Description

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

Conventionally, position indicator lights installed on disaster prevention equipment storage boxes are red indicator lights with indicator covers that protrude forward from the panel surface by several centimeters to improve visibility from the side. In recent years, however, flat-type position indicator lights that do not protrude forward to prevent damage due to being hit by objects and that also have a more aesthetically pleasing appearance have become popular.

Furthermore, fire hydrant devices, for example, are also known as disaster prevention devices equipped with position indicator lights, sound holes, and transmitters.

Japanese Patent Application Laid-Open No. 9-102085 Design Registration No. 1005289 Design Registration No. 1138299 JP 2016-059647 A JP 2015-018445 A JP 2007-229108 A

However, in disaster prevention devices with flat position indicator lights, there were cases where visibility from the side was insufficient. Or, in order to ensure visibility from the side, there were limitations to reducing the amount of protrusion of the indicator light and making it thinner. This also led to the problem of limited freedom in improving the design of the position indicator light and disaster prevention device.

The objective of the present invention is to provide a disaster prevention device that ensures visibility from the front and sides through the indicator lights, while reducing the dimensions in the direction in which the indicator lights and transmitters are arranged, improving the design, and further improving ease of use.

(Disaster prevention device 1)
The present invention is a disaster prevention device in which two functional units having predetermined functions are arranged side by side on the front surface of a storage case,
An indicator light having a display surface extending from one side surface to the other side surface through the front surface of the storage case ,
The indicator lamp is characterized in that, in the arrangement direction of the two functional units, the side dimension of the display surface in the arrangement direction is larger than the dimension of the front center part of the display surface in the arrangement direction .

(Continuous display surface)
The indicator light is characterized by having a continuous indication surface extending from one side surface to the other side surface in the arrangement direction of the two functional units.

(2 functional units)
At least one of the two functional units is an acoustic hole area or a transmitter.

(Disaster Prevention Device 2)
A disaster prevention device in which a sound hole area having a plurality of sound holes and a transmitter are arranged side by side on a front surface of a storage case,
An indicator light having a display surface extending from one side surface to the other side surface through the front surface of the storage case,
The indicator light is characterized in that the indication surface overlaps part or all of the acoustic hole area, and the overlapping portion has an opening at a position corresponding to the acoustic hole.

(Dimensional relationship between acoustic hole area and transmitter arrangement direction)
The indicator lamp is formed such that the dimension of the side of the display surface in the arrangement direction is larger than the dimension of the front center of the display surface in the arrangement direction in the direction of arrangement of the sound hole areas and the transmitters.

(Basic Effects)
The present invention is a disaster prevention device in which an acoustic hole area and a transmitter are arranged side by side on the front of a storage case, and includes an indicator light having a display surface from one side to the other side via the front of the storage case, and the indicator light is formed so that the side dimension of the display surface is larger than the front center dimension of the display surface in the arrangement direction of the acoustic hole area and the transmitter, so that high visibility from the side is ensured while reducing the dimensions of the arrangement direction of the acoustic hole area, indicator light, and transmitter, and the visibility of the indicator light as a whole can be improved. Also, by making the side dimension of the display surface of the indicator light larger than the front center dimension, a new design can be obtained and the design can be improved.

(Effect of the dimensional relationship between the sound hole, transmitter and indicator light display surface)
In addition, the front central alignment dimension of the display surface of the indicator light is made smaller than the alignment dimension of the acoustic hole area and the transmitter, and the side alignment dimension of the display surface is made approximately equal to or greater than the alignment dimension of the acoustic hole area and the transmitter.Therefore, when the acoustic hole area, indicator light and transmitter are arranged in a line, a balanced arrangement is achieved in which the alignment dimensions are reduced, and since the side alignment dimension of the display surface is approximately equal to or greater than the alignment dimension of the acoustic hole area and the transmitter, high visibility from the side is ensured without compromising visibility from the front, and the design can also be improved.

(Effect of positioning of indicator lights)
In addition, the indicator light is located between the acoustic hole area and the transmitter, in a position that sandwiches the acoustic hole area and the transmitter on both sides, or in a position that surrounds part of the transmitter.This allows the empty space between the acoustic hole and the transmitter located on the front of the storage case to be utilized to create a variety of display surface shapes and arrangements.In addition to ensuring visibility of the indicator light from the front and sides, there is a high degree of freedom in the arrangement and shape of the display surface, improving design.

