Description

この発明は、配線器具等の被取着物を簡単かつ確実に固定することができる、取着体およびビス固定部材に関するものである。   The present invention relates to an attachment body and a screw fixing member capable of easily and reliably fixing an object to be attached such as a wiring device.

従来、建物の壁表側から、被取着物としての配線器具を固定するには、取付け用のビスを、前記配線器具が取着された器具枠に挿通するとともに、壁内に隠蔽もしくは埋設された、取着体としての配線用ボックスの一対のボス部内に収容されたナット、または、そのボックスに取り付けられた、取着体としてのボックスカバーの一対のボス部内に収容されたナットに、前記ビスをねじ込んでいた。   Conventionally, in order to fix a wiring device as an attachment from the front side of a building wall, a mounting screw is inserted into a device frame to which the wiring device is attached and concealed or buried in the wall. The nuts accommodated in the pair of bosses of the wiring box as the attachment body, or the nuts accommodated in the pair of boss portions of the box cover as the attachment body attached to the box, Was screwed in.

しかし、前記ビスによるねじ込み作業は、ビスをドライバーで回転させて締め込んでいかなければならず、大変面倒でかつ時間のかかるものであった。   However, the screwing operation with the screw has to be tightened by rotating the screw with a screwdriver, which is very troublesome and time consuming.

そこで、ナットの替わりに板材を用いた配線用ボックス(埋込ボックス)が考案された(例えば、特許文献1参照)。この配線用ボックスにおいては、図7に示されるように、板材11は、通孔12aが明けられた前部片12と、側部片13、13と、たわみ片14、14とで、略C字状に形成されていた。そして、この板材11が、配線用ボックス10の突出片10aに、その突出片10aを囲むようにして取り付けられた。そこで、ビス15を、前部片12の通孔12aおよび突出片10aの孔10bを挿通させて、ドライバーで回転させることなく、たわみ片14、14間に押し込むことで、ビス15の山が、たわみ片14、14の先端部分に係合し、こうして、配線器具を固定することができた。   Accordingly, a wiring box (embedded box) using a plate material instead of a nut has been devised (see, for example, Patent Document 1). In this wiring box, as shown in FIG. 7, the plate member 11 is composed of a front piece 12 with side holes 12 a opened, side pieces 13 and 13, and flexible pieces 14 and 14. It was formed in a letter shape. And this board | plate material 11 was attached to the protrusion piece 10a of the box 10 for wiring so that the protrusion piece 10a might be enclosed. Therefore, by inserting the screw 15 through the through hole 12a of the front piece 12 and the hole 10b of the protruding piece 10a and pushing it between the flexible pieces 14 and 14 without rotating with a screwdriver, The flexible piece 14 was engaged with the distal end portion of the piece 14, and thus the wiring device could be fixed.

特開平7−193946JP-A-7-193946

ところで、取着体としての配線用ボックスにおいては、たわみ片には、例えば、取り付けられた配線器具に作用する、プラグを抜き差しする際の力とか、プラグが電気機器により引っ張られる力等に耐え得る強度が要求された。   By the way, in the wiring box as the attachment body, the flexible piece can withstand, for example, the force when inserting and removing the plug, the force by which the plug is pulled by an electric device, etc. acting on the attached wiring device. Strength was required.

しかし、前記従来の配線用ボックス10にあっては、略C字状の板材11が、配線用ボックス10の突出片10aを囲むようにして取り付けられていたため、板材11のたわみ片14、14と係合したビス15に、抜け方向の外力が作用した場合には、側部片13、13が外側に開くようにしてたわみ片14、14間の間隔が広がる虞があった。そして、このたわみ片14、14間の間隔の広がりにより、たわみ片14、14とビス15との係合が不十分となる虞があった。   However, in the conventional wiring box 10, since the substantially C-shaped plate material 11 is attached so as to surround the protruding piece 10 a of the wiring box 10, it engages with the flexible pieces 14 and 14 of the plate material 11. When an external force in the pulling direction is applied to the screw 15, the gap between the flexible pieces 14 and 14 may be widened so that the side pieces 13 and 13 are opened outward. Then, there is a possibility that the engagement between the flexible pieces 14 and 14 and the screw 15 becomes insufficient due to the widening of the interval between the flexible pieces 14 and 14.

この発明は、上記した従来の欠点を解決するためになされたものであり、その目的とするところは、ビスとの係合力を十分に確保して、被取着物を確実に取着することができる、取着体およびビス固定部材を提供することにある。   The present invention has been made to solve the above-described conventional drawbacks, and the object of the present invention is to secure a sufficient engagement force with a screw to securely attach an object to be attached. An object of the present invention is to provide an attachment body and a screw fixing member.

