Description

本発明は、天井等から吊り下げられた吊りボルトに照明器具等の固定体を固定するときに用いられる吊りボルトへの取着具に関するものである。 TECHNICAL FIELD The present invention relates to a fixture for a hanging bolt used when fixing a fixture such as a lighting fixture to a hanging bolt suspended from a ceiling or the like.

天井等から吊り下げられた吊りボルトに照明器具あるいはこれを支持するための支持金具等の固定体を取付固定するときは、高所作業となることが多い。高所作業では、脚立、梯子等を使用しての作業となるので、上り下りの回数を減らすべく一度に固定体、取付具など多くの部材等を抱えて上がることがある。その際、多くの部材等を片手で持ちながら他方の手で取り付けを行なうことは作業しにくかったり困難であるので、吊りボルトに仮保持具を取り付け、一時的に部材等の一部を仮保持して固定体の固定作業を行なうことが多い。 BACKGROUND ART When attaching and fixing a lighting fixture or a fixed body such as a support fitting for supporting the lighting fixture to a hanging bolt suspended from a ceiling or the like, work is often done at height. When working at heights, you will need to use stepladders, ladders, etc., so in order to reduce the number of times you have to go up and down, you may have to carry many parts such as fixed objects and fixtures at once. At that time, it may be difficult or difficult to hold many parts with one hand and attach them with the other hand, so attach temporary holders to the hanging bolts to temporarily hold some of the parts. The work of fixing the fixed body is often done by

特許文献１には、吊りボルトを挟持自在な２枚の挟持片を相対向させた一端と、対向する２つの取っ手を有する他端と、から成る仮保持具が開示されている。この仮保持具を用いて吊りボルトに照明器具を取り付けるときは、照明器具の本体の穴に吊りボルトを通してから、照明器具の本体の下面から突出している吊りボルトの下端側に仮保持具を取り付け、照明器具を支持させる。この状態でナットやワッシャーを仮保持具の下に突出している吊りボルトに下方から嵌めることができるので、吊りボルトにナット等を嵌め、ナットを締め付けながら仮保持具を外して照明器具の本体を吊りボルトに本固定することができる。 Patent Document 1 discloses a temporary holder that includes one end in which two opposing clamping pieces capable of clamping a hanging bolt are opposed to each other, and the other end has two opposing handles. When attaching a lighting fixture to a hanging bolt using this temporary holder, first pass the hanging bolt through the hole in the lighting fixture's body, and then attach the temporary holder to the lower end of the hanging bolt that protrudes from the bottom of the lighting fixture's body. , to support lighting equipment. In this state, nuts and washers can be fitted from below to the hanging bolts protruding below the temporary holder, so fit the nuts, etc. to the hanging bolts, remove the temporary holder while tightening the nuts, and remove the main body of the lighting fixture. It can be fixed to the hanging bolt.

取着具は、天井等から吊り下げられた吊りボルトに取着されて、吊りボルトに固定される照明器具等の固定体を固定するときに用いられ、固定体を一時的に仮保持するものである。 DESCRIPTION OF THE PREFERRED EMBODIMENTS An attachment to a hanging bolt according to an embodiment of the present invention will be described below with reference to the drawings.
A fixture is a device that is attached to a hanging bolt suspended from the ceiling, etc., and is used to secure a fixed object such as a lighting fixture that is fixed to the hanging bolt, and temporarily holds the fixed object. It is.

