Description

Technical Field

[0001] The present invention relates to a disaster prevention device housing box for a fire alarm device, a fire hydrant device, etc., which is provided with a position indicator lamp and a sound hole, or further provided with a transmitter, and is operated during a fire or the like to notify an abnormal occurrence.

Background Art

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

[0003] The position indicator lamp uses a red indicator lamp and is constantly lit to indicate the position of the disaster prevention device housing box, so that people around can recognize the location of the transmitter in an emergency. The transmitter turns on the push button switch by pushing in a protective plate arranged on the transmitter cover, and transmits a fire alarm signal to the receiver to give an alarm. When the receiver receives a fire alarm signal from the transmitter and outputs a fire alarm, the receiver sends a district sound signal to the disaster prevention device housing box that has transmitted the fire alarm signal, thereby causing the bell or buzzer of the disaster prevention device housing box to sound and output a fire alarm sound.

[0004] By the way, although the conventional disaster prevention device housing box is provided with a transmitter, a position indicator lamp, and a sound hole, in order to reduce the installation space of these and miniaturize the disaster prevention device housing box, a device in which the position indicator lamp and the transmitter are integrated has been proposed. The integration of the position indicator lamp and the transmitter is achieved by arranging a flat light-emitting member in which a plurality of LEDs are distributed around the transmitter to perform surface light emission.

[0005] In addition, a fire hydrant device is also known as a disaster prevention device provided with a transmitter, a position indicator lamp, and a sound hole in this way.

[0007] However, in such a disaster prevention device in which a transmitter and a position indicator lamp are integrated, the transmitter functions as an operation unit, and the position indicator lamp and the sound hole function as a notification unit. However, since the operation unit and the notification unit are not separated, there is a possibility that the operator may be confused.

[0008] In addition, the integration of the position indicator lamp and the transmitter requires the position indicator lamp to be arranged so as to surround the periphery of the transmitter structurally. There is a problem that the shape of the position indicator lamp is restricted to an annular shape, and the degree of freedom for enhancing the designability of the position indicator lamp is low.

[0009] An object of the present invention is to provide a disaster prevention device that can improve operability and designability while reducing the installation space by intensively arranging housing devices and miniaturizing them. [Means for Solving the Problems]

[0017] (Fifth Invention: Concentrated Arrangement of Display Lamp with Display Surface on Front and Side Surfaces of Disaster Prevention Device and Acoustic Hole) Another form of the present invention is a disaster prevention device, in which an indicator lamp and an acoustic hole area are provided in a concentrated manner in a housing case, and the indicator lamp has display surfaces on the front and side surfaces of the housing case.

[0018] (Arrangement of indicator lamp and acoustic hole area) The display surface of the indicator lamp is provided at a position surrounding part or all of the periphery of the acoustic hole area, or at a position sandwiching from above and below and / or left and right.

[0019] (Display surface of indicator lamp provided with acoustic hole) Furthermore, acoustic holes are provided on the front surface of the display frame of the indicator lamp.

[0020] (Overlapping arrangement of indicator lamp area and acoustic hole area) Also, in the first, second, and fifth inventions, the display surface of the indicator lamp and the acoustic hole area are arranged such that at least a part thereof overlaps with each other.

[0021] (Sixth invention: Concentrated arrangement of indicator lamp with display surfaces on the front and side surfaces of the disaster prevention device, transmitter, and acoustic holes) Another form of the present invention is a disaster prevention device, in which a transmitter, an indicator lamp, and an acoustic hole area are provided in a concentrated manner in a housing case, and the indicator lamp has display surfaces on the front and side surfaces of the housing case.

[0022] (Arrangement of indicator lamp provided with acoustic hole and transmitter) The display surface of the indicator lamp is provided at a position surrounding the transmitter, at a position surrounding a part of the periphery of the transmitter, or at a position sandwiching the transmitter from above and below and / or left and right, and acoustic holes are provided on at least the front display surface of the indicator lamp.

[0025] (Relationship between the transmitter and the housing case) The top exposure height of the exposed part (e.g., maintenance door, push button) of the transmitter shall be equal to or less than the display surface exposure height of the front surface of the display surface.

[0026] (The 7th invention: Overlap of the acoustic hole area, the transmitter arrangement area, and the indicator light) Another form of the present invention is a disaster prevention device, characterized in that the acoustic hole area, the transmitter arrangement area, and the indicator light are arranged such that their arrangement positions overlap at least partially in the vertical or horizontal direction (up and down or left and right direction) in the installed state.

[0027] For example, the indicator light has a display surface on at least one of the left and right side surfaces of the housing case in the installed state. Also, the indicator light is provided with acoustic holes on at least one of the left and right side surfaces of the housing case in the installed state, and / or at least one of the upper and lower surfaces.

Effect of the invention

[0028] (Effect of the integrated arrangement of the indicator light and the acoustic hole of the disaster prevention device of the 1st invention) The present invention is a disaster prevention device characterized in that a display lamp and an acoustic hole area are provided in a concentrated manner in one place. For example, an opening and / or a notch are provided in the display lamp, and an acoustic hole is provided in at least one of the opening and / or the notch. Therefore, by concentrating the arrangement of the display lamp that functions as a notification unit and the acoustic hole area, the installation space is reduced, the disaster prevention device is miniaturized, and the confusion of the operator caused by integrating a transmitter that functions as an operation unit and a display lamp that functions as a notification unit as in the prior art can be reliably avoided. Further, even when the arrangement of the acoustic hole area and the display lamp is concentrated, the arrangement and shape of the display lamp are not restricted by the arrangement of the acoustic hole area, the degree of freedom in the arrangement and shape of the display lamp is high, and the design property can be enhanced.

[0029] (Second Invention: Effects of Concentrated Arrangement of Display Lamp, Acoustic Hole, and Transmitter of Disaster Prevention Device) Another form of the present invention is a disaster prevention device characterized in that a transmitter, a display lamp, and an acoustic hole area are provided in a concentrated manner in one place. For example, a display lamp is provided so as to surround the transmitter, and an acoustic hole area is provided in at least one of the gap between the transmitter and the display lamp, the opening of the display lamp, and the notch of the display lamp. Therefore, by concentrating the arrangement of the display lamp, the acoustic hole, and the transmitter, the installation space is further reduced, and the disaster prevention device can be further miniaturized.

[0030] (Effect of Flat Structure of Display Lamp) Further, the display lamp has a substantially flat display frame along the exposed surface of the disaster prevention device. The display frame is a diffusing and light-transmitting member, and a light source for illuminating the diffusing and light-transmitting member is provided behind the display frame. Therefore, the display part of the display lamp becomes a substantially flat display frame along the exposed surface of the disaster prevention device, and various display patterns for improving visibility from the front and side can be easily formed. By becoming a substantially flat display frame along the exposed surface of the disaster prevention device, various display patterns for improving visibility from the front and side can be easily formed.

[0031] (Effect of Shape of Display Frame) Further, since the display frame of the display lamp is formed in a frame shape, a lattice shape, a ring shape, or a divided ring shape, various forms are possible while ensuring visibility from the front and side, and the design property can be enhanced.

[0032] (Effect of integration of display lamp and sound hole) In addition, since the sound hole is provided in the display lamp, it is not necessary to process and form the sound hole in the cover plate of the disaster prevention device, and thus the structure can be simplified accordingly.

[0033] (Third Invention: Effect of sound path functioning as sound hole) Another form of the present invention is a disaster prevention device in which a sound path functioning as a sound hole is provided behind the display lamp and / or the display lamp. Therefore, due to the formation of the sound path, sound can be output and diffused efficiently. Also, when the sound path is provided only behind the display lamp, the sound path is hidden by the display lamp and cannot be seen from the front, thereby obtaining a new design property and improving the design property.

[0034] (Fourth Invention: Effect of sound horn) Another form of the present invention is a disaster prevention device that notifies predetermined information by the display of the display lamp and the sound from the sound hole. A sound horn is formed in the display lamp, and predetermined information is output by the sound from the sound hole via the sound horn. Therefore, the sound from the sound device can be output and diffused efficiently to the outside, and also, the design property can be greatly improved by the formation of the sound horn.

[0035] (Effect of Fifth Invention) Another form of the present invention is a disaster prevention device in which the display lamp and the sound hole area are concentrated in one place in the housing case, and the display lamp has display surfaces on the front and side surfaces of the housing case. By doing so, while miniaturizing the disaster prevention device, it is possible to surely avoid the confusion of the operator caused by integrating the transmitter functioning as an operation unit and the display lamp functioning as a notification unit as in the conventional case. When the disaster prevention device is installed on a wall surface or the like, the visibility from the side can be improved while maintaining the visibility from the front, and the design property can also be enhanced.

[0036] (Effect of arrangement of display lamp and sound hole area) In addition, since the display surface of the indicator light is provided at a position surrounding a part or all of the periphery of the sound hole area, or at a position sandwiching from above and below and / or left and right, various display surface shapes and arrangements can be made. When the disaster prevention device is installed on a wall surface or the like, the visibility of the indicator light from the front and side directions is ensured, the degree of freedom in the arrangement and shape of the display surface is high, and the design quality can be enhanced.

