B. Synthesis and / or Natural rubber.

Description

The The invention relates to a 2D or 3D target object, in particular for Bow, crossbow or darts, according to the preamble of the protection claim. 1

in the Shooting with arrows (especially bow, crossbow and darts) will target objects such. B: 2D slices or so-called. Used 3D objects.

For the 2D targets or 3D objects, such. B. animal representations, many materials are used. Currently these are cork, pressed Straw, pressed foam flakes, plastics (PE) or foams (PU).

The DE 29819518 U1 discloses a shooting disc made of at least 2 cm thick plastic plate made of an elastomer, for a variety of shooting sports disciplines. Due to the consistency of the material used, the shot hole in the disc closes immediately after penetration of the projectile.

The DE 3839000 A1 discloses a bullet trap with at least one layer of tough, thermoplastic material. As a thermoplastic material also methyl silicone [(CH ₃ ) ₂ Si-O] _n specified, as copolymers or mixtures with z. For example, PE, PVC, PB. The thickness of the layer of thermoplastic material is at least dimensioned in the weft direction so that a projectile is slowed down when it penetrates into the plastic layer to a standstill. The shot channel closes due to the elasticity behind the penetrated projectile.

The DE 2557153 A1 discloses a target, in particular for archery, with a plurality of superimposed membranes of lamellar plastic material and a plurality of sandwiched between the membranes and these spaced intermediate layers of elastic and porous material, wherein the membranes formed elastic and tear resistant and from one to the target Pierced arrow pierceable and the elastic and porous intermediate layers are also pierced by an arrow and allow the formation of a sleeve-shaped, cooperating with the arrow in the region of the bullet hole ring portion of the membrane which frictionally cooperates with the shaft of an arrow penetrating into the target and after the Pulling out the arrow partially re-deformed. The lamellar plastic material is specified as polyethylene, the elastic and porous material as a polyolefin foam.

The DE 8325942 U1 discloses a bullet trap device in particular for indoor shooting ranges, consisting of a filling of several columns stacked annular rubber body such. B. (old) vehicle tires, wherein the cavity of each column is filled with a readily flowable material in bulk, which may be rubber, rubber, or plastic granules. Also in this document is the older DE 8023429 named, which fills the space behind the target device with rubber granules of old vehicle tires.

The DE 8209799 U1 discloses a bullet trap, in particular for shooting in closed spaces, wherein behind the target plant a wall is constructed, which consists of a granules of garbage, in particular of vehicle tires, which by a binder, for. B. synthetic resin or permanently elastic plastic such as PUR, is fixed. In the shooting direction in front of the granule layer, a one-piece front plate is preferably applied from the same material as the granules on the granule layer.

The DE / EP 0186682 T1 discloses a bullet trap especially for small-caliber indoor shooting ranges and shooting ranges, with a granular mass of foamed material made of foamed or unfoamed plastic, or foam in the form of powder, granules, garbage or chips, granular food, cork, populite wood chips, chips and powders of tires, cork wastes, feathers, wood chips, sawdust, hay, and other dried grasses, expanded materials, and artificial powders and artificial granules.

The DE 3426458 A1 discloses a bullet-resistant laminate, in particular for protective vests, comprising a multiplicity of fabric layers which consist entirely or predominantly of aramid fibers or other high-modulus fibers (such as polyamide) and optionally other synthetic fibers and are bonded together with binder, the binder layers being essentially only are provided between the fabric layers and the interior of the threads is substantially free of binder. As state of the art in this document it is stated that protective vests exist which, as the sole holding element, have a certain number of layers of aramid weave and are capable of stopping projectiles at speeds of up to 500 m / s. The required number of layers depends mainly on the type of tissue, the bullet velocity and the bullet shape. The required number of fabric layers may be less if the individual layers are arranged closely spaced as close to each other as possible, in which case 15 to 30 layers are specified here. Furthermore, the fabric layers after Furthermore, the state of the art states that the fabric layers can be glued together or the type of GRP technique can be laminated by means of resins, but this is also the case for the state of the art The laminate of the DE 3426458 A1 has an elongation of only 4% (breaking tensile strength) and a modulus of elasticity of 59 GPa. The optimum number of threads per cm 12 is given in the warp and weft of the aramid fabric.