この発明に係る取着体およびビス固定部材は、前記目的を達成するために、次の構成からなる。すなわち、
請求項1に記載の発明に係る取着体は、配線器具等の被取着物が、ビスを用いて取着される取着体であって、少なくとも一方に開放部を有する内部空間を形成するようにその内部空間を囲む周壁と、前記周壁の内面側に位置するボス部とを備える。ここにおいて、前記ボス部は、前記ビスが前記開放部側から挿入される挿入孔と、その挿入孔と連通する収容空間とを有する。そして、前記収容空間には、前記挿入孔に挿入された前記ビスを固定するためのビス固定部材が収容される。このビス固定部材は、板材からなる。そして、このビス固定部材は、前記収容空間の向かい合う側壁面に、板面が面するようにして近接あるいは当接する一対の脚片と、それら脚片の、前記挿入孔の軸心方向の一方の端から折れ曲がって、前記挿入孔側に向かって延設され、先端が、前記挿入孔に挿入された前記ビスのビス軸部に係合する一対の弾性係合片と、前記一対の脚片を連結する連結片とを備える。そこで、前記挿入孔への前記ビス軸部の挿入に対しては、前記弾性係合片は、前記ビス軸部の挿入方向へ傾斜するように、あるいは、前記挿入方向への傾斜が増すように弾性変形することで、前記ビス軸部の、前記挿入方向への移動を許容し、前記挿入孔からの前記ビス軸部の抜けに対しては、前記ビス軸部と係合した前記弾性係合片が、前記ビス軸部の抜け方向へ、前記挿入方向への傾斜が減ずるように弾性変形しようとして、前記ビス軸部を押圧することにより、前記弾性係合片の、前記抜け方向への弾性変形を困難にして、前記ビス軸部の、前記抜け方向への移動を阻止する。
In order to achieve the above object, the attachment body and screw fixing member according to the present invention have the following configuration. That is,
The attachment body according to the first aspect of the present invention is an attachment body in which an object to be attached such as a wiring device is attached using a screw, and forms an internal space having an open portion at least on one side. As described above, a peripheral wall surrounding the internal space and a boss portion located on the inner surface side of the peripheral wall are provided. Here, the boss part has an insertion hole into which the screw is inserted from the open part side, and an accommodation space communicating with the insertion hole. A screw fixing member for fixing the screw inserted into the insertion hole is accommodated in the accommodation space. The screw fixing member is made of a plate material. The screw fixing member includes a pair of leg pieces that come close to or abut against each other on the side wall surfaces of the housing space facing the plate surface, and one of the leg pieces in the axial direction of the insertion hole. A pair of elastic engagement pieces that are bent from the ends and extend toward the insertion hole side, and whose front ends engage with the screw shaft portions of the screws inserted into the insertion holes, and the pair of leg pieces. And a connecting piece to be connected. Therefore, for the insertion of the screw shaft portion into the insertion hole, the elastic engagement piece is inclined in the insertion direction of the screw shaft portion, or the inclination in the insertion direction is increased. By elastically deforming, the screw shaft portion is allowed to move in the insertion direction, and the elastic engagement engaged with the screw shaft portion is prevented from coming off from the insertion hole. The piece is elastically deformed in the removal direction of the elastic engagement piece by pressing the screw shaft portion so as to be elastically deformed so that the inclination in the insertion direction is reduced in the removal direction of the screw shaft portion. Deformation is difficult to prevent the screw shaft portion from moving in the pulling direction.

これにより、この取着体に配線器具等の被取着物を取り付けるには、この取着体のボス部に設けられた挿入孔に、開放部側からビスを押し込むように押圧する。こうすることで、ビス固定部材に設けられた弾性係合片の先端部分が、ビス軸部に押圧される。それに共なって、弾性係合片が、ビス軸部の挿入方向へ傾斜するように、あるいは、挿入方向への傾斜が増すように弾性変形して、ビス軸部の、挿入方向への移動が許容されて、このビス軸部は、挿入孔に挿入される。そして、ビスの押し込みを終えると、弾性係合片の先端は、ビス軸部と係合し、こうして、ビスが固定され、被取着物は、取着体に取着される。ここにおいて、挿入孔からのビス軸部の抜けに対しては、ビス軸部と係合した弾性係合片が、ビス軸部につられて、その抜け方向へ、すなわち前記挿入方向への傾斜が減ずる方向へ弾性変形しようとして、弾性係合片は、ビス軸部を押圧する。そして、この押圧により、弾性係合片は、前記抜け方向への弾性変形が困難となるとともに、ビス軸部への係合が強固なものとなり、ビスの抜けが阻止される。ここで、ビス固定部材は、一対の弾性係合片が延設される一対の脚片を備えており、それら脚片は、収容空間の向かい合う側壁面に、板面が面するようにして近接あるいは当接する。したがって、一対の脚片、ひいては一対の弾性係合片は、互いに離れることはなく、弾性係合片の、ビス軸部との係合力が十分に確保される。   Thereby, in order to attach an object to be attached such as a wiring tool to the attachment body, a screw is pushed into the insertion hole provided in the boss portion of the attachment body from the open portion side. By doing so, the tip end portion of the elastic engagement piece provided on the screw fixing member is pressed against the screw shaft portion. At the same time, the elastic engagement piece is elastically deformed so as to incline in the insertion direction of the screw shaft part or to increase the inclination in the insertion direction, so that the screw shaft part moves in the insertion direction. Allowed, this screw shaft portion is inserted into the insertion hole. Then, when the screw has been pushed in, the tip of the elastic engagement piece engages with the screw shaft portion, and thus the screw is fixed, and the adherend is attached to the attachment body. Here, when the screw shaft portion is removed from the insertion hole, the elastic engagement piece engaged with the screw shaft portion is attached to the screw shaft portion, and the inclination in the removal direction, that is, the insertion direction is inclined. The elastic engagement piece presses the screw shaft portion in an attempt to elastically deform in the decreasing direction. By this pressing, the elastic engagement piece becomes difficult to be elastically deformed in the removal direction, and the engagement with the screw shaft portion becomes strong, and the screw is prevented from coming off. Here, the screw fixing member is provided with a pair of leg pieces to which a pair of elastic engagement pieces are extended, and these leg pieces are close to each other so that a plate surface faces a side wall surface facing the accommodation space. Or it contacts. Therefore, the pair of leg pieces and thus the pair of elastic engagement pieces are not separated from each other, and the engagement force of the elastic engagement pieces with the screw shaft portion is sufficiently ensured.

