Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an improvement of a key interlock device for an automobile automatic change lever.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 3, in an automobile automatic change lever, when the change lever 1 is outside the parking range P and the engine key 2 is turned to the LOOK (lock) position when the engine is turned off, the cam 3 Tries to push up the slider 4, but the slider 5 at the locked position restricts the upward movement of the slider 4, so that the engine key 2 cannot be removed from the key cylinder 6 by turning it to the LOOK position. The device has been put to practical use (see, for example, Japanese Utility Model Laid-Open No. 2-40154).

When the change lever 1 is in the parking range P, the plate 7 integrated with the change lever 1 pushes out the interlock cable 8 in the direction of arrow A, and the interlock cable 8 causes the slider 5 to move to the unlock position. The engine key 2 can be pulled out from the key cylinder 6 by turning the engine key 2 to the LOOK position so as not to restrict the upward movement of the slider 4 by moving to.

[0004]

[Problems to be solved by the device]

 However, as long as the change lever 1 is shifted to the parking range P, the engine key 2 can be turned to the LOOK position and withdrawn from the key cylinder 6, so that the push button 1a of the change lever 1 at the parking range P is erroneously operated. If the detent pin 1b is disengaged from the detent groove of the detent plate 9 by continuing to press, the change lever 1 can be shifted to other ranges R to 1 even after the engine key 2 is removed. ..

Therefore, an object of the present invention is to provide a key interlock device for an automobile automatic change lever, which prevents erroneous operation in advance and improves safety.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, the present invention provides a key interlock device for an automatic change lever for an automobile, wherein a change lever pushes out an interlock cable in a parking range to turn an engine key to a lock position. A first lever capable of abutting the cable to push out the interlock cable with a spring biasing force, and a second lever capable of locking the first lever at a non-contacting position against the spring biasing force. And the second lever is rotated to the non-locking position by the detent pin of the change lever that moves up in the parking range, and the first lever is the detent of the change lever that shifts from the parking range to another range. The pin is pivoted to the non-contact position.

[0007]

[Action]

 According to the key interlock device of the present invention, when the change lever is other than the parking range, the second lever locks the first lever in the non-locking position and the interlock cable is not pushed out, so that the engine key is locked. It cannot be turned to the position. Next, even if the change lever is shifted to the parking range, if the detent pin is in the lowered position (the push button is not returned), the second lever will not be rotated to the non-locking position. The lever remains locked in the non-contact position and the interlock cable is not pushed out, so the engine key cannot be turned to the locked position.

Then, when the push button is returned, the detent pin rises and the second lever is rotated to the unlocked position, whereby the first lever pushes out the interlock cable with the biasing force of the spring. The engine key can be turned to the locked position and removed. On the other hand, when the push button is pushed in the parking range, the detent pin lowers, and when the change lever is shifted to another range in this state, the first lever is rotated by the detent pin to the non-contact position and the second lever is moved. It will be locked by and you will not be able to push out the interlock cable.

【Example】

 Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. As shown in FIGS. 1 and 2, the change lever 10 can be shifted to the parking range P and the other ranges R to 1. The change lever 10 is provided with a push button 11, and the push operation of the push button 11 lowers the detent pin 12, and the return operation (ampush) raises the detent pin 12. The detent pin 12 engages with the detent grooves 13a, 13b, ... Corresponding to each range P to 1 of the detent plate 13 in the raised position to hold the change lever 10 in the range.

One end of the interlock cable 14 faces the front position of the change lever 10 in the parking range P, and the other end of the interlock cable 14 has a key cylinder as shown in FIG. 6 is connected to the slider 5. When the interlock cable 14 is pushed out in the direction of arrow A, the slider 5 moves to the unlock position and the engine key 2 can be turned to the LOOK position and pulled out from the key cylinder 6.

On the other hand, an L-shaped bracket 16 is provided at a position lateral to the parking range P of the change lever 10, and a first lever 17 is pivotally attached to one side of the bracket 16 by a pin 18. A second lever 19 is pivotally attached to the other side by a pin 20.

