しかして本実施形態では、前記座3を構成する張地32の前記座フレーム31への張設箇所と異なる箇所を裏側、換言すれば下方に向けて牽引する牽引手段5をさらに備えている。   Thus, in the present embodiment, there is further provided traction means 5 for towing a portion different from the portion where the stretched fabric 32 constituting the seat 3 is stretched to the seat frame 31, in other words, downward.

この牽引手段5は、図2及び図5に示すように、前記張地32の裏面に配された牽引部51と、この牽引部51を保持する保持部52とを備えている。   As shown in FIGS. 2 and 5, the traction means 5 includes a traction portion 51 disposed on the back surface of the stretched fabric 32 and a holding portion 52 that holds the traction portion 51.

さらに詳述すると、図2及び図5に示すように、前記牽引部51は、張地32の後部の幅方向中央部の裏面、換言すれば座面の後部の幅方向中央部の裏側に配され張地32と同一材質の織物により形成されたシート状の部材であり、その上端部を張地32に縫い付けることにより張地32と一体に形成している。   More specifically, as shown in FIGS. 2 and 5, the traction portion 51 is arranged on the back surface of the center portion in the width direction of the rear portion of the stretch 32, in other words, on the back side of the center portion in the width direction of the rear portion of the seat surface. This is a sheet-like member formed of a woven fabric made of the same material as the upholstery 32, and is formed integrally with the upholstery 32 by sewing the upper end portion of the upholstery 32.

前記保持部52は、図2及び図5に示すように、前記座内フレーム33の後内枠部333の幅方向中央部から前下方に延伸させて一体に設けられており、その先端部に前記牽引部51の下端部を保持する。そして、この保持部52に前記牽引部51の下端部を保持させることにより、張地32が弾性変形し、前記牽引部51の上端に隣接する部位すなわち座3の後部の幅方向中央部に凹部が形成される。   As shown in FIGS. 2 and 5, the holding portion 52 is integrally provided extending from the center in the width direction of the rear inner frame portion 333 of the in-seat frame 33 to the front lower side, and is provided at the tip portion thereof. The lower end portion of the pulling portion 51 is held. Then, by holding the lower end portion of the traction portion 51 on the holding portion 52, the tension fabric 32 is elastically deformed, and a concave portion is formed in a portion adjacent to the upper end of the traction portion 51, that is, the widthwise central portion of the rear portion of the seat 3. Is formed.

そして、前記背凭れ4は、図1に示すように、外周部を構成する背フレーム41と、この背フレーム41の内側に張設された張地42と、この張地42の裏側に配されて前記背フレーム41との間で前記張地42を挟持する図示しない背内フレームとを備えており、従来のこの種の椅子の背凭れとして周知のものと同様の構成を有する。また、この背凭れ4は、その裏面すなわち後面を背凭れ支持部43により支持されている。この背凭れ支持部43は、脚体2の後部に位置する脚支柱22の上端から一体的に延長させて設けている。   As shown in FIG. 1, the backrest 4 is arranged on the back frame 41 constituting the outer peripheral portion, the tension fabric 42 stretched inside the spine frame 41, and the back side of the tension fabric 42. And a back inner frame (not shown) that sandwiches the upholstery 42 with the back frame 41, and has the same configuration as a well-known backrest of this type of chair. The backrest 4 is supported by a backrest support portion 43 on the back surface, that is, the rear surface. The backrest support portion 43 is provided so as to be integrally extended from the upper end of the leg support 22 located at the rear portion of the leg 2.

