Description

Object of the invention

The present invention relates on a safety device that is mounted on a firearm and is offered in the form of a "kit".

The present invention relates also on a semi-automatic "single action" firearm, like a pistol, which is equipped with this device.

Technological background and state of the art

Gun safety devices that prevent accidental firing of the firearm's cock, are already known. With these safety devices there are two types.

For The single action firearm can be fired in the rear Position will be blocked, but he will fall in case of Affected. This system therefore has the disadvantage that damage on the mechanics of the tap and the trigger or a shot solves when the gun falls down.

Another security device for a firearm of the single action type is described in US-A-5208406, where only the upper part of the tap is manually moved forward to a safety position is placed, which is opening the tap on the firing pin prevented. This is done by exerting pressure on the tap. however the tap is not blocked or locked in this position, which is why for example, there is still a risk in a case.

The firearm can also be of the type Be double action. In this case, the front position is the safety position of the rooster. In the first part of the range of the trigger, the tap is after brought back and in the second part of the course the shot enabled by releasing the tap towards the firing pin. In this case the distance is longer and because of that, the shooting time is all the longer. It can also be observed that a particularly large force is exerted on the trigger got to. On the other hand, the user is concerned about the position of the tap when in doubt when he pulls the trigger. A firearm of this type is described in EP-A1-0550238 described.

Similarly, US-A-4312263 to reduce the force that. be exercised on the deduction has to propose a firearm to cock the cock the blocking of the pusher brought by pushing the tap forward. In this position allows also a safety ring locking the slide. To the To unlock the fuse of the firearm, the tap must go through activity of the trigger (first action) and then the trigger continues depressed to trigger the shot (second action).

Likewise, in the publications US-A-5166458 and EP-A2-0801285 Described protective devices that allow a reduction in force who exercised on the deduction must be in order to cock the firearm. In this case the tap contains a spring pin without locking on the cam of the tap ring locks.

Goals of invention

The present invention has the Task, a quick safety device in the form of a kit to deliver that to a semi-automatic firearm, like one Pistol, can be mounted, as well as the firearm itself said safety device which does not have the disadvantages according to the prior art of technology.

The present invention has in particular that Aim to propose a security device that is essentially is intended for use in weapons with single action mode and so an accurate Shot allows without the position of the trigger between the first shot and the following shots changed and which preserves the protective properties of double-action weapons stay.

An additional goal of the present Invention is to provide such a safety device which, when mounted on the firearm, also reduces the risk of damage the tap and / or the trigger enabled in one case.

It is also the job of present invention to propose a device that the Ignition lock the weapon with a single movement, and so does that Unlocking with a single movement and without pressing the trigger allows to always over to have a firearm ready to fire.

Another object of the invention consists of a safety device in the form of a kit offer, which is fairly simple to address a special Weapon type can be adjusted, whereby the original The structure of a weapon that has already been used is preserved without post-processing of the weapon in question or its. ingredients for the Assembly of the kit would be necessary.

This kit includes a tap in the GP embodiment 11 , a return spring 13 , a pusher 14 , a so-called rapid fire lever 16 , a left cocking lever 17 , possibly a right clamping lever 18 , a tap end piece 21 and a cock ring 12 , with all of these parts except the pusher 14 and the so-called rapid fire lever 16 with a weapon of the type GP are on the same axis. The spring of the tensioning lever is added to these parts 20 , preferably on the right clamping lever 18 or on the left clamping lever 17 is attached, the spring of the tap 22 made with a pen 23 of the Hah end piece on the tap end piece 21 is hooked in, a pen 19 on the right clamping lever 18 is attached and a spring 15 in the pusher that on the pusher 14 suppressed.

In 2 describes the different positions of the individual elements of a pistol in the individual phases of cocking, firing or securing.

