Description

[Technical Field]

[0001] The present invention relates to disaster prevention devices such as disaster prevention equipment storage boxes and fire hydrant devices that are equipped with a transmitter, an indicator light, and a sound hole and are operated in the event of a fire or the like to notify of the occurrence of an abnormality. [Background technology]

[0002] Conventionally, a disaster prevention equipment storage box is provided with a transmitter and an indicator light (in this case, a position indicator light), and further provided with an acoustic hole corresponding to a built-in bell or buzzer.

[0003] The location indicator light is a red indicator light that stays lit to indicate the location of the disaster prevention equipment storage box, allowing people in the vicinity to locate the transmitter in the event of an emergency. The transmitter turns on the push button switch by pressing 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 the 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 then sounds the bell or buzzer on the disaster prevention equipment storage box to sound a fire alarm.

[0004] Conventional location indicators on disaster prevention equipment storage boxes have a red indicator cover that protrudes a few centimeters forward from the panel surface to improve visibility from the side, but in recent years flat-type location indicators using flat light-emitting elements with multiple LEDs distributed across them have become popular.Flat-type location indicators are also placed around the transmitter to ensure visibility from the side, while limiting their forward protrusion to prevent damage by preventing objects from hitting them, and also improving design.

[0005] Furthermore, a fire hydrant device is also known as a disaster prevention device equipped with a transmitter, a position indicator light, and an acoustic hole. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Publication No. 9-102085 [Patent Document 2] Design Registration No. 1005289 [Patent Document 3] Japanese Patent Application Publication No. 2018-022540 [Patent Document 4] Design Registration No. 1493279 [Patent Document 5] Design Registration No. 1493280 [Patent Document 6] Japanese Patent Application Laid-Open No. 2016-059647 [Patent Document 7] Japanese Patent Application Publication No. 10-124771 [Patent Document 8] Japanese Utility Model Application No. 04-016527 (Japanese Utility Model Application Laid-Open No. 05-066794) [Patent Document 9] Japanese Patent Application Laid-Open No. 2001-262955 [Patent Document 10] Design Registration No. 11460558 Summary of the Invention [Problem to be solved by the invention]

[0007] However, in disaster prevention devices equipped with such conventional flat-type position indicator lights, the display frame of the position indicator light is, for example, a ring-shaped display frame that surrounds the outer periphery of the transmitter, but since the display area is relatively small, visibility may not be sufficient depending on the installation location.

[0008] An object of the present invention is to provide a disaster prevention device that improves the visibility of an indicator light. [Means for solving the problem]

[0009] (Full-screen display frame) The present invention is a disaster prevention device equipped with a transmitter, a sound hole, and a position indicator light on the front of a housing, The position indicator light is characterized by being formed so that it is approximately flat on almost the entire surface outside the area where the transmitter and acoustic hole are located, and protrudes forward, and is equipped with a display frame arranged on the front of the housing so that it emits light that can be seen from the front and sides.

[0010] (Display frame that constitutes the light guide plate) The display frame constitutes a light guide plate having a reflective surface on the rear side, and light is incident on the side edge of the light guide plate, causing the entire surface of the light guide plate to emit light uniformly.

[0011] (Display frame on the left and right when installed) The position indicator light may be formed so as to be substantially flat in the left-right direction and protrude forward when the transmitter and sound hole are installed in the arrangement area. [Effects of the Invention]

[0012] (Effect of the surrounding frame) The present invention is a disaster prevention device in which the display frame of the position indicator light is formed in a frame-like, ladder-like, or oval ring shape to surround the transmitter and sound hole, thereby ensuring a sufficiently large display area that effectively utilizes the free space on the panel surface where the transmitter and sound hole are located, thereby improving visibility.

[0013] (Effect of side-by-side display frames) Furthermore, the display frame of the position indicator light is formed so as to sandwich the transmitter and the sound hole in parallel, ensuring a sufficient display area and improving visibility, especially from the side.

