Description

本発明は椅子に係り、特に椅子の表面を構成する布カバーを取り付けるための布張り構造に関する。   The present invention relates to a chair, and more particularly, to a cloth tension structure for attaching a cloth cover constituting a surface of a chair.

昨今のオフィス用椅子は、用途が多様化されており、求められるデザインテイストも様々になっている。   Today's office chairs are used for various purposes, and the required design tastes are various.

製造コストなどの経済性を保ちながらバリエーションを増すためには、共通部材を使用しながら多くのニーズに合わせてテイストを変えられることが必要となる。   In order to increase variations while maintaining economic efficiency such as manufacturing costs, it is necessary to be able to change the taste according to many needs while using a common member.

他方、エコロジーの観点からも、簡単に部材の付け替えが可能でありながら、廃棄時には材料別の分別解体が容易であることが要求される。   On the other hand, from the point of view of ecology, it is required that the material can be easily replaced and the material can be easily separated and disassembled at the time of disposal.

このようなことから、椅子の背もたれの場合、脚上の受台に後傾自在に支持された背フレームに背もたれ形状に形成された芯材を設け、この芯材の上方から袋状に縫成された布カバーを被せ、布カバーの開口部をスライドファスナーや平面ファスナーなどで綴じ合わせることにより布カバーを芯材に取り付けるようになされたものが提案されている（特許文献１参照）。   For this reason, in the case of a chair backrest, a core material formed in a backrest shape is provided on a back frame that is supported by a pedestal on a leg so as to be able to tilt backward, and is sewn in a bag shape from above the core material. There has been proposed a technique in which a cloth cover is attached to a core member by covering the cloth cover and binding the opening of the cloth cover with a slide fastener or a flat fastener (see Patent Document 1).

あるいはタッカーにより布カバーを芯材に止め付けるようにしたものもある。   Alternatively, there is one in which the cloth cover is fixed to the core material by a tucker.

しかるに布カバーを綴じ合わせるためのスライドファスナーは金属材料を含み、平面ファスナーは合成樹脂製であるため、布カバーを交換したのち廃棄するときこれらファスナーを布カバーから取り除かなければならず、その分別作業に多くの手数を要するという問題がある。   However, since the slide fastener for binding the cloth cover includes a metal material and the flat fastener is made of synthetic resin, the fastener must be removed from the cloth cover when the cloth cover is replaced and discarded. There is a problem that a lot of work is required.

またタッカーにによるものは、タッカーが打ち込まれて圧入されているため、これを取り外すことが容易でなく、布カバーの交換が煩わしく、分別作業も容易でない。
特開２００３−７９４８７号公報 Moreover, since the tucker is driven and press-fitted, it is not easy to remove the tucker, the cloth cover is troublesome to replace, and the sorting work is not easy.
JP 2003-79487 A

本発明は、椅子の骨格は共通構造とし、表面材である布カバーで被包することにより、色彩、質感その他多種のニーズに容易に応えることができ、かつ廃棄時の交換作業、材質別の分別作業を容易とし、構成の簡素化に加え作業性の大幅な改善を図ることを課題とするものである。   In the present invention, the skeleton of the chair has a common structure, and it can be easily responded to various needs such as color, texture, etc. by enclosing it with a cloth cover which is a surface material. It is an object of the present invention to make the sorting work easy and to improve the workability significantly in addition to simplifying the configuration.

上記課題を解決するための手段として本発明は、脚柱に支持される受台に後傾動自在に支持された背フレームの立ち上げ部に背もたれ形状の芯材を取り付け、この芯材の背当て面側にウレタンフォーム等のクッション材を添着し、このクッション材を含む芯材に布カバーを被せて背もたれとする椅子において、前記芯材の複数箇所に鉤状突起を設け、袋状に形成された布カバーを芯材に被せて布カバーの布地を前記鉤状突起に引っ掛けて固定し、この鉤状突起の存在部分を合成樹脂製化粧カバーで覆い、この化粧カバーと芯材により布カバーのしわ切りと鉤状突起の隠蔽とをなさしめるようにしたことにある。   As a means for solving the above-mentioned problems, the present invention attaches a backrest-shaped core material to a rising portion of a back frame that is supported by a pedestal supported by a pedestal so that it can be tilted rearwardly. In a chair with a cushioning material such as urethane foam attached to the surface side and a core cover including this cushioning material covered with a cloth cover, the backrest is provided with a plurality of hook-like projections at a plurality of locations on the core material. The cloth cover is covered with a core material, and the fabric of the cloth cover is hooked and fixed on the hook-shaped protrusion, and the existing portion of the hook-shaped protrusion is covered with a synthetic resin decorative cover, and the cloth cover is covered with the decorative cover and the core material. This is because wrinkling and hiding of the hook-shaped projections are performed.

