Description

The utility model relates to the field of road transport, in particular to equipment designed to prevent theft or unauthorized use of a vehicle.

It is known to use various blocking means (blockers) to protect the car from theft. The locks are mounted on the steering wheel, on the steering wheel shaft, on the brake pedal, on the gear lever, or on other movable structural elements of the vehicle.

So in the description of the patent of the Russian Federation for utility model No. 24978, IPC: B60R25 / 02, publ. 09/10/2002, an anti-theft device for a vehicle is disclosed comprising a locking pin, in the end of which a cylinder locking mechanism is arranged associated with a locking device configured to reciprocate in the working part of the locking pin, and a clutch rigidly mounted on the steering shaft . This steering wheel pin lock, like other traditional steering shaft pin locks, does not always counteract the rotation of the shaft, requires careful and careful installation and, most importantly, requires tedious and complex driver movements to lock the steering wheel.

The prior art also presents universal devices that are configured to block various vehicle controls with pinless locking means.

From the patent of the Russian Federation for utility model RU125144, IPC: B60R25 / 00, publ. 02/27/2013, a mechanical anti-theft device is known that a vehicle can be installed to block various controls. Said device comprises a lock with a secrecy mechanism, consisting of a fixed cylindrical body and a movable block located inside the fixed body. The movable unit is connected to the locking bolt by means of a flexible rod located in the protective casing. Moreover, the lock case is rigidly connected to the end part of the protective casing, and on the opposite end of the protective casing there is a locking bolt connected to the corresponding end of the flexible rod. The end of the flexible rod opposite the bolt is rigidly connected to the movable block of the lock secrecy mechanism, and inside the lock body, in the area of the flexible rod to the movable lock block, the return spring is located.

The device protected by patent RU125144 does not allow to block the rotation of the steering shaft, because it does not contain a protective structure for fixing the bolt with respect to the steering shaft.

A similar device, claiming to be universal, locking the movable elements of the vehicle, such as the steering shaft, gear lever, etc., is disclosed in utility patent RU134126, IPC: B60R25 / 00, publ. 11/10/2013. The specified mechanical anti-theft device contains a housing fixed in the vehicle body with a lock in place with a secret mechanism, a movable shaft with a key channel, which is equipped with a disk, a profiled pipe connected to the body, in which a flexible flexible rod is installed, one free end of which is equipped with bolt and made with the possibility of entering into the locking connection with the movable element of the vehicle, which must be fixed, and the other with the sleeve, is connected with a disk with the formation of a rocker mechanism. Moreover, an electric switch is installed in the housing, connected to the vehicle body and a relay for closing the circuit when the link mechanism is corresponding to the locking bolt connection, and the circuit is broken when the link mechanism is corresponding to the absence of the locking bolt connection. Relay connected to vehicle starter and ignition switch.

The disadvantages of this solution, reducing its reliability, include the use of an electric relay as part of an anti-theft tool.

In the prior art, specialized anti-theft means are also provided, which are designed specifically to block the possibility of rotation of the steering shaft. From the patent of the Russian Federation for utility model No. 31540, IPC: B60R25 / 02, publ. 08/20/2003, an anti-theft device for locking a vehicle’s steering shaft is known, including a locking device cooperating with a locking rod mounted to move in a direction perpendicular to the axis of the steering shaft, a sleeve with a hole for the locking rod fixed to the steering shaft. The locking device is made in the form of a lock insert installed with the possibility of sliding in the sleeve fixed in the vehicle body and made with the possibility, when the key acts on the locking mechanism, to lock in the position retracted into the sleeve, return to its original position and fix it, the end of the lock insert connected to the blocking rod by means of a shaft placed in a tube attached to the vehicle body, while in the position of the lock insert removed in the sleeve of the lock blocking rod placed in the hole coupling, and in the rest position is located outside this opening.

However, the sliding recessed locking device with a spring-loaded translational displacement transmission mechanism is not sufficiently reliable due to the risk of spring breakage.

From the patent of the Russian Federation for utility model No. 139460, IPC: B60R25 / 06, publ. 04/20/2014, it is known a device for preventing unauthorized use of a vehicle, which contains a lock insert with a privacy mechanism and a key connected via a drive to a locking device containing a locking bolt. In this case, the drive is made in the form of a flexible shaft fixed at one end in the lock insert and transmitting torque from the key to the gear fixed on the other end of the shaft. The disadvantage of this device is the location of the rack gear at the far end of the flexible shaft, which requires considerable effort to communicate the translational movement of the bolt. Efforts go to overcome the forces of friction and bending the shaft to twist under the action of torque. For example, in the description of the patent of the Russian Federation No. 139460 it is indicated that the locking mechanism is connected hydraulically to the locking mechanism of the control shaft lever. The use of hydraulic communication is aimed at eliminating the following disadvantages:

increased magnitude of the force required to rotate the key in the locking mechanism, due to high friction caused by the interaction of flexible traction with conjugated elements;

low reliability of devices due to wear of flexible traction;

the possibility of breaking the kinematic connection between the castle part and the locking mechanism.

