Description

Firearm provided with a device Quick security and safety kit kit.

Object of the invention

The present invention relates to a device safety to be mounted on a firearm, which Presents in kit form.

The present invention also relates to a semi-automatic single-acting firearm such as a pistol, equipped with said device.

Technological background and state of the art

Security devices are already known for firearms that prevent involuntary hammer percussion of the weapon These security devices are of two types.

For firearms of the type of action simple, the hammer can be locked in the rear position, which leaves you exposed in case of fall. This device suffers from both of the inconvenience of causing degradation in the mechanisms  at the level of the hammer and the trigger or of allowing the firing untimely of a bullet as a result of a fall.

Other safety device for firearms of the type of simple action is described in the document US-A-5208406, in which only the top of the hammer is turned manually on its axis forward in a safe position, which prevents it hit the firing pin. This is obtained by exerting a pressure on the hammer However, the hammer is not locked in this position, whereby a risk remains, for example in case of fall

The firearm can also be equally type of double action. In this case, the security position of the Hammer is the forward position. The first part of the race of the trigger takes the hammer back and the second part of this race allows firing freeing the hammer forward towards the firing pin. In this case, the race is longer, and so So much, also the shooting time. It is also observed that the effort to exert on the trigger is particularly important. On the other hand, there remains a doubt for the user on the position of the hammer when the trigger is pressed. A firearm of this type is described in the document EP-A1-0550238.

It has also been proposed in the document US-A-4312263, with a view to reducing the effort to exert on the trigger to arm the hammer, a firearm in which trigger lock is triggered pushing the hammer forward. In this position, a ring of safety also allows to lock the slide. For Unlock firearm insurance, first of all you must arm the hammer by moving the trigger (first action) and to continue to press on it to trigger the shot (second action).

In the same way, the documents US-A-5166458 and EP-A2-0801285 describe devices of protection that allow to reduce the effort to exert on the trigger to arm the firearm. In this case, the hammer It contains a spring button that is locked by a ratchet on the cams of the hammer ring.

Object of the invention

The objective of the present invention is provide a quick safety device in kit form to be mounted on a semi-automatic type firearm such like a gun, and also provide the firearm itself same endowed with said security system, without these presenting the drawbacks of the state of the art.

The present invention particularly seeks propose a security device essentially intended to be used on simple action weapons, thus allowing to obtain a precise shot that does not require a change of trigger position between the first shot and the following, while maintaining double-acting weapons protection qualities.

A complementary objective of this invention is to provide said security device that, mounted on the firearm, also allow to reduce the risk of damage to the hammer and / or the trigger in case of drop.

Another objective of the present invention is propose a device that, with a single movement, allows block the firing of the weapon, and also, with a single movement, allow to unlock the system, without pressing the trigger, leaving thus the weapon in a "ready to fire" configuration.

Another objective of the present invention is propose a safety device in the form of a kit that suits with relative ease to a particular type of weapon, keeping always the initial structure of a firearm already in service, and this without having to resort to a complementary machining of the weapon or of the parts that compose it to be able to assemble the kit.

Main characteristic elements of the invention

The present invention relates to a device of security destined to a semi-automatic firearm of simple action that has a trigger control system by a interposed hammer, presented in kit form that can be originally mounted on the firearm or adapts to a weapon of fire that is already in service, comprising a hammer that crashes into the firing pin of the weapon at the time of shooting, a hammer ring cooperating with the hammer, a trigger operated by the trigger of the weapon and that, at the time of shooting, allows you to release the hammer ring, a hammer tail that comprises the hammer spring that is compressed to assemble the hammer and that, at the time of shooting, pushes the hammer ring so that the hammer hits the firing pin, a lever of reset that is manually operated to release the locks assets by unlocking the trigger, the hammer and the slide of the weapon, a return spring to send the hammer back in armed position ready to shoot in action simple, characterized in that it comprises a lever spring of reset, also a pin fixed on the reset lever and a trigger spring and because the hammer spring is hooked by middle of a pin to the hammer tail.

Preferably, the weapon comprises a lever of fast shooting that can release the reset lever, the hammer and the hammer ring

The present invention also relates to the weapon semi-automatic type of fire such as a gun or possibly a revolver, which has a firing mechanism by hammer capable of colliding with a firing pin and, through of a trigger operated by the trigger, distributes of a cartridge either in a slide in the case of a gun, or of a drum in the case of a revolver, and comprising the safety device as described above.

Preferably, the reset levers serve also to suppress the firearm insurance causing the return in hammer assembly position and unlocking the Sliding, trigger and / or trigger.

