Description

The invention relates to technical means preventing theft of a car, in particular to means preventing access to the ignition switch and steering mechanism.

Known anti-theft device that prevents the unauthorized use of the vehicle’s ignition lock, including a safety assembly that covers the ignition, and a bracket with a code mechanism located in it with a locking key, and the safety assembly is made with the ignition lock body in one piece (RF patent for utility model No. 13548 , published: 04/27/2000, patent holder: Alenkin Yuri Kirillovich, IPC: B60R 25/04)

The disadvantage of this technical solution lies in the complexity of installation, and the use of a combination lock leads to a higher cost of construction.

The closest in technical essence and the achieved effect is the BARRAKUDA Q7 KALINA-PRIORA steering shaft lock containing a steel casing, a high alloy steel protective washer installed between the lock cylinder and the cover, an armored cover that reliably protects the contact group and access to the secret part of the lock, fastening a stall bolt, and on some versions, starter circuit protection is installed.

The disadvantage of this technical solution lies in the complexity of the installation, because during installation, it is necessary to disassemble the protected mechanisms, respectively, the complexity of the replacement in the event of a breakdown, as well as the standard lock, is poorly protected from the keyhole.

The objective of the claimed utility model is to increase the reliability of protection of the device from the side of the keyhole, as well as to increase the usability of the device for protecting keyholes.

The technical result is to improve operational characteristics and, as a consequence, burglary resistance.

The technical result is achieved in that the anti-theft device comprising a lock, a latch is made of two detachable parts, the first part contains a connecting element and a fixing element, a safety assembly made of two parts, a cover covering the end face of the safety assembly and made with a flange on which is installed in the second part using a valve, in addition, a lock is made in the housing of the second part.

The design of the proposed technical solution is shown in the drawings, where:

figure 1 - the first part assembly;

figure 2 is a first part, an explosion diagram;

figure 3 is a second part, an explosion diagram;

4 is a second part, a bottom view, the lock position is “open”, the key position is “closed”;

5 is a second part, a bottom view, the lock position is “closed”, the key position is “open”;

6 is a second part, side view, in section;

Fig.7 is a second part, side view, in section.

The claimed technical solution can be implemented in the design of an anti-theft device, including a lock 1, a valve 2, a connecting element 3, a fixing element 4, a safety assembly 5, a pin 6, a cover 7, a flange 8, a housing 9, a plug with a damper 10, bolts 11, a disk trap 12, liners 13, balls 14, springs 15, screws 16, screw 17, liner 18.

The anti-theft device is arranged and operates as follows.

The first part is installed as follows: the safety unit 5 is assembled from two parts, which are connected, for example, by means of a loop coupling through the axles 6, after which the connecting element 3, which is made, for example, in the form of a bolt, is rigidly connected to the safety unit 5. Then, the connecting the element 3 is closed with a plug with a damper 10, while the plug and, accordingly, the connecting element 3 is fixed with a fixing element 4, made in the form of a steel rod. A flange 8 is attached to the connected parts of the safety assembly 5 with a cover 7 using bolts 11 (any other fasteners can also be used instead of bolts 11). In this case, the flange 8 closes the access to the fixing element 4. The flange 8 is used to fasten the second part, which closes the access to the ignition cylinder of the vehicle and the bolts 11. In this case, the flange 8 has an internal groove and four grooves for engagement with the protection of the secret mechanism, referred to in this description - "The second part."

The second part is as follows. The disk-trap 12 is designed to protect the lock 1. The liner 13 holds the lock 1 from angular rotation and in the axial direction, also the liner 18 hooks through the outer groove holds the valve 2 in the axial direction. Balls 14 with springs 15 create a fixed position of the valve 2 in extreme positions, for this purpose, holes are made in the valve 2 (see Fig. 7). The screws 16 (also any other fasteners can be used instead of the screws 16) fasten the liners 13 and 18 in the lock protection housing 9, the screw 17 restricts the locking angle of the valve 2 - 45 degrees. To install the screw 17 in the valve 2, a groove and a radius selection are made (see Figure 5). Instead of a screw 17, any other stop can be used, for example, a limiter of the angle of rotation can be located in the larva of the lock 1. A lock 1 is installed in the housing 9, by means of which the valve 2 is controlled.

The second part (protection of the secret mechanism) is attached to the first part (armor protection) when the protrusions on the valve 2 and the inserts 13 coincide, while the anti-theft device is in the “Open” position. In the "Open" position (see Figure 4), the protrusions of the valve 2 are combined with the grooves of the flange 8, then by turning the key in the lock 1 of the second part, the valve 2 is rotated by an angle, for example, of 45 degrees (you can rotate it 90 times) () see FIG. 5) in this case, the protrusions of the valve 2 along the groove in the flange 8 also rotate by the same angle relative to the groove of the flange 8. The inserts 18 in the grooves of the flange 8 do not allow the second part to be rotated relative to the first part (armor protection) and alignment of the ledges of the valve 2 dismantle the second part. In the position of the second part "Closed", you can get the key from the lock 1 - the protection is installed. The second part can be dismantled only by turning the key to the “Open” position by the actions opposite to those described earlier.

Thus, the application of the utility model allows to simplify the installation of the anti-theft device due to the use of the elements of mutual engagement and the connecting element, to improve the protection of the ignition switch through the use of a removable device.