以上に述べたように、本実施形態に係る構成によれば、牽引手段5により座3の後部の幅方向中央部が裏側に向けて牽引されて凹部が形成されるので、座フレーム31の内側に張設された張地32の表面により座面を形成する態様を採用しつつ、座面に凹凸を設けて該座面を立体的なものとすることができる。また、張地32に与える張力や張地32を構成する縦糸又は横糸の弾性係数を部位によって変化させる態様と比較して、張地32全体を同一の素材により形成しフレームの内側に張地32を張設する際には全体に同一の張力を与えるようにしても上述した効果が得られるので、製造に掛かる手間を大幅に削減できる。   As described above, according to the configuration according to the present embodiment, the central portion in the width direction of the rear portion of the seat 3 is pulled toward the back side by the pulling means 5, so that a recess is formed. While adopting a mode in which the seat surface is formed by the surface of the tension fabric 32 stretched on the seat surface, the seat surface can be made three-dimensional by providing irregularities on the seat surface. In addition, as compared with an aspect in which the tension applied to the upholstery 32 and the elastic coefficient of the warp or weft constituting the upholstery 32 are changed depending on the part, the entire upholstery 32 is formed of the same material, and the upholstery 32 is provided inside the frame. Even when the same tension is applied to the whole, the above-described effect can be obtained, so that labor required for manufacturing can be greatly reduced.

また、前記牽引手段5が、張地32の裏面に設けられた牽引部51と、この牽引部51を保持する保持部52とを備えているので、上述したような構成を無理なく実現できる。   Moreover, since the said traction means 5 is provided with the traction part 51 provided in the back surface of the tension fabric 32, and the holding | maintenance part 52 which hold | maintains this traction part 51, the above structures can be implement | achieved reasonably.

さらに、前記張地32の裏側に配されて前記フレームとの間で前記張地32を挟持する座内フレーム33をさらに備え、この座内フレーム33に前記牽引手段5の保持部52を一体に設けているので、前段で述べたような牽引手段5を大幅な設計変更を伴うことなく実現することができる。   The seat frame 33 further includes an in-seat frame 33 disposed on the back side of the upholstery 32 and sandwiching the upholstery 32 with the frame, and the holding portion 52 of the traction means 5 is integrated with the in-seat frame 33. Since it is provided, the traction means 5 as described in the previous stage can be realized without significant design change.

加えて、上述したように、前記牽引手段5が、座3の後部の幅方向中央部を裏側に向けて牽引するので、座面に凹凸を設けて着座感の向上を図ることができる。   In addition, as described above, the pulling means 5 pulls the central portion in the width direction of the rear part of the seat 3 toward the back side, so that the seating surface can be provided with unevenness to improve the seating feeling.

そして、張地32を構成する縦糸及び横糸がいずれも弾性糸であるので、着座者から荷重を受けることにより張地32が弾性変形可能である。従って、着座感の向上を図ることができる。   Since both the warp and the weft constituting the upholstery 32 are elastic yarns, the upholstery 32 can be elastically deformed by receiving a load from a seated person. Therefore, the seating feeling can be improved.

That is, the left seat frame A41 and the left back frame A51, and the right seat frame A41 and the right back frame A51 are each integrally formed by integrally molding a single continuous metal material.

前記左のフレームF及び右のフレームFの各外側面Faには、図6及び図7に示すように、前記座張地A42及び前記背張地A52を取り付けるための取付溝Fdが形成されている。これらの取付溝Fdは、前記各フレームFの裏面Fbよりも表面Fcに近い位置に配されている。ここで、裏面Fbとは、座フレームA41の場合には下面を意味し、背フレームA51の場合には背面を意味する。また、表面Fcとは、座フレームA41の場合には上面を意味し、背フレームA51の場合には前面を意味する。   As shown in FIGS. 6 and 7, mounting grooves Fd for mounting the seating ground A42 and the backrest A52 are formed on the outer side surfaces Fa of the left frame F and the right frame F, respectively. Yes. These mounting grooves Fd are arranged at positions closer to the front surface Fc than the back surface Fb of each frame F. Here, the back surface Fb means the bottom surface in the case of the seat frame A41, and means the back surface in the case of the back frame A51. The front surface Fc means the upper surface in the case of the seat frame A41, and the front surface in the case of the back frame A51.