Description of various preferred embodiments of the invention

The fast security device presented in kit form and then referred to as "safety fast shooting ", can be mounted originally on a firearm semi-automatic type such as a gun or being susceptible to be adapted from a kit on a weapon already in service. In In the latter case, the modification will be made very simply for any gunsmith using said kit corresponding to the type of planned weapon, remaining the rest of the weapon identical to the weapon original.

The security device, particularly simple, fits any semi-automatic type firearm without modifying the shooting characteristics of said weapon.

Several preferred embodiments of the Present invention are described below for three weapons semiautomatic particular, which are the GP, Colt 45 and the GIS P220 series.

Figure 1 represents an exploded view of the different parts that make up the kit to be assembled and that constitute the rapid security device intended to be installed on a GP gun. This kit comprises, in the GP execution form, a hammer 11, a return spring 13, a trigger 14, a lever called "fast shooting" 16, a reset lever left 17, possibly a right reset lever 18, a hammer tail 21 and a hammer ring 12, all meeting these parts, except the trigger 14 and the lever called "fast shooting" 16, on the same axis in the case of a weapon GP type. To these pieces are added the spring of the lever of reset 20 which is preferably fixed on the reset lever right 18 or left 17, the hammer spring 22 that engages by means of a pin 23 from the tail of the hammer to the tail of the hammer 21, a pin 19 being fixed on the lever of right rearmament 18 and a spring 15 on the trigger 14 that rests on the trigger 14.

Figures 2 describe the different positions of several organs of a gun according to the different phases of armed, shooting or security.

Figures 3 represent in section the different parts that constitute the safety device according to different phases, and allow to explain the operation of the weapon. Figures 3 refer in particular to a GP gun, in which is observed:

1. Simple action (figure 3a)

In simple action, hammer 11 is held in contact with hammer ring 12 in "A" by means of the return spring action 13, this assembly being retained by trigger 14 in "armed" position (hammer spring 22 tensioned) in turn by means of the trigger spring section fifteen.

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

When the weapon is ready for firing, it They offer the shooter two options.

2. Shot (figure 3b)

This phase is identical for all weapons that They use the simple action system. The trigger is pressed, what which, according to the basic principle of the weapon, rotates the trigger 14 on its axis until it crashes, just after unlocking on its index in J, and this in order to release the ring of the hammer 12, which thanks to the thrust exerted by the spring of the hammer 22, drag the hammer into "A", which ends its career crashing violently against the firing pin (percussion). During some displacements of the pieces that produce the shot, reset lever 17 remains locked by the lever "fast shooting" 16 in "B" in turn locked in the initial position for your new "D" contact with the ring of the hammer 12.

After the shot, the set formed by the hammer 11 and its ring 12 is dragged by the recoil of the moving parts (sliding) returns to the starting position simple (figure 3a).

3. Commissioning "fast shooting" (figure 3c)

If the shooter decides not to use his weapon immediately, you must put it in a safe position, which we will call next, due to its specificity, "safety fast shooting. "For that, the gun being in action position simple (figure 3a), you have to push the hammer 11 exerting a pressure that will turn you from back to front until interlocking the lever of "fast shooting" 16 in "E", which has been pushed by the reset index of the reset lever 17 in "F", which is in turn pushed up by the spring 20. This same thrust exerted by the lever index of reset 17 also by function lock trigger 14 by means of his contact in "G", and it follows that the hammer is is locked in forward position. Being the lever of rearm 17 in its high position, its ram can also enter a notch of the "H" slide and block the latter.

4. Return to the simple action position

When the shooter decides to reuse his weapon, you must put it back in simple action position.

Before or during the target, to release the safety activated by the "safety fast" setting shooting ", the shooter must print to the reset lever 17 a pressure from top to bottom until the unlocking of the "fast shooting" lever 16 for its "I" contact, what which will release the active insurance by the exit of the ram "H" of the reset lever 17 of the slide and by unlocking the trigger 14, and will therefore allow the return spring 13 send hammer 11 back to its back position, ready for simple action shot (figure 3a).

Figures 4 represent in section the different parts that constitute the safety device in different phases, and allow to explain the operation of the weapon. In particular, figures 4 refer to a P220 series GIS, in which is observed:

1. Simple action (figure 4a)

In simple action, hammer 11 is held in contact with hammer ring 12 in "A" by the action of return spring 13, this assembly being held in position "armed" (hammer spring 22 compressed) by trigger 14 in turn maintained by the trigger spring 15.

The reset lever 17 is pushed up by the action of its spring 20 and held against the hammer in "B", which prevents him from taking his high position.

When the weapon is ready for firing, it They offer the shooter two options.

