Description

本発明は、椅子、特に座と座支持体とをネジを用いて相互に固定した椅子に関するものである。   The present invention relates to a chair, particularly a chair in which a seat and a seat support are fixed to each other using screws.

従来より、座と、当該座を支持する座支持体とをネジを用いて相互に固定した椅子が知られている。具体的には、座の裏面に周辺部位よりも窪ませた凹部を設け、この凹部に、座支持体に設けた例えば舌片状の締結部を収容させた状態で、凹部に設けたネジ孔にネジを締結部とともに締め付けることにより、座支持体を座の裏面に締着させた態様が知られている。そして、ネジや締結部が露出することを防止するために、凹部を被覆するキャップ部材を座の裏面に取り付けるようにしている。   Conventionally, a chair is known in which a seat and a seat support that supports the seat are fixed to each other using screws. Specifically, a recessed portion recessed from the peripheral portion is provided on the back surface of the seat, and a screw hole provided in the recessed portion is accommodated in this recessed portion, for example, a tongue-shaped fastening portion provided on the seat support body. There is known a mode in which the seat support is fastened to the back surface of the seat by fastening the screw together with the fastening portion. And in order to prevent that a screw and a fastening part are exposed, the cap member which coat | covers a recessed part is attached to the back surface of a seat.

なお、上述したような従来技術は、現場において適宜実施されるものであり、特許文献などとして開示されているものはない。   Note that the above-described conventional techniques are appropriately implemented in the field, and none are disclosed as patent documents.

ところで、座支持体と座との締着箇所を増加するため、或いは座に種々の機能を付与するために、座の裏面における所定領域に複数の凹部を集合させて設ける態様も考えられる。   By the way, in order to increase the fastening location between the seat support and the seat, or to give various functions to the seat, a mode in which a plurality of concave portions are provided in a predetermined region on the back surface of the seat is also conceivable.

このような態様を採用した場合、これら各凹部を共通のキャップ部材で被覆することができれば、各凹部をそれぞれ別々のキャップ部材で被覆する場合と比較して、座にキャップ部材を取り付ける手間を軽減することができる。   When such an aspect is adopted, if these recesses can be covered with a common cap member, the labor for attaching the cap member to the seat can be reduced as compared with the case where each recess is covered with a separate cap member. can do.

一方で、座の裏面に座支持体を締着した後に、各凹部を共通のキャップ部材で被覆する態様とすれば、キャップ部材を、座支持体を迂回する形状としなければならず、単純な略平板状のものとすることができないという不具合が生じる。   On the other hand, if the recess is covered with a common cap member after the seat support is fastened to the back surface of the seat, the cap member must have a shape that bypasses the seat support, and is simple. The problem that it cannot be made into a substantially flat thing arises.

他方、キャップ部材を単純な略平板状のものとした場合には、座支持体との干渉を避けるために、座支持体の締結部を凹部に収容する前段階でキャップ部材を座の裏面に取り付ける必要がある。しかしながら、座支持体の締結部を凹部に収容する前段階で単純な平板状のキャップ部材を座の裏面に取り付けた場合には、凹部が全て被覆されるため、締結部を凹部に収容することができず、座と座支持体とを締着することができないという致命的な不具合が生じる。   On the other hand, when the cap member is a simple substantially flat plate, in order to avoid interference with the seat support, the cap member is placed on the back surface of the seat before the fastening portion of the seat support is received in the recess. It is necessary to install. However, when a simple flat cap member is attached to the back surface of the seat before the fastening portion of the seat support is received in the recess, all the recesses are covered, so that the fastening portion is stored in the recess. A fatal problem that the seat and the seat support cannot be fastened.

そこで、単純な平板状のキャップ部材に、一の凹部に収容可能な被収容部を設け、さらにこの被収容部にネジが挿通可能な挿通孔を形成し、この被収容部を凹部に収容した後に、当該凹部に座支持体の締結部を収容し、この状態で締結部側からネジを締め付けることにより座支持体と座とを締着する態様も考えられる。   Therefore, a simple flat cap member is provided with a receiving portion that can be stored in one recess, and further, an insertion hole through which a screw can be inserted is formed in the receiving portion, and the receiving portion is stored in the recess. It is also conceivable that the seat support is fastened to the seat by accommodating the fastening portion of the seat support in the recess and tightening the screw from the fastening portion side in this state.

