[Problems to be solved by the device]

 However, in the conventional lighting fixture mounting structure, when adjusting the level of the lighting fixture, it is necessary to adjust the bolts and nuts at each lifting point, which is troublesome and requires multiple hanging fixtures. It is difficult to get horizontal between the tools. Especially, when a large number of lighting fixtures are installed, there is a problem that enormous man-hours are required.

In addition, in the conventional mounting structure, since the lighting fixture is supported by the suspender suspended from the ceiling portion, there is a problem that the shake occurs, and a dedicated breath material or the like is used to prevent the shake. It is used. However, even in that case, the structure was complicated, and it was not strong against swaying in any of the front, back, left, and right directions, and a sufficient swaying prevention effect was not always obtained. Furthermore, such a mounting structure causes similar problems not only when mounting a lighting fixture but also when mounting other long members to a structure.

An object of the present invention is to provide a structure for mounting a long member that can easily adjust the level and can obtain a sufficient shake prevention effect.

The present embodiment is an example in which a power supply duct for a lighting device is applied as a long member, and the power supply duct is directly hung in a room of a building where the space above the ceiling is not formed. 1 and 2 show an entire mounting structure 200 for a long member according to the present embodiment. This mounting structure 200 is a beam structure made of, for example, H-shaped steel, which is a structure of a building. A pair of upper support members 1 supported on the power supply duct and separated by a predetermined distance, a pair of lower support members 2 mounted on the power supply duct 4 and separated by a predetermined distance, and an upper support member. 1 and a pair of suspension members 3 that connect the lower support member 2 to each other.

On the lower flange portion 100A of the beam 100, there is slidably attached a pair of upper support members 1 which are spaced apart from each other by a predetermined distance. These upper support members 1 are indicated by arrows A in FIG. As shown by B, they can be slid in mutually opposite directions and positioned at a predetermined position on the lower flange portion 100A. As a result, the height position of the power supply duct 4 can be adjusted, and in FIG. 1, for example, the power supply duct 4 is positioned at the position of the reference dimension L at which the reference height H from the lower surface of the beam 100 is obtained.

As shown in FIG. 2, the pair of upper supporting members 1 are provided with two fixing blocks 10, 10 which are supporting members, and these fixing blocks 10, 10 are arranged in a sliding direction with respect to the beam 100. That is, they are arranged to face each other in the direction orthogonal to the positioning direction and can engage with the lower flange portions 100A on both sides of the beam 100. As shown in FIGS. 3 and 5, the fixed blocks 10 and 10 are each formed into a substantially rectangular parallelepiped shape, and slide grooves 11 having inclined portions 11A are formed on the surfaces facing each other, and the lower flange portion 100A is formed. It is easy to engage with, and it is possible to cope with changes in the thickness of the lower flange portion 100A.

A through-hole 11B orthogonal to the groove 11 is formed in the lower part of the slide groove 11, and a tightening shaft 12 connecting the two fixing blocks 10 is inserted into the hole 11B. There is. Then, the nuts 13 are screwed into the screw parts 12A at both ends of the tightening shaft 12 and tightened, the slide groove 11 engages with the lower flange part 100A, and the two fixing blocks 10 and 10 are fixed at predetermined positions. . Here, the upper support member 1 is constituted by the two fixing blocks 10, 10, the tightening shaft 12 and the nut 13.

As shown in FIGS. 2 and 4, the pair of lower support members 2 includes a suspension ring 20 having a predetermined width in the slide direction of the upper support member 1. As shown in FIG. 6, a groove 20A having a predetermined width along the width direction is cut in the bottom portion. The power supply duct 4 is fitted in the groove 20A, both of which are relatively slidable, and can be fixed by a holding bolt 21 screwed onto the upper portion of the suspension ring 20. The power supply duct 4 is referred to as a product name fact line or a lighting rail. Predetermined electricity is sent to the power supply duct 4 through wiring (not shown), and the lighting fixture 5 can be installed at any position of the power supply duct 4. It is configured to light up when connected.

