Description

FIREARMS PROVIDED WITH A QUICK SAFETY DEVICE AND KIT SAFETY DEVICE

Objects of the invention

The present invention relates to a semi-automatic type single action firearm such as a pistol, provided with a rapid safety device. The present invention also relates to the safety device to be mounted on the firearm, which is presented in the form of a "kit".

The present invention also relates to a right / left-handed charger stopper.

Technological background and state of the art

Firearm safety devices are already known to prevent the involuntary percussion of the gun dog. These safety devices are of two types.

For single action type firearms, the dog can be locked in the rear position, which nevertheless exposes him in the event of a fall. This system therefore has the disadvantage of causing damage to the mechanisms at the level of the dog and the trigger or the untimely departure of a bullet during a fall of the weapon.

Another safety device for handgun Single action type fire is described in document US-A-5208406, in which only the upper part of the dog is manually pivoted forward in a safety position which prevents it from striking the striker. This is done by putting pressure on the dog. However, the dog is not blocked or locked in this position which leaves a risk, for example during a fall.

The firearm can also be of the double action type. In this case, the safety position of the dog is the front position. The first part of the trigger stroke drives the dog backwards and the second part of the stroke allows the dog to be pulled freeing the dog forward towards the striker. In this case, the run is longer, and therefore, the shooting time is all the more important. We also observe that the force to be applied on the trigger is particularly important. On the other hand, there remains a doubt for the user on the position of the dog when he pulls the trigger. A firearm of this type is described in document EP-A1-0550238.

We have also proposed, in order to reduce the force to be applied to the trigger to arm the dog, in document US-A-4312263, a firearm in which the trigger is blocked by pushing the dog towards the 'before. In this position, a safety ring also makes it possible to lock the slide. To unlock the safety of the firearm, you must first arm the dog by acting on the trigger (first action) and then continue to press it to trigger the fire (second action).

Similarly, documents US-A-5166458 and EP-A2 -0801285 describe devices for protection which reduce the effort to be applied to the trigger to arm the firearm. In this case, the dog contains a spring plunger which engages, without locking, on the cams of the dog ring.

Aims of the invention

The object of the present invention is to provide a rapid safety device in the form of a kit to be mounted on a semi-automatic type firearm such as a pistol, as well as the firearm itself comprising said safety device. , which would not have the drawbacks of the state of the art.

The present invention aims more particularly to propose a safety device intended essentially for use on single action weapons, thus making it possible to obtain a precise shot which does not require a change of position of the trigger between the first shot and the subsequent shots while maintaining the protective qualities of double action weapons. An additional aim of the present invention is to provide such a safety device which, mounted on the firearm, also makes it possible to reduce the risk of damage to the dog and / or the trigger in the event of a fall. Another object of the present invention is to propose a device which, by a single movement, makes it possible to lock the firing of the weapon, and which likewise, by a single movement, makes it possible to release the locking, this without pressing trigger, to have the firearm in a ready-to-fire configuration.

Another object of the present invention is to provide a security device in the form of a kit, which relatively easily adapts to a particular type of weapon while keeping the initial structure of a firearm already in service, without having to resort to additional machining of the weapon concerned or of the parts constituting it for the mounting the kit.

Main characteristic features of the invention

A first object of the present invention relates to a semi-automatic type single action firearm having a firing system by interposed dog such as a pistol or possibly a revolver which, through '' a trigger actuated by the trigger, distributes the cartridge either in a slide in the case of a pistol, or in a barrel in the case of a revolver having means for blocking the hammer when the latter is disposed in the front position thus causing the firearm to be locked.

These blocking means comprise at least one cocking lever which undergoes an automatic latching when the dog is placed in the front position.

Preferably, this latching of the cocking lever also makes it possible to lock the slide, which can no longer move back, and possibly to block the trigger and / or the trigger.

In a particularly advantageous manner, the blocking means also serve to suppress the safety of the firearm by causing the dog to return to the armed position and by unlocking if necessary the slide, the trigger and / or the trigger.

