As shown in FIGS. 1 to 3, the universal bracket 1 (an example of a universal fixture) includes an installation part 10 attached to a wall surface that is a vertical installation surface, and an attachment part 20 connected below the installation part 10. And a fixing member 40 fixed to the mounting portion 20. The attachment part 20 is comprised from the horizontal rotation part 21 connected to the installation part 10, and the angle adjustment part 22 to which the fire detector (not shown) which comprises a sensor is attached so that angle adjustment is possible. The horizontal rotation part 21 constitutes a first attachment part, and the angle adjustment part 22 constitutes a second attachment part. The installation part 10, the attachment part 20, and the fixing member 40 are formed by processing a stainless steel (SUS) plate.

  The installation portion 10 is formed with a substantially square vertical plate 11 facing the wall surface. A connection plate 12 having a substantially rectangular shape is formed at the lower end of the vertical plate 11 perpendicular to the vertical plate 11. Furthermore, the 1st installation part side plate 13a and the 2nd installation part side plate 13b which contact any of the vertical board 11 and the connection board 12 are formed. The vertical plate 11 constitutes a counter plate that faces the installation surface.

  The vertical plate 11 is formed with two dharma holes 14a on both sides on the upper end side thereof, and is formed with two small dharma holes 14b smaller than the dharma holes 14a on the inner side of each dharma hole 14a. The vertical plate 11 is fixed to a wall surface by inserting a screw (not shown) into the dharma hole 14a and the small dharma hole 14b. Further, a vertical plate wiring hole 15 is formed in the vertical plate 11 for passing a lead wire connected to the fire detector.

  A substantially rectangular horizontal plate 23 is formed in the horizontal rotating portion 21 so as to face the connection plate 12. The horizontal plate 23 constitutes a fixing plate for fixing the fixing member 40. On both sides of the horizontal plate 23, a first horizontal rotating portion side plate 24a and a second horizontal rotating portion side plate 24b (see FIG. 4) are formed vertically downward with respect to the horizontal plate 23.

  The angle adjusting unit 22 includes a mounting plate 25 to which the fire detector is mounted, and a first angle adjusting unit side plate 26a and a second angle adjusting unit side plate 26b that are perpendicular to the mounting plate 25 on both sides of the mounting plate 25 (see FIG. 4) is formed. The first angle adjusting unit side plate 26 a and the second angle adjusting unit side plate 26 b are attached to the first horizontal rotating unit side plate 24 a and the second horizontal rotating unit side plate 24 b by the first bolt 27 and the second bolt 29. Thereby, the angle adjustment part 22 and the horizontal rotation part 21 are connected. The mounting plate 25 is formed with a mounting plate wiring hole 30 for passing a lead wire connected to the fire detector.

  As shown in FIG. 4, a hole 16 is formed in the connection plate 12. An annular fixing member 40 is disposed above the hole 16. The diameter of the fixing member 40, that is, the outer diameter is formed larger than the diameter of the hole portion 16. That is, the fixing member 40 has a larger outer shape than the hole portion 16. Further, the inner diameter of the fixing member 40 constitutes a fixing member hole 43.

  A horizontal plate hole 31 is formed at the center of the horizontal plate 23. An annular ring 42 is fitted in the horizontal plate hole 31. A lead wire connected to the fire detector is passed through the hole 16 and the ring 42.

  When attaching the attachment portion 20 to the installation portion 10, the horizontal plate 23 is connected to the connection plate 12, and the fixing member 40 is disposed on the connection plate 12. Then, the fixing member bolt 41 is inserted into the bolt hole of the fixing member 40 and further inserted into the bolt hole of the horizontal plate 23 to fasten the fixing member 40, the connection plate 12 and the horizontal plate 23. That is, the connection plate 12 is sandwiched between the fixing member 40 and the horizontal plate 23. Note that the fixing member bolt 41 constitutes a fastening member.

  More specifically, after the fixing member bolt 41 is inserted into the bolt hole of the fixing member 40, the fixing member bolt 41 is inserted into the bolt hole of the horizontal plate 23 via the hole portion 16 and fastened. Therefore, both the fixing member 40 and the horizontal rotation unit 21 can be rotated in the horizontal direction with respect to the installation unit 10 attached to the wall surface.

  The fixing member bolts 41 are arranged at equal intervals so as to be substantially inscribed in the inner peripheral surface of the round hole 16. Therefore, the fixing member bolt 41 is fixed to the installation portion 10 with the center of the hole 16 as an axis, without removing the fixing member bolt 41 from the fixing member 40 and the horizontal rotating portion 21 only by loosening the fastening by the fixing member bolt 41. Both 40 and the horizontal rotation part 21 can be rotated in the horizontal direction.

