Description

FIREARMS HAVING A FAST SAFETY DEVICE AND
SAFETY DEVICE IN KIT
Objects of the invention The present invention relates to a weapon semi-automatic single action type fire such as pistol, fitted with a rapid safety device.
The present invention also relates 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 teclLn ~ q ~ g Security devices are already known for a firearm preventing the unintended percussion of the gun dog. These safety devices are two types.
For single action type firearms, . the dog can be locked in the rear position, which nevertheless exposes it in the event of a fall. This system presents therefore the disadvantage of causing degradations in the dog and trigger mechanisms or the inadvertent departure of a bullet during a fall of the weapon.
Another safety device for handgun

2 single action type fire is described in the document US-A-5208406, in which only the upper part of the dog is manually rotated forward in a safety position which prevents it from striking the striker. This is done by pressing the dog. However, the dog is not blocked or locked in this position which allows to remain ûn risk for example during a fall.
The firearm can also be of the type double action. In this case, the safety position of the dog is the forward position. The first part of the trigger run causes the dog backwards and the second part of the race allows you to shoot by releasing the dog forward towards the striker. In this case stroke is longer, and therefore the shooting time is all the more important. We also observe that the effort to apply on the trigger is particularly important.
On the other hand, there remains a doubt for the user on the position of the dog when it pulls the trigger. A weapon to fire of this type is described in document EP-A1-0550238.
It has also been proposed, with a view to reducing the effort 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 forward. In this position, a safety ring also allows you to lock the slide. For unlock the safety of the gun it takes everything first arm the dog by acting on the trigger (first action) and then continue to press it to trigger the shot (second action).
Likewise, documents US-A-5166458 and EP-A2-0801285 describe devices for WO 98! 51984 PCT / BE98 / 00069

3 protection which reduces the effort to be applied on the trigger to cock the gun. In this case, the dog contains a snap spring plunger 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 assembled on a semi-automatic type firearm such as a pistol, as well as the firearm itself comprising said security device, which would not exhibit the disadvantages of the state of the art.
The present invention aims more particularly to offer a safety device intended primarily for use on handguns simple action, allowing to obtain a precise shot which does not require a change of trigger position between the first and subsequent shots while holding the protection qualities of double action weapons.
A purpose complementary to this invention aims to provide such a security device which, mounted on the gun, also reduces the risks of damage to the dog and / or the trigger fall.
Another object of the present invention is to propose a device which, with a single movement, allows to lock the firing of the weapon, and which likewise, by a single movement, releases the lock, this . without pressing the trigger, in order to place the firearm in a configuration ready to fire.
Another object of the present invention is to offer a safety device in kit form, which WO 98/5198

4 PCTBE98 / 00069 relatively easy to adapt to a type of weapon particular while keeping the initial structure of a firearm already in service, without having to resort to a additional machining of the weapon concerned or parts la component for mounting the kit.
Main characteristic features of the invention A first object of the present invention is relates to a single semi-automatic type firearm action with a firing system per dog interposed such as a pistol or possibly a revolver which, by means of a trigger actuated by the trigger, dispenses the cartridge either in a slide in the case of a pistol, either in a barrel in the case of a revolver having means of blocking of the dog when it is placed in the forward position thus causing the safety of the gun.
These blocking means comprise at least one cocking lever which undergoes automatic latching when the dog is placed in the front position.
Preferably, this snap of the lever also allows you to lock the slide, who can no longer retreat, and possibly block the trigger and / or trigger.
Particularly advantageously, the blocking means also serve to remove security of the firearm by causing it to return to the armed position of the dog and unlocking the slide if necessary, the trigger and / or trigger.
Another object of the present invention is also relates to a semi-firearm automatic single action with a setting system by dog interposed such as a pistol or possibly a revolver which, via a trigger actuated by trigger, dispenses

