[Industrial applications]

 The present invention relates to a gear-type power generator for a bicycle lamp, and more particularly, to a bicycle lamp generator that can be easily and reliably driven with a minimum required force, and the lamp blinks while driving. The present invention relates to a gear type power generator for a bicycle lamp, which can be easily controlled at hand.

[0002]

[Prior art]

 Currently, from a safety point of view, bicycles certainly need to be fitted with lamps. However, the conventional bicycle lamp generator device and its use have the following drawbacks.

[0003]

[Problems to be solved by the device]

 One is related to a conventional bicycle lamp generator, in which a rotating pulley having a pressing stripe (knurl) fixed to the generator drive shaft is brought into contact with the annular side surface of a bicycle tire. Then, when the tire rotates, the rotating pulley is moved by the frictional force on the side surface of the tire, so that a large resistance is applied to the side surface of the tire, the stepping action of a person riding a bicycle becomes considerably tight, and the wheel is biased to one side. Feeling, not even more appropriate. Also, when the vehicle runs on an uneven road surface, the rotating pulley may intermittently slip on the tire side surface due to vibration, or may be disengaged from the tire side surface, causing the lamp to blink. Another drawback relates to a conventional bicycle lamp generator mounting device, in which when the bicycle is stopped, the spanner (lever) of the device is pushed when the rotating pulley is pressed or pulled away from the tire side. I have to pull it, so I find it inconvenient to use. Therefore, the main purpose of the present invention is to solve the various drawbacks of the above-mentioned conventional bicycle lamp generator, and to use the relatively small sideways (in the traveling direction) thrust force only to ensure that the rotary pulley can be mounted on the side of the tire. It can be moved, and it does not slip due to tire vibration, and even while running, you can easily control the contact situation between the rotating pulley and the tire side surface by pulling the spanner attached near the bicycle handle. The purpose of the present invention is to provide a gear-type power generator for a bicycle ramp that can control whether or not a lamp is turned on even while traveling.

[0006]

[Action]

 According to the configuration of claim 1, since the teeth of the rotating pulley of the generator mesh with the teeth of the tire, the rotating pulley is simple and reliable without requiring a large pressing force (friction force) against the tire side surface. Is driven to rotate. On the other hand, the generator body has its support shaft inserted through the shaft hole of the base, and is biased in a direction away from the tire side surface by a torsion coil spring attached to the support shaft. Also, the moving block of the generator body is connected to one end of the wire rope connected to the spanner at hand. Therefore, by operating the wrench at hand against the biasing force of the above-mentioned torsion coil spring, the generator body is driven to rotate around the support shaft, and the meshing state between the teeth of the rotating pulley and the teeth of the tire can be easily done. Obtainable. On the contrary, if the wrench at hand is operated in the opposite direction from this state, the torsion coil spring will rotate the generator body around the support shaft in the direction away from the tire, and the teeth of the rotating pulley and the teeth of the tire will move again. The engagement of can be easily released. The rotation drive range around the support shaft of the generator body is limited to the guide rod inserted in the substantially central position of the support shaft and the blocking block of the blocking rod inserted into the elongated hole of the guide rod. The teeth of the rotating pulley and the teeth of the tire are properly meshed with each other.

According to the structure described in claim 2, in addition to the function described in claim 1, the inner rod is vertically guided by a guide hole provided for inserting an end portion thereof. Swing to prevent the support shaft from coming off the shaft hole.

【Example】

 Next, the features and effects of the invention will be described in detail with reference to the accompanying drawings. As shown in FIG. 1, at the upper end of the neck of the generator body 10 of the present invention, a rotary pulley 11 having a plurality of teeth 11a is provided on the periphery thereof, and the rotary pulley 11 is a generator drive shaft in the generator 10. (It is not shown. It is a conventional technique that the generator main body 10 uses the rotation of the generator drive shaft to generate an electric current, so the description of its internal structure and the like will be omitted.) ing. Further, teeth 51 that mesh with the teeth 11 a of the plurality of rotary pulleys 11 are provided on the annular side surface of the bicycle tire 50 facing the rotary pulley 11.

