Further, a lead wire connecting the second and third detecting means 2 and 3 and the message vocalization circuit 8 and a lead wire connecting the message vocalization circuit 8 and the light emitting diodes in the display windows 4d and 4e. 8a is housed in the cable cover 1c (see FIG. 4).

Next, the structure of the first detecting means 7 will be described with reference to FIGS. Reference numeral 7a denotes an operating rod which is slidably supported and attached to the bottom surface of the case 5 having a raised portion 7a ₁ on the tip side, and 7b has one end abutting the side wall of the case 5 and the other end having a protrusion 7a of the operating rod 7a. _A spring that abuts ₂ and constantly biases the operating rod 7a toward the outside, 7c is a fixed contact plate fixed to the bottom surface of the case 5, 7c
Reference numeral d denotes a movable contact line whose one end is fixed to the case 5, the other end projects from the bottom surface of the case 5 to the back surface, and the intermediate portion is on the upper surface of the operating rod 7a.

Next, the operation will be described based on the above-mentioned structure. When the fire extinguisher body 1 is placed at a predetermined place, the movable contact line 7d protruding from the case 5 to the rear surface thereof.
Since the floor surface pushes up against the spring force of itself, the movable contact line 7d and the fixed contact plate 7c are separated from each other, and thus the switch is in the off state. In this state, the operating rod 7a is pushed outward by the spring 7b.

When the fire extinguisher body 1 is mounted on a predetermined wall surface, the operating rod 7a is pushed by the wall surface against the spring force of the spring 7b, so that the raised portion 7a ₁ of the operating rod 7a is pushed. Portion pushes up the movable contact line 7d, so that the movable contact line 7d is separated from the fixed setting plate 7c and is in an off state as a switch.

When the fire extinguisher body 1 is installed in a predetermined place and lifted, the movable contact line 7d contacts the fixed contact plate 7c by its own spring force, and when removed from the wall surface, the spring 7b. Since the protrusion 7a ₁ is pushed out by the spring force of, the movable contact line 7d comes out of the position of the movable contact line 7d, so that the movable contact line 7d becomes free and contacts the fixed contact plate 7c. That is, the switch is turned on.

Next, the message vocalization circuit 8 is shown in FIG.
Will be explained together. E is a battery as a power source, 2 and 3 are the second and third detecting means (hereinafter simply referred to as switch 2 and switch 3), and 7 is turned on when the fire extinguisher body 1 is lifted or removed. It is a switch (first detecting means).

R is a relay having one contact r, Tr ₁ is a transistor, D ₁ is a diode, C _{1 to} C ₃ are capacitors, R _{1 to} R ₉ are resistors, C is a comparator, A ₁ and A
₂ is an AND circuit, O _{1 to} O ₄ are OR circuits, N is a NOR circuit, I is an inverter, and LEDs _{1 to} LED ₂ are light emitting diodes arranged on the back surfaces of the arrow windows 4 d and 4 e of the cover 4 described above. Further, 8a is a ROM in which voice message data is written, 8b is a voice synthesis circuit, 8c is a clock circuit, 8d is a ring counter circuit, 8e is a frequency dividing circuit, and 8f.
Is a power-on reset circuit, and 8g is a speaker.

Next, to explain the operation based on the above-mentioned circuit configuration, when the fire extinguisher main body 1 is placed on the floor or attached to a pillar or the like, the switch 7 is in the off state, so the voice utterance circuit. 8 does not work at all. When the fire extinguisher body 1 is lifted from the floor or removed from the pillar in this state, the switch 7 is turned on. When the switch 7 is turned on, the capacitor C ₁ is charged via the diode D ₁ , and when the terminal voltage V _c due to this charging becomes higher than the voltage V _ref divided by the resistors R ₁ and R ₂ , the comparator C
Output becomes high level, and the transistor Tr ₁ turns on.

Since the contact r of the relay R connected in parallel with the switch 7 is turned on when the transistor Tr ₁ is turned on, the switch 7 is turned off while the relationship of voltage V _c > voltage V _ref is established. Even in this case, the closed state of the contact r is maintained. Then, the voltage V _c gradually decreases as the charge of the capacitor C ₁ is discharged through the resistor R ₁ . Therefore,
Depending on the constants of the capacitor C ₁ and the resistor R ₁ ,
Continue supplying voltage to the circuit surrounded by the broken line.

