Abstract

The bullet trap (2) has at least one layer (20) of thermoplastic, the melting point of which is set at below 100 DEG C, if appropriate by the admixture of a softener. The thermoplastic layer can consist of plastic blocks put together in the manner of a wall. There can be arranged on the rear side of the plastic layer (20) facing away from the shooting-in side a steel rear wall (21) which serves both for increasing the safety against shooting through and as a carrier for the plastic layer (20) and a sound-proofing material layer (24) arranged on its front side. In the plastic layer (20), the bullet is braked slowly and remains largely undamaged. The plastic material can easily be separated from the bullet remains thermally and recycled. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Geschoßfangvorrichtung, bestehend aus mindestens einer Schicht mit mindestens einem Formteil aus einem Geschoßfangmaterial zum Abbremsen und/oder Aufnehmen von Geschossen, wobei das Geschoßfangmaterial aus thermoplastischem Kunststoff besteht. Ferner bezieht sich die Erfindung auf ein Verfahren zur Rückgewinnung von Formteilen für die Geschoßfangvorrichtung.The invention relates to a projectile trap consisting of at least one layer with at least one molded part made of a projectile trap material for braking and / or picking up projectiles, the projectile trapping material being made of thermoplastic material. The invention further relates to a method for recovering molded parts for the projectile trap.

Geschoßfangvorrichtungen, bei denen die Geschosse durch min­destens eine Schicht eines Geschoßfangmaterials abgebremst und aufgefangen werden sind bekannt. In vielen Fällen wird das Geschoßfangmaterial kostengünstig unter Verwendung von Alt­gummi hergestellt.Bullet trapping devices in which the projectiles are braked and caught by at least one layer of bullet trapping material are known. In many cases, the bullet trapping material is manufactured inexpensively using waste rubber.

So ist beispielsweise aus der DE 32 12 781 A1 ein Geschoßfang­material bekannt, das aus Abfallgummigranulat mit einem Kunst­harz-Bindemittel gebildet wird. Ähnlich sind in der DE 34 18 626 A1 Schichten aus Altgummigranulat und Polyurethankleber vorgesehen. Das in der DE 34 42 984 A1 verwendete Geschoßfang­material besteht aus einem elastischen Werkstoff, wie Kaut­schuk, Kautschukregenerat oder Elastomeren. Allen diesen Ge­schoßfangmaterialien, ob homogen oder heterogen, ist gemein, daß sie zumindest in Teilbereichen dauerhaft vernetzt sind. Mechanisches oder thermisches Recycling sowohl des Geschoß­fangmaterials als auch des Geschoßbleis ist daher unmöglich.DE 32 12 781 A1, for example, discloses a projectile trapping material which is formed from waste rubber granulate with a synthetic resin binder. Similarly, DE 34 18 626 A1 provides layers of waste rubber granulate and polyurethane adhesive. The bullet trapping material used in DE 34 42 984 A1 consists of an elastic material, such as rubber, regenerated rubber or elastomers. All these bullet trapping materials, whether homogeneous or heterogeneous, have in common that they are permanently networked, at least in some areas. Mechanical or thermal recycling of both the bullet trapping material and the bullet lead is therefore impossible.

Aus der DE-PS 75 836 ist demgegenüber eine thermoplastische Geschoßfangmasse bekannt, welche aus einer zähen Mischung aus Steinkohlenteer, Steinkohlenpech, Goudron, Epuree, Lehm und Sand besteht. Aus dieser Masse können die Geschosse durch Ausschmelzen entfernt werden, so daß eine vollständige Rückge­winnung sowohl des Geschoßfangmaterials als auch des Geschoß­materials möglich ist. Die Rückhaltwirkung der Masse ist je­doch so gering, daß eine große Schichtdichte nötig wird. Ein weiterer Nachteil besteht darin, daß die zähe, stets fließ­fähige Masse nur in geschlossenen Behältern verwendet werden kann, wobei die beschußseitige Wand häufig erneuert werden muß.In contrast, from DE-PS 75 836 a thermoplastic bullet trap is known, which consists of a viscous mixture of coal tar, coal pitch, Goudron, epuree, clay and sand. The projectiles can be removed from this mass by melting, so that a complete recovery of both the projectile trapping material and the projectile material is possible. However, the retention effect of the mass is so low that a high layer density is necessary. Another disadvantage is that the tough, always flowable mass can only be used in closed containers can, the wall on the bombardment side often having to be replaced.

