Description

[0001] The invention relates to a mobile vehicle security barrier for blocking vehicles, in particular for the temporary or medium-term blocking of access roads and for protecting crowds from unauthorized vehicle access or targeted attacks with vehicles. Advantageously, the mobile vehicle security barrier can achieve a high stopping effect while being easy and quick to install without heavy equipment. The invention further relates to a barrier element for blocking vehicles, a modular system comprising a barrier element, and a modular system comprising a mobile vehicle security barrier.

[0002] Mobile road barriers serve to protect various locations from unauthorized access or targeted attacks with vehicles. Since such attacks often involve vehicles of considerable weight and mass, it is essential that mobile road barriers are capable of withstanding significant impact forces and reliably preventing breaches.

[0003] Concrete blocks are used, for example, to block the movement of vehicles, as their high mass is intended to create an effective barrier. However, the use of such concrete blocks has significant drawbacks. In particular, their transport is complex and expensive due to their weight. Furthermore, experience has shown that even massive concrete blocks often cannot withstand the forces generated by collisions with heavy and fast vehicles. While using larger and heavier blocks can increase their protective effect, this further complicates transport and placement. Another disadvantage is that individually placed concrete blocks can be displaced by the impact forces or even become dangerous projectiles.

[0004] From EP 3 575 493 A1, a road barrier for quick and easy assembly and disassembly is known, comprising at least two modular units. Each modular unit has a base bar and a lever bar connected to the base bar, which protrudes from the ground when assembled. The modular units are connected to each other via connecting rods, which ensure horizontal coupling of the units. By connecting a large number of modular units, larger areas can also be blocked off. The angle between the base bar and the lever bar is adjusted such that if a vehicle strikes the road barrier at the lever bar at a corresponding internal angle, the lever arm formed by this internal angle causes the modular unit to tip over, and the base bar then strikes the vehicle from below, jacking it up, tearing it open, or tipping it over.A disadvantage is that the locking effect is insufficient for large and fast vehicles.

[0005] A mobile road barrier module for blocking a moving vehicle is known from DE 20 2023 103 177 U1. This module comprises a base resting on the ground and a pivoting barrier element. The pivoting barrier element can be fixed in a suitable position to block an approaching vehicle. When the barrier element is folded, the mobile road barrier module is easy to transport. In the event of a vehicle impact, a spike connected to the base can penetrate the ground and anchor the road barrier module. A disadvantage of this type of barrier is that it cannot absorb sufficient energy from large and fast vehicles, so that a breach of the barrier is not reliably prevented.

[0006] German patent DE10 2020 117 461 B3 discloses a road barrier comprising a foundation and a bollard barrier element arranged in a recess of the foundation. The bollard barrier element is constructed from several plates, enabling it to absorb and dissipate the force generated by a vehicle impact. A disadvantage of such a foundation is that it always necessitates excavation into the ground.

[0007] Furthermore, numerous crash tests have shown that various mobile road barriers are unable to adequately absorb and dissipate the forces generated, particularly in collisions with very heavy and / or high-speed vehicles. In addition, many of the known road barriers have complex designs, resulting in high acquisition and manufacturing costs. Moreover, some models, due to their size and weight, require the use of heavy equipment, such as a crane, to position them, further complicating and increasing the cost of setup.

[0008] The invention is therefore based on the objective of providing a device that overcomes the disadvantages of the prior art, in particular providing a mobile road barrier that has a high stopping effect even in collisions with heavy and fast vehicles, is easy and quick to assemble and disassemble, does not require the use of heavy equipment and is cost-effective to manufacture.

[0009] The problem is solved by a device with the features of the independent claims. Further developments are specified in the dependent claims.

[0010] A first aspect of the invention relates to a mobile vehicle safety barrier for blocking a vehicle traveling in a direction R, comprising at least two barrier elements preferably spaced apart from each other and at least one connecting unit.

[0011] The barrier elements are rigidly and preferably detachably connected to one another by means of at least one connecting unit. Thus, the mobile vehicle safety barrier is advantageously a modular and mobile vehicle safety barrier.

[0012] The barrier element has a base for driving over by the front tires of the vehicle with an underside for at least partial contact with the ground and a force dissipation element projecting from the base.

