Description

The invention relates to an access blocking device for braking a vehicle when attempting to enter a protection zone without permission, wherein the access blocking device has a barrier element for blocking an access to the protection zone. The access blocking device may in particular be adapted to prevent a truck from entering a protection zone. In particular, the invention relates to a mobile access barrier device which can be set up as required.

Such access locking devices are already known. There are already concrete barriers to protect against terrorist attacks with vehicles that are placed in access roads and / or around a place, such as a major event in which many people reside, to block vehicles access to the place and this in an emergency to stop before reaching the protection zone.

However, it has been found that prior art access control devices are often not designed to prevent larger vehicles, such as trucks or vans, from traveling on, but often these access control devices are designed to decelerate smaller and, above all, lighter cars. They are therefore not suitable for preventing attacks by trucks.

Another associated problem is that the access barriers are often used only temporarily, for example, to secure a festival site or other venue. For this reason, access barrier device must be designed to be mobile, to be transported to different locations and there to be quickly established and dismantled. Ideally, therefore, the access control device need not be finally mounted on the job site and / or anchored to the ground to allow quick deployment.

Due to the mobile design of the access barrier device, these are often limited to a suitable maximum transport for a transport, so that again the problem goes along that these weight, for example, two tons, limited access locking devices are not suitable to a truck at the breakthrough in to prevent a protection zone as the truck literally catapults the access control device off in a collision therewith.

The present invention is therefore based on the object to overcome the aforementioned problems to set up protected from truck attacks protection zones by an access barrier device.

The object is achieved by the features of the independent claim 1. In particular, the invention proposes an access locking device of the type mentioned above for solving the problem, wherein the barrier element is connected to a loading element, wherein the loading element is arranged in a Anfahrtsbereich in front of the barrier element. The solution according to the invention has the advantage that a vehicle ascends against the loading element at least with the front wheels before a collision with the barrier element and thus loads the loading element and thus fixes it in the region of the load on the ground. Due to the connection between the loading element and the barrier element, the loading thus prevents an uncontrolled thrown-off of the barrier element, for example into the protection zone, after the impact of the vehicle on the barrier element. Rather, the vehicle is braked faster by the access barrier device, since it comes to blocking the front wheels of the vehicle. The access blocking device can thus contribute to improving the security measures around large events, so that it can be more effectively prevented that vehicle, especially trucks, can enter protected areas.

Advantageous embodiments of the invention will be described below, which may optionally be combined with the features of claim 1 alone or in combination with the features of other embodiments.

The loading element may be adapted to be drivable with a vehicle at least from its side facing away from the barrier element. By driving on the vehicle can apply the loading element with at least a portion of its weight.

According to one embodiment, the loading element can be configured at least partially elastically. As a result of the embodiment of the invention, a part of the kinetic energy of the vehicle can thus be absorbed by the load element and thus the vehicle can be braked much more quickly and with a shorter braking distance than in the case of previously known safety devices.

Upon a first impact of a vehicle with the barrier element, an impulse or at least a portion of the vehicle's pulse may be transmitted to the barrier element, then move away from the vehicle in a thrust direction, the barrier element decelerating due to the resilience of the loading element is then moved back against the direction of impact and / or the direction of travel of the vehicle back to the vehicle. The barrier element therefore subsequently collides with the vehicle at least a second time, resulting in a gradual, iterative deceleration of the vehicle. Depending on the speed and / or weight of the vehicle, the vehicle may possibly collide several times with the barrier element until it is finally completely decelerated. Due to the elastic design of the loading element, it is possible to use barrier elements whose respective weight is significantly lower than the weight of a vehicle.

In order to produce a heavy and robust barrier element relatively inexpensively, it may be expedient if the barrier element is designed as a concrete body. The density of the barrier element may be, for example, at least 2500 kg / m ³ . A tensile strength of the barrier element may be, for example, at least 2.5 N / mm ² .

The loading element can beispielswese be designed as at least one mat and / or plate. In order to better avoid damage to the loading element, the loading element is designed particularly tear-resistant. For example, it may have a tensile strength of at least 3000 N / cm ² . The impact of a moving lorry on a stationary obstacle can result in a force of up to 650,000 N, the resulting energy being at least partially absorbed by the loading element.

