Definitions

  • the invention relates to an ejection device for a firearm with an automatic or manual cycle, this firearm comprising a carcass, a barrel mounted on this carcass and having a firing chamber and movable parts displaceable rearward relative to to the carcass during recoil, the moving parts comprising an extractor for driving a socket during recoil and a closing part of the chamber, the ejection device comprising an ejector mounted in this closing part.
  • the socket or the uninitiated cartridge is extracted from the chamber by means of the extractor which hooks the socket by its groove.
  • a tilting torque of the sleeve is created by the ejector which is fixed in the carcass or mounted on a spring in the cylinder head positioned generally in diametrical opposition to the extractor, which ensures an ejection path of the socket located approximately in a plane perpendicular to the axis of the barrel.
  • this trajectory is generally located in a direction more or less perpendicular to the axis of the barrel and to the right of the weapon.
  • the ejection trajectory can be located between the vertical and the left to make the weapon more compatible with the left-handed shooter.
  • the invention aims to avoid this drawback and to ensure an ejection trajectory compatible with left and right handed shooters with the same weapon without modification and therefore aims to obtain a truly ambidextrous weapon.
  • the ejection device comprises an ejection lever pivotally mounted about a transverse axis and comprising a guide part provided with a passage for a socket, this ejection lever rocking between a lower position in which the entry of its passage is in the trajectory of the socket when the moving parts return to the front and a higher position, a pusher being provided to eject the socket from the passage when the ejection lever approaches its upper position.
  • the pusher is secured to a movable part.
  • the ejection device can comprise a spring pushing the ejection lever towards its lower position.
  • the tilting to its upper position is caused by the moving parts when they return forward, either through the socket, or by direct contact.
  • FIGS. 1 to 8 show a part of a rifle with gas tap and rotary locking comprising a carcass 1, a barrel 2 mounted on this carcass 1 and provided at the rear with a shooting chamber 3 and a number of parts mobiles 4 which move backwards during recoil.
  • moving parts 4 are the slide 5 and the latch 6 provided at the front with a closing part 8 closing the chamber 3 during firing and the extractor 9.
  • the ejection device is of a construction different from that of conventional devices.
  • the closing part 8 does not have a conventional ejector, but an anterior face 11 which can move relatively, such that it does not provide sufficient tilting torque for the sleeve 10 during recoil moving parts 4, but that it exerts on the sleeve 10 an axial force ensuring its maintenance.
  • This front face 11 is constituted by the end of a part 12 which is movable in a cavity 13 in the closing part 8.
  • a spring 14 is mounted between the part 12 and the bottom of the cavity 13.
  • the closing part 8 has a rear stop 15, formed by a part of the bottom of the cavity 13, sufficient to allow support from the rear of the socket during pressure build-up in chamber 3.
  • the sleeve 10 therefore remains held axially during the complete retraction of the moving parts and their return forward.
  • an ejection lever 16 is mounted at the rear of the chamber 3 which pivots relative to the carcass 1 around a transverse axis 17.
  • the ejection lever 16 comprises a guide part 18 crossed by a passage 19 for the sleeve 10.
  • This ejection lever 16 can switch between a lower position shown in FIG. 3 and an upper position shown in FIGS. 1, 2 and 8.
  • the ejection lever 16 is pushed into its lower position by a spring 20, against a part of the carcass 1 forming a stop.
  • the guide portion 18 In the upper position, the guide portion 18 is located above the path of the sleeve 10; this socket 10 being able to pass below this guide portion 18 during the retraction and therefore of the extraction of the socket 10.
  • An ejection tube 21 is moreover mounted on the carcass 1, above the barrel 2.
  • the ejection lever 16 abuts against the rear end of the ejection tube 21, a sleeve located in the passage 19 being able to be ejected in this ejection tube 21.
  • the rear of the ejection tube 21 is provided with a non-return device 22, for example a valve, which prevents the socket 10 from returning to the ejection lever 16 and from stopping its operation, as shown in detail in figure 9.
  • a non-return device 22 for example a valve, which prevents the socket 10 from returning to the ejection lever 16 and from stopping its operation, as shown in detail in figure 9.
  • This non-return device 22 can be produced simply by a deformable part, leaf spring or fragmented membrane, etc.
  • This non-return device 22 can, in addition to preventing the return, protect the internal mechanism of the weapon from the external environment and prevent the introduction of dust, sand, etc.
  • a brake 23 for braking the movement of the sleeve 10.
  • This brake consists of a lever 24 pivotally mounted on the guide part 18 and pushed by a spring 25 in a position in which a shoe 26 mounted on one end of the lever 24 penetrates inside the passage 19.
  • a pusher 27 is mounted on the slide 5. A front end of this pusher projects with respect to the slide 5 and enters the passage 19 when the moving parts 4 return to the front.
  • a slot can also be made in the guide part 18 to allow the passage of part of the front end of the pusher 27.
  • the moving parts 4 are in their front position and the ejection lever 16 is held in its upper position against the tube ejection 21, against the spring 20, by a stop 28 located on one of the moving parts 4 (see Figures 1 and 2).
  • the ejection lever 16 pivots about the transverse axis 17 under the action of the spring 20 to its lower position in which it presents the entry of the passage 19 in the trajectory of the sleeve 10 which is pulled into its rear position by the extractor 9, as shown in FIG. 3.
  • This socket 10 returns forward, still driven by moving parts 4.
  • the ejection lever 16 by means of an adequate position of its axis of rotation 17 and the walls of the guide piece 18 forming contact ramps, is pushed up by the forward movement of the sleeve 10, such as shown in Figure 4.
  • the ejection lever 16 forces the bush 10 to pivot up until the combined action resulting from the geometries of the front of the extractor 9 and of the front face 11 forming the ejector, provides clearance from the sleeve 10 of the extractor 9, as shown in FIG. 5.
  • the sleeve 10 is braked in the passage 19 of the ejection lever 16 by the brake 23 exerting a lateral force on the sleeve 10.
  • the sleeve 10 is driven from the ejection lever 16 to a level with the through weapon outward from it.
  • the ejection tube 21 however makes it possible, for ergonomic reasons, to prolong the ejection, that is to say to postpone the final ejection to the most appropriate place of the weapon.
  • the succession of sockets 10 ensures by pushing one behind the other, the emptying flow of the ejection tube 21.
  • the sockets 10 remaining in the ejection tube 21 after the firing stop can be simply removed from the tube by gravity, lowering the weapon.
  • the sleeve 10 not yet ejected and the ejection lever 16 provide a guide ceiling for the cartridge supplied, which greatly reduces the risk of misfeed.
  • the ejection device does not only eject empty sockets, but also uninitiated cartridges.
  • the upward pivoting of the ejection lever 16 does not necessarily have to be caused by one of the above-mentioned moving parts 4. It can be caused by another moving part or by any other moving part relative to itself.
  • the barrel does not necessarily have to be fixed relative to the carcass.
  • the invention is for example applicable to a firearm of the type with a barrel movable forwards which is the subject of a patent application filed in Belgium in the name of the applicant.