Horizontal rods 22 which are orthogonal to the width direction and are internally threaded are fixed to both sides of the suspension ring 20, and internal screws of the horizontal rods 22 are fitted with washers 26. A mounting bolt 27 is screwed on, whereby the suspension member 3 is mounted on the horizontal bar 22. A collar 23 is rotatably attached to the horizontal bar 22. As shown in FIG. 4, one support member 24A of the two support members 24 for supporting the lighting fixture 5 is integrally fixed to the lower portion of the collar 23. The other supporting member 24B is connected to the supporting member 24A by a mounting bolt and a nut 25. These supporting members 24 have a cross-sectional shape that is substantially the same when they are combined as shown in FIG. It is formed to have a semicircular shape, and each tip can support the lighting fixture 5. Here, the lower support member 2 is constituted by the suspension ring 20, the horizontal bar 22, the two support members 24, and the like.

The pair of suspending members 3 are formed to have the same length, connect the upper supporting member 1 and the lower supporting member 2 as described above, and suspend and support the power supply duct 4. The pair of suspension members 3 is composed of two suspension rods 30, each connecting the two fixed blocks 10 of the upper support member 1 and the horizontal rod 22 of the lower support member 2.

Collars 31 and 32 are fixed to the upper and lower ends of each suspension rod 30, respectively. As shown in FIG. 5, the collar 31 at one end attached to the upper support member 1 side is located outside the block 10 and is rotatably attached to the tightening shaft 12. The other end color 32 is rotatably attached to the horizontal bar 22, as shown in FIG.

Here, as shown in FIGS. 2, 5 and 6, each of the two hanging rods 30 constituting the pair of hanging members 3 is horizontal when viewed from the extension direction of the power supply duct 4 (width direction). The mounting angle is θ ° with respect to. Therefore, the two suspension rods 30, 30 are formed so that the space S1 on the suspension ring 20 side is narrower than the space S2 between the two blocks 10, 10 and the lower part is tapered. As a result, in the width direction, it is formed in a substantially triangular truss shape or an inverted trapezoidal shape.

Further, when viewed from the direction orthogonal to the paper surface in FIG. 1, each hanging rod 30 has a height position of the luminaire 5 below the beam 100 when the upper support member 1 is fixed at the position of the reference dimension L. The length is set so that the reference dimension H is obtained from the end face, and the hanging rods 30 are arranged in a substantially C-shape, and as a result, the hanging rod 30 forms a substantially triangular truss shape or a trapezoidal shape. Has been formed. As described above, since the suspension rods 30 form trusses in the longitudinal direction and the width direction with respect to the power supply duct 4, the power supply duct 4 is prevented from swinging in the longitudinal direction and the width direction. Has a strong resistance. In the space in the truss formed in the longitudinal direction, for example, an air-conditioning duct 101 may be arranged or an existing duct may be avoided.

Next, the operation of this embodiment will be described. In advance, the pair of upper support members 1 and the pair of lower support members 2 are connected by the pair of suspension members 3, and the power supply duct 4 is attached to the pair of lower support members 2 to integrally combine them.

After that, the power supply duct 4 and the like integrally combined in this way are attached to the beam 100. At this time, the slide grooves 11 of each of the two blocks 10 and 10 are engaged with the lower flange portion 100A of the beam 100, and the position of the pair of upper support members 1 is set to, for example, the reference dimension L, and the nut 13 is tightened. Bring the two blocks 10, 10 together and secure them to the beam 100. Next, the lighting fixture 5 is attached to the support member 24.

When it is desired to change the height of the lighting fixture 5, the holding bolt 21 of the suspension ring 20 and the nut 13 of the tightening shaft 12 are loosened, and the pair of upper support members 1 are used together or on one side. The upper support member 1 is slid. For example, in FIG. 1, if the pair of upper support members 1 are slid in the direction of arrow A by L1 size, the lighting fixture 5 represented by the solid line is lowered by H1 and set to the height indicated by the imaginary line. become.

According to this embodiment as described above, the following effects can be obtained. That is, the upper support member 1 and the lower support member 2 connected by the pair of suspension members 3 having the same length can be slid and fixed to the beam 100 and the power supply duct 4, respectively. Loosen the tightening of the two blocks 10 and 10 of the support member 1 and loosen the tightening of the suspension ring 20 and the power supply duct 4 of the lower support member 2 so that the two blocks 10 and 10 are either together or on one side. If you slide 10 and 10, you can change the level of the power supply duct 4. Since the relationship between the slide width and the moving height is predetermined, it is only necessary to slide the height to change, and the level of the power supply duct 4 or the lighting fixture 5 can be easily adjusted.