A particularly stable and tear-resistant configuration can provide that the loading element is at least partially made of a fabric. For example, the fabric may be a rubber-coated fabric and / or an elastomer fabric, such as a rubber fabric, and / or a plastic fabric. In this case, a maximum extensibility of the loading element in a normal vector direction, which is aligned perpendicular to an impact surface of the barrier element, be given. As a rule, a vehicle will approach the barrier element almost vertically or slightly obliquely. By the above-mentioned orientation, a maximum extensibility can be exploited, resulting in a more effective braking of the vehicle. Alternatively or additionally, a distensibility of the loading element in at least two, in particular aligned perpendicular directions, be possible. Thus, a certain elasticity of the loading element can be ensured even if the vehicle ascends obliquely on the barrier element. The loading element may in particular have a tissue designed at least in two layers. Thus, the loading element can be made particularly stable.

In order to be able to push away the barrier element sufficiently far from the vehicle after the impact and at the same time to prevent the barrier element from penetrating into the protection zone, a limit of elasticity of the loading element can be set such that an elongation of the loading element by at least 5%, in particular by at least 10 %, preferably at least 20% or 30%, is possible without causing irreversible deformation and / or tearing of the loading element.

In a particularly stable, yet simple and relatively inexpensive to produce embodiment of the access barrier device, the loading element may have a mesh structure with square and / or square single mesh, with a majority of the diagonals of the individual meshes parallel or approximately parallel to one or the previously mentioned normal vector direction, the is aligned perpendicular to an impact surface of the barrier element run. Alternatively or additionally, a maximum elasticity of the barrier element in the direction of the diagonal of the mesh can be given. A strain path of the loading element can thus be optimally utilized to decelerate the vehicle by the kinetic energy of the vehicle is at least partially absorbed by the loading element.

In order to prevent the barrier element from tipping over due to loading of the loading element by a vehicle, it may be advantageous for the loading element to lead away from the barrier element at a lower edge of the barrier element.

A particularly stable connection between the barrier element and the loading element can be achieved in that the loading element forms or has a, in particular expandable, band loop which runs around the barrier element at least once. In the event of a collision of a vehicle with the barrier element, the part of the loading element which serves for fastening to the barrier element can thus also expand. Alternatively or additionally, the loading element can be connected to the barrier element via at least one holding strap that at least partially spans the barrier element. It may be particularly advantageous when the tether is formed as an elastic fabric tape and / or when the barrier element rests in a resting state at least partially on the loading element. This can be a vehicle in the event of an impact on the barrier element, load the loading element in the approach area in a loading zone and thus hold the loading element at the loading zone on the ground. The load takes place, for example, at least by the front wheels.

According to one embodiment, the barrier element may have a weight of at least two tons. Thus, it is still possible to design the access barrier device mobile, wherein the weight of the barrier element is nevertheless sufficient to brake an approaching vehicle. In order to be able to avoid damage to the barrier element in the event of an impact, the barrier element can be made free of cavities, at least in the area of one or the aforementioned impact surface.

In order to be able to better ensure that the load-access element is loaded on the access-blocking device even in the case of an oblique approach direction of a vehicle, the loading element can be wider than one or the previously mentioned impact surface of the barrier element, at least in the approach area. The vehicle will thus, in the ideal case, inevitably load the loading element with at least one wheel before it impacts the barrier element.

In order to be able to even better avoid slippage of the load element from the ground during loading of the load element by a vehicle, the load element, in particular at least in the region of one or the load zone, can have an anchoring device, wherein the anchoring device has teeth extending from the underside of the anchoring device protrude and / or are inclined at an angle in the direction of the barrier element.

The anchoring device can be arranged on an underside of the loading element and / or on an upper side of the loading element. When loaded by a vehicle, the teeth hit the ground and reduce slippage in the direction of travel of the vehicle. Part of the kinetic energy can thus be transferred to the subsurface. When loading the anchoring device arranged at the top, the teeth strike first through the material of the loading element and then into the substrate.

In order better to prevent destruction of the loading element and / or wheel spin of a vehicle, an increase in friction and / or wear protection can be arranged or formed on an upper side of the loading element in the approach area, in particular at least one or the aforementioned loading zone , This can be achieved, for example, by the fact that the increase in friction and / or the wear protection is / are formed by the application and / or incorporation of pebbles and / or by the application and / or introduction of a metal friction plate on or into the loading element. Alternatively or additionally, this can also be achieved by the coating described herein. The wear protection may, for example, have teeth which protrude from one, in particular the surface of the loading element already mentioned above. The teeth may have a triangular cross-section and / or be pointed.

