畝織り組織に組成することにより行われる。
これにより、緯帯条部２０は、帯状段部として地組織１７ａの表面に段差を持たせて突出させることができる。 In the case of forming the weft band portion 20, in the composition of the weft 19 in the ground structure 17a to be described later, the combination of the fine warp 21 and the thick weft 23, the thick weft 23 of the ground structure 17a is used. It is carried out by composing into a knot weave structure that can protrude like a wrinkle from the surface.
As a result, the weft strip portion 20 can be protruded with a step on the surface of the ground texture 17a as a strip-shaped step portion.

すなわち、前記生地の地組織１７ａを組成するには、図７に示すように、経条１８を、複数本の単糸２１、例えば４本の細手経糸２１ａ〜２１ｄと複数本の太手撚糸２２、例えば４本の太手経糸２２ａ〜２２ｄとより構成するとともに、これらの太手経糸２２ａ〜２２ｄの両側に、細手経糸２１ａ〜２１ｄをそれぞれ２本ずつ配列する。
一方、緯条１９は、複数本の太手撚糸２３、例えば３本の太手緯糸２３ａ〜２３ｃにより構成する。
また、これら互いに経方向に隣り合う緯条１９の間の目孔となる格子間隙の中には、複数本の単糸２４、例えば３本の透明な細手緯糸２４ａ〜２４ｃが、補強糸として配列されている。 That is, in order to compose the fabric texture 17a, as shown in FIG. 7, the warp 18 is composed of a plurality of single yarns 21, for example, four fine warp yarns 21a to 21d and a plurality of thick twisted yarns. 22, for example, four thick warps 22a to 22d, and two fine warps 21a to 21d are arranged on both sides of each of these thick warps 22a to 22d.
On the other hand, the weft 19 is composed of a plurality of thick twisted yarns 23, for example, three thick wefts 23a to 23c.
In addition, a plurality of single yarns 24, for example, three transparent fine weft yarns 24a to 24c are used as reinforcing yarns in the lattice gap that becomes the eye holes between the wefts 19 adjacent to each other in the warp direction. It is arranged.

次に、生地における地組織１７ａの組成状態を説明する。
経条１８を構成する４本の細手経糸２１ａ〜２１ｄ中における一方の外側に配列される細手経糸２１ａに対しては、３本の細手緯糸２４ａ〜２４ｃが、３本の太手緯糸２３ａ〜２３ｃを３越して平織り状態に組織される。
他方の外側に配列される細手経糸２１ｄに対しては、３本の細手緯糸２４ａ〜２４ｃ及び３本の太手緯糸２３ａ〜２３ｃが平織り状態に組織される。 Next, the composition state of the ground tissue 17a in the fabric will be described.
For the fine warp yarns 21a arranged outside one of the four fine warp yarns 21a to 21d constituting the warp 18, the three fine weft yarns 24a to 24c are three thick weft yarns. It is organized in a plain weave state over 3 through 23a-23c.
For the fine warp yarns 21d arranged on the other outer side, three fine weft yarns 24a to 24c and three thick weft yarns 23a to 23c are organized in a plain weave state.

経条１８を構成する４本の太手縦糸２２ａ〜２２ｄに対しては、３本の細手緯糸２４ａ〜２４ｃ及び３本の太手緯糸２３ａ〜２３ｃがそれぞれ交互に平織り状態に組織されるとともに、４本の太手縦糸２２ａ〜２２ｄ中における外側２本の太手経糸２２ａ，２２ｄは、４本の細手経糸２１ａ〜２１ｄ中における内側２本の細手経糸２１ｂ及び２１ｄに対して、それぞれ綟織り状態に絡ませて組織される。
これにより、生地の地組織１７ａを、経条１８と緯条１９とにより格子状に組成するとともに、組成後の経条１８が緯方向にずれたり、緯条１９が経方向にずれたりすることなく、格子形態を確実に保持しうるように組織されている。 For the four thick warps 22a to 22d constituting the warp 18, the three fine wefts 24a to 24c and the three thick wefts 23a to 23c are alternately organized in a plain weave state. The two outer thick warps 22a and 22d in the four thick warps 22a to 22d are respectively compared to the inner two thin warps 21b and 21d in the four thin warps 21a to 21d. Organized in a woven state.
As a result, the fabric texture 17a is composed in a lattice pattern with the warps 18 and the wefts 19, and the warp 18 after the composition is displaced in the weft direction, or the wefts 19 are displaced in the warp direction. It is structured so that the lattice form can be securely held.

