  However, in such a conventional disaster prevention device, a push button switch is arranged at the back of the central opening of the transmitter, and a transparent plate arranged in front of the push button switch is turned on until the push button switch is turned on. For example, the on operation is performed by pushing and moving in the depth direction by several centimeters. Since the push button switch in the transmitter includes a push button that can move forward and backward and a main body that houses a circuit behind, there is a problem that a space is required in the depth direction and the transmitter becomes large.

  In addition, since the red indicator lamp, transmitter and speaker were prepared as separate devices and assembled and arranged on the front of the device door, a large installation space was required, resulting in an increase in size of the device. There is also a high risk of damage to the design.

  Further, since the transmitter is arranged away from the red indicator lamp, there is a problem that the location of the transmitter is difficult to understand when there is smoke due to fire.

An object of this invention is to provide the disaster prevention apparatus which reduces the installation space of disaster prevention apparatuses, such as a transmitter, and improves the operativity of a transmitter.

  FIG. 1 is an explanatory view showing an equipment storage box equipped with a disaster prevention device according to the present invention, and FIG. 1 (A) shows a front view and FIG. 1 (B) shows a side view.

  In FIG. 1, an equipment storage box 10 includes a cover 10a and a main body 10b, and a disaster prevention device 12 according to the present invention is provided on the cover 10a. The disaster prevention device 12 has a transmitter 16 disposed at the center of a red indicator lamp 14 having a donut shape, and a speaker is used as an audio device behind the red indicator lamp 14 and the transmitter 16 as will be described later. Built-in. In the present embodiment, the red indicator lamp 14 and the speaker are built in the transmitter 16, and since they are integrated, the dimensions of the cover 10a and the main body 10b are smaller and lighter than the conventional one shown in FIG.

  FIG. 2 is an explanatory view showing, in section, an embodiment of the disaster prevention device according to the present invention. In FIG. 2, the disaster prevention device 12 is fitted and fixed in the mounting hole 15 of the cover 10a in the equipment storage box. In the disaster prevention device 12, a cylindrical main body 20 is disposed behind a disk-shaped mounting cover 18, and a waterproof cover 38 is attached to a small-diameter protruding portion at the rear of the main body 20.

  A red indicator lamp 14 is provided on the front surface of the mounting cover 18. The red indicator lamp 14 includes a diffusion dome cover 22 having a donut shape, and a plurality of LEDs 24 arranged on the mounting cover 18 in a ring shape along the donut shape of the diffusion dome cover 22. The diffusion dome cover 22 receives light from the light emission drive of the LED 24 disposed on the mounting cover 18 side and shines in red so that the installation location of the disaster prevention device 12 can be confirmed from a distance.

  In the present embodiment, the diffusion dome cover 22 having a dome-shaped cross section is used as a portion where the red indicator lamp 14 shines. However, a flat donut-shaped diffusion is provided without providing a dome-shaped protruding shape. It is good also as a cover. In such a donut-shaped diffusion cover, the red indicator lamp 14 can be clearly confirmed from a distance even if it is not a shape that projects forward like the diffusion dome cover 22 by sufficiently increasing its size. can do.

  Usually, as a function required for the red indicator lamp 14, a display function that can be sufficiently confirmed from a lateral direction of 15 degrees oblique to the mounting surface is required, and has a dome section as shown in the embodiment of FIG. Even if it is the diffusion dome cover 22 or the flat diffusion cover, the visibility of the red indicator lamp 14 from the oblique 15 degree direction can be ensured by sufficiently increasing the donut diameter.

  The transmitter 16 is disposed in the donut hole of the diffusion dome cover 22 constituting the red indicator lamp 14. In the transmitter 16, a pressure-sensitive switch 26 is disposed on the mounting cover 18, a push plate 28 for uniformly applying a pressing force to the pressure-sensitive switch 26 is disposed on the outside, and a protective film 30 is further disposed on the outside. Is arranged.

