Definitions

• the present invention relates to a device for locking and releasing a magazine of a firearm, preferably of the pistol type.
• Magazine-fed automatic and semi-automatic firearms include means for locking the magazine during use of the weapon.
• the magazine In the case of a rifle or an assault rifle, the magazine is generally arranged in a magazine well arranged in front of the trigger guard in the case of conventional rifles of the FN FNC or AK47 type or behind in the case of a weapon of the type bullpup.
• the magazine lock control is generally arranged in the carcass and requires moving the hands to change the magazine.
• the magazine In the case of pistol-type semi-automatic handguns, the magazine is generally arranged 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 close to the normal position of the thumb during 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 in grip on the the handle.
• the speed of magazine change is further improved by the presence on the magazine board of a protuberance actuating a breech (or slide) retainer holding the slide and/or the breech back after firing the last cartridge. Stopping the bolt backwards has the effect of indicating to the shooter that he no longer has a cartridge, and simplifies reloading, the bolt being in position to reload a new cartridge from a new magazine.
• this type of charger lock has at least two drawbacks.
• the position and the type of movement by simple pressure of 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 or left handed grip of the shooter.
• One of the objectives of the present invention is therefore to provide a magazine lock that reduces 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 may be 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 release mechanism comprising at least one control button arranged on the side of a handle in which a magazine can be inserted, each control button being fixed to one end of a control lever controlling translation of a latch cam arranged at the front or at the rear of the handle, said latch cam comprising a latch, cooperating in use with a stop surface arranged on the front or rear surface of the magazine to lock or unlock said magazine, at least one spring maintaining the locking cam in the locking position of the magazine in the absence of pressure exerted on the control button.
• the pistol magazine release mechanism of the invention comprises at least one, or an appropriate combination of the following characteristics: the mechanism comprises two control buttons arranged on the right and on the left of the handle, each control button being fixed to one end of a control lever controlling the translation of the locking cam, making it possible to unlock the loader by actuating the right or left control button;
• each control lever comprises a control lever lug resting on a corresponding latch cam lug of the latch cam, the latch cam being driven in translation when one of the control buttons is actuated;
• the mechanism includes a latch cam return spring maintaining the latch cam in the locked position and two control lever springs maintaining 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 lock cam is arranged at the rear of the handle.
• a second aspect of the invention relates to a gun comprising a magazine release mechanism according to the invention.
• the pistol of the invention comprises a frame guiding a slide and a carcass covering said frame, the bolt cam axis being fixed to the frame.
• the chassis is metallic while the carcass is polymeric.
• Figure 1 shows an example of a pistol grip comprising according to the invention.
• Figure 2 shows the pistol grip of Figure 1 in the unlocked position.
• Figure 3 shows a perspective view of an example of an alternative charger lock to the invention.
• Figure 4 shows another perspective view of the magazine latch example of Figure 3.
• Figure 5 shows a sectional view of a magazine handle comprising a magazine lock outside the invention.
• Figure 6 shows an enlarged view of the area 14 of the figure
• Figure 7 shows an enlarged view of the area 14 of the figure
• Figure 8 shows an example of a magazine lock mechanism according to the invention.
• Figure 9 shows a section of the device of the invention.
• the present invention relates to a magazine release mechanism, in particular a magazine release mechanism integrated into a semi-automatic pistol.
• This invention represents an alternative to the lock described in application PCT/EP2020/054624 by the same applicant.
• This application relates to the embodiments of Figures 3 to 7.
• the loader lock control 2 is arranged on the side of the handle 1. As shown in these figures, the unlocking control is obtained by moving this control 2 from top to the bottom, and not by side pressure on a push button. This makes it possible to prevent poorly controlled thumb pressure from unlocking the magazine 3, despite a position of the control 2 in 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 stroke necessary to unlock the charger. A longer stroke reduces the chances of unwanted unlocks, while a longer stroke short improves ease of use.
• Equivalent levers 4.5 are also present in the device of the invention shown in Figures 8 and 9.
• the lock according to the invention comprises a control button on each side of the handle.
• the rotating cam 8 has been replaced by a cam in translation 17, moving according to a movement represented by a double arrow in Figure 9 (the hidden parts of the lock cam 17 have been represented in dotted)
• the two control buttons 2.9 will move together.
• This united 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. Indeed, in this case, the pressure of the palm or the base of the index could prevent the unlocking movement, or, worse, the return of the lock to the locking position. In this case, it could be complicated to replace a new charger reliably.
• the two control levers 4.5 actuate the lock cam by simple pressing of a control lever lug 10, on a corresponding lock cam lug 7 on the lock cam 8.
• each control lever 4.5 actuates the lock 17 by pressing on a lug 19 located on said lock 17.
• the lock 17 is held in position by a spring 22, and each control lever is held independently of one another by springs 20.21.
• the function of guiding 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 carcass comprising the handle supports this frame.
• This grip includes a magazine well into which the magazine is inserted.
• the lock cam 17 is guided by a housing provided in a part 23 of the frame and not in the carcass, so as to improve the positioning of the head of the magazine (and therefore the positioning of the cartridge to be loaded) relative to the slide to avoid reloading issues when cycling the weapon.
