Description

[0001] The invention relates to a mobile fence with a holder having an opening formed on the top side of the holder, and with at least one fence post which can be inserted into the opening and to which at least one fence element can be fastened.

[0002] Furthermore, the invention relates to a holder for a fence, comprising a holder body.

[0003] Furthermore, the invention relates to a fence post.

[0004] The invention also relates to a door element with a first fence post for receiving in a first holder and a second fence post for receiving in a second holder, wherein the first fence post and the second fence post are connected via a fence element.

[0005] Such fences, brackets, and fence posts are known from the state of the art, for example from construction sites in the form of site fences or from public events in the form of barriers. These fences are intended to have the property of being quick to erect and dismantle and, on the other hand, to close off or restrict an area to be enclosed or demarcated, such as, but not limited to, an event space, a construction site, or a solar park, or to protect it from unauthorized access. The disadvantages of the fences known from the state of the art are in particular the lack of security against unauthorized access and the lack of any possibility of monitoring the fence and its components. For example, with the known site fences, it is easy to lift the fence post out of the hole in the bracket, thereby opening the fence and gaining access.The individual construction fence elements are secured at best by clamps, which are also easy to open. At the same time, barriers, such as those often used at public events, are not tip-proof. Aside from the fact that the areas cordoned off in this way are not adequately secured, it can pose a serious danger to the people standing at the barriers should a mass panic break out. Another disadvantage is the limited flexibility of conventional fences. For example, construction fences and barriers are only available in certain dimensions. The height of the fences is predetermined and cannot be adjusted to individual situations.

[0006] The object of the invention is therefore to create a mobile fence, a holder, a fence post and a door element of the type mentioned at the beginning, which on the one hand can be quickly erected and dismantled, offer reliable monitoring and on the other hand have a high level of security and flexibility.

[0007] The object of the invention with regard to the mobile fence is achieved in that the fence post has a crossbar at one end facing the holder, and wherein the opening extends from one of the side surfaces of the holder in the direction of the opposite side surface over at least twice the width of the crossbar and wherein the crossbar can be received laterally in the opening.

[0008] These features mean that the fence posts can be inserted laterally into the openings on the side surfaces. When viewed in relation to an entire fence, not each fence post is inserted into a single hole on top of the bracket, but two fence posts are inserted one behind the other into the opening. This ensures that the fence posts secure each other, while the crosspieces at the end of the fence post provide additional stability for the fence posts in the bracket, thus making the fence more stable. It is particularly advantageous if the fence element is selected from the list of chain link fence, lattice fence, electric fence, transparent surface, opaque surface, Plexiglas, bullet-proof glass, guardrail, barbed wire fence, or concrete fence.The opening extends from one of the side surfaces across at least twice the width of the crossbar toward the opposite side. This has the advantage that the crossbars are only accessible from one side of the mount—ideally the side facing the area to be secured—and are thus protected against unauthorized access.

[0009] Furthermore, a sensor unit is arranged on or in the holder and / or on or in the fence post and / or on or in the fence element. The sensor unit serves to detect at least one item of status information and / or at least one item of environmental information of the mobile fence. The term "status information" within the meaning of this application can be understood as information about possible damage and / or open areas and / or tampering with the holder and / or the fence post and / or the fence element. In particular - but not restrictively - the status information can be understood to mean that the sensor unit can detect whether the fence has been impaired and / or tampered with by external influences to such an extent that it can no longer perform its actual function or can only do so to a limited extent.

[0010] For the purposes of this application, the term "environmental information" can be understood as information about the immediate surroundings of the mobile fence and / or its components (mounting bracket and / or fence post and / or fence element). In particular, the at least one piece of environmental information can be a condition of the surrounding terrain and / or events in the vicinity of the mobile fence. In this case, the term "surroundings" can be understood as an area from several tens of meters to hundreds of meters from the fence. In particular, the term "surroundings" can be understood as the area delimited by the mobile fence and to be protected.

[0011] For example - but not limited to - the sensor unit can detect whether a flood, a landslide or a mass panic has occurred or is occurring in the vicinity of the mobile fence in order to be able to take appropriate countermeasures (such as making an emergency call) if necessary.