図１乃至図３において、取着具１は、一端側に、間に配置された吊りボルト３０の対向する両側部を挟持する一対の挟持部１０，１０を有し、他端側に、各一対の挟持部１０，１０の先端１１，１１を離間操作するための操作部２０，２０が設けられた一対の挟持体２，２と、一対の挟持部１０，１０を一定方向に付勢する付勢手段と、を備えている。一対の挟持体２，２は、一対の挟持部１０，１０の各先端１１が、吊りボルト３０を挟持する位置に受け入れるべく通過可能に開いた開位置と、閉じた閉位置と、に移動可能に軸部３に連結されている。付勢手段は、コイルばね４からなり、一対の挟持部１０，１０を閉位置に向けて付勢している。一対の挟持部１０，１０は、大径吊りボルト３１と小径吊りボルト３２との二つの径の異なる吊りボルト３０に対応すべく、大径吊りボルト用挟持部１３と小径吊りボルト用挟持部１４とが、吊りボルト３０の受け入れ方向に並列して設けられている。 In FIGS. 1 to 3, the fixture 1 has a pair of clamping parts 10, 10 on one end side that clamps opposing both sides of a hanging bolt 30 disposed therebetween, and a pair of clamping parts 10, 10 on the other end side, which clamp the opposing sides of a hanging bolt 30 disposed therebetween. A pair of clamping bodies 2, 2 provided with operation parts 20, 20 for separating the tips 11, 11 of the pair of clamping parts 10, 10, and urging the pair of clamping parts 10, 10 in a certain direction. A biasing means is provided. The pair of clamping bodies 2, 2 are movable between an open position in which the tips 11 of the pair of clamping parts 10, 10 are open so that the hanging bolts 30 can be passed through in order to receive them in the clamping position, and a closed position in which they are closed. is connected to the shaft portion 3. The biasing means includes a coil spring 4, and biases the pair of clamping parts 10, 10 toward the closed position. A pair of clamping parts 10, 10 are provided with a clamping part 13 for a large-diameter suspension bolt and a clamping part 14 for a small-diameter suspension bolt, in order to accommodate suspension bolts 30 having two different diameters, a large-diameter suspension bolt 31 and a small-diameter suspension bolt 32. are provided in parallel in the receiving direction of the hanging bolt 30.

一対の挟持体２，２は、図３に示すように形成され、略左右対称形をなしている。各挟持体２の挟持部１０は、吊りボルト３０の軸方向に間隔をあけて、図３(a)に示す一方の挟持体２では３層の挟持片１２が形成され、図３(b)に示す他方の挟持体２では４層の挟持片１２が形成されている。左右の挟持体２の各挟持片１２は、一対の挟持部１０，１０の先端１１，１１を閉じたとき、図４(b)に示すように、互いに相手の挟持片１２の間の空間に嵌り込んで交差するようになっている。各挟持片１２には大小２つの半円状に切欠された切欠孔が上下に貫通する同じ位置に形成されており、これにより、各一対の挟持部１０，１０には、大径吊りボルト用挟持部１３と小径吊りボルト用挟持部１４とが所定距離離間して独立に設けられている。大径吊りボルト用挟持部１３は大径吊りボルト３１の外径と同一の内径を有し、小径吊りボルト用挟持部１４は小径吊りボルト３２の外径と同一の内径を有していて、大小各吊りボルト３０の外面は大小各挟持部１０，１０の内壁面に全面的に当接するようになっている。 The pair of holding bodies 2, 2 are formed as shown in FIG. 3, and are substantially symmetrical. The clamping parts 10 of each clamping body 2 are spaced apart in the axial direction of the hanging bolt 30, and three layers of clamping pieces 12 are formed in one clamping body 2 shown in FIG. 3(a), and as shown in FIG. 3(b). In the other clamping body 2 shown in , four layers of clamping pieces 12 are formed. When the tips 11, 11 of the pair of clamping parts 10, 10 are closed, each clamping piece 12 of the left and right clamping bodies 2 is inserted into the space between the opposing clamping pieces 12, as shown in FIG. 4(b). They fit in and intersect. Each clamping piece 12 has two semicircular notches, large and small, formed at the same position passing through the vertically. The clamping part 13 and the clamping part 14 for small-diameter hanging bolts are provided independently at a predetermined distance apart. The large-diameter suspension bolt clamping part 13 has an inner diameter that is the same as the outer diameter of the large-diameter suspension bolt 31, and the small-diameter suspension bolt clamping part 14 has an inner diameter that is the same as the outer diameter of the small-diameter suspension bolt 32. The outer surfaces of the large and small hanging bolts 30 are brought into full contact with the inner wall surfaces of the large and small holding parts 10, 10.

