DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention provides a lens that holds a reflecting mirror holding a light bulb in a socket, a lamp case that holds this lens in the opening, and a lamp case that is movable. The present invention relates to a bicycle power generation lamp that includes a generator body to be held.

Construction of the conventional example and its problems A conventional bicycle power generation lamp of this type was constructed as shown in FIG. That is, this first
In the figure, reference numeral 1 denotes a reflecting mirror that holds a light bulb 3 through a socket 2 in the center thereof, and this reflecting mirror 1 is held by a lens 4 made of a synthetic resin having translucent properties. Reference numeral 5 denotes a lamp case that holds the lens 4 by removably fitting it into the front opening, and this lamp case 5 has a spherical part 5a at the rear. Reference numeral 6 denotes a generator body that movably holds the lamp case 5, and this generator body 6 has a protruding shaft 7 that also serves as an output terminal. The shaft 7 of the generator main body 6 first passes through the spherical member 8, then passes through the hole 5b provided in the spherical part 5a of the lamp case 5, and further, inside the lamp case 5, one end 9a passes through the bulb 3. The lead 9 passes through a hole 9c provided in the other end 9b of the lead 9 and is tightened with a nut 11 via a washer 10 made of a conductive spherical plate. In this case, the diameter of the hole 9c provided in the lead 9 is approximately the same as the diameter of the shaft 7, and the diameter of the hole 5b provided in the spherical portion 5a of the lamp case 5 is larger than the diameter of the shaft 7. Therefore, the lamp case 5 can change the irradiation angle with respect to the generator main body 6. However, in the conventional configuration shown in FIG. 1, the other end 9b of the lead 9 is integrated with the shaft 7, but is not held in the lamp case 5, so that the irradiation angle of the lamp case 5 is limited. When the lamp case 5 is moved in order to change the lamp, the light bulb 3 held on the reflector 1 also moves following the movement of the lamp case 5, so that the light bulb 3 and one end 9 of the lead 9
The point of contact with a will move, and as a result,
There was a problem that the contact between the two became unstable.

FIG. 2 shows another conventional example, and only the points different from the conventional example shown in FIG. 1 will be explained. In FIG. 2, the shaft 7 protruding from the generator body 6 first passes through the spherical member 8, then through the hole 5b provided in the spherical portion of the lamp case 5, and then passes through the spherical member 8, as in FIG. Inside the lamp case 5, one end 9a passes through a hole 9c provided in the other end 9b of the lead 9 that comes into elastic contact with the light bulb 3, and is tightened with a nut 11 via a washer 10, which is a conductive spherical plate. . In this case, the other end 9b of the lead 9
is held by a plurality of ribs 5c provided in the lamp case 5, and the diameter of the hole 9c of the lead 9 is larger than the diameter of the shaft 7, similar to the hole 5b provided in the spherical portion of the lamp case 5. Therefore, as in the conventional example shown in FIG. 1, the lamp case 5 can change the irradiation angle with respect to the generator body. In the conventional example shown in FIG. 2, when the lamp case 5 is moved in order to change the irradiation angle of the lamp case 5, the light bulb 3 held on the reflector 1 changes as the lamp case 5 moves. Since the lead 9 also moves together, the contact between the light bulb 3 and one end 9a of the lead 9 will not become unstable. However, in this configuration, the other end 9b of the lead 9
Since the lead 9 is held by a plurality of ribs 5c provided on the lamp case 5, the other end 9b of the lead 9 is attached to the lead 9 when adjusting the irradiation angle of the lamp case 5.
The size must be larger than the movement range of the washer 10 that moves relative to the hole 9c, and on the other hand, the one end 9a of the lead 9 that comes into contact with the light bulb 3 must be wide enough to come into contact with the light bulb 3. Therefore, the lead 9 in the conventional example shown in FIG. 2 has an unusual shape, and as a result, it is unreasonable in terms of material removal.

Purpose of the Invention The present invention has been made to solve the above-mentioned conventional problems, and provides a power generation lamp for a bicycle in which the material of the lead can be easily removed and the contact between the lead and the light bulb does not become unstable. The purpose is to

Structure of the Invention In order to achieve the above object, the present invention protrudes from a generator main body with a shaft that also serves as an output terminal, and protrudes into the lamp case from a hole provided in a spherical part of the lamp case. Inside the bulb, one end of the lead comes into elastic contact with the bulb, and the other end of the lead is
In a bicycle power generating lamp which is movably held between the spherical part of the lamp case and a washer made of a conductive spherical plate, the lead is shaped like a U-shape at one end, the center and the other end. The central part of the lead is held in the lamp case.