Another object of the present invention also relates to a semi-firearm automatic single action with a firing system by interposed dog such as a pistol or possibly a revolver which, via a trigger actuated by the trigger, distributes the cartridge either in a slide in the case of a pistol, either in a barrel in the case of a revolver having means other than the trigger for unlocking or unlocking the dog disposed in the front position, the slide, the trigger and / or the trigger. A third object of the present invention relates to a safety device presented in the form of a kit intended for a semi-automatic type firearm having a firing system by interposed dog such as a pistol or possibly a revolver, which could be originally mounted on the firearm or which fits on the firearm already in service, characterized in that it comprises a dog striking the striker of the weapon during firing, a dog ring cooperating with the dog, a trigger actuated by the trigger of the weapon and which, when fired, makes it possible to release the dog ring, a dog tail comprising the spring of the dog which is compressed to arm the dog and which, when fired, pushes the dog ring to strike the dog against the striker, an arming lever possibly left and / or right which is actuated manually to release the active safety devices by unlocking the trigger, the dog and sliding ière, a return spring to return the dog back to the armed position ready to fire in single action and possibly a fast shooting lever which cooperates with the cocking lever, the dog and the dog ring.

Preferably, the safety device also comprises a cocking lever spring which is preferably fixes on the cocking lever either right or left, a dog spring which hooks by means of a pin to the tail of the dog as well as a pin fixed on the cocking lever and a spring trigger. A final object of the present invention relates to a right / left-handed magazine stopper intended for a semi-automatic type firearm having a magazine stopper with horizontal displacement moving on either side of the weapon comprising a button located at the central level of the left grip to release the magazine by pushing said button preferably from the left to the right and a small lever located at the center of the right grip to release the charger by pushing said lever preferably top to bottom.

Description of several preferred embodiments of the invention

The rapid safety device presented in the form of a kit and referred to below as "safety fast shooting", can be fitted as standard to a semi-automatic type firearm such as a pistol or be capable of being adapted to from a kit on a weapon already in service. In the latter case, the modification will be very simply carried out by any gunsmith using the said kit corresponding to the intended firearm, the rest of the weapon remaining identical to the original firearm. The particularly simple safety device adapts to any semi-automatic type firearm without modifying the firing characteristics of said weapon.

Several preferred embodiments of the present invention are described below for three particular semi-automatic weapons, which are the GP, the Coït 45 and the SIG P220 series.

FIG. 1 represents an exploded view of the various parts forming the kit to be mounted and constituting the rapid safety device intended to be placed on a GP pistol. This kit includes, in the GP embodiment, a hammer 11, a return spring 13, a trigger 14, a so-called "fast shooting" lever 16, a left cocking lever 17, possibly a cocking lever right 18, a dog's tail 21 and a dog's ring 12, all of these parts, except the trigger 14 and the so-called "fast shooting" lever 16, being on the same axis in the case of a GP type weapon . To these parts are added the spring of the cocking lever 20 which is preferably fixed on the right cocking lever 18 or left 17, the dog spring 22 which is hooked by means of a pin 23 of the tail of the dog on the tail of the dog 21, a pin 19 being fixed on the right cocking lever 18 and a spring 15 in the trigger which rests on the trigger 14.

Figures 2 describe the different positions of the different parts of a pistol according to the different arming, firing or security phases.

Figures 3 show in section the different parts constituting the safety device according to different phases, and allow to explain the operation of the weapon. In particular, FIGS. 3 relate to a GP pistol, in which we observe _:

1. Simple action (figure 3a)

In simple action, the dog 11 is kept in contact with the dog ring 12 at "A" by the action of the return spring 13, this assembly being retained by the trigger 14 in the "armed" position (spring of the dog 22 stretched ) which itself is held by the action of the trigger spring 15.

The cocking lever 17 is pushed up by the action of its spring 20 and retained at the level of its index at "B" by the "safety fast shooting" lever 16, which is locked against the dog at "C ".

With the gun ready to fire, the gunner now has two options.

2. Shooting (Figure 3b) This phase is identical for all weapons using the single action system. The trigger is pressed, which, by the basic principle of the weapon, rotates the trigger 14 on its axis until it comes to abut, just after the release on its index finger in J, this for the purpose to release the dog ring 12, which by the thrust exerted by the spring of the dog 22, drives the dog in "A", which ends its race by violently striking the striker (percussion). During these movements of parts causing the firing, the cocking lever 17 remained blocked by the "fast shooting" lever 16 in "B" which itself remained in the initial position by its new contact in "D" with the dog ring 12. After firing, the dog 11 and dog ring 12 assembly driven by the retraction of the moving parts (slide) is found in the initial single action position (FIG. 3a).

