Description

[Technical Field]

[0001] The present invention relates to a portable alarm device for crime prevention, and more particularly to a portable device that has the function of making an alarm by a visually significant signal and a radio signal in an environment or situation where sound cannot be emitted.

[0002] Furthermore, this device is highly decorative and has a form that blends naturally into everyday life, making it a product that combines security and fashion. [Background technology]

[0003] Many conventional portable security devices are designed to alert those around to danger with a loud buzzer. These devices are primarily intended for children going to and from school, and have issues with design and usage scenarios that make them unsuitable for everyday use by adult women and others. Furthermore, they are difficult to use in situations where sound cannot or should not be emitted (e.g., when the assailant is nearby, in a public place, etc.), and there is a lack of an effective means of reporting a crime.

[0004] On the other hand, while smartphones have flashing LEDs and flashlight functions, they do not transmit meaningful signals and are not a means of reporting an emergency. Furthermore, taking out a mobile phone and contacting the police in an emergency places a heavy psychological and time burden on users, and they lack the ability to respond quickly.

[0005] One prior art is a portable security device that adds a security function that emits an alarm to a mobile phone terminal, allowing it to be used as a mobile phone in normal times and as a security device that emits an alarm in emergencies. This device is characterized by having a security mechanism that is built into or detachably attached to the mobile phone terminal and that has an alarm sounding unit that emits an alarm when the switch is operated (Patent Document 1).

[0006] Another example is a portable security device that can reliably activate an alarm in an emergency. The security device comprises a security device main body and a wearing belt attached to the security device, with the wearing belt having a built-in conductive line. The security device main body is provided with an alarm output means and a disconnection monitoring signal generation means, and the disconnection monitoring signal flows through the conductive line. If the belt is cut during use, for example, and the electrical continuity is interrupted, the alarm output means is automatically activated and an alarm is issued. This solves the conventional problem of no alarm being issued even if the device is stolen by a criminal, enabling more reliable security measures (Patent Document 2).

[0007] [Patent Document 1] Patent application No. 11-287027 [Patent Document 2] JP 11-175853 Summary of the Invention [Problem to be solved by the invention]

[0008] The purpose of this invention is to solve the above problems and provide a portable security device that combines security performance and design, and that can make clear SOS calls visually and wirelessly even in situations where sound cannot be made.In addition to a simple buzzer sound, it also has a fake ringtone and lighting function that can be used depending on the situation, and it can also send a signal including location information to security companies, police, family members, etc. using a wireless communication module such as Bluetooth or LoRa, allowing for immediate notification. [Means for solving the problem]

[0009] To solve the above problems, the portable security device of the present invention has the following configuration: Namely, when operated, a high-brightness LED is controlled to emit light by alternating between lighting and non-lighting for a certain period of time, and the lighting pattern is used to generate an SOS Morse code.

[0010] The LED may be configured to switch between a first color corresponding to dots and a second color corresponding to dashes, thereby visually displaying a Morse code pattern by a combination of color changes and / or flashing. Note that the first and second colors may be the same.

[0011] In addition to the LED flashing, a fake ringtone or buzzer sound may be selectively emitted by operation.

[0012] The device may be characterized by including a communication module that, when operated, automatically transmits an emergency signal to a security company, the police, or a registered terminal via a predetermined communication means.

[0013] Here, the above operations include "push operation (pressing a button)", "pull operation (type activated by pulling out a pin or strap (used in many commercially available security alarms)", "tilt / acceleration detection operation (automatically activated when tilting at a certain angle or more or sudden movement (vibration or falling) is detected)", "voice / sound pressure detection operation (activated when it detects sound pressure above a certain level or sounds of a certain frequency, such as screams, loud voices, or the pronunciation of a code word)", and "contact / touch sensor operation (activated by touching a specific part or continuing to touch it for a certain period of time (can be used even when wearing gloves)". [Effects of the Invention]

[0014] This device is capable of reporting even in situations where sound cannot be made, and is equipped with the ability to transmit "meaningful signals" visually and wirelessly. It also has an excellent design, and is expected to increase the rate of carrying it by removing the psychological hurdle of "not wanting to carry it" that is common with conventional security devices.

[0015] Furthermore, since it can be given as a gift without any awkwardness, it also plays a role in establishing crime prevention awareness and promoting its cultural spread. Another advantage of this device is that its structure is simple and suitable for mass production, and it is expected to be applied not only to the crime prevention market but also to a wide range of fields such as disaster prevention and nursing care support. Furthermore, by using Morse code, it has high versatility as a globally common means of communication and is internationally recognizable, making it suitable for use in a variety of environments.

[0016] In addition, the function that supports a "natural withdrawal" by utilizing fake ringtones can support crime prevention actions while reducing the psychological burden on users.

