Description

The present invention relates to disaster prevention devices such as disaster prevention equipment storage boxes and fire hydrant devices that are equipped with position indicator lights and sound holes, or further equipped with transmitters, and that can be operated in the event of a fire or other emergency to notify of the occurrence of an abnormality.

Conventionally, disaster prevention equipment storage boxes are equipped with a transmitter and an indicator light (in this case, a position indicator light), and also have sound holes that correspond to the built-in bell or buzzer.

The location indicator light is a red indicator light that stays lit at all times to indicate the location of the disaster prevention equipment storage box and allow people in the vicinity to recognize the location of the transmitter in the event of an emergency. The transmitter turns on the push button switch by pressing in the protective plate located on the transmitter cover, which sends a fire notification signal to the receiver to sound an alarm. When the receiver receives a fire notification signal from the transmitter and outputs a fire alarm, it sends a district acoustic signal to the disaster prevention equipment storage box that sent the fire notification signal, which causes the bell or buzzer on the disaster prevention equipment storage box to sound and output a fire alarm sound.

Conventional disaster prevention equipment storage boxes are equipped with a transmitter, a position indicator light, and an audio hole, but in order to reduce the installation space required for these and make the disaster prevention equipment storage box smaller, a proposal has been made to integrate the position indicator light and the transmitter. The position indicator light and the transmitter are integrated by arranging the position indicator light using a flat light-emitting member with multiple LEDs distributed around the transmitter to emit light from a surface.

Fire hydrant devices are also known as disaster prevention devices equipped with transmitters, position indicator lights, and sound holes.

Japanese Patent Application Publication No. 9-102085 Design Registration No. 1005289 JP 2018-022540 A Design Registration No. 1493279 Design Registration No. 1493280 JP 2016-059647 A JP 2011-165114 A Japanese Utility Model Publication No. 42-014357 International Publication No. 2018/198642

However, in such disaster prevention devices that integrate a transmitter and a position indicator light, the transmitter functions as the operation unit, and the position indicator light and the sound hole function as the alarm unit, but the operation unit and the alarm unit are not separate, which can confuse the operator.

In addition, integrating a position indicator light with a transmitter requires the position indicator light to be structurally arranged so as to surround the transmitter, which restricts the shape of the position indicator light to a circular shape, resulting in a problem of low freedom in improving the design of the position indicator light.

The present invention aims to provide a disaster prevention device that can be made smaller by consolidating the equipment contained therein to reduce installation space, while improving operability and design.

(First invention: Consolidated arrangement of indicator lights and sound holes of disaster prevention device)

(Display surface of indicator light with acoustic hole)
Furthermore, a sound hole is provided on the front surface of the indicator frame of the indicator light.

(Overlapping arrangement of the indicator light area and the sound hole area)
In the first, second and fifth inventions, the display surface of the indicator light and the sound hole area are arranged so as to overlap each other at least partially.

(Sixth invention: An indicator light with a display surface, a transmitter, and an audio hole are centrally arranged on the front and side of the disaster prevention device)
Another aspect of the present invention is a disaster prevention device, comprising:

(Separate structure of push button switch and transmitter body)
The transmitters of the second and sixth inventions are separated into a transmitter body, a push button switch with a protective plate, and a maintenance door.
The push button switch and the maintenance door are provided on the front surface of the storage case, and the transmitter main body is provided inside the storage case.

(Relationship between indicator light and storage case)
The display surface of the indicator light shall be flush with the front surface of the housing case or the front surface and side surfaces of the housing case.

(Relationship between transmitter and storage case)
The top exposed height of the exposed parts of the transmitter (e.g. maintenance door, push button) shall be less than or equal to the exposed height of the display surface in front of the display surface.

(Seventh invention: Overlap of sound hole area, transmitter arrangement area and indicator light)
Another aspect of the present invention is a disaster prevention device, comprising:
The acoustic hole area, the transmitter arrangement area and the indicator light are arranged so that their arrangement positions at least partially overlap in the up-down or left-right direction (vertical or horizontal direction) when installed.

For example, the indicator light has a display surface on at least one of the left and right side surfaces of the storage case when in the installed state. Also, the indicator light has a sound hole on at least one of the left and right side surfaces and/or the top and bottom surfaces of the storage case when in the installed state.

(First invention: Effect of centralized arrangement of indicator lights and sound holes of disaster prevention device)
The present invention is a disaster prevention device characterized in that the indicator light and the acoustic hole area are arranged in one place, for example, an opening and/or a notch is provided in the indicator light, and an acoustic hole is provided in at least one of the openings and/or the notch, so that the arrangement of the indicator light functioning as the notification unit and the acoustic hole area can be consolidated to reduce the installation space and make the disaster prevention device smaller, while reliably avoiding the confusion of the operator that occurs when the transmitter functioning as the operation unit and the indicator light functioning as the notification unit are integrated as in the conventional case. In addition, even if the arrangement of the acoustic hole area and the indicator light is consolidated, the arrangement and shape of the indicator light are not restricted by the arrangement of the acoustic hole area, and the degree of freedom in the arrangement and shape of the indicator light is high, and the design can be improved.

(Second Invention: Effect of Concentrated Arrangement of Indicator Lights, Sound Holes, and Transmitters of Disaster Prevention Devices)
Another form of the present invention is a disaster prevention device characterized in that a transmitter, indicator light, and acoustic hole area are all concentrated in one location.For example, the indicator light is arranged to surround the transmitter, and an acoustic hole area is provided in at least one of the gap between the transmitter and the indicator light, the opening of the indicator light, and the cut-out portion of the indicator light.Therefore, the indicator light, acoustic hole, and transmitter can be concentrated in position, further reducing the installation space and making the disaster prevention device even smaller.

(Effect of flat indicator structure)
In addition, the indicator light has a substantially flat display frame that conforms to the exposed surface of the disaster prevention device, the display frame is a diffuse translucent material, and a light source that illuminates the diffuse translucent material is provided behind the display frame.Since the display portion of the indicator light is a substantially flat display frame that conforms to the exposed surface of the disaster prevention device, various display patterns that improve visibility from the front and sides can be easily formed.

(Effect of the display frame shape)
In addition, the display frame of the indicator light is formed in a frame-like, lattice-like, ring-like or divided ring-like shape, allowing for a variety of shapes while ensuring visibility from the front and sides, thereby enhancing design.

(Effect of integrating the indicator light and sound hole)
Furthermore, since the indicator light is provided with an acoustic hole, it is not necessary to process and form an acoustic hole in the cover plate of the disaster prevention device, and the structure can be simplified accordingly.

(Third Invention: Effect of Acoustic Path Functioning as Acoustic Hole)
Another form of the present invention is a disaster prevention device in which an acoustic path that functions as an acoustic hole is provided behind the indicator light and/or the indicator light, so that sound can be output and diffused efficiently by forming the acoustic path. Furthermore, if the acoustic path is provided only behind the indicator light, the acoustic path is hidden by the indicator light and cannot be seen from the front, which provides a new design and improves the design.

(Fourth Invention: Effect of Acoustic Horn)
Another form of the present invention is a disaster prevention device that notifies specified information by display and sound, in which an acoustic horn is formed in the indicator light and the specified information is output by sound via the acoustic horn, so that the sound from the acoustic device can be efficiently output and diffused to the outside, and the formation of the acoustic horn can greatly improve the design.

(Effect of the fifth aspect of the invention)
Another form of the present invention is a disaster prevention device in which an indicator light and an acoustic hole area are concentrated in one location in a storage case, and the indicator light has a display surface on the front and side of the storage case, thereby making it possible to miniaturize the disaster prevention device while reliably avoiding the confusion that occurs to the operator when, as in the past, a transmitter that functions as an operating unit and an indicator light that functions as an alarm unit are integrated together, and when the disaster prevention device is installed on a wall surface or the like, visibility from the front is maintained while visibility from the side is improved, and the design can also be improved.

(Effect of the arrangement of the indicator light and the sound hole area)
In addition, since the display surface of the indicator light is provided in a position that surrounds part or all of the periphery of the acoustic hole area or that sandwiches it from above, below, and/or below, left and right, a variety of shapes and arrangements of the display surface can be made, and when the disaster prevention device is installed on a wall or the like, visibility of the indicator light from the front and sides is ensured, there is a high degree of freedom in the arrangement and shape of the display surface, and design can be improved.

(Effect of the display surface of the indicator light provided with an acoustic hole area)
Furthermore, since an acoustic hole area is provided on the front surface of the display frame of the indicator light, the shape and arrangement of the display frame are no longer restricted by the acoustic hole area, and the degree of freedom regarding the shape and arrangement of the display frame can be increased.

