Bullet collection butt partic. for small calibre guns

The invention relates to a ball catch, as described in the preamble of claim 1

There are already a variety of bullet holes for projectiles of firearms, especially for small caliber firearms known.

Usually, they consist of an on catch container, a front and a rear wall, two side walls and a floor for the projectiles, wherein the rear wall projects beyond the collecting container in the opposite direction from the ground and inclined in the direction of a front wall, so that in the direction of Front wall protrudes and includes a tapered angle, which is between 30 ° and 60 °. The disadvantage here is that causes a larger amount of collected in the collection projectiles upon impact of another projectile on the impact plate that part of the projectile already deposited in the catch on projectiles are thrown into the open.

The present invention has for its object to provide a bullet trap for projectiles, which ensures a safe collection of impacting on the impact plate projectiles and their permanent deposition even with a longer-lasting shooting operation

This object of the invention is solved by the features in claim 1. The advantage here is that by the displacement of the impact plate forming part of the rear wall or the impact plate with respect to the rear wall of the collecting container, that the projectiles that impinge on the impact plate and are deflected by the obliquely downwardly extending direction in the direction of the collecting container and slide along , on this projection or Impact hitting before they fall into the receptacle into and thereby reduce the remaining residual energy on impact so far, so that they practically collapse or fall into the receptacle without energy. This prevents projectiles that are already in the collecting container from coming in through the newly arriving projectiles

AT 000 494 Ul are thrown out of this, as has been the case when newly encountered projectiles with higher speeds or higher residual energy have been encountered.

Through the development according to claim 2 is achieved in an advantageous manner that in the adjoining the impact plate transition region can not remain projectiles, but due to the gravity slide down or can herunterkollem in the container, wherein the convex curvature of the transition region, the 'residual energy of the projectiles is reduced.

A secured deflection, even if the projectiles do not slide directly on the impact plate along, can also be achieved by the development according to claim 3.

In order to achieve a secure catching and a secured energy dissipation of the projectiles, the training or the depth of the transition surface between the rear wall of the collecting container and the impact container according to claim 4 is advantageous.

The Ansführungsvariante according to claim 5 has the advantage that when a separate impact plate is provided, even if it is not fully inserted, accidental leakage or passage of projectiles is effectively prevented.

An inexpensive and simple production of the ball catch can be achieved by the developments of the claims 6 to 9.

A reduction of the noise, during the shooting operation, can be achieved with advantage by the embodiments according to claims 10 or 11.

Another advantage is the further embodiment according to claim 12, as characterized the impact plate can be used to better highlight the target.

Finally, the emptying of the projectiles from the collecting container is facilitated by the embodiment according to claim 13

For a better understanding of the invention, this will be explained in more detail below with reference to the exemplary embodiment shown in the drawings

Show it:

Figure 1 shows an inventively designed ball catch in a simplified diagrammatic Dam division.

Figure 2 shows the ball trap of Figure 1 in end view, cut, according to the lines Π - Π in Fig. 1.

Fig. 3 cut another formation of the ball catch in the end view.

In Figs. 1 and 2, a ball catch 1 is shown, which is designed for collecting projectiles 2 of firearms, especially small caliber firearms. For this purpose, it has a collecting container 3, which has a front wall 4, a rear wall 5, two side walls 6, a bottom 7 and a cover plate 8. In the illustrated embodiment, the rear wall 5 has a subsequent thereto in the direction of an impact plate 9 projecting rear wall portion 10. The rear wall portion 10, the rear wall 5, the bottom 7, the front wall 4, the side walls 6 and the cover plate 8 are formed from a single material blank of flat material, such as sheet metal, and made by folding, between the rear wall portion 10 and the rear wall 5 a Transition surface 11 is provided, so that the rear wall part 10 and a rear wall part 10 or the rear wall 5 facing Stimende 12 of the impact plate 9 is offset from the rear wall 5 in the opposite direction of the front wall 4 by a distance 13, said transition surface 11 is inclined in the direction of the collecting container 3 and in the example, a sliding receiving tray 14 for the projectiles 2 can be arranged. The distance 13 may be between 2 mm and 20 mm, preferably 10 mm, depending on the thickness of the impact plate 9 used. This results in an offset of the end 12 of the impact plate 9 with respect to the rear wall 5 between 2 mm and 15 mm, but at least by 3 mm, in the direction away from the front wall 4 direction.

The transition surface 11 is formed in the region of the rear wall 5 by an enforcement of the sheet material. In any case, the side walls 6 protrude beyond the cover plate 8 into the side opposite the bottom 7 and have receiving slots 15, into which the impact plate 9 is inserted for holding. This receiving slot 15 is formed starting from the rear wall portion 10 in the direction of the cover plate 8 rising inclined. In order to fix the ball catch, in particular the side walls 6, formed from a one-piece sheet metal blank, the end edges 8 of the cover plate 8 can be crossed in the direction of the side walls 6

AT 000 494 Ul lowing projections 17 which pass through openings 18 in the side walls 6 and thus hold the position of the side walls 6 in their abutting the cover plate 8 position by bending or beading. This is of course also possible for the fixation of the front wall 4, the bottom 7, the rear wall 5 or the rear wall part 10.