[0013] The force dissipation element has a deflection edge, preferably pointing against the direction of travel, which is arranged at a height above the ground of 40 cm to 200 cm, i.e., a distance to the plane of the underside of 40 to 200 cm, preferably 60 to 130 cm.

[0014] In the assembled state, the rebound edge is oriented horizontally and perpendicular to the direction of travel, preferably having a length of at least 35 cm, preferably at least 45 cm. The rebound edge can also deviate from a horizontal direction, in which case it forms an angle of no more than 20° with a horizontal line.

[0015] The rebound edge can be defined as an edge or as a narrow surface of a maximum of 0.05 m. 2 , preferably a maximum of 0.03 m 2 , be trained.

[0016] The force-dissipation element comprises at least three spaced-apart, rigidly connected, parallel, plate-shaped rib elements arranged in a plane, the outermost rib elements being spaced at least 25 cm apart, preferably at least 40 cm apart, and particularly preferably between 30 cm and 90 cm apart. This spacing of the outermost rib elements is the distance between the two furthest rib elements of a barrier element.

[0017] The plate plane is arranged parallel to the direction of travel (R), so that a vehicle approaching the barrier element approaches the end faces of the rib elements, which advantageously enables efficient force dissipation.

[0018] The base has a top surface on one side facing away from the underside, allowing the vehicle's front tires to drive onto it in sections. The rear end of the base, pointing in the direction of travel, is rigidly connected to the force-dissipation element. According to an advantageous embodiment, the top surface has, at least in sections, a ramp-like surface that rises in the direction of travel to facilitate the vehicle's entry onto it.

[0019] Each of the barrier elements preferably has lifting arm receiving elements in the base, for example, openings for receiving at least one transport aid arm for receiving a pallet truck, and at least two wheel receiving elements, for example, wheel engagement openings, for attaching at least one wheel each.

[0020] The lifting arm mounting elements and the wheel mounting elements are preferably designed to make the barrier elements movable for transport and positioning by means of a pallet truck and wheels, and these transport aids are removed or deactivated when the barrier is erected.

[0021] A further aspect of the invention relates to a barrier element for blocking a vehicle traveling in a direction R, comprising a base for partial traversal by at least one front tire of the vehicle and a force-dissipation element projecting from the base. The force-dissipation element has a deflection edge, directed against the direction of travel and oriented horizontally and perpendicularly to the direction of travel, at a height of 40 cm to 200 cm. The force-dissipation element has at least three spaced-apart, rigidly connected, and parallel plate-shaped rib elements, which are aligned in a plane. The plane of the plate is arranged parallel to the direction of travel.Two outer rib elements, i.e., the two rib elements furthest apart from each other of the barrier element, have a distance of at least 25 cm, preferably at least 40 cm, and particularly preferably a distance in the range of 30 cm to 90 cm.

[0022] The base has a bottom surface for at least partial contact with the ground and a top surface. The rear end of the base, in the direction of travel, is rigidly connected to the force-dissipating element, with the connection preferably being made on the top surface of the base.

[0023] On the barrier element, preferably on the base, at least one lifting arm receiving element, for example an engagement opening, for receiving at least one transport aid arm for receiving a lifting trolley, is arranged, and at least two wheel receiving elements, for example wheel engagement openings, are arranged on the barrier element for attaching at least one wheel each.

[0024] The lifting arm mounting elements and the wheel mounting elements are designed to make the barrier elements movable for transport and positioning by means of a pallet truck and the wheels, and these transport aids are removed or deactivated when the barrier is erected.

[0025] All features of the barrier element disclosed in connection with the mobile vehicle safety barrier also apply accordingly to the barrier element as an individual component. All features of the barrier element described in the context of the mobile vehicle safety barrier can therefore be applied equally to a single barrier element.

[0026] Another aspect of the invention relates to a modular system comprising ◯ a barrier element described herein, ◯ two wheels for detachable attachment to the wheel mounting elements, which are preferably attachable to the rear end of the vehicle safety barrier in the direction of travel, ◯ a transport aid arm for detachable attachment to one of the lifting arm mounting elements, comprising an engagement module for the engagement of a pallet truck and ◯ a two-wheeled pallet truck for lifting the barrier element, at least in sections, which is designed to engage the engagement module of the transport aid arm, ◯ wherein the wheels and the transport aid arm are preferably intended exclusively for the transport and positioning of the barrier element and can be removed or deactivated in the assembled state, for example by folding it up.