3. Positioning in "fast shooting" position (figure 3c)

If the shooter decides not to use his weapon immediately, he must put his weapon in the safety position, which we will call here, by its specificity, "safety fast shooting". To do this, the weapon being in the single action position (FIG. 3a), it is necessary to push the hammer 11 by exerting a pressure there which will make it pivot from the rear towards the front until the click of the lever of " fast shooting "16 in" E ", which was pushed by the control lever of the cocking lever 17 in" F ", which itself is pushed up by its spring 20. This same push exerted by the 'index of the cocking lever 17 also has the function of blocking the trigger 14 by its contact in "G", and it follows from this that the dog finds itself blocked in the advanced position. The cocking lever 17 being in its high position, its lug can also enter a notch of the slide in "H" and block the latter. 4. Return to single action position

When the shooter decides to use his weapon again, he must put it back in single action position.

Before or during the acquisition of the target, to release the safeties activated during the setting in position "safety fast shooting", the shooter will have to print with the cocking lever 17 a pressure from the top to the bottom until the release of the lever of "fast shooting" 16 by its I-shaped contact, which will have the effect of releasing the active safety devices by the release of the lug "H" from the cocking lever 17 of the slide and by the release of the trigger 14, and thus allowing the return spring 13 to return the dog 11 to the rear position, ready for single action shot (Figure 3a).

Figures 4 show in section the different parts constituting the safety device in different phases, and explain the operation of the weapon. In particular, Figures 4 relate to a P220 series GIS, in which we observe:

1. Single action (FIG. 4a) In single action, the dog 11 is kept in contact with the dog ring 12 at "A" by the action of the return spring 13, this assembly being retained by the trigger 14 in position " armed "(compressed dog spring 22) which itself is held by the action of the trigger spring 15.

The cocking lever 17 is pushed up by the action of its spring 20 and retained against the dog at "B", which prevents it from taking its high position.

With the gun ready to fire, the gunner now has two options.

2. Shooting (Figure 4b)

This phase is identical for all weapons using the single action system, and will be described here for the purpose of outright recall. The trigger is pressed, which, by the basic principle of the weapon, rotates the trigger 14 on its axis in order to release the dog ring 12, which by the thrust exerted by the spring of the dog 22, drives the dog in "A", which ends its race by violently striking the striker (percussion). During these movements of parts causing the shot, the cocking lever 17 remained blocked by the dog 11 and the dog ring 12 at "B".

After firing, the dog 11 and dog ring 12 assembly driven by the retraction of the moving parts (slide) is found in the initial single action position (FIG. 4a).

3. Positioning in "fast shooting" position (figure 4c)

If the shooter decides not to use his weapon immediately, he must put his weapon in the safety position, which we will call here, by its specificity, "safety fast shooting". To do this, the weapon being in the single action position (FIG. 4a), the dog 11 must be pushed by exerting a pressure there which will make it pivot from the rear towards the front until the latch of the lever 'index of cocking lever 17 in "E", which is pushed up by its spring. This same movement of the cocking lever 17 also has the function of blocking the trigger 14 by its contact in "G", and it follows from this that the dog finds itself blocked in the advanced position, trigger 14 locked. The dog 11 obstructing the slide, the latter can not move back.

4. Return to single action position

Before or during the acquisition of the target, to release the safety devices activated when placing in the "safety fast shooting" position, the shooter will have to press the cocking lever 17 from top to bottom until the indexing of the cocking lever index 17, which will have the effect of releasing the active safety devices by unlocking the trigger 14 but also allowing the return spring 13 to return the hammer 11 to the rear position, ready to fire in single action (FIG. 4a), with the passage of the clear slide.

Figures 5 show in section the different parts constituting the safety device in different phases, and explain the operation of the weapon. In particular, FIGS. 5 relate to a COLT 45, in which we observe:

1. Simple action (figure 5a)

By simple action, the dog 11 is kept in contact with the dog ring 12 at "A" by the direct action of the return spring 13, this assembly being retained by the trigger 14 in the "armed" position (dog spring 22 compressed) which itself is held by the action of the trigger spring 15. The cocking lever 17 is pushed up by the action of its spring 20 and retained against the dog at "B", which prevents from taking its high position.

With the gun ready to fire, the gunner now has two options.

