JP2000133015A - Rotatable headlight for bicycle having prime mover and motor-cycle - Google Patents

Abstract

PROBLEM TO BE SOLVED: To safely and smoothly travel a curved road in the night by always allowing a headlight rotatable around a center shaft with slots and rails without fixing the point of contact between the center shaft and a vehicular body and by installing a weight at its lower part. SOLUTION: This headlight 1 is so mounted as to be always rotatable around a center shaft 2 without fixing the point of contact between its center shaft 2 and a vehicular body 3, forming spaces by means of slots 4 and rails 5, and a weight 6 is installed at the lower part of the headlight 1. Thereby, when a bicycle having a prime mover and a motor-cycle tilt the vehicular body 3 intending to turn a curved road while only lighting the headlight to travel in the night, the headlight 1 rotates by means of the center shaft 2, the slots 4 of the vehicular body 3 and the rails 5, and the light-ray is always kept horizontal by the weight 6. Or, it is effective that a bearing is installed at the point of contact between the center shaft 2 of the headlight 1 and the vehicular body 3, and the weight 6 is installed at the back lower part of the center shaft 2 of the headlight 1.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motor-driven bicycle and a headlight of a motorcycle which are rotatable and movable.

[0002]

2. Description of the Related Art Conventionally, headlights of a motorbike and a motorcycle are fixed to a vehicle body, and when turning a curve during traveling, the vehicle turns while tilting the vehicle body. As in the case of FIG. 3, the headlight and the illuminated portion also tilt, as in the case of the tilt of the vehicle body. As a result, the front of the curved road in the traveling direction is dark and the field of view is narrow, which is dangerous.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to develop a headlight capable of driving safely and smoothly on a curved road at night, except for its disadvantages.

[0004]

The means for solving the problem will now be described with reference to the drawings. (A) The contact between the center shaft 2 of the headlight 1 and the vehicle body 3 is not fixed, and the groove 4 is formed around the center shaft 2. A gap is formed by the rails 5 and is mounted so that it can be always rotated. (B) A weight 6 is provided below the headlight 1.

[0005]

According to the present invention having the above-described structure, the motor-operated bicycle and the motorcycle can still turn on the headlights at night and run just by turning the vehicle body to turn on a curved road. When the headlight 1 is tilted, the headlight 1 is rotatably movable by the center shaft 2, the groove 4 of the vehicle body 3, and the rail 5, and the light 6 is always kept horizontal by the weight 6 as shown in FIG. 4.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In carrying out the present invention, the following can be performed. (B) At the contact point between the center shaft 2 of the headlight 1 and the vehicle body 3,
Install the bearing 9. (B) The same effect can be obtained by attaching the weight 6 to the lower rear portion of the center shaft 2 of the headlight 1.

[0007]

Therefore, when traveling on a curved road with a motorbike and a motorcycle at night, the headlights illuminate the front further, so that the vehicle can travel safely and smoothly.