[0027] Another aspect of the invention relates to a modular system comprising • a mobile vehicle safety barrier as described herein, • two wheels for detachable attachment to the wheel mounting elements, which are preferably attachable to the rear end of the vehicle safety barrier in the direction of travel, • a transport aid arm for detachable attachment to one of the lifting arm mounting elements, comprising an engagement module for the engagement of a pallet truck and • a two-wheeled pallet truck for lifting the mobile vehicle safety barrier, at least in sections, which is designed to engage the engagement module of the transport aid arm, • wherein the wheels and the transport aid arm are preferably intended exclusively for the transport and positioning of the vehicle safety barrier and are removed when assembled.

[0028] Another aspect concerns a modular system, featuring ◯ a mobile vehicle safety barrier as described herein, ◯ two wheels which are detachably attached to the wheel mounting elements, which are preferably attached to the rear end of the vehicle safety barrier in the direction of travel, ◯ a transport aid arm which is detachably attached to one of the lifting arm mounting elements and ◯ a two-wheeled pallet truck for lifting the vehicle safety barrier, at least in sections, which engages with an engagement module of the transport aid arm. Advantages

[0029] Advantageously, the device according to the invention, in particular the mobile vehicle security barrier, the barrier element, and the modular system, withstands even higher impact loads. Upon impact, the attacking vehicle is severely damaged and additionally slowed down by the counterweight of the device according to the invention. Thus, these mobile road barriers offer a high level of protection and minimize the risks to people and infrastructure. The physical barrier is designed for high impact speeds and reliably protects against unauthorized vehicle access and targeted vehicle attacks.

[0030] The modular device, and in particular the modular system, can be conveniently assembled manually within minutes, without heavy equipment. This ensures maximum operational flexibility even under time pressure. The modular design allows for adjustments to the barrier width as needed, providing barrier-free access for pedestrians, wheelchair users, and strollers.

[0031] The provided detachable transport aids advantageously ensure simple and quick transport, while the device cannot be manipulated in the erected state without the attached transport aids. Definitions:

[0032] For the purposes of the disclosure, the direction of travel R denotes a defined reference direction used to describe the position and orientation of individual elements of the barrier element. The direction of travel R corresponds to the direction in which a vehicle would approach the barrier element when it is erected. Even when the barrier element is not erected, the direction of travel R is used as a reference to unambiguously describe the relative arrangement and orientation of components.

[0033] For the purposes of the invention, a barrier element is a structural unit for securing traffic routes or areas against vehicles driving over or entering them. It has a base that rests on the ground and at least one force-dissipation element that dissipates the forces occurring upon impact in a controlled manner. The force-dissipation element has a rebound edge that generates an effective stopping effect upon impact.

[0034] According to the invention, a force dissipation element is an integral component of the barrier element, serving to selectively dissipate forces, particularly those generated by a vehicle impact, into the ground or adjacent structures. A force dissipation element may include ribs, reinforcements, or supports. The force dissipation element features a deflecting edge. This edge protrudes and enables significant damage to an impacting vehicle or object. The force dissipation element is preferably made of steel.

[0035] For the purposes of the invention, a connecting unit is a structural element used to mechanically connect two barrier elements. The connecting unit ensures a stable and secure connection, can be detachable or permanent, and is designed to withstand the loads encountered. Advantageously, the two barrier elements connected by the connecting unit are rigidly connected to each other and cannot twist relative to each other, even under high force. A connecting unit is detachably or permanently connected to a first barrier element and detachably or permanently connected to a second barrier element.

[0036] For the purposes of the disclosure, the rebound edge is a narrow, projecting area on the barrier element, particularly on the force-dissipation element, which, upon impact of a vehicle or object, exerts a large force on the vehicle or object. This large force is generated because the kinetic energy is at least partially transferred to the vehicle or object as a counterforce. Due to the small surface area of ​​this rebound edge, a large force acts upon it, and significant damage can be caused to the vehicle or object impacting the rebound edge. The rebound edge can have a straight, curved, or toothed shape and preferably extends across the entire width of the force-dissipation element. The force-dissipation element with the rebound edge advantageously acts as a catching device for an impacting vehicle.The optimal height of the rebound edge can also ensure that the force dissipation element pushes the vehicle upwards and that the rebound edge also acts on the underside of the vehicle, potentially causing significant damage.

