Description

Die Erfindung betrifft eine Schutzausstattung zum Schutz eines Objekts gegen militärische Bedrohungen mit ballistischen Schutzelementen, die über Auflager mit einem vorgegebenen Abstand an einer Außenfläche des zu schützenden Objekts angeordnet sind.The invention relates to a protective equipment for protecting an object against military threats with ballistic protective elements, which are arranged on supports with a predetermined distance on an outer surface of the object to be protected.

Vielerlei Arten von Objekten, wie beispielsweise Container, Bunker und Fahrzeuge sind weltweit insbesondere in Krisengebieten militärischen Bedrohungen ausgesetzt. Zum Schutz solcher Objekte bzw. der in diesen Objekten befindlichen Personen werden die gefährdeten Objekte mit Schutzausstattungen versehen, die das Objekt gegen militärische Bedrohungen schützen sollen.
Weit verbreitet sind ballistische Bedrohungen, die eher punktuell auf das zu schützende Objekt einwirken, beispielsweise ballistische Geschosse. Daneben sind vor allem auch Bedrohungen infolge von Explosionen weit verbreitet. Beispielsweise entwickeln sich bei einem Sprengstoffanschlag hohe Explosionsdrücke, aus denen auch als Blast bezeichnete Gasschwaden hoher kinetischer Energie erzeugt werden, die eher flächenhaft auf das zu schützende Objekt einwirken.
Bei bekannten Schutzausstattungen werden die unterschiedlichen Bedrohungen, einerseits durch flächenhafte Blasteinwirkung und andererseits durch eher punktuell wirkende ballistische Bedrohungen, stets als voneinander isolierte Probleme betrachtet, die durch verschiedene Maßnahmen gelöst werden sollen.Many types of objects, such as containers, bunkers and vehicles, are exposed to military threats worldwide, especially in crisis areas. To protect such objects or those located in these objects Persons are provided with the endangered objects with protective equipment intended to protect the object against military threats.
Ballistic threats are widespread, which have a more selective effect on the object to be protected, for example ballistic projectiles. In addition, especially threats due to explosions are widespread. For example, in the case of an explosive attack, high explosion pressures develop, from which gas waves of high kinetic energy, also referred to as blast, are generated, which act more extensively on the object to be protected.
In the case of known protective equipment, the various threats, on the one hand due to areal blast effect and on the other hand due to rather selective ballistic threats, are always regarded as isolated problems which are to be solved by various measures.

Eine Schutzausstattung ist aus der US2380393 bekannt. Zum Schutz vor ballistischen Bedrohungen werden üblicherweise Schutzausstattungen mit ballistischen Schutzelementen, beispielsweise aus massiven Panzerstahlplatten, verwendet, die über Auflager an der Außenfläche des zu schützenden Objekts angeordnet und dort beispielsweise durch Verschrauben lösbar befestigt werden. Die Anordnung der ballistischen Schutzelemente kann anliegend an der Außenfläche des zu schützenden Objekts oder unter einem vorgegebenen Abstand gegenüber der Außenfläche erfolgen.A protective equipment is from the US2380393 known. For protection against ballistic threats protective equipment with ballistic protective elements, for example, from solid armor steel plates are usually used, which are arranged on supports on the outer surface of the object to be protected and there releasably secured, for example by screwing. The arrangement of the ballistic protective elements can be made adjacent to the outer surface of the object to be protected or at a predetermined distance from the outer surface.

Zum Schutz gegen Blasteinwirkung können diese flächigen ballistischen Schutzelemente nur wenig beitragen, da sie unter dem Einfluss eines Blastdrucks nachgeben und sich in Richtung des zu schützenden Objekts durchbiegen. Um die gefährdeten Objekte auch vor Blasteinwirkung schützen zu können, werden daher oftmals aufwändige Zusatzmaßnahmen ergriffen, beispielsweise durch eine Versteifung der Gehäusestruktur eines militärischen Fahrzeugs durch eine entsprechende Verrippung.To protect against Blasteinwirkung these flat ballistic protective elements contribute little, since they yield under the influence of a blast pressure and sag in the direction of the object to be protected. In order to protect the endangered objects also from Blasteinwirkung To be able to, therefore, often consuming additional measures are taken, for example, by stiffening the housing structure of a military vehicle by a corresponding ribbing.

Aufgabe der vorliegenden Erfindung ist es, eine Schutzausstattung anzugeben, die zugleich einen ballistischen Schutz und einen gegenüber herkömmlichen Schutzausstattungen auf konstruktiv einfache Weise verbesserten Blastschutz ermöglicht.Object of the present invention is to provide a protective equipment that allows both a ballistic protection and over conventional protective equipment in a structurally simple way blast protection.