また、請求項2に記載の発明に係る取着体は、請求項1に記載の取着体において、前記連結片は、前記弾性係合片とは縁切りされた状態で、前記一対の脚片の前記一方の端どうしを繋ぐように設けられている。   An attachment body according to a second aspect of the present invention is the attachment body according to the first aspect, wherein the connecting piece is separated from the elastic engagement piece in the state where the pair of leg pieces is provided. Are provided so as to connect the one ends.

また、請求項3に記載の発明に係る取着体は、請求項1に記載の取着体において、前記連結片は、前記一対の脚片の、前記挿入孔の軸心方向と直交する方向の端どうしを繋ぐように設けられている。   Moreover, the attachment body which concerns on invention of Claim 3 is an attachment body of Claim 1, WHEREIN: The said connection piece is the direction orthogonal to the axial center direction of the said insertion hole of a pair of said leg piece. It is provided to connect the ends of each other.

また、請求項4に記載の発明に係る取着体は、請求項2または3に記載の取着体において、前記ビス固定部材は、前記一対の弾性係合片が、前記内部空間側とその内部空間側とは反対側となる外方側とを結ぶ縦方向に直交する横方向に並ぶように、かつ、前記連結片が、前記一対の弾性係合片に対して、前記内部空間側とは反対側となる外方側に位置するように、配置される。こうして、連結片を、一対の弾性係合片に対して、内部空間側とは反対側となる外方側に位置させることで、ビスの位置、すなわち挿入孔の位置を変えることができない場合であっても、内部空間を広く取ることができる。   An attachment body according to a fourth aspect of the present invention is the attachment body according to the second or third aspect, wherein the screw fixing member includes the pair of elastic engagement pieces and the inner space side. The connecting piece is aligned with the inner space side with respect to the pair of elastic engagement pieces so as to be arranged in a lateral direction perpendicular to the longitudinal direction connecting the outer side opposite to the inner space side. Are arranged so as to be located on the opposite outer side. Thus, when the connecting piece is positioned on the outer side opposite to the inner space side with respect to the pair of elastic engaging pieces, the position of the screw, that is, the position of the insertion hole cannot be changed. Even if there is, it can take a large internal space.

また、請求項5に記載の発明に係るビス固定部材は、配線器具等の被取着物が、ビスを用いて取着される取着体の、少なくとも一方に開放部を有する内部空間を形成するようにその内部空間を囲む周壁の、内面側に位置するボス部に収容され、前記開放部側から前記ボス部の挿入孔に挿入された前記ビスを固定するためのビス固定部材である。このビス固定部材は、板材からなる。そして、このビス固定部材は、前記ボス部に前記挿入孔と連通するように設けられた収容空間の向かい合う側壁面に、板面が面するようにして近接あるいは当接する一対の脚片と、それら脚片の、前記挿入孔の軸心方向の一方の端から折れ曲がって、前記挿入孔側に向かって延設され、先端が、前記挿入孔に挿入された前記ビスのビス軸部に係合する一対の弾性係合片と、前記一対の脚片を連結する連結片とを備える。そこで、前記挿入孔への前記ビス軸部の挿入に対しては、前記弾性係合片は、前記ビス軸部の挿入方向へ傾斜するように、あるいは、前記挿入方向への傾斜が増すように弾性変形することで、前記ビス軸部の、前記挿入方向への移動を許容し、前記挿入孔からの前記ビス軸部の抜けに対しては、前記ビス軸部と係合した前記弾性係合片が、前記ビス軸部の抜け方向へ、前記挿入方向への傾斜が減ずるように弾性変形しようとして、前記ビス軸部を押圧することにより、前記弾性係合片の、前記抜け方向への弾性変形を困難にして、前記ビス軸部の、前記抜け方向への移動を阻止する。   In addition, the screw fixing member according to the invention of claim 5 forms an internal space in which an object to be attached such as a wiring device has an open portion in at least one of the attachments attached using screws. Thus, the screw fixing member for fixing the screw, which is accommodated in the boss portion located on the inner surface side of the peripheral wall surrounding the inner space and inserted into the insertion hole of the boss portion from the open portion side. The screw fixing member is made of a plate material. The screw fixing member includes a pair of leg pieces that are close to or in contact with the opposite side walls of the receiving space provided in the boss portion so as to communicate with the insertion hole so that the plate surface faces. The leg piece is bent from one end in the axial direction of the insertion hole, extends toward the insertion hole side, and the tip engages with the screw shaft portion of the screw inserted into the insertion hole. A pair of elastic engagement pieces and a connecting piece for connecting the pair of leg pieces are provided. Therefore, for the insertion of the screw shaft portion into the insertion hole, the elastic engagement piece is inclined in the insertion direction of the screw shaft portion, or the inclination in the insertion direction is increased. By elastically deforming, the screw shaft portion is allowed to move in the insertion direction, and the elastic engagement engaged with the screw shaft portion is prevented from coming off from the insertion hole. The piece is elastically deformed in the removal direction of the elastic engagement piece by pressing the screw shaft portion so as to be elastically deformed so that the inclination in the insertion direction is reduced in the removal direction of the screw shaft portion. Deformation is difficult to prevent the screw shaft portion from moving in the pulling direction.

