Description

[0001] The invention relates to a driving lock according to the features of the preamble of claim 1.

[0002] Such barriers are well-known and are designed to be placed in a vehicle's path to prevent unauthorized vehicles from using the path. The barrier is designed to stop these vehicles immediately and prevent them from reaching a protected area behind the barrier.

[0003] At the same time, however, it must be ensured that the travel barrier can be moved away at short notice to clear the roadway for an authorized vehicle, for example, in an emergency, so that the protected area behind the travel barrier can be reached by this authorized vehicle (such as an ambulance or the like). Safety requirements regarding mobile travel barriers (also known as vehicle safety barriers) are standardized in DIN SPEC 91414-1. For any definitions and requirements, reference is made to DIN SPEC 91414-1, which is hereby incorporated into the application by reference.

[0004] For example, a water basin has already become known as a vehicle barrier. While it can be set up quite quickly at the site, it does not meet the requirements of DIN SPEC 91414-1. However, it takes a long time to fill the basin with water. Furthermore, this water must be readily available at the site. Another disadvantage is that in an emergency where time is limited, such a water basin can only be removed after too long a period of time to allow the authorized vehicle access to the area to be protected.

[0005] Other barriers have a base with which they are set up at the site. Once set up, they also have a rotating part that folds up and locks into place to block the roadway. This does offer a certain degree of protection against unauthorized vehicles attempting to pass through the roadway. However, the disadvantage is that the folded-up part must be very strong to ensure adequate protection against unauthorized vehicles. There is always a risk that the folded-up and locked part will simply be bent by the unauthorized vehicle, as it can only support itself at its pivot point on the base when the vehicle hits it and cannot offer any further resistance.Another disadvantage is that the raised part, several of which are arranged at a distance from one another, poses a risk of injury to people passing through this travel barrier. A major problem with this known travel barrier, and generally with other travel barriers, is that the travel barrier is often not hit with the full width of the vehicle. Instead, the vehicle only hits the travel barrier with part of its width, and the other part of its width does not hit any travel barrier, but rather the free area next to the travel barrier (so-called offset).

[0006] DE 10 2022 133 240 discloses a preferably mobile travel lock, comprising a stationary part as the first element and a rotatable part as the second element. The at least one rotatable part is operatively connected to the at least one stationary part in that both parts are mounted for rotation about a pivot point. Furthermore, the at least one stationary part has a drivable lower part. The at least one rotatable part, which can be actuated, in particular, by an unauthorized vehicle to be stopped, is arranged on the at least one stationary part. The rotatable part can be actuated by an unauthorized vehicle to be stopped. To actuate the rotatable part, the stationary part is designed such that it has a lower part drivable by an unauthorized vehicle, so that the rotatable part can be triggered by contact with the vehicle.After the vehicle has hit the ground and is activated, the rotating part rests on the ground on which the travel lock is installed.

[0007] The invention is based on the object of providing a driving lock that is simple in design and uncomplicated in handling, while at the same time being highly effective in protecting against approaching unauthorized vehicles

[0008] This problem is solved by the features of claim 1.

[0009] According to the invention, each of the two elements is U-shaped in its central region and at least two legs extend outwards from the central region. This advantageously makes it possible to quickly assemble the two elements by plugging the respective U-shaped central region of one element together with the corresponding U-shaped central region of the other element. Depending on the weight and / or size of the two elements, this can be done by people. However, since a high weight of the driving lock is desired, this plugging together is carried out mechanically, for example by a forklift truck, a crane or the like. Storage of the elements is simplified because they can be built more flatly and can therefore be stacked on top of each other when not in use.For example, several such elements can be stacked on a Euro pallet and thus very easily transported to and from their destination. Once the two elements have been assembled and assembled at their destination, they offer effective protection against approaching unauthorized vehicles and the like, stopping them in their tracks. This is achieved by the at least two legs that extend outwards from the central area. Once the two elements have been assembled, the travel lock according to the invention thus has a cross-like geometry, which causes an unauthorized vehicle that drives into the travel lock to be lifted, thereby initially dissipating kinetic energy.This effect is further increased by the fact that the vehicle loses at least partial contact with the ground as a result of this lifting by means of the driving lock, particularly in the area of ​​its drive axle, so that further propulsion and thus further movement of the vehicle is prevented.

