Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has an object of providing a steering lock device, and more particularly, a steering lock device which can be mounted on a tilt type steering shaft capable of adjusting a tilt angle of a steering shaft.

[0002]

2. Description of the Related Art In order to apply a steering lock device for locking a steering shaft having a tilt structure with an adjustable mounting angle to the tilt structure, for example, Japanese Patent Publication No. 62-50.
As disclosed in Japanese Patent Laid-Open No. 95, a structure is known in which a space between an insertion opening portion of a steering lock device and an installation hole provided in an instrument panel is closed by a shielding material that can follow the vertical movement of the steering lock device. .. In addition, JP-A-63-4
Japanese Patent No. 8350 discloses a steering lock device in which a housing portion is rotatably supported so as to correspond to a tilt structure.

[0003]

However, Japanese Patent Publication No. 62-5095 does not show a concrete structure as to how the fixed steering lock device can actually move. In addition, JP-A-63-483
The structure disclosed in Japanese Patent Publication No. 50 has a drawback that the axial line of the key cylinder incorporated in the steering lock device is bent, so that the structure is complicated and the resistance against breakage is small. The present invention solves the above-mentioned drawbacks and has a structure in which the locking rod is connected to the hanger via the link member and the sleeve of the frame is rotatable, so that the structure is relatively simple and has a large resistance to breakage. An object of the present invention is to provide a steering lock device having the above.

[0004]

According to the steering lock device of the present invention, the locking rod is moved to the lock position and the unlock position for engaging and disengaging with the steering shaft, and the locking rod is actuated via the hanger. It is provided with a connected key cylinder, a link member for connecting the locking rod to the hanger, and a sleeve having a hole for accommodating the locking rod and rotatably provided on the frame. The locking rod can move between a locked position and an unlocked position while being inclined with respect to the central axis of the hanger. The link member is pivotally attached to the hanger by the first pin, and is pivotally attached to the locking rod by the second pin. The sleeve is pivotally attached to the frame by the third and fourth pins. The central axes of the key cylinder, the locking rod and the steering shaft are substantially on the same plane. The frame 12 can rotate around the locking rod.

[0005]

Since the locking rod can move between the locked position and the unlocked position in a state of being inclined with respect to the central axis of the hanger, the mounting angle of the steering lock device can be smoothly adjusted when adjusting the mounting angle of the steering shaft. Can be adjusted.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of a steering lock device according to the present invention will be described below with reference to FIGS.

As shown in FIG. 1, the steering lock device 10 is attached to the steering shaft 7. As shown in FIG. 8, the steering lock device 10 has a frame 12 for accommodating the key cylinder 11 and a slot 14a axially attached to the end 15 of the frame 12 and accommodating the locking rod 13. -Bus 14 and. The locking rod 13 is used to rotate and key the key cylinder 11.
When the steering wheel 7 is removed, the recess 7a of the steering shaft 7
(FIG. 3) The lock position for engaging and disengaging (FIG. 8)
And FIG. 9) and unlocked positions (FIGS. 10 and 11). As clearly shown in FIG. 2, the hanger 18 is a key.
A driven portion 18a with which the cam portion 11a contacts the cylinder 11;
The connector 18b is connected to the driven portion 18a. The driven portion 18a has a pressing surface 21 that is pressed by a spring 19 arranged between the lid 20 fixed to the frame 12 and the driven portion 18a. A hook portion 22 is formed below the driven portion 18a. The connector 18b has a head portion 23 to be engaged with the hook portion 22, a neck portion 24 formed in the lower portion of the head portion 23, and a hole portion 25 provided in the lower portion of the neck portion 24.

The link member 30 has a first hole 31 and a second hole 32. The locking rod 13 has a slit 33 for receiving the link member 30 and a hole 34 orthogonal to the slit 33. Hole 2 of connector 18b
5 and the first hole 31 of the link member 30 have the first pin 41
Is inserted, and the connector 18b and the link member 30 are axially attached. Further, the second pin 42 is inserted into the hole 34 of the locking rod 13 and the second hole 32 of the link member 30, so that the locking rod 13 and the link member 30 are axially attached. Further, as shown in FIG. 3, the sleeve 14 is connected to the end portion 1 of the frame 12 by the third pin 43 and the fourth pin 44.
5 is pivoted. The third pin 43 and the fourth pin 44 are urged by the springs 45 and 46 into the long grooves 47 and 48 of the sleeve 14, respectively. Therefore, the long grooves 47, 48
The sleeve 14 can rotate with respect to the frame 12 within a range in which the third pin 43 and the fourth pin 44 can move (FIGS. 5 and 7). As shown in FIGS. 3, 6 and 7, the central axes of the first to fourth pins 44 may be arranged on the same plane. The central axes of the key cylinder 11, the locking rod 13, and the steering shaft 7 are substantially on the same plane.

In the above construction, in the locked state where the proper key is not inserted in the key cylinder 11, the locking rod 13 is in the lock position protruding from the sleeve 14 as shown in FIG. When the steering shaft 7 is rotated when the locking rod 13 is in the lock position, the link member 30 can rotate around the first pin 41 with respect to the connector 18b, as shown in FIG. At this time, the sleeve 14 rotates around the third pin 43 and the fourth pin 44. Therefore, the locking rod 1
Steering lock device 1 even when 3 is in the locked position
The angle of the steering shaft 7 can be changed with 0 attached. Regular key on the key cylinder 11
And the key cylinder 11 is rotated, the locking rod 13 is moved to the sleeve 14 as shown in FIG. 8 or 9.
It is in the unlocked position retracted inside. When the steering shaft 7 is rotated when the locking rod 13 is in the unlocked position, the locking rod 13 is attached to the link member 30 and the second pin 42 which is pivotally attached, as shown in FIG.
You can rotate around. At this time, the sleeve 14 rotates around the third pin 43 and the fourth pin 44. Therefore, even if the locking rod 13 is in the unlocked position, the angle of the steering shaft 7 can be changed with the steering lock device 10 attached.
Further, the link member 30 is connected to the connector 18 by the first pin 41.
The locking rod 13 is connected to the second pin 42 by the second pin 42.
11 and the unlock position of FIG.
It is possible to move the locking rod 13 smoothly even between the locking position of the locking rod 13 and the locking position. In short, in this embodiment, the sleeve 14 can change the angle of the locking rod 13 with respect to the hanger 18 within a plane including the central axes of the key cylinder 11 and the steering shaft 7. Also,
Since the third pin 43 and the fourth pin 44 are arranged in the long grooves 47, 48 of the sleeve 14, the frame 12 can be rotated around the locking rod 13.

The embodiments of the present invention are not limited to the above-mentioned embodiments, and can be modified. For example, the hanger 18 including the driven portion 18a and the connector 18b can be integrally formed. Further, a plurality of link members 30 may be connected between the hanger 18 and the locking rod 13. Sleeve 1
The four long grooves 47 and 48 may be formed as round holes so that the frame 12 cannot rotate around the locking rod 13.

[0011]

Since the locking rod can move between the lock position and the unlock position in a state of being inclined with respect to the central axis of the hanger, the antitheft effect of the steering lock device having a large strength against breakage is not diminished. Moreover, when adjusting the mounting angle of the steering shaft, the mounting angle of the steering lock device can be smoothly adjusted.
