Description

The present invention relates to an emergency alarm device and a method of attaching a light-emitting display thereof, and more particularly to an emergency alarm device having an indicator light and a method of attaching a light-emitting display thereof.

BACKGROUND ART Conventionally, there is an emergency alarm device for notifying the outside that an emergency situation (particularly a crime, fire, etc.) has occurred (see, for example, Patent Document 1). The emergency alarm device includes a transmitter that is pressed in an emergency, an indicator light that indicates the location of the transmitter, and an audio device that uses sound to notify the outside that an emergency situation has occurred. The emergency alarm device operates independently or in conjunction with each other, and when the transmitter is operated, the sound device sounds.

The indicator light of the emergency alarm device is attached to the equipment cover located on the front side of the emergency alarm device. The equipment cover is provided with a substantially rectangular opening, and a board on which a light emitting diode (LED), which is the light source of the indicator light, is mounted is attached to the opening, and a board is mounted to the opening to close the opening. A generally conical globe is further attached to cover the substrate. This glove is attached so as to protrude from the equipment cover to ensure visibility of the indicator light.

Such emergency alarm devices are connected to a commercial power source, etc., and receive power from the commercial power source, etc., but due to the standards, they cannot receive power from the commercial power source due to a power outage, etc. Even in such cases, it is necessary to be able to start up for a certain period of time using a backup power source such as a storage battery.

On the other hand, there is an indicator light that indicates the location of the fire extinguisher's transmitter. In recent years, indicator lights that do not protrude or hardly protrude from the device cover have been developed as indicator lights for transmitters (for example, see Patent Document 2). These indicator lights are installed around the transmitter and emit light in a ring shape to ensure visibility, and do not protrude from the equipment cover to prevent collisions with objects or people. It has the advantage of being able to prevent damage caused by the cause (hereinafter, this indicator light will be referred to as a ring-type indicator light).

The test button 7 is provided to test whether the backup power supply can normally supply power during a power outage or the like. In this embodiment, when the test button 7 is pressed, the emergency alarm device 1 turns on the confirmation light 8 while the test button 7 is pressed, if it detects that the backup power supply is operating normally. When the test button 7 is turned on and it is detected that the operation of the backup power source is abnormal, the confirmation light 8 blinks while the test button 7 is pressed.

The device cover 3 is provided with a substantially rectangular operation opening 9 so that the test button 7 can be pressed from outside the housing 2 . Further, an indicator light 10 is attached to the equipment cover 3, and a substantially circular opening 11 (hereinafter referred to as indicator light opening 11) for attaching the indicator light 10 is provided. At the periphery of the indicator light opening 11 located on the back surface of the device cover 3, a bottomed screw-fitting portion 13 is provided with a screw hole 12 formed therein for attaching a ring light plate 15, which will be described later, to the device cover 3. At the same time, one or more locking receivers 14 are provided.

The indicator light 10 includes a ring light plate 15, a scattering plate 16, a diffusion plate 17, and a substrate 18. A plurality of light emitting diodes (LEDs) 19, which are examples of light emitting elements, are intermittently mounted on the substrate 18 so as to be arranged on the same circumference. In this embodiment, the substrate 18 has a substantially horseshoe shape so that the transmitter 5 can pass through it. Further, the LEDs 19 are side-view LEDs, and are mounted toward the outside of the substrate 18 so as to face the light-receiving section 27 of the diffuser plate 17, which will be described later. They are arranged at angle (approximately 90°) intervals. The diffusion plate 17 is provided as a diffusion section for diffusing the light from the LED 19 in a ring shape.

The scattering plate 16 is provided to further scatter the light that has been diffused in a ring shape by the diffusion plate 17, and to cause a light-emitting display section 21, which will be described later, to shine with substantially uniform brightness throughout. In this embodiment, the scattering plate 16 is placed on the front side of the diffusion plate 17 and on the back side of the light emitting display section 21, which will be described later, and is made of a milky white resin in which a scattering agent is dispersed. It is molded flat on both sides. Incidentally, the scattering plate 16 is provided mainly to improve the aesthetic appearance of the emergency alarm device 1, and can be omitted.

A non-transparent part 22 is located inside the display part 21, and an operation opening 23 is formed so as to be surrounded by the non-transparent part 22. In other words, the collar portion 20 is the indicator light 10 and is located closer to the outer edge than the light emitting display portion 20. The collar portion 20 is provided with a protruding screw insertion hole 24 for holding the indicator light 10 on the device cover 3, and a locking portion 25 provided to correspond to the locking receiving portion 14. There is. The operation opening 23 is provided to enable the transmitter 5 to be operated from the outside of the housing 2 .