前記座張地A42及び前記背張地A52(以下、「張地M」と総称する場合がある)は、図6及び図7に示すように、合成樹脂製の糸を織成または編成してなるメッシュ状の張地素材を所定形状に裁断することにより一体に構成されており、着座面である表面Ma側から裏面Mb側に存在するものを視認することができるような透光性を備えている。また、この張地Mを構成する縦糸及び横糸は、いずれも弾性糸である。   As shown in FIG. 6 and FIG. 7, the seated fabric A42 and the backed fabric A52 (hereinafter may be collectively referred to as “tension fabric M”) are made by weaving or knitting synthetic resin yarns. The mesh-like upholstery material is integrally formed by cutting it into a predetermined shape, and has a translucency so that what is present on the back surface Mb side from the front surface Ma side which is the seating surface can be visually recognized. ing. Moreover, both the warp and the weft constituting the tension fabric M are elastic yarns.

この張地Mの左右両縁部Mcには、図示は省略するが、帯状をなす剛性のある押し込み材が設けられている。この押し込み材は、前記張地Mの縁部Mcに沿って連続して設けられたものであり、前記張地Mの縁部Mcの一面側、すなわち裏面Mb側に縫製等により添着されている。また、この押し込み材は、合成樹脂等により作られたもので、前記取付溝Fdに挿入可能な厚み寸法を有するとともに、前記取付溝Fdの奥行き方向の開口寸法よりも大きな幅寸法を有したものである。   The left and right edge portions Mc of the stretch fabric M are provided with a push-in member having a belt-like shape, although illustration is omitted. This pushing material is provided continuously along the edge Mc of the upholstery M, and is attached to one side of the edge Mc of the upholstery M, that is, the back Mb by sewing or the like. . The pushing material is made of synthetic resin or the like, has a thickness dimension that can be inserted into the mounting groove Fd, and has a width dimension larger than the opening dimension in the depth direction of the mounting groove Fd. It is.

そして、図6〜図8に示すように、この張地Mの各縁部Mcを前記押し込み材とともに前記フレームFの外面Fa側に設けられた取付溝Fdに反転させて挿入することにより、当該張地Mを左右のフレームF間に張設している。この状態で、左右のフレームF間に前横梁A43、上横梁A53及び下横梁A54を介在させることによって前記張地Mに張力が付与される。このようにして張力を付与された張地Mは、左右のフレームFの形状に沿った形態となる。すなわち、左右の背フレームA51は、下端の近傍に着座A4者の腰形状に対応して前方に突出する突出部を有したものであり、前記背張地A52が下横梁A54により張力を付与されることにより前記突出部に対応した突出形状をなすように張設されている。   Then, as shown in FIG. 6 to FIG. 8, each edge Mc of the stretch fabric M is inserted into the mounting groove Fd provided on the outer surface Fa side of the frame F together with the pushing material, thereby inserting the edge Mc. A tension fabric M is stretched between the left and right frames F. In this state, a tension is applied to the tension fabric M by interposing the front horizontal beam A43, the upper horizontal beam A53, and the lower horizontal beam A54 between the left and right frames F. The tension fabric M to which tension is applied in this way is in a form along the shape of the left and right frames F. That is, the left and right back frames A51 have protrusions protruding forward corresponding to the waist shape of the seated A4 in the vicinity of the lower end, and the backrest A52 is tensioned by the lower horizontal beam A54. Thus, it is stretched so as to form a protruding shape corresponding to the protruding portion.

上述したように、この椅子A1は座A4と背凭れA5とが一体に構成されており、これら座A4及び背凭れA5が前記支持基部A3に一体に設けられた前横梁A43によって片持ち支持されている。そして、この支持基部A3と前記座A4との間に荷物載置面A6aが設けられ、その荷物載置面A6aと前記座A4の裏面との間に荷物を出し入れ自在に収容するための荷物収容空間が形成されている。前記荷物載置面A6aは、前横梁A43の平坦部の上面と支持基部A3の上に着脱可能に装着された棚板A6の上面により形成されている。   As described above, the chair A1 is configured such that the seat A4 and the backrest A5 are integrally formed, and the seat A4 and the backrest A5 are cantilevered by the front transverse beam A43 integrally provided on the support base A3. ing. A load placement surface A6a is provided between the support base A3 and the seat A4, and a load storage for freely loading and unloading the load between the load placement surface A6a and the back surface of the seat A4. A space is formed. The luggage placement surface A6a is formed by the upper surface of the flat portion of the front cross beam A43 and the upper surface of a shelf board A6 that is detachably mounted on the support base A3.

