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 lock bar is pulled out, 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 to operate. It is placed.

In the conventional device described above, when the lock bar is in the unlocked state, the lock bar is held in the unlocked position by the locking part linked to 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 member, 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 an object of the present invention 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. 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 device 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 enables the lock bar to detach from the vehicle operating device to release the lock, and the lock bar itself to be rotatable 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 the retracted position where it does not face the vehicle operating device, so it is possible to reliably prevent accidents caused by unnecessary locking while driving. Furthermore, the present invention includes an actuation lever that rotates the lock bar in response to removal of the engine start key, so that even when the key is returned to the locked position, the lock bar is rotated back to the position facing the vehicle operating device. The locking action of the lock bar is completely retained by the inner wall of the lock bar case.

When the key is pulled out, the operating lever rotates the lock bar within the case to a position facing the vehicle operating device, and only in this state is the locking action of the lock bar achieved. Preferred embodiments of the present invention will be described below based on the drawings.

1 to 6 show a preferred embodiment in which a lock bar engages and disengages from a steering shaft as a vehicle operating device. Inside the lock bar case 10 is a lock bar 1.
A rotor 14 holding the rotor 2 is rotatably fixed to the shaft.
A stopper plate 1 is provided at one open end of the lock bar case 10.

The rotor 14 has a cylindrical shape, and has a slide groove 14a formed therein, and the lock bar 12 is inserted into the slide groove 14a so as to be movable in the axial 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 pressed and biased toward the outside of the lock bar case 10. 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, and in this state, the end 12b of the lock bar 12
protrudes from the entrance portion 10a of the lock bar case 10. The long groove 12c provided in the lock bar 12 forms a relief part for the shaft 20 supported by the case. A cam 22 is integrally fixed to one end of the shaft 20, and the cam 22 is interlocked with an engine start key through a well-known cylinder lock, and the cam 22 is rotated when the engine start key is turned. The cam 22 is substantially fan-shaped, and one end thereof forms a first operating terminal 22a, and the other end forms a second operating terminal 22b. The first operating terminal 22a engages with the arm 12b of the lock bar 12, and the second operating terminal 22b engages with the protrusion 14b of the rotor 15. A substantially rectangular groove 22c is formed in the central shaft portion of the cam 22, and as shown in detail in FIG. 2, an engaging protrusion 24a provided at the tip of the rotor 24 of the cylinder lock engages with the groove 22c. do.

The cylinder lock rotor 24 is rotatably locked in a stator 26 fixed to the case 10', and the engine starting key 2

As is well known, the rotor 24 has a plurality of tumblers 30 on the circumferential side of the rotor 24, which are aligned and biased in one direction by a spring 32, as shown in FIG. Two recesses 24b are formed along the surface, and an operating lever 34 as shown in FIG. 6 is mounted in both recesses 24b. The actuating lever 34 has a substantially cylindrical shape with a groove along its marl line, and the remaining segment 3
4a is a recess 24b of the rotor 24 as shown in FIG.
It is equipped with a corresponding one. As is clear from FIG. 3, the width of the segment 34a is set to be 4 mm smaller than the width of the recess 24b. Therefore, the operating lever 34 can be rotated by a predetermined angle with respect to the rotor 24. Actuation lever 3
Between the fourth segment 34a and the rotor 24 are the second and fourth segments 34a.
As shown, a spring 36 is installed. Therefore, in the normal case, the actuating lever 34 is operated by the spring 3

Therefore, when the key is inserted by a predetermined key length, the operating lever 34 is inserted through the key until the key holes 34b and 24c of the operating lever 34 and the rotor 24 are aligned, as shown in FIG. Rotated. When the key is inserted, the segment 34a is rotated clockwise by the biasing force of the spring 36 to the position shown in FIG. The key is the key hole 34b, 24c
When the key is removed, the operating lever 34 is rotated counterclockwise by the biasing force of the spring 36 and returns to the state shown in FIG. 4. A locking end 34c is formed at one end of the operating lever 34, and this locking end 34c is connected to the cam 2.
2, and engages with the lock bar 12 directly or indirectly. 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. 1 and 7 to 13. FIG. 1 shows the engine start key in the locked position and pulled out from the cylinder lock mechanism, and as mentioned above, the lock bar 12 engages with the steering shaft (not shown) to lock its rotation. There is.