  The pressure sensitive switch 26 is a film-like (thin film-like) sensor whose resistance value changes according to the pressing force. The sensor constituting the pressure-sensitive switch 26 is composed of, for example, two upper and lower polyester films. A conductive layer is formed on each film layer, and a pressure-sensitive ink layer is formed thereon. The two film layers are laminated together with an adhesive to constitute a sensor.

  When the sensor constituting the pressure sensitive switch 26 receives a pressing force from the outside, the resistance value decreases. For example, the resistance value of the pressure-sensitive switch 26 is, for example, 10 MΩ when no load is applied with no pressing force, and when the pressing force is received from this state, the resistance value decreases, for example, 20 KΩ at the maximum load. It is desirable that the change in resistance value with respect to the change in pressing force has sufficiently high linearity.

  The resistance value of the pressure-sensitive switch 26 is converted into, for example, a voltage signal by a detection circuit that will be described later, and a pressure-sensitive detection signal (voltage signal) that increases linearly according to the pressing force can be obtained. When the comparator exceeds a predetermined threshold level, a transmission signal is output to the outside as a result of the operation of the pressure sensitive switch 26 being performed.

  A speaker 32 is disposed behind the mounting cover 18 as an acoustic device. The speaker 32 is disposed in the acoustic chamber 35 in the speaker storage portion 34 disposed on the back side of the mounting cover 18. The speaker housing portion 34 has a central portion facing the speaker 32 of the acoustic chamber 35 protruding in a conical cone shape toward the speaker 32, and a diffusion dome cover for the transmitter 16 and the red indicator lamp 14 in front of the acoustic chamber 35. A plurality of acoustic holes 36 are formed in the part of the mounting cover 18 between the two.

  A circuit storage unit 45 is formed behind the speaker storage unit 34, and a circuit unit 44 is incorporated therein. A plurality of signal lines 42 are connected to the terminal 40 of the circuit storage unit 45, and a transmission signal when the transmitter 16 is operated to the outside by the signal line 42 is output. If necessary, an acknowledgment signal is received from the outside after the transmission signal is output, and when the acknowledgment signal is received, the LED 24 of the red indicator lamp 14 is blinked or blinked to drive the red indicator lamp 14. The confirmation response display is enabled.

  FIG. 3 is an explanatory view showing the disaster prevention apparatus of FIG. 2 from the front. In FIG. 3, the disaster prevention device 12 according to the present invention is attached to the cover 10a of the equipment storage box toward the front. The disaster prevention device 12 includes a donut-shaped red indicator lamp 14 and a transmitter 16 disposed in the donut hole.

  The red indicator lamp 14 includes a donut-shaped diffusion dome cover 22 and a plurality of LEDs 24 arranged in an annular shape behind the donut-shaped diffusion dome cover 22. Sound holes 36 are formed at four locations in the gap between the transmitter 16 and the diffusion dome cover 22 in the red indicator lamp 14 so that an alarm sound from a speaker incorporated behind the transmitter 16 is emitted to the outside. Yes.

  FIG. 4 is a circuit block diagram showing an embodiment of a circuit unit provided in the disaster prevention apparatus of FIG. In FIG. 4, the circuit unit 44 includes a power supply unit 46 and a transmission unit 52. The power supply unit 46 is connected to the power supply line 42a, the transmission unit 52 is connected to the transmission line 42c, and the common line 42b is connected. Yes. Signal lines 42 d and 42 e are connected to the speaker 32.

Pressure sensitive switch 26 may be represented by a variable resistance Rs of change in the resistance value in response to the pressing force, applied predetermined power supply voltage Vi at one end, for example, a Vi = -5 volts, and the other end constitutes a comparison circuit The inverting input terminal of the operational amplifier 48 is connected. The operational amplifier 48 has a non-inverting input terminal connected to the ground and a resistor Rf connected to a feedback circuit connecting the inverting input terminal and the output terminal, and the value of the resistor Rs of the pressure-sensitive switch 26 is converted into a pressure-sensitive detection signal Vo that becomes an output voltage. Convert and output.

  Here, the following relationship exists between the resistance Rs of the pressure-sensitive switch 26 of the detection circuit constituted by the operational amplifier 48 and the output voltage Vo.