[0012] In one embodiment, the sensor unit comprises at least one of the following sensors: - Vibration sensor; and / or - motion sensor; and / or - Piezo sensor; and / or - Optical sensor; and / or - Temperature sensor.

[0013] The use of a sensor unit that has at least one of the sensors mentioned above offers the advantage that different safety-relevant events can be reliably detected and evaluated.

[0014] A vibration sensor, for example, detects subtle shocks or vibrations that typically occur when the fence is subjected to mechanical stress—e.g., when someone attempts to climb, shake, cut, or move the fence. The major advantage of this sensor is its early warning of physical tampering. Furthermore, it can be configured to distinguish between normal environmental influences (e.g., wind) and security-relevant vibrations. This provides effective protection against sabotage and theft.

[0015] A motion sensor can detect movement in the vicinity of the fence – using infrared, ultrasonic, or microwave technology, for example. The advantage is that approaches to the fence can be detected even before contact is made. This enables proactive monitoring, as potential intruders are detected before they actually attempt to break in. This sensor is ideal for perimeter protection at night or in remote construction areas.

[0016] Piezo sensors respond to pressure or deformation, generating electrical signals. These sensors are particularly well-suited for detecting direct contact with the fence element itself, such as when someone climbs on it, leans on it, or attempts to damage it. Because piezo sensors are highly sensitive to mechanical stress, they offer a precise way to monitor structural changes or impacts—even under adverse weather conditions.

[0017] Optical sensors—for example, in the form of cameras, light barriers, or LIDAR systems—provide visual information or detect interruptions in a light signal. Their advantage lies in the ability to objectively verify an incident through imagery or by detecting a specific approach or crossing of a monitored area. Furthermore, modern optical sensors can be combined with a neural network to distinguish, for example, human movements from animals or vehicles.

[0018] A temperature sensor measures the ambient temperature and can detect unusual thermal changes, such as those caused by fire development, heat exposure from machinery, power sources, or deliberate arson. The advantage lies in the ability to detect fire hazards early on—a significant aspect on construction sites where flammable materials or ignition sources may be present. The sensor can also contribute to monitoring climatic conditions, for example, to assess working conditions or the impact on stored materials.

[0019] The combination of these different sensor types creates an intelligent, multi-dimensional security system that not only reacts to a single event, but also reliably detects a wide variety of scenarios – from the slight shaking of the fence to the sudden heat buildup from a fire. The mobile fence thus becomes an active security element that can react to threats in real time and initiate appropriate countermeasures (e.g., triggering an alarm, notifying personnel, recording data).

[0020] Alternatively or additionally, a data transmission line can be arranged on or in the holder and / or on or in the fence post and / or on or in the fence element in order to be able to use the mobile fence and in particular its components as a data transmission means.

[0021] Within the scope of the invention, it is further provided that the cross-section of the opening on the side surface is preferably T-shaped or L-shaped. This ensures that the fence posts are optimally received in the holder and, in the case of cuboid-shaped fence posts, form a positive connection with the opening in the holder. The end of the fence post facing the holder and the cross-section of the opening on the side surface are therefore advantageously coordinated with one another. If the cross-section of the opening on the side surface is T-shaped, the fence post optimally has a T-shaped end, while the end of the fence post is optimally L-shaped if the opening in the holder is L-shaped.

[0022] Furthermore, it is advantageous that the opening extends continuously from one side of the bracket to the opposite side. This simplifies the manufacture of the bracket and allows the fence posts to be inserted into the opening from both sides, and even more than two fence posts can be inserted.

[0023] Furthermore, it is preferred that a means for securing the bracket to a subsurface be provided. This allows for further securing the bracket and thus the fence against tipping and / or unauthorized access. The means for securing the bracket can be in the form of a dowel, a ground nail, a hook, holes, or similar.

[0024] Furthermore, it is advantageous for the bracket to have a base plate and holes provided in the base plate for fastening to the ground. The base plate can be formed integrally with the bracket or, for ease of production, welded or otherwise connected to the bracket. The base plate, i.e., the larger contact surface on the ground, increases the stability of the fence, and the holes, through which dowels, pegs, or hooks can be inserted, further stabilize and secure the fence.

