The wedge unit is moved apart and pressed against a wall of the barrel such that the barrel is blocked, where the wedge unit is further pressed against the wall, when pressure is applied at the locking unit from outside. An actuator operated by an electronic circuit moves the actuating unit away from the wedge unit such that the wedge unit moves back into a position at which the locking unit is removable from the barrel. Independent claims are also included for the following: (1) an operating unit for a locking unit (2) a method for locking a locking unit in a barrel of a weapon.

Description

The The invention relates to a locking device and method the barrel and / or the cartridge chamber of a weapon. Such devices or Security devices are usually in the arms of a Armed weapon and prevent the weapon to be fired can.

From the DE 198 41 107 A1 (ProSafeArms), for example, a backup is known in which the cartridge chamber or the cartridge chamber is blocked with turret. For this purpose, a safety sleeve is first introduced by the normal charging in the chamber. Furthermore, a guide tube is inserted with a locking pin from the mouth in the direction of the cartridge chamber. To lock the cartridge chamber, the locking pin is locked in the safety sleeve. At the end of the guide tube a lock is further provided that, for example, a combination lock or a lock or padlock can be and serves to secure the locking pin and the safety sleeve from the outside against unauthorized removal. However, such a fuse has the disadvantage that the lock can be easily cracked from the outside and therefore does not provide reliable protection.

From the US Pat. No. 5,950,344 (Omega) is also known a fuse element that is inserted into a gun barrel and can be stretched in the run that it blocks. The securing element in this case has a compression shaft which has a connecting piece at one end. The compression shaft passes through a bore of an expansion element (preferably rubber) and terminates in a threaded portion which is connected to an internally threaded tube. Is rotated on the neck and thereby on the compression shaft, the threaded portion is screwed into the tube, thereby compressing and expanding the expansion element. However, such a securing element, in which the expansion element consists for example of a rubber material, has the disadvantage that. It can be easily removed and thus provides no reliable protection Furthermore, the fuse element is cumbersome in the handle, characterized in that several handles are necessary, the fuse element in the run to place and remove from this again.

From the DE 199 63 326 A1 A similar locking or blocking device for revolvers and self-loading handguns is known. The blocking or blocking device consists of two security elements. The first securing element has an external thread on one side, on which a rubber segment sits, but that does not completely cover the thread. The first fuse element is loaded into the turret by a normal cartridge loading operation. From the mouth side, a second securing element is inserted into the barrel that has a matching bore with internal thread for receiving the external thread. About a special key, the two securing elements are then screwed together so that the rubber element is compressed and thereby radially expands, so that it blocks the barrel. As mentioned above, such security devices have the disadvantage that they can be easily removed and are also cumbersome to handle.

Furthermore, from the DE 38 36 361 A1 a device for protecting Kipplaufwaffen known. In this case, a rod, provided at its front end with a diameter-equal hemispherical conclusion, which makes insertion into the gun barrel possible and can be provided later with a lock, z. B. a padlock. The rear end of the rod, however, is provided with a barrier in the form of a collar-like conclusion, wherein the collar-like conclusion is greater than the diameter of the gun barrel. The rod is inserted with its front end in a tilting gun barrel until the collar-like conclusion abuts the barrel, while the other end is locked with a lock, so that the rod can not be pulled out of the barrel. Such a device has the disadvantage that the lock easily broken or the gun barrel can be sawed off easily. The device therefore does not provide reliable protection against unauthorized users. In addition, it can only be used with rifle-throwing weapons.

From the WO 2004/008058 A1 (SimonsVoss) is further a firearm backup known that can be introduced into a gun barrel. In this case, a clamping device is operated with expanding jaws from the outside by twisting an armor, which is connected to a Spreizgewinde. Furthermore, a deactivation element with an additional actuator is provided. Unlocking the firearm fuse is only possible if the deactivation element releases the Spreizgewinde so that it can be rotated. In one embodiment, the armor can also be connected to a coupling device that rotates the armor so that the firearm fuse z. B. is unlocked when the actuator releases the Spreizgewinde on the deactivation element.

task It is an object of the invention to provide an apparatus and a method reliable with a weapon can be locked and also easy and fast to handle is.

