Abstract

2D or 3D target object (1) for projectiles, in particular for bow, crossbow or dart arrows, which consists of a plurality of successively arranged material layers (4), characterized in that the 2D or 3D target object of material layers (3) crosslinked PE foam and made of material layers (4) made of cross-linked EVA foam.

Description

The The invention relates to a 2D or 3D target object for projectiles, especially for bow, crossbow or darts, the consists of several layers of material arranged one behind the other.

From the DE 25 57 153 A1 is a target, in particular for archery known, which consists of a plurality of superimposed membranes of lamellar plastic material and a plurality of interposed between the membranes and holding them at a distance intermediate layers of elastic and porous material, wherein the lamellae formed resilient and tear-resistant and of a pierced on the target arrow pierceable and the elastic and porous intermediate layers are also pierced by an arrow.

The DE 78 26 821 U1 describes a target made of a thermoplastic flexible foam.

From the DE 38 01 331 C2 is eiane target archery known, which consists at least partially of stratified foam, wherein foam strips are arranged and / or wound in a ring. The core of the target is interchangeable.

A 2D or 3D target object for projectiles, in particular for bow, crossbow or darts is from the DE 20 2007 009 864 U1 known. The target object consists of a plurality of successively arranged layers of at least one reticulated element of elastically deformable silicone material and / or elastomers, such as. B. synthetic or natural rubber.

Problematic is in such targets that they possible by different target groups, be it children or adults, Beginners or competitive athletes, to be used and accordingly also suitable for different arrows have to be. You must be both on the target object shot arrow give as well as a simple as possible Allow pulling the shot arrow, leaving deform the target object as far as possible after dragging the arrow should.

task The invention is therefore a target object according to the Generate generic term that better meet these requirements is known as target objects.

These Task is solved in that the 2D or 3D target object made of material layers of cross-linked PE foam and consists of material layers of cross-linked EVA foam.

PE foam is polyethylene foam and EVA foam is ethylene-vinyl acetate copolymer foam.

It has shown in the invention that a so constructed Target object the various candidate arrows both sufficient Give hold as well as allow easy pulling of the arrows. Due to the arrangement of the individual material layers, their hardness and respective strength can be the characteristics of the target object to the respectively desired properties be adjusted. In addition, the expansion process in a form, whereby the production of inventive 3D target objects is much easier. Both printing as well as a mechanical processing of the foams is possible which allows virtually any color and shape design.

It is within the scope of the invention that the PE foam and the EVA foam chemically or peroxide crosslinked. It is preferred However, the peroxide crosslinking, because they better material properties can be achieved.

A preferred development of the invention is that the 2D or 3D target object has a replaceable core.

There In particular, competitive athletes essentially only the core of Target targets hit, it wears off the fastest. In order to not having to replace the entire target object, it is advantageous when the core is interchangeable.

In In this context, it is advantageous that the core itself stepped from the inside of the 2D or 3D target extended to the front and that the disk body of the 2D or 3D target object adapted to this core Form has.

This On the one hand provides a secure fit of the core in the 2D or 3D target object safe and it allows on the other hand by Press on the center of the core from the back of the 2D or 3D target object, gently remove the core around it to replace it with another nucleus.

It is inventively provided that the 2D or 3D target object circular, polygonal, in particular rectangular or designed as a figure.

Finally, it is also provided in the context of the invention that two U-shaped foot elements are provided for the 2D or 3D target object, the made of cross-linked PE foam and / or cross-linked EVA foam.

in the The scope of the invention is defined by the term "2D or 3D target object for projectiles "not only the actual target object, but also any device for catching bullets next to or behind the actual target object to understand, as well as at Such devices have the good penetration characteristics, as they in the target objects according to the invention with material layers made of cross-linked PE foam and with cross-linked material layers EVA foam present, can be used.

following is an embodiment of the invention with reference to drawings explained in more detail.

It demonstrate

1 an inventive 2D or 3D target object in plan view,

2 the 2D or 3D target object in sectioned side view.

The 1 and 2 show a 2D target object according to the invention 1 , which is designed as a target here. In the center of the disk body 3 is the core 2 arranged, which - like out 2 visible - extends stepwise from the back of the 2D target object towards the front. The disk body of the 2D target has a core 2 adapted shape, which allows for wear of a core 2 this by pressure from the back of the disk body 3 fro the core 2 from the disk body 3 squeeze out and get a new core 2 insert positively into the disk body. The core 2 is thus both firmly in the disk body 3 arranged as well as easily interchangeable.

The disk body and the core 2 consist of a plurality of (in the direction from the front to the back of the target object) superimposed material layers 4 made of cross-linked PE foam and of material layers of cross-linked EVA foam, which - as well as 2 visible - are arranged one above the other in different layer thickness, in order to achieve the desired penetration behavior for the arrows used and then hold them in position.