[0025] Within the scope of the invention, it is further provided that the bracket has a securing element for securing the crosspieces in the bracket. This serves to further secure the crosspieces in the bracket and protects the fence from unauthorized access. In a particularly simple embodiment, the securing element can be designed as a U-lock, with the crosspieces formed as hollow bodies having holes, allowing the crosspieces to either secure each other as in a U-lock or to be connected to the bracket.

[0026] In a preferred embodiment, two securing holes and / or a threaded rod are formed on at least one of the side surfaces, which is perpendicular to the surface and perpendicular to the side surfaces having the opening, wherein the securing element is U-shaped with two U-legs that can be received in the securing holes and / or in the crossbars, and a U-web with a securing element hole for receiving the threaded rod, and wherein the securing element and the threaded rod can be connected by a fastening means to secure the crossbar in the holder. This additionally fixes the crossbars in the holder, wherein it is particularly advantageous if this securing structure is formed on the inside of the fence, i.e. on the side to be protected. This makes it impossible, for example, for people standing on the outside of the fence to open the securing structure.

[0027] Furthermore, it is preferred that the fence post has a coupling section at the end facing away from the holder. It is advantageous if the coupling section has a different diameter than the diameter of the fence post. In particular, it is advantageous if the coupling section is assigned a coupling element which forms a positive connection with the coupling section for connecting a coupling section of a first fence post to a coupling section of a second fence post. This allows the height of the fence to be varied by attaching any number of fence posts one above the other. Depending on the shape of the fence post, the coupling element is formed as a cuboid or as a cylinder, the diameter of which differs from that of the coupling section. In addition, the coupling section and coupling element can be secured using screws, pins, or clamps.The securing element manufactured to secure the fence panels has the advantage of also serving as a connection / coupling lock. The coupling elements feature identically dimensioned holes and a threaded rod.

[0028] Furthermore, it is intended that the coupling section can be connected to an adapter element, and that the adapter element is selected from the list of L-piece, plate, extension pole, tripod, angle piece, or Y-piece. This allows the fence to be individually designed and adapted to requirements. The angle pieces, Y-pieces, or L-pieces make it possible to additionally bend the fence inwards or outwards, thus increasing security by making it difficult to climb over the fence. The adapter elements can also be connected to fence elements such as barbed wire rolls, electric fences, barbed wire fences, barbed wire, mesh, or similar. The attachment of the plate, in turn, allows lamps to be attached to this plate, thus illuminating the fence over a wide area.

[0029] Furthermore, it is preferred that the material for each constituent component of bracket, fence post, door element and fence element is selected from the list of concrete, reinforced concrete, recycled plastic, steel or aluminum.

[0030] Within the scope of the invention, it is further provided that, in order to form a second barrier plane, the holder has at least one second opening spaced from the first opening for fastening a fence element.

[0031] This, in turn, can increase the security of the fence by either erecting a second fence spaced apart from the first, or by installing an additional guardrail, for example, to protect the fence from breaking vehicles. The opening can also be positioned perpendicular to the first opening, and any number of additional openings can be created.

[0032] The object of the invention, relating to the holder, is achieved in that the holder body is formed by two L-pieces connected to a base plate, the free legs of which point towards each other and in that the base plate optionally has holes. This is a particularly simple design of the holder, which makes it possible to securely accommodate fence posts, whereby a groove is created between the L-piece and the base plate into which the fence posts can be inserted. Preferably, the L-piece is welded to the base plate, but other types of fastening are also conceivable. Alternatively, the holder can also be manufactured using injection molding technology or by 3D printing, so that the holder and base plate can be manufactured as a single piece or separately.Alternatively, for use with a fence post whose end has an L-shaped piece, the bracket body can also be formed by an L-shaped piece connected to a base plate and a web connected to the base plate, with the free end of the L-shaped piece pointing toward the web. The base plate, if it has holes, can be fixed to the ground. Furthermore, the advantageous embodiments mentioned in the dependent claims for the fence relating to the bracket can also be applied to the bracket itself.

[0033] According to one embodiment, a handle element is arranged or formed on at least two side flanks of the holder. The respective handle element is either formed integrally, i.e., monolithically, on the holder and / or the holder body, or alternatively, is arranged as a handle on the holder and / or the holder body, in particular, in a materially bonded manner. This allows for easy carrying and / or relocation of the holder, which can weigh several tens of kilograms when ready for use.