一対の挟持部１０，１０において、大径吊りボルト３１を挟持する大径吊りボルト用挟持部１３は、小径吊りボルト３２を挟持する小径吊りボルト用挟持部１４よりも挟持体２の一端側である、一対の挟持部１０，１０の各先端１１側に設けられている。そして、大径吊りボルト用挟持部１３と小径吊りボルト用挟持部１４との間には、一対の挟持部１０，１０の間に突出して一対の挟持部１０，１０の間隔を狭くする配置阻害部１５が対向して一対形成されている。これにより、一対の挟持部１０，１０の先端１１，１１を最大に離間させた状態において、大径吊りボルト３１を小径吊りボルト用挟持部１４に配置できないようになっている。すなわち、対向する一対の配置阻害部１５，１５の間は、小径吊りボルト３２の外径より大きく、大径吊りボルト３１の外径より小さい間隔に形成されており、大径吊りボルト３１は、一対の挟持部１０，１０間の受け入れ方向に移動させた際に大径吊りボルト用挟持部１３の位置より奥には移動させることができないようになっている。 In the pair of clamping parts 10, 10, the large-diameter suspension bolt clamping part 13 that clamps the large-diameter suspension bolt 31 is located closer to one end of the clamping body 2 than the small-diameter suspension bolt clamping part 14 that clamps the small-diameter suspension bolt 32. It is provided on each tip 11 side of a pair of clamping parts 10, 10. Between the large-diameter suspension bolt clamping part 13 and the small-diameter suspension bolt clamping part 14, there is an arrangement that protrudes between the pair of clamping parts 10, 10 and narrows the interval between the pair of clamping parts 10, 10. A pair of portions 15 are formed facing each other. This makes it impossible to arrange the large-diameter suspension bolt 31 on the small-diameter suspension bolt clamping part 14 in a state where the tips 11, 11 of the pair of clamping parts 10, 10 are maximally spaced apart. That is, the space between the pair of opposing arrangement inhibiting parts 15, 15 is larger than the outer diameter of the small-diameter hanging bolt 32 and smaller than the outer diameter of the large-diameter hanging bolt 31, and the large-diameter hanging bolt 31 is When it is moved in the receiving direction between the pair of clamping parts 10, 10, it cannot be moved further back than the position of the clamping part 13 for large diameter hanging bolt.

一対の挟持体２，２における吊りボルト３０の軸方向の両側である上面５及び下面６は、後述する指掛け部２４を除く一端側から他端側にかけた全面が平坦面に形成されている。この平坦面は、照明器具、器具の本体、器具の支持金具などの固定体４０を一時的に仮支持する支持面、後述する載置面２１として利用することができる。 The upper surface 5 and the lower surface 6 of the pair of clamping bodies 2, 2, which are both sides of the hanging bolt 30 in the axial direction, are entirely flat from one end to the other, excluding a finger hook 24, which will be described later. This flat surface can be used as a support surface that temporarily supports a fixed body 40 such as a lighting fixture, a main body of the fixture, or a support fitting for the fixture, and as a mounting surface 21 to be described later.

一対の挟持体２，２の他端側には、一対の挟持部１０，１０の先端１１，１１を離間操作するための操作部２０がそれぞれ設けられていて、各操作部２０における吊りボルト３０の軸方向の両側である上面及び下面には、吊りボルト３０に固定される固定体４０を載置し、これを仮保持するための載置面２１が形成されている。 On the other end side of the pair of clamping bodies 2, 2, operating parts 20 for separating the tips 11, 11 of the pair of clamping parts 10, 10 are provided, respectively. A mounting surface 21 for temporarily holding a fixed body 40 fixed to the hanging bolt 30 is formed on an upper surface and a lower surface on both sides in the axial direction.

加えて、挟持体２の上面５及び下面６には、図３に示すように、固定体４０を吸着保持する磁石２２が埋め込まれている。磁石２２は挟持体２の上面５及び下面６に埋め込まれた後、外面がカバー２３で覆われており、カバー２３の外面は上面５及び下面６と同一面に形成されている。 In addition, a magnet 22 that attracts and holds the fixed body 40 is embedded in the upper surface 5 and lower surface 6 of the holding body 2, as shown in FIG. After the magnet 22 is embedded in the upper surface 5 and lower surface 6 of the holding body 2, its outer surface is covered with a cover 23, and the outer surface of the cover 23 is formed on the same plane as the upper surface 5 and the lower surface 6.

更に、操作部２０の先端には、操作部２０の先端に延びる方向と交差する方向に張り出した指掛け部２４が設けられている。指掛け部２４は、操作部２０の先端の開口部周縁全体に所定長さ外方に板状に突出していて、ここに指を掛けて摘まんで操作部２０を閉じる方向に操作することができる。指掛け部２４のうち、挟持体２の上面５及び下面６より張り出した箇所は、上面あるいは下面の載置面２１に載置した固定体４０の落下防止としても作用する。 Furthermore, a finger hook 24 is provided at the tip of the operating section 20 and extends in a direction intersecting the direction extending to the tip of the operating section 20 . The finger hook 24 protrudes outward by a predetermined length from the entire periphery of the opening at the tip of the operating section 20 in a plate shape, and can be used to operate the operating section 20 in the closing direction by placing a finger thereon and pinching it. The portions of the finger hook 24 that protrude from the upper surface 5 and lower surface 6 of the holding body 2 also serve to prevent the fixed body 40 placed on the upper or lower mounting surface 21 from falling.

