(Embodiment 1)
(1) Outline As shown in FIGS. 1 and 2, the disaster prevention device 1 according to the present embodiment is a transmitter 10 with an indicator lamp. The transmitter with indicator lamp 10 (disaster prevention device 1) includes a transmitter 2 and an indicator lamp 3. The “disaster prevention device” as used in the present disclosure is a device that is installed in a facility for the purpose of, for example, preventing disasters such as fire, preventing the spread of damage caused by disasters, or recovering from disasters.

  Such a disaster prevention device 1 (transmitter 10 with an indicator lamp) is used for a facility. Although this embodiment illustrates the case where the disaster prevention device 1 is used in a non-residential facility such as an office building, a school, a welfare facility, a commercial facility, a theme park, a hospital, a hotel, or a factory, for example, this is not the only example. Instead, the disaster prevention device 1 may be used in a facility such as an apartment house or a detached house. The disaster prevention device 1 is not limited to indoor use, and may be used in a specific space in an outdoor facility such as a park or a ground.

  The disaster prevention device 1 is installed in the facility in a state of being attached to the attachment target 4. As shown in FIG. 3, the attachment object 4 is a plate-like member (plate material) in which an attachment hole 41 penetrating in the front-rear direction is formed. In the present embodiment, as an example, the attachment object 4 is a frame-shaped attachment adapter.

  Here, as a structure for attaching the disaster prevention device 1 to the attachment object 4, the disaster prevention device 1 adopts the following configuration. That is, the disaster prevention device 1 includes a collar piece 11, an insertion portion 12, and a sandwich piece 13 as shown in FIGS. 1 and 2. The disaster prevention device 1 is attached to the attachment target 12 by sandwiching the periphery of the attachment hole 41 in the attachment object 4 between the flange piece 11 and the sandwiching piece 13 in a state where the insertion portion 12 is inserted into the attachment hole 41 of the attachment object 4. 4 is attached. In short, the disaster prevention device 1 according to the present embodiment is attached by sandwiching a part of the attachment target 4.

  According to this configuration, the disaster prevention device 1 can be installed by sandwiching the periphery of the mounting hole 41 in the mounting target 4 between the collar piece 11 and the sandwiching piece 13, so that the mounting target is independent of the thickness of the mounting target 4. The amount of protrusion of the disaster prevention device 1 from the front surface (front surface) of 4 can be made uniform. Therefore, in the disaster prevention equipment 1 according to the present embodiment, there is an advantage that variation in the amount of protrusion of the disaster prevention equipment 1 from the front surface of the attachment target 4 can be suppressed to be small.

  Moreover, the transmitter 2 of the disaster prevention device 1 according to the present embodiment employs the following configuration. That is, the transmitter 2 includes a case 21, a push button 22, and a circuit block 23 (see FIG. 6). As shown in FIGS. 4A to 4C, the case 21 has a circular front surface 211. The push button 22 has an operation surface 221 disposed on the front surface 211 of the case 21.

(2.2) Transmitter Next, the configuration of the transmitter 2 in the disaster prevention device 1 (transmitter with indicator lamp 10) according to the present embodiment will be described.

  As illustrated in FIG. 6, the transmitter 2 includes a case 21, a push button 22, and a circuit block 23.

  The case 21 has a circular front surface 211. The case 21 has a body 24 and a cover 25. The body 24 is fixed to the attachment object 4. The cover 25 is attached to the front surface of the body 24. However, in this embodiment, the body 24 is not directly fixed to the attachment target 4 but is indirectly fixed to the attachment target 4 by being fixed to the indicator lamp 3. Further, the cover 25 includes a front surface 211 of the case 21. That is, the front surface of the cover 25 constitutes the front surface 211 of the case 21.

  The push button 22 has an operation surface 221 disposed on the front surface 211 of the case 21. The push button 22 is operated when the operation surface 221 is relatively strongly pushed backward. The operation surface 221 of the push button 22 is disposed at the center of the front surface 211 of the case 21. In the present embodiment, the operation surface 221 of the push button 22 has a circular shape with a smaller diameter than the front surface 211 of the case 21. Furthermore, in this embodiment, as shown in FIG. 4A, the center point of the operation surface 221 of the push button 22 and the center point of the front surface 211 of the case 21 coincide. That is, the operation surface 221 of the push button 22 is concentric with the front surface 211 of the case 21.

The push button 22 is configured to be movable between a steady position and an operation position. In the state where the push button 22 is in the steady position, the operation surface 221 of the push button 22 is substantially flush with the front surface 211 of the case 21 as shown in FIG. When the operation surface 221 is pushed backward while the push button 22 is in the steady position, the push button 22 moves to the operation position. In the state where the push button 22 is in the operation position, the operation surface 221 of the push button 22 is recessed backward with respect to the front surface 211 of the case 21 as shown in FIG. 7A. The push button 22 is a self-holding type button, and once moved to the operation position, the push button 22 does not automatically return to the steady position but returns to the steady position when an operation piece 213 described later is operated.

  The circuit block 23 is configured by mounting various electronic components on a printed wiring board. The circuit block 23 includes, for example, a switch, an LED (Light Emitting Diode), a terminal component, and the like. The switch is linked to the push button 22, and if the push button 22 is in the steady position, the switch is turned off, and if the push button 22 is in the operation position, the switch is turned on. The LED is lit (emitted) while the switch is on. In the present embodiment, the push button 22 has translucency, and LED light is output forward through the push button 22. The terminal parts of the circuit block 23 are parts for mechanically and electrically connecting electric wires connected to a receiver or the like. In this embodiment, the terminal component of the circuit block 23 is a plug-in type terminal, and constitutes a so-called quick connection terminal in which the electric wire is connected by inserting the electric wire.

