Definitions

  • the present invention relates to locking and release device of a magazine of a firearm, preferably of the pistol type.
  • Automatic and semi-automatic magazine fed firearms include means for locking the magazine during use of the weapon.
  • the magazine In the case of a rifle or assault rifle, the magazine is generally placed in a magazine well placed in front of the trigger guard in the case of conventional FN FNC or AK47 type rifles or behind in the case of a type weapon. bullpup.
  • the magazine lock control is generally disposed in the frame and requires moving the hands to change magazine.
  • the magazine In the case of semi-automatic pistol-type handguns, the magazine is generally placed in the handle itself and it is locked by means of a push button which can be moved in translation perpendicular to the handle and to the barrel axis to unlock the magazine.
  • This magazine lock is placed near the normal position of the thumb when firing, so as to allow easy ejection of the empty magazine at the end of the firing sequence, and reloading without modifying the firing position of the hand engaged on the handle.
  • the speed of magazine change is further improved by the presence on the magazine board of a protuberance actuating a breech stop (or slide) holding the slide and / or the breech back after the last firing. cartridge. Stopping the breech back has the effect of indicating to the shooter that he has no more cartridge, and simplifies reloading, the breech being in position to reload a new cartridge from a new magazine.
  • this type of magazine lock has at least two drawbacks.
  • the position and type of movement by simply pressing the thumb can induce an untimely release of the magazine due to a false movement of the shooter, and on the other hand, the position of the thumb must be adapted to the right-handed or left-handed grip of the shooter.
  • One of the objectives of the present invention is therefore to provide a magazine lock reducing the probability of unwanted release of the magazine.
  • the magazine lock mechanism must allow ambidextrous use of the weapon concerned.
  • ambidextrous devices should allow release from one side, without inducing movement on the other side.
  • the activation button can be located under the palm or under the index finger of the opposite face, which could induce friction preventing easy release of the lock.
  • the present invention relates to a pistol magazine unlocking mechanism comprising at least one control button arranged on the side of a handle into which can be inserted a magazine, each control button being fixed to one end of a control lever controlling the rotation of a latch cam disposed at the front or rear of the handle said latch cam comprising a latch, cooperating in use with a stop surface disposed on the front or rear surface of the handle loader to lock or unlock said loader, at least one spring holding the lock cam in the loader locked position in the absence of pressure exerted on the control button.
  • the pistol magazine release mechanism of the invention includes at least one, or an appropriate combination of the following features:
  • the mechanism comprises two control buttons arranged to the right and left of the handle, each control button being fixed to one end of a control lever controlling the rotation of the locking cam, allowing the magazine to be unlocked by actuating the button right or left control;
  • Each control lever comprises a control lever lug bearing on a corresponding latch cam lug of the latch cam, the latch cam being rotated when one of the control buttons is actuated;
  • the mechanism comprises a latch cam return spring holding the latch cam in the locked position and two control lever springs holding the control levers in the locked position, so as to make the movement of the left and right control buttons independent of each other
  • the latch cam is located at the rear of the handle.
  • a second aspect of the invention relates to a pistol comprising a magazine unlocking mechanism according to the invention.
  • the pistol of the invention comprises a frame guiding a slide and a frame covering said frame, the latch cam axis being fixed to the frame.
  • the frame is metallic while the carcass is polymeric.
  • FIG. 1 represents an example of a pistol grip comprising a magazine lock according to the invention.
  • Figure 2 shows the pistol grip of Figure 1 in the unlocked position.
  • FIG. 3 shows a perspective view of an example of a magazine lock according to the invention.
  • FIG. 4 shows another perspective view of the example of the magazine lock of FIG. 3.
  • Figure 5 shows a sectional view of a magazine handle comprising a magazine lock according to the invention.
  • FIG. 6 represents an enlarged view of the zone 14 of FIG.
  • FIG. 7 represents an enlarged view of zone 14 of FIG.
  • the present invention relates to a magazine unlocking mechanism, in particular a magazine unlocking mechanism integrated into a semi-automatic pistol.
  • the loader lock control 2 is disposed on the side of the handle 1.
  • the unlocking control is obtained by moving this control 2 from the top to down, and not by lateral pressure on a push button. This makes it possible to prevent a poorly controlled pressure of the thumb from unlocking the magazine 3, despite a position of the control 2 at a position normally occupied by the shooter's thumb when using the weapon.
  • levers 4.5 are arranged at the ends of two levers 4.5. These levers not only make it possible to position the control buttons 2,9 in the place allowing the best ergonomics (distance between the back of the handle and the last phalanx of the thumb), but also to increase the travel necessary for unlocking the charger. A longer stroke reduces the likelihood of unwanted unlocking, while a shorter stroke improves ease of use.
  • the lock according to the invention comprises a control button on each side of the handle.
  • cam 8 rotating about an axis 1 January.
  • This cam 8 comprises a stop surface 13 cooperating with a corresponding stop surface 15 on the rear face of the loader 3.
  • the two control buttons 2.9 will move integrally.
  • This integral movement can pose reliability problems in the case where the button on the palm side of the shooter's hand is located at the base of the index finger, or under a part of the palm exerting strong pressure on the corresponding button.
  • the pressure of the palm or the base of the index finger could prevent the unlocking movement, or, worse, the return of the lock to the locked position. In this case, it could be difficult to reliably replace a new charger.
  • the two control levers 4,5 actuate the lock cam by simply pressing a control lever lug 10 on a lug 7 of the corresponding latch cam on the latch cam 8.
  • a latch cam spring 6 ensures the return of the latch cam 8 regardless of the button 2.9 actuated (i.e. left or right).
  • Two separate springs ensure the return of the two levers 4,5 independently. This variant therefore makes it possible to make the movement of the two independent.
  • the guiding function of the moving parts in general, and of the slide in particular is decoupled from the gripping function of the weapon by the use of a metal frame comprising rails on which the slide slides during the cycle of the weapon.
  • a frame comprising the handle supports this frame.
  • This handle includes a charger well in which the charger is inserted.
  • the axis of the latch cam 1 1 is fixed to the frame and not to the carcass, so as to improve the positioning of the loader head (and therefore the positioning of the cartridge to be loaded) relative to the slide to avoid reloading problems during the cycle of the weapon.