(Effect of overlapping the indicator light area and the sound hole area)
In addition, in the first, second and fifth inventions, the display surface of the indicator light and the acoustic hole area are arranged so that they overlap at least partially with each other, thereby alleviating constraints such as space for arranging the indicator light and acoustic hole on the front of the device, and improving design freedom.

(Effect of the Sixth Invention)
Another form of the present invention is a disaster prevention device in which a transmitter, indicator light, and sound hole area are concentrated in one location on the front of the storage case, and the indicator light has display surfaces on the front and side of the storage case, thereby making it possible to further miniaturize the disaster prevention device, and when the disaster prevention device is installed on a wall surface or the like, visibility from the front is ensured while visibility from the side is improved, and the design can also be improved.

(Effect of the arrangement of indicator lights and transmitters with sound holes)
In addition, the display surface of the indicator light is located at a position that surrounds the transmitter, a position that surrounds part or all of the transmitter, or a position that sandwiches the transmitter from above, below, and/or below, and/or from the left and right, and an acoustic hole is provided on at least the front display surface of the indicator light, so that the display frame is not restricted by the position of the acoustic hole area, and the freedom regarding the shape and position of the display frame can be increased.

(Effect of the separate structure of the push button switch and the transmitter body)
In addition, the transmitters of the second and sixth inventions are separated into the transmitter body, a push button switch with a protective plate, and a maintenance door, and the push button switch and maintenance door are provided on the front of the storage case, while the transmitter body is provided within the storage case.Since only the push button switch with a protective cover for the transmitter and the maintenance door are provided on the front of the storage case, the freedom of arrangement of the indicator light and sound hole area is greatly increased, and the size of the storage case can be greatly reduced compared to when the transmitter is provided directly on the front of the storage case, making the entire disaster prevention device even smaller.

(Effect of the relationship between the indicator light and the storage case)
In addition, since the display surface of the indicator light is made flush with the front surface of the storage case or the front surface and side surfaces of the storage case, the display surface of the indicator light is approximately flat along the front surface or the front surface and side surfaces of the storage case, improving the design. Also, by reducing the protrusion of the indicator light from the surface of the storage case, the display can be made thinner, and various display patterns that improve visibility from the front and sides can be easily formed.

(Effect of the relationship between the transmitter and the storage case)
In addition, the exposed height of the top of the exposed part of the transmitter (maintenance door, push button) is made lower than the exposed height of the display surface on the front side of the display surface, which reduces the protrusion of the transmitter operating part from the surface of the storage case, preventing erroneous operation due to contact with people or objects, and is expected to improve the design, etc.

(Seventh invention: Overlap of sound hole area, transmitter arrangement area and indicator light)
Another form of the present invention is a disaster prevention device in which the acoustic hole area, transmitter placement area and indicator light are arranged so that their placement positions at least partially overlap in the up/down or left/right directions (vertical or horizontal) when installed, thereby relaxing constraints such as the space for placing the acoustic hole, transmitter and indicator light, and improving design freedom.

In addition, for example, the indicator light has a display surface on at least one of the left and right side surfaces of the storage case when installed, and the indicator light is provided with an acoustic hole on at least one of the left and right side surfaces and/or on at least one of the top and bottom surfaces of the storage case when installed, thereby ensuring and improving visibility from the side, above, and below.

Note that the disaster prevention equipment storage box is also simply called an equipment storage box.

[Basic Concept of the First Invention]
FIG. 1 is an explanatory diagram showing a first embodiment of a disaster prevention equipment storage box in which position indicator lights and sound holes are concentrated in one place as an example of a disaster prevention device of the present invention, FIG. 2 is an explanatory diagram showing the exploded structure of the disaster prevention equipment storage box, and FIG. 3 is an explanatory diagram showing the position indicator lights removed from the back.

The basic concept of this embodiment is a disaster prevention equipment storage box 10 in which an opening 14a and/or a notch is provided in the position indicator light 14, and at least one of the openings 14a and/or the notch is provided with an acoustic hole 16. The position indicator light 14 and the acoustic hole 16, which function as an alarm unit, are gathered in one place, reducing the installation space and making the disaster prevention equipment storage box 10 smaller, and the transmitter 12, which is the operating unit, is separated from the position indicator light 14 and the acoustic hole 16, which are the alarm units, to prevent confusion for the user.

In addition, even if the acoustic holes 16 and the position indicator lights 14 are placed together in one location, the placement and shape of the position indicator lights 14 are not restricted by the placement of the acoustic holes 16, allowing for a high degree of freedom in the placement and shape of the position indicator lights 14 and improving the design.

In another embodiment of the present invention, a position indicator light is provided surrounding the transmitter, and an acoustic hole is provided in at least one of the gap between the transmitter and the position indicator light, the opening of the position indicator light, and the notch of the position indicator light. This not only improves operability and design to the same extent as the disaster prevention equipment storage box 10 shown in Figure 1, but also further reduces the installation space by arranging the position indicator light, acoustic hole, and transmitter in one place, making it possible to make the disaster prevention equipment storage box even more compact.

In this case, the operation unit and notification unit are placed together in one place, so when the user operates the device, they will not have to worry about which is the operation unit and which is the notification unit.

[First embodiment of disaster prevention equipment storage box: first invention]
(Outline of disaster prevention equipment storage box)
As shown in Fig. 1 (A), in the disaster prevention equipment storage box 10 of the first embodiment, a transmitter 12 is disposed on the underside of the exposed surface of a cover plate 10a that is exposed when the box is installed on a wall or the like, and acoustic holes 16 and position indicator lights 14 are disposed above the transmitter 12. The opening shape, size, number, and arrangement of each acoustic hole 16 are appropriately selected and adjusted in consideration of sound output performance, diffusion performance, design, etc.

The transmitter 12 has a protective plate 18 made of a transparent acrylic plate or the like in the center to turn on the built-in push button switch 20, and a maintenance door 22 with a telephone jack inside.

The position indicator light 14 has a rectangular picture frame 28a, an opening 14a is formed inside the picture frame 28a, and a plurality of acoustic holes 16 are formed on the plate surface located at the opening 14a, and the position indicator light 14 and the acoustic holes 16 are arranged in one place. As shown in FIG. 1(B), the acoustic holes 16 may be arranged on the outside of the picture frame 28a.

In FIG. 1(B), a unit 15 having a position indicator light 14 and an acoustic hole 16 is disposed on a cover plate 10a, so that the area in which the acoustic hole 16 is disposed (acoustic hole area 16a shown by imaginary lines) and the display surface of the position indicator light 14 (here, the front surface of the picture frame display frame 28a) overlap with each other. Here, the center of the acoustic hole area and the center of the picture frame display frame 28a (center of the opening 14a) may be offset so that part of the display surface overlaps with the acoustic hole area when viewed from the front.

As shown in Figure 2, the disaster prevention equipment storage box 10 is made up of a cover plate 10a and a box-shaped main body 10b, and an acoustic device 24 such as a buzzer or bell is placed in a position behind the position indicator light 14 attached to the cover plate 10a and in the main body 10b opposite the position indicator light 14. When the acoustic device 24 is sounded by a local acoustic signal from the receiver, the fire alarm sound is output from the acoustic hole 16 located in the rectangular opening 14a in the frame 28a of the position indicator light 14 shown in Figure 1.

As shown in FIG. 3, the position indicator light 14 is closed by disposing a sealing portion 36 in the opening 14a of the picture frame 28a, and the sealing portion 36 is provided with a plurality of acoustic holes 16 shown in FIG. 1. A cylindrical mounting portion 38 extends from the rear of the sealing portion 36, and the position indicator light 14 can be attached to the cover plate 10a by fitting the cylindrical mounting portion 38 into the mounting hole of the cover plate 10a shown in FIG. 2.

The cylindrical mounting portion 38 is located in front of the acoustic device 24 arranged on the main body 10b, and also functions as an acoustic introduction case that introduces the fire alarm sound generated by the acoustic device 24 and outputs it forward from the acoustic hole 16.

(Structure of Position Indicator Light)
Figure 4 is a cross-sectional view showing the internal structure of the acoustic hole and the position indicator light in Figure 3. As shown in Figure 4, the position indicator light 14 has an annular indicator light case 26 that has a U-shaped cross section and is open to the front. An LED storage section 30 is formed inside the indicator light case 26, and a frame-shaped circuit board 34, for example, is disposed on the bottom side. LEDs 32 that function as light sources are disposed at predetermined intervals on the circuit board 34.

