Abstract

The arrow catch has a cover with a soft foam placed on a front and back side, where side walls of the cover is made of stiff and hard material such as wood or fiber boards. The cover comprises a form-stable foam material and a filling made of loose or brake material, which is not stand and flak-fixed. The foam material has a density between 0.15 and 0.35 kilogram/litre, firmness of more than 0.5 MPa, and a fusion or decomposition temperature of more than 250 degree celsius.

Description

The Invention relates to arrow length for targets according to the generic terms of the claims 1 and 15. Such arrow length be for the archery needed and for other sports involving shooting with arrows, e.g. Crossbow.

• • Er soll den Pfeil sanft genug abbremsen, damit keine Beschädigungen am Pfeil auftreten.
• • Der Pfeil soll zuverlässig an der Position abgebremst werden, an der er auftrifft, um dem Schützen die Zielgenauigkeit seines Schusses anzuzeigen und bei Turnieren den Erfolg der konkurrierenden Schützen vergleichen zu können. Dies bedeutet, der Pfeil soll nicht abgelenkt werden und darf auch nicht gelegentlich von der Zielscheibe abprallen.
• • Der Pfeil soll von Hand wieder aus dem Pfeilfang gezogen werden können.
• • Aus Sicherheitsgründen soll der Pfeil keinesfalls so abgelenkt werden, dass er in einer anderen Bahn weiterfliegen und jemanden verletzen könnte.
• • Der Pfeilfang soll sich innerhalb des Verlaufes eines Turniers durch den Beschuss nicht so verändern, dass eines der vorangegangen Kriterien nicht mehr erfüllt ist.

The arrow catch of a target has several tasks:

• • It should slow down the arrow gently enough to prevent damage to the arrow.
• • The arrow should be decelerated reliably at the position it hits, in order to show the shooter the accuracy of his shot and to compare the success of competing shooters in tournaments. This means that the arrow should not be distracted and should not occasionally bounce off the target.
• • The arrow should be pulled out of the arrow by hand.
• • For safety reasons, the arrow should never be deflected so that it could fly on another lane and injure someone.
• • The arrow-catch should not change within the course of a tournament by the shelling so that one of the preceding criteria is no longer fulfilled.

• • Lange Lebensdauer auch bei häufigem Beschuss. Diese Eigenschaft ist aus wirtschaftlichen und ökologischen Gesichtspunkten wichtig.
• • Geringes Gewicht, damit die Zielscheibe ohne Hilfsmittel transportiert werden kann, z.B. wenn im Verlauf eines Turniers die Zielscheiben auf eine andere Distanz gestellt werden müssen.
• • Möglichst breiten Funktionsbereich, d.h. es sollen möglichst einerseits dünne Carbonpfeile (auch Verbundmaterialpfeile mit Carbonfaseroberfläche), die von einem starken Compoundbogen geschossen wurden, ebenso sicher abgebremst werden, wie dickere Aluminiumpfeile, die von einem Kinder-Recurve-Bogen abgeschossen wurden.
• • Es sollen sich beim Eindringen des Pfeils in den Pfeilfang keine Beläge auf dem Pfeil bilden, da diese die Balance und die Aerodynamik bei den folgenden Schüssen ändern könnten.
• • Witterungsbeständigkeit, damit die Scheibe die Saison über im Freien auf dem Schießplatz belassen werden kann.
• • Beim Verschleiß während der Benutzung soll möglichst kein oder nur sehr wenig Schmutz oder Staub an die Umgebung abgegeben werden. Dies ist besonders bei der Verwendung in Innenräumen von großer Bedeutung.
• • Bei der Benutzung oder der Entsorgung (beispielsweise der Verbrennung zur Energiegewinnung) sollen keine giftigen Stoffe an die Umwelt abgegeben werden. Hierzu ist eine Halogen- und Schwermetallfreiheit anzustreben.