Individually or cumulatively, these materials have the following disadvantages:
Insufficient weathering resistance, inadequate resistance to aging, short life on decision, loud noise and / or heavy removal of the arrows.

task The present invention is therefore, a target or general a 2D or 3D target object of the generic Type to continue to form such that the highest possible life of the target object and the highest possible noise attenuation is reached when the bullet enters the target object, as well the removal of arrows with little manual power allows is, the target or the target still inexpensive is.

to Solving the tasks put serve the characteristics of the Protection claim 1.

Essential It is the case that one after the other in the weft following variety of layers of at least one net-shaped element of elastic deformable silicone material and / or elastomers such. B. Synthesis and / or natural rubber as an energy absorption layer for the penetrating bullet is present.

advantage is that the kinetic energy of the projectile (eg arrow) in the Essentially not by penetrating the material of the energy absorption layer and moving forward in this material is degraded, but by counter-tensile forces of the elastically deforming nets, which counteract the firing force of the penetrating projectile. Given a variety of layers of one or more networks are, take the counter-pulling forces with increasing depth of penetration in the target object too. This is a "strike through" of the target object almost impossible, so that a destruction hardly possible is. After the low-power removal of the projectile from the target object is also no closing of selectively opened material Nets, because the projectiles are not, or at least only in a negligible degree, in the material have penetrated.

further developments are the subject of the dependent claims.

Especially are a variety of in the firing direction directly above each other lying flat or corrugated nets, but can also a single or a few folded or coiled ones Networks exist. The important thing is always that in the firing direction several layers or layers of power supplies lie behind each other and thus the kinetic energy of the projectile (eg arrow) be degraded by the elasticity of the net material can. The mesh openings of the nets are in the weft direction not aligned congruent, but slightly shifted, so that by the multiplicity of layers altogether the impression of a closed solid material, since you can not get through the target can look through. Nevertheless, it is a Network structure, which is just a variety of in the weft direction each other Having resting network layers.

Prefers when using nets, a mesh size that is equal or greater is, as the diameter of the projectile across the weft direction. So that the bullet can penetrate into the mesh opening and is so due to the frictional forces and on the ground slowed down the elastic counterforce of the material of the nets. But it can also be provided a smaller mesh size, the smaller than the diameter of the projectile across the weft direction. Also any combination of different mesh sizes per network or in the same network would be possible.

Advantageous is a variety of networks of silicone material as an energy absorption layer used, which lie directly flat against each other.

In other embodiments may instead of networks also star-shaped structures made of silicone or elastomer / rubber be used, which then together in mutual overlay or Toothing again form a reticular element, with similar Properties, like the networks of one piece.

Prefers The nets extend in a plane approximately transversely to the firing direction of the projectile, but also in an angle or even parallel to Weft direction of the projectile be arranged, or in one any different orientation or even folded or be geknäuelt and in the weft direction next to and behind each other lie.

Also, between the individual networks of the energy absorption layer can be more elas be provided table deformable or penetrable thin layers of the same or different material. In particular, silicone granules are preferably suitable for this purpose from production waste.

Around To give the nets sufficient support, these are in one introduced on one side in the firing direction open frame, the off a solid material such as plastic, wood or metal formed is. The open side of the frame is covered with a repeatedly releasable covered in a closed lid, made of an elastic Material (eg silicone, elastomer / rubber) is formed. In this lid are target and counting devices opened and / or inserted, such as As rings, numbers, letters, figures, etc ..

The Target objects (slices, other 2D and 3D objects) should be completely or partially made of elastomers, in particular silicone, in a multilayered Construction are made. Elastomers, especially silicone, offer a water-repellent, weather-resistant and age-resistant Material. Through a multi-layered structure with different Material consistencies are long life, a daring Endrings and a very simple arrow removal allows. Due to the soft elastomer, the arrow penetrates almost silently.

About that In addition, due to the multi-layered construction as additional Option a target representation integrated into the target or target in the form of numbers, rings or other graphic or pictorial Presentations possible.

Next the reticulated layers according to the invention, physically lead inhomogeneous layers through the material conditional repeated "new entries" to a high energy absorption without significant material loads. The inhomogeneous material layer, made of a wide variety of fillers with and without air trapping can exist after the penetration of the arrow only more a small lateral pressure on the arrow shaft. hereby can be a removal with much less effort than before respectively. Reduce by the complexity of the filling the effects of permanent damage by the penetrated arrow. This will additionally a longer Lifetime achieved.

in the The invention will be exemplified with reference to drawings explained in more detail, the further features of the invention reveal.

