Definitions

  • the present invention relates to an automatic or semi-automatic firearm comprising a carcass, a cartridge magazine removable in the carcass, a movable cartridge lifting piston in the magazine, a spring in the magazine for raising the lifting piston by pressure.
  • permanent a temporary store retention in the carcass activated by engagement in a notch arranged in the wall of the latter, a manual command to deactivate the store retention and release the latter at will, a barrel near the carcass, a chamber fire following the barrel and intended to receive a cartridge from the magazine, a cylinder head movable back and forth on the carcass and comprising means for, after each shot of a cartridge, extract from the fire chamber and during its retraction the cartridge case drawn, and move and insert another cartridge during its return from the magazine to the fire chamber, and this until the last re magazine cartridge, at the end of the elevation stroke of the cartridge lift piston.
  • breech stopper a mechanism suitable for retaining the breech open, in the back position, after firing the last cartridge from the magazine.
  • the retention of the cartridge magazine is constituted by a lever having a stop coming to engage, under the permanent pressure of a spring, in a retaining notch of the magazine wall and this at the arrival of the magazine in place provided in the carcass.
  • the command to deactivate the magazine retainer is generally constituted by a simple extension of the lever of this retainer outside the carcass and having at its end a grip for the thumb or forefinger of the shooter, in particular when this control is placed in the immediate environment of the trigger of the weapon, at the top of the butt, for reasons of ergonomics.
  • the stop of the latter is disengaged from the notch of the magazine, and the latter is released and can be removed from the carcass.
  • the shooter can thus at any time extract the magazine from his weapon, not only for checking the number of cartridges remaining or to replace it with another one, but also for security reasons, such as for example in the event of a firing stop or in the event of the weapon being engaged.
  • the breech stop is a return spring lever comprising a stop intended to engage in a retaining notch of the movable breech to keep the latter open in the retracted position.
  • the engagement of the stop in the retaining notch of the cylinder head is conditioned on the one hand and firstly by application of the thrust of the cartridge lifting piston on the cylinder head retainer after chambering of the last cartridge of the magazine in the fire chamber, and secondly and in a second step by penetration of this stop, and under the effect of this thrust, in the retaining notch of the movable breech, a little before the end of the recoil movement of the latter following the firing of the last cartridge.
  • the fact that the bolt remains open in the recoil position avoids the shooter having to count the shots to know when he reaches the end of the cartridge magazine, allows in shooting range the visual verification to distance that the weapon is quite empty and out of function, and also avoids the shooter being with the breech turned down and the weapon ready to fire on an empty fire chamber, awkward situation in precision shooting and certainly delicate in combat.
  • the fact that the breech remains open can contribute to the cooling of the barrel.
  • the shooter moves the bolt a little further until the end of its reversing stroke to release the stop of the bolt retainer from the retaining notch thereof, which s 'Erased under the effect of the return spring, and lets the bolt start again to introduce the first cartridge from this magazine into the fire chamber, the weapon being thus again ready to fire.
  • means are provided so that the installation of a new magazine triggers the return of the bolt which remains open after the firing of the last cartridge in the magazine previous, and thus causes the chambering of the first cartridge of this new store.
  • the shooter is thus freed from the need to manipulate the breech to chamber this first cartridge, and he only has to take care of deactivating the retention of the empty magazine before replacing it with a new magazine.
  • the object of the invention is to further minimize the handicaps inherent in the manipulations required by the operations of changing the magazine of cartridges of a firearm and, thereby, to increase the firepower of this weapon.
  • the weapon according to the invention is characterized in that it comprises, in addition to the manual control for deactivating the retention of the cartridge magazine, an ejection device automatic of the latter out of the carcass comprising a magazine retaining actuation finger associated with the cartridge lifting piston, linked to the height movement of the latter and placed in a position provided to meet and deactivate the magazine retention under the pressure of a spring as soon as possible during the movement of the last cartridge of the magazine by the movable cylinder head and before the arrival of the cartridge lifting piston at the end of the elevation stroke, and an arming spring whose action, used and intended to drive the magazine out of the carcass, is released by disabling the store retainer.
  • the shooter is freed from the need to manipulate the command to deactivate the retention of an empty magazine before being able to replace it, since the latter is automatically ejected during the movement of its last cartridge by the movable bolt, during the return of the latter following the firing of the penultimate cartridge.
  • the last cartridge of the ejected magazine being introduced into the fire chamber by the movable breech, this means that during the introduction of the new magazine, a cartridge is chambered and the weapon ready to fire with it.
  • a weapon according to the invention may be desirable for a weapon according to the invention to have a breech that remains open in the retracted position after the last cartridge in the magazine has been fired, for a safety reason already mentioned. We may also wish this arrangement to facilitate cooling of the barrel.
  • the design of the automatic cartridge magazine ejection device makes it possible to meet this desire without requiring any particular appropriation of the structure and operation of the cylinder head retainer.