Vo = Vi (Rf / Rs) (1)
The pressure-sensitive detection signal Vo that is the output of the operational amplifier 48 is given to the inverting input terminal of the comparator 50 that constitutes the determination unit. A reference voltage source 51 is connected to the non-inverting input terminal of the comparator 50 to set a predetermined reference voltage Vr. When the pressure-sensitive detection signal Vo from the operational amplifier 48 exceeds the reference voltage Vr, the comparator 50 inverts the output from the previous L level to the H level, and in response to this, the transmission unit 52 is connected to the outside by the transmission line 42c. Output outgoing signal.

Further, the circuit unit 44 is provided with a light emission drive unit 54, and a plurality of LEDs 24 provided on the red indicator lamp 14 are connected in parallel to the light emission drive unit 54 as shown in FIG. In a normal state, the light emission drive circuit 54 supplies a drive voltage to the LED 24 to drive the light emission, thereby causing the diffusion dome cover 22 to shine, thereby displaying the red indicator lamp 14 in red.

  A transmission unit 52 is connected to the light emission drive unit 54. Based on the H level output of the comparator 50, the transmission unit 52 outputs a confirmation response signal to the light emission drive unit 54 when receiving a confirmation response signal from the outside after transmitting a transmission signal to the outside through the transmission line 42c. Then, the light emission drive unit 54 performs blinking or blinking of the LED 24, and displays a confirmation response to the transmission of the transmission signal by blinking or blinking of the red indicator lamp 14.

  In the circuit unit 44 of FIG. 4, when the confirmation response signal is received by the light emission drive unit 54, the confirmation response display is performed by the red indicator lamp 14 by blinking or blinking of the LED 24. The response display is not necessarily provided.

  Further, in the circuit unit 44 of FIG. 4, when the pressure-sensitive detection signal Vo from the operational amplifier 48 exceeds a predetermined reference voltage Vr by the comparator 50 constituting the determination unit, a transmission signal is output to the outside. However, a determination unit may be configured to send a transmission signal to the outside when the H level output of the comparator 50 continues for a predetermined time. Thus, when the state where the pressure-sensitive detection signal Vo is equal to or higher than the reference voltage Vr continues for a predetermined time, the operation of the pressure-sensitive switch 26 is determined and a transmission signal is output, so that the switch operation of the transmitter 16 due to mischief or the like is performed. Can be prevented.

  As described above, in the embodiment of the disaster prevention device 12 according to the present invention shown in FIGS. 2 to 4, since the red indicator lamp 14, the transmitter 16 and the speaker 32 are integrated, it is installed on the equipment storage box or the like. The space can be greatly reduced compared to the case where the conventional installation is divided into three parts, and the disaster prevention device 12 itself can be reduced in size and weight as well as in its installation location. The design can be greatly improved.

  Further, since the thin film pressure-sensitive switch 26 using a film sensor is used as the transmitter 16, even if it is integrated with the red indicator lamp 14, the depth dimension can be reduced and the thickness can be sufficiently reduced.

  In addition, since the display shape of the red indicator lamp 14 is a donut shape, and the transmitter 16 is disposed in the donut-shaped hole, the transmitter 16 is located in red even in the presence of smoke due to fire or the like. The donut-shaped display of the indicator lamp 14 makes it obvious, and high operability in an emergency such as a fire can be realized.

  Further, the switch operation of the pressure sensitive switch 26 provided in the transmitter 16 can arbitrarily determine the pressing force for determining the switch operation by setting the reference voltage Vr of the comparator 50 as the determination unit shown in FIG. In order to give an operational feeling that the transmitter 16 has been operated with certainty, it is possible to easily generate an operation force to be transmitted only after pressing with a certain degree of strength, and further, it is necessary to press with a certain degree of strength. It is possible to prevent mischievous operations.

  Moreover, in the conventional transmitter, when the push button is pressed once, the transparent plate arranged in front of the push button moves into the transmitter and does not return to the original state. Although the alarm is continued immediately and the recovery work takes time, in the above embodiment, if the pressure sensitive switch is not pressed for a predetermined time and / or a predetermined pressing force, it is not determined as a transmission operation, and an error due to mischief Calls can be prevented.