[0037] (Effect of the display surface of the indicator light provided with the sound hole area) Furthermore, since the sound hole area is provided on the front surface of the display frame of the indicator light, the restriction that the shape and arrangement of the display frame are restricted by the sound hole area is alleviated, and the degree of freedom regarding the shape and arrangement of the display frame can be increased.

[0038] (Effect of the overlapping arrangement of the area of the indicator light and the area of the sound hole) Also, in the first invention, the second invention, and the fifth invention, since the display surface of the indicator light and the sound hole area are arranged so that at least a part thereof overlaps with each other, restrictions such as the space for arranging the indicator light and the sound hole on the front surface of the device are alleviated, and the degree of freedom in design can be improved.

[0039] (Effect of the sixth invention) Another form of the present invention is a disaster prevention device, in which a transmitter, an indicator light, and a sound hole area are intensively provided at one location on the front surface of the housing case, and the indicator light has display surfaces on the front surface and the side surface of the housing case, so that the disaster prevention device can be further miniaturized. Also, when the disaster prevention device is installed on a wall surface or the like, while ensuring the visibility from the front, the visibility from the side is improved, and the design quality can also be enhanced.

[0040] (Effect of the arrangement of the indicator light provided with the sound hole and the transmitter) Also, the display surface of the indicator light is provided at a position surrounding the periphery of the transmitter, at a position surrounding a part or all of the periphery of the transmitter, or at a position sandwiching the transmitter from above and below and / or left and right, and since the sound hole is provided on at least the front display surface of the indicator light, the display frame is not restricted by the arrangement of the sound hole area, and the degree of freedom regarding the shape and arrangement of the display frame can be increased.

[0041] (Effect of the separation structure between the push-button switch and the transmitter body) In addition, the transmitters of the second and sixth inventions are separated into a transmitter body, a push-button switch provided with a protection plate, and a maintenance door. The push-button switch and the maintenance door are provided on the front surface of the housing case, and the transmitter body is provided inside the housing case. Therefore, only the push-button switch with a protection cover of the transmitter and the maintenance door are provided on the front surface of the housing case, so that the degree of freedom in arranging the indicator lights and the acoustic hole areas is greatly improved, and the size of the housing case can be significantly reduced compared to the case where the transmitter is directly provided on the front surface of the housing case, and the entire disaster prevention device can be further miniaturized.

[0042] (Effect due to the relationship between the indicator light and the housing case) In addition, since the display surface of the indicator light is flush with the front surface of the housing case or the front surface and the side surface of the housing case, the display surface of the indicator light is substantially flat along the front surface of the housing case or the front surface and the side surface, so that the design property is improved. Also, by suppressing the protrusion of the indicator light from the housing case surface, it can be made thinner, and various display patterns for improving the visibility from the front and side directions can be easily formed.

[0043] (Effect due to the relationship between the transmitter and the housing case) In addition, since the top exposure height of the exposed part (maintenance door, push button) of the transmitter is set to be equal to or less than the display surface exposure height of the front surface of the display surface, the protrusion of the transmitter operation part from the housing case surface can be suppressed, and malfunction due to contact with people or objects can be prevented, and an improvement in design property can be expected.

[0044] (Seventh Invention: Overlap of the acoustic 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, the transmitter arrangement area, and the indicator light are arranged such that their arrangement positions overlap at least partially in the vertical or horizontal direction (vertical or horizontal direction) in the installed state. Therefore, restrictions on the space for arranging the acoustic holes, the transmitter, and the indicator light are relaxed, and the degree of freedom in design can be improved.

[0045] In addition, for example, the indicator lamp has a display surface on at least one of the left and right side surfaces of the housing case in the installed state, and the indicator lamp is provided with sound holes on at least one of the left and right side surfaces and / or at least one of the upper and lower surfaces of the housing case in the installed state, so that visibility from the side, above, and below can be ensured and improved.

Embodiments for Carrying Out the Invention

[0047] As an embodiment of the disaster prevention device of the present invention, taking a disaster prevention equipment storage box equipped with an indicator light for displaying the location of the device as predetermined display notification information, an acoustic hole for outputting a fire alarm sound as predetermined sound notification information, and a transmitter for outputting a fire notification signal by switch operation as an example. Note that the disaster prevention equipment storage box is also simply called an equipment storage box.

[0048] [Basic Concept of Embodiment: First Invention] FIG. 1 is an explanatory diagram showing a first embodiment of a disaster prevention equipment storage box in which a position indicator light and an acoustic hole are intensively arranged in one place as an example of the 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 light taken out and shown from behind.

[0049] The basic concept of this embodiment is a disaster prevention equipment storage box 10, in which an opening 14a and / or a notch are provided in the position indicator lamp 14, and an acoustic hole 16 is provided in at least a part of at least one of the opening 14a and / or the notch. The position indicator lamp 14 that functions as a notification unit and the acoustic hole 16 are integrated in one place to reduce the installation space and miniaturize the disaster prevention equipment storage box 10. The transmitter 12, which is an operation unit, is separated from the position indicator lamp 14 and the acoustic hole 16, which are notification units, so that the user will not be confused.

[0050] Also, even if the acoustic hole 16 and the position indicator lamp 14 are integrated and arranged in one place, the arrangement and shape of the position indicator lamp 14 are not restricted by the arrangement of the acoustic hole 16, and the degree of freedom in the arrangement and shape of the position indicator lamp 14 is high, so the design can be enhanced.

[0051] In another embodiment of the present invention, a position indicator lamp is provided so as to surround the transmitter, and an acoustic hole is provided in at least one of the gap between the transmitter and the position indicator lamp, the opening of the position indicator lamp, and the notch of the position indicator lamp. Therefore, in addition to the same improvement in operability and design as the disaster prevention equipment storage box 10 shown in FIG. 1, the installation space is further reduced by arranging the position indicator lamp, the acoustic hole, and the transmitter in one place, and the disaster prevention equipment storage box can be made even smaller.

[0052] In this case, the operation unit and the notification unit are arranged together in one place, so that when the user operates, there is no confusion about which is the operation unit and which is the notification unit.

[0053] [First Embodiment of Disaster Prevention Equipment Storage Box: First Invention] (Overview of Disaster Prevention Equipment Storage Box) As shown in FIG. 1(A), in the disaster prevention equipment storage box 10 of the first embodiment, the transmitter 12 is arranged below the exposed surface of the cover plate 10a that is exposed when installed on a wall surface or the like, and the acoustic hole 16 and the position indicator lamp 14 are integrally arranged above it. 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.

[0054] The transmitter 12 is provided, at its center, with a protective plate 18 made of a transparent acrylic plate or the like for turning on the built-in push-button switch 20, and a maintenance door 22 with a telephone jack arranged inside.

[0055] The position indicator lamp 14 has a rectangular frame display frame 28a. An opening 14a is formed inside the frame display frame 28a. A plurality of acoustic holes 16 are formed on the plate surface located in the opening 14a. The position indicator lamp 14 and the acoustic holes 16 are intensively arranged in one place. As shown in FIG. 1(B), the acoustic holes 16 may be provided outside the frame display frame 28a.

[0056] In FIG. 1(B), by arranging the unit 15 provided with the position indicator lamp 14 and the acoustic holes 16 on the cover plate 10a, the area where the acoustic holes 16 are arranged (the acoustic hole area 16a indicated by the imaginary line) and the display surface of the position indicator lamp 14 (here, the front surface of the frame display frame 28a) overlap each other. Here, the center of the acoustic hole area and the center of the frame display frame 28a (the center of the opening 14a) may be offset so that a part of the display surface overlaps the acoustic hole area in a front view.

[0057] As shown in FIG. 2, the disaster prevention equipment storage box 10 is composed of a cover plate 10a and a box-shaped main body 10b to form a storage case. An acoustic device 24 such as a buzzer or a bell is arranged at a position in the main body 10b opposite to the back of the position indicator lamp 14 attached to the cover plate 10a. When the acoustic device 24 is sounded by the area acoustic signal from the receiver, the fire alarm sound is output from the acoustic holes 16 arranged in the rectangular opening 14a in the frame display frame 28a of the position indicator lamp 14 shown in FIG. 1.

[0058] As shown in FIG. 3, the position indicator lamp 14 has a sealing portion 36 arranged and closed in the opening 14a of the frame display frame 28a. A plurality of acoustic holes 16 shown in FIG. 1 are provided in the sealing portion 36. A cylindrical attachment portion 38 extends from behind the sealing portion 36. By fitting the cylindrical attachment portion 38 into the attachment hole of the cover plate 10a shown in FIG. 2, the position indicator lamp 14 can be attached to the cover plate 10a.

[0059] Further, the cylindrical attachment portion 38 is located in front of the acoustic device 24 disposed in the main body 10b, and also serves as an acoustic introduction case that introduces the fire alarm sound generated by driving the acoustic device 24 and outputs it forward from the acoustic hole 16.

