Definitions

  • the present invention relates to a rifle grenade comprising a tubular metal tail, one end of which is intended to be secured to the free end of a rifle barrel, a war head fixed, possibly detachably, to the another end of the tubular tail which is optionally provided with a tail, and a bullet trap provided with several solid cylindrical bodies each made of a material having a different hardness, this bullet trap being mounted in said tail and being provided with a shock absorber also mounted in this tail.
  • US patent ⁇ A ⁇ 3,726,036 discloses a rifle grenade of the type described above.
  • the rifle grenade according to US Pat. No. 3,726,036 comprises a tubular tail, the rear part of which contains a bullet trap coaxial with the tubular tail, this bullet trap being carried by a cap made of elastomeric material and by a connector, so that a free annular space is provided between the bullet trap and the inner wall of the tubular tail of the grenade.
  • the bullet trap includes a tubular member which may be of a relatively rigid material such as steel.
  • a cylindrical plug is provided in the rear part of a bore of the tubular element.
  • a cylindrical guide element is disposed at the front of the plug in the bore and a closure element is mounted at the front of the guide element in the anterior end of the bore.
  • the plug is preferably made of a relatively soft material such as plastic.
  • the guide preferably consists of a hard material having a high energy absorption coefficient.
  • This guide can for example be made of steel.
  • the closure part is preferably made of a relatively light material, such as aluminum, mild steel, copper, etc. or in a synthetic thermoplastic material having a high energy absorption coefficient.
  • the bullet trap described in US Pat. No. 3,726,036 has a complex structure and is made up of a multiplicity of parts.
  • a rifle grenade comprising a tubular tail in which is mounted a tubular piece carrying at one end a deceleration tube and at its other end a base plate.
  • the inside diameter of the deceleration tube is less than the caliber of the rifle with which the grenade is to be used.
  • the projectile is stopped by the bullet trap made up of the series of shielding discs alternating with shock absorbing discs.
  • the bullet trap with which the granade described in US Patent ⁇ A ⁇ 3,726,036 is equipped also has a high number of parts which have to be fixed in the tubular tail of the grenade. These pieces are at least seven in number.
  • the subject of the present invention is a rifle grenade equipped with a bullet trap of the type described in the first paragraph of this specification, this bullet trap being of very simple and safe construction and being universal, that is to say capable of retaining both normal lead-based bullets and steel core bullets of any caliber.
  • the bullet trap comprises a first solid cylindrical body made of a relatively soft material capable of decelerating and retaining a lead bullet, but incapable of retaining the steel core of a steel core bullet and a second solid cylindrical body made of hard material capable of retaining the steel core of a steel core ball, said first and second solid cylindrical bodies having a diameter which corresponds substantially to the internal diameter of the tail and being placed one against the other so that the first solid body is upstream of the second solid body, while the shock absorber is a deformable solid cylindrical body which is placed against the second solid cylindrical body and has a diameter less than the inside diameter of the tail, so as to be deformable in the radial direction.
  • this first solid cylindrical body is preferably simply crimped into the tail of the grenade and is advantageously made of a material chosen from aluminum, copper and their alloys, a shielding envelope being able to be provided at least on the lateral surface of this first body.
  • the second full hydraulic body of the bullet trap it is, according to a feature of the invention, in a material chosen from hard steels and ceramic materials.
  • the solid cylindrical body serving as a shock absorber is preferably placed between the second solid cylindrical body made of hard material of the bullet trap and a tail closure part mentioned above at its end opposite the end intended to be secured. to a rifle barrel, this closing piece which advantageously carries a striker for the war head mounted at said opposite end of the tail being held in place by screwing into the tapped end of the tail of the grenade.
  • upstream and “avai” denote respectively the end of the li , intended to be threaded on the barrel of a rifle the opposite end of the tail, on which is fixed, possibly removably, a war head.
  • the rifle grenade comprises a tubular tail 1 made of metal, for example steel, one end of which, namely the upstream end 2, is intended to be threaded onto the free end of the barrel.
  • a rifle (not shown), the opposite end of which, namely the downstream end 3, carries a war head 4 which can be fixed therein in a removable manner, as described below.
  • a tail 23 At the upstream end of the tail 1 is provided a tail 23.
  • a bullet trap designated, as a whole by the reference notation 5. This trap consists of three contiguous elements centered in the tail 1.
  • the first element shown separately in FIG. 2, consists of a solid cylindrical body 6, for example made of aluminum, copper or an alloy of these metals, which is advantageously provided with a peripheral shielding casing 7 and is fixed in the tail 1 for example by crimping.
  • the shielding casing 7 serves to prevent a bullet penetrating into the first element 6 through its upstream end, in a direction somewhat inclined with respect to the longitudinal axis of the tail 1, from damaging the internal wall of this tail.
  • this first elements 6 can be provided with grooves 8 which crush, during the installation of this first element 6 by pressing under pressure of the first element 6 in the shielding envelope 7, this element 6 being inserted into the inner wall of the tail.
  • the first element 6 is kept wedged in the tail 1, its diameter being moreover substantially equal, if not very slightly less than the inside diameter of the shielding envelope 7.
  • the second element of the bullet trap 5 also consists of a solid cylindrical body 11 made of a material harder than that of which the first element 1. This second element 11 are the height can be less than that of the first element 6 serves retaining the core of a steel core ball.
  • Steel core bullets used more and more frequently today, consist of a lead body surrounded by a copper sleeve and containing a hard steel core, which increases the penetration force of the ball into a target.
  • the bullet trap 5 can be considered as a universal bullet trap suitable for being used whatever the type of bullet used in the rifle for launching the grenade. The rifle user therefore does not have to worry about the type of bullet to be used for launching a grenade.
  • the second element 11 of the bullet trap 5 the diameter of which corresponds substantially to the internal diameter of the tail 1, has two opposite axial cavities 12 and 13, the cavity 13 serving to receive the stud 16 of a third element 14 of the trap.
  • the cavity 12 of the second element 11 is used to maintain the trajectory of the projectile during its impact in the center of the element 11.
  • This third element 14 contiguous to the downstream end of the second element 11 serves both to absorb the shock caused by the impact of a bullet stopped in the first element 6 and possibly in the second element 11 and to actuate a striker (which will be discussed later).
  • the third element 14 is constituted, in the embodiment shown, by a deformable solid body, for example made of copper, aluminum or an alloy of these metals, this body also having a cylindrical shape, the diameter of which is however less than the internal diameter of the tail 1.
  • a bullet enters the first element 6 and when, in the case of a steel core bullet, it strikes the second element 11, the shock caused by this bullet is absorbed by the third element 14 which deforms into being crushed, this deformation being possible thanks to the free annular space 15 surrounding this third element 14 inside the tubular tail 1.
  • This third element 14 is provided with a centering pin 16 which is inserted into the cavity 13 of the second element 11 during the mounting of the bullet trap in the tubular tail 1.
  • the third element 14 acting as a damper has, at its end opposite to that carrying the pin 16, a cavity 17 in which is housed the base 18 of a striker 19, the cylindrical body 20 of which extends through a closure member 21 of the upstream end of the tubular tail 1.
  • This closure member 21 is constituted by a threaded cylindrical disc, which is also advantageously made of metal and which is screwed into the downstream end 3 tapped at 22 of the tubular tail 1.
  • the war head 4 can be fixed, also by screwing, to the threaded downstream end of the tail 1.
  • different types of war heads can be used with the same tubular tail provided with the same bullet trap 5.
  • the closure member 21 instead of be screwed into the downstream end 3 of the tail 1, may consist of an optionally threaded cap covering the downstream end of the tail which can be threaded.
