[Figure 2] This is an exploded perspective view of a mounting member for a power supply unit, which is an example of an embodiment. [Figure 3] This is a cross-sectional view of the mounting portion of a mounting member, which is an example of an embodiment. [Figure 4] This block diagram shows the configuration of a lighting system, which is an example of an embodiment. [Modes for carrying out the invention]

[0009] Hereinafter, embodiments of the mounting members for the power supply device according to this disclosure will be described in detail with reference to the drawings. The embodiments described below are merely examples, and the present invention is not limited to these embodiments. Furthermore, the multiple embodiments and modifications described below, which are selectively combined, are included within the scope of this disclosure.

[0010] Figure 1 is a perspective view of a mounting member 20 of a power supply unit 10 according to an embodiment of this disclosure. Figure 1 shows a mounting member 20, which is an example of an embodiment, attached to the power supply unit 10. Figure 2 is an exploded perspective view of a mounting member 20, which is an example of an embodiment. In Figure 2, a portion of the power supply wire 50 extending from the power supply unit 10 is omitted. Hereafter, for the sake of explanation, the power supply unit 10 side will be referred to as the top and the structure 40 side as the bottom when the power supply unit 10 is attached to the structure 40.

[0011] As shown in Figures 1 and 2, the mounting member 20 is a member for attaching the power supply unit 10 to the structure 40 (see Figure 3, described later).

[0012] The power supply unit 10 is installed outside the lighting device 70 (see Figure 4, described later). The power supply unit 10 has a main body 11 and a plurality of extensions 12. The power supply unit 10 uses a power circuit to convert an AC voltage supplied from an external power source such as a commercial power supply into a predetermined DC voltage and supplies the DC voltage to the lighting device 70 via a power line 50. The main body 11 of the power supply unit 10 is a housing that houses the power circuit inside, and in this embodiment it has a substantially rectangular parallelepiped shape, but is not limited to this. By using the mounting member 20, the power supply unit 10 can be firmly fixed so as not to fall from the structure 40.

[0013] The extension portion 12 of the power supply unit 10 extends from both ends in the longitudinal direction of the main body 11 when the power supply unit 10 is viewed from the top surface of the main body 11. The extension portion 12 is a thin plate-like member having multiple through holes for screw fastening. As will be described in detail later, the extension portion 12 is fixed to the locking portion 23 of the mounting member 20 via the fixing portion 24. The extension portion 12 is, for example, a metal plate and may be formed by directly welding it to the sides of both ends in the longitudinal direction of the main body 11 when the main body 11 is viewed from the top surface, or it may be formed integrally by bending the metal plates that make up the sides of both ends in the longitudinal direction of the main body 11 outward at a 90-degree angle. Preferably, the lower surface of the extension portion 12 in the vertical direction is flush with the lower surface of the main body 11 or located below the lower surface of the main body 11. The lower surface of the vertically extending portion 12 is either flush with the lower surface of the main body portion 11 or positioned below the lower surface of the main body portion 11, thereby enabling the installation of the power supply unit 10 without the lower surface of the main body portion 11 interfering with the installation location.

[0014] The mounting member 20 comprises a base portion 21 for holding the power supply unit 10 and a plurality of mounting portions 26 for attaching to the structure 40. The base portion 21 is a frame-shaped member having a rectangular outer shape in plan view with a substantially square opening 22, and comprises a plurality of locking portions 23 and connecting portions 25 that connect the locking portions 23. The opening 22 is configured so that the main body portion 11 of the power supply unit 10 can be inserted through it, and the extension portion 12 of the power supply unit 10 is locked by the locking portions 23. In this case, the base portion 21 can hold the power supply unit 10. Since the power wire 50 of the power supply unit 10 is flexible, when inserting the main body portion 11 into the opening 22, the main body portion 11 including the power wire 50 can be inserted into the opening 22 by first inserting the main body portion 11 into the opening 22 with the power wire 50 bent, and then unbending the power wire 50.