Moreover, the case 21 has a storage portion 28 that stores at least one of the operation piece 213 and the connection portion 214, as shown in FIG. 7B. The storage unit 28 has an opening surface 281 in a part of the front surface 211 of the case 21. The operation piece 213 is a button for releasing the operation state of the push button 22. As described above, when the operation piece 213 is operated, the push button 22 at the operation position returns (moves) to the steady position. ) That is, the operation state of the push button 22 (the state at the operation position) is released by the operation of the operation piece 213. The connection unit 214 is a connector for connecting a telephone (handset), and as an example, is a jack for inserting a mini plug of the telephone. The telephone is used to realize communication between the transmitter 2 and the receiver. In the present embodiment, both the operation piece 213 and the connection portion 214 are stored in the storage portion 28.

  In the present embodiment, an opening 251 having a circular shape in front view that penetrates the cover 25 in the front-rear direction is formed at the center of the front surface 211 of the case 21. The opening 251 is a hole for exposing the operation surface 221 of the push button 22 forward, and is formed concentrically on the front surface 211 of the case 21 like the operation surface 221 of the push button 22. The opening surface 281 of the storage unit 28 is disposed above the opening 251 in the front surface 211 of the case 21 and adjacent to the opening 251. Further, a recess 252 that is recessed rearward with respect to the front surface 211 of the case 21 is formed between the opening surface 281 of the storage portion 28 and the opening portion 251 of the case 21. Thereby, the storage part 28 and the opening part 251 are connected by the hollow 252.

  The transmitter 2 further includes a lid 29. The lid body 29 is configured to be movable between a closed position and an open position. The closed position is a position where the lid 29 covers the opening surface 281 of the storage portion 28 as shown in FIG. 7A. The open position is a position at which the lid 29 opens the opening surface 281 of the storage portion 28 as shown in FIG. 7B. In the present embodiment, the front surface of the lid body 29 and the front surface 211 of the case 21 are flat as shown in FIG. 7A with the lid body 29 in the closed position. That is, the lid body 29 is not shaped to protrude forward from the front surface 211 of the case 21, and the front surface 211 of the case 21 and the front surface of the lid body 29 are substantially flush.

  The lid 29 is held by the cover 25 in a rotatable state so as to be movable between a closed position and an open position. Specifically, the lid 29 has a fulcrum part 291 and a free end part 292 at both ends in the arrangement direction (vertical direction) in which the push button 22 and the opening surface 281 of the storage part 28 are arranged. The fulcrum part 291 is a part that becomes a rotation axis when the lid 29 is rotated (moved). That is, the lid body 29 is configured to be rotatable around the fulcrum portion 291 so that the free end portion 292 changes the distance from the front surface 211 of the case 21. Here, the upper end portion of the lid body 29 constitutes a fulcrum portion 291, and the lower end portion of the lid body 29 constitutes a free end portion 292. In other words, the lid body 29 performs a vertical opening operation with the upper end portion (fulcrum portion 291) of the lid body 29 as an axis.

  Here, as shown in FIG. 6, the free end 292 is abutted against the push button 22 in the vertical direction with the lid 29 in the closed position. That is, since the storage portion 28 and the opening portion 251 are connected by the depression 252, when the lid body 29 is in the closed position and the push button 22 is in the steady position, the lower end portion (free end portion) of the lid body 29. 292) is abutted against the outer peripheral surface (upper surface) of the push button 22. Therefore, in a state where the push button 22 is operated and moved to the operation position, a human finger can access the free end 292 of the lid 29 from the opening 251 through the recess 252. As a result, the lid 29 can be easily opened (moved to the open position) by pulling the free end 292 forward (forward) while the front surface of the lid 29 is flat.

  Hereinafter, a more detailed configuration of the transmitter 2 will be described.

  As shown in FIGS. 8 and 9, the body 24 includes a first body 241, a second body 242, and an inner cover 243. The first body 241 is formed in a disc shape. The second body 242 is formed in a rectangular parallelepiped shape and protrudes rearward from the central portion of the first body 241. Here, the second body 242 and the first body 241 are integrally formed, and the rectangular front surface of the second body 242 is open. The inner cover 243 is fixed to the first body 241 with screws 245 (see FIG. 9) so as to close the opening (front surface) of the second body 242.

  The push button 22 is held by the inner cover 243 so as to be movable between a steady position and an operation position. The circuit block 23 is accommodated in a space formed between the second body 242 and the inner cover 243. On the rear surface of the second body 242, a terminal hole for inserting an electric wire connected to the terminal component of the circuit block 23 is formed. The periphery of the terminal hole on the rear surface of the second body 242 is covered with a first waterproof cap 71 (see FIG. 2) for preventing water from entering the second body 242 from the terminal hole. The first waterproof cap 71 can be omitted as appropriate.

  The first body 241 is formed with a plurality of (here, two) assembly holes 244 that penetrate the first body 241 in the front-rear direction. The plurality of assembly holes 244 are holes through which a plurality of (here, two) assembly screws 215 for fixing the transmitter 2 to the indicator lamp 3 are passed, and are arranged at both ends in the vertical direction of the first body 241. ing. That is, in the transmitter 2, the body 24 is fixed to the indicator lamp 3 by fitting (screwing) the plurality of assembly screws 215 to the indicator lamp 3 through the plurality of assembly holes 244.

  The cover 25 has a flat plate portion 253 and a peripheral wall portion 254. The flat plate portion 253 is formed in a disc shape having an opening 251 at the center. The peripheral wall portion 254 protrudes rearward from the outer peripheral edge on the rear surface of the flat plate portion 253. The peripheral wall portion 254 is formed over the entire outer periphery of the rear surface of the flat plate portion 253. Thereby, in a state where the cover 25 is attached to the body 24, the front surface of the first body 241 is covered with the flat plate portion 253, and the outer peripheral surface of the first body 241 is covered with the peripheral wall portion 254.