On the abdomen of the generator body 10, one support shaft 12 and one pulling block 13 are fastened and fixed at appropriate positions. The supporting shaft 12 is inserted into the two shaft holes 20a, 20a of the base 20 facing each other for positioning, and the torsion coil spring 3 is installed between the two shaft holes 20a, 20a. It is worn. Further, a guide bar 121 is inserted laterally at a substantially central position of the support shaft 12 so as to cross it.

One guide hole 20b is further formed in the base 20 at an appropriate position, and the inner hole 20b serves to insert one end of the guide rod 121 and guides the guide rod 121. The vertical movement of the support shaft 12 is prevented and the support shaft 12 is prevented from slipping out of the shaft hole 20a. The torsion coil spring 3 has one end hooked on one end of the guide rod 121 and the other end hooked on the base 20. Referring to FIG. 2, one elongated hole 121a is opened in the substantially central portion of the guide rod 121. Further, a bolt base 21 is extended to the base 20, and a height-adjustable blocking rod 22 is further tightened. The blocking rod 22 penetrates the elongated hole 121a of the guide rod 121 and further lower end. One blocking block 221 is attached to the part.

The blocking rod 22 can control the swinging angle of the guide rod 121 by adjusting the height by adjusting the screwing amount with respect to the bolt base 21, and the teeth 11 a of the rotary pulley 11 of the generator body 10 can be controlled. Both of the tire side teeth 51 can be engaged with each other at an appropriate angle (as shown in FIG. 4). A further bolt base 23 is extended to the base 20, a nut 241 is adjustably attached, and a rotary head 242 having a pressing stripe (lowlet) is attached to one end, and one through hole is formed in the shaft. A manual bolt 24 having an opening 24a is screwed. The moving block 13 is connected to one end of the wire rope 4, and the other end of the wire rope 4 passes through the through hole 24 of the manual bolt 24 and is a spanner (lever) attached near the bicycle handle. It is connected to the. Although the wrench is not shown, the structure of the wrench is an application of the conventional technique, and therefore its explanation is omitted and only its function will be described later.

In the wire rope 4, a portion interposed between the spanner and the bolt 24 is wrapped in one rope jacket 41. Further, one positioning bolt 6 (see FIG. 3) is inserted into the positioning hole 20c on the base 20 to fix the base 20 at an appropriate position on the bicycle frame. By moving the wrench from the state shown in FIG. 3, the wrench pulls the wire rope 4, and pulls the pulling block 13 fastened on the generator body against the elasticity of the torsion coil spring 3. Then, the generator body 10 is rotated about the support shaft 12 by an angle θ (as shown in FIG. 4). Then, the teeth 11a of the rotary pulley 11 at the upper end of the neck of the generator body 10 are meshed with the teeth 5 on the tire side surface. Therefore, when the tire rotates, the rotary pulley is rotationally driven, and at the same time, the generator drive shaft is driven to generate an electric current in the generator main body 10 to turn on the lamp. When the lighting is not needed, the pulling force applied to the wire rope 4 is released only by pulling the spanner back to its original position, and the supporting shaft 12 receives the elastic force of the torsion coil spring 3 (see FIG. 1) to restore the original force. Since the generator body 10 turns back to the original angle and also returns to the original angle accordingly (as shown in FIG. 3), the rotary pulley 11 does not rotate, so that the power generation stops and the bicycle lamp also Disappear at the same time.

[Effect of device]

 As described in detail above, according to the present invention as set forth in claim 1, since teeth are provided on the tire and the rotary pulley, the rotary pulley of the generator main body is surely driven to rotate by the side surface of the tire to cause slippage of the rotary pulley. Not only does this prevent the tire from rolling, but it also reduces the side resistance to the tire as it rotates, so the rider does not feel tight and the tire leans toward one side. In addition, the present invention can control whether or not the bicycle lamp is turned on by pulling a spanner attached near the steering wheel while traveling, and the operation is extremely convenient. Therefore, the present invention is a utility model. It meets the criteria of novelty because it has the requirement of registration and the present invention is different from the conventional one. Further, according to the present invention as set forth in claim 2, in addition to the effect as set forth in claim 1, the guide shaft provided in the guide rod and the base can prevent the support shaft from coming off from the shaft hole. It has an excellent effect.
