Abstract

The present invention changes the length of a gun stock according to a shooter's height and adjusts the distance between the butt of a gun stock and the front sight on the barrel. Recoil caused by firing is not directly absorbed by a shooter's shoulder and is indirectly dispersed then absorbed by the entire shoulder. Therefore, a shooter can take a stable and comfortable shooting stance braced by his shoulder.

Description

Attached firearms and how to assemble them

The present invention adjusts the distance between the butt of the butt and the scale of the barrel by varying the length of the butt for each shooter's height, and the reaction force generated during shooting is not directly absorbed by the shooter's shoulder, but is indirectly dispersed in the shoulder. The present invention relates to a cannon-fired firearm and a method of assembling the same, which is absorbed in a whole to allow a fire to be fired in a most comfortable and stable fire position.

For example, the supply of military or police supplies, clothing, boots, gloves, underwear, bulletproof hair, etc. are produced and distributed according to the body size, and the specifications of all objects and facilities are changed to meet the changing body size and body shape in society. Nevertheless, firearms are manufactured and paid for the same size, and there is irrationality that all troops fire and evaluate the same regardless of the size of the kidney. Therefore, the firearms pass rate of the gun and the appropriate troops of the gun, which has been given the body standard is high, but the short- and long-term soldiers have low pass rate. It has been judged as an individual shooting ability so far, and there has been a disadvantage that is undervalued. Therefore, the firearms themselves must solve these problems by distributing them by standard rather than identical products.

In some special missions, rail-controlled firearms are supplied, but this is only necessary for snipers and special missionaries. These guns increase the weight of the firearm, the cost of firearms is high, and natural conditions (dust, sand, water, climate, etc.). Can cause numerous malfunctions, and even if the defense budget is secured and expensive rail-controlled firearms are supplied to the entire military, a certain amount of production and annual distribution is expected.

Production and supply firearms (K-1A, K-2 in Korea) cannot be replaced in batches, and even if rail-controlled firearms are supplied, the replaced equipment will be supplied to some soldiers. Even if replacement equipment is available to some soldiers, height-specific specifications may be necessary for some soldiers and contribute to increased combat power.

The idea is to increase the cost and efficiency of the firearms already in use, and the fact that the distance and accuracy of the scales and scales is directly proportional to the fact that the firearm itself is impossible to modify, and the shoulder restraints (rail butts) In addition, the effect of the rail adapter system developed by the US Army can be obtained by the customized butt improvement, and the increase of the malfunction and the gun weight, which are problems of the rail adapter system, can be achieved. The problem of uninstallation is expected to be solved. In addition, it was judged that it was applicable to all fixed firearms used by the military and civilian.

As a result of examining the difference between the eye and the adhesive point proportional to the height and the change in the hit rate according to the height standard of 5cm, the difference in the hit rate and the pass rate according to the height was confirmed. Necessity abounded.

end. Background and motivation for improvement

1) Background

A) The supplied rifle has the same size of gun, shoulder rest and butt.

B) Firearms developed and distributed in the early 80s have been used by the majority of soldiers to date, regardless of height differences.

C) Rail-type distance-controlled equipment is available for special purposes or sniper use. However, if it is paid to the majority of soldiers due to the high weight of the gun and the cost of the firearm, the enormous budget is expected. This calls for the need for firearms that are differentiated with low-cost equipment based on height-to-height attachment distance (see 6. Comparison of other custom and rail adjustable butts).

D) Rail type butt board is not suitable for natural condition (sand, dust, water, climate, etc.) compared to high price and can cause many functional failures due to numerous conditional changes, resulting in excessive maintenance and loss of combat power. This is expected.

2) Motivation

A) All shots are polished with the same size firearm regardless of the size of the kidney.

B) Short shooters shoot long necks and tall shoots with a shrugged posture, while shooters that are suitable for current guns and physical conditions have a stable and comfortable posture that increases the rate of hit and adapts rapidly. The shooter takes a long time to adjust the firearm, so we think that a tailor-made butt is required.

C) In the manufacture of firearms, the headboard and shoulder rests that meet the body's specifications are manufactured and distributed to maximize individual shooting ability, improve hit rate and inspire confidence, thereby contributing to combat power, and alienation of soldiers due to low shooting performance and low confidence. It can contribute to the development of combat power by eliminating worries about sexual performances, preventing accidents, and inducing high passing rate for low bullets.

I. Primary direction of improvement

1) The shooter should shoot in the most comfortable and stable stance and help improve the hit rate and rate of passing the shot.

2) Firearms suitable for the most comfortable and stable posture will be distributed to individuals so that they can have confidence in shooting and confidence in firearms.

