BOLT BRAKING SYSTEM IN FIREARMS

Abstract

The invention relates to the restructuring of the recolt guide (2) in order to prevent the firing line from deteriorating by reducing the impact force of the bolt (7), with the recolt spring (5) that is compressed during firing and moves back together with the bolt (7) returning to its original position, while minimizing the damage to the elements that make up the pistol.

[0038] The brake mechanism of the bolt (7), which is the subject of the invention and exploded view of which is shown in FIG. 3, is related to the configuration of the recolt guide (2), on which the recolt spring (5) passes and thus guides the back and forth movement of the gun mechanism.

[0039] The structuring of the recolt guide (2), which is the subject of the invention and the detail of which is given in FIG. 5, consists of stages with at least two diameters. It is formed by bringing the a set screw (1), which is positioned by passing from the barrel (9) to the small diameter stage (10.1) of the recolt guide (2), a set screw head (1.1) positioned per set screw (1), a spring (3) resting on the step limit and resting on the large diameter step (10.2) of said recolt guide (2), a nut (4), which is prevented from turning in the recolt guide (2) by placing a nut screw (4.1) in the screw hole on it and into which the tip of the set screw (1) is inserted, and a bottom screw (6) that closes the recolt guide (2) just behind the said nut (4) and prevents the recolt spring (5) from jumping back over the guide and coming off. (FIG. 2)

[0040] By means of the arrangement of the recolt guide (2) that is the subject of the invention, it is aimed to protect the firing line, not to damage the mechanism, and to provide ease of use to the user by reducing the intensity of the force that occurs when the recolt spring (5) is compressed after firing and returns together with the bolt (7).

[0041] The inner part of the recolt guide (2) is carved in different diameters and formed as at least two different levels. A set screw (1) is inserted through the small diameter step (10.1). A spring (3) is placed on the part of the set screw (1) that passes through the small diameter step (10.1) and extends to the large diameter step (10.2). Said spring (3) passes into the body of the set screw (1) and abuts to the wall (limit) of the smaller diameter step (10.1) by sitting on the larger diameter step (10.2) of the said recolt guide (2).

[0042] The tip of the set screw (1) that passes through the spring (2) is connected to a nut (4) that sits inside the large diameter step (10.2). There is at least one nut screw (4.1) hole on the nut (4). A nut screw (4.1) is connected to this hole by passing through the channel (2.3) opened on the recolt guide (2), thereby allowing the nut (4) to move back and forth within the recolt guide (2), but the rotation of the nut (4) is prevented. By this way, the nut (4) cannot rotate when the set screw (1) connected to the nut (4) is turned, and the nut (4) moves back and forth within the recolt guide (2) by moving on the grooves on the set screw (1).

[0043] The compression degree of the spring (3) located on the set screw (1) and jammed between the nut (4) and the wall of the small-diameter step (10.1) is adjusted by screwing the set screw (1) into the nut (4) in each turn. The more the set screw (1) goes into the nut (4), the more the spring (3) gets compressed. The setting numbers (2.1) on the recolt guide (2) and shown in the values of 1 to 5 show the degree of compression of the spring (3) as the set screw (1) is turned and screwed into the nut (4). The degree of compression of the spring (3) creates a reverse force against the force generated when the bolt (7) comes back and hits the set screw head (1.1). Thereby, the force to be created by the recolt spring (5) while returning rapidly is balanced.

[0044] The bottom screw (6) part, on the other hand, contains a protruding head so that the recolt spring (5) does not come out from the back part of the recolt guide (2), and closes the whole system by passing through the large diameter step of the recolt guide (2) and abutting up to the nut (4) part. Thus, the recolt guide (2) becomes monolithic and a braking system is formed by positioning the recolt spring (5) on the recolt guide (2). As an alternative use, by passing a pin (2.4) through the pin slot (2.5) on the recolt guide (2), said bottom screw (6) is prevented from coming back by placing said pin (2.4) in the bottom screw pin slot (6.1) on the bottom screw (6). (FIG. 7)

[0045] After the recolt guide (2) is fully mounted into the gun, the bolt (7) hits the set screw head (1.1) when the recolt spring (5), which is compressed by going backwards together with the bolt (7), returns to its original position when the shot is fired. When the bolt (7) hits the set screw head (1.1) with the force generated by the recolt spring (5), the N.sub.1 force (5.1) is applied on the set screw (1). This N.sub.1 force (5.1) is transmitted to the nut (4) to which the set screw (1) is connected. Against the movement of the nut (4), the N.sub.2 force (3.1) opposing the tension of the spring (2) compressed between the nut (4) and the wall of the small diameter step (10.1) is applied. Together with this N.sub.2 force (3.1), against the N.sub.1 force (5.1) created by the recolt spring (5) in the forward direction, an N.sub.2 force will form in the spring (3) in the recolt guide (2), by the set screw (1) connected to the nut (4) pulling the said nut (4).

[00001]$N_T=N_1-N_2$$N_T<N_1$

[0046] The total force, namely NT, will be formed by the difference between the larger N.sub.1 force (5.1) of the recolt spring (5) and the reverse smaller N.sub.2 force (3.1) of the spring (3) in the recolt guide (2). The N.sub.2 force (3.1) of the spring (3) in the recolt guide (2) will reduce the N.sub.1 force (5.1), thus reducing the impact force. By this way, depending on the use of the mechanism, it will be ensured that less damage will be taken, and the user will be comfortable. (FIG. 1)

[0047] Each time the bolt (7) moves back, a force is applied to the set screw head (1.1) of the set screw (1) screwed into the nut (4) with the larger stepped diameter (10.2) of the recolt guide (2) passing through the small stepped diameter (10.1) of the recolt guide (2). As a result of this force exerted by the bolt (7), due to the possibility of the threaded tip of the adjusting screw (1) to open, a screw (8) is passed through the screw slot (2.2) located on the recolt guide (2) and positioned on the screw path (1.2) on the set screw (1). (FIG. 6) Thus, as a result of the force applied by the bolt (7), the recolt screw (1) will not be able to move and the compression degree of the spring (3) will not be changed. In addition, said screw path (1.2) provides a movement area for the screw (8) located on the said screw path (1.2), while the set screw head (1.1) is rotated and the set screw (1) is connected to the nut (4). (FIG. 4)

[0048] The compression force of the spring (3) in the recolt guide (2) can be set to a value between 1 and 5 by means of the set screw (1). By this way, the value of the reverse force that the spring (3) will apply to the recolt spring (5) can be determined according to the usage. (FIG. 5)