[0060] (Structure of the position indicator lamp) FIG. 4 is a cross-sectional view showing the internal structures of the acoustic hole and the position indicator lamp in FIG. 3. As shown in FIG. 4, the position indicator lamp 14 includes an annular display lamp case 26 that has a U-shaped cross-section and is open in the front. An LED accommodation portion 30 is formed in the display lamp case 26, and for example, a frame-shaped circuit board 34 is disposed on the bottom side. LEDs 32 that function as light sources are arranged on the circuit board 34 at predetermined intervals.

[0061] A rectangular frame display frame 28a is disposed at the front opening of the display lamp case 26. A diffusing and light-transmitting member that emits red light is used for the frame display frame 28a. The diffusing and light-transmitting member is a member that converts the light from the point light source by the LED 32 into surface light emission. The light from the backlight illumination of the LEDs 32 arranged in a ring shape at predetermined intervals on the circuit board 34 is incident on the frame display frame 28a using the diffusing and light-transmitting member, and the entire display surface of the frame display frame 28a is made to emit surface light in a substantially uniform red color as a display area (light-emitting area).

[0062] Also, the display surface of the frame display frame 28a is formed as an inclined display surface that protrudes slightly forward on the inner peripheral side with respect to the outer peripheral side, and the visibility when viewing the position indicator lamp 14 from the lateral direction is enhanced by this inclined display surface. Note that a curved display surface may be used instead of the inclined display surface.

[0063] Inside the display lamp case 26 of the position indicator lamp 14, a rectangular opening 14a is formed, and the opening 14a is closed by fitting the sealing portion 36. The sealing portion 36 is a box-shaped member having a sealing surface 36a in the front. As shown in FIG. 1, a plurality of acoustic holes 16 are formed in the acoustic hole region 16a (the region surrounded by the two-dot chain line in the figure) on the sealing surface 36a. A cylindrical attachment portion 38 extends from the rear of the sealing portion 36. By fitting the cylindrical attachment portion 38 into the attachment hole 35 formed in the cover plate 10a, the position indicator lamp 14 can be attached and fixed to the cover plate 10a.

[0064] Further, the rear opening of the cylindrical attachment portion 38 faces the acoustic device 24 disposed in the main body 10b shown in FIG. 2. It 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 holes 16 formed in the sealing surface 36a.

[0065] Note that the attachment structure of the position indicator lamp 14 to the cover plate 10a is not limited to that shown in FIG. 4, and can be an appropriate attachment structure.

[0066] Thus, in the first embodiment, by forming the acoustic holes 16 in the rectangular opening 14a located inside the frame display frame 28a of the position indicator lamp 14, the position indicator lamp 14 and the acoustic holes 16 are concentrated and arranged in one place. Therefore, in addition to reducing the installation space and miniaturizing the disaster prevention equipment housing box 10, the position indicator lamp 14 and the acoustic holes 16 that function as the notification unit are concentrated and arranged in one place, and the operator is not confused as in the case where the transmitter 12 that functions as the conventional operation unit and the position indicator lamp that functions as the notification unit are integrated. The operability in an emergency such as a fire can be improved.

[0067] Further, by making the outer edge of the position indicator lamp 14 into a rectangular ring shape by the frame display frame 28a, a clear contour is given to the acoustic hole array portion where the acoustic holes 16 are arranged, and the design can also be enhanced thereby.

[0068] (Cosmetic frame of the transmitter) FIG. 5 is an explanatory view showing a disaster prevention equipment storage box provided with a decorative frame on the transmitter side of FIG. 1. As shown in FIG. 5, in the present embodiment, for the disaster prevention equipment storage box 10 of the first embodiment shown in FIG. 1, a decorative frame 40 is provided on the plate surface surrounding the transmitter 12 arranged on the cover plate 10a by a decorative frame member, painting, a sealing tape, etc.

[0069] Therefore, by making the outer edge of the position indicator lamp 14 into a rectangular ring shape by the frame display frame 28a, in addition to giving a clear contour to the acoustic hole array portion where the acoustic holes 16 are arranged, a decorative frame 40 of the same shape is provided on the transmitter 12 to give a clear contour. When the disaster prevention equipment storage box 10 of the present embodiment is installed on a wall surface or the like, the integrity is improved, and the design can be further enhanced.

[0070] [Second Embodiment of Disaster Prevention Equipment Storage Device] FIG. 6 is an explanatory view showing a second embodiment of the disaster prevention equipment storage box. As shown in FIG. 6, the disaster prevention equipment storage box 10 of the present embodiment is provided with a grid display frame 28b on the position indicator lamp 14, and a plurality of acoustic holes 16 are provided in each of, for example, four openings partitioned by the grid display frame 28b. The other structures are the same as those of the first embodiment, and the same operational effects can be obtained.

[0071] Also, in the present embodiment, by providing the grid display frame 28b on the position indicator lamp 14, the display area (the display area area of the display surface) is increased, the visibility is improved, and a strong impression can also be given design-wise.

[0072] [Third Embodiment of Disaster Prevention Equipment Storage Device] FIG. 7 is an explanatory view showing a third embodiment of the disaster prevention equipment storage box. As shown in FIG. 7, the disaster prevention equipment storage box 10 of the present embodiment is provided with an annular display frame 28c on the position indicator lamp 14, and a plurality of acoustic holes 16 are provided in a circular opening partitioned by the annular display frame 28c. The other structures are the same as those of the first embodiment, and the same operational effects can be obtained.

[0073] In addition, in the present embodiment, by providing the annular display frame 28c on the position indicator lamp 14, the unity with the circular transmitter 12 is improved, and the design of the disaster prevention equipment storage box 10 of the present embodiment can be enhanced.

[0074] [Fourth Embodiment of Disaster Prevention Equipment Storage Device] FIG. 8 is an explanatory diagram showing a fourth embodiment of the disaster prevention equipment storage box. As shown in FIG. 8, the disaster prevention equipment storage box 10 of the present embodiment is provided with an annular display frame 28d formed by combining an annulus and a cross on the position indicator lamp 14, and a plurality of acoustic holes 16 are provided in each of the four fan-shaped openings partitioned by the annular display frame 28d. The other structures are the same as those in the first embodiment, and the same operational effects can be obtained.

[0075] In addition, in the present embodiment, by providing the annular display frame 28d formed by combining an annulus and a cross on the position indicator lamp 14, the unity with the circular transmitter 12 is improved, and further, the display area (the display area area of the display surface) is increased, the visibility is improved, and a strong impression can also be given in terms of design.

[0076] [Fifth Embodiment of Disaster Prevention Equipment Storage Device] FIG. 9 is an explanatory diagram showing a fifth embodiment of the disaster prevention equipment storage box.

[0080] [Embodiment in which the transmitter, position indicator lamp, and acoustic holes are intensively arranged: Second Invention] FIG. 11 is an explanatory view showing an embodiment of a disaster prevention equipment storage box in which the transmitter, position indicator lamp, and acoustic holes are intensively arranged in one place.

[0081] In this embodiment, on the cover plate 10a of the disaster prevention equipment storage box 10, a position indicator lamp 14 composed of four annular display frames 28g divided at four locations on the left, right, upper, and lower sides so as to surround the transmitter 12 is provided. Acoustic holes 16 are provided in each of the gap portion 14b between the transmitter 12 and the position indicator lamp 14, which becomes the acoustic hole region 16a surrounded by the imaginary line, and the notch portion 14c of the position indicator lamp 14.

[0082] According to this embodiment, in addition to the same operability and improvement in design as in the first embodiment, the installation space is further reduced by the intensive arrangement of the transmitter 12, the position indicator lamp 14, and the acoustic holes 16 in one place, and the disaster prevention equipment storage box can be made even smaller.

[0083] Note that, as the form of the display frame of the position indicator lamp 14 in this embodiment, an annular form shown in FIG. 7, FIG. 9, or FIG. 10 can also be provided.

[0084] [Fire hydrant device] FIG. 12 is an explanatory diagram showing an embodiment of a fire hydrant device in which a position indicator lamp and a sound hole are intensively arranged in one place.

[0085] As shown in FIG. 12, in the fire hydrant device 50 of this embodiment, a fire hydrant door 54 is provided on the front surface of a metal storage box 52 so as to be openable and closable. A notification panel 56 is provided above the fire hydrant door 54. A transmitter 12 is provided on the cover plate 10a of the notification panel 56, and the sound hole 16 and the position indicator lamp 14 are intensively arranged in one place. Inside the fire hydrant door 54, a hose with a nozzle is stored.

[0086] The position indicator lamp 14 is the same as the position indicator lamp 14 provided in the disaster prevention equipment storage box 10 of FIG. 1. It has a rectangular frame display frame 28a. An opening 14a is formed inside the frame display frame 28a, and a sound hole 16 is formed on the plate surface located in the opening 14a.

[0087] Also in this embodiment, by intensively installing the position indicator lamp 14 and the sound hole 16 that function as a notification unit in one place, the installation space of the notification panel 56 provided in the fire hydrant box 50 is reduced, and the transmitter 12 which is an operation unit and the position indicator lamp 14 and the sound hole 16 which are notification units are separated so that users will not be confused.

