The invention refers to gun mechanics and intended for protection against unauthorized shooting of firearms, in particular, for prevention of assassination attempts of instructors or suicide attempts in shooting galleries and ranges, for prevention of casualties as a result of unsafe handling of guns in shooting galleries and ranges; as well as for limitation of gun use by unauthorized persons.

Safety device for firearms is known as per patent RU 2458306 including the actuating mechanism configured for engagement with mechanical parts of the firearm to prevent and/or allow action thereof; and the control unit operatively connected with the actuating mechanism, wherein the control unit comprises the transmitter-receiver interacting with external certification means actuated by authorized user for signal exchange with safety device for encoded remote control of the actuating mechanism. Additionally, the actuating mechanism comprises the electric motor with shaft operatively connected with the control unit; the cap sliding inside the firearm and engaged with mechanical parts of the firearm; and the motion conversion device connected with the motor and the said cap converting rotational motion from the motor into progressive motion of the cap.

The known device makes usage of firearms possible only by authorized persons, but it does not allow prevention of shooting in inadmissible direction or at the specified intervals. Moreover, usage of such device requires firearm modification.

There is the safety system for hand firearms known as per patent RU 2572942 including the hand firearm having a barrel, a chamber for cartridge arranged at the rear end of barrel, a mechanical arrangement for cartridge inflammation, as well as an electronic device with time sensor. The time sensor is configured for setting initial countdown and mechanical locking of mechanical arrangement for cartridge inflammation after the specified time interval. The safety system also comprises a separate device independent of hand firearm, by means of which the electronic device time sensor is set back to initial time.

Such system allows readiness for usage of hand firearm only within the time interval specified by the authorized user.

However, along with the aforementioned device as per patent RU 2458306, this system does not allow prevention of the possibility to shoot in inadmissible direction and also requires modifications of firearms.

The firearm controller as per patent RU 2735191 is the closest variant to the invention configured for remote locking/unlocking of the firearm trigger and including actuating

SUBSTITUTE SHEETS (RULE 26) mechanism, control unit, remote-controlled mechanism for mounting/removal of the controller from firearms, body with projections, on which the curved lever for locking of firearm trigger in forward most position is mounted. Control unit is connected to the electromagnet and the controller mounting/removal mechanism by means of electric wires, and the electromagnet is configured to interact with the controller mounting/removal mechanism and the actuating mechanism.

The known device allows increase of safety level at sufficient multipurposeness due to the possibility of its mounting at different weapon systems.

But such device requires remote participation of operator and has complex structure, which is almost impossible to arrange on short firearms. Moreover, in the known device, the stopper is pushed by the trigger decreasing operation reliability due to possible jamming.

The problem solved by means of the invention is development of a system allowing blocking of shooting possibility in case a firearm is pointed away from the aim and not requiring manufacturing of purpose-designed weapon or remaking of the existing weapon systems for it.

The said problem is solved in the remote locking/unlocking system for the firearm trigger consisting of the actuating mechanism configured for mounting on firearms and comprising the trigger creep limiter, control and power unit connected with the actuating mechanism by means of electric wires, and wireless communication means between the actuating mechanism and the control and power unit, wherein the actuating mechanism is configured for locking of the trigger creep limiter upon signal from the control and power unit.

The actuating mechanism according to the invention is configured for mounting on the firearm trigger bow and the trigger creep limiter is designed as a plate configured for sliding along the trigger bow under the trigger, moreover, this plate has a recess for free trigger creep, a stopper for the trigger on one end and a connecting element for connection with the actuating mechanism lever on the other end; and the actuating mechanism comprises locking means of the said lever.

Technical result of such system embodiment is locking of the trigger in case the firearm is pointed away from the aim providing the possibility to mount the actuating mechanism on any type of firearms without modification thereof.

Preferably, wireless communication means are designed as a receiver and a transmitter of infrared emission, one of which is provided in the actuating mechanism, and the other one is connected with the control and power unit. Additionally, the actuating mechanism is configured for locking of the lever connected with the creep limiter in case no infrared emission is detected by the receiver.

SUBSTITUTE SHEETS (RULE 26) Infrared emission transmitter may be connected with the power and control unit and the infrared emission receiver may be located in the actuating mechanism and be of directional type, or the infrared emission transmitter may be located in the actuating mechanism and be of directional type and the infrared emission receiver may be connected with the power and control unit.

Preferably, lever locking means of the actuating mechanism comprise electromagnetic lock.

The trigger creep limiter plate may additionally include control means of back action of the trigger. Availability of control means of back action of the trigger makes it possible to provide a mandatory minimum return of the creep limiter to ready position for new locking when releasing the trigger after the shot and makes useless any attempts to artificially avert return of the limiter to ready position, for example, by gripping it with fingers.

Control means of back action of the trigger may be a projection located on the trigger creep limiter plate across the said recess or a U-shaped clamp hingedly installed on the trigger stopper, wherein cavities are provided in the trigger creep limiter plate to carry U-shaped clamp crosspiece, and U-shaped clamp has the stopper for interaction with the trigger bow.

The said problem is also solved in the locking/unlocking system for the firearm trigger consisting of the actuating mechanism configured for mounting on firearms and comprising the trigger creep limiter, control and power unit connected with the actuating mechanism by means of electric wires, and locking means for the trigger creep limiter.

The actuating mechanism according to the invention is configured for mounting on the firearm trigger bow and equipped with electronic gyro and accelerator connected with locking means of the trigger creep limiter, and the trigger creep limiter is designed as a plate configured for sliding along the trigger bow under the trigger, moreover, this plate has a recess for free trigger creep, a stopper for the trigger on one end and a connecting element for connection with the actuating mechanism lever on the other end; and the actuating mechanism comprises locking means of the said lever.