  In a state where the cover 25 is attached to the body 24, the first body 241 and the cover 25 constitute a flange portion 212 (see FIG. 6). That is, the flange portion 212 formed of the outer peripheral portion of the case 21 is a portion protruding from the front end portion of the second body 242 in the case 21 in a direction (vertical direction and horizontal direction) orthogonal to the front-rear direction.

  The case 21 (the body 24 and the cover 25) is made of resin such as polycarbonate (PC) resin, ASA (Acrylonitrile Styrene Acrylate) resin, PC / ABS (Acrylonitrile Butadiene Styrene) alloy resin, or ABS resin. In the present embodiment, as an example, the first body 241 and the second body 242 are made of PC / ABS alloy resin, the inner cover 243 is made of ABS resin, and the cover 25 is made of ASA resin.

  Further, the case 21 further includes a first coupling structure 26 (coupling structure) for mechanically coupling the body 24 and the cover 25 as shown in FIG. 10A. The first coupling structure 26 mechanically couples the body 24 and the cover 25 by a snap fit method. That is, the first coupling structure 26 uses the elasticity of at least one of the body 24 and the cover 25 to fit one of the convex portions of the body 24 and the cover 25 into the other concave portion and hook the body 24 and the cover 25. And the cover 25 are mechanically coupled. The first coupling structure 26 is stored in the storage unit 28. Therefore, when the lid 29 is in the closed position, the first coupling structure 26 is covered with the lid 29 and cannot be seen from the front.

  The first coupling structure 26 has a pair of claw portions 261 and a pair of hook portions 262. The pair of claws 261 are arranged in one direction (here, the left-right direction) along the front surface 211 of the case 21. The pair of hook portions 262 is a structure for hooking the pair of claw portions 261. One of the body 24 and the cover 25 is provided with a pair of claw portions 261, and the other is provided with a pair of hook portions 262. In the present embodiment, a pair of claw portions 261 is provided on the cover 25, and a pair of hook portions 262 are provided on the body 24. That is, the first coupling structure 26 mechanically couples the body 24 and the cover 25 by the pair of claw portions 261 being hooked on the pair of hook portions 262.

  Specifically, as shown in FIG. 9, the pair of claw portions 261 protrudes rearward from the rear surface of the flat plate portion 253 of the cover 25 and the periphery of the opening surface 281 of the storage portion 28. A hook portion 261 a (see FIG. 11A) that protrudes toward each other is formed at the front end portions (rear end portions) of the pair of claw portions 261. As shown in FIG. 8, the pair of hooking portions 262 protrudes forward from the front surface of the inner cover 243 of the body 24 and corresponding to the bottom surface of the storage portion 28. A hook portion 262 a (see FIG. 11A) that protrudes away from each other is formed at the front end portions (front end portions) of the pair of hook portions 262. Thereby, in the state where the cover 25 is attached to the body 24, as shown in FIG. 11A, the hook portions 261a of the pair of claws 261 are hooked on the hook portions 262a of the pair of hook portions 262, and the first coupling structure 26 The body 24 and the cover 25 are coupled together. FIG. 11A is an enlarged view of a region X1 in FIG. 10A.

  Further, as shown in FIG. 10A, the case 21 further includes a second coupling structure 27 that mechanically couples the body 24 and the cover 25 by a snap fit method, in addition to the first coupling structure 26. The second coupling structure 27 is disposed on the opposite side of the first coupling structure 26 across the push button 22 in the vertical direction. In other words, the push button 22 is disposed between the first coupling structure 26 and the second coupling structure 27 in the vertical direction (first direction) along the front surface 211 of the case 21. In the present embodiment, the first coupling structure 26 is disposed above the push button 22, and the second coupling structure 27 is disposed below the push button 22.

The second coupling structure 27 has a pair of auxiliary claw portions 271 and a pair of auxiliary hooking portions 272. The pair of auxiliary claw portions 271 are aligned in the left-right direction (second direction) perpendicular to the up-down direction (first direction) along the front surface 211 of the case 21. The pair of auxiliary hooking portions 272 is a structure for hooking the pair of auxiliary claw portions 271. One of the body 24 and the cover 25 is provided with a pair of auxiliary claw portions 271, and the other is provided with a pair of auxiliary hooking portions 272.
In the present embodiment, a pair of auxiliary claw portions 271 are provided on the cover 25, and a pair of auxiliary hook portions 272 are provided on the body 24. That is, the second coupling structure 27 mechanically couples the body 24 and the cover 25 by the pair of auxiliary claw portions 271 being hooked on the pair of auxiliary hooking portions 272.

  Specifically, as shown in FIG. 9, the pair of auxiliary claw portions 271 protrudes rearward from the rear surface of the flat plate portion 253 of the cover 25. A hook portion 271a (see FIG. 11B) that protrudes away from each other is formed at the front end portion (rear end portion) of the pair of auxiliary claw portions 271. As shown in FIG. 8, the pair of auxiliary hooking portions 272 are the first body 241 of the body 24 and are provided in holes formed on both sides in the left-right direction of the lower assembly hole 244. The pair of auxiliary hooking portions 272 have hooking portions 272a (see FIG. 11B) that protrude from the inner peripheral surfaces of the pair of holes toward each other. Thus, in the state where the cover 25 is attached to the body 24, as shown in FIG. 11B, the hook portions 271a of the pair of auxiliary claw portions 271 are hooked on the hook portions 272a of the pair of auxiliary hook portions 272, and the second coupling is performed. The structure 24 joins the body 24 and the cover 25. FIG. 11B is a view of the region X2 in FIG. 10A as viewed from the rear.