Other desirable properties for arrow length are:

• • Long life even with frequent bombardment. This property is important from an economic and ecological point of view.
• • Light weight, so that the target can be transported without aids, eg during a tournament the targets have to be moved to a different distance.
• • As wide a range of functions as possible, ie on the one hand thin carbon arrows (also composite arrows with carbon fiber surface), which were shot by a strong compound bow, as surely braked as thicker aluminum arrows, which were shot down by a children's recurve bow.
• • There should be no pads on the arrow as the arrow enters the arrow catch, as these could alter the balance and aerodynamics of subsequent shots.
• • Weather resistance so the disc can be left on the field for outdoor use during the season.
• • During wear and tear, as little or as little dirt or dust as possible should be released into the environment. This is especially important for indoor use.
• • During use or disposal (for example, incineration for energy), no toxic substances should be released into the environment. For this purpose, a halogen and heavy metal freedom should be sought.

are Figure precision and durability with each other competing properties, so can Arrow catches, which for the practice area used and shot at very often, the emphasis on the Durability at the expense of precision be placed.

Mechanics of function:

One Arrow weighing 30 g, with a powerful sports bow is shot down, leaving the bow at a speed of about 200 km / h. This results in a kinetic energy of up to to 45 joules, which degraded within a braking distance of 10 to 20 cm shall be. In the case of the crossbow, the energy is usually higher and higher the braking available Arrow or bolt length still shorter. This increases the requirements for the arrow catch.

• 1. Mechanische Zerstörung
• 2. Plastische Verformung
• 3. Elastische Verformung
• 4. Massenverdrängung
• 5. Reibung

The energy reduction takes place in arrow lengths via several mechanisms that always occur in combination with each other depending on the material with different center of gravity:

• 1. Mechanical destruction
• 2. Plastic deformation
• 3. Elastic deformation
• 4. mass suppression
• 5. friction

The relationship the five Components decide Handling and life of a target.

The Size of the components 1 and 2, the mechanical destruction and the plastic deformation, ultimately decide on the Lifetime of the arrow catch.

The Destruction, and the plastic deformation (components 1 and 2) of an arrow catching material in the firing channel, lead that an arrow in a subsequent shot, the same Spot hits, at this point now experiences less resistance and penetrates deeper, destroying material lying further back. He will later braked, since the friction alone is insufficient, the next arrow to stop at the same position. A darts catch, one as possible low tendency to destruction When shelling is required, must be made of a tough and abrasion resistant material consist. The higher the proportion of elastic deformation (component 3) in the firing channel, the lower the destruction.

The Component 4 for The energy reduction, the mass displacement, is especially important Targets with higher Mass to bear. The work done by a penetrating arrow must to side to the lying in his path material parts move, carry also for braking at. By a high mass becomes the arrow catch however heavier and as a result of this unwieldy. This is therefore more likely for crossbow disks applied, which are much smaller. In a combination disc with replaceable center this can be made of the heavier material exist and the entire arrow catch still remain handy.

The Component 5, the friction leads to a heating of the materials at the relevant interface. arrows with metal surface (usually an aluminum alloy), this heat can dissipate faster as carbon fiber arrows, which are therefore more critical. Consists of the arrow catching material from a fusible link, so the friction energy can Material may exceed the melting point heat, leaving it on the arrow surface sticks. This is a problem especially with polyethylene foams, as it is for destruction contributes to the disc and additionally soiled the arrow, cleaning it after each shot must be rubbed off by rubbing off the PE coating. Will not this done consistently after each shot, so will the balance and changed the aerodynamics of the arrow, which results in other flight characteristics and therefore decreasing precision Has. In principle, every thermoplastic has the problem that it is at enough high friction energy melts. For infusible materials important that the decomposition point is as high as possible. To prevent, that decomposition products of the arrow catch settle on the arrow surface, can be added to the material a release agent. Below are for example natural and synthetic oils, mineral oils, as well as silicones and others as release agents in plastics technology to name used additives.

Farther is a high wear resistance of the material of great advantage for the life of an arrow catch.

State of the art:

Of the Market at Pfeilfängen is currently in several, basically split different systems:

Straw, bound or braided:

Very simple and inexpensive Arrow length exist from straw, to bundles tied together and spiraling to a round surface is rolled up and through twine is held together.

Disadvantage:

at This construction type meets the arrow perpendicular to the fiber direction on and through the fibers transversely, whereby these are greatly shortened and strength to lose. Such arrow length wear out very fast, because the energy reduction predominates due to mechanical destruction.

Ethafoam:

Of the much used polyethylene foam, mainly for the packaging industry is available in different density settings, the versions with higher Densities often Also used as a darts catch in archery. Polyethylene foam arrow length brake the Arrow gently and are characterized by their low specific gravity good to handle.