In addition, if the indicator light is provided in a position that surrounds part of the transmitter, the indicator light will point out the transmitter, preventing the user from getting confused when operating it, improving the operability of the transmitter.

(Effect of flush display surface of indicator lamp)
In addition, the display surface on the front of the indicator light is approximately flush with the front surface of the storage case, and the display surface on the side of the indicator light is approximately flush with the side surface of the storage case.Therefore, 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, which prevents the indicator light from protruding from the surface of the storage case and makes it easy to form various display patterns that improve visibility from the front and sides.

(Effect of arranging transmitters flush)
In addition, since the transmitter is positioned so that it is approximately flush with the front surface of the storage case, the front surface of the transmitter is approximately flat and conforms to the front surface of the storage case, which reduces the transmitter's protrusion from the surface of the storage case, and is expected to improve the design, etc.

Figure 1 is an explanatory diagram showing a first embodiment of a disaster prevention device storage box as an example of the disaster prevention device of the present invention, in which a position indicator light with a roughly H-shaped display surface is arranged from the front to the side of the panel of the storage case.

[Basic Concept of the Embodiment]
The basic concept of this embodiment is a disaster prevention equipment storage box 10, which is characterized by providing a position indicator light 14 with an approximately H-shaped display frame 28a having a display surface 15 on the front 13a and side 13b of the storage case consisting of a cover plate 10a (panel) and a main body 10b. As shown in Figure 1 (A) , the approximately H-shaped display frame 28a has a side arrangement direction dimension L2 that is larger than the front center arrangement direction dimension L1 in the arrangement direction of the transmitter 12 and the acoustic hole 16 (L1 < L2). By reducing the arrangement direction dimensions of the acoustic hole 16, position indicator light 14, and transmitter 12 while increasing the side arrangement direction dimension L2, high visibility from the side is ensured, and the visibility of the indicator light as a whole can be improved.

In addition, the display frame 28a of the position indicator light 14 is arranged from the front to the side, and the display frame 28a is made approximately H-shaped, which provides a new design and improves the design.

[First embodiment of disaster prevention equipment storage box]
(Outline of disaster prevention equipment storage box)
1A and 1B, the storage case of the disaster prevention equipment storage box 10 of the first embodiment is composed of a cover plate 10a and a main body 10b, and the transmitter 12 is disposed on the underside of the exposed surface (front surface 13a) of the cover plate 10a that is exposed when the box is installed on a wall or the like, and an acoustic hole area 16a with an acoustic hole 16 is disposed above the cover plate 10a. In general, the disaster prevention equipment storage box 10 is installed on a wall or the like with the acoustic hole area 16a side facing the ceiling and the transmitter 12 side facing the floor, ... transmitter 12, the acoustic hole area 16a side facing the transmitter 12, the acoustic hole area 16a side facing the transmitter 12, the acoustic hole area 16a side facing the transmitter 12, the acoustic hole area 16a side facing the transmitter 12, the acoustic hole area 16a side facing the transmitter 12, the acoustic hole area 16a side facing the transmitter

The opening shape, size, number and arrangement of each acoustic hole 16 are appropriately selected and adjusted taking into consideration the sound output performance, diffusion performance, design, etc.

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 position indicator light 14 has a roughly H-shaped display frame 28a that extends from the front surface 13a to the side surface 13b between the transmitter 12 and the sound hole 16 of the cover plate 10a, so that the position indicator light 14 has a display surface 15 on the front surface 13a and the side surface 13b of the storage case of the disaster prevention equipment storage box 10.

The display surface of the display frame 28a of the position indicator light 14 has a larger dimension L2 on both the left and right sides in the arrangement direction of the acoustic hole area 16a, which is the arrangement area of the transmitter 12 and the acoustic hole 16, compared to the arrangement direction dimension L1 at the center of the front (L1 < L2). Here, by making L1 smaller, the dimensions in the arrangement direction of the acoustic hole area 16a, the position indicator light 14, and the transmitter 12 can be reduced compared to conventional methods.