2. Shooting (Figure 5b)

This phase is identical for all weapons using the single action system, and will be described here for the purpose of outright recall. The trigger is pressed, which, by the basic principle of the weapon, rotates the trigger 14 on its axis in order to release the dog ring 12, which by the thrust exerted by the spring of the dog 22, causes the dog at "A", which ends its run by violently striking the striker (percussion). During these movements of parts causing the shot, the cocking lever 17 remained blocked by the dog 11 and the dog ring 12 at "B".

After firing, the dog 11 and dog ring 12 assembly driven by the retraction of the moving parts (slide) is found in the initial single action position (FIG. 5a).

3. Positioning in "fast shooting" position (figure 5c)

If the shooter decides not to use his weapon immediately, he must put his weapon in the safety position, which we will call here, by its specificity, "safety fast shooting". To do this, the weapon being in the single action position (FIG. 5a), the dog 11 must be pushed in there by exerting a pressure which will make it pivot from the rear towards the front until the latching of the lever 'index of cocking lever 17 in "E", which is pushed up by its spring. This same movement of the cocking lever 17 also has the function of blocking the trigger 14 by its contact in "G", and it follows from this that the dog finds itself blocked in the advanced position, trigger 14 locked. The cocking lever dog 17 being in its high position, its end enters a notch of the "H" slide and blocks it.

4. Return to single action position

Before or during the acquisition of the target, to release the safety devices activated when putting in the "safety fast shooting" position, the shooter will have to print on the cocking lever 17 a pressure from the top to the bottom until the release of the index of the cocking lever 17, which will have the effect of releasing the active safety devices by the exit from the end of the cocking lever of the slide and by the release of the trigger 14, but also to allow the spring to reminder 13 to return the dog 11 to the rear position, ready to fire in single action (Figure 5a).

The system having a criterion of universality, it is quite obvious that the form of execution relative to the GP (9 mm FN35), to the SIG P220 series, to the Coït 45 and their derivatives is given only by way of illustration and example, and that any other firearm with an interposed dog firing system could have served the same purpose. To do this, the principle of the invention must simply be adapted at the drawing level to the specifics of the weapon in question while keeping the same operating principles, with the aim of withdrawing all or part of the advantages set out in the description of the device of the invention.

In addition, the device of the invention can be produced in the form of a kit for mounting in a weapon. existing or can be part of a new weapon leaving an assembly line.

Among the advantages of the product, one can quote: - the speed of shooting (weapon always ready and carried with cartridge in room in full safety);

- manual arming;

- always relax in the same position;

- trigger stroke identical to that of the single action; - starting weight identical to that of the single action;

- three safety devices activated and deactivated in a single operation;

- the dog is not exposed during the fall of the weapon on the back, therefore no risk of deterioration of the axes of the dog and the trigger as well as their respective hookings and less risk of clutching;

- The modification of existing weapons will be done by means of the device of the invention very simply by any gunsmith, the police and the military, who will be able to modernize quickly and inexpensively their handguns already acquired.

A second object of the present invention aims to propose a right / left-handed magazine stopper, which makes it possible to have a criterion of universality and which, although it is described for a GP pistol (9 mm FN 35), is valid for any pistol having a magazine stopper with horizontal displacement moving on both sides of the weapon. In this case, those skilled in the art can easily adapt the implementation to the specifics of the weapon in question while keeping the same principles of operation with the aim of withdrawing all or part of the advantages described in the description of the product.

According to the second object of the present invention, the right / left-handed magazine retainer can also be produced in the form of a kit to be mounted on an existing weapon or it can be part of a new weapon leaving an assembly line.

FIG. 6 describes such a right / left-handed loader stopper, and in particular the loading and extraction of the loader.

1. Loading the weapon

Insert a magazine into the weapon as specified in the original manual for the weapon in question.

2. Magazine extraction

For a right-handed user, the stopper 1 for the right-handed / left-handed charger does not impose any additional constraint on the shooter, is handled in a completely identical manner and has the same mechanical implications as the original charger stopper. A pressure exerted by the thumb of the right hand, from left to right on the button 3 located at the central level of the left grip, will release the charger.

For a left-handed person, pressure will be exerted by the thumb of the left hand, from top to bottom, on the small lever 2 located at the central level of the right grip, in order to release the magazine.

This lever, taking support on the outside of the carcass from "B ¹ " to "B '", will pull stop 1 from the left to right by its pivoting hooking in the body of the retainer at "A".
