Description

Rail for pistol {RAIL FOR PISTOL}

The present invention relates to a rail for a pistol, and more particularly, to a rail for a pistol used by attaching pistol accessories such as a laser sight or flash to a pistol.

In general, military firearms include pistols, rifles, submachine guns, machine guns, and shotguns, and these types of firearms are mainly used by being distributed to soldiers according to the tactical form of operation.

Among these types of firearms, pistols are operated so that units or commanders performing special missions can conveniently carry and use them.

In Korea, under the name K5, it has developed and used its own pistol.

These pistols are equipped with a mechanical sight, such as a sight and a scale, which makes aiming easier when shooting.The method of aiming using a sight and a scale requires periodic training through repeated training, but accuracy is improved. Can be improved.

On the other hand, as firearm accessories such as laser sights are popularized in recent years, a method of using a laser sighting machine by attaching it to a pistol has been adopted.

Since such a laser sight can easily check the aiming point with the naked eye, the aiming speed is faster than that of a mechanical sight, and even a beginner can perform accurate shooting.

In order to use such a laser sight, the pistol must be equipped with a rail system according to the military standard called Picatinny rail, but the pistol has a size slightly larger than that of an adult palm, so it is not easy to attach the rail. It is made into.

In particular, the K5, which has been developed and operated in Korea, is driven to move forward again with the slide moving in the opposite direction of the muzzle every time to reload the bullet while discharging the casing, so it is directly in the upper section of the slide of the gun. It has a structure that makes it difficult to combine the rails.

Accordingly, among the conventional pistol rails, the rail attached to the upper section of the slide of the gun generally wraps around the entire barrel of the pistol, but has a structure that is coupled to the handle. There is a problem of becoming heavier.

Such a problem occurs in the conventional pistol rail that is mounted under the slide of the gun.

Due to the problem of rails mounted on conventional pistols, recently newly developed pistols are manufactured in a state in which rails are machined on a gun body and a slide.

Accordingly, Korean Patent Registration No. 10-1847397 (April 10, 2018), which is Patent Document 1, discloses a lower gun body for a pistol equipped with a removable metal rail, and such Patent Document 1 discloses the gun body itself. By processing the rail shape, the problem of not having to use a very large rail as described above is solved.

However, since the gun body disclosed in Patent Document 1 is applied only to a newly manufactured pistol, there is a problem that cannot be applied to a previously manufactured K5 pistol.

Therefore, in the case of installing a rail on a K5 pistol that has not been processed with a conventional rail, it is possible to extend the area of the rail to the handle for connection of the rail, or to combine the rail even when the rail is not extended to the upper space of the slide. There is a need for technical solutions.

On the other hand, rails that are conventionally coupled to pistols are mostly fixed to the gun body or handle using bolts, and the means for fixing the rails are coupled to the pistol by causing strong pressure to occur in the coupling direction of the bolts. Since the direction of providing the coupling force is provided only in the coupling direction of the bolts, when an impact or the like is transmitted from a direction different from the direction in which the bolts are coupled, the rail is slightly twisted in the pistol.

Therefore, in the case of coupling the rail to the conventional pistol, there is a need for a technical solution that enables the rail to be firmly fastened to the pistol by forming a coupling force in a direction different from the coupling direction of the bolt.

Korean Patent Registration No. 10-1847397 (April 10, 2018 announcement)

In order to solve the above problems, the technical problem of the present invention is to extend the area of the rail to the handle for the combination of the rail, or to extend the rail to the upper space of the slide in the case of installing and operating a rail on a conventional K5 pistol that has not been processed. It is to provide a pistol rail that can be combined with the rail even in the non-extended state.

In addition, another technical problem of the present invention is that when a rail is coupled to a pistol, the rail is strongly pressed in each direction of the pistol and the pistol so that a fastening force is provided in a direction different from the direction in which the bolt is coupled. It is to provide rails for pistols that can be used.

The pistol rail of the present invention for achieving the above technical problem is a pistol rail that is in close contact with the pistol trigger protector and the barrel rest, and one side of the trigger protector in a state in which a partial region of the trigger protector is accommodated. A first coupler including a first guard receiving area in close contact with the; A second guard receiving area that is formed to be in close contact with the other side of the trigger guard while receiving a partial area of the trigger guard, wherein the second guard receiving area faces the first guard receiving area Coupler; A plurality of inserting and fastening portions inserted between the first guard receiving area and the second guarding receiving area, a contacting area extending from the inserting and attaching part to be in close contact with the lower surface of the barrel rest, and a lower area of the contacting area. A rail coupling unit formed in a shape in which the rail grooves are spaced apart from each other, and including a rail region for attaching firearm accessories; And a bolt portion which is screwed through the body of each of the first and second fasteners and the insert and fastening portions. Includes.

In this case, the pistol rail has a chamfered portion of the first guard receiving area and the second guard receiving area, which is in close contact with the insertion fastening part and toward the muzzle direction, thereby further forming a fitting inclined surface, and the inserting fastening part is the coupling. The portion in contact with the old inclined surface is chamfered to further form the inclined surface of the coupling part, the inclined surface of the coupling part is configured with an inclination angle with the trigger guard at a narrower angle than the angle with the inclined surface of the coupling hole, and the bolt part is the first coupling When screwed so that the gap between the sphere, the second coupling member, and the insertion coupling portion is screwed to narrow the gap between the first coupling member and the second coupling member, the coupling portion inclined surface pushes the coupling member inclined surface toward the trigger guard. It is possible to increase the adhesion force pressing the trigger protector on one end surface of the insertion and attachment portion.

In addition, when the pistol rail is screwed so that the bolt portion is screwed to the first coupling member, the second coupling member, and the insertion coupling portion to narrow the gap between the first coupling member and the second coupling member, the In the rail fitting, the contact area is formed such that the contact area is formed to be wider in the direction of the trigger guard in the direction of the trigger guard from the muzzle direction with respect to the central axis of the muzzle, so that the insertion and attachment part can be in close contact with the trigger guard. It is possible to press the lower surface of the barrel rest.

The present invention is a state in which the first and second couplers are strongly pressed against a partial area of the trigger guard so that the insertion and fastening portions of the rail coupler are coupled by bolts between the first and second couplers. Because it is combined with the rail, it is possible to connect the rail to the handle or the total body without extending the rail to the upper space of the slide or to allow the rail to be connected, thereby improving portability by occupying less volume and less weight than the conventional rail. It works.

In addition, in the present invention, when the first coupling member and the second coupling member are coupled to the trigger guard, the rail coupling member is strongly pressed toward the trigger protector, so when the rail coupling member is coupled by the first coupling member and the second coupling member. Since the bolt portion provides a coupling force in a direction other than the screwing direction, there is an effect of providing a solid clamping force so that the rail coupling unit does not shake in the trigger guard.

In addition, in the present invention, when the rail coupling member is screwed together with the first coupling member and the second coupling member by a bolt portion, the rail coupling member is not only strongly urged toward the trigger guard, but also is strongly urged and fixed to the lower surface side of the barrel stand. Therefore, since the bolt portion provides a coupling force in a direction other than the screwing direction, there is an effect of providing a solid tightening force so that the rail coupling member does not shake in the trigger guard.
