Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a bicycle lighting device, and more particularly to a bicycle lighting device in which a dynamo and a headlight are integrated.

[Conventional technology]

As a conventional bicycle lighting device of this type, for example, one disclosed in Japanese Utility Model Laid-Open No. 1-116789 is known.

This device employs a configuration in which the entire device is covered with a cover in order to make the appearance look integral.

[Problems to be solved by the device]

However, in this conventional device, the cover is not configured to move integrally with the dynamo, so the cover does not follow up and down of the dynamo, and when the dynamo is up and down, the rotating roller largely separates from the cover, and the mudguard effect There is a problem that it will be halved. Further, since the periphery of the headlight is also covered with the cover, a step is generated between the headlight and the cover, the size of the entire apparatus is increased, and the aperture of the front lens cannot be effectively used.

SUMMARY OF THE INVENTION An object of the present invention is to provide a bicycle lighting device capable of following a headlight and a cover, which has an external appearance and a sense of unity, when the dynamo is tilted.

[Means for Solving the Problems]

The bicycle lighting device according to the present invention comprises a headlight, a dynamo held by a holder so as to be pivotally displaced, and a cover fixedly mounted on the dynamo to which the headlight is attached. In the bicycle lighting device, the cover is a substantially cylindrical first cover that covers from substantially the upper part to the lower part of the dynamo, and is fixed to the headlight and extends in a direction substantially orthogonal to the axis of the first cover. The second cover is formed into a notch on the side of the upper surface of the first cover that faces the tire, and the second cover has a substantially U-shaped cross section and a lower side surface of the first cover. And a bottom surface, and a first U-shaped portion in which a notch for inserting the first cover is opened in the upper and lower portions, and a first U-shaped portion having a substantially U-shaped cross section to cover the upper side of the holder. Two
And a U-shaped portion, and is fixed to the holder via an arc-shaped stay arranged so as to face the first U-shaped portion.

[Action]

According to the above-mentioned means, the cover is divided into the first cover that covers the dynamo and the second cover that is fixed to the headlight to support the first cover and covers the holder. With the two covers, it is possible to configure a cover that has a sense of unity with the headlights in appearance, and moreover, the first cover can follow the dynamo according to the up and down movement of the dynamo.

〔Example〕

1 is an exploded perspective view showing a bicycle lighting device according to an embodiment of the present invention, FIG. 2 is an assembled perspective view thereof, FIG. 3 is a sectional view of a main part of a cover, FIG. 4 is a right side view, Figure 5 is a rear view,
FIG. 6 is a left side view and FIG. 7 is a plan view.

In this embodiment, the bicycle lighting device is a headlight 1.
And a cover 2, a dynamo 3 and a holder 4, and the cover 2 is integrally fixed to the back side of the headlight 1,
The dynamo 3 is held by the holder 4 so as to be pivotally displaced. That is, the shaft 6 protruding rearward in the direction perpendicular to the body portion 5 of the dynamo 3 is rotatably supported by the holder 4 by the urging force of a torsion spring (not shown), and the body portion 5 has The holder 4 is pivotally displaced and held so that it can be pressed against the side surface of the tire (not shown) of the bicycle.

The cover 2 is divided into a first cover 7 and a second cover 8. The first cover 7 is formed in a cylindrical shape having an inner diameter substantially equal to that of the body portion 5 of the dynamo 3, and covers the dynamo 3 from approximately the upper portion to the lower portion. First cover 7
A notch 10 is formed on the upper side of the above, exposing a part of the rotating roller 9 on the side facing the tire. First cover 7
A claw 11 is formed on the lower side of the claw 11. When the first cover 7 is attached to the body part 5 of the dynamo 3, the claw 11 presses the body part 5 and the first cover 7 comes off from the body part 5. Is prevented.

The second cover 8 extends along a direction orthogonal to the axis of the first cover 7, and has a base 12 fixed to the back surface of the headlight 1 and a first U-shaped member having a substantially U-shaped cross section. It is composed of a character-shaped portion 13, a second U-shaped portion 14, and a substantially arcuate stay 15. The first U-shaped portion 13 is formed so as to cover the lower side surface and the bottom surface of the first cover 7, and semicircular cutout portions 16 and 17 for inserting the first cover are opened in the upper and lower portions thereof, respectively. Has been done. Further, the notches 16 and 17 have the same shape as the first cover 7 even when the first cover 7 is tilted up and down together with the dynamo 3.
The gap with the cover 7 is kept at the same size. The second U-shaped portion 14 covers the upper side of the holder 4, and is formed so as to maintain a gap between the holder 4 and the holder 4 even when the headlight 1 tilts. Has been done. One end of the stay 15 is fixed to the base 12 by a screw member 18, and the other end is fixed to the holder 4 by a screw member 19. The adjustment of the vertical irradiation angle of the headlight 1 is performed by using the screw member 18 as a second adjustment.
By moving the cover 8 up and down with respect to the stay 15,
It can be carried out. By the way, in the case of a bicycle lighting device, it is customary that adjustment of the horizontal illumination angle of the headlight 1 is not necessary.

A terminal 20 for connecting the lead wire is provided on the lower surface of the dynamo 3 so that the lead wire 21 connected to the terminal 20
Is inserted into the headlight 1 and connected to the positive terminal of the electric circuit. With the lead wire 21 and the stay 15, the dynamo 3 and the headlight 1 form a closed circuit.

According to this embodiment, the second cover 8 is extended on the back side of the headlight 1, the first cover 7 is attached to the outer periphery of the dynamo 3, and the first cover 7 and the second cover 8 are externally provided. Since it can be seen as one cover 2, the headlight 1 and the dynamo 3 can have a sense of unity. Moreover, even when the dynamo 3 is tilted, the first cover 7 follows the tilting of the dynamo 3, so that the prevention of mud fitting of the rotating roller 9 is not impaired.

Further, since the gap between the first cover 7 and the second cover 8 can be kept constant when the dynamo 3 is tilted, the dynamo 3
It is possible to secure a sense of unity before and after tilting. Further, even if the vertical irradiation angle of the headlight 1 is adjusted, the gap between the holder 4 and the second cover 8 can be sufficiently maintained, so that a sense of unity can be secured.

Since it is not necessary to cover the periphery of the headlight 1 with the cover, the outer frame of the headlight 1 and the front lens can be configured to have the same size, and it is possible to prevent the outer shape of the headlight portion from increasing. While you can
The diameter of the front lens can be effectively utilized.

[Effect of device]

As described above, according to the present invention, the cover fixed to the headlight includes the first cover that covers the dynamo and the second cover that extends on the back surface of the headlight and covers the bottom side of the first cover. Since it is divided, it is possible to configure a cover that has a one-dimensional appearance with the headlight, and moreover, it is possible to reliably prevent spattering due to the rotation of the rotating roller when the tire is in contact.