Diese Aufgabe wird bei einer Schutzausstattung der eingangs genannten Art dadurch gelöst, dass zwischen zwei Auflagern ein Kopplungselement vorgesehen ist, über welches das Schutzelement und die Außenfläche gegeneinander druckentkoppelt und miteinander zuggekoppelt verbunden sind.This object is achieved in a protective equipment of the type mentioned above in that between two supports a coupling element is provided, via which the protective element and the outer surface against each other pressure-decoupled and coupled to each other zuggekoppelt.

Durch die Anordnung eines derartigen Kopplungselements zwischen zwei Auflagern der ballistischen Schutzelemente ergibt sich ein verbesserter Schutz des zu schützenden Objekts im Falle einer Blasteinwirkung, ohne dass hierdurch die ballistischen Schutzeigenschaften der Schutzelemente negativ beeinträchtigt würden. Es ist nicht erforderlich, das Objekt zum Schutz gegen Blasteinwirkung in konstruktiv aufwändiger Weise mit großflächig vorzusehenden Aussteifungen, beispielsweise in Form von Verrippungen, auszustatten.The arrangement of such a coupling element between two supports of the ballistic protective elements results in an improved protection of the object to be protected in the case of a blast effect, without thereby the ballistic protective properties of the protective elements would be adversely affected. It is not necessary to equip the object for protection against Blasteinwirkung in a structurally complex manner with extensible stiffeners, for example in the form of ribbing.

In vorteilhafter Ausgestaltung der Erfindung wird vorgeschlagen, dass das Schutzelement unter Blasteinwirkung im Bereich des Kopplungselements in Richtung der Außenfläche bis zur Kollision mit der Außenfläche elastisch frei durchbiegbar ist. Durch die frei durchbiegbare Anordnung des elastischen Schutzelements kann dieses sich infolge einer Blasteinwirkung elastisch in Richtung der darunter liegenden Außenfläche des zu schützenden Objekts verformen. Durch die Druckentkopplung werden dabei zunächst keine Kräfte auf die Außenfläche des zu schützenden Objekts aufgebracht, so dass sich diese zunächst nicht durchbiegt, sondern sich nur das außerhalb des zu schützenden Objekts angeordnete Schutzelement verformt.In an advantageous embodiment of the invention it is proposed that the protective element under Blasteinwirkung in the region of the coupling element in the direction of the outer surface to the collision with the outer surface is elastically freely deflectable. Due to the freely deflectable arrangement of the elastic protective element of this can deform elastically due to a Blasteinwirkung in the direction of the underlying outer surface of the object to be protected. Due to the decoupling of pressure, no forces will be present at first the outer surface of the object to be protected is applied, so that it does not initially bend, but deforms only the outside of the object to be protected arranged protective element.

In diesem Zusammenhang ist es ferner von Vorteil, wenn das Kopplungselement derart ausgestaltet ist, dass das Schutzelement beim Rückfedern über das Kopplungselement an der Außenfläche zieht, um einer Durchbiegung der Außenfläche nach Innen entgegenzuwirken. Nach erfolgter Kollision des elastisch verformten Schutzelements mit der Außenfläche bleibt dieses nach den Gesetzen der Impulsübertragung stehen, wobei es seine Energie auf die Außenfläche des zu schützenden Objekts überträgt. Die Außenfläche beginnt sich in Richtung des Innenraums des zu schützenden Objekts zu verformen. Gleichzeitig beginnt das elastisch verformte Schutzelement in einer entgegengesetzt zur Deformationsrichtung der Außenfläche gerichteten Richtung zurückzufedern. Dabei wird über die Zugkopplung des Kopplungselements eine Zugkraft auf die Außenfläche des zu schützenden Objekts aufgebracht, welche der Durchbeulung der Außenfläche des zu schützenden Objekts entgegen wirkt.In this context, it is also advantageous if the coupling element is designed such that the protective element pulls on the return spring on the coupling element on the outer surface to counteract a deflection of the outer surface to the inside. After the collision of the elastically deformed protective element with the outer surface of this remains in accordance with the laws of momentum transfer, where it transfers its energy to the outer surface of the object to be protected. The outer surface begins to deform in the direction of the interior of the object to be protected. At the same time, the elastically deformed protective element begins to spring back in a direction opposite to the direction of deformation of the outer surface. In this case, a tensile force is applied to the outer surface of the object to be protected via the coupling of the coupling element, which counteracts the Durchbulung the outer surface of the object to be protected.