Schließlich ist aus der DE-OS 15 78 238 eine Kugelfangmasse aus Polyisobutylen allein oder in Verbindung mit Butylkaut­schuk oder kautschukähnlichen Stoffen unter Zusatz von Füll­stoffen bekannt. Die dort beschriebene Masse ist knetbar, also weich und von veränderlicher Form. Sie kann in einem zur Be­schlußseite hin offenen Kasten untergebracht oder zum Be­schichten von Wänden etc. verwendet werden. Die Projektile können aus der Masse entfernt und diese kann wieder in Form geknetet werden. Nachteilig ist, daß die beschriebene Knetmas­se nur unter hohem Arbeitsaufwand oder mit komplizierten Knet­maschinen von den Geschossen befreit werden kann.Finally, DE-OS 15 78 238 discloses a bullet trap made of polyisobutylene alone or in combination with butyl rubber or rubber-like substances with the addition of fillers. The mass described there is kneadable, ie soft and of variable shape. It can be accommodated in a box open to the decision side or used for coating walls etc. The projectiles can be removed from the mass and this can be kneaded again in shape. The disadvantage is that the modeling clay described can only be freed from the projectiles with a lot of work or with complicated kneading machines.

Obwohl die Masse einen thermoplastischen Kunststoff enthält, ist die apparativ einfache Möglichkeit einer thermischen Tren­nung von Geschossen und Kugelfangmaterial in der DE-OS 15 78 238 nicht vorgesehen; der nach dieser Druckschrift vorzugswei­se sehr hohe Anteil an festen Füllstoffen bringt ein bis zur Zersetzungstemperatur schlechtes Fließverhalten mit sich.Although the mass contains a thermoplastic, the simple possibility of thermal separation of projectiles and bullet trap material is not provided in DE-OS 15 78 238; the proportion of solid fillers, which is preferably very high according to this publication, results in poor flow behavior up to the decomposition temperature.

Der Erfindung liegt demgegenüber die Aufgabe zugrunde, eine Geschoßfangvorrichtung bzw. eine durchschußsichere Wand zu schaffen, die das Geschoß rückprallsicher abbremst und bei der sowohl das Geschoß- als auch das Geschoßfangmaterial auf ein­fache und ökonomische Weise thermisch zurückgewonnen werden können.The invention is based on the object to provide a projectile arresting device or a bulletproof wall which brakes the projectile in a rebound-proof manner and in which both the projectile and the projectile trapping material can be thermally recovered in a simple and economical manner.

Ausgehend von einer Geschoßfangvorrichtung der eingangs ge­nannten Art, wird diese Aufgabe erfindungsgemäß dadurch ge­löst, daß der thermoplastische Kunststoff bei Raumtemperatur formstabil ist und bei einer Temperatur von höchstens 200°C, vorzugsweise 150°C eine Viskosität hat, die ein Abtropfen gestattet. Auf die erfindungsgemäß ausgebildete Geschoßfang­vorrichtung auftreffende Geschosse dringen in das elastische Material ein und geben bei ihrem Durchgang relativ langsam ihre kinetische Energie ab. Der Schußkanal schließt sich auf­grund der Elastizität hinter dem eingedrungenen Geschoß. Eine Umlenkung von Geschoßteilen oder gar ein Geschoßrückprall ist daher mit hohem Zuverlässigkeitsgrad vermieden. Die Durch­schußsicherheit ist bei entsprechender Dickenauslegung in jedem Fall gewährleistet.Starting from a bullet trap of the type mentioned, this object is achieved according to the invention in that the thermoplastic is dimensionally stable at room temperature and at a temperature of at most 200 ° C, preferably 150 ° C, has a viscosity that drips allowed. Projectiles hitting the projectile safety device designed according to the invention penetrate into the elastic material and release their kinetic energy relatively slowly as they pass. The firing channel closes behind the penetrated projectile due to the elasticity. A deflection of floor parts or even a floor rebound is therefore avoided with a high degree of reliability. Bulletproofness is guaranteed in any case with the appropriate thickness design.