[0034] In a supplementary or alternative embodiment, a boundary web extending substantially orthogonally to the opening and / or the second opening is arranged in the opening and / or the second opening. The boundary web prevents a fence element inserted into the opening and / or the second opening from being pushed through and thus serves as a type of stop.

[0035] The problem concerning the fence post is solved by having one of the ends T-shaped or L-shaped and by the fence post being formed as a hollow body, cuboid or cylindrical. The T-shaped or L-shaped end stabilizes the fence post in the holder thanks to its large contact surface and also allows the fence post to be fixed within the holder. The formation of the fence post as a hollow body means that the fence posts are comparatively light and can therefore be easily transported from one place to another. The cuboid or cylindrical design enables easy and cost-effective production, whereby it is particularly preferred to give the fence post a cylindrical shape. The associated holder can accommodate both cuboid and cylindrical fence posts, and these can also be fixed to one another.A further advantage is that the type of fastening means that the fence panels can be installed both horizontally and vertically in the provided brackets. For example, with an element measuring L = 3.00 meters and H = 1.50 meters, this element can also be rotated 90° around an axis in the format L = 1.50 meters and H = 3.00 meters. The fence height can therefore be varied as desired using the same element. Likewise, for longer fence sections, sections can be created at different heights. To do this, it is necessary to attach a T- or L-shaped base of the fence post to one of the brackets at the upper end of the tube using a coupling element.

[0036] The object relating to the door element is achieved by a door element of the type mentioned at the outset in that the fence posts have a crossbar at a first end, wherein the first fence post is mounted so as to be rotatable about the crossbar and wherein the second fence post is detachably connected to the crossbar. In this context, it is particularly preferred if the fence post is cylindrical, as this makes it easy to rotate the fence post about the crossbar. The detachable connection between the fence post and the crossbar can be realized, for example, by a snap-in fit. The advantage of this embodiment of the door element is that it does not visually differ from the other fence elements with which it can be combined, so that unauthorized persons cannot distinguish one door element from another fence element.Potential weak points in the fence construction are therefore not visible to an outsider. It is particularly advantageous if a sliding surface is arranged between the crossbar and the fence post. In this context, it is particularly preferred that a locking rod is provided within the second fence post, which can be moved against the second fence post along the longitudinal axis and is detachably connected to the crossbar. In a preferred embodiment, the locking rod can be actuated from outside the fence post, for example by means of a lever. The locking rod can be lifted when the door element is opened, whereby the locking rod is released from the crossbar and the door can be opened. For the design of the gate and door systems, it is also provided to equip the actuating element with a roller at the lower end.This allows the gate to be locked, and after opening, the operating element can be pushed back down and locked into place. This operating element thus functions as a roller for easier opening and closing of the gate element. The roller is completely guided within the gate post, thus fulfilling a dual function.

[0037] In summary, the advantage of the invention is that it creates a modular system for a mobile fence that allows a fence to be erected and dismantled particularly quickly and provides particularly effective protection against unauthorized access. By designing coupling sections and the presence of various coupling and adapter elements, it is possible to easily vary the height of the fence and install additional security elements. The design of the fence post with a T-piece or L-piece arranged at the end, which in turn can be inserted into an opening formed on the side of the bracket, increases the security and stability of the fence. By additionally designing a security element on the inside of the fence, the crossbars can be further secured to one another and to the bracket.The door element allows easy access to the inside of the fence without creating any security vulnerabilities. Furthermore, the sensor unit enables monitoring of the mobile fence and its components, as well as the surrounding area.

[0039] The mobile fence according to the invention comprises any number of combinations of brackets 1, fence posts 4, fence elements 5, door elements 20, and adapter elements 19. The present invention is therefore a modular system. An opening 2 of a bracket 1 can accommodate at least two fence posts 4, each connected to a fence element 5. The fence posts 4 are formed as hollow bodies, cuboid or cylindrical. The bracket 1, in turn, can accommodate both cuboid and cylindrical fence posts 4. The fence elements 5 can be formed as wire mesh, electric fence, cross braces, panels (transparent or opaque), barbed wire, mesh, or similar. The individual elements of the mobile fence are described below:

[0040] Fig. Figure 1 shows a first embodiment of the fence post 4 according to the invention. This is formed as a hollow body, with the fence post 4 in the present embodiment being cuboid-shaped. At the end facing the holder, the fence post 4 has a crosspiece 6.

