Description

[Detailed description of the invention] This invention locks the steering shaft unrotatably by protruding the locking member when the key is removed and removed, while the locking link moves in a seesaw movement when the key is inserted and the cylinder lock is rotated. This invention relates to an improvement in a steering lock device for a motor vehicle in which an end portion engages with a locking member to hold the locking member in an unlocked position.

Generally, such a steering lock device has a cylinder outer 1 as shown in FIGS. 1 and 2.
while inserting the cylinder lock 2 into the lock link 3.
The lock link 3 was housed in the cylinder outer 1 by fitting the shaft 4 provided in the cylinder outer 1 into the groove 6 formed in the upper divided portion 5 of the cylinder outer 1, and the plate 9 was attached to the upper part by fitting the spring 7 into the groove 8. Later, there is one in which the cylinder outer 1 is assembled into a lock body 10 and a dowel pin 11 is driven in and fixed therein.

However, in this case, the cylinder outer 1 is fixed by driving a dowel pin 11 so that it cannot be easily removed from the lock body 10 to prevent theft, and the lock link 3 and spring 7 assembled to the cylinder outer 1 are fixed. Plate 9 is caulked to prevent it from coming off, so
Jigs and tools were required for each assembly process. In addition, there were many parts, and the overall weight was heavy.

This idea was created in view of the above problems.
The central part of the lock link and the spring are housed in a case made of resin material, and this case is assembled from the rear opening side of the lock body for ignition switch assembly, eliminating the need for a cylinder outer and allowing parts to be assembled. The present invention provides a steering lock device for an automobile that can reduce the number of jigs and tools, reduce the number of parts, and reduce weight.

The present invention will be described in more detail below with reference to the drawings.

In FIG. 3, reference numeral 12 denotes a lock body, and the lock body 12 includes a cylinder lock 13 and a lock link 1.
An ignition switch 18 is assembled to a case 16 housing a spring 15 and a locking member 17, and a rear opening 12a. cylinder lock 1

When the cylinder lock 13 is removed and removed, the cylinder lock 13 protrudes from the outer peripheral surface of the lock body 12 into the groove 12b of the lock body 12.
When the key 19 is inserted, it moves to the outer peripheral surface of the cylinder lock 13 and locks the cylinder lock 1.
Lock plate 21...21 that allows rotation of 3
A cam part 13a for moving the locking member 17 to the unlock position is integrally formed in the middle part, and a connecting part 13b for rotating the ignition switch 18 in accordance with the rotation of the key 19 is integrally formed in the rear end part. ing. The case 16 is formed into a roughly U-shape as shown in FIG.
6d, and a cover 16e having a bendable thin wall portion (not shown) on the side wall 16a.
A spring 1 is formed on this cover 16e.
A protrusion 16f that fits into the lock 5 and a pair of locking protrusions 16g are formed. A recess 16h into which the cover 16e is fitted is formed in the side wall 16b, and a pair of engagement holes 16i are provided in the recess 16h. The tip 14a of the lock link 14 housed in the case 16 fits into the recess of the cylinder lock 13 when the key 19 is removed due to the pressing force of the spring 15, and the rear end 14b is lifted, and when the key 19 is inserted, the tip of the lock link 14 14a is pushed up to the outer peripheral surface of the cylinder lock 13 in conjunction with the slider 20, and the rear end 14b is lowered. The locking member 17 is a spring 22 in FIG.
The cam portion 1 of the cylinder lock 13 is biased to the left by
The locking portion 17a of the locking member 17 moves in the left-right direction in accordance with the rotation of the locking member 17 when the locking member 3a is rotated.
The lock portion 17a protrudes from the opening hole 12c formed in the lock body 12 to lock the steering shaft (not shown), and in the unlocked position, the lock portion 17a enters the opening hole 12c of the lock body 12 to lock the steering shaft (not shown). Set to unlocked state. That is, the rear end 14b of the locking link 14 is separated from the locking member 17 when the key 19 is not inserted, and the rear end 14b of the locking link 14 is separated from the locking member 17 when the key 19 is not inserted.
9 is inserted, the rear end 14b is lowered and comes into contact with the upper surface 17b of the locking member 17, and the key 19 is rotated to rotate the cam portion 13a of the cylinder lock 13 and move the locking member 17 to the unlock position, as shown in FIG. The upper surface 17b of the locking member 17 as shown in FIG.
It is configured to engage with a groove 17c formed in the groove 17c. This operation causes the lock link 14 to
When the key 19 is inserted, the locking member 17 is held in the unlocked position and the steering shaft is unlocked, and when the key 19 is removed, the locking member 17 is released and moved to the locked position, and the steering shaft is moved to the locked position. This locks the shaft.

Next, a method of assembling the lock link 14 will be explained.

As shown in FIG. 4, the lock link 14 is provided with a shaft 14c, and this shaft 14c is connected to the case 1
Grooves 16c formed in both side walls 16a, 16b of 6,
16d, the tip 1 of the lock link 14
4a and the rear end 14b are accommodated in a state where they protrude from the case 16 so as to be able to see-saw. Then, the spring 15 is fitted into the groove 14d formed in the lock link 14 housed in the case 16.
When the cover 16e is closed with the protrusion 16f formed on the cover 16e of No. 6 fitted into the spring 15, the lock link 14 and the spring 15 are housed in the case 16 as shown in FIG. This case 16 is then attached to the lock body 12 shown in FIG.
The case 16 is inserted from the opening 12a for assembling the ignition switch into the case accommodating portion 12d formed in the case 16.
Insert. After that, the cylinder lock 13, the locking member 17, and the mounting plate 23 were assembled, and then the caulking protrusions 12e, 12f formed on the lock body 12,
12g are bent and caulked, and the case 16 is prevented from coming off by the outer circumference of the cam portion 13a of the cylinder lock 13.

As is clear from the above description, according to the present invention, a lock link and a spring are housed in a case made of a resin material so as to be able to see-saw, and the case and cylinder lock are inserted into an opening for assembling an ignition switch. Since it is assembled from the beginning, there is no need to separately provide a cylinder outer, so the number of assembly jigs and parts can be reduced and the weight can be reduced. In addition, the front part is not assembled with the cylinder outer like in the conventional example, but is formed integrally, and the cylinder lock is usually exposed because it is assembled through the opening for installing the ignition switch in the lock body. Since the cylinder lock and other parts cannot be removed from the key insertion direction, theft prevention and safety can be improved.

Furthermore, since the lock link and spring can be housed and held in the case and then assembled through the opening of the lock body, highly efficient assembly can be easily achieved without the need for special jigs and tools.