In order to better prevent tipping over of the access barrier device after a collision of a vehicle, a height of the barrier element on a side facing away from one or the previously mentioned impact surface may reduce with increasing distance from the impact surface. Alternatively or additionally, the barrier element may be wedge-shaped on a side remote from one or the impact surface. The barrier element can thus have a bevel on its side facing away from the impact side. This embodiment has the advantage that thereby at least a part of the kinetic energy of the vehicle can be better guided into the ground and absorbed by it.

According to one embodiment of the access barrier device, the loading element may have a non-slip coating. It can be provided that the coating of the loading element has a hardness of 25 to 60 Shore, in particular of 60 Shore, at least in the region of, for example, the loading zone already mentioned above. For example, it may be a non-slip rubber coating. Alternatively or additionally, the coating of the loading element may have a material thickness of at least 3 mm, at least in the area of one or the loading zone. In particular, the material thickness can be in a range of 3 to 5 mm.

In order to be able to detect a destruction, such as a cutting, of the loading element in order to be able to replace or repair the access blocking device as quickly as possible, the access blocking device can have an electronic tamper protection, by means of which damage to the loading element can be detected. The manipulation protection can have at least one sensor unit, which is arranged on or in the loading element, for example, is embedded, and a transmitter unit, by means of which in case of damage of the Loading element is sent a signal about the presence of damage. The access blocking device may additionally comprise a location determination module, preferably a GSM / GPS direction-finding transmitter, by means of which the location coordinates of the damaged access blocking device can be determined and sent by the transmitter unit. A GSM / GPS direction-finding transmitter has the advantage that it can make a call via a SIM card, for example to a police station, in order to report the damage. By locating simultaneously, the damaged access barrier can be quickly found and repaired.

The invention also relates to an access blocking system having at least two access blocking devices as described and claimed herein, wherein the at least two access blocking devices are connected to each other via a coupling device. The system thus makes it possible to use a plurality of interlocking access locks to shut off a safety zone by coupling them together to form a series of access locks. Due to the coupling of the access blocking devices, individual access blocking devices can not be pushed out of the assembly in a collision, but are additionally held next to the loading element by adjacent access blocking devices.

To support the above-described iterative braking operation, the coupling device may be at least partially elastic. For example, the coupling device may comprise a connecting piece made of a fabric, in particular comprising a rubber fabric and / or plastic fabric.

The invention will now be described in more detail with reference to several embodiments, but is not limited to these embodiments. Further exemplary embodiments result from the combination of the features of one or more claims with one another and / or with one or more features of the exemplary embodiments.

In the 1 to 4 an access locking device, generally referred to as 1, is shown. The access barrier device 1 is set up to vehicles 2 which unauthorizedly attempt to penetrate into a security area shut off by means of the access barrier device 1 after a collision with the vehicle 2 decelerate. Through the access barrier device 1 Thus, the unauthorized entry into a protection zone, which may be a venue for example, can be prevented by the vehicle 2 is brought to a stop before. The access barrier device 1 is therefore particularly suitable for the defense against terrorist attacks with vehicles 2 ,

The access barrier device 1 has a barrier element 3 which obstructs access to the protection zone as an obstacle. The access barrier device 1 further indicates with the barrier element 3 connected load element 4 on. The loading element 4 is on a subsoil in a approach area 5 in front of the barrier element 3 arranged. Because the loading element 4 is provided for covering a substrate and the vehicle 2 can be drivable, it can be designed flat.

To get a kinetic energy of the vehicle 2 after the collision of the barrier element 3 with the vehicle 2 through the access barrier device 1 can better absorb and deduce, the load element 4 be at least partially elastic.

At a first impact of a vehicle 2 on the barrier element 3 Thus, a pulse or at least part of the pulse of the vehicle 2 on the barrier element 3 be transmitted. The barrier element 3 then moves away in an impact direction 6 from the vehicle 2 , passing through the front wheels of the vehicle 2 the load element 4 in the approach area 5 loaded and ideally fixed to the ground. To a sliding away of the load element 4 after the shock to avoid, at least the top 17 the loading element 4 be non-slip coated. The barrier element 3 becomes due to the resistance of the loading element increasing with the distance 4 decelerated and by means of the load element 4 generated clamping force in a direction opposite to the original impact direction 6 on the vehicle 2 moved back. This leads to a renewed collision of the vehicle 2 with the barrier element 3 so that a re-uptake of kinetic Energy takes place. This can be done, for example, by a deformation of the vehicle 2 and / or dissipating the energy into the substrate and / or by reexpansion of the loading element 4 respectively.

