Definitions
- the present invention relates to a safety mechanism integrated into a firing mechanism of a machine gun.
- 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.
- firing with a band of ammunition is preferred because it allows to draw a large amount of ammunition without having to interrupt to change charger.
- firing control generally includes only an automatic function. That is, the weapon fires only in a burst. It does not shoot in semi-automatic mode, that is to say shoot only one shot each once 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.
- a trigger tail a stopper stopping the moving parts in the open position, the rear of the carcass
- a trigger holding the stopper in the down position during the movement towards the 'before moving parts.
- To release the movement of the moving parts (breech and breech support), it is necessary to press the trigger which pushes on the stop to erase it from the stroke of moving parts.
- the front end of the stopper is intercepted by the trigger which is not in the path of moving parts as the operator presses the trigger.
- 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 a certain limitation of the wear of the trigger of the stop because it ensures a stop moving parts in the rearmost possible position.
- 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.
- 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 recoil that would not catch the anti-runaway screen could not load a new cartridge, preventing further shooting.
- the security is achieved by a transverse pusher system 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 that releases the parts mobile.
- 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 starting mechanisms for weapons operating with an open bolt do not all have the trigger system.
- the trigger tail directly controls the stop. This means that it is possible for the operator to release the stop while the moving parts are moving forward.
- the stop will not necessarily hook the moving parts with an optimal contact (face against face), that with a speed of moving parts potentially important (if the catch not stopped by the stop is not the notch corresponding to the moving parts in the rear position but the anti runaway screen), which implies that the wear of the stop trigger is increased compared to that of a mechanism having a trigger. Too much damage to the trigger can compromise the safety and reliability of the weapon.
- 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.
- patent EP 2205925 B1 describes a particular mechanism in which the retainer consists of two parts: a lever stopper 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 moving parts are pulled backwards while the safety 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.
- EP 2205925 B1 A disadvantage of the system proposed in 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 motion to the tail of relaxation, that even in position of safety.
- patent EP 2831531 B1 describes a mechanism modified to allow the user to engage security regardless of the position of the stop. In this new mechanism, the trigger tail and the trigger have been disengaged by the introduction of an intermediate piece. In fact, 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 shot 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.
- EP 2831531 Bl is the lack of a semi-automatic firing function.
- the lack of semi-automatic firing capability is detrimental to the flexibility of a versatile machine gun.
- the need for versatility of the weapon is related to deployment issues and in particular to the level at which the weapon is to be distributed.
- weapons not firing ammunition tape but operating with an open bolt had both semi-automatic and automatic function. 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 which do not allow the user of an automatic rifle (or a submachine gun) to maintain its firepower for a period long enough to provide as much support as the a machine gun.
- the semi-automatic operation of these weapons with open breech is often obtained via a disconnector between the trigger 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 tail is sufficient for the disconnector to come into abutment before the trigger tail and release the stopper which intercepts the moving parts after the first shot fired . If this solution was accepted a time for some weapons, it has the disadvantage of being theoretically fallible if the operator strongly supports the trigger tail to release the slide but not enough so that the race is completely completed. At this point the gun was fired while the operator was expecting a single shot which is a major security problem.
- the firing selector of the UZI submachine gun does not act on the race of the trigger tail but directly on the disconnector.
- a stop is present on the movement of the disconnector which releases the stopper.
- the designers of the submachine gun BREN have opted for a mechanism having a rather particular 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 the 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 When the fire selector is in the semi-automatic firing position, the disconnector is in the up position so that the protrusion is in the path of the moving parts.
- the operator presses the trigger the effort and transmitted to the stop that releases the moving parts.
- the moving parts As the moving parts move forward, they press on the disconnector that releases the lift from the stop. This happens as soon as the moving parts are released so that the stopper is again in position to stop the moving parts after the first shot.
- the lever arm of the disconnector on the stop is low. This results in a decrease in the stroke of the trigger tail with maximum effort to trigger the shot.
- the present invention relates to a safety device of a firearm for preventing the triggering of a shot, without blocking the reset function, and can preferably be engaged regardless of the state of the weapon, said weapon comprising a movable stop between a stopping position blocking the moving parts of the weapon in the rear position and a release position allowing the movement in both directions of said moving parts said security device comprising an element of movable security between a stop position of the stop in the stop position and a release position of the stop, said security element resting on a stationary part of the weapon and said element of safety can be moved to the release position of the stop by a movement towards the rear of the moving parts.