It shows:

1 : Schematic representation of a first embodiment of the target according to the invention in section along the weft direction;

2 : Top view on 1 with lid removed and removed nets;

3 : Schematic representation of a second embodiment of the target according to the invention in section along the weft direction.

1 and 2 show a first embodiment of the invention in the form of a circular cylindrical cross-section target 10 in axial longitudinal section in the weft direction 19 ,

It will now be the layers of the target 10 in the weft direction 19 described in more detail.

First, a bullet (eg arrow) hits an interchangeable faceplate containing a permanent targeting layer 1 , as well as one in firing direction 19 seen behind it a subsequent layer of filler 2 , The replacement of the front panel is done simply by a radially extending drawstring, which also occurring transverse forces when entering the projectile in the target 10 counteracts. The front panel consists of several layers of silicone or other elastomeric materials. As a result, an exact graphical target representation can be produced.

The target presentation 1 can be poured homogeneously, with z. B. rings are colored accordingly (thermally connected). The production of the rings can also be done separately (eg with presses) and then fit together accurately. Since the individual rings are exchangeable, the service life is considerably higher (in general, the disk center is time-determining). An enormous number of different materials are applicable. For example, paper, cloth, sand, and even organic materials such as leather or plants, as well as pine cones and many other materials. The objects completely enclosed by silicone enter into a homogeneous connection after the thermal process, in the annealing oven for 4-12 hours at 200 ° C. This thermal treatment is possible due to the lack of oxygen. Due to the homogeneity a considerable destruction by projectiles of every kind is practically impossible. The inlet and outlet channels close immediately, almost water-like. The target is shot through, but it loses its embedded position, nor the original structure.

In the direction of the shot 19 seen behind, joins the front panel 1 . 2 one or more removable cover plates 3 An a frame 8th seen in the weft direction covers the front.

In the direction of the shot 19 seen behind it, joins the cover plate 3 as filler a variety of layers of nets 4 all in the frame 8th are included, which has a final floor 9 having. This filler 4 is complexly installed, ie the mesh layers are "interwoven", so that a positive effect with regard to the "rubber forces" arises because enormous frictional forces arise.

Between the layers of nets 4 and the floor 9 is an optional layer 6 provided with spirally or helically rolled-up tubes whose spirals transverse to the weft direction 19 expand (see 2 ). There can be different spirals 6 be present, wherein the resulting pressure of the compressed air at pressure load with the incoming arrows is authoritative. This allows to the center of the target 10 Reinforcement takes place, since basically there the material load is higher. The hose spirals 6 are laid with metal pins and fixed. After adjusting the cover plate 3 these are pulled out at the back. With these hose spirals 6 creates a pressure force to the front.

Between the cover plate 3 and the floor 9 is a fixation cord 5 by means of adjusting screw 7 looking forward to the cover plate 3 firmly on the network layer 4 and the spiral layer behind it 6 to pull and the frame 8th properly cover.

To the filler 4 from network layers:

So far Only the resulting ring bulge was solid when penetrating Silicon substances are considered for absorbing the projectile energy. Disadvantage is the heavy arrow removal, since the bead is tight around pull the arrow. Another disadvantage is the relatively short life, since a destruction of the filling material takes place. Right in the center of the target is the absorption of the projectile energy only punctually place, whereby the arrow much deeper into the Material of the target penetrates and as a result the removal of the arrow is much more difficult.

advantage by introducing the silicone networks according to the invention, or other materials of the same structure is that only in the Entry phase of the projectiles comparable to a torus Absorption takes place.

To completed entry of the projectile relaxes the net-like Filler again and the elastic stress from the silicone / elastomer, which has stopped the bullet, is reduced, so that the arrow much easier to remove.

• 1. Durch eine permanente Zieldarstellung entfallen die Kosten von sonst üblichen Papierauflagen. Vereine oder auch Privatpersonen können enorme Kosten einsparen und gleichzeitig umweltschonend trainieren. Natürlich können auch weiterhin handelsübliche Ziele in Kombination mit den erfindungsgemäßen Silikonnetzen verwendet werden.
• 2. Enorme Haltbarkeit, da nur die auswechselbare Frontplatte einen nennenswerten Verschleiß aufweist und diese kostengünstig und einfach zu wechseln ist.
• 3. Variabler Einsatz, je nach Beanspruchung und gewünschter Art der Ziele kann die Frontscheibe in wenigen Minuten neu einsatzbereit sein. So können auch im Vereinsbereich individuell vom Schützen bevorzugte Frontplatten eingesetzt werden, da gerade Compound-Bogen die Scheiben stark belasten.