付勢手段であるコイルばね４は、図４に示すように、挟持体２の軸部３に取り付けられ、コイル両端の直線状の線材が一対の操作部２０，２０の各側壁７の内壁面の中間高さ部分を弾性的に押圧し、常時操作部２０を拡開方向に付勢している。 As shown in FIG. 4, the coil spring 4, which is a biasing means, is attached to the shaft portion 3 of the clamping body 2, and the straight wire rods at both ends of the coil are attached to the inner wall surface of each side wall 7 of the pair of operating portions 20, 20. The intermediate height portion of the opening is elastically pressed to constantly urge the operating section 20 in the expansion direction.

取着具１が一時的に仮取着される吊りボルト３０は、天井から吊り下げられ、本実施形態では、大径吊りボルト３１は四分ボルトであり、小径ボルトは三分ボルトである。吊りボルト３０は、少なくとも固定体４０を上下から挟んで固定するためのナットが螺着される部分は外面に雄ネジが形成されている。 The hanging bolt 30 to which the fixture 1 is temporarily attached is suspended from the ceiling, and in this embodiment, the large diameter hanging bolt 31 is a quarter bolt, and the small diameter bolt is a three quarter bolt. The hanging bolt 30 has a male thread formed on its outer surface, at least at a portion where a nut for fixing the fixing body 40 from above and below is screwed.

次に、上記のように構成された取着具１を用いて、固定体４０である照明器具を支持する支持金具４１を吊りボルト３０に固定する方法を説明する。支持金具４１は図６及び図７に示す手順に従って固定する。支持金具４１は、図８に示すように、断面略コ字状をなす左右一対の側板４２，４２と底板４３とからなる板部材で形成され、底板４３に照明器具を取り付けるための貫通孔４４が複数設けられている。支持金具４１は、２本の吊りボルト３０に跨って固定される。 Next, a method of fixing the support fitting 41 that supports the lighting fixture, which is the fixing body 40, to the hanging bolt 30 using the fixture 1 configured as described above will be described. The support fitting 41 is fixed according to the procedure shown in FIGS. 6 and 7. As shown in FIG. 8, the support fitting 41 is formed of a plate member consisting of a pair of left and right side plates 42, 42 and a bottom plate 43, each having a substantially U-shaped cross section, and a through hole 44 for attaching a lighting device to the bottom plate 43. There are several. The support fitting 41 is fixed across the two hanging bolts 30.

まず、作業者は、支持金具４１、取着具１などを持ち、支持金具４１を吊りボルト３０に固定するためのナット、必要に応じてワッシャーをポケットに入れるなどして脚立あるいは梯子に上る。一度にこれらを持って上がれば上り下りする回数を減らすことができる。脚立等に上がったら、図６(a)に示すように、２本の吊りボルト３０のそれぞれに同一高さで取着具１を取り付ける。 First, the worker climbs onto a stepladder or ladder, holding the support metal fitting 41, the fixture 1, etc., and placing a nut for fixing the support metal fitting 41 to the hanging bolt 30, and a washer if necessary, in his pocket. If you carry these things with you at once, you can reduce the number of times you have to go up and down. After climbing onto a stepladder or the like, attach the fixture 1 to each of the two hanging bolts 30 at the same height, as shown in FIG. 6(a).

次に、図６(b)に示すように、２つの取着具１に跨ってそれらの載置面２１に支持金具４１を載置し支持させる。支持金具４１が取着具１に支持された状態を図８にも示す。支持金具４１を支持させたとき、取着具１の載置面２１は指掛け部２４を除いて全体が平坦面に形成されているとともに、載置面２１には磁石２２が埋設されており、また、操作部２０の先端の周縁に外方に突出する指掛け部２４が設けられているので、支持金具４１は取着具１から容易に落下することがなく載置面２１に安定して仮保持される。続いて、図６(c)に示すように、上側ナット５０を吊りボルト３０に下端から螺着し最終固定位置まで上方に移動させる。 Next, as shown in FIG. 6(b), the support metal fittings 41 are placed and supported on the placement surfaces 21 of the two fixtures 1. FIG. 8 also shows a state in which the support fitting 41 is supported by the fixture 1. When the support fitting 41 is supported, the mounting surface 21 of the fixture 1 is entirely formed as a flat surface except for the finger hook 24, and a magnet 22 is embedded in the mounting surface 21. Furthermore, since the finger hook 24 that protrudes outward is provided on the periphery of the tip of the operation unit 20, the support bracket 41 does not easily fall from the fixture 1 and can be stably placed on the mounting surface 21. Retained. Subsequently, as shown in FIG. 6(c), the upper nut 50 is screwed onto the hanging bolt 30 from the lower end and moved upward to the final fixing position.

