Then, when the bicycle is running at night, the driver of a car traveling from the front or the rear of the bicycle is reflected by the light of the headlight of the bicycle or the rear reflector. By recognizing that the bicycle is traveling at a distant position by looking at the light of the headlights and paying attention so as not to pose a danger to this traveling bicycle, It is designed to ensure safety by preventing collisions from the rear.

However, since a bicycle is not generally provided with a device that reflects light from the side direction or emits light in the side direction, such as an automobile running from the side direction with respect to the bicycle. The driver could not recognize this bicycle until he came very close, and as a result, a collision accident or a car accident could occur.

In order to prevent such an accident, a bicycle having a trapezoidal base made of plastic and having a retroreflective material adhered to both sides of the base, and a groove provided on the periphery of the base and capable of being attached to and detached from a spoke of a bicycle wheel. Side reflectors have been proposed. By mounting this bicycle side reflector so that its groove fits into the spoke of the bicycle wheel, the bicycle side reflector reflects light to the driver of the vehicle coming from the side direction, It is intended to signal its presence and prevent the occurrence of accidents.

[0005]

However, in the above-mentioned conventional bicycle side reflector, when the headlight of the bicycle irradiates the retroreflective material with light, the light is retroreflected in the irradiation direction to drive the bicycle. The structure that informs the hand of the existence of the bicycle allows the driver to be informed of the existence of a bicycle traveling at night when the light from the bicycle's headlights does not irradiate the bicycle side reflector even if it is slightly displaced. In this case, there is a possibility that the accident of the car coming from the side direction of the bicycle cannot be reliably prevented.

The present invention solves the above problems, and an object of the present invention is to provide a safety light capable of preventing an accident from the side direction side of a bicycle traveling at night and improving safety. It is what

Embodiments of the present invention will be described below with reference to the drawings. In FIGS. 1 to 4, reference numeral 1 denotes a plastic base formed in a substantially trapezoidal shape, and a groove 5 for engaging with a spoke 4 of a wheel 3 of a bicycle (see FIG. 3) 2 is provided around the base. ing. Then, by inserting the groove portions 5 on both sides of the base body 1 into the spokes 4 of the bicycle 2, the safety lights 10 mainly including the base body 1 are attached to the wheels 3. In addition, a recursive auxiliary reflecting material 6 is attached to both surfaces of the base body 1 which is directed to the side direction of the bicycle 2 with the safety light 10 attached.

A window 7 is provided so as to penetrate both sides in the substantially central portion of the base 1, and a light emitting diode 9 as a light emitting source is formed by an epoxy resin adhesive 8 applied to the peripheral wall 7a of the window 7. Are fixed in the window 7. Then, a reflection plate 11 as a reflection member, which is formed of aluminum foil or the like, is arranged at a position in the window portion 7 that is the main light emission direction of the light emitting diode 9 (upward direction in FIGS. 1, 2, and 4). The reflection plate 11 is arranged at an angle of 45 degrees outward with respect to the main light emitting direction of the light emitting diode 9, and reflects the light a emitted from the light emitting diode 9 as shown in FIG. The bicycle 2 is made to emit light in both directions.

Here, 12 is a battery for a light emitting source which is housed in a recess 13 of the base 1 (see (a) and (b) of FIG. 4) and one lead terminal 9a of the light emitting diode 9 is always in contact. In this coin-type storage battery, the battery lid 14 is arranged so as to cover the storage battery 12. The battery lid 14 is screwed into a screw hole 13a formed in the recess 13 and rotatably arranged, and is also used as a switch. That is, as shown in FIG. 4A, by rotating the battery lid 14 so as to move to the inner side of the screw hole 13a, the other lead terminal 9b of the light emitting diode 9 comes into contact with the storage battery 12. , Light emitting diode 9
, While the battery cover 14 is rotated so as to move to the front side of the screw hole 13a, as shown in FIG. 4B, the other lead terminal of the light emitting diode 9 is turned on. 9b is separated from the storage battery 12 by its elasticity, and the light emitting diode 9 is turned off.

In the above structure, the safety light 10 is attached to the spokes 4 of the bicycle 2 by the groove 5 thereof, so that the light a from the light emitting diode 9 is reflected by the reflector 11 as shown in FIG. After being reflected in both side directions, light a is emitted from the bicycle side safety light 1 itself in both side directions. As a result, a driver of an automobile traveling on both sides of the bicycle 2 can recognize that the bicycle 2 is traveling by looking at the light a emitted from the safety lamp 10.

Moreover, since the safety light 10 rotates while moving as the bicycle 2 runs, the trajectory of the light a emitted from the safety light 10 draws a cycloid curve. Therefore, an automobile driver or the like may use this peculiar light a.
Of the bicycle 2 can be easily recognized, and as a result, the occurrence of an accident can be prevented.