  Here, each of the pair of auxiliary claw portions 271 is configured such that the amount of engagement with respect to each of the pair of auxiliary hooking portions 272 becomes smaller as the push button 22 is approached in the vertical direction (first direction). The “hang amount” in the present disclosure is a dimension of a portion of the hook portion 271a of the auxiliary claw portion 271 that is actually hooked on the hook portion 272a of the auxiliary hook portion 272. In the example of FIG. 11B, the dimension in the left-right direction of the portion of the hook portion 271a of the auxiliary claw portion 271 that overlaps with the hook portion 272a of the auxiliary hook portion 272 is the “hang amount”. That is, as shown in FIG. 11B, the amount of protrusion from the front end portion (rear end portion) of the pair of auxiliary claw portions 271 at the hook portion 271a of the auxiliary claw portion 271 is smaller toward the upper end portion near the push button 22. It has become. Even in such a shape, when the cover 25 is attached to the body 24, at least the lower end portions of the hook portions 271a of the pair of auxiliary claw portions 271 are hooked on the hook portions 272a of the pair of auxiliary hook portions 272.

  By the way, when removing the cover 25 from the body 24, the operator first releases the coupling between the body 24 and the cover 25 by the first coupling structure 26 and then couples the body 24 and the cover 25 by the second coupling structure 27. Is released.

  That is, when removing the cover 25 from the body 24, the operator first inserts a jig such as a minus driver from the front into a gap formed between each claw portion 261 and each hook portion 262. As a result, each claw portion 261 is elastically deformed in the direction of arrow A1 in FIG. 10A, and the hook portions 261a of the pair of claws 261 are disengaged from the hook portions 262a of the pair of hook portions 262. The connection between the body 24 and the cover 25 is released.

  When the coupling between the body 24 and the cover 25 by the first coupling structure 26 is released, the operator next pulls the upper end portion of the cover 25 forward (forward). As a result, the cover 25 rotates in the direction of the arrow A2 in FIG. 10B with the lower end portion as a fulcrum. In FIG. 10B, the cover 25 after rotation is indicated by an imaginary line (two-dot chain line). At this time, the pair of auxiliary claw portions 271 is released from being hooked with the pair of auxiliary hooking portions 272 from the upper end side where the amount of hooking on each of the pair of auxiliary hooking portions 272 is small. When the cover 25 is rotated by a predetermined amount, the hook portions 271a of the pair of auxiliary claw portions 271 are completely detached from the hook portions 272a of the pair of auxiliary hook portions 272, and the body 24 and the cover 25 are coupled by the second coupling structure 27. Is released. As a result, the coupling by both the first coupling structure 26 and the second coupling structure 27 is released, and the cover 25 is removed from the body 24.

  On the other hand, before the coupling between the body 24 and the cover 25 by the first coupling structure 26 is released, the cover 25 is not easily detached from the body 24 even if the cover 25 is pulled forward (forward). For example, even if the cover 25 is pulled straight forward (forward), the hook portion 271a is hooked on the hook portion 272a, so that the coupling between the body 24 and the cover 25 by the second coupling structure 27 is not released, and the cover 25 and the body 24 Is maintained.

(2.3) Indicator lamp Next, the structure of the indicator lamp 3 in the disaster prevention apparatus 1 (transmitter 10 with an indicator lamp) which concerns on this embodiment is demonstrated.

  The indicator lamp 3 includes a housing 33 and a light source block 34 as shown in FIG.

  The housing 33 is formed in a circular shape when viewed from the front. The housing 33 has an annular light emitting portion 31 on the outer periphery of the front surface. The housing 33 accommodates the light source block 34. Of the housing 33, at least a portion that functions as the light emitting unit 31 has translucency, and light from the light source block 34 is output forward through the light emitting unit 31. Thereby, the light emission part 31 will light-emit, and an annular light will be visible for the person who looked at the indicator lamp 3 from the front.

  The housing 33 has a recess 32 inside the light emitting unit 31. The recess 32 opens in a circular shape when viewed from the front. In a state where the indicator lamp 3 is combined with the transmitter 2, a flange portion 212 (see FIG. 6) that is an outer peripheral portion of the case 21 is accommodated in the concave portion 32. In the present embodiment, a through hole 321 that penetrates the housing 33 in the front-rear direction is formed at the center of the bottom surface of the recess 32. The through hole 321 is a hole through which a part (second body 242) of the case 21 of the transmitter 2 passes, and is formed in a rectangular shape. Thus, in a state where the indicator lamp 3 is combined with the transmitter 2, the flange portion 212 including the outer peripheral portion of the case 21 is accommodated in the concave portion 32, and the second body 242 passes from the rear surface of the housing 33 through the through hole 321. Project backwards.

  Here, the dimension D2 (see FIG. 10B) in the front-rear direction of the flange portion 212 is equal to or greater than the depth D1 (see FIG. 13) of the recess 32 (D2 ≧ D1). Therefore, in the state where the indicator lamp 3 is combined with the transmitter 2, the front surface 211 of the case 21 of the transmitter 2 is flush with the front surface of the housing 33 (the light emitting unit 31) or protrudes forward from the front surface of the housing 33. become. In this embodiment, since the dimension D2 of the flange portion 212 in the front-rear direction is substantially equal to the depth D1 of the recess 32, the front surface 211 of the case 21 of the transmitter 2 is substantially the same as the front surface (light emitting portion 31) of the housing 33. (See FIG. 1).

  A pair of recesses 322 that are recessed backward with respect to the bottom surface of the recess 32 are formed on both sides of the through hole 321 in the left-right direction on the bottom surface of the recess 32. A pair of screw holes 323 are formed on both sides of the through hole 321 in the vertical direction on the bottom surface of the recess 32. The pair of screw holes 323 are holes for fitting (screwing) a plurality of (here, two) assembly screws 215 that fix the transmitter 2 to the indicator lamp 3. That is, the transmitter 2 is fixed to the indicator lamp 3 by fitting the plurality of assembly screws 215 into the pair of screw holes 323 of the indicator lamp 3 through the plurality of assembly holes 244.