These The object is achieved by a blocking element according to claim 1 or 2, a Operating unit according to claim 29 and a method according to claim 3 solved. The blocking element has the advantage that it is the barrel of a weapon reliable can lock in both directions, d. H. from the side of the estuary and from the side of the cartridge chamber by the barrel through Wedge element is blocked. Furthermore, the blocking element can be very simply and quickly mounted in a gun barrel and off again This can be removed by an actuator that uses an electronics lock element actuated.

Further preferred embodiments are in the subclaims Are defined.

How out 1 and 2 it can be seen, so is in the barrel 6 a weapon from the muzzle side a blocking element 2 inserted according to an embodiment of the invention and locked there. The loading and firing of the weapon is thereby prevented. To remove the blocking element 2 and to re-start the weapon had an unauthorized third party the entire run 6 replace the weapon.

In one embodiment of the invention, the self-locking weapon safeguard consists of the blocking element 2 and preferably a separate control unit 4 , The operating unit 4 preferably remains outside of the barrel 6 ,

The operating unit 4 can be used to transmit and / or receive data with the blocking element 2 be coupled. The data transfer between blocking element 2 and control unit 4 can be wired or wireless. The operating unit 4 can mechanically and / or electrically with the blocking element 2 be coupled.

A wireless coupling can be done over the air, for example by means of inductive coupling, in the longitudinal, long and / or medium wave range done, z. In the range of 3 kHz to 30 MHz.

The wireless coupling can furthermore also take place via an optical device or via an electromagnetic coupling in the microwave and UHF frequency range, for example from 400 MHz to 5 GHz. In a wired transmission, for example, the transmission via a 1-wire bus. The coupling between control unit 4 and blocking element 2 , may also be a combination of the aforementioned coupling options.

Between the control unit 4 and the blocking element 2 data and / or energy can be transmitted.

The Electronic 9 is preferably within the barrier element 2 arranged, but can also be in the control unit 4 be provided. The Electronic 9 performs an authorization check and / or enables the actor. The actuator is preferably in the blocking element 2 However, it can also be located in the control unit 4 be provided. The operating unit 4 is used for data input (eg Entering a PIN code and / or biometric data), the data from the control unit 4 to the electronics 9 be transferred for authorization check.

The Electronic 9 can be self-sufficient z. B. via a battery 10 and / or not self-sufficient or partially self-sufficient by energy through the control unit 4 for example, via a wire or a line is supplied. In an alternative, energy can also be inductively supplied.

The operating unit 4 can via a coupling device 12 with the blocking element 2 be connected to the blocking element 2 in the arms race 6 to unlock and / or re-lock.

The blocking element 2 preferably complete in the gun barrel 6 and / or the cartridge chamber are introduced, such. Tie 1 and 2 shown. Furthermore, it is located in the blocking element 2 a mechanism for barrel locking, which will be explained in detail below, and optionally a preferably electromechanical actuators, which releases and / or blocks and optionally a miniature electronics 9 which controls the actuators.

The blocking element 2 initially has a sleeve 14 in which an actuator and an actuator 16 and a spreading element are arranged. The expansion element can, as shown in the figures, as a wedge element 18 be executed while at least one or two wedge plates or z. B. according to the 1 . 2 and 4 to 9 for example, three wedge plates 18 consist.

In principle, there are arms runs 6 with or without existing cartridge storage. Gun barrels without cartridge bearings have a substantially cylindrical construction with a continuous diameter, as in 3b shown. Furthermore, there are weapon runs where the arms race 6 has a transition to the cartridge chamber (gun barrel with chamber), ie a transition from a smaller diameter of the barrel to a larger diameter of the barrel in the region of the cartridge chamber (see. 3a ).