[0037] In accordance with the invention, rib elements are plate-shaped reinforcing elements that can be an integral part of a force-dissipating element and thus of a barrier element. Rib elements increase its stability against deformation. The orientation of the rib elements is preferably such that the surface of the rib element forms an angle of less than 30°, preferably less than 15°, and most preferably less than 5° with the direction of travel.

[0038] An object is plate-shaped within the meaning of the invention if its thickness is significantly smaller in relation to its other two dimensions, length and width, in particular in a ratio of 1: at least 20.

[0039] The spacing of the rib elements is the horizontal distance between the centers of two adjacent rib elements, measured along the width of the barrier element, i.e., perpendicular to the direction of travel R. The spacing is preferably chosen to ensure optimal force distribution and stability.

[0040] The base is the lower part of the barrier element, which rests at least partially on the ground and bears the main load. The base can be designed as a continuous surface or as a segmented element and serves to connect it to the ground. Preferably, the base is designed such that the rear section of the base, in the direction of travel, is spaced away from the ground and inclined upwards when erected. This allows the barrier element to be tilted onto this rear, spaced-away section.

[0041] In the context of the invention, section-by-section driving means that at least one section is suitable for driving on.

[0042] The force-dissipating element is arranged at the rear end of the upper surface of the base, which, according to the invention, is also the case if at least half of the base is already located in front of the force-dissipating element. This arrangement advantageously ensures that the vehicle at least partially drives onto the base, thereby transferring a large portion of its weight to the barrier element and the entire mobile vehicle safety barrier.

[0043] In the sense of the disclosure, a parallel alignment of the plate plane to the vehicle direction also includes deviations from parallelism if the included angle is a maximum of 30°, preferably a maximum of 20°, particularly preferably a maximum of 10° or a maximum of 5°.

[0044] The assembled state is, in accordance with the invention, when the mobile vehicle safety barrier is set up in such a way that a vehicle traveling in the direction of travel R can be blocked, with the underside of the base resting on the ground and the plane of the underside of the base running parallel to or resting on the ground. Weight

[0045] According to one possible embodiment, the barrier element has a mass of at least 250 kg, preferably at least 300 kg. The connecting unit preferably has a mass of at least 20 kg, possibly at least 40 kg. The entire vehicle safety barrier preferably has a mass of at least 500 kg, more preferably at least 650 kg, and more preferably at least 700 kg. Tooth-like projections and / or bulges

[0046] According to an advantageous embodiment of the mobile vehicle safety barrier, several tooth-like projections and / or protrusions are arranged at the end of the base facing away from the oncoming vehicle. The tooth-like projections and / or protrusions are arranged and designed such that, when the barrier element tips over due to an impact from a vehicle traveling in the direction of travel R, the tooth-like projections or the sections arranged between the protrusions penetrate the ground and anchor it in the ground.

[0047] Tooth-like projections are regularly or irregularly arranged ridges or depressions. These can be located at the rear end of the base or on the rebound edge. Tooth-like projections or bulges can advantageously increase the stopping power. The shape, size, and arrangement of the projections can vary. For example, the teeth of an excavator can be used.

[0048] The tooth-like projections and / or bulges are preferably located in the lower part of the base. This allows them to efficiently penetrate and dig into the ground upon impact, absorbing a large portion of the kinetic energy.

[0049] According to one possible embodiment, the distance between the adjacent tooth-like projections is 8 to 15 cm. The projections can each have a maximum width of 8 to 15 cm.

[0050] According to an advantageous embodiment, the length of the tooth-like projections or the depth of the indentations is at least 5 cm, preferably at least 10 cm.