  The light source block 34 is accommodated in the housing 33. The light source block 34 includes, for example, a light emitting element that outputs light when energized, such as an LED, and a terminal component. In the present embodiment, the light source block 34 is formed in an annular shape along the outer peripheral edge of the front surface of the housing 33 so as to emit light over substantially the entire area of the light emitting unit 31. The light source block 34 outputs light toward the front, so that the light from the light source block 34 is output forward through the light emitting unit 31 of the housing 33 as described above. The terminal parts of the light source block 34 are parts for mechanically and electrically connecting electric wires connected to a receiver or the like. In the present embodiment, the terminal component of the light source block 34 is a plug-in type terminal, and constitutes a so-called quick connection terminal in which the electric wire is connected by inserting the electric wire.

  Hereinafter, a more detailed configuration of the indicator lamp 3 will be described.

  The housing 33 has a first housing 35 and a second housing 36. The first housing 35 is formed in an annular shape. The second housing 36 is formed in a disc shape. The first housing 35 is attached to the front surface of the second housing 36. The first housing 35 is fixed to the second housing 36 with screws 331. The light emitting unit 31 is formed in the first housing 35, and the through hole 321 is formed in the second housing 36. The outer diameter of the first housing 35 is set larger than the outer diameter of the second housing 36.

  The light source block 34 is accommodated in a space formed between the first housing 35 and the second housing 36. The front surface of the light source block 34 is covered with a first housing 35. Therefore, in this embodiment, the 1st housing 35 has translucency. On the rear surface of the second housing 36 and below the through hole 321, a terminal hole for inserting an electric wire connected to the terminal component of the light source block 34 is formed. The periphery of the terminal hole on the rear surface of the second housing 36 is covered with a second waterproof cap 72 (see FIG. 2) for preventing water from entering the second housing 36 from the terminal hole. The second waterproof cap 72 can be omitted as appropriate.

  The housing 33 (the first housing 35 and the second housing 36) is made of resin such as PC resin, ASA resin, PC / ABS alloy resin, or ABS resin, for example.

  By the way, in this embodiment, since it is the indicator lamp 3 that is directly attached with respect to the attachment object 4, the structure for attaching the disaster prevention apparatus 1 (transmitter 10 with an indicator light) to the attachment object 4 is an indicator light. 3 is provided.

  That is, as shown in FIG. 13, the indicator lamp 3 includes a collar piece 11, an insertion portion 12, and a clip piece 13. The flange 11 is positioned in front of the periphery of the mounting hole 41 in the mounting target 4 having the mounting hole 41 penetrating in the front-rear direction. The insertion portion 12 is inserted into the attachment hole 41. The pinching piece 13 is located behind the mounting hole 41 in the mounting target 4 and sandwiches the mounting target 4 with the flange piece 11. The indicator lamp 3 configured as described above is attached to the attachment target 4 in a state where the attachment target 4 is sandwiched between the collar piece 11 and the sandwiching piece 13.

  As described above, the indicator lamp 3 is a part of the mounting target 4 (around the mounting hole 41) between the flange piece 11 and the sandwiching piece 13 in a state where the insertion portion 12 is inserted into the mounting hole 41 of the mounting target 4. Is attached to the attachment object 4. However, FIG. 13 represents not a permanently fixed state but a temporarily held state. The “main fixing” in the present disclosure means a state in which the indicator lamp 3 is completely fixed so as not to move relative to the attachment target 4. “Temporary holding” in the present disclosure means a state in which the indicator lamp 3 is held by the attachment target 4 but is relatively movable with respect to the attachment target 4.

  In short, in the state shown in FIG. 13, the clip piece 13 is only lightly touching the attachment object 4, and the indicator lamp 3 is in a state of moving relative to the attachment object 4 in the front-rear direction. As will be described in detail later, in the present embodiment, the clip piece 13 is also used as a temporary holding piece 14 for temporarily holding the indicator lamp 3 on the attachment target 4, and the clip piece 13 and the temporary holding piece 14 are integrated. It is configured. That is, in the state shown in FIG. 13, the sandwiching piece 13 functions as the temporary holding piece 14 by lightly touching the periphery of the mounting hole 41 in the mounting target 4 from behind.

  Below, the specific structure for attaching the disaster prevention apparatus 1 (transmitter 10 with an indicator lamp) which concerns on this embodiment to the attachment object 4 is demonstrated.

  The collar piece 11 is a portion projecting in a direction (vertical direction and horizontal direction) orthogonal to the front-rear direction in the front end portion of the housing 33. The flange 11 is formed over the entire outer peripheral edge of the front surface of the housing 33. In other words, the collar piece 11 is a portion protruding outward from the outer peripheral surface of the front end portion of the insertion portion 12. Therefore, at least a portion of the first housing 35 that protrudes outward from the outer peripheral edge of the front surface of the second housing 36 functions as the flange 11. Further, the insertion portion 12 is a portion protruding rearward from the rear surface of the collar piece 11. In the present embodiment, the disc-shaped second housing 36 constitutes the insertion portion 12.

  The outer diameter of the flange 11 is set to be larger than the inner diameter of the mounting hole 41 and smaller than the outer diameter of the countersink portion 43. The outer diameter of the insertion portion 12 is set smaller than the inner diameter of the mounting hole 41. Therefore, when the insertion portion 12 is inserted into the attachment hole 41 of the attachment target 4 from the front, the collar piece 11 comes into contact with the periphery of the attachment hole 41 on the front surface of the attachment target 4 so that the indicator lamp 3 moves backward. Is regulated. However, since the second packing 62 is disposed between the front surface of the attachment target 4 and the rear surface of the flange 11 of the disaster prevention device 1, the flange 11 does not directly contact the front surface of the attachment target 4. Indirect contact with the front surface of the mounting object 4 through the second packing 62. At this time, the collar piece 11 is accommodated in the countersink part 43 in the attachment object 4 in front view.