[0014] Furthermore, by making the longitudinal length of the position indicator light approximately the same as the length of the arrangement area of ​​the transmitter and acoustic hole in the direction of alignment, the dimension in the direction of alignment can be made smaller than, for example, when the position indicator light, acoustic hole, and transmitter are arranged in a line.

[0015] (Effect of full-screen display frame) In addition, the display frame of the position indicator light is formed so as to fill almost the entire surface except for the area where the transmitter and acoustic hole are located, so the entire surface except for the area where the transmitter and acoustic hole are located becomes the display area, ensuring a larger display area and improving visibility.Furthermore, the large display area also makes it possible to use it as auxiliary lighting at the installation location at night, etc. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0017] As an embodiment of the present invention, a disaster prevention equipment storage box equipped with an indicator light for indicating a position, a sound hole for outputting a fire alarm sound, and a transmitter for outputting a fire notification signal by operating a switch will be described as an example.

[0018] Fig. 1 is an explanatory diagram showing a first embodiment of a disaster prevention equipment storage box with a position indicator light using a picture frame as an example of a disaster prevention device of the present invention, and Fig. 2 is an explanatory diagram showing the exploded structure of the disaster prevention equipment storage box. Note that the disaster prevention equipment storage box may also be simply called an equipment storage box.

[0019] [Basic concept of the embodiment] The basic concept of this embodiment is a disaster prevention equipment storage box 10 that functions as a disaster prevention device, in which position indicator lights 14 are provided beyond the positions of the transmitters 12 and sound holes 16. For example, the position indicator lights 14 are arranged using frame display frames 28a that surround the outside of the transmitters 12 and sound holes 16 provided on the panel surface (mounting surface) of the cover plate 10a of the disaster prevention equipment storage box 10, thereby ensuring a large display area distributed over a wide range of the panel surface and greatly improving visibility. Furthermore, by surrounding the periphery of the transmitters 12 and sound holes 16 with position indicator lights 14, a new design feature can be obtained, and as a result, the design can be improved.

[0020] Furthermore, the position indicator light 14 has a substantially flat display frame 28a, for example, that conforms to the panel surface of the disaster prevention equipment storage box 10, the display frame 28a being a diffuse light-transmitting member, and an LED 32 that functions as a light source for illuminating the diffuse light-transmitting member being provided behind the display frame 28a, so that the display unit of the position indicator light 14 becomes a substantially flat display frame that conforms to the panel surface of the disaster prevention equipment storage box 10, making it possible to easily form a display pattern with a large display area that improves visibility from the front and sides. This will be described in detail below.

[0021] [First embodiment of disaster prevention equipment storage box] (Outline of disaster prevention equipment storage box) As shown in Figure 1, in the disaster prevention equipment storage box 10 of the first embodiment, a transmitter 12 is arranged on the underside of the exposed surface (arrangement surface) of the cover plate 10a that is exposed when installed on a wall surface or the like, an acoustic hole 16 is arranged above that, and a position indicator light 14 using a frame display frame 28a is arranged to surround the transmitter 12 and the acoustic hole arrangement area 16a.

[0022] The opening shape, size, number and arrangement of each acoustic hole 16 are appropriately selected and adjusted taking into consideration sound output performance, diffusion performance, design, etc.

[0023] The transmitter 12 has a protective plate 18 made of a transparent acrylic plate or the like at its center for turning on a built-in push button switch 20, and a maintenance door 22 with a telephone jack inside.

[0024] 1 may be separated into upper and lower frame display frames 28a-1 and 28a-2 shown in Fig. 2(A) or left and right frame display frames 28a-1 and 28a-2 shown in Fig. 2(B). In other words, the position indicator light 14 does not need to completely surround the transmitter 12 and the sound hole 16, as long as it roughly surrounds them.

