The suspension bolt 30 to which the attachment tool 1 is temporarily attached is suspended from the ceiling. In the present embodiment, the large-diameter suspension bolt 31 is a quadrant bolt and the small-diameter bolt is a 3/4 bolt. The suspension bolt 30 has a male screw formed on the outer surface at least in a portion where a nut for sandwiching and fixing the fixing body 40 from above and below is screwed.

Next, a method of fixing the support metal fitting 41 that supports the lighting fixture, which is the fixed body 40, to the suspension bolt 30 by using the attachment 1 configured as described above will be described. The support metal fitting 41 is fixed according to the procedure shown in FIGS. 6 and 7. As shown in FIG. 8, the support metal fitting 41 is formed of a plate member composed of a pair of left and right side plates 42, 42 having a substantially U-shaped cross section and a bottom plate 43, and a through hole 44 for attaching a lighting fixture to the bottom plate 43. Are provided in multiples. The support metal fitting 41 is fixed so as to straddle the two suspension bolts 30.

First, the operator holds the support metal fitting 41, the attachment tool 1, and the like, and climbs the stepladder or the ladder by putting a nut for fixing the support metal fitting 41 to the hanging bolt 30 and, if necessary, a washer in a pocket. If you bring them up at once, you can reduce the number of ups and downs. After rising to the stepladder or the like, as shown in FIG. 6A, attach the attachment 1 to each of the two hanging bolts 30 at the same height.

Next, as shown in FIG. 6B, the support metal fitting 41 is mounted and supported on the mounting surface 21 straddling the two attachments 1. FIG. 8 also shows a state in which the support metal fitting 41 is supported by the attachment tool 1. When the support metal fitting 41 is supported, the mounting surface 21 of the mounting tool 1 is formed as a flat surface as a whole except for the finger hook portion 24, and the magnet 22 is embedded in the mounting surface 21. Further, since the finger hook portion 24 projecting outward is provided on the peripheral edge of the tip of the operation portion 20, the support metal fitting 41 does not easily fall from the attachment 1 and is stably provisionally mounted on the mounting surface 21. Be retained. Subsequently, as shown in FIG. 6 (c), the upper nut 50 is screwed onto the suspension bolt 30 from the lower end and moved upward to the final fixing position.

Next, the temporarily held support metal fitting 41 is removed from the attachment 1, turned upside down, and the lower end of the hanging bolt 30 is inserted into the through hole 44 in a posture in which the bottom plate 43 faces upward. As shown, the support bracket 41 is lifted until the bottom plate 43 abuts on the lower surface of the upper nut 50. Next, while holding the support metal fitting 41 with one hand, the attachments 1 are removed from the suspension bolt 30 one by one and attached to the lower position of the support metal fitting 41 from the side of the suspension bolt 30. In this state, the support metal fitting 41 is open laterally and downward, and as shown in FIG. 7 (e), the holding portion 10 is horizontal from the opening of the lateral end portion of the support metal fitting 41. It is inserted in the direction and attached to the hanging bolt 30, and the bottom plate 43 of the support metal fitting 41 is placed on the mounting surface to support it from below. FIG. 9 also shows a state in which this is viewed from above.

Subsequently, the lower nut 51 to be sandwiched is screwed from the lower end of the suspension bolt 30 and moved to the lower side of the attachment 1 as shown in FIG. 7 (f). At this time, since the support metal fitting 41 is temporarily supported by the two attachment tools 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 the specified height. Next, as shown in FIG. 7 (g), the attachment 1 is removed one by one, and the lower nut 51 is further screwed upward. Then, if both lower nuts 51 are sandwiched between the upper nuts 50 already attached to the final fixing positions and tightened, the support metal fitting 41 is fixed to the suspension bolt 30 as shown in FIG. 7 (h). Will be done.

At the stage of FIG. 6 (c), the upper nut 50 is screwed onto the suspension bolt 30 from below and placed at a position slightly above the final fixing position, and at the stage of FIG. 7 (f), the lower side. After the nut 51 is screwed to the suspension bolt 30 and moved to the final fixing position and placed, the attachment 1 is removed one by one at the stage of FIG. 7 (g), and the support metal fitting 41 is attached to the bottom plate 43 with the lower nut 51. The support bracket is lowered until it comes into contact with the upper surface of the bolt, and the upper nut 50 is further moved downward and tightened with the lower nut 51 attached to the final fixing position as shown in FIG. 7 (h). The 41 can also be fixed to the suspension bolt 30.