これにより、取着体に配線器具等の被取着物を取り付けるには、この取着体のボス部に設けられた挿入孔に、開放部側からビスを押し込むように押圧する。こうすることで、ビス固定部材に設けられた弾性係合片の先端部分が、ビス軸部に押圧される。それに共なって、弾性係合片が、ビス軸部の挿入方向へ傾斜するように、あるいは、挿入方向への傾斜が増すように弾性変形して、ビス軸部の、挿入方向への移動が許容されて、このビス軸部は、挿入孔に挿入される。そして、ビスの押し込みを終えると、弾性係合片の先端は、ビス軸部と係合し、こうして、ビスが固定され、被取着物は、取着体に取着される。ここにおいて、挿入孔からのビス軸部の抜けに対しては、ビス軸部と係合した弾性係合片が、ビス軸部につられて、その抜け方向へ、すなわち前記挿入方向への傾斜が減ずる方向へ弾性変形しようとして、弾性係合片は、ビス軸部を押圧する。そして、この押圧により、弾性係合片は、前記抜け方向への弾性変形が困難となるとともに、ビス軸部への係合が強固なものとなり、ビスの抜けが阻止される。ここで、ビス固定部材は、一対の弾性係合片が延設される一対の脚片を備えており、それら脚片は、収容空間の向かい合う側壁面に、板面が面するようにして近接あるいは当接する。したがって、一対の脚片、ひいては一対の弾性係合片は、互いに離れることはなく、弾性係合片の、ビス軸部との係合力が十分に確保される。   Thus, in order to attach an object to be attached such as a wiring device to the attachment body, a screw is pushed into the insertion hole provided in the boss portion of the attachment body from the open portion side. By doing so, the tip end portion of the elastic engagement piece provided on the screw fixing member is pressed against the screw shaft portion. At the same time, the elastic engagement piece is elastically deformed so as to incline in the insertion direction of the screw shaft part or to increase the inclination in the insertion direction, so that the screw shaft part moves in the insertion direction. Allowed, this screw shaft portion is inserted into the insertion hole. Then, when the screw has been pushed in, the tip of the elastic engagement piece engages with the screw shaft portion, and thus the screw is fixed, and the adherend is attached to the attachment body. Here, when the screw shaft portion is removed from the insertion hole, the elastic engagement piece engaged with the screw shaft portion is attached to the screw shaft portion, and the inclination in the removal direction, that is, the insertion direction is inclined. The elastic engagement piece presses the screw shaft portion in an attempt to elastically deform in the decreasing direction. By this pressing, the elastic engagement piece becomes difficult to be elastically deformed in the removal direction, and the engagement with the screw shaft portion becomes strong, and the screw is prevented from coming off. Here, the screw fixing member is provided with a pair of leg pieces to which a pair of elastic engagement pieces are extended, and these leg pieces are close to each other so that a plate surface faces a side wall surface facing the accommodation space. Or it contacts. Therefore, the pair of leg pieces and thus the pair of elastic engagement pieces are not separated from each other, and the engagement force of the elastic engagement pieces with the screw shaft portion is sufficiently ensured.

この発明に係る取着体およびビス固定部材によれば、収容空間の向かい合う側壁面によって、一対の脚片、ひいては一対の弾性係合片は、互いに離れることはないので、ビスとの係合力を十分に確保して、被取着物を確実に取着することができる。   According to the attachment body and the screw fixing member according to the present invention, the pair of leg pieces and thus the pair of elastic engagement pieces are not separated from each other by the opposing side wall surfaces of the accommodation space. Sufficiently secures the object to be attached.

以下、この発明に係る取着体およびビス固定部材を実施するための最良の形態を図面に基づいて説明する。   The best mode for carrying out an attachment body and a screw fixing member according to the present invention will be described below with reference to the drawings.

図1ないし図5は、本発明の一実施の形態を示す。図中符号1は、建物の壁である。2は、被取着物としての、コンセントとかスイッチ等の配線器具である。3は、その配線器具2を保持する保持材としての保持パネルである。4は、固着具としてのビスである。5は、前記配線器具2がビス4を用いて取着される、取着体としての配線用ボックスである。   1 to 5 show an embodiment of the present invention. Reference numeral 1 in the figure denotes a building wall. Reference numeral 2 denotes a wiring device such as an outlet or a switch as an attachment. Reference numeral 3 denotes a holding panel as a holding material for holding the wiring device 2. 4 is a screw as a fixing tool. Reference numeral 5 denotes a wiring box as an attachment body to which the wiring device 2 is attached using screws 4.

ここで、保持パネル3は、枠状に形成されており、その枠内に、配線器具2が取り付けられる。そして、保持パネル3は、その各側、例えば上下の各側に、ビス4が挿通される孔3aが形成されている。   Here, the holding panel 3 is formed in a frame shape, and the wiring device 2 is attached in the frame. The holding panel 3 is formed with holes 3a through which the screws 4 are inserted on each side thereof, for example, the upper and lower sides.