Under certain circumstances, by a renewed impulse transmission of the vehicle 2 on the barrier element 3 Therefore, the deceleration process described above is repeated at a lower amplitude, thus resulting in a kind of iterative deceleration of the vehicle 2 comes. This can lead to a decomposition of a first large pulse into several smaller pulses.

The loading element 4 can be configured for example as a mat or plate. It has proved to be advantageous that a length of the mat or the plate and / or the approach area 5 at least 2 meters. In particular, the mat or the plate and / or the approach area 5 have a length of 2 meters to 6 meters.

The barrier element 3 can be advantageously designed as a concrete body. The concrete body can have a density of at least 2500 kilograms per cubic meter (kg / m ³ ). Its tensile strength can be about 2.5 Newton per square millimeter (N / mm ² ), so that the barrier element 3 is designed to be particularly stiff. The concrete body may, for example, have a minimum size of width 1.20 meters × length 1.60 meters × height 1.00 meters, but is not limited to this geometry and / or these dimensions. In particular, the barrier element 3 have a triangular side surface and / or a triangular cross-section.

The loading element 4 can be at least partially made of a fabric 7 be prepared. The tissue 7 For example, a rubber-coated fabric 7 and / or an elastomeric fabric, in particular a rubber fabric, and / or a plastic fabric. The use of a tissue 7 for the production of the loading element 4 may therefore be advantageous because this is particularly durable and / or has a non-slip surface and it can adapt to unevenness and / or the shape of a substrate due to its elasticity. By underlaying at least a part of the loading element 4 under the barrier element 3 thus a safe footprint for the barrier element 3 be configured by bumps are compensated, causing a tipping over of the barrier element 3 can be better prevented after a collision. In addition, a frictional resistance of the attached to the substrate barrier element 3 by underlaying a part of the loading element 4 be achieved, reducing the braking effect of the system on a vehicle 2 is still increased.

It is also particularly advantageous that the loading element 4 due to its elasticity after a shock kinetic energy of the vehicle 2 can record. This leads to a much faster deceleration and a braking distance of the vehicle 2 can be significantly reduced compared to previously known solutions.

The loading element 4 For example, it can at least partially consist of a fabric, for example the one already mentioned, having a lattice structure and / or mesh structure 7 be prepared, which is formed of a plurality of stitches. The individual meshes of the loading element 4 For example, they may be rectangular or square. By an appropriate orientation of the loading element 4 can be a maximum extensibility of the loading element 4 in a normal vector direction 8th , perpendicular to an impact surface 9 of the barrier element.

The impact surface 9 may include a material reinforcement and / or a protective cover to prevent a vehicle from impacting 2 better to avoid damage.

In order to start a vehicle at an angle 2 on the access barrier device 1 nevertheless, in particular perpendicular to the direction of impact 6 extending, moving away the barrier element 3 from the vehicle 2 To be able to achieve a stretchability of the loading element 4 be possible in at least two, in particular mutually perpendicular directions.

A particularly stable, yet elastic design of the loading element 4 can be achieved in that this at least two-ply tissue 7 , in particular a rubber fabric and / or a plastic fabric is made. In particular, the loading element 4 be designed in three layers or even four layers. The loading element 4 becomes more stable the more layers it has. However, too many layers can negatively affect the elasticity.

A limit of elasticity of the loading element 4 can be arranged so that an elongation of the loading element 4 by at least 5% relative to its original length is possible. It may be particularly expedient if the elastic limit of the loading element is set up such that an elongation of 10%, preferably even at least 20% or 30%, is possible without irreversible deformation and / or tearing of the loading element.

The tensile strength of the loading element 4 For example, it may be at least 3000 Newton per square centimeter (N / cm ² ).

In particular, the loading element 4 be made at least partially from already known materials that are also used in conveyor belts for heavy goods conveyors.

For example, the loading element 4 be at least partially made of a heavy duty EPP textile conveyor belt. Examples include the products marketed by Continental under the CON-MONTEX and CON-BITEX brands which are designed to carry heavy goods such as boulders, logs and the like, but have not heretofore been used for the purpose of access barriers.

Alternatively or additionally, the loading element 4 be at least partially made of already known in conveyor systems PVC and / or PU conveyor belts.