[0088] Further, even if the sound hole 16 and the position indicator lamp 14 are intensively arranged in one place, the arrangement and shape of the position indicator lamp 14 are not restricted by the arrangement of the sound hole 16, and the degree of freedom in the arrangement and shape of the position indicator lamp 14 is high, and the design can be enhanced.

[0089] In addition, by making the outer edge of the position indicator lamp 14 into a rectangular ring shape by the frame display frame 28a, a clear contour is given to the sound hole array portion where the sound hole 16 is arranged, and thereby the design can be enhanced.

[0090] Note that the notification panel 56 in FIG. 12 may be provided with the same position indicator lamp 14 as that provided in the disaster prevention equipment storage box 10 of FIGS. 6, 7, 8, 9 or 10.

[0091] FIG. 13 is an explanatory diagram showing an embodiment of a fire hydrant device in which a transmitter, a position indicator lamp, and a sound hole are intensively arranged in one place.

[0092] As shown in FIG. 13, in the fire hydrant device 50 of this embodiment, a transmitter 12, a position indicator lamp 14, and a sound hole 16 are intensively provided in one place on a cover plate 10a of a notification panel 56 provided above a fire hydrant door 54.

[0093] The position indicator lamp 14 is the same as the position indicator lamp 14 provided in the disaster prevention equipment storage box 10 of FIG. 11. On the notification panel 56, a position indicator lamp 14 composed of a divided annular display frame 28g divided into four locations on the left, right, top, and bottom so as to surround the transmitter 12 is provided. Sound holes 16 are provided in each of the gap between the transmitter 12 and the position indicator lamp 14, the opening of the position indicator lamp 14, and the notch of the position indicator lamp 14.

[0094] According to this embodiment, in addition to the same improvement in operability and design as in FIG. 12, the installation space can be further reduced by arranging the transmitter 12, the position indicator lamp 14, and the sound hole 16 in one place.

[0095] [Embodiment in which a position indicator lamp and a sound hole are intensively arranged on a cover plate] FIG. 14 is an explanatory diagram showing an embodiment of a disaster prevention equipment storage box in which a position indicator lamp and a sound hole are intensively arranged on a cover plate.

Such a structure can simplify the structure in which the position indicator lamp 14 and the sound hole 16 are intensively arranged in one place. Of course, it can be similarly applied to the case of a fire hydrant device.

[0097] [Embodiment of a disaster prevention equipment storage box in which a sound hole is provided in a position indicator lamp] FIG. 15 is an explanatory diagram showing an embodiment of a disaster prevention equipment storage box provided with a sound hole in a position indicator light, FIG. 16 is an explanatory diagram showing the position indicator light in FIG. 15 taken out and showing the internal structure, and FIG. 17 is an explanatory diagram showing the front and plane cross-sections of the position indicator light in FIG. 15 taken out.

[0098] As shown in FIG. 15, in the disaster prevention equipment storage box 10 of this embodiment, a transmitter 12 is arranged below the exposed surface of the cover plate 10a, and a circular position indicator light 14 is arranged above it. The position indicator light 14 is provided with a sound hole 16.

[0099] As shown in FIGS. 16(A) and 17(A), in the circular display frame 28h of the position indicator light 14, the sound hole 16 is provided in the sound hole region 16a in a double annular arrangement. Also, as shown by the dotted line in FIGS. 15 and 17(A), an LED 32 is provided inside the circular display frame 28h, and the LED 32 is provided at the central part of the position indicator light 14 and in a double annular arrangement outside it. Also, a mounting cylindrical portion 38 is provided behind the circular display frame 28h, enabling front fitting and fixing to the mounting hole 35 of the cover plate 10a.

[0100] The internal structure of the position indicator light 14 is shown in FIGS. 16(B) and 17(B). Note that FIG. 17(B) is a plane cross-section of the position indicator light 14 as seen in the X-X cross-section of FIG. 16(B).

[0101] As shown in FIGS. 16(B) and 17(B), the circular display frame 28h uses a red diffusing and light-transmitting member, and a cylindrical mounting portion 38 is integrally formed behind it. Following the outer peripheral rib 60 reaching the cylindrical mounting portion 38 toward the back side, annular ribs 62a, 62b, 62c are arranged concentrically inside it, and LED storage portions 64a, 64b, 64c are formed between each of the outer peripheral rib 60 and the annular ribs 62a, 62b and at the central part.

[0102] In each of the annular ribs 62a and 62b, a plurality of acoustic holes are formed in a penetrating state. Further, a circular circuit board 34 is disposed at the bottom of the cylindrical mounting portion 38 behind the circular display frame 28h. An opening hole 34a is formed at a position corresponding to the acoustic hole 16 of the circuit board 34, and the sound from the acoustic device 24 disposed in the main body 10b is output to the outside through the acoustic hole 16 of the position display lamp 14 by communicating with the acoustic hole 16 and penetrating inside. Note that the acoustic device 24 may be directly attached to the cylindrical mounting portion 38.

[0103] As shown in FIG. 17(B), a plurality of LEDs 32 are arranged on the circuit board 34 so as to correspond to the concentric LED housing portions 64a, 64b, and 64c arranged concentrically. For example, one LED 32 is arranged in the central LED housing portion 64c, and, for example, eight LEDs are arranged at 45° intervals in the outer concentric LED housing portions 64b and 64a.

[0104] By driving a plurality of LEDs 32 arranged on the circuit board 34 in this way, the light from the LEDs 32 is incident on the circular display frame 28h using the diffusion light-transmitting member, and the entire surface of the position display lamp 14 emits surface light in a substantially uniform red color.

[0105] In this embodiment, by providing the acoustic hole 16 in the position display lamp 14, in addition to the same operability and improvement in design as in the first embodiment, it is not necessary to process and form the acoustic hole in the cover plate 10a of the disaster prevention equipment storage box 10, and thus the structure can be simplified accordingly.

[0106] Note that the arrangement of the acoustic hole 16 and the LEDs 32 with respect to the circular display frame 28h of the position display lamp 14 is an example and is not limited thereto. For example, the acoustic hole 16 and the LEDs 32 may be arranged alternately in a radial pattern.

[0107] Also, for the embodiments of FIGS. 1, 5 to 10, the structure may be such that the acoustic hole 16 is provided in the display frame provided in each embodiment. Further, this embodiment may be provided in the fire hydrant device 50 as shown in FIGS. 12 and 13.

[0108] [Embodiment in which the transmitter, position indicator light, and sound holes of the disaster prevention equipment storage box are intensively arranged] FIG. 18 is an explanatory diagram showing another embodiment of a disaster prevention equipment storage box in which a transmitter, a position indicator light, and sound holes are intensively arranged in one place.

[0109] As shown in FIG. 18, in this embodiment, on the cover plate 10a of the disaster prevention equipment storage box 10, a position indicator light 14 composed of two split annular display frames 28i split at two positions on the left and right so as to surround the transmitter 12 is provided, and a plurality of sound holes 16 are provided on the outer peripheral side and the inner peripheral side of the split annular display frame 28i in the position indicator light 14.

[0110] According to this embodiment, in addition to the same operability and improved design as in the first embodiment, the installation space is further reduced by the intensive arrangement of the transmitter 12, the position indicator light 14, and the sound holes 16 in one place, and the processing and formation of the sound holes on the cover plate 10a of the disaster prevention equipment storage box 10 are not required, and accordingly, the structure can be simplified.

[0111] Note that the form of the display frame provided with the sound holes 16 of the position indicator light 14 in this embodiment can, of course, also be provided with the sound holes 16 in the same manner as in FIG. 18 for the position indicator light 14 in FIG. 11. The shape of the display frame of the position indicator light 14 can be applied to other embodiments and others. Further, this embodiment may be provided in the fire hydrant device 50 as shown in FIG. 13.

[0112] [Embodiment of a disaster prevention equipment storage box in which the position indicator light is provided with sound holes] FIG. 19 is an explanatory diagram showing another embodiment of a disaster prevention equipment storage box in which the position indicator light is provided with sound holes, and FIG. 20 is an explanatory diagram showing a cross section of the position indicator light in FIG. 19. FIG. 20(A) shows the A-A cross section, and FIG. 20(B) shows the B-B cross section.

[0113] As shown in FIG. 19, in the disaster prevention equipment storage box 10 of this embodiment, the transmitter 12 is arranged below the exposed surface of the cover plate 10a, the rectangular position indicator light 14 is arranged above it, and the position indicator light 14 is provided with sound holes 16 (sound holes on the display light side).

[0114] As shown in FIGS. 19 and 20(A), for the rectangular display frame 28j of the position indicator lamp 14, for example, three acoustic holes 16 that open conically toward the front side are provided in three rows and three columns. At positions corresponding to the acoustic holes 16 of the cover plate 10a, acoustic holes 16a (cover plate side acoustic holes) are provided, and the sound from the acoustic device 24 disposed in the main body 10b is output to the outside through the acoustic holes 16a of the cover plate 10a and the acoustic holes 16 of the position indicator lamp 14. That is, in this case, the acoustic holes 16 (display lamp side acoustic holes) also correspond to the openings.