[0041] How Fig. As can be seen in Figure 1, the fence post 4 has a T-shaped end. Alternatively, the end can also be L-shaped. The crosspiece 6 is also formed as a cuboid-shaped hollow body, but can also be cylindrical if the fence post is 4-cylinder-shaped.

[0042] Fig. Figure 2 shows a second embodiment of the fence post 4 according to the invention. This has a coupling section 15 at the end facing away from the holder 1. This coupling section 15 can have the same diameter as the fence post 4, or a different diameter. Using the coupling section 15, the adapter elements 19 can be connected to the fence post 4, such as L-pieces ( Fig. 3), angle pieces ( Fig. 4), plates ( Fig. 5), extension poles, or Y-pieces can be attached to the fence post 4. This, in turn, allows for the installation of additional fence elements 5 such as barbed wire, lighting systems, etc., and / or for the fence element 5 to be directed inward or outward, making it even more difficult to climb over the fence. The adapter element 19 can be secured via a hole with a screw or a clamp.

[0043] Furthermore, as Fig. 6 shows that a coupling element 16 can also be assigned to the coupling section 15, which forms a positive connection with the coupling section 15. This allows a first fence post 17 with a first coupling section 15 and a second fence post 18 with a second coupling section 15 to be connected to each other via the coupling element 16, thus varying the height of the fence post 4 or the fence. Adapter elements 19 can also be connected to the fence post 4 using the coupling element 16.

[0044] Fig. 7 shows a first embodiment of the holder 1 according to the invention. This has an opening 3 on the top side 2, wherein the opening extends continuously from one side surface 7 to the opposite side surface 8. However, it is also sufficient if the opening 3 extends only from one side surface 7 of the holder 1 in the direction of the opposite side surface 8 over at least twice the width of the crossbar 6 of the fence post 4. The cross section of the opening 3 on the side surface 7, 8 is T-shaped or L-shaped, i.e. the cross section of the opening 3 and the end of the fence post 4 facing the holder 1 are adapted to one another. Both the holder 1 and the fence post 4 can be made of concrete, reinforced concrete, recycled plastic, steel or aluminum.The bracket 1 can be fixed to the ground using a means 9 (not shown) to further secure the mobile fence against unauthorized access or tipping. In the present embodiment, fastening using hooks or ground nails would be conceivable. Alternatively, the bracket can have holes 26 as fastening means 9, allowing the bracket to be secured with pins, screws, hooks, or the like.

[0045] Furthermore, as Fig. 8 shows - the holder has a base plate 23. On this base plate 9, holes 26 are formed as fastening means, so that the holder can be fixed to the surface using pins, screws, hooks, etc.

[0046] Fig. 9 shows a third embodiment of the holder 1, which, in addition to a first opening 3, has two further openings 21 that are perpendicular to the first opening 3. These two further openings 21 also have a T-profile and can, for example, accommodate guard rails to secure the mobile fence against being breached by a motor vehicle. Alternatively, further openings 21 can also be provided in the holder 1, which are arranged as desired but at a distance from one another. For example, a second barrier level can also be formed by erecting a second fence level at a distance from the first, without the need for an additional holder 1.

[0047] Fig. Figure 10 shows a fourth embodiment of the holder 1 according to the invention, which is formed from a base plate 23 and a holder body 22. The holder body in turn comprises two L-pieces 24 connected to the base plate 23, the free legs 25 of which point toward each other. The base plate 23 and the L-pieces 24 thus each form a groove into which the ends of the fence posts 4 can be pushed and secured. The base plate 23 can in turn have holes 26 for fastening the holder 1 to the ground.

[0048] All features of the holders 1 of the various embodiments can be combined or exchanged.

[0049] Fig. Figure 11 shows the securing of the fence post 4 in the holder 1. It should be noted that the cross-section of the side surface 7 and the end of the fence post 4 facing the holder 1 are L-shaped. However, the securing principle is also transferable to the T-shaped embodiment: The fence post 4 is pushed through the opening 3 on the side surface 7, 8 of the holder 1 into the holder 1 and forms a positive connection with it - in the case of a cuboid-shaped fence post 4. At least one second fence post 4 can optionally also be pushed into the same opening 3 on the side surface 7.