Furthermore, the loading element 4 alternatively or additionally be made at least partially of a polyester / polyamide fabric.

In conveyor systems also known already multi-layer belts, ie in particular 2-layer belts, 3-layer belts, 4-layer belts and / or 5-layer belts, which may also be provided for the production of the loading element.

The loading element 4 can, as described above, have a mesh structure with square or square single meshes. A large part of the diagonals of the individual meshes of the mesh structure may be parallel or at least approximately parallel to the normal vector direction 8th be aligned. The maximum elasticity of the barrier element 3 is arranged so that it runs in the direction of the diagonal of a majority of the mesh, so that in a frontal driving of the vehicle 2 on the access barrier device 1 a maximum elasticity is given.

To a particularly stable state of the barrier element 3 To achieve, it may be advantageous if the loading element 4 at a lower edge of the barrier element 3 from the barrier element 3 in the approach area 5 projects.

To connect the barrier element 3 with the loading element 4 can the load element 4 a stretchable band loop 10 at least once around the barrier element 3 is led around. The band sling 10 thus can also absorb kinetic energy. A width of the band loop 10 may be less than or equal to the width of the loading element 4 in the approach area 5 be.

It is also conceivable that as an alternative or in addition to the band loop described above 10 one or more straps 11 are provided to the barrier element 3 over the strap or the 11 with the loading element 4 connect to.

A holding strap 11 can be formed for example as an elastic fabric tape. This has the advantage that it is also particularly tear-resistant and in turn a part of the kinetic energy of the vehicle 2 can record.

At rest, the barrier element lies 3 at least partially on the loading element 4 on. Drives a vehicle 2 in the approach area 5 with its front wheels and thereby loaded the load element 4 in the area of a loading zone 12 so becomes the load element 4 in the area of the loading zone 12 held on the ground. Once the vehicle 2 For example, with a bumper on the impact surface 9 are present, those with the load zone 12 connected front wheels of the vehicle 2 blocked because of a frictional connection.

To by means of the access lock device 1 especially large and heavy vehicles 2 to be able to brake, it is expedient if the barrier element 3 has a weight of at least 2 tons. Preferably, the barrier element 3 more than 2 tons, such as 2.5 or 3 tons or more. By the impact of a truck on the impact surface 9 enormous forces act on the barrier element 3 , In order to avoid destruction by the impact, the barrier element 3 at least in the area of the impact surface 9 be configured void-free. In addition, by a void-free design, a higher density of the barrier element 3 be achieved to absorb energy.

A width of the loading element 4 at least in the approach area 5 wider than the impact surface 9 of the barrier element 3 be educated.

In order to achieve an even better energy dissipation via the substrate, it may be advantageous if the loading element 4 at least in the area of the loading zone 12 an anchoring device 13 having. The anchoring device 13 can teeth 14 exhibit from the bottom 15 the anchoring device 13 protrude and / or at an angle in the direction of the barrier element 3 So in the direction of impact 6 , are inclined. After driving up and loading the loading zone 12 through the vehicle 2 will the teeth 14 struck into the ground and prevent or reduce a continued slippage of the load element 4 in the area of the loading zone 12 on the ground.

The anchoring device 13 can at a bottom 16 of the loading element 4 be arranged. Alternatively or additionally, the anchoring device 13 also on a top 17 be arranged of the loading element. This can be achieved for example by a second anchoring device.

At a load one at the top 17 arranged anchoring device 13 through a vehicle 2 become the teeth 14 first by the material of the loading element 4 through the underground. Thus, an even better fixation of the loading element 4 possible on the underground.

At least in the area of the previously mentioned loading zone 12 can be a friction increase 18 and / or wear protection 19 be arranged. By the friction magnification 18 may be a slipping of the wheels of a vehicle 2 from the top 17 of the loading element 4 better prevented, so after concern of a bumper of the vehicle 2 at the impact surface 9 the front wheels of the vehicle 2 completely block. By a wear protection 19 can the load element 4 from damage, especially by the wheels of the vehicle 2 , better avoided.

The friction magnification 18 and / or the wear protection 19 can / can for example by the application and / or incorporation of pebbles and / or by the application and / or introduction of a metal friction plate 20 on or in the loading element 4 be formed.