Technical result of such system embodiment is locking of the trigger in case the firearm is pointed towards the floor of ceiling, as well as in case of sudden change of firearm direction.

Preferably, lever locking means of the actuating mechanism comprise electromagnetic lock.

The trigger creep limiter plate may additionally include control means of back action of the trigger.

SUBSTITUTE SHEETS (RULE 26) Control means of back action of the trigger may be a projection located on the trigger creep limiter plate across the said recess or a U-shaped clamp hingedly installed on the trigger stopper, wherein cavities are provided in the trigger creep limiter plate to carry U-shaped clamp crosspiece, and U-shaped clamp has the stopper for interaction with the trigger bow.

As shown in Fig. 1, the remote locking/unlocking system for firearm trigger 1 consists of actuating mechanism 3 mounted on trigger bow 2 of firearm, for example, handgun, power and control unit 4 and wireless communication means between actuating mechanism 3 and power and control unit 4.

Actuating mechanism 3 may be mounted not only on the handgun trigger bow, as shown in Fig. 1, but also on any type of weapon having under-barrel and upper Picatinny rail or other mounting device for auxiliary equipment.

Actuating mechanism 3 is connected with power and control unit 4 by means of wires 5 and comprises creep limiter 6 of trigger 7 and locking means of actuating mechanism 3 lever 8. Lever 8 locking means are designed as an electromagnetic lock comprising electromagnet 9 and latching mechanism 10 of ferromagnetic material capable of taking two positions, in one of which it locks lever 8 motion, for example, by matching teeth of latching mechanism with corresponding hollows in lever 8, and in the second one it releases lever 8. Lever 8 is connected

SUBSTITUTE SHEETS (RULE 26) with creep limiter 6 designed as the plate installed to slide along trigger bow 2 under trigger 7. As shown in Figs. 2 and 3, the plate has recess 11 for free creep of the trigger, stopper 12 for the trigger on one end and connecting element 13 for connection with lever 9 of actuating mechanism on the other. Creep limiter 6 shall be able to move freely along the trigger bow for such a distance so that operation of the trigger is not limited until lever 8 locking means of actuating mechanism 3 are actuated. To prevent attempts to avert return of the limiter in ready position, for example, by gripping it with fingers, the creep limiter may be additionally equipped with control means of the trigger back action represented by projection 14 (Fig. 4) located on the plate of creep limiter 6 across recess 11 or U-shaped clamp 15 (Fig. 5) hingedly installed on stopper 12 of the trigger. If control means of the trigger back action are designed as projection 14, then the height of the rejection shall be such as trigger 7 when pulled at end position of creep limiter 6 towards shooting may freely move above projection 14, as shown on Fig. 9, and if creep limiter 6 is in another end position, when its end bearing stopper 12 raises partially as a result of sliding along trigger bow 2, trigger 7 rests against this projection 14 when returning into initial position, as shown in Fig. 10. If the control means of the trigger back action are designed as U-shaped clamp 15 (Fig. 5), then creep limiter plate shall include cavities to carry U-shaped clamp crosspiece 16 and U-shaped clamp shall have stopper 17 for interaction with bow 2 of firearm trigger. In this case, trigger 7 when pulled at end position of creep limiter 6 towards shooting freely moves above crosspiece 16, substantially aflush with the creep limiter plate surface, as shown in Fig. 11, and if the limiter is in another end position as a result of interaction of creep limiter 6 and stopper 17 with trigger bow 2, U-shaped clamp turns so that trigger 7 rests against crosspiece 16 when returning into initial position, as shown in Fig. 12.

Wireless communication means are represented by infrared emission transmitter 14 and infrared emission receiver 15. As an example, figures show that infrared emission transmitter 14 is connected with power and control unit 4, and infrared emission receiver 15 is installed in actuating mechanism 3 and is of directional type. But in other cases the infrared emission transmitter may be located in actuating mechanism 3 and be of directional type, and infrared emission receiver may be connected with the power and control unit.

Furthermore, actuating mechanism 3 may be equipped with electronic gyro and accelerator (not shown) connected with locking means of the trigger creep limiter. This allows excluding the possibility of shooting in ceiling or floor or shooting in case of sharp turn of the firearm.

Operation of the remote locking/unlocking system for the firearm trigger is as follows.

Infrared emission transmitter 14 (or receiver, if transmitter in installed in the actuating mechanism) is mounted in any point suitable for provision of safety shooting area. When the

SUBSTITUTE SHEETS (RULE 26) firearm is within safety shooting area and pointed towards safe direction, infrared emission receiver 15 continuously receives signal from transmitter 14. At the same time, electromagnet 9 is under voltage and latching mechanism 10 is drawn to the electromagnet allowing free movement of lever 8 and, therefore, creep limiter 6, as shown in Fig. 6. In this case, trigger 7 may be put into shooting position shown in Fig. 6-12 with x-x line.

When leaving the area of stable signal reception from infrared emission transmitter 14, as shown in Fig. 8, electromagnet 9 is instantly de-energized resulting in lowering of latching mechanism 10 and, therefore, blocking mobility of creep limiter 6 of the firearm trigger, such that trigger 7 cannot be led to x-x shooting position.

The system having control means of back action of the trigger in creep limiter 6 is operated in the same manner. The only difference is that in case of intentional holding of creep limiter 6 or lever 8 to make next shot in prohibited direction trigger 7 will not be able to return in ready position for shooting due to resting against projection 14 (Fig. 10) or crosspiece 16 (Fig. 12).

Thus, the system according to the invention ensures protection against unauthorized shooting of firearms without participation of operator not requiring manufacturing of purpose- designed weapon or any remaking of the existing weapon systems for it.