しかして本実施形態では、図8に示すように、座張地A42の前記座フレームA41への張設箇所と異なる箇所を裏側に向けて牽引する牽引手段A7をさらに備えている。この牽引手段A7は、張地Mの裏面、より具体的には座張地A42の裏面に配された牽引部A71と、この牽引部A71を保持する保持部A72とを備えている。   Accordingly, in the present embodiment, as shown in FIG. 8, there is further provided traction means A7 for towing a portion different from the stretched portion of the seating ground A42 to the seat frame A41 toward the back side. The traction means A7 includes a traction portion A71 disposed on the back surface of the tension fabric M, more specifically, the back surface of the seating fabric A42, and a holding portion A72 that holds the traction portion A71.

さらに詳述すると、前記牽引部A71は、図8に示すように、座張地A42の後部の幅方向中央部の裏面、換言すれば座面の後部の幅方向中央部の裏側に配され張地M(座張地A42)と同一材質の織物により形成されたシート状の部材であり、その上端部を張地M(座張地A42)に縫い付けることにより張地M(座張地A42)と一体に形成している。   More specifically, as shown in FIG. 8, the traction part A71 is arranged on the back surface of the center part in the width direction of the rear part of the seating area A42, in other words, on the back side of the center part in the width direction of the rear part of the seat surface. It is a sheet-like member formed of a woven fabric made of the same material as the ground M (sitting ground A42), and the upper end of the ground M is sewn to the stretched ground M (sitting ground A42). ).

前記保持部A72は、図8に示すように、前記棚板A6の後端に設けられている。換言すれば、この保持部A72は、支持基部A3に間接的に設けられている。そして、この保持部A72に前記牽引部A71の下端部を保持させることにより、張地M(座張地A42)が弾性変形し、前記牽引部A71の上端に隣接する部位すなわち座A4の後部の幅方向中央部に凹部が形成される。   As shown in FIG. 8, the holding portion A72 is provided at the rear end of the shelf board A6. In other words, the holding portion A72 is indirectly provided on the support base A3. Then, the holding portion A72 holds the lower end portion of the traction portion A71, so that the tension fabric M (the seat tension fabric A42) is elastically deformed, and the portion adjacent to the upper end of the traction portion A71, that is, the rear portion of the seat A4. A recess is formed at the center in the width direction.

以上に述べたように、本実施形態に係る構成によっても、牽引手段A7により座A4の後部の幅方向中央部が裏側に向けて牽引されて凹部が形成されるので、座フレームA41の内側に張設された座張地A42の表面により座面を形成する態様を採用しつつ、座面に凹凸を設けて該座面を立体的なものとすることができる。また、座張地A42に与える張力や座張地A42を構成する縦糸又は横糸の弾性係数を部位によって変化させる態様と比較して、座張地A42全体を同一の素材により形成し座フレームA41の内側に座張地A42を張設する際には全体に同一の張力を与えるようにしても上述した効果が得られるので、製造に掛かる手間を大幅に削減できる。   As described above, even in the configuration according to the present embodiment, the central portion in the width direction of the rear portion of the seat A4 is pulled toward the back side by the pulling means A7, so that a recess is formed. While adopting a mode in which the seat surface is formed by the surface of the stretched seat stretch A42, the seat surface can be made three-dimensional by providing irregularities on the seat surface. Further, compared to the aspect in which the tension applied to the seating fabric A42 and the elastic coefficient of the warp or weft constituting the seating fabric A42 are changed depending on the part, the entire seating fabric A42 is formed of the same material, and the seat frame A41. Since the above-described effect can be obtained even when the same tension is applied to the whole when the seating ground A42 is stretched on the inner side, labor for manufacturing can be greatly reduced.

また、前記牽引手段A7が、張地の裏面に配された牽引部A71と、この牽引部A71を保持する保持部A72とを備えているので、上述したような構成を無理なく実現できる。   Moreover, since the said traction means A7 is provided with the traction part A71 arranged on the back surface of the upholstery and the holding part A72 that holds the traction part A71, the above-described configuration can be realized without difficulty.

