Description

Mechanical interlock for vehicles

The utility model relates to the field of motor vehicles and can be used in mechanical anti-theft devices to prevent the unauthorized use, theft or theft of vehicles.

Known mechanical lock for vehicles, containing a lock mounted on a plate in the immediate vicinity of the gear shift mechanism and an auxiliary anti-theft unit installed with the ability to commute when locking and unlocking the lock, while the auxiliary anti-theft unit is placed inside the castle with the possibility of activating the introduction of a locking temples (RU 2052360 C1, B60R25 / 06, 1996).

This device allows you to lock the control lever of the gearbox to protect the vehicle from misappropriation. However, it is not resistant to cracking using a metal cutting tool.

A mechanical lock is also known, including a key-operated locking gear shifting device mounted on a chassis near the gear lever and equipped with a locking rod with mechanical latches (RU 0006761 U1, B60R25 / 00, 1998).

unauthorized opening.

Of the known devices, the closest to the claimed one is a mechanical interlock for vehicles, containing a bracket attached to the vehicle body, to which a protective cover is attached with protective strips placed in it and a lock with a pin mechanism connected through a stopper with a locking pin equipped with a return spring ( EP 0771279 B1, B60R25 / 00, 1999).

This device is also not reliable enough, since the locking pin can be easily destroyed, for example, sawn, and the fastening elements do not have protection against unauthorized exposure.

The problem solved by the utility model is to create a mechanical lock for vehicles, devoid of the disadvantages of the prototype. The technical result provided by the utility model consists in increasing the reliability of a mechanical lock by increasing its resistance to breaking and non-destructive opening, which makes it possible to increase the efficiency of protection of a vehicle from unauthorized use (misappropriation).

This is achieved by the fact that a mechanical blocker for motor vehicles, comprising a bracket attached to the vehicle body, to which a protective cover is attached with protective strips placed therein and a lock with a pin mechanism connected through a stopper with a locking pin provided with a return spring, is provided with a clutch, rigidly fixed to the thrust of the control lever of the gearbox with the possibility of fixing in it a locking pin, the working part of which is made in the form of a hollow cylinder with longitudinal flat, inside which is placed a cylindrical insert made of carbide material with

the possibility of free rotation around its axis inside the locking pin, and in the part of the locking pin mated to the stopper, a rectangular groove is made, perpendicular to the longitudinal flat, while fixing the protective casing to the bracket is made inseparable. The fastening of the protective casing to the bracket can be carried out by means of screws with stall heads, at least one of which is equipped with a turning washer.

The above technical result is covered by the totality of essential features.

Figure 1 shows a General view of a mechanical lock. Figure 2 shows the protective casing with a locking pin assembly. Fig. 3 shows a lock case with incoming elements. Figure 4 shows the device of the locking pin.

The mechanical lock includes a bracket 1, made mainly of steel (for example, grade 35), to which a protective cover 2 is attached, also made mainly of steel (for example, of the same grade), with a lock 3 with a pin mechanism (not shown in the drawings) shown), the first protective strip 4 and the second protective strip, placed above the working elements of the pin mechanism (not shown in the drawings). Protective strips are made mainly of steel (for example, grade, U7). The pin mechanism located in the housing, mainly steel (for example, grade 35), of the lock 3, is connected through a stopper including a latch 5 and a spring 6, with a locking pin 7. The working part of the locking pin 7 is made in the form of a hollow cylinder, mainly made of steel ( for example, grade 20X, with surface cementation) with a longitudinal flat 8. Inside the hollow cylinder there is a cylindrical insert 9 made of carbide material, for example defeated (grade VK8), with the possibility of free rotation around its axis. In the part of the locking pin 7 associated with

a stopper latch 5, a rectangular groove 10 is made perpendicular to the longitudinal flat 8, so that in this case the cross section of the locking pin 7 is a circle bounded by two mutually perpendicular chords. One end of the locking pin 7 may be made rounded or conical in shape. The locking pin is provided with a return spring 11 from the other end, and an easily removable decorative head 12 can be fixed at this end. The mechanical lock also includes a clutch 13, which is rigidly fixed, for example, by welding, on the rod 14 of the gearbox control lever, with the possibility of fixing the locking pin 7. It is possible to secure the clutch 13 directly to the control lever of the gearbox. The fastening of the protective casing 2 to the bracket 1 is made non-separable, for example, by means of screws, mainly heat-strengthened, with stall heads, at least one of which is equipped with a turning washer (not shown in the drawings). The execution of the screw heads detachable can be carried out, for example, by reducing their size compared to standardized ones. The bracket 1 is attached to the vehicle body mainly by means of a fastening resistant to unauthorized separation, for example, fastening screws with washers and nuts intended for mounting and dismounting with the corresponding specific mounting tool (not shown in the drawings). The mechanical lock is also provided with a key 15, mating with the pin mechanism of the lock 3.

The mechanical lock operates as follows. The owner of the vehicle puts the gearshift control lever in the set position, mainly in the reverse position. Then inserts the locking pin 7 into the hole of the protective casing 2 until it

complete fixation, while the latch 5 of the stopper enters the groove 10, the locking pin 7 through the through hole in the lock housing 3 enters the thrust tunnel 14 and is fixed in the coupling 13. After that, the movement of the thrust 14 in the tunnel becomes impossible, which makes it almost impossible to control motor means. The lock is released using the key 15. Before starting the movement of the vehicle, the locking pin 7 is removed from the lock 3.

The design of the mechanical lock makes it less vulnerable to cracking. The fixing unit based on the clutch 13 is located outside the space of the cab of the vehicle. The locking pin 7, having a shaped profile in its working part associated with the stopper, is reliably fixed in a certain position relative to the lock case 3. This makes it almost impossible to squeeze the stopper with the help of cylindrical picks, while the locking pin 7 is extremely resistant to destruction by its sawing or impact fracture due to the presence of a turning insert 9 of carbide material. Resistance to the destructive effect on the fasteners of the lock 3 to the bracket 1 is ensured by the installation of non-separable (one-time operation). The resistance of the mechanical lock to opening by depressing the stopper or by drilling the pin mechanism of the lock 3 through the holes drilled in the protective cover 2 and the lock case 3 is ensured by the presence of the first protective strip 4 and the second protective strip placed above the working elements of the pin mechanism.

The mechanical lock, made in accordance with the utility model, has high reliability, having increased resistance to breaking and unauthorized opening, and is convenient to operate.
