Definitions
- Socket tube for rifle grenade capable of retaining fragments of the bullet
- the present invention relates to a shotgun grenade and more precisely the casing tube which is placed at one end of the latter and allows it to be placed on the barrel of a rifle,
- the casing tube of a rifle grenade contains a bullet trap which, by stopping the latter, authorizes the shooting of the grenade by means of some ammunition and in particuller by means of a cartridge with a war bullet .
- the braking of the bullet by the plege generates metallic fragments (such as the pieces of the bullet jacket) and these fragments are ejected towards the shooter when the grenade leaves the barrel of the rifle.
- patent FR1599746 describes a bullet trap on which a plate of elastic plastic material is placed. The plate is perforated by the bullet and closes immediately after its passage, thus preventing the projection of the fragments on the shooter.
- Patent FR2517820 also describes a bullet trap for a rifle grenade which comprises a steel trap and a washer made of damping material arranged inside a support tube.
- the trap is closed by a nylon canvas cap which has the function of protecting the shooter against the fragments of the bullet and which is mounted tight or glued both on the case and on the trap.
- the subject of the invention is a socket tube for a grenade capable of being fired by a weapon by means of a bullet ammunition, tube containing on the one hand a bullet trap intended to stop the bullet and on the other hand a shutter of deformable material, intended to prevent the fragments produced during the impact of the bullet on the bullet trap from coming out of the sleeve tube, this tube is characterized in that the shutter is in abutment on a wall disposed between the shutter and the bullet trap, wall integral with the socket tube and substantially normal to the axis thereof, floor arranged at a distance from the bullet trap along the axis of the socket tube, a free space thus being left between the wall and the bullet trap.
- This arrangement avoids interference between the support wall of the shutter and the bullet trap during the impact of the bullet on the latter.
- the wall also ensuring the maintenance of the shutter which promotes its closure after the passage of the ball.
- the wall is secured to a support itself secured to the bushing tube and comprising a bore which maintains an external surface of the shutter.
- This arrangement facilitates the mounting of the shutter and improves its maintenance as well as its closure after being punctured by the bullet.
- the shutter has a bowl arranged opposite the wall.
- the shutter has notches regularly distributed on its external surface.
- the wall may have an opening with a diameter greater than the diameter of the ball.
- the shutter may have a rear part whose diameter is less than that of the bore of the support.
- the support has a bearing surface on which the shutter is supported and the wall is secured to a cover closing the bore and applying the shutter to the surface d 'support.
- the support includes a certain number of ori f ices allowing the passage of a part of the propellant gases generated by the ammunition to allow the arming of a rocket and it also includes a tightness ring adjusted to on the one hand on an external surface of the bullet trap and on the other hand on a cylindrical extension of the cover.
- the cylindrical extension of the cover constitutes a spacer which is supported on the bullet trap and makes it possible to keep the latter away from the wall.
- the support has a bottom on which the latter is supported and this bottom constitutes the wall.
- the bore of the support has an annular bead intended to ensure the axial maintenance of the shutter.
- the distance between the deformable shutter and the part of the bullet trap on which the bullet comes into contact with it will advantageously be greater than the total length of the bullet.
- FIG. 1 is a view in longitudinal section of a socket tube according to a first embodiment of the invention.
- FIG. 2 is a view in longitudinal section of a socket tube according to a second embodiment of the invention.
- FIG. 3 represents an alternative embodiment of the shutter support.
- FIG. 4 is a view in longitudinal section of a socket tube according to a third embodiment of the invention.
- FIG. 5a is a rear view of the support used in this third embodiment
- FIG. 5b is a front view of the shutter used in this third embodiment.
- a sleeve tube 1 is intended to be made integral with a rifle grenade (not shown). It comprises a rear part 2 which carries a stabilizing stabilizer 3 and has a bore 4 allowing it to be placed at the end of the barrel of a rifle.
- the socket tube also comprises a front part 5 which carries on its external surface a thread 6 which makes it possible to make it integral with a grenade of known type (for example anti-tank or anti-personnel).
- a grenade of known type for example anti-tank or anti-personnel.
- the front part 5 has a substantially cylindrical internal housing 7 inside which is disposed a bullet trap 8 of known type (that described by patent FR2543284).