[0025] As shown in Figure 3, the disaster prevention equipment storage box 10 is composed of a cover plate 10a and a box-shaped main body 10b. An acoustic device 24 such as a buzzer or bell is placed in a position opposite to the position indicator light 14 attached to the cover plate 10a within the main body 10b behind the light. When the acoustic device 24 is sounded by a local acoustic signal from the receiver, the resulting fire alarm sound is output from the acoustic hole 16 shown in Figure 1.

[0026] (Structure of position indicator light) 4A and 4B are cross-sectional views showing the internal structure of the acoustic hole and the position indicator light in FIG. 1, with FIG. 4A showing the AA cross section in FIG. 1 and FIG. 4B showing the BB cross section in FIG.

[0027] As shown in FIG. 4(A), an acoustic device 24 is disposed in the main body 10b behind the acoustic hole 16 formed in the cover plate 10a, and sound from the acoustic device 24 is output to the outside through the acoustic hole 16.

[0028] 3(B), the position indicator light 14 has a frame 28a arranged on the panel surface of the cover plate 10a, and the cover plate 10a on which the frame 28a is arranged has a plurality of light-transmitting holes 26. A circuit board 34 is arranged inside the cover plate 10a, and an LED 32 functioning as a light source is arranged at a position on the circuit board 34 opposite the light-transmitting holes 26.

[0029] The frame 28a uses a diffuse translucent material that emits red light. The diffuse translucent material is a material that receives light from the point light source, the LED 32, and converts it into surface light. Light from the backlighting of the LED 32 arranged on the circuit board 34 is incident on the frame 28a that uses the diffuse translucent material, causing the entire surface of the position indicator light 14 to emit a substantially uniform red light.

[0030] In this way, in the first embodiment, the position indicator light 14 using the frame display frame 28a is arranged to surround the transmitter 12 and the acoustic hole 16, thereby ensuring a large display area over a wide area of ​​the panel surface and greatly improving visibility from the front and sides.Furthermore, by surrounding the transmitter 12 and the acoustic hole 16 with the position indicator light 14 using the frame display frame 28a, a clear outline is given, resulting in a new design and improving the design.

[0031] 1 may be an oval ring-shaped frame 28a-3 as a whole, as shown in Fig. 2(C), or may be separated into upper and lower or left and right sections, as in the examples of Fig. 2(A) and (B). By using an oval ring-shaped frame 28a-3 in this way, a sense of unity in design can be achieved in line with the round transmitter 12.

[0032] For example, the upper part of the picture frame display frame may be rectangular as shown in FIG. 1, and the lower part may be circular (semicircular) as shown in FIG. 2(C).

[0033] [Second embodiment of disaster prevention equipment storage device] FIG. 5 is an explanatory diagram showing a second embodiment of a disaster prevention equipment storage box in which position indicator lights using a picture frame are arranged along the outer edge of the cover plate.

[0034] As shown in FIG. 5, in this embodiment, a position indicator light 14 using a picture frame 28b is arranged so as to surround the transmitter 12 and the sound hole 16 arranged inside along the outer periphery of the cover plate 10a.

[0035] The frame 28b of the position indicator light 14 is arranged with a predetermined width along the outer periphery of the cover plate 10a, thereby ensuring a wider distribution and display area than the frame 28a shown in Fig. 1, thereby ensuring even higher visibility. The other configurations and functions are the same as those of the first embodiment shown in Fig. 1, so a description thereof will be omitted.

[0036] [Third embodiment of disaster prevention equipment storage device] FIG. 6 is an explanatory diagram showing a third embodiment of a disaster prevention equipment storage box in which position indicator lights using ladder-shaped display frames are arranged along the outer edge of the cover plate.

[0037] As shown in Fig. 6, in this embodiment, position indicator lights 14 using ladder-shaped display frames 28c are arranged so as to individually surround the transmitters 12 and acoustic holes 16 that are arranged inside along the outer periphery of the cover plate 10a. The ladder-shaped display frame 28c has a shape in which a display frame is added horizontally between the transmitters 12 and acoustic holes 16 of the picture-frame display frame 28b shown in Fig. 4, which increases the distribution and display area of ​​the display frames and further improves visibility.