請求項２は、前記布カバーの前記鉤状突起に対応する位置に係合孔を設け、この係合孔を鉤状突起に係合して芯材に布カバーを取り付けるようにしたことにある。   According to a second aspect of the present invention, an engagement hole is provided at a position corresponding to the hook-shaped protrusion of the cloth cover, and the engagement hole is engaged with the hook-shaped protrusion to attach the cloth cover to the core material. .

請求項３は、前記の椅子において、布カバーの下端部に前記鉤状片が係合する係合孔を形成し、前記クッション材を含む芯材に布カバーを被せたのち前記鉤状片をテンションを加えて前記係合孔に係着し、前記芯材の下端に前記鉤状片の係着部を隠蔽する下カバーを取り付けるようにしたものである。   According to a third aspect of the present invention, in the chair described above, an engagement hole for engaging the hook-shaped piece is formed at a lower end portion of the cloth cover, and the hook-shaped piece is attached to the core material including the cushion material after the cloth cover is covered. A tension is applied to engage with the engagement hole, and a lower cover for concealing the engagement portion of the hook-shaped piece is attached to the lower end of the core member.

請求項４は、前記の椅子において、芯材の下端部に複数個の係合孔を形成し、前記クッション材を含む芯材に布カバーを被せたのち前記係合孔にピンにより布カバーの布地を共に押し込んで固定し、前記芯材の下端に前記ピンによる係着部を隠蔽する下カバーを取り付けるようにしたものである。   According to a fourth aspect of the present invention, in the chair described above, a plurality of engagement holes are formed in a lower end portion of the core member, and the cloth cover is covered with the core member including the cushion member, and then the engagement cover is pinned by a pin. The fabric is pushed together and fixed, and a lower cover for concealing the engaging portion by the pin is attached to the lower end of the core material.

請求項１、２記載の発明によれば、布カバーを芯材に被せたのち布カバーの布地を芯材に設けた鉤状突起に引っ掛けるだけで布カバーの取り付けができるので、布カバーの取り付けに際し特別な工具類を用いる必要がなく、取り付け作業を至って容易に行うことができる。   According to the first and second aspects of the invention, since the cloth cover can be attached only by hooking the cloth cover onto the core material and then hooking the cloth cover on the hook-shaped protrusion provided on the core material, the cloth cover can be attached. At this time, it is not necessary to use special tools, and the attachment work can be easily performed.

また布カバーの交換や廃棄時には、化粧カバーを外して布カバーを鉤状突起から外すだけで取り外すことができるのでその作業が容易であり、取り外したのちは布カバーに異種材質の部材が付帯していないので分別作業が不要であり、廃棄時の処理が容易にでき、エコロジーの観点からもきわめて有用である。   Also, when replacing or disposing of the cloth cover, it can be removed simply by removing the decorative cover and removing the cloth cover from the hook-shaped projections. Therefore, separation work is not necessary, disposal at the time of disposal is easy, and it is extremely useful from the viewpoint of ecology.

布カバーを取り付けたのちは、鉤状突起による係着部分は化粧カバーで隠蔽されているので外部からは全く見えず、椅子としてのデザインを損なうこともない。   After attaching the cloth cover, the engaging part by the hook-like projection is hidden by the decorative cover, so it cannot be seen from the outside at all, and the design as a chair is not impaired.