A rectangular picture frame 28a is placed in the front opening of the indicator light case 26. The picture frame 28a uses a diffuse translucent material that emits red light. The diffuse translucent material is a material that receives light from a point light source such as an LED 32 and converts it into surface light. Light from the backlighting of the LEDs 32 arranged in a ring shape at a specified interval on the circuit board 34 is incident on the picture frame 28a using the diffuse translucent material, and the entire display surface of the picture frame 28a is used as the display area (light-emitting area) and emits a substantially uniform red light.

The display surface of the frame 28a is formed as an inclined display surface with the inner periphery protruding slightly forward from the outer periphery, and this inclined display surface improves visibility when the position indicator light 14 is viewed from the side. Note that a curved display surface may be used instead of an inclined display surface.

A rectangular opening 14a is formed on the inside of the indicator light case 26 of the position indicator light 14, and the opening 14a is closed by fitting a sealing part 36. The sealing part 36 is a box-shaped member with a sealing surface 36a at the front, and as shown in FIG. 1, a plurality of acoustic holes 16 are formed in the acoustic hole area 16a (area surrounded by a two-dot chain line in the figure) on the sealing surface 36a, and a cylindrical mounting part 38 extends from the rear of the sealing part 36. The cylindrical mounting part 38 is fitted into a mounting hole 35 formed in the cover plate 10a, allowing the position indicator light 14 to be attached and fixed to the cover plate 10a.

The rear opening of the cylindrical mounting portion 38 faces the acoustic device 24 arranged on the main body 10b shown in FIG. 2, and functions as an acoustic introduction case that introduces the fire alarm sound from the acoustic device 24 into the inside of the sealing member 36 and outputs it to the outside through the acoustic hole 16 formed in the sealing surface 36a.

The mounting structure of the position indicator light 14 to the cover plate 10a is not limited to that shown in FIG. 4, and any suitable mounting structure can be used.

In this way, in the first embodiment, the position indicator light 14 and the acoustic hole 16 are arranged together in one place by forming an acoustic hole 16 in the rectangular opening 14a located inside the picture frame 28a of the position indicator light 14. This not only reduces the installation space and makes the disaster prevention equipment storage box 10 smaller, but also allows the position indicator light 14, which functions as an alarm unit, and the acoustic hole 16 to be arranged together in one place, preventing the operator from becoming confused as in the case of the conventional case in which the transmitter 12, which functions as an operating unit, and the position indicator light, which functions as an alarm unit, are integrated, improving operability in emergencies such as fires.

In addition, by making the outer edge of the position indicator light 14 into a rectangular ring shape using the frame 28a, a clear outline is given to the acoustic hole arrangement section where the acoustic holes 16 are arranged, which also enhances the design.

(Transmitter decorative frame)
Fig. 5 is an explanatory diagram showing a disaster prevention equipment storage box with a decorative frame provided on the transmitter side of Fig. 1. As shown in Fig. 5, this embodiment is characterized in that a decorative frame 40 is provided on the plate surface surrounding the periphery of the transmitter 12 arranged on the cover plate 10a by a decorative frame member, paint, sealing tape, etc., in addition to the disaster prevention equipment storage box 10 of the first embodiment shown in Fig. 1.

For this reason, by making the outer edge of the position indicator light 14 into a rectangular ring shape using the frame 28a, a clear outline is given to the acoustic hole arrangement section where the acoustic holes 16 are arranged, and by providing a decorative frame 40 of the same shape to the transmitter 12, a clear outline is also given, improving the cohesiveness of the disaster prevention equipment storage box 10 of this embodiment when it is installed on a wall surface or the like, and further enhancing the design.

[Second embodiment of disaster prevention equipment storage device]
Fig. 6 is an explanatory diagram showing a second embodiment of the disaster prevention equipment storage box. As shown in Fig. 6, the disaster prevention equipment storage box 10 of this embodiment has a lattice display frame 28b on the position indicator light 14, and a plurality of sound holes 16 are provided in each of, for example, four openings partitioned by the lattice display frame 28b. The rest of the structure is the same as that of the first embodiment, and the same effects can be obtained.

In addition, in this embodiment, the position indicator light 14 is provided with a lattice display frame 28b, which increases the display area (the display area of the display surface) and improves visibility, while also creating a strong impression in terms of design.

[Third embodiment of disaster prevention equipment storage device]
Fig. 7 is an explanatory diagram showing a third embodiment of the disaster prevention equipment storage box. As shown in Fig. 7, the disaster prevention equipment storage box 10 of this embodiment has an annular display frame 28c on the position indicator light 14, and a circular opening partitioned by the annular display frame 28c has a plurality of sound holes 16. The rest of the structure is the same as that of the first embodiment, and the same effects can be obtained.

In addition, in this embodiment, the position indicator light 14 is provided with an annular display frame 28c, which allows it to be well integrated with the circular transmitter 12 and enhances the design of the disaster prevention equipment storage box 10 of this embodiment.

In this embodiment, in addition to the same improved operability and design as the first embodiment, the transmitter 12, position indicator light 14, and sound hole 16 are all concentrated in one location, further reducing the installation space, making it possible to further miniaturize the disaster prevention equipment storage box.

In addition, the display frame of the position indicator light 14 in this embodiment may also be in the annular shape shown in Figure 7, Figure 9, or Figure 10.

[Fire hydrant equipment]
FIG. 12 is an explanatory diagram showing an embodiment of a fire hydrant device in which a position indicator light and a sound hole are arranged in one place.

As shown in FIG. 12, the fire hydrant device 50 of this embodiment has a fire hydrant door 54 on the front of a metal storage box 52 that can be opened and closed freely, a notification panel 56 on top of the fire hydrant door 54, a transmitter 12 on the cover plate 10a of the notification panel 56, and an audio hole 16 and a position indicator light 14 all arranged in one place. A hose with a nozzle is stored inside the fire hydrant door 54.

The position indicator light 14 is the same as the position indicator light 14 provided on the disaster prevention equipment storage box 10 in Figure 1, and has a rectangular frame 28a, an opening 14a is formed inside the frame 28a, and an acoustic hole 16 is formed on the plate surface located at the opening 14a.

In this embodiment, the location indicator light 14 and the sound hole 16, which function as the alarm unit, are installed together in one place, reducing the installation space of the notification panel 56 installed on the fire hydrant box 50, and the transmitter 12, which is the operation unit, is separated from the location indicator light 14 and sound hole 16, which are the alarm unit, to prevent confusion among users.

In addition, even if the acoustic holes 16 and the position indicator lights 14 are placed together in one location, the placement and shape of the position indicator lights 14 are not restricted by the placement of the acoustic holes 16, allowing for a high degree of freedom in the placement and shape of the position indicator lights 14 and improving the design.

In addition, by making the outer edge of the position indicator light 14 into a rectangular ring shape using the frame 28a, a clear outline is given to the acoustic hole arrangement section where the acoustic holes 16 are arranged, thereby enhancing the design.

The notification panel 56 in FIG. 12 may be provided with the same position indicator light 14 as that provided on the disaster prevention equipment storage box 10 in FIG. 6, FIG. 7, FIG. 8, FIG. 9, or FIG. 10.

Figure 13 is an explanatory diagram showing an embodiment of a fire hydrant device in which a transmitter, a position indicator light, and an audio hole are all located in one place.

As shown in FIG. 13, the fire hydrant device 50 of this embodiment has a transmitter 12, a position indicator light 14, and a sound hole 16 all concentrated in one location on the cover plate 10a of the notification panel 56 located on the top of the fire hydrant door 54.

The position indicator light 14 is the same as the position indicator light 14 provided on the disaster prevention equipment storage box 10 in FIG. 11, and the reporting panel 56 is provided with the position indicator light 14, which is made up of a divided annular display frame 28g that is divided into four parts on the left, right, top and bottom so as to surround the transmitter 12, and acoustic holes 16 are provided in the gap between the transmitter 12 and the position indicator light 14, the opening of the position indicator light 14, and the notch of the position indicator light 14.

In this embodiment, in addition to the same improved operability and design as in FIG. 12, the installation space can be further reduced by arranging the transmitter 12, the position indicator light 14, and the sound hole 16 in one place.

[Embodiment in which position indicator lights and sound holes are centrally arranged on the cover plate]
FIG. 14 is an explanatory diagram showing an embodiment of a disaster prevention equipment housing box in which position indicator lights and sound holes are arranged in a concentrated manner on the cover plate.

