JPH11284711A - Portable telephone with crime-prevention function - Google Patents

Abstract

PROBLEM TO BE SOLVED: To protect one's body from a crime and danger without requiring carriage of a private crime-prevention alarm by adding a crime-prevention alarm function to a portable telephone set. SOLUTION: The hand strap 20 of the portable telephone set is restrained to a movable anchor member 22 mounted to a case. The base part 28 of the member 22 is, for example, circular, and is provided with an annular conductor 38 forming the movable contact point of a crime-prevention alarm operation switch. A pair of fixed contact points cooperating with the conductor 38 are provided inside of a case and these fixed contact points are connected to a prescribed circuit by wiring. Then the movable contact point and the fixed contact points constitute the crime-prevention alarm operation switch. In this telephone set, the member 22 of the strap 20 is normally held at a prescribed position by snap-fitting a projection to a semi-spherical recess. At the time of emergency, the switch is closed at the time of pulling the strap 20 and the crime-prevention alarm consisting of a buzzer rings.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a portable telephone with a security bell function.

[0002]

2. Description of the Related Art In recent years, robbery, intimidation, molestation, and other crimes are not small. Therefore, it is desirable to protect yourself from danger by ringing a security bell when a crime or danger is encountered. For this reason, in recent years, the number of people carrying a portable security bell has increased. Also, when your body is buried under rubble or you are in a mountain in the earthquake, it is desirable to let others know your location by sounding a security bell.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a security bell function by using articles usually carried by most people without carrying around a dedicated security bell. To provide articles.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention is to provide a mobile phone with a security bell function which is obtained by adding security bell means to a mobile phone. Today, many people carry mobile phones. Therefore, by adding a security bell function to a mobile phone, it is possible to protect yourself from a crime by ringing the bell of the mobile phone without particularly carrying a dedicated security bell. When your body is buried under rubble in an earthquake, you can let others know your location and location by sounding a security bell.
If the user carries the mobile phone of the present invention, it is not necessary to carry a dedicated security bell, so that his belongings can be minimized.

[0005] In a preferred embodiment, the portable telephone with a security bell function is designed so that the security bell rings when a hand strap is pulled. With such a configuration, the security bell can be sounded only by pulling the hand strap, and the operation can be extremely simplified. Also, a test push button for testing whether the security bell sounds normally can be provided. In this way, the security bell can be reliably operated when necessary.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to FIG. 1, a mobile phone 10 according to the present invention has a case 12, in which a communication circuit and a battery (not shown) are incorporated, a dial button 14, a liquid crystal display, and a liquid crystal display. A display unit 16, an extendable antenna 18, a hand strap 20, and the like are provided.

[0007] As shown in FIGS. 2 and 3, the hand strap 20 is locked to a movable anchor member 22 mounted on the case 12. The anchor member 22 has a U-shaped head 24, an elongated shaft 26 and a base 28, and the hand strap 20 is wound around a pin 30 traversing the head 24. The anchor member 22 is inserted into the stepped hole 32 of the case 12.

As shown in FIG. 3, hemispherical projections 34 are formed on both sides of the head 24, and these projections 34 correspond to the corresponding hemispherical shaped holes provided in the stepped holes 32 of the case 12. The recess 36 is adapted to be snap-fitted.

As can be clearly seen from FIG. 2, the base 28 of the anchor member 22 is, for example, circular, and is provided with an annular conductor 38 forming a movable contact of a security bell operating switch. As shown in FIG. 3, a pair of fixed contacts 40 cooperating with the annular conductor 38 are provided inside the case 12, and these fixed contacts 40 are connected to a circuit to be described later by wiring (not shown). ing. The movable contact 38 and the fixed contact 40 constitute a security bell operation switch 42 (FIG. 4).

As shown in FIG. 1, the case 12 can be provided with a test push button switch 44.

FIG. 4 shows an example of a circuit configuration of the security bell device 50.
Shown in The security bell device 50 can be composed of a buzzer drive circuit 48 connected in series to a battery 46, a security bell operation switch 42 linked to the hand strap 20, and a test push button switch 44.

The mode of operation and use of the mobile phone 10 with a security bell function will be described. When used as a mobile phone, the mobile phone 10 can be operated in the same manner as a normal mobile phone. By pressing the test push button switch 44, it is possible to test whether the security bell sounds normally.

Normally, the anchor member 22 of the hand strap 20 is held at the position shown in FIG. 3A by the protrusion 34 being snap-fitted into the hemispherical recess 36. In an emergency, when the hand strap 20 is pulled as shown in FIG. 3 (B), the switch 42 is closed and the security bell made of a buzzer sounds.

[0014]

[Effect of the Invention] Today, many people carry a mobile phone, but if a mobile phone with a security bell function of the present invention is carried, the security bell can be sounded when a burglary or a molestation is encountered. Can protect you from danger. In addition, when the body is buried under the rubble in the earthquake disaster or when distressed in the mountains, you can inform others of your existence and location by sounding a security bell. Further, with the mobile phone of the present invention, it is not necessary to carry a dedicated security bell, so that the belongings can be minimized.