請求項３によれば、下カバーを外し、布カバーの下端部の筒状部に挿入された鉤状片を芯材側の係合孔から抜くだけで解体することができ、また鉤状片を筒状部から抜くだけで鉤状片を布カバーから簡単に取り外すことができるので分別作業を容易に行うことができる。   According to the third aspect, it is possible to disassemble the hook-shaped piece simply by removing the lower cover and removing the hook-shaped piece inserted into the cylindrical portion at the lower end of the cloth cover from the engagement hole on the core material side. Since the hook-shaped piece can be easily removed from the cloth cover by simply pulling out the tube from the cylindrical portion, the separation work can be easily performed.

請求項４によれば、同じく下カバーを外し、ピンを抜き外せば布カバーを取り外すことができ、ピンは布カバーの布地に挿通しているだけであるから簡単に抜き取ることができ、分解作業を容易に行うことができる。   According to claim 4, the cloth cover can be removed by removing the lower cover and removing the pin, and the pin can be easily removed because it is only inserted through the fabric of the cloth cover. Can be easily performed.

図１〜図６は本発明の一実施形態を示すもので、図１は本発明を適用した椅子の側面図、図２は同正面図を示しており、この椅子自体の構成は一般にオフィスで使用されるものを対象としている。   1 to 6 show an embodiment of the present invention. FIG. 1 is a side view of a chair to which the present invention is applied. FIG. 2 is a front view of the chair. Intended for use.

この椅子の構成の概要は、キャスタ付きの脚１に立設された脚柱２に高さ調節および回転可能に支持される受台３と、この受台３に後傾動自在に支持され後部が上方に立ち上がる立ち上げ部４ａとされた背フレーム４と、前記受台３上に設置される座部５と、前記背フレーム４の立ち上げ部４ａに支持される背もたれ６とで構成されている。   The outline of the configuration of this chair is as follows: a pedestal 3 supported on a pedestal 2 standing on a leg 1 with casters so that the height can be adjusted and rotated; The back frame 4 is a rising portion 4 a that rises upward, the seat portion 5 that is installed on the cradle 3, and the backrest 6 that is supported by the rising portion 4 a of the back frame 4. .

前記背もたれ６は、前記背フレーム４の立ち上げ部４ａに一体的に設けられ背もたれ形状に形成された樹脂製板状の芯材７と、この芯材７の背当て面側に添設されるウレタンフォーム等の弾性体からなるクッション材８と、このクッション材８を含んで芯材７の上方から被せられる袋状に形成された布カバー９とで構成され、前記芯材７の下端には前記背フレーム４と実質的に一体とされたアルミ製の下フレーム１０が設けられている。   The backrest 6 is provided integrally with the raised portion 4a of the back frame 4 and is made of a resin plate-like core material 7 formed in a backrest shape, and is attached to the backrest surface side of the core material 7. A cushion material 8 made of an elastic material such as urethane foam, and a cloth cover 9 formed in a bag shape including the cushion material 8 from above the core material 7, An aluminum lower frame 10 which is substantially integrated with the back frame 4 is provided.

上記実施形態においては、前記芯材７の背面の下半部領域７ａの周辺域に図３に示すように互いに所要の間隔をおいて複数の鉤状突起１１，１１…が形成されている。   In the above embodiment, a plurality of hook-shaped protrusions 11, 11,... Are formed in the peripheral area of the lower half area 7a of the back surface of the core member 7 at a predetermined interval as shown in FIG.

この鉤状突起１１は、図４にその一つを拡大した断面図を示すように、芯材７の外面に切り起こし状に形成されており、その突端１１ａは芯材７の下半部領域７ａの中央に向く方向に形成されていて、前記クッション材８を含む芯材７に袋状に形成された布カバー９を上方から被せ、その裾部分を芯材７の中央方向へ引張りながら前記各鉤状突起１１，１１…に引っ掛けることにより芯材７およびクッション材８に密着した緊張状態に取り付けられる。   As shown in FIG. 4, an enlarged cross-sectional view of one of the hook-shaped protrusions 11 is formed in a cut-and-raised shape on the outer surface of the core member 7, and the protruding end 11 a is a lower half region of the core member 7. The cloth cover 9 formed in a bag shape is covered with the core material 7 including the cushion material 8 from above, and the hem portion is pulled in the center direction of the core material 7. It is attached to the tension | tightness state closely_contact | adhered to the core material 7 and the cushion material 8 by hooking on each hook-shaped protrusion 11,11 ....

