Description

[Detailed Description of the Invention] The present invention relates to a bicycle lighting device, and particularly to one in which a bicycle generator and a headlamp are integrated.

Conventionally, this type of lighting device had a pivot attached to the main body case of the generator, and a headlight was attached to this pivot. This led to an increase in costs.

The present invention improves the above-mentioned drawbacks by using the conventional bicycle generator and headlight as they are.The bicycle lighting device of the present invention will be explained below based on the embodiment shown in the drawings.

Reference numeral 1 designates a bicycle generator, which includes an upper case 5 housing a power generation mechanism 4 consisting of a power generation coil 2 and a field magnet 3, and a resin lower case 6 that closes a lower opening of the upper case 5.
It has a rotation drive roller 1.

Reference numeral 8 denotes a bush-type output terminal protruding from the bottom surface 6' of the lower case 6, and a lead plate 1σ is fixed to the lower case 6 and connected to the generator coil 2 via an output extraction mechanism 9; It consists of a resin push button 11 that covers this lead plate 10 and a spring material 12 that constantly presses this push button 11 downward. 11' and the insertion hole 10' of the lead plate 10 are aligned with each other.

One end of the lead wire is passed through 11', and the generated output is taken out to the outside of the generator.

Reference numeral 13 denotes a headlamp incorporating a light bulb (not shown), which has a mounting tab 15 protruding from the lower part of the rear case 14 and a lead wire 16 connected to one terminal of the light bulb.

Reference numeral 17 denotes a support fitting that connects the generator 1 and the headlamp 13, one end of which is bent at a right angle and a mounting hole 18' is drilled to form a mounting portion 18 to which the mounting tab 15 of the headlamp 13 is attached. , the other end is connected to the bottom surface 6' of the lower case 6 of the generator 1.
It has a fixing surface 19 that fixes to.

A through hole 20 passing through the output terminal 8 is provided at a portion of the fixing surface 19 facing the output terminal 8, and a grounding screw hole 22 is provided at a portion facing the bearing 21 of the power generation mechanism 4 in the generator. , respectively, and screw holes 23 for fixing to the bottom of the lower case 6 and 6' are also drilled.

Then, by inserting the headlamp mounting screw 24 into the shaft support hole 15' of the mounting lug 15 and the mounting hole 18' of the support metal fitting 17 and tightening and fixing it with the nut 25, the headlamp 13 is attached to the support metal fitting. 17, and while the output terminal 8 is passed through the through hole 20 and the fixing surface 19 is in close contact with the bottom surface 6' of the lower case 6, the screw 26 is inserted through the fixing screw hole 23 into the lower case 6. and fix this support fitting 17 to the bottom surface 6' of the lower case 6 of the bicycle generator 1, and screw the grounding screw 27 through the lower case 6 from the grounding screw hole 22 to the bearing 21. At least ground the support fitting 17 and the bearing 21, and then connect the headlight 13.
Insert the lead wire 16 into the insertion hole 11' of the output terminal 8 of the generator 1.
and the insertion hole 10' are crimped and held together to integrate the whole.

The bicycle lighting device of the present invention is as described above, and in particular, the bicycle generator and the headlamp are connected through a support metal fitting, and one end of this support metal fitting is connected to the mounting ear piece of the headlamp. The other end is used as a mounting surface to be attached, and the other end is a fixed surface fixed to the bottom surface of the lower case of the generator, and this fixed surface is provided with a through hole that passes through an output terminal provided on the bottom surface of the lower case. Therefore, conventional bicycle generators and headlights can be used, and no special bicycle generator is required.

Furthermore, according to the present invention, since the support metal fitting has a hole for passing the output terminal through, the fixing surface of the support metal fitting can be completely attached to the bottom surface of the lower case of the bicycle generator. Since it can be firmly fixed to the generator, the support bracket will not come off from the bicycle generator even due to vibration during use, improving durability, and it is very easy to intercept the support bracket itself, which is different from conventional bicycle generators. Coupled with the use of bicycle generators and headlamps from