For example, the front center dimension L1 of the display frame 28a of the position indicator light 14 is set to be smaller than the dimension of each of the acoustic hole area 16a and the transmitter 12 alone (in the case of FIG. 1(A), the diameter of the outer edge of the acoustic hole area 16a (shown with two-dot chain line)), for example, about 1/2 or less, and the side dimension L2 of the display frame 28a is set to be approximately the same as or larger than the dimension of the acoustic hole area 16a and the transmitter 12.

Due to the relationship between the front center and sides of the display frame 28a and the dimensions of the acoustic hole area 16a and the transmitter 12 in the line-up direction, when the acoustic hole 16, the position indicator light 14, and the transmitter 12 are arranged in a line-up direction, a balanced arrangement is achieved that reduces the dimensions in the line-up direction. In addition, since the side line-up direction dimension L2 of the display frame 28a is approximately the same as the line-up dimension of the acoustic hole area 16a and the transmitter 12, high visibility from the side is ensured without compromising visibility from the front, and the design can also be improved.

Furthermore, the left and right sides of the display frame 28a of the indicator light 14 are also provided with a display surface 15 on the side of the storage case, further improving visibility from the side.

In this embodiment, the transmitter 12 is incorporated into a recess 17 formed by stepping off the front surface 13a of the cover plate 10a of the disaster prevention equipment storage box 10, and the front surface of the transmitter 12 is arranged so that it is approximately flush with the front surface 13a of the cover plate 10a. In this way, the front surface of the transmitter 12 is approximately flat along the front surface 13a of the cover plate 10a of the disaster prevention equipment storage box 10, which makes it possible to reduce the protrusion of the transmitter 12 from the front surface 13, and is expected to improve the design, etc.

(Structure of Position Indicator Light)
Fig. 2 is an explanatory diagram showing the exploded structure of the disaster prevention equipment storage box of Fig. 1. As shown in Fig. 2, 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 disposed in a position facing the position indicator light 14 attached to the cover plate 10a in the main body 10b behind the position indicator light 14. 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 Fig. 1(A).

A recess 17 is formed at the position where the transmitter is placed on the front of the cover plate 10a, and the transmitter 12 is incorporated into the recess 17. The front top 12a of the transmitter 12 does not protrude from the front surface 13 of the cover plate 10a, but is approximately flush with the surface.

Figure 3 is a cross-sectional view showing the internal structure of the position indicator light along the X-X cross section of Figure 1 (A). As shown in Figure 3, the position indicator light 14 has an indicator frame 28a that is open at the rear and has a roughly U-shaped cross section when viewed from the front to both sides of the disaster prevention equipment storage box 10 (when viewed from above the disaster prevention equipment storage box 10), and is disposed on the cover plate 10a.

A circuit board 30 is disposed on the rear side of the display frame 28a, and multiple LEDs 32 are disposed on the circuit board 30. The display frame 28a uses a diffuse translucent material that emits red light. The diffuse translucent material is a material that receives light from the light source LEDs 32, diffuses it, and converts it into surface light. The light from the backlighting from the LEDs 32 disposed on the circuit board 30 is incident on the display frame 28a that uses the diffuse translucent material, causing the front and sides of the position indicator light 14 to emit a substantially uniform surface light in red.

The mounting structure of the position indicator light 14 to the cover plate 10a is not limited to that shown in FIG. 3, and any suitable mounting structure can be used.

In this way, in the first embodiment, the display frame 28a of the position indicator light 14 has a smaller front center dimension L1 in the direction of the arrangement of the transmitter 12 and the acoustic hole area 16a, and in addition, the side dimension L2 is larger than L1, so that the dimensions in the direction of the arrangement of the acoustic hole 16, the position indicator light 14, and the transmitter 12 can be reduced.

In addition, the display surface on the front of the display frame 28a provided on the position indicator light 14 ensures high visibility from the front, and at the same time, since the side dimensions of the display frame 28a in the alignment direction are large, the display surfaces on the sides ensure high visibility from the side, improving the visibility of the indicator light as a whole.

In addition, the display surface of the display frame 28a of the position indicator light 14 is arranged from the front surface 13a to the side surface 13b of the disaster prevention equipment storage box 10, further improving visibility from the side, and the approximately H-shaped display frame 28a provides a new design and enhances the design.

