Description

The present invention relates to a transmitter that is attached to a disaster prevention equipment storage box, a wall surface, or the like and is operated in the event of a fire or the like to notify the occurrence of an abnormality, and a method of attaching the transmitter.

Conventionally, the transmitter of disaster prevention equipment is attached to the disaster prevention equipment storage box, fire hydrant box, wall surface, etc., a push button switch is provided on the main body side of the transmitter, and the push button switch is turned on by pushing the protective plate placed on the cover side. Then, a fire alarm signal is sent to the receiver to give an alarm. The fire hydrant box houses transmitters, position indicators, etc. as disaster prevention equipment, and the disaster prevention equipment storage box also has an acoustic hole on the front cover plate side and a bell on the main body side.

A red indicator light is used as the position indicator light, and it is always lit to indicate the position of the disaster prevention equipment storage box so that people around you can recognize the location of the transmitter in an emergency. When the receiver receives the fire notification signal from the transmitter and outputs a fire alarm, the disaster prevention equipment storage box sends a district acoustic signal to the transmitter, which rings the bell of the disaster prevention equipment storage box to give a fire alarm. Sound is output (Patent Document 1). Similarly, when a transmitter is attached to a fire hydrant box or a wall surface, it is installed as a set with a position indicator light for making the building user recognize the position of disaster prevention equipment such as the transmitter.

By the way, when such a transmitter or the like is installed, it is necessary to secure a space for installing each disaster prevention device as a set, but in recent years, in order to reduce this installation space, the storage box for the disaster prevention device is downsized. Therefore, it has been proposed to abolish the position indicator light and install the position indicator lamp integrally with the transmitter. As for a transmitter integrally provided with a position indicator light, a transmitter in which a position indicator light is arranged so as to surround the periphery of a push button switch provided in the transmitter has been proposed (Patent Document 2). In the position indicator lamp provided so as to surround the periphery of the push button switch, a plurality of LEDs are distributed and arranged, or a sheet-shaped light emitting member is arranged in front of the transmitter to emit light in a planar manner.

Japanese Unexamined Patent Publication No. 9-102085 Jikkenhei 5-66794 Gazette Japanese Unexamined Patent Publication No. 2011-165114 Japanese Unexamined Patent Publication No. 2001-256865 Japanese Unexamined Patent Publication No. 2009-301115 Japanese Unexamined Patent Publication No. 2007-257107 Japanese Unexamined Patent Publication No. 2011-165114

However, when a transmitter equipped with a position indicator lamp in which a sheet-shaped light emitting member is arranged in front of the transmitter so as to surround the periphery of such a conventional push button switch is attached to the disaster prevention equipment storage box, the sheet-shaped light emitting member emits light. Since the surface is flush with the cover plate surface of the equipment storage box, there is a problem that the visibility of the position indicator lamp is lowered when the disaster prevention equipment storage box is viewed from the side.

In order to solve this problem, it is sufficient to mount the transmitter so that the light emitting surface protrudes outward from the mounting surface of the disaster prevention equipment storage box, as in the case of the conventional position indicator lamp that is provided independently. As a result, the installation space for the disaster prevention equipment storage box will increase.

Further, by arranging the sheet-shaped light emitting member in front of the transmitter so as to surround the periphery of the push button switch, it is possible to maximize the display area as a position indicator lamp, but the light from the light source is incident. In order to uniformly emit light from a sheet-shaped light emitting member with a required brightness, for example, when an LED is used as a light source, it is necessary to distribute and arrange a large number of LEDs behind the sheet-shaped light emitting member. However, there is a problem that the cost increases and the power consumption increases.

In addition, some transmitters are provided with a telephone jack covered by a door. In this case, a sheet is provided so as to surround the telephone jack door on the surface of the transmitter and the protective plate of the push button switch. Since the shape-emitting member is arranged in front of the transmitter, the display area becomes smaller and the shape of the sheet-shaped light-emitting member becomes complicated, and there is a problem that the distribution arrangement of LEDs according to this becomes complicated.