Von Vorteil ist eine Ausgestaltung, bei welcher das Kopplungselement an der Außenfläche festgelegt ist und durch eine Öffnung des Schutzelements hindurchgeführt ist. Auf diese Weise ist es möglich, die Druckentkopplung und Zugkopplung des Schutzelements und der Außenfläche zu realisieren, ohne dass es hierzu erforderlich wäre, eine Öffnung in der Außenfläche des zu schützenden Objekts vorzusehen. Dies ist beispielsweise bei militärischen Fahrzeugen von Vorteil, deren Innenraum gegenüber dem Fahrzeugäußeren gasdicht abgeschlossen ist.An advantage is an embodiment in which the coupling element is fixed to the outer surface and is guided through an opening of the protective element. In this way it is possible to realize the pressure decoupling and traction coupling of the protective element and the outer surface without it being necessary to provide an opening in the outer surface of the object to be protected. This is advantageous, for example, in military vehicles, the interior of which is sealed gas-tight relative to the exterior of the vehicle.

Alternativ ist es möglich, dass das Kopplungselement an dem Schutzelement festgelegt ist und das andere Ende lose durch eine Öffnung der Außenfläche hindurch geführt ist.Alternatively, it is possible that the coupling element is fixed to the protective element and the other end is guided loosely through an opening of the outer surface.

In weiterer Ausgestaltung der Erfindung wird vorgeschlagen, dass ein durch die Öffnung hindurchgeführtes Ende des Kopplungselements mit einem Hintergriff versehen ist. Der Hintergriff wirkt beim elastischen Rückfedern des Schutzelements als eine Art Mitnehmer, über welchen die Zugkraft auf die Außenfläche des zu schützenden Objekts aufgebracht wird. Vorteilhaft ist der Hintergriff von flächiger Geometrie und weist einen größeren Durchmesser als die Öffnung auf. Zur Vermeidung ballistischer Schwachstellen deckt der Mitnehmer die Öffnung vorzugsweise vollflächig ab.In a further embodiment of the invention it is proposed that a guided through the opening end of the coupling element is provided with a rear handle. The rear grip acts on the elastic springback of the protective element as a kind of driver, via which the tensile force is applied to the outer surface of the object to be protected. Advantageously, the rear grip of planar geometry and has a larger diameter than the opening. In order to avoid ballistic weak points, the driver preferably covers the opening over the whole area.

Eine Weiterbildung der Erfindung sieht vor, dass der Hintergriff über ein Dämpfungselement gegenüber dem Schutzelement oder der Außenfläche abgestützt ist. Das Vorsehen eines Dämpfungselements bietet den Vorteil, dass ruckartige Überbelastungen auf das Kopplungselement, die zu einem Abreißen führen könnten, abgedämpft werden. Als Dämpfungselemente können beispielsweise Dämpfungselemente aus Elastomeren, Kunststoffen oder Drahtgeflechten verwendet werden. Auch besteht die Möglichkeit, die Dämpfungselemente aus Beulelementen aufzubauen, die vorzugsweise von einem oder mehreren stehenden Metallringen oder Metallspiralen gebildet werden. Die Beulelemente können derart dimensioniert sein, dass sie erst bei Überschreiten einer zulässigen Höchstzugspannung am Kopplungselement nachgeben.A development of the invention provides that the rear grip is supported via a damping element with respect to the protective element or the outer surface. The provision of a damping element has the advantage that jerky overloads on the coupling element, which could lead to a tearing, are damped. As damping elements, for example, damping elements made of elastomers, plastics or wire mesh can be used. It is also possible to construct the damping elements from Beulelementen, which are preferably formed by one or more stationary metal rings or metal spirals. The buckling elements can be dimensioned such that they yield only when an admissible maximum tensile stress on the coupling element is exceeded.

Eine weitere Ausgestaltung der Erfindung sieht vor, dass ein Ende des Kopplungselements von einer Gewindehülse gebildet wird, in welche ein das andere Ende tragender Schraubbolzen eingeschraubt ist, wodurch sich eine einfache Möglichkeit zur Montage des Kopplungselements ergibt.A further embodiment of the invention provides that one end of the coupling element is formed by a threaded sleeve, in which a bolt carrying the other end is screwed, resulting in a simple way to mount the coupling element.

