Figure 1 shows a perspective view anti-theft device in accordance with the present invention.
Anti-theft device comprises a yoke 3, fixed to the body 5 anti-theft device. In particular, the yoke 3 is fixed to the housing 5 of the device using the first poluchat 3a. First poluchat 3a has the shape of a semicylinder.
The clamp 3 also contains a second poluchat 3b, also having the shape of a semicylinder.
First poluchat 3a and the second poluchat 3b restrict the internal space, which may be the steering column (not shown).
The second poluchat 3b connected by their ends to the first Polygonatum 3a.
One of its ends a second poluchat 3b is mounted on the first polygonale 3a via a hinge. The specified hinge contains the axis fixedly connected with the first Polygonatum 3a and passing vertically.
The other end of the second poluchat 3b is mounted on the first polygonale 3a by means of fastening.
Thus, the clamp 3 forms an internal space in which can rotate the steering column. To block this rotation, for example, to prevent theft of the vehicle, the first poluchat 3a includes a guiding slot that is open in the inner space of the yoke 3 and which moves the slide valve 7.
The valve 7 has the General shape of the bar, essentially square cross section.
The end of the valve 7 is of the form, the return hole is made is in the steering column, so that when the valve is in the interior, it passes into the hole of the column blocks and, thus, any rotational movement of this column.
First poluchat 3a is a sensitive part of the anti-theft device 1 from the point of view of protection. Indeed, the first poluchat 3a includes a guiding slot of the valve 7, which should be protected from any hacking attempts. So this first poluchat 3a made of a durable material. This material may be, for example, an alloy of zinc and aluminum, such as "zamak" (registered trademark).
Case 5 anti-theft device also can be made of material "zamak" (registered trademark). However, to limit the total weight of the anti-theft device 1, the housing 5 anti-theft device can be made of lighter material, such as magnesium alloy or heavy-duty plastic material filled with glass fibers.
Figure 2 in partial section showing an anti-theft device shown in figure 1.
As shown in this figure, in block 5 of the anti-theft device is lock 9 containing the rotor and the stator, in this case, when the user turns the ignition key, this key rotates the rotor of the lock.
The rotor causes the rotation of the Cam 11. Progressive DV the position of the Cam 11 in block 5 of the anti-theft device is provided by castle 9.
During the rotation of the Cam 11 progressively moves the slider 13.
When the user turns the ignition key to start the vehicle engine, the rotor lock 9 rotates the Cam 11, which moves the slider 13. When the slider 13 moves the translational movement of the valve 7 in the position in which it no longer blocks the rotation of the steering column. The valve is held in this position throughout the operation of the vehicle.
If the user turns the key and remove it from the lock 9, the spring pushes the valve 7, which blocks the rotation of the steering column.
In block 5 of the anti-theft device enters the pin 15 connected to the lock 9 through the Cam 11. Pin 15 allows you to hold funds 17 lock in the off position. Pin 15 is the element that is separate from the lock 9. In the embodiment, the pin 15 may be part of the castle 9.
These funds 17 locks are designed to lock the translational motion of the valve 7, when the lock 9 is disconnected from the housing 5 anti-theft device or when the housing 5 of the device is extracted by force.
When funds 17 locks are in working position, i.e. in the position in which they block the forward motion of the specified valve, they are held in this position environments is Tami 19 hold. These funds 19 retention are designed to prevent any change of position means 17 locks from their working position.
Figure 5 shows in detail the means 17 of the lock and means 19 hold.
Means 17 contain lock plate 21 and the first spring means 23.
The plate 21 limits the window 24, which may enter the valve 7. Thus, when the plate 21 is installed in the anti-theft device 1, it may, due to the presence of the window 24 to be transversely relative to the axis of translational movement of the valve 7.
Box 24 has an inner width greater than the height of the valve 7, so that the window can move relative to the valve 7, when the plate 21 is not more in the off position. During the movement of the plate 21 from the outside position to the working position, it comes into the groove 25 (also shown in figure 4), made in the valve 7. The thickness of the plate 21 is determined so that she could go into this groove 25.
The plate 21 also contains the upper part. As shown in figure 2, this upper part is made in the form of a rod 27, protruding vertically from the window 24 to pin 15.
The plate 21 also contains the lower part. This lower part is made in the form of two legs 29 (shown in particular in figure 5), which run vertically from the window 24 to the NRA is a t the bottom of poluchat 3a. These legs 29 are made so as to guide the first spring means 23.
The plate 21 is made of a material that can withstand the strong pressure from the side of the valve 7, for example, from a material such as steel or corrugated sheet.
The first spring means 23 is arranged to impact the plate 21 in the direction of the working position, i.e. in the direction in which the means 17 of the locking block forward movement of the valve 7. Due to this first spring means 23, the means 17 of the lock can be moved vertically in the space bounded by Polygonatum 3a, the slider 13, the Cam 11, the housing 5 anti-theft device (shown in figure 2).
The first spring means 23 is made in this case in the form of a cylindrical coil spring, one end of which is in contact with the plate 21 and the other end comes in contact with Polygonatum 3a.
In the embodiment, the first spring means 23 can be made in the form of an elastic plate fixedly connected to the plate 21.
Figure 3 shows a perspective view of the means 19 hold.
These funds 19 retention contain the bracket 31 and the second spring means 33.
Figure 4 in more detail shows a portion of the bracket 31.
The bracket 31 comprises a base 35, which runs two branches 37 (figure visible only davetv). Each branch contains 37 of the inner protruding portion 39. Both the inner protruding portion 39 of the two branches 37 facing each other and directed to the inside of the bracket 31.