[0115] Also, as shown by the dotted line in FIG. 19, behind the rectangular display frame 28j, LEDs 32 are provided, for example, two by two in two rows and two columns at positions between the acoustic holes 16. As shown in FIG. 20(B), the cover plate 10a located on the back surface of the rectangular display frame 28j is provided with light-transmitting holes 70, a circuit board 34 is disposed on the back surface of the cover plate 10a, and the LEDs 32 are disposed at positions corresponding to the light-transmitting holes 70 of the cover plate 10a of the circuit board 34. By driving the LEDs 32 to emit light, the light from the LEDs 32 enters the rectangular display frame 28j using a diffusion light-transmitting member through the light-transmitting holes 70, and the entire surface of the position indicator lamp 14 is made to emit surface light in a substantially uniform red color.

[0116] In this embodiment, by providing the acoustic holes so as to communicate the position indicator lamp 14 and the cover plate 10a, in addition to the same improvement in operability and design as in the first embodiment, the structure of aggregating and arranging the position indicator lamp 14 and the acoustic holes 16 in one place can be simplified.

[0117] Note that the center of the rectangular display frame 28j and the arrangement area of the cover plate side acoustic holes may be offset, for example, vertically. Also in this case, the cover plate side acoustic holes and the display lamp side acoustic holes may be provided at corresponding positions. Then, the display surface and the acoustic hole area will partially overlap in a front view.

[0118] Also, the arrangement of the acoustic holes 16 and the LEDs 32 with respect to the display surface of the rectangular display frame 28j of the position indicator lamp 14 in this embodiment is an example and is not limited thereto, and an appropriate arrangement may be adopted.

[0119] Also, for the embodiments of FIGS. 1, 5 to 10, the position indicator lamp 14 and the sound hole 16 provided in each embodiment may be provided on the cover plate 10a. Further, as shown in FIGS. 12 and 13, it may be provided in the fire hydrant device 50. Furthermore, the configurations of FIGS. 19 and 20 may be combined with the configurations of other embodiments.

[0120] [Embodiment of a disaster prevention equipment storage box with an acoustic path formed in a position indicator lamp: Third invention] FIG. 21 is an explanatory view showing an embodiment of a disaster prevention equipment storage box with an acoustic path formed in a position indicator lamp, and FIG. 22 is an explanatory view showing a cross-section of the position indicator lamp in FIG. 21.

[0121] As shown in FIG. 21, 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 the rectangular position indicator lamp 14 is disposed above it.

[0122] As shown in FIG. 22, in the rectangular display frame 28k of the position indicator lamp 14, a protruding portion 77 having a rectangular cross-section and extending in a conical shape is formed behind the rectangular frame on the front surface. The protruding portion 77 is fixed to the front surface of the cover plate 10a by a screw 62 via a spacer 78 so as to be positioned with a gap between the front surface (exposed surface) of the cover plate 10a in the mounting hole 75 formed in the cover plate 10a. Thus, an acoustic path 72 leading to the outside from the gap of the mounting hole 75 is formed between the cover plate 10a and the rectangular display frame 28k. Note that the acoustic path 72 realizes the same function as that of forming a sound hole.

[0123] Therefore, the sound from the acoustic device 24 disposed in the main body 10b passes through the acoustic path 72 formed behind the rectangular display frame 28k from the gap of the mounting hole 75 and is output to the outside along the path indicated by the arrow 76.

[0124] In addition, an LED storage portion 74 is formed in a protrusion 77 formed behind 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 using a diffusing and light-transmitting member, and the entire surface of the position indicator light 14 emits surface light in a substantially uniform red color.

[0125] In this way, in the present embodiment, by forming the acoustic path 72 behind the position indicator light 14, a passage for sound corresponding to forming a plurality of acoustic holes is secured, and sound can be output efficiently. Further, the acoustic path 72 is hidden by the position indicator light 14 and is not visible, and a new design property as a disaster prevention equipment storage box 10 without acoustic holes is obtained, and it is possible to greatly improve the design property.

[0126] Note that, in order to adjust the sound output performance and diffusion performance, it is not prohibited to provide acoustic holes in the rectangular display frame 28k of the position indicator light 14. Further, similar to the embodiment of FIG. 1(B), it is not prohibited to provide acoustic holes in the cover plate 10a outside the display frame.

[0127] In addition, the arrangement of the acoustic path 72 and the LED 32 formed behind the position indicator light 14 in the present embodiment is an example and is not limited thereto, and an appropriate arrangement may be used. Further, as shown in FIGS. 12 and 13, the present embodiment may be provided in a fire hydrant device 50. Further, the display frame may be other than rectangular, for example, circular. Of course, the protrusion may also have other shapes.

[0128] [Embodiment of a disaster prevention equipment storage box with an acoustic horn formed in a position indicator light: Fourth Invention] FIG. 23 is an explanatory view showing an embodiment of a disaster prevention equipment storage box with an acoustic horn formed in a position indicator light, and FIG. 24 is an explanatory view showing a central cross section of the position indicator light in FIG. 23.

[0129] As shown in Fig. 23, in the disaster prevention equipment storage box 10 of this embodiment, the transmitter 12 is arranged on the lower side of the exposed surface of the cover plate 10a, the rectangular position indicator lamp 14 is arranged on the upper side thereof, a rectangular sound hole 16 is formed in the center of the position indicator lamp 14, and a sound horn 80 that opens in a conical shape with the sound hole 16 as the center is formed.

[0130] As shown in Fig. 24, the rectangular display frame 28m of the position indicator lamp 14 penetrates through the sound hole 16 which is a rectangular hole in the center of the protruding portion 82 with a rectangular cross-section formed at the center of the back. The front side of the sound hole 16 gradually expands, thereby forming the sound horn 80 on the front surface of the rectangular display frame 28m. Therefore, the sound from the sound device 24 arranged on the main body 10b passes through the sound hole 16 and is output and diffused to the outside by the sound horn 80.

[0131] 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 arranged on the back surface of the cover plate 10a, and an LED 32 is arranged at a position corresponding to the light-transmitting hole 70 of the cover plate 10a on the circuit board 34. By driving the LED 32 to emit light, the light from the LED 32 enters the rectangular display frame 28m using a light-diffusing member through the light-transmitting hole 70, and the entire surface of the position indicator lamp 14 emits surface light in a substantially uniform red color.

[0132] In this way, in this embodiment, by forming the sound hole 16 and the sound horn 80 in the position indicator lamp 14, in addition to reducing the installation space, the sound from the sound device 24 can be efficiently output and diffused to the outside, and the design can be greatly improved by forming the sound horn 80.

[0133] In addition, in order to adjust the sound output performance and diffusion performance, it is not prohibited to provide a sound hole in the rectangular display frame 28m of the indicator lamp 14. Furthermore, similar to the embodiment in Fig. 1(B), it is not prohibited to provide a sound hole in the cover plate 10a outside the display frame. In this case, when providing a sound hole in the display frame, a sound hole should also be provided at the corresponding position of the cover plate 10a.

[0134] Note that the shape and arrangement of the sound holes 16 and the sound path 72 formed in the position indicator lamp 14 in this embodiment are merely examples and are not limited thereto. Appropriate shapes and arrangements may be adopted. Further, as shown in FIGS. 12 and 13, this embodiment may be provided in the fire hydrant device 50. Also, the display frame may be other than rectangular, for example, it may be circular. Of course, the protrusion may also have other shapes.

[0135] [Embodiment of a disaster prevention equipment storage box with a sound path and a sound horn formed in a position indicator lamp] FIG. 25 is an explanatory diagram showing an embodiment of a disaster prevention equipment storage box with a sound path and a sound horn formed in a position indicator lamp, and FIG. 26 is an explanatory diagram showing a central cross section of the position indicator lamp in FIG. 25.

[0136] This embodiment is characterized in that it combines the structure in which the sound path 72 is formed behind the position indicator lamp 14 shown in the embodiments of FIGS. 21 and 22 and the structure in which the sound holes 16 and the sound horn 80 are provided in the position indicator lamp 14 shown in the embodiments of FIGS. 23 and 24.

[0137] As shown in FIG. 25, in the disaster prevention equipment storage box 10 of this embodiment, the transmitter 12 is arranged below the exposed surface of the cover plate 10a, and the rectangular position indicator lamp 14 is arranged above it. A rectangular sound hole 16 is formed in the center of the position indicator lamp 14, and a sound horn 80 that opens in a conical shape centered on the sound hole 16 is formed.

[0138] That is, as shown in FIG. 26, the rectangular display frame 28n of the position indicator lamp 14 penetrates through the sound hole 16 that forms a rectangular hole in the protrusion 82 having a rectangular cross section formed behind the center. The front side of the sound hole 16 gradually expands in a conical shape, thereby forming the sound horn 80 on the front surface of the rectangular display frame 28n.