Disadvantage:

• • Brake the Ethafoam arrow length Carbon arrows shot from strong compound bows do not enough, so that it can come through. Thereby the arrow can be damaged and the hit position is incomprehensible.
• • There Polyethylene melts even at relatively low temperatures is the arrow is coated with a layer of melted PE during braking, which needs to be scraped off after each shot to balance and aerodynamics of the arrow do not change,
• • By the low elasticity and toughness of the polyethylene, the foam structure is penetrated by the Arrow destroyed locally, being a relatively large one Hole remains and the arrow length wear out of it therefore speedy.

Because of fast wear Be polyethylene foam arrow length often with replaceable center (exchange core) offered.

Karphos / Stramit:

at Karphos are pressed and cardboard-wrapped straw plates, cut into strips one above the other Stacked to form a darts catch. The straw is there oriented in the weft direction, so that a penetrating arrow the Straw not destroyed transversely to the grain, but parallel to the Fibers penetrate and by displacement the fibers and friction on the surface is braked.

The braking of the arrows is very effective in this technique and also arrows with high energy gie are reliably stopped, since the energy reduction is accomplished mainly by mass displacement, elastic deformation and friction. The arrows can be drawn well because there are no attachments to the arrow. This is due to the infusibility of the straw. Karphos is only slightly damaged by the shot, so it is much more durable than polyethylene foam.

There It has a high density and the target therefore a heavy weight Karphos discs are very heavy and especially in size 125 * 125 cm for the long FITA distances (70 m and 90 m) from a single person hard to handle. this leads to Combinations offered by many manufacturers where the strongest loaded center of Karphos and the less frequent and less densely hit Peripheral of the arrow catch consists of Ethafoam.

• • Im Neuzustand bietet Karphos einen hohen Widerstand gegen eindringende Pfeile, so dass dickere Aluminiumpfeile, die mit einem Kinderbogen oder einem leichteren Damenbogen geschossen werden, nicht eindringen, sondern abprallen können.
• • Beim Ziehen der Pfeile kommt es häufig vor, dass einzelne Strohhalme mit heraus gezogen werden, so dass der Pfeilfang an dieser Stelle mit jedem fehlenden Halm zunehmend geschwächt wird. Im Laufe eines Turniertages kann dies zu einem Zerfall des Pfeilfangs im Zentrum führen, so dass dieses ausgetauscht werden muss. Gleichzeitig entsteht vor der Zielscheibe ein kleiner Haufen aus Staub und Stroh. Dies ist besonders bei Verwendung in geschlossenen Räumen unerwünscht.
• • Die Strohplatten sind in einem stabilen Karton eingepackt und viele solcher Platten werden übereinander gestapelt und verspannt. Dabei entstehen auf der Scheibe durch die beiden Kartonlagen Streifen, welche einen noch höheren Eindringwiderstand aufweisen, als das Stroh-Material darüber und darunter. An dieser Stelle kann es bei weniger energiereich geschossenen Pfeilen zum Abprallen oder der Verfälschung der Schussabbildung kommen.
• • Das verwendete Stroh ist ein Naturprodukt und hat in den Stängeln neben Zellulose auch eingelagerte Kieselsäurepartikel, sowie anhaftenden Staub und Schmutz. Diese können sehr hart sein und abrasiv wirken. Ein Pfeil, der häufig auf eine Karphos-Scheibe geschossen wird, zeigt eine messbare Abnahme der Materialstärke im vorderen Bereich. Dadurch ändern sich Balance und Steifigkeit des Pfeils ungleichmäßig, was die Präzision beeinträchtigt.

Karphos has in addition to the high weight but still other disadvantages:

• • When new, Karphos offers a high resistance to penetrating arrows, so that thicker aluminum arrows, which are shot with a children's bow or a lighter female bow, can not penetrate, but can bounce off.
• • When pulling the arrows, it often happens that individual straws are pulled out, so that the arrow catch is weakened at this point with each missing blade increasingly. In the course of a tournament day this can lead to a decay of the arrow catch in the center, so that this must be exchanged. At the same time, a small pile of dust and straw is created in front of the target. This is undesirable especially when used in confined spaces.
• • The straw plates are packed in a sturdy cardboard box and many such plates are stacked and braced. This creates on the disc through the two layers of cardboard strips, which have an even higher penetration resistance than the straw material above and below. At lower energy shot arrows, bounce or falsification of the shot image may occur.
• • The straw used is a natural product and has in the stems next to cellulose also embedded silica particles, as well as adhering dust and dirt. These can be very hard and abrasive. An arrow that is often shot at a Karphos disc shows a measurable decrease in material thickness at the front. As a result, the balance and rigidity of the arrow change unevenly, which impairs the precision.

