Description

この発明は、建築物内の壁に設置された配線用ボックスの配線器具取付部に螺合されて、配線用ボックスに配線器具を取付可能とする配線器具固定用ビスを備えた配線用ボックスに関するものである。 This invention is screwed to the wiring device attachment portion of the installed wiring box in the wall of the building, the wiring box with a wiring accessory fixing bi scan that can be attached to wire instrument wiring box It is about.

従来より建築物内の壁の表面にコンセント等の配線器具を取り付けるために壁裏には配線用ボックスが設置され、この配線用ボックスは開口を有する有底四角箱状をなすボックス本体を備えている。そのボックス本体の底板上には配線用ボックスに対して配線器具を取り付ける際に使用される一対の配線器具固定用ビスが保持されている。また、ボックス本体の一側壁には、その側壁を貫通してビス孔が２箇所に形成され、そのビス孔から壁裏側に立設された柱にビスを固定することにより、配線用ボックスを柱に取り付けることができるようになっている。 Conventionally, a wiring box has been installed on the back of the wall to attach a wiring device such as an outlet to the surface of the wall in the building, and this wiring box has a box body having a bottomed square box shape having an opening. Yes. On the bottom plate of the box body, a pair of wiring device fixing screws used when the wiring device is attached to the wiring box is held. Also, one side wall of the box body is formed with two screw holes penetrating the side wall, and the screws are fixed to the pillars erected on the back side of the wall from the screw holes. Can be attached to.

ボックス本体の上下両側壁の内側面には、それぞれボックス本体の開口側に臨む配線器具取付部が相対向して形成され、各配線器具取付部内には、前記配線器具固定用ビスの雄ねじが螺合可能な雌ねじが螺刻された雌ねじ部が形成されている。各配線器具取付部の前面にはそれぞれ取付孔が形成され、各取付孔から前記雌ねじ部に前記配線器具固定用ビスを挿入して螺合することができるようになっている。配線器具を保持した状態で配線用ボックスに取り付けられる配線器具保持枠は、四角枠状をなし、その上下両端部には前記取付孔に対応する孔が形成されている。 On the inner side surfaces of the upper and lower side walls of the box body, wiring device mounting portions facing the opening side of the box body are formed opposite to each other, and the male screws of the wiring device fixing screws are screwed into the wiring device mounting portions. A female thread portion is formed by threading a matable female thread. A mounting hole is formed in the front surface of each wiring device mounting portion, and the wiring device fixing screw can be inserted and screwed into the female screw portion from each mounting hole. The wiring device holding frame attached to the wiring box while holding the wiring device has a square frame shape, and holes corresponding to the mounting holes are formed at both upper and lower ends thereof.

そして、この配線用ボックスを使用して配線器具を壁表に取り付けるには、まず、配線用ボックスをその前面が前記柱の前面と面一になるように柱に取り付け、その配線用ボックス内に、ケーブルを長さに余裕を持った余長部を有した状態で収容する。次いで、柱及び配線用ボックスの前方に壁材を設置し、壁を形成する。その壁表に貫通孔を開け、配線用ボックスの開口を壁表側に臨ませる。 In order to attach the wiring fixture to the wall surface using this wiring box, first attach the wiring box to the pillar so that its front surface is flush with the front surface of the pillar, and place it in the wiring box. The cable is accommodated in a state having an extra length portion having a margin in length. Next, a wall material is installed in front of the pillar and the wiring box to form a wall. A through hole is made on the wall surface so that the opening of the wiring box faces the wall surface side.

次に、配線用ボックス内のケーブルに配線器具を接続し、その配線器具を配線器具保持枠に保持させる。続いて、一対の配線器具固定用ビスを底板から取り外し、前記配線器具保持枠の孔から配線器具固定用ビスを前記雌ねじ部に螺合して、配線器具保持枠を介して配線器具を配線用ボックスに取付ける。このとき、配線器具固定用ビスは底板に予め保持されているため、配線器具固定用ビスを別途用意する場合と異なり配線器具の取付作業の簡易化が図られる。その結果、配線器具が配線用ボックス内に収容されるとともに、壁に取付けられる。 Next, the wiring device is connected to the cable in the wiring box, and the wiring device is held by the wiring device holding frame. Subsequently, the pair of wiring device fixing screws are removed from the bottom plate, and the wiring device fixing screws are screwed into the female screw portions from the holes of the wiring device holding frame, and the wiring device is connected to the wiring device via the wiring device holding frame. Install in the box. At this time, since the wiring device fixing screw is held in advance on the bottom plate, the wiring device fixing operation can be simplified unlike the case where the wiring device fixing screw is separately prepared. As a result, the wiring device is accommodated in the wiring box and attached to the wall.

