TECHNICAL FIELD The present invention relates to a trigger assembly of a firearm, and more particularly to a trigger assembly configured so that only the owner of the firearm can pull the trigger.

Firearms, such as pistols, rifles, and air guns, are killer weapons, which can be used for crimes if a police officer or soldier carrying a firearm is lost or robbed by another person, especially a lost gun. If used by someone unfamiliar with handling firearms, there is a high risk of accidental accidents.

That is, a serious problem of death or injury occurs when an inexperienced person who is not authorized to fire a gun fires a trigger or fires a shot due to a malfunction of the trigger.

Therefore, it is required to mount the trigger assembly 1 to the gun body 1, which has a structure that can limit the operation of the trigger so that no one other than the gun owner is allowed to operate the gun's trigger.

It is an object of the present invention to provide a trigger assembly for a firearm having a structure capable of limiting the operation of the trigger so as not to be triggered when it is determined that the firearm owner is not allowed to fire a bullet. .

Still another object of the present invention is for a gun that can prevent a bullet from being fired due to an unexpected malfunction of the trigger by an unintentional external force without the gun owner intending to fire, i.e. without forcing the index finger to the trigger. It is to provide a trigger assembly.

The trigger assembly for a gun according to the present invention for implementing the above object is installed in a predetermined area of the gun body, the trigger for rotating the hammer and the ball by rotating by the index finger of the gun; And a trigger actuation control unit disposed in an area adjacent to the trigger in an area of the gun body to control actuation of the trigger.

And a stopper member 50 fixed to 40 and having one end exposed to the exterior of the housing 60.

The position and configuration of each member constituting the trigger operation control unit will be described in detail with reference to the drawings.

housing (60)

The housing 60 is fixed to the side of the gun body 1, and a predetermined space is formed therein.

Driver 10 and power supply 20

The driving unit 10 is fixedly disposed in the internal space of the housing 60, and the power supply unit 20 for supplying power to the driving unit 10 is also disposed in the housing 60. On the other hand, although not clearly shown in the drawings, the gear portion extending in the axial direction is formed on the outer peripheral surface of the drive shaft 11 of the drive unit 10.

Guide Rod 30 and Moving Member 40

The guide rod 30 is fixed to the side member of the housing 60 and is preferably positioned perpendicular to the side member. The moving member 40 is a disk-shaped member in which the guide rod 30 is fitted in the center part. In addition, a toothed portion is formed on an outer circumferential surface of a portion of the moving member 40, and the toothed portion maintains a state in which the toothed portion and the helical tooth are coupled to the toothed portion formed on the outer circumferential surface of the drive shaft 11 of the driving unit 10.

By this structure, when the drive shaft 11 of the drive unit 10 rotates, the moving member 40 is linearly moved along the guide rod 30 while the rotation is suppressed by the guide rod 30.

On the other hand, it is preferable that the thickness of the area | region in which the tooth of the moving member 40 was formed is the same as the movement distance of the stopper 52 mentioned later, or it is thicker than the movement distance of the stopper 52.

Stopper Member 50

The stopper member 50 disposed in the housing 60 is integrated with the main body 51 and the main body 51 fixed to one side of the moving member 40, and one end thereof is exposed to the outside through the side wall member of the housing 60. Included stopper 52. As shown in FIG. 1, the stopper 52 exposed out of the housing 60 is located in a space formed between the rear of the trigger 2, the trigger 3 and the gun body 1.

On the other hand, although not shown in the figure, the trigger operation control unit is further connected to the RF signal transmission / reception module and the RF signal transmission / reception module disposed in the housing 60 and further comprises a controller for controlling the driving of the drive unit 10. Include.

In order to use a gun equipped with a trigger assembly according to the present invention (i.e., fire a shot), the gun holder must carry a tag that generates an RF signal. For example, the tag generating the RF signal is preferably in the form of a ring that is fitted to the finger of the gun holder in contact with the trigger 2 for shooting.

The function of the trigger operation control unit composed of the above members will be described in detail with reference to the drawings.

The initial state of the trigger operation control unit is a state where one end of the stopper 52 of the stopper member 50 disposed in the housing 60 is exposed to the outside through the side wall member of the housing 60. In this state, the stopper 52 is located in the space formed between the rear of the trigger 2, the trigger 3 and the gun body 1, as shown in FIG.

Thus, even if a person other than the unauthorized gun owner (ie, the person carrying the RF signal generating tag) carries the gun, the trigger 2 does not move backward by the stopper 52, so that no bullet is fired.

When the gun owner, who is authorized to use the gun, shoots the index finger with the RF signal generating tag in contact with the trigger 2, the RF signal generated in the RF signal generating tag is transmitted to the controller mounted in the trigger operation control unit.

The controller compares the transmitted RF signal with the RF signal code stored in the memory. If it is determined that the transmitted RF signal and the RF signal code stored in the memory are the same, the controller operates the driving unit 10.

The driving unit 10 is operated by the power supplied from the power supply unit 20, and the moving member 40 in helical contact with the driving shaft 11 rotating in the first direction has the guide rod 30 inside the housing 60. Move towards. The stopper member 50 fixed to the movable member 40 by the movement of the movable member 40 is also moved toward the inside of the housing 60, and consequently exposed to the outside of the housing 60, that is, of the trigger 2. The stopper 52 located in the space between the rear, the trigger 3 and the gun body 1 enters into the housing 60.

The bullet gun can be fired by the gun owner pulling the trigger 2 in a state where the stopper 52 which suppresses the movement of the trigger 2 enters the inside of the housing 60.

At the same time, the controller transmits the RF signal through the RF transmit / receive module as a prescribed signal, and the transmitted RF signal is transmitted to the RF transmit / receive module connected to the situation room. Commanders and supervisors, such as the situation room, can therefore know that the firearm is ready to fire by an authorized user.

If the gun holder is moved away from the firearm by the end of shooting or the end of gun use situation, ie the RF tag is away from the gun trigger assembly, the RF transmit / receive module does not receive the RF signal. Under these conditions, the controller operates the drive unit 10 to rotate the drive shaft 11 in a second direction opposite to the first direction, thereby exposing the stopper 52 to the outside of the housing 60 to expose the rear surface of the trigger 2, Placed in the space between the trigger 3 and the gun body 1 (state of FIG. 1). Accordingly, even if an unauthorized person other than the user of the firearm possesses the firearm, the trigger 2 does not operate due to the stopper 52 located behind the trigger 2, and thus the fire is not possible.

On the other hand, when the operation of the trigger 2 should be maintained for a long time, such as in an emergency, that is, when the stopper 52 should be located inside the housing 60, the stopper 52 due to the RF signal transmission from the RF tag. ), The movement of the stopper 52 can be suppressed through a switch (not shown) mounted on the housing 60 in a state where the) is in the housing 60.

For example, by mounting a switch in the housing 60 that cuts off the power flowing from the power supply unit 20 to the driving unit 10, the stopper 52 is always located inside the housing 60 so that the gun can always be fired. I can keep it.

Although the present invention has been described with reference to the preferred embodiments, these are merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible.
