Abstract

The invention concerns a security fence shaped so as to limit the possibilities of its being crossed and having the economic advantages in that its production cost is reduced. That aim is also achieved in the event that the security fencing is used in combination with monitoring and detecting systems. Its design, at least partially, in the form of a sliding fence-gate (a) with burglar-proof rail precludes all attempt to cross it using hands, feet or means providing them with gripping support. There is no grip for hands and feet and it is impossible to cross it by climbing or by using the hands to hang on to it. In the extraordinary event the sliding barrier should be crossed (1) by use of other means, such as ladders or human pyramids, the ridge protection located at the sliding fence-gate top end nevertheless efficiently prevents the crossing of the security fence. The latter to a very large extent prevents unlawful crossing of the limits of protected areas, such as institutions enforcing judgements, private medical installations, military reserves, research centres, and also ensure the protection of stadiums, public buildings and similar security-related installations.

Security fence

Technical field

The invention relates to a security fence, in particular for high security areas. Such security fences are intended to largely prevent the unauthorized overcoming of the boundaries of protected objects in the event of break-ins or outbreaks.

They are used in particular to secure high-security areas, such as prisons, closed medical facilities, military areas, research and development areas, animal husbandry facilities, but also at sports facilities, airports and similar security-related facilities. Such security fences often consist of openwork material, such as wire mesh, expanded metal, grids, lattice mats, bars, slats or the like, which is usually held by fence posts and attached to them. The lattice-shaped material can be web-like "from the roll", whereby it is divided into sections by the fence panels, as well as individual fence panels, each extending from one fence post to the next and attached to both.

State of the art

From DE 32 45 857 C2 a fence is known, consisting of fence posts and frameless expanded metal mats which overlap in the area of the fence posts and are connected to one another while being connected to the fence posts, with the expanded metal mats lying flat against one another in the area of the fence posts U-shaped mounting bracket or the like are connected to the fence support and have an essentially parallel bend line in the upper edge region and the fence supports end below the upper edge of the expanded metal mats. In particular, the latter feature is intended to increase the resilience under the weight of a person of this fence made of expanded metal mats in the upper region and thus to ensure good climbing protection. A disadvantage of this, however, is that the expanded metal mats have openings up to their upper edge, which offer possibilities for the intervention of hands or fingers or feet or aids providing support for hands and feet. As a result, attempts to climb may not have to remain unsuccessful.

Another security fence for delimiting the playing fields of sports arenas is known from DE 41 05 862 AI. This security fence consists of dimensionally stable lattice panels, which are composed of vertical bars and horizontal bars made of spot-welded wire material.

It comprises a lower part of the fence surface which is inclined from the bottom upwards and away from the audience area, from the upper edge of which an upper part of the fence surface which slopes obliquely upwards from the audience area. This is intended to increase the size of the upper part of the fence area and thus the overhang with the same projection of the upper edge of the safety fence against the spectator area, which should make climbing over it more difficult. The disadvantage of this security fence, however, is that between the horizontal bars of the dimensionally stable lattice panels of both parts of the fence, there are possibilities of intervention for fingers, feet or these supporting aids, which make climbing, or at least dangling, and overcoming the security fence appear possible. In many cases it seems desirable to combine the security fence with alarm monitoring devices. Such monitoring monitors are used, in particular, for the constant monitoring of the security fence and the fastest possible display of attempts to overcome it. Basically, it can be combined with all common monitoring systems. Electrical or electronic monitoring systems with sensors operating according to different physical principles are preferably used. For example, Sound detectors, sensor cables, infrared detectors, microwave sensors, capacitive sensors or video sensors. All of these monitoring systems have deficiencies with regard to the undesired triggering of a false alarm and the necessary complex maintenance during the operating period.

The sensors are more or less unprotected and exposed to the weather, which can at least lead to premature corrosion and aging-related functional restrictions. Effects from animals or unauthorized persons can cause damage as well as function delays or malfunctions.

Presentation of the invention

The invention is therefore based on the problem of designing the security fence in such a way that the possibility of overcoming it is further restricted and there are cost advantages due to little outlay. A low manufacturing and maintenance effort should also be achieved if the security fence is used in combination with alarm monitoring systems.

