Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a locking device for a vehicle operating device, and more particularly to an improved locking device for a vehicle operating device for locking or unlocking the vehicle operating device in conjunction with an engine start key.

In order to prevent vehicle theft, a mechanism is well known in which the vehicle operating device is unlocked only by the engine start key.
It consists of a structure that allows the steering shaft, shift lever, and other operating levers to be operated by moving the engine start key from the lock position to another operating position.

Conventional locking devices have a lock bar that engages a steering shaft or other vehicle operating device to lock operation of the operating device, and when the starting key is rotated to the locked position or removed from the lock mechanism. When the engine is turned, the lock bar locks the operation of the operating device, and when the start key is turned to another operating position, the lock bar is separated from the operating device by the rotation of the key, and the vehicle operating device is ready for operation. be placed.

In the conventional device described above, in the unlocked state, the lock bar is held in the unlocked position by the locking part that moves with the key, but the lock end of the lock bar is always facing the operating device such as the steering shaft. In this standby state, the lock bar could very easily protrude toward the vehicle operating device due to loss, damage, or other malfunction of the locking portion, and there was a risk that the operating device would be locked when the vehicle was running.

The disadvantage of the conventional device described above is that when the starting key is in an operating position other than the locked position, the lock bar is kept in the unlocked state only by the relatively easily damaged locking member.

The present invention has been made in view of the above-mentioned conventional issues, and its object is to move the lock bar away from the position facing the vehicle operating device when the engine start key is in an operation position other than the lock position, thereby locking the vehicle. It is an object of the present invention to provide a locking device for a vehicle operating device that can prevent unnecessary locking accidents of the operating position that occur during driving and can control the locking action of a lock bar by attaching and detaching an engine start key.

In order to achieve the above object, the present invention allows the lock bar to be released from the vehicle operating device to release the lock, and the lock bar itself can be rotated within the lock bar case as the engine start key is rotated. It is characterized by

The lock bar is rotated from the position facing the vehicle operating device when the key is not in the locked position, and its position is regulated by the inner surface of the lock bar case, so there is no risk of damage or other accidents to the cylinder locking device or the mechanism that rotates the lock bar. Even if this happens, the lock bar is in a retracted position where it does not face the vehicle operating device, so it is possible to reliably prevent an accident caused by an unnecessary locking action while the vehicle is running. Further, the present invention includes a holding lever that engages and disengages from the lock bar in response to attachment and detachment of the engine start key, and even when the key is returned to the locked position and the lock bar is rotated back to the position facing the vehicle operating device. , the locking action of the lock bar is reserved by a holding lever.

When the key is inserted, the locking end of the retaining lever engages with the lock bar, and only when the key is pulled out, the key detection unit detects the withdrawal of the key and releases the retaining lever from the lock bar. The locking action of the locking bar is achieved only at this point. According to the present invention, the lock bar can engage with the vehicle operating device only when the engine start key is rotated to the lock position, and only in this state can the locking action be obtained.

Further, according to the present invention, the lock bar is held by the lock bar case when the key is in an operating position other than the lock position, and even if the key returns to the lock position, the locking action is suspended until the key is pulled out. Therefore, it is possible to reliably prevent an accident in which the vehicle traveling device is locked while the vehicle is running.

The locking device according to the present invention has the above-mentioned configuration, and its operation will now be explained based on the operational explanatory diagrams of FIGS. 4 to 10.

In FIG. 4, the engine start key is in the lock position, the lock bar 12 protrudes from the closed part 10a of the case 10 to the outside of the case 10 due to the biasing force of the spring 18, and the end 12b of the lock bar 12 engages with the steering shaft. The locked state is maintained.

In the illustrated embodiment, the engine start key has three operating positions in addition to the "lock" position: an "accessory" position, an "on" position, and a "start J position", and the key is rotated to each operating position. The desired operating effect can thereby be obtained.

