The invention relates to a training rifle grenade with one provided with a marking filling Projectile bomb made of plastic.

It is known that projectiles, which are not supposed to have a destructive effect, have an elastic projectile head Made of rubber or the like. To be provided and to use these projectiles again. With training grenades As is known, an elastic projectile head also serves to protect the projectile body against damage on impact. Finally, it is known to use a training grenade to identify the point of impact to be provided with a bullet hood made of plastic, which breaks on impact and a white one or contains colored marker fill. The projectile body consists of one with a filling provided hollow body made of metal or also made of plastic and is at its front edge screwed to the projectile hood containing the marking filling. The reusability of the projectile body is impaired because it is destroyed when the projectile hood is screwed together or jamming of the thread can occur on impact.

Practice rifle grenades with a projectile head made of rubber have the disadvantage that the projectiles rebound far from target and leave no impact mark.

The invention aims to avoid these two disadvantages and to connect these parts in such a way that that the projectile hoods made of plastic are easily attached, and replaced if necessary can be. This object is achieved according to the invention in that the upon impact Breaking bullet hood has a rear seat edge with a cylindrical fit and a wide frontal area, with which they are attached to a front cylindrical gradation of a reusable projectile body made of solid rubber is attached.

The plastic bullet cover, which breaks on impact, is not only left behind in the familiar one Way the desired impact marking, but also diminished by their resistance to destruction the impact of the rubber body, which reduces and shortens the rebound of the projectile body will. The plastic hood on the rubber body, which breaks on impact, has a wider, annular shape End face resiliently supported, so that part of the impact force even before the destruction of the Bullet hood is taken up by the rubber body, but no destruction of the rubber body occurs at its fit for the projectile hood because the parts are plugged together with a cylindrical fit Training rifle grenade

are. The one provided with the marking filling, at Impact rupturable projectile hood can be constructed at least in part from translucent plastic which shows the color of the marking filling from the outside. You can this way the individual shooters in a group each receive grenades with a marking filling of a certain color without needing additional identification of the projectile hoods, so that one can choose from the impact colors can see who shot.

In a further embodiment of the invention and for the simple and easy production of the grenade is at their equipment with a tail unit tail the latter expediently with a fluted approach in a central cylindrical recess of the rubber body inserted tightly.

The drawing shows as an example of the implementation of the invention, a rifle training grenade in Longitudinal section.

The exercise grenade has a reusable solid projectile body 1 made of rubber or similar elastic material, which is provided with a fit 2 at the front, on which a projectile hood 3 is seated. At the rear, the projectile body 1 has an axial cylindrical recess into which the front End of a tail unit tail 4 is inserted. The projectile hood 3 consists of translucent Plastic, e.g. B. made of cellulose acetate, polyethylene or the like. It contains an inert marking charge 5 and is at the back by a welded or

glued cover 6 completed. The hood is conical and provided at the rear with a cylindrical edge 3 a , which surrounds the fit 2 with a tight fit. The fit can be provided with one or more grooves so that the air trapped when the cap is put on can escape. The inert marking charge 5 can be made of colored powder, e.g. B. of talc, chalk, plaster or the like. Or consist of a colored paste or liquid. The color can be seen from the outside through the projectile hood made of translucent material.

The tail unit 4 consists of metal and is inserted into the recess of the projectile body 1 with a solid front part 4 a. This part is provided with a corrugation 7, which gives it a good hold in the projectile body. With the rear hollow part 4 b of the tail, the rifle grenade is placed on the shooting cup, not shown, of the firing weapon. A removable tail unit 8, which is held by two spring washers 9, sits on the rear end of the ao tail. The tail unit can be made of metal or plastic, e.g. B. consist of polyamide. In order to allow the air contained in the recess to escape when the tail pipe 4 is pushed into the projectile body 1, the recess is provided with one or more longitudinal grooves 10.

When the projectile hits the target, the projectile hood 3 deforms, with the in the Powder contained in the hood is initially pressed back against the flat front surface of the projectile body 1 will. It forms a shock-absorbing cushion that protects the reusable projectile body 1 from damage protects and reduces the rebound of the projectile from the target. Then the bullet hood bursts, so that the marking powder empties at the point of impact.

For a new shot, only the destroyed hood needs to be attached to the reusable projectile body to be replaced by a new one. The tail tube 4 is strong enough to withstand the impact. The more sensitive tail unit can easily be replaced with a new one if damaged. You only need to remove the rear spring ring 9 and put it on after the new one has been pushed on Put the tail unit back on.