Further, the power supply duct 4 to which the lighting fixture 5 is attached has a truss shape or a trapezoidal shape whose longitudinal direction is formed by the hanging rod 30 and whose width direction is substantially inverted by the hanging rod 30. Since they are supported in a triangular truss shape or an inverted trapezoidal shape, each truss structure works against the shaking of the power feeding duct 4, and the shaking of the power feeding duct 4 can be sufficiently prevented.

Further, the beam 100 and the power supply duct 4 provided below the beam 100 are connected via the slanting suspension member 3, and a substantially triangular space is formed between them. In this space, for example, an air-conditioning duct 101 can be arranged or an existing duct can be avoided, which also has the effect of increasing the degree of freedom in design.

To mount the pair of upper support members 1 on the beam 100, the two blocks 10, 10 are engaged with their slide grooves 11 on the lower flange portion 100 A of the beam 100, and the nut 13 is tightened. It is enough and easy to install. Moreover, since the slide groove 11 is formed with the inclined portion 11A, the inclined portion 11A engages with the lower flange portion 100A with a small force, and at the same time, is securely fixed and the lower flange portion 100A Even if the thickness changes, it can be handled.

Further, when the pair of upper support members 1 is positioned at a predetermined position of the beam 100, it is sufficient that the blocks 10, 10 are slid to move and fixed at those positions, so that the positioning is easy. Further, each of the two hanging rods 30 constituting the pair of hanging members 3 is arranged in a substantially triangular truss shape or a trapezoidal shape in the longitudinal direction and in an inverted triangular truss shape or an inverted trapezoidal shape in the width direction, respectively. As a result, diagonal lines were formed, and there was a change in appearance, which was excellent in terms of design.

The present invention is not limited to the above-described embodiments, but includes modifications and the like within a range in which the object of the present invention can be achieved. For example, in the above-described embodiment, the lighting fixture 5 is attached to the power supply duct 4 via the support member 24 integrated with the suspension ring 20, but the present invention is not limited to this, and is represented by an imaginary line in FIG. 1, for example. Like the lighting fixture 50, it may be movably directly attached to the power supply duct 4. By doing so, there is an effect that the mounting position of the lighting fixture 50 is not limited.

In addition, in the above-described embodiment, the power supply duct 4 to which the lighting fixture 5 is attached is hung on the beam 100 of the type of building in which the ceiling space is not formed. Also available for. In this case, for example, a pair of rails may be laid on the ceiling, and the upper support member 1 may be slidably provided on the rails and fixed at a predetermined position. Even in this case, the same effect as described above can be obtained.

Furthermore, in the above-described embodiment, the pair of hanging members 3 is formed in a V shape, that is, the distance between the pair of lower supporting members 2 is wider than the distance between the pair of upper supporting members 1. However, the present invention is not limited to this, and the point is that the pair of suspension members 3 may be formed into a triangular truss shape or a trapezoidal shape. May be formed. However, the above-mentioned C-shape has advantages such as the effect of being stronger against shaking.

Further, in the above embodiment, the pair of upper support members 1 and the pair of lower support members 2 are provided so as to be slidable and fixable at predetermined positions with respect to the beam 100 and the power supply duct 4. Not limited to this, either one may be fixed at a predetermined position, and the other may be slid and fixed at a predetermined position. For example, in FIG. 1, the pair of lower support members 2 can slide with respect to the power supply duct 4 and can be fixed at a predetermined position, but the pair of upper support members can simply be fixed without sliding with respect to the beam 100. Any structure may be used. With such a structure, the pair of upper support members can be easily manufactured, but the above-described sliding effect of easy positioning of the upper support member 1 does not occur.

Further, although the power supply duct 4 is used as the elongated member in the above-described embodiment, the material is not limited to this and may be a material having an irregular shape such as a round shape or a square shape.

In addition, the specific structure, shape, and the like when implementing the present invention may be other structures and the like as long as the object of the present invention can be achieved.
