Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a bicycle lighting device that is attached to a front hawk of a bicycle and illuminates a road surface when the bicycle is running, and in particular, a bicycle lighting having an improved mounting portion for the front hawk. Regarding the device.

(Prior Art) As shown in FIG. 2, a conventional bicycle lighting device includes a dynamo 1, a headlamp 2 connected to the front of the dynamo 1, and a spring-type raising / lowering device 3 connected to the rear of the dynamo 1. , The mounting bracket 4 extending from the tilting device 3,
To the arm 6 provided on the front hawk 5 of the bicycle with bolts 7
It is stuck in.

Therefore, when driving at night, when the lever 8 of the tilting device 3 is pushed down, the dynamo 1 rotates by a predetermined angle and the roller 9 at the upper end contacts the front wheel (not shown) of the bicycle, and the roller 9 rotates together with the front wheel. By doing so, the headlight 2 is turned on.

(Problems to be solved by the invention) However, in the conventional lighting device, it is necessary to previously provide the arm 6 on the front hawk 5 of the bicycle, and when the arm 6 of this type is not provided as in a high-end sports car. Must procure separate parts each time. Further, in the device of FIG. 2, since the center of gravity is at the front, the lighting device is likely to rotate, it takes a lot of time to install, and there is a possibility that the lighting device may tilt forward and downward while the bicycle is running. Further, in the conventional device, since the mounting bracket 4, the bolt 7 and the like are exposed, there is a drawback that the appearance of the entire bicycle is deteriorated.

The present invention has been made in view of such circumstances, and an object thereof is to be able to be firmly attached to a front hawk of a bicycle without an arm, and to be vibrated even while traveling, and to be even more attractive. (EN) Provided is a bicycle lighting device which does not deteriorate.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a bicycle lighting device including a headlight, a dynamo, and a dynamo tilting device. It is characterized in that a clamp for holding the hawk is fixed, a headlight is arranged in front of the tilting device, and a dynamo is arranged in the rear.

(Operation) With this configuration, the entire lighting device is firmly attached by simply fitting the housing clamp to the front fork of the bicycle and tightening it, and the headlamp and dynamo are fixed in a well-balanced front and rear direction around the housing. It

(Embodiment) FIG. 1, FIG. 3 and FIG. 4 are a side view, a plan view and an exploded perspective view of a bicycle lighting device to which the present invention is applied, respectively.
The same parts as those of the conventional device are denoted by the same reference numerals, and the right side in the drawing is the front.

This bicycle lighting device (hereinafter simply referred to as lighting device)
Then, the headlight 2 is in front of the tilting device 3, and the dynamo 1 is in the rear.
And a U-shaped housing for accommodating the tilting device 3
A clamp 11 is provided on the back surface of 10 (FIG. 3).

The dynamo 1 generates electric power by the upper cap type roller 9 rotating in contact with the rim (not shown) of the front wheel of the bicycle. In this embodiment, a rim contact type dynamo is used from the viewpoint of appearance, but a tire contact type dynamo can be used as shown in FIG.

As shown in FIG. 4, the raising / lowering device 3 is composed of a housing 10, a coil spring 18, a pin 19, a support shaft 20, a lever 8, a lever coil spring 21 and a removable cover 12.

The housing 10 is U-shaped and has a pair of holes 22 formed on both sides, and the shaft 1a of the dynamo 1 is rotatably inserted and supported in the holes 22. A coil spring 18 for biasing the dynamo 1 toward the front wheel is wound around the shaft 1a, and one end of the coil spring 18 is attached to the housing 10a.
The other end is locked to the pin 19 inserted in the hole of the shaft 1a. The housing 10 is further provided with a pair of small holes 23, and the spindle 20 is inserted and supported in the small holes 23. The lever 8 and a lever coil spring 21 are fitted on the support shaft 20, and the lever 8 is biased upward by the coil spring 21.

Therefore, the dynamo 1 is biased clockwise in FIG. 4, that is, to the front wheel side by the coil spring 18, but normally the end of the pin 19 is locked by the lever 18 and is prevented from rotating. However, when the lever 8 is pushed downward, the engagement with the pin 19 is released, and the dynamo 1 rotates about the shaft 1a by the urging force,
The roller 9 contacts the rim of the front wheel.

A clamp 11 is fixed to the rear surface of the housing 10 by two rivets 24, and the clamp 11 is composed of a curved fixed arm 13 and a movable arm 14 and a tightening bolt 15. The rear end of the movable arm 14 is rotatably attached to the fixed arm 13, and the tips of both arms 13 and 14 are bolts 1.
It is possible to adjust the tightening with 5.

The support arm 16 is forward from the fixed arm 13 (right side in the figure).
The headlamp 2 is attached to the support arm 16 with a screw 17.

Therefore, if the clamp 11 is fitted to the front hawk 5 of the bicycle as shown by the phantom line in FIG. 3 and the bolt 9 is tightened at a position where the roller 9 of the dynamo 1 can contact the rim, the lighting device is fixed. It At this time, the mounting arm 6 (FIG. 2) on the front fork side, which is required in the prior art, is not necessary, and the clamping force of the clamp type clamp 11 increases the fixing force of the lighting device.

Further, since the clamp 11 is provided on the back surface of the housing 10, the mounting location of the lighting device is difficult to see from the outside, and the appearance is neat. Further, the use of the rim contact type dynamo 1 and the cover 12 covering the raising and lowering device 3 is also useful for improving the appearance.

When the bicycle is traveled at night, when the lever 8 is pushed down, the roller 9 of the dynamo 1 is brought into contact with the rim of the front wheel by the tilting device 3, and when traveling in this state, the headlight 2 is turned on to illuminate the road surface. Since the dynamo 1 and the headlight 2 are arranged in a well-balanced manner around the housing 10 of the tilting device 3, the lighting device will not be tilted or displaced due to vibration during traveling.

(Effect of the Invention) As described in detail above, in the bicycle lighting device of the present invention,
A clamp for holding the front hawk of the bicycle is fixed to the back of the housing of the tilting device, and a headlight is placed in front of the tilting device and a dynamo is placed behind the tilting device. It can be installed firmly,
By arranging the headlight and the dynamo in a well-balanced manner, it is possible to prevent the lighting device from tilting due to vibration during traveling of the bicycle.
