Definitions

  • the invention relates to an ejection device for a handgun. automatic or manual cycle fire, this firearm comprising a carcass, a barrel mounted on this carcass and having a shooting chamber and moving parts movable backwards relative to the carcass when moving parts, including a puller for drive a socket when reversing and a part of chamber closure, ejection device comprising an ejector mounted in this closure part.
  • the socket or uninitiated cartridge is extracted from the chamber using of the extractor which hooks the socket by its groove.
  • the tilting torque of the socket is created by the ejector which is fixed in the carcass or spring mounted in the cylinder head positioned generally diametrically opposed to the extractor, this which ensures an ejection trajectory of the socket located approximately in a plane perpendicular to the axis of the cannon.
  • this trajectory can be located in a direction more or less perpendicular to the axis of the barrel and on the right of the weapon.
  • the object of the invention is to avoid this drawback and ensure an ejection path compatible with left and right handed shooters with the same weapon without modification and therefore aims to obtain a weapon really ambidextrous.
  • the ejection device comprises a rocker ejector pivotally mounted about an axis transverse and comprising a guide part provided a passage for a socket, this ejection lever rocking between a lower position in which the entrance to its passage is in the trajectory of the socket when moving moving parts forward and a upper position, a pusher being provided for ejecting the bushing of the passage when the ejection lever is closer to its top position.
  • FR-A-1.538.586 describes a firearm whose device ejection system includes a pivoting sleeve deflector. This ejection device does not however include an ejector, the sockets being blown by the combustion gases against the deflector which deflects the socket towards the up and back by passing it through the outlet. The deflector has no passage guiding the socket.
  • the sleeve is guided forward in the device described in US-A-3,000,126, but this guidance is obtained by a groove in the wall of a part receiver forming an extension of the barrel.
  • the socket is extracted by an extractor which rotates it up to either in alignment with the groove.
  • the closing piece wears a finger which, when it returns to the front, push the bushing through this groove.
  • the pusher is preferably integral of a moving part.
  • the ejection device may include a spring pushing the ejection lever to its lower position.
  • Tilting to its upper position is caused by the moving parts when they go back, either by through the socket, either by direct contact.
  • Figures 1 to 8 show part of a shotgun gas and rotary lock comprising a carcass 1, a barrel 2 mounted on this carcass 1 and provided at the rear a shooting chamber 3 and a number of moving parts 4 which move backwards when backing up.
  • moving parts 4 are the slide 5 and the latch 6 provided at the front with a closing part 8 closing chamber 3 during firing and extractor 9.
  • the ejection device is of a construction different from that of conventional devices.
  • the closing part 8 does not have of a conventional ejector, but of an anterior face 11 able to move relatively, as it does no sufficient tilting torque of socket 10 during the recoil of the moving parts 4, but which it exerts on the sleeve 10 an axial force ensuring its maintenance.
  • This front face 11 is formed by the end of a part 12 which is movable in a cavity 13 in the closure part 8.
  • a spring 14 is mounted between the part 12 and the bottom of the cavity 13.
  • the closing part 8 comprises a stop rear 15, formed by a part of the bottom of the cavity 13, sufficient to allow support from the back of the socket during pressure build-up in chamber 3.
  • the sleeve 10 therefore remains held axially during the complete recoil of moving parts and their return to the front.
  • an ejection lever 16 is mounted at the rear of 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 socket 10.
  • This ejection lever 16 can switch between a lower position shown in Figure 3 and a upper position shown in Figures 1, 2 and 8.
  • the ejection lever 16 is pushed into its position lower by a spring 20, against 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 socket 10; this socket 10 which can pass below this part of guide 18 during recoil and therefore extraction of the socket 10.
  • An ejection tube 21 is also mounted on the carcass 1, above the barrel 2.
  • the ejection lever 16 abuts against the rear end of the ejection tube 21, a socket located in the passage 19 which can be ejected into this ejection tube 21.
  • the rear of the ejection tube 21 is provided with a device check valve 22, for example a valve, which prevents the socket 10 to return to the ejection lever 16 and to halt its operation, as shown in detail in Figure 9.
  • a device check valve 22 for example a valve, which prevents the socket 10 to return to the ejection lever 16 and to halt 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 membrane fragmented, etc.
  • This non-return device 22 can, in addition to preventing the back, protect the inner mechanism of the weapon from from the external environment and prevent the introduction of dust, sand, etc.
  • a brake 23 for brake the movement of the sleeve 10.
  • This brake is constituted by 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 a end of lever 24 enters inside passage 19.
  • a pusher 27 is mounted on slide 5. One end front of this pusher protrudes from the slide 5 and enters passage 19 when returning to before moving parts 4.
  • a slit can also be made in the part of guide 18 to allow the passage of part of the front end of the pusher 27.
  • the moving parts 4 are located in their forward 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 around the transverse axis 17 under the action of spring 20 to its lower position in which she presents the entrance to passage 19 in the trajectory of the sleeve 10 which is pulled into its position rear by extractor 9, as shown in figure 3.
  • This socket 10 returns forward, still driven by moving parts 4.
  • the ejection lever 16 with an adequate position of its axis of rotation 17 and of the walls of the workpiece guide 18 forming contact ramps, is pushed back upwards by the forward movement of the sleeve 10, as shown in FIG. 4.
  • the ejection lever 16 forces the bush 10 to pivot upwards until the combined action resulting from the geometries of the front of the extractor 9 and the anterior face 11 forming the ejector, ensures a clearance of the sleeve 10 from the extractor 9, as shown in FIG. 5.
  • the socket 10 is braked in the passage 19 of the rocker ejection 16 by the brake 23 exerting a lateral force on socket 10.
  • the ejection cycle can then be considered complete, socket 10 is driven out of the ejection lever 16 at a level of the emerging gun outward from it.
  • the ejection tube 21 allows, however, for reasons ergonomic to prolong the ejection, that is to say postpone the final ejection to the most appropriate place tear.
  • the succession of sockets 10 ensures by pushing each other behind the others, the drain flow of the ejection tube 21.
  • the remaining sockets 10 in the ejection tube 21 after stopping the shooting can simply be taken out of the gravity tube, lowering the weapon.
  • the socket 10 not yet ejected and the ejection lever 16 ensures a guide ceiling for the cartridge supplied, which greatly reduces the risk of misfeeding.
  • the ejection device does not only eject empty sockets, but also cartridges uninitiated.
  • the upward pivoting of the ejection lever 16 does not does not necessarily have to be caused by one of the pieces mobiles 4 above. It can be caused by another piece mobile or by any other part in relative movement vis-à-vis itself.
  • the barrel does not necessarily have to be fixed relative to the carcass.
  • the invention is for example applicable to a gun of the type with barrel movable towards the front which is the subject of a patent application filed in Belgium in the name of the applicant.