In one embodiment of the invention, the wedge element 18 be designed so that it at least partially in a chamber transition of a gun barrel 6 can be introduced. In this embodiment, while the wedge element 18 to block the run 6 mounted in the transition so that it is at least partially or completely applied or pressed in the region of the transition in order not to be pulled out in the direction of the mouth of the barrel can, for example, greatly simplified in 3a is shown. The wedge element 18 forms with the transition a positive connection in the direction of the mouth of the barrel. The blocking element 2 can not be pulled out of the barrel to the mouth side. Further, by pressing the wedge member against at least a portion of the cylindrical portion of the barrel and / or the cartridge chamber, a frictional engagement is also created so that the blocking member can not be removed in the direction of the cartridge chamber.

The embodiment according to 3a shows a locking mechanism according to the invention, which represents the principle of self-locking effect. In this case, the actuating element and the roller element guide 20 trained (see eg. 4 ) that when pressure from the muzzle side of the barrel to the actuator 16 is exercised, the actuator 16 the wedge element 18 via the roller element guide 20 only more strongly pressed against the wall. If pressure is exerted by the side of the cartridge chamber, the wedge element is pressed even more strongly against the transition section.

The transition in the arms race can be designed arbitrarily. The transition can, as in 3a shown simplified, as a vertical edge, or for example, conical, curved or stepped.

As already described above, in one embodiment of the invention, the wedge member 18 be formed so that it rests at least with a portion in the transition. For this purpose, the wedge element 18 in addition a lead 19 have, for example, in 4 is shown.

A another embodiment The invention is preferably used in weapon runs a continuous diameter, d. H. Gun barrels without existing chamber. Also in this embodiment the above-described principle of self-locking effect is realized.

Here, the blocking element 2 in an embodiment of the invention, for example two wedge elements 18 on how much simplified in 3b shown. The two wedge elements 18 are arranged together and can also act as a wedge element 18 be educated. Be like in 3b two or more wedge elements 18 used, so can the wedge elements 18 be arranged at remote locations in the blocking element, preferably where where manipulation forces are to be expected. For example, in areas at the two ends of the barrier element.

The two wedge elements 18 are designed so that they are the blocking element 2 against Ma nipulationsversuche, similar to the blocking element in 3a , can secure from both sides. The wedge elements 18 be doing against the wall of the barrel 6 pressed to form a frictional engagement with this. Furthermore, the wedge elements form with their two bevelled insides 8a . 8b an additional locking mechanism in the direction of the cartridge chamber and in the direction of the mouth of the barrel.

As based on the schematic diagram in 3b shown, the extraction of the locking element 2 out of the barrel 6 from the mouth side, as from the side of the cartridge chamber, by the frictional engagement between the respective wedge element 18 and the run 6 prevented. In addition, this causes a beveled section 8a on the inside of the wedge element 18 that upon pressure on the actuator 16 towards the mouth of the barrel, the wedge element 18 via a roller element guide 20 even stronger against the wall of the barrel 6 is pressed and thereby the wedge element 18 even more strongly pressed against the barrel. Furthermore, the second beveled portion causes 8b on the inside of the other wedge element 18 that upon pressure on the actuator 16 towards the cartridge chamber, the wedge element 18 even stronger against the wall of the barrel 6 is pressed. In both cases, the frictional engagement is further enhanced or achieved a self-locking effect. Ie. an unauthorized person attempts to manipulate the blocking element in which he exerts pressure on the blocking element, he causes the wedge elements 18 via the actuating element 16 only be pressed even more strongly to the barrel. This is done regardless of whether pressure is exerted from the muzzle side of the barrel or from the cartridge chamber. In 3b forms, for example, a sleeve 13 with an additional stop 15 a holder so that the roller element can not be removed.

The actuator 16 for moving the wedge element apart 18 is designed to be at least partially within the wedge plates 18 can be arranged.