前記配線器具固定用ビスは軸部の軸線方向への長さが４０ｍｍ程度に設定されている。これは配線用ボックスの前面に配置される構築材が例外的に著しく厚くなる場合、例えば壁材の厚みが厚く（例えば厚さ１２．５ｍｍ）、その壁材の表面に厚い仕上壁材が別途設けられ、さらには配線用ボックスの前面に胴縁材（厚さ１５ｍｍ）が設置されるような場合であっても配線器具固定用ビスを各構築材を貫通して配線器具取付部に螺合可能とするためである。 The wiring device fixing screw has a length in the axial direction of the shaft portion set to about 40 mm. This is because if the construction material placed on the front surface of the wiring box is exceptionally thick, for example, the wall material is thick (eg, 12.5 mm thick), and a thick finish wall material is separately provided on the surface of the wall material. In addition, even when a frame material (thickness 15 mm) is installed on the front surface of the wiring box, the wiring device fixing screws are threaded through the construction materials and screwed into the wiring device mounting portion. This is to make it possible.

ところが、実際には配線用ボックスの前面には前記のような構築材が設置される場合がほとんどなく、厚さ３ｍｍ程度のプラスチックボードのみが壁材として設置されたり、配線用ボックスの前面に泥壁が形成されて壁材が設置されない場合もある。即ち、ほとんどの場合、配線器具固定用ビスはその軸線方向への長さが４０ｍｍより短くても配線器具取付部に螺合可能となる。従って、配線器具固定用ビスの軸部の軸線方向への長さが４０ｍｍ必要としない場合にも、上記配線器具固定用ビスを使用して配線器具を配線用ボックスに取り付けなければならない。その結果、配線器具取付部の雌ねじ部に対する雄ねじの螺合量が多くなり、配線器具の取付作業が非常に面倒であるという問題があった。 However, in reality, the construction material as described above is rarely installed on the front surface of the wiring box, and only a plastic board having a thickness of about 3 mm is installed as a wall material, or mud is formed on the front surface of the wiring box. In some cases, walls are formed and no wall material is installed. That is, in most cases, the wiring device fixing screw can be screwed into the wiring device mounting portion even if its length in the axial direction is shorter than 40 mm. Accordingly, even when the length of the shaft portion of the wiring device fixing screw in the axial direction is not required to be 40 mm, the wiring device must be attached to the wiring box using the wiring device fixing screw. As a result, there has been a problem that the amount of male screw engagement with the female thread portion of the wiring device mounting portion is increased, and the mounting operation of the wiring device is very troublesome.

また、近年の住宅事情においては、壁の厚みが薄くなる傾向にあり、その壁に対応するために配線用ボックスはその厚みが薄く形成されたものが使用されている。そのため、例えば、前記薄型の配線用ボックス（例えば厚さ３０ｍｍ）を使用し、その配線用ボックスの前面に泥壁を形成して配線器具取付部に配線器具固定用ビスを螺合すると、その配線器具固定用ビスの先端がボックス本体の底板から突出してしまう。その結果、配線器具固定用ビスが壁内に収まらなくなり、その薄型の配線用ボックスを使用して配線器具を壁に取り付けることができなくなるという問題もあった。 In recent housing circumstances, the wall tends to be thin, and a wiring box having a thin thickness is used to accommodate the wall. Therefore, for example, when the thin wiring box (for example, 30 mm in thickness) is used, a mud wall is formed on the front surface of the wiring box and the wiring device fixing screw is screwed into the wiring device mounting portion, the wiring The tip of the instrument fixing screw protrudes from the bottom plate of the box body. As a result, there has been a problem that the wiring fixture fixing screw cannot fit in the wall and the wiring fixture cannot be attached to the wall using the thin wiring box.

さらに、前記薄型の配線用ボックスはその内部空間を広くし、前記余長部を有するケーブルを収容可能とすべく形成されている。即ち、配線用ボックス内において、配線器具取付部が配線用ボックスの前面のみに形成されて底板方向へ延設されておらず、配線器具取付部の下端部と底板との間に空間が形成されている。 Further, the thin wiring box is formed so as to widen the internal space and accommodate the cable having the extra length. That is, in the wiring box, the wiring fixture mounting portion is formed only on the front surface of the wiring box and does not extend toward the bottom plate, and a space is formed between the lower end portion of the wiring fixture mounting portion and the bottom plate. ing.