5 of 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 trigger to unlock or unlock the dog in the front position, the slide, trigger and / or trigger.
A third object of the present invention relates to a safety device presented in the form kit for a semi-automatic type firearm with an interposed dog firing system such as a pistol or possibly a revolver, which could be originally mounted on the gun or that fits on the firearm already in service, characterized in that it includes a dog striking the striker of the weapon during the shooting, a dog ring cooperating with the dog, a trigger actuated by the trigger of the weapon and which, when shot, frees the dog's ring, a tail dog comprising the spring of the dog which is compressed to arm the dog and who, when firing, pushes the ring dog to strike the dog against the striker, a cocking lever possibly left and / or right which is manually operated to release the safety devices activated by unlocking the trigger, the dog and the slide, a return spring to send the dog back rear in 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 security device also includes an arming lever spring which

6 preferably fixed on the cocking lever is straight, either left, a dog spring which hooks by means of a pin to the tail of the dog as well as a pin attached to the cocking lever and a trigger spring.
A final object of the present invention is relates to a right / left-handed charger retainer intended a semi-automatic type firearm having a retainer of horizontally moving loader moving sideways and other side of the weapon including a button located at the level center of the left hook to release the magazine by pushing said preference button from the left towards the right and a small lever located at the central level of the right hook to release the magazine by pushing said lever preferably from top to bottom.

To these parts are added the spring of cocking lever 20 which preferably attaches to the cocking lever right 18 or left 17, the spring of the dog 22 which is hooked by means of a pin 23 of the dog tail on dog tail 21, 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 different arming, firing or security phases.
Figures 3 show in section the _ -______ ~ _ _ ._.__. __ _ ._ ~ __.____-__.

9 different parts constituting the safety device in different phases, and explain the operation of the weapon. In particular, Figures 3 are relate to a GP pistol, in which we observe.
1 Sir ~ ole action (Figure 3a ~
In a 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 "armed" position (dog spring 22 stretched) which itself is maintained by the action of the spring of trigger 15.
The cocking lever 17 is pushed towards the high by the action of its spring 20 and retained at the level of his index in "B" by the lever of "safety frit shooting"
16, which is blocked against the dog at "C".
With the gun ready to fire, two options now available to the shooter.
2 Shot (Figure 3b) This phase is identical for all weapons using the single action system. We press it trigger, which, by the basic principle of the weapon, makes rotate trigger 14 on its axis until it come abut, just after the dropout on his index finger in J, this in order to release the dog ring 12, which by the thrust exerted by the spring of the dog 22, causes the dog in "A", which finishes its run by striking violently the striker (percussion). During these parts movements causing the firing, the cocking lever 17 remained blocked by the "fast shooting" lever 16 in "B" which is itself remained in the initial position by its new contact in "D" with the dog ring 12.

After the shot, the dog 11 and dog ring I2 assembly driven by the backward movement of the moving parts (slide) found in the initial single action position (Figure 3a).
5 3 Positioning in "fast shooting" position (figure 3c) If the shooter decides not to use his weapon immediately, he must put his weapon in position security, which we will call here, by its specificity, "safety fast shooting". To do this, the weapon

10 being in the single action position (FIG. 3a), it is necessary to push the dog 11 by exerting a pressure which will make it pivot from rear to front until the "fast shooting" lever 16 in "E", which was pushed by the cocking lever control index 17 at "F", which itself is pushed upward by its spring 20. This same thrust exerted by the index of the cocking lever 17 a also for the function of blocking the trigger 14 by its contact in "G", and it follows from this that the dog found stuck in the advanced position. The cocking lever 17 being in its high position, its lug can also enter a notch of the "H" slide and block this last.
4. Return to single action position When the shooter makes the decision to do again using his weapon, he must put it back in single action position.
Before or during target acquisition, to release the safety devices activated during the "safety" position fast shooting ", the shooter will have to print with the lever arming 17 a pressure from the top down to the release of the fast shooting lever 16 by its contact in I, which will have the effect of releasing the

11 active safety devices by the release of the "H" lug of the lever arming 17 of the slide and by unlocking the trigger 14, and thus allow the return spring 13 return the dog 11 to the rear position, ready to fire in simple action (Figure 3a).
Figures 4 show in section the different parts making up the safety device in different phases, and explain the operation of the weapon. In particular, Figures 4 are relate to a P220 series GIS, in which observe.
1. SimW e action (figure 4a) In a 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 "armed" position (hammer spring 22 compressed) which itself is maintained by the action of trigger spring 15.
The cocking lever 17 is pushed towards the high by the action of its spring 20 and retained against the dog in "B", which prevents it from taking its high position.
With the gun ready to fire, two options now available to the shooter.
2 Shot (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. We press it trigger, which, by the basic principle of the weapon, makes pivot the trigger 14 on its axis in order to release