The actuator 16 preferably has a conical section in one embodiment of the invention 16a and a substantially cylindrical portion 16b on. The actuator 16 can be in one piece or, such. Tie 1 . 2 and 4 shown to be composed of several parts. The wedge element 18 can according to the actuator 16 with a conical section 18a and a cylindrical section 18b be provided.

The actuator 16 can preferably via a roller element guide 20 z. B. a linear ball guide 20 within the wedge element 18 be movably mounted, as in 4 shown. The roller element guide 20 can from at least one ball element 21 and a spring element 23 exist, as in the detail view in 4 is shown as an example. However, this ball guide is only one way for the average expert to the actuator 16 within the wedge element 18 to store or to lead. In addition to ball elements 21 are, for example, conical or cylindrical elements, as in 5 . 7 and 8th represented, or other role elements conceivable. The roller element guide 20 has the advantage that the wedge elements 18 can be moved apart without causing large frictional forces, as it would be the case when the actuator 16 over the entire surface of the wedge element 18 would be present.

For actuating the actuating element 16 an actuator is used. The actuator may for example consist of at least one wire element made of a shape memory alloy and / or at least one electric motor and / or at least one magnet arrangement, for example an electromagnet arrangement. However, the invention is not limited to the aforementioned embodiments fix an actuator. The listed embodiments are only a few examples of actuators for actuating the actuator. In addition to the examples mentioned, there are other options. Suitable are actuators that fulfill the above functions due to the given energetic conditions or force relationships.

To lock the locking element 2 becomes the actuator 16 between the wedge plate (s) 18 pushed, pushing them apart.

In an embodiment of the invention, in which the actuating element 16 a cylindrical and a conical section 16b . 16a are through the cylindrical portion 16b the wedge plates 18 initially moved apart.

The cylindrical section 16b can preferably be designed so that it the wedge plates 18 Although moved apart but not firmly against the barrel 6 suppressed. This has the advantage that no significant and unnecessary friction arises.

About the conical section 16a become the protrusions of the wedge plates 18 then pressed into the transition to the cartridge chamber, such as. In 1 . 2 . 5 . 7 and 8th shown. As a result, the barrel is reliably blocked by the wedge element 18 forms a positive connection / frictional connection with the cartridge bearing transition. The conical section 16a can vorzugswei be designed so that it is in a locked position with the wedge plates 18 essentially a diameter corresponding to the diameter of the sleeve 14 forms. This has the advantage that a possible wedging of the wedge plates 18 inside the sleeve 14 can be prevented. As described above, the wedge member further has the advantage that by the positive engagement with the transition, a pressure from the side of the cartridge chamber, the blocking element 2 can not remove, because the wedge element 18 at the transition abuts. Also, a pressure of the mouth side on the blocking element 2 is exercised, the blocking element 2 do not remove, because the wedge element 18 only firmer against the wall of the barrel 6 is pressed.

Accordingly, the actuator works 16 at a run 6 with a continuous diameter. In this case, the wedge element 18 no additional projections, but by the actuator 16 firmly against the wall of the barrel 6 pressed so that it forms a frictional engagement with the barrel, as in 3b shown.

In one embodiment of the invention, the actuating element 16 be actuated directly via the actuator or via a ball cage, as will be explained below. When using the above-described wire element while the length of the actuating element would have 16 be tuned with the length of the wire element.

In a further alternative embodiment, the blocking element 2 an additional pressure element, consisting of a first push rod 22 ,

The first push rod 22 is preferably at a front portion 22a with the actuating element 16 coupled. The actuator 16 is with its one end inside the push rod 22 movably guided, as in the 5 . 7 and 8th shown. For this purpose, the actuating element 16 in one embodiment, a transverse bore 24 on, in which a pen section 26 the push rod 22 is included. This will cause a relative movement between the first push rod 22 and the actuator 16 allows.