そのため、配線器具取付部に配線器具固定用ビスを螺合するとその配線器具固定用ビスが配線用ボックス内で露出してしまい、配線用ボックス内に収容された余長部を有するケーブルや、そのケーブルと配線器具との接続部に配線器具固定用ビスが接触したりするおそれがあるという問題があった。加えて、配線用ボックス内に収容されたケーブルを壁表側に引き出すとき、ケーブルが配線器具固定用ビスに絡んだりしてケーブルの壁表への引き出し作業が行いにくくなるという問題もあった。 Therefore, when the wiring fixture fixing screw is screwed into the wiring fixture mounting portion, the wiring fixture fixing screw is exposed in the wiring box, and the cable having the extra length portion accommodated in the wiring box, There has been a problem that there is a risk that the wiring device fixing screw may come into contact with the connection portion between the cable and the wiring device. In addition, when the cable housed in the wiring box is pulled out to the wall surface side, there is a problem that the cable is entangled with the wiring fixture fixing screw, making it difficult to pull out the cable to the wall surface.

この発明は、このような従来技術に存在する問題点に着目してなされたものである。その目的とするところは、軸部の軸線方向への長さを短くすることができ、配線器具の配線用ボックスへの取付作業の簡易化を図ることができる配線器具固定用ビスを備えた配線用ボックスを提供することにある。 The present invention has been made paying attention to such problems existing in the prior art.

The bottom plate 24 of the box body 23 has a planar rectangular shape, and side walls 25 to 28 corresponding to the respective sides of the bottom plate 24 are substantially directed to the bottom plate 24 toward the front (left side in FIG. 3). Stands vertically. The length of each side wall 25-28 in the width direction, that is, the thickness of the box body 23 is set to T1.

前記ボックス本体２３の上下両側壁２５，２６の相対向する両側部には、それぞれボックス本体２３の開口に連通する連通部２３ａが形成され、各連通部２３ａの外端縁には平面円形状をなし、ケーブル３９が配線可能な配線貫通孔２９が形成されている。ボックス本体２３の上側壁２５及び下側壁２６の内面中央には、それぞれ上側壁２５及び下側壁２６の前端から底板２４側へ延びる配線器具取付部３０が一体形成され、各配線器具取付部３０の前面には取付孔３０ａが形成されている。また、図４に示すように、前記取付孔３０ａは、ボックス本体２３の前面開口に臨み各配線器具取付部３０内には内周に前記固定用ビス１１の雄ねじが螺合可能な雌ねじが螺刻された雌ねじ部３０ｂが形成されている。 On both opposite sides of the upper and lower side walls 25, 26 of the box main body 23, communication portions 23a communicating with the openings of the box main body 23 are formed, and a planar circular shape is formed on the outer edge of each communication portion 23a. None, a wiring through hole 29 through which the cable 39 can be wired is formed. At the center of the inner surface of the upper side wall 25 and the lower side wall 26 of the box main body 23, a wiring device mounting part 30 extending from the front ends of the upper side wall 25 and the lower side wall 26 toward the bottom plate 24 is integrally formed. A mounting hole 30a is formed on the front surface. Further, as shown in FIG. 4, the mounting hole 30a faces the front opening of the box body 23, and a female screw capable of being screwed with the male screw of the fixing screw 11 is screwed into the inner periphery of each wiring device mounting portion 30. An engraved female screw portion 30b is formed.

左側壁２７には長孔状のビス孔３１が所定間隔をおいて３箇所に貫通形成され、前記柱２２に対して前記ビス孔３１からビス３２を固定することにより、配線用ボックス２０をその柱２２に取り付けることができるようになっている。図３に示すように、底板２４の上部の一側部には３箇所に保持突起３３が一定間隔をおいて突設され、隣接する保持突起３３の間に固定用ビス１１の軸部１１ａを保持可能になっている。そして、前記保持突起３３による軸部１１ａの保持によりボックス本体２３の底板２４上に２本の固定用ビス１１を保持して、前記構成の固定用ビス１１を備えた配線用ボックス２０が構成されるようになっている。図６に示すように、配線用ボックス２０に保持される固定用ビス１１の軸部１１ａの軸線方向への長さＬ１はボックス本体２３の厚みＴ１より長く形成されている。 In the left side wall 27, elongated hole-shaped screw holes 31 are formed at three positions with predetermined intervals. By fixing the screws 32 from the screw holes 31 to the pillars 22, the wiring box 20 can be It can be attached to the pillar 22. As shown in FIG. 3, holding projections 33 are protruded at three positions on one side of the upper portion of the bottom plate 24, and the shaft portion 11 a of the fixing screw 11 is inserted between the adjacent holding projections 33. It can be held. Then, by holding the shaft portion 11a by the holding projection 33, the two fixing screws 11 are held on the bottom plate 24 of the box body 23, and the wiring box 20 having the fixing screw 11 having the above-described configuration is formed. It has become so. As shown in FIG. 6, a length L <b> 1 in the axial direction of the shaft portion 11 a of the fixing screw 11 held in the wiring box 20 is longer than a thickness T <b> 1 of the box body 23.