- the term moving parts all the parts set in motion by the cycle of reloading the weapon.
- This is for example an assembly comprising a slide in which a lock moves, the slide can be secured to a gas recovery piston. It may also be more simply a cylinder head in the case of an unsecured cylinder head.
- the security device of the invention comprises an appropriate combination of at least one of the following features:
- the raising of the stop is controlled by a trigger pivoting about an axis disposed on a front portion of the stopper and being held by a hook to a trigger tail or a rocker connectable or disconnectable from the trigger tail during the releasing the trigger or disconnecting the rocker until the passage of the moving parts towards the rear of the weapon;
- the security element is placed in the path of the stopper by an elastic return element
- the advance of the release of the return movement of the safety element under the stop on the raising of the stop is obtained by an opposition between the direction of movement of the safety element towards the release position of the stop and the recoil of moving parts;
- the movement of the safety element towards the position of release of the stop by the retracting movement of the moving parts is obtained by an intermediate lever or an intermediate wheel;
- the security element pivots about a fixed axis in the weapon
- the security element is erased by the moving parts by the cooperation between the sliding surfaces of the moving parts and the sliding surface of the security element;
- the security element slides in a direction orthogonal to the movement of the stop.
- a second aspect of the invention relates to a starting mechanism incorporating the safety device of a firearm according to the first aspect of the invention.
- the starting mechanism of the invention comprises a semi-automatic firing function which is obtained by a mechanism further comprising a rocker actuating the retainer, and a trigger tail linked to the rocker by a disconnector which can either provide a mechanical coupling between the trigger tail and the rocker, or disconnect said mechanical coupling between the trigger tail and the rocker, said disconnector being arranged to switch the rocker from the firing position to the rest position to prevent the start of the next stroke when the trigger tail is held in the firing position.
- the selection function of the automatic firing function, semiautomatic and the function of selection of the safety function are performed by the same command for the operator.
- control mechanism consists of a rotary lever actuating a slide that can move in translation and allowing activation or deactivation of the functions related to semi-automatic shooting 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 moves a safety control pin attached to the security element whose shape allows the permanent positioning of the security element in the release position of the security element.
- a safety control pin attached to the security element whose shape allows the permanent positioning of the security element in the release position of the security element.
- the shape of the slider blocks the trigger when the security is engaged and releases it when the firing selector is in the semi-automatic or automatic position.
- the various slider lights comprise notches in which the different lugs are housed when the selector is at a selection position, so as to prevent the selector can find a stable equilibrium position between two positions, making the state of the weapon ill-defined.
- the invention also relates to a gun operating open yoke and comprising a starting mechanism incorporating the safety device of a firearm according to the first aspect of the invention.
- Figure 1 shows an exploded view of an example of a starting device according to the invention.
- Figures 2a to 2d show different sections of an exemplary mechanism of the invention with the various parts assembled, the moving parts being arranged in the rear position and the security being engaged.
- Figure 2e shows a perspective view of the example of the mechanism of Figures 2a to 2d (in the safety position).
- Figure 3 shows a section of a device according to the invention, selector in the semi-automatic position.
- Figure 4 shows a section of the device of Figure 3 where the slide is no longer visible, pressed trigger tail, moving parts moving forward.
- Figure 5 shows the same section as Figure 4, after stalling the disconnector.
- Figure 6 shows a section of the device of Figure 2, the slide being visible, the selector at the automatic position and the weapon at rest.
- Figures 7 and 7a show a section of the device of Figure 6, to better observe the interaction between the different parts.
- Figure 8 shows an alternative mechanism of disconnection between the trigger and the rocker, trigger bar partially engaged.
- FIG. 9 shows the disconnection mechanism of FIG. 8, end-of-travel trigger tail.
- Figure 10 shows the mechanism of Figure 8, in automatic mode.
- Figure 11 shows an alternative of automatic operation.
- the fire selector must be able to enter the safety position regardless of the condition of the weapon.
- 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 firing selector is connected to the security element so as to allow it an amplitude of movement when the firing selector is in the safety position but forcing the erasure of the security element of the firing stroke. the stop when the fire selector is in a firing position (semi-automatic or automatic).