  Here, the indicator lamp 3 includes a plurality of sandwich pieces 13. The plurality of sandwiching pieces 13 are arranged so as to be arranged at intervals in the circumferential direction of the mounting hole 41. In the present embodiment, a plurality (two in this case) of sandwiching pieces 13 are arranged at the left end and the right end in the central portion of the housing 33 in the vertical direction. That is, the plurality (two in this case) of the sandwiching pieces 13 are arranged so as to be arranged at an interval of about 180 degrees in the circumferential direction of the mounting hole 41. Thereby, the indicator lamp 3 is attached to the attachment target 4 by sandwiching the attachment target 4 between the flange piece 11 and the plurality of sandwiching pieces 13 at a plurality of locations (left end portion and right end portion) of the housing 33.

  As shown in FIG. 14A, the indicator lamp 3 further includes a temporary holding piece 14 and an elastic portion 15. The temporary holding piece 14 has a variable amount of protrusion from the outer peripheral edge of the insertion portion 12 in a plane orthogonal to the front-rear direction. The elastic portion 15 causes the temporary holding piece 14 to exert an elastic force in a direction that increases the protruding amount of the temporary holding piece 14. The temporary holding piece 14 is located behind the periphery of the attachment hole 41 in the attachment object 4. In the present embodiment, as described above, the temporary holding piece 14 is also used as the sandwiching piece 13. That is, in a state where the temporary holding piece 14 (the sandwich piece 13) is mounted on the insertion portion 12, the temporary holding piece 14 is outward (left or right) from the outer peripheral surface 122 of the insertion portion 12, as shown in FIG. 14B. The elastic part 15 (refer FIG. 14A) receives the elastic force of the direction which enlarges the protrusion amount to the direction.

  The indicator lamp 3 further includes a restriction mechanism 16. The restriction mechanism 16 restricts the movement of the temporary holding piece 14 in the direction in which the distance between the temporary holding piece 14 and the flange piece 11 is increased. The restricting mechanism 16 restricts the movement of the temporary holding piece 14 so that the temporary holding piece 14 functions as the sandwiching piece 13. In short, in the direction in which the distance between the temporary holding piece 14 and the collar piece 11 is increased, that is, in the state where the movement of the temporary holding piece 14 to the rear is not restricted, the indicator lamp 3 is at least in the front-rear direction with respect to the attachment target 4. A temporary holding state is obtained. On the other hand, in a state where the movement of the temporary holding piece 14 to the rear is restricted by the restriction mechanism 16, the indicator lamp 3 is sandwiched between the attachment piece 4 between the pinching piece 13 (temporary holding piece 14) and the flange piece 11. Is in a permanently fixed state so as not to move relative to the attachment object 4. Therefore, the temporary holding piece 14 functions as the sandwiching piece 13 in a state where the backward movement of the temporary holding piece 14 is restricted by the restriction mechanism 16.

  More specifically, the sandwiching piece 13 (temporary holding piece 14) has a horizontal piece 17 and a vertical piece 18 as shown in FIGS. 14A and 14B. In the present embodiment, as an example, the sandwiching piece 13 (temporary holding piece 14) is an L-shaped metal fitting made of a single metal plate and formed in a substantially L shape with the horizontal piece 17 and the vertical piece 18. Here, the angle between the horizontal piece 17 and the vertical piece 18 is preferably set to be larger by several degrees to ten degrees (for example, 5 degrees) than the right angle (see FIG. 13). That is, the horizontal piece 17 and the vertical piece 18 do not cross each other strictly, but intersect at a slightly larger angle than a right angle. Thereby, in the state of this fixed, the pinching piece 13 can pinch | attach the mounting target 4 comparatively firmly between the hook pieces 11, and sufficient attachment strength of the indicator lamp 3 with respect to the mounting target 4 is ensured.

  The horizontal piece 17 has a first end 171 and a second end 172 at both ends in the longitudinal direction (left-right direction). The horizontal piece 17 has a rear surface of the insertion portion 12 such that the first end 171 is positioned on the outer peripheral edge side of the rear surface 121 of the insertion portion 12 and the second end 172 is positioned on the center side of the rear surface 121 of the insertion portion 12. 121. The vertical piece 18 protrudes forward from the first end 171 of the horizontal piece 17. Here, the vertical piece 18 is disposed along the outer peripheral surface 122 of the insertion portion 12.

  The sandwiching piece 13 configured as described above rotates by moving the first end 171 in the front-rear direction while the second end 172 of the horizontal piece 17 is held by the insertion part 12. Thereby, the amount of protrusion of the vertical piece 18 from the outer peripheral edge of the insertion portion 12 in the plane orthogonal to the front-rear direction changes and the clip piece 13 functions as the temporary holding piece 14. Specifically, the second end 172 of the horizontal piece 17 is held by the insertion portion 12 by being inserted into a later-described insertion recess 125 (see FIG. 14A) formed in the insertion portion 12. Therefore, the clip piece 13 rotates about the second end portion 172 as a fulcrum by moving the first end portion 171 in the front-rear direction. However, the fulcrum when the pinch piece 13 rotates is not limited to the second end portion 172. For example, the pinch piece 13 may rotate using the central portion in the longitudinal direction of the horizontal piece 17 as a fulcrum.