  Furthermore, since the display shape of the red indicator lamp 14 is a donut shape, it can be easily formed into a donut shape having a large diameter, and a red indicator lamp excellent in visibility and design can be realized.

  In the above embodiment, since the transmitter is a film-like sensor, the stroke distance of a button like a conventional push button can be eliminated, so the distance in the depth direction can be reduced, and the reduction thereof. By disposing acoustic alarm means such as a speaker in a space where the disaster can be made, the disaster prevention equipment storage box for storing the transmitter or the like can be reduced in size.

  In the above embodiment, the transmitter, the red indicator lamp, and the speaker are integrated. However, the present invention is not limited to this, and in the case of the structure of only the transmitter, the pressure transmitter is used to make the transmitter thinner. Can be achieved. Also, a combination of a transmitter and a red indicator lamp, or a combination of a transmitter and a speaker may be integrated, and in this case, the housing dimensions can be suppressed. The red indicator lamp for informing the position of the transmitter is provided separately from the transmitter as usual, and the red indicator lamp 14 integrated with the transmitter of the above embodiment is normally turned off and the transmission operation is performed. It may be made to function as a response indicator lamp that is lit or flashes when the call is made and informs the operator that the transmission operation has been performed.

  FIG. 5 is an explanatory view showing, in section, another embodiment of the disaster prevention device according to the present invention. In FIG. 5, in the present embodiment, the disaster prevention device 12 is disposed by a mounting member 56 in a mounting hole 72 provided in the cover 10 a. The red indicator lamp of the disaster prevention device 12 includes a frame member 64 having a donut shape made of a translucent rubber member, a light guide 74, and an LED 24.

  Although the frame member 64 is made of a rubber material, it has a function as a light guide that can further shine by entering light from behind, and in order to function as such a light guide, for example, A light-transmitting rubber such as silicon rubber may be used.

  A light guide 74 is disposed in a ring shape behind the frame member 64, and the LED 24 is disposed in a lower portion of the light guide 74.

  When the LED 24 is driven to emit light, the light enters the frame member 64 through the light guide 74, and the frame member 64 made of a light-transmitting rubber member is entirely illuminated in red to function as a red indicator lamp.

  Although the donut-shaped frame member 64 has a flat display surface, it may be a dome-shaped frame member 64a as shown by an imaginary line so as to improve the visibility from the lateral direction.

  In the transmitter, a protective plate 66 using an organic glass plate or the like is held by a frame member 64 with respect to the mounting hole 72, and the pressure sensitive switch 26 is separately arranged behind the protective plate 66.

  A speaker housing portion 62 is disposed inside the attachment member 56, the pressure sensitive switch 26 is disposed on the front surface of the speaker housing portion 62, and the speaker 32 is disposed in the acoustic chamber 63 behind the speaker housing portion 62. A plurality of acoustic holes 36 are formed in an annular shape around the pressure sensitive switch 26 arranged on the front surface of the speaker housing 62.

When operating the transmitter, if the protective plate 66 held by the frame member 64 is pressed hard, it is removed from the frame member 64 and pressed against the pressure sensitive switch 26 as shown by the protective plate 66a. It was added pressure, and transmits the oscillation signal to determine a switch operation when the sensitive pressure detection signal exceeds a reference value set in a predetermined duration and pressure to the outside.

  A circuit housing portion 58 is screwed and fixed to the rear portion of the attachment member 56, and a plurality of signal wires 42 connected to the terminals 40 of the circuit housing portion 58 are pulled out, and a waterproof cover 60 is attached to cover the circuit housing portion 58. doing. The circuit storage unit 58 stores the circuit unit 44, and the circuit unit 44 is the same as that shown in FIG.