[0015] The locking portions 23 are provided at both longitudinal ends of the base portion 21 that sandwich the opening 22, and lock the extension portions 12 of the power supply device 10 when the main body portion 11 is inserted through the opening 22. When the main body portion 11 of the power supply device 10 is inserted through the opening 22, the lower surface of the locking portion 23 is locked by contacting the upper surface of the extension portions 12 that extend from both longitudinal ends of the main body portion 11.

[0016] Multiple locking parts 23 each have a fixing part 24 for fixing the extension part 12. The fixing part 24 is a through hole for screw fastening, positioned to overlap with the through hole for screw fastening in the extension part 12 of the power supply unit 10. For the locking part 23 to fix the extension part 12 via the fixing part 24, for example, a screw 60a, a nut 60c that screws onto the screw, and a flat washer 60b placed on the seating surface of the nut 60c to prevent loosening are used. To fix the extension part 12 to the locking part 23, first, the main body 11 of the power supply unit 10 is inserted through the opening 22 of the mounting member 20. Next, with the lower surface of the locking part 23 and the upper surface of the extension part 12 in contact, the screw 60a is inserted from the extension part 12 side into the through hole formed by the overlapping of the through hole in the extension part 12 and the fixing part 24 of the locking part 23. Next, the screw 60a is held in place from the extension portion 12 side, a flat washer 60b is inserted into the threaded portion of the screw 60a protruding from the fixing portion 24 of the locking portion 23, and the extension portion 12 is fixed to the locking portion 23 by fastening it with a nut 60c from the locking portion 23 side. When the screw 60a is inserted from the extension portion 12 side, the workability is improved compared to when the screw 60a is inserted from the locking portion 23 side and fastened with a nut 60c from the extension portion 12 side.

[0017] The base portion 21 has connecting portions 25 that connect the multiple locking portions 23. The connecting portions 25 are the parts that extend in the longitudinal direction of the base portion 21 and connect the multiple locking portions 23. At least a portion of the connecting portions 25 is bent toward the structure 40. In this case, the rigidity and strength of the base portion 21 are improved compared to the case where the connecting portions 25 are not bent toward the structure 40 but are part of a metal plate arranged parallel to the structure 40.

[0018] The attachment part 26 is a member for attaching to the structure 40, and is provided at both longitudinal ends of the base part 21. The plurality of attachment parts 26 each have one or more through holes 27, and at least one of the plurality of attachment parts 26 has a plurality of through holes 27. Although details will be described later, by inserting a bolt 28 through the through hole 27 of the attachment part 26 of the attachment member 20 and fastening it with a fastening member 29, the power supply device 10 held by the attachment member 20 can be fixed to the structure 40. In the present embodiment, one attachment part 26A has one through hole 27A, and the other attachment part 26B has two through holes 27B and 27C. In this case, compared with the case where each attachment part 26 has one through hole 27, the power supply device 10 can be fixed to the structure 40 more firmly.

[0019] The attachment part 26 may be a separate member fixed to both longitudinal ends of the base part 21 by welding or the like, but from the viewpoint of strength and the like, it is preferably the same member as the base part 21 and is integrally formed. The plurality of attachment parts 26 are located on the side of the structure 40 by a predetermined dimension more than the locking part 23 in a state where the main body part 11 is inserted through the opening part 22 and the extending part 12 is locked to the locking part 23. When the locking part 23 and the extending part 12 are fixed by the fixing part 24, the head of the screw 60a protrudes below the extending part 12. By forming the attachment part 26 at a position lower than the locking part 23 by a dimension that can avoid the thickness of the extending part 12 and the height of the head of the screw 60a, the power supply device 10 can be fixed to the structure 40 without the head of the screw 60a interfering with the structure 40.

[0020] Next, referring to FIG. 3, the configuration of the attachment part 26 of the attachment member 20 for fixing the power supply device 10 to the structure 40 will be described in detail. FIG. 3 is a cross-sectional view of the attachment part 26 of the attachment member 20.

