Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a hand-operated bicycle dynamo switching device, and by switching a control lever attached to a bicycle handle post, for example, a dynamo attached to a front hawk of a bicycle is set to an operating position and a non-operating position. It is characterized in that it can be switched.
[0002]
[Prior art]
Conventional remote control type bicycle dynamo switching devices include a device that swings an operating lever attached to a bicycle handle and moves a rod connected to the dynamo switching lever up and down (for example, Patent Documents). 1).
There is also a bicycle power generator in which an operation lever attached to a bicycle handle and a dynamo switching lever are connected by a release wire to remotely control the dynamo (for example, see Patent Document 2).
In addition, a dynamo is stretched between the operating lever, which is also attached to the bicycle handle and maintains the switching angle, and the upper part of the dynamo case so that the dynamo can be moved directly between the operating position and the non-operating position. There is also a power generation lamp for a bicycle that can be switched to a hand-operated flashing lamp (see, for example, Patent Document 3).
Conventional switching device described above, both has a drawback that because I attach the operating lever to the bicycle handle will tend to interfere with the steering and braking operation.

[Means for Solving the Problems]
Accordingly, the present invention provides a mounting band that is tightened by winding a handle post of a bicycle, an operating lever that is pivotally attached to the mounting band, an upper end connected to the tip of the operating lever, and a lower end that is a Dynamo for bicycle. A dynamo switching device for a bicycle provided with a connecting rod made of metal wire connected to a switching lever provided in the above, wherein the mounting band and the operating lever are each made of resin and provided on the side surface of the mounting band Switching of the operation lever to both end surfaces of the outer end surface of the bearing portion and the inner end surface of the bearing portion provided coaxially with the bearing portion provided on the side surface of the mounting band on the operation lever side so as to contact the bearing portion Provide uneven parts that mesh with each other so that the angle is fixed, and a barrel bolt inserted into the bearing parts from the outer end surface of the bearing part on the operation lever side is provided in the bearing part on the mounting band side. The outer end of the cushion spring that is screwed into the nut and fitted in the spring receiving hole provided in the bearing portion on the operation lever side is received by the head of the body bolt so that the operation lever can be switched. The bicycle dynamo is characterized in that the movement of the operation lever in the state of being biased in the meshing direction by the cushion spring is absorbed by the attachment band and the operation lever due to the change in the meshing position of the uneven portion. A switching device is provided.
[0006]
The switching device of the present invention configured as described above is provided on the end face portions of both the bearing portions of the mounting band side bearing portion wound around the handle post and the operation lever side bearing portion coaxially provided. Since the concave and convex portions that mesh with each other are provided and the switching angle of the operation lever is set to be constant, the switching operation of the operation lever and the angle holding are performed reliably. In addition, a thick bolt is used for the shaft through which both the bearing portions are inserted, and the cylinder is biased in the meshing direction by a cushion spring interposed between the thick bolt and the bearing portion on the operation lever side. Then, the contact between the mounting band and the operating lever due to the change in the meshing position of the concavo-convex portion is absorbed by the movement of the operating lever while being elastically pushed in the meshing direction by the cushion spring . Switching operation can be done easily. In addition, the mounting band and the operating lever, which are the main components of the device, are made of resin, so that the cost can be reduced, the mounting to the bicycle can be simplified, and the steering operation or the braking operation can be prevented. .