This structure simplifies the structure in which the position indicator light 14 and the acoustic hole 16 are centrally located. Of course, the same can be applied to a fire hydrant device.

[Embodiment of disaster prevention equipment housing box with sound hole in position indicator light]
Figure 15 is an explanatory diagram showing an embodiment of a disaster prevention equipment storage box in which an acoustic hole is provided in a position indicator light, Figure 16 is an explanatory diagram showing the position indicator light in Figure 15 and its internal structure, and Figure 17 is an explanatory diagram showing the front and top cross section of the position indicator light in Figure 15.

As shown in FIG. 15, the disaster prevention equipment storage box 10 of this embodiment has a transmitter 12 disposed below the exposed surface of the cover plate 10a, and a circular position indicator light 14 disposed above the transmitter 12, with an acoustic hole 16 provided in the position indicator light 14.

As shown in Figures 16(A) and 17(A), the circular display frame 28h of the position indicator light 14 has acoustic holes 16 arranged in a double annular configuration in the acoustic hole area 16a, and as shown by dotted lines in Figures 15 and 17(A), LEDs 32 are provided inside the circular display frame 28h, and the LEDs 32 are provided in a double annular configuration in the center of the position indicator light 14 and on its outer side. In addition, a mounting cylinder 38 is provided behind the circular display frame 28h, allowing it to be fitted and fixed from the front into the mounting hole 35 of the cover plate 10a.

The internal structure of the position indicator light 14 is shown in Figure 16(B) and Figure 17(B). Note that Figure 17(B) is a plan cross-sectional view of the position indicator light 14 taken along the X-X cross section of Figure 16(B).

As shown in Figures 16(B) and 17(B), the circular display frame 28h uses a red diffuse translucent material, has a cylindrical mounting portion 38 formed integrally at the back, and is connected to an outer peripheral rib 60 that leads to the cylindrical mounting portion 38 toward the rear side, and annular ribs 62a, 62b, and 62c are arranged concentrically on the inside of the outer peripheral rib 60 and the annular ribs 62a, 62b, and LED storage portions 64a, 64b, and 64c are formed between the outer peripheral rib 60 and the annular ribs 62a, 62b, and in the center.

Each of the annular ribs 62a, 62b has a plurality of acoustic holes formed therethrough. A circular circuit board 34 is disposed at the bottom of the cylindrical mounting portion 38 behind the circular display frame 28h, and an opening hole 34a is formed at a position corresponding to the acoustic hole 16 of the circuit board 34, which is connected to the acoustic hole 16 and penetrates the inside, so that sound from the acoustic device 24 disposed on the main body 10b is output to the outside through the acoustic hole 16 of the position indicator light 14. The acoustic device 24 may be directly attached to the cylindrical mounting portion 38.

As shown in FIG. 17B, a plurality of LEDs 32 are arranged on the circuit board 34 so as to correspond to the concentrically arranged LED storage sections 64a, 64b, and 64c. For example, one LED 32 is arranged in the central LED storage section 64c, and eight LEDs are arranged at 45° intervals in each of the outer concentric LED storage sections 64b and 64a.

By driving the multiple LEDs 32 arranged on the circuit board 34 to emit light in this manner, the light from the LEDs 32 enters the circular display frame 28h made of a diffusive translucent material, causing the entire surface of the position indicator light 14 to emit a substantially uniform red light.

In this embodiment, by providing an acoustic hole 16 in the position indicator light 14, in addition to improving operability and design in the same way as in the first embodiment, it is not necessary to process and form an acoustic hole in the cover plate 10a of the disaster prevention equipment storage box 10, which simplifies the structure accordingly.

The arrangement of the acoustic holes 16 and the LEDs 32 relative to the circular display frame 28h of the position indicator light 14 is one example and is not limited to this. For example, the acoustic holes 16 and the LEDs 32 may be arranged alternately in a radial pattern.

In addition, the embodiments of Figures 1, 5 to 10 may also be structured so that sound holes 16 are provided in the display frames provided in each embodiment. This embodiment may also be provided in a fire hydrant device 50 as shown in Figures 12 and 13.

[Embodiment in which the transmitter, position indicator light, and sound hole of the disaster prevention equipment storage box are centrally arranged]
FIG. 18 is an explanatory diagram showing another embodiment of a disaster prevention equipment housing box in which a transmitter, a position indicator lamp, and a sound hole are arranged in one place.

As shown in FIG. 18, in this embodiment, a position indicator light 14 is provided on the cover plate 10a of the disaster prevention equipment storage box 10, which is divided at two points on the left and right to surround the transmitter 12 into two divided annular display frames 28i, and multiple acoustic holes 16 are provided on the outer and inner sides of the divided annular display frames 28i of the position indicator light 14.

In this embodiment, in addition to the same improved operability and design as the first embodiment, the installation space is further reduced by consolidating the transmitter 12, position indicator light 14, and acoustic hole 16 in one location, and it is no longer necessary to process and form an acoustic hole in the cover plate 10a of the disaster prevention equipment storage box 10, which simplifies the structure accordingly.

The shape of the display frame with the acoustic hole 16 of the position indicator light 14 in this embodiment can of course also be provided in the position indicator light 14 in FIG. 11, similar to FIG. 18, with the acoustic hole 16. The shape of the display frame of the position indicator light 14 can be applied to other embodiments and other cases. This embodiment may also be provided in a fire hydrant device 50 as shown in FIG. 13.

[Embodiment of disaster prevention equipment housing box with sound hole in position indicator light]
Figure 19 is an explanatory diagram showing another embodiment of a disaster prevention equipment storage box in which an acoustic hole is provided in the position indicator light, and Figure 20 is an explanatory diagram showing a cross-section of the position indicator light in Figure 19, with Figure 20(A) showing the A-A cross-section and Figure 20(B) showing the B-B cross-section.

As shown in FIG. 19, the disaster prevention equipment storage box 10 of this embodiment has a transmitter 12 disposed below the exposed surface of the cover plate 10a, and a rectangular position indicator light 14 disposed above the transmitter 12, with an acoustic hole 16 (indicator light side acoustic hole) provided in the position indicator light 14.

As shown in Figures 19 and 20 (A), the rectangular display frame 28j of the position indicator light 14 has, for example, three sound holes 16 that open in a cone shape on the front side, arranged in three rows and three columns, and sound holes 16a (cover plate side sound holes) are provided at positions corresponding to the sound holes 16 of the cover plate 10a, so that sound from the acoustic device 24 arranged on the main body 10b is output to the outside through the sound holes 16a of the cover plate 10a and the sound holes 16 of the position indicator light 14. In other words, in this case, the sound holes 16 (indicator light side sound holes) also correspond to the openings.

As shown by the dotted line in FIG. 19, LEDs 32 are provided behind the rectangular display frame 28j, for example, in two rows and two columns, positioned between the acoustic holes 16. As shown in FIG. 20(B), a light-transmitting hole 70 is provided in the cover plate 10a located on the back side of the rectangular display frame 28j, a circuit board 34 is disposed on the back side of the cover plate 10a, and the LEDs 32 are disposed on the circuit board 34 at positions corresponding to the light-transmitting hole 70 of the cover plate 10a. By driving the LEDs 32 to emit light, the light from the LEDs 32 enters the rectangular display frame 28j using a diffuse light-transmitting member through the light-transmitting hole 70, causing the entire surface of the position indicator light 14 to emit a substantially uniform red light.

In this embodiment, by providing an acoustic hole that communicates with the position indicator light 14 and the cover plate 10a, in addition to improving operability and design like the first embodiment, it is possible to simplify the structure by consolidating the position indicator light 14 and the acoustic hole 16 in one location.

The center of the rectangular display frame 28j and the arrangement area of the cover plate side acoustic hole may be offset, for example, vertically. In this case, the cover plate side acoustic hole and the indicator light side acoustic hole may be provided in corresponding positions. In this case, the display surface and the acoustic hole area will partially overlap when viewed from the front.

The arrangement of the acoustic hole 16 and the LED 32 relative to the display surface of the rectangular display frame 28j of the position indicator light 14 in this embodiment is merely an example, and is not limited to this and may be arranged as appropriate.

In addition, for the embodiments of Figs. 1, 5 to 10, the position indicator light 14 and the sound hole 16 provided in each embodiment may be provided in the cover plate 10a. This embodiment may also be provided in a fire hydrant device 50 as shown in Figs. 12 and 13. Furthermore, the configurations of Figs. 19 and 20 may be combined with the configurations of other embodiments.

