Description

Translated fromJapanese

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 simply by 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 toclaim 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: apedestal 3 supported on apedestal 2 standing on aleg 1 with casters so that the height can be adjusted and rotated; Theback frame 4 is a risingportion 4 a that rises upward, theseat portion 5 that is installed on thecradle 3, and thebackrest 6 that is supported by the risingportion 4 a of theback 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。  Thebackrest 6 is provided integrally with the raisedportion 4a of theback 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 thecore material 7. Acushion material 8 made of an elastic material such as urethane foam, and acloth cover 9 formed in a bag shape including thecushion material 8 from above thecore material 7, An aluminumlower frame 10 which is substantially integrated with theback 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 thecore 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 thecore member 7, and the protrudingend 11 a is a lower half region of thecore member 7. Thecloth cover 9 formed in a bag shape is covered with thecore material 7 including thecushion material 8 from above, and the hem portion is pulled in the center direction of thecore material 7. It is attached to the tension | tightness state closely_contact | adhered to thecore material 7 and thecushion 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-madedecorative cover 12 is attached to the outer surface corresponding to the lower half region 7a of thecore material 7 to the upper portion of theframe 10 by screwing or fitting, and thedecorative cover 12 and thecore material 7 are attached. , The engaging portion formed by the hook-shaped projections 11, 11... Is concealed and thecloth cover 9 is pressed by the edge portion of the upper edge of thedecorative cover 12 and thecore material 7, and tension is applied to thecloth cover 9 to cut out the wrinkles. And the shape of thecloth 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 thecloth cover 9 is attached, a plurality of portions at the lower part of the cloth of thecloth 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 thecloth cover 9 is replaced (discarded), thecloth cover 9 can be separated from thecore material 7 by simply removing thecloth cover 9 from the hook-shaped protrusions 11, 11. After the separation, thecloth 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, ahole 13 is provided in advance in thecloth cover 9 at a position corresponding to the hook-shaped protrusions 11, 11,... And thehole 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 thedecorative 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, thecloth cover 9 appears up to the upper position of thelower end frame 10 of thebackrest 6 without using thedecorative 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 thecloth cover 9 is sewn with a thread 15 a to form acylindrical portion 15 and is bent at an acute angle in side view. The made cage-shaped piece 14 is inserted into thecylindrical portion 15. A hole formed in the aluminumlower frame 10 in which the rising piece 14a of the bowl-shaped piece 14 is substantially integrated with thecore member 7 and is provided at a position slightly retracted from the back of the lower end of thecore member 7. The lower end of thecloth 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 resinlower cover 17 bent in an inverted trapezoidal cross section so as to cover the engagement portion by the bowl-shapedpiece 14 is fitted from the lower surface side of thelower frame 10 and screwed. Thecloth 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, thecloth cover 9 can be attached simply by inserting the hook-like piece 14 into thehole 16 of thelower frame 10, and when removing, thelower cover 17 is removed and the hook-like piece 14 is then attached to the hole of thelower frame 10. 16 can be separated from thecloth cover 9 by simply removing the bowl-shapedpiece 14 from thetubular part 15 when thecloth cover 9 is discarded. It can be done without need. Moreover, since the engaging part by the hook-shapedpiece 14 is covered with thelower 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 thecloth cover 9 is attached using apin 18 instead of the hook-shapedpiece 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, thecloth cover 9 is fixed to thelower frame 10 by press-fitting thecloth cover 9 into thehole 19 of thelower frame 10 with thepins 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, thecloth cover 9 can be tensioned only by pulling thecloth cover 9 downward and press-fitting thepin 18 together with the cloth of thecloth cover 9 into thehole 19 of thelower frame 10. When detaching 9, thecloth cover 9 is pulled downward with respect to thelower frame 10 together with thepin 18, and thepin 18 is pulled out of thecloth cover 9 to be separated and discarded.