[0051] According to one embodiment, the tooth-like projections are individual, elongated tooth elements that are detachably or permanently connected to the rest of the barrier element. Preferably, the tooth elements are screwed or welded to the remaining base. According to an advantageous embodiment, the tooth elements are made of hardened steel. This makes them advantageously hard and able to withstand high forces. Scratching and bending are thus prevented. Shape of the force dissipation element

[0052] According to one embodiment, the force dissipation element is designed and arranged on the top of the base in such a way that it tapers vertically in a plane parallel to the direction of travel from the top of the base towards the rebound edge.

[0053] In the context of the present disclosure, this means that the force-dissipating element becomes progressively narrower in a direction pointing away from the top of the base, i.e., upwards in the assembled state. In other words, the force-dissipating element becomes progressively narrower from the rebound edge to the connection area with the base. This advantageously ensures good force dissipation and stability. According to the invention, the progressive narrowing in the direction of the rebound edge can also be slightly modified, for example, by means of bulges. Such a modification is a maximum of 10 cm, preferably a maximum of 3 cm.

[0054] The force dissipation element is preferably inclined, at least in sections, deviating from a completely vertical orientation and facing away from the direction of travel. This allows for more efficient force dissipation. Due to this inclination, the force dissipation element with its rebound edge also advantageously acts as a catching device for an impacting vehicle. Bounce edge and rib elements

[0055] The rebound edge is preferably arranged on a rebound plate, wherein this rebound plate has a thickness of at least 8 mm, preferably at least 10 mm, preferably a thickness in a range of 8 mm to 15 mm, particularly preferably in a range of 10 mm to 13 mm.

[0056] The rib elements are preferably wider in the area adjacent to the base and then taper towards the top. This ensures good stability and efficient force distribution.

[0057] The end face of the rib elements, which points against the direction of travel, can run along an arc-like or step-like structure.

[0058] The rebound edge thus protrudes advantageously against the direction of travel, and in the event of a vehicle impact, a large force acts on this narrow area of ​​the rebound edge, resulting in high pressure and maximum damage to the vehicle.

[0059] According to one possible embodiment, the barrier element features a preferably vertically oriented plate element above the rib elements. This plate element can have a thickness of 2 cm to 10 cm and a length and width of at least 40 cm each. Advantageously, this plate element can be used for decorative purposes, such as an advertising panel. Furthermore, the plate element increases the height of the force-dissipation element, thus providing an additional impact surface.

[0060] The rebound edge may have protrusions or teeth, or it may not have protrusions or teeth. Connection unit

[0061] Optionally, the connecting unit has an elongated shape. The connecting unit is preferably designed as a steel beam.

[0062] The connecting units are optionally designed elongated along a longitudinal axis, with the longitudinal axis being arranged perpendicular to the direction of travel.

[0063] According to a preferred embodiment of the mobile vehicle safety barrier, it has at least two connecting units. The barrier elements are rigidly and preferably detachably connected to each other by means of the two connecting units.

[0064] According to an optional embodiment, the barrier elements are rigidly connected to each other by means of a connecting unit, wherein the connecting unit is designed and arranged such that it is connected to each of the two barrier elements at at least two positions. This creates a rigid connection between the barrier elements, which prevents the two barrier elements from twisting relative to each other.

[0065] The connecting unit or units are therefore preferably designed and arranged on the barrier elements in such a way that a twisting of the barrier elements relative to each other is essentially prevented.

[0066] The connecting unit is preferably located in the lower area of ​​the mobile vehicle safety barrier and is preferably designed and arranged such that, when assembled or erected, no part of the connecting unit is higher than 50 cm, preferably no higher than 25 cm, and particularly preferably a maximum of 15 cm, above the ground. This allows the mobile vehicle safety barrier to be driven over advantageously in this area as well, so that the vehicle's weight effectively reinforces the mobile vehicle safety barrier.

[0067] Optionally, the connecting unit has a plate-shaped cover above it. This makes it easier for pedestrians to cross this area. The plate-shaped cover can also be made up of multiple parts, for example, three plate-shaped cover elements. base

[0068] According to a preferred embodiment, the base and the projecting force-dissipation element are permanently connected to each other, with the rib elements also being permanently connected to the remaining section of the force-dissipation element and / or to the base. Advantageously, this makes the barrier element very stable and enables efficient force dissipation.

[0069] In the context of this revelation, "insoluble" means that it can only be separated by destroying each other.