しかしながら、座の凹部と座支持体の締結部との間にキャップ部材の被収容部が介在する態様となるため、この状態で締め付け作業を行った場合、被収容部が樹脂製のものであればネジの緩みを招来し得るものとなり、強固な締付状態を維持できないという問題が生じる。   However, since the accommodated portion of the cap member is interposed between the recessed portion of the seat and the fastening portion of the seat support, if the tightening operation is performed in this state, the accommodated portion is made of resin. If this occurs, the screw may be loosened, resulting in a problem that a strong tightening state cannot be maintained.

本発明は、このような課題に着目してなされたものであって、主たる目的は、座の裏面に集合させて形成した複数の凹部を共通のキャップ部材によって全て被覆することができるとともに、ネジの締め付け作業を好適に行うことができ、さらには締付強度にも悪影響を及ぼすことのない椅子を提供することにある。   The present invention has been made paying attention to such a problem, and the main object is to cover all of the plurality of concave portions formed on the back surface of the seat with a common cap member, and screw. It is an object of the present invention to provide a chair that can suitably perform the tightening operation and does not adversely affect the tightening strength.

すなわち、本発明の椅子は、裏面からアクセス可能なネジ孔を有する座と、前記座の裏面にネジを用いて締着される締結部を有する座支持体と、前記ネジ及び前記締結部を下方から被覆し得るキャップ部材とを備えたものであって、前記座が、裏面の所定領域に複数の凹部を集合させて設け、前記ネジ孔を有する少なくとも一の凹部に前記締結部を収容し得るものであり、前記キャップ部材が、前記複数の凹部をそれぞれ被覆し得る複数の被覆部を有するものであり、これら複数の被覆部のうち前記締結部が収容される凹部、すなわちネジが螺合可能なネジ孔を有する凹部を被覆し得る被覆部を、当該凹部を露出させ得る窓部と、当該窓部を開閉し得る開閉部とを用いて構成していることを特徴とする。   That is, the chair of the present invention includes a seat having a screw hole accessible from the back surface, a seat support having a fastening portion fastened with a screw to the back surface of the seat, and the screw and the fastening portion downward. A cap member that can be coated from a plurality of recesses in a predetermined region on the back surface, and the fastening portion can be accommodated in at least one recess having the screw hole. The cap member has a plurality of covering portions that can respectively cover the plurality of recessed portions, and a recessed portion in which the fastening portion is accommodated among the plurality of covering portions, that is, a screw can be screwed. The covering portion that can cover the concave portion having a screw hole is configured using a window portion that can expose the concave portion and an opening and closing portion that can open and close the window portion.

このようなものであれば、座の裏面にキャップ部材を取り付けた後、開放された窓部を介して締結部を凹部に収容することができ、この収容状態で、開放された窓部を介してネジ孔にアクセス可能となるため、このネジ孔にネジを螺合することによって締着部を座の裏面に締着することができ、従来の不具合、すなわちネジの締着作業前にキャップ部材を取り付けた場合に、ネジ孔にアクセスすることができず、締着作業そのものができないという不具合を解消することができる。しかも、座の裏面に形成した複数の凹部をキャップ部材の各被覆部によって全て被覆することができ、各凹部をそれぞれ別体のキャップ部材で被覆する態様と比較して、各凹部を被覆する作業の効率が向上する。加えて、締付作業後には開閉部によって窓部を閉止することにより凹部内に存在するネジ及び締結部を好適に被覆することができ、良好な外観を呈するものとなる。   If it is such, after attaching a cap member to the back of a seat, a fastening part can be stored in a crevice via an opened window part, and in this accommodation state via an opened window part Since the screw hole can be accessed, the fastening portion can be fastened to the back surface of the seat by screwing the screw into the screw hole. When the is attached, the problem that the screw hole cannot be accessed and the fastening operation itself cannot be performed can be solved. In addition, the plurality of recesses formed on the back surface of the seat can be all covered with the respective cover portions of the cap member, and the operation of covering each recess as compared with the embodiment in which each recess is covered with a separate cap member. Increases efficiency. In addition, after the tightening operation, by closing the window portion with the opening / closing portion, the screw and the fastening portion existing in the recess can be suitably covered, and a good appearance is exhibited.

