Description

 The invention relates to the automotive industry, in particular to anti-theft means.

 The closest solution to the invention in technical essence is the lock for the lever of the hand brake of the car [1] This lock has number rings with grooves, which include the fingers attached to the pusher acting on the release button of the hand brake. When turning the ring acts on the first finger and holds the pusher in a position insufficient to press the button, but in which the rotation of the rings is impossible.

 However, this lock has a rather complicated structure and, in addition, even with its use a car theft is possible.

 The described lock is designed to lock the steering column while the car is parked and can serve as an anti-theft tool. When using a lock, for example with 5 number rings, it is possible to obtain 75.287.520 combinations of codes.

 The aim of the invention is to simplify the design while increasing the reliability of the lock by eliminating the possibility of determining the code "by ear" and the inclusion of the lock.

 In FIG. 1 shows a section through the castle; figure 2 section aa in figure 1; figure 3 section BB in figure 1; figure 4 section BB in figure 1.

 The lock for the steering column of the car contains a housing 1, made in the form of a detachable collar with a cylindrical shank and a sleeve 2. Inside the shank of the housing is a spring-loaded rod 3. The sleeve 2 is mounted on the steering column and has slots for the passage of the rod 3. Numbering rings 4 are installed in the shank of the housing 4 , supported by spring-loaded plugs 5. In the body of the shank, under each number ring, two through holes are made at an angle, in which spring-loaded balls 6 are mounted, fixing the number ring when it rotates to zhdy cipher. The rings have an internal groove 7 and with a certain cipher for opening the lock, the grooves 7 smoothly rise on the ledge 8, made in the body of the ring, and press on the balls 9, which lower the cylindrical plugs 5 on the surface of the rod 3. Balls 9 and plugs 5 are located in the holes made under each ring in the body of the stem and the shank of the housing, and when closing the lock, the spring-loaded plugs 5 enter the shank of the housing 1 and the stem 3, thereby locking the lock. At the end of the rod there is a stop 10, on which the spring 11 is supported. Under its influence, the rod 3 leaves the sleeve 2 and releases the steering column. In addition, the castle has another degree of secrecy. After dialing the cipher to open the lock, it is necessary to press the key 12 on the spring-loaded locking pin 13 located in the stem hole. On the housing there is a hole 14 for the key. Radial grooves 15 are made on the inner surface of the ring, which fix each pin when turning the ring opposite the mark 16, painted, for example, in white.

 The castle operates as follows.

 When the car is parked, a code is dialed, stem 3 is pressed to lock the steering column. The pin 13 is automatically latched by the action of the spring. The code gets lost by turning the rings.

 Before the movement, a code is dialed, pushed with a key 12 on the pin 13, the rod unlocks the sleeve 2 under the action of the spring 11.

 To prevent accidental operation of the lock during movement, the code should be knocked down by turning the rings.

 In addition, the possibility of theft can be further excluded by unfolding the wheels of the car in the parking lot.

 Each number ring has 20 alphanumeric values and when it is rotated, no significant opening effort is created. In this lock, small efforts are created on the rings and a click occurs on each cipher, as a result of which it is impossible to "hear" the current lock opening code.

Claims (1)

 A car lock, comprising a housing with a sleeve for covering a vehicle element, and a locking device, including number rings coaxially mounted rotatably with annular and longitudinal grooves on the inner surface, designed to interact with radially protruding latches, characterized in that the housing is made in the form of a detachable collar with a cylindrical shank on which the number rings and the rod inserted into the lock are located, while in the shank under each number ring m there are two non-through holes designed to accommodate spring-loaded balls inserted into the lock, and coaxial holes designed to accommodate the said clips made in the form of spring-loaded plugs in the rod and shank, an inner ledge is made on each ring, and the lock is equipped with a spring-loaded pin, located in an additional bore made in the shank and designed to interact with the lock key.
