Description

[Detailed description of the invention] [Field of industrial application] The present invention is a portable crime prevention device that is equipped with a crime prevention sound generating means that generates a crime prevention sound based on a switch operation in a portable case. Regarding ingredients.

[Conventional technology]

Conventionally, as shown in FIG. 8, this type of portable security device includes a speaker 51 and a battery 5, which constitute the security sound generating means 2, in a portable case 50.
2. A switch 54 is known in which a switch 54 with a string 53 is pulled out of the case 50 to close a contact 54b in an electric circuit 55 including the speaker 51 and battery 52. (Unable to provide references).

[Problem that the invention attempts to solve]

In the case of this conventional portable security device, by pulling out the switch piece 54a of the operation switch 54, the contact 54b in the electric circuit 55 is closed, and the vibration of the speaker 51 produces a buzzer sound that is effective for crime prevention. Although it is possible to generate a cell phone, it is only used for crime prevention, and there is a very low possibility that it will be needed, so it is easy to forget to carry it, so it is not actually used much.

The purpose of the present invention is to make effective use of the functions of this type of portable security equipment by rationally modifying it.
It is possible to suppress wastage of water for flushing when women and girls use the toilet, and at the same time, by increasing the portability rate, it is possible to increase the utilization rate of security equipment.

[Means for solving problems]

The portable crime prevention device according to the present invention includes a crime prevention sound generating means that generates a sound effective for crime prevention based on a switch operation, and a crime prevention sound generating means that makes it impossible to distinguish between toilet sounds based on the switch operation, in a portable case. This device is characterized by incorporating an erasing sound generating means for generating an erasing sound, and its functions and effects are as follows.

[Effect]

With a single portable security device, it is possible to generate not only sounds that are effective in crime prevention, but also erasure sounds such as pseudo-washing sounds that make it impossible to distinguish between toilet sounds.
In order to eliminate the sound of defecation when using a flush toilet, it is not necessary to repeatedly flush flush water during one use, and waste of flush water caused by this can be suppressed.

[Effect of idea]

Therefore, by focusing on the physiological needs that always occur as long as we are alive, that is, the need to use toilets, we have incorporated into portable security equipment a function that generates a cancellation sound such as a simulated flushing sound that is necessary at this time. Not only can you reduce wastage of water for flushing when using the toilet, but
Along with this, the rate of carrying portable security equipment has improved, and the original utilization rate of security equipment has been increased.

Furthermore, by incorporating the crime prevention sound generation means and the erasure sound generation means, it is possible to configure the erasure sound generation means by also using the speakers, batteries, etc. that are the constituent members of the crime prevention sound generation means, and the structure can be improved. It is also possible to easily achieve the above-mentioned effects while simplifying and reducing costs.

〔Example〕

Hereinafter, embodiments of the present invention will be described based on the drawings.

Figure 1 shows a portable security device, which is housed in a portable case 1 that is approximately the size of a business card and has a thickness of 2 to 3 mm, and generates a sound that is effective for crime prevention based on the operation of a switch. Security sound generation means 2
and an erasing sound generating means 3 that generates an erasing sound such as a pseudo flushing sound that makes it impossible to distinguish the toilet sound based on a switch operation.

As shown in FIG. 2, the crime prevention sound generation means 2 includes a mode switching operation switch 4 for switching to the crime prevention sound generation mode, a control section 5 using a microcomputer, a D/A converter 6, an amplifier 7, and a speaker. 8. It is composed of a starting operation switch 9 that uses a temperature sensor that detects the temperature of the hand, and a battery 10 that serves as a power source for these, and the erasing sound generating means 3 is switched to an erasing sound generation mode. The control unit 5, D/A converter 6, amplifier 7, speaker 8, starting operation switch 9, and battery 10 of the security sound generating means 2 are used for other functions. It is configured.

The control unit 5 has an I/O port 5a and a timer 5.
b, and a ROM 5c and a CPU 5d that digitize and store security sounds and erasure sounds, respectively. In the security sound generation mode in which the mode switching operation switch 4 of the crime prevention sound generation means 2 is operated, when the operation signal of the starting operation switch 9 is output, the erasure sound generation means 3
Until the mode switching operation switch 11 is operated, the security sound data stored in the ROM 5c is transferred from the I/O port 5a to the D/A converter 6,
It is configured to output security sounds to a speaker 8 via an amplifier 7 and continuously generate security sounds. Furthermore, a mode switching operation switch 11 of the erasure sound generating means 3 is provided.
When the operation signal of the starting operation switch 9 is output in the erasing sound generation mode in which is operated, the erasing sound data stored in the ROM 5c is is output from the I/O port 5a to the speaker 8 via the D/A converter 6 and the amplifier 7, and the erase sound is generated for a certain period of time.

The mode switching operation switch 4 of the crime prevention sound generating means 2 and the mode switching operation switch 11 of the erasing sound generating means 3 are concealed by an operation panel sheet 12 on which various operation names and the like are printed.
The operation panel sheet 12 is also provided with a dummy switch 13 resembling a power switch and a heat-sensitive portion 9a of the start-up operation switch 9.

Next, another example will be described.

(a) In the above embodiment, the security sound generating means 2 and the erasing sound generating means 3 are selectively driven by the two mode switching operation switches 4 and 11 and the starting operation switch 9. However, the operating forms for both of these means 2 and 3 can be changed in various ways. For example, even in the erasure sound generation mode, when the security sound generation means 2 is operated, the security sound may be generated preferentially, and the current mode status may be displayed on an LED or the like. It may be configured as follows.

(b) As the erasing sound generated by the erasing sound generating means 3, music, bird calls, etc. may be used instead of the pseudo water washing sound. In short, any erasing sound may be used as long as it can make it impossible to distinguish between bowel movements and does not cause discomfort to the user.

(c) The crime prevention sound generated by the crime prevention sound generating means 2 includes a buzzer sound, a bell sound, or an audio scream sound. In short, any security sound may be used as the security sound as long as it is effective for crime prevention.

(d) Furthermore, as shown in Figures 3 to 7,
Other functions or structures may be added to the portable security device described in the above embodiments.
