Definitions

• This patent refers to an electronic lock system of the firearms trigger, which will be triggered by radio frequency.
• the competent authorities may, at a distance and safely, block the use of the weapon by users who are in a given circumstance, putting in risk one or more innocent people, or any circumstance that makes necessary the lock, according to the criteria established by these authorities. It permits, therefore greater control of bad use or indiscriminate use of these weapons.
• Percussion lock system integrated to mechanism of firing semi-automatic pistol (patent no. IP 9402252-6 A), screw-lock; lock the stock sheet; screw that locks the trigger; apparatus to compel the trigger lever and hook the latch in a machine pistol (patent no. 9305705-9 A).
• AU these systems are mechanical, be in the weapon and have no key to effective locking against unauthorized use. Therefore, anyone who has knowledge about its use can disable these mechanisms and quickly put the weapon ready to shoot.
• the system of electronic trigger lock composed of an electronic microcontroller coupled with a transceiver, which will emit radio signal, so that it can be located and can receive a signal of teams of police equipment or expertise.
• the transceiver Upon receiving the signal, the transceiver sends the message to the microcontroller, which resend for linear microdrive, which will move the pin into the trigger and lock, preventing the user to make shots and achieve innocent people.
• the lock system consists of a microcontroller that process the information received by the transceiver.
• the set will be fixed on the stock sheet, the grip of weapon and should be fine enough to not difficult its correct handling.
• the public authority may have a more effective control of the use of firearms by persons in its service.
• military police could use their weapons normally, but when stolen or lost, the people responsible will be contacted for locking the trigger and still could track the location of them.
• the system can be placed in almost all the firearms that have trigger and cable that can be hold by one hand, such as rifles, machine guns, manual and automatic rifles, carbines, pneumatic weapons of pre-compressed air, revolvers and pistols automatic and semi-automatic.
• the components of the electronic device will be electrically powered by a battery plate inserted in the stock sheet, opposite the plate, where they find the handle of the device. This battery will be the largest size possible, next to the size of the stock sheet, similar to those used in cell phones, which provide a battery with more storage.
• FIGURE 1 represents a partial view of the side of a conventional firearm, which shows primarily the grip and location of invention devices.
• a schematic drawing was used as a example of a semi-automatic pistol, as a weapon widely used today and have all the necessary requirements for a better understanding.
• the FIGURE 2 is a three-dimensional design of the trigger of semi- automatic pistols, with location of the hole which the pin will go.
• the invention was based on this type of trigger, but it may suffer small modifications to be used in other types, such as those in the shape of a hook, without, however, distort the system so relevant.