また、第１折取溝１２ａ又は第２折取溝１２ｂから軸部１１ａを折り取ることにより得られる固定用ビス１１の軸部１１ａの軸線方向への長さＬ２又はＬ３はそれぞれボックス本体２３の厚みＴ１より短くなっている。 Further, the length L2 or L3 in the axial direction of the shaft portion 11a of the fixing screw 11 obtained by breaking the shaft portion 11a from the first breakage groove 12a or the second breakage groove 12b is respectively determined by the box body 23. It is shorter than the thickness T1.

図５に示すように、配線用ボックス２０の前面に配置される配線器具保持枠３４は略四角枠状をなし、その中央部に配線器具３５を保持することができるようになっている。また、配線器具保持枠３４の上下両端部には孔３４ａが形成され、各孔３４ａから前記取付孔３０ａに固定用ビス１１を挿通可能になっている。そして、図９に示すように、各固定用ビス１１の雄ねじを前記雌ねじ部３０ｂに螺合すると、配線器具保持枠３４を介して配線器具３５をボックス本体２３、即ち配線用ボックス２０に取付けることができるとともに、壁２１に配線器具３５を取り付けることができる。 As shown in FIG. 5, the wiring device holding frame 34 disposed on the front surface of the wiring box 20 has a substantially square frame shape, and the wiring device 35 can be held at the center thereof. Further, holes 34a are formed at both upper and lower ends of the wiring device holding frame 34, and the fixing screws 11 can be inserted from the holes 34a into the mounting holes 30a. Then, as shown in FIG. 9, when the male screw of each fixing screw 11 is screwed into the female screw portion 30 b, the wiring device 35 is attached to the box body 23, that is, the wiring box 20 via the wiring device holding frame 34. In addition, the wiring device 35 can be attached to the wall 21.

前記固定用ビス１１の使用方法について以下に記載する。
まず、図４に示すように、柱２２に対して配線用ボックス２０を取り付け、その配線用ボックス２０内にケーブル３９を配線する。次いで、図５に示すように、配線用ボックス２０の前面に他方の壁材２１ｂを設置して配線用ボックス２０を一対の壁材２１ａ、２１ｂの間に配置するとともに、壁２１を形成する。続いて、配線用ボックス２０の前面開口が他方の壁材２１ｂの表側に臨むように貫通孔３６を形成し、その貫通孔３６から配線用ボックス２０内のケーブル３９を壁２１の表側へ引き出す。そのケーブル３９に配線器具３５を接続し、その配線器具３５を配線器具保持枠３４に保持させる。 A method of using the fixing screw 11 will be described below.
First, as shown in FIG. 4, the wiring box 20 is attached to the pillar 22, and the cable 39 is wired in the wiring box 20. Next, as shown in FIG. 5, the other wall member 21 b is installed on the front surface of the wiring box 20, the wiring box 20 is disposed between the pair of wall members 21 a and 21 b, and the wall 21 is formed. Subsequently, a through hole 36 is formed so that the front opening of the wiring box 20 faces the front side of the other wall member 21 b, and the cable 39 in the wiring box 20 is drawn out from the through hole 36 to the front side of the wall 21. A wiring device 35 is connected to the cable 39, and the wiring device 35 is held by the wiring device holding frame 34.

次いで、配線用ボックス２０の底板２４に保持された固定用ビス１１をそれぞれ保持突起３３間から取外す。図６に２点鎖線で示すように、固定用ビス１１の軸部１１ａの軸線方向への長さＬ１は配線用ボックス２０の厚みＴ１より長く形成され、固定用ビス１１をそのまま使用すると配線用ボックス２０の裏側の壁材２１ａに当たってしまう。そのため、軸部１１ａの軸線方向への長さＬ１を調整する。 Next, the fixing screws 11 held on the bottom plate 24 of the wiring box 20 are respectively removed from between the holding projections 33. As shown by a two-dot chain line in FIG. 6, the axial length L1 of the shaft portion 11a of the fixing screw 11 is formed longer than the thickness T1 of the wiring box 20, and if the fixing screw 11 is used as it is, it is for wiring. It hits the wall material 21 a on the back side of the box 20. Therefore, the length L1 in the axial direction of the shaft portion 11a is adjusted.