Further advantages of the silicone nets according to the invention are:

• 1. Permanent targeting eliminates the cost of paperwork. Clubs or private persons can save enormous costs and at the same time train in an environmentally friendly way. Of course, commercially available targets may continue to be used in combination with the silicone meshes of the present invention.
• 2. Enormous durability, since only the replaceable front panel has a significant wear and this is inexpensive and easy to change.
• 3. Variable use, depending on the load and the desired type of targets, the windscreen can be re-used in a few minutes. So also in the club area individually preferred from the shooter front plates can be used, since just Compound bow load the discs heavily.

3 shows an alternative second embodiment of the invention in the form of a circular cylindrical cross-section target 20 in axial longitudinal section in the weft direction 19 ,

It will now be the layers of the target 20 in the weft direction 19 described in more detail.

First a bullet (eg arrow) hits a dimensionally stable, thin, but hard penetration layer 11 , which is not only advantageous in terms of overall statics, but also by a kind of "rubber effect" throughout the entire body of the target 20 takes place. By compression in the entry point of the projectile, a tensile stress is built up, which extends through the entire body of the target 20 runs and thus counteracts the kinetic energy of the projectile. The penetration layer 11 runs around the entire target 20 and is self-contained.

At the jacket-surface and rearmost ie bottom-side parts of the penetration layer 11 closes as an outer body a tub 12 made of plastic geometrically independent, which is dimensionally stable and weather-resistant, with coated metals, and wood are suitable.

In the direction of the shot 19 seen behind it connects to the penetration layer 11 a soft poured silicone layer 17 which is a graphical target representation 13 fixed, which is not completely "resistant", ie is optically stable on hits of the projectile, but is permanently suitable seen from the usual distances.Emission channels are to be recognized only from a small distance.Better optical properties are made by coloring this layer 17 and or 13 z. B. achieved in ring shape, in which case, however, the contour accuracy decreases.

In the direction of the shot 19 seen behind it connects to the target representation 13 a hard poured silicone layer 14 identical, and in conjunction with the outer layer 11 which enhances the "rubber effect." Primarily, however, this layer serves 14 To keep the target stable, ie to prevent the escape of the projectile backwards away from the shooter.

In the direction of the shot 19 seen behind it close to the hard silicone layer 14 now the layers of the silicone networks according to the invention 15 at. These absorb the kinetic energy of the penetrating projectile, since the shaft of the projectile (eg arrow shaft) is exposed to enormous frictional resistance and is steadily decelerated by the superposition of fine meshes. Also the permanently stable separation of the layers 15 is guaranteed. The resulting lateral tensile forces that are transmitted to the adjacent layers, as well as on the entire body of the target 20 act are extremely efficient.

In the direction of the shot 19 seen behind it closes and the layers of silicone nets 15 a filler 16 on, the z. B. may include silicone waste from production. As a layer 16 For example, a variety of geometrically diverse, mostly delicate silicone residues may be used, which due to their structure combine in a "spiderweb-like" manner, through thin strips and poured with fine, almost dust-like material of the same kind over the entire cross-sectional area. as soon as tensile forces build up, as they occur when projectiles enter, with the arrows specifically acting on high friction forces efficiently counteracted by the shaft length.The further the arrow through the kinetic energy, the speed, or arrow shape in the target 20 penetrates, the higher is the resistance opposed to it, as with a rubber band (the more you pull, the higher the retracting force). This makes it possible, with 20 eng.lips up to 60 eng.lips on the target of the invention 20 to shoot. The arrow removal is just "easy" in the upper area.

In the direction of the shot 19 seen behind it and close to the filler 16 second layers of silicone mesh 15 at.

In the direction of the shot 19 seen behind this connects to these second layers of silicone networks 15 a second soft molded silicone layer 17 at.

In the direction of the shot 19 seen behind it connects to this second silicone layer 17 third layers of silicone mesh 15 at.

In the direction of the shot 19 seen behind it connects to these third layers of silicone networks 15 an optional second layer filler 16 at.

In the direction of the shot 19 seen behind this close to the optional second layer filler 16 silicone profiles 18 with linear cavities. These silicone profiles 18 serve the gentler interception and the final stopping of all projectiles, such as arrows and even crossbow bolts. This effect is supported by the two in firing direction 19 seen before lying silicone layers 17 ,