The present invention is provided with a position indicator lamp having a display portion that does not impair visibility from the lateral direction, does not increase the installation space of the disaster prevention equipment storage box, and effectively utilizes the exposed surface of the transmitter surface cover. It is an object of the present invention to provide a transmitter and a method of mounting the transmitter.

(Transmitter)
The present invention is a transmitter,
A cover member that can incorporate the exposed surface corresponding to the mounting hole formed on the mounting surface to be mounted into the mounting hole from the back side of the mounting surface, and
The main body fixed in a predetermined position in the back side direction of the cover member,
Equipped with
The cover member is formed so as to have a continuous surface without a step from the front side of the mounting surface to the exposed surface when the cover member is incorporated in the mounting hole.
The main body is characterized in that, when the main body is fixed to the cover member and the cover member is incorporated into the mounting hole, a positioning piece having a preset position to abut on the back side of the mounting surface is formed.

(How to install the transmitter)
The present invention
A cover member having an exposed surface corresponding to a mounting hole formed on the mounting surface to be mounted, and a cover member.
The main body fixed in a predetermined position in the back side direction of the cover member,
It is a method of mounting a transmitter equipped with
When the cover member is incorporated into the mounting hole, the cover member is formed so as to have a continuous surface without a step from the front side of the mounting surface to the exposed surface.
When the main body is fixed to the cover member and the cover member is incorporated into the mounting hole, a positioning piece having a preset position for contacting the back side of the mounting surface is formed on the main body.
The exposed surface of the cover member is inserted into the mounting hole from the back side of the mounting surface until the positioning piece abuts on the back side of the mounting surface .

(Basic effect)
According to the transmitter of the present invention, as a position indicator lamp, a display portion is arranged in a ring shape on the outer peripheral side excluding the central portion of the cover exposed surface, and a light source is emitted from the back side of the display portion to form a ring-shaped display portion. Since the surface emission is made to be almost uniform, the display part of the position indicator is arranged in a ring shape on the outer peripheral side excluding the central part of the exposed cover surface, so that the push button switch provided in the central part of the exposed surface of the cover is protected. By making the display area that maximizes the free area of the exposed surface of the cover without interfering with the board or the like, it is possible to secure visibility with a sufficient light emitting area.

Further, since the ring-shaped display portion of the position indicator lamp is formed so as to have an inclined display surface or a curved display surface slightly protruding forward on the inner peripheral side with respect to the outer peripheral side, the inclined display surface or the curved display surface is formed. By emitting light, it is possible to improve visibility from the side, and by minimizing the amount of protrusion to the outside, it is possible to avoid an increase in the installation space for the disaster prevention equipment storage box.

(Effect of dividing the ring-shaped display part)
The ring-shaped display part is divided into one or more divided display parts, for example, two parts that are up and down when attached to the disaster prevention equipment storage box, two parts that are left and right, or four parts that are up, down, left, and right. Since the display parts are connected in a ring shape, it is possible to easily arrange the display parts so as to have a substantially ring shape, avoiding, for example, a portion provided with a drainage structure of the transmitter.

(Effects of diffuser and light source)
The ring-shaped display portion is a diffusing member, and the light source is such that a plurality of light emitting elements are arranged on the main body side behind the ring-shaped diffusing member so that the diffusing member is backlit to emit surface light. When an LED is used as an element, a plurality of LEDs may be arranged in the ring direction behind the diffuser member at predetermined intervals, and the plurality of LEDs should be arranged without interfering with the arrangement space of the push button switch or the telephone jack in the central portion. Is possible.

In addition, the light source reduces loss by introducing light from a plurality of light emitting elements arranged on the main body side into the light guide plate by a light guide member to emit light, and reduces the number of light emitting elements such as LEDs to be used. It can be reduced.

Further, a light emitting tape member in which a plurality of light emitting elements are arranged on a tape-shaped flexible printed substrate with the light emitting surface oriented in the lateral direction orthogonal to the tape longitudinal direction is formed in a cylindrical shape corresponding to the ring-shaped diffusion member. By arranging them in a simple structure, it is possible to easily incorporate a plurality of light emitting elements corresponding to the ring-shaped diffusion member with a simple structure.