Preferably, in this case, a spring element 28 be provided, which is the first push rod 22 over the actuator 16 against the wedge element 18 pretensions, such as In 7 and 8th shown.

Compared to alternative embodiments of the invention in which the actuator 16 and the first push rod 22 are firmly connected or integrally formed, such a configuration has the advantage that the spring element 28 smaller temperature fluctuations or thermal diameter changes and the like can compensate.

The actuator 16 may in an alternative embodiment at its other end via at least one further spring element 30 with a stop or sleeve 14 be connected, such. In 4 shown. The spring element 30 serves to provide an additional force to the actuator 16 towards the mouth of the barrel 6 pushes back when the blocking element 2 is unlocked. This allows the wedge element 18 move into a position in which it releases the locking element or makes removable.

In a further embodiment of the invention, a further spring element 31 be provided that provides an additional force, the wedge element 18 Compresses when the blocking element 2 is unlocked and the actuator 16 from the wedge element 18 is moved out. The spring element 31 can do this on the sleeve 14 as a stop or, such. In 4 shown on a separate sleeve 33 be attached as a stop.

Furthermore, the first push rod 22 preferably with a ball-return lock 32 . 34 fitted out of a cage 32 which is around the front portion of the first push rod 22 is arranged and also at least one ball element 34 has, such. Tie 5 . 6 and 9 shown. The ball element (e) 34 is for example via a spring element outwards against the sleeve 14 pressed. The ball return lock 32 . 34 acts as a stop, preventing the push rod 22 out of the cage 32 and from the sleeve 14 can be pulled out. The ball return lock is against the sleeve 14 pressed when the conical section of the push rod 22 ( 9 ) against the ball (s) 34 suppressed. The ball return lock 32 . 34 However, leaves a relative movement between the first push rod 22 and the sleeve 14 towards the cartridge chamber too.

Furthermore, an embodiment of the invention in which, for example, a wire element is used as an actuator has a stop 35 up, with the push rod 22 is firmly connected. The actuator, made of a first wire element 42 is formed, is with the cage 32 the ball return lock and the stop 35 connected. In a preferred embodiment, further is a counter-attack 17 inside the sleeve 14 movably arranged, whereby the counter stop 17 via a second wire element (not shown) with the push rod 22 connected is.

Next is a first spring element 40 between the cage 32 the ball return lock and the counter stop 17 or a second push rod 36 arranged, such. In 2 shown. In the preferred embodiment, another second spring element 38 between counter-attack 17 and the push rod 22 or the stop 35 provided (cf. 2 and 9 ). Alternatively, the first spring element 40 also between the counter-attack 17 and the push rod 22 or the stop to be arranged and the second spring element 38 between the push rod 22 or their stop 35 and the ball cage.

The wire elements 42 are from a so-called shape memory alloy or so-called "shape memory alloy", for example, a nickel-titanium alloy. For example, such a shape memory alloy shortens when heated by about 4% or more.

To lock the locking element 2 in the barrel 6 introduced, this can be done by hand or via the control unit 4 , In particular, the introduction takes place with particularly long arms runs by means of the operating unit. In addition, an adapter can be provided, which is used in particular for longer arms runs.

An advantage of the blocking element 2 in which a wire element 42 is used as an actuator, that is the blocking element 2 can be operated by hand to lock the barrel. The mechanical locking step is preferably carried out by the user's hand. In principle, however, it is also conceivable that when using electric motors or magnet arrangements as an actuator, the blocking element is designed so that it can be locked by hand and is used only to unlock the actuator.

According to one preferred embodiment the authentication only for carried out the unlocking step and the lock can done without authentication. According to another preferred embodiment authentication takes place for both the unlocking and the unlocking for the locking step.