配線用ボックス5は、一方に開放部5aを有する内部空間5bを形成するようにその内部空間5bを囲む周壁5cと、周壁5cの内面側に位置するボス部6、6とを備えている。そして、ボス部6は、ビス4が前記開放部5a側から挿入される挿入孔6aと、その挿入孔6aと連通する収容空間6bとを有する。ここにおいて、ボス部6内には(詳細には、収容空間6bには)、前記開放部5a側から挿入孔6aに挿入されたビス4を固定するためのビス固定部材7が収容されている。このビス固定部材7は、板材からなり、一対の脚片7a、7aと、一対の弾性係合片7b、7bと、前記一対の脚片7a、7aを連結する連結片7cとを備える。一対の脚片7a、7aは、前記収容空間6bの向かい合う側壁面6c、6cに、板面が面するようにして近接あるいは当接するものである。そして、一対の弾性係合片7b、7bは、挿入孔6aを挟んで対向位置するように、一対の脚片7a、7aの、前記挿入孔6aの軸心方向の一方の端から折れ曲がって、挿入孔6a側に向かって延設され、先端が、挿入孔6aに挿入された前記ビス4のビス軸部4aに係合するものである。   The wiring box 5 includes a peripheral wall 5c surrounding the internal space 5b so as to form an internal space 5b having an open portion 5a on one side, and bosses 6 and 6 positioned on the inner surface side of the peripheral wall 5c. And the boss | hub part 6 has the insertion hole 6a in which the screw | thread 4 is inserted from the said opening part 5a side, and the accommodation space 6b connected with the insertion hole 6a. Here, a screw fixing member 7 for fixing the screw 4 inserted into the insertion hole 6a from the open portion 5a side is accommodated in the boss portion 6 (specifically, in the accommodation space 6b). . The screw fixing member 7 is made of a plate material, and includes a pair of leg pieces 7a and 7a, a pair of elastic engagement pieces 7b and 7b, and a connecting piece 7c that connects the pair of leg pieces 7a and 7a. The pair of leg pieces 7a, 7a are close to or abut against the opposing side wall surfaces 6c, 6c of the accommodation space 6b so that the plate surfaces face each other. The pair of elastic engagement pieces 7b and 7b are bent from one end of the pair of leg pieces 7a and 7a in the axial direction of the insertion hole 6a so as to be opposed to each other with the insertion hole 6a interposed therebetween. It extends toward the insertion hole 6a, and its tip engages with the screw shaft portion 4a of the screw 4 inserted into the insertion hole 6a.

そこで、挿入孔6aへのビス軸部4aの挿入に対しては、弾性係合片7bは、ビス軸部4aの挿入方向Pへ傾斜するように、あるいは、挿入方向Pへの傾斜が増すように(図示実施の形態においては、挿入方向Pへの傾斜が増すように)弾性変形することで、ビス軸部4aの、前記挿入方向Pへの移動を許容する。反対に、挿入孔6aからのビス軸部4aの抜けに対しては、ビス軸部4aと係合した弾性係合片7bが、ビス軸部4aの抜け方向Qへ、前記挿入方向Pへの傾斜が減ずるように弾性変形しようとして、ビス軸部4aを押圧することにより、弾性係合片7bの、前記抜け方向Qへの弾性変形を困難にして、ビス軸部4aの、前記抜け方向Qへの移動を阻止する。   Therefore, when the screw shaft portion 4a is inserted into the insertion hole 6a, the elastic engagement piece 7b is inclined in the insertion direction P of the screw shaft portion 4a or the inclination in the insertion direction P is increased. Further, in the illustrated embodiment, the screw shaft portion 4a is allowed to move in the insertion direction P by being elastically deformed (so that the inclination in the insertion direction P is increased). On the contrary, when the screw shaft portion 4a is removed from the insertion hole 6a, the elastic engagement piece 7b engaged with the screw shaft portion 4a moves in the removal direction Q of the screw shaft portion 4a in the insertion direction P. By pressing the screw shaft portion 4a in an attempt to be elastically deformed so that the inclination is reduced, it is difficult to elastically deform the elastic engagement piece 7b in the pulling direction Q, and the screw shaft portion 4a has the pulling direction Q. Stop moving to.

具体的には、配線用ボックス5は、例えば合成樹脂製であって、前側に前記開放部5aを備えた箱型形状、例えば直方体形状をしている。そこで、ボス部6は、配線用ボックス5の、例えば上下の各側に、周壁5cから内部空間5b側に突出するようにして形成される。そして、このボス部6に、配線用ボックス5の前側(つまり、前記開放部5a側)から後方に向かって、前記挿入孔6aが形成される。また、ボス部6には、前記収容空間6bが、周壁5cの外面側から挿入孔6aに向かって連通、すなわち交差(図示実施の形態においては直交)するように明けられている。そして、図示実施の形態においては、この収容空間6bの前記側壁面6cは、挿入孔6aの軸心方向に平行となるように形成されている。   Specifically, the wiring box 5 is made of, for example, a synthetic resin, and has a box shape with the opening 5a on the front side, for example, a rectangular parallelepiped shape. Therefore, the boss portion 6 is formed on each of the upper and lower sides of the wiring box 5 so as to protrude from the peripheral wall 5c toward the internal space 5b. And the insertion hole 6a is formed in this boss | hub part 6 toward the back from the front side (namely, the said opening part 5a side) of the box 5 for wiring. The housing space 6b is opened in the boss portion 6 so as to communicate from the outer surface side of the peripheral wall 5c toward the insertion hole 6a, that is, to intersect (orthogonally in the illustrated embodiment). In the illustrated embodiment, the side wall surface 6c of the accommodation space 6b is formed to be parallel to the axial direction of the insertion hole 6a.