The cover plate 10a on the front surface of the disaster prevention equipment storage box 10 is provided with the transmitter 12 colored in red according to the present invention, and an acoustic hole 14 is formed under the transmitter 12 and is stored in the box behind the acoustic hole 14. Sound devices such as bells and buzzers are stored in the main body plate (not shown).

The transmitter 12 is provided with a protective plate 22 using a transparent acrylic plate or the like for turning on the built-in push button switch in the center thereof, and a maintenance door 28 in which a telephone jack is arranged inside, and a ring-shaped display portion is provided around the transmitter 12. A position indicator lamp 30 is provided.

The transmitter 12 is incorporated from the inside into a mounting hole formed in the cover plate 10a on the front surface of the disaster prevention equipment storage box 10, and is mounted so that the mounting surface on the front side of the cover plate 10a and the surface of the transmitter 12 are substantially flush with each other. ing.

[Embodiment of transmitter]
(Transmitter configuration)
2A and 2B are explanatory views showing an embodiment of a transmitter provided in the disaster prevention equipment storage box of FIG. 1, showing the front side in FIG. 2A and the side surface in FIG. 2B. Further, FIG. 3 is a cross-sectional view showing the internal structure of the transmitter together with the state of attachment to the disaster prevention equipment storage box.

As shown in FIGS. 2 and 3, the transmitter 12 is composed of a cover member 16, a main body 18, and a back cover 20, and a mounting portion 20a of the back cover 20 fixed to the back of the main body 18 is attached to a disaster prevention device storage box 10. The cover member 16 is fixed to the main body plate 10b provided inside the cover plate 10b from the inside by screwing or the like, and the cover member 16 is incorporated into the mounting hole formed in the cover plate 10a of the equipment storage box from the inside, and the exposed surface of the cover member 16 is the surface of the cover plate 10a. I try to be almost flush. In addition, the mounting structure of the transmitter 12 to the disaster prevention equipment storage box 10 may be an appropriate structure.

The cover member 16 is fixed by fitting the fitting claw 16a to the main body 18. The main body 18 houses a circuit board 24 inside, and a push button switch 26 having a switch knob 26a and a plurality of LEDs 36 used as a light source of a position indicator lamp 30 are mounted on the circuit board 24. In the figure of the main body 18, positioning pieces 18a are formed at four locations on the upper outer side, and abut on the back surface of the cover plate 10a of the disaster prevention equipment storage box 10 to determine the mounting position.

The cover member 16 is provided with a position indicator lamp 30. The position indicator lamp 30 has a pair of display portions 32 arranged in a ring shape on the outer peripheral side excluding the central portion of the exposed surface (surface) of the cover member 16. That is, the display portion 32 is a divided display portion in which the ring is divided into two left and right.

A diffusion member that emits red light is used for the display portion 32. The diffusion member is a member that incidents light from a point light source such as an LED and converts it into surface emission. An LED storage portion 34 is formed behind the diffuser member serving as the display portion 32, and a plurality of LEDs 36 mounted on the circuit board 24 are arranged in a ring shape at predetermined intervals, and the diffuser member is diffused by the backlit illumination of the LED 32. The entire surface of the position indicator lamp 30 is made to emit red light substantially uniformly by incident on the display portion 32 used.

Further, the display surface of the display portion 32 is formed on an inclined display surface 32a whose inner peripheral side slightly protrudes forward with respect to the outer peripheral side, and when the position indicator lamp 30 is viewed from the side by the inclined display surface 32a. I am trying to improve the visibility of. The degree of inclination of the inclined display surface 32a may be set to an appropriate angle within a range in which the protrusion dimension from the surface of the cover plate 10a of the disaster prevention equipment storage box 10 does not exceed, for example, several millimeters. A curved display surface may be used instead of the inclined display surface 32a.