- the internal housing 7 of the front part 5 is separated from the bore 4 of the rear part by a partition 9 whose central part 10 has a reduced thickness to facilitate the passage of the ball (such a structure is described by patent FR2605399 ).
- the bottom of the internal housing 7 constitutes a cavity 11 which is delimited on a rear side by the partition 9 and closed on the side of the bullet trap 8 by a support 12 in which a shutter 13 is arranged.
- the cavity 11 is filled with a propellant powder (not shown), ignited by the passage of the bullet, and which allows in a known way to increase the range of the grenade.
- the support 12 is a part having a symmetry of revolution.
- the bore 14 maintains an external surface of the shutter 13.
- the shutter is held in abutment on the wall 15 by an elastic washer 16 placed in an annular groove in the support 12.
- the shutter has a rear portion 29 whose diameter is slightly smaller (of the order of 1 to 2 mm) than that of the bore 14.
- the shutter is made here of elastomer of the polyurethane type of hardness 90 shores A.
- Another elastic material, composite or not, and having for example a hardness of between 80 shores A and 60 shores D could be adopted.
- the shutter has a bowl 25 of spherical profile arranged on the surface which comes to bear on the wall 15.
- This bowl allows the deformation of the shutter which facilitates the perforation of the latter by the bullet.
- the support is made of aluminum but another material could be used, for example a plastic material.
- the bullet trap 8 made of steel, has a conical opening 17 arranged at its rear face and which is intended to receive the bullet.
- the bullet trap 8 comprises a reduced diameter zone 19 at the level of which a spacer 20 made for example of aluminum is fitted.
- the spacer 20 is supported on one side on the bullet trap and on the other on the support 12 of the shutter 13.
- the bullet trap / spacer assembly is held in this support position on the support 12 by means of a nut 21 which is screwed into the bushing tube 1 and has a bore 22 ensuring the centering of the bullet trap 8 relative to the socket tube 1.
- the spacer 20 keeps the bullet trap away from the wall and therefore from the shutter.
- the distance between the bullet trap and the wall makes it possible to provide a free space 42 between these elements.
- the distance between the bullet trap and the shutter will be chosen so that the bullet trap 8 does not come into contact with the wall 15 during its deformation and also so that it remains between wall 15 and trap ball space sufficient to receive fragments of the ball.
- a distance of 5 to 10 mm can be adopted between the shutter and the rear of the bullet trap.
- the bullet When the grenade carrying the casing tube according to the invention is fired, the bullet first crosses the partition 9 at its thinned central part 10, it ignites the propellant composition placed in the cavity 11, then passes through the shutter 13 and its support 12.
- the wall 15 on which the shutter is held in abutment maintains the shutter relative to the sleeve tube during its perforation by the bullet.
- the ball thus achieves compression of the material constituting the shutter, material which is held axially by the wall.
- the wall 15 being disposed at a distance from the bullet trap, the deformation of the latter during the impact of the bullet does not degrade the shutter.
- the bore 14 firmly holds the external surface of the shutter which also promotes the closing of the latter.
- the shutter has a rear portion whose diameter is less than that of the bore 14. This difference in diameter allows a radial expansion of the material of the shutter during the impact of the bullet which facilitates the start of the perforation.
- FIG. 2 shows a second embodiment of the socket tube according to the invention and in which the wall 15 of the support 12 of the shutter 13 has an opening 24 of diameter greater than the diameter of the bullet,
- the shutter itself does not have a bowl facing the wall 15. During the perforation of the shutter, the material of the latter will deform through the opening 24.
- the support 12, by its bore 14 and its wall 15 ensures axial and radial maintenance of the shutter 13.
- the bullet trap 8 has a cylindrical surface 23 which ensures its centering relative to the socket tube 1 and also constitutes an axial stop maintained in abutment on an internal shoulder of the socket tube by the nut 21.
- This stop ensures the positioning of the bullet trap at a distance from the wall.
- FIG. 3 represents an alternative embodiment of the support 13 of the shutter, a variant which can be used in one or the other of the socket tubes described above.
- the bore 14 of the support 12 has an annular bead 26 which is intended to maintain the shutter in abutment on the wall 15 and which thus replaces the elastic washer 16 described above.