The object is achieved with the security fence specified in claim 1. Its, at least in part, design as a smooth, breakthrough slip barrier excludes any penetration with hands, feet or aids to support them. Hands and feet therefore have no hold. Overcoming has been made impossible by climbing and hanging. If, by way of exception, the area of the sliding barrier has been overcome using other aids, such as ladders or pyramids, the crown protection at the upper end of the sliding barrier effectively prevents the safety fence from being overcome. At least partially, only the upper area of the security fence or the individual fence fields, the fence is designed as a sliding barrier. If the lower area of the security fence is made of cheaper material, this results in full security of the required security Standards, cost advantages when installing the security fence.

The height of the sliding barrier is 30% to 50%, preferably 40%, of the vertical height of the security fence. With a currently required height of security fences of 5000 to 6000 mm, the totality of the requirements is met, which results in particular from the particularities of the different groups of people to be excluded or protected, their physical properties and vitality.

According to another embodiment of the invention, the vertical extension of the sliding barrier should correspond to the gripping size of a person of average size of the group of people to be taken into account, plus a safety allowance. Use is made of the knowledge that the grip dimension corresponds approximately to the human body size.

The safety allowance is preferably 16.5%, because with this value the deviations with regard to the body size of the respective group of people are mainly recorded statistically and / or differences in physical vitality are taken into account.

An advantageous embodiment of the invention provides that the vertical dimension of the sliding barrier is preferably dimensioned 2050 mm. This value is based on the current statistical average body height of the male population of 1760 mm and the mentioned safety allowance and thus corresponds to the safety requirements for the group of people with the largest average body size and the highest vitality on average. As a result of the known acceleration in the growth of adolescents, the stated value of 2050 mm is naturally subject to constant further development.

According to a favorable embodiment of the invention, the material of the sliding barrier is dimensionally stable and thus largely resistant to damage and destruction.

An advantageous embodiment of the invention can also be seen in the fact that the material of the sliding barrier is flexible. In addition to being easier to process and adapt Local conditions have the advantage that it is able to withstand attempts to destroy them to a certain extent.

For reasons of monitoring, a further favorable embodiment of the invention provides for the use of completely or partially transparent material for the sliding barriers, in particular if video technology is used for observation.

Polycarbonate has proven to be a particularly well-suited material that fulfills all requirements for the sliding barrier. For reasons of deliberately restricted privacy protection, it can also be used structured or tinted. In addition to the main safety function, the sliding barrier can also provide sound and wind protection. In addition to equipping the continuous security fence with the sliding barrier, a further advantageous embodiment of the invention provides the possibility of equipping each fence field or section individually with one. This expresses the great adaptability of the security fence according to the invention to the given local conditions, which is expressed not only in the new building, but also in the retrofitting of the majority of the already existing fences in the interest of increasing their security standards. Further embodiments of the invention, which can be found in the subclaims, provide expedient connecting elements for connecting the fence fields or sections to one another and / or to the fence columns, which preclude support on them by means of hands, feet or aids. They therefore functionally support the sliding barriers. According to another embodiment of the invention, the crown protection of the upper edge of the sliding barrier is designed as a rotatable roller which, in the theoretical case of overcoming the sliding barrier, can slide off the attacking hand or a corresponding aid as an additional safety measure. This additional security measure to prevent the security fence from being overcome can be connected to a suitable alarm device which indicates tampering. The same applies to the further additional safety measures, which can be found in the subclaims, in the form of the crown protection with the appropriate fastening elements, such as tensioning wires, loosely wound wire rolls and wire anchor anti-slip devices. The selection of the most effective security measure depends on the security requirements, in particular the groups of people to be protected, and local conditions. Since the safety fence, which is fully formed in the area of the sliding barrier and without any opening or breakthrough, does not offer any support for hands and feet, overcoming is largely prevented by using hands and feet for climbing or climbing. The further configuration of the upper edge of the sliding barrier as a crown protection corresponds to an additional securing measure which counteracts, in particular, differently than attempts to overcome the security fence by reaching over or climbing over it. A particular advantage of the security fence according to the invention can be seen in the fact that it can be erected with little effort and also retrofitted to practically all installed security fences to increase security. Due to the box-shaped design of the fence fields, the material and assembly costs are increased in comparison to a simple, extensive planking of the fence field, but since the signaling system in the boxes is protected, its maintenance causes such little effort that the total effort is reduced. In addition, there is the advantage that a double anti-skid device is more difficult to penetrate and the function of the message monitoring system is not or hardly impaired by undesirable weather and environmental influences, and this also makes it difficult to overcome the fence. A reduced number of false reports not only reduces the effort involved in checking, but also increases the security standard because the willingness of the surveillance personnel to recognize an actual attempt to overcome them increases becomes.

