Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a dynamo on/off device for a bicycle that can be operated while riding.

[Conventional technology]

The dynamo attached to the bicycle was such that the control lever of the dynamo was turned down to turn it on, and raised to turn it off. In order to tilt and raise the control levers, the user must either get off the bicycle or do so while riding the bicycle in an unreasonable position with one leg stretched out.

[The problem that the idea aims to solve]

The purpose of this invention is to provide a novel dynamo on/off device for a bicycle that allows the user to easily and safely turn on/off the dynamo at the handlebars while riding the bicycle. That is.

[Means to solve the problem]

In order to achieve the above object, the dynamo on/off device in the bicycle of the present invention includes a pipe 3 of an appropriate length, a push-down body 5 connected to the upper end of the pipe 3, and a movable member inside the pipe 3 that can freely move up and down. The operating rod 6 is inserted and its upper end is fixed to the pusher 5
and a spring 7 that returns the push-down body 5 and the operating rod 6 upward.
and a hollow chamber part 9 connected to the lower end of the pipe 3,
A rotating shaft 10 that is rotatably supported within the hollow chamber 6 and has one end extending outside the hollow chamber 6, and a rotating shaft 1.
A sliding rod 12 whose intermediate point is unrotatably fixed at a location in the hollow chamber 9 at 0, and a sliding rod 12 arranged between both left and right sides of the lower end of the operating rod 6 and both left and right ends of the sliding rod 12. A pair of left and right links 14 whose lower ends are supported on both left and right ends of the sliding rod 12 and whose upper ends are slidably pressed against both left and right sides of the lower end of the operating rod 6 by a spring 16;
14', a switching member 18 in the shape of a fountain pen whose center part is rotatably supported at a location near the lower end of the operating punch 6, and engaging claws provided on both left and right sides of the upper part of the switching member 18. 17, 17',
When the push-down body 5 is pressed down against the acting force of the coil spring 7, the right engaging claw portion 17' engages with the upper end of the right link 14', and in this engaged state, the right link 1
4' to rotate the sliding rod 12, rotating shaft 10, and driving side crank 13 by a predetermined angle in the positive direction, and with this rotation, the left link 14 is pushed up and the lower left inclined edge 20 of the switching member 18 is pushed up. When the pressing force on the push-down body 5 is released, the operating rod 6 and the switching member 18 return upward due to the action of the spring 7, and during this return, they slide upward from the upper end of the right link 14'. When the switching member 18 is positioned, the upper end of the left link 14 slips under the left engaging claw part 17 due to the action force of the tension spring 16, and the next time the push-down body 5 is pressed down, the left engaging claw part 17 closes to the left link. 14, and in this engaged state, push down the left link 14 to release the sliding rod 1.
2. Rotate the rotating shaft 10 and the driving side crank 13 by a predetermined angle in the opposite direction, and with this rotation, the right link 14' is pushed up and slides up the lower right inclined edge 20' of the switching member 18, and is pushed down again. When the pressing force on the body 5 is released, the actuating rod 6 and the switching member 18 return upward due to the acting force of the spring 7, and in the middle of this return, the switching member 18 is positioned above the upper end of the left link 14. The upper end of the right link 14' is adapted to slip below the right engaging claw portion 17' by the action of the tension spring 16.

At the same time, a coil spring 7 is attached around the upper end portion of the operating rod 6.
The upper end of the coil spring 7 is pressed against the top wall of the push-down body 5, and the lower end is pressed against the upper end of the pipe 3, respectively, and a flat and vast hollow chamber 9 is integrally extended to the lower end of the pipe 3. , a rotating shaft 1 is installed in this hollow chamber 9.
0 is rotatably supported, and a sliding rod 12 is inserted into the hollow chamber 9, and the intermediate point of the sliding rod 12 is unrotatably fixed to the rotating shaft 10. protrudes out of the hollow chamber 9, and the crank 13 is attached to the protruding end, and a pair of left and right links 14, 14' are provided between the left and right sides of the lower end of the operating rod and between the left and right ends of the sliding rod 12. The lower end of the left link 14 is connected to the left end of the sliding rod 12, the lower end of the right link 14' is connected to the right end of the sliding rod 12 by pins 15, 15', respectively, and the lower ends of the left and right links 14, 14' are connected. Both ends of the tension spring 16 are connected to the nearing point, and the upper ends of the left and right links 14, 14' are slidably pressed against both left and right sides of the lower end of the operating rod 6, and A switching member 18 is disposed in the shape of a fountain pen and has engaging claws 17, 17' on both left and right sides of the upper part, and its central part is rotatably fixed to the operating rod 6 by a support shaft 19. However, when the push-down body 5 is pressed down against the acting force of the coil spring 7, the right engaging claw portion 17' engages with the upper end of the right link 14', and in this engaged state, the right link 14'
Press down to rotate the sliding rod 12, rotating shaft 10 and crank 13 approximately 90 degrees clockwise in FIG.
With this rotation, the left link 14 is pushed up and slides up the lower left inclined edge 20 of the switching member 18, and when the pressing force on the push-down body 5 is released, the action of the coil spring 7 causes the operating rod 6 and the switching member 18 returns upward, and during this return, when the switching member 18 is positioned above the upper end of the right link 14', the upper end of the left link 14 sneaks below the left engaging claw part 17 due to the action force of the tension spring 16. However, when the push-down body 5 is pressed next time, the left engaging claw portion 17 engages with the upper end of the left link 14, and in this engaged state, the left link 14 is pushed down and the sliding rod 1 is pressed down.
2. The rotating shaft 10 and the driving side crank 13 are connected to the first
In the figure, it rotates approximately 90 degrees counterclockwise, and with this rotation, the right link 14' is pushed up and slides up the lower right sloped edge 20' of the switching member 18, and also exerts the above-mentioned pressing force on the pressing body 5. When released, the actuating rod 6 and the switching member 18 return upward due to the acting force of the coil spring 7, and in the middle of this return, when the switching member 18 is positioned above the upper end of the left link 14, the upper end of the right link 14' The action force of the tension spring 6 causes it to sneak under the right engaging claw portion 17'.

The present invention may be implemented by means of integrating the rotating shaft 10 and the central axis of the operating lever 2' of the dynamo 2 using a coupling or the like.

[Effect]

As shown in FIGS. 1 and 2, the pipe 3 is attached to the bicycle 1 using the attachment part 4 to the bicycle 1, and the operating lever 2' and crank 13 of the dynamo 2 attached to the bicycle 1 are attached. It is used after being mechanically integrated through connection.