Von Vorteil ist ferner eine Ausgestaltung, nach welcher der Durchmesser der Gewindehülse kleiner ist, als der Durchmesser der Öffnung. Auf diese Weise kann die Gewindehülse bei der Verformung des Schutzelements in Richtung der Außenfläche in die Öffnung eintreten. Kollisionen mit dem Schutzelement und damit eine vorzeitige Übertragung von Druckkräften auf die Außenfläche werden vermieden.Another advantage is an embodiment, according to which the diameter of the threaded sleeve is smaller than the diameter of the opening. In this way, the threaded sleeve can occur in the deformation of the protective element in the direction of the outer surface in the opening. Collisions with the protective element and thus premature transmission of compressive forces on the outer surface are avoided.

Weiterhin wird vorgeschlagen, dass die Auflager in den Randbereichen des Schutzelements angeordnet sind, wodurch sich eine lange Biegestrecke ergibt.Furthermore, it is proposed that the supports are arranged in the edge regions of the protective element, resulting in a long bending distance.

Vorteilhaft sind die Auflager im Bereich von Steifigkeitssprüngen des zu schützenden Objekts angeordnet. Derartige Steifigkeitssprünge des zu schützenden Objekts können beispielsweise im Bereich von Zwischenwänden oder an die Innenseite der Außenfläche angeschweißten Strukturen vorhanden sein. Durch das Vorsehen der Auflager in diesen Bereichen werden Durchbiegungen im Bereich der Auflager, wie diese infolge von Blasteinwirkungen auftreten können, auf ein Minimum reduziert.Advantageously, the supports are arranged in the region of stiffness jumps of the object to be protected. Such stiffness jumps of the object to be protected may be present, for example, in the region of partitions or structures welded to the inside of the outer surface. By providing the supports in these areas, deflections in the area of the supports, as they can occur as a result of blowing effects, are reduced to a minimum.

Die schematisch gehaltene Fig. 1 zeigt eine Seite eines zu schützenden Objekts 1, bei welchem es sich um ein militärisches Fahrzeug handelt. Die vorliegende Erfindung ist jedoch nicht auf militärische Fahrzeuge beschränkt, sondern kann bei vielerlei Arten von Objekten zum Einsatz kommen, beispielsweise bei Bunkern, Schiffen, Containern und dergleichen.The schematically held Fig. 1 shows a side of an object 1 to be protected, which is a military vehicle. However, the present invention is not limited to military vehicles, but can be applied to many types of objects, such as bunkers, ships, containers, and the like.

Das zu schützende Objekt 1 weist ein als Fahrzeugwanne gestaltetes Gehäuse 8 auf, das zu Vermeidung von Durchbeulungen infolge von Blasteinwirkungen B in gewissen Bereichen versteift ausgebildet ist, beispielsweise in seinen Eckbereichen. In den Eckbereichen des Gehäuses 1 ergeben sich Steifigkeitssprünge, die unter Blasteinwirkung B kaum nachgeben.The object 1 to be protected has a designed as a vehicle pan housing 8, which is designed to avoid bulging due to Blasteinwirkungen B in certain areas stiffened, for example in its corner areas. In the corner regions of the housing 1, there are stiffness jumps which barely give way under the effect of blast B.

Anders verhält es sich in den mittleren Bereichen der Außenflächen des Gehäuses 8, beispielsweise der Außenfläche 5. Im Falle einer Blasteinwirkung B in Richtung einer großen Außenfläche 5 des Gehäuses 8 kann es aufgrund der erheblichen Drücke zu Durchbeulungen D der jeweiligen Außenfläche 5 in den Innenraum des Objekts 1 kommen. Durch diese Durchbeulungen D kann beispielsweise die sich im Inneren des Gehäuses 8 befindende Besatzung des militärischen Fahrzeugs erheblichen Schaden nehmen.The situation is different in the central regions of the outer surfaces of the housing 8, for example the outer surface 5. In the case of a Blasteinwirkung B in the direction of a large outer surface 5 of the housing 8, it may due to the significant pressures to Durchbulungen D of the respective outer surface 5 in the interior of the Object 1 come. By means of these bulges D, for example, the crew of the military vehicle located inside the housing 8 can be seriously damaged.

Um derartige Durchbeulungen D zu minimieren ist die erfindungsgemäße Schutzausstattung mit einem Kopplungselement 6 versehen, was nachfolgend anhand der im Seitenbereich des Objekts 1 angeordneten Seitenfläche 5 beschrieben wird. Die vorliegende Erfindung ist jedoch nicht auf Seitenwände beschränkt, sondern eignet sich auch zur Verwendung im Bereich von Dächern oder beispielsweise als Unterbodenschutz für militärische Fahrzeuge.In order to minimize such bulging D, the protective equipment according to the invention is provided with a coupling element 6, which is described below with reference to the side surface 5 arranged in the side region of the object 1 becomes. However, the present invention is not limited to sidewalls, but is also suitable for use in the area of roofs or for example as underbody protection for military vehicles.