The light emitting display section 21 is transparent or translucent, and is provided so as to cover the front of the diffusion plate 17, so that the light diffused by the diffusion plate 17 (in this embodiment, the light further scattered by the scattering plate 16) is disposed so as to cover the front of the diffusion plate 17. light) is transmitted through the ring, creating a ring-shaped glow. A diffusion section 10 is provided on the back surface side of the light emitting display section 21 so that it can be fitted therein with the scattering plate 16 interposed therebetween. Furthermore, the light-emitting display section 21 has an inclined surface that slopes inward and toward the rear, and by doing so, it is possible to distinguish the indicator light 10 (light-emitting display section 21) from a wider direction. Become.

In the present embodiment, the ring light plate 15 is entirely made of a transparent or translucent material, and leaves a small area around the operation opening 23 inward from the light emitting display section 21. The non-transparent portion 22 is formed by pasting a sticker made of a non-transparent material to the opaque portion 22 . Furthermore, the operation opening 23 is rounded. Therefore, the area around the operation opening 23 is illuminated together with the light-emitting display section 21, and this portion functions as the light-emitting display section 26. That is, in this embodiment, the light-emitting display sections are provided at two locations, one where the light-emitting display section 21 is provided so as to cover the front of the diffusion plate 17, and the other where the light-emitting display section 26 is provided as a transmitting section. This means that it is provided so as to cover the surrounding area of 5. Note that the operating opening 23 preferably has a tapered shape that slopes inward. By doing so, it becomes easier to operate the transmitter 5.

When attaching the ring light plate 15 having the light emitting display section 21 to the device cover 3, the ring light plate 15 is temporarily fixed by rotating the locking portion 25 to the locking receiving portion 14 of the device cover 3. Thereafter, a screw is screwed into the screw hole 12 through the screw insertion hole 24.

The diffuser plate 17 is provided as a diffuser for diffusing the light from the LEDs 19, has a plurality of light receivers 27 that receive the light from the LEDs 19, and has a reflective groove 28 formed on its back surface. The light receiving section 27 is formed with a light receiving guide section 29 and a deflecting section 30 that is continuous with the light receiving guide section 29 .

In this embodiment, the reflective grooves 28 are grooves of the same depth, and the grooves are formed in parallel at equal intervals in the circumferential direction. Although the shape of the groove can be selected as appropriate, for example, a substantially V-shaped groove is adopted. Furthermore, the direction in which the groove is formed can be selected as appropriate, and may be directed toward the center of the diffuser plate 17, or may be directed toward an eccentric position. Furthermore, all the grooves may not be oriented in the same direction.

In this embodiment, the light receiving guide section 29 uses a side view LED as the LED 19, and since the LED 19 is located inward from the diffusion plate 17, the light receiving guide section 29 is arranged in the inner diameter direction of the diffusion plate 17. However, it is also possible to provide the LED 19 further outward than the diffuser plate 17, and in that case, the light receiving guide portion 29 is provided to face the outer diameter direction of the diffuser plate 17. . Note that the direction in which the light receiving guide portions 29 are directed can be selected as appropriate, and each light receiving guide portion 29 may be directed in different directions.

The deflection unit 30 is formed to deflect the light from the LED 19 in the circumferential direction of the diffuser plate 17 and diffuse it in a ring shape. It is a notch provided at 17. In this embodiment, the deflection section 30 is provided as a substantially V-shaped notch so that the light from the LED 19 is deflected clockwise and counterclockwise, and thereby the two deflection surfaces 31 is formed.

Therefore, in the indicator light 10 of this embodiment, by diffusing the light of the LEDs 19 in a ring shape with the diffusion plate 17, it becomes possible to illuminate the light-emitting display section 21 with a small number of LEDs 19, thereby saving power. Even if the power supply from a commercial power source is cut off and operation is forced to use a standby power source, the emergency alarm device 1 can be maintained in a state where it can be activated for a specified period of time. .

A second embodiment of the present invention will be described based on FIGS. 1, 4, and 5. The difference between this embodiment and the second embodiment is that a substrate 18 is provided separately, and the light emitting element (LED 19) is not mounted on the substrate 18 but on the substrate (not shown) of the main body 4. . Configurations with the same reference numerals as those in the first embodiment are the same as those in the first embodiment, so description thereof will be omitted.

The indicator light 32 of this embodiment includes a ring light plate 15, a scattering plate 16, a diffusion plate 33, and a light guide 34. The light guide 34 is provided as a light guiding portion for guiding light from an LED (not shown) mounted on the substrate of the main body 4 to the diffusion plate 33. Note that the light guide 34 can also be provided integrally with the light receiving section 27 (light receiving guide section 29) of the diffusion plate 33.

The diffuser plate 33 is basically the same as the diffuser plate 17 of the first embodiment, but the light receiving guide part 29 of the light receiving part 27 is different from the one shown in FIG. , are provided so as to face the light guide 34 and face the back side. Further, the diffusion plate 33 is formed with a screw stopper 35 which is screwed into the screw insertion hole 24 of the ring lamp plate.