Among foreign analogues, it is advisable to note the technical solution disclosed in US patent No. 2553790, IPC: B60R25 / 02, publ. 05/22/1951, which is a device to prevent unauthorized use of the car, containing means for blocking the rotation of the steering shaft, made in the form of a non-rotating clutch located on the steering shaft, and a locking mechanism interacting by means of a bolt with grooves of the clutch, and the translational movement of the bolt is provided by flexible a shaft interacting with the rotary mechanism of the lock displayed on the front panel of the car.

A disadvantage of the known solution is the implementation of the coupling with the possibility of sliding movement along the steering shaft, which reduces the reliability of the device. Also, the disadvantages of this solution, reducing its reliability, include the use of an electrical circuit for controlling an anti-theft tool.

From German patent No. 4446613, IPC: B60R25 / 02, published April 29, 2004, an anti-theft device is known in which the rotation of the ignition key interacts with a locking means on the steering shaft through a flexible rod. The steering lock is controlled from the ignition using the ignition key. The connection between the ignition switch and the steering wheel lock is made in the form of a flexible drive, for example in the form of a Bowden cable. In the retracted position of the Bowden cable, the end of the ignition switch is secured by a safety lock to prevent accidental operation of the lock, while the locking bolt is spring-loaded in the locked position. The whole system can be controlled by solenoid drives, and the ignition switch can be connected to a coded security system. A disadvantage of the known solution is the low reliability of the device.

As a prototype of the claimed utility model, it is advisable to select the “Anti-theft device for locking the steering shaft of the vehicle” mentioned above, disclosed in the description of the patent of the Russian Federation for utility model No. 31540, B60R25 / 02, published on 08/20/2003.

The shaftless locks of the steering shaft currently on the market are equipped with large and unaesthetic locking cylinders that spoil the interior of the car and are not convenient to control, as they are located in places that are difficult for the user to access and often require adjustment of the steering column to lock. The proposed steering shaft lock is devoid of the disadvantages identified in the known technical solutions.

The development of a utility model is aimed at solving the problem of expanding the arsenal of reliable mechanical means to prevent unauthorized use of the car by blocking the rotation of the steering shaft.

The technical result is a reduction in effort to block the rotation of the steering shaft while increasing the reliability of the anti-theft device.

To solve this problem, a device for preventing unauthorized use of the car by blocking the rotation of the steering shaft, comprising a clutch with slots made with the possibility of fixed placement on the steering shaft of the car, and means for blocking the rotation of the steering shaft located in the housing, including a key cylinder, interacting with a flexible rod connected at the other end to the bolt with the possibility of moving the bolt into the groove of the coupling, characterized in that on the core of the key cylinder a part is installed, which is connected via a crank to a connecting rod connected to a flexible rod with the possibility of reciprocating movement of the bolt during revolution of the core of the key cylinder.

The housing for accommodating the means for blocking the rotation of the steering shaft is made in the form of a curved pipe connected at an angle to the nozzle, and the bolt with a flexible rod and connecting rod are placed in a part of the housing made in the form of a curved pipe, and the key cylinder and part with a crank are placed in the part case made in the form of a pipe.

The casing is preferably made of steel, while the parts of the casing are connected to each other by welding and are equipped with fastened fastening elements in the form of brackets of the corresponding form for stationary fixing of the claimed device to the car body elements.

Note that the crank part is preferably made in the form of a disk with a cylindrical protrusion on a flat surface. The protrusion is preferably made in the form of a pin, the axis of which is offset relative to the axis of the disk with a given eccentricity, so that a doubled amount of eccentricity determines the maximum stroke of the crossbar.

However, other configurations of crank execution in this device are also possible. Moreover, the disk shape of the crank is preferred, since the massive disk is a flywheel, which facilitates the transfer of force from the lock core to the crossbar of the claimed device.

In accordance with the proposed technical solution, the use of a crank mechanism in conjunction with the core of the cylinder lock, made with a longitudinal key groove, allows the key to be converted into reciprocating movement of the bolt to lock and unlock the steering shaft.

To lock the protective structure is a coupling designed to be placed on the steering shaft of the car. For the operation of placing the coupling on the shaft, it is made of two coupling halves made with the possibility of a rigid connection between each other and with the steering shaft of the car.

The grooves on the coupling can be made in the form of slots of various shapes or in the form of blind holes, with the possibility of interaction with the bolt in the longitudinal direction either in the transverse direction or at an angle.

The utility model is illustrated in figures 1-4.

