Description

  The present invention relates to a technology related to an anti-theft device for automobiles, and more particularly to a device related to a device intended to prevent theft by suppressing the turning of the steering by locking the steering.

  Many anti-theft devices for automobiles have been proposed in the past.For example, there is one that prevents the steering wheel from turning by biting an iron bar with a key device on the steering wheel. As shown in Patent Document 1, an electromagnetic lock device is attached to a seat belt buckle of an automobile and linked with a keyless entry device for reasons such as that there is a place for storage, poor appearance, etc. The tongue plate can be inserted into and removed from the buckle only when the locking device is unlocked, and an anti-theft belt such as a wire is attached to the tongue plate, and the tongue plate is attached to the steering wheel after the belt is wound around the steering wheel. Insert into the buckle and lock to prevent the steering from turning and prevent theft of the car The devices have been proposed.

  However, since the anti-theft device is linked to the keyless entry device, there is a problem in that if the car is forgotten to be locked, the anti-theft device cannot be used.

  Accordingly, an object of the present invention is to provide an anti-theft device that can be used even when a car is forgotten to be locked, in order to solve the above problems.

  In the anti-theft device for restraining the turning of the steering by locking one end of the wire to the steering and fixing the other end to the vehicle seat belt buckle, the tongue plate fitted to the vehicle seat belt buckle, and the tongue A locking device for fixing the plate, a push rod for pushing the release button of the seat belt buckle, and a wire for locking to the steering, and the tongue plate and the push rod are arranged inside the box Thus, the antitheft device for a vehicle is provided, wherein the box covers the release button of the seat belt buckle when the tongue plate is fitted to the seat belt buckle.

  Since the anti-theft device according to the present invention fixes the steering, the rotation of the steering more than a certain amount is suppressed and the automobile cannot be operated, so that the theft can be prevented.

  The anti-theft device according to the present invention is lightweight and can be easily attached, and there is no problem with storage. In addition, it looks good and can effectively prevent theft of automobiles.

  Since the main body and the wire are configured to be detachable, actions such as winding around the steering wheel can be easily performed. Further, the fixing and fixing of the wire and the main body and the tongue plate 6 included in the main body can be easily performed by attaching and detaching the same.

  The present invention will be described in detail with reference to the drawings. FIG. 1 shows a perspective view of the anti-theft device according to the present invention, and FIG. 2 shows a cross-sectional view of the main body of the anti-theft device according to the present invention. In particular, (A) shows a sectional view when locked, and (B) shows a sectional view when unlocked. A perspective view of the main body at the time of locking is shown in FIG. 3A, and a perspective view of the main body at the time of unlocking is shown in FIG. FIG. 4 shows an assembly drawing of main parts, and FIG. 5 shows a usage pattern.

  As shown in FIGS. 3 and 4, the anti-theft device 1 of the present invention includes a tongue plate 6 fitted to a vehicle seat belt buckle 3, a lock device 10 for fixing the tongue plate 6, a seat It consists of a push rod 7 for pressing the belt buckle release button 4, a box (main body 9) in which the tongue plate 6 and the push rod 7 are arranged, and a wire 2 for winding around the steering wheel 8.

  As shown in FIG. 4, when the tongue plate 6 is inserted into the joining member 6A with the wire tip 2A, the joining member 6B with the spring 12, and the seat belt buckle 3, the tongue plate 6 is engaged with the buckle. It has a hole 6C.

  As shown in FIG. 2A, when the wire tip 2A is inserted from the wire insertion hole 11, the joining member 6A and the tip 2A come into contact with each other. When locked, the cylinder 10A of the locking device fits into the constricted portion of the tip 2A, and the wire 2 cannot be pulled out from the main body 9. That is, the slide of the tongue plate 6 toward the wire side is restrained. Further, as shown in FIG. 3A, when 6A is in contact with the end of the insertion hole 15A of the pressing member 15, sliding of the tongue plate 6 toward the buckle side is also restrained. The tongue plate 6 is fixed.

  When the lock is released, as shown in FIG. 2B, the cylinder 10A is retracted into the lock device 10, so that the wire 2 can be pulled out from the main body 9, and the tongue plate 6 can be slid.

  In addition, a joining member 6B with a spring is provided at the end of the tongue plate 6 on the wire side. When the joining member 6B presses the spring 12, the tongue plate 6 slides smoothly when the lock is released. In addition, it is preferable to provide the guide 16 in the lower cover 14 which comprises the main body 9 so that a spring may expand and contract in a predetermined direction.

  The main body 9 is a box and is covered with an upper cover 13 and a lower cover 14. Inside the main body 9, a tongue plate 6, a push rod 7, a spring 12, and the like are arranged. The tongue plate 6 provided in the main body 9 is usually provided with a portion having the same shape as that inserted as the tongue plate of the seat belt on the seat belt buckle 3 for an automobile. The tongue plate 6 is shown in FIG. Then, it is inserted into the tongue plate insertion opening 5 provided in the seat belt buckle 3. Then, the lock mechanism (not shown) of the buckle 3 and the hole 6C are fitted, and the main body 9 is fixed to the seat belt buckle 3.

  As described above, when the tongue plate 6 is inserted into the seat belt buckle 3 and the locking device 10 for fixing the movement of the tongue plate 6 is operated, the protrusion (the protrusion of the buckle 3 ( (Not shown) is caught and the main body 9 portion cannot be pulled out of the seat belt buckle 3. Since the release button 4 is covered with the main body 9, it cannot be pushed from the outside, and the antitheft device 1 cannot be removed.

  When it is desired to remove the main body 9 from the seat belt buckle 3, the locking device 10 is first released and the tongue plate 6 is opened. Thereafter, when the main body 9 is pushed to the buckle side, the push rod 7 pushes the release button 4, so that the projection inside the seat belt buckle 3 is released and the tongue plate 6 can be detached from the seat belt buckle 3. In addition, since the spring 12 is provided, the detachment from the seat belt buckle 3 becomes smooth.

  In addition, although the mechanism conventionally used can be used for the locking device 10, in the Example of this invention, the key structure is employ | adopted and the mechanism locked by the cylinder 10A is employ | adopted.

  The wire 2 is configured to be detachable from the main body 9 so that the wire 2 can be easily wound around the steering wheel 8. As shown in FIG. 5, one end of the wire is preferably formed in a ring shape. As shown in FIG. 5, after winding the wire around the steering wheel 8, the wire is passed through the ring 2B portion to the wire connection hole 11 of the main body 9. Insert and lock. As the wire, a commonly used wire can be used, but it goes without saying that a material having strong resistance such as carbon fiber or synthetic resin can be used other than the wire.
