Description

[Detailed description of the invention] [Industrial application field] The invention relates to a safety device for a motorcycle such as a bicycle.

[Conventional technical field]

For example, a pair of left and right hand brakes are mounted on the handle of a bicycle, the left one for the rear wheels, and the right one for the front wheels.

[Problems to be solved by the invention]

As described above, if the right and left sides are single-purpose, the rear wheel may be braked first due to an operation error, which may be dangerous.

The present invention has been made to solve such a problem, and an object thereof is to improve safety.

[Means for solving the problem]

In order to achieve the above object, the present invention relates to a two-wheeled vehicle such as a bicycle provided with a brake operating mechanism for operating both a front wheel and a rear wheel by operating a single brake lever. A switch for operating a turn signal is provided in addition to the above, and an electric switch is provided between the turn indicator disposed on the rear wheel side and the switch while being wound around the wire around the wire via a wire of a brake operating mechanism. It is characterized by being connected by wiring.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment.

FIG. 1 shows an embodiment of the present invention. In this embodiment, a bicycle is used as an example, and a brake operating mechanism 20 that can brake both the front wheel and the rear wheel with a single brake lever 7 is attached to a grip 30 of an umbrella 36 used for riding a bicycle. First, the brake operation mechanism
It starts from 20.

That is, as shown in detail in FIG. 2, the operating mechanism 20 includes the lever mounting body 2 attached to the grip 30 by the stopper 3, and the mounting of the mounting body 2 is performed by tightening the fastener 4. Made by The lever mounting body 2
Are connected to two outer wires 5,5, and inner wires 6,6 from the outer wires 5,5 are connected to a lever 7, respectively. The lever 7 is rotatable around a rotation shaft 8, and tops 9, 9 are provided at two places. The inner wires 6, 6 pass through the tops 9, 9, respectively, and are guided rearward. A spring 10 and a nut 11 are attached to the inner wires 6, 6, respectively. As a result, the two inner wires 6, 6 are arranged such that one is away from the rotating shaft 8 and the other is near the rotating shaft 8. The distant inner wire 6 is for the rear wheel, and the nearby inner wire 6 is for the front wheel. When the lever 7 is operated, the distant inner wire 6 is pulled more and the nearby inner wire 6 is pulled less. . Therefore, the operation of the lever 7 does not brake the front wheels first, but first brakes the rear wheels, and then brakes the front wheels.

A bicycle provided with such a one-lever front-wheel / rear-wheel differential brake operation mechanism for safety, and further provided with a battery in the grip 30 and an external switch 31 for operating a turn signal. It has become. When the switch 31 is pressed, the direction indicator 33 provided on the rear wheel fender 32 is energized to indicate the direction. Two switches 31 are required. 34 is the electrical wiring for that,
While being wound around the wires 5 and 6 along the wires 5 and 6, it is guided to the direction indicator 35 on the rear wheel fender 32 side. Note that the direction indicator 35 may be provided on the outer peripheral edge of the umbrella 36.

3 and 4 show additional examples for the brake mechanism as well. In the embodiment shown in FIG. 3, the brake mechanism 20 mounted on the handle is detachably mounted so that it can be temporarily mounted on the grip 22 of the umbrella 21 when riding a bicycle. Since the brake operation mechanism 20 is the same as described above, the same reference numeral is assigned. In this case, besides bringing the wires 6, 6 as they are,
The original wire may be detached from the lever attachment 2 so that a new wire can be attached to the lever attachment 2. The mechanism 20 can be attached and detached by one-touch operation.

FIG. 4 shows a configuration in which the brake operating mechanism 20 is mounted on a grip 43 of an umbrella 42 mounted by using a stand 41 erected on a handle 40.

[Effect of the invention]

As described above, according to the present invention, a safety pursuit type two-wheeled vehicle equipped with a mechanism capable of operating both a front wheel and a rear wheel by operating a single lever is provided. In addition to the indicator, a switch for operating the same direction indicator is provided, and its electric wiring is guided while being wound around the outer periphery of the wire through the wire of the brake mechanism. It is useful as it can greatly enhance the running.

In particular, since wiring can be performed simply by winding, assembly work can be performed very easily, and it is difficult to apply operating resistance to the wire and smooth movement of the wire compared to the case where the wire is guided with a fastener around the wire. Can be guaranteed. Even if the wiring is broken in the middle, the wiring is guided while being wound around the wire, so that there is a dimensional margin due to the winding, so that repair can be performed more easily and reliably than when the wiring is led straight.