2. Shot (figure 4b)

This phase is identical for all weapons that they use the simple action system and will be described here as pure and simple reminder. The trigger is pressed, which, according to the basic principle of the weapon, rotates the trigger 14 on its axis to release the hammer ring 12, which thanks to the thrust exerted by the hammer spring 22, drag the hammer in "A", who ends his career crashing violently against him firing pin (percussion). During these movements of the pieces that produce the trip, the reset lever 17 remains locked by hammer 11 and by hammer ring 12 in "B".

After the shot, the set formed by the hammer 11 and ring 12 dragged by the recoil of the moving parts (sliding) stays in the starting position simple (figure 4a).

3. Commissioning "fast shooting" (figure 4c)

If the shooter decides not to use his weapon immediately, you must put it in a safe position, to which we will call next, due to its specificity, "safety fast shooting ". To do this, the weapon being in action position simple (figure 4a), you have to push the hammer 11 exerting a pressure that will turn it on its axis from back to front until interlocking of the index lever of the reset lever 17 in "E", which is pushed up by its dock. East same sliding of the reset lever 17 also has as function of blocking trigger 14 by its "G" contact, and of it turns out that the hammer is locked in position forward, with trigger 14 locked. How hammer 11 prevents the movement of the slide, it cannot go back.

4. Return to the simple action position

When the shooter decides to reuse his weapon, you must put it back in simple action position.

Before or during the target, to release the safety activated by the "safety fast" setting shooting ", the shooter must print to the reset lever 17 a pressure from top to bottom until the index unlocks of the reset lever 17, which will release the active locks by  trigger 14 release but will also allow the spring return 13 send hammer 11 back to its rear position, ready for shooting in simple action (figure 4a), with the step Free for the slide.

Figures 5 represent in section the different parts that constitute the safety device according to different phases, and allow to explain the operation of the weapon. In particular, figures 5 refer to a COLT 45, and in them it is noted :

1. Simple action (figure 5a)

In simple action, hammer 11 is held in contact with hammer ring 12 in "A" per action direct from the warning dock 13, this set being retained in "armed" position (hammer spring 22 compressed) by the trigger 14, in turn held by trigger spring 15.

The reset lever 17 is pushed up by the action of its spring 20 and held against the hammer in "B", which prevents him from taking his high position.

When the weapon is ready for firing, it They offer the shooter two options.

2. Shot (figure 5b)

This phase is identical for all weapons that they use the simple action system, and it will be described here as Pure and simple reminder. The trigger is pressed, which, according to the basic principle of the weapon, rotate the trigger 14 on its axis to release the hammer ring 12, which thanks to the thrust exerted by hammer spring 22, drag the hammer in "A", which ends his career violently crashing into the firing pin (percussion). During these displacements of pieces that triggering, reset lever 17 remains locked by the hammer 11 and by the hammer ring 12 in "B".

After the shot, the set formed by the hammer 11 and ring 12 dragged by the recoil of the moving parts (sliding) is in initial position action simple (figure 5a).

3. Commissioning "fast shooting" (figure 5c)

If the shooter decides not to use his weapon immediately, you must put it in a safe position, to which we will call next, due to its specificity, "safety fast shooting ". To do this, the weapon being in action position simple (figure 5a), you have to push the hammer 11 exerting a pressure that will turn it on its axis from back to front until interlocking of the index lever of the reset lever 17 in "E", which is pushed up by its dock. East same movement of the reset lever 17 also has for function lock trigger 14 by its "G" contact. And of it turns out that the hammer is locked in position forward, with trigger 14 locked. Being the lever of rearm 17 in its high position, its end enters a notch of the sliding in "H" and blocks the latter.

4. Return to the simple action position

When the shooter decides to reuse his weapon, you must put it back in simple action position.

Before or during the target, to release active insurance during the "safety fast" position shooting ", the shooter must print to the reset lever 17 a pressure from top to bottom until the index unlocks of the reset lever 17, which will release the active locks by the outlet of the end of the reset lever of the slide and by unlocking trigger 14, but it will also allow the return spring 13 send the hammer 11 to its rear position, ready for shooting in simple action (figure 5a).

Having the system a universal criterion, it is It is clear that the embodiment relative to the GP (9 mm FN35), when SIG P220 series, Colt 45 and its derivatives are only given as illustrative and example, and that any other firearm with a hammer firing system could have served as the same way.

For this, the principle of the invention must simply be adapted at the design level to the characteristics of the weapon while keeping the same principles of operation, in order to withdraw all or part of the advantages set forth in the description of the device of the invention.

In addition, the device of the invention can be made in kit form to mount it on an existing weapon or can be part of a new weapon that comes out of the chain of mounting.