(Visibility of position indicator light)
The position indicator light 30 of the transmitter 12 shown in FIGS. 2 and 3 is constantly lit in a state where the device storage box 10 of FIG. 1 is embedded in the wall surface of the caution area, for example, and emits red light. The installation location of the machine 12 can be easily visually recognized even from a distance. In this case, the display portion 32 using the diffusion member of the position indicator lamp 30 is arranged as a ring-shaped member divided into left and right along the outer circumference of the cover member 16, and the light from the LED 36 is incident on the ring. When viewed from a distance, the entire exposed surface, which is the front surface of the transmitter 12, shines uniformly, and it looks like a surface emission with a sufficiently large area. It is possible to ensure the same or better visibility.

Further, since the display portion 32 forms an inclined display surface 32a slightly inclined to the outside, the inclined display surface 32a causes surface emission toward the oblique lateral direction, and when the transmitter 12 is viewed from the oblique lateral direction. It is possible to further secure sufficient visibility.

Further, the position indicator light 30 provided on the transmitter 12 is a cover plate of the disaster prevention equipment storage box as compared with the conventional dedicated position indicator lamp provided so as to protrude by several centimeters from the surface of the cover plate 10a of the disaster prevention equipment storage box. The amount of protrusion is so small that it is substantially flush with the surface of 10a, and even if the transmitter 12 equipped with the position indicator light 30 is attached to the disaster prevention equipment storage box, the installation space is not increased, and in particular. When the disaster prevention equipment storage box is embedded in the wall surface, the transmitter 12 provided with the position indicator light 30 does not pop out forward.

[Other embodiments using a light guide]
4A and 4B are explanatory views showing another embodiment of a transmitter using a light guide as a position indicator lamp, FIG. 4A shows the front side, and FIG. 4B shows the side surface.

As shown in FIG. 4, in this embodiment, the light guide 40 is arranged in the LED storage portion 34 behind the display portion 32 arranged in a ring shape on the cover member 16, and the light from the LED 36 is directed to the light guide 40. It is incident on the display portion 32 using the light guide member through the light guide member so that the entire surface is uniformly lit in red. The light guide 40 has a structure in which a reflective layer is formed on the outer periphery of a cylindrical transmissive member, for example, and the light from the LED 36 propagates in the axial direction with low loss without being diffused to the surroundings and is incident on the display portion 32. .. Further, as the light guide 40, one in which a plurality of optical fibers are bundled may be used.

By incident the light from the LED 36 on the display portion 32 using the diffusing member through the ride guide 40 in this way, the loss of the incident light amount can be reduced, and as a result, for example, the implementation of FIGS. 2 and 3. The number of LEDs 36 used can be reduced as compared with the form. Since the other configurations are the same as those of the embodiments of FIGS. 2 and 3, the description thereof will be omitted.

[Other Embodiments Using LED Tape as a Light Source]
5A and 5B are explanatory views showing another embodiment of the transmitter using the LED tape as the light source of the position indicator, FIG. 5A shows the front side, and FIG. 5B shows the side surface. 6 is an explanatory view showing the LED tape taken out, a plane is shown in FIG. 6A, and a side surface is shown in FIG. 6B.

As shown in FIGS. 5 and 6, in this embodiment, the LED tape 41 is used as the light source of the position indicator lamp 30 provided in the transmitter 12.

The LED tape 41 functions as a light emitting tape member, and as shown in FIG. 6, a plurality of LED chips 44 are mounted on a tape-shaped flexible printed circuit board (FPC) 42 at predetermined intervals. In the case of the present embodiment, the LED chips 44 are arranged at predetermined intervals on the outer upper portion of the tape-shaped flexible printed circuit board 42 (not shown). The LED chip 44 is a minute box-shaped chip, and a light emitting surface 46 is provided in the center upward in the drawing, electrodes 48 are provided on both sides thereof, and the electrodes 48 are soldered and fixed to a circuit pattern formed on a flexible printed substrate 42. There is. Further, in order to ensure waterproofness, the entire LED tape 41 may be coated with a transparent resin material. Further, the LED tape 41 is formed in a cylindrical shape corresponding to the display portion 32 using the ring-shaped light guide member shown in FIG.