[Embodiment of disaster prevention equipment storage box with acoustic path formed in position indicator light: Third invention]
FIG. 21 is an explanatory diagram showing an embodiment of a disaster prevention equipment housing box in which an acoustic path is formed in a position indicator light, and FIG. 22 is an explanatory diagram showing a cross section of the position indicator light in FIG.

As shown in FIG. 21, the disaster prevention equipment storage box 10 of this embodiment has a transmitter 12 disposed below the exposed surface of the cover plate 10a, and a rectangular position indicator light 14 disposed above it.

As shown in FIG. 22, the rectangular display frame 28k of the position indicator light 14 has a protrusion 77 that is rectangular in cross section and extends conically behind the front rectangular frame, and is fixed to the front of the cover plate 10a by screws 62 via spacers 78 so that the protrusion 77 is positioned in a mounting hole 75 formed in the cover plate 10a with a gap between it and the front (exposed surface) of the cover plate 10a, thereby forming an acoustic path 72 between the cover plate 10a and the rectangular display frame 28k, leading from the gap in the mounting hole 75 to the outside. The acoustic path 72 achieves the same function as forming an acoustic hole.

As a result, sound from the acoustic device 24 mounted on the main body 10b passes through the gap in the mounting hole 75, through the acoustic path 72 formed behind the rectangular display frame 28k, and is output to the outside via the path indicated by the arrow 76.

In addition, an LED storage section 74 is formed in a protrusion 77 formed on the back of the rectangular display frame 28k, and an LED 32 mounted on a circuit board 34 is provided. By driving the LED 32 to emit light, the light from the LED 32 enters the rectangular display frame 28k, which uses a diffuse translucent material, and emits a substantially uniform red light over the entire surface of the position indicator light 14.

In this way, in this embodiment, by forming an acoustic path 72 behind the position indicator light 14, a sound passage equivalent to forming multiple acoustic holes is secured, and sound can be output efficiently. In addition, the acoustic path 72 is hidden by the position indicator light 14 and cannot be seen, which provides a new design for the disaster prevention equipment storage box 10 without acoustic holes, and makes it possible to greatly improve the design.

In order to adjust the sound output and diffusion performance, it is also possible to provide an acoustic hole in the rectangular display frame 28k of the position indicator light 14. Furthermore, it is also possible to provide an acoustic hole in the cover plate 10a outside the display frame, as in the embodiment of FIG. 1(B).

The arrangement of the acoustic path 72 and the LED 32 formed behind the position indicator light 14 in this embodiment is one example, and is not limited to this, and may be arranged as appropriate. This embodiment may also be provided on a fire hydrant device 50 as shown in Figures 12 and 13. The display frame may also be other than rectangular, for example, circular. Of course, the protrusion may also be other shapes.

[Embodiment of a disaster prevention equipment storage box with an acoustic horn formed on a position indicator light: Fourth invention]
FIG. 23 is an explanatory diagram showing an embodiment of a disaster prevention equipment housing box in which an acoustic horn is formed on a position indicator light, and FIG. 24 is an explanatory diagram showing a central cross section of the position indicator light in FIG.

As shown in FIG. 23, in the disaster prevention equipment storage box 10 of this embodiment, the transmitter 12 is disposed below the exposed surface of the cover plate 10a, and a rectangular position indicator light 14 is disposed above it. A rectangular acoustic hole 16 is formed in the center of the position indicator light 14, and an acoustic horn 80 that opens in a cone shape is formed around the acoustic hole 16.

As shown in FIG. 24, the rectangular display frame 28m of the position indicator light 14 has a rectangular cross-sectional protrusion 82 formed at the rear center, and the acoustic hole 16 penetrates the center of the rectangular cross-sectional protrusion 82, and the front side of the acoustic hole 16 gradually widens, forming an acoustic horn 80 on the front side of the rectangular display frame 28m. Therefore, sound from the acoustic device 24 placed on the main body 10b passes through the acoustic hole 16 and is output and diffused to the outside by the acoustic horn 80.

A light-transmitting hole 70 is provided in the cover plate 10a located on the back surface of the rectangular display frame 28m, a circuit board 34 is disposed on the back surface of the cover plate 10a, and an LED 32 is disposed on the circuit board 34 at a position corresponding to the light-transmitting hole 70 of the cover plate 10a. By driving the LED 32 to emit light, the light from the LED 32 enters the rectangular display frame 28m using a diffuse light-transmitting material through the light-transmitting hole 70, causing the entire surface of the position indicator light 14 to emit a substantially uniform red light.

In this way, in this embodiment, by forming an acoustic hole 16 and an acoustic horn 80 in the position indicator light 14, in addition to reducing the installation space, the sound from the acoustic device 24 can be efficiently output and diffused to the outside, and the formation of the acoustic horn 80 can greatly improve the design.

In order to adjust the sound output and diffusion performance, it is also possible to provide an acoustic hole in the rectangular display frame 28m of the indicator light 14. Furthermore, as in the embodiment of FIG. 1(B), it is also possible to provide an acoustic hole in the cover plate 10a outside the display frame. In this case, when providing an acoustic hole in the display frame, an acoustic hole is also provided in the corresponding position of the cover plate 10a.

The shape and arrangement of the acoustic hole 16 and acoustic path 72 formed in the position indicator light 14 in this embodiment are merely examples, and are not limited to these, and may be of any suitable shape and arrangement. This embodiment may also be provided in a fire hydrant device 50 as shown in Figures 12 and 13. The display frame may also be other than rectangular, for example, circular. Of course, the protrusion may also be of other shapes.

[Embodiment of a disaster prevention equipment storage box having an acoustic path and an acoustic horn formed in a position indicator lamp]
FIG. 25 is an explanatory diagram showing an embodiment of a disaster prevention equipment housing box in which an acoustic path and an acoustic horn are formed in a position indicator light, and FIG. 26 is an explanatory diagram showing a central cross section of the position indicator light in FIG.

This embodiment is characterized by a combination of the structure in which an acoustic path 72 is formed behind the position indicator light 14 shown in the embodiment of Figures 21 and 22, and the structure in which an acoustic hole 16 and an acoustic horn 80 are provided in the position indicator light 14 shown in the embodiment of Figures 23 and 24.

As shown in FIG. 25, in the disaster prevention equipment storage box 10 of this embodiment, the transmitter 12 is disposed below the exposed surface of the cover plate 10a, and a rectangular position indicator light 14 is disposed above it. A rectangular acoustic hole 16 is formed in the center of the position indicator light 14, and an acoustic horn 80 that opens in a cone shape is formed around the acoustic hole 16.

That is, as shown in FIG. 26, the rectangular display frame 28n of the position indicator light 14 has a rectangular acoustic hole 16 penetrating through a protrusion 82 with a rectangular cross section formed at the rear center, and the front side of the acoustic hole 16 gently widens into a cone shape, forming an acoustic horn 80 on the front side of the rectangular display frame 28n.

Also, as shown in FIG. 26, the rectangular display frame 28n of the position indicator light 14 is fixed to the front surface of the cover plate 10a by screws 26 via spacers 78 so that the protrusion 82 is positioned in the mounting hole 75 formed in the cover plate 10a with a gap between it and the exposed surface of the cover plate 10a. This forms an acoustic path 72 between the cover plate 10a and the rectangular display frame 28n, leading from the gap in the mounting hole 75 to the outside.

A light-transmitting hole 70 is provided in the cover plate 10a located on the back surface of the rectangular display frame 28n, a circuit board 34 is disposed on the back surface of the cover plate 10a, and an LED 32 is disposed on the circuit board 34 at a position corresponding to the light-transmitting hole 70 of the cover plate 10a. A rectangular opening 34a is also formed in the circuit board 34, and a protrusion 82 formed behind the rectangular display frame 28n is positioned in the rectangular opening 34a with a gap therebetween.

When the LED 32 on the circuit board 34 is driven to emit light, the light from the LED 32 enters the rectangular display frame 28n, which is made of a diffuse light-transmitting material, through the light-transmitting hole 70, causing the entire surface of the position indicator light 14 to emit a substantially uniform red light.

The sound from the acoustic device 24 arranged on the main body 10b passes through the acoustic hole 16 formed in the center of the rectangular display frame 28n, and is output and diffused to the outside by the acoustic horn 80. At the same time, the sound from the acoustic device 24 passes through the gap of the rectangular opening 34a of the circuit board 34, the gap of the mounting hole 75 of the cover plate 10a, the acoustic path 72 formed behind the rectangular display frame 28n, and is output to the outside via the path indicated by the arrow 76.

