Definitions

  • the present invention relates to a starting mechanism of a firearm, in particular an automatic or semi-automatic firearm operating with an open breech.
  • a machine gun is traditionally a weapon used for suppression fire.
  • the goal of suppression fire is to water the combat zone with a large amount of projectiles. We then speak of the quality of "firepower" of the weapon used.
  • the firing with a band of ammunition is privileged because it makes it possible to draw a large quantity of ammunition without having to stop to change charger.
  • firing control usually includes only an automatic function. That is, the weapon fires only in a burst. It does not fire in semi-automatic mode, that is to say pull only one shot each time the trigger is pressed. Closed-breech shotguns often have dual functionality: semi-automatic shooting and automatic shooting.
  • the starting mechanism consists of a trigger tail, a stopper stopping the moving parts in the open position, the rear of the carcass, and a trigger holding the stopper in the down position during the movement towards the 'before moving parts.
  • the trigger When the operator releases the trigger tail, the trigger returns to the path of the moving parts by holding the stopper in the firing position until the moving parts retreat. When the moving parts move backwards, they push the trigger backwards, which releases the stop. The moving parts are then again blocked by the stop in the rear position under the pressure of the recovery spring of the weapon.
  • the trigger mechanism allows some limitation of the trigger sear wear as it ensures that the moving parts are stopped in the most rearward position possible. When the moving parts are at the rear, their speed is low, which implies that the kinetic energy of the moving parts, which will be communicated to the stop when stopped, will be at its minimum. In addition, this mechanism avoids the risk that the moving parts are held by the anti-runaway notch while the machine gun does not suffer a lack of recoil.
  • the anti-runaway screen is a locking screen below the moving parts to block them when they do not back away enough to hook the normal screen.
  • a lack of recoil can prevent the hanging of the moving parts at the stop when the trigger is released, inducing a gust of fire while the operator seeks to stop the shot.
  • the anti-runaway screen is arranged to lock the moving parts in their forward motions just after hanging the back of the standby cartridge. In this way, a lack of hindsight that would not hang over the anti-runaway screen could not charge a new cartridge, preventing further shooting.
  • the security is achieved by a pusher system transverse to the axis of the barrel of the weapon.
  • the pusher In the position allowing the automatic firing the pusher allows the lowering of the stop which releases the moving parts.
  • the stopper abuts the pusher before the moving parts can disengage from the trigger. This particularly simple and effective mechanism does not allow the rearming of the weapon when security is engaged or semi-automatic firing.
  • the security consists of a movable axis transverse to the weapon and limiting the movement of the stopper when the weapon is in "safe" position. This implies that the weapon can not be reset if the safety is engaged because the stop can not fade from the path of moving parts when they recede. Another consequence is that safety can not be engaged if the moving parts are ahead because the trigger keeps the stop cleared until the moving parts have been moved back manually.
  • the patent EP 2205925 B1 describes a particular mechanism in which the retainer consists of two parts: a stop lever and a safety lever.
  • a spring between the stop lever and the safety lever forces the latter into a rest position so that it does not perform its stop function against the firing selector when the parts mobiles are pulled backwards while security is engaged.
  • the moving parts return forward under the strain of the recovery spring, the moving parts tilt the safety lever and stop at the stop lever. By tilting, the safety lever is placed in a position that allows it to perform a function of limiting the stroke of the stop when the safety is engaged.
  • a disadvantage of the system proposed in the patent EP 2205925 B1 is that to allow the user to engage security regardless of the condition of the weapon, it is necessary to allow a certain range of movement to the trigger tail, even in the safety position.
  • the patent EP 2831531 B1 describes a modified mechanism to allow the user to engage safety regardless of the position of the stop.
  • the trigger tail and the trigger have been disengaged by the introduction of an intermediate piece.
  • the stroke of the trigger tail can be canceled by the fire selector when the latter is in the safety position while the stopper is held in the low position by the trigger.
  • EP 2205925 B1 and EP 2831531 B1 Another disadvantage of the system presented by EP 2205925 B1 and EP 2831531 B1 is the fact that the safety lever is directly supported on the axis of safety (pivoting lever serving as a two-position fire selector: safe and automatic).
  • This architecture has the disadvantage of putting the efforts related to the limitation of the movement of the stopper on an intermediate part with respect to the sub-guard.
  • the contact that limits the movements of the stop is made on a cam-shaped part. This form of cam is necessary to allow the movement of the stopper when the selector lever is in the automatic firing position, but also to allow the descent of the stop when the moving parts are brought back while security is engaged. .
  • non-ammunition-fired weapons with open bolts had both semi-automatic and automatic functions. These include the Bren submachine gun and the Uzi submachine gun. These weapons are hybrids between support weapons and individual weapons that allow their operators to fulfill the support role for a limited time to support other operators using weapons with more limited firepower (a rifle or gun).
  • the charger power supply has intrinsic limitations that do not allow the user of an automatic rifle (or a submachine gun) to maintain its firepower long enough to provide as much support as a machine gun.