[0038] Furthermore, the ladder-shaped display frame 28c provides individual contours around the transmitter 12 and the acoustic hole 16, enhancing the design. The rest of the configuration and functions are the same as those of the first embodiment shown in Figure 1, so a description thereof will be omitted.

[0039] [Fourth embodiment of disaster prevention equipment storage device] FIG. 7 is an explanatory diagram showing a fourth embodiment of a disaster prevention equipment storage box in which a transmitter and a position indicator light are arranged with display frames arranged on either side of a sound hole.

[0040] As shown in Figure 7, in this embodiment, the position indicator light 14 is formed by arranging a pair of vertical bar-shaped straight display frames 28d in parallel on both sides of the transmitter 12 and the acoustic hole 16, which are arranged side by side above and below on the panel surface of the cover plate 10a, so as to sandwich the transmitter 12 and the acoustic hole 16 from the left and right.

[0041] The disaster prevention equipment storage box 10 installed on a wall is primarily visible from the side, and in response to this, the position indicator light 14 of this embodiment has a pair of straight display frames 28d arranged vertically, sandwiching the transmitter 12 and sound hole 16 on either side, ensuring the distribution and display area of ​​the display frames when viewed from the side and front, and even though no bar-shaped display frame portion is arranged horizontally (left and right), the visibility that is originally required is not impaired, and visibility from a distance can be ensured by simply arranging the display frames.

[0042] Furthermore, by making the longitudinal length (vertical direction in Figure 7) of the position indicator light 14 approximately the same as the length of the arrangement area of ​​the transmitter 12 and the acoustic hole 16 in the arrangement direction, the dimension in the arrangement direction can be made smaller than when, for example, the position indicator light, acoustic hole, and transmitter are arranged in a line.

[0043] The other configurations and functions are the same as those of the first embodiment shown in FIG. 1, and therefore the description thereof will be omitted.

[0044] In this embodiment, a pair of straight display frames 28d are arranged vertically to sandwich the transmitter 12 and the acoustic hole 16 from the left and right, but a pair of horizontal bar-shaped straight display frames may also be arranged horizontally to sandwich the transmitter 12 and the acoustic hole 16 from above and below. Furthermore, in addition to the pair of straight display frames arranged above and below sandwiching the transmitter 12 and the acoustic hole 16, a three-line configuration may also be used, in which a straight display frame is arranged between the transmitter 12 and the acoustic hole 16.

[0045] [Fourth embodiment of disaster prevention equipment storage device] FIG. 8 is an explanatory diagram showing a fifth embodiment of a disaster prevention equipment housing box in which position indicator lights are arranged so that the arrangement surface area (empty area) of the cover plate 10a, excluding the arrangement area of ​​the transmitter and sound hole, is generally filled with an indicator frame.

[0046] As shown in Figure 8, in this embodiment, the position indicator light 14 is formed by arranging a full-surface display frame 28e so as to fill almost the entire empty space except for the area where the transmitter 12 and acoustic hole 16 are arranged side by side on the panel surface of the cover plate 10a.

[0047] That is, the full-surface display frame 28e of the position indicator light 14 has the same approximately planar shape as the cover plate 10a, and has an opening 30a for a transmitter and an opening 30b for an acoustic hole formed therein, and LEDs are arranged in a grid pattern through light-transmitting holes on the back side of the cover plate 10a on which the full-surface display frame 28e is arranged.

[0048] The position indicator light 14 using the full-face display frame 28e ensures a large display area as the position indicator light 14 for the disaster prevention equipment storage box 10, ensuring high visibility from the front and sides. In addition, because the display area of ​​the position indicator light 14 is large, it can also function as auxiliary lighting at night in the hallway or the like where the disaster prevention equipment storage box 10 is installed.