In this way, in this embodiment, by forming an acoustic hole 16 and an acoustic horn 80 in the position indicator light 14 and forming an acoustic path 72 behind the position indicator light 14, in addition to reducing the installation space, the sound from the acoustic device 24 can be efficiently output to the outside, and the formation of the acoustic horn 80 can greatly improve the design.

The shapes and arrangements of the acoustic horn 80 and acoustic path 72 formed on the position indicator light 14 in this embodiment, and the acoustic path 72 formed behind the position indicator light 14 are merely examples, and are not limited to these, and may be of any suitable shape and arrangement. This embodiment may also be provided on a fire hydrant device 50 as shown in Figures 12 and 13. The protrusion 82 may also have a different shape.

[Embodiment of a disaster prevention equipment housing box having an acoustic path formed inside a position indicator light]
FIG. 27 is an explanatory diagram showing another embodiment of a disaster prevention equipment storage box in which an acoustic path is formed in a position indicator light, and FIG. 28 is an explanatory diagram showing a cross section (cross section CC) of the position indicator light in FIG.

As shown in FIG. 27, the disaster prevention equipment storage box 10 of this embodiment has a transmitter 12 disposed below the exposed surface of the cover plate 10a, and a rectangular position indicator light 14 disposed above it.

As shown in FIG. 28, the rectangular display frame 28p of the position indicator light 14 has a protrusion 77 that is rectangular in cross section and extends in a pyramidal shape behind the front rectangular frame, and an acoustic path 76 is formed in a direction that spreads in a pyramidal shape from the back surface to the front surface, and as shown in FIG. 27, an acoustic hole 16 is formed on the surface of the rectangular display frame 28p, opening in a frame-like shape and splitting into left, right, top and bottom.

The rectangular display frame 28p is fixed to the front surface of the cover plate 10a with screws 62 so that the protrusion 77 is positioned in the center of the mounting hole 75 formed in the cover plate 10a.

An LED storage section 74 is formed in a protrusion 77 formed behind the rectangular display frame 28p, and an LED 32 is provided on a circuit board 34 arranged behind the protrusion 77. An opening 34b is also formed in the circuit board 34 arranged behind the protrusion 77, and an acoustic path 72 is open to the rear. The opening 34b constitutes an acoustic hole.

In addition, a light-transmitting hole 70 is provided in the cover plate 10a at a position adjacent to the rear side of the rectangular display frame 28p, and another circuit board 34 is arranged on the rear side of the cover plate 10a, and an LED 32 is arranged on this circuit board 34 at a position corresponding to the light-transmitting hole 70 of the cover plate 10a.

By driving the LEDs 32 arranged in this manner to emit light, the light from the LEDs 32 enters the rectangular display frame 28p made of a diffusive translucent material, causing the entire surface of the position indicator light 14 to emit a substantially uniform red light.

Sound from the acoustic device 24 arranged in the main body 10b passes through the acoustic path 72 formed inside the rectangular display frame 28p from the opening 34b of the circuit board 34, and is output to the outside from the acoustic hole 16 opening on the front surface of the rectangular display frame 28p.

In this way, in this embodiment, by forming an acoustic path 72 inside the position indicator light 14, a sound passage is secured, and sound can be output and diffused efficiently. In addition, by opening the acoustic hole 16 in a frame-like shape divided into four places within the rectangular display frame 28p of the position indicator light 14, a new design can be obtained and the design can be greatly improved.

The arrangement of the acoustic path 72 and the LED 32 formed inside the position indicator light 14 in this embodiment is one example, and is not limited to this, and may be arranged as appropriate. This embodiment may also be provided in a fire hydrant device 50 as shown in Figures 12 and 13. The display frame may also be other than rectangular, for example, circular. Of course, the protrusion may also be other shapes.

In addition, the indicator light with an acoustic path of this embodiment may be positioned so that an acoustic path is formed between it and the cover plate, as in the embodiment of Figures 25 and 26.

As shown in FIG. 29, the disaster prevention equipment storage box 10 of this embodiment is configured with a cover plate 10a and a main body 10b, and is installed on a wall or the like so that the cover plate 10a is exposed.

The transmitter 12 is located on the front surface 13a of the cover plate 10a, which is exposed when the disaster prevention equipment storage box 10 is installed on a wall or the like, and the position indicator light 14 and the acoustic hole area 16a (area surrounded by a two-dot chain line in the figure) with the acoustic hole 16 opened are located adjacent to the transmitter 12.

The transmitter 12 has a protective plate 18 made of a transparent acrylic plate or the like at its bottom center to turn on the built-in push button switch 20, and above that, a maintenance door 22 with a telephone jack inside.

The disaster prevention equipment storage box 10 is generally installed on a wall or the like with the position indicator lights 14, the sound hole area 16a, and the transmitters 12 arranged in a vertical direction, for example with the position indicator lights 14 on the top (ceiling side) and the transmitters 12 on the bottom (floor side).

The position indicator light 14 has a roughly gate-shaped display frame 28q that extends from the top of the front surface 13a of the cover plate 10a to both the left and right side surfaces 13b, so that when the disaster prevention equipment storage box 10 is installed, the position indicator light 14 has a display surface 15 on the front surface 13a and side surfaces 13b of the storage case.

In addition, on the front surface 13a, the area surrounded on the upper side and on both the left and right sides by the display frame 28q of the position indicator light 14 becomes the acoustic hole area 16a equipped with the acoustic hole 16, so that the position indicator light 14 and the acoustic hole area 16 are concentrated in one place.

In this embodiment, the display frames 28q of the roughly gate-shaped position indicator lights 14 are concentrated in one place, surrounding the acoustic hole area 16a, which reduces the dimensions of the concentrated position indicator lights 14, acoustic hole area 16a, and transmitter 12 in the arrangement direction, making it possible to miniaturize the disaster prevention equipment storage box 10.

In addition, the display surface 15 on the front surface 13a of the position indicator light 14 maintains visibility from the front when the disaster prevention equipment storage box 10 is installed, and at the same time, the display surface 15 on the side surface 13b improves visibility from the side, improving the visibility of the indicator light as a whole and providing a new design, thereby enhancing the design.

In this embodiment, a display surface is also provided on the top surface of the storage case, so that visibility from above can be ensured, for example, when the disaster prevention equipment storage box 10 is installed at a relatively low position or when the disaster prevention equipment storage box 10 can be seen from above.

Figure 30 is an explanatory diagram showing the exploded structure of the disaster prevention equipment storage box of Figure 29. As shown in Figure 30, the storage case of the disaster prevention equipment storage box 10 is composed of a cover plate 10a and a box-shaped main body 10b, and an acoustic device 24 such as a buzzer or bell is placed in a position opposite to the acoustic hole area 16a formed in the cover plate 10a and in the main body 10b behind the acoustic hole area 16a. When the acoustic device 24 is sounded by a local acoustic signal from a separately installed fire receiver, the fire alarm sound is output from the acoustic hole 16 shown in Figure 29 (A).

A corresponding recess 17 is formed at the transmitter placement position on the front surface 13a of the cover plate 10a, and the transmitter 12 is incorporated into the corresponding recess 17, with the front top 12a of the transmitter 12 protruding from the front surface 13a of the cover plate 10a by a few millimeters.

In this embodiment, the display frame 28q is gate-shaped and surrounds the upper and left and right sides of the periphery of the acoustic hole area 16a, but it may also surround the lower side.

Figure 31 is an explanatory diagram showing another embodiment of a disaster prevention equipment storage box in which a display surface of a display light that encloses part of the sound hole area in a gate shape is provided on the front and side, with Figure 31 (A) showing the front and Figure 31 (B) showing the side.

The disaster prevention equipment storage box 10 of this embodiment shown in Figure 31 is characterized in that, in addition to the embodiment of Figure 29, an acoustic hole 16 (indicator light side acoustic hole) that communicates with the acoustic hole 16 (cover plate side acoustic hole) of the cover plate 10 is provided in the indicator frame 28q of the position indicator light 14 to form an acoustic hole area 16b, and is otherwise the same as the embodiment of Figure 29.

Here, the acoustic hole area as a whole is made up of both acoustic hole area 16a and acoustic hole area 16b, so in this embodiment, the position indicator light 14 and a part of the acoustic hole area (acoustic hole area 16b) are arranged to overlap.

The indicator light side acoustic hole also corresponds to an opening, and multiple cover plate side acoustic holes may be arranged for one opening.

By providing the acoustic hole area 16b in the display frame 28q of the position indicator light 14 in this way, the display frame 28q is not restricted by the arrangement of the acoustic hole area 16a, and the degree of freedom regarding the shape and arrangement of the display frame 28g can be increased.