Wie die Darstellung in Fig. 1 erkennen lässt, weist die Schutzausstattung ein ballistisches Schutzelement 2 auf. Das ballistische Schutzelement 2 ist als Schutzplatte ausgebildet und bildet die äußere Kontur des Objekts 1. Das Schutzelement 2 besteht aus einem metallischen Material, beispielsweise aus Panzerstahl, Titan oder ähnlichen Materialien.Like the illustration in Fig. 1 can recognize, the protective equipment on a ballistic protection element 2. The ballistic protective element 2 is designed as a protective plate and forms the outer contour of the object 1. The protective element 2 consists of a metallic material, for example armored steel, titanium or similar materials.

Das Schutzelement 2 ist an einer gegenüber der Außenfläche 5 um einen Abstand A beabstandeten Position über zwei Auflager 3, 4 festgelegt. Zwischen der Außenfläche 5 und dem Schutzelement 2 sind die Auflager 3, 4 vorgesehen, die eine Art Abstandshalter bilden, wodurch zwischen den Auflagern 3, 4 ein Verformungsraum 9 entsteht. Vorzugsweise liegt der Abstand A und damit die Höhe des Verformungsraums 9 in einem Bereich von 10 bis 50 mm. Beim Ausführungsbeispiel sind die Auflager 3, 4 in zwei gegenüberliegenden Randbereichen des plattenförmigen Schutzelements 2 angeordnet. Auch ist es möglich, dass insgesamt vier Auflager 3, 4 im Bereich der Kanten des Schutzelements 2 vorgesehen sind, die einen rahmenförmigen Abstandshalter bilden.The protective element 2 is fixed at a position spaced apart from the outer surface 5 by a distance A via two supports 3, 4. Between the outer surface 5 and the protective element 2, the supports 3, 4 are provided, which form a kind of spacer, whereby between the supports 3, 4, a deformation space 9 is formed. Preferably, the distance A and thus the height of the deformation space 9 is in a range of 10 to 50 mm. In the exemplary embodiment, the supports 3, 4 are arranged in two opposite edge regions of the plate-shaped protective element 2. It is also possible that a total of four supports 3, 4 are provided in the region of the edges of the protective element 2, which form a frame-shaped spacer.

Die Auflager 3, 4 können als an die Außenkontur des zu schützenden Objekts angepasste metallische Schienen, beispielsweise aus Aluminium-Stranggussprofilen ausgebildet sein. Im Bereich der Auflager 3, 4 liegt das Schutzelement 2 druckfest an der Außenfläche 5 des Objekts 1 an. Gemäß der Ausführung in Fig. 3 ist das Auflager 4 von im Wesentlichen rechteckförmigem Querschnitt, d. h. sowohl die dem Schutzelement 2 zugewandte, wie auch die der Außenfläche 5 zugewandte Seite des Auflagers 4 sind von ebener Geometrie. Anders verhält es sich mit dem im oberen Bereich des zu schützenden Objektes vorgesehenen Auflager 3. Bei diesem ist die dem Schutzelement 2 zugewandte Seite 3.1 von im Wesentlichen ebener Geometrie, wohingegen die der Außenfläche 5 zugewandte Seite 3.2 an eine dort vorgesehene Krümmung der Außenfläche 5 angepasst ist, vgl. auch die Darstellung in Fig. 4. Eine derartige Anpassung der Seiten 3.1, 3.2 des Auflagers 3 erlaubt eine druckfeste Abstützung zwischen dem Schutzelement 2 und der Außenfläche 5. Zur Befestigung des Schutzelements 2 an der Außenfläche 5 weist das Auflager 3 mehrere über dessen Länge verteilt angeordnete Halteösen 3.3 auf. Diese sind von laschenartiger Geometrie und weisen jeweils eine Öffnung 3.4 auf, durch welche ein Kopplungselement 6 hindurchgeführt ist. Die in diesem Bereich vorgesehenen Kopplungselemente 6 dienen hauptsächlich zum Festlegen des Schutzelementes 2 an der Außenfläche 5, tragen jedoch im Gegensatz zu dem im Mittelbereich zwischen den Auflagern 3, 4 vorgesehenen Kopplungselementen 6 aufgrund der in diesem Bereich deutlich geringeren Durchbiegung des Schutzelements 2 nicht wesentlich zur Verbesserung des Blastschutzes bei.The supports 3, 4 may be formed as adapted to the outer contour of the object to be protected metallic rails, for example, made of aluminum extruded profiles. In the area of the supports 3, 4, the protective element 2 is pressure-tight against the outer surface 5 of the object 1. According to the execution in Fig. 3 is the support 4 of a substantially rectangular cross-section, ie, both the protective element 2 facing, as well as the outer surface 5 facing side of the support 4 are of planar geometry. The situation is different with that in the upper part of the object to be protected 3. In this, the protective element 2 facing side 3.1 of substantially planar geometry, whereas the outer surface 5 facing side 3.2 is adapted to a provided there curvature of the outer surface 5, see. also the representation in Fig. 4 , Such an adaptation of the sides 3.1, 3.2 of the support 3 allows a pressure-resistant support between the protective element 2 and the outer surface 5. For attachment of the protective element 2 on the outer surface 5, the support 3 has a plurality of distributed over its length arranged eyelets 3.3. These are of lug-like geometry and each have an opening 3.4, through which a coupling element 6 is passed. The coupling elements 6 provided in this area serve primarily for fixing the protective element 2 to the outer surface 5, but in contrast to the coupling elements 6 provided in the central region between the supports 3, 4 do not contribute significantly due to the significantly lower deflection of the protective element 2 in this region Improvement of the blast protection at.