3) It is excluded that the weight of the firearm is in violation of the weight reduction of the equipment intended for use.

4) The supply cost of firearms should be maintained at the same level as current firearms.

5) Do not spend a lot of budget on the modification of equipment.

6) It must be applicable to all fixed firearms used at home and abroad.

Accordingly, without modifying the gun itself, the repair parts, butts and shoulder rests are combined with fixed production-adjusted parts according to several specifications to provide appropriate firearms according to the height standard.

7) Differentiated production demands according to height specification distribution

-Supply of repair parts at a proportion according to them (see Table 2, Table 3, Table 4, Table 5)

8) Initially supply the necessary amount according to the height standard when manufacturing the firearm, and then adjust the production amount according to the enlisted troops according to the standard and annual.

Yearly Enlisted Soldiers' Standard Height Continues to Rise Annually

170 ~ 174cm before 2000 175 ~ 179cm as of 2008

9) The firearms produced and distributed above will solve all problems related to shooting, such as shooting in a stable position, improving shooting efficiency, increasing confidence in firearms, increasing combat power, reducing budgets, raising confidence and increasing accident prevention effects. Expected to.

2. Current Status and Problems

end. Current situation

1) Unreasonableness of individual evaluation of the use of equipment of the same standard (Refer to Table 4 Fire Pass Rate by Height, Table 5 Fire Pass Rate by Eye and Adhesion Point)

2) Shooting with individual discomfort index disregarded by using the same standard equipment, problems of the same evaluation.

I. problem

1) Find problems with the same standard firearms

A) The distance between the scale, the scale, and the eyes (5cm) is the same for all shooters.

B) find the difference between the eye and the point of attachment

○ The difference between the eye and the point of adhesion depends on the size of the kidney.

○ The difference between the eye and the adhesive point is equal to 60% or more for each 10mm average.

※ Refer to Table 1, Eye and Adhesion Distance Analysis Results

2) Adaptation and inadequate bilateralization of kidney and equipment by the use of the same equipment

A) Suitable person: Shoot under stable conditions in suitable condition of height and equipment

B) Ineligible persons: Shoot under unstable conditions with unsuitable heights of the kidneys and equipment;

3) Unreasonability determined by 100% individual shooting ability when shooting accuracy decreases

4) Those who fail are always inherent in factors that cause safety accidents due to poor shooting results, self-restraint pressure factors and psychological anxiety.

Table 1

On the other hand, it describes the K1A rifle used in the Republic of Korea military, one of the conventional firearms firearms according to the prior art.

The K1A rifle was developed based on the K2 rifle designed for the Korean body type. The difference is that the K2 rifle has a collapsible butt plate, whereas the K1A rifle can adjust the length by pushing and pulling the butt in a rail type. It is designed for special forces and is used as the main weapon of special forces such as special forces and police commandos.

Referring to this in more detail with reference to the accompanying drawings, the K1A rifle is a butt, that is, the shoulder rest is adjustable length on the rear side of the main body 1 having a muzzle 1A as shown in FIG. (2) is provided, the shoulder support (2) is an elliptical ring connected to the end of the pair of guide rails (21) (21A) parallel to each other in the horizontal direction as shown in Figs. The support part 22 formed in the form is integrally formed in the vertical lower side direction.

In addition, the support 23 of the rubber material is wrapped around the outside of the support 22 by insert injection, and the uneven portion 232 is formed on the adhesive surface 231 of the support 23 in contact with the shoulder. The upper end of the adherent surface 231 is configured to protrude toward the upper side of the guide rails 21 and 21A to form the reinforcement protrusion 233.

In addition, the guide rails 21 and 21A are formed with a closed groove 211, a first stage open groove 212, and a two stage open groove 213 so that the

On the other hand, when shooting, you can see that the gun is lifted up after firing. This phenomenon is caused by a force couple, which is the force that retracts the gun when it fires, that is, the reaction force When absorbed by the shoulder, it refers to the rotation moment generated when the vertical distance between the axis where the reaction force is transmitted and the shoulder contact point supporting the butt plate is different.

Even in the case of the conventional K1A rifle, the supporting part 23 including the support part 22 is biased to the lower side with respect to the guide rails 21 and 21A to which the reaction force is transmitted. This occurs, wherein the reinforcement protrusion 233 formed on the upper end of the support 23 resists the right force, but the material of the reinforcement protrusion 233 is made of rubber, and the reaction force is directly transmitted to the support 23. Still, there was a problem in which gun elevation caused by the right force was large.