次に、仮保持されている支持金具４１を取着具１から取り外し、上下反転させて底板４３が上向きとなる姿勢で、貫通孔４４に吊りボルト３０の下端を差し込み、図６(d)に示すように、支持金具４１を底板４３が上側ナット５０の下面に当接するまで持ち上げる。次いで、支持金具４１を片手で保持しつつ、取着具１を片方ずつ吊りボルト３０から取り外し、吊りボルト３０の側方から支持金具４１の下側位置に取り付ける。この状態において、支持金具４１は側方及び下方に開口しており、取着具１は、図７(e)に示すように、支持金具４１の側方端部の開口から挟持部１０が水平方向に差し込まれて吊りボルト３０に取り付けられ、載置面に支持金具４１の底板４３が載置されこれを下方から支持する。これを上方から見た状態を図９にも示す。 Next, remove the temporarily held support fitting 41 from the fixture 1, turn it upside down so that the bottom plate 43 faces upward, and insert the lower end of the hanging bolt 30 into the through hole 44, as shown in FIG. 6(d). As shown, the support fitting 41 is lifted until the bottom plate 43 comes into contact with the lower surface of the upper nut 50. Next, while holding the support fitting 41 with one hand, the fixture 1 is removed from the hanging bolt 30 one by one and attached to the lower side of the supporting fitting 41 from the side of the hanging bolt 30. In this state, the support fittings 41 are opened laterally and downwardly, and the clamping part 10 of the fixture 1 is horizontally opened from the opening at the side end of the support fittings 41, as shown in FIG. 7(e). The bottom plate 43 of the support fitting 41 is placed on the mounting surface and supported from below. This is also shown in FIG. 9 when viewed from above.

続いて、挟み込む下側ナット５１を吊りボルト３０の下端から螺着し、図７(f)に示すように、取着具１の下側まで移動させる。このとき、支持金具４１は２つの取着具１で仮支持されているので、作業者は支持金具４１を片手で保持している必要はなく下側ナット５１の取り付けのみに専念してこれを回し所定高さまで移動させることができるので作業し易い。次に、図７(g)に示すように、片方ずつ取着具１を取り外し、下側ナット５１を更に上方に螺進させる。そして、両方の下側ナット５１を、既に最終固定位置に取り付けられている上側ナット５０とで挟んで締め付ければ、支持金具４１は、図７(h)に示すように、吊りボルト３０に固定される。 Subsequently, the lower nut 51 to be inserted is screwed onto the lower end of the hanging bolt 30 and moved to the lower side of the fixture 1, as shown in FIG. 7(f). At this time, since the support metal fitting 41 is temporarily supported by the two fixtures 1, the operator does not need to hold the support metal fitting 41 with one hand, and concentrates only on attaching the lower nut 51. It is easy to work because it can be turned and moved to a predetermined height. Next, as shown in FIG. 7(g), the fixture 1 is removed one by one, and the lower nut 51 is further screwed upward. Then, by tightening both lower nuts 51 with the upper nut 50 already installed at the final fixing position, the support fitting 41 is fixed to the hanging bolt 30 as shown in FIG. 7(h). be done.

なお、図６(c)の段階で、上側ナット５０は吊りボルト３０に下方から螺着して最終固定位置より少し上方の位置に配置しておき、図７(f)の段階で、下側ナット５１を吊りボルト３０に螺着し、最終固定位置に移動させて配置した後、図７(g)の段階で片方ずつ取着具１を取り外し、支持金具４１を底板４３が下側ナット５１の上面に当接するまで下げ、更に、上側ナット５０を下方に移動させて、図７(h)に示すように、最終固定位置に取り付けられている下側ナット５１とで締め付けることによって、支持金具４１を吊りボルト３０に固定することもできる。 In addition, at the stage of FIG. 6(c), the upper nut 50 is screwed onto the hanging bolt 30 from below and placed at a position slightly above the final fixing position, and at the stage of FIG. After screwing the nuts 51 onto the suspension bolts 30 and moving them to the final fixing position, remove the fixtures 1 one by one at the stage shown in FIG. By lowering the upper nut 50 until it touches the upper surface, moving the upper nut 50 downward, and tightening it with the lower nut 51 installed at the final fixing position, as shown in FIG. 41 can also be fixed to the hanging bolt 30.

