Description

[Detailed Description of the Invention] This invention relates to an improvement of a direction indicating switch with a lane change mechanism.

Conventionally, when turning left or right while driving a car, it is necessary to switch the direction switch to the direction change position and lock it for a relatively long period of time. All you have to do is flip a switch. From this point of view, direction indicator switches have been put into practical use that are equipped with a lane change mechanism that switches the direction indicator switch only while the operating lever is being operated, before the operating lever switches the direction indicator switch to the direction change position and locks it. .

However, in the conventional direction indicating switch with a lane change mechanism, the lane change mechanism is provided on the sliding path of the switch switching actuation member that slides in conjunction with the operation of the operation lever. There is a high risk that the direction indicator switch will be switched to the direction change position and locked due to an operational error.
It was troublesome and required skill to operate.

This invention was made in order to eliminate the above-mentioned drawbacks of the conventional technology.It is possible to instantly recognize the lane change operation and the direction change operation of the direction indicator switch, and is a lane change engine that has a simple structure and operates reliably. This provides a new mechanical direction indicator switch.

Hereinafter, one embodiment of this invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the direction indicating switch with lane change mechanism is mounted on the support shaft 1.
The case body 3 is attached to the case body 3 via a metal fitting 2, and the case body 3 is provided with a sliding groove 4 in a direction perpendicular to the support shaft 1.

Between the sliding groove 4 and the support shaft 1,
A switch storage groove 6 is further provided through the partition wall 5, and within the storage groove 6, a left direction indication changeover switch 7 and a right direction indication changeover switch 8 are provided. Power contact 7
Push rods 9 and 10, which are slidably fitted into the partition wall 5, are linked to the slide grooves 4a and 8a.
The changeover switches 7 and 8 can be turned on and off by pushing the push rods 9 and 10 facing inside.

A box-shaped hollow bracket 11 is fitted into the sliding groove 4 and is slidably guided in the switch switching direction by the sliding groove 4. hole 11b,
A switch switching actuation member 12 integrated with an operating lever 12a extending outward from a long groove 3a of a case body 3 is housed with a certain clearance C in the thickness direction.

A push rod 9 of the partition wall 5 is provided on the surface 12b of the actuating member 12 facing the partition wall 5.
A spring (specifically shown in FIG. (not shown) is fitted into the ball hole 12d.

Further, on both sides of the actuating member 12, there are inclined cams 11 formed on both inner sides of the hollow bracket 11.
Return balls 15a, 15a contacting a, 11a
are applied to the ball holes 12c, 1 via a spring (not specifically shown) that urges the cams toward the inclined cams 11a, 11a.
2c. The return ball 15a, 1
5a is the inclined cam 11a of the hollow bracket 11,
11a to cause the hollow bracket 11 to move together with the actuating member 12 in the switch switching direction, and the actuating member 12 always abuts the partition wall portion 5 to apply a biasing force to push down each push rod 9, 10. When the actuating member 12 is tilted within the hollow bracket 11 within the range of the clearance C, the actuating member 12 is brought back into contact with the partition wall 5 by the action of the inclined cams 11a, 11a.

Further, the opposing surface 12b of the actuating member 12 has a lock that engages with the lock hole 5a of the partition wall 5 to lock the actuating member 12 in the left position L when the actuating member 12 slides in the left switch switching direction. Spring 16a
A switch cam 17a is provided to release the push rod 9 of the left direction changeover switch 7, and when the operating member 12 slides in the right switch direction, it engages with the lock hole 5b of the partition wall 5. A lock spring 16b for locking the operating member 12 in the right position R and a switch cam 17b for releasing the push rod 10 of the right direction changeover switch 8 are provided.

In order to perform a lane change operation using the direction indicating switch with a lane change mechanism configured as described above, for example, as shown in FIG.
When 2a is operated in the right position R direction, the actuating member 12
is tilted within the bracket 11 within the range of clearance C. Then, the opposing surface 1 of the actuating member 12
2b separates from the partition wall 5, and the push rod 10
is released and the right direction instruction changeover switch 8 is released.
is turned on.

Then, after changing lanes, the operating lever 12a
When the hand is released, the actuating member 12 is returned to contact with the partition wall 5 by the action of the inclined cams 16a, 16a by the return balls 15a, 15a, and the push rod 10 is pushed down again to turn off the right direction changeover switch 8. I come to do it.

Next, in order to perform a direction change operation, as shown in FIG.
The push rod 10 is released from being depressed and the right direction changeover switch 8 is turned on.

Then, when the operation lever 12a is further operated in the direction of the right position R while the actuation member 12 is tilted, the actuation member 12 slides together with the hollow bracket 11 in the direction of the right position R, and the lock spring 16b locks into the lock hole. 5b, the actuating member 12 is locked in the right position R.

If you release your hand from the operating lever 12a in this state,
Inclined cam 16 by return balls 15a, 15a
The actuating member 12 returns to abut against the partition wall 5 due to the action of the push rods 10 and 16a.
is fitted into the switch cam 17b of the actuating member 12 and is not pressed down, so the right direction instruction changeover switch 8 remains turned on.

After the direction change, the lock of the actuating member 12 is released by an auto-cancel mechanism (not shown) or the like, and when the actuating member 12 slides together with the hollow bracket 11 toward the neutral position N, the bushing rod 1
0 is pressed down again by the actuating member 12 to turn off the right direction instruction changeover switch 8, and the neutral ball 14 fits into the inclined recess 13 and the actuating member 12
returns to the neutral position N (see Figure 1).

Although the above description has been made regarding the case where the operating lever 12a is operated in the direction of the right position R, the same applies to the case where the operating lever 12a is operated in the direction of the left position L.

As is clear from the above explanation, this invention has a sliding groove in the case body inside a freely slidable hollow bracket, and the hollow bracket slides together in the switch switching direction, and also tilts within the hollow bracket. An actuating member for switching the switch is provided, and the actuating member is tilted at the neutral position via the operating lever to change the lane, while the switch is slid while tilted to indicate the direction. Therefore, the operation mode is different from the conventional one, that is, the lane change operation and direction change operation are different, so both movements can be recognized immediately, making it easy and reliable to operate. become able to.

Additionally, the structure is extremely simple, as basically all that is required is a hollow bracket that accommodates the operating member and a mechanism for tilting and self-returning the operating member.
It can be operated reliably.