  FIG. 6 is an exploded view showing the transmitter operation portion of FIG. In FIG. 6, a frame member 64 made of a translucent rubber material is attached to the mounting hole 72 of the cover 10a. The frame member 64 is a ring-shaped member having an operation hole 65 in the center, and is formed with four stopper portions 68 on the back side of the operation hole 65, and the inner periphery of the operation hole 65 corresponding to the stopper portion 68. A retaining portion 70 is formed in the portion. The protection plate 66 is sandwiched between the retaining portion 70 and the stopper portion 68 of the frame member 94 and is installed on the frame member 64.

  FIG. 7 is an explanatory view showing the frame member 64 extracted from FIG. 6, in which FIG. 7 (A) shows the front, FIG. 7 (B) shows the side, and FIG. 7 (C) shows the back.

  In FIG. 7, the frame member 64 is formed with an operation hole 65 having a diameter slightly larger than that of the protective plate 66 shown in FIG. 6, and is divided into four places behind the operation hole 65 so as to protrude to the center side. Are integrally formed. On the inner periphery of the operation hole 65 corresponding to the stopper portion 68, a retaining portion 70 is formed integrally with the stopper portion 68 so that the circumferential width and the protruding amount are reduced.

  FIG. 8 is a cross-sectional view showing the XX cross section of FIG. 7A, and a stopper portion 68 is integrally formed on the back side of the operation hole 65 of the frame member 64, and the inner periphery of the operation hole 65 is The retaining portion 70 is integrally formed.

  Here, the deformation strength of the retaining portion 70 is made smaller than the deformation strength of the stopper portion 68 against the pressing of the protective plate. For this reason, when the protective plate 66 is pushed in from the front side, the retaining portion 70 is deformed and the protective plate 66 is pushed in and hits the stopper portion 68, so that it is built and held between the stopper portion 68 and the retaining portion 70 with one touch. be able to.

  Next, the operation of the embodiment of FIG. 5 will be described. In FIG. 5, the LED 24 is always driven to emit light, and the light from the LED 24 is incident from behind the frame member 64 made of a light-transmitting rubber material through the light guide 74, whereby the entire frame member 64 is The red light is emitted and the display as a red indicator lamp is performed.

In a fire, when the protective plate 66 held by the frame member 64 is pushed in from the outside, the stopper portion 68 is deformed, the protective plate 66 is detached from the frame member 64, and the pressure sensitive switch 26 is moved to the pressure sensitive switch 26 as shown by the protective plate 66a. Continued hitting, the resistance value of the pressure-sensitive switch decreased, and the detection circuit provided in the circuit unit 44 converted to a pressure-sensitive detection signal that increased according to the pressing force, and the pressure-sensitive detection signal exceeded the predetermined reference value At this time , a transmission signal is sent to the external fire receiver via the signal line 42.

  At the same time that the fire alarm is output by the fire receiver, a response signal is returned, thereby causing the LED 24 to blink or blink, for example. The light from the LED 24 is incident from behind the frame member 64 made of a translucent rubber material through the light guide 74, so that the entire frame member 64 emits light, and the operation of the pressure sensitive switch 26 is confirmed. A response is displayed.

  Even in the embodiment of FIG. 5, the red indicator lamp, transmitter, and speaker are integrated, so that the arrangement space for the device door surface and the like can be greatly reduced, and the disaster prevention device can be reduced in size and weight and installed. There is little damage to the design inside the building.

  Moreover, since the film-like pressure-sensitive switch 26 is used as a transmitter, the depth of the disaster prevention device can be reduced by reducing the depth even if it is integrated with the indicator lamp. Further, since the red indicator lamp and the transmitter are integrated, the location of the transmitter is obvious at the time of smoke, and high operability can be obtained even in the event of a fire.

  In the embodiment of FIG. 5, the provision of the protective plate 66 takes more time to restore the protective plate 66 than the embodiment of FIG. 2, but it can be made lighter and thinner than a transmitter having a conventional push button. In addition, since it is the same operation as the conventional transmission operation in which the operator pushes the protective plate 66 to operate, the transmission operation can be performed without a sense of incongruity in an emergency.

  In the embodiment of FIG. 5 as well, it is not necessary to integrate all of the transmitter, the red indicator lamp, and the speaker. For example, when all are separated, the transmitter can be made lighter and thinner than before. Moreover, even if it is the structure which integrated any two types, as shown to 1st Embodiment, the weight reduction and thickness reduction of the housing | casing which accommodates a disaster prevention device and a disaster prevention device can be performed.