ビス固定部材7は、前側(つまり、前記開放部5a側)からボス部6の挿入孔6aに挿入されたビス4と係合してそのビス4を固定するためのものであり、ばね性を有する板材、例えば、鋼板とか銅合金板等の金属板からなる。そして、前記脚片7a、7aは、それぞれが略長方形状に形成され、その短辺が、挿入孔6aの軸心方向を向くようにして、互いに平行となるように位置し、脚片7a、7aの板面が、収容空間6bにおける左右の(つまり、後述する横方向Sのそれぞれに設けられた)側壁面6c、6cに平行状態で面して、その側壁面6c、6cに近接あるいは当接するように配置される。   The screw fixing member 7 is for engaging with the screw 4 inserted into the insertion hole 6a of the boss portion 6 from the front side (that is, the opening portion 5a side) and fixing the screw 4, and has a spring property. It has a plate material, for example, a metal plate such as a steel plate or a copper alloy plate. The leg pieces 7a, 7a are each formed in a substantially rectangular shape, and the short sides thereof are positioned so as to be parallel to each other so as to face the axial direction of the insertion hole 6a. The plate surface of 7a faces the side wall surfaces 6c, 6c in the accommodation space 6b in parallel with the left and right side walls (that is, provided in each of the lateral directions S described later), and is close to or close to the side wall surfaces 6c, 6c Arranged to touch.

前記弾性係合片7b、7bは、脚片7a、7aの、挿入孔6aの軸心方向の一方の端の長辺(図示実施の形態においては、前側の辺)から折れ曲がって、挿入孔6a側に向かうとともに、若干ビス軸部4aの挿入方向Pに傾くように延設されている。そして、弾性係合片7bの先端には、挿入孔6aに挿入されたビス軸部4aの外周に沿うように、弧状の凹部7dが形成されている。すなわち、この凹部7dが、挿入孔6aに挿入されたビス軸部4aに係合するようになっている。   The elastic engagement pieces 7b and 7b are bent from the long side (the front side in the illustrated embodiment) of one end of the leg pieces 7a and 7a in the axial direction of the insertion hole 6a, and the insertion hole 6a As it goes to the side, it extends so as to be slightly inclined in the insertion direction P of the screw shaft portion 4a. And the arc-shaped recessed part 7d is formed in the front-end | tip of the elastic engagement piece 7b so that the outer periphery of the screw shaft part 4a inserted in the insertion hole 6a may be followed. That is, the recess 7d is adapted to engage with the screw shaft portion 4a inserted into the insertion hole 6a.

前記連結片7cは、弾性係合片7b、7bとは縁切りされた状態で、一対の脚片7a、7aの前記一方の端の長辺(図示実施の形態においては、前側の辺)どうしを繋ぐように設けられている。そこで、ビス固定部材7は、一対の弾性係合片7b、7bが、内部空間5b側(つまり、ボス部6の先端側)とその内部空間5b側とは反対側となる外方側(つまり、ボス部6の基端側)とを結ぶ縦方向Rに直交する横方向S(図示実施の形態においては、左右方向)に並ぶように、かつ、連結片7cが、一対の弾性係合片7b、7bに対して、内部空間5b側とは反対側となる外方側に位置するように、配置される(図4参照)。   The connecting piece 7c is cut off from the elastic engagement pieces 7b and 7b, and the long sides (front sides in the illustrated embodiment) of the one ends of the pair of leg pieces 7a and 7a are connected to each other. It is provided to connect. Therefore, the screw fixing member 7 has a pair of elastic engagement pieces 7b, 7b on the outer side (that is, on the side opposite to the inner space 5b side) (that is, the tip end side of the boss portion 6). , And the connecting piece 7c is a pair of elastic engaging pieces so as to be aligned in the lateral direction S (in the illustrated embodiment, the left-right direction) orthogonal to the longitudinal direction R connecting the base end side of the boss portion 6). 7b and 7b are arranged so as to be located on the outer side opposite to the inner space 5b side (see FIG. 4).

次に、以上の構成からなる配線用ボックス5およびビス固定部材7の作用効果について説明する。この配線用ボックス5は、予め、壁1の裏側の柱等に、木ねじ等の固着具により取り付けられている。そこで、この配線用ボックス5に配線器具2を取り付けるには、配線用ボックス5に対応して壁1に明けられた壁孔1a部分における、壁1の表側に、配線器具2を取り付けた保持パネル3を宛がう。その後、ビス4(詳細には、ビス軸部4a)を保持パネル3の孔3aに通し、この配線用ボックス5のボス部6に設けられた挿入孔6aに、前側(すなわち、開放部5a側)からビス4を押し込むように押圧する。こうすることで、ビス固定部材7に設けられた弾性係合片7b、7bの先端部分が、ビス軸部4aに押圧される。それに共なって、弾性係合片7b、7bが、ビス軸部4aの挿入方向Pへ傾斜するように、あるいは、挿入方向Pへの傾斜が増すように弾性変形して、ビス軸部4aの、挿入方向Pへの移動が許容され、このビス軸部4aは、一対の弾性係合片7b、7b間に挿通されるようにして、挿入孔6aに挿入される。そして、ビス4の押し込みを終えると、弾性係合片7b、7bの先端(詳細には、凹部7d、7d)は、ビス軸部4aと係合し、こうして、ビス4が固定され、配線器具2は、保持パネル3とともに配線用ボックス5に取着される。   Next, functions and effects of the wiring box 5 and the screw fixing member 7 having the above-described configuration will be described. The wiring box 5 is previously attached to a column or the like on the back side of the wall 1 with a fixing tool such as a wood screw. Therefore, in order to attach the wiring device 2 to the wiring box 5, a holding panel in which the wiring device 2 is attached to the front side of the wall 1 in the wall hole 1 a portion opened in the wall 1 corresponding to the wiring box 5. 3 is assigned. Thereafter, the screw 4 (specifically, the screw shaft portion 4a) is passed through the hole 3a of the holding panel 3, and the insertion hole 6a provided in the boss portion 6 of the wiring box 5 is inserted into the front side (that is, the open portion 5a side). ) To push in the screw 4. By doing so, the tip portions of the elastic engagement pieces 7b, 7b provided on the screw fixing member 7 are pressed against the screw shaft portion 4a. At the same time, the elastic engagement pieces 7b, 7b are elastically deformed so as to incline in the insertion direction P of the screw shaft portion 4a or increase in the inclination in the insertion direction P, and the screw shaft portion 4a The screw shaft portion 4a is inserted into the insertion hole 6a so as to be inserted between the pair of elastic engagement pieces 7b, 7b. When the push-in of the screw 4 is finished, the tips of the elastic engagement pieces 7b, 7b (specifically, the recesses 7d, 7d) engage with the screw shaft portion 4a, and thus the screw 4 is fixed, and the wiring device 2 is attached to the wiring box 5 together with the holding panel 3.

