Description

[Detailed Description of the Invention] The present invention relates to a steering lock device for a vehicle in which a cylinder lock portion, a steering lock operating portion, and a vehicle switch portion are integrated into a case.

In this type of device, the cylinder lock is large in size, has a large number of parts, and is difficult to assemble, so it is convenient to assemble the cylinder lock separately into a unit and then assemble it into the steering lock device in the final process. Also, with this configuration, if the cylinder lock becomes difficult to rotate or the key is difficult to attach and remove, it is now possible to replace only the unitized cylinder lock instead of replacing the entire steering lock. It is meaningful.

The object of the present invention is to provide a steering lock device having such a unitized cylinder lock, which is particularly easy to assemble.

To explain this with reference to the illustrated embodiment, reference numeral 1 indicates a case, and inside the case 1, there is a cylinder lock 2,
A semicircular cam 4 provided on the outer periphery of the rotor 3 via a rotor 3 connected to and integrated with the rotor of the cylinder lock 2 (this rotor 3 may be provided separately from the rotor of the cylinder lock 2). A steering lock body 5 that engages with the rotor 3 and an electric switch 7 that engages with a pin 6 provided at the tip of the rotor 3 are provided. Reference numeral 8 designates an outer cylinder into which the cylinder lock 2 is inserted, and a locking pin 10 is housed inside the outer cylinder 8 and is urged to protrude outward by a spring 9. An engagement hole 1 that protrudes through the case 1 under normal conditions
1, but when the cylinder lock 2 is rotated to the ACC position, the escape hole 18 provided on the outer periphery of the cylinder lock 2 and the engagement hole 11 match, and the case 1 can be engaged and disconnected from the outside using a tool. When the pin can be pushed in and the rear end of the engagement/disengagement pin 10 is recessed into the escape hole 18, its tip is buried in the outer cylinder 8 and disengaged from the case 1.

The semicircular cam 4 is formed into a protrusion 4a as shown in FIG. 2, and the protrusion 4a has an axial through groove 4b as shown in FIG. Furthermore, the case 1 is provided with a locking protrusion 12 that engages with the rear wall 4c of the projecting strip 4a and can be inserted through the through groove 4b.

Further, an inclined surface 13 is formed at the tip of the insertion pin 6, and the height of the inclined surface 13 is the same as the remaining V-shaped notch surface 14 of the semicircular cam 4 provided on the rotor 3. The inclined surface 13 engages with the upper surface 17 of the engagement hole 16 of the lock body 5, which is lowered by the spring 15, when the outer cylinder 8 is installed in the case 1 as described later. It is formed so that the body 5 can be pulled up against a spring 15.

To explain its operation, when assembling the steering lock, especially when you want to assemble or replace the outer cylinder 8, which is assembled into a unit by incorporating the cylinder lock 2, with the cylinder lock 2 already assembled in the locked position as shown in FIG. When the cylinder lock 2 is rotated to the ACC position, the locking pin 10 aligns with the relief hole 18 of the cylinder lock 2, and the locking protrusion 12 of the case 1 aligns with the protrusion 4.
By pushing the locking pin 10 so that it is disengaged from the locking hole 11 of the case 1, the outer cylinder 8 can be pulled out from the case 1 and disengaged from the rotor 3. The lock body 5 is urged by the spring 15 and falls downward. Even in this state, a unitized cylinder lock can be assembled, and the cylinder lock 2 is assembled into a unitized outer cylinder 8, which is inserted into the engagement hole 16 of the fallen lock 5 and the outer periphery of the rotor 3 is inserted. To engage the lock, rotate the cylinder lock 2 inside the outer cylinder 8 to the lock position,
V-shaped notch surface 14 of rotor 3 and locking hole 1 of lock body 5
When the inserting pin 6 is inserted so that the upper surface 17 of the locking hole 16 is aligned with the upper surface 17 of the locking hole 16, the inclined surface 13 at the tip of the inserting pin 6 slides against the upper surface 17 of the locking hole 16, and the lock body 5 is pulled up against the spring 15 to open the notch. The surface 14 and the upper surface 17 of the locking hole 16 are made to match. In this state, the locking protrusion 12 provided on the case 1 comes into contact with the front wall of the protrusion 4a to restrict the insertion of the outer cylinder 8, but then the cylinder lock 2 is
When rotating to the ACC position, the locking protrusion 12 engages the protrusion 4
The outer cylinder 8 is further inserted beyond the locking protrusion 12 in order to fit into the through groove 4b of a. At this time, the locking pin 10 is also positioned above the relief hole 18 of the cylinder lock 2, so the locking pin 10 is inserted into the case 1 with the locking pin 10 pushed into the outer cylinder 8, and the locking pin 10 is inserted into the case 1.
When it reaches the position of the locking hole 11, it protrudes and is engaged with the locking hole 11, completing the installation.

In this way, according to the present invention, the rotor 3 integrated with the cylinder lock 2 incorporated in the outer cylinder 8 as a unit type is provided with an inclined surface 13 at its tip to lift up the fallen lock 5, and the outer periphery of the rotor 3 is The semicircular cam 4 provided to engage with the lock body 5 interferes with the protrusion 12 provided on the inner wall of the case 1 at the lock position.
Since it is formed on the protrusion 4a that allows passage at the ACC position, it is not only easy to assemble the outer cylinder 8 to the case 1, but also easy to replace only the outer cylinder 8 in which the cylinder lock 2 is incorporated. Even if a problem occurs with the cylinder lock, there is no need to replace the entire cylinder lock, making repairs easy.Also, the outer cylinder 8 is equipped with a locking pin 10 that engages and disconnects from the case 1 only when the cylinder lock 2 is in the ACC position. is locked by the double engagement between the locking pin 10 and the protrusion 12 that engages with the protrusion 4a, and furthermore, in the locked position where the lock is turned and the car is left, the cylinder lock 2 can be prevented from being pulled out. have