まず、図２（ｂ）に示すように、一方の分割体１３ａにおいて、第２収容孔１７に固定用ビス１１の頭部１１ｂを収容するとともに、収容溝１５内に軸部１１ａを収容する。このとき、第２折取溝１２ｂにおいて、頭部１１ｂ側端縁が分割体１３ａの一端縁に位置する。次いで、他方の分割体１３ｂを一方の分割体１３ａ上に配置し、各ねじ孔１８にねじ１９を螺合する。すると、図７に示すように、一対の分割体１３ａ、１３ｂにより保持部１４及び溝部１４ａが形成されて折取具１３が構成される。その折取具１３の溝部１４ａに固定用ビス１１の頭部１１ｂ及び第２折取溝１２ｂより頭部１１ｂ側が収容されるとともに、保持部１４により固定用ビス１１が保持される。それと同時に、折取具１３の一端縁より外方には第２折取溝１２ｂより先端側の軸部１１ａが露出する。 First, as shown in FIG. 2B, in one divided body 13 a, the head 11 b of the fixing screw 11 is accommodated in the second accommodation hole 17, and the shaft portion 11 a is accommodated in the accommodation groove 15. At this time, in the 2nd cut-off groove 12b, the head 11b side edge is located in the one end edge of the division body 13a. Next, the other divided body 13 b is disposed on the one divided body 13 a, and the screw 19 is screwed into each screw hole 18. Then, as shown in FIG. 7, the holding part 14 and the groove part 14a are formed by a pair of division body 13a, 13b, and the breaker 13 is comprised. The head portion 11 b side of the fixing screw 11 is accommodated in the groove portion 14 a of the breaker 13 and the fixing screw 11 is held by the holding portion 14. At the same time, the shaft portion 11a on the distal end side of the second break groove 12b is exposed outward from one end edge of the breaker 13.

続いて、折取具１３の他端側を手で把持するとともに、図示しないプライヤーにより軸部１１ａを把持し、折取具１３の一端縁を支点にし、てこの原理を利用して軸部１１ａの先端側を図７に矢印で示す方向へ折り曲げる。このとき、固定用ビス１１は一対の分割体１３ａ、１３ｂにより挟持されるとともに、軸部１１ａの断面形状に対応する断面円形状の溝部１４ａ内に収容されている。加えて、ねじ１９により一対の分割体１３ａ、１３ｂが締め付けられている。そのため、軸部１１ａの折り曲げの際に、一対の分割体１３ａ、１３ｂの分離が防止されるとともに、軸部１１ａが保持部１４に保持されて折取具１３内を移動するのが防止される。すると、第２折取溝１２ｂはその他の部分より細く形成されているため、その第２折取溝１２ｂより軸部１１ａの先端側が折り取られる。 Subsequently, the other end side of the breaker 13 is gripped by hand, the shaft portion 11a is gripped by a pliers (not shown), and one end edge of the breaker 13 is used as a fulcrum. Is bent in the direction indicated by the arrow in FIG. At this time, the fixing screw 11 is sandwiched between the pair of divided bodies 13a and 13b and is accommodated in a groove portion 14a having a circular cross section corresponding to the cross sectional shape of the shaft portion 11a. In addition, the pair of divided bodies 13 a and 13 b are fastened by screws 19. Therefore, when the shaft portion 11a is bent, the pair of divided bodies 13a and 13b are prevented from being separated, and the shaft portion 11a is prevented from being moved by the holding portion 14 and moving inside the folding tool 13. . Then, since the 2nd breaking groove 12b is formed more narrowly than the other part, the front end side of shaft part 11a is broken off from the 2nd breaking groove 12b.

その後、図８に示すように、各ねじ孔１８からねじ１９を螺退するとともに、一対の分割体１３ａ、１３ｂを分解して固定用ビス１１を取り出す。その結果、図８に２点鎖線で示すように、第２折取溝１２ｂより先端側の軸部１１ａが折り取られる。そして、折り取られた分だけ軸部１１ａの軸線方向への長さが短く形成され、軸部１１ａの軸線方向への長さがＬ３に設定された固定用ビス１１が得られる。この作業を他方の固定用ビス１１に対しても同様に行う。 Thereafter, as shown in FIG. 8, the screw 19 is screwed out from each screw hole 18, and the pair of divided bodies 13 a and 13 b are disassembled to take out the fixing screw 11. As a result, as shown by a two-dot chain line in FIG. 8, the shaft portion 11a on the tip side from the second break groove 12b is broken. And the length to the axial direction of the axial part 11a is formed short by the part to which it broke off, and the fixing screw 11 by which the length to the axial direction of the axial part 11a was set to L3 is obtained. This operation is similarly performed on the other fixing screw 11.