The auxiliary reflectors 6 provided on both sides of the base 1 also reflect light from the automobile or the like, so that the driver of the automobile or the like can recognize it more reliably. Further, even if the storage battery 12 is consumed with electricity and the light a cannot be emitted from the light emitting diode 9, the auxiliary reflector 6 reflects the light, so that the driver of the vehicle or the like recognizes it. It becomes possible to secure safety.

A through hole 15 is provided at an appropriate position of the base 1, and the safety lamp 10 is used as a tail lamp of the bicycle 2 by locking the safety lamp 10 at the rear portion of the bicycle 2 through a string or the like. You can also do it. Also, when walking or jogging at night, the through hole 1
It can be attached to clothes, hats, school bags, etc. by using 5 and it will be a real benefit for traffic safety. In this case, if a blinking function is added to further improve the attractiveness,
Further, the safety is conspicuously improved.

An experiment was carried out in which the safety light 10 was attached to the bicycle 2 and was lit at night for running. As a result, a bright red color was obtained with the light emitting point (the reflector 11 and the light emitting diode 9) of the safety light 10 as the moving point. A locus consisting of a cycloid curve of light was drawn, and it was possible to clearly confirm the existence of the moving bicycle 2 from a distance of about 50 m within a visual field of about 60 degrees in both sides of the bicycle 2.

Further, since the safety lamp 10 has a simple structure composed of the reflector 11 and only one light emitting diode 9 which is the minimum number, it has a function of guiding the optical path to both sides of the bicycle 2. It is economical, because it has the advantages that it can be manufactured at a low cost, and that it consumes a small amount of electric power, while it is economical and contributes significantly to traffic safety.

Next, FIGS. 5 and 6 are perspective views showing a safety lamp according to another embodiment of the present invention.

It has been inserted.

Then, as shown in FIG. 7A, the reflecting member 2 is positioned so that the top portion 22b of the light emitting diode 9 in the window portion 7 is located in the main light emitting direction (directly above in FIG. 7).
2 is arranged, the light a
Is divided into two and emitted to the left and right sides of the bicycle 2, and as shown in FIG. 7B, the top 22b of the window 7 is reflected from the main light emitting direction of the light emitting diode 9. By arranging the member 22, the light a is emitted only in one side direction of the bicycle 2 without being divided into two by the one reflecting plate 21 alone.

According to this safety lamp 20, as shown in FIG. 7B, by sliding the reflecting member 22 in the direction along the side direction of the bicycle 2, strong light a is emitted only in one side direction. Therefore, when the position where the automobile 2 or the like travels is only in one side direction,
For example, when driving along the coastline, it becomes easier for the driver of the car to recognize,
Further, the safety will be improved.

In this case, the case where the reflecting member 22 is slid in the side direction of the bicycle 2 has been described.
Instead of the reflecting member 22, the light emitting diode 9 side may be slid.

In the above embodiment, the safety light 1
0,20 as a whole may be stored in a transparent film back for waterproofing and mounted on the spokes 4 of the wheels 3 of the bicycle 2,
According to this structure, it can be used without trouble even in the case of rain at night, and dust can be prevented from entering the inside. When the safety lights 10 and 20 were attached to the spokes 4 and an experiment was carried out at night in rainy weather, good visibility almost the same as in clear weather was obtained.

In the above embodiment, the base 1
Inside, the light emitting diode 9, the storage battery 12, and the reflector 11
Although the case where the above is provided is illustrated, the present invention is not limited to this, and the light emitting diode 9, the storage battery 12, the reflection plate 11, and the like may be provided outside the substrate 1.

Instead of this, a phosphorescent film or a fluorescent film may be used. In addition, in the above-described embodiment, the case where the storage battery 12 is used as the light-emitting source battery is described, and if this structure is adopted, charging can be performed many times.
Although there is an advantage that the safety lights 10 and 20 can be used for a long period of time, it is needless to say that general batteries may be used without being limited to this.

Further, in the above embodiment, the groove portion 5
Although the case where the spokes 4 are engaged with the spokes 4 of the wheels 3 of the bicycle 2 has been described above, the present invention is not limited to this, and the hooks may be configured to be engaged.
Any structure may be used as long as it has an engaging portion capable of engaging with.

FIG. 8 is a front view showing a safety light according to another embodiment of the present invention. In addition, the above safety light 10
Those having the same function as are denoted by the same reference numerals, and the description thereof will be omitted. As shown in FIG. 8, in the safety lamp 30, a mercury switch 31 as a switch means is arranged inside the base body 1, and the mercury switch 31 is directly or indirectly connected to the light emitting diode 9. . In this mercury switch 31, the longitudinal direction of a glass cell 31b in which a lump of mercury 31a is enclosed is along the radial direction of the wheel 3, and the electrode 31c of the mercury switch 31 is on the outer peripheral side of the wheel 3. It is mounted so that it is located.

