Definitions

  • the invention relates to an improved grenade launcher.
  • a grenade launcher comprises a casing with a trigger mechanism actuated by a trigger; a cannon mounted on the carcass; a locking mechanism for locking and unlocking the barrel vis-à-vis the carcass; an opening mechanism to open the grenade launcher to load and extract the ammunition; a handguard for holding the grenade launcher and at the same time to actuate the aforesaid locking and opening mechanisms.
  • a grenade launcher also includes an extraction device that allows automatic extraction of an undrafted grenade or a grenade shell from the barrel chamber.
  • the automatic extraction mechanism can be integral with the bottom of the casing of the carcass, while the locking mechanism can for example be achieved by a bayonet-type lock which is actuated by the simple axial rotation of the barrel which is controlled for example by a simple longitudinal movement of the handguard .
  • the barrel is simply provided with locking lugs which are engaged in the bowl bottom of the casing of the grenade launcher. The rotation of the barrel allows the release of the locking pins of the bottom of the bowl.
  • a disadvantage of a grenade launcher of the longitudinal opening type is that the choice of ammunition is limited since the length of the grenades to be used is limited to about the opening distance of the grenade launcher.
  • a grenade launcher of this type is known, for example, from US / 2001/0042334 .
  • An advantage of this type of grenade launcher is to be able to use longer ammunition without being limited to the opening distance of the grenade launcher since the ammunition can be loaded and extracted laterally.
  • a disadvantage of this type of grenade launcher is the complexity of construction because of the complexity of the locking mechanism, requiring heavier achievements, and because of the complexity of the particular mechanisms of extraction of the sleeve, which is so restrictive that some manufacturers give up an automatic extraction and are content with an extraction manual.
  • the invention aims to avoid one or more of the aforementioned disadvantages and to provide a grenade launcher that is both of simple construction and allows the use of a munition of any length.
  • a grenade launcher which comprises a carcass, a barrel mounted on the carcass and an opening mechanism, characterized in that the opening mechanism comprises guiding means allowing to advance the cannon in the longitudinal direction of the carcass and the power to pivot in the lateral direction in the final part of its longitudinal movement.
  • the ammunition can be loaded and laterally extracted from the grenade launcher to use a munition of any length.
  • a grenade launcher according to the invention is characterized by an opening which is longitudinal in the first phase of the opening movement, which allows the application of simple opening and locking mechanisms.
  • the guide means are preferably such that they simultaneously make it possible to advance and pivot the barrel in the aforesaid end portion of the longitudinal movement of the barrel.
  • the barrel is mounted in a handguard which comprises at least two pads which are mounted one in the extension of the other in the longitudinal direction of the handguard and which are mounted in a manner sliding between two parallel longitudinal rails of the carcass, one of which is fixedly mounted on the handguard, while the other shoe is mounted in a pivotable manner laterally on the handguard.
  • the grenade launcher 1 as shown in the figures comprises a carcass 2; a tubular handguard 3 mounted on the carcass 2 and a barrel 4 rotatably and slidably housed in the handguard 3.
  • the carcass 2 comprises a sub-guard 5 and a bowl 6 into which one end of the barrel 4 can fit when the grenade launcher 1 is closed and whose bottom 7 can serve as a support for the ammunition which is loaded into the barrel.
  • chamber 8 formed in the nested end of the barrel 4.

  • Each end of the pivotable pad 14 is provided with a recess forming on each side a protrusion that can cooperate with a central pivoting abutment, respectively 22 and 23, each of the stops being housed in a recess 20 and limiting the pivoting stroke of the pad 14 about an average position as shown in FIG. figure 2 in which the shoe 14 is directed longitudinally relative to the longitudinal direction XX 'of the handguard 3 and between two extreme pivoting positions as shown in FIGS. figures 4 and 5 .
  • the fixed pad 13 comprises a straight portion 24 which is located at a distance from the pivotable pad 14 and a portion 25 formed by a tapered tapered end which extends in the longitudinal direction X-X 'of the handguard towards the pivotable pad 14.
  • the central pivot stop 22 is formed by an extension of the conical portion 25 of the fixed pad 13.
  • the handguard 3 is provided with a longitudinal limit stop 26 which can cooperate with a corresponding limit stop 27 on the carcass 2.
  • the longitudinal limit stops 26 and 27 are respectively positioned on the pivot 19 of the handguard 3 and the front end of the carcass 2.
  • stop 27 can be removed or raised so as to dismount the handguard 3 of the carcass 2.
  • the barrel 4 is slidably and rotatably mounted in the handguard 3.
  • An annular stop 28 at the mouth 18 of the barrel 4 limits the relative longitudinal movement of the barrel 4 in the handguard 3.
  • the barrel 4 is provided with a locking bayonet type 29 formed by tenons 30 which can engage in a known manner in the bowl 6 by interlocking this end of the barrel 4 in the bowl 6, followed by a rotation of the barrel 4 to close the chamber 8 of the barrel 4 and lock the barrel 4 on the carcass 2.
  • the grenade launcher 1 is provided with means 31 enabling the axial rotation of the barrel 4 to be actuated automatically by a longitudinal movement of the handguard 3 in order to be able to lock and unlock the barrel 4 when the handguard 3 is moved from one to the other. certain distance in the longitudinal direction relative to the carcass 2.
  • these means 31 are formed by a cleat through the wall of the handguard 3 to form an excrescence 32 of the handguard 3 which is guided in a oblique groove 33 outside the barrel 4, the groove 33 forming an angle with the longitudinal direction X-X '.
  • the barrel 4 is equipped with a brake 34 in the form of a tilting piece which, under the action of a spring 35, exerts a slight radial force on the sleeve of a grenade that would be present in the chamber 8 of the barrel 4, to ensure a slight hold of the sleeve in the chamber 8 when opening the grenade launcher.
  • a barrel plunger 36 is mounted in the handguard 3, the plunger 36 being controlled by a spring 37 retained by a pin 37 '.
  • the grenade launcher 1 may be provided with an automatic extraction device of the ammunition with an extractor 38 in the form of a pivotable hook which is mounted in the bowl 6 of the carcass 2.
