Description

The present invention relates to a stop lamp switch device for a vehicle having a bar handle.

[Conventional technology]

For example, in some vehicles traveling on uneven terrain, a brake lever for performing both a traveling brake operation and a parking brake operation is attached to a bar handle.

For example, when parking, the brake is locked with the brake lever pulled, restricting the brake lever from returning to its original position, and applying the parking brake. On the other hand, when the vehicle is running, the lock is released, and when the brake lever is pulled, the brake is applied, and when the brake lever is released, the brake returns to the original position and the brake is released.

[Problems to be solved by the invention]

If the strap lamp is turned on by the brake operation during traveling and the driver of the vehicle traveling behind is informed of the brake operation, the strap is turned on even when the parking brake is operated, causing a problem that the battery is wasted.

Therefore, an object of the present invention is to devise a stop lamp switch device and an electric circuit thereof so that the stop lamp can be reliably prevented from being turned on at the time of operating a parking brake, and its operation is stabilized for a long period of time. Is what you do.

[Means for solving the problem]

The present invention relates to a vehicle such as a motorcycle in which a stop lamp is turned on when a brake lever is operated, and a brake lever that is used for both a brake operation during operation and a parking brake operation is supported by a lever holder attached to a bar handle, and a brake lever is provided. In order to solve the above problems, a stop lamp switch and a parking lock switch are attached to the lever holder, and the operation of the brake lever is performed on the assumption that the vehicle is provided with a lock plate or a lock lever that holds the lock plate in the parking brake operating position. When an electric circuit of a stop lamp which is closed by a stop lamp switch which is opened / closed at a time is provided, and when the brake lever is held at a parking brake operating position,
In this case, the parking lock switch is opened by a lock plate or a lock lever to open the electric circuit.

[Action]

In a normal running state, the lock plate or the lock lever is in the non-operation position, so that the parking lock switch that is opened and closed by this is kept closed. When the brake is applied during operation and the brake is operated, the stop lamp is closed by the brake lever, and the stop lamp electric circuit is closed, so that the stop lamp is turned on to indicate that the vehicle is in the braking state.

When the lock plate or the lock lever is moved to the operation position in a state where the brake is operated by pulling the brake lever, the brake lever is locked in the operation position, and a parking brake state is established. At this time, since the parking lock switch is opened by the lock plate or the lock lever, the electric circuit of the stop lamp is opened again and the stop lamp is turned off.

Therefore, in the parking brake state, it is reliably avoided that the stop lamp (so-called brake lamp) is left lit.

Further, a stop lamp switch and a parking lock switch are attached to the lever holder, and these switches are separately opened and closed by a brake lever, a lock plate, or a lock lever.
The opening and closing stroke of the contacts of both switches can be kept to the minimum necessary, and the electric wire connected to both switches is not moved by the operation of the lever during the brake operation, so that excessive force is applied to the electric wires. There is no danger of disconnection. Therefore, the two switches and the electric wire have excellent durability, and the stop lamp switch device operates stably for a long period of time.

〔The invention's effect〕

The present invention relates to a vehicle such as a motorcycle in which a stop lamp is turned on when a brake lever is operated, wherein a brake lever used for both a brake operation during operation and a parking brake operation is supported by a lever holder attached to a bar handle, and the brake lever For a vehicle provided with a lock plate or a lock lever that holds a parking brake operating position on the lever holder, an electric circuit of a stop lamp closed by a stop lamp switch that is opened and closed by operation of the brake lever is provided, and the brake lever is provided When the parking brake is operated, the parking lock switch is opened by the lock plate or the lock lever to open the electric circuit. By Ngureba is operated, because automatically disappear, with a simple structure, it is possible to reliably prevent would batteries up by unnecessary power consumption.

Further, a stop lamp switch and a parking lock switch are attached to the lever holder, and these switches are separately opened and closed by a brake lever, a lock plate, or a lock lever.
The opening and closing stroke of the contacts of both switches can be kept to the minimum necessary, and the electric wire connected to both switches is not moved by the operation of the lever during the brake operation, so that excessive force is applied to the electric wires. There is no danger of disconnection. Therefore, the two switches and the electric wire have excellent durability, and the stop lamp switch device operates stably for a long period of time.

Further, the brake lever is also used as a parking brake lever, wherein the brake lever is locked at a brake operating position by a parking lever (a kind of lock lever), and the normally open brake switch is closed by the operation of the brake lever. It is known to open the switch again by a locking operation of a parking lever with respect to a brake lever.
No. 1156). However, the positional relationship between the brake lever 4 (see FIGS. 1 and 2 of the publication and the same applies in this section) and the parking lever 7 in the non-operating state of the brake (the state of FIG. 1 of the publication) is as follows. Operator of switch 12
13 is in a state in which the stroke is depressed by a minimum stroke necessary to turn off the switch, and in a state in which the parking brake is operated (the state shown in FIG. The parking lever 7 largely falls down toward the brake lever 4 so as to engage with the notch 11 of FIG. 4 and lock the brake lever (only by the stroke for the engagement pin 9 to engage with the notch 11). Therefore, the operator 13 of the switch 12 turns off the switch.
It is inevitably mechanically required to be pushed far beyond the stroke (stroke A in FIG. 3) necessary for the operation. For this, switch 12
The stroke of the operator 13 is much larger than the stroke required to open the switch 12, so that the stroke of the switch contacts cannot be significantly increased, and the switch contacts are immediately damaged. Will be. For this reason, in the above-mentioned known ones, a switch of a stop lamp (so-called brake lamp) of a vehicle such as a motorcycle is frequently opened and closed.
The durability of the switch is extremely small. In addition, the malfunction of the switch of the stop lamp immediately impedes the safe operation of the vehicle, so that this known device is not practical.

On the other hand, according to the present invention, since the electric circuit of the stop lamp can be opened separately by the stop lamp switch and the parking lock switch, the stroke of the contact point of each switch reliably opens and closes the switch. To the limits needed to
Therefore, there is no durability problem as described above, and the stop lamp can be operated safely and reliably for a long period of time. This is a great advantage of the present invention over the above known ones.

Further, in the above-mentioned known device, the switch 12 is attached to the parking lever 7, so that the switch
12 works, therefore, the wire connected to the switch 12 must be slackened, and since the wire moves, there is a danger that an excessive force will be applied and the wire will be broken. Since the switches S1 and S2 are mounted on the lever holder 2, the electric wires are not moved, and there is no possibility of disconnection as described above.