- the shutter 13 carries a front chamfer 27 and the support 12 a rear chamfer 28.
- the shutter 13 is force-fitted into the support 12 by means of a press.
- This implementation is facilitated by the presence of the chamfers 27, 28 and the bowl 25 which allows the elastic deformation of the shutter.
- the rigidity of holding the shutter by the support is thus improved and assembly is also facilitated.
- the distance between the bullet trap and the shutter will be given a particular value.
- the length of the spacer 20 will be chosen such that the distance D between the shutter 13 and the part of the bullet trap on which the bullet comes into contact with it is greater than or equal to the length of the ball.
- the bullets can have different lengths depending on their ballistic characteristics or their terminal efficiency.
- the length of the bullets available on the market is substantially between 18 mm and 23 mm.
- the shutter will be closed before this bullet comes to impact on the bullet trap, therefore before the first fragments generated by this impact are projected towards the rear of the casing tube. This increases the efficiency of the socket tube according to the invention.
- the partition 9 may possibly be removed, the shutter carried by the support will then constitute a sealing means closing the front part 5 of the socket tube. In the latter case, it is possible to glue the shutter 13 on a wall 15 obtained directly from machining with the socket tube.
- FIG. 4 describes a third embodiment of a socket tube according to the invention. This particular embodiment makes it possible to effectively retain the fragments of the bullet while allowing borrowing of the propellant gases generated by the ammunition to ensure the arming of a rocket.
- patent FR2567639 describes a grenade rocket mechanism which uses propellant gases. This mechanism comprises an annular lock which immobilizes a striker, this lock moves under the effect of the pressure of the gases and releases the striker.
- the socket tube according to this third embodiment therefore comprises a support 12 which is made integral with the socket tube 1 by threading. As in the previous variants, this support has a bore 14 which maintains an external surface of the shutter 13. The shutter is applied by a cover 33 against a bearing surface 31 secured to the support 12.
- the bearing surface 31 is pierced with an opening 32 of diameter greater than that of the ball.
- the cover 33 is made integral with the support 12 by threading.
- the wall 15 is carried by the cover 33 which closes the bore 14 and applies the shutter 13 against the bearing surface 31.
- the cover 33 has a cylindrical extension 34 which constitutes a spacer on which the bullet trap 8 comes to bear. This spacer keeps the bullet trap 8 away from the wall 15 and thus provides a free space 42 between these elements.
- the bullet trap is held in this support position on the cover 33 by means of a nut 21 which is screwed into the socket tube 1 and has a bore 22 ensuring the centering of the bullet trap 8 relative to the socket tube 1.
- the bullet trap 8 is made of steel and has a conical opening 1 7 arranged at its rear face and which is intended to receive the bullet.
- the distance between the bullet trap and the shutter will be chosen so that the bullet trap 8 does not come into contact with the wall 15 during its deformation and also so that it remains between wall 15 and trap bullet sufficient volume space to receive fragments of the bullet.
- a plastic sealing ring 35 is fitted both to the external cylindrical surface of the bullet trap 8 and to an external surface of the cylindrical extension 34 of the cover 33.
- the support 12 also has at its rear part a chamber 36 which is intended to possibly receive a charge of propellant powder. This chamber communicates with the rear part 2 of the socket tube through an opening 37.
- the support 12 has four orifices 38, regularly distributed angularly (see FIG. 5a), and which are intended for. allow the passage of part of the propellant gases generated by the ammunition to the front part of the socket tube.
- a closing straw 40 is placed on the rear face of the support 12 and makes it possible to close the orifices 38 and the opening 37 which prevents moisture from entering the interior of the sleeve tube during the storage phases.
- the shutter 13 used in this particular embodiment comprises a bowl 25 intended to be placed opposite the wall 15.
- It also has four notches 41 arranged on its external cylindrical surface and regularly distributed angularly (see FIG. 5b).
- the operation of the device is analogous to the operation described above. Note however that the holes 38 and the channels 39 allow the arming of the grenade rocket by borrowing gas.
- the ring 35 prevents a return of the propellant gases towards the shutter 13, thus the fragments of the bullet are retained by the shutter and remain inside the free space 42 delimited by the cylindrical extension 34 of the cover 33.