It is essential that an upper edge 19 of the inclined transition surface 11 has a maximum distance 20 from the bottom 7, so that in the transition region between the impact plate 9 and the rear wall part 10 no projectiles 2 äblagem but, even if this without any energy in the field Top edge 19 impinge, simply fall by gravity as on a slide in the receptacle 3. If a projectile 2, as shown for example by an arrow 21, strikes a surface 22 of the impact plate 9, which may be made of plastic, such as polyamide or polyurethane, or by a metal plate of metallic or non-metallic material, the projectile 2 will slide due to the impact energy and by the inclination of the surface 22 of the impact plate 9 at an angle 23 between 30 ° and 60 ° with respect to the rear wall portion 10 and the rear wall 5, as indicated by a slightly wavy arrow 24, along the impact plate 9 in the direction of the transition surface 11 and meets there on the transition surface 11, as shown by an arrow 25

As a result of this impact on the transition surface 11 running almost perpendicularly or substantially perpendicularly to the impact plate 9, the residual energy still inherent in the projectile 2 is reduced and the projectile 2 collapses, as indicated schematically by the projectiles 2 at the transition surface 11 and falls into the collecting container 3 or the receiving tray 14th Preferably, the impact plate 9 is colored white throughout or at least provided with a white coated or painted surface 22.

Due to the fact that the energy of the projectile 2 is reduced, the energy of the projectile 2 attributable to the collecting container 3 is so small and in principle given only by the drop height of the transition surface 11 into the collecting container 3, or so greatly reduced that by the incident into the receptacle 3 projectiles 2 no longer there already projected from projectiles 2 can be thrown out of the receptacle 3.

Furthermore, it is also possible that the transition surface 11 consists not only of an inclined surface portion 26, but of a plurality of angularly spaced partial surfaces. It is also possible to form convex this transitional surface 11, wherein in each case the highest point of the curvature in the region of the upper edge 19, the largest distance 20 from the ground

AT 000 494 Ul, in order to prevent projectiles 2 can deposit there.

Furthermore, it can still be seen from FIG. 2 that one of the rear wall 5 facing end edge 27 of the cover plate 8 is arranged at a distance 28 from the rear wall 5 at a distance. As a result, a receiving slot 29 is formed between the end face 27 and the impact plate 9 or the rear wall 5, through which the projectiles 2 impinging on the impact plate 9 or the rear wall 5 can fall into the collecting container 3.

/

Furthermore, an upper edge 30 of the impact plate 9 projects beyond the rear wall 5 or the rear wall part 10 by a height 31 in the direction away from the bottom 7, so that, for example, even if, as shown in Fig. 2, a separate independent impact plate 9 is used and this is not pushed up to the stop in the receiving slots 15, unintentional passage of projectiles 2 through the ball catch is avoided.

In Fig. 3 it is further shown that in a bullet trap 1, the impact plate 9 may be integrally connected to the rear wall 5 and be formed by the rear wall 5 and on the transition surface 11 in the direction of the cover plate 8 and beyond this projecting rear wall portion 32 can. The angular position of this rear wall part 32 with respect to the rear wall 5 and the rest of the training of the ball catch 1 can according to the Ausführangsvariante, as shown in FIGS. 1 2, the same reference numerals are used for the same parts and reference is also made in this regard to the description of the embodiment according to FIGS. 1 and 2.

In this case, the ball catch 1 can be made only from a single, one-piece component or sheet metal blank.

Both in this case, when the rear wall portion 32 forms the impact plate 9 or a specially applied impact plate 9 of metallic materials, such as steel or hard aluminum or the like., Is present, the surface facing away from the surface 22 of the rear wall portion 32, as shown schematically by dashed lines Lines indicated, with a noise-insulating coating 33, such as Plastic, rubber, nonwovens, foams, etc., be provided to reduce the noise when hitting the projectile 2. Of course, it is also possible that the impact plate 9, regardless of whether it is integrally connected to the rear wall 5 or additionally inserted into the ball catch 1 from a composite component of several layers of thin metallic or

AT 000 494 Ul ceramic materials or even from different layers of knitted fabrics, fibers, fabrics made of fibers or filaments of natural or synthetic materials This allows on the one hand a higher dielectric strength of the impact plate 9 and optionally an additional noise reduction when hitting the projectile 2 at Shooting operation he aims to be.

Furthermore, in this embodiment variant, the transitional surface 11 is composed of a plurality of sub-surfaces 34 arranged at an angle to one another, as has already been mentioned as a variant in the description of FIG. 2.

Finally, for the sake of order, attention should be drawn to the fact that in the drawings individual components or assemblies are shown disproportionately and distorted to scale for a better understanding of the invention.

It is also possible to form individual features of the individual exemplary embodiments with other individual features of other exemplary embodiments or in each case alone the subject matter of independent inventions.
