    NOT DEADLY STOREY
    The invention relates to a non-fatal projectile (referred to in the literature "non-le- thal bullet" or "less lethal bullet") for firing by means of a firearm, which projectile on the barrel of a firearm - especially a handgun - attachable and by firing a common projectile is acceleratable. Such bullets are used for example by executive forces against persons. They should not inflict serious injury on those affected, but prevent them from committing criminal acts. Because situations requiring the use of such bullets may occur unexpectedly, such bullets must be fireable by firing a common projectile. This also makes it possible to use the weapon immediately after firing of such a shotgun for a shot with a common projectile.
    Such a non-fatal projectile is proposed in WO 01/11305. It consists of a mounted on the barrel hollow cylinder with a front fragile impact head, which can be filled with a liquid. The hollow cylinder is closed at the front by a projectile trap which, according to the description, consists of a material which can not be penetrated by the projectile. Furthermore, it can be seen from the description that the initial velocity Y · ♦ Mi · I »M *« μ «· 2
    of the projectile is 10 percent slower than the running exit speed of the projectile. This confirms what the undetectable project fears cause: it transmits almost all of the kinetic energy of the projectile to the projectile and the projectile is much too fast to be harmless. Apart from the spindle-shaped figure and the wings, even the fragile impact head can not change that. This floor is thus unsuitable for the purpose mentioned.
    Even with rifle grenades which can be fired by means of a projectile, in order to achieve a sufficient range of application, it is necessary to transmit as far as possible the entire kinetic energy of the projectile to the projectile, especially since the mass of a rifle grenade is a multiple of the mass of the projectile. From GB 2223833 A a rifle grenade is known, which contains a projectile trap, which transmits the kinetic energy of the projectile with an optimal time course practically in its entirety onto the grenade.
    In a projectile which can be used for the purpose described above, it is first of all important that its nature (shape and mass) does not cause any fatal injuries and, above all, that its impact speed is relatively low even at a small distance from the target. This is the problem underlying the present invention.
    According to the invention, the solution is that the projectile has a body, the interior of which contains a catching device for the projectile, which catching device consumes a considerable part of the kinetic energy of the projectile (in fact: converts into deformation energy and frictional heat) and only a fraction of that in kinetic Energy of the non-lethal projectile converts. It is thereby achieved that a relatively light projectile can still be fired with a velocity 3 φ φ φ φ φ φ * φ φ φφ φ φ φ φ φ φ φ φ φ φ φ that is still sufficient for the required range without passing through the Projectile deformed or even destroyed.
    For this purpose, the safety gear for consumption or for converting a major part of the kinetic energy of the projectile from at least one in the body over a distance in the longitudinal direction by overcoming frictional forces and plastically deformable by deformation forces plug. It is only through the combination of a sufficient friction path and the internal friction overcome by plastic deformation of the plug that a sufficient amount of kinetic energy of the projectile is consumed.
    In a practical embodiment, the catching device consists of a plug and a catching piece, wherein the rear part of the plug is a plug which can be plugged into the mouth of the barrel, and the front part of the plug forms a cylinder cooperating with the catching piece. The plug performs two functions. First, it forms a friction surface cooperating with the catch piece, which can be suitably dimensioned and designed for the purpose of energy consumption. Second, it is in the barrel and thus serves the attachment of the projectile in the mouth of the barrel. This has the advantage in comparison with externally attached to the barrel fasteners that the projectile can be fired by various weapons.
    In a particular embodiment, the front part of the plug is a hollow cylinder whose inner diameter is equal to or greater than the outer diameter of the pin. The hollow cylinder abuts an achsnormalen annular surface of the catching piece and forms because of its inner diameter at the transition to the rear pin of the plug a predetermined breaking point. When shearing the
    Hollow cylinder at the predetermined breaking point is consumed further kinetic energy of the projectile.
    In a preferred embodiment of the invention, the catching piece is a hollow cylinder, which has a centric, closed at its front and rear open blind hole. The catching piece is pressed into a likewise closed at the front and rear open blind bore of the projectile body over only a portion of its length, so that the catching piece over the remaining part of the length of the blind bore is force application displaced. In the blind hole of the catching piece of the pin after shearing at the predetermined breaking point by overcoming frictional forces can be inserted. The diameter of the blind hole is equal to or smaller than the diameter of the pin. Thus, two friction surfaces of considerable length are created: a first between the pin and the catching piece and a second between the catching piece and the body of the projectile. As a result, the friction length (the "braking distance") is doubled, so created a total considerable friction distance, given the length of the projectile.
    In a further development of the invention, the plug consists of a ductile material (preferably a thermoplastic) and has at its rear end a central recess from which, starting from the pin of the plug under the action of the impinging projectile is deformed. The deformation of the plug consumes additional kinetic energy. The projectile impinging on the central recess penetrates completely into the journal and deforms it into a tubular structure. Because of the large deformed volume of the pin, a lot of energy is consumed.
    In a further developed embodiment of the invention, the lengths of catching piece, plug, blind hole and blind hole are selected so that the heavy 5 5 * * * * * * * «« «··« · · «• * *» * · «· · · ······················································································································································································································································································· , In the case of the spherical outer contour of the projectile, this is the center of the sphere.
    The spherical outer contour solves a secondary problem: Since a transfer of the swirl of the projectile on the projectile, if at all, takes place only to a very small extent, a spin stabilization of the projectile is not given. For the use of wings (see WO 01/11305), the airspeed is insufficient. A missile of elongated shape would therefore "whine" in the air and could strike as a ricochet. Thanks to the spherical outer contour of the projectile, and especially in the central position of the center of gravity, the projectile can rotate in flight at will, so that it is uncertain with which point of its outer contour the projectile hits. The fact that the body of the projectile is surrounded by a soft shell of, for example, foam or other soft material, he does not need to be spherical (which reduces its weight) and the coat of soft material ensures that the target person no lethal injuries occur.