An advantageous embodiment of the invention is also to be seen in the fact that the front and rear boundaries of the boxes of the fields are formed by the breakthrough sliding barriers. The double function of this construction element is cost-saving.

On the other hand, the protective function of the boxes can be increased if they are also closed at the top. According to a further embodiment, the crown protection of the security fence can advantageously be used for this at the same time.

The advantages mentioned can also be achieved to an even greater extent if the boxes are also delimited at the bottom, preferably by using the foundation of the security fence.

It is by no means necessary to hermetically seal the boxes in order to achieve the major part of the advantages mentioned. In the arrangement according to the invention of a signal monitoring system, which is designed as a pressure detector that responds to pressure drop within an adjustable interval, an air flow is generated in the boxes and a constant, defined excess pressure is maintained. This has the advantage, on the one hand, of an increased sensitivity of the detector, which responds to a drop in pressure to a relatively small extent, and, on the other hand, can counteract overheating within the boxes caused by intensive solar radiation in exposed locations.

According to a further embodiment of the invention, the leaks in the boxes or ventilation openings specifically provided in them can be used to maintain the pressure level produced and set by the pressure generator and to generate the desired ventilation flow. An embodiment of the invention is also to be seen in the fact that, as a signaling monitoring system in the boxes in the fields of the security fence, cables are routed back and forth between deflecting rollers at defined intervals between adjacent fence posts. The tension spring-loaded ropes are wrapped with a large wrap angle on shafts of chip attached rope pulleys. Even if the cables are only slightly deflected, the waves of the voltage generators are rotated and a voltage that can be measured and displayed in an alarm center is generated. This is a particularly simple and inexpensive design of the message monitoring system. The use of low-stretch material for the ropes has the advantage that even small changes in length are sufficient to produce a usable tension value. A further advantageous embodiment of the invention consists in the fact that the signaling monitoring system consists of at least one fence-field-related electrical circuit, the signal transmitters of which break during an attempt to overcome pressure or pull and trigger an alarm signal in the alarm center. This message monitoring system requires little effort. It is easy to assemble and requires little maintenance with a long service life. In addition, the fence-field-related display of any attempts to overcome them in the alarm center allows them to be located and initiated quickly, so that verification and, if necessary, search measures can be initiated. Due to the fact that false reports are largely excluded as a result of the protected arrangement of the reporting surveillance system, the security personnel is additionally sensitized because they attach greater importance to incoming reports.

In Fig. 1, the execution of the kinked, entire security fence is shown as a full-surface sliding barrier 1. The possibility of bending even after the second side is indicated by dashed lines. It will be important if both sides of the security fence are security-relevant.

2 shows the top view of sliding barriers 1 made of zigzag-shaped profiled material and their arrangement on the fence posts 2. The embodiment of the angled sliding barrier 1 shown in FIG. 3 is a continuation of the fence field 3 in the lower part of the security fence. Other angular possibilities are suggested using dashed lines. 4, the fence field 3 is covered with the sliding barrier 1 in its upper region. This has at least the perpendicular extension of the gripping dimension 5 and an additional safety allowance. The gripping dimension 5, straight or angled, corresponds to the length in the opposite direction straight arms and hands of a person of average height of the relevant, to be preserved or excluded group of people. Experience shows that the grip size 5 corresponds to the body size of the comparative person.

5, if the arm 7 of the fence field 3 is suitably dimensioned, an arrangement of the sliding barrier 1 on the former is also possible. This is a particularly simple, security-effective and cost-effective solution and can also be retrofitted to existing security fences.

