Description

[Detailed Description of the Invention] This invention relates to a direction indicator for a bicycle, and more specifically to a direction indicator for a bicycle that can also serve as a vehicle width indicator.

Due to the structure of a bicycle, the width of the rear part is about the width of a saddle, and the front part is slightly wider than the shoulder width of the rider. When driving at night, when the sense of distance is impaired, the headlights and taillights are only placed in the center of the width, indicating the direction of travel and the effective width of the bicycle for vehicles and other vehicles running parallel to or facing each other. There is no effective means to do so.

Therefore, when a bicycle rides parallel to or facing a large vehicle such as a car on a general road without a dedicated bicycle lane, the bicycle's body or the body of the person riding the bicycle may be There is a high risk that some parts may come into contact with the vehicle or others.

In such a case, there is a high risk that the driver may lose his balance and fall, or the driver may lose control and fall onto the road shoulder or under the road, or the driver may approach the side of the vehicle and be run over by the rear wheel, causing a serious accident. Many bicycle accidents have been reported to occur at night under such conditions.

This invention aims to eliminate the above-mentioned drawbacks, and its features are that the indicator mounting member is attached to the part of the bicycle handlebar next to the grip, and the hinge component of the member is attached to the handlebar of the bicycle. A stopper is provided on the hinge component, and a plurality of elongated direction indicating pieces are pivotally attached to the hinge component so that the rotation angle can be changed by engagement with the stopper, and each indicating piece... To provide a simple direction indicator for a bicycle which is configured to project in a V-shape or fan-shape.

An embodiment of this invention shown in the drawings will be described in detail below.

Figure 1 is an exploded perspective view of the turn signal of this invention. 1 is a thin metal plate with both ends thereof extending outward in parallel, and between them a ring with a diameter equal to or slightly smaller than the diameter of the handle pipe. The attachment band portion 2 processed into a shape and the overhang portion 3
A and 3b have a hole 4 in one side and a screw hole 5 in the other into which a tightening screw (to be described later) can be screwed, and further extend to one side of the overhang 3a and be bent at right angles thereto. A pair of stoppers 6a are bent into an L shape and extend on both sides.
, 6b, and is a mounting member consisting of a hinge component piece 8 having a through hole I in the center.

Reference numeral 9 has an indicator piece 10 made of a synthetic resin material added with a luminous pigment or a light retroreflection film, and a notch 12a in a hinge component piece 11 at one end of the indicator piece 10 that abuts against the stoppers 6a and 6b.

12b (FIGS. 5 and 6), both the members 1 and 9 are through holes 7 and 1 of the hinge components 8 and 11.
3 with spring washer 14. The bolt 17 is inserted through the button washer 15 and the spring washer 16, and the nut 18 is screwed on, thereby forming a pivot for both hinges.

A plurality of direction indicators 19a configured in this way.

19b is the bicycle 20 as shown in FIGS. 2 to 5.
It is mounted near the left and right grips of the handle 21 using the mounting band 2 and tightening screws 22.

It should be noted that the above-mentioned indicator piece 10 can be made more easily visible during the daytime and at night if it is colored so that it can be easily distinguished from the light of a street lamp or the like, for example, the color of the luminous pigment is yellow.

Next, in actual use, when driving straight during the day, the two-way indicators 19a and 19b have their indicator pieces 10 side connected to the bundle 21.
It is directed toward the bundle shaft side of the
When making a right turn as shown in the figure, hold the indicating mechanism 90 part of the direction indicator 19a attached near the right grip of the steering wheel 21 and use the hinge with the bolt 17 as the pivot. By rotating the constituent piece 11 clockwise at 1, where one side faces the stopper, the rotation angle varies depending on the size or presence or absence of the notch in the indicator piece, so the width of the bundle can be moved outward as if opening a fan. It can be made to stick out, indicating to drivers of vehicles running parallel to each other or facing each other that they are intending to turn right, making them clearly aware of the intention and alerting them.

Then, when you finish turning right, you can put it back to its original position and store it like a closed fan.
Direction indicator 1 installed near the left grip of
9b may be rotated counterclockwise in the same manner as described above.

Further, at night, the indicator piece emits light upon receiving light from the outside by the light retroreflection member 10a, so identification is easy as in the daytime.

Next, to use this turn signal as a vehicle display, rotate both turn signals 19a and 19b counterclockwise so that they both protrude outward from the bundle, so that both signs are parallel to the vehicle width. Alternatively, it can be recognized by the button of a vehicle following or facing the other.

In particular, this invention has a simple structure and is therefore easy to operate even by young people.

If the bicycle rider's foot hits the indicator when installing the direction indicator, this can be resolved by slightly increasing the height of the bundle, so that even if something comes into contact with the indicator piece 10, the tip will be rounded. Since the indicator piece itself is elastic, it absorbs the impact caused by bending and coming into contact with it, and there is no risk of damaging the other person.

As mentioned above, this idea is based on bicycle 20.
Attach the indicator mounting member 1 to the part adjacent to the grip of the member 1, and attach the stoppers 6a, 6 to the hinge component 8 of the member 1.
b, and a plurality of elongated direction indicating pieces 10 are pivotally attached to the hinge component piece 8 so that the rotation angle υ changes by engagement with the stopper, and each indicating piece is attached to the bundle width outwardly by V. Since the structure is configured so that it can protrude in a shape or a fan shape, there are a plurality of direction indicator pieces 10 on both the left and right sides of the bicycle handle, and the rotation angle is variable, so it can be made into a V shape or a fan shape, attracting people's attention. to achieve the purpose of direction indication, and a plurality of direction indication pieces 1 are attached to the hinge component 8 of the indication piece mounting member 1.
0 is pivotally mounted so that it can be rotated, so the mounting of the indicator piece is highly flexible, and even if something else touches it, it will not cause any damage to yourself or others.

Also, when not in use, as shown in Figure 2, the bundle 21
Since the plurality of indicator pieces 19b can be superimposed and disposed near the left side of the indicator and do not get in the way, there is an advantage that a storage box is not required.