The actuating lever 34 is then operated as shown in FIG.
The rotor 24 is urged to rotate counterclockwise in all directions, and its locking end 34c is in contact with the protrusion 14b of the rotor 14. When the key is inserted into the cylinder locking mechanism in the locked position shown in FIG.
4 rotates clockwise relative to the trochanter 24, as shown in FIG. 5, and the locking end 34c of the operating lever 34 rotates within the groove 22d of the cam 22, as shown in FIG. and rotor 14

- However, in Fig. 7, the engine start key is in the locked position and the lock bar 12 is in the case 1.
0 to the outside of the case 10 from the opening 10a of the spring 1
The end portion 12 of the lock bar 12 protrudes due to the biasing force of 8.
b engages with the steering shaft to maintain a locked state.

. 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 an r-start position, and the key can be rotated to each operating position. The desired operating effect can thereby be obtained.

FIG. 8 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 toward the mirror of the lock bar 12, and then
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. 7, and the end portion 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 closed portion 10a, so that the lock bar 12 is attached to the rotor 1 by the further rotation of the cam 22.
4 to the position shown in FIG. Therefore, in the state shown in FIG. 8, 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
Since the lock bar 12 is removed from the position facing the steering shaft through the opening 10a, the lock bar 12 is reliably held unlocked. That is, even if the cam 22 rotates or breaks due to some unexpected accident in this state and the first operating terminal 22a and the arm 12d of the lock bar 12 are separated, the lock bar 12 remains in the case. It is securely held by the inner wall of 10 and no locking action occurs. In the state shown in Figure 8,
The second operating terminal 22b of the cam 22 is connected to the protrusion 1 of the rotor 14.
4b, and a desired gap is formed between the two. This gap allows the cam 22 to rotate idly when returning the engine starting key to the lock position, and allows the lock bar to approach the entrance 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 9th
The figure 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 is locked by the inner wall of the case 10. It is kept in a released state.

Similarly, FIG. 10 shows the engine start key turned to the start position, with 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. 1st
The key is returned to the ON position shown in FIG. 11 from the starting position shown in FIG. There's nothing to do.

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 rotated back to the accessory position shown in FIG.
b, but the rotor 14 and lock bar 12 are
Stay at the starting position shown in Figure 0.

When the engine start key is further rotated back to the lock position shown in FIG. 13, the second operating terminal 2 of the cam 22
2b engages with the protrusion 14b of the rotor 14 to rotate the rotor 14 and lock bar 12 simultaneously.

However, even in the locked position shown in FIG. 13, the lock bar 12 is maintained at the unlocked position by the inner wall of the case 10. In FIG. 13, it can be seen that the locking end 34c of the operating lever 34 is in contact with the protrusion 14b of the rotor 14. In this locked position, when the key is pulled out from the cylinder locking device, the operating lever 34 is rotated relative to the rotor 24 by the biasing force of the spring 36, as is clear from FIGS. is transmitted to the protrusion 14b of the rotor 14 via the locking end 34c. That is, the protrusion 14b is rotated by the locking end 34c from the position shown in FIG. 13 to the position shown in FIG.
It protrudes from the opening 10a toward the steering shaft in correspondence with the opening 10a, and a locking action is achieved. Therefore, as is clear from the above description, according to the illustrated embodiment, the key is rotated back to the lock position and when the key is pulled out, the lock bar 1 is moved by the rotational force of the operating lever 34.
2 from being held by the lock bar case 10, and the vehicle operating device can be locked.

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 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 response to removal of the engine start key.

A second preferred embodiment of the present invention is shown in FIGS. 14 and 15, 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 ratchet 20 by its Saicho 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 actuating terminal 22b of the cam 22 is formed as an end projecting from the cam 22, as shown in FIG. 15, and the actuating 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. 15 shows a cylinder lock mechanism for rotating the cam 22 by the engine start 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 is directly connected to the side wall 12g of the first embodiment.

The lock bar 12 shown by a solid line in FIG. 14 shows a state in which the engine start key has been returned to the locked position, and the end portion 12b of the lock bar 12 has been retracted by the lock bar case. Further, the lock bar 12 shown by the chain line in FIG. 14 shows a state in which the engine start key is pulled out at the locked position, and the end portion 12b of the lock bar 12 protrudes toward the steering shaft. In the second 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 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 key is also retained when the key is returned to the lock position. When inserted, the locking action of the lock bar is suspended, and only when the key is pulled out from the cylinder lock, the operating lever rotates to the locking position and the locking action of the lock bar is achieved, eliminating the need to lock the vehicle operating device. This can be reliably prevented.