特に、前記キャップ部材が、前記複数の被覆部を一体に有する樹脂成型品であれば、キャップ部材が各被覆部を相互に接続部材を介して接続したものである態様と比較して、各被覆部を相互に接続する手間を省略することができ、また製造時点における部品点数の削減を図ることができ、座に対するキャップ部材の取付作業の簡素化に資する。   In particular, if the cap member is a resin molded product that integrally includes the plurality of covering portions, each cap member is compared with an embodiment in which the cap members are connected to each other via a connecting member. The trouble of connecting the parts to each other can be omitted, and the number of parts at the time of manufacture can be reduced, which contributes to simplification of the work of attaching the cap member to the seat.

また、前記締結部が金属製のものであれば、締結部が樹脂製であれば生じ得る不具合、すなわちネジの締め付け作業によって締結部自体が押し潰されて変形するという不具合を解消し、強固な締着状態を実現できる。   Further, if the fastening part is made of metal, the problem that may occur if the fastening part is made of resin, that is, the problem that the fastening part itself is crushed and deformed by the tightening operation of the screw is eliminated, and the Fastened state can be realized.

開閉部の開閉動作を直感的に把握できるようにし、開閉作業を簡単に行うことができるようにするには、前記開閉部を、前記窓部との接続部位に設けたヒンジ部を軸に、前記窓部を開放する開放位置と、前記窓部を閉止し得る閉止位置との間で回動可能なものとすればよい。   In order to make it possible to intuitively grasp the opening and closing operation of the opening and closing part, and to be able to easily perform the opening and closing operation, the opening and closing part, with the hinge part provided at the connection part with the window part as an axis, What is necessary is just to be able to rotate between the open position which opens the said window part, and the closed position which can close the said window part.

座支持体の好適な実施態様としては、前記座の裏面に配される金属製のフレーム本体と、当該フレーム本体に溶着によって接合した前記締結部とを備えた態様が挙げられる。このようなものであれば、フレーム本体と締結部との取付強度の向上を図ることができるとともに、フレーム本体と締結部とをビス止めによって取り付ける態様と比較してフレーム本体と締結部との組付作業を容易に行うことができる。   As a preferred embodiment of the seat support, there may be mentioned an embodiment provided with a metal frame main body disposed on the back surface of the seat and the fastening portion joined to the frame main body by welding. If it is such, while improving the attachment strength of a frame main body and a fastening part, compared with the aspect which attaches a frame main body and a fastening part by screwing, it is a group of a frame main body and a fastening part. Attaching work can be easily performed.

加えて、前記キャップ部材が、前記窓部に連続して開口する開口部を備えたものであり、少なくとも前記フレーム本体と前記締結部との接合部分を開口部に配することによって前記開閉部と当該接合部分との干渉を回避し得るようにすれば、窓部を閉止した開閉部と締結部とが相互に干渉することなく、当該開閉部による良好な被覆状態を実現できる。   In addition, the cap member is provided with an opening that opens continuously to the window, and at least a joint portion between the frame main body and the fastening portion is disposed in the opening. If interference with the joint portion can be avoided, a good covering state by the opening / closing portion can be realized without the opening / closing portion closing the window portion and the fastening portion interfering with each other.

以上説明したように本発明によれば、座の裏面に集合させて形成した複数の凹部を共通のキャップ部材によって全て被覆することができるとともに、ネジの締め付け作業を好適に行うことができ、さらには締付強度にも悪影響を及ぼすことのない椅子を提供することができる。   As described above, according to the present invention, it is possible to cover all the plurality of recesses formed by being assembled on the back surface of the seat with a common cap member, and it is possible to suitably perform a screw tightening operation, Can provide a chair that does not adversely affect the tightening strength.

While abutting or approaching the standing wall portion via the protrusion 6 d, the outer edge portion of the third covering portion main body 631 hits the abutting step portion 223 a of the third recess 223.

