Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a connecting structure of a connecting rod in a remote device for raising and lowering a dynamo that is mounted on a vehicle body of a bicycle.

[Problems to be Solved by the Prior Art and Invention] Generally, a bicycle is provided with an illumination lamp for safe night driving, but the power supplied to this illumination lamp uses a tiltable dynamo. I'm going. By the way, the dynamo has a drawback that the mounting position is inevitably lowered due to the relationship with the tire, and therefore, when the dynamo is to be tilted in a running state, the dynamo has to be operated in a greatly bent posture.

In order to solve this problem, as shown in Japanese Utility Model Publication No. 63-16622, there are some cases in which the dynamo is tilted by swinging remote operation of an operating member provided near the handle. A structure in which the ring at the upper end of the rod, the lower end of which is connected to the tilting device, is loosely fitted into the hollow boss provided on the operating member, and the retaining member for the ring is integrally screwed into the hollow boss. I'm running. However, the rod has a different diameter depending on the rod length so as not to bend during the tilting operation. Therefore, if the rod has a large diameter, the retaining member will stick out from the boss portion. As shown in Fig. 6, it is troublesome that the ring portion needs to be processed into a flat shape by a mechanical device such as a press. On the other hand, in the case of a small diameter, as shown in Fig. 6A, the ring portion is different from the retaining member. There is a problem that there is a drawback that a plurality of operating members corresponding to the rod diameter must be prepared in advance in order to avoid play caused by playing back.

[Means for Solving the Problems] The present invention has been made in view of the above circumstances and has an object to provide a connecting structure of a connecting rod in a dynamo tilting remote device that can eliminate these drawbacks. In connecting the operation member provided on the vehicle body so as to be swingable, the ring portion formed at the upper end portion of the connecting rod whose lower end portion is connected to the dynamo tilting device in a retaining manner, The ring portion is made to penetrate through the tip of the fitting projection provided on the operation member, and the retaining member for preventing the penetration of the penetrated ring portion is provided on the support portion provided adjacent to the fitting projection. A base end portion is fixedly supported, and a fitting hole that is fitted through the fitting projection distal end portion is formed at a tip end portion extending from the fixed portion so as to support the fitting of the penetrating ring portion. It is characterized by having been made.

Further, according to the present invention, with this configuration, it is possible to cope with rods having various diameters by only preparing one kind of operating member.

[Embodiment] Next, an embodiment of the present invention will be described with reference to the drawings. In the drawings, reference numeral 1 denotes an operating member for remote-controlling the up and down operation of the dynamo 5, and the operating member 1 includes a support shaft 2
Is provided in a protruding manner, and a fixing member 3 configured by using a band is rotatably attached to the fixing member 3. And the operation member 1
Is fixedly attached to the handlebar post 4 of the bicycle using a fixing member 3 so as to be swingable about the support shaft 2 as a fulcrum.

The operating member 1 has a fitting projection 6 through which a ring portion 7a provided at an upper end portion of a rod 7 having a lower end portion connected to a raising / lowering device 5a of the dynamo 5 penetrates, and the loosely fitted ring portion 7a is prevented from coming off. A protrusion-shaped support portion 9 for fixing and supporting the member 8 is provided. In other words, the fitting protrusion 6 has a large-diameter base end portion 6b to a small-diameter front end portion 6a.
Is protruded, and the ring portion 7a penetrates the tip portion 6a in a loose fit manner.

On the other hand, the retaining member 8 formed of a plate member has a base end portion integrally fixed to the support portion 9 by a screw 9a, but a tip end portion 8b extending from the base end portion is loosely fitted to the tip end portion 6a. A fitting hole 8a for fitting with is formed. Then, connect the rod ring portion 7a to the tip portion 6a.
, The fitting hole 8a is fitted into the tip portion 6a, and the tip portion 8b of the retaining member is applied to the tip portion of the fitting projection 6, and the base end portion is attached to the support portion 9 with a screw 9a. By being fixedly supported by, the rod ring portion 7a fitted to the tip portion 6a is retained and supported while being sandwiched between the fitting projection base end portion 6b and the retaining member tip portion 8b. It will be. And the operation member 1
By swinging the spindle 2 around the fulcrum as a fulcrum.
Is operated by pushing and pulling, and the tilting device 5a based on this pushes and pulls the dynamo 5 as a remote operation. Further, a stopper 8c is provided on the outer peripheral edge of the tip end portion 8b of the retaining member, and the stopper 8c is the operation member 1
When the rocking operation is performed, the rod 7 is abutted at an appropriate operating position so that the rod 7 is not bent and the fulcrum is not crossed due to the excessive manipulation (that is, too much manipulation) of the rod 7. The operation member 1 of FIG.

In the embodiment of the present invention configured as described above, the dynamo 5 can be tilted up and down by swinging the operating member 1 to the corresponding side, whereby the rod 7 is pushed and pulled. Then the dynamo 5 starts to fall. Therefore, the dynamo 5 can be easily tilted up and down, and an unreasonable posture in which the dynamo 5 is bent forward is not forced.

As described above, according to the embodiment of the present invention, the dynamo 5 can be tilted up and down as a remote operation from the vicinity of the handle by using the operation member 1. The retaining member 8 for retaining the upper end ring portion 7a of the rod is not fixed to the fitting protrusion 6 with a screw as in the conventional case, but a support portion 9 provided separately adjacent to the fitting protrusion 6 is provided.
The base end is fixed with a screw to be integrally fixed. As a result, the retaining member 8 is provided with a step 8d corresponding to the retaining member 8 even if the diameter of the rod changes depending on the variation of the rod length. By adjusting the amount of sinking of the stopper member tip 8b into the fitting projection 6 in accordance with the screw stopper of the base end, it is possible to respond quickly.
Therefore, the rod ring portion 7a is not pressed into a flat shape, and the retaining member 8 is not attached in a loose state.

In addition, this structure is advantageous in that the excessive swing of the operating member 1 is restricted by the rod 7 coming into contact with the stopper 8c to prevent unnecessary fulcrum crossing.

[Advantages] In summary, since the present invention is configured as described above, it is not necessary to provide an operating member near the handle to perform remote operation of the dynamo in an unreasonable posture in a state where the dynamo is bent forward. Although it is a consideration, the retainer from the tip of the fitting protrusion provided on the operating member of the upper ring of the rod whose lower end is connected to the tilting device is fixed to the fitting protrusion with a screw as in the past. Instead of using a retaining member,
A support portion is provided adjacent to the fitting protrusion, and the tip end portion extending from the base end portion of the retaining member fixed to the support portion is fitted to the tip end portion of the fitting protrusion and applied to the ring portion. Therefore, even if the rod diameter varies greatly, it can be installed immediately by adjusting the amount of immersion of the tip of the retaining member into the tip of the fitting protrusion. It is extremely easy to install.