[0010] In a further development of the invention, exactly four legs extend outward from the center of each element. In a preferred embodiment, these four legs, together with their center from which they originate, are arranged flatly in one plane. This results in a flat stacking when the elements are not needed. Furthermore, the cross-shaped geometry of the travel lock is achieved when the two elements are plugged together at the installation site.

[0011] In a further development of the invention, the two elements are designed in an approximately X-shape. This means that, for example, the four legs are each arranged at an angle of approximately 90°, preferably exactly 90°, to one another. When the two elements are plugged together, their respective areas or the legs extending from them are also arranged at an angle of approximately 90°, preferably exactly 90°, to one another, resulting in an optimal cross-shaped geometry of the driving lock. This geometry causes the driving lock to move underneath the vehicle like a cube as the vehicle continues to move, lifting it and thereby bringing it to a standstill.

[0012] In a further development of the invention, the two elements have openings in their central region that are aligned when the two elements are operatively connected. A fastening means is provided that can be inserted and secured through the aligned openings. Although it may generally be sufficient for the two elements to simply be plugged together, the use of fastening means has the advantage of increasing the stability of the travel lock and preventing the two originally plugged-together elements from separating when the vehicle collides.

[0013] As a further development of the invention, the fastening means is provided in a form of a screw and a corresponding nut. The screw and nut can be delivered to the site of use and, once the two elements have been assembled, can be inserted through the aligned openings in the center areas and secured with the corresponding nut. This effectively connects the two elements. This connection can be easily removed and stored after the travel lock has been used (especially if it is no longer needed).

[0014] In a further development of the invention, it is provided that at least one end of the first element and / or at least one end of the second element has at least one opening. With this at least one opening, in particular at the free end of a respective leg, it is possible to secure the travel lock at the site of use using suitable means, for example in the ground. Additionally or alternatively, it is possible to connect at least one opening of a travel lock (consisting of two elements) to at least one opening of another travel lock (consisting of two further elements) using suitable means, such as a chain, a steel cable, a shackle or the like.

[0015] In a further development of the invention, at least one end of the first element and / or at least one end of the second element has at least one tip configured to engage the vehicle and / or the ground at the site of use. Preferably, all ends of the first and second elements have such tips. This increases the effectiveness of stopping a vehicle that is approaching without authorization and colliding with the barrier.

[0016] In a further development of the invention, it is provided that the first element and / or the second element are made of flat metal sheets, preferably of flat metal-steel sheets, in particular of a steel material. Although the travel lock can in principle also be made of materials other than metal, the highest possible weight is important for its use and effectiveness. This can be achieved by using a metal material, whereby production from metal sheets, preferably metal-steel sheets, simplifies the production of each element, since these can be welded together in the desired shape.

[0017] In a further development of the invention, it is provided that the cavity formed by the flat metal sheets is at least partially, preferably completely, filled with a filler. If the cavity is filled with a filler, this increases the weight of the driving lock. Filling preferably takes place on site, after the two elements have been put together and, if necessary, connected with the fastening means. Care must be taken to ensure that the use of the fastening means is not hindered by the filler, and that the filler cannot escape through the openings in the middle area of ​​the two elements for the fastening elements. Possible fillers include water, sand or the like, and suitable openings and closures must be provided for filling and draining the substance.If the filling is to be permanent, it can be filled with sand (which can be removed again if necessary), with concrete (which remains permanently in the cavity) and the like.

[0018] In an alternative embodiment for increasing the weight of the travel lock, the first element and / or the second element are made of a solid metallic material, in particular a steel material, preferably cast. This further increases the weight compared to elements that are joined together from sheet metal, in particular welded together, as well as the effectiveness of the travel lock during use. At the same time, however, this requires that both elements must be handled mechanically. Alternatively or additionally, the first element and / or the second element can be made of a concrete material, in particular reinforced concrete. Either both elements are made of concrete, or one element is made of concrete and the second element is made of the steel material. An element made of concrete can be reinforced with reinforcements such as rebar, fibers, mesh, and the like.

[0019] In a further development of the invention, the two elements of the travel lock are designed identically. This simplifies storage and assembly, since, especially during assembly, there is no need to worry about which element needs to be connected to which other element. Assembly (and, of course, disassembly) is simplified by simply providing two elements and plugging them together, without having to pay attention to the geometric design of each element.