• the grip (9) which is frame (8), which is the main block, made of steel or synthetic polymers, which gives way to the weapon.
• the board of stock sheet (10) is attached to the grip (9) by the screw (12) and screw (13).
• the stock sheet (11) is attached to the grip (9) by the screw (14) and screw (15). Almost all components of the system in question are within the board of stock sheet (10), which has thick enough to hold them, because all the components are very thin. It is emphasized that the system does not interfere in the other devices of the weapon and not in the way it is used.
• the user's fingers involve the basement below the grip (9), which is the average, the ring and the minimum.
• the indicator is used to press the trigger and thumb gives strength to involve the top of the basement grip (9).
• the middle or ring finger By involving the grip (9), the middle or ring finger will press the small button of pressure (1) that will turn on the system.
• the microcontroller (3) examine whether the trigger is blocked by pin (5) and if there is any order received by the transceiver - transmitter / receiver (2) to lock the trigger (6).
• a software is necessary to receive and process the signals received. This type of software accompanying the microcontroller and all is found in the market.
• the software being used should manage its database to create and modify different types of users with variation for permission to use and also of administrators. It should create more than eight-digit passwords for users, in addition to protecting the confidentiality of information through programs of high-level encryption.
• the communication between the software of linear microcontroller (4) and the authorized administrator, or even with user of the firearm, can be made through the transceiver - transmitter / receiver (2) or by USB port (20), to connect to a computer. If the trigger (6) is locked by pin (5) and has no record of any order to lock, immediately the microcontroller (3) send a signal to the linear microdrive (4) to move the pin (5) in order out the frame (8) of the firearm. The pin (5) across the frame (8) and the plate of stock sheet (10) and will be withdrawn from the basement which is inserted inside the hole (7) of the trigger (6) when the system is off. When you move, commanded by linear microdrive (4), it will move out of the hole (7), which frees up the trigger (6). To release it, also release all existing systems in weapon. The person authorized, pressing the trigger, can make as many shots as desired.
• the microcontroller (3) when connect the system, already exists an order, received by the transceiver (2), to block the trigger (6) of the firearm, the microcontroller (3) not send the signal to the linear microdrive (4). Therefore, the pin (5) remains inside the hole (7) of the trigger (6), which blocks its movement and not allow shots.
• the microcontroller (3) could send a contrary signal, so the linear microdrive (4) put the pin (5) into the hole (7) of trigger (6).
• the pin (5) would be stronger, which would prevent even more, any movement of the trigger (6).
• the microcontroller (3) check this condition and send a signal to linear microdrive (4) to move the pin (5) in order into the weapon. This cross the frame (8) and the plate of stock sheet (10) and insert a hold within its hole (7) of the trigger (6). When you move, commanded by linear microdrive (4), it will go into the hole (7), which locks the trigger (6).
• the linear microdrive (4) is offered on the market in various shapes and sizes, which facilitate their use in the system. It requires space, part of the plate stock sheet (10) and in part of frame (8). Nevertheless, not interfere in the handling of the weapon to be at the top, next to the trigger (6) and slightly above the magazine catch (16).
• the linear microdrive (4) should be well set in the frame (8), if possible fastened or incorporated into this, to prevent its forced, withdrawal together with the pin (5), which would cause discharge of the trigger (6).
• the trigger (6) is initially locked when the system is off, which avoids violation of the system by the user, such as damage the electronics or off the system with the withdrawal of the battery (18). We must be avoided, in every way, the release of the trigger (6) and use the weapon for shooting before verification, by the system, if there is a command to lock has been sent remotely.
• the system will be electrically powered by a battery (18) plate inserted in the stock sheet (11) opposite the plate stock sheet (10), which contains the other system components. Thus, it may have a sufficient size to be fed by a long period, it is seen that the system will shut down most of the time, it is turned on only when the weapon is in hand and with the pressure mini button (1) pressed by finger.

• There are several types of batteries in the market can be designed in accordance with the size and thickness of the stock sheet (11), and can be recharged or exchanged.
• the connection wire (19) between the battery and other components of the system can pass in the back of the grip (9), behind frame (8) or inside.
• the battery which will be rechargeable, may be constantly connected to the power.
• the risk of needing the weapon and it is discharged is very low.
• the system will not work and the weapon will remain locked.
• transceiver - transmitter / receiver (2) The electronic system of locking the trigger of firearms is driven via radio frequency by an integrated circuit of radio called transceiver - transmitter / receiver (2).
• This type of circuit radio is already used commercially and already there are those that support both 2G networks TDMA / AMPS / GSM, as platforms for data of 2.5G GPRS / EDGE at high speed.
• This technology becomes very useful because it can be given the remote to lock the trigger (6) through devices that send signals protected, created specifically for the control by responsible teams, from GSM mobile phones or TDMA, or even cell phone networks using overlapping GAIT, which add the capacity GSM and data services to the mobile Internet infrastructure wireless TDMA / AMPS existent.
• the Internet can also be used, or via mobile phones (GPRS), or by wireless networks (“wifi”), since the transceiver (2) sends and receives radio frequency signals, and both the cellular network as wireless already use this technology, is quite widespread and competitive price, which facilitates its use on a large scale.

• Wifi wireless networks
• Bluetooth is being increasingly used in various electronic equipment such as cell phones and their accessories, appliances, sound and image, and also in various appliances. It is actually a cheaper technology, equipment were low and spend little energy. However, its sphere of action is still very restricted, which is around 10 meters. Some reach 100 meters, but at the moment are more expensive, bigger and spend more energy.
• the trigger via satellite can also be used and cover a much larger area of control, but the technology is currently more expensive.
• these technologies are being widely used and refined at intervals of time increasingly short in a few years, if not months, you can compete with the drive radio frequency in price, size and sphere of action.
• the ideal would incorporate the three systems - radio frequency via "Bluetooth" and satellite, so that gives total control and ability to quickly lock, regardless of where the firearm is.