  When the angle adjusting unit 22 is attached to the horizontal rotating unit 21, the first bolt 27 is formed in the arc-shaped first arc groove 28a centered on the second bolt 29 formed on the first angle adjusting unit side plate 26a, and the second Bolts of the first horizontal rotating portion side plate 24a and the second horizontal rotating portion side plate 24b are respectively inserted into arc-shaped second arc grooves 28b formed in the second angle adjusting portion side plate 26b with the bolt 29 as the center. Fastened to each hole. Accordingly, by loosening the fastening by the first bolt 27 and the second bolt 29, the angle adjusting unit 22 can rotate in the vertical direction around the second bolt 29.

  Therefore, the horizontal rotation of the horizontal rotation unit 21 with respect to the installation unit 10 and the vertical rotation of the angle adjustment unit 22 with respect to the horizontal rotation unit 21 in the vertical direction around the second bolt 29 are performed on the mounting plate 25. The direction of the attached fire detector can be directed to an arbitrary direction, and the direction can be finely adjusted.

  Next, as shown in FIGS. 5 and 6, a description will be given using a cross-sectional view of the universal bracket 1. The plate thickness t1 of the SUS plate constituting the installation unit 10 is thicker (thickness is larger) than the plate thickness t2 of the SUS plate constituting the horizontal rotation unit 21. Furthermore, the plate thickness t2 is thicker (thickness is greater) than the plate thickness t3 of the SUS plate constituting the angle adjusting unit 22. That is, in the universal metal fitting 1, the plate thickness t1 of the installation portion 10 close to the wall surface is the thickest, and the plate thickness of the constituent material decreases in order of the plate thickness t2 of the horizontal rotation portion 21 and the plate thickness t3 of the angle adjustment portion 22 It is formed as follows. For this reason, even when vibration is transmitted from the wall surface, the free metal fitting 1 can be made difficult to resonate.

  As described above, the mounting bracket 10 includes the mounting portion 10, the mounting portion 20 connected to the mounting portion 10, and the fixing member 40 connected to the mounting portion 20, and the mounting portion 10 can be set on the mounting surface.

Since the fixing member 40 and the horizontal plate 23 can be rotated with the connection plate 12 sandwiched therebetween, the fire detector can be easily rotated in an arbitrary direction.

  Further, the connecting plate 12 has a hole 16, the fixing member 40 has an outer shape larger than the hole 16, and the fixing member 40 and the fixing plate 23 are fixed by a fixing member bolt 41 passing through the hole 16, Both the fixing member 40 and the horizontal rotating portion 21 having the fixing plate 23 can be rotated in the horizontal direction.

  The mounting portion 20 includes a horizontal rotating portion 21 having a horizontal plate 23 and an angle adjusting portion 22 having a mounting plate 25. The installation portion 10, the horizontal rotating portion 21, and the angle adjusting portion 22 are It is formed of a plate-like member, and since the thickness of the horizontal rotation part 21 is smaller than that of the installation part 10 and the thickness of the angle adjustment part 22 is smaller than that of the horizontal rotation part 21, even when vibration is transmitted from the wall surface, it is free The metal fitting 1 can be made difficult to resonate.

  In this embodiment, the installation unit 10 is attached to a wall surface that is a vertical installation surface. However, the installation unit 10 may be attached using a horizontal surface such as a ceiling as the installation surface. In this embodiment, the mounting plate 25 is provided with a fire sensor. However, other types of sensors such as a smoke sensor, a gas sensor, and a surveillance camera may be provided.

  In this embodiment, the fixing member 40 has a ring shape and a circular outer shape, but is larger than the hole portion 16 and interferes with the vertical plate 11, the first installation portion side plate 13a, and the second installation portion side plate 13b. As long as the shape is not, it may have an outer shape other than a circle such as a flower shape or a polygon.

  Moreover, in this embodiment, the lead wire connected to the fire detector includes the mounting plate wiring hole 30 of the angle adjustment unit 22, the horizontal plate hole 31 of the horizontal plate 23, the hole 16 of the connection plate 12, and the fixing member 40. The hole portion 16 has a round hole shape because the fixing member hole 43 and the vertical plate wiring hole 15 of the vertical plate 11 are sequentially inserted into the fixing plate hole 43 and drawn into the inner surface side of the wall surface. However, when it is not necessary to insert the lead wire, the hole portion 16 may have another hole shape such as a ring shape as long as the fixing member 40 can be rotated in the horizontal direction. The plate 23 and the fixing member 40 need not be provided with the horizontal plate hole 31 and the fixing member hole 43.

  In this embodiment, the universal bracket 1 is described as an example of the universal fixture. However, a universal fixture made of a material other than the bracket, for example, a resin, may be used.