The front side of the diffusion plate 33 is formed so as to be inclined inward and toward the back side in accordance with the shape of the light emitting display section 21. By doing so, the light emitting display section 21 can be completely covered. This makes it possible to emit light with more uniform brightness.

Although the present invention has been described based on the above embodiments, the present invention is not limited to the above embodiments, and can be modified as appropriate without changing the gist of the invention.

(1) Although the above embodiment is an example in which the indicator light of the present invention is applied to the emergency alarm device 1, the indicator light of the present invention may be used as an indicator light of another transmitter, such as a transmitter of a fire extinguishing device. It is also possible to apply By doing so, it becomes possible to realize power saving in fire extinguishing equipment as well. In this case, the light-emitting display section is attached so as to surround the transmitter, and the transmitter is located near where the non-transparent section 22 is located.

(2) In the first embodiment, the front side of the diffuser plate 17 is formed flat, but it is also possible to provide a vertical piece 37 on the outer peripheral edge of the front side like the diffuser plate 36 (Fig. 6(a)). By doing so, it is possible to cause the light emitting display section 21 to emit light with more uniform brightness throughout. Further, like the diffusion plate 33, it is also possible to form the front side to match the shape of the light emitting display section 21 and to incline toward the inside and back side, and by doing so, the same effect can be obtained. It becomes possible to play.

(3) In the second embodiment, the front side of the diffuser plate 33 was formed so that the inner circumferential side was lower than the outer circumferential side in accordance with the shape of the light emitting display section 21. However, like the diffuser plate 17, the front side It is also possible to form it flat. Further, it is also possible to provide a vertical piece 37 on the outer peripheral edge of the front side like the diffuser plate 33, and by doing so, the same effect can be achieved.

(4) In the above embodiment, the deflection section 30 is provided as a complete cutout, but it can also be provided so that the front surfaces of the diffusion plates 17 and 33 remain. By doing so, it is possible to prevent the shape of the deflection section 30 from being seen through from the surface side of the light emitting display section 21, and it is possible to make the light emitting display section 21 illuminate more uniformly.

(5) In the above embodiment, the light receiving section 27 is provided with the substantially cylindrical light receiving guide section 29, but the shape of the light receiving guide section can be changed as appropriate. For example, like the light receiving guide section 39 of the diffuser plate 38, it is also possible to provide a substantially triangular prism shape that widens from the back side toward the front side (see FIG. 6(b)). By doing this, the light from the light emitting elements will appear dotted from the light emitting display section 21, especially when the light emitting elements are provided on the back side of the indicator light as in the second embodiment. This makes it possible to prevent this.

(6) In the above embodiment, both sides of the scattering plate 16 are formed flat, but a protrusion 41 may be provided on the back side like the scattering plate 40 (see FIG. 7). The convex portion 41 is provided at a position facing the light receiving portion 27 of the diffuser plates 17 and 33, and normally attenuates the light from the light receiving portion 27, which has the highest brightness, and its vicinity, thereby reducing the light emitting display portion. 21 can be illuminated with more uniform brightness.

(7) In the above embodiment, the reflective grooves 28 are formed to have a uniform depth and at equal intervals in the circumferential direction, but the intervals may be changed depending on the distance from the LED 19, and the depth and shallowness of the grooves may be changed. You can change it. By doing so, the light emitting display section 21 can emit light more uniformly. For example, the depth of the grooves can be made deeper or the intervals can be made closer as the distance from the LED 19 increases.

(8) In the above embodiment, the light diffused in a ring shape is made to shine with substantially uniform brightness, but the interval between the reflective grooves 28 in the direction in which you want to make the light shine strongly is set so that the light shines strongly in the horizontal or vertical direction. You may change it, or you may change the depth and shallowness of the groove. For example, if it is desired to make the light-emitting display section 21 shine strongly in the left-right direction, it is possible to narrow the interval between the reflective grooves 28 in the left-right direction in the installed state, or to increase the depth of the grooves.

(9) In the above embodiment, the deflection unit 30 is provided with two deflection surfaces 31 so that the entire diffuser plate 17 can be illuminated with substantially the same brightness as possible, but only one deflection surface is provided, and the clockwise or The light may be diffused in one direction counterclockwise. At this time, the other clockwise or counterclockwise surface that does not diffuse the light is approximately parallel to the direction of incidence of light from the light receiving guide parts 29, 39 to the deflecting part 30, for example, from the light receiving guide parts 29, 39 side. It is also possible to form it so that the inclination angle when viewed is approximately a right angle.

(10) In the above embodiment, the inclination angles of the two deflection surfaces 31 of the deflection section 30 when viewed from the light receiving guide sections 29 and 39 are formed to be approximately the same angle, but the inclination angle of the deflection surface 31 is It is also possible to form them at different angles.