[0070] The underside of the base can have or be formed from several parallel, plate-shaped underside rib elements. These underside rib elements are preferably aligned in the plane of the rib elements, i.e., parallel to the direction of travel. Thus, a vehicle approaching the barrier element in the direction of travel R encounters the end faces of the underside rib elements, which advantageously enables efficient force dissipation.

[0071] The mobile vehicle safety barrier preferably has jagged ground engagement elements, preferably in the form of tooth-like elements, on the underside of the underside rib elements.

[0072] This can advantageously improve the stopping effect, as the ground engagement elements are pressed into the ground by the weight of the vehicle driving onto them, thus advantageously increasing the friction between the ground and the barrier element.

[0073] The base is preferably designed such that, when the underside rests on the ground, the underside is not completely flush with the ground, but at least within a continuous gap of 0.1 m. 2The barrier element is positioned at a distance from the ground. This distance is preferably located at the rear end in the direction of travel. This allows the barrier element, or the two barrier elements, or the entire mobile vehicle safety barrier to tilt in the event of a collision, thereby transferring some of the vehicle's kinetic energy into the ground. Preferably, the mobile vehicle safety barrier has this distance in the rear area of ​​the barrier element, and the tooth-like projections and / or protrusions are located at the rear end. Thus, the tooth-like projections and / or protrusions do not rest on the ground. Advantageously, a vehicle impact generates a tilting motion, and the vehicle's kinetic energy causes the tooth-like projections or protrusions to dig into the ground.

[0074] According to an advantageous embodiment, the underside of the base lies in a plane U, with the plate-shaped rib elements arranged in planes E1i. The planes E1i are arranged perpendicular to plane U and parallel to the direction of travel R. This is an advantageous arrangement for efficient force dissipation.

[0075] Preferably, the mobile vehicle safety barrier is designed as a modular barrier, in which the barrier element is designed such that the connecting unit can be detachably attached to both sides of the barrier element. This allows more than two barrier elements to be connected using multiple connecting units. The modular design allows for adjustment of the barrier width as needed and ensures barrier-free passage for pedestrians, wheelchair users, and strollers.

[0076] Conceptually, the invention comprises a barrier element and a mobile vehicle safety barrier, which includes two barrier elements. The barrier element has a base in its lower section, which has an underside for at least partial contact with the ground and an upper surface suitable for driving over, at least partial contact. Furthermore, the barrier element has a force-dissipation element in its rear section (in the direction of travel), which is rigidly and permanently connected to the base. The force-dissipation element has a rebound edge oriented against the direction of travel and arranged at a height of 40 cm to 200 cm above the ground. Advantageously, the small surface area of ​​this rebound edge allows it to cause significant damage to a vehicle that collides with it. The force-dissipation element also has at least three rib elements aligned in a plane parallel to the direction of travel.This allows for efficient force distribution. For transporting and positioning the barrier element, as well as the entire vehicle safety barrier, a transport aid arm for a pallet truck can be attached to the base. Lifting arm mounting elements are provided on the base for this purpose. The barrier element can also be equipped with at least one temporarily attachable wheel, whereby the lifting arm and wheel can be removed or deactivated once the barrier is erected. The vehicle safety barrier also features a connecting unit that creates a rigid, detachable, and rotationally secure connection between two barrier elements. This connecting unit is a structural element that mechanically joins the barrier elements, ensuring a stable and rigid connection.This connection prevents the barrier elements from twisting relative to each other and reliably absorbs the loads that occur.

[0077] One advantage of the product is that the mobile vehicle safety barrier offers a high level of protection even under high impact loads and efficiently dissipates impact energy. The design allows for quick and manual assembly without heavy equipment, ensuring flexible and cost-effective deployment. The combination of base, force dissipation element, and connecting unit achieves a high stopping power, disabling the attacking vehicle and increasing the safety of people and infrastructure.