Further, the fixing height of the fixture or the fixing body 40 such as the support metal fitting 41 to the hanging bolt 30, the size of the fixing body 40 and the attachment 1, the ease of gripping by hand, the spacing between the hanging bolts 30, and the like. Depending on the conditions, in the above procedure, the support bracket 41 is temporarily placed above the upper nut 50 in the suspension bolt 30 shown in FIGS. 6 (a) to 6 (d), and this is temporarily held by the attachment tool 1. You can also omit the procedure to do. In this case, first, the upper nut 50 is attached to a predetermined position of the suspension bolt 30, and the support metal fitting 41 and the attachment 1 are arranged under the upper nut 50 as shown in FIG. 7 (e). Hereinafter, in the same procedure as shown in FIGS. 7 (f) to 7 (h), the lower nut 51 is screwed onto the suspension bolt 30 and moved to a predetermined height, and the support metal fitting 41 is formed by the upper nut 50 and the lower nut 51. It is also possible to fix the support metal fitting 41 at a predetermined position of the suspension bolt 30 by sandwiching and tightening the support bracket 41. Also in this case, since the attachment tool 1 temporarily supports the support metal fitting 41 while the lower nut 51 is screwed to the suspension bolt 30 and moved to a predetermined position, it takes time and effort to hold the support metal fitting 41 with one hand. It functions as a means that can be omitted.

Next, the operation of the attachment 1 of the present embodiment will be described.
Since the attachment tool 1 can temporarily hold the fixed body 40, it is not necessary to hold the fixed body 40 while the upper nut 50 and the lower nut 51 are screwed onto the suspension bolt 30 and moved to a predetermined position. Since it is possible to concentrate on the nut mounting work, the troublesomeness of holding the fixed body 40 is released, and the workability is improved. Since the fixed body 40 can be temporarily held by the attachment tool 1 in this way, the number of times of going up and down the stepladder or the ladder can be reduced.

In particular, in the mounting tool 1, the large-diameter hanging bolt holding portion 13 and the small-diameter hanging bolt holding portion 14 are provided in parallel in the receiving direction of the hanging bolt 30 on the pair of holding portions 10 and 10.

The fitting 1 can be stably held by the hanging bolt 30.

Further, since the tips 11 and 11 of the pair of holding portions 10 and 10 are provided so as to intersect each other in a closed state, the attachment 1 can be changed from the initial posture when not in use to the holding posture when used. The amount of deformation of the coil spring 4 to reach can be increased. Therefore, the holding force on the suspension bolt 30 can be increased.

Further, since the finger hook portion 24 is provided at the tip of the operation portion 20, when the attachment 1 is attached to the hanging bolt 30, the finger hook portion 24 can be operated by hooking the finger on the finger hook portion 24, which facilitates the work. In particular, since the operation unit 20 is greatly expanded when not in use, it is difficult to grip the operation unit 20 when in use, but the provision of the finger hook portion 24 makes it easy to operate with one hand. Further, since the operation unit 20 is easy to operate, the operation unit 20 can be left in an expanded free state, and a large load can be prevented from being applied to the coil spring 4 which is an urging means when not in use. ..

By the way, in the pair of holding portions 10 and 10 of the above embodiment, the holding portion 13 for the large diameter hanging bolt is provided on one end side of the holding portion 14 for the small diameter hanging bolt, that is, on the tip 11 side of the holding portion 10.

The sandwiching portions 10 and 10 do not share an internal space and are independent of each other, but the present invention is not necessarily limited to this, and the sandwiching portions 10 can be attached to the suspension bolt 30 by sandwiching them in pairs. Since the difference in diameter can be absorbed to some extent, the present invention is also applied to the case where the sandwiching portion 10 does not have an independent internal space and can be used for both large and small hanging bolts 30. Is possible.

The urging means of the above embodiment is a coil spring 4, and the tips 11 and 11 of the pair of holding portions 10 and 10 are provided so as to intersect each other in a closed state. Does not have to be a coil spring 4, and the tips 11 and 11 of the pair of holding portions 10 and 10 may not intersect in a closed state.

In addition, although the pair of sandwiching bodies 2 and 2 have a flat surface formed on the upper surface 5 and the lower surface 6, a flat surface may be formed on either the upper surface 5 or the lower surface 6. Further, neither the upper surface 5 nor the lower surface 6 of the sandwiching body 2 may have a flat surface formed.

Further, on both sides of the suspension bolt 30 in the operation unit 20 in the axial direction, a mounting surface 21 for mounting the fixed body 40 fixed to the suspension bolt 30 and a magnet 22 for attracting and holding the fixed body 40 are attracted and held.