[0050] How Fig. 12 shows, a securing element is additionally provided for securing the crosspiece 6 in the holder 1. For this purpose, a threaded rod 11 and two securing bores 12 are formed on at least one of the side surfaces, which is perpendicular to the top side 2 and perpendicular to the side surfaces 7, 8 having the opening 3. The securing element 10 is U-shaped with two U-legs, which are received in the securing bore 12 and in the hollow body of the crosspiece(s) 6, and a U-web with a securing element bore 13. The securing element 10 is pushed onto the threaded rod 11, or the securing element bore 13 receives the threaded rod 11 of the holder 1, while the U-legs of the securing element 10 are received in the securing bore 12 of the holder 1 and in the hollow body of the crosspieces 6. By means of an additional fastening means 14 - in this case a nut - the securing element 10 and the holder 1 orThe crosspieces 6 are fixed. The combination of the bracket 1 with a T- or L-shaped opening 3, which accommodates a fence post 4 with a T- or L-shaped end, and the securing element 10 secures the fence post 4 and thus the fence vertically and horizontally. It is particularly preferred if the securing element 10 is fixed to the bracket 1 on the closed-off side of the fence, i.e., on the side of the fence that is to be secured against third parties. Fig. 12 further shows a fifth embodiment of the holder 1 according to the invention, wherein the holder body 22 is formed by an L-piece 24 connected to the base plate 23 and by a web 29 connected to the base plate 23, wherein the free leg 25 of the L-piece 24 points in the direction of the web 29.

[0051] Fig. 13 and Fig. 14 show an embodiment of the door element 20 according to the invention, which comprises a first fence post 17, which is received in a first holder 1, and a second fence post 18, which is received in a second holder 1, and which are connected via a fence element 5 - in this case in the form of cross braces. The fence posts 17, 18 each have a crossbar 6 at their end facing the holder 1. The first fence post 17 is rotatably mounted about the crossbar 6 and / or the fence element 5, while the second fence post 18 is detachably connected to the crossbar 6 and / or to the fence element 5. The holder 1 and the fence posts 17, 18 have the properties described above. Within the second fence post 18, a locking rod 27 is provided which can be displaced against the second fence post 18 along the longitudinal axis and which is detachably connected to the crossbar 6 or the fence element 5.A locking seat and a sliding surface are formed between the locking rod 27 and the crosspiece 6. An actuating element is provided on the door element 20, with the aid of which the locking rod 27 can be actuated and the locking seat released. The door can then be opened. When the door is closed, the locking rod 27 re-engages the locking seat.

[0052] Fig. Figure 18 shows a fifth embodiment of the holder 1 according to the invention in a top view and a side view. The fifth embodiment of the holder 1 is characterized in that it has gripping elements 33 formed on at least two side flanks 32. The gripping elements 33 can, for example, as shown in Fig. 18, shown as gripping projections formed by a conically tapered flank structure of the side flanks 32 of the holder 1. Alternatively or additionally, the gripping elements 33 can be arranged on the holder 1, in particular in a materially bonded manner in the manner of a fixed handle.

[0053] Furthermore, according to the fifth embodiment, the holder 1 has a limiting web 34 that extends orthogonally to the opening 3 and / or the second opening 21. The limiting web 34 serves as a stop for a fence element 5 inserted into the openings 3, 21, so that it cannot be "pushed through" the respective opening 3, 21. Such an embodiment increases the stability of the mobile fence in the assembled state.

[0054] All features of the holder 1 according to the fifth embodiment can also be combined or exchanged with all features of the holders 1 of the various embodiments described above. Furthermore, as can be seen from the figures, on or in the holder 1 (see Fig. 7) and / or on or in the fence post 4 (cf. Fig. 1) and / or on or in the fence element 5 (cf. Fig. 13) a sensor unit 31 is arranged. For the sake of simplicity, the sensor unit 31 is shown only schematically as a rectangle. The sensor unit 31 serves to detect at least one item of status information and / or at least one item of environmental information of the mobile fence and can, for example—but not limited to—comprise a vibration sensor and / or a motion sensor and / or a piezo sensor and / or an optical sensor and / or a temperature sensor.