In FIG. 4, the locking portion 12e of the lock bar 12 has separated from the locking end 30a of the holding lever 30 and protrudes toward the steering shaft, and in this state, the locking portion 12e and the locking end 30a are separated. There is no engagement. key 2
8 is pulled out from the cylinder lock, as shown in FIG. 3, the holding lever 30 and the swinging lever 32 are in a position separated from the lock bar 12, as shown by the chain line.

In this state, when the key 28 is inserted into the key groove of the cylinder lock stator 24, the key 28 pushes aside the swing lever 32 and enters the key groove, so that the locking end 30 of the holding lever 30
a is the lock bar 12 as shown by the solid line in FIG.
move forward towards. When the holding lever moves, the locking portion 12e of the lock bar 12 moves downward as shown in FIG. 4, so the locking end 30a does not interfere with the locking portion 12e. FIG. 5 shows the key rotated from the lock position to the accessory position.

As the key rotates, the first operating terminal 22a of the cam 22 raises the arm 12d of the lock bar 12 toward the axis of the lock bar 12, and the lock bar 12 is inserted into the closed portion 10a of the case 10 and the groove 14a of the rotor 14. It is guided and moves upward from the state shown in FIG. 4, and its end 12b separates from the steering shaft. Therefore, the steering shaft is unlocked in the state shown in FIG. At the end of the rotation of the cam 22, the end 12b of the lock bar 12 is removed from the opening 10a, so the further rotation of the cam 22 causes the lock bar 12 to rotate together with the rotor 14 to the position shown in FIG. do. Therefore, in the state shown in FIG. 5, the end 12b of the lock bar 12 is in contact with the inner wall of the case 10, and the lock bar 12 is removed from the position facing the steering shaft through the opening 10a of the case 10. 12 unlocking is reliably held. That is, even if the cam 22 rotates or breaks due to some unexpected accident in this state and the first actuating terminal 22a and the arm 12d of the lock bar 12 are separated, the lock bar 12 remains in the case 1.
It is securely held by the inner wall of 0, and no locking action occurs. In the state shown in FIG. 5, the second operating terminal 22 of the cam 22
b is separated from the protrusion 14b of the rotor 14, and a desired gap is formed between the two. This gap allows idle rotation of the cam 22 when returning the engine start key to the lock position, and allows the lock bar to be brought into the closed portion 10a of the case 10 by the rotation of the terminal end that rotates the key to the lock position. It is suitable for From Figure 4 to Figure 5 Key Moslem times,
As mentioned above, the lock bar 12 moves upward in the figure,
The locking portion 12e of the lock bar 12 can also move, and at this time, the locking end 30a of the holding lever 30 rotates from the position shown in FIG. 4 to FIG.
2e will not collide with the locking end 30a.

As described above, since the holding lever 30 is located inside the cylinder lock rotor 24, the locking end 30a is moved to the cam 2 as the key is rotated.
It rotates with 2. Particularly in the lock position shown in FIG. 4, there is a gap between the first operating terminal 22a of the cam 22 and the arm 12d of the lock bar 12, and when the key is rotated from the lock position to the accessory position, the cam 22 rotates through the gap until it comes into contact with the lock bar, and during this time the locking end 30a can retreat from the movement area of the locking portion 12e. FIG. 6 shows a state in which the engine start key has been moved to the on position, and the lock bar 12 and the rotor 14 rotate within the case 10 as the cam 22 rotates, and the lock bar 12 moves inside the case 10. It is kept unlocked by the inner wall of the

Similarly, FIG. 7 shows the state in which the engine start key has been turned to the start position, and the lock bar 12 and rotor 14 are connected to the cam 2.
2, the lock bar 12 remains in the case 1.
The unlocked position is maintained by the inner wall of 0.

The key is returned from the starting position shown in FIG. 7 to the ON position shown in FIG. There will be no contact.

Therefore, during this rotational movement, the lock bar 12 remains at the same position as the starting position shown in FIG. When the engine start key is further rotated back to the accessory position shown in FIG. rotate at the same time.