[Second embodiment of disaster prevention equipment storage box]
FIG. 4 is an explanatory diagram showing a second embodiment of a disaster prevention equipment storage box in which a display surface of a substantially H-shaped display frame for a position indicator light is provided on the front panel of the storage case between the sound hole area and the transmitter.

As shown in FIG. 4, in this embodiment, a position indicator light 14 having a roughly H-shaped indicator frame 28b is disposed between the transmitter 12 and the sound hole area 16a on the front surface 13 of the cover plate 10a of the disaster prevention equipment storage box 10.

The display frame 28b of the position indicator light 14 is a reduced dimension in a direction perpendicular to the arrangement direction of the approximately H-shaped display frame 28a provided in the first embodiment shown in Figure 1, with the display surface being located only on the front surface 13 of the cover plate 10a.

Similar to the display frame 28a in FIG. 1, the display frame 28b has a side dimension L2 larger than the front center dimension L1 in the arrangement direction of the transmitter 12 and the acoustic hole area 16a (L1<L2). Also, the front center dimension L1 of the display frame 28b is small, for example, about 1/2 or less of the arrangement direction dimension of the acoustic hole area 16a and the transmitter 12, and the side dimension L2 of the display frame 28b is approximately the same as or larger than the arrangement direction dimension of the acoustic hole area 16a and the transmitter 12.

In this embodiment, the position indicator light 14 has an approximately H-shaped display frame 28b provided on the exposed surface (front surface 13a) of the cover plate 10a, which is exposed when the disaster prevention equipment storage box 10 is embedded in a wall or the like, and this allows the dimensions of the acoustic hole area 16a, the position indicator light 14, and the transmitter 12 to be reduced in the arrangement direction, ensuring high visibility from the front when the disaster prevention equipment storage box 10 is embedded in a wall or the like. At the same time, by increasing the side arrangement direction dimension L2 of the display frame 28a, high visibility from the side is ensured, improving the visibility of the indicator light as a whole. Furthermore, the approximately H-shaped display frame 28b provides a new design and can improve the design.

In this embodiment, at least a portion of the H-shaped display frame, for example the left and right sides, protrudes slightly (for example, by a few millimeters) from the exposed surface of the cover plate 10a.

[Third embodiment of disaster prevention equipment storage box]
FIG. 5 is an explanatory diagram showing a third embodiment of a disaster prevention equipment storage box in which a display surface of a roughly drum-shaped display frame for a position indicator light is provided on the front and side of the panel of the storage case between the sound hole area and the transmitter.

As shown in FIG. 5, in this embodiment, a roughly drum-shaped display frame 28c of the position indicator light 14 is disposed between the acoustic hole area 16a and the transmitter 12, and extends continuously from the center of the front to both sides (in a direction perpendicular to the arrangement direction). This display frame 28c has a display surface that extends from the front to the side of the storage case.

The generally drum-shaped display frame 28c of the position indicator light 14 has a side dimension L2 that is larger than the front center dimension L1, and the front center dimension L1 is smaller, for example, about 1/2 or less than the dimension in the direction of the arrangement of the acoustic hole area 16a and the transmitter 12, while the side dimension L2 of the display frame 28a is approximately the same as or larger than the dimension in the direction of the arrangement of the acoustic hole area 16a and the transmitter 12. The rest of the configuration is the same as the embodiment in FIG. 1.

In this third embodiment, the side dimension L2 of the display frame 28c of the position indicator light 14 is larger than the front center dimension L1, which reduces the dimensions of the acoustic hole area 16a, the position indicator light 14, and the transmitter 12 in the arrangement direction.

In addition, the front display surface of the roughly drum-shaped display frame 28c provided on the position indicator light 14 ensures high visibility from the front, while the display surfaces on the left and right sides of the display frame 28c, which have a larger dimension in the alignment direction, ensure high visibility from the side, improving the visibility of the indicator light as a whole.

In addition, the display surface of the display frame 28c of the position indicator light 14 is arranged from the front to both sides of the disaster prevention equipment storage box 10, and the side of the storage case also has a display surface, so visibility from the side is further improved, and the roughly drum-shaped display frame 28c provides a new design and can be improved.

[Fourth embodiment of disaster prevention equipment storage box]
FIG. 6 is an explanatory diagram showing a fourth embodiment of a disaster prevention equipment storage box in which the display surfaces of the display frames of the position indicator lights are provided on the front and side panels of the storage case, sandwiching the sound hole area and the transmitter.

