Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to an alarm device having an improved cover for a key hole of an automobile, a motorcycle or the like for theft prevention and tampering prevention.

<Prior Art> Conventionally, the lid of the key hole of this type of alarm device is often fragile, and even the key hole is destroyed, which requires a large amount of expense and labor to repair.

<Problems to be solved by the invention> Therefore, the lid of the key hole of the conventional alarm device of this kind is for an alarm device of such a degree that the sensor operates due to the vibration at the time of destruction and the alarm device installed at the separated position sounds. There was only one thing, so when I rushed to hear the warning, there was a problem that the area around the keyhole had already been destroyed.

Therefore, in order to solve such conventional problems, the present invention provides
The sensor operates due to vibration when the aggressor tries to remove the key lid by destroying the key hole or inserting a foreign object such as a driver, and the alarm device installed inside issues an alarm, the aggressor It is an object of the present invention to provide an alarm device that warns a user.

<Means for Solving the Problems> The structure of the present invention for achieving the object will be described with reference to FIGS. 1 to 3 corresponding to the embodiments.
The insertion part (1) formed in a shape that allows the sensor to detect abnormal noise or vibration when the state of contacting the metal of the key hole (3) of a car door or the like moves,
When the key lid (2), which is inserted into the key hole (3) and is planted and held in the knob, covers the key hole (3) while maintaining elasticity, the insertion portion (1) and the key hole An alarm device configured to operate an alarm device (6) when a sensor (5) detects an abnormal sound such as a click sound generated between the metal in (3) or a slight vibration, and the insertion. Department (1)
The alarm device has the above-mentioned structure, which is formed by molding a metal piano wire into a lightning shape as shown in the drawings.

<Operation> Since the present invention has such a structure, the insertion portion (1) is vibrated from the outside even when the insertion portion (1) is inserted into the key hole (3) and the vehicle is left. Or, when the key lid (2) is pulled out, if vibration of the insertion part (1) moves the state of contact with the metal in the key hole (3) and an abnormal sound such as a click sound or vibration occurs, An abnormal sound such as the click sound can be input to the sensor (5) and the sensor (5) can immediately issue an alarm of the alarm unit (6).

<Embodiment> An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 to FIG. 3 are views showing an embodiment of the present invention. In this embodiment, (1) is an insertion part, in which a metal wire is bent and formed into a lightning shape, and inside the key at the time of insertion. The base is planted in the key cover (2) while maintaining elasticity so as to contact the metal fittings. Although the insertion part (1) has been described above as being bent into an electric shape, it may have another shape, but it should have elasticity so as to maintain contact so as not to be easily detached from the internal metal fitting when it is inserted. is necessary.

When the insertion portion (1) is in contact with the metal of the key hole (3) while maintaining elasticity, the insertion portion (1) can move to generate an abnormal sound such as a click sound or a vibration, which can be detected by the sensor. In addition, the insertion portion (1) is molded and held in the knob of the key lid (2) while being inserted into the key hole (3).
When such a key lid (2) covers the key hole (3), the insertion part (1) moves and an abnormality such as a click sound generated between the key lid (2) and the metal inside the key hole (3). An alarm device that activates an alarm device (6) when a sensor (5) detects a sound or a slight vibration, and the insertion part (1) is formed by molding a metal piano wire. It is an alarm device.

In the case of an automobile, the sensor (5) is usually incorporated in the mounting plate (4) inside the door, but it can be additionally attached to the outside if necessary.

It goes without saying that the key lid (2) of the present invention can be applied not only to automobiles but also to motor boats or alarm devices in remote warehouses.

Although the embodiments considered to be typical of the present invention have been described above, the present invention is not necessarily limited to only the structures of these embodiments, and the constitutional requirements referred to in the present invention and the purpose referred to in the present invention can be obtained. The present invention can be carried out with appropriate modifications within the scope of achieving the following effects.

<Effects of the Invention> As is apparent from the above description, according to the present invention, the sensor operates by inserting the insertion portion into the key hole and causing the aggressor to move the key lid or to give a vibration to the alarm device. Sounds and warns the perpetrator, and the perpetrator is psychologically atrophied and discourages further action on the perpetrator, leaving the key lid inserted in the keyhole. In this way, the keyhole is not destroyed, and it is possible to expect a remarkable practical effect that damage can be avoided.

[Brief description of drawings]

1 is a sectional view of the key lid of the alarm device of the present invention, FIG. 2 is a perspective view of the key lid of the alarm device of the present invention, and FIG. 3 is the key lid of the alarm device of the present invention inserted into a key hole. It is an external view. In the figure, (1) is an insertion part, (2) is a key lid, (3) is a key hole, (4) is a mounting plate, (5) is a sensor, and (6) is an alarm device.

Claims (2)

[Scope of utility model registration request] 1. An insertion part (1) formed in a shape that allows a sensor to detect an abnormal sound or vibration by moving the state of the key hole (3) in contact with the metal to generate elasticity. When the key lid (2), which is inserted into the key hole (3) in the state of being held and is planted and held in the knob, covers the key hole (3), the insertion portion (1) and the key hole (3) An alarm device for operating an alarm device (6) when a sensor (5) detects an abnormal sound such as a click sound or a slight vibration generated between the metal inside the bracket). 2.