前記芯材７の下半部領域７ａに相当する外面で前記したフレーム１０の上部に至る範囲には樹脂製の化粧カバー１２がネジ止めあるいは嵌め込み等により取り付けられ、この化粧カバー１２と芯材７により前記鉤状突起１１，１１…による係着部分が隠蔽されるとともに化粧カバー１２の上縁のエッジ部と芯材７で布カバー９が押圧され、布カバー９に緊張が与えられてしわ切りがなされ、布カバー９の形態が整えられる。   A resin-made decorative cover 12 is attached to the outer surface corresponding to the lower half region 7a of the core material 7 to the upper portion of the frame 10 by screwing or fitting, and the decorative cover 12 and the core material 7 are attached. , The engaging portion formed by the hook-shaped projections 11, 11... Is concealed and the cloth cover 9 is pressed by the edge portion of the upper edge of the decorative cover 12 and the core material 7, and tension is applied to the cloth cover 9 to crease it. And the shape of the cloth cover 9 is adjusted.

したがってこの実施形態によれば、布カバー９の取り付け時には布カバー９の布地の下方部の複数箇所をそれぞれ鉤状突起１１，１１…に引っ掛けるだけで固定することができ、布地に緊張を与えての被着を容易に行うことができる。   Therefore, according to this embodiment, when the cloth cover 9 is attached, a plurality of portions at the lower part of the cloth of the cloth cover 9 can be fixed by simply hooking them on the hook-shaped protrusions 11, 11. Can be easily applied.

また布カバー９の交換時（廃棄時）における取り外しには、布カバー９の布地を鉤状突起１１，１１…から抜き外すだけで芯材７から分離することができるので解体作業が容易であり、分離後は布カバー９に異種材質の部材が全く付帯していないので、そのまま廃棄処理することができ、分別廃棄の手数も全く要することがない。   In addition, when the cloth cover 9 is replaced (discarded), the cloth cover 9 can be separated from the core material 7 by simply removing the cloth cover 9 from the hook-shaped protrusions 11, 11. After the separation, the cloth cover 9 is not attached with any member of a different material, so that it can be disposed of as it is, and there is no need for separation and disposal.

前記鉤状突起１１，１１…と対応する位置の布カバー９に図７にその一つを示すように予め孔１３を設けておき、この孔１３を鉤状突起１１，１１…に嵌めることにより取り付けるようにしてもよい。この場合には、鉤状突起１１の先端は必ずしも鋭利に形成せずともよい。   As shown in FIG. 7, a hole 13 is provided in advance in the cloth cover 9 at a position corresponding to the hook-shaped protrusions 11, 11,... And the hole 13 is fitted into the hook-shaped protrusions 11, 11,. You may make it attach. In this case, the tip of the hook-shaped protrusion 11 does not necessarily have to be formed sharply.

他の構成は、前述の実施形態と全く同様であり、化粧カバー１２により鉤状突起１１，１１…による係着部分を隠蔽して外部から鉤状突起１１，１１…や孔１３を全く見えなくし、外観を整えることができる。   Other configurations are exactly the same as those of the above-described embodiment, and the decorative cover 12 hides the engaging portions of the hook-shaped protrusions 11, 11,... So that the hook-shaped protrusions 11, 11,. The appearance can be trimmed.

図８、図９は本発明の他の実施形態を示すもので、この実施形態では前記実施形態における化粧カバー１２を用いず、背もたれ６の下端フレーム１０の上部位置まで布カバー９が現れる形態とする場合である。   FIGS. 8 and 9 show another embodiment of the present invention. In this embodiment, the cloth cover 9 appears up to the upper position of the lower end frame 10 of the backrest 6 without using the decorative cover 12 in the above embodiment. This is the case.