また、器具あるいはこの支持金具４１等の固定体４０の吊りボルト３０への固定高さ、固定体４０や取着具１の大きさ、手による把持のし易さ、吊りボルト３０の間隔などの条件によっては、上記手順のうち、図６(a)～(d)に示した、吊りボルト３０における上側ナット５０の上方において一時的に支持金具４１を配置しこれを取着具１で仮保持する手順を省くこともできる。この場合、最初に、上側ナット５０を吊りボルト３０の所定位置に取り付けるとともに、図７(e)に示すように、上側ナット５０の下側に支持金具４１及び取着具１を配置した後、以下、図７(f)～(h)に示したと同様の手順で、吊りボルト３０に下側ナット５１を螺着し所定高さまで移動させて上側ナット５０と下側ナット５１とで支持金具４１を挟んで締め付けることにより、支持金具４１を吊りボルト３０の所定位置に固定することもできる。この場合も、取着具１は、下側ナット５１を吊りボルト３０に螺着し所定位置まで移動させる間、支持金具４１を仮支持するので、片手で支持金具４１を保持している手間を省くことができる手段として機能する。 In addition, the height of fixing the fixed body 40 such as the fixture or this support metal fitting 41 to the hanging bolt 30, the size of the fixed body 40 and the fixture 1, the ease of grasping by hand, the spacing between the hanging bolts 30, etc. Depending on the conditions, in the above procedure, the support fitting 41 may be temporarily placed above the upper nut 50 of the hanging bolt 30 and temporarily held by the fixture 1, as shown in FIGS. 6(a) to 6(d). This step can also be omitted. In this case, first, the upper nut 50 is attached to the predetermined position of the hanging bolt 30, and the support metal fitting 41 and the fixture 1 are placed below the upper nut 50, as shown in FIG. 7(e). 7(f) to (h), the lower nut 51 is screwed onto the hanging bolt 30, moved to a predetermined height, and the upper nut 50 and lower nut 51 are connected to the supporting metal fitting 41. The support fitting 41 can also be fixed to a predetermined position of the hanging bolt 30 by pinching and tightening. In this case as well, the fixture 1 temporarily supports the support metal fitting 41 while the lower nut 51 is screwed onto the hanging bolt 30 and moved to a predetermined position, so the effort of holding the support metal fitting 41 with one hand is saved. It serves as a means of saving money.

次に、本実施形態の取着具１の作用を説明する。
取着具１は、固定体４０を仮保持できるので、上側ナット５０、下側ナット５１を吊りボルト３０に螺着して所定位置まで移動させる間、固定体４０を保持している必要がなく、ナットの取付作業に専念できるので、固定体４０を保持している煩わしさから解放され、作業性が向上する。なお、このように取着具１によって固定体４０を仮保持できることにより、脚立や梯子に上り下りする回数を減らすことができる。 Next, the operation of the fixture 1 of this embodiment will be explained.
Since the fixture 1 can temporarily hold the fixed body 40, there is no need to hold the fixed body 40 while the upper nut 50 and lower nut 51 are screwed onto the hanging bolt 30 and moved to a predetermined position. Since the user can concentrate on the nut installation work, the user is freed from the trouble of holding the fixed body 40, and work efficiency is improved. In addition, by being able to temporarily hold the fixed body 40 with the fixture 1 in this way, the number of times the user has to go up and down a stepladder or a ladder can be reduced.