In this case, the bracket 31 is locked in position by a plate 21. In particular, the plate 21 holds the bracket 31 by blocking the inner protruding portion 39 by means of the respective legs 29.
Second spring means 33 is arranged to impact on the bracket 31 in the direction in which the bracket 31 of the holding means 17 locking in the working position. Thanks to this second spring means 33, the bracket 31 can be moved by sliding inside poluchat 3a.
In this case, the second spring means 33 is made in the form of a cylindrical coil spring, one end of which is in contact with the base 35 of the bracket 31 and the other end comes in contact with Polygonatum 3a. In this case, the second spring means 33 has a direction of movement transverse to the direction of movement of the first spring means 23.
In the embodiment, the second spring means 33 can be made in the form of an elastic plate fixedly connected with the base 35 of the bracket 31.
What follows is a more detailed description of the movement of various elements of the anti-theft device 1, when the hijacker disconnects lock 9 from the rest of the device 1.
figure 2 shows the means 17 lock anti-theft device 1 in the off position.
In this off position, the plate 21 is locked in its upper part with a pin 15 in its lower part, the first spring means 23, which compresses the plate 21.
The plate 21 also holds the bracket 31 in the position in which it compresses the second spring means 33.
In case of disconnection of the lock 9 from the anti-theft device 1 or in the case of power extraction block 5 anti-theft device the Cam 11 is no longer held to the linear movement of the lock 9. The Cam 11 is moved, pulling the pin 15. The pin 15 releases the plate 21, which under the action of the first spring means 23 is moved vertically. When this plate 21 comes into the groove 25 of the valve 7.
During its vertical movement of the plate 21 releases the bracket 31, which is under the action of the second spring means 33 is moved so that the inner protruding portion 39 is passed under the legs 29, as shown in figure 5. This inner protruding portion 39 hold the plate 21 in position. Thus, even if the hijacker has access to the RAM 13, the valve remains locked in the steering column, by means of 17 locks and tools 19 hold.
It should be noted that the contact surface of the inner protrusions 39 are made so that TREN is e between these surfaces and the respective legs 29 was minimal. Therefore, limit the transfer of shear stresses from plate 21 on the bracket 31 when this plate 21 is moved relative to the bracket 31, which is when the locks are in working position and when the hijacker applies a transverse force to the valve 7, trying to unlock the steering column.
In addition, the inner projecting parts 39 are placed under the legs 29 so that the clearance between the locking means and the valve 7 is limited. Due to this fatigue limit stress on the means 17 of the lock in the case of repeated impact load on the valve 7.
It should also be noted that even in the case where the hijacker has access to the top of the plate 21 (for example, by power extraction block 5 anti-theft device), it will not be able to deactivate the means 19 hold. Indeed, the means 19 retention act irreversibly so that, when the inner projecting parts 39 are under the legs 29, the bracket 31 is impossible to return to its original position.
Thus, the invention allows to obtain a reliable anti-theft device even in case of disconnection of some parts of the anti-theft device 1.
In the embodiment, the invention can provide for early spring among the society in the form of a cylindrical helical springs, the first end which comes in contact with the plate, and the second end is in contact with the means of restraint, therefore, when the plate is moved vertically, the first spring means to move the means of keeping under the plate. In this particular configuration, the second spring means is not needed.
In the embodiment of the invention, shown in Fig.6, the reliability of the anti-theft device 1 is improved even more.
In this embodiment, the portion of the plate 21, the bounding box 24 contains on its two legs, two cutout 41. These cutouts 41 directed toward the center of the plate 21 and form a zone of rupture of the plate 21. Thus, when the hijacker operates the load on the bolt in the transverse direction, the joint efforts of the valve 7 and poluchat 3a on the plate 21 lead to break this record 21 level two notches 41. The lower part of the plate 21 remains in its working position under the action of means 19 hold. Therefore, the plate 21 continues to hold the valve 7 in the position in which it blocks the rotation of the steering column.
The notches 41 are valid also in the case when the thief tries to force eject plate 21 by pulling the upper rod 27 of this plate 21 (shown in Fig.2) in the power extraction block 5 anti-theft device. In this situation, the pressure ponsi is and the rod 27 causes the twisting of the plate 21. This twisting of the leads, ultimately, to break the plate 21 at the level of the two cutouts 41.
Thus, the notches 41 performs the function of fuses in case of too large forces acting on the plate 21.

SUBSTANCE: security alarms reveal intrusion of criminal into vehicle and form alarms messages by which high frequency signals are modulated. The latter are transmitted by retransmission-radio direction finding network and by standard cellular mobile communication network to dispatcher center. Test signals confirming communication with of vehicle with dispatcher center are received on high-jacked vehicle by standard cellular network. Alarm messages are selected and processed in dispatcher center, identification signs of high-jacked vehicle and its location are determined and initial and current external target designations are transmitted to security hazard express vehicle and, if necessary, movement of high-jacked vehicle is blocked. When messages are transmitted by retransmission-radio direction finding network, coincidence of messages transmitted and received by radio are checked on board the high-jacked vehicle. In case of no coincidence, signal of interruption of reception by retransmission-radio direction finding network is formed. When test signals are received by standard cellular network on high-jacked vehicle, mean signal/noise ratio for preset internal is determined and compared with preset threshold, and if they drop to threshold level with simultaneous interruption of reception by retransmission-radio direction finding network, high-jacked vehicle interlock units are acted upon to stop the vehicle. Object terminal generates alarm signals which are taken by security hazard express vehicle. Bearings and external target designations are used to control movement of security hazard express vehicle at intercepting high-jacked vehicle.
EFFECT: improved efficiency of interception even if high-jacked use vehicles.
