Firearm provided with removable trigger.

The present patent application relates to a firearm, of the type of shotguns, guns, and similar weapons, provided with removable trigger.

The present invention has been devised in order to definitely overcome a serious problem that refers to the storage of firearms in domestic environments.

In such a circumstance, firearms can be also accessible to non-expert users who are not aware of the risks related with them, such as children or elderly people of unsound mind.

Misuse of firearms by these individuals can become extremely dangerous if the person authorized to use said weapons has stored them loaded, that is to say ready to shoot.

On the other hand, such a situation can be extremely dangerous also if the firearm is handled by an expert user who is not aware, or has forgotten that the firearm is loaded. Obviously, in such a case, the risk is that an accidental shot can be fired by the loaded firearm, causing extremely serious risks for the safety of the individual who is handling the gun or of those in the surroundings.

It must be noted that the risk of such a dangerous situation has led manufacturers of firearms to provide them with safety bolt, that is to say a device able to lock the trigger to prevent accidental shooting.

In spite of such a device, however, accidents with firearms occur with alarming frequency, evidently because safety bolts are not activated in some cases, perhaps for negligence of the person responsible or because, in other cases, the unauthorized person who handles the firearm manages, either willingly or accidentally, to release the safety bolt that had been previously activated.

The specific purpose of the present invention is to devise a firearm that is able to prevent, beyond all reasonable risks, accidental shooting when it is stored loaded.

Starting from the fact that traditional safety bolts can be deactivated also by unauthorized persons (and therefore their efficacy in terms of safety is rather aleatory), it has been devised to provide firearms with a more drastic measure, which consists in a removable trigger.

So if the person responsible for storing the firearm decides to store it loaded, he can decide to remove the trigger and store it remotely, possibly in a closed place without free access for persons who are not authorized to use the firearm. Evidently, even if the firearm falls in possession of unauthorized persons, they would not be able to cock and shoot without the trigger.

Moreover, the removal of the trigger from the firearm can be a positive measure also for the safety of individuals who are expert in firearm handling.

In fact, if the user wants to bring back the firearm to operating condition, he must reassemble the trigger.

So, if the user must reassemble the trigger, he will probably remember to check whether the firearm is loaded.

He will remember that the original decision to remove the trigger from the firearm was taken because the firearm was stored loaded, that is to say in a potentially dangerous situation.

For purposes of clarity, the description of the invention continues with reference to the enclosed drawing, which is intended for purposes of illustration only and not in a limiting sense, wherein:

- figure 1 is a side view of the trigger area of a firearm, with trigger in operating position;

- Figure 2 is a cross-sectional view with a vertical plane of figure 1 ;

- Figure 3 is the same as figure 2, except for it shows the trigger during uncoupling from the firearm.

Referring to Fig. 1 , it must be noted that the firearm of the invention (1 ) is normally provided with a trigger (2) contained inside an eyelet (3) in which the user must insert his index finger in order to actuate the trigger and shoot. As mentioned above, the peculiarity of the firearm of the invention (1 ), which is otherwise provided with a completely traditional structure, consists in the fact that it is provided with a removable trigger (2).

More precisely, said trigger (2) ends on top with a small cylindrical head (2a) with external thread, basically consisting in a threaded pin. Said threaded pin (2a) is helicoidally coupled inside a corresponding threaded cylindrical seat (4a) obtained on the cock (4) contained inside the body of the firearm (1 ).

In order to obtain said helicoidal coupling, it is necessary to have a slot (4b) through which the threaded head (2a) of the trigger (2) penetrates inside the body of the firearm and reaches the seat (4a) obtained on the cock (4).

In any case, when the trigger (2) is firmly coupled with the cock (4), the trigger (2) can normally actuate the cock (4) and shoot, as shown in figures 1 and 2.

In order to prevent the firearm from shooting, the trigger (2) can be unscrewed from the seat (4a) and removed from it from up down.

Reference is made to Fig. 3, which shows how the removal of the removable trigger (2) is favored by the possibility, provided in the firearm of the invention (1 ), to open the lower-horizontal section (3a) of the eyelet (3), which is suitably provided with an articulated structure. As shown in said figure, the eyelet (3) of the firearm of the invention

(1 ) is composed of two sections, that is to say a fixed front-vertical section (3b) and a mobile lower-horizontal section (3a).

The front-vertical section (3b) is usually incorporated in the structure of the firearm (1 ) and ends with a small hole in lower position. The lower-horizontal section (3a) of the eyelet (3) is provided with similar holes at the two ends.

The connection between the two sections (3a, 3b) of the eyelet (3) can be obtained by means of a screw with horizontal axis (V1 ) after achieving perfect alignment - in order to favor the insertion of the screw (V1 ) - between the hole under the fixed section (3b) and the hole in the front end of the mobile section (3a).

The hole provided at the back end of the mobile section (3a) of the trigger (3) is designed to be disposed in perfect alignment condition with a similar hole provided in the centre of an ear (5) that protrudes edgeways on the front of the firearm handle.

In such a position the mutual connection of the two aligned holes can be obtained by means of a second through screw (V2).

Until the second screw (V2) is maintained in operating position, the eyelet (3) maintains its structural continuity, as shown in Figs. 1 and 2.

Nevertheless, when the user wants to remove the removable trigger (2) by pulling it downwards, thus eliminating the obstacle represented by the lower-horizontal section (3a) of the eyelet (3), it is simply necessary to remove the second screw (V2) and slightly loosen the first screw (V1 ).

In this way the back end of the mobile section (3a) of the eyelet (3) is uncoupled from the anchoring ear (5) and rotates downward around the pivoting point represented by the first screw (V1 ) that ensures connection, although not very rigidly, between the front end of the mobile section (3a) and the lower end of the fixed section (3b) of the eyelet; this condition is expressly shown in Fig. 3.

In order to bring the firearm back to its operating condition shown in Fig. 1 , it is simply necessary to repeat the aforementioned operations in reverse order, that is to say replace the trigger (2) in the cock (4) and restore continuity of the articulated structure of the eyelet (3).

Finally, it must be noted that, while still falling within the scope of the present invention, a different solution can be adopted to free a passage under the trigger (2) that is useful to favor coupling and uncoupling from the cock (4).

For instance, fast-coupling means could be provided at the ends of the eyelet (3) to create stable connection with retention means provided on the body and handle of the firearm of the invention, and also favor rapid detachment of the entire eyelet (3).
