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 with 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 problems, and its purpose 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. Therefore, it is an object of the present invention to provide a vehicle operating device locking device that can prevent an unnecessary locking accident of the operating position that occurs when the vehicle is running.

In order to achieve the above object, the present invention allows the lock bar to be detached from the vehicle operating device to release the lock, and the lock bar itself can be rotated within the lock bar case by rotation of the engine start key. Features.

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. According to the invention, only when the engine start key is rotated to the lock position.

The locking bar can engage the vehicle operating device and only in this state can a locking effect be obtained. Preferred embodiments of the present invention will be described below based on the drawings.

FIG. 1 shows a preferred embodiment in which a lock bar engages and disengages from a steering shaft as a vehicle operating device. A rotor 14 that holds the lock bar 12 is secured inside the lock bar case 10 so that it can be rolled around. A stopper plate 16 is fixed to one open end of the lock bar case 10, and the rotor 14 is connected to the case 10 and the stopper plate 16.
It is rotatably supported. The rotor 14 has a cylindrical shape and has a sliding groove 14a formed therein, into which the lock bar 12 is slidably inserted in the scale direction of the lock bar. A biasing spring 18 is provided between the inner wall of the rotor 14 and the spring receiving hole 12a of the lock bar 12, and the lock bar 12 is attached to the lock bar case 1.
0 is biased toward the outside. The state shown in FIG. 1 shows a state in which the lock bar 12 is engaged with a steering shaft (not shown) to lock the steering shaft. It protrudes from the portion 10a or 4. The long groove 12c provided in the lock bar 12 is connected to the case 1.
The lock bar 12 is guided in the correct direction by engaging the supported shaft 20. 2 in FIG. 1 is attached to one end of the shaft 20.
The cam 22 shown by the dotted chain line is integrally fixed, and the cam 2
2 is interlocked with an engine start key through a well-known cylinder lock, and the cam 22 is rotated with the rotation of the engine start key. The cam 22 is substantially fan-shaped, and one end of the cam 22 forms a first operating terminal 22a, and the other end forms a second operating terminal 22b. The first actuation terminal 22a engages with the arm 12d of the lock bar 12, and the second actuation terminal 22b engages with the protrusion 14b of the rotor 14. 0 The locking device according to the present invention has the above configuration, and its operation will be explained next.

In FIG. 1, the engine start key is in the lock position, the lock bar 12 protrudes outward from the case 10 from the entrance 10a of the case 10 due to the biasing force of the spring 18, and the end 12b of the lock bar 12 is connected to the steering shaft. It is engaged and 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" position, and the key is rotated to each operating position. The desired operating effect can thereby be obtained.

FIG. 2 shows the key rotated from the lock position to the accessory position. As the key turns, cam 2
The first operating terminal 22a of the lock bar 12 is connected to the arm 12 of the lock bar 12.
d in the axial direction of the lock bar 12, and
are the entrance part 10a of the case 10 and the groove 14a of the rotor 14.
The end portion 12b moves upward from the state shown in FIG. 1, and its end portion 12b separates from the steering shaft. Therefore, the steering shaft is unlocked in the state shown in FIG. At the end of rotation of the cam 22, the end 1 of the lock bar 12
2b is disengaged from the opening 10a, further end rotation of the cam 22 causes the lock bar 12 to disengage from the rotor 14.
It rotates to the position shown in Figure 2. Therefore, in the state shown in FIG. 2, 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 closed part 10a of the case 10, so that the lock bar 12 is not locked. The bar 12 is reliably held unlocked. That is, in this state, due to some unexpected accident, the cam 22 rotates or breaks, and the first operating terminal 2
2a and the arm 12d of the lock bar 12 are separated, the lock bar 12 is securely held by the inner wall of the case 10,
No locking action occurs. In the state shown in FIG. 2, the second operating terminal 22b of the cam 22 is connected to the protrusion 14b of the rotor 14
A desired gap is formed between the two. This gap allows the lock cam 22 to rotate idly when the engine starting key is returned to the lock position, and the lock bar is moved to the case 1 by the rotation of the terminal end that rotates the key to the lock position.
This is suitable for facing the closed portion 10a of 0. FIG. 3 shows a state in which the engine start key has been moved to the on position, and the lock bar 12 and rotor 14 rotate within the case 10 as the cam 22 rotates, and the lock bar 12 moves to the case 1.
It is kept unlocked by the inner wall of 0.

Similarly, FIG. 4 shows the engine start key rotated to the start position, and the lock bar 12.

The motor 14 is rotated by the cam 22, and the lock bar 12 is still maintained at the unlocked position by the inner wall of the case 10. The key is returned from the starting position shown in FIG. 4 to the on position shown in FIG.
2d or the protrusion 14b of the rotor 14.

Therefore, during this rotation, the lock bar 12 remains in 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 shown in Figure 6,
The lock bar 12 is maintained at the unlocked position by the inner wall of the case 10. When the engine start key is further rotated from the state shown in FIG. 6 to the lock position shown in FIG. 1, the rotor 14 and lock bar 12 are returned to the state shown in FIG. When the end 12b matches the opening 10a of the case 10, the lock bar 12
The biasing spring 18 moves downward, and the end 12b of the lock bar 12 engages with the steering shaft to perform a locking action.

As described above, in the illustrated embodiment, when the engine start key is rotated to a position other than the locked position, the lock bar 12 is held in the unlocked state by the inner wall of the case 10, so that the cylinder locking mechanism and other parts Even if a failure such as a breakage occurs in the mechanism, unnecessary locking of the steering shaft will not occur.

A second preferred embodiment of the present invention is shown in FIGS. 7 and 8, and constituent parts that are the same or similar to those in the first embodiment are given 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 on the shaft 20 by its long groove 12c;
2e may be supported by the inner wall of the case 10 and the stopper plate 16. The second operating terminal 22b of the cam 22 is the eighth
As shown in the figure, the actuating terminal 22b is formed as an end protruding from the cam 22, and the actuating terminal 22b is connected to the side wall 12 of the lock bar 12.
engages with f. Further, the spring 18 that urges the lock bar 12 toward the steering shaft is inserted into the hole 1 of the lock bar 12.
2a to generate a biasing force between the lock bar 12 and the shaft 20. FIG. 8 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. Second
In this embodiment, the same operation as in the first embodiment can be performed except that the second operating terminal 22b of the cam 22 directly contacts the side wall 12f of the lock bar 12.

Lock bar 12 and cam 2 shown by chain lines in FIGS. 7 and 8
2 indicates the state where the engine start key is in the lock position,
An end 12b of the lock bar 12 projects toward the steering shaft. Further, the lock bar 12 shown by the solid line in FIGS. 7 and 8 is such that the first actuating terminal 22a of the cam 22 presses the arm 12d of the lock bar 12 upwards due to the rotation of the engine start key, and the lock bar 12 is case 1
0 is shown when it is removed from the closed portion 10a. Second
In this embodiment as well, when the engine start key is in a position other than the locked position, the end 12b of the lock bar 12 is always held by the inner wall of the case 10, and no locking action is performed in the event of a failure.

As explained above, according to the present invention, the lock bar itself rotates as the engine start key rotates, further rotates from the lock standby position, and the lock bar case maintains the unlocked state. Since the release position is searched, it is possible to reliably prevent an unnecessary locking action from occurring even if a failure such as a breakage occurs in the engine start key mechanism, cylinder lock mechanism, or the like.