[0020] In a further development of the invention, it is provided that the driving lock is a mobile driving lock. The driving lock is preferably a mobile driving lock. Such a mobile driving lock not only complies with the DIN SPEC 91414-1 standard, but also exceeds the requirements of this standard in many respects. However, it is also possible for the driving lock to be not mobile (i.e., it can be quickly moved to its location, set up, and removed again), but rather stationary (i.e., permanently located at its location). In addition to this design, it is of course conceivable for the driving lock according to the invention to remain permanently at its location, although this is not the preferred intended use of the driving lock according to the invention.

[0021] A further development of the invention provides for multiple travel barriers to be positioned next to each other and / or one above the other. If the height and / or width of a single travel barrier is insufficient at the intended location, multiple travel barriers can be positioned next to each other and / or one above the other to optimally fill the width and / or the space at the location. In practice, it is often sufficient to position two or more travel barriers (each consisting of two elements connected together) next to each other to prevent vehicles from unauthorizedly driving onto the travel barrier.

[0022] The term "vehicles" in relation to vehicles that can drive through the travel lock according to the invention should be interpreted broadly. All powered and / or non-powered vehicles, as well as objects that, when moving, especially rolling, develop sufficiently high kinetic energy that they pose a danger to persons, are "vehicles" within the meaning of the invention, which, in principle, can drive into the travel lock.

[0023] An embodiment of a driving lock according to the invention is shown in the Fig. 1 and Fig. 2. A supplementary embodiment is shown in the Fig. 3 and Fig. 4 shown.

[0024] In Fig. 1, as far as shown in detail, a ready-to-use vehicle barrier 1 is shown, which consists of two elements 2, 3, wherein in Fig. 2 one of the two elements is shown and its details, which may or may not also apply to the other element, are described in more detail

[0025] The vehicle barrier 1 consists of two elements 2, 3 that can be plugged together, each of the two elements 2, 3 being U-shaped in its central region and having at least two legs extending outwards from the central region. The first element 2 has end regions 4, with which it can be set up, for example, on the ground at the site of use. The second element also has end regions 5. In contrast, there are also free regions 6 of the first element 2 and free regions 7 of the second element 3. In the vehicle barrier according to the embodiment according to Fig. 1, exactly four legs 10 to 13 extend outward at an angle of 90° from the central region of each element 2, 3. Furthermore, the two elements 2, 3 are joined together at an angle of 90° to one another. The arrangements, each at an angle of 90° to one another, result in the illustrated cross-shaped geometry of the travel lock 1, which is particularly effective for its application. However, it is also possible to provide the angles at which the two elements 2, 3 are joined together and / or the angles at which the at least two legs are arranged to one another in a different order of magnitude.

[0026] With a view to the Fig. 2, further details of this element, which may or may not also apply to element 3, are described below.

[0027] The central region of this element 2 has a transverse web 8 and a recess 9. Four legs 10 to 13 extend outward in a plane in an approximately U-shaped manner from this central region. The recess 9 in the central region is formed by a longitudinal web 14 and a longitudinal web 15 extending from the transverse web 8 approximately or preferably exactly at right angles. The transverse web 8, together with the longitudinal webs 14, 15, thus forms the recess 9.

[0028] In an end region of at least one leg, preferably in the end regions of all four legs 10 to 13, a plate-shaped end region, in particular designed as a plate-shaped closing element, is present in the end region 4, 6 of the first element and / or in the end region 5, 7 of the second element 3. In this end region or closing element [and / or in the free end region of each leg 10 to 13 (not shown)], at least one opening 16 is present. Suitable fastening means can be passed through this respective opening 16 in order to either fix the respective element 2, 3 to the ground and / or to connect it to elements of another travel lock 1. In addition, the end region or closing element can have at least one tip 17, preferably two tips 17 as shown, with which the travel lock 1 can grip during use in a vehicle and / or on the ground at the site of use.

[0029] Present in this embodiment, but not specifically designated with reference numerals, are openings in the center region of the two elements 2, 3, which are aligned when the two elements 2, 3 are operatively connected (plugged together). A fastening means is provided that can be inserted and secured through the aligned openings. Alternatively or additionally, the two elements 2, 3 can also be permanently connected to one another in another way at their location of use once the two elements 2, 3 have been plugged together.