As shown in FIG. 6, in this embodiment, a pair of display frames 28d are arranged separately above and below the acoustic hole area 16a and the transmitter 12, and the display frames 28d arranged separately above and below have a display surface that extends from the front to the side of the storage case.

The display frames 28d arranged above and below have arc-shaped curves on the sides on the acoustic hole area 16a side and the transmitter 12 side, and in the direction of arrangement of the transmitter 12 and acoustic hole 16, the side dimension L2/2 is larger than the front center dimension L1/2, and the front center dimension L1/2 is smaller, for example, about 1/4 or less of the dimension of the acoustic hole area 16a and the transmitter 12, and the side dimension L2/2 of the display frame 28a is approximately 1/2 or more of the dimension of the acoustic hole area 16a and the transmitter 12.

Here, the display frames 28d arranged vertically correspond to the display frame 28c of the third embodiment in FIG. 5 being divided in two in the arrangement direction, with the upper side moved downward and the lower side moved upward, and when the display frames 28d separated vertically are integrated, they will be approximately the same as the display frame 28c in FIG. 5. Based on this, the front center arrangement direction dimension L1/2 and the side arrangement direction dimension L2/2 of the display frames 28d arranged vertically are determined. The rest of the configuration is the same as the embodiment in FIG. 1.

In this fourth embodiment, the display frames 28a arranged above and below the position indicator light 14 have a side dimension L2/2 that is larger than the front center dimension L1/2, which reduces the dimensions of the acoustic hole 16, position indicator light 14, and transmitter 12 in the arrangement direction.

In addition, the display surfaces on the front of the upper and lower display frames 28d provided on the position indicator light 14 ensure high visibility from the front, and at the same time, the display surfaces on the sides of the display frames 28d, which have larger dimensions in the alignment direction, ensure high visibility from the side, improving the visibility of the indicator light as a whole.

In addition, the display frame 28d of the position indicator light 14 is separated into upper and lower halves, and the display surfaces of the upper and lower display frames 28d are arranged from the front of the storage case of the disaster prevention equipment storage box 10 to the left and right sides, which further improves visibility from the side and provides a new design, thereby enhancing the design.

[Fifth embodiment of disaster prevention equipment storage box]
FIG. 7 is an explanatory diagram showing a fifth embodiment of a disaster prevention equipment storage box in which the display surface of a display frame for a position indicator lamp is provided on the front and side panels of the storage case, surrounding the lower side of the transmitter.

As shown in FIG. 7, in this embodiment, a display frame 28e is disposed below the transmitter 12, and the display frame 28e has a display surface that extends from the front to the side of the storage case.

The display frame 28e has an arc shape on the side facing the transmitter 12 that expands continuously from the front center to the left and right sides, and the side dimension L2/2 is larger than the front center dimension L1/2, and the front center dimension L1/2 is small, for example, about 1/4 or less of the dimension in the direction of the acoustic hole area 16a and the transmitter 12, while the side dimension L2/2 of the display frame 28a is approximately 1/2 or more of the dimension in the direction of the acoustic hole area 16a and the transmitter 12.

Here, this embodiment corresponds to removing the upper display frame 28d in the fourth embodiment shown in FIG. 6 and leaving only the lower display frame 28d.

In this way, in the fifth embodiment, the display frame 28e of the position indicator light 14 located below the transmitter 12 is made larger in the side direction dimension L2/2 than in the front center direction dimension L1/2, which further reduces the dimensions of the acoustic hole 16, position indicator light 14, and transmitter 12 in the direction of arrangement.

In addition, the display surface on the front of the display frame 28e of the position indicator light 14 located below the transmitter 12 ensures high visibility from the front, and at the same time, the display surface on the side of the display frame 28e, which has a larger dimension in the arrangement direction, ensures high visibility from the side, improving the visibility of the indicator light as a whole.

In addition, the display frame 28e of the position indicator light 14 is positioned below the transmitter 12, and the display surface of the display frame 28e is positioned from the front to both sides of the disaster prevention equipment storage box 10, further improving visibility from the side and providing a new design element, thereby enhancing the design.