The arrangement of a second boom is indicated by dashed lines in FIG. 5. If the dimension of the boom 7 is not sufficient, then the sliding barrier 1 must also be designed angled in order to reach and exceed the gripping dimension 5, as shown in FIG. 6. This variant is shown again in FIG. 7 with a safety fence with two arms 7 which is effective on both sides. Analogously, the solution according to FIG. 8 is to be assessed with sliding barriers 1 arranged on both sides. In this case, the entire fence field 3 is equipped accordingly. The possibility of expanding this solution with these safety fences to arms 7 which are effective on both sides can be seen from FIG. 9. If two fence panels 3 meet at right angles, which occurs frequently in practice and may represent a weak point in terms of security technology, the sliding barrier 1 can be made as corner element 8 in the adjacent area of the angled fence panels 3 of the security fence in the manner shown in FIG. 10 - to lead.

The safety requirements fulfilled by the sliding barrier 1 in suitable dimensions can only be effectively met, however, if the fastening and connecting elements used for supporting hands, feet or aids do not offer any possibility. FIG. 11 shows an appropriate fastening element 10 with an inner cover 9 on the safety-relevant side of the safety fence. The illustration according to FIG. 12 corresponds to another connection of the sliding barrier 1 to the fence field 3 by means of a rivet 21 in the overlap area 20. The fastening elements 10 with inner covers 9 for attaching the sliding barriers 1 to the fence columns 2 and to the building 11 are shown in FIG. The fence panels 3 can also be locked in the same way. Fence columns 2 with brackets 7 can also be used by means of such fastening elements 10 for connection to the, in this case angled, sliding barrier 1, as shown in FIG. 14.

The covering of the overlap area of the two sliding barriers 1 by means of the metal strip 14 in the case of the joint connection to the fence column 2 by the fastening element 13 according to FIG. 15 and the connection of the two sliding barriers 1 to the overlap area 15 according to FIG. 16 are sufficient for the safety requirements Fastener requirements. Further options for the design of fastening elements can be seen from FIGS. 17 to 20, such as triangles with stud bolts 12 according to FIGS. 17 and 18, trapezoidal fastening elements 22 according to FIG. 19 and expansion bolts 18 corresponding to FIG. 20.

At the upper edge of the sliding barrier 1, a crown protection 19 is provided as an additional safety measure for the more theoretical case of overcoming the sliding barrier 1.

21, the crown protection 19 consists of rollers 23 which are attached to the two angled sliding barriers 1. With appropriate dimensioning of their diameter of 30 to 50 mm, they make it difficult to reach around the upper edge and let hand or tools slide off. The solution according to FIG. 22 is effective in the same way, as shown in FIG. 23, the crown protection 19 can also consist of tension wires 17 held by spacers 28, which are designed as tear-off threads. Both of the above configurations of the crown protection 19 can also be combined with electronic or other signaling devices and thus the security fence can be effectively monitored. The design of the crown protection 19 as anchoring anchor slide Fuse 24 can be seen in the illustrations in FIGS. 24 to 26.

Further configurations are possible. Thus, the anchor anchor slide protection 19 can also consist of a repelling wire roll made of barbed wire or blade wire with loosely lying turns. The throwing anchor slide protection 19 acts equally against the embracing of the upper edge of the sliding barrier 1 and the fence field 3 by hand. Suitable fastening elements are encompassing clamps 25 which establish the connection by means of rivets 26. The tubular throwing anchor anti-slip devices 24 can also be slit longitudinally downwards and placed on the fence fields 3 with the sliding barriers 1, as can be seen from FIG. 26. For this purpose you can also have integrated flanges for a better connection.

In the case of the solution according to FIG. 26, the fastening possibility consists of a countersunk screw 27.

