[0003]

[Problems to be solved by the invention]

 However, conventional car doors do not have an alarm device, so if you park and open the door during dark and poor visibility nights, it is difficult for other drivers to recognize that the door has been opened. Therefore, motorcycles and passenger cars may collide with open doors. In addition, it is required to ensure the safety of the driver when the door is opened. In addition, theft has occurred while parking. SUMMARY OF THE INVENTION Accordingly, a main object of the present invention is to provide an alarm device that warns a running car or motorcycle not to collide with a door when a parked car has the door open. It is a further object of the present invention to provide an alarm device for preventing a theft accident during parking.

[0004]

[Means for Solving the Problems]

 According to a first aspect of the present invention, there is provided an alarm device provided at a side end of a door body of a vehicle, the contact device detecting opening and closing of the door body. A switch, an alarm lamp that lights when the contact switch detects opening of the door body, and a buzzer that generates an alarm sound in synchronization with the alarm lamp. Therefore, even if you park and open the door during dark nights with poor visibility, you can warn other drivers that the door has opened. According to the alarm device of the second aspect of the present invention, the contact switch includes an outer cover provided on the door body, a rubber cap protruding from the outer cover and capable of abutting the vehicle body, and a + It has an electrode leaf spring, an − electrode leaf spring whose end can contact the + electrode leaf spring, and a coil spring that biases the + electrode leaf spring. Therefore, a simple structure can be obtained, and it can be manufactured at low cost.

According to the alarm device of the present invention, the alarm lamp and the buzzer are connected to the open / close control circuit. Therefore, the warning lamp flashes when the door is opened, and the buzzer sounds intermittently in synchronization with the blinking. Further, according to the alarm device of the present invention, the alarm lamp and the buzzer are activated when the door is opened, so that the theft accident during parking can be prevented.

[Embodiment of the invention]

 Hereinafter, an example showing an embodiment of the present invention will be described with reference to the drawings.

As shown in FIGS. 2 to 5, an alarm device according to an embodiment of the present invention has an alarm lamp 51 and a buzzer 52 connected in series, and is formed at a side end of the door body 2. An alarm device 5 fitted in the fitting groove 21 and a contact switch 53 connected in series with an alarm lamp 51 and a buzzer 52, and an electric circuit is provided by using a storage battery 6 installed in an automobile. To form The alarm device 5 includes several alarm lamps 51, a buzzer 52, and an open / close control circuit board 511. The positive electrode of the storage battery 6 is connected to one side of a contact switch 53, the other side of the contact switch 53 is connected to the buzzer 52 side of the alarm device 5, and the alarm lamp 51 side of the alarm device 5 is connected to one side of the storage battery 6. To form an electric circuit.

As shown in FIGS. 4 and 5, the alarm lamp 51 and the buzzer 52 are connected in series via an open / close control circuit board 511.

As shown in FIGS. 3A and 3B, the contact switch 53 includes an outer lid 511, a spring 532 as a coil spring, a leaf spring 533 as a positive electrode spring, and a negative electrode spring. And a rubber cap 535. The outer lid 531 is attached to the lower end of the door main body 2, and a leaf spring 533 and a leaf spring 534 are provided horizontally from both sides of the outer lid 531 so as to overlap each other at one end. A spring 532 is provided in the outer lid 531 so as to connect the spring plate 533 and the door body 2. On the opposite side of the portion where the leaf spring 533 and the spring 532 are in contact, a rubber cap 535 is mounted to protrude outside the outer lid 531.

When the door is closed as shown in FIGS. 3A and 4, the vehicle body 8 presses the rubber cap 535 of the contact switch 53, and the rubber cap presses the spring 532. The spring 534 is in a separated state. Therefore, the electric circuit is cut off, and the alarm lamp 51 and the buzzer 52 are cut off and do not operate.

When the door is opened as shown in FIG. 3B and FIG. 5, the vehicle body 8 separates from the rubber cap 535 of the contact switch 53, and the spring 532, which has been pressed, expands and is connected to the spring 532. The leaf spring 533 is pressed against the spring and returns to its original position. Therefore, the leaf spring 533 comes into contact with the leaf spring 534, an electric circuit is formed, the alarm lamp 51 and the buzzer 52 are energized, and the alarm lamp and the buzzer can be operated.

After the alarm device of this embodiment is installed, the inner lining 4 is attached to the inside of the door body.