そして、図２に示すように、開閉部６１２を開放位置（Ｘ）に位置付けることにより、凹部集合領域２２Ａのうち第１凹部２２１が窓部６１１を介して開放される。なお、予め開閉部６１２を開放位置（Ｘ）に位置付けたキャップ部材６を凹部集合領域２２Ａに取り付ける態様、或いは閉止位置（Ｙ）に位置付けた開閉部６１２を凹部集合領域２２Ａに取り付けた後に開閉部６１２を開放位置（Ｘ）に位置付ける態様、何れの態様であっても構わない。なお、本実施形態では、左右一対のキャップ部材６として、左右一対の凹部集合領域２２Ａの形状に対応させて、互いに対称形状をなすものを適用している。   Then, as shown in FIG. 2, by positioning the opening / closing part 612 at the open position (X), the first recessed part 221 in the recessed part collecting area 22 </ b> A is opened through the window part 611. Note that the cap member 6 in which the opening / closing portion 612 is positioned in the open position (X) in advance is attached to the recessed portion collecting region 22A, or the opening / closing portion after the opening / closing portion 612 positioned in the closed position (Y) is attached to the recessed portion collecting region 22A. A mode in which 612 is positioned at the open position (X) or any mode may be used. In the present embodiment, the pair of left and right cap members 6 that are symmetrical to each other are applied in correspondence with the shape of the pair of left and right recessed portion collecting regions 22A.

次いで、キャップ部材６を取り付けた座シェル２２の裏面に、座支持体３の当接フレーム３２を当てるようにして取り付ける。この際、当接フレーム３２の各締結部３２２を、それぞれ各凹部集合領域２２Ａのうち窓部６１１を介して開放された第１凹部２２１に収容する。この収容状態において、当接フレーム３２のフレーム本体３２１が、底面視において各凹部集合領域２２Ａの第１凹部２２１と第２凹部２２２とを分断し得る位置、換言すればキャップ部材６の第１被覆部６１と第２被覆部６２とを分断し得る位置に配される。またフレーム本体３２１が、各凹部集合領域２２Ａ間、換言すれば各キャップ部材６間を跨ぐ位置に配される。   Next, it is attached so that the contact frame 32 of the seat support 3 is applied to the back surface of the seat shell 22 to which the cap member 6 is attached. At this time, the respective fastening portions 322 of the contact frame 32 are accommodated in the first concave portions 221 opened via the window portions 611 in the respective concave portion collecting regions 22A. In this accommodated state, the frame body 321 of the abutting frame 32 can divide the first concave portion 221 and the second concave portion 222 of each concave portion collecting region 22A in bottom view, in other words, the first covering of the cap member 6. It arrange | positions in the position which can divide the part 61 and the 2nd coating | coated part 62. FIG. Further, the frame main body 321 is disposed at a position straddling between the respective recessed portion collecting regions 22A, in other words, between the respective cap members 6.

当接フレーム３２の各締結部３２２をそれぞれ第１凹部２２１に収容することにより、締結部３２２の締結部本体３２２ａが、第１凹部２２１の第１底壁部２２１ａに当接するとともに、第１底壁部２２１ａに形成したナット連通孔２２１ｂを介してナットＮと締結部本体３２２ａの貫通孔３２２ｄとが相互に連通した状態となる。この状態において、締結部３２２側から貫通孔３２２ｄ、ナット連通孔２２１ｂの順に挿入したネジＳをナットＮに螺合させる。そしてネジＳをナットＮに締め付けることにより、スチール製の締結部本体３２２ａが第１凹部２２１の第１底壁部２２１ａに圧接し、座シェル２２と座支持体３とが強固に固定される（図２参照）。   By accommodating each fastening portion 322 of the contact frame 32 in the first recess 221, the fastening portion main body 322 a of the fastening portion 322 contacts the first bottom wall portion 221 a of the first recess 221 and the first bottom The nut N and the through hole 322d of the fastening portion main body 322a are in communication with each other through the nut communication hole 221b formed in the wall portion 221a. In this state, the screw S inserted in order of the through hole 322d and the nut communication hole 221b from the fastening portion 322 side is screwed into the nut N. Then, by tightening the screw S to the nut N, the steel fastening portion main body 322a comes into pressure contact with the first bottom wall portion 221a of the first recess 221, and the seat shell 22 and the seat support 3 are firmly fixed ( (See FIG. 2).