そして、図９に示すように、配線器具保持枠３４の各孔３４ａから配線器具取付部３０の雌ねじ部３０ｂに固定用ビス１１の雄ねじを螺合する。このとき、軸部１１ａの雄ねじの雌ねじ部３０ｂに対する螺進量は、軸部１１ａを折り取る前の固定用ビス１１と比較して少なくなっている。その結果、壁２１の表側に配線器具保持枠３４が取り付けられ、配線器具３５が壁２１の表側に取り付けられる。また、固定用ビス１１は軸部１１ａが折り取られているため、軸部１１ａの軸線方向への長さＬ３が配線用ボックス２０の厚みＴ１より短くなり、固定用ビス１１が配線用ボックス２０の底板２４から突出するのが防止される。 Then, as shown in FIG. 9, the male screw of the fixing screw 11 is screwed into the female screw portion 30 b of the wiring device attachment portion 30 from each hole 34 a of the wiring device holding frame 34. At this time, the screwing amount of the male screw of the shaft portion 11a with respect to the female screw portion 30b is smaller than that of the fixing screw 11 before the shaft portion 11a is broken. As a result, the wiring device holding frame 34 is attached to the front side of the wall 21, and the wiring device 35 is attached to the front side of the wall 21. In addition, since the fixing screw 11 has the shaft portion 11a broken off, the axial length L3 of the shaft portion 11a is shorter than the thickness T1 of the wiring box 20 and the fixing screw 11 is connected to the wiring box 20. Protruding from the bottom plate 24 is prevented.

前記の実施形態によって発揮される効果について、以下に記載する。
（１）第２折取溝１２ｂから軸部１１ａの先端側を折り取ることにより、折り取り前の軸部１１ａの軸線方向への長さＬ１を容易に短くすることができる。
従って、軸部１１ａを折り取る前の固定用ビス１１と異なり、固定用ビス１１の雄ねじを雌ねじ部３０ｂに螺進する量を減らすことができ、配線器具保持枠３４を介した配線器具３５の壁２１に対する取付作業の簡易化を図ることができる。 The effects exhibited by the above embodiment will be described below.
(1) The length L1 in the axial direction of the shaft portion 11a before being broken can be easily shortened by folding the tip end side of the shaft portion 11a from the second folding groove 12b.
Therefore, unlike the fixing screw 11 before the shaft portion 11a is broken, the amount of the male screw of the fixing screw 11 screwed into the female screw portion 30b can be reduced, and the wiring device 35 via the wiring device holding frame 34 can be reduced. Simplification of the attachment work to the wall 21 can be achieved.

（２）第１折取溝１２ａ又は第２折取溝１２ｂから軸部１１ａの先端側を折り取ることにより軸部１１ａの軸線方向への長さをＬ２又はＬ３にして、軸部１１ａの軸線方向への長さを配線用ボックス２０の厚みＴ１より短くすることができる。そのため、固定用ビス１１を使用して配線器具保持枠３４を配線用ボックス２０に取り付けたとき、固定用ビス１１が底板２４の背面側へ突出して一方の壁材２１ａに当たるのを防止することができる。従って、固定用ビス１１が壁２１内に収まらなくなり、配線用ボックス２０を使用して配線器具３５を壁２１に取り付けることができなくなるという不具合をなくすことができる。 (2) The length of the shaft portion 11a in the axial direction is set to L2 or L3 by breaking the tip end side of the shaft portion 11a from the first break groove 12a or the second break groove 12b, and the axis of the shaft portion 11a The length in the direction can be made shorter than the thickness T1 of the wiring box 20. Therefore, when the wiring device holding frame 34 is attached to the wiring box 20 using the fixing screw 11, it is possible to prevent the fixing screw 11 from protruding toward the back side of the bottom plate 24 and hitting one wall member 21 a. it can. Accordingly, it is possible to eliminate the problem that the fixing screw 11 cannot be accommodated in the wall 21 and the wiring device 35 cannot be attached to the wall 21 using the wiring box 20.

（３）各折取溝１２ａ、１２ｂは軸部１１ａの中心線に向かうに従い細くなるように断面Ｖ溝状に形成されている。そのため、各折取溝１２ａ、１２ｂが断面コ字状をなすように形成されている場合と比較して各折取溝１２ａ、１２ｂから軸部１１ａを容易に折り取ることができる。 (3) Each of the cut-off grooves 12a and 12b is formed in a V-shaped cross section so as to become narrower toward the center line of the shaft portion 11a. Therefore, the shaft portion 11a can be easily folded from the respective folding grooves 12a and 12b as compared with the case where the respective folding grooves 12a and 12b are formed to have a U-shaped cross section.