Die Außenfläche 5 weist im Bereich der Auflager 3, 4 einen Steifigkeitssprung gegenüber der übrigen Fläche 5 auf, da in diesen Bereichen weitere Abschnitte des Gehäuses 8 gegenüber der Außenfläche 5 abgewinkelt verlaufen. Auch können diese Bereiche gehäuseinnenseitig mit Versteifungen beispielsweise in Form von Rippen versehen sein. Diese Bereiche geben infolge einer aus beispielsweise einer Minendetonation resultierenden Blasteinwirkung B nur wenig nach, d. h. die Durchbeulung D der Außenfläche 5 ist in diesen Bereichen gering.The outer surface 5 has a stiffness jump in the region of the supports 3, 4 with respect to the remaining surface 5, since in these regions further sections of the housing 8 extend angled relative to the outer surface 5. These areas can be provided inside the housing with stiffeners, for example in the form of ribs. These areas yield only slightly as a result of a blowing effect B resulting, for example, from a mine detonation, i. E. H. the Durchbulung D the outer surface 5 is low in these areas.

Wie in Fig. 1 weiter zu erkennen ist, ist im Bereich zwischen zwei Auflagern 3, 4 ein Kopplungselement 6 vorgesehen, dessen Einzelheiten nachfolgend unter Zuhilfenahme der vergrößerten Ansicht in Fig. 2 beschrieben werden.As in Fig. 1 can be seen further, in the area between two supports 3, 4, a coupling element 6 is provided, the details of which below with the aid of the enlarged view in Fig. 2 to be discribed.

Das Kopplungselement 6 ist mittig zwischen den Auflagern 3, 4 vorgesehen. Bei längeren Flächen 5 ist es möglich, mehrere solcher Kopplungselemente 6 hintereinander anzuordnen, vgl. auch Fig. 3.The coupling element 6 is provided centrally between the supports 3, 4. For longer surfaces 5, it is possible to arrange a plurality of such coupling elements 6 one behind the other, cf. also Fig. 3 ,

Das Kopplungselement 6 ist im Bereich seines einen Endes 6.1 mit der Außenfläche 5 des Objekts 1 verbunden. Dieses Ende 6.1 ist beim Ausführungsbeispiel 1 als eine mit der Außenfläche 5 verschweißte Gewindehülse ausgebildet. In die Gewindehülse 6.1 ist ein Schraubbolzen 6.5 aus hochhartem Material eingeschraubt, der eine Öffnung 7 des Schutzelements 2 durchdringt. Das andere Ende 6.2 des Kopplungselements 6 wird von einer mit dem Schraubbolzen 6.5 einstückig verbundenen radialen Erweiterung beispielsweise in Form eines Schraubenkopfes gebildet. Ferner ist im Bereich des Endes 6.2 ein Hintergriff 6.3 vorgesehen, dessen Durchmesser größer ist als jener der Öffnung 7 des Schutzelements 2, durch welche der Schraubbolzen 6.5 hindurchgeführt ist. Der Hintergriff 6.3 deckt die Öffnung 7 zur Vermeidung ballistischer Schwachstellen vollflächig ab. Der Hintergriff 6.3 wird gebildet von einer Panzerstahlscheibe, die gegen das als Schraubkopf ausgebildete Ende 6.2 des Kopplungselements in axialer Richtung anliegt. Alternativ zu der in den Figuren dargestellten Ausführung ist es möglich, das Ende 6.2 als kegelförmigen Schraubenkopf auszubilden, der in eine korrespondierend gestaltete kegelförmige Senkung des Hintergriffs 6.3 eingreift, wodurch sich im Bereich des Kopplungselements 6 eine verringerte Bauhöhe ergibt.The coupling element 6 is connected in the region of its one end 6.1 to the outer surface 5 of the object 1. This end 6.1 is formed in the embodiment 1 as a welded to the outer surface 5 threaded sleeve. In the threaded sleeve 6.1, a screw bolt 6.5 is screwed from high-hardness material, which penetrates an opening 7 of the protective element 2. The other end 6.2 of the coupling element 6 is formed by a one-piece with the bolt 6.5 radial expansion, for example in the form of a screw head. Furthermore, a rear grip 6.3 is provided in the region of the end 6.2, whose diameter is greater than that of the opening 7 of the protective element 2, through which the bolt 6.5 is passed. The rear grip 6.3 covers the opening 7 to avoid ballistic weaknesses over the entire surface. The rear handle 6.3 is formed by an armored steel disc, which rests against the trained as a screw head end 6.2 of the coupling element in the axial direction. As an alternative to the embodiment shown in the figures, it is possible to form the end 6.2 as a conical screw head, which engages in a correspondingly designed conical depression of the rear handle 6.3, resulting in a reduced overall height in the region of the coupling element 6.