However, even in the accessory position of FIG.
The lock bar 12 is maintained at the unlocked position by the inner wall of the case 10. When the engine start key is turned from the accessory position shown in Figure 9 to the lock position shown in Figure 10,
The second operating terminal of the cam 22 contacts the protrusion 14c of the rotor 14 to rotate the rotor 14 and lock bar 12, thereby returning each member to the lock position shown in FIG. 10.

In the locking position shown in FIG. 10, the locking bar 12 is rotated to a position where its end 12b faces the entrance part 10a of the case 10, but in the present invention, the holding lever 3
Since the locking device 30a of No. 0 is in contact with the locking portion 12e of the lock bar 12, as is clear from FIG. It is on hold. When the key 28 is pulled out from the cylinder lock stator 24 from the state shown in FIG. The biasing force of the spring 18 moves it to the position indicated by the chain line in FIG.

As a result, the locking end 30a of the holding lever 30 and the lock bar
12 is disengaged from the locking portion 12e, and the lock bar 1
2 is moved downward by the biasing force of the biasing spring 18, and its end 12b engages with the steering shaft to achieve a locking action. In the illustrated embodiment, by providing a slope on the locking portion 12e of the lock bar 12, the holding lever 30 and the swinging lever 32 are moved by the urging force of the urging spring 18. Lock bar 12 by engaging another biasing spring.
It is also possible to remove the slope provided on the locking portion 12e. As described above, in the illustrated embodiment, the lock bar 12 is held in the unlocked state by the inner wall of the case 10 when the engine start key is rotated to a position other than the locked position. Even if a failure such as a breakage occurs in the mechanism, unnecessary locking of the steering shaft will not occur, and the locking will be controlled in accordance with the attachment and detachment of the engine start key.

A second preferred embodiment of the present invention is shown in FIGS. 11 and 12, and constituent members that are the same or similar to those of the first embodiment are designated by the same reference numerals and their explanations will be omitted.

The characteristic feature of the second embodiment is that, unlike the first embodiment, the lock bar 12 itself directly rotates within the case 10 without requiring a rotor. In the illustrated embodiment, the lock bar 12 is supported by the shaft 20 through its outermost groove 12c, but its outer peripheral surface 12f may be supported by the inner wall of the case 10 and the stopper plate 16. The second actuation terminal 22b of the cam 22 is formed as an end projecting from the cam 22, as shown in FIG. 12, and the actuation terminal 22b engages with the side wall 12g of the lock bar 12. Further, a spring 18 that biases the lock bar 12 toward the steering shaft is inserted into the hole 12a of the lock bar 12, and generates a biasing force between the lock bar 12 and the shaft 20. FIG. 12 shows a cylinder lock mechanism for rotating the cam 22 by the engine starting key, and the rotor 24 of the cylinder lock is engaged with the cam 22. In the second embodiment, the second operating terminal 22b of the cam 22 is connected to the lock bar 12.
The same function as in the first embodiment can be performed except that the second embodiment directly contacts the side wall 12g of the first embodiment.

The lock bar 12 shown by a solid line in FIGS. 11 and 12 shows a state in which the key is inserted into the lock position during engine starting, and the end 12b of the lock bar 12 is connected to the lock bar case 1.
It is pulled into 0. Further, the lock bar 12 shown by the chain line in FIGS. 11 and 12 shows a state in which the engine start key is pulled out at the locked position, and the end portion 1 of the lock bar 12
2b projects toward the steering shaft. In the second embodiment as well, the lock bar 12 always closes its end 1 when the engine start key is in a position other than the lock position.
2b is held by the inner wall of the case 10, and no locking action is performed in the event of a failure.

As described above, according to the present invention, the lock bar is reliably held in the lock bar case when the key is moved to an operating position other than the lock position, and the lock bar remains in place when the key is returned to the lock position. The locking action of the holding lever linked to the key is suspended, and only when the key is pulled out from the cylinder lock, the holding lever separates from the lock bar and the locking action of the lock bar is achieved, eliminating the need for locking the vehicle operating device. This can be reliably prevented.