3 are sectional drawings of the individual parts that form the safety device in the various phases that serve to explain the functioning of the weapon. The drawings in 3 relate in particular to a GP pistol and show:

1. Single Action ( 3a )

In single action, the tap 11 at "A" by the action of the return spring 13 in contact with the tap ring 12 held; this whole unity is through the pusher 14 in the cocked position (spring of the cock 22 held), the pusher itself by the action of the pusher spring 15 is held.

The tension lever 17 is by his pen 20 pushed up and with his finger through the "Safety Fast Shooting" lever 16 , which is blocked against the tap in "C", held in "B".

The weapon is ready to fire and that Sagittarius has now two options.

2nd shot ( 3b )

This phase is the same for all weapons with single action mode. You pull the trigger, which due to the basic principle of the weapon, the trigger 14 pivots on its axis until it hits its pointer immediately after the detachment in J, with the aim of the cock ring 12 to release that by the of the spring of the cock 22 Exerted pressure moves the tap to "A", which ends its run by a powerful impact on the firing pin (percussion). During these movements of the parts that trigger the shot, the cocking lever remains 17 through the rapid fire lever 16 blocked in "B"; the rapid fire lever itself is due to its new contact with the tap ring 12 remained in its original position in "D".

After the shot there is the tap unit 11 and cock ring 12 , which is carried by the return of the moving parts (sled), again in the single-action starting position ( 3a ).

3. Set the rapid fire position ( 3c )

If the shooter decides not to use his weapon immediately, he must put the weapon in the safety position, which we call "Safety Fast Shooting" due to its special features. Starting from the single-action position of the weapon ( 3a ) the tap has to do this 11 be pressed by exerting a pressure there, which makes him give from the back to the front until the rapid-fire lever 16 snaps into "E"; this was done by the operating finger of the tension lever 17 pressed in "F", which in turn by its spring 20 is pushed up. The same pushing movement of the finger of the tension lever 17 also has the function of the pusher 14 to block by its contact in "G"; this blocks the tap in the advanced position. Because the cocking lever 17 is in its upper position, its locking pin can also engage in "H" in the notch of the slide and block it.

4. Return to the single-action position

If the shooter wants to use his weapon again, he has to bring them back to the single-action position.

Before or during the acquisition of the target, the shooter has to release the fuses that were activated by switching to the "Safety Fast Shooting" position 17 exert pressure from top to bottom until the rapid fire lever 16 disengages through its contact in I, causing the active fuses to exit through the locking pin "H" of the tensioning lever 17 out of the sled and unlocking the handle 14 be released and so the return spring 13 the rooster 11 in the rear, ready to fire for single action ( 3a ) can bring back.

4 are sectional drawings of the individual parts that form the safety device in the various phases that serve to explain the functioning of the weapon. The drawings in 4 relate in particular to a SIG series P220 and show:

1. Single Action ( 4a )

In single action, the tap 11 at "A" by the action of the return spring 13 in contact with the tap ring 12 held; this whole unity is through the pusher 14 in the cocked position (spring of the cock 22 compressed), the pusher itself by the action of the pusher spring 15 is held.

The tension lever 17 is by the spring 20 pushed up and pressed in "B" against the tap, which prevents it from taking the upper position.

The weapon is ready to fire and that Sagittarius has now two options.

2nd shot ( 4b )

This phase is the same for all weapons with a single action system, and is only used here described again as a reminder. You pull the trigger, which due to the basic principle of the weapon, the trigger 14 on its axis swivels the cock ring with the aim 12 to release that by the of the spring of the cock 22 Exerted pressure moves the tap to "A", which ends its run with a powerful impact on the firing pin (percussion). During these movements of the parts that trigger the shot, the cocking lever remains 17 through the tap 11 and the cock ring 12 blocked in "B".

After the shot there is the tap unit 11 and cock ring 12 , which is carried by the return of the moving parts (sled), again in the single-action starting position ( 4a ).