In addition, even if the concave-convex portion 232 is formed on the adhesive surface 231 of the supporting portion 23, the frictional resistance against the right force is small, it is possible to prevent the shoulder restrained from slipping off the shoulder by the right during shooting. There was no problem.

The present invention has been made to solve the above-described problems, by providing a customized gun that is most suitable for the height and eye and shoulder length, the shooter can have confidence in participating in shooting training in a comfortable and stable posture and improve the gun The purpose of the present invention is to provide an attached firearm and a method of assembling the same, which contribute to improving the shooting efficiency at low cost and high efficiency.

In addition, the present invention allows the reaction force generated when shooting can be absorbed in the entire shoulder indirectly dispersed state, not directly absorbed by the shoulder through the guide rail and the support portion, by the reaction force absorbed indirectly by the shoulder The purpose is to be able to resist stronger forces.

This can prevent the gun from shaking.

In addition, the ring body 31 includes an arc-shaped curved portion 32 to be in close contact along the shoulder line when the shoulder, and the inner space so that the flesh portion of the shoulder can be inserted into the inner space of the ring body 31 To form the insertion groove (33). At this time, the curved portion 32 is formed along a circle having a diameter (D) of 35 to 40 π as shown in FIG. 5, wherein the 35 to 40 π form a circle that can be in close contact with the shoulder line most closely. It's in shape.

In addition, the ring body 31 is formed of a metal material in order to increase the drag resistance by the drag bar (31A), in which case a high-strength crimped plastic material is used.

In addition, the outside of the support 22 and the reinforcing member 3 is coated with rubber to form a coating film 4, the coating film 4 of the support 22 and the reinforcing member 3 opened before and after Configured to close the front portion.

In the present invention configured as described above, when the gun is attached to the gun, the reinforcing member 3 of the shoulder rest 2 formed in an arc shape along the shoulder line by the curved portion 32 is in contact with the shoulder, and the reinforcing member ( The flesh portion of the shoulder is inserted into the insertion groove portion 33 formed as the inner space of 3). At this time, the shoulder contact portion is made from the upper reinforcing bar (31A) of the guide rails (21) (21A) to the lower end of the support portion 22 is made over the entire reinforcement member (3).

When fired in such a state, the reaction force is transmitted to the support part 22 via the guide rails 21 and 21A, and the reaction force transmitted to the support part 22 is the force preventing jaw of the support part 22 and the reinforcing member 3. It is formed between the 31A and is not transmitted directly to the reinforcing member 3 by the gap (G) cut off between them, the path is moved to the lower side of the support portion 22 and indirectly transmitted to the reinforcing member 3. Absorbed by the shoulders.

As the reaction path of the reaction force is indirectly made, the impact force applied to the shoulder by the reaction force can be dispersed to reduce the force, and the bias of the reinforcement member 3 of the reinforcing member 3 formed of the metal material against the reduced force ( The large resistance of 31A) can significantly reduce the shooting phenomena caused by the shooting force.

In addition, since the flesh portion of the shoulder is inserted into the insertion groove portion 33 formed as the inner space of the reinforcing member 3, the frictional resistance to the right force is increased, it is possible to more effectively prevent the departure of the shoulder restraint by the right force.

As described above, although described with reference to a preferred embodiment of the present invention, the present invention can be variously modified or modified without departing from the spirit and scope of the present invention described in the claims Those skilled in the art will appreciate.

As is apparent from the above description, the present invention has the following effects.

1) Improving individual shooting ability and rationality of evaluation by distributing customized firearms.

3) Shooting and evaluating all soldiers under the same conditions by distributing equipment that is perfectly harmonized according to height and distance between eyes and attachment point.

6) Freedom from psychological self-denial and pressure of disqualified persons.

7) Expect low cost, high efficiency shooting culture.

9) 1st round of candidates expected to increase;

10) It can be applied to all handguns used at home and abroad.

11) Increases combat power by improving the passing rate of all soldiers

12) Securing time for combat training in other fields by improving the adaptation speed to firearms

13) 1st successful candidate rise and 15% increase in accuracy rate expected

14) Significantly reduce the shooting phenomena caused by the shooting force and improve the shooting accuracy

15) During shoulder attachment, the shoulder part of the shoulder is inserted into the insertion groove formed as the inner space of the reinforcing member, so as to obtain a large frictional resistance against the right hand force and to prevent the departure of the shoulder restraint.

The present invention is applicable to all hard gun firearms used by military and civilian at home and abroad, can be used by each height in each country including the Republic of Korea, and when exporting the gun, can be selectively exported by country, race, Other applications include survival game firearms and shotguns.