With the above configuration, the lead and the lamp case are integrated, and therefore, when the lamp case is moved to change the irradiation angle of the lamp case, as the lamp case moves, the lead and the lamp case become one body. Since the bulb and lead move together, there is no longer any unstable contact between the bulb and one end of the lead, and since the center of the lead is held in the lamp case, the other end of the lead is When adjusting the irradiation angle of the lamp case, there is no longer any restriction on the movement range of the washer made of a conductive spherical plate that moves relative to the other end of the lead. As long as the size is such that it does not come off the washer, electrical continuity between the two can be obtained, so the other end of the lead can have a simple shape, and material can be removed effectively.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 3 to 5. In FIGS. 3 to 5, parts that are the same as those shown in FIGS. 1 and 2 in the conventional example are given the same numbers, and only the points that are different from the conventional example will be described. That is, in FIGS. 3 to 5, the lead 9 has one end 9a, a central part 9d, and the other end 9, as shown in FIG.
The lead 9 is formed into a substantially U-shape, and the central portion 9d of the lead 9 is inserted into a groove 5d provided in the lamp case 5 and held. 1 and 2, as shown in FIG.
A notch 9c' is provided in place of the hole 9c shown in the conventional example shown in the figure. The lamp case 5 is attached to the generator main body 6 by the following means. That is, the shaft 7 protruding from the generator main body 6
The other end of the lead 9 first passes through the spherical member 8, then passes through the hole 5b provided in the spherical part 5a of the lamp case 5, and then inside the lamp case 5, the other end of the lead 9 has one end 9a in elastic contact with the light bulb 3. A washer 1 made of a conductive spherical plate passes through a notch 9c' provided in the portion 9b.
0 and is tightened by a nut 11.
At this time, the washer 10 contacts the other spherical end 9b of the lead 9 and maintains contact with the shaft 7.

Further, as shown in FIG. 5, the lead 9 has the bent portions 9e and 9f narrower in width than the central portion 9d, so that the lead 9 can be easily bent into a substantially U-shape. That is, one end 9a of the lead 9 that comes into elastic contact with the light bulb 3 is connected to the lamp case 5.
is bent after being attached to the generator main body 6, but in this case, since the width of the bending portion 9f is narrow, it can be easily bent.

The operation in the above configuration will be explained. In order to change the irradiation angle of the lamp case 5,
When the lamp case 5 moves, the light bulb 3 held on the reflector 1 and the lamp case 5 move.
Since the leads 9 held in the bulb move together, the bulb 3
The contact point between the lead 9 and the one end 9a of the lead 9 does not move. At this time, the other end 9b of the lead 9 is connected to the spherical member 8 together with the spherical part 5a of the lamp case 5.
Since the lead 9 and the shaft 7, which also serves as the output terminal, will slide while being sandwiched between the lead 9 and the washer 10.
Electrical continuity can be obtained through the washer 10. In this case, the other end 9b of the lead 9 is connected to the washer 1.
Since conduction can be obtained simply by positioning it at a location that does not deviate from 0, it does not require a wide range of materials. In addition, 12 is the washer 10 and the nut 1.
This spring washer 12 is provided to prevent the nut 11 from loosening and to apply an urging force to the lamp case 5.

Effects of the Invention As described above, according to the present invention, the lead is formed into a substantially U-shape at one end, the center, and the other end, and the center of the lead is held in the lamp case. The lead and lamp case are integrated, so if you move the lamp case to change the illumination angle of the lamp case, the bulb held by the reflector and the lead will move together as the lamp case moves. Therefore, the contact between the bulb and one end of the lead is no longer unstable, and since the center of the lead is held in the lamp case, the other end of the lead can adjust the irradiation angle of the lamp case. There is no longer any restriction on the movement range of the washer, which is a conductive spherical plate that moves relative to the other end of the lead during adjustment, and as a result, the size of the other end of the lead does not deviate from the washer. If the size is large enough, conduction between the two can be obtained, so the other end of the lead can have a simple shape, and material can be effectively removed.