- the trigger is not mounted in rotation on the trigger but mounted directly on the stopper or on a moving rocker positioned between the trigger tail and the trigger.
- the connection between the trigger and the trigger tail is performed via a hook shape allowing the trigger tail to return to its rest position that even if the trigger continues to hold the stopper in a low position.
- This feature makes it possible to solve the problem of the 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 EP 2831531 B1 (solution plus expensive).
- 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 race the stopper so as to prevent the movement of moving parts, but can be erased by the moving parts when the moving parts are moving 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 release in 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 of the moving parts has completely passed the trigger of the stop.
- the security element resumes its function as soon as the stopper rises after crossing each notch of moving parts so that there is no risk that an intermediate position where the parts mobile devices could be based on the stop without security being involved.
- the reversal between the direction of erasure of the security element and the authorized movement of the moving parts can be obtained via an oblique contact between the two sets (cam shapes) or through an intermediate lever. to both sets.
- the starting mechanism has been modified according to the following principle:
- the trigger tail is divided into two elements. One of these elements still ensures the function of the trigger tail relative to the user. This element is hereinafter referred to as the trigger tail.
- the other piece performs the internal functions of the weapon namely to push the stopper to release the movement of moving parts and act on the trigger to allow the stopping of moving parts. This piece is named after the rocker.
- a disconnection function is added between the trigger tail and the rocker such that when the firing selector is placed on the semi-automatic firing position, the advance movement of the moving parts causes a detachment between the trigger tail. and the rocker allowing the latter to switch to the firing stop position while the operator is still pressing the trigger tail.
- 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-position. automatic.
- 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 can be performed in one piece if the stroke of the trigger is different between the automatic firing mode. and the semi-automatic firing mode.
- 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.
- disconnector For this reason it is preferable to use for disconnection to a two-piece mechanism (namely the disconnector and a trigger disconnector).
- 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 When 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 fire selector for setting the security of the weapon is the same as that for selecting between a semi-automatic operation and automatic operation, it is preferable that the choice between these different functions passes through the same control in the form of a three position rotary lever.
- the junction between the lever and the different elements performing the functions Security and semi-automatic 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 security element and the trigger disconnector) via lights whose shape allows either block 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 is the firing selector and the selector slider is a geared gears type rack.
- Other alternatives are nevertheless possible (eccentric on the selector passing in a vertical oblong hole in the selector slider or crank connecting system ).
- the axis of the selector of shot also realizes the function of axis of rotation for the stop.
- Figure 1 shows an exploded view of an example of a starting device according to the invention.
- This device comprises a retainer 5 for stopping the moving parts 2 in the rear position by bearing on notches formed in the bottom of the moving parts 2.
- This retainer 5 comprises in its front part an axis 16 supporting a trigger 10.
- This trigger includes at its base a hook 15.
- the stop and trigger assembly are attached to the devices via an axis 29.
- This trigger 10 can maintain 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 flip-flop 12 is disposed between the detent 13 and the stop 5. This flip-flop
- the semi-automatic firing function is essentially implemented by the presence of a disconnector 11 and a disconnector trigger 14, to separate the trigger tail 13 from the flip-flop 5.
- the safety function is essentially implemented by the addition of a security element 1 and the presence of a locking pin 34 of the trigger tail 13.
- the selection of the different modes of operation of the weapon to know security, shot by shot, or automatic firing is performed by means of a slider 20 actuated by a gear 26 disposed on an axis 29 and actuated by the Shooting selector 24. How security works
- Figures 2a to d show different sections of a mechanism of the invention with the various parts assembled, the moving parts being arranged in the rear position and the safety being engaged.
- the moving parts 2 are locked in the rear position by the stopper 5, the stopper 5 being further maintained in the upper position by the safety element 1 blocking the stopper 9 of the stopper in position high.
- This security element 1 is held in this position by a spring 6. It is seen in this situation the fact of pressing the trigger 13 does not move the stop and release the moving parts.
- the safety control light 21 of the slider 20 allows the rotation, and therefore the erasure of the security element when the moving parts are moved backwards. This erasure is induced by the sliding of the sliding surface 3 on the corresponding surfaces 4 under the moving parts.
