Abstract

PROBLEM TO BE SOLVED: To provide an alarm device which can be used as an anti-theft device in a stationary state or as a self-protection and snatching prevention device when carried. When a pin is inserted into a pin sheet, an electric circuit is closed and an alarm buzzer does not operate. When a pin is removed, an alarm buzzer operates to achieve protection and snatching prevention. In addition, the open end of the V-shaped switch spring of the elastic trigger device is exposed to the outside, and the open end is installed so as to be pressed by the article, thereby forming a disconnection state and preventing the alarm buzzer from being released. When the article is moved and the pressure to the open end is released, a passage state is formed and an alarm buzzer sounds.

[Prior art]

 While women are attacked by thugs at night roads, underpasses, elevators, etc., and theft cases cause social unrest, various devices and equipment have been developed for self-preservation, snatch prevention and anti-theft. Among them, horns and repelling sprays are typical of self-defense devices, but horns are inconvenient for emergency use, and sprays were ineffective unless used at short distances. On the other hand, to prevent theft, there is a system in which the camera is connected to a monitor with an electric wire for monitoring. This system has achieved a certain effect, but installation of this system was costly. And there were no alarm devices on the market that had both protection and anti-theft functions.

【Example】

 As shown in FIGS. 1 and 2, the alarm device of the present invention includes one casing, one pin 2, and one elastic trigger unit 3. The casing 1 is formed by fitting two upper and lower boxes, and can be designed as a beautifully shaped decorative article. Inside the casing 1, one electric circuit board 11, one alarm buzzer 12, one pin sheet 13, one battery sheet 14, one earphone sheet 15, one switch sheet 16 and one valve 17 are provided. Is provided. The electric circuit board 11 is connected to the alarm buzzer 12 and the battery sheet 14, and the pin sheet 13, the earphone sheet 15, and the switch sheet 16 are all fixed on the electric circuit board 11. The pin sheet 13 and the earphone sheet 15 are respectively located at both ends of the electric circuit board 11, and inside each of them, one spring piece 131, 151 is in elastic contact with the connecting piece 132, 152 ( (See FIG. 4). The switch seat 16 has an operation knob 161 which is used for switching an electric circuit and is connected to a valve sheet 171 to which the valve 17 is screwed. In addition, another protruding portion 18 is provided at the lighting end of the casing 1 (FIG. 10), and a chain 41 is connected, whereby the present invention can be hung on a user's bag or clothes, and is convenient for carrying. It is also said to be able to provide effects as decorative items.

The pin 2 has one connecting portion 21 at its upper end, and if the connecting portion 21 is connected to the key holder 4, the casing 1 becomes a decoration of the key holder. When the pin 2 is inserted into the casing 1 and inserted into the pin sheet 13, it cuts off the electric circuit and when the pin 2 is withdrawn from the pin sheet 13 and the casing 1, as shown in FIG. It restores the electrical circuit to conduction, thereby activating the alarm buzzer 12 and generating a sound (see circuit C in FIGS. 4 and 6). Thus, the present invention can provide a self-preserving effect by the operation of pulling out the pin 2.

The elastic trigger unit 3 is formed by connecting one earphone connector 31 to an elastic trigger device 33 by an electric wire 32, and the earphone connector 31 can be inserted into the earphone sheet 15 of the casing 1 and connected to the elastic trigger device. The device 33 is provided with a V-shaped switch spring 332 in one case 331 so that its open end protrudes from the case 331, and shuts off an electric circuit when the switch spring 332 receives pressure (see FIG. 7), and when the pressure is released, the electric circuit is brought into a passage state (see FIGS. 3 and 8) so that the alarm buzzer 12 is sounded. At this time, the circuit becomes the D circuit in FIG. The present invention provides a device for preventing theft by sandwiching the open end of the switch spring 332 in an appropriate place of the article, and furthermore, when the elastic trigger unit 3 and the casing 1 are removed, the circuit C in FIG. Since the voice is generated through the communication, an alarm effect can be obtained.

With the above configuration, when the casing 1 and the pin 2 are combined, it is possible to control whether or not the alarm buzzer 12 is operated by inserting or removing the pin 2. Is pulled out, the alarm buzzer 12 generates an alarm sound, and the function of the alarm device for personal protection can be achieved. Alternatively, by combining the elastic trigger unit 3, the open end of the switch spring 332 is inserted under the article 5 such as a jewel box, a computer, a safe or the like and pressed (FIG. 8), or inserted into a gap between a window or a door. If it is pinched (Fig. 9) and other parts are placed out of sight, the article 5 is moved or the window is opened, the electric circuit runs through and the alarm buzzer 12 is activated, and the effective theft is performed. A protective effect is achieved and its installation is very simple, only the open end of the switch spring 332 needs to be clamped in a suitable place under pressure. Further, when the intruder removes the elastic trigger unit 3 and the casing 1, the circuit C is activated and the alarm buzzer 12 sounds. In addition, a long chain 6 is connected to the pin 2 of the present invention, and a clip 61 is provided at another end of the chain 6 (FIG. 11). Alternatively, when the pin 2 is inserted into the casing 1 and the casing 1 is placed in the bag, the pin 2 is pulled out of the casing 1 and the alarm buzzer 12 sounds, and the thug is thrown. It can surprise and prevent snatching. By operating the operation knob 161 of the switch sheet 16, light emission and disappearance of the bulb 17 can be controlled, thereby providing an emergency lighting effect.