FIG. 27 shows a detail of a security fence, approximately the width of a fence field 3, between two neighboring fence posts 2. The fence columns 2 are held by the continuous foundation 29 made of concrete. 28, the sliding barriers 1 made of breakthrough material, in particular made of polycarbonate, are fastened on both sides of the fence columns 2 and at the same time form the front and rear boundaries of the box 4. The sliding barriers 1 are interrupted by bolts 40. But they can also be made in one piece. The crown protection 19 is arranged at the upper edge of the sliding barriers 1. The crown protection 19 also forms the upper limit of the box 4, while the foundation 29 acts as its lower limit. The limits of the box 4 do not need to hermetically seal it. The compressed air generated by a compressor (not shown) and stored in a pressure container (also not shown) is fed to the box 4 via the compressed air ring line 31 and the line 38 branching from it in relation to the field. Inside the box 4 with leakage due to the leakage between its limits, the compressed air supplied flows in the direction of the Crown protection 19 designed as a tube with ventilation opening 33 arranged at the end thereof. At the same time, it serves to dissipate heat, which could have arisen to an increased extent, for example, as a result of intensive solar radiation. The pressure interval of the air in box 4 is adjustable. However, if a pressure drop occurs within the system essentially formed by the box 4, for example as a result of air escaping from a hole broken into the sliding barrier 1, then the pressure detector, for example designed as a measuring wheel 32 of a wind turbine generator, responds. Switching membranes or electronic pressure monitoring systems can also be used.

The monitoring result is forwarded to an alarm center via a data bus, which can run within the boxes 4 over the entire length of the security fence, and is displayed there in relation to the respective fence field 3. This makes it easier to quickly locate the attempt to overcome it and thus to take countermeasures in good time. The arrangement of the message monitoring system 6 inside the box 4 protects it from weather and environmental influences and prevents the triggering of a false alarm. This increases security. Premature corrosion does not occur, so that the operational readiness of the message monitoring system 6 is maintained over a long period of time. There is also a considerable cost advantage in this as well as in the saving of maintenance work.

FIGS. 29 and 30 show sections of another security fence, in the box 4 of which an electromechanical monitoring system 6 is arranged. The boundaries of the box 4 are formed in the same way as in the exemplary embodiment described above according to FIGS. 27 and 28.

In the area of the fence field 3 shown, a rope 35 is guided at defined intervals back and forth over deflection rollers 34 between the neighboring fence posts 2. The deflection rollers 34 are arranged behind screens 39 which block the view. On the one hand, the rope 35 is fastened to the fence column 2, on the other hand, it is tensioned adjustable by a tension spring 37. The rope 35 wraps several times around a rope pulley 41, which is attached to the shaft of a voltage generator 36. This detail can be seen in Fig. 31. If the cable 35 is deflected or severed, this leads to a rotation of the shaft of the voltage generator 36, as a result of which a voltage is generated.

This is evaluated by an electronic module (not shown) and fed via a data bus to the alarm center, also not shown, where the display is based on the fence field 3 concerned and enables the incident to be located.

The use of low-stretch material, for example braided plastic tendon, for the rope 35 increases the sensitivity of the signaling monitoring system 6, which, as a result of its positioning within the boxes 4, extends over the entire length of the security fence and is protected from weather and environmental influences. The number of incorrect reports can be considerably minimized with this less complex arrangement. An electrical message monitoring system 6 can be seen from FIGS. 32 and 33. It basically consists of circuits 44; 45. The number of circuits 44; 45 can be varied. These circuits 44; 45 are connected to the alarm center. The signal generator 42 within the circuits 44; 45 are arranged at a defined distance from one another between the adjacent fence posts 2.

Protected from view, they are held behind brackets 39 by brackets 43. The brackets 43 consist of insulating rubber or a similar material and are able to accommodate temperature-related changes in length of the signal transmitter 42. The signal transmitters 42 are in a suitable manner conductive with the circuits 44; 45 connected, for example soldered or by plug connections. The material of the strand or rod-shaped signal transmitters 42 is fragile and at least partially electrically conductive. As a result of pressure or tension in an attempt to overcome the signal transmitter 42 break, so that the circuit 44; 45 is interrupted and the voltage interruption evaluated by an electronic module, not shown, is displayed in the alarm center, also not shown, based on the location of the fence field 3 concerned. The signal generator 42 can consist of a tubular, electrically conductive ceramic material. It is also possible to provide a non-conductive material in whole or in part with a conductive metal coating or foil strip, which is also severed if the signal transmitter 42 breaks, for example due to its small thickness. It is also conceivable to equip the signal transmitter 42 with predetermined breaking points.