Da das thermische Material bei Raumtemperatur formstabil ist, erübrigen sich stabilisierende Seitenwände an der Geschoßvor­richtung.Since the thermal material is dimensionally stable at room temperature, there is no need for stabilizing side walls on the projectile device.

Ein besonderer Vorteil der Erfindung besteht in der einfachen Entsorgung der Geschoßfangelemente nach Erschöpfung ihrer Aufnahmekapazität. Eine Trennung des Geschoßfangmaterials von den Blei- oder sonstigen Geschoßteilen ist auf thermischem Wege problemlos möglich. Hierzu ist erfindungsgemäß vorge­sehen, daß die Schicht aus thermoplastischem Kunststoff eine Viskosität hat, die bei einer Temperatur von höchstens 150°C ein Abtropfen gestattet. Vorzugsweise sollte der Schmelzpunkt des thermoplastischen Kunststoffs unter 100°C liegen. Geeigne­te Materialien der Schicht aus thermoplastischem Material sind thermoplastisches Polyäthylen, Polyvinychlorid, Polyvinyl­äther, Polybutylen, Polyisobutylen, Polyacrylsäureester, Me­thylsilikon oder deren Copolimerisate oder Mischungen. Vor­zugsweise wird ein niedermolekularer thermoplastischer Kunst­stoff ohne Füllstoffe verwendet. Geeignet sind ferner die in Tabelle I angegebenen Coplymere und Derivate oder deren Mi­schungen.

A separation of the bullet trapping material from the lead or other bullet parts is easily possible by thermal means. For this purpose, it is provided according to the invention that the layer of thermoplastic material has a viscosity which allows dripping at a temperature of at most 150 ° C. The melting point of the thermoplastic should preferably be below 100 ° C. Suitable materials of the layer made of thermoplastic material are thermoplastic polyethylene, polyvinyl chloride, polyvinyl ether, polybutylene, polyisobutylene, polyacrylic acid ester, methyl silicone or their copolymers or mixtures. A low molecular weight thermoplastic without fillers is preferably used. The copolymers and derivatives or mixtures thereof given in Table I are also suitable.

Dem thermoplastischen Kunststoff kann auch ein Weichmacher beigemischt sein, der einerseits eine leichtere Einstellung der pyhsikalischen Materialeigenschaften als Formteile eines Geschoßfanges und andererseits eine Verringerung des Schmelz­punktes zur leichteren Trennung des thermoplastischen Kunst­stoffes von den Geschoßrückständen gestattet.A plasticizer can also be added to the thermoplastic, which on the one hand allows the physical properties of the material to be adjusted more easily than molded parts of a bullet trap and on the other hand reduces the melting point for easier separation of the thermoplastic from the bullet residues.

In Weiterbildung der Erfindung ist die Schicht aus thermopla­stischem Kunststoff aus wandartig zusammengestellten quader­förmigen Kunststoffblöcken gebildet. Derartige Kunststoff­blöcke lassen sich besonders einfach herstellen, beispielswei­se gießen oder aus einer größen Platte sägen und ermöglichen außerdem eine beliebige Größenzusammenstellung zu einer oder mehreren aneinander anschließenden Wänden.In a further development of the invention, the layer of thermoplastic material is formed from cuboid plastic blocks assembled in the manner of a wall. Plastic blocks of this type can be produced particularly easily, for example by casting or sawing from a large plate, and moreover allow any size combination to form one or more adjoining walls.