最後に、図６に示すように、開放位置（Ｘ）にある開閉部６１２を閉止位置（Ｙ）に位置付けることによって、第１凹部２２１、ネジＳ、及び締結部３２２の締結部本体３２２ａを被覆する。この際、開閉部６１２に設けた回避部６１２ｂにより開閉部６１２とネジＳとの干渉を防止している。また、開閉部６１２を開放位置（Ｘ）から閉止位置（Ｙ）に移動させる過程で、開閉部６１２の係止爪６１２ａが第２被覆部本体６２１の縁部に当たるが、さらに開閉部６１２を閉止位置（Ｙ）に向かって押圧することによって係止爪６１２ａが弾性変形しながら第２被覆部本体６２１を乗り越え、当該乗り越えた時点で係止爪６１２ａが第２被覆部本体６２１に設けた被係合部６３２に係合する。   Finally, as shown in FIG. 6, the first recess 221, the screw S, and the fastening part main body 322 a of the fastening part 322 are covered by positioning the opening / closing part 612 in the open position (X) at the closing position (Y). To do. At this time, interference between the opening / closing portion 612 and the screw S is prevented by an avoidance portion 612b provided in the opening / closing portion 612. Further, in the process of moving the opening / closing part 612 from the open position (X) to the closing position (Y), the locking claw 612a of the opening / closing part 612 hits the edge of the second covering part main body 621, but the opening / closing part 612 is further closed. When the locking claw 612a is elastically deformed by pressing toward the position (Y), it gets over the second covering portion main body 621, and when it gets over, the engaging claw 612a is provided on the second covering portion main body 621. Engage with the mating part 632.

なお、開閉部６１２を閉止位置（Ｙ）に位置付けた状態において、当該開閉部６１２が、フレーム本体３２１と締結部３２２との接合部分（具体的にはフレーム本体３２１と締結部本体３２２ａとの接合部分、すなわち締結部３２２のうち立ち上がり部３２２ｃに相当する部分）に干渉することを回避するために、各キャップ部材６に、窓部６１１に連続して開口する開口部６４を形成している（図５及び図６参照）。当該開口部６４は、開閉部６１２を閉止位置（Ｙ）に位置付けた場合であっても開閉部６１２によって閉止されることなく、常時開放されたものとなる。   In the state where the opening / closing part 612 is positioned at the closed position (Y), the opening / closing part 612 is connected to the joint portion between the frame main body 321 and the fastening portion 322 (specifically, the joint between the frame main body 321 and the fastening portion main body 322a). In order to avoid interfering with the portion, that is, the portion corresponding to the rising portion 322c of the fastening portion 322, each cap member 6 is formed with an opening portion 64 that opens continuously to the window portion 611 ( (See FIGS. 5 and 6). The opening 64 is always opened without being closed by the opening / closing part 612 even when the opening / closing part 612 is positioned at the closing position (Y).

このように、本実施形態に係る椅子１は、座２の裏面に集合配置された被覆すべき複数の凹部２２１、２２２、２２３を、キャップ部材６の各被覆部６１、６２、６３によって全て被覆することができるとともに、開放された窓部６１１を介して締結部３２２を第１凹部２２１に収容した状態で、この第１凹部２２１に設けたナットＮに座２の裏面側からアクセス可能な状態となるため、このナットＮにネジＳを螺合させて締結部３２２を第１凹部２２１に締着することによって座２と座支持体３との固定作業を好適に行うことができる。しかも、締着作業後には開閉部６１２によって窓部６１１を閉止することによりネジＳ及び締結部３２２を被覆することができ、良好な外観を呈するものとなる。   Thus, the chair 1 according to the present embodiment covers all of the plurality of recesses 221, 222, and 223 that are collectively arranged on the back surface of the seat 2 with the covering portions 61, 62, and 63 of the cap member 6. In a state where the fastening portion 322 is accommodated in the first recess 221 through the opened window 611, the nut N provided in the first recess 221 is accessible from the back side of the seat 2 Therefore, the fixing operation of the seat 2 and the seat support 3 can be suitably performed by screwing the screw S into the nut N and fastening the fastening portion 322 to the first recess 221. In addition, the screw S and the fastening portion 322 can be covered by closing the window portion 611 with the opening / closing portion 612 after the fastening operation, and a good appearance is exhibited.