Furthermore, the display frame 28e arranged on the side of the transmitter 12 makes it easier to clearly recognize the presence of the transmitter 12, which functions as an operating unit, making it easier to find the location of the transmitter 12 and enabling the user to operate the transmitter 12 without getting lost.

The display frame 28e of the position indicator light 14 according to this embodiment has a display surface area that is half that of the display frame 28d of the upper and lower position indicator lights 14 according to the fourth embodiment shown in FIG. 6, which are arranged one above the other. However, visibility can be improved by, for example, increasing the light emission of the LED used for backlighting.

[Sixth embodiment of disaster prevention equipment storage box]
FIG. 8 is an explanatory diagram showing a sixth embodiment of a disaster prevention equipment storage box in which a transmitter is surrounded in a gate-like shape and display frames for position indicator lights are provided on the front and side panels of the storage case.

As shown in FIG. 8, in this embodiment, the position indicator light 14 has a display frame 28f arranged to surround the transmitter 12 in a gate shape, and the display frame 28f has a display surface that extends from the front to the side of the storage case.

The generally gate-shaped display frame 28f of the position indicator light 14 has a side dimension L2 that is larger than the front center dimension L1, and the front center dimension L1 is smaller, for example, about 1/2 or less than the dimension in the direction of the acoustic hole area 16a and the transmitter 12, and the side dimension L2 of the display frame 28f may be larger than or about the same as the dimensions in the direction of the acoustic hole area 16a and the transmitter 12 as shown. The rest of the configuration is the same as the embodiment in FIG. 1.

In this sixth embodiment, the side dimension L2 of the gate-shaped indicator frame 28f of the position indicator light 14 arranged around the transmitter 12 is made larger than the front center dimension L1, which reduces the dimensions of the acoustic hole area 16a, the position indicator light 14, and the transmitter 12 in the arrangement direction.

In addition, the display surface on the front of the display frame 28f provided on the position indicator light 14 ensures high visibility from the front, and at the same time, the display surface on the side of the display frame 28d, which has a larger dimension in the alignment direction, ensures high visibility from the side, improving the visibility of the indicator light as a whole.

In addition, the display frame 28f of the position indicator light 14 is roughly gate-shaped, and the display surface of the display frame 28f is arranged from the front to the side of the storage case of the disaster prevention equipment storage box 10, which further improves visibility from the side and provides a new design, thereby enhancing the design.

Furthermore, the roughly gate-shaped display frame 28f arranged around the transmitter 12 side makes it easier to clearly recognize the presence of the transmitter 12, which functions as an operating unit, making it easier to find the location of the transmitter 12 and enabling the user to operate the transmitter 12 without getting lost.

[Modifications of the present invention]
The shape and arrangement of the position indicator having an indication surface on the front surface or on the front surface and side surface of the storage case in the above embodiment is not limited to the above embodiment, and may be any suitable shape and arrangement as required.

In addition, the joint between the front and side of the storage case in this embodiment may be a C-shaped (chamfered) 10c, as shown in the plan view of FIG. 9(A), or an R-shaped 10d, as shown in the plan view of FIG. 9(B), and the display surface of the side of the display frame, on the side of the storage case, may be formed to follow these shapes.

In addition, in the above embodiment, a corresponding recess is provided in the transmitter placement portion of the storage case, and the transmitter is stored in this recess so that the front of the transmitter is approximately flush with the front of the storage case, but this does not prevent the transmitter from being positioned so that its entire surface protrudes slightly from the front of the storage case.

Furthermore, there is no prohibition on the acoustic hole arrangement portion (acoustic hole area) and the display frame or display surface of the indicator light overlapping. In this case, an appropriate opening (indicator light side acoustic hole) may be provided in the overlapping portion at a position of the indicator light corresponding to the acoustic hole.

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 disaster prevention equipment storage 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.

In addition, in each of the above embodiments, the entire exposed portion of the display frame is the display surface, but only a portion of the display frame may be the display surface. In this case, the dimensions of the display frame in each embodiment should be interpreted as the dimensions of the display surface.

In addition, in each embodiment, the display frame (display surface) on the side may extend from the cover plate to the side of the main body.

The present invention can also be applied to disaster prevention devices in which at least one of the acoustic hole (acoustic hole area) and the transmitter shown in the above embodiment is replaced with a functional unit having another function.

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

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