[0078] For the realization of the invention, it is also advantageous to combine the aforementioned inventive configurations, embodiments and features of the claims in an appropriate arrangement. Examples of implementation

[0079] Further details, features, and advantages of embodiments of the invention will become apparent from the following description of exemplary embodiments with reference to the accompanying drawings. The exemplary embodiments are intended to describe the invention without limiting it. In particular, elements of the exemplary embodiments described below can be combined with elements of other exemplary embodiments disclosed herein. The drawings show: Fig. 1: A schematic representation of a mobile vehicle safety barrier in a side view. Fig. 2: A schematic representation of a mobile vehicle safety barrier in a view taken obliquely from behind. Fig. 3: A schematic representation of a mobile vehicle safety barrier in a view taken obliquely from below.

[0080] The direction of travel R serves as a reference direction for describing the position of the individual components of the barrier element. Regardless of the actual assembly state, the direction of travel R is used to clearly define, for example, the "front" and "rear" areas, the orientation of edges, or the arrangement of connecting units.

[0081] In Fig. 1 is a mobile vehicle safety barrier 1 designed to block a vehicle traveling in the direction of travel R, comprising two barrier elements 2 and two connecting units 3 for connecting the barrier elements 2. The connecting units 3 are connected to each barrier element 2 in such a way that a rotationally secure, rigid connection between the barrier elements 2 is ensured.

[0082] The connecting units 3, shown with dashed lines, are located in the lower area of ​​the mobile vehicle safety barrier 1 and are completely covered by a plate-shaped cover 11, which extends over the entire width of the connecting units 3, i.e., over the entire area formed between the two barrier elements 2. The plate-shaped cover 11 can be made of one or more parts and ensures a flat, drivable surface in the area of ​​the connecting units 3, minimizing tripping hazards for pedestrians.

[0083] Each barrier element 2 has a base 4, which serves as a supporting foundation and has a bottom surface 9 for at least partial contact with the ground, as well as a top surface 10. The bottom surface 9 is not completely flush with the ground, but is raised at least over a continuous gap 19 of 0.1 m. 2arranged at a distance from the ground. This distance area 19 is preferably arranged at the rear end of the base in the direction of travel R.

[0084] The upper surface 10 is designed to rise in the front area in the direction of travel R in the manner of a ramp, in order to facilitate driving onto it by the front tires of a vehicle and to effectively transfer the weight force of the vehicle to the mobile vehicle safety barrier 1.

[0085] A force-dissipation element 5 is arranged at the rear end of the base 4 in the direction of travel R. The force-dissipation element 5 extends vertically upwards from the top surface 10 of the base 4 and is provided with several rib elements 7. The rib elements 7 are plate-shaped, parallel to each other, and aligned in a plane parallel to the direction of travel R. This arrangement of the rib elements 7 ensures efficient dissipation of the forces occurring during a vehicle impact into the structure of the mobile vehicle safety barrier 1 and into the ground.

[0086] The force-dissipation element 5 has a rebound edge 6 at its upper end, which is oriented horizontally and perpendicular to the direction of travel R. The rebound edge 6 is positioned so that it generates a high local force upon impact by a vehicle and achieves an effective stopping effect. Above the rib elements 7, as in this embodiment, a plate element 8 can be arranged, which is vertically oriented and can be used as an additional impact surface and as an advertising panel. The plate element 8 increases the overall height of the force-dissipation element 5 and can contribute to further strengthening the stopping effect.

[0087] Fig. Figure 2 shows an embodiment of the mobile vehicle safety barrier 1 viewed obliquely from the front, i.e., opposite the direction of travel R, consisting of two barrier elements 2 rigidly connected to each other via a connecting unit arranged below the plate-shaped cover 11. The direction of travel R is indicated as the reference direction for the orientation of the components. Each barrier element 2 includes a base 4 designed to be driven over section by at least one front tire of a vehicle. The base 4 has a bottom surface 9 for resting on the ground and a top surface 10, the top surface 10 being rigidly connected to the force-dissipation element 5 in its rear region.

[0088] The force dissipation element 5 extends vertically upwards from the top 10 of the base 4 and tapers towards the rebound edge 6. The rebound edge 6 is oriented horizontally and perpendicular to the direction of travel R and projects in the opposite direction of travel R. The rebound edge 6 is designed as a narrow, high-strength edge to generate maximum force on the vehicle upon impact and to efficiently dissipate its kinetic energy.