すなわち図９に部分拡大断面図を示すように、布カバー９の下端部が糸１５ａによって縫着されて筒状部１５が形成され、側面視鋭角に屈曲形成された略Ｌ字状をなす樹脂製の鉤状片１４が筒状部１５に挿入される。この鉤状片１４の立ち上がり片１４ａが、前記芯材７と実質的に一体で芯材７の下端背面よりやや引込んだ位置に設けられているアルミ製の下フレーム１０に形成されている孔１６に下から引掛けるように挿入することにより布カバー９の下端が固定されるようになっている。   That is, as shown in a partially enlarged cross-sectional view in FIG. 9, a substantially L-shaped resin in which the lower end portion of the cloth cover 9 is sewn with a thread 15 a to form a cylindrical portion 15 and is bent at an acute angle in side view. The made cage-shaped piece 14 is inserted into the cylindrical portion 15. A hole formed in the aluminum lower frame 10 in which the rising piece 14a of the bowl-shaped piece 14 is substantially integrated with the core member 7 and is provided at a position slightly retracted from the back of the lower end of the core member 7. The lower end of the cloth cover 9 is fixed by being inserted so as to be hooked on 16 from below.

そしてこの鉤状片１４による係着部分を覆うように断面逆台形状に折曲形成された樹脂製の下カバー１７が下フレーム１０の下面側から嵌め込まれてネジ止めされ、この下カバー１７のエッジ部１７ａで布カバー９が押圧されて緊張が与えられるとともにしわ切りされるようになっている。   Then, a resin lower cover 17 bent in an inverted trapezoidal cross section so as to cover the engagement portion by the bowl-shaped piece 14 is fitted from the lower surface side of the lower frame 10 and screwed. The cloth cover 9 is pressed by the edge portion 17a to give tension and to be wrinkled.

この実施形態によれば、鉤状片１４を下フレーム１０の孔１６に差し込むだけで布カバー９の取り付けができ、また取り外し時には下カバー１７を外したのち鉤状片１４を下フレーム１０の孔１６から抜くだけでよく、さらに布カバー９の廃棄時には鉤状片１４を筒状部１５から抜くだけで筒状部１５を布カバー９から分離させることができるので分別処理にも多くの手数を要することなく行うことができる。また鉤状片１４による係着部分は下カバー１７で覆われるので、外部には全く現れることがなく、椅子としてのデザインを損なうことがない。   According to this embodiment, the cloth cover 9 can be attached simply by inserting the hook-like piece 14 into the hole 16 of the lower frame 10, and when removing, the lower cover 17 is removed and the hook-like piece 14 is then attached to the hole of the lower frame 10. 16 can be separated from the cloth cover 9 by simply removing the bowl-shaped piece 14 from the tubular part 15 when the cloth cover 9 is discarded. It can be done without need. Moreover, since the engaging part by the hook-shaped piece 14 is covered with the lower cover 17, it does not appear outside at all, and the design as a chair is not impaired.

図１０は前記鉤状片１４に代えピン１８を用いて布カバー９を取り付けるようにした実施形態を示すもので、前記図９に相当する図として示している。   FIG. 10 shows an embodiment in which the cloth cover 9 is attached using a pin 18 instead of the hook-shaped piece 14, and is shown as a view corresponding to FIG.

すなわち布カバー９を下フレーム１０の孔１９にピン１８により圧入することで布カバー９を下フレーム１０に固定するようにしたものである。他は図９と同様であるからこれと同一部材には同一符号を付すに留める。   That is, the cloth cover 9 is fixed to the lower frame 10 by press-fitting the cloth cover 9 into the hole 19 of the lower frame 10 with the pins 18. The other parts are the same as those in FIG. 9, and therefore, the same members are designated by the same reference numerals.

したがってこの実施形態によれば、布カバー９を下方に引張ってピン１８を布カバー９の布地と共に下フレーム１０の孔１９に圧入するだけで布カバー９を緊張状態に張ることができ、布カバー９の取り外し時には布カバー９ごと下フレーム１０に対し下方へ引張ればピン１８ごと外れ、そのピン１８を布カバー９から引き抜けば分別廃棄ができる。   Therefore, according to this embodiment, the cloth cover 9 can be tensioned only by pulling the cloth cover 9 downward and press-fitting the pin 18 together with the cloth of the cloth cover 9 into the hole 19 of the lower frame 10. When detaching 9, the cloth cover 9 is pulled downward with respect to the lower frame 10 together with the pin 18, and the pin 18 is pulled out of the cloth cover 9 to be separated and discarded.