    To reduce the weight and better connection between the body of the projectile and the outer spherical sheath, the body may be made of plastic and having circumferentially extending ribs.
    This also facilitates the production of the jacket by molding. The production of the body made of plastic has the further advantage that it can give way upon expansion of the catching piece by penetration of the projectile. "
    Finally, in the context of the invention, two measures of safety of the target person serve: If the diameter of the spherical contour is greater than 4, preferably 5 cm, the projectile does not fit into the orbit of a target person, which prevents serious eye injuries. Furthermore, if it is ensured that the rear edge of the catching piece does not protrude beyond the contour of the body of the projectile, striking with the rear zone of the projectile can not cause any serious injuries.
    In the following the invention will be described and explained with reference to figures.
    They show:
    1 shows a longitudinal section through an embodiment of a projectile according to the invention in a first phase,
    Fig. 2: The same, in a second phase,
    Fig. 3: The same in a third phase.
    In Fig. 1, the projectile according to the invention is denoted by 1 and any gun 2. Of the latter, only the front part of a carriage 3 and a barrel 4 can be seen, in which a projectile 5 is already underway. Fig. 1 thus also represents the first movement phase.
    The projectile 1 according to the invention consists first of a body 7 and a shell 8. The body 7 is made of a lightweight metal or a solid plastic (for example, a thermoplastic) and has circumferentially extending ribs 9. To form the shell 8, he is from a surrounded by soft foam. The body 7 has a longitudinal central blind bore 10 which forms a bottom 11 at its front end. As can be seen, the blind bore extends over most of the length of the body 7. At its rear, open, end, the blind bore 10 has an extension 13 which terminates at a first shoulder 12.
    The safety device arranged inside the body consists of a catching piece 15 and a plug 22. The catching piece 15 is a circular cylinder with a blind hole 17 which ends in a bottom 18 in the front. The outer diameter of the cylinder has an excess of the inner diameter of the blind bore 10, so that it is displaceable only by overcoming the considerable frictional resistance in the longitudinal direction. At its rear edge The catching piece 15 has an outwardly projecting collar 16 and a rearwardly projecting collar 20. The collar 20 has the same or a slightly larger inner diameter than the blind hole 17 and goes over a second shoulder 19 in this over.
    The plug 22 is a pin 23 which merges into a hollow cylinder 24 vome. The transition 25 represents an all-round predetermined breaking point. The pin 23 is in the barrel and thus keeps the projectile 1 ready. The pin 23 has at its rear end a central recess 26 at which the projectile strikes with the consequences to be described below. The plug 22 is made of a ductile material which may be metallic or preferably a suitable tough and strong plastic.
    In the following the operation of the invention will be described with reference to all three figures.
    In Fig. 1, a shot has already been fired, the projectile 5 is in the barrel 4 and moves towards the plug 22. It will immediately push the pin 23 out of the barrel (unless it has already done the air column in front of the projectile 5) and exert on the pin 23 a force that pushes him into the blind hole 17. Since the hollow cylinder 24 of the plug 22 is supported on the second shoulder 19 of the catching piece 15, pin 23 and the hollow cylinder 24 are separated from each other at the predetermined breaking point 25. Since the inner diameter of the hollow cylinder 24 is equal to or larger than the diameter of the pin 23, the separation is carried out by shearing. Already this kinetic energy of the projectile is consumed. 8 ················································································.
    In Fig. 2, this has already been done and the pin 23 is pushed into the blind hole 17, wherein all the way 14 frictional forces are overcome. It can be seen that the hollow cylinder 24 has remained in the collar 20 of the catching piece 15. When the pin 23 has reached the bottom IS of the blind hole 17, causes the kinetic energy of the projectile 5, that now also the catching piece 15 is moved in the blind bore 10 of the body 7 until the catching piece 15 abuts the bottom 11 of the blind bore 10. Because the outer diameter of the catching piece 15 is slightly larger than the inner diameter of the blind bore 10, considerable frictional forces are to be overcome over the entire sliding path 21.
    The sliding path 21 is in Fig. 2, the distance between the front end of the catching piece 15 and the bottom 11 of the blind bore 10. The same distance 21 prevails also between the collar 16 of the catching piece 15 and the first shoulder 12 of the body 7. Once the catching piece Slideway 21 has traveled, the projectile 5 begins to penetrate into the central recess 26 of the pin 23. This is the main purpose of the central recess 26.
    In Fig. 3, the projectile 5 is already completely penetrated into the pin 23, while it has this under considerable deformation work to a tubular structure 23 * transformed. As can be seen, under the pressure acting radially outward, the wall of the catching piece 15 has also deformed outwards, which is possible without damaging it because of the material selection of the body 7. In addition, the center of gravity of the entire projectile with the safety gear and the projectile in the end position is approximately at the geometric center of the projectile 1. FIG. 3 also shows that in the end position of the catching piece 15, its collar 20 remains within the contour of the body 7 and therefore can not cause significant injury if the projectile encounters the target person with the rear zone in the image.
    Overall, energy is consumed in five successive phases: At the predetermined breaking point 25, by friction in the blind hole 17, once again by friction on the blind bore 10, by deformation of the wall of the catching piece 15 and finally by deformation of the pin 23. This can at relative low mass of the projectile (thereby the desired lower impact energy) and a high-energy projectile the majority of the kinetic energy of the projectile in frictional heat and deformation work to be converted. In the case of a smaller or slower projectile, the second friction, between the catching piece 15 and the body 7, can be dispensed with within the scope of the invention.
