【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 1, the direction indicator light of the bicycle according to the present invention is mounted on the power switch portion 11 attached to the handle portion 22 of the bicycle 21 and the avoidance portion 24 of the rear wheel 23 of the bicycle 21. The direction indicator body 1 is made up of a control circuit board 3 and a plurality of LEDs 4 sealed in a casing 2 made of colored vinyl chloride or the like as shown in FIGS. It is attached by a screw 8 to a mounting member 6 which is fixed by a screw 7 to a drop-out avoidance portion 24 of a rear wheel 23 of 21. Then, a diffuse reflection plate 5 is attached to the surface of the casing 2 facing the plurality of LEDs 4.

As shown in FIG. 4, the power switch unit 11 includes a power switch 13 (push button type in this embodiment) for turning the power on and off and a right / left turn switch 15 (sliding type in this embodiment). The casing 12 has a dry battery 16 as an operating power source contained therein, and the casing 12 is attached to a handle portion 22 of a bicycle 21 by a band 17. Further, the casing 12 is provided with a power supply indicator light 14 for indicating the operating state of the power supply. The body 1 of the turn signal lamp and the power switch unit 11 are connected by wire with the vehicle body as the ground.

The plurality of LEDs 4 housed in the casing 2 of the turn signal lamp body 1 are the LEDs 4a, 4b1 and 4c1 in the central portion as tail lights and the LEDs 4c and 4b in the left and right regions for right turn display and left turn display. It is divided into In this embodiment, there are four tail lights and six for turning left and right. In this example, the LEDs 4b1 and 4c1 serve both as a tail light and as a left / right display.

Next, an example of its use will be described. First, the power switch 13 of the power switch unit 11 is turned on. As a result, the power supply indicator light 14 lights up, and it is confirmed that the dry battery 16 which is the power supply is normal (when the power supply indicator light 14 does not light up, replace the dry battery 16) and the central portion of the direction indicator light body 1. LEDs 4a, 4b1 and 4c1 of the LED light up and serve as tail lights. (Fig. 5)

When making a right turn, the right / left turn switch 15 is slid to the right with the power switch 13 turned on (arrow r in FIG. 4). As a result, the LED 4c in the left area of the direction indicator lamp body 1 intermittently blinks in the direction of arrow R, that is, in the order of 4c3, 4c2 and 4c1, as shown in FIG. Then, the LED 4b in the right region intermittently blinks in the order of 4b1, 4b2, 4b3. After the right turn, the right / left turn switch 15 is returned to the center, and the blinking of the LEDs 4c, 4b in the left and right regions of the turn signal lamp body 1 is stopped.

When a further left turn is to be made, the right / left turn switch 15 is slid to the left (arrow l in FIG. 4) in the same procedure as above to turn off the LED 4b in the right area of the turn signal lamp body 1. The blinking of the LED 4b in the right area at this time is intermittently performed in the direction of arrow L, that is, in the order of 4b3, 4b2, 4b1 as shown in FIG. Then, the LED in the left area blinks in the order of 4c1, 4c2, 4c3. After the left turn is completed, the right / left turn switch 15 is returned to the center, and the blinking of the LEDs in the left and right regions of the turn signal lamp body 1 is stopped.

By performing the above operation every time the vehicle turns right or left, it is possible to inform the driver of the automobile behind the bicycle 21 of the existence of the bicycle 21 and display the intention of the bicycle 21. As described above, the indications for right and left turns can be identified by the LEDs that blink sequentially from the right or the left, so even if the bicycle 21 has a narrow vehicle width, it can be seen from the far right. The left turn can be identified.

Further, since the diffuse reflection plate 5 is attached to the inside of the casing 2 of the direction indicator main body 1, even if the tail lights (LEDs 4a, 4b1 and 4c1 in the central area) are forgotten to be turned on, the presence of a bicycle from a distance. Can be notified to the car driver. In this embodiment, the diffuse reflection plate 5 is attached, but the diffuse reflection portion 9 may be directly formed in the casing 2 by laser cutting or the like. Thus, in the above example, the direction indicator main body 1 is attached to the avoiding slot 24, but it may be attached to a slightly upper portion, for example, the rear portion of the saddle.