ここにおいて、挿入孔6aからのビス軸部4aの抜けに対しては、ビス軸部4aと係合した弾性係合片7b、7bが、ビス軸部4aにつられて、その抜け方向Qへ、すなわち前記挿入方向Pへの傾斜が減ずる方向へ弾性変形しようとして、弾性係合片7b、7bは、ビス軸部4aを押圧する。そして、この押圧により、弾性係合片7b、7bは、前記抜け方向Qへの弾性変形が困難となるとともに、ビス軸部4aへの係合が強固なものとなり、ビス4の抜けが阻止される。ここで、ビス固定部材7は、一対の弾性係合片7b、7bが延設される一対の脚片7a、7aを備えており、それら脚片7a、7aは、収容空間6bの向かい合う側壁面6c、6cに、板面が面するようにして近接あるいは当接する。したがって、一対の脚片7a、7a、ひいては一対の弾性係合片7b、7bは、互いに離れることはない。こうして、弾性係合片7b、7bの、ビス軸部4aとの係合力を十分に確保することができ、この配線用ボックス5に配線器具2を確実に取着することができる。   Here, the elastic engagement pieces 7b and 7b engaged with the screw shaft portion 4a are attached to the screw shaft portion 4a in the removal direction Q for the removal of the screw shaft portion 4a from the insertion hole 6a. That is, the elastic engagement pieces 7b and 7b press the screw shaft portion 4a in an attempt to elastically deform in a direction in which the inclination in the insertion direction P is reduced. By this pressing, the elastic engagement pieces 7b and 7b are difficult to be elastically deformed in the removal direction Q, and the engagement with the screw shaft portion 4a becomes strong, and the screw 4 is prevented from coming off. The Here, the screw fixing member 7 is provided with a pair of leg pieces 7a, 7a from which a pair of elastic engagement pieces 7b, 7b are extended, and these leg pieces 7a, 7a are opposite side wall surfaces of the accommodation space 6b. 6c, 6c approaches or abuts so that the plate surface faces. Therefore, the pair of leg pieces 7a and 7a and thus the pair of elastic engagement pieces 7b and 7b are not separated from each other. Thus, the engagement force of the elastic engagement pieces 7b, 7b with the screw shaft portion 4a can be sufficiently secured, and the wiring device 2 can be securely attached to the wiring box 5.

また、ビス固定部材7は、一対の脚片7a、7aを連結する連結片7cを備えている。そこで、この連結片7cを、一対の弾性係合片7b、7bに対して、内部空間5b側とは反対側となる外方側(つまり、ボス部6の基端側)に位置させることで、ビス4の位置、すなわち挿入孔6aの位置を変えることができない場合であっても、内部空間5bを広く取ることができる。したがって、この内部空間5bに大きな配線器具2や、例えば、三つ並んで配置された配線器具2、2とか、二つが上下等に離れて配置された配線器具2、2とかの複数の配線器具2、2を収容することができたり、あるいは、余裕を持って収容することができる。   The screw fixing member 7 includes a connecting piece 7c that connects the pair of leg pieces 7a, 7a. Therefore, by positioning the connecting piece 7c on the outer side (that is, the base end side of the boss portion 6) opposite to the inner space 5b side with respect to the pair of elastic engaging pieces 7b and 7b. Even when the position of the screw 4, that is, the position of the insertion hole 6a cannot be changed, the internal space 5b can be widened. Therefore, a large number of wiring devices 2, such as a large wiring device 2 in this internal space 5b, for example, three wiring devices 2, 2 arranged side by side, or two wiring devices 2, 2 arranged so as to be vertically separated from each other. 2, 2 can be accommodated, or can be accommodated with a margin.

ところで、配線用ボックス5に配線器具2を取り付ける際に、配線用ボックス5の挿入孔6aにビス4のビス軸部4aを押し込んだ後、さらに、そのビス4を、その締め付け方向に回動してもよい。このように、ビス4に締め付け方向の回動を加えることで、この配線用ボックス5に配線器具2を強固に固定することが可能となる。   By the way, when attaching the wiring device 2 to the wiring box 5, after the screw shaft portion 4a of the screw 4 is pushed into the insertion hole 6a of the wiring box 5, the screw 4 is further rotated in the tightening direction. May be. In this way, the wiring device 2 can be firmly fixed to the wiring box 5 by turning the screw 4 in the tightening direction.

反対に、配線用ボックス5から配線器具2を取り外すには、弾性係合片7bが係合したビス4を、その緩み方向に回動する。こうすることで、ビス4は、後退してボス部6(詳細には、挿入孔6a)から取り除かれ、配線器具2は、保持パネル3とともに、配線用ボックス5から取り外される。   On the contrary, in order to remove the wiring device 2 from the wiring box 5, the screw 4 engaged with the elastic engagement piece 7b is rotated in the loosening direction. By doing so, the screw 4 is retracted and removed from the boss portion 6 (specifically, the insertion hole 6a), and the wiring device 2 is removed from the wiring box 5 together with the holding panel 3.