To overturn the barrier element 3 after a collision of a vehicle 2 Being able to better prevent it can be a focal point of the barrier element 3 in the direction of the impact surface 9 to be relocated. This can for example be done by the barrier element 3 on one of the impact surface 9 turned away side in its height 21 with increasing distance from the impact surface 9 reduced. The barrier element can therefore be a slope 29 exhibit. Thus, the barrier element 3 wedge-shaped. After a collision, a part of the kinetic energy can thus be transferred via a support surface 30 of the barrier element 3 be transferred to the underground. The bearing surface 30 For example, it may be larger than the impact area 9 be designed.

The impact surface 9 can be relative to the ground and / or the load element 4 be arranged vertically or obliquely. In the oblique orientation can between the impact surface 9 and the substrate and / or the loading element 4 an angle of more or less than 90 degrees may be provided. In a thrust direction 6 inclined orientation of the impact surface 9 can be a kinetic energy of the vehicle 2 be better dissipated and absorbed into the underground. In one opposite to the direction of impact 6 inclined orientation of the impact surface 9 a kinetic energy can be better converted into potential energy, in particular by the barrier element 3 lifted off the ground.

The loading element 4 can at least in the area of the loading zone 12 a coating 22 , For example, for the aforementioned wear protection 19 and / or the aforementioned friction increase 18 , exhibit. The coating 22 may have a hardness of 25 Shore (A or D) to 60 Shore (A or D), especially 60 Shore (A or D). When coating 22 For example, it may be a rubber coating. The material thickness, ie the thickness of the coating 22 , may be at least 3 mm, preferably 3-5 mm. Suitable rubber coatings and / or materials for making the loading element 4 may be a material or a combination of a plurality of materials selected from the group consisting of natural rubber, silicone, ethylene-propylene-diene rubber, butyl rubber, polyethylene, in particular chlorinated polyethylene, epichlorohydrin rubber and / or polyurethane, the coating not being based on these is limited.

To willfully destroy, such as cutting, the load element 4 To be able to recognize immediately to take countermeasures, the access lock device 1 an electronic manipulation protection 23 by which damage to the loading element 4 is detectable. The manipulation protection 23 can at least one sensor unit 24 have, on or in the loading element 4 is arranged. For example, this can be embedded between two material stores.

The sensor unit 24 For example, it can be formed over a plurality of cable strands, in particular in or parallel to or inclined to the normal vector direction. After severing a cable harness, this can thus be done by the sensor unit 24 be recognized. The manipulation protection 23 further includes a transmitter unit 25 on, by means of which upon detection of a damage of the loading element 4 through the sensor unit 24 a signal of the presence of damage is sent to a specific location, such as a police station, automated.

Alternatively or additionally, it may be advantageous if the access barrier device 1 a location determination module 26 by means of which the location coordinates of the damaged access device 1 determined and with the transmitter unit 25 can be shipped. Thus, as soon as possible damage to a certain access barrier device 1 be detected and corrected.

The invention also relates to an access barrier system comprising a plurality of the access locking devices described and claimed herein 1 having. The individual access barriers 1 can be arranged side by side and via a coupling device 27 be connected to each other. The adjacent impact surfaces 9 ideally form a shield of the protection zone. It may also be useful if the loading elements 4 the individual access barriers 1 at least partially overlapping.

The coupling device 27 may also be at least partially elastic. This can be implemented, for example, by a connector formed of a fabric, such as a rubber fabric and / or plastic fabric. The connector may each have a free end in on the sides of the barrier elements 3 trained mounts be fixed so that the individual access locking devices 1 are connected to each other by means of the connector via their brackets.

In 5 is a barrier element 3 with a shaft formed on its back 28 shown. In this shaft 28 For example, the transmitter unit 25 and / or the location determination module 26 be used. Thus, the manipulation protection 23 protected in a crash.

The electronic manipulation protection 23 In addition, it can have its own energy source, so that autonomous operation, in particular without connection to an external power supply, is possible.

In addition, it can be provided that the access barrier device 1 an additional shock sensor, which is a collision of a vehicle 2 detects and then immediately an emergency call on the transmitter unit 25 For example, to a police department is deductible so that emergency services can be called to the attack site as soon as possible.

The invention thus relates to an access locking device 1 to stop a vehicle 2 when attempting to enter a protected zone unauthorizedly, the access blocking device 1 a barrier element to be placed as an obstacle in a driveway 3 and one with the barrier element 3 connected, flat trained loading element 4 having, wherein the loading element 4 a journey area 5 trains, in the approach direction of the vehicle 2 in front of the barrier element 3 is arranged.