As shown in FIG. 6, the LED tape 41 formed in a cylindrical shape is housed in the LED storage portion 34 of the main body 18, the flexible printed circuit board 42 is mounted on the circuit board 24 by soldering, and the LED chip 44 is on the upper side thereof. The light emitting surface 46 is arranged toward the display portion 32 using the diffusion member of the position indicator lamp 30 located at the upper part, and the light from the backlight illumination is incident so that the entire surface is uniformly illuminated in red.

By using such an LED tape 41 as a light source, a large number of LED chips can be arranged in a simple structure according to the ring-shaped display portion 32, and the cost can be reduced.

[Ring-shaped display area]
7 and 8 are explanatory views showing another embodiment of the ring-shaped position indicator lamp. FIG. 7 is an explanatory diagram showing an embodiment of a transmitter 12 provided with a position indicator lamp 30 having a ring-shaped display portion 32 separated at one lower location, because there is only one separated location. Therefore, the display area can be made larger than that of the embodiment shown in FIG. 2, and the visibility of the position indicator lamp 30 can be improved. It should be noted that the reason why the divided portion of the display portion 32 is on the lower side of the transmitter 12 is that a drainage structure (not shown) is provided inside the display portion 32 and the display portion 32 is inserted between the cover member 16 of the transmitter 12 and the main body 18. A drainage channel for draining water downward from the divided portion of the display portion 32 is formed.

FIG. 8 is an explanatory diagram showing another embodiment of the transmitter 12 provided with the position indicator lamp 30 having the display portion 32 divided into rings at four locations on the top, bottom, left, and right. Although the display area is reduced, the visibility of the position indicator lamp can be sufficiently ensured from the left-right direction of the transmitter 12. Sufficient visibility can be ensured by increasing the amount of light emitted from the LED. Further, by dividing the display portion 32 using the diffusion member into four parts, the size of each can be reduced, the deformation due to bending during manufacturing is reduced, and the cover member 16 is integrated by synthetic injection or mounting arrangement. It will be easy. Further, by dividing the display portion 32 into four parts and arranging them in a ring shape, it is possible to improve the appearance in terms of design.

In addition to this, the display portion 32 may be appropriately divided into two, three, and the like as necessary. Further, it may be formed into a complete ring shape without being divided. When the display portion has a perfect ring shape, a drainage structure is provided inside the display portion, so that the LED may be arranged while avoiding the drainage structure portion.

[Modified example of the present invention]
In the above embodiment, a transmitter used by attaching it to a disaster prevention equipment storage box is taken as an example, but a transmitter installed independently on a wall surface or the like or a transmitter installed on a fire hydrant device is also in the same position. The indicator light can be provided integrally.

Further, in the above embodiment, the diffusion member is used for the display portion of the position indicator lamp, but a light guide member may be used. For example, the light guide member has reflection dots printed on the back surface of the light guide plate made of acrylic, and the light incident from the edge of the light guide plate is guided to the entire surface of the acrylic by using the total reflection of the acrylic, and the light hitting the reflection dots is emitted. By changing the course and utilizing the fact that the light that is smaller than the total reflection angle comes out from the front surface of the acrylic, the entire surface of the light guide plate is made to shine uniformly in red.

Further, in the above embodiment, the ring-shaped display portion is formed so as to have an inclined display surface or a curved display surface slightly protruding outward from the inner peripheral side with respect to the outer peripheral side, but the present invention is limited to this. It may be a flat plate that does not protrude, and may have a shape that allows the general public to visually recognize the position of the transmitter from the diagonal side. For example, in a configuration as shown in FIG. 2, in which there are two display portions that continuously emit light in the vertical direction, sufficient visibility can be obtained from the left and right.

Further, the present invention is not limited to the above-described embodiment, includes appropriate modifications that do not impair its purpose and advantages, and is not further limited by the numerical values shown in the above-described embodiment.