Arrow length of fabrics:

It There are different types of arrow lengths in the market that are made Plastic foam films with a few millimeters of strength to roles are wound. These are welded or glued between the layers, so that the arrow in the rear part more clamped and thus slowed down and the layers will not slip against each other. Since normally on a core is wound, this can easily be replaced later become.

Disadvantage:

These Sort of slices has a similar disadvantage like polyethylene foam. The material can melt on the arrow surface and thereby make a cleaning necessary. Partially being from the suppliers silicone solutions and silicone emulsions for coating the arrows offered to the To reduce the melting and sticking of target material, or to avoid. This means unpleasant handling with greasy liquid and uncontrolled influence on weight and aerodynamics of the Arrow.

moreover it comes with these discs again and again to hits, at which the arrow is not passed between two layers, but destroyed the foil layer. For cost reasons Here, for example, the use of highly wear-resistant Polyurethane films. The commonly used PP or PE does not have the necessary Strength and toughness, to withstand a penetrating arrow and this between the Derive layers. As a result, these discs wear out relatively swiftly become unsightly and let down in their function.

Loose materials in envelopes:

isolated is there arrowhead, from a shell made of fabric and a cotton filling consist. Occasionally, a second, non-penetrable barrier layer provides behind the cotton filling for this, that the arrow catch is not shot through. The concepts work like a pillow, the stronger compresses the filling is, the stronger the pillow bulges in the direction of a round shape. Since tissue at frequent shelling wear out quickly and there is no viable repair option for a damaged center the entire arrow catch is relatively fast waste. By the leaves little defined shape The arrow catch is difficult to set up in a rack and makes not a professional impression. There is no plane surface on a paper printed with concentric circles (mirror) could be stapled.

Task of invention

It The object of the invention to provide a dart catch, the Energy reduction as little as possible via mechanical material destruction accomplished, but largely about elastic deformation, Friction and mass displacement, the arrow catching material is not affected by the heat that occurs melt or destroy shall be. The arrow catch should wear out as slowly as possible and over the entire life its function unchanged.

These Task is governed by the objects of claims 1 and 15 solved. The other claims represent advantageous embodiments.

The The object is achieved by a arrow catch according to the invention for a target solved, the one shaping shell comprising, containing a stable foam material and a filling loose or only slightly bonded brake material for alone would not stand and bulletproof.

The filling from loose brake material in a foam forming outer skeleton the economic advantage that such brake material usually very cheap and in big Amount of waste available is. Technically, the big advantage to see that the brake material rearrange again and again and can reorient and the firing channel of a drawn arrow through a later Hits nearby by shifting the loose braking material (e.g., particles) is pushed. As a braking material, split by the arrow or can be perforated, still has the same mass and through the elastic foam layer can not fall outside, reduced The braking effect hardly, since the energy dissipation of the arrow mainly via mass displacement work and surface friction happens. Furthermore, loose brake material has the advantage that it also later can be exchanged to adjust the arrow catch for other energies. For the Use with crossbow bolts or thin carbon arrows of strong compound bows For example, a filling with rubber granulate, e.g. out shredded car tires or cellular high-density polyurethane (e.g., shredded bumpers from the automotive strut). These brake materials have the advantage of high toughness and are also due energetic arrows not destroyed, but displaced. Should a sagging, or sitting together avoided by compaction can be subdivided into chambers. Alternatively, the brake material by adding little binder (elastic adhesive) are stabilized. Has a loose filling the further advantage that high-energy arrows not by extreme clamping be braked, which complicates the subsequent pulling the arrows. The chamber can also be divided into several levels, with fillers can be filled with increasing mass, density or toughness. Thereby can universal arrow length which are both arrows of children's arches, as well as strong compound bows at the same time brake effectively.