In the event that no authorization check or authentication is required for the purpose of securing or locking, the backup takes place manually after the blocking element has been introduced into the weapon barrel. When inserting the locking element 2 in the barrel 6 becomes, for example, the first pushrod 22 and thus the actuating elements 16 pressed in the direction of the cartridge chamber. In this case, the actuating element 16 in the wedge element 18 inserted so that it pushes it apart and blocks the barrel. The ball cage preferably also moves in the direction of the cartridge chamber and blocks the push rod as soon as the wedge element blocks the barrel. The electric motor or the magnet assembly could be provided so that they either also move along or remain stationary and pull back to unlock the push rod or the ball cage in the direction of the mouth of the barrel.

The Moving the ball cage basically has the big one Advantage that this be moved with a relatively small force can.

The blocking element 2 So it's the easiest way to block the barrel by hand, even if the electronics fail. Furthermore, no additional, special tool is necessary.

For actuating the actuator can in the blocking element 2 an electronics 9 be housed. This causes the blocking element, when using a wire element as an actuator, can be easily unlocked again. Be used instead of the wire element 42 By contrast, for example, an electric motor or a magnet arrangement z. B. used with a solenoid coil as an actuator, the actuator on the electronics 9 pressed to the locking element 2 to lock or unlock.

To block the barrel, the actuator, ie for example the electric motor or the magnet arrangement, actuates the actuating element 16 , The actuator pushes the actuator in the wedge element 18 one until the wedge element 18 firmly against the barrel 6 is pressed to form with this a frictional connection or a frictional / positive connection, depending on the type of run. In this case, the actuating element with a pressure element 22 be coupled as described above or the actuator and the pressure element or the push rod 22 be formed in one piece or only one actuator 16 be provided. This applies to all described embodiments.

To unlock the locking element, however, the actuator, be it a wire element and / or an electric motor and / or a magnet assembly, etc., must be via the electronics 9 be operated.

The Electronic 9 For example, this may be accommodated at a suitable location in the blocking element, this not necessarily being in the second push rod 36 must be, such as In 1 and 2 shown.

The Electronic 9 is for example a subminiature electronics. This is via an encrypted communication z. B. via a 1-wire data bus 48 with one in the control unit 4 located Electronics (not shown) in connection and can for example ensure a correct authentication of a user (see, eg. 1 . 2 and 10 ).

If a user is identified as a legitimate user, the electronics will do so 9 in that the actuator is the actuating element 16 from the wedge element 18 moved out, leaving the wedge element 18 or move the wedge plates in a position in which the locking element is removable from the barrel.

In the case where a wire element is used as the actuator, the electronics effect 9 to unlock the locking element 2 that the wire element 42 z. B. via a resistance heater (not shown) and thereby shortened. This, in turn, causes the ball backstop 32 . 34 at which the wire element 42 is fastened, is withdrawn towards the mouth of the barrel, as in 8th shown. This allows the first push rod 22 or the associated with her actuator 16 moved back or additionally via the spring element 30 be pushed back.

The actuator 16 is thereby at least partially from the wedge element 18 withdrawn. This results in that the wedge plates 18 move towards each other in a position in which the blocking element 2 is removable, as in 8th shown. This can be done on the wedge plates 18 additionally at least one spring element 30 be provided that the wedge plates compresses. Alternatively it can also be provided a spring element that, for example, at least partially encircling the wedge plates 18 is arranged, or a spring element as in 7 and 8th is shown. The spring element thereby causes the wedge plates 18 be compressed. This has the advantage that the wedge plates 18 can be moved together again as soon as the actuator 16 moved out between them.

To the blocking element 2 To protect against manipulation, as described above, another spring element 40 and a second wire element (not shown). The second spring element 40 For example, as described above, with one side on the push rod 22 or at the stop 35 and with the other side on the counter-attack 17 arranged (cf. 1 . 2 and 9 ).

Now try a third party, the blocking element 2 to unlock by holding the gun barrel 6 heated from the outside z. B. via a gas flame, then the first wire element 42 though shortened. At the same time, however, the second wire element (not shown) is also shortened.