- the movement of the rocker 12 is limited by the lug 19 in the slot 22 and the movement of the trigger pin 13 is limited by the locking pin 34 of the trigger rod 13 taking support under the slide 20.
- Figure 3 shows a section of a device according to the invention, selector in the semi-automatic position.
- the slider 20 pushes the safety element 1 out of the path of the stop 9 by means of the security control pin 8 sliding in the safety control light 21, the control light 22 of the lever releases the movement of the rocker control pin 19 and the trigger lock pin 34 may move in the release clearance of the trigger tail.
- the light of Disconnector Trigger Switch 23 Lifts the Disconnect Trigger in the Path of Moving Parts 2.
- FIG. 4 represents a section of the device of FIG. 3 in which the slide is no longer visible, so as to see the movement of the rocker 12, the trigger rod 13, the disconnector 11 and the trigger of FIG. disconnector 14 in semi-automatic operation.
- This figure shows the state of the cycle where the trigger is pressed, the moving parts advance forward, and the disconnector trigger 14 has not yet decoupled the rocker 12 of the trigger rod 13.
- the trigger tail 13 When the trigger tail 13 is pressed, it rotates about the axis 17, driving the latch 12 which pushes via the rocker control pin 19 on the retainer 5, causing the release of the moving parts 2.
- the coupling between the trigger pin 13 and the rocker 12 is provided by the disconnector 11 rotating about an axis fixed to the rocker 12 and clinging to a pin 30 on the trigger rod 13.
- a lever 35 of the disconnector trigger 14 is placed between the latch 12 and the disconnector 11, so that when the movable parts 2 press on the cam 36 of the disconnector trigger 14, said lever 35 picks up the disconnector 11 of the lug 30 of the trigger rod 13. This stall has the effect of returning the rocker 12 to its rest position, placing the trigger 10 in the passage of moving parts 2.
- FIG. 5 shows the various parts after disconnection of the flip-flop 12 of the trigger pin 13 by the trigger of the disconnector 14.
- FIG. 8 shows a semi-automatic firing selector alternative in which the disconnection is provided by a stop 40 disposed in the path of the disconnector 11.
- the disconnector 11 comes into contact with the stop 40 just after the release of the moving parts 2 by the stopper stop 9. This contact rotates the disconnector 11 about its axis 18, which decouples the disconnector 11 of the tail of relaxation 13.
- FIG. 9 shows the device of FIG. 8 just after disconnection of the flip-flop 12, following the extension of the stroke of the trigger rod 13.
- the stop 40 has been erased from the trajectory of the disconnector for automatic firing.
- Such a position of the abutment 40 may advantageously be obtained by a particular geometry of a light of a firing control slider, moving the lug 41 of disconnection stop control.
- the disconnector In all cases, in semi-automatic mode, the disconnector returns to its coupling position between the trigger 13 and the flip-flop 12 when the trigger tail is released by the operator.
- Figure 6 shows a section of the device of Figure 2, the slider being visible, and the selector at the automatic position. In this position, it can be seen that the disconnector trigger control light 23 displaces, by the pin 32, the disconnector trigger 14 out of the path of moving parts 2, thus preventing disconnection between the trigger pin 13 and the rocker 12, allowing automatic firing.
- Figures 7 and 7a show two sections of the device of Figure 6, to better observe the interaction between the different parts.
- the trigger is at rest, while in Figure 7a, the trigger is pressed.
- the disconnector trigger lever 14 comes behind the disconnector lever 11 and maintains the disconnector in the coupled position. This characteristic can be useful in the context of firing burst, causing very strong vibrations that can cause inadvertent decoupling between the rocker 12 and the trigger 13.
- Figure 11 shows an alternative automatic operation, wherein a second lug 50 disconnector is disposed on the latch.
- This additional lug 50 is arranged so that, when the disconnector 11 is supported, it is no longer in the race of the disconnect lever of the disconnector trigger 35.
- the disconnector trigger can not further disconnect the coupling between the trigger 13 and the latch 12.
- this alternative is also transposable exactly the same way to the alternative in which the disconnection is provided by a stop 40 disposed in the path of the disconnector 11. Note that in the latter case, the stop 40 may be a fixed element, since it must not be moved for the automatic mode.
- disconnector axis could easily be placed on the trigger, and or the disconnector pins on the rocker.