The first lever 17 includes a cable contact portion 17 a capable of contacting one end of the interlock cable 14, and a pin contact portion 17 b capable of contact when the detent pin 12 is lowered. , A locking pin 17c is provided, and the cable contact portion 17a is biased in a direction to push out the interlock cable 14 (counterclockwise) by a wire spring 21 wound around the pin 18.

The second lever 19 is provided with a locking portion 19a capable of locking the locking pin 17c of the first lever 17 and a pin abutting portion 19b capable of abutting when the detent pin 12 is raised. The locking portion 19a is urged in the (right-handed) direction to lock the locking pin 17c by the coil spring 22 stretched between the bracket 16 and the bracket 16.

The relationship between the detent pin 12 and the first lever 17 and the second lever 19 will be described in detail. When the push button 11 of the change lever 10 is pressed, the detent pin 12 is lowered and the locus B is reached. When each range P to 1 is moved and the push button 11 is returned by the parking range P, the detent pin 12 moves up along the locus C.

When the locking pin 17 c of the first lever 17 is locked by the locking portion 19 a of the second lever 19 against the biasing force of the wire spring 21, the cable contact portion of the first lever 17 is 17a is the non-contact position of the interlock cable 14, and the pin contact part 17b is in the non-contact position below the locus B of the lowered detent pin 12. Further, the pin contact portion 19b of the second lever 19 is in the non-contact position above the locus B of the lowered detent pin 12.

When the detent pin 12 rises along the locus C, the detent pin 12 abuts on the pin abutting portion 19 b of the second lever 19, and the second lever 19 resists the biasing force of the coil spring 22. It is rotated to a non-locking position shown by a chain double-dashed line in FIG. As a result, the locking of the locking pin 17c by the locking portion 19a is released, and the first lever 17 is rotated by the urging force of the wire spring 21 to the contact position shown by the chain double-dashed line in FIG. The contact portion 17b comes into contact with the locus B.

According to the above configuration, the change lever 10 is now in a range R to 1 other than the parking range P, and the push button 11 is pushed to operate the change lever 10 with the detent pin 12 lowered. When the shift operation is performed to the parking range P, the detent pin 12 moves along the locus B between the pin contact portion 17b of the first lever 17 and the pin contact portion 19b of the second lever 19.

In this state, that is, in a state in which the change lever 10 is shifted to the parking range P and the push button 11 is continuously pressed, the first lever 17 is moved to the non-contact position by the second lever 19. Therefore, the interlock cable 14 is not pushed out in the arrow A direction. Therefore, the engine key 2 cannot be turned to the LOOK position.

When the push button 11 is returned, the detent pin 12 rises along the locus C and contacts the pin contact portion 19b of the second lever 19 so that the second lever 19 biases the coil spring 22. It is rotated to the non-locking position (see the chain double-dashed line) against. As a result, the engagement of the engagement pin 17c by the engagement portion 19a of the second lever 19 is released, and the first lever 17 is rotated by the urging force of the wire spring 21 to the contact position (see the chain double-dashed line). Then, the cable contact portion 17a pushes out the interlock cable 14 in the arrow A direction. Therefore, the engine key 2 can be pulled out by turning it to the LOOK position.

On the other hand, when the change lever 10 is shifted from the parking range P to another range R to 1, when the push button 11 is pressed, the detent pin 12 is lowered, and the second lever 19 follows the coil spring. It is rotated to the locking position by the urging force of 21. When the change lever 10 is shifted to another range R to 1 in this state, the detent pin 12 moves along the locus B and contacts the pin contact portion 17b of the first lever 17, and the first lever 17 moves to the wire. It is rotated in the non-contact direction against the biasing force of the spring 21. As a result, the locking pin 17c of the first lever 17 is locked again in the non-contact position by the locking portion 19a of the second lever 19.

[0021]

[Effect of the device]

 As is apparent from the above description, the key interlock device of the present invention is provided with the first lever capable of pushing out the interlock cable and the second lever capable of locking the first lever, and the second lever. Is to be rotated to the non-locking position by the detent pin of the change lever that moves up in the parking range. Therefore, even if the change lever is shifted to the parking range, the detent pin does not rise unless the push button is returned, and the first lever does not push out the interlock cable, so the engine key cannot be turned to the lock position. This improves safety by preventing the malfunction of operating the change lever to another range after removing the engine key by mistake.