特に、キャップ部材６が、複数の被覆部２２１、２２２、２２３を一体に有する樹脂成型品であるため、部品点数の削減、及び取り扱い易さの向上に資するものとなり、ひいては座３の裏面にキャップ部材６を取り付ける作業の簡素化をも図ることができる。   In particular, since the cap member 6 is a resin molded product integrally having a plurality of covering portions 221, 222, and 223, it contributes to a reduction in the number of parts and an improvement in handling ease. The work of attaching the member 6 can also be simplified.

さらに、締結部３２２が金属製のものであるため、締結部３２２が樹脂製であれば生じ得る不具合、すなわちネジＳの締め付け作業によって締結部３２２自体が押し潰されて変形するという不具合を解消し、強固な締着状態を実現できる。   Further, since the fastening part 322 is made of metal, the problem that may occur if the fastening part 322 is made of resin, that is, the problem that the fastening part 322 itself is crushed and deformed by the tightening operation of the screw S is solved. A firm fastening state can be realized.

また、開閉部６１２が、ヒンジ部６１４を軸に、窓部６１１を開放する開放位置（Ｘ）と、窓部６１１を閉止し得る閉止位置（Ｙ）との間で回動可能なものであるため、開閉部６１２の開閉動作を直感的に把握でき、開閉部６１２の開閉作業を簡単に行うことができる。   Further, the opening / closing part 612 is rotatable between an opening position (X) for opening the window part 611 and a closing position (Y) for closing the window part 611 with the hinge part 614 as an axis. Therefore, the opening / closing operation of the opening / closing unit 612 can be intuitively grasped, and the opening / closing operation of the opening / closing unit 612 can be easily performed.

加えて、座支持体３が、座２の裏面に配される金属製のフレーム本体３２１と、フレーム本体３２１に溶着によって接合した締結部３２２とを備えたものであるため、フレーム本体３２１と締結部３２２との取付強度の向上を図ることができ、有効な支持強度を発揮するものとなる。また、フレーム本体３２１と締結部３２２とをビス止めによって取り付ける態様と比較してフレーム本体３２１と締結部３２２との組付作業を容易に行うことができる。   In addition, since the seat support 3 includes a metal frame main body 321 disposed on the back surface of the seat 2 and a fastening portion 322 joined to the frame main body 321 by welding, the seat support 3 is fastened to the frame main body 321. The attachment strength with the portion 322 can be improved, and effective support strength is exhibited. Further, the assembly work of the frame main body 321 and the fastening portion 322 can be easily performed as compared with the aspect in which the frame main body 321 and the fastening portion 322 are attached by screwing.

キャップ部材６が、窓部６１１に連続して開口する開口部６４を備えたものであり、フレーム本体３２１と締結部３２２との接合部分、具体的にはフレーム本体３２１と締結部本体３２２ａとの接合部分、すなわち締結部３２２のうち立ち上がり部３２２ｃに相当する部分、を開口部６４に配することによって閉止位置（Ｙ）に位置付けた開閉部６１２が座支持体３の一部と干渉することを回避しているため、開閉部６１２と座支持体３の一部との干渉に起因する開閉部６１２の動作不良の発生を確実に防止することができる。   The cap member 6 is provided with an opening portion 64 that opens continuously to the window portion 611, and a joint portion between the frame main body 321 and the fastening portion 322, specifically, the frame main body 321 and the fastening portion main body 322a. By arranging the joint portion, that is, the portion corresponding to the rising portion 322c in the fastening portion 322 in the opening 64, the opening / closing portion 612 positioned at the closed position (Y) interferes with a part of the seat support 3. Therefore, the malfunction of the opening / closing part 612 due to the interference between the opening / closing part 612 and part of the seat support 3 can be reliably prevented.