  The restricting mechanism 16 has a first screw portion 161 and a second screw portion 162. The first screw portion 161 is provided between the first end 171 and the second end 172 in the horizontal piece 17. The second screw portion 162 is fitted (screwed) to the first screw portion 161 to move the horizontal piece 17 in a direction approaching the rear surface 121 of the insertion portion 12. The second screw part 162 has an operation part 163 exposed in front of the insertion part 12. In the present embodiment, as an example, the first screw portion 161 is made of a female screw component (nut) having a screw hole, and the second screw portion 162 is made of a male screw component (bolt). In this case, the operation unit 163 includes a head of a male screw part.

  That is, as shown in FIGS. 14A and 14B, the second screw portion 162 is inserted from the front of the insertion portion 12 into the insertion portion 12 in a state where the sandwiching piece 13 (temporary holding piece 14) is disposed behind the insertion portion 12. And is fitted into (threaded into) the first screw portion 161. From this state, the second screw portion 162 is tightened by the operation of the operation portion 163 exposed in front of the insertion portion 12, so that the lateral piece 17 of the clip piece 13 (temporary holding piece 14) It moves in a direction approaching the rear surface 121. Thereby, the restriction mechanism 16 restricts the backward movement of the temporary holding piece 14 and causes the temporary holding piece 14 to function as the sandwiching piece 13. In other words, the front end portion of the vertical piece 18 is pressed from the rear around the mounting hole 41 in the mounting target 4, so that the mounting target 4 is sandwiched between the vertical piece 18 and the flange 11, and the indicator lamp 3 Is fixed.

  Here, a groove 123 having a shape corresponding to the sandwiching piece 13 is formed from the rear surface 121 to the outer peripheral surface 122 of the insertion portion 12 at a portion corresponding to the sandwiching piece 13 in the insertion portion 12. The sandwiching piece 13 is attached to the insertion portion 12 in a state where at least a part thereof is housed in the groove 123. An insertion hole 124 that penetrates the housing 33 in the front-rear direction is formed at the bottom surface of the groove 123 formed in the rear surface 121 of the insertion portion 12 and at a position corresponding to the first screw portion 161. The second screw portion 162 is fitted into the first screw portion 161 through the insertion hole 124. An insertion recess 125 is formed on the inner surface of the groove 123 formed on the rear surface 121 of the insertion portion 12 and on the inner surface located on the center side of the rear surface 121. When the second end 172 of the horizontal piece 17 is inserted into the insertion recess 125, the movement of the second end 172 in the front-rear direction is restricted, and the second end 172 of the horizontal piece 17 is inserted as described above. Held in the section 12.

  The elastic portion 15 is disposed between the first screw portion 161 and the second end portion 172 in the longitudinal direction (left-right direction) of the horizontal piece 17. Further, the elastic portion 15 is provided on the rear surface 121 of the insertion portion 12. The elastic part 15 is configured to apply an elastic force to the horizontal piece 17 in a direction to push the horizontal piece 17 backward.

  In the present embodiment, as an example, the elastic portion 15 is a cantilever-shaped resin spring made of a part of the insertion portion 12, as shown in FIG. 14A. The elastic part 15 protrudes toward the outer peripheral edge side of the rear surface 121 of the insertion part 12 from the center side end of the rear surface 121 of the insertion part 12 at the bottom surface of the groove 123 formed on the rear surface 121 of the insertion part 12. Cantilever. The elastic portion 15 includes a dowel 151 and a rib 152 that protrude rearward from the rear surface of the elastic portion 15. The dowel 151 is disposed at the center of the rear surface of the elastic portion 15. The dowel 151 is inserted into the fitting hole 173 formed in the horizontal piece 17, thereby defining the relative position of the sandwiching piece 13 with respect to the elastic part 15 in the plane along the rear surface 121 of the insertion part 12. The rib 152 is disposed at the end on the free end (tip) side of the rear surface of the elastic portion 15. The rib 152 is in contact with a portion between the first screw portion 161 and the second end portion 172 on the front surface of the horizontal piece 17, more specifically, a portion between the first screw portion 161 and the fitting hole 173. In other words, the elastic portion 15 applies an elastic force to the horizontal piece 17 so as to push the horizontal piece 17 backward from the front end surface (rear end surface) of the rib 152.

  As a result, the temporary holding piece 14 receives an elastic force in a direction to move the first end portion 171 backward at the horizontal piece 17, and the vertical piece 18 is separated from the outer peripheral surface 122 of the insertion portion 12. That is, it is urged so that the protruding amount of the vertical piece 18 from the outer peripheral edge of the insertion portion 12 is increased.

(3) Attachment method Next, the attachment method to the attachment object 4 of the transmitter 10 with an indicator light (disaster prevention apparatus 1) which concerns on this embodiment is demonstrated.

  As explained in the section of “(2.1) Overall configuration”, as an outline of the procedure for attaching the disaster prevention device 1 to the attachment target 4, for the plate-like attachment target 4 in which the attachment holes 41 are formed, First, the indicator lamp 3 is attached. In the present embodiment, the disaster prevention device 1 is indirectly attached to the housing 51 (see FIG. 3) via the attachment adapter that is the attachment object 4, so that the attachment object 4 is the front wall 511 ( (See FIG. 3).