  • the breech retainer is controlled by soliciting a stop of the cartridge-raising piston during the latter's arrival at the end of its travel; or the actuating finger of the magazine retainer of the automatic ejection device according to the invention is independent of this stop.
  • stop and finger being necessarily distant from each other, it follows that only the magnitude of the gap which separates them must be appropriate to ensure the triggering of their functions according to a precise sequence, as will be shown in the description which follows.
  • Figures 1, 2 and 3 are three partial profile views, in partial section, of the first embodiment shown respectively in three different phases of its operation.
  • Figures 4, 5 and 6 are three partial sections along the same cutting axes I-I and respective of Figures 1, 2 and 3.
  • Figures 7, 8 and 9 are three partial profile views, in partial section, of the second embodiment shown respectively in three different phases of its operation.
  • FIGS 10 and 11 are two partial sections of the variant shown respectively in two different phases of its operation.
  • Figures 12, 13 and 14 are three partial profile views, in partial section, of the third embodiment shown respectively in three different phases of its operation.
  • FIG. 15 is a partial top view of the third embodiment, according to arrow f in FIG. 12.
  • Figure 16 is a side view of a part of the third embodiment.
  • the firearm represented by the six figures 1 to 6 of the first embodiment is a semi-automatic pistol operating without a breech retainer, but it is obvious that its inventive characters are applicable to any other type of weapon automatic or semi-automatic, whether or not fitted with a cylinder head retainer.
  • This weapon comprises a carcass 1 forming a butt 2, a trigger guard 3 of a trigger 4 and a movable breech 6.
  • the cartridge magazine 8 comprises a cartridge lifting piston 19 subjected to the permanent pressure of a compression spring 20 bearing on the bottom of said magazine.
  • Cylinder head 6, movable back and forth on the carcass 1 comprises the usual means for, after each shot of a cartridge, extract from the fire chamber and during its recoil the socket of the fired cartridge, and move and then introduce, during its return, another cartridge from the magazine 8 to the fire chamber 10, and this up to the last cartridge, at the end of the height stroke of the lifting piston 19.
  • a support ramp 23 of the cartridge emerging from the magazine 8 and a front wall 24 of the breech 6 intended to intercept this cartridge and to transfer it to the fire chamber 10 after the breech 6 has retreated following firing and during its return. From the front wall 24 opens the firing pin of the cartridge, not shown.
  • this automatic ejection device from the cartridge magazine 8, illustrated by FIGS. 1 to 6, is as follows: In the phase represented by FIGS. 1 and 4, the gun is ready to fire the penultimate cartridge 11, already introduced into the fire chamber 10, and the last cartridge 12 of the magazine 8 is pressed by the lifting piston 19 and under the pressure of the spring 20 against the ramp 23 of the movable yoke 6.
  • the phase represented by FIGS. 2 and 5, which is consecutive to the firing of the penultimate cartridge 11, is that during which the last cartridge 12 is moved and being introduced into the fire chamber 10, by return from the cylinder head 6, just after the finger 25 of the cartridge lifting piston 19 meets the tooth 16 of the retainer 13 of the cartridge magazine 8, the latter still being retained by this tooth 16. It is noted here in passing that the inclination of the active end of the wedge-shaped finger 25 is identical to that of the face of the tooth 16 urged by this finger. But this is not essential and contact can be made on an angle or on a round of tooth 16.
  • the spring 20 is still armed on a stroke in residual height and it therefore pushes and by reaction down the cartridge magazine 8.
  • the relative positions of the finger 25 of the lifting piston and the retainer 17 of the magazine, as well as the ratio of the forces of the springs 18 and 20 are determined so that the magazine 8 is released from its retention by the finger 25 a little before the end of the height stroke of the cartridge lifting piston 19 and while the latter is still in contact with the cartridge 12, during the transfer of the latter.
  • the retainer 13 is again armed by its spring 18, ready to retain a new cartridge magazine, while the last cartridge 12 is chambered and ready to be drawn.
  • the chambering of the first cartridge of the new magazine is then done automatically after firing the cartridge 12, on the return of the movable cylinder head 6, without that there is a need to manipulate it.
  • the weapon shown here by way of example is also a semi-automatic pistol, but which has been chosen for its differences in structure to bring out the versatility of the invention.
  • the differences in the structure of the weapon here relate, in addition to the presence of a bolt retainer, to the conformation of the retainer of the cartridge magazine and of the cartridge lifting piston.
  • the carcass 27 comprises a breech retainer 28 in the form of a lever articulated on a pivot and having at its end a stop 30 intended to block the movable breech 60 in the retracted position by engagement in a notch of that -ci which is here formed by the rise of the ramp 31 forming the front closure wall 32 of this movable yoke.