In addition, in this embodiment, the display frame 28q is gate-shaped and surrounds the upper and left and right sides of the acoustic hole area 16a, but it may also surround the lower side of the display frame 28q. Furthermore, a part of the acoustic area 16a may be positioned outside the outer periphery of the display frame 28q of the position indicator light 14, for example, on the transmitter 12 side as shown in FIG. 32.

Figure 33 is an explanatory diagram showing an embodiment of a disaster prevention equipment storage box in which the display frames of the position indicator lights are arranged on both the left and right sides of the acoustic hole area, and display surfaces are provided on the front and side of the storage case. As shown in Figure 33, the district indicator lights 14 of this embodiment are arranged so that the display frames 28r are separated to the left and right and sandwich the acoustic hole area 16a, which is equipped with the acoustic holes 16 arranged on the front surface 13a of the cover plate 10a, from both sides, thereby consolidating the position indicator lights 14 and the acoustic hole area 16a in one location.

The display frames 28r arranged on both sides of the sound hole area 16a have display surfaces 15 on the front 13a and side 13b of the storage case of the disaster prevention equipment storage box 10. Other than that, it is the same as the embodiment in Figure 29.

By integrating the display frames 28r of the position indicator lights 14 in one location so that they sandwich the acoustic hole area 16a on both the left and right sides, the dimensions of the integrated position indicator lights 14, acoustic hole area 16a, and transmitter 12 in the arrangement direction are reduced, making it possible to miniaturize the disaster prevention equipment storage box 10.

In addition, when the disaster prevention equipment storage box 10 is installed, visibility from the front is maintained by the display surface 15 on the front surface 13a of the display frame 28r provided on the position indicator light 14, and at the same time, visibility from the side is improved by the display surface 15 on the side portion 13b of the display frame 28r, improving the visibility of the indicator light as a whole, while also providing a new design and enhancing the design.

In addition, even in this embodiment, a display surface is provided on the top surface of the storage case, so that visibility from above can be ensured, for example, when the disaster prevention equipment storage box 10 is installed at a relatively low position or when the disaster prevention equipment storage box 10 can be seen from above.

The relationship between the front display width W1 and the side display width W2 of the display frame 28r arranged separately on both the left and right sides of the cover plate 10a may be the same as the front display width W1 and the side display width W2, or, for example, if visibility from the front is to be ensured, the front display width W1 may be made larger than the side display width W2, and, for example, if visibility from the side is to be ensured, the side display width W2 may be made larger than the front display width W1. There is no restriction on the relationship between the front display width W1 and the side display width W2. This also applies to the relationship between the display widths of the front (left and right parts of the gate shape) and the sides of the display frame 28q shown in FIG. 29, and the relationship between the display widths of the front (upper part of the gate shape) and the top surface of the display frame 28q.

[Embodiment of a disaster prevention equipment storage box with indicator lights arranged on the front and sides: 6th invention]
Figure 34 is an explanatory diagram showing an embodiment of a disaster prevention equipment storage box in which the transmitter, position indicator light and sound hole area are concentrated in one location, and the display frame of the indicator light is arranged so that it has a display surface on the front, left and right side surfaces, top and bottom of the storage case, Figure 34 (A) shows the front, Figure 34 (B) shows the side, and Figure 34 (C) shows a plan view.

As shown in FIG. 34, the storage case of the disaster prevention equipment storage box 10 of this embodiment is composed of a cover plate 10a and a box-shaped main body 10b, and the transmitter placed in the disaster prevention equipment storage box 10 is separated into a push button switch 20, a maintenance door 22, and a transmitter main body 12b, and the transmitter main body 12b is placed inside the main body 10b of the storage case, and the push button switch 20 and the maintenance door 22 separated from the transmitter main body 12b are exposed and placed in the center of the front surface 13a of the cover plate 10a.

The exposed height of the exposed parts of the push button switch 20 and the maintenance door 22, for example the height of the tops of the push button switch 20 and the maintenance door 22, is set to be equal to or less than the exposed height of the display surface on the front surface 13a side of the position indicator light 14. The front surface 13a and the display surface on the front side, the exposed tops of the push button switch 20 and the maintenance door 22 may be flush with each other. Of course, the display surfaces on both side surfaces 13b and the side surfaces, and the top and bottom surfaces and the top and bottom display surfaces may also be flush with each other, as shown in FIG. 33.

The push button switch 20 has a protective plate 18 and a switch button arranged inside a rectangular switch cover, and is connected to the transmitter body 12b by a signal line. In addition, a telephone jack is arranged inside the maintenance door 22, and is connected to the transmitter body 12b by a signal line.

The position indicator light 14 has a rectangular display frame 28s that surrounds the transmitter push button switch 20 and maintenance door 22 exposed on the front surface 13a of the cover plate 10a and extends to both the left and right side surfaces 13b of the cover plate 10a, so that the position indicator light 14 has a display surface 15 on the front surface 13a and side surfaces 13b of the storage case of the disaster prevention equipment storage box 10.

In addition, in this embodiment, the display frame 28a also has display surfaces on the upper surface 13c and the lower surface 13d of the cover plate 10a. As a result, the display frame 28s of the position indicator light 14 in this embodiment is formed around the entire periphery of the front surface and the upper, lower, left and right surfaces of the cover plate 10a.

The push button switch 20 is located in the center of the front surface 13a of the cover plate 10a, and the display frame 28s of the position indicator light 14 is located around the maintenance door 22. The sound hole area 16a is provided with sound holes 16 in four locations, for example, on the top, bottom, left and right.

As shown by the dotted lines, LEDs 32 are appropriately positioned behind the display frame 28s, which is located on the front surface 13a of the cover plate 10a, except for the acoustic hole area 16a, and the backlighting of the display frame 28s causes the entire surface of the display frame 28s, including the front surface 13a, the left and right side surfaces 13b, the top surface 13c, and the bottom surface 13d, to emit a substantially uniform red light.

The push button switch 20 and maintenance door 22 separated from the transmitter body 12b can be placed in a smaller space than the transmitter 12 shown in FIG. 29, which has the push button switch 20 and maintenance door 22 integrated into it. That is, for example, the front opening of the display frame 28s can be made smaller than the outer periphery of the built-in transmitter body 12b.

In this way, the disaster prevention equipment storage box 10 of this embodiment has a position indicator light 14 with an indicator frame 28s formed around the entire circumference of the cover plate 10a, an acoustic hole area 16a that overlaps the indicator frame 28s, and a push button switch 20 and maintenance door 22 that are separate from the transmitter body 12, all concentrated in one location, making it possible to significantly reduce the size of the disaster prevention equipment storage box 10 compared to the embodiment of FIG. 29.

In addition, the acoustic hole area 16a is arranged so as to overlap the display frame 28s of the position indicator light 14, and the display frame 28s is not restricted in its arrangement by the acoustic hole area 16a, which increases the degree of freedom regarding the shape and arrangement of the display frame 28s. Note that the indicator light side acoustic hole also corresponds to an opening, and multiple cover plate side acoustic holes may be arranged for one opening.

In addition, when the disaster prevention equipment storage box 10 is installed, visibility from the front is maintained by the display surface 15 on the front surface 13a of the display frame 28s provided on the position indicator light 14, and at the same time, visibility from the side is improved by the display surfaces 15 on both the left and right side surfaces 13b of the display frame 28s, improving the visibility of the indicator light as a whole and providing a new design, thereby enhancing the design.

In addition, in an installation environment where the disaster prevention equipment storage box 10 is installed on a wall or the like and can be seen by users from above and/or below, the display surface 15 on the upper surface 13c and lower surface 13d of the display frame 28s on the position indicator light 28 improves visibility from above and below, thereby improving the visibility of the indicator light as a whole.

Furthermore, the display frame 28s arranged around the push button switch 20 separated from the transmitter body 12b makes it easier to clearly recognize the presence of the transmitter push button switch 20, which functions as an operating unit, and the location of the transmitter push button switch 20 is easy to understand, allowing the user to operate the transmitter push button switch 20 without hesitation. The same is true for the maintenance door 22 arranged separately from the transmitter body 12b, so that during inspection, the person in charge can open the maintenance door 22 without hesitation and insert the plug of a portable telephone into the telephone jack to make a call.