[0017] It also has an instant reporting function via wireless communication, which allows users to report to the police or security companies with location information without having to operate their mobile phone, making it highly compatible with modern smart security infrastructure. [Brief explanation of the drawings]

[0018] [Figure 1] Image of the product related to this invention (surface) [Figure 2] Image of the product related to this invention (back) [Figure 3] Image of the product (side view) related to this invention DETAILED DESCRIPTION OF THE INVENTION

[0019] The following describes embodiments of the present invention. However, the design may be modified as needed without departing from the spirit of the present invention, and known patent documents and conventionally known techniques may be used.

[0020] The portable security device of this invention is designed to be easy to carry on a daily basis, yet capable of reporting abnormalities in an emergency in a reliable and versatile manner, and is comprised of a decorative bag charm-shaped housing equipped with the following elements: "Bag charm-shaped" refers to an accessory-like shape and structure that can be attached to a bag or other personal belongings.

[0021] The exterior housing is disc-shaped, approximately 45 mm in diameter and 15 mm thick, and features a floral motif and the "Amule" logo on its surface. Made from a combination of matte gold-tone ABS resin and synthetic leather, it looks like a decorative accessory, eliminating the psychological resistance to carrying it around all the time and contributing to increased portability (Figure 1). The housing is also water-resistant (equivalent to IPX4), making it suitable for use outdoors or in the rain.

[0022] The device has a push button (1) on the back as the main operating means, and multiple functions can be switched using this single button. The specific operating modes are as follows (Figure 2).

[0023] Pressing the button once activates a constant-on mode with a high-brightness white LED, helping to improve visibility and presence in dark places. Pressing the button twice causes the same LED to flash in accordance with the rhythm of the internationally recognized Morse code "SOS" (...---...), functioning as a means of visually communicating an emergency even in situations where sound cannot be made (Figure 3). This flashing control is configured to be clearly identifiable as a signal by setting, for example, the dots to 0.3 seconds, the dashes to 0.9 seconds, and the interval between dots to 0.3 seconds. The three lines at the bottom of Figure 3 are a schematic representation of the LED light.

[0024] Furthermore, pressing and holding the button for two seconds will play a fake ringtone similar to a smartphone ringtone. This creates a "trigger" for the user to naturally move away from conversations or spaces with unpleasant people, reducing psychological stress and indirectly supporting crime prevention behavior. Such acoustic effects enable social understanding of crime prevention behavior and less awkward behavior, making them particularly useful for young people, women, and the elderly.

[0025] Pressing and holding the button for three seconds activates a loud buzzer at approximately 120 dB, and at the same time activates the built-in wireless communication module, automatically sending an alert signal to linked devices such as pre-registered smartphone apps and security company receivers. This communication module can use wireless methods such as Bluetooth Low Energy (BLE), which combines power saving and immediacy, or LoRa and NB-IoT, which are designed for wide-area communication. This enables quick alerts and location information sharing without the user having to operate their smartphone, making it highly compatible with modern smart security infrastructure.

[0026] This device achieves this multifunctionality with a simple operating system, and the circuit board, LED, speaker, communication module, etc. are compactly arranged inside. The power supply has a built-in lithium-ion battery that can be charged via a USB-C terminal, allowing for repeated use.

[0027] In addition, the speaker hole (2) and charging port (3) are located on the back of the housing, without compromising the design of the front. In this way, this device provides multi-layered security support by combining multiple output methods - visual, audio, and communication - in a way that blends into everyday life, realizing a new form of security device that combines security functionality with design.

[0028] The activation of this device is not limited to push-button operation, and other input means can be combined. For example, an alarm mode can be activated by pulling out a strap or ring, or an automatic activation can be achieved by detecting unnatural vibrations, falls, or other movements using a built-in acceleration sensor or tilt sensor. This allows for automatic notification even in situations where it is difficult for the user to operate the device, further increasing its effectiveness.

[0029] In terms of wireless communication functionality, the built-in communication module allows for selective use of low-power wide-area communication standards such as Bluetooth Low Energy (BLE), LoRa, and NB-IoT. This allows for short-range connection with smartphone apps, as well as direct connection with security company receiving terminals and local government monitoring systems without the need for a smartphone. These wireless notifications can be configured to operate in parallel with visual and audible warnings using LEDs and buzzers, ensuring multiple crime prevention measures and providing the optimal warning method depending on the situation. [Industrial Applicability]

[0030] This invention relates to a portable security device that can report emergencies visually or wirelessly even in environments where sound cannot be emitted. It can be used for personal security purposes as well as in a wide range of settings, including public transportation, schools, nursing homes, and night shifts. Its simple structure, ease of mass production, and design and gift-giving qualities make it suitable for industrial applications not only in the security goods market, but also in a variety of other fields, including lifestyle products, disaster preparedness supplies, and the medical and welfare fields. Furthermore, the use of Morse code (e.g., SOS) for information transmission makes it suitable for international use regardless of language. [Explanation of symbols]