3. Set the rapid fire position ( 4c )

If the shooter decides not to use his weapon immediately, he must put the weapon in the safety position, which we call "Safety Fast Shooting" due to its special features. Starting from the single-action position of the weapon ( 4a ) the tap has to do this 11 be pressed by exerting a pressure there, which allows him to give from the back to the front until the lever of the finger of the tensioning lever 17 snaps into "E"; this is pushed up by its spring. This movement of the tension lever 17 also has the function of the pusher 14 to block by its contact in "G"; this locks the tap in the advanced position, causing the trigger 14 Is blocked. Since the tap is an obstacle for the sled, it cannot slide back.

4. Return to the single-action position

If the shooter wants to use his weapon again, he has to bring them back to the single-action position.

Before or during the acquisition of the target, the shooter has to release the fuses that were activated by switching to the "Safety Fast Shooting" position 17 exert pressure from top to bottom until the finger of the tensioning lever 17 disengages, causing the active fuses by unlocking the handle 14 be released and also the return spring 13 the rooster 11 in the rear, ready to fire for single action ( 4a ) with the released return of the slide.

5 are sectional drawings of the individual parts that form the safety device in the various phases that serve to explain the functioning of the weapon. The drawings in 5 refer in particular to a COLT 45 and show:

1. Single Action ( 5a )

In single action, the tap 11 at "A" through the direct action of the return spring 13 in contact with the tap ring 12 held; this whole unity is through the pusher 14 in the cocked position (spring of the cock 22 compressed), the pusher itself by the action of the pusher spring 15 is held.

The tension lever 17 is by the spring 20 pushed up and pressed in "B" against the tap, which prevents it from taking the upper position.

The weapon is ready to fire and that Sagittarius has now two options.

2nd shot ( 5b )

This phase is the same for all weapons with a single-action system, and is described here again only as a reminder. You pull the trigger, which due to the basic principle of the weapon, the trigger 14 on its axis swivels the cock ring with the aim 12 to release that by the of the spring of the cock 22 Exerted pressure moves the tap to "A", which ends its run with a powerful impact on the firing pin (percussion). During these movements of the parts that trigger the shot, the cocking lever remains 17 through the tap 11 and the cock ring 12 blocked in "B".

After the shot there is the tap unit 11 and cock ring 12 , which is carried by the return of the moving parts (sled), again in the single-action starting position ( 5a ).

Set rapid fire position ( 5c )

If the shooter decides not to use his weapon immediately, he must put the weapon in the safety position, which we call "Safety Fast Shooting" due to its special features. Starting from the single-action position of the weapon ( 5a ) the tap has to do this 11 be pressed by exerting a pressure there, which allows him to give from the back to the front until the lever of the finger of the tensioning lever 17 snaps into "E"; this is pushed up by its spring. This movement of the tension lever 17 also has the function, the pusher 14 to block by its contact in "G"; this locks the tap in the advanced position, causing the trigger 14 Is blocked. Because the cocking lever 17 is in its upper position, its end in "H" engages in a notch in the carriage and blocks it.

4. Return in the single-action position

When the shooter uses his weapon again If he wants to zen, he has to bring it back to the single-action position.

Before or during the acquisition of the target, the shooter has to release the fuses that were activated by switching to the "Safety Fast Shooting" position 17 exert pressure from top to bottom until the finger of the tensioning lever 17 disengages, causing the active safety devices to emerge from the slide and the release of the handle 14 be released and also the return spring 13 the rooster 11 in the rear, ready to fire for single action ( 5a ) can bring back.

Since it is a universal system, it goes without saying that the exemplary embodiment for the GP (9 mm FN35), the SIG series P220, the Colt 45 and their modified forms are for illustration and example only, and that any other firearm that works with an ignition system through an interposed tap could have been used in the same way.

To do this, the principle of Invention in the drawing of the peculiarities of the subject Weapon can be adjusted while maintaining the same operating principles are going to take all or part of the benefits outlined in the description of the Device according to the invention were shown to achieve.

In addition, the device according to the invention be offered in the form of a kit that fits into an existing Weapon can be mounted or can become part of a new weapon, that leaves the assembly line.