[0030] In Fig. 3 is the driving lock 1 according to Fig. 1, which may contain further structural configurations. The free end 6 of the travel lock 1 according to Fig. 3 can, as in Fig. 2, which have at least one tip 17. However, it can also be omitted. Protruding from the surface of the free end 6, preferably at a right angle, is at least one further tip 18. This allows the travel lock 1 to grip onto or into the surface, for example, the ground or road surface, at the location where it is to be set up for its intended purpose. As shown in Fig. 3, there are two spaced apart tips 18 per free end 6 (or per free end 4). There may also be only one tip per free end 4, 6. Likewise, more than two tips 18 per free end 4, 6 may be arranged. Even if it is shown in the Fig. 3 and Fig. 4 shows that at least one tip 18, preferably two tips 18 spaced apart from one another, is present at each free end 4, 6, but it is not necessarily necessary for such a tip 18 to be present at each free end. However, if at least one tip 18 is present at each free end 4, 6 of the driving lock 1 (or of the respective element 2), this results in symmetry which advantageously means that it does not matter how the two elements 2, 3 are assembled to form the driving lock 1, since it is ensured in any case that the tips 18 at the free ends 4, 6 are aligned towards the ground at the installation location of the driving lock 1.

[0031] Furthermore, in the Fig. 3 and Fig. 4 shows that the drive lock 1 (according to Fig. 3) or their respective Element 2 (according to Fig. 4) has at least one eyelet 19. Preferably, the at least one eyelet 19, preferably several eyelets 19, are arranged around the area of ​​the crosspiece 8, projecting outwards. In Fig. 3 it is particularly clearly visible that the surface of the crosspiece 8 of the illustrated element 2 facing in the direction of the further (not shown) element is preferably square, and an eyelet 19 is arranged in each corner region of this square. This symmetrical arrangement of the eyelets 19 also has the advantage that the symmetrically designed elements 2 (or 3) can be combined with one another in any desired way. There is no need to observe a specific assembly sequence, a specific removal from storage of such elements, and the like. With the at least one eyelet 19, the respective element can be handled with force, for example by means of a forklift truck, a crane, or the like, particularly when the element 2, 3 is so heavy that it can no longer be handled by one or two people.

[0032] A respective eyelet 19 can be part of a steel sheet from which the element 2, 3 is assembled. However, it can also be arranged on the element 2, 3 after its manufacture or even during its manufacture, for example by welding it on (if the element is made of a steel material) or by partially casting it in (if the element is made of solid concrete).

[0033] As an alternative to the embodiment in which the respective eyelet 19 is an integral part of the element 2, 3, the respective eyelet 19 can also be designed as a separate component, which is arranged and secured to the element 2, 3 as required. For example, the eyelet 19 can be designed with a cylindrical end section, wherein the end section has a thread (in particular an external thread) which is screwed into a corresponding mating thread (in particular an internal thread) in the element 2, 3. By means of an eyelet 19 (or preferably several eyelets 19) that is (are) screwed into the element 2, 3, the respective element 2, 3 can be moved with power assistance (for example, by means of a forklift, a crane or the like) for the purpose of assembly, disassembly or its positioning at the installation site if this cannot be accomplished by one person due to its high weight.After completing the assembly or disassembly of elements 2, 3, the respective eyelet 19 is unscrewed from the element 2, 3 and stored. Alternatively, it is conceivable that after the assembly of the two associated elements 2, 3, which form the X-shaped travel lock 1, the respective eyelets 19 of the two elements 2, 3 are firmly connected to each other using appropriate connecting means (such as a steel cable, chain, or the like) so that these two elements 2, 3 can no longer be separated once they have been assembled. This is especially important in the event of an emergency.

[0034] Additionally or alternatively, the respective eyelets 19 of the two elements 2, 3 and the corresponding connecting means can be used to connect several X-shaped barriers 1, each of which consists of the two elements 2, 3, to one another in order to secure a larger width, for example, the width of a road, if this width to be secured is greater than the width of an X-shaped barrier 1 alone. This naturally also applies in the case where several X-shaped barriers 1 are set up not only next to one another, but also one above the other.

[0035] The detachable eyelets 19, in particular screwable eyelets 19, can be arranged in the same way as shown by way of example in the Fig. 3 and Fig. 4 with respect to the eyelets 19 formed integrally with the elements 2, 3.

[0036] It is noted that the two elements 2, 3, which are in Fig. 1 or Fig. 3 are preferably identical in design, but do not have to be identical. If they are identical in design, it no longer matters which section (end section or free section) of each leg is used for setting up the respective element, since all end sections of the legs are designed identically, thus significantly simplifying the setup process of the travel lock at the site.