[0139] Also, as shown in FIG. 26, the rectangular display frame 28n of the position indicator lamp 14 is fixed to the front surface of the cover plate 10a by a screw 26 via a spacer 78 such that the protrusion 82 is positioned with a gap between the cover plate 10a and the exposed surface thereof within the mounting hole 75 formed in the cover plate 10a. As a result, an acoustic path 72 leading to the outside from the gap of the mounting hole 75 is formed between the cover plate 10a and the rectangular display frame 28n.

[0140] 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 at a position corresponding to the light-transmitting hole 70 of the cover plate 10a on the circuit board 34. Further, a rectangular opening 34a is formed in the circuit board 34, and the protrusion 82 formed behind the rectangular display frame 28n is positioned with a gap within the rectangular opening 34a.

[0141] 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 using a diffusing light-transmitting member through the light-transmitting hole 70, causing the entire surface of the position indicator lamp 14 to emit surface light in a substantially uniform red color.

[0142] Also, the sound from the acoustic device 24 disposed in 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 acoustic path 72 formed behind the rectangular display frame 28n from the gap of the rectangular opening 34a of the circuit board 34 and the gap of the mounting hole 75 of the cover plate 10a, and is output to the outside along the path indicated by the arrow 76.

[0143] In this way, in this embodiment, by forming the acoustic hole 16 and the acoustic horn 80 in the position indicator lamp 14 and forming the acoustic path 72 behind the position indicator lamp 14, in addition to reducing the installation space, the sound from the acoustic device 24 can be efficiently output to the outside, and the design can be greatly improved by forming the acoustic horn 80.

[0144] Note that the shape and arrangement of the acoustic horn 80 formed in the position indicator light 14 and the acoustic path 72 in the present embodiment, and the shape and arrangement of the acoustic path 72 formed behind the position indicator light 14 are merely examples and are not limited thereto. Appropriate shapes and arrangements may be used. Further, as shown in FIGS. 12 and 13, it may be provided in the fire hydrant device 50. The protrusion 82 may also have other shapes.

[0147] As shown in FIG. 28, the rectangular display frame 28p of the position indicator light 14 has a protrusion 77 formed in a rectangular cross section and extending in a conical shape behind the front rectangular frame, and an acoustic path 76 is formed in a direction that spreads conically from the back surface to the front surface. As shown in FIG. 27, acoustic holes 16 are formed in a frame-like shape divided into left, right, up, and down on the surface of the rectangular display frame 28p.

[0148] 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 located at the center of the mounting hole 75 formed in the cover plate 10a.

[0149] An LED storage portion 74 is formed in the protrusion 77 formed behind the rectangular display frame 28p, and an LED 32 is provided on the circuit board 34 arranged behind. An opening 34b is formed in the circuit board 34 arranged behind the protrusion 77, and the acoustic path 72 opens behind it. The opening 34b constitutes the acoustic hole.

[0150] Further, a light-transmitting hole 70 is provided at a position on the back side of the cover plate 10a where it stays behind the rectangular display frame 28p. Another circuit board 34 is disposed on the back side of the cover plate 10a, and an LED 32 is disposed at a position corresponding to the light-transmitting hole 70 of the cover plate 10a on this circuit board 34.

[0151] By driving the LED 32 arranged in this way to emit light, the light from the LED 32 enters the rectangular display frame 28p using the diffusing light-transmitting member, and the entire surface of the position indicator lamp 14 emits surface light in red substantially uniformly.

[0152] The 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 holes 16 opened on the front surface of the rectangular display frame 28p.

[0153] In this way, in this embodiment, by forming the acoustic path 72 inside the position indicator lamp 14, a path for sound is secured, and sound can be output and diffused efficiently. Further, the acoustic holes 16 are opened in a frame shape divided into four places in the rectangular display frame 28p of the position indicator lamp 14, so that new designability is obtained and the designability can be greatly improved.

[0154] Note that the arrangement of the acoustic path 72 and the LED 32 formed inside the position indicator lamp 14 in this embodiment is an example and is not limited thereto, and an appropriate arrangement may be used. Further, as shown in FIGS. 12 and 13, this embodiment may be provided in the fire hydrant device 50. Further, the display frame may be other than rectangular, for example, circular. Of course, the protruding portion may also have other shapes.

[0155] Further, the display lamp provided with the acoustic path in this embodiment may be arranged so that an acoustic path can be formed between the cover plate as in the embodiments of FIGS. 25 and 26.

[0156] [Embodiment of a disaster prevention equipment storage box with the display surface of the display lamp arranged on the front and side surfaces: Fifth invention] FIG. 29 is an explanatory diagram showing an embodiment of a disaster prevention equipment storage box in which a position indicator lamp and an acoustic hole area are intensively arranged in one place, and the display surface of the indicator lamp is provided on the front and side surfaces. FIG. 29(A) shows the front view, and FIG. 29(B) shows the side view.

[0157] As shown in FIG. 29, the storage case of the disaster prevention equipment storage box 10 of this embodiment is composed of a cover plate 10a and a main body 10b, and is installed on a wall surface or the like so that the cover plate 10a is exposed.

[0158] On the front surface 13a of the cover plate 10a exposed when the disaster prevention equipment storage box 10 is installed on a wall surface or the like, a transmitter 12 is arranged, and adjacent to the transmitter 12, a position indicator lamp 14 and an acoustic hole area 16a (area surrounded by the two-dot chain line in the figure) with an acoustic hole 16 opened are intensively arranged.

[0159] The transmitter 12 is provided with a protection plate 18 made of a transparent acrylic plate or the like for turning on the built-in push button switch 20 at the lower center thereof, and a maintenance door 22 with a telephone jack arranged inside at the upper part thereof.

[0160] Generally, the disaster prevention equipment storage box 10 is installed on a wall surface or the like with the arranged direction of the intensively arranged position indicator lamp 14 and acoustic hole area 16a and the transmitter 12 as the vertical direction. For example, the position indicator lamp 14 side is on the upper side (ceiling side), and the transmitter 12 side is on the lower side (floor surface side).

[0161] The position indicator lamp 14 has a substantially gate-shaped display frame 28q extending from the upper part of the front surface 13a of the cover plate 10a to the left and right side surfaces 13b. Thus, the position indicator lamp 14 has a display surface 15 on the front surface 13a and the side surfaces 13b of the storage case in the installed state of the disaster prevention equipment storage box 10.

[0162] Also, on the front surface 13a, the area surrounded by the display frame 28q of the position indicator lamp 14 on the upper side and the left and right sides becomes an acoustic hole area 16a provided with an acoustic hole 16. Thus, the position indicator lamp 14 and the acoustic hole area 16 are provided intensively in one place.

[0163] Thus, in this embodiment, by aggregating and providing the display frame 28q of the substantially gate-shaped position indicator lamp 14 surrounding the acoustic hole region 16a at one location, the dimensions in the arrangement direction of the aggregated and arranged position indicator lamp 14 and acoustic hole region 16a and the transmitter 12 are reduced, and the disaster prevention equipment storage box 10 can be miniaturized.

[0164] In addition, the visibility from the front in the installation state of the disaster prevention equipment storage box 10 is maintained by the display surface 15 on the front surface 13a provided on the position indicator lamp 14. At the same time, the visibility from the side is improved by the display surface 15 on the side surface 13b, and the visibility of the entire display lamp can be improved. Moreover, a new design property can be obtained, and the design property can be enhanced.

[0165] In this embodiment, a display surface is also provided on the upper surface of the storage case. 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 through from above, the visibility from above can also be ensured.

[0166] FIG. 30 is an explanatory diagram showing the exploded structure of the disaster prevention equipment storage box of FIG. 29. As shown in FIG. 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. An acoustic device 24 such as a buzzer or a bell is arranged at a position in the main body 10b opposite to the back of the acoustic hole region 16a formed in the cover plate 10a. When the acoustic device 24 is sounded by a district acoustic signal from a separately installed fire receiver, the fire alarm sound is output from the acoustic hole 16 shown in FIG. 29(A).

[0167] A corresponding recess 17 is formed at the transmitter arrangement position on the front surface 13a of the cover plate 10a, and the transmitter 12 is incorporated in the corresponding recess 17. The front top 12a of the transmitter 12 protrudes about several millimeters from the front surface 13a of the cover plate 10a.

[0168] In this embodiment, the display frame 28q is in the shape of a gate and surrounds the upper side and the left and right sides of the periphery of the acoustic hole region 16a, but it may also surround the lower side.

[0169] FIG. 31 is an explanatory diagram showing another embodiment of a disaster prevention equipment storage box provided with display surfaces of indicator lights surrounding a part of the acoustic hole area in a gate shape on the front and side surfaces. FIG. 31(A) shows the front view, and FIG. 31(B) shows the side view.

[0170] The disaster prevention equipment storage box 10 of the present embodiment shown in FIG. 31 is characterized in that, in addition to the embodiment of FIG. 29, an acoustic hole 16 (indicator light side acoustic hole) communicating with the acoustic hole 16 (cover plate side acoustic hole) of the cover plate 10 is provided in the display frame 28q of the position indicator light 14 to form an acoustic hole area 16b, and the rest is the same as the embodiment of FIG. 29.