Zwischen dem Hintergriff 6.3 und dem Schutzelement 2 ist ein Dämpfungselement 6.4 vorgesehen. Dieses Dämpfungselement 6.4 kann beispielsweise aus einem Kunststoff oder Elastomermaterial bestehen. Auch ist es denkbar, dieses als Beulelement aus metallischen Elementen auszubilden.Between the rear handle 6.3 and the protective element 2, a damping element 6.4 is provided. This damping element 6.4 may for example consist of a plastic or elastomeric material. It is also conceivable to form this as Beulelement of metallic elements.

Die erfindungsgemäße Schutzausstattung lässt sich auf einfache Weise montieren und mit wenig Aufwand auch nachträglich bei bereits vorhandenen Schutzausstattungen als Nachrüstlösung realisieren. Hierzu wird zunächst das Ende 6.1 des Kopplungselements 6 an der entsprechenden Positionen der Außenfläche 5 angeordnet. Anschließend wird das Schutzelement 2 über die Auflager 3, 4 an dem zu schützenden Objekt 1 befestigt, wobei die Öffnung 7 und das Ende 6.1 miteinander fluchten. Schließlich wird der Schraubbolzen 6.5 von außen her in das Ende 6.1 eingeschraubt und über diesen der Hintergriff 6.3 und das Dämpfungselement 6.4 gegen die äußere Fläche des Schutzelements 2 gespannt.The protective equipment according to the invention can be mounted in a simple manner and can be retrofitted with little effort even with existing protective equipment as a retrofit solution. For this purpose, the end 6.1 of the coupling element 6 is first arranged at the corresponding positions of the outer surface 5. Subsequently, the protective element 2 is fixed on the supports 3, 4 on the object to be protected 1, wherein the opening 7 and the end 6.1 are aligned. Finally, the screw bolt 6.5 is screwed from the outside into the end 6.1 and stretched over this the rear handle 6.3 and the damping element 6.4 against the outer surface of the protective element 2.

Die Funktionsweise der Schutzausstattung bzw. die bei Einwirkung eines Blasts B ablaufenden Vorgänge werden nachfolgend anhand sowohl der Darstellung in Fig. 1 als auch der Darstellung in Fig. 2 erläutert werden.The mode of operation of the protective equipment or the processes occurring when a blast B acts are described below on the basis of both the illustration in FIG Fig. 1 as well as the representation in Fig. 2 be explained.

In einer ersten Phase wirken aufgrund des Blastdrucks B extrem hohe Flächenkräfte auf das ballistische Schutzelement 2. Die Ränder des Schutzelements 2 leiten diese Kräfte über die Auflager 3, 4 an das Gehäuse 8 des Objekts weiter. In diesen Bereichen kommt es zu keiner nennenswerten Verformung des Gehäuses 8, da die Auflager 3, 4 im Bereich von Steifigkeitssprüngen des Gehäuses 8 angeordnet sind.In a first phase, extremely high surface forces act on the ballistic protective element 2 due to the blast pressure B. The edges of the protective element 2 transmit these forces via the supports 3, 4 to the housing 8 of the object. In these areas, there is no significant deformation of the housing 8, since the supports 3, 4 are arranged in the range of stiffness jumps of the housing 8.