加えて、座A4を下方から支持する支持基部A3を備え、この支持基部A3に前記保持部A72を間接的に設けているので、前段で述べたような牽引手段A7を大幅な設計変更を伴うことなく実現することができる。   In addition, since the support base A3 that supports the seat A4 from below is provided and the support A72 is indirectly provided on the support base A3, the traction means A7 as described in the previous stage is accompanied by a significant design change. It can be realized without.

そして、張地M(座張地A42)を構成する縦糸及び横糸が、いずれも弾性糸であるので、着座者から荷重を受けることにより張地が弾性変形可能である。従って、着座感の向上を図ることができる。   Since the warp and weft constituting the upholstery M (the upholstery A42) are both elastic yarns, the upholstery can be elastically deformed by receiving a load from the seated person. Therefore, the seating feeling can be improved.

なお、本発明は以上に述べた実施形態に限らない。   The present invention is not limited to the embodiment described above.

例えば、上述した第一及び第二実施形態では、張地の裏面に設けられ張地と同一材質の織物により形成されたシート状の牽引部と、この牽引部を保持する保持部とを備えている牽引手段を採用しているが、例えば、図9に示すように、牽引部に代えて、基端部を張地に固着しているとともに先端部を保持部52に固定可能な紐状の牽引部53を採用してもよい。この牽引部52は、1本の紐の両端部をそれぞれ張地に縫い付け中間部を保持部に保持させる態様のものである。なお、この態様において、その他の部位は第一実施形態に係るものと同様の構成を有するため、図9において、第一実施形態に係るものに対応する各部位には同一の符号を付している。紐状の牽引部としては、その他、左右1対の紐を利用したものであって対をなす紐の一端部をそれぞれ張地に縫い付け他端部同士を結合した状態で保持部に保持させる態様のもの等、種々の態様のものが考えられる。   For example, in the first and second embodiments described above, a sheet-like traction portion that is provided on the back surface of the tension fabric and formed of a fabric made of the same material as the tension fabric, and a holding portion that holds the traction portion are provided. For example, as shown in FIG. 9, instead of the traction portion, the base end portion is fixed to the tension fabric and the distal end portion can be fixed to the holding portion 52 as shown in FIG. The traction part 53 may be adopted. The pulling portion 52 is configured to sew both ends of a single string on a stretched fabric and hold the intermediate portion on the holding portion. In addition, in this aspect, since the other site | part has the structure similar to what concerns on 1st embodiment, in FIG. 9, each site | part corresponding to what concerns on 1st embodiment attaches | subjects the same code | symbol. Yes. In addition, as the string-like traction part, one pair of left and right strings is used, and one end part of the paired string is sewn to the tension fabric, and the other end part is coupled and held by the holding part. Various embodiments are possible, such as embodiments.

また、座の後部の幅方向中央部に牽引手段を設ける態様に限らず、例えば背凭れの下部の幅方向中央部に牽引手段を設ける等、凹部を設けることにより着座感の向上が見込めるその他の箇所に牽引手段を設けてももちろんよい。   Further, the present invention is not limited to a mode in which the traction means is provided in the central portion in the width direction of the rear portion of the seat. Of course, traction means may be provided at the location.

さらに、上述した第一及び第二実施形態では、張地を構成する縦糸及び横糸がいずれも弾性糸である構成を採用しているが、縦糸と横糸とのうちいずれか一方のみが弾性糸である構成を採用しても、着座者から荷重を受けることにより張地が弾性変形するので、着座感の向上をある程度図ることができる。   Further, in the first and second embodiments described above, the warp and weft constituting the tension fabric are both elastic yarns, but only one of the warp and weft is elastic. Even if a certain configuration is adopted, the tension of the stretch fabric is elastically deformed by receiving a load from the seated person, so that the seating feeling can be improved to some extent.

その他、本発明の趣旨を損ねない範囲で種々に変形してよい。   In addition, various modifications may be made without departing from the spirit of the present invention.