Another advantage of an arrow catch from a shaping shell with loose filling is the creative freedom. This makes it possible, for example, to equip the most loaded center of the arrow catch with a removable core, which can be constructed of a higher quality material and interchangeable (see, eg 1 ). Also arrow length in the form of an animal model can thus be produced in principle. According to the embodiment in 1 the shaping foam shell is composed of several individual components, which are connected to each other after filling with the loose brake material, for example by gluing. As an alternative to this embodiment, the forming foam sheath can also be constructed of only two components, namely a mold, in which the brake material is filled, and a matching front plate for closing the mold.

Especially polyurethane foams are for the shaping shell very suitable because they are almost arbitrarily adjustable in their properties are. Especially soft foams with a density above 0.1 kg / l can in their tenacity and elasticity, paired with the infusibility be formulated as they are for one Arrow catch of high quality necessary are. With more or less big restrictions Virtually all other soft foams can be used for this Use purpose. These include, for example, foam rubber, sponge rubber, Polyethylene, EVA foam, phenol-formaldehyde resin foam, etc. to call. Foam only has to be the front panel. The Side walls, as well as the back wall can made of any material that is so high enough Has inherent rigidity to give the arrow catch the shape. Among them are especially wood and technical fiberboard too especially Pressspan and OSB (oriented strand board).

The Task is also by a Pfeilfang invention for a target solved, at the surface its front evenly spaced openings which are structured such that an impinging arrow without mechanical destruction or plastic deformation but with elastic deformation and friction can penetrate into the front.

The fact that in the arrow catch a perforation structure is given, the arrow a Gives way, on which he does not have to destroy any material, but merely clamped and braked by the resulting friction. As a result, the shot channel remains unchanged on the top plate at successive hits to the same place and the function of the arrow catch is maintained. Advantageously, the surface is provided with a compact, elastic material with high toughness. As a result, high-energy arrows are reliably dissipated in the predetermined holes and superficially no destruction on. Suitable formulations can be found especially in the class of polyurethane casting resins. The front layer can preferably be deposited with a layer of flexible foam in which the hole structure continues more or less far, so that the entire front panel obtains a sufficiently high inherent rigidity, which allows the construction of a flat front of the entire target without being very difficult.

Next This alternative embodiment can perforate the invention Front also additive, i. in combination with loose brake material in a shaping shell be used in an advantageous manner.

Especially advantageous is a funnel-shaped design the openings in the front of the arrow catch. This will ensure that the incoming arrow on the surface The arrow catch at any point finds an oblique surface, which him in a Hole passes. Due to the high energy of an arrow from a bow or a crossbow, it is advantageous to have the material on the surface of the Arrow catch very tough and to choose elastic so it will not be destroyed soon becomes.

The funnel-shaped front gently guides the arrow on its way into the center of the hole, which the arrow has to widen when penetrating. Due to the widening of the channel from the predetermined diameter to the diameter of the arrow, a tension is created which increases the friction between the target disc channel and the arrow surface and thus brakes the arrow. The main brake work is then done by the underlying brake material (see 2 ).

If the holes are not preformed over the entire cross section of the hole front, but only up to a part of the layer thickness of this front, so the first penetrating arrow extends the hole by piercing this foam barrier in the hole front, with a slight destruction is achieved. This now torn hole closes when pulling out the arrow by the elasticity of the foam again. This construction of the front panel prevents dust or small particles of the filling from being able to escape to the outside (see 3 ). For the function of the entire arrow catch these minimal damages are irrelevant.

Of the funnel-shaped Inlet into the preformed holes may show a gradually or gradually increasing angle to the surface so that the webs between the holes enough Have material to the required strength and toughness to obtain.

By additions of liquid or solid lubricants in the formulation of the surface material let yourself significantly facilitate the pulling of the arrow.

There a predetermined perforation structure the arrow by derivation in the hole slightly deflected from the trajectory, a falsification of the shot results at the display. This can be taken during training, if this protects the material. Such a arrow catch can on the opposite side equipped with a soft foam layer with a smooth surface be so he for Competitions and tournaments when it comes to pristine results display, just turned around and shot at the unstructured side can be.

to renewal the life and in addition to increase The rigidity of the overall system can also be a darts catch with a be equipped interchangeable core.

Further advantageous embodiments are given in the dependent claims.