When power is supplied to the circuit surrounded by the broken line, the ring counter 8d always counts by the clock signal from the clock circuit 8c, and the output signal thereof advances the lower address signal of the ROM 8a. . Then, the messages 1 to 3 are appropriately reproduced with the switches 2 and 3 turned on and off, and the relationship is as shown in Table 1. The address is A1 of ROM8a.
2, use A13.

[Table 1]

Therefore, since the switches 2 and 3 are in the off state when the power is supplied, the message 1
The data (please pull out the pin) is sent from the ROM 8a to the voice synthesis circuit 8b and repeatedly emitted by the speaker 8g. At this time, since the low-level reset signal is input from the power-on reset circuit 8f to the reset terminal of the ring counter circuit 8d, the data of the message 1 is sent from the head.

Further, in this state, the OR circuit O ₁ ,
Since the output of O ₃ is low level, the light emitting diode L
The ED ₁ lights up, but at this time, the frequency dividing circuit 8e performs a blinking operation to indicate the direction of the pin 1a.

Further, when the switch 7 is on and the hose 1d is disconnected and the switch 3 is turned on, the message 1 must be emitted. Therefore, in the present embodiment, the AND circuit A ₁ is connected so that the outputs of the OR circuits O ₂ and O ₄ do not become high level, and the message 1 is emitted.

If the pin 1a is pulled out while the message 1 is being emitted, the switch 2 is turned on, so that the address A12 becomes "1" and the address A13 becomes "0". Therefore, the data of the message 2 (Please point the hose to the fire source) is sent from the ROM 8a to the voice synthesis circuit 8b and is repeatedly emitted from the speaker 8g.

At this time, since a positive differential waveform is output from the differential circuit composed of the capacitor C ₂ and the resistor R ₆ , a low level output is sent from the NOR circuit N and reset via the AND circuit A _2. The signal is sent and the data of the message 2 is sent from the beginning, so that the message 2 is emitted from the head.

Further, since the OR circuits O ₁ and O ₃ are at the high level, the light emitting diode LED ₁ is turned off, while the OR circuit O ₂ is at the low level by the inverter circuit I, so that the OR circuit O ₄ is also at the low level. At the level, the light emitting diode LED ₂ blinks to indicate the direction of the hose 1d.

The unplugged from the locking piece 1c ₁ the hose 1d while the message 2 has been sounded, the switch 3 is turned on, the address A12 is "1", the address A13 is also "1". Therefore, the data of the message 3 (grip the lever) is sent from the ROM 8a to the voice synthesizing circuit 8b and is repeatedly emitted from the speaker 8g.

At this time, since a positive differential waveform is output from the differentiating circuit constituted by the capacitor C ₃ and the resistor R ₇ , the reset signal is sent from the AND circuit A ₂ by the same operation as described above, and the message 3 The data is transmitted from the beginning, so that the message 3 is emitted from the head and the OR circuits O ₂ and O ₄ are at a high level, so that the light emitting diode LED ₂ is turned off.

Then, the sound output of the above-mentioned message 3 is
When the specific time of the time constant circuit formed by the capacitor C ₁ and the resistor R ₁ elapses, the circuit is stopped and all circuit operations are completed.

Although the above embodiment has been described with respect to the case of the logic circuit, an integrated circuit or a CPU may be used, and in this case, the specific time for holding the ON state of the relay R is continuously called. It is also possible to hold it by counting the number of times of message 1, and
The change from OFF to ON of the switches 2 and 3 can be easily detected by software instead of being detected by the differentiating circuit.

[0035]

As described above, according to the present invention, when the fire extinguisher body is lifted or removed, the switch is turned on and the first message is emitted, and when the pin is removed, the second message is emitted. Further, since the third message is emitted when the hose is pulled out, the operator can appropriately perform fire extinguishing work in a fire without panicking.

Further, since the display showing the direction of the pin is made at the same time as the sounding of the first message and the display showing the direction of the hose at the same time as the sounding of the second message, the operator This has the effect of being able to confirm the position of the pin and the position of the hose and to carry out fire extinguishing work more accurately.