そして、特に、取着具１は、一対の挟持部１０，１０に、大径吊りボルト用挟持部１３と小径吊りボルト用挟持部１４とが吊りボルト３０の受け入れ方向に並列して設けられているので、径の異なる大径吊りボルト３１及び小径吊りボルト３２に対応して取り付けることができる。
加えて、大小二つの一対の挟持部１０，１０が吊りボルト３０の受け入れ方向に並列して設けられており、各一対の挟持部１０，１０は、内部空間を共有せず、それぞれ独立して形成され、径の異なる大径吊りボルト３１及び小径吊りボルト３２に対応した専用のものであるので、いずれの吊りボルト３０に対しても周縁が吊りボルト３０の外面に全体的に当接し、取着具１を吊りボルト３０に安定して保持させることができる。 In particular, the attachment 1 includes a pair of clamping parts 10, 10, and a clamping part 13 for a large-diameter suspension bolt and a clamping part 14 for a small-diameter suspension bolt, which are provided in parallel in the receiving direction of the suspension bolt 30. Therefore, it is possible to attach the large diameter suspension bolt 31 and the small diameter suspension bolt 32 which have different diameters.
In addition, a pair of clamping parts 10, 10, two large and small, are provided in parallel in the receiving direction of the hanging bolt 30, and each pair of clamping parts 10, 10 do not share an internal space, but are independent from each other. Since it is specially designed for large-diameter suspension bolts 31 and small-diameter suspension bolts 32 with different diameters, the periphery of each suspension bolt 30 contacts the entire outer surface of the suspension bolt 30, making it easy to install. The garment 1 can be stably held on the hanging bolt 30.

更に、一対の挟持部１０，１０の先端１１，１１は、閉じた状態で相互に交差するように設けられているので、取着具１の非使用時の初期姿勢から使用時の挟持姿勢に至るコイルばね４の変形量を大きくすることができる。このため、吊りボルト３０への保持力を高めることができる。 Furthermore, the tips 11, 11 of the pair of clamping parts 10, 10 are provided so as to intersect with each other in the closed state, so that the attachment tool 1 can be changed from the initial position when not in use to the clamping position when in use. The amount of deformation of the coil spring 4 can be increased. Therefore, the holding force to the hanging bolt 30 can be increased.

更に、操作部２０の先端に指掛け部２４が設けられているので、取着具１を吊りボルト３０に取着するとき、指掛け部２４に指を掛けて摘まむようにして操作でき、作業し易い。特に、非使用時には操作部２０は大きく広がっているので使用時には操作部２０を握りにくいが、指掛け部２４が設けられていることにより片手でも操作し易い。また、操作部２０を操作し易いことにより、操作部２０を広げたフリー状態にしておくことができ、非使用時に付勢手段であるコイルばね４に大きな負荷がかからないようにしておくことができる。 Furthermore, since the finger hook 24 is provided at the tip of the operating part 20, when attaching the attachment 1 to the hanging bolt 30, the operator can hook the finger hook 24 with his or her finger and pinch it to make the operation easier. In particular, since the operating section 20 is wide when not in use, it is difficult to grasp the operating section 20 when in use, but since the finger rest 24 is provided, it is easy to operate with one hand. In addition, since the operating section 20 is easy to operate, the operating section 20 can be kept in an expanded and free state, and a large load can be prevented from being applied to the coil spring 4, which is the biasing means, when not in use. .

ところで、上記実施形態の一対の挟持部１０，１０は、大径吊りボルト用挟持部１３が、小径吊りボルト用挟持部１４よりも一端側すなわち挟持部１０の先端１１側に設けられているが、逆に、小径吊りボルト用挟持部１４が、大径吊りボルト用挟持部１３よりも一端側に設けられたものであってもよい。
また、一対の挟持部１０，１０は、先端１１，１１が最大に離間させた状態において、大径吊りボルト３１が小径吊りボルト用挟持部１４に配置できないよう構成されているが、必ずしもこれに限定されるものではなく、大径吊りボルト３１が小径吊りボルト用挟持部１４に移動可能なものであってもよい。 By the way, in the pair of clamping parts 10, 10 of the above embodiment, the clamping part 13 for the large-diameter suspension bolt is provided on one end side, that is, the tip 11 side of the clamping part 10, rather than the clamping part 14 for the small-diameter suspension bolt. Conversely, the small-diameter suspension bolt clamping part 14 may be provided closer to one end than the large-diameter suspension bolt clamping part 13.
Furthermore, the pair of clamping parts 10, 10 are configured so that the large-diameter suspension bolt 31 cannot be placed in the small-diameter suspension bolt clamping part 14 when the tips 11, 11 are maximally spaced apart, but this is not necessarily the case. The present invention is not limited to this, and the large diameter hanging bolt 31 may be movable to the small diameter hanging bolt holding part 14.

更に、上記実施形態の挟持部１０は、大径吊りボルト用挟持部１３と小径吊りボルト用挟持部１４との二つが設けられているが、大きさの異なる挟持部を三つ以上設けてもよい。 Furthermore, although the clamping part 10 of the above embodiment is provided with two clamping parts 13 for large-diameter suspension bolts and clamping parts 14 for small-diameter suspension bolts, three or more clamping parts of different sizes may be provided. good.