なお、本発明は、上述した実施の形態に限定されるわけではなく、その他種々の変更が可能である。例えば、ビス固定部材7の連結片7cは、図6に示すように、一対の脚片7a、7aの、挿入孔6aの軸心方向と直交する方向の端どうしを繋ぐように設けられてもよい。そして、この場合にも、ビス固定部材7は、一対の弾性係合片7b、7bが、内部空間5b側(つまり、ボス部6の先端側)とその内部空間5b側とは反対側となる外方側(つまり、ボス部6の基端側)とを結ぶ縦方向Rに直交する横方向Sに並ぶように、かつ、連結片7cが、一対の弾性係合片7b、7bに対して、内部空間5b側とは反対側となる外方側に位置するように、配置されるのが望ましい。   In addition, this invention is not necessarily limited to embodiment mentioned above, A various other change is possible. For example, as shown in FIG. 6, the connecting piece 7c of the screw fixing member 7 may be provided so as to connect ends of the pair of leg pieces 7a, 7a in a direction perpendicular to the axial direction of the insertion hole 6a. Good. Also in this case, the screw fixing member 7 has a pair of elastic engagement pieces 7b and 7b on the side opposite to the inner space 5b side (that is, the tip side of the boss portion 6) and the inner space 5b side. The connecting piece 7c is aligned with the pair of elastic engagement pieces 7b and 7b so as to be aligned in the horizontal direction S perpendicular to the vertical direction R connecting the outer side (that is, the base end side of the boss portion 6). The inner space 5b is preferably disposed so as to be located on the outer side opposite to the inner space 5b side.

もっとも、収容空間6bにおける側壁面6c、6cを左右ではなく上下(すなわち、内部空間5b側とその内部空間5b側とは反対側となる外方側とを結ぶ縦方向Rのそれぞれ)に設け、ビス固定部材7を、一対の弾性係合片7b、7bが、これら側壁面6c、6cと対応するように、上下方向(前記縦方向R)に並ぶように、配置しても構わない。   However, the side wall surfaces 6c and 6c in the accommodation space 6b are provided not vertically but vertically (that is, in the longitudinal direction R connecting the inner space 5b side and the outer side opposite to the inner space 5b side), The screw fixing member 7 may be arranged so that the pair of elastic engagement pieces 7b and 7b are aligned in the vertical direction (the vertical direction R) so as to correspond to the side wall surfaces 6c and 6c.

また、弾性係合片7bは、脚片7aの、挿入孔6aの軸心方向の一方の端となる、前側の端から折れ曲がって形成されているが、反対に、脚片7aの、挿入孔6aの軸心方向の一方の端となる、後側の端から折れ曲がるようにして形成されてもよい。   The elastic engagement piece 7b is formed by bending from the front end, which is one end of the leg piece 7a in the axial direction of the insertion hole 6a. It may be formed so as to be bent from the rear end, which is one end in the axial direction of 6a.

また、弾性係合片7bは、ビス軸部4aが挿入孔6aに挿入される前から挿入方向Pに傾斜していてもよいが、ビス軸部4aが挿入される前においては、挿入孔6aの軸心方向と直交し、ビス軸部4aを挿入することで、弾性係合片7bが、ビス軸部4aに押されて、そのビス軸部4aの挿入方向Pへ傾斜するように、弾性変形するものであってもよい。   Further, the elastic engagement piece 7b may be inclined in the insertion direction P before the screw shaft portion 4a is inserted into the insertion hole 6a, but before the screw shaft portion 4a is inserted, the insertion hole 6a. The elastic engagement piece 7b is pushed by the screw shaft portion 4a so as to be inclined in the insertion direction P of the screw shaft portion 4a by inserting the screw shaft portion 4a. It may be deformed.

また、取着体は、内部空間5bが一方に開放部5aを有する配線用ボックス5等でなくとも、内部空間が一方に開放部を有するとともに他方にも開放する枠状の取着体であってもよい。この枠状の取着体としては、例えば被取着物としての配線器具2が取着されるとともに配線用ボックスに取り付けられる配線用ボックスカバー等がある。ここで、配線用ボックスカバーとしては、塗代付きのボックスカバーとか板状のボックスカバー等がある。さらに、取着体は、これら配線用ボックス5とか配線用ボックスカバーでなくとも、被取着物がビス4を用いて取着されるものであればどのようなものでもよい。   Further, the attachment body is a frame-like attachment body in which the internal space has an open portion on one side and is open to the other, even if the internal space 5b is not the wiring box 5 having the open portion 5a on one side. May be. As this frame-shaped attachment, for example, there is a wiring box cover to which the wiring device 2 as an attachment is attached and attached to the wiring box. Here, as the wiring box cover, there are a box cover with coating, a plate-shaped box cover, and the like. Further, the attachment body is not limited to the wiring box 5 or the wiring box cover, and any attachment body can be used as long as the attachment object is attached using the screws 4.

また、被取着物は、配線器具2でなくとも、例えば、取着体としての配線用ボックス5に取着される配線用ボックスカバーであってもよく、配線器具2に限定されるものではない。   In addition, the attachment object may be a wiring box cover that is attached to the wiring box 5 as the attachment body, and is not limited to the wiring equipment 2, instead of the wiring equipment 2. .
