Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a bicycle back light for reflecting a headlight of an automobile approaching from behind to make bicycle traveling safe at night.

[Conventional technology]

Conventionally, only one tail light made of red reflective glass is fixed to the rear part of the bicycle as a back light for the bicycle, such as a mudguard on the rear wheel. When a vehicle approaches from behind while driving at night, the taillights are reflected by the headlights of the vehicle so that the driver of the vehicle can confirm that the bicycle is traveling ahead. Was there.

[Problems to be solved by the device]

However, since the conventional tail light (bicycle back light) has a structure in which a red reflective glass is fixed, whether the bicycle running in the front is normally driven or is being staggered? , It was difficult for the driver of the car approaching from behind to check the bicycle without approaching the closest distance of about 20 meters.

Therefore, especially when an old man is staggering at night, a contact accident may occur, which is extremely dangerous.

Therefore, the present invention has an object to prevent the occurrence of useless contact accidents by allowing the driver of an automobile approaching from behind to easily confirm the staggering of the bicycle at night, etc.

[Means for Solving the Problems]

In order to achieve the above object, the present invention provides a guide member extending in the left-right direction in a main body case attached to the rear part of a bicycle, and a reflecting member reflecting in a warning color such as red in the left-right direction along the guide member. And a pair of left and right openings for allowing the reflection member to be visually recognized by sandwiching a shield portion capable of concealing the reflection member in a region corresponding to the movement range of the reflection member on the rear surface of the main body case. The gist of the invention is that a reflection part is provided in the main body case that is visible from the rear of the bicycle through each opening and that reflects a caution color such as yellow.

[Action]

That is, when the bicycle leans to the right while the bicycle is running, the reflecting member moves to the opening on the right side along the guide member,
On the contrary, when the bicycle leans to the left, the reflecting member moves to the opening on the left side along the guide member. Then, when the headlight of a car approaching from behind the bicycle hits, the opening on the side where the reflecting member is moving is reflected in a warning color such as red by the reflecting member, and the opening on the opposite side is the inner surface side of the main body case. Reflected in a caution color such as yellow by the reflection part of.
Therefore, when the bicycle is staggered to the left and right, the reflective member repeats reciprocating movement between the left and right openings, so that the left and right openings cause warning colors such as red and caution colors such as yellow. The reflection is repeated alternately.

〔Example〕

An embodiment embodying the present invention will be described below with reference to FIGS.

As shown in FIG. 1, the body case 2 of the bicycle rear light 1 has a flat box shape. As shown in FIG. 3, the main body case 2 has a pair of upper and lower rail members (guide members) 8 having a substantially U-shaped cross section sandwiched between the front plate 6 and the rear plate 7 in parallel. Together with the front plate 6 and the rear plate 7
It is configured by sandwiching a pair of right and left longitudinal members 9 in parallel on both left and right side portions between and. Then, inside the main body case 2, the red reflective glass 12 shown in FIGS.
The two circular reflectors (reflecting members) 3 made of are housed in the groove 8a of the rail member 8 so as to be rollable between the right and left longitudinal members 9. The outer peripheral edge of each circular reflecting plate 3 is provided with an edge 13 made of a metal plate so that the circular reflecting plate 3 can easily roll in the groove 8a.

The rear plate 7 of the body case 2 is separated from the circular reflector 3 by a distance slightly longer than the diameter of the circular reflector 3 in a region corresponding to the moving range of the circular reflector 3 regulated by the right and left longitudinal members 9. A pair of left and right openings 4 are provided. Also, each opening 4
A rim material 15 is fitted in. And both of these openings 4
The rear surface of the rear plate 7 located between them serves as a shield 11 that can conceal the circular reflector 3 from the outside of the body case 2.
Further, the inner surface of the main body case 2 which is visually recognized through each of the openings 4 has a reflective coating which reflects yellow when light is applied.
(Reflecting part) is applied.

On the other hand, the front plate 6 of the main body case 2 has a pair of left and right attachment pieces 5 having a substantially L shape as shown in FIG. Further, each mounting piece 5 is provided with several mounting holes 14 (five in this embodiment). Then, the bicycle warning light 1 is attached to the main body case 2 by the mounting piece 5.
The opening portion 4 is attached to the rear portion of the bicycle B so that the opening portion 4 is on the rear side.

Next, the operation of the bicycle warning light 1 configured as described above will be described.

Now, the fact that the bicycle B is staggering means that the bicycle B is tilted slightly to the left and right alternately. Therefore, as shown in FIG. 6, if the bicycle B, which is being driven by the old man M, is tilted to the left, the two circular reflectors 3 housed in the body case 2 are placed in the groove 8a of the rail member 8. Roll to the left. When the left circular reflector 3 comes into contact with the left longitudinal plate 9, the left circular reflector 3 is visible from the outside through the left opening 4, and the right circular reflector 3 is shielded. It is hidden behind 11 and invisible from outside. Therefore, in this left tilted state, the bicycle B is
When the headlight of the vehicle hits the rear warning light 1 for bicycles from behind, the opening 4 on the left side is provided with the circular reflector 3 on the left side.
Is reflected by the red warning color. On the other hand, the opening 4 on the right side is reflected in yellow by the reflective coating 10 on the inner surface of the main body case 2.

Next, assuming that the bicycle B leans to the right from the left leaning state,
The two circular reflectors 3 housed in the body case 2 roll to the right in the groove 8a of the rail member 8. Therefore, when the right circular reflector 3 hidden behind the shielding portion 11 contacts the right longitudinal plate 9, the right circular reflector 3 is visible from the outside through the right opening 4. At the same time, the circular reflector 3 on the left side is hidden behind the shield 11 and is invisible from the outside. Therefore, when the headlight of the vehicle hits the bicycle rear warning light 1 of the bicycle B from behind in this rightward tilted state, the right side opening 4 is reflected by the circular reflector 3 on the right side in a red warning color. However, the opening 4 on the left side is reflected in yellow by the reflective coating 10 on the inner surface of the main body case 2.

Then, when the staggering operation of the bicycle B is continued thereafter, the two circular reflectors 3 repeatedly move in the left-right direction, so that the two left and right openings 4 alternately reflect red and yellow. Therefore, a driver of an automobile approaching from behind the bicycle B can easily confirm that the bicycle B is being staggered even from a distance by the red and yellow alternating reflections of the openings 4. it can. Therefore, when the driver of the automobile overtakes the bicycle B, he / she can slow down and run over the side of the bicycle B carefully and prevent the occurrence of unnecessary contact accidents.

When either the right side opening 4 or the left side opening 4 of the left and right openings 4 is continuously reflected in red, the bicycle B is in the direction of the red reflected opening 4. It can be a sign that the vehicle is turning right or left, so that the driver of the vehicle can select a safe driving route in advance according to the sign.

In addition, in the above-described embodiment, two circular reflectors 3 are used, but one circular reflector 3 may be used.
In this case, although the reaction time is slightly delayed as compared with the case where two bicycles are used, there is no change in that the bicycle B rolls in the left-right direction in accordance with the swing of the bicycle B. Occurrence can be prevented in advance.

[Effect of device]

As described in detail above, according to the present invention, when the bicycle is staggered, the reflecting member moves in the left-right direction, and the left and right openings alternately reflect the warning color such as red and the caution color such as yellow. Since it repeats, it is possible to easily confirm the staggering of the bicycle at night from the distance to the driver of the car approaching from behind, and it is possible to prevent unnecessary contact accidents from occurring, which is an excellent practical effect. is there.