[0171] Here, since both the acoustic hole area 16a and the acoustic hole area 16b constitute the overall acoustic hole area, in the present embodiment, the position indicator light 14 and a part of the acoustic hole area (acoustic hole area 16b) are arranged overlappingly.

[0172] Note that the indicator light side acoustic hole also corresponds to an opening, and a plurality of cover plate side acoustic holes may be arranged for one opening.

[0173] 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.

[0174] Also, in the present embodiment, the display frame 28q is in a gate shape and surrounds the upper side and left and right sides of the acoustic hole area 16a, but the lower side of the display frame 28q may also be surrounded. Further, on top of that, a part of the acoustic area 16a may be arranged 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.

[0175] FIG. 33 is an explanatory diagram showing an embodiment of a disaster prevention equipment storage box in which a display frame of a position indicator lamp is arranged sandwiching an acoustic hole area from both left and right sides, and display surfaces are provided on the front surface and side surface of the storage case. As shown in FIG. 33, the area display lamp 14 of this embodiment separates the display frame 28r into left and right parts, and is arranged so as to sandwich an acoustic hole area 16a having an acoustic hole 16 arranged on the front surface 13a of the cover plate 10a from both sides. As a result, the position indicator lamp 14 and the acoustic hole area 16a are provided in a concentrated manner at one location.

[0176] In addition, the display frames 28r arranged on both sides of the acoustic hole area 16a will have display surfaces 15 on the front surface 13a and side surface 13b of the storage case of the disaster prevention equipment storage box 10. Otherwise, it is the same as the embodiment of FIG. 29.

[0177] By thus concentrating and providing the display frame 28r of the position indicator lamp 14 so as to sandwich the acoustic hole area 16a from both left and right sides at one location, the dimensions in the arrangement direction of the concentrated position indicator lamp 14, the acoustic hole area 16a, and the transmitter 12 are reduced, and the disaster prevention equipment storage box 10 can be miniaturized.

[0178] Also, in the installed state of the disaster prevention equipment storage box 10, the 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 lamp 14. At the same time, the visibility from the side is improved by the display surface 15 on the side part 13b of the display frame 28r, the visibility of the entire display lamp can be improved, and a new design property can be obtained, thereby enhancing the design property.

[0179] Note that also in this embodiment, a display surface is provided on the upper surface of the storage case. 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 through from above, the visibility from above can also be ensured.

[0180] In addition, regarding the size relationship between the front display width W1 and the side display width W2 of the display frames 28r separately arranged on both the left and right sides of the cover plate 10a, the front display width W1 and the side display width W2 may be the same. For example, if it is desired to ensure visibility from the front, the front display width W1 may be made larger than the side display width W2. If it is desired to ensure visibility from the side, the side display width W2 may be made larger than the front display width W1. The front display width W1 and the side display width W2 may have any size relationship without being restricted. This also applies to the relationship between the front (the left and right parts of the gate shape) and the side display widths of the display frame 28q shown in FIG. 29, and the relationship between the front (the upper part of the gate shape) and the upper display width of the display frame 28q.

[0181] [Embodiment of a disaster prevention equipment storage box with display surfaces of display lights arranged on the front and side surfaces: Sixth invention] FIG. 34 is an explanatory diagram showing an embodiment of a disaster prevention equipment storage box in which a transmitter, a position display light, and an acoustic hole area are intensively arranged in one place, and the display frame of the display light is arranged so as to have display surfaces on the front, left and right side surfaces, upper surface, and lower surface of the storage case. FIG. 34(A) shows the front, FIG. 34(B) shows the side, and FIG. 34(C) shows the plan view.

[0182] As shown in FIG. 34, the storage case of the disaster prevention equipment storage box 10 of the present embodiment is composed of a cover plate 10a and a box-shaped main body 10b. The transmitter arranged 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. The transmitter main body 12b is arranged 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 arranged at the central part of the front surface 13a of the cover plate 10a.

[0183] The exposure height of the exposed parts of the push button switch 20 and the maintenance door 22, for example, the height of the top of the push button switch 20 and the maintenance door 22, is set to be equal to or less than the exposure height of the display surface on the side of the front surface 13a of the position display light 14. Note that the front surface 13a, the display surface on the front side, and the exposed tops of the push button switch 20 and the maintenance door 22 may be flush. Of course, as shown in FIG. 33, the two side surfaces 13b and the display surfaces on the sides, and the upper and lower surfaces and the upper and lower display surfaces can also be flush with each other.

[0184] The push-button switch 20 has a protection plate 18 and a switch button arranged inside a rectangular switch cover, and is connected to the transmitter main body 12b by a signal line. Also, a telephone jack is arranged inside the maintenance door 22 and is connected to the transmitter main body 12b by a signal line.

[0185] The position indicator lamp 14 has a display frame 28s that surrounds the push-button switch 20 of the transmitter and the periphery of the maintenance door 22, which are exposed on the front surface 13a of the cover plate 10a, in a rectangular shape and reaches both left and right side surfaces 13b of the cover plate 10a. As a result, the position indicator lamp 14 has a display surface 15 on the front surface 13a and the side surfaces 13b of the housing case of the disaster prevention equipment housing box 10.

[0186] Also, in the present embodiment, the display frame 28a also has a display surface 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 lamp 14 in the present embodiment is formed over the entire circumference of the front peripheral edge and the upper, lower, left, and right surface peripheral edges of the cover plate 10a.

[0187] In the portion of the display frame 28s of the position indicator lamp 14 that surrounds the push-button switch 20 arranged at the center of the front surface 13a of the cover plate 10a and the maintenance door 22, an acoustic hole region 16a having acoustic holes 16 divided into, for example, four locations of up, down, left, and right is provided.

[0188] Behind the portion of the front surface 13a of the cover plate 10a excluding the acoustic hole region 16a of the display frame 28s, LEDs 32 are appropriately arranged as shown by dotted lines, and the entire surface of the display frame 28s including the front surface 13a, the left and right side surfaces 13b, the upper surface 13c, and the lower surface 13d is made to emit surface light in a substantially uniform red color by the backlight illumination of the display frame 28s.

[0189] Here, the push-button switch 20 and the maintenance door 22 separated from the transmitter main body 12b require a smaller arrangement space compared to, for example, the transmitter 12 having the push-button switch 20 and the maintenance door 22 integrated as shown in FIG. 29. That is, for example, the front opening of the display frame 28s can be made smaller than the outer circumference of the built-in transmitter main body 12b.

[0190] In this way, the disaster prevention equipment storage box 10 of the present embodiment has the position indicator lamp 14 having the display frame 28s formed over the entire circumference of the cover plate 10a, the acoustic hole region 16a provided overlapping the display frame 28s, and the push-button switch 20 and the maintenance door 22 separated from the transmitter main body 12 integrated in one place. As a result, the size of the disaster prevention equipment storage box 10 can be significantly reduced compared to the embodiment of FIG. 29.

[0191] Also, the acoustic hole region 16a is arranged overlapping the display frame 28s of the position indicator lamp 14. Since the display frame 28s is not restricted by the acoustic hole region 16a in terms of its arrangement, the degree of freedom regarding the shape and arrangement of the display frame 28s can be increased. Note that the display lamp side acoustic hole also corresponds to an opening, and a plurality of cover plate side acoustic holes may be arranged for one opening.

[0192] Also, in the installed state of the disaster prevention equipment storage box 10, the visibility from the front is maintained by the display surface 15 of the front surface 13a of the display frame 28s provided on the position indicator lamp 14. At the same time, the visibility from the side is improved by the display surfaces 15 of the side surfaces 13b on both the left and right sides of the display frame 28s, improving the visibility of the entire display lamp, obtaining a new design, and enhancing the design.

[0193] Also, in an installation environment where the user can view the disaster prevention equipment storage box 10 from above and / or below when it is installed on a wall surface or the like, the visibility from above and below is improved by the display surfaces 15 of the upper surface 13c and the lower surface 13d of the display frame 28s provided on the position indicator lamp 28, improving the visibility of the entire display lamp.

[0194] Furthermore, the presence of the push-button switch 20 separated from the transmitter main body 12b is more clearly and easily recognizable due to the display frame 28s disposed to surround the periphery of the push-button switch 20, so that the position of the push-button switch 20 of the transmitter becomes easy to understand, and the user can operate the push-button switch 20 of the transmitter without getting lost. This also applies to the maintenance door 22 disposed separately from the transmitter main body 12b. During inspection or the like, the person in charge can open the maintenance door 22 without getting lost and insert the plug of the telephone carried therein into the telephone jack to make a call connection.