Auf der der Einschußrichtung abgewandten Rückseite der Schicht aus thermoplastischem Kunststoff kann eine Rückwand aus Stahl­blech, beispielsweise aus V2A angebracht sein. Diese Stahl­blechunterlage sorgt selbst bei geringerer Dicke der thermo­plastischen Kunststoffschicht für die notwendige Durchschußsi­cherheit. Die Kombination aus thermoplastischem Kunststoff und Stahblech bedingt daher eine geringere Gesamtdicke und hat im übrigen praktisch alle zuvor genannten Vorteile eines metall­freien Geschoßfangs. Diese Kombination aus einer thermoplasti­schen Kunststoffschicht und einem Stahlblech eignet sich be­sonders zur Herstellung einer transportablen Raumschießanlage. Vorteile einer solchen Gestaltung einer Raumschießanlage sind deren relativ leichtes Gewicht, deren absolute Durchschußsi­cherheit und Freiheit von Rückprallern oder querschlagenden Geschossen. Die wenigstens eine Lage von thermoplastischem Kunststoff hält die Geschosse und Geschoßteile zurück und läßt sich bei Erschöpfung der Aufnahmekapazität problemlos aus­wechseln, wenn - gemäß Weiterbildung der Erfindung - die thermoplastische Kunststoffschicht aus mehreren Platten be­ steht und die Platten an Haltestiften angebracht sind, die fest mit der Stahlblech-Rückwand verbunden sind.A rear wall made of sheet steel, for example made of V2A, can be attached to the back of the layer of thermoplastic synthetic material facing away from the weft direction. This sheet steel underlay ensures the necessary bulletproofness even with a smaller thickness of the thermoplastic layer. The combination of thermoplastic and steel sheet therefore requires a smaller overall thickness and, moreover, has practically all of the advantages of metal-free projectile trapping mentioned above. This combination of a thermoplastic layer and a steel sheet is particularly suitable for the production of a portable indoor shooting range. Advantages of such a design of an indoor shooting range are its relatively light weight, its absolute bulletproofness and freedom from rebounding or projectiles. The at least one layer of thermoplastic holds back the projectiles and parts of the projectile and can easily be replaced when the capacity is exhausted if - according to a further development of the invention - the thermoplastic layer consists of several plates stands and the plates are attached to retaining pins that are firmly connected to the steel sheet rear wall.

Zur Verringerung des Geräuschpegels im Einsatz der beschriebe­nen Geschoßfangvorrichtung kann auf der Einschußseite der thermoplastischen Kunststoffschicht eine schalldämmende Schicht beispielsweise aus Mineralwolle oder einem Textilvlies angeordnet sein.To reduce the noise level when using the projectile trap described, a sound-absorbing layer, for example made of mineral wool or a textile fleece, can be arranged on the entry side of the thermoplastic plastic layer.

Ein Verfahren zur Rückgewinnung von Formteilen der erfindungs­gemäßen Geschoßfangvorrichtung zeichnet sich durch die kenn­zeichnenden Merkmale des Anspruchs 12 aus. Diese einfache Art der Entsorgung des Geschoßfangs von Geschoß-, insbesondere Bleiresten, verbunden mit einem Recycling des Geschoß-Aufnah­meelements, verbilligt sowohl die Herstellung als auch den Betrieb der gesamten Geschoßfangvorrichtung.A method for recovering molded parts of the projectile trap according to the invention is characterized by the characterizing features of claim 12. This simple way of disposal of the projectile catch of projectile, in particular lead residues, combined with recycling of the projectile receiving element, makes both the manufacture and the operation of the entire projectile device less expensive.

Im folgenden wird die Erfindung anhand von in der Zeichnung schematisch dargestellten Ausführungsbeispielen näher erläu­tert. In der Zeichnung zeigen:

  • Fig. 1 eine Geschoßfangvorrichtung in der denkbar einfachsten Ausführung als aus Blöcken zusam­mengestellte Wand;
  • Fig. 2 eine andere Ausführungsform einer Geschoßfang­wand in mehrlagiger Ausführung; und
  • Fig. 3 eine Vorrichtung zum Recyclen eines benutzten Geschoßfangelements.
The invention is explained in more detail below on the basis of exemplary embodiments shown schematically in the drawing. The drawing shows:
  • Figure 1 is a bullet trap in the simplest possible form as a wall composed of blocks.
  • Figure 2 shows another embodiment of a multi-layer floor trap. and
  • Fig. 3 shows a device for recycling a used bullet trap.