[0021] As shown in FIG. 3, the mounting portion 26 and the structure 40 are fixed by bolts 28 inserted through a plurality of through holes 27 and fastening members 29. The planar shape of the through holes 27 is not particularly limited, but in this embodiment, it has an elongated hole shape (see FIG. 2). Since the bolts 28 are inserted through the through holes 27, the width (W) of the through holes 27 in the shape of elongated holes is larger than the outer diameter of the bolts 28 and smaller than the maximum outer diameter (D) of the fastening members 29. Although it will be described in detail later, the maximum outer diameter (D) of the fastening member 29 is, for example, the diameter of the flat washer 29d. In this case, since the tightening load of the fastening member 29 is applied to the mounting portion 26, the power supply device 10 can be firmly fixed to the structure 40.

[0022] When fixing the mounting portion 26 of the mounting member 20 to an existing concrete structure or the like, for example, anchor bolts are used for the bolts 28, but it is not limited thereto. When the bolts 28 are anchor bolts, first, bolt holes 31 are drilled in the existing concrete structure using a drill or the like. Next, the bolts 28 are inserted into the bolt holes 31 and fixed with a curing agent injected into the bolt holes 31, so that the bolts 28 are fixed to the concrete structure. The bolts 28 fixed to the structure 40 are inserted through the through holes 27 and fastened with the fastening members 29, so that the mounting portion 26 of the mounting member 20 is fixed to the structure 40. It is sufficient that the diameter of the bolt holes 31 is slightly larger than the outer diameter of the bolts 28. The depth of the bolt holes 31 is such that when the bolts 28 are inserted, the threaded portions of the bolts 28 are sufficiently exposed above the upper surface of the structure 40, and it is preferable that the entire bolts 28 are within the depth below the upper surface of the power supply device 10 (see FIG. 1). In this case, the power supply device 10 can be firmly fixed to the structure 40 without the bolts 28 interfering with peripheral members or the like.

[0023] The fastening members 29 are, for example, nuts 29a and 29b, a spring washer 29c, and a flat washer 29d. The fastening members 29 are arranged by inserting the flat washer 29d, the spring washer 29c, and the nuts 29b and 29a in that order onto the bolt 28 inserted through the through hole 27. The flat washer 29d is used on the mounting part 26 side, which is the fastened member, to distribute the seating pressure on the mounting part 26 and prevent loosening due to the sinking of the seating surface. The spring washer 29c is a washer in which a part of the flat washer 29d is cut and twisted. The twisted structure provides an anti-loosening effect. The nuts 29a and 29b are two Type 1 nuts with one side chamfered, arranged so that the chamfered side is on top. After tightening nuts 29b and 29a in that order, nut 29b is rotated in the reverse direction to loosen it, bringing the upper surface of nut 29b and the lower surface of nut 29a into close contact. This generates friction on the threaded contact surfaces of the bolt 28 and nuts 29a and 29b, maintaining the tightening load of the fastening member 29 and thus preventing loosening of the fasteners.

[0024] A fastening member 29 used in at least one of the multiple through holes 27 is screwed onto a bolt 28 via a spacer 30. The spacer 30 is a cylindrical member having a hollow portion in radial cross-sectional view, and its material is not particularly limited, but it is preferably made of metal from the viewpoint of durability. The spacer 30 can be inserted into the through hole 27, the inner diameter of the spacer 30 is larger than the outer diameter of the bolt 28 and smaller than the outermost diameter (D) of the fastening member 29, and the thickness of the spacer 30 is greater than the mounting portion 26. In other words, the bolt 28 can be inserted into the spacer 30, the lower surface of the spacer 30 abuts against the structure 40, and the upper surface of the spacer 30 abuts against the lower surface of the fastening member 29. In this case, the fastening load by the fastening member 29 is not applied to the mounting portion 26, but to the structure 40.

[0025] Even when the mounting portion 26 is fixed to the structure 40 using bolts 28 and fastening members 29, the bolts 28 may break due to deterioration or damage, or the fastening members 29 may loosen. The mounting member 20 has multiple mounting portions 26, each of which has one or more through holes 27, and at least one of which has multiple through holes 27. In other words, at least three places on the mounting member 20 are fixed by bolts 28 and fastening members 29.