  • the semi-automatic operation of these open bolt weapons is often achieved via a disconnector between the trigger tail and the stopper.
  • the stroke of the trigger tail is more limited when the fire selector is in the automatic firing position so that the trigger tail keeps the stopper in the down position (cleared from the detents on moving parts).
  • the stroke of the trigger is sufficient for the disconnector to come into abutment before the trigger and release the stopper that intercepts the moving parts after the first shot. . If this solution has been accepted a time for some weapons, it has the disadvantage of being theoretically fallible if the operator is pressing hard enough on the trigger to release the slide but not enough for the race to be completely completed. At this point the gun was fired while the operator was expecting a single shot which is a major security problem.
  • the UZI submachine gun's firing selector does not act on the tail stroke. relaxing but directly on the disconnector.
  • a stop is present on the movement of the disconnector which releases the stopper.
  • the designers of the BREN submachinegun have opted for a mechanism with a rather special disconnector.
  • the latter has two possibilities of contact to cause the lowering of the stop and a protrusion that can come in the path of moving parts.
  • the disconnector joins the detent to the stopper from the bottom of the latter so that the protrusion of the disconnector is not in the path of the moving parts.
  • the stroke of the trigger tail is rather long with a fairly low effort (the lever lever of the disconnector on the stop being at its maximum).
  • the disconnector is in the up position so that the protrusion is in the path of the moving parts.
  • the present invention relates to an expansion device for an open bolt-action firearm comprising a stopper for stopping the forward movement of moving parts, a trigger for raising the stopper during the backward movement of moving parts, a rocker actuating the stop and the trigger when starting and stopping shots and a trigger tail linked to the rocker by a disconnector that can switch from a mechanical coupling position between the trigger and the trigger toggles, at a mechanical decoupling position between the trigger and the rocker, the rocking lever from a firing position to a rest position when the disconnector switches from its coupling position to its decoupling position, so as to prevent the start of the next stroke when the trigger tail is held in the firing position.
  • the disconnection between the trigger rod and the rocker is obtained by a stop in the device positioned in the path of the disconnector.
  • the disconnector is arranged so that the moving movement of the moving parts disconnects the mechanical connection between the rocker and the trigger tail.
  • the moving parts comprise a cam on their lower surface arranged to disconnect the mechanical coupling between the rocker and the trigger tail during the movement of the moving parts forward.
  • the expansion device of the invention comprises a disconnector trigger that can occupy a rest position or a disconnection position, said disconnector trigger comprising a disconnection lever arranged, when in the disconnected position, between the rocker and the disconnector and a disconnect cam controlled by the movement of the moving parts, the disconnector disconnecting the mechanical connection between the rocker and the detent when a cam under the moving parts displace the cam disconnection.
  • the preferred alternative of the invention comprises a firing selector for selecting between a semi-automatic firing function and an automatic firing function.
  • the semi-automatic or automatic firing mode is selected by modifying the fulcrum of the disconnector on the trigger or flip-flop so that the disconnector can not disconnect the trigger tail from the flip-flop when the Auto fire mode is selected.
  • the selection of the semi-automatic or automatic firing mode is achieved by moving the disconnector trigger out of the path of the moving parts and the disconnector path so that the disconnector can not disconnect the trigger tail from the disconnect path. Toggles when the auto fire mode is selected.
  • a security function authorizing the loading function when security is engaged said security function being performed by a security element comprising a blocking surface for blocking the stopper in the stopping position of the moving parts, said security element supported on a fixed part of the weapon and can be erased by the moving parts when it moves from a forward position to a rear position.
  • the selection function of the semi-automatic firing function and the selection function of the safety function are preferably performed by the same command.
  • control mechanism consists of a rotary lever actuating a slider operating in translation and allowing activation or deactivation of the functions related to semi-automatic firing, automatic firing and security so that three positions the lever correspond to a safety position, a semi-automatic firing position and an automatic firing position.
  • the slide comprises a safety control light in which a safety control pin disposed on the security element moves, the shape of said safety control light being determined so that, when the lever of selector is in the safety position, the safety element can move between a locking position of the stop and a non-locking position of the stop, and when the lever is in another position, the element of safety is in the non-locking position of the stop.
  • the slider includes a disconnector trigger control light in which a disconnector trigger control pin disposed on the disconnector trigger is moved, the shape of said trigger control light. disconnector being determined so that when the selector lever is in the semi-automatic position, the disconnector trigger can move between its disconnected position and its rest position, and when the lever is in an automatic position , the disconnector trigger is locked in the rest position, out of the path of the moving parts.
  • the various slider lights comprise notches in which the different lugs are housed when the selector is at a selection position, so as to avoid that the selector can find a position of stable equilibrium between two positions, making the poorly defined weapon status.
  • the stroke of the stop is limited by a security element bearing on a stationary part of the weapon.
  • This security element can be cleared from the stroke of the stopper to allow the passage of moving parts from the front to the rear of the weapon. Cams under the moving parts allow this erasure.
  • a return spring returns the safety element into the path of the stopper each time a detent of moving parts exceeds the trigger of the stop.