Im mittleren Bereich des Schutzelements 2, d. h. jenem Bereich, in welchem sich das Kopplungselement 6 befindet, ist dieses in Richtung der Außenfläche 5 des Gehäuses 8 nicht abgestützt und beginnt sich infolge der Blasteinwirkung innerhalb des Verformungsraums 9 in Richtung der Außenfläche 5 elastisch zu verformen. Dabei werden aufgrund der Druckentkopplung zunächst keine Kräfte auf die Außenfläche 5 des Gehäuses 8 übertragen. Der über den Schraubbolzen 6.5 gegen die Außenseite des Schutzelements 2 verspannte Hintergriff 6.3 wie auch das Dämpfungselement 6.4 heben von der durchgebogenen Fläche des Schutzelements 2 ab. Bei hinreichend großer Verformung schlägt das Schutzelement 2 dann im Bereich seiner Öffnung 7, die zu diesem Zwecke einen größeren Durchmesser als die als Butzen ausgebildete Gewindehülse 6.1 aufweist, an der Außenfläche 5 des Gehäuses 8 an.In the middle region of the protective element 2, ie that region in which the coupling element 6 is located, this is not supported in the direction of the outer surface 5 of the housing 8 and begins to elastically deform in the direction of the outer surface 5 due to the Blasteinwirkung within the deformation space 9. Initially no forces are transmitted to the outer surface 5 of the housing 8 due to the pressure decoupling. The over the bolt 6.5 against the outside of the protective element 2 braced rear handle 6.3 as well as the damping element 6.4 lift from the bent surface of the protective element 2 from. With sufficiently great deformation, the protective element 2 then strikes the outer surface 5 of the housing 8 in the region of its opening 7, which for this purpose has a larger diameter than the threaded sleeve 6.1 formed as a slug.

Nach den Gesetzen der Impulsübertragung wird durch diesen Aufschlag die Gehäusewand und mit dieser auch deren Außenfläche 5 nach Fahrzeuginnen beschleunigt bzw. verformt, wobei die Außenfläche 6.5 das Kopplungselement 6 über dessen Ende 6.1 mitnimmt. Es ergibt sich eine Durchbeulung D.According to the laws of momentum transmission, the casing wall and with it also its outer surface 5 are accelerated or deformed towards the vehicle interior by this impact, the outer surface 6.5 entraining the coupling element 6 via its end 6.1. This results in a Durchbulung D.

Während sich die Gehäusewand und mit dieser die Außenfläche 5 nach Innen verformt und die Durchbeulung D größer wird, beginnt das elastisch verformte Schutzelement 2 quasi gleichzeitig in seine Ausgangslage zurückzufedern. Diese Rückfederbewegung ist entgegen der Bewegung der sich durchbeulenden Außenfläche 5 gerichtet.While the housing wall and with this the outer surface 5 deformed inwards and the bulge D becomes larger, the elastically deformed protective element 2 begins to spring back into its starting position quasi simultaneously. This spring-back movement is directed against the movement of the bulging outer surface 5.

Durch die Zugkopplung über das Kopplungselement 6 wird dabei eine Zugkraft auf die sich entgegengesetzt bewegende Außenfläche 5 ausgeübt, die der Durchbeulung der Außenfläche 5 entgegen wirkt. Die Zugkopplung wird erreicht über den Hintergriff 6.3, der als eine Art Mitnehmer für das sich rückverformende Schutzelement 2 dient. Überbelastungen des Schraubbolzens 6.5 werden durch eine Stauchung des Dämpfungselements 6.4 vermieden.By the traction coupling via the coupling element 6 while a tensile force is exerted on the oppositely moving outer surface 5, which counteracts the Durchbulung the outer surface 5. The traction coupling is achieved via the rear grip 6.3, which serves as a kind of driver for the recoil protective element 2. Overloading of the bolt 6.5 are avoided by a compression of the damping element 6.4.

Mit Hilfe der vorliegenden Schutzausstattung können ballistische Schutzelemente mit in den Btastschutz einbezogen werden. Es ergibt sich eine doppelte Funktionalität der die ballistischen Schutzelemente, die den Btastschutz wirkungsvoll unterstützen. Es ergeben sich Durchbeulungen, die sonst nur mit aufwändigen Versteifungen durch das Vorsehen großflächiger Verrippungen möglich wären.With the help of the present protective equipment, ballistic protective elements can be included in the load protection. This results in a dual functionality of the ballistic protection elements that support the Btastschutz effective. It results in Durchbulungen, which otherwise only with elaborate stiffening by the provision of large-scale ribbing would be possible.