[0195] Note that the display frame 28s of the position indicator lamp 14 disposed on the front surface of the cover plate 10a is disposed to surround the periphery of the push-button switch 20 and the maintenance door 22 separated and disposed from the transmitter main body 12b in a rectangular shape, but it is not limited thereto. For example, it may be disposed to surround in a circular or elliptical shape. Also, for example, similar to surrounding a part of the periphery of the acoustic hole region shown in FIGS. 29 and 31, it may be a display frame that surrounds a part of the periphery of the exposed portion of the transmitter, such as in a portal shape. Further, for example, as shown in FIG. 35, the display frame 28s may be divided and disposed, or an appropriate shape arrangement such as providing the display frame at the four corners in a front view of the housing case may be selected.

[0196] As another structure of the acoustic hole region 16a provided with the acoustic hole 16 in the display frame 28s of the position indicator lamp 14, an opening serving as the acoustic hole region 16a may be formed in the display frame 28s, and the acoustic hole 16 may be formed in a portion of the front surface 13a of the cover plate 10a located within this opening.

[0197] Also, the joint between the front surface 13a and the side surface 13b of the cover plate 10a in the present embodiment is in an R-surface shape as shown in, for example, the plan view of FIG. 34(C), but it is not limited thereto. For example, it may be in a C-surface shape (chamfered shape), and the display surface 15 of the side surface 13b of the cover plate 10a may be formed to follow these shapes. This also applies to the joints between the front surface 13a and the upper surface 13c and the lower surface 13d of the cover plate 10a.

[0198] [Embodiment of a disaster prevention equipment storage box with sound holes provided on the side of the storage case: Seventh Invention] FIG. 36 shows an embodiment of a disaster prevention equipment storage box with sound holes provided on the side of the storage case. FIG. 36(A) shows the front view, and FIG. 36(B) shows the side view. The disaster prevention equipment storage box 10 is usually installed with the direction of the arrow shown in FIG. 36(A) facing upward. In this embodiment, on the front surface of the cover plate 10a, similar to the embodiment of FIG. 34, a push-button switch 20 provided with a protection plate 18 separated from the transmitter body and a maintenance door 22 are arranged. The transmitter arrangement area 12c (the area range seen from the front of the entire arrangement range of the transmitter including the transmitter body built in the storage case) where the push-button switch 20 and the maintenance door 22 are arranged is sandwiched from both sides, and display frames 28t of the position indicator lights 14 are arranged separately on the left and right sides of the front surface of the cover plate 10a. Along the inner side (the side where the push-button switch 20 and the maintenance door 22 are arranged) of this display frame 28t, a sound hole area 16a provided with a plurality of sound holes 16 is arranged. Also, the display frame 28t has a display surface on the side surfaces of the left and right sides of the cover plate 10a, and a sound hole area 16a provided with a plurality of sound holes 16 is arranged on the main body 10b along this display frame 28t. Here, the disaster prevention equipment storage box 10 of this embodiment has an arrangement overlapping portion 90 where the sound hole area 16a, the transmitter arrangement area 12c, and the position indicator light 14 overlap in the vertical direction.

[0199] In addition, a sound hole area 16a is also arranged on the side surface of the cover plate 10a along the display frame 28t.

[0200] By arranging the sound hole area 16a provided with the sound holes 16 on the side surface of the storage case in this way, the space on the front surface of the storage case is reduced, and further miniaturization of the disaster prevention equipment storage box 10 becomes possible.

[0201] Also, since the sound hole area 16a, the transmitter arrangement area 12c, and the display frame 28t of the position indicator light 14 are arranged such that their arrangement positions at least partially overlap in the vertical direction (perpendicular direction) in the installed state, the constraints on the space for arranging the sound holes 16, the transmitter area 12c, and the position indicator light 14 are relaxed, and the design freedom can be improved.

[0202] In addition, as shown in Fig. 36(C), a display surface of the display lamp 14 can be provided on the upper surface of the housing case of the disaster prevention equipment housing box 10, and the same applies to the lower surface.

[0203] Fig. 37 shows another embodiment of the disaster prevention equipment housing box with the sound holes provided on the side surface of the housing case. An acoustic hole region 16 (a cover plate side acoustic hole and a display lamp side acoustic hole) having a plurality of acoustic holes 16 overlapping with display frames 28t separately arranged on the left and right sides of the front surface of the cover plate 10a is arranged. Similarly, an acoustic hole region 16a having a plurality of acoustic holes 16 overlapping with the display frames 28t arranged on the left and right side surfaces of the cover plate 10a is arranged. Also in this case, there is an arrangement overlapping portion 90 as in the embodiment of Fig. 36.

[0204] Here too, as shown in Fig. 37(C), a display surface of the display lamp 14 can be provided on the upper surface of the housing case of the disaster prevention equipment housing box 10, and the same applies to the lower surface.

[0205] Fig. 38 is an explanatory diagram showing an embodiment of the disaster prevention equipment housing box with the display surfaces of the display lamps provided on the front surface and the side surface with the acoustic hole regions arranged sandwiching from the left and right, and is characterized by combining Fig. 36 and Fig. 37.

[0206] Note that although Figs. 36 to 38 show the acoustic holes provided on the side surface of the housing case, they may be similarly provided on the upper and lower surfaces of the housing case. Also, in Figs. 36 to 38, the acoustic holes are not provided on the front surface of the housing case, and they may be provided on the side surface or the upper and lower surfaces of the housing case.

[0207] Also, the front display width and the side display width of the display frames 28t separately arranged on the left and right sides of the housing case are not restricted from having an arbitrary magnitude relationship, similar to the embodiment of Fig. 33.

[0208] Incidentally, it does not prevent the installation of the disaster prevention equipment storage boxes in FIGS. 35 to 38 with the top and bottom reversed. Not limited to this, for example, the disaster prevention equipment storage box 10 in FIGS. 38 to 38 can also be installed horizontally. In this case, the left and right (horizontal) directions in each figure become the up and down (vertical) directions in the installation state, and the arrangement overlapping portion 90 is formed along the left and right (horizontal) directions in the installation state. Needless to say, when installed horizontally, the display surfaces above and below the illustrated storage case become the display surfaces on the left and right sides in the installation state, and the display surfaces on the left and right sides of the illustrated storage case become the display surfaces above and below in the installation state.

[0209] In addition, in the embodiments of the disaster prevention device in which the acoustic hole region, the transmitter arrangement region, and the indicator lights in FIGS. 36 to 38 are arranged such that at least a part of their arrangement positions overlap in the installation state, the embodiments of the disaster prevention device shown in FIGS. 11, 13, 18, 34, and 35 are also included.

[0210] [Modification Example of the Present Invention] In the embodiments of FIGS. 29 to 38, the display surface on the side of the display frame may extend to the main body side of the storage case. Also, it 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.

[0211] In addition, in the embodiments of FIGS. 29 to 38, the display surfaces on the left and right side surfaces may be provided only on one side that requires improved visibility from the side. The same applies to the display surfaces on the upper and lower surfaces.

[0212] In addition, a part of the storage case in each embodiment may be installed by being embedded in the wall surface. In the embodiments of FIGS. 29 to 34, at least a part of the display surface on the side surface of the storage case may be exposed from the wall surface. For example, as described in the embodiment of FIG. 29, the cover plate provided with the display frame can be exposed from the wall surface, and the main body can be embedded in the wall surface.

[0213] The configuration in which the position indicator light and the acoustic hole region in the above embodiment are intensively arranged in one place can be applied to the configuration in which the display unit and the acoustic output unit provided in the fire alarm receiver are intensively arranged in one place.

[0214] In addition, the above-described embodiment of the disaster prevention equipment storage box takes as an example the case where the acoustic hole, the position indicator lamp arranged at one place, and the transmitter are arranged vertically side by side. However, they may be arranged horizontally within the scope that conforms to the object of the present invention.

[0215] In addition, in the above-described embodiment, a diffusion and light-transmitting member is used for the display frame of the position indicator lamp. However, for example, an appropriate light guide member may be used. As an example, the light guide member has, for example, reflection dots printed on the back surface of a light guide plate made of acrylic. The light incident from the edge of the light guide plate is guided to the entire surface of the acrylic using the total internal reflection of the acrylic, and the light hitting the reflection dots changes its traveling path, and the light that has become an angle smaller than the total internal reflection angle exits from the front surface of the acrylic. By utilizing this, a light guide plate that causes the entire surface to glow uniformly red can be adopted. In addition, known lighting, light guiding, light transmitting, and light diffusing methods can be applied.

[0216] In addition, the present invention can also be applied to disaster prevention devices other than the equipment storage box and the fire hydrant device.

[0217] In addition, the indicator lamp may be, for example, an indicator lamp that indicates an abnormality such as a fire or other indicator lamps in addition to the position indicator lamp.

[0218] In addition, the present invention can also be applied to a disaster prevention device that does not include a transmitter when the indicator lamp and the acoustic hole can be intensively arranged.

[0219] In addition, the present invention is not limited to the above-described embodiment, and includes appropriate modifications that do not impair its object and advantages. For example, the above-described embodiments may be appropriately combined, or other modifications may be applied.

[0220] In addition, in the above-described embodiment, the case where the entire display surface in the display frame of the indicator lamp is the display area (light emitting area) is taken as an example. However, a part of the display surface may be the display area.