12 the dog ring 12, which by the thrust exerted by the spring of the dog 22, leads the dog to "A", which finishes its race by violently striking the striker (percussion).
During these shifts of parts resulting in firing, the cocking lever 17 remained blocked by the dog 11 and the dog ring 12 in "B".
After firing, the dog 11 and ring assembly dog 12 driven by the recoil of moving parts (slide) is in the initial position single action (Figure 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 position security, which we will call here, by its specificity, "safety fast shooting". To do this, the weapon being in the single action position (figure 4a), it is necessary push the dog 11 by exerting a pressure which will make it pivot from rear to front until the lever of the index of the cocking lever 17 at "E", which is pushed up by its spring. This same displacement of the cocking lever 17 also has the function of blocking the trigger 14 by its contact in "G", and it results from this that the dog is stuck in the forward position, trigger 14 locked. Dog 11 obstructing the slide, it cannot move back.
4 Return to, ~ single action position When the shooter makes the decision to do again using his weapon, he must put it back in single action position.

13 to release the safety devices activated during activation "safety fast shooting" position, the shooter must print to the cocking lever 17 a pressure from the top towards the. low until the arming lever index is released 17, which will have the effect of releasing the active safety devices by unlocking the trigger 14 but also allowing return spring 13 to return the dog 11 to position rear, ready to fire in single action (Figure 4a), with the clear passage of the slide.
Figures 5 show in section the different parts making up the safety device in different phases, and explain the operation of the weapon. In particular, Figures 5 are relate to a COLT 45, in which we observe.
1. Simple action (figure 5a) In a single action, the dog 11 is kept in contact with the dog ring 12 at "A" by the action direct return spring 13, this assembly being retained by the trigger 14 in the "armed" position (dog spring 22 compressed) which itself is maintained by the action of trigger spring 15.
The cocking lever 17 is pushed towards the high by the action of its spring 20 and retained against the dog in "B", which prevents it from taking its high position.
With the gun ready to fire, two options now available to the shooter.
2. Shooting (Figure 5b) This phase is identical for all

14 weapons using the single action system, and will be described here for the purpose of outright recall. We press it trigger, which, by the basic principle of the weapon, makes pivot 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, leads the dog to "A", which finishes its race by violently striking the striker (percussion).
During these movements of parts leading to the firing, the cocking lever 17 has been blocked by the dog 11 and the dog ring 12 in "B".
After firing, the dog 11 and ring assembly dog 12 driven by the recoil of moving parts (slide) is in the initial position single action (Figure 5a).
~ Positioning in "fast shootincy" position (figure 5c) If the shooter decides not to use his weapon immediately, he must put his weapon in position security, which we will call here, by its specificity, "safety fast shooting". To do this, the weapon being in single action position (figure 5a), it is necessary push the dog 11 by exerting a pressure which will make it pivot from rear to front until the cocking lever index of cocking lever 17 at "E", which is pushed up by its spring. This same displacement of the cocking lever 17 also has the function of blocking the trigger 14 by its contact in "G", and it results from this that the dog is stuck in the forward 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 When the shooter makes the decision to do 5 again using his weapon, he must hand it over single action position.
Before or during the acquisition of the target, to release the safety devices activated during activation "safety fast shooting" position, the shooter must print 10 to the cocking lever 17 a pressure from the top to the bottom until the arming lever index is released 17, which will have the effect of releasing the active safety devices by the exit of the end of the cocking lever of the slide and by unlocking the trigger 14, but also

15 to allow the return spring 13 to return the dog 11 in rear position, ready to fire in single action (Figure 5a).
The system having a criterion of universality, it is obvious that the form of execution relating to the GP
(9 mm FN35), SIG P220 series, Colt 45 and their derivatives is given for illustration only and example, and that any other firearm having an interposed dog firing system could have serve in the same way.
To do this, the principle of the invention simply needs to be adapted at the drawing level to specifics of the weapon in question while keeping the same operating principles, in order to remove all or part of the advantages described in the description of the device of the invention.