上記した張材１６における生地の地組織１７ａを構成する緯条１９を、部分的に地組織１７ａの表面に突出しうる緯帯条部２０に形成するには、例えば図７に示す緯条１９における経方向の両側に、太手緯糸２３を２本ずつ重ね合わせるとともに、これらの太手緯糸２３を、緯条１９の織成工程中に、必要に応じて補強糸となる細手緯糸２４を補充しながら組み入れて、緯条１９を構成する太手緯糸２３と共に畝織り組織でもって組成することにより行われる。
また、互いに経方向に隣り合う緯帯条部２０同士の配列間隔ｄ1，ｄ2・・・・ｄnを、背凭れ１２の上端から下方のほぼ中央部における着座者の腰部に相当する位置へ向うに従って漸次小さくするには、各緯帯条部２０の幅ｓ1，ｓ2・・・・ｓnを、太手緯糸２３の本数を部分的に増加させると同時に、緯帯条部２０間における経方向の目数を漸次減少させることにより行われる。
さらに、緯帯条部２０同士の配列間隔が最小ｄnで、かつ緯帯条部２０の幅が最広ｓnな部位から緯帯条部２０同士の配列間隔ｄn，ｄn+1・・・を漸次大きくするには、太手緯糸２３の本数を部分的に減少させると同時に、緯帯条部２０間における地組織１７ａの経方向の目数を漸次増加させることにより行われる。
この場合、例えば背凭れ１２の上部のように、緯帯条部２０同士の配列間隔ｄ1，ｄ2が広く、緯帯条部２０の幅ｓ1，ｓ2が狭くてほぼ等しい部位においては、互いに経方向に隣り合う緯帯条部２０間における地組織１７ａの経方向の目数のみを減少させることにより、緯帯条部２０同士の配列間隔を部分的に漸次小さくすることも可能である。 In order to form the wefts 19 constituting the fabric texture 17a of the upholstery material 16 on the weft bands 20 that can partially protrude from the surface of the texture 17a, for example, in the wefts 19 shown in FIG. Two thick wefts 23 are overlapped on both sides in the warp direction, and these thick wefts 23 are supplemented with fine wefts 24 as reinforcing yarns as needed during the weft 19 weaving process. However, it is performed by composing with a thick weave 23 together with a thick weft 23 constituting the weft 19.
Also, equivalent sequences distance d 1, d 2 ···· d n between the weft band ridges 20 adjacent to the warp direction from each other, the seated person's waist from the upper end of the backrest 12 at the substantially central portion of the lower position to gradually smaller as toward to the width s 1, s 2 ···· s n of the weft Obijo unit 20, the partially increase the number of Futoshite weft 23 at the same time, Nukitaijo 20 This is done by gradually decreasing the number of eyes in the warp direction between them.
Furthermore, the arrangement interval between the Nukitaijo portion 20 with minimal d n, and the arrangement interval of the weft band ridges 20 between the width of Nukitai strip portion 20 from the widest s n sites d n, d n + 1 · In order to gradually increase the diameter, the number of thick wefts 23 is partially reduced, and at the same time, the number of meshes in the longitudinal direction of the ground structure 17a between the weft strips 20 is gradually increased.
In this case, for example, in an upper part of the backrest 12, the arrangement intervals d 1 and d 2 between the weft strips 20 are wide and the widths s 1 and s 2 of the weft strips 20 are narrow and almost equal. In addition, by reducing only the number of meshes in the longitudinal direction of the ground structure 17a between the weft strips 20 adjacent to each other in the warp direction, it is also possible to partially reduce the array interval between the weft strips 20 partly. is there.

なお、上記の実施形態では、椅子の背凭れに張設される張材を例に説明したが、座体などに張設される張材や大型のパネルなどの大きな家具の目隠し部材にも適用することも可能である。
座体の場合には、横段模様を形成する各緯帯条部２０同士の配列間隔ｄ1，ｄ2・・・・ｄnを、座体の前端から後方における着座者の臀部に相当する部位へ向うに従って一旦漸次小さくなるように配列し、その後の配列間隔ｄn，ｄn+1・・・・を漸次大きくなるように配列、換言すれば、座体の前後端から内方に向かって緯帯条部２０同士の配列間隔が小さくなるように配列することにより、着座者の臀部を安定して支持することができる。 In the above-described embodiment, the tension material stretched on the backrest of the chair has been described as an example. However, the present invention is also applicable to a large-sized panel such as a tension material stretched on a seat body or a large panel. It is also possible to do.
When the seat body, the arrangement interval d 1, d 2 ···· d n of each weft Obijo 20 together to form the widthwise corrugation pattern, which corresponds to the buttocks of the seated person in the rear from the front end of the seat support arranged once to become gradually smaller as toward to the site, then the arrangement interval d n, arranged so that progressively increasing the d n + 1 · · · ·, in other words, toward the front and rear ends of the seat body inwardly Thus, by arranging so that the arrangement interval between the weft strip portions 20 becomes small, the seated person's buttocks can be stably supported.
