Definitions
- the present invention relates to a mechanism for disassembling a gun.
- the present invention discloses a disassembly safety device.
- a first architecture consists of placing a part that can pivot around itself at the front of the barrel. This part has the function of blocking the forward movement of the barrel and the slide during the cycle of the weapon. To disassemble the weapon, simply turn this part. Its asymmetrical body then allows the barrel and slide to pass forward and disengage them from the receiver.
- This element usually takes the form of a pin or a wedge.
- An advantage of this solution is that it allows rotation of the disassembly lever only for a given position of the slide.
- a half-moon shaped cutout in the slide allows the free rotation of this lever.
- this cutout is located so as to be able to pivot the disassembly lever only when the slide has been moved back sufficiently to ensure the removal of a possible cartridge in the chamber. The disassembly sequence thus forces the user to unload the weapon.
- the user can then push the slide forward and remove the slide and the barrel out of the assembled receiver. Very often, the user must squeeze the trigger before being able to push the moving parts beyond their so-called battery position.
- this architectural principle can be coupled with an additional part set in motion when the disassembly lever is actuated. This movement (rotation or translation) is then only possible if the magazine is removed from the weapon. In other words, the lever can only be pivoted if the magazine is removed from the weapon and if the slide is in the appropriate position, then presenting its half-moon cutout opposite the disassembly lever.
- This principle of mechanism is for example described in the patent application EP2116804A1 .
- the weapon can only be dismantled by applying force simultaneously on both sides of the pallet. This prevents any risk of unintentional disassembly, which can happen with the disassembly lever. Indeed, when shooting, if the shooter presses the disassembly lever according to his grip and body shape, it happens that the lever turns when the slide arrives in the disassembly position. This prevents the next shot from being fired.
- the present invention relates to a gun comprising a disassembly protection device which comprises a disassembly key rotatably disposed in a frame and capable of being manually rotated between an angular locking position and an angular disassembly position, and said disassembly key capable of occupying a transverse position of rest and a transverse position of rotation, said disassembly key comprising blocking means cooperating with complementary blocking means on the chassis in order to prevent rotation of the disassembly key towards the angular disassembly position when said disassembly key occupies the transverse rest position.
- FIG. 1 shows an example of a gun according to the invention.
- FIG 2 shows the example of the pistol of the figure 1 , the slide in the rear position, and the disassembly key removed.
- FIG. 3 shows a cutaway view of an example of a device according to the invention (the disassembly key is here truncated and at rest, in order to show the elements under the lever of the disassembly key).
- FIG. 4 shows a bottom view of an example of a device according to the invention.
- FIG. 5 shows a perspective view of an example of a disassembly key according to the invention.
- FIG. 6 shows a partial view of the chassis of an example of a gun according to the invention.
- FIG. 7 shows a partial view of the chassis of an example of a gun according to the invention, the disassembly key in the rest position (the disassembly key is truncated in the same way as in the Figure 3 , the hatching representing the cut of the key).
- the present invention relates to a disassembly key 7, or disassembly lever which allows when it is extracted from the chassis, as shown in figure 2 , to disassemble the slide 2, the barrel 5 and the recovery spring 6 of an automatic pistol.
- a disassembly key 7 or disassembly lever which allows when it is extracted from the chassis, as shown in figure 2 , to disassemble the slide 2, the barrel 5 and the recovery spring 6 of an automatic pistol.
- it To allow the extraction of the disassembly key, it must first be turned manually by means of lever 3 from a blocking position to a disassembly position.
- chassis should be understood in the broad sense: it may be an attached part comprising the slide rails 22 and other active elements such as the control device firing. This attached part is then integrated into a carcass. It may be a metal element attached to the carcass but not including the slide rails 22 or only some of them. It can also be a single piece carcass including the slide rails.
- the blocking is carried out at the level of a metal element to avoid matting and its deformation. It can therefore be made on a metal element integrating for example the front rails or as illustrated in Figure 3 on a chassis integrating front and rear rails.
- Such blocking is advantageously obtained by a tenon 13 of the disassembly key blocking rotation in both directions by entering into a mortise 21 of the chassis.
- the rotational unlocking of the disassembly key 7 is then obtained by moving the key 7 transversely so as to cause the tenon 13 to emerge from the mortise 21.
- the disassembly key preferably comprises two indexing grooves 11,12 perpendicular to its axis, a slide 8 being able to take place in one or the other of these grooves when the disassembly key occupies the angular position in which it is blocked in rotation (angular position called locking).
- This slide 8 is kept in contact with these grooves by suitable elastic means such as a return spring 16.
- a return spring 16 When the disassembly key is pushed fully into its housing, its tenon 13 placed in the corresponding mortise 21, the slide is in the most external groove 11. This transverse position is called rest. It is this position which is illustrated in Figure 3 .
- a shoulder 17 on the disassembly key rests on the internal surface 10 of the slide and prevents the disassembly key 7 from continuing its transverse extraction movement when the key occupies an angular locking position.
- the shoulder 17 is discontinuous (ie not present over the entire circumference of the disassembly key), so that, when the key is turned towards an angular disassembly position, the shoulder 17 no longer faces the internal surface 10 slider, allowing complete extraction of the disassembly key 7.
- the dismantling key also makes it possible to prevent the weapon from being dismantled when a magazine is present in the magazine well.
- the slide 8, arranged between the disassembly key 7 and the magazine well comprises a loader feeler 15.
- the feeler 15 arranged at one end of the slide and able to penetrate into the loader well, prevents any rearward movement of the slide 8.
- This slide then supports its other end on an eccentric element 20 of the disassembly key 7.
- This eccentric element 20 is arranged on the disassembly key 7 so that, when a charger is present, the slide 8, blocked by the charger, prevents rotation of the disassembly key.
- the disassembly key comprises a tenon 14 (or comprises a half-moon or asymmetrical section) bearing under the slide and preventing the rotation of the disassembly key.
- a housing 4 under the slide 2 allows the rotation of the disassembly key only when the slide occupies a predetermined rear position. This position preferably corresponds to the rear position when the slide is blocked by a slide stop, making it simpler to maintain this position. This position is illustrated in figure 2 .
- the presence of this tenon 14 therefore makes it possible to ensure that no ammunition is chambered, the backward movement ensuring the ejection of any ammunition.
- the external face of the slide 8 comprises an inclined external sliding surface 9, making it possible to push the slide 8 backwards when inserting the disassembly key into its housing. It is interesting to note that, in this case, the disassembly key can be replaced even if the slide is in position, in the breech closed position. In fact, it is then not necessary to turn the disassembly key.