The figure 1 shows a device for preventing unauthorized use of the car in the closed position, when the bolt interacts with the clutch groove in the transverse direction relative to the axis of the steering shaft.

Figure 2 shows the device shown in figure 1, in the "open" position.

Figure 3 shows a device for preventing unauthorized use of the car in the closed position, when the bolt interacts with the clutch groove in the longitudinal direction with respect to the axis of the steering shaft.

FIG. 4 shows the device of FIG. 3, in the "open" position.

In figures 1-4 adopted the following position designations:

1 - a housing in the form of a curved pipe, which serves to accommodate means for blocking the rotation of the steering shaft;

2 - pipe, which serves to accommodate the key cylinder and parts with a crank;

3 - lock cylinder;

4 - flexible traction;

5 - a rod;

6 - crossbar;

7 - coupling;

8 - a steering shaft;

9 - body element (steering column bracket);

10 - mounting element on the device.

As shown in FIG. 1, the device for preventing unauthorized use of the car contains a clutch 7 with grooves, which is stationary on the steering shaft 8 of the car. In this case, the bolt 6 is a means of blocking the rotation of the steering shaft 8 when it enters one of the grooves of the clutch 7. When the car steering wheel is turned, the clutch 7 rotates together with the steering shaft 8, so the grooves are displaced, but in any situation, you can choose a position so that either of the grooves is located opposite the crossbar 6.

The housing of the device consists of two parts, namely, from a bent pipe 1 and pipe 2, connected in the case shown in figure 1, at an angle of approximately 90 ^about . However, in the general case, the angle of connection of the bent pipe and the nozzle in the device body may differ from that shown in the drawing, since it is selected depending on the configuration of the interior space of the car interior taking into account the possibility of placing the key groove of the key cylinder on the front panel in the immediate vicinity of the driver in a convenient place .

The locking means includes a locking cylinder 3 provided with a core made with a longitudinal key groove for accommodating the key. A disk-shaped part is mounted on the core of the locking cylinder from the end side opposite to the key groove, which is connected via a crank to a connecting rod 5 connected to a flexible rod 4, the end of which is connected to the crossbar 6 with the possibility of reciprocating movement of the crossbar 6 when revolution of the core of the lock cylinder 3.

The proposed utility model is designed to protect the car from theft, by fixing the steering shaft 8 from rotation by the pinless method with unauthorized access to the car. Used in the design of the claimed device, the means for blocking the steering shaft is equipped with a locking cylinder 3 having small dimensions.

The device operates as follows.

The claimed device to prevent unauthorized use of the car is installed in the car interior at regular places, with the locking cylinder 3 in the immediate vicinity of the driver on the front panel in a convenient place, and is mechanically controlled by the key due to the kinematic connection of its structural elements.

To prevent unauthorized use of the car, the user puts the device in the "closed" position, for this he places the key in the key groove of the core of the key cylinder 3 and makes half a key turn. In this case, the part mounted on the core of the lock cylinder 3 makes a half turn and moves the crank to the opposite end of the diameter of the lock cylinder 3. In this case, the connecting rod 5, pivotally connected to the cylindrical protrusion (crank) on the surface of the said part, communicates the translational movement of the flexible rod 4, opposite the end of which pushes the bolt 6 from the bent pipe 1 in the direction of the corresponding position of the groove of the clutch 7, mounted on the steering shaft 8. Thus, in the locked position the locking rig s 6 prevents rotation of the steering shaft 8 and prevents vehicle theft. The lockable design is a clutch 7 mounted on the steering shaft 8, allowing to lock the steering shaft 8 in any position of the steering column adjustment and with almost any direction of the wheels.

In figures 1 and 3 shows a device to prevent unauthorized use of the car in the closed position, when the bolt interacts with the clutch groove, respectively, in the transverse and longitudinal directions relative to the axis of the steering shaft.

A full turn of the key allows you to put the device in the "open" position.

In figures 2 and 4 shows a device to prevent unauthorized use of the car in the "open" position, in the absence of interaction of the bolt with the groove of the clutch. In this position, the steering shaft rotates freely, and unimpeded control of the car is possible.

For the convenience of placing the claimed device in the passenger compartment of the car, a part of the hollow steel body is made in the form of a curved pipe 1 of circular cross section, repeats the shape of the inner space of the front panel of the car. The body of the device to prevent unauthorized use of the car is mounted inside the front panel using a detachable fastener. The coupling 7, which is fixedly mounted on the steering shaft 8, is also mounted using stall fasteners. Installing the claimed device inside the panel of the passenger compartment significantly complicates attempts to mechanically affect the housing and actuators of the anti-theft device. The use of the claimed device is characterized by a minimal change in the appearance of the cabin, since a miniature key cylinder is used.