Figur 1 zeigt einen Teil einer erfindungsgemäß aufgebauten Geschoßfangwand 1, bestehend aus mehreren nebeneinander und übereinander gesetzten quaderförmigen Blöcken 10 aus thermo­ plastischem Kunststoff. In dieser Auführung ist die Abmessung der einzelnen Blöcke in Schußrichtung 12 ausreichend groß bemessen, um das Geschoß innerhalb eines Blocks 10 zuverlässig bis zum Stillstand abzubremsen. Dies gilt auch für die Fugen 11 zwischen den Blöcken. Ein in Richtung des Pfeils 12 in die thermoplastische Kunststoffwand 1 eindringendes Geschoß wird praktisch kontinuierlich und relativ langsam in der Wand 1 abgebremst, dringt tief in die Wand ein und hält seine Form jedenfalls soweit bei, daß das Geschoß nicht wesentlich ver­formt wird oder auseinanderplatzen. Ein Rückprallen des Ge­schosses wird dadurch verhindert, daß die Kontraktionskräfte des thermoplastischen Kunststoffs den Einschußkanal relativ rasch hinter dem Geschoß schließen. Die Wand 1 kann durch geeignete Trägermittel an der der Einschußstelle entgegenge­setzten Rückseite 13 und/oder durch ein formschlüssiges Inein­andergreifen der einzelnen Kunststoffblöcke 10 an deren Fugen nach Art von Spielbausteinen in der Vertikalebene festgelegt sein.FIG. 1 shows a part of a floor trap wall 1 constructed in accordance with the invention, consisting of a plurality of cuboid blocks 10 made of thermo placed next to and above one another plastic plastic. In this listing, the dimensions of the individual blocks in the firing direction 12 are dimensioned large enough to reliably brake the projectile within a block 10 to a standstill. This also applies to the joints 11 between the blocks. A projectile penetrating into the thermoplastic wall 1 in the direction of arrow 12 is braked practically continuously and relatively slowly in the wall 1, penetrates deep into the wall and in any case maintains its shape to such an extent that the projectile is not significantly deformed or burst apart. A rebound of the projectile is prevented in that the contraction forces of the thermoplastic material close the bullet channel relatively quickly behind the projectile. The wall 1 can be fixed in the vertical plane by suitable carrier means on the rear side 13 opposite the entry point and / or by a positive interlocking of the individual plastic blocks 10 at their joints in the manner of toy building blocks.

Figur 2 zeigt schematisch eine Schnittansicht durch eine mehr­lagige Wandbekleidung 2, die erfindungsgemäß ausgestaltet ist. Wesentliche Komponente der Wandbekleidung 2 ist wie bei dem Ausführungsbeispiel gemäß Figur 1 wenigstens eine Schicht 20 aus thermoplastischem Kunststoff. Auf der der Einschußseite abgewandten Rückseite der thermoplastischen Kunststoffschicht 20 ist eine Rückwand 21 aus Stahlblech angeordnet. Mit der Rückwand 21 sind mehrere Haltestifte 22 und Anker 23 verbun­den. Auf den Haltestiften 22 sind die aus mehreren thermopla­stischen Kunststoffplatten bestehenden Elemente der Kunst­stoffschicht 20 aufgesteckt. Die Anordnung der die Geschosse abbremsenden thermoplastischen Kunststoffschicht 20 entspricht daher der aus Blöcken aufgebauten Kunststoffwand 1 des Ausfüh­rungsbeispiels der Figur 1. Auf der Einschußseite der thermo­plastischen Kunststoffschicht 20 ist eine Schicht, beispiels­ weise ein Vließ 24, aus schalldämmendem Material mit Hilfe der an der Stahlrückwand 21 festen Anker 23 angebracht. Die Wand­bekleidung gemäß Figur 2 kann mit anderen Wandbekleidungen gleicher oder ähnlicher Gestaltung zu einer Raumauskleidung mit rechtwinklig verlaufenden Wänden zusammengestellt werden. Dabei können Bodenplatten, Decken- und Seitenverkleidungen eine entsprechende Gestaltung haben und zu einer transportab­len Raumschießanlage zusammegestellt werden.Figure 2 shows schematically a sectional view through a multi-layer wall covering 2, which is designed according to the invention. As in the exemplary embodiment according to FIG. 1, the essential component of the wall covering 2 is at least one layer 20 made of thermoplastic material. A rear wall 21 made of sheet steel is arranged on the rear side of the thermoplastic layer 20 facing away from the entry side. A plurality of retaining pins 22 and anchors 23 are connected to the rear wall 21. The elements of the plastic layer 20 consisting of several thermoplastic plastic plates are plugged onto the holding pins 22. The arrangement of the thermoplastic layer 20 which brakes the projectiles therefore corresponds to the plastic wall 1 of the exemplary embodiment in FIG. 1 which is built up from blocks. On the entry side of the thermoplastic layer 20 there is a layer, for example as a fleece 24, made of sound-absorbing material with the help of the fixed to the steel rear wall 21 anchor 23 attached. The wall covering according to FIG. 2 can be put together with other wall coverings of the same or similar design to form a room lining with walls running at right angles. Floor slabs, ceiling and side panels can have a corresponding design and can be put together to form a portable indoor shooting range.

