Description

  The present invention relates to a bicycle light emitting device.

  Bicycles running at night are difficult to see, especially for drivers driving cars, and are prone to accidents.

  In order to enhance safety, a reflector plate is used that attaches to the mudguard of the rear wheel of the bicycle or the spokes of the wheel and reflects the light of the headlight of the car to alert the driver. Often.

  However, since the reflection plate has a limited angle of incident light that is effectively reflected with respect to the plate plane, the driver cannot view the reflected light satisfactorily depending on the incident angle, thus achieving the above object. I couldn't.

Therefore, various light emitting devices that can emit light by themselves and can be attached to a bicycle have been devised (for example, see Patent Document 1).
JP-A-10-129557

  However, the conventional light emitting device has a restriction that the power source is obtained from the generator of the headlight, so that the light emitting device has to be disposed close to the generator. there were.

  In addition, it is necessary to turn on the switch of the light emitting device every time the user rides a bicycle, which is troublesome, and he often forgets to turn on the switch.

  Therefore, an object of the present invention is to provide a bicycle mounting light emitting device that has good visibility and can emit light reliably without forgetting to turn on a switch when running a bicycle.

  In order to solve the above-mentioned problem, a bicycle mounting light emitting device according to the present invention according to claim 1 is formed such that a light emitting device main body can be mounted in an air injection hole of a bicycle tire and detects vibration. And emits light.

That is, the light emitting device for mounting a bicycle according to the present invention according to claim 1 is configured to emit light by detecting vibration, so that when the bicycle is run, the light is reliably emitted by the vibration and the bicycle is stopped. When it is made to vibrate, it no longer vibrates, so the light emission disappears.
Further, since the light emitting device body is mounted in the air injection hole of the bicycle tire, the light emitting portion looks like a ring due to an afterimage of the light emitting portion when the wheel rotates.

  According to a second aspect of the present invention, there is provided the bicycle mounting light emitting device, wherein the light emitting device main body is formed as a cap of an air injection hole of the tire.

  That is, in the light emitting device for a bicycle according to the present invention described in claim 2, the cap is unnecessary because the light emitting device main body serves as a cap for the air injection hole portion of the tire. Further, since the light emitting device main body only covers the air injection hole, it is not necessary to process the air injection hole.

  According to a third aspect of the present invention, there is provided a bicycle mounting light emitting device, wherein an LED light emitting element, a vibration detection sensor, and a battery are used in the light emitting device main body.

  That is, in the light emitting device for mounting a bicycle according to the present invention, when the vibration detecting sensor detects the vibration, a current flows from the battery to the LED light emitting device to cause the LED light emitting device to emit light.

  According to a fourth aspect of the present invention, there is provided a bicycle mounting light emitting device, wherein the light emitting device main body is formed as a character.

  That is, the light emitting device for bicycle mounting according to the present invention according to the fourth aspect is formed as a character, so that the light emitting device main body is provided with decorativeness.

  According to a fifth aspect of the present invention, there is provided the bicycle mounting light emitting device, wherein the character forming the light emitting device main body is formed so that a part of the character can swing.

  That is, in the light emitting device for mounting a bicycle according to the present invention according to the fifth aspect of the present invention, a part of the character swings more and more easily vibrates than other parts.

The bicycle light emitting device according to the first aspect of the present invention is configured such that the light emitting device main body can be mounted on the tire valve of the bicycle. Since the afterimage of light emission due to the light emission is continuously recognized in a ring shape, the light emission range is wide and the visibility is very good.
Therefore, the driver of the vehicle can be surely visually recognized, so that a bicycle accident or the like can be reduced.
In addition, because it is configured to emit light by sensing vibration, it emits light reliably due to the vibration when running the bicycle, so there is no need to switch on every time you ride a bicycle like a conventional light emitting device Absent.
In addition, since the user does not forget to turn on the switch, there is no problem of running the bicycle without emitting light from the light emitting device.

  In addition, the light emitting device for mounting on a bicycle according to the present invention according to claim 2 has a screw portion that can be screwed to a screw portion of the tire valve body since the light emitting device body is formed as a cap of the tire valve body. By simply providing, it can be easily mounted, and the structure can be simplified and manufactured at low cost.

In addition, the light emitting device for mounting a bicycle according to the present invention according to the third aspect of the present invention uses the LED light emitting element, so that the cost can be reduced and the emission color can be diversified.
Further, since the vibration detection sensor is used, it is possible to reliably detect the vibration generated by running the bicycle, and to emit light reliably during running.
In addition, since a battery is used, there is no need to use a generator for a headlight, and the arrangement location is not restricted.

  In the light emitting device for mounting a bicycle according to the present invention, since the light emitting device main body is formed as a character, decorative interest can be obtained even when the light is not emitted, and visually enjoyed. be able to. In addition, the demand becomes more familiar to the consumer, and the demand increases.

  Further, in the light emitting device for mounting a bicycle according to the present invention, since a part of the light emitting device main body is formed so as to be able to swing, it is possible to obtain an interesting movement and to obtain the neck of the light emitting device. Vibration can be easily detected by incorporating the above-mentioned vibration detection sensor in a part that swings.