（４）軸部１１ａには第１及び第２折取溝１２ａ、１２ｂが形成されているため、他方の壁材２１ｂの厚みに対応させて軸部１１ａの軸線方向への長さを変更することができる。従って、折取不能の固定用ビスが配線用ボックス２０に備え付けられている場合と異なり、３種類の他方の壁材２１ｂの厚みに対応することができる。従って、軸部１１ａの軸線方向への長さＬ１が複数種類に設定された固定用ビスを別途用意する手間を省くことができる。また、固定用ビス１１の雄ねじを雌ねじ部３０ｂに螺進する量を多くならないようにして配線器具３５の取付作業の簡易化を図ることができる。 (4) Since the shaft portion 11a has the first and second cut-off grooves 12a and 12b, the length of the shaft portion 11a in the axial direction is changed in accordance with the thickness of the other wall member 21b. be able to. Therefore, unlike the case where the fixing screw that cannot be broken off is provided in the wiring box 20, it is possible to cope with the thicknesses of the other three types of wall members 21b. Therefore, it is possible to save the trouble of separately preparing fixing screws in which the length L1 of the shaft portion 11a in the axial direction is set to a plurality of types. Further, the mounting work of the wiring device 35 can be simplified by not increasing the amount by which the male screw of the fixing screw 11 is screwed into the female screw portion 30b.

（５）固定用ビス１１は壁２１内に設置された配線用ボックス２０に予め保持されているため、配線器具３５の取付時に固定用ビス１１を別途用意する必要がなく、配線器具３５の取付作業の迅速化を図ることができる。 (5) Since the fixing screw 11 is held in advance in the wiring box 20 installed in the wall 21, it is not necessary to prepare the fixing screw 11 separately when the wiring device 35 is attached. Work can be speeded up.

（６）固定用ビス１１の各折取溝１２ａ、１２ｂからの折り取り作業は折取具１３を使用して行われる。そのため、固定用ビス１１の折り取り作業を手で行う場合と異なり、折り取り作業の簡易化を図ることができる。 (6) The folding operation of the fixing screw 11 from the respective folding grooves 12 a and 12 b is performed using the folding tool 13. Therefore, unlike the case where the fixing work of the fixing screw 11 is performed by hand, the folding work can be simplified.

（７）一対の分割体１３ａ、１３ｂにより固定用ビス１１を挟持するため、軸部１１ａの折り取り作業中に軸部１１ａが折取具１３から抜け出るのを防止して折り取り作業の簡易化を図ることができる。 (7) Since the fixing screw 11 is sandwiched between the pair of divided bodies 13a and 13b, the shaft portion 11a is prevented from being pulled out of the folding tool 13 during the shaft portion 11a folding operation, thereby simplifying the folding operation. Can be achieved.

（８）固定用ビス１１を保持した一対の分割体１３ａ、１３ｂはねじ１９により締め付けられるため、軸部１１ａを折り取ろうとしたとき一対の分割体１３ａ、１３ｂが分離するのを防止することができる。従って、固定用ビス１１を溝部１４ａ内に確実に保持して軸部１１ａの折り取り作業を確実に行うことができる。 (8) Since the pair of divided bodies 13a and 13b holding the fixing screws 11 are fastened by the screws 19, it is possible to prevent the pair of divided bodies 13a and 13b from separating when attempting to break off the shaft portion 11a. it can. Therefore, the fixing screw 11 can be reliably held in the groove portion 14a, and the shaft portion 11a can be reliably folded.

（９）溝部１４ａは断面円形状をなす軸部１１ａに対応する断面円形状をなすため、軸部１１ａを溝部１４ａ内に安定した状態で保持することができる。
（１０）溝部１４ａに固定用ビス１１を収容して保持部１４に保持させたとき、第１又は第２折取溝１２ａ、１２ｂの頭部１１ｂ側端縁が折取具１３の一端縁に位置するように形成されている。そのため、一体の折取具１３を使用して第１折取溝１２ａ又は第２折取溝１２ｂからも軸部１１ａを容易に折り取ることができ、各折取溝１２ａ、１２ｂに対応した折取具１３を別々に用意する場合と異なり折り取り作業の簡易化を図ることができる。 (9) Since the groove portion 14a has a circular cross section corresponding to the shaft portion 11a having a circular cross section, the shaft portion 11a can be stably held in the groove portion 14a.
(10) When the fixing screw 11 is accommodated in the groove portion 14 a and is held by the holding portion 14, the edge of the first or second cut-off groove 12 a, 12 b on the head 11 b side is at one end edge of the breaker 13. It is formed to be located. Therefore, the shaft portion 11a can be easily broken from the first breakage groove 12a or the second breakage groove 12b using the integral breaker 13, and the breakage corresponding to each breakage groove 12a, 12b can be made. Unlike the case where the handle 13 is prepared separately, the folding work can be simplified.