This has the consequence that the spring element 40 a counterforce to the first spring element 38 generated. This causes the ball cage to move substantially, or hardly, backward, in the direction of the mouth of the barrel. This can cause the push rod 22 or the associated with her actuator 16 not so from the wedge element 18 be pushed out that this moves into a position in which the blocking element 2 is removable.

As in z. B. the 1 . 2 . 6 and 7 shown, the blocking element must 2 , to remove from the gun barrel 6 , first unlocked. This happens in the separate operating unit 4 with the blocking element 2 connected or coupled. Instead of a separate control unit 4 However, in principle is also conceivable, the control unit 4 directly in the blocking element 2 provided. In an alternative embodiment, the electronics 9 of the blocking element, instead of in the blocking element 2 even in the separate control unit 4 be accommodated, so that the blocking element substantially only has the mechanics.

The operating unit 4 and the blocking element 2 can do this via a clutch mechanism 12 be connected to each other. The separate control unit 4 has the advantage of being independent of the blocking element 2 can be stored.

That means that the control unit 4 after locking the gun barrel 6 , from the blocking element 2 can first be removed, for example, to be stored in a secure location.

Furthermore, only the blocking element can 2 as invisible backup in the barrel 6 leave with the advantage that the weapon can be easily transported and stored.

Another advantage is that there are a variety of weapons with corresponding blocking elements 2 can be secured, but for example via the same control unit 4 can be actuated ie locked and unlocked.

The blocking element 2 is usually weapon-specific for the caliber ie, for example, the running diameter and the cartridge bearing dimensions designed and can be adjusted, for example, in solid increments to the desired run lengths customer. The blocking element can optionally also be adapted to different run lengths by means of corresponding adapter elements. In a separate control unit such an adaptation to different types of weapons is not necessary.

Next the basic versions for Self-loading weapons such as pistols and rifles become variants for revolvers, as well as shotgun calibers (eg shotgun hunting weapons). hunting weapons are usually characterized by the fact that they are manually on the cartridge chamber side d. H. be loaded from the rear (Kipplaufprinzip), so that the locking element also to be installed.

The operating unit 4 can do this with all variants of the locking element 2 regardless of the number and type of weapons to be secured. This has the advantage, for example, that a control unit 4 for different, according to their use in certain weapons adapted locking elements 2 , can be used. This means, as already mentioned above, that in general at most the blocking element 2 must be adapted to a weapon type, but not necessarily a separate control unit 4 ,

The operating unit 4 has for this purpose the above-mentioned coupling unit 12 on, at any point with the blocking element 2 can be connected, if z. B. a data bus 48 the control unit 4 For example, a 1-wire data bus, with the electronics 9 of the blocking element 2 can be connected or the electronics to the actuator when the electronics 9 also in the control unit 4 is housed.

Preferably, a multi-level authentication method is selected to secure the system. Each control unit 4 can z. B. manufacturer provided with an individual password that in the control unit 4 is stored. This password is z. B. on each blocking element 2 transferred, the first time with this control unit 4 is locked. Each unlocking process is done by transmitting the password of the control unit 4 initiated. For unlocking is therefore just this control unit 4 suitable.

In addition, the use of a control unit 4 For example, be secured via an authentication method. This can be done as already described above via a PIN code and / or biometric data. Here, the PIN and the password of the control unit 4 preferably be changed by the user.

to Securing the system against a direct mechanical attack for example, by hitting, shaking, Drilling, milling, Eroding, etc., the following facilities are used.

Here, for example, a hard metal insert for the second push rod 36 used as well as a ceramic reinforcement. Furthermore, a self-locking wedge or a punch-through protection can be provided.

to Protection of the electronic system or communication channels (Password transmission) can the following facilities are provided.

For example, a mechanical protection can be provided by sub-miniature design and placement in the secure running area. Furthermore, an overvoltage protection of the blocking element electronics (not shown) can be provided.
