Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a dozing prevention device that prevents dozing off while driving a car or in class.

(Prior Art and Problems) Conventionally, a hat with a built-in alarm device that issues a warning when tipped has been proposed to prevent dozing off. If you lower your head to pick up something that has fallen on the floor or pull the handbrake installed on the floor, the alarm system will activate and emit an alarm, which is not only annoying, but also causes problems in classrooms. Currently, it cannot be used in places where hats cannot be worn, and it has not been put into practical use.

(Purpose of the present invention) The present invention has been made in view of the above-mentioned conventional problems, and it is an object of the present invention to provide a dozing prevention device that does not operate except when dozing off, and is not limited to the places where it can be used. The purpose is to

(Means for Achieving the Purpose) To achieve this goal, the present invention has been developed by focusing on the fact that the hands and fingers relax when a person falls asleep. A support pin is erected at one end of one side of the cylindrical body in which a power source for operating the voice generator and a circuit connecting the power source and the alarm voice generator are built, and the circuit is connected to the support pin.
The base end of a substantially V-shaped leaf spring-like switch plate that turns on and off is attached, one piece of the switch plate is fixed to the cylinder body, and the other piece can be opened and closed, and the support pin It has a structure in which a locking piece for locking the switch plate between the fingers is formed at the tip.

(Function) In the doze prevention device having the above structure, when the tip of the switch plate is open, the contact of the circuit is turned on and the alarm sound generator is activated. Therefore, if you put the dozing prevention device on your hand by placing the switch plate between your fingers with the cylinder body on the outside and the locking piece on the inside, the tip of the switch plate will close and the circuit will be turned off. The alarm horn will not work.
When the wearer of the dozing prevention device falls asleep, the user's fingers relax and the tip of the switch plate opens due to its spring force, turning on the circuit and activating the alarm sounder to emit an alarm sound. Therefore, the wearer can be woken up from a doze by this alarm sound.

Furthermore, when the dozing prevention device is not in use, the operation of the warning sound generator can be stopped by closing the tip of the switch plate and placing a locking device such as a cap over the tip of the switch plate. can.

(Example) The present invention will be described below with reference to an illustrative example.

Reference numeral a denotes a doze prevention device, which is composed of a device main body 11 and a switch plate 12. The preventer main body 11 is formed into a substantially rectangular cylindrical body, and has a built-in alarm sound generator 13 and a button-shaped dry battery 14 that serves as a power source for operating the alarm sound generator 13. 14 and the alarm sounder 13 are connected to the circuit 15
connected by. Contacts 15a and 15b are provided on the + (plus) side of the circuit 15, and are turned on and off by a switch plate 12, which will be described later.
It is made to be.

Incidentally, AA type dry batteries or the like may be used as a power source, but button type dry batteries as in the above embodiment are preferable in view of reducing the weight of the doze prevention device a.

The switch plate 12 is made of a steel plate that can conduct electricity to approximately V.
The base end 12a is formed into a leaf spring shape.
is attached to a support pin 16 erected at one end of one side of the preventer main body 11. Further, one V-shaped piece 12b of the switch plate 12 is fixed to one side of the preventer main body 11, and only the other piece 12c can be opened and closed. Furthermore, the switch plate 1
A projecting piece 18 is formed on the lower edge near the tip of the other piece 12c of 2 to engage with the engagement hole 17 of the preventer main body 11, which is bored at the position where the contacts 15a and 15b of the circuit 15 are arranged. When the tip of the switch plate 12 opens and closes, the protrusion 18 connects to the contact 15.
a, 15b so as to come into contact with and separate from them.

Note that the switch plate 12 is not limited to a steel plate that can conduct electricity as in the above embodiment, but may be made of an elastic resin material, and a conductive plate is fixed to the surface of the protruding piece 18 facing the contacts 15a, 15b. But that's fine.

Furthermore, the relationship between the switch plate 12 and the contacts 15a, 15b is not limited to that of the embodiment described above; for example, the relationship between the engagement hole 17 of the preventer main body 11 and the switch plate 1
2, the contacts 15a and 15b are exposed on one side of the preventer main body 11, and the contacts 15
The lower edge of the switch plate 12 may be brought into contact with the contacts 15a and 15b, or a switch lever may be provided between the switch plate 12 and the contacts 15a and 15b, and the switches may be turned on and off using the switch lever. Good too.

A thin elastic locking piece 19 extending in the left-right direction is formed at the tip of the support pin 16, and by locking the locking piece 19 inside the finger, the switch plate 12 can be moved. The doze prevention device a is attached to the hand by being locked between the fingers.
Therefore, if you hold your hand in this state, switch board 1
2 is closed and the circuit 15 is turned off.

(Effects of the Present Invention) As described above, according to the present invention, when the user falls asleep and his/her fingers are relaxed, the switch plate 12 opens and the alarm sound generator is activated to emit an alarm sound.
You can definitely prevent falling asleep. Therefore, if the drowsiness prevention device is used when driving a car, it is possible to eliminate drowsiness while driving and prevent accidents caused by this.

In addition, according to the present invention, all you have to do is insert the switch board between your fingers and hold it, so you can put it on with very natural movements such as gripping a handle or holding a pen, so you can easily put it on when you put it on. There is no discomfort,
Moreover, since it is small and lightweight, it does not become an eyesore, so it has the advantage of being able to be used freely in classrooms and the like.