[0089] The force-dissipation element 5 has several, preferably at least three, plate-shaped rib elements 7, which are arranged parallel to each other and in a vertical plane parallel to the direction of travel R. The rib elements 7 are rigidly connected to the force-dissipation element 5 and serve to reinforce and efficiently dissipate forces in the event of an impact. The outer rib elements 7 are spaced apart from each other. This ensures advantageous force distribution and stability of the barrier element 2.

[0090] Several tooth-like projections 12 are arranged at the end of the base 4 facing away from the oncoming vehicle. These tooth-like projections 12 are designed as elongated, tapered tooth elements and extend from the underside 9 of the base 4 rearward and toward the ground. Upon impact of a vehicle with the mobile vehicle safety barrier 1, the tooth-like projections 12 penetrate the ground, thereby providing additional anchorage and advantageously increasing the stopping effect.

[0091] The connecting unit 3 is arranged below the cover 11. Preferably, the connecting unit 3 is positioned in the lower area of ​​the mobile vehicle safety barrier 1, such that no part of the connecting unit 3 is positioned higher than 50 cm above the ground. This allows the vehicle to drive over the area and thus contributes to effectively weighting down the barrier with the vehicle's weight.

[0092] The mobile vehicle safety barrier 1 is designed for easy setup and positioning without heavy equipment and with minimal personnel. The individual barrier elements 2 can be used as single modules or as double modules, with the connecting unit 3 allowing for flexible adjustment of the barrier width. The integration of the tooth-like projections 12 at the rear end of the base 4 and the arrangement of the rib elements 7 on the force-dissipation element 5 ensure a high stopping effect and efficient dissipation of impact energy into the ground.

[0093] The embodiment according to Fig. Figure 1 shows that the mobile vehicle safety barrier 1, through the combination of base 4, force dissipation element 5, rebound edge 6, rib elements 7, connecting unit 3, and tooth-like projections 12, constitutes a highly effective physical barrier for blocking vehicles traveling in the direction of travel R. The individual components are arranged and designed in such a way that, in combination, they ensure maximum protective effect and high mechanical stability.

[0094] Furthermore, lifting arm mounting elements 13 in the form of openings and wheel mounting elements 14 in the form of openings are arranged on the barrier element 2. A transport aid arm can be attached to the lifting arm mounting elements 13 for detachable fastening. The lifting arm mounting elements 13 can be designed as single or double openings.

[0095] Fig.Figure 3 shows an embodiment of the mobile vehicle safety barrier 1, with the direction of travel R indicated as the reference direction. The structure shown comprises two barrier elements 2, which are rigidly connected to each other by means of a connecting unit 3. The connecting units 3 are arranged as elongated elements between the barrier elements 2 and ensure a mechanically stable coupling, thus preventing the barrier elements 2 from twisting relative to each other.

[0096] Each barrier element 2 has a base 4, which, when assembled, rests on the ground with its underside 9. The base 4 is designed as a load-bearing base element and serves to allow the front tires of a vehicle to drive over it section by section. The force-dissipation element 5 is rigidly attached to the rear end R of the base 4 in the direction of travel. The force-dissipation element 5 extends upwards from the top 10 of the base 4 and forms the primary force-absorbing zone in the event of a vehicle impact.

[0097] The underside 9 of the base 4 is equipped with several underside rib elements 15, which are arranged parallel to each other in the direction of travel R. The underside rib elements 15 extend over the entire width of the barrier element 2 and are designed to enable optimal force dissipation in the event of a vehicle impact. Ground engagement elements 16 are attached to the underside rib elements 15 and rest on the ground. The ground engagement elements 16 are designed in a serrated or tooth-like manner and serve to efficiently anchor the mobile vehicle safety barrier 1 in the ground in the event of an impact. These ground engagement elements 16 direct the kinetic energy of an impacting vehicle into the ground and significantly increase the stopping power of the barrier.

[0098] The force dissipation element 5 tapers vertically from the top of the base 4 towards the rebound edge 6. The rebound edge 6 is oriented horizontally opposite to the direction of travel R and perpendicular to the direction of travel, forming the upper end of the force dissipation element 5. The rebound edge 6 is positioned such that, upon impact with a vehicle, it causes maximum force to be transferred into the vehicle, resulting in significant damage.
