Abstract

PURPOSE:To permit to start the engine easily by a method wherein a kill switch is switched to the condition of engine-run through a flexible cooperating member when a starter switch is operated under a condition that the engine is being stopped by the seesaw type kill switch. CONSTITUTION:The push-type strater switch 4 is provided with the flexible cooperating member 6 movable to the lengthwise direction thereof by the advance or retreat of a knob 42. When the starter switch 4 is operated under the condition that the engine is being stopped by the operation of the seesaw type kill siwtch 51, a kill switch knob 52 is pushed up and the kill switch is switched into the condition of engine-run. Accordingly, the kill switch knob 52 returns automatically upon re-starting the engine even in case the kill switch 52 is not returned to the position of engine-run, therefore, the starting operation of the engine may be facilitated. On the other hand, the starter switch knob 42 and the kill switch knob 52 are cooperated through the flexible interlocking member 6, therefore, degree of freedom may be obtained in the arrangement, mechanism and design of the run-off switch.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an engine run-off switch device comprising a starter switch and a kill switch disposed near the handlebar grip of a motorcycle.

The starter switch mentioned above is generally a bushing switch with an automatic recovery function, and the kill switch is a self-locking seesaw type or lever set switch. If you forget to turn off the engine and operate the starter switch without returning the kill switch to the engine run position, the engine will not start and may be mistaken for a malfunction.

In order to solve the above problem, as shown in Fig. 4, the knob A of the bush type starter switch and the knob B of the seesaw type kill switch are brought close to each other, and when the kill switch knob B is operated to the engine OFF position, the The stepped portion Bl formed on a part of the knob B protrudes within the movement path of the starter switch knob A, and unless the kill switch knob B is returned to the engine run position, the tip AI of the knob A will be damaged even if you try to operate the starter switch. It is conceivable to make it so that it hits the stepped portion B1 and cannot be pressed.

However, the proposal described in -1- only informs that the kill switch remains in the engine off state due to the inability to push the starter switch knob A, prompting the engine to return to the state IE of engine running, and turns the kill switch on the engine. It is necessary to restore the running condition and operate the starter inch again.

The purpose of the present invention is to provide an engine run-off switch device that can be easily started even if the kill switch is operated in the engine-off state, and is operated by moving the starter switch knob back and forth. The present invention is characterized in that a flexible interlocking member is provided, and when the starter switch is operated, the kill switch knob is pushed down by the flexible interlocking member to switch to the engine run state.

To explain the structure of the embodiment shown in the drawings, 1 is a steering handle pipe, 2 is a handle grip provided at the end of the pipe 1, and 3 is fixed around the handle pipe 1 adjacent to the base of the grip 2. It is a grip holder and switch case.

Assemble the punch type starter switch 4, 41 and scene type kill wiper 5φ51 into the switch case 3,
The operation knobs 42 and 52 of each switch are arranged on the circumferential surface of the case 3 in close proximity to each other.

A flexible interlocking body 6 made of a wire or a thin rod made of soft synthetic resin, integrated with or separate from the starter switch knob 42 , is heated from the back of the knob 42 to the vicinity of the kill switch knob 52 , and the tip thereof is connected to the kill switch knob 52 . It faces the back of the off operation section. The rq for the fixed contact 4 of the starter inch is attached to a part of the flexible interlocking body 6.
A moving contact 41 is attached.

A movable contact 51 for the fixed contact 5 of the kill switch is attached to a part of the off operation part of the kill switch 52.

The starter switch knob 42 is biased to protrude by 4=J by the action of a compression spring 7 provided behind it. The kill switch knob 52 includes a self-locking mechanism (not shown) and is configured to stop at the engine-off position and the run position, respectively.

Figure 3 shows the engine ignition circuit and starting circuit, 8 is the battery, 9 is the main switch, 10 is the relay contact of the starter switch, 11 is the starter motor, 12 is the ignition unit such as a magneto, and 13 is the ignition. The coil 14 is a spark plug.

The gill switch knob 52 protrudes from the case 3 when the engine is rotating as shown by the solid line in Figure 2 and in the state shown in Figure 3.
When pushed in as shown by the chain line, the mouth f moving contact 51 changes to the fixed contact 5.
The ignition circuit is grounded when it comes into contact with the ignition circuit, making it impossible to ignite and stopping the engine. Even if the finger is released from the knob 52, the knob 52 remains in the pushed-in position due to the self-locking mechanism, and the engine remains off.

When the starter switch knob 42 is pushed against the spring 7 in order to restart the engine, the flexible interlocking member 6 is pushed forward and the kill switch knob 52 is pushed up to the position shown by the solid line. That is, at the same time as the kill switch contacts 5 and 51 are heard to return the ignition circuit to the engine running state, the starting switch contact 41 of the starter switch contacts the fixed contact 4 to close the starting circuit.

After the engine starts running, when you release your finger from the starter switch knob 42, the knob 42 returns to its original position and the starter switch contacts 4 and 41 open, but the kill switch knob 52
maintains the engine run position, so the engine continues to rotate.

After increasing the engine by operating kill switches 5 and 51,
By pressing the opposite end 521 of the kill switch knob 52 protruding from the peripheral surface of the switch case 3, the ignition circuit can be restored without operating the starter switch 42.

As described above, the engine run-off switch device for a motorcycle according to the present invention is provided with a flexible interlocking member 6 that is moved in the longitudinal direction by advancing and retracting the 7-buttons 42 of the bushing-type starter switch and wheels 4 and 41. 5.51
When the starter inch 4, 41 is operated when the engine is stopped, the kill switch knob 52 is pushed up via the flexible interlocking member 6, and the kill switch 5, 5 is activated.
1 to the engine run state, when restarting the engine, the kill switch knob 52 is automatically switched to the engine run state in conjunction with the push-in operation of the starter switch knob 42, without having to return the kill switch knob 52 to the engine run position. Since it returns, starting is easy.

Interlocking the starter switch knob 42 and the kill switch knob 52 with the flexible interlocking member 6 has the effect of facilitating design because the arrangement and mechanism of the starter switch and kill switch have L4 characteristics.

Note that even if you accidentally press the starter switch knob 42 at the same time when you press the kill switch knob 52 to stop the engine, the flexible i! 1! Since the movable member 6 is deflected, the kill switches 5 and 51 are properly closed.