[0049] Furthermore, a new design element is created and, as a result, the design is enhanced by providing an outline around the transmitter 12 and the sound hole 16 by the full-face display frame 28e of the position indicator light 14. The other configurations and functions are the same as those of the first embodiment shown in Fig. 1, so a description thereof will be omitted.

[0050] In addition, multiple acoustic hole openings can be formed at positions corresponding to multiple acoustic holes, i.e., the position indicator light (full-surface display frame) can also cover the acoustic hole arrangement area, and multiple indicator light side acoustic holes can be provided at positions corresponding to the acoustic hole 16 of the position indicator light 14, thereby obtaining an even larger display area.

[0051] [Fire hydrant equipment] FIG. 9 is an explanatory diagram showing an embodiment of a fire hydrant device in which a position indicator light is arranged around a transmitter and a sound hole.

[0052] 9, the fire hydrant device 50 of this embodiment has a hydrant door 54 that can be opened and closed freely on the front of a metal storage box 52, a reporting panel 56 above the hydrant door 54, a transmitter 12 and sound hole 16 arranged on a cover plate 10a of the reporting panel 56, and a position indicator light 14 using a picture frame 28f that surrounds the transmitter 12 and sound hole 16. A hose with a nozzle is stored inside the hydrant door 54.

[0053] The position indicator light 14 is basically the same as the position indicator light 14 provided in the disaster prevention equipment storage box 10 in Figure 5, and is provided with a horizontally long rectangular frame display frame 28f, which surrounds the transmitter 12 and sound hole 16 arranged side by side to form the position indicator light 14.

[0054] In this embodiment as well, the position indicator light 14 having the frame display frame 28f surrounding the periphery of the transmitter 12 and the sound hole 16 is installed, thereby improving the visibility of the fire hydrant device 50 when viewed from a distance, including from the front and side. Furthermore, by surrounding the transmitter 12 and the sound hole 16 with the frame display frame 28f of the position indicator light 14, a clear outline is given, thereby enhancing the design.

[0055] The notification panel 56 of FIG. 9 may be provided with a position indicator light 14 similar to that provided on the disaster prevention equipment storage box 10 of FIG. 1, FIG. 2, FIG. 6, FIG. 7 or FIG.

[0056] [Modifications of the present invention] In the above-described embodiment of the disaster prevention equipment storage box, the transmitter and the sound hole are arranged vertically, but they may also be arranged horizontally. Note that the outer shape of the display frame shown in each embodiment may be changed as appropriate.

[0057] The present invention can also be applied to disaster prevention devices other than equipment housing boxes and fire hydrant devices. In addition to position indicator lights, the present invention can also be applied to indicator lights that indicate abnormalities such as fires, or other indicator lights.

[0058] 1, 2, 5, 6, 7, and 9, the acoustic hole arrangement area may overlap with the display frame of the position indicator light, as described in the embodiment of Fig. 8. In this case, for example, an indicator light acoustic hole may be provided at a position corresponding to the acoustic hole of the display frame of the position indicator light.

[0059] Furthermore, in the above embodiment, a light-diffusing and translucent material is used for the display frame of the position indicator light, but an appropriate light-guiding material may also be used. As an example, the light-guiding material may be an acrylic light-guiding plate with reflective dots printed on the back surface. 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 total reflection angle is used to make the entire surface of the light-guiding plate glow uniformly in red. Other known lighting, light-guiding, light-transmitting, and light-diffusing methods may also be used.

[0060] In addition, in the above-described embodiment, the frame-shaped or ladder-shaped display frame has a flat display surface that conforms to the panel surface, but it may also be formed to have an inclined or curved display surface with the inner periphery slightly protruding outward from the outer periphery, thereby improving visibility from the diagonal side.

[0061] Furthermore, the present invention is not limited to the above-described embodiments, but includes appropriate modifications that do not impair the objects and advantages thereof, and is not limited by the shapes and numerical values ​​shown in the above-described embodiments.