なお、上記実施形態の一対の挟持部１０，１０は、大径吊りボルト用挟持部１３と小径吊りボルト用挟持部１４とが吊りボルト３０の受け入れ方向に並列して設けられ、これらの一対の挟持部１０，１０は、内部空間を共有せず、それぞれ独立したものであるが、必ずしもこれに限定されるものではなく、挟持部１０は、一対で挟持することにより吊りボルト３０に取着できるものであり、径の違いはある程度吸収できるので、本発明は、挟持部１０が、独立した内部空間を有せず、大小の吊りボルト３０に対して兼用できるものである場合にも適用することは可能である。 In addition, in the pair of clamping parts 10, 10 of the above embodiment, the clamping part 13 for a large-diameter suspension bolt and the clamping part 14 for a small-diameter suspension bolt are provided in parallel in the receiving direction of the suspension bolt 30. The clamping parts 10, 10 do not share an internal space and are independent from each other, but the invention is not necessarily limited to this, and the clamping parts 10 can be attached to the hanging bolt 30 by being clamped as a pair. Since the difference in diameter can be absorbed to some extent, the present invention can be applied even when the clamping part 10 does not have an independent internal space and can be used for both large and small hanging bolts 30. is possible.

そして、上記実施形態の付勢手段は、コイルばね４であり、一対の挟持部１０，１０の先端１１，１１は、閉じた状態で相互に交差するように設けられているが、付勢手段はコイルばね４でなくてもよく、また、一対の挟持部１０，１０の先端１１，１１は、閉じた状態で交差しないものであってもよい。 The biasing means in the above embodiment is the coil spring 4, and the tips 11, 11 of the pair of clamping parts 10, 10 are provided so as to cross each other in the closed state. does not need to be the coil spring 4, and the tips 11, 11 of the pair of clamping parts 10, 10 may not intersect in the closed state.

加えて、一対の挟持体２，２は、上面５及び下面６に平坦面が形成されいるが、上面５及び下面６のいずれか一方に平坦面が形成されていてもよい。また、挟持体２の上面５及び下面６のいずれも、平坦面が形成されていないものであってもよい。 In addition, although the pair of holding bodies 2, 2 have flat surfaces formed on the upper surface 5 and lower surface 6, a flat surface may be formed on either one of the upper surface 5 and the lower surface 6. Furthermore, neither the upper surface 5 nor the lower surface 6 of the holding body 2 may be formed with a flat surface.

また、操作部２０における吊りボルト３０の軸方向の両側には、吊りボルト３０に固定される固定体４０を載置するための載置面２１、及び固定体４０を吸着保持するための磁石２２が設けられているが、載置面２１及び磁石２２は、吊りボルト３０の軸方向のいずれか一方側のみに設けてもよい。あるいは、操作部２０の上面及び下面の少なくとも一方は、載置面２１、磁石２２のいずれかのみを設けてもよく、更には、載置面２１、磁石２２のいずれをも設けないものとしてもよい。 Further, on both sides of the hanging bolt 30 in the axial direction in the operating section 20, a mounting surface 21 for placing a fixed body 40 fixed to the hanging bolt 30, and a magnet 22 for holding the fixed body 40 by attraction. However, the mounting surface 21 and the magnet 22 may be provided only on one side of the hanging bolt 30 in the axial direction. Alternatively, at least one of the upper surface and the lower surface of the operation unit 20 may be provided with only either the mounting surface 21 or the magnet 22, or furthermore, neither the mounting surface 21 nor the magnet 22 may be provided. good.

加えて、操作部２０の先端の指掛け部２４は、操作部２０の先端の開口部周縁全体に設けられているが、その一部のみに設けてもよい。また、指掛け部２４は、所定長さ外方に板状に突出して形成されているが、指を掛けられるものであれば、表面に凹凸が形成された平面的なものであってもよい。更には、指掛け部２４を設けないものとしてもよい。 In addition, the finger rest 24 at the tip of the operating section 20 is provided on the entire periphery of the opening at the tip of the operating section 20, but may be provided only on a portion thereof. Further, the finger rest part 24 is formed to protrude outward by a predetermined length in the form of a plate, but may be a flat part with unevenness formed on the surface as long as the finger rest can be hung thereon. Furthermore, the finger rest portion 24 may not be provided.