Das erfindungsgemäße Verfahren zur Gewinnung von Formteilen für eine der zuvor anhand der Figuren 1 und 2 beschriebenen Geschoßfangvorrichtungen werden im folgenden anhand eines in Figur 3 schematisch dargestellten Recycling-Ofens erläutert.The method according to the invention for obtaining molded parts for one of the projectile catching devices described above with reference to FIGS. 1 and 2 will be explained in the following with reference to a recycling furnace shown schematically in FIG.

Wenigstens ein Block 10 (oder eine Platte der thermoplasti­schen Kunststoffschicht 20) wird in einen Recycling-Ofen 3 eingesetzt und mit Hilfe einer Warmluftheizung 30 auf eine Temperatur oberhalb des Schmelzpunktes des thermoplastischen Kunststoffs gebracht, aus dem der Block 10 besteht. Diese Temperatur, die beispielsweise bei ca. 100°C liegen kann, ist deutlich niedriger als die Schmelztemperatur des niedrigst schmelzenden Geschoßbestandteils, insbesondere von Blei (327°C). Der benutzte und möglichst bis zur vollen Kapazität mit Geschoßresten beladene Block 10 wird durch die Wärmebe­handlung geschmolzen, und der geschmolzene Kunststoff läuft durch das Sieb 31 und/oder einen seitlichen Ablauf 32 nach unten. Im unteren Ende des Rycycling-Ofens 3 befindet sich eine Ablauföffnung 34, durch die das geschmolzene Kunststoff­material in eine darunterliegende Auffangform 35 abfließen kann. Die Form 35 kann als Gußform zur Ausformung eines neuen Blocks 10 dienen. Das feste Geschoßmaterial sammelt sich nach Schmelzen des Kunststoffmaterials auf dem Sieb 31. Unter Um­ständen ist es aber zweckmäßig, das wesentlich schwerere Ge­schoßmaterial auf einen Ofenboden, beispielsweise das Sieb 31 sedimentieren zu lassen und das eventuell etwas zähflüssige und schwer abtropfende Kunststoffmaterial seitlich abzuziehen, durch eine große seitliche Öffnung abfließen zu lassen oder auch abzuschöpfen. Bei seitlicher Abfuhr des Kunststoffmate­rials empfiehlt sich die Verwendung eines nasenförmigen Vor­sprungs 36, an welchem die unter dem Eigengewicht sedimentie­renden Geschoßteile, insbesondere Bleiteile zurückgehalten werden. Gegebenenfalls kann der Ofen 3 selbst auch mit einer geeigneten Kippvorrichtung zum Abgießen des geschmolzenen thermoplastischen Kunststoffs versehen sein.At least one block 10 (or a plate of the thermoplastic layer 20) is inserted into a recycling furnace 3 and brought to a temperature above the melting point of the thermoplastic material from which the block 10 is made by means of a warm air heater 30. This temperature, which can be around 100 ° C, for example, is significantly lower than the melting temperature of the lowest-melting projectile component, in particular lead (327 ° C). The block 10 used and, if possible, loaded to the full capacity with projectile residues is melted by the heat treatment, and the melted plastic runs down through the sieve 31 and / or a lateral outlet 32. In the lower end of the rycycling furnace 3 there is an outlet opening 34 through which the melted plastic material can flow into an underlying collecting mold 35. The mold 35 can serve as a mold for forming a new block 10. The solid projectile material collects on the sieve 31 after the plastic material has melted. In some circumstances, however, it is expedient to place the much heavier projectile material on a furnace floor, for example the sieve 31 Let sediment and the possibly somewhat viscous and hard-to-drip plastic material to the side, drain through a large side opening or skim off. When the plastic material is removed from the side, the use of a nose-shaped projection 36 is recommended, on which the projectile parts, in particular lead parts, which are sedimented under their own weight are retained. If necessary, the furnace 3 itself can also be provided with a suitable tilting device for pouring off the molten thermoplastic.