  FIG. 9 is an explanatory view showing an embodiment of a pressure-sensitive sensor type operation switch device according to the present invention. FIG. 9 shows an example of an operation switch device provided in an operation unit of a fire receiver, for example.

  In FIG. 9, the switch unit 76 has a pressure-sensitive switch 26 disposed at the bottom of the hollow portion on the front surface of the switch housing 77, and a protective film 30 is provided on the front side thereof. A pressing plate for applying a pressing force uniformly may be disposed between the pressure sensitive switch 26 and the film 30 as in the embodiment of FIG.

  A predetermined voltage Vi, for example, Vi = −5 volts is applied to one of the lead terminals of the pressure-sensitive switch 26 provided in the switch unit 76, and the other lead terminal is connected to the inverting input terminal of the operational amplifier 48 constituting the detection circuit. Has been. The operational amplifier 48 is the same as in the case of the circuit unit 44 in FIG. 4, and outputs a pressure-sensitive detection signal Vo according to the equation (1), where Rs is the resistance of the pressure-sensitive switch 26.

  The output of the comparator 48 is given to an AD conversion port 80 of a processor 78 provided in the receiver, converted into digital data, and read into the determination unit 82. The determination unit 82 is a function realized by executing a program by the CPU.

  The determination unit 82 determines that the switch operation has been performed when the pressure-sensitive detection signal Vo based on the pressing force of the pressure-sensitive switch 26 exceeds a predetermined reference value, and a receiver corresponding to the determined switch operation. For example, processing such as alarm stop and recovery is executed.

  Further, the determination unit 82 determines that the switch operation has been performed when the state where the pressure-sensitive detection signal Vo exceeds the predetermined reference value continues for a certain period of time, and executes processing corresponding to the switch operation. It may be.

  Further, the operation switch device of FIG. 9 can be applied as it is to various operation switches provided in the disaster prevention related device as well as the operation switch of the fire receiver. In this case, the level for determining that the pressure-sensitive switch 26 has been operated in the determination unit 82, that is, the operating force can be appropriately set as necessary.

  For example, for an important operation switch, a high pressing force is set, so that the switch operation is performed by a reliable push that is sufficiently conscious of the switch operation. On the other hand, for a switch that requires a light touch in normal operation, the pressing force to be set can be lowered, the switch operation can be identified by performing a light switch touch, and necessary processing can be performed. .

  Further, the subsequent processing may be changed depending on the pressing force. For example, in the case of a strong pressing force, the actual function of the switch may be executed, and in the case of a light pressing force, guidance explaining the actual function of the switch may be performed. As described above, one of two mutually related processes may be performed by the pressing force of the switch.

  In the disaster prevention apparatus in the above embodiment, the speaker 32 is provided as an example of the acoustic device, but a piezoelectric buzzer or the like may be provided instead of the speaker 32.

  Moreover, about the apparatus storage box 10 of FIG. 1, although the apparatus storage box of the same size is shown in order to compare with the conventional three-part disaster prevention apparatus shown in FIG. The installation side of the equipment storage box 10 or the like on which the disaster prevention device 12 is installed in response to the downsizing may be reduced by reducing the installation space.

  Moreover, although it took the example installed in wall surfaces, such as a building, as said embodiment, this invention is applicable not only to this but a disaster prevention apparatus provided with apparatuses which perform transmission operation, such as a fire hydrant which has a transmitter.

  Moreover, the disaster prevention device of the present invention means not only a device housing box equipped with a transmitter, but also a device in which an indicator lamp and a speaker are integrated with the transmitter, and a transmitter alone.

  In addition, a dementia patient such as an elderly person may operate a transmitter by mistake to give an alarm. When an alarm is issued, an alarm is generated with a loud sound, so that the elderly may panic, but the present invention does not transmit unless the pressing operation of the pressure sensitive switch is continued for a predetermined time. False alarms due to operation can also be prevented.