  • the breech retainer 28 In the intermediate position, between the pivot of the retainer 28 and the stop 30, the breech retainer 28 has a stop 33 arranged in the path of a plunger 34 integral with the cartridge lift piston 190 to be urged by the thrust of the latter, under the effect of its lifting spring 20, after chambering the last cartridge 12 of the magazine, against a return spring 35.
  • a stop 36, integral with the carcass 27, defines the position non-active rest of the cylinder head retainer 28.
  • the retention of the cartridge magazine 80 which here bears the reference 130, is a lever articulated on the carcass 27, activated by a compression spring 180, and having a retaining tooth 160 intended to snap under the thrust of said spring, in a retaining notch 170 of the cartridge store 80.
  • the manual control of this retainer 130 is constituted here by an extension 150 of this retainer having a grip for the shooter's finger.
  • the automatic cartridge magazine ejection device 80 here comprises a finger 250 for actuating the retainer 130 of the cartridge magazine mounted movable by translation in the cartridge lifting piston 190, in the transverse direction thereof and pressed elastically by a compression spring 37 against the wall of the cartridge magazine 80.
  • This wall has a hole 38, placed opposite the tooth 160 of the retainer 130 in the immediate environment of the retainer notch 170 to allow passage of the finger 250 d actuation of the retainer 130 at the arrival of this finger at this hole.
  • the cartridge magazine 80 furthermore has here a projecting lateral support 39 intended to be urged by the pushing of a spring 40 during the introduction of said magazine into the carcass 27 and before the activation of the retainer 130 of the latter, the active end of the spring 40 being for this purpose disposed in the path of movement of the lateral support 39.
  • the spring 40 here plays the role of arming spring of the automatic ejection device from the cartridge magazine, as will be shown.
  • the cylinder head stopper 28 is subjected to the pressure of the spring 20 by pushing the pusher 34 of the cartridge lifting piston 190 on its stop 33 against the return spring 35, and the stop 30 abuts against the ramp 31 .
  • the finger 250 of the cartridge lifting piston 190 is inactive, in abutment against the wall of the magazine 80, and the latter is held in place by the tooth 160 of the retainer 130 engaged in the notch 170.
  • the movable breech 60 arrives at the end of the recoil stroke, the ramp 31 disappears from above the stop 30 of the breech stop 28 and the latter , released and still subject to the pressure of the spring 20 of the cartridge lifting piston 190, pivots anticlockwise and engages said stop 30 in the notch formed by the ascent of the ramp 31, in front of the front wall 32 .
  • FIGS. 10 and 11 This possibility, illustrated by FIGS. 10 and 11, is shown applied to a weapon, the breech catch of which is constituted by a lateral stop 41, movable by translation in the transverse direction of the weapon, mounted on a slide 42 guided in two lateral slides of the walls of the carcass 43 and armed by a leaf spring 44, to engage in a notch 45 of the movable yoke 46 at the arrival of the latter in the retracted position.
  • the lateral stop 41 is secured to a contact finger 47, offset in the longitudinal direction of the cylinder head 46, passing through the side wall of the carcass 43 at the level of the cartridge magazine housing 48, and comprising an inclined contact end intended to be biased by the thrust of the inclined upper wall of the cartridge magazine 48, by wedge effect, when the latter is put in place in its housing, against the spring 44, as shown in FIG. 10 .
  • the cartridge magazine 48 still contains its last cartridge 12, while the penultimate is chambered, ready to be drawn, and this magazine is retained in its housing, as for example on the Figure 1 of the first embodiment.
  • the stop 41 of the breech retainer is released from the path of the notch 45 of the movable breech 46 by retaining its contact finger 47 bearing on the magazine 48.
  • the last cartridge 12 is chambered and the magazine for cartridges 48 is released and ejected by the automatic ejection device, as in the phase represented by FIG. 3 of the first embodiment.
  • the automatic ejection of the cartridge magazine 48 removes its support against the contact finger 47 of the cylinder head retainer and the stop 41 thereof is armed by the spring 44, ready to engage in the notch 45 of the cylinder head 46.
  • FIGS. 12 to 16 makes it possible to obtain the same effect as in the first embodiment, but here with a retainer 131 from the cartridge magazine constituted by a lateral lever integrating in its structure a drive stop 252 associated with a retainer tooth 161, these two elements being spaced one of the other.
  • the retainer 131 of the cartridge magazine 81 is for example of triangular profile having at its lower apex an axis of articulation 481, at its upper right apex, on the side of the magazine 81, a finger parallel to this axis forming the stop d drive 252 already mentioned, and at its third apex a knurled button 49 for manual control.
  • the retaining tooth 161 Between the hinge pin 481 and the drive stop 252 is located the retaining tooth 161, in a position offset towards the front of the weapon relative to a notional plane joining the hinge pin 481 to the 'axis of the drive stop 252, to facilitate its release of a retaining notch 171 from the wall of the cartridge magazine 81 during the automatic ejection action.