[0026] In this embodiment, when fixing the mounting member 20 to the structure 40, the mounting portion 26 and bolt 28 are designated as mounting portion 26A and bolt 28A, and mounting portion 26B and bolts 28B, 28C, respectively (see Figure 2). At mounting portion 26A, bolt 28A is screwed into the fastening member 29. At mounting portion 26B, bolt 28B is screwed into the fastening member 29. Bolt 28C is screwed into the fastening member 29 via a spacer 30, and the spacer 30 is in contact with the structure 40. In other words, mounting portion 26B is fixed to the structure 40 by bolt 28B and fastening member 29, but bolt 28C and fastening member 29 do not have the effect of fixing mounting portion 26B to the structure 40.

[0027] If, for example, bolt 28A breaks or the fastening member 29 that screws into bolt 28A comes loose, the fastening at mounting portion 26A cannot be maintained. In this case, since mounting portion 26B is fixed to the structure 40 while mounting portion 26A is not, mounting portion 26A will be floating away from the structure 40, and this will be visually recognized as an abnormality during inspection. The same applies if, for example, bolts 28A and 28C all break or if the fastening members 29 that fasten bolts 28A and 28C all come loose.

[0028] If, for example, bolt 28B breaks or the fastening member 29 that screws into bolt 28B comes loose, the fastening at mounting portion 26B cannot be maintained. In this case, mounting portion 26A is fixed to the structure 40, while mounting portion 26B is not. Here, bolt 28C of mounting portion 26B is screwed into the fastening member 29 via a spacer 30, and the spacer 30 is in contact with the structure 40 but not with the mounting portion 26B. As a result, mounting portion 26B lifts away from the structure 40 and gets caught on the spacer 30 of bolt 28C, which is recognized as an abnormality by visual inspection. The same applies if either bolt 28B or 28C breaks or if any of the fastening members 29 that fasten bolts 28B or 28C come loose.

[0029] If, for example, bolts 28A and 28B break, or if the fastening members 29 that screw into bolts 28A and 28B come loose, the fastening at mounting portions 26A and 26B cannot be maintained. In this case, bolt 28C of mounting portion 26B is screwed into the fastening member 29 via a spacer 30, and the spacer 30 is in contact with the structure 40 but not with mounting portion 26B. As a result, both mounting portions 26A and 26B fall off the structure 40, and bolt 28C becomes caught only on the spacer 30, which is recognized as an abnormality by visual inspection.

[0030] Even if, for example, bolt 28C breaks or the fastening member 29 that screws into bolt 28C comes loose, the fastening at the mounting parts 26A and 26B is maintained by bolts 28A and 28B and the fastening member 29, so the power supply unit 10 is fixed to the structure 40 by the mounting member 20.

[0031] Next, a lighting system comprising a power supply system 51 and a lighting device 70 will be described using Figure 4. Figure 4 is a block diagram showing the configuration of a lighting system 100, which is an example of an embodiment. As shown in Figure 4, for example, the lighting system 100 comprises a lighting device 70 and a power supply system 51 having a power supply unit 10 that supplies a DC voltage to the lighting device 70. The power supply system 51 has a power supply unit 10 and a mounting member 20 for the power supply unit 10, and is provided at a location away from the lighting device 70. The power supply system 51 is electrically connected to the lighting device 70 via the power lines 50 (see Figure 1) of the power supply unit 10. By not having the power supply system 51 built into the lighting device 70 but being provided outside the lighting device 70, the lighting device 70 can be made smaller, and in particular, its height can be greatly reduced.

[0032] The power supply unit 10 forms a power supply system 51 by fixing the extension portion 12 and the locking portion 23 of the mounting member 20 via the fixing portion 24. The power supply system 51 has the mounting member 20 and the power supply unit 10 and can be installed at a location away from the lighting device 70, for example, on the exterior wall of a high-rise building or on the railing of a bridge. When the power supply system 51 is used, it becomes possible to expand the installation locations of the lighting device 70 to various structures.

[0033] Furthermore, the above embodiments can be modified as appropriate without impairing the purpose of this disclosure. For example, in the above embodiments, a Type 1 nut with a chamfer on one side was used for the nut 29b, but a Type 3 nut that is chamfered on both sides and is thinner than a Type 1 nut may be used. In this case, the power supply unit 10 can be firmly fixed to the structure 40 even at sites where the construction space is limited.