The safety light 30 also moves while rotating integrally with the wheels 3 as the bicycle 2 runs. In this case,
When the bicycle 2 runs at high speed and the wheels 3 rotate at high speed,
The centrifugal force causes the mercury block 31a of the mercury switch 31 to move the electrode 3
Since the mercury switch 31 is always turned on by contacting the 1c, the trajectory of the light a emitted from the safety lamp 30 draws a continuous cycloid curve. On the other hand, when the bicycle 2 is driven at a low speed and the wheels 3 rotate at a low speed, the centrifugal force is small and the mercury lump 31a comes into contact with the electrode 31c only when the electrode 31c of the mercury switch 31 is positioned below due to the gravity. . That is, the mercury switch 31 is turned on only when the safety light 30 is located on the lower side of the wheel 3, and the locus of the light a emitted from the safety light 30 blinks with the rotation of the wheel 3 and has a broken line shape. Draw a discontinuous cycloid curve of.

Therefore, as described above, the mercury switch 31
According to the safety light 30 provided with, the movement of the light a becomes more peculiar, the visibility for the driver of the automobile can be further enhanced, and the power saving is performed when the mercury switch 31 is in the OFF state. Therefore, the life of the light emitting battery can be extended.

It should be noted that those having the same functions as those of the safety lamp 10 described above are designated by the same reference numerals, and the description thereof will be omitted.

As shown in FIG. 9, in the safety lamp 40, the brightness detecting means which detects the external brightness through the brightness detecting window 41a and is turned on when the external brightness becomes a predetermined value or less. An optical sensor circuit 41 as a component and a vibration switch 42 which is composed of a vibration spring or the like and is intermittently connected by vibration are disposed inside the base body 1. As shown in FIG. 10, the optical sensor circuit 41 and the vibration switch 42 are provided. And are electrically connected between the light emitting diode 9 and the storage battery 12.

According to the safety lamp 40, the light emitting diode 9 blinks only when the brightness of the surroundings becomes dark and the bicycle 2 is driven and vibrates at night. As a result, the light emitting diode 9 blinks randomly according to the random vibration of the bicycle 2, and the visibility for the driver of the automobile is improved. In addition, since the light emitting diode 9 blinks only when it becomes dark and the bicycle 2 is driven, it is not necessary to operate the battery cover 14 as a power switch, and the storage battery 12 is in an over-discharged state due to forgetting to turn off the switch. Therefore, there is no fear that the life of the storage battery 12 will be shortened, and the life of batteries such as the storage battery 12 can be extended.

The above electric circuit is turned on and off a plurality of times by, for example, one contact operation of the vibration switch 42.

As a result, as long as the switch means is set to the ON state, the blinking lighting operation is performed at regular time intervals without depending on the rotation speed of the wheels 3 of the bicycle 2 or relating to the presence or absence of vibration. That is, the light-emitting diode 9 blinks not only when the vehicle is running but also when the vehicle is stopped, which allows the driver of the vehicle to be ventilated in all circumstances and is constantly lit. Power consumption can be reduced compared to the above, and the life of batteries such as the storage battery 12 can be extended.

It should be noted that, instead of separately providing the light emitting diode 9 and the blinking circuit 51 as described above, the same effect can be obtained by using a light emitting diode having a built-in blinking circuit.

FIGS. 13 (a) and 13 (b) are a front view and a side sectional view showing a safety light according to another embodiment of the present invention. It should be noted that those having the same functions as those of the safety lamp 10 described above are designated by the same reference numerals, and the description thereof will be omitted.

In addition to the two light emitting diodes 9, a switch 64, a blinking circuit 51, a storage battery 12 and the like are built in the base 61.

In this structure, when the switch 64 is set to the ON state, the two light emitting diodes 9 blink and light at predetermined time intervals. In this case, since the light from each light emitting diode 9 is directly emitted to both sides of the bicycle 2 without using a reflecting member, one light emitting diode 9
Higher brightness can be obtained and the attractiveness to the driver of the automobile can be improved as compared with the case where the light from is dispersed in two directions. Further, as in the above-described embodiment, the light emitting diode 9 blinks not only when the vehicle is running but also when the vehicle is stopped, so that the driver of the vehicle can be alerted under all circumstances. Also,
The power consumption can be reduced as compared with the case where the light is constantly turned on, and the life of batteries such as the storage battery 12 can be extended. Further, by arranging the light emitting diodes 9 so as to face each other so that the rear side of the light emitting diode 9 also faces the window portion 62 of the base 61, the light from the rear side of the light emitting diode 9 is also used to emit light. It is possible,
The brightness can be further increased.

As described above, instead of incorporating the light emitting diode 9, the switch 64, the blinking circuit 51, the storage battery 12, etc. in the base 61, (a) and (b) of FIG. 14 are used.
As shown in FIG. 5, a base 71 having grooves 5 to be fitted into the spokes 4 of the bicycle 2 is formed of a simple plate-like body, and the base 71 includes a light emitting diode 9, a switch 64, a blinking circuit 51, a storage battery 12, and the like. Even if the box 72 is fixed and the safety lamp 70 is configured, the same effect can be obtained. Further, such a structure has the above-described safety lamps 10 and 2.
It may be applied to 0, 30, 40, 50, 60.