The display frame 28s of the position indicator light 14 arranged on the front surface of the cover plate 10a is arranged so as to surround the push button switch 20 and the maintenance door 22 arranged separately from the transmitter main body 12b in a rectangular shape, but is not limited to this. For example, it may be arranged so as to surround the push button switch 20 and the maintenance door 22 in a circular or elliptical shape. Also, for example, similar to the display frame surrounding part of the periphery of the sound hole area shown in Figures 29 and 31, it may be a display frame that surrounds part of the periphery of the exposed part of the transmitter in a gate shape or the like. Also, for example, as shown in Figure 35, the display frame 28s may be divided and arranged, or an appropriate shape and arrangement may be selected, such as providing the display frame at the four corners when viewed from the front of the storage case.

As another structure of the acoustic hole area 16a with the acoustic hole 16 in the display frame 28s of the position indicator light 14, an opening that serves as the acoustic hole area 16a may be formed in the display frame 28s, and the acoustic hole 16 may be formed in the portion of the front surface 13a of the cover plate 10a that is located within this opening.

In addition, in this embodiment, the joints between the front surface 13a and the side surface 13b of the cover plate 10a are rounded as shown in the plan view of FIG. 34(C), but are not limited to this and may be C-shaped (chamfered), for example, and the display surface 15 of the side surface 13b of the cover plate 10a may be formed to conform to these shapes. This also applies to the joints between the front surface 13a of the cover plate 10a and the upper surface 13c and the lower surface 13d.

[Embodiment of disaster prevention equipment storage box with sound hole provided on the side of the storage case: 7th invention]
Fig. 36 shows an embodiment of a disaster prevention equipment storage box with a sound hole provided on the side of the storage case, Fig. 36(A) shows the front and Fig. 36(B) shows the side. The disaster prevention equipment storage box 10 is usually installed with the arrow shown in Fig. 36(A) facing upward. In this embodiment, as in the embodiment of Figure 34, a push button switch 20 with a protective plate 18 separated from the transmitter main body and a maintenance door 22 are arranged on the front of the cover plate 10a, and display frames 28t for the position indicator lights 14 are arranged separately on both the left and right sides of the front of the cover plate 10a, so as to sandwich the transmitter arrangement area 12c (the area when the entire arrangement area of the transmitter including the transmitter main body built into the storage case is viewed from the front) in which the push button switch 20 and the maintenance door 22 are arranged, and an acoustic hole area 16a with a plurality of acoustic holes 16 is arranged along the inside of this display frame 28t (the side where the push button switch 20 and the maintenance door 22 are arranged). In addition, the display frame 28t also has display surfaces on both the left and right side surfaces of the cover plate 10a, and the acoustic hole area 16a with a plurality of acoustic holes 16 is arranged in the main body 10b along this display frame 28t. Here, the disaster prevention equipment housing box 10 of this embodiment has an arrangement overlapping portion 90 in the vertical direction where the arrangements of the sound hole area 16a, the transmitter arrangement area 12c, and the indicator light 14 overlap.

In addition, an acoustic hole area 16a is also arranged on the side of the cover plate 10a along the display frame 28t.

By arranging the acoustic hole area 16a, which has the acoustic hole 16, on the side of the storage case in this manner, the space in front of the storage case is reduced, making it possible to further miniaturize the disaster prevention equipment storage box 10.

In addition, the acoustic hole area 16a, the transmitter placement area 12c, and the display frame 28t of the position indicator light 14 are arranged so that their placement positions at least partially overlap in the up-down direction (vertical direction) when installed, which alleviates constraints such as the space required to place the acoustic hole 16, the transmitter area 12c, and the position indicator light 14, and improves design freedom.

As shown in FIG. 36(C), the display surface of the indicator light 14 can also be provided on the top surface of the storage case of the disaster prevention equipment storage box 10, and the same can be done on the bottom surface.

Figure 37 shows another embodiment of a disaster prevention equipment storage box with acoustic holes on the side of the storage case, where an acoustic hole area 16a with multiple acoustic holes 16 (cover plate side acoustic holes and indicator light side acoustic holes) is arranged to overlap display frames 28t arranged separately on both the left and right sides of the front of the cover plate 10a, and similarly, an acoustic hole area 16a with multiple acoustic holes 16 is arranged to overlap display frames 28t arranged on both the left and right sides of the cover plate 10a, and in this case too, there is an overlapping arrangement portion 90 as in the embodiment of Figure 36.

Here too, as shown in FIG. 37(C), a display surface for the indicator light 14 can be provided on the top surface of the storage case of the disaster prevention equipment storage box 10, and the same can be done on the bottom surface.

Figure 38 is an explanatory diagram showing an embodiment of a disaster prevention equipment storage box in which indicator lights are arranged on the left and right sides of the sound hole area and have display surfaces on the front and side, and is characterized by a combination of Figures 36 and 37.

In addition, although the acoustic holes are provided on the side of the storage case in Figs. 36 to 38, they may also be provided on the top and bottom surfaces of the storage case. Also, in Figs. 36 to 38, the acoustic holes may not be provided on the front surface of the storage case, but may be provided on the side or top and bottom surfaces of the storage case.

Furthermore, the front display width and side display width of the display frame 28t arranged separately on both the left and right sides of the storage case can be any size relationship, as in the embodiment of FIG. 33.

It should be noted that the disaster prevention equipment storage boxes in Figures 35 to 38 may be installed upside down. Not limited to this, for example, the disaster prevention equipment storage box 10 in Figures 38 to 38 may be installed sideways, in which case the left-right (horizontal) direction in each figure becomes the up-down (vertical) direction in the installed state, and the overlapping portion 90 is formed along the left-right (horizontal) direction in the installed state. Needless to say, when installed sideways, the display surfaces of the top and bottom of the illustrated storage case become the display surfaces of the left and right sides in the installed state, and the display surfaces of the left and right sides of the illustrated storage case become the display surfaces of the top and bottom in the installed state.

Furthermore, the embodiments of the disaster prevention device in which the acoustic hole area, the transmitter arrangement area, and the indicator light in Figures 36 to 38 are arranged so that their arrangement positions at least partially overlap when installed also include the embodiments of the disaster prevention device shown in Figures 11, 13, 18, 34, and 35.

[Modifications of the present invention]
29 to 38, the display surface on the side of the display frame may extend to the main body of the storage case. Also, the display frame may be separated into a display frame having a display surface on the front surface of the storage case and a display frame having a display surface on the side surface.

In the embodiments of Figures 29 to 38, the display surfaces on the left and right sides may be provided only on one side where improved visibility from the side is required. The same applies to the display surfaces on the top and bottom sides.

The storage case in each embodiment may be partially embedded in the wall, and in the embodiments of Figs. 29 to 34, at least a portion of the display surface on the side of the storage case may be exposed from the wall. For example, as explained in the embodiment of Fig. 29, a cover plate with a display frame may be exposed from the wall, and the main body may be embedded in the wall.

The configuration in which the position indicator light and the sound hole area are concentrated in one location in the above embodiment can be applied to a configuration in which the display unit and sound output unit provided in the fire control device are concentrated in one location.

In addition, the above embodiment of the disaster prevention equipment storage box is an example of a case in which the sound hole, the position indicator light located in one place, and the transmitter are arranged vertically, but they may also be arranged horizontally as long as it is in line with the purpose of the present invention.

In the above embodiment, a light-diffusing translucent material is used for the display frame of the position indicator, but an appropriate light-guiding material may also be used. As an example, a light-guiding material may be used in which reflective dots are printed on the back surface of an acrylic light-guiding plate, and light incident from the edge of the light-guiding plate is guided to the entire surface of the acrylic using total reflection from the acrylic. When the light hits the reflective dots, it changes course, and the light that emerges from the front surface of the acrylic at an angle smaller than the angle of total reflection is used to make the entire surface of the light-guiding plate glow uniformly in red. Other known illumination, light-guiding, light-transmitting, and light-diffusing methods may also be applied.

The present invention can also be applied to disaster prevention devices other than equipment housing boxes and fire hydrant devices.

In addition to being a position indicator light, the indicator light may also be an indicator light that indicates an abnormality such as a fire, or any other indicator light.

The present invention can also be applied to disaster prevention devices that do not have a transmitter if the indicator light and sound hole can be arranged together.

Furthermore, the present invention is not limited to the above-described embodiments, and includes appropriate modifications that do not impair the objects and advantages thereof. For example, the above-described embodiments may be combined as appropriate, or other modifications may be applied.

In addition, in the above embodiment, the entire display surface of the display frame of the indicator light is used as the display area (light-emitting area), but only a part of the display surface may be used as the display area.

Furthermore, the present invention is not limited to the shapes and numerical values shown in the above embodiments.