  First, the operator combines the indicator lamp 3 from the front with respect to the attachment target 4 fixed to the casing 51 so that the insertion portion 12 of the indicator lamp 3 is inserted into the attachment hole 41 of the attachment target 4. Here, as shown in FIG. 15, the worker moves the indicator lamp 3 backward to a position where the flange 11 is pressed around the mounting hole 41 on the front surface of the mounting target 4. At this time, as shown in FIG. 13, the temporary holding piece 14 is around the mounting hole 41 in the mounting target 4 in a state where the protruding amount from the outer peripheral edge of the insertion portion 12 of the vertical piece 18 of the temporary holding piece 14 remains large. The temporary holding piece 14 cannot pass through the mounting hole 41. Therefore, the temporary holding piece 14 resists the elastic force of the elastic portion 15 and elastically deforms the temporary holding piece 14 itself so as to reduce the protruding amount of the vertical piece 18 from the outer peripheral edge of the insertion portion 12. The vertical piece 18 is displaced. In the state where the collar piece 11 is pressed around the mounting hole 41 on the front surface of the mounting target 4, the vertical piece 18 of the temporary holding piece 14 has the elastic force of the elastic portion 15 and the elastic force of the temporary holding piece 14 itself. Accordingly, the protrusion 12 is displaced so as to increase the amount of protrusion from the outer peripheral edge of the insertion portion 12.

  In other words, in the state shown in FIG. 13, the diameter of the imaginary circle passing through the outer end portion (the front end portion of the vertical piece 18) of the plurality (two in this case) of the temporary holding pieces 14 in the front view is Since it is larger than the inner diameter, the temporary holding piece 14 cannot pass through the mounting hole 41. From this state, the temporary holding piece 14 passes through the mounting hole 41 while the operator inserts the insertion portion 12 of the indicator lamp 3 into the mounting hole 41 of the mounting target 4 to reduce the diameter of the virtual circle. When the temporary holding piece 14 passes through the attachment hole 41, the diameter of the virtual circle returns to a state larger than the inner diameter of the attachment hole 41, so that the indicator lamp 3 displays the attachment object 4 as the flange 11 and the temporary holding piece 14 ( By being sandwiched between the vertical pieces 18), it is temporarily held with respect to the attachment object 4.

  Next, as shown in FIG. 15, the operator uses the jig Z <b> 1 such as a Phillips screwdriver to rotate the second screw portion 162 in the direction of the arrow A <b> 1 in FIG. The second screw portion 162 is tightened with respect to the one screw portion 161. Here, since the operation part 163 of the second screw part 162 is exposed in front of the insertion part 12, the operator can tighten the second screw part 162 from the front of the insertion part 12. In FIG. 15, of the two clip pieces 13 (temporary holding piece 14), the right clip piece 13 (temporary holding piece 14) is in a state where the tightening of the second screw portion 162 is completed, and the left clip piece 13. About (temporary holding piece 14), the state before the 2nd screw part 162 is tightened is shown.

  When the second screw portion 162 is tightened, the horizontal piece 17 of the temporary holding piece 14 moves in a direction approaching the rear surface 121 of the insertion portion 12, and the front end portion of the vertical piece 18 moves around the attachment hole 41 in the attachment object 4. It is pushed from the back. That is, the restriction mechanism 16 having the first screw portion 161 and the second screw portion 162 restricts the backward movement of the temporary holding piece 14 and causes the temporary holding piece 14 to function as the sandwiching piece 13. As a result, the indicator lamp 3 is sandwiched between the flange 11 and the sandwiching piece 13 (vertical piece 18) around the bottom of the counterbore 43 that is recessed around the attachment hole 41 in the attachment target 4 and It is permanently fixed to the attachment object 4.

  Next, the operator combines the transmitter 2 from the front with respect to the permanently fixed indicator lamp 3. At this time, the operator first inserts the second body 242 (see FIG. 8) of the transmitter 2 into the through-hole 321 (see FIG. 8) of the indicator lamp 3 so that the indicator light 3 fixed to the attachment object 4 is fixed. On the other hand, the body 24 (see FIG. 8) of the transmitter 2 is combined from the front. Then, the operator fixes the body 24 to the indicator lamp 3 with a plurality of assembly screws 215 (see FIG. 8). Thereafter, the operator completes the attachment of the transmitter 2 by fitting the cover 25 (see FIG. 8) to the body 24 from the front.

  By attaching the transmitter with indicator light 10 (disaster prevention device 1) to the attachment object 4 in this way, parts such as screws are not exposed forward, and the transmitter with indicator light 10 (disaster prevention device 1) looks good. Can be installed. Moreover, in this embodiment, since the dimension D2 (refer FIG. 10B) of the front-back direction of the flange part 212 of the transmitter 2 is substantially equal to the depth D1 (refer FIG. 13) of the recessed part 32 of the indicator lamp 3, it is transmitter 2. The front surface 211 of the case 21 is substantially flush with the front surface (light emitting portion 31) of the indicator lamp 3 (see FIG. 1).

  Furthermore, in this embodiment, the flange 11 of the disaster prevention device 1 is housed in the countersink portion 43 of the attachment target 4 in a front view. Therefore, compared with the flat attachment object, the disaster prevention device 1 can be attached to the attachment object 4 in the form in which the flange 11 is embedded further rearward, and the disaster prevention device 1 from the front surface of the front wall 511 of the housing 51 can be attached. The amount of protrusion can be kept small. In particular, if the amount of depression from the front surface of the front wall 511 of the housing 51 to the front surface of the countersink portion 43 in the attachment target 4 is substantially equal to the thickness of the flange 11, the front surface 211 of the case 21 of the transmitter 2 and the display The front surface of the lamp 3 is substantially flush with the front surface of the front wall 511 of the housing 51 (see FIG. 1). When there is the second packing 62 between the front surface of the attachment target 4 and the rear surface of the flange 11 of the disaster prevention device 1, the amount of depression from the front surface of the front wall 511 of the housing 51 to the front surface of the second packing 62 The thickness of the flange 11 may be set substantially equal.

  Here, when removing the indicator lamp 3 temporarily held or permanently fixed to the attachment object 4 from the attachment object 4, the operator completely removes the second screw part 162 from the first screw part 161, In a state where 13 is separated from the insertion portion 12, the insertion portion 12 may be pulled forward from the mounting hole 41.