（１１）保持部１４は固定用ビス１１の軸部１１ａと頭部１１ｂを保持可能に形成されている。そのため、保持部１４により固定用ビス１１を保持し、軸部１１ａを折り取ろうとしたとき固定用ビス１１が溝部１４ａ内で移動するのを防止して軸部１１ａの折り取り作業を容易に行うことができる。 (11) The holding portion 14 is formed so as to hold the shaft portion 11a and the head portion 11b of the fixing screw 11. For this reason, the fixing screw 11 is held by the holding portion 14, and when the shaft portion 11a is to be broken, the fixing screw 11 is prevented from moving in the groove portion 14a, and the shaft portion 11a is easily broken off. be able to.

（１２）折取具１３の他端側を把持し、一端縁を支点にして軸部１１ａの先端側を折り曲げるため、てこの原理により軸部１１ａを容易に折り曲げることができ、軸部１１ａの折り取り作業を容易に行うことができる。 (12) Since the other end side of the breaker 13 is gripped and the distal end side of the shaft portion 11a is bent using one end edge as a fulcrum, the shaft portion 11a can be easily bent by the lever principle. The folding work can be easily performed.

なお、本実施形態は、次のように変更して具体化することも可能である。
・固定用ビス１１を折取具１３を使用しないで第１又は第２折取溝１２ａ、１２ｂから折り取ってもよい。 In addition, this embodiment can also be changed and embodied as follows.
The fixing screw 11 may be broken off from the first or second breaking groove 12a, 12b without using the folding tool 13.

・図１０に示すように、折取具１３は、その厚みが固定用ビス１１の頭部１１ｂの直径より大きくなるように直方体状に形成され、その折取具１３の一端側の上面からは、頭部１１ｂの直径より深い溝部１４ａが凹設されているとともに、溝部１４ａには第１及び第２収容孔１６，１７が形成されている。さらに、折取具１３は、その上方から溝部１４ａ及び第１又は第２収容孔１６，１７に固定用ビス１１の軸部１１ａ及び頭部１１ｂを収容したとき、各折取溝１２ａ、１２ｂが、折取具１３の一端縁に位置するように形成されている。折取具１３の他端側には手で把持可能な把持部３７が形成され、その把持部３７の上面にはカッターナイフの刃部を折り取り可能とするため、前記刃部を保持可能な保持溝４０が形成されている。 As shown in FIG. 10, the breaker 13 is formed in a rectangular parallelepiped shape so that its thickness is larger than the diameter of the head 11 b of the fixing screw 11, and from the upper surface on one end side of the breaker 13. A groove 14a deeper than the diameter of the head 11b is recessed, and first and second accommodation holes 16 and 17 are formed in the groove 14a. Furthermore, when the breaker 13 accommodates the shaft part 11a and the head part 11b of the fixing screw 11 in the groove part 14a and the first or second accommodation holes 16, 17 from above, the breaker grooves 12a, 12b The folding tool 13 is formed so as to be positioned at one end edge. A grip part 37 that can be gripped by hand is formed on the other end side of the breaker 13, and the blade part of the cutter knife can be folded on the upper surface of the grip part 37 so that the blade part can be held. A holding groove 40 is formed.

そして、図１０に示す折取具１３の使用の際は、まず、図１０に２点鎖線で示すように、折取具１３の上方から溝部１４ａ及び第１又は第２収容孔１６，１７に固定用ビス１１の軸部１１ａ及び頭部１１ｂを収容する。次いで、図１０に矢印で示すように、軸部１１ａの先端側を固定用ビス１１の溝部１４ａに対する収容方向と直交する方向、即ち溝部１４ａのいずれか一方の内側壁側へ折り曲げる。すると、溝部１４ａの内側壁を支点として第１折取溝１２ａ又は第２折取溝１２ｂから軸部１１ａを容易に折り取ることができる。軸部１１ａを溝部１４ａの内側壁方向へ折り曲げるため、固定用ビス１１が溝部１４ａから上方へ抜け出るのを防止して、軸部１１ａの折り取り作業を効率良く行うことができる。 When using the breaker 13 shown in FIG. 10, first, as shown by a two-dot chain line in FIG. 10, the groove 14a and the first or second accommodation holes 16, 17 are formed from above the breaker 13. The shaft portion 11a and the head portion 11b of the fixing screw 11 are accommodated.