  • the fire selector is connected to the security element so as to allow it to be moved when the fire selector is in the safety position but forcing the erasure of the safety element of the stroke of the stop when the fire selector is in a firing position (semi-automatic or automatic).
  • the trigger is not mounted in rotation on the tail of trigger but mounted directly on the stop or on a moving rocker positioned between the trigger tail and the trigger.
  • the connection between the trigger and the trigger is performed via a hook shape allowing the trigger tail to return to its rest position even if the trigger continues to keep the stopper in a low position.
  • This peculiarity makes it possible to solve the problem of engagement of the safety of the weapon whatever its condition by dispensing with the two-piece separation of the trigger tail which is the solution proposed in the patent.
  • EP 2831531 B1 (more expensive solution).
  • an intermediate flip-flop may be useful for semi-automatic use.
  • the trigger hook does not rest directly on the trigger, but on the intermediate rocker. Note that in this case, the rocker is only useful for semi-automatic firing: when the safety reset is initiated, the flip-flop is not necessarily disconnected from the trigger tail.
  • the essential element is the presence of a security element resting on a rigid part of the weapon, limiting the stroke of the rifle. stopper to prevent movement of moving parts, but which can be cleared by moving parts when moving parts from front to rear.
  • the trigger is mounted on the stop and not on the trigger, allowing integration into the firing selector of a stop to limit the stroke of the trigger while allowing the safety of the weapon whatever the condition of the weapon.
  • Limiting the stroke of the trigger is a simple and effective indicator to indicate to the operator that the fire selector is in the safety position.
  • the direction of erasure of the security element is forward, so that the action of the moving parts during their rearward movement on the security element is interrupted before the notch stopping the moving parts has completely exceeded the trigger of the stop.
  • the security element resumes its function as soon as the stop goes up after crossing each notch moving parts so that there is no risk that an intermediate position where the moving parts could rest on the stop without security is engaged.
  • the reversal between the erasure direction of the safety element and the allowed movement of the moving parts can be obtained via an oblique contact between the two sets (of the cam shapes) or through an intermediate lever to the two sets .
  • the disconnection can be obtained by a stop disposed in the path of the disconnector.
  • this stop is placed in the path of the disconnector only when the firing selector is in semi-automatic position.
  • the stop is fixed, but the stroke of the trigger tail is limited automatically so as to prevent contact between the stop and the disconnector.
  • the disconnection function between the rocker and the trigger tail can be performed in one piece if the stroke of the trigger tail is different between the automatic firing mode and the mode.
  • semi-automatic shooting In this case the moving parts act directly on the disconnector when the firing selector is in the semi-automatic position. This method is simple to implement but has the disadvantage of modifying the control effort requested by the operator according to whether he pulls semi-automatic or automatic.
  • the disconnector always acts between the trigger and the flip-flop, but the disconnection control is communicated by the moving parts to the disconnector via the disconnector trigger.
  • the firing selector no longer acts on the stroke of the trigger but on the positioning of the disconnector trigger before firing.
  • the firing selector is in the semi-automatic firing position, the firing trigger is in a rest position in the path of the moving parts, whereas when the firing selector is in the firing position, the firing trigger is disconnector is placed in a position out of the path of the moving parts.
  • the firing selector allowing the security of the weapon is the same as that allowing the selection between a semi-automatic operation and an automatic operation, it is preferable that the choice between these different functions goes through the same command in the form of a rotary lever with three positions.
  • the junction between the lever and the various elements performing the security and semi-automatic functions can be direct. In this case, it can be complicated to simultaneously control many potentially distant parts of each other.
  • Another aspect of the invention therefore relates to a selector slide transforming the position of the lever into a possible positioning of the parts (in particular the element of safety and trigger disconnector) via lights whose shape allows to block (or limit movement) lugs on the parts to be controlled, or to leave a degree of freedom to said lug (for example for safety).
  • This slider is particularly interesting in the example described below, but, it is more generally advantageous whenever the various elements to control are numerous and distant from each other.
  • the link may be the fire selector and the selector slider to be a geared rack-and-pinion type link.
  • Other alternatives are nevertheless possible (eccentric on the selector passing in a vertical oblong hole in the selector slider or crank connecting system ).

  • the stop and trigger assembly are attached to the devices via an axis 29.
  • This trigger 10 keeps the stopper 5 out of the path of the moving parts 2 during their forward movement, even when the trigger tail 13 is released. The positioning of the trigger 10 at the end of the stop allows the security and reloading of the weapon regardless of the state of the weapon.
  • a rocker 12 is disposed between the trigger 13 and the stop 5. This latch 12 disconnects the trigger 13 of the stop 5 which, as we will see later, will allow the selection of a shot semi-automatic.
  • the semi-automatic firing function is essentially implemented by the presence of a disconnector 11 and a disconnector trigger 14, making it possible to separate the trigger tail 13 from the flip-flop 5.
  • the safety function is essentially implemented by the addition of a safety element 1 and by the presence of a locking pin 34 of the trigger tail 13.
