TECHNICAL FIELD

The subject of the present invention relates to damping of the recoil force as a result of fixing the trigger group to a support point by seating the trigger group in a slot with a pin in order to prevent the recoil force from being transmitted to the user by raising the tip of the barrel with the effect of recoil force after firing.

The present relates to a mechanism that damps the upward movement independent of the receiver after the recoil force is damped and improving the positioning of a return spring in front of the trigger group in order to return the trigger group to its original position.

PRIOR ART

In the state of the art, the bullet core leaves the barrel with the expansion of the gunpowder and comes out of the barrel in each time guns with magazines are fired. As it comes out of the barrel, the reaction/recoil force in the barrel pushes the front bolt of the gun back. When the front bolt is pushed back, it ejects the empty case, making room for the new bullet. Here, the recoil force that occurs after firing not only ensures the re-establishment of the mechanism, but also creates a recoil movement since it will transmit this force directly to the user's hand gripping the gun. Most of the magazine-fed guns create recoil force by moving back the mechanism attached to the receiver in each shot. Since the mechanism attached to the receiver cannot damp the recoil movement, it transmits this movement to the user together with the receiver. This situation causes time losses such as repositioning and re-adjusting the target in each firing.

In th state of the art, the weight of the pistol is increased in order to reduce the sense of recoil felt by the shooter. This extra weight makes the gun unwieldy and tiring for the shooter to use.

In the state of the art, in the document numbered B2190474A, an assembly of baffles i.e. washers cups, cones, or fins etc is constructed in such a way to catch the residual gases which exit the muzzle of a fire arm on discharge of its cartridge. The energy and momentum of these gases act upon the device converting the pressure energy of the gases into mechanical energy in such away as to brake the recoil normally generated when the weapon discharges its cartridge. Thus, recoil reducers employ the expulsion of these residual gases in the form of a jet from vents cut into the barrel of the weapon, or from a detachable vent fitted to the weapons muzzle. This jet effect causes an equal and opposite reaction to brake muzzle lift and also attenuate a proportion of the rearward thrust on the weapon.

In the state of the art, the document numbered U.S. Pat. No. 4,974,493A mentions an automatic pistol having a bolt mounted reciprocally on a frame. The pistol has a plastic buffering element mounted between the gun bolt and the barrel in order to absorb the impact of the bolt between the slide and the frame. By mounting a shock absorbing means between the slide and the frame, its linearity is increased by reducing the bending and recoil force of the slide. In the document numbered U.S. Pat. No. 4,974,493A, an insert is interposed between the slide and the barrel or the frame by means of an adhesive, depending on the design of the pistol assembly. Said buffer or shock absorbing means can be attached to various guns.

Also, in the state of the art, in the document numbered U.S. Pat. No. 8,539,706B1, the recoil reduction is provided by a part-time spring. The part-time spring reduces recoil during the primary portion of the rearward movement. The recoil reducer also includes an engager. The engager is operable in response to movement of the slide between the primary and secondary portions of the rearward movement to terminate operation of the part-time spring. The document numbered U.S. Pat. No. 8,539,706B1 comprises a recoil-reducing firearm system a frame, a barrel, a slide, a full-time spring, and a recoil reducer. Said elements are structured separately and related to each other in order to achieve the desired purpose. The slide was adapted for a closing forward movement following the rearward movement. The rearward movement includes a primary portion and a secondary portion. The spring used in the gun is a coil spring and surrounds the barrel. The coil spring functions as a full-time spring. The coil spring is of a reduced value operable for reducing to a maximum of 10 pounds the force necessary for an initial manual pull back of the slide prior to a first shot. The coil spring is adapted to assist in the abating of recoil during the entire rearward and forward movement of the slide following firing. Provided last is a recoil reducing assembly The recoil reducing assembly includes a housing. The housing has a plurality of cupped spring washers within the housing. Cupped spring washers are also known as Belleville washers, coned-disc springs, conical spring washers, and disc springs. The cupped spring washers are provided in combinations of series and parallel for functioning as a part-time spring operable for the abating of recoil during at least a part of the primary portion of the rearward movement of the slide and for the not abating of recoil during the secondary portion of the rearward movement of the slide.

In the state of the art, in the document numbered U.S. Pat. No. 9,644,909B2, it is performed that moving the guide rod down and in front of the trigger, thereby increasing the amount of surface area in the region impacted by the slide during firing and utilizing a firearm configuration that allows the manufacturer to integrate the recoil spring guide rod with the frame. The lower housing includes a guide rod and recoil spring that extend through the opening in the recoil mass. Recoil spring has an end seated within recoil mass. Guide rod was positioned along a third axis. The third axis is positioned below the second axis. Guide rod is integral with the lower housing. In accordance with the present disclosure, when a user fires firearm, the upper housing slides back with respect to the lower housing. This action, in turn, causes the recoil mass to slide along the guide rod to compress the recoil spring. The recoil generated by firearm is greatly reduced by the position and movement of the recoil mass. More specifically, the axis of the recoil spring—i.e. the third axis—is parallel to and below the first axis, which is an axis drawn down the centerline of the barrel prior to the firing of the weapon, and upon which the bullet exits the barrel. In this regard, the first and third axes remain parallel to each other at all times during firing. As a result, the linear momentum generated by ammunition leaving barrel is completely countered by the linear momentum of the recoil mass moving towards trigger. In other words, ammunition leaving barrel travels on a vector that is 180 degrees from the vector of the recoil mass. The recoil mass is positioned below the barrel and the striker assembly. In the second embodiment, the guide rod does not extend through the recoil mass. Instead, the guide rod is replaced by a first guide rod portion that extends from within the recoil mass. Additionally, a second guide rod portion extends from the area in front of the trigger. Recoil mass was adapted for linear movement within second housing and in alignment with trigger. Thus, in the second embodiment, the guide rod does not fully extend within recoil spring. Instead, first guide rod portion extends a short distance within the first end of spring. This reduces the overall weight of firearm without any reduction in the effectiveness of the recoil mass. Accordingly, other configurations, such as an appropriately sized cavity can be used to fix the position of spring.

In order to reduce the recoil force that occurs after firing in the state of the art, it has been tried to solve by changing the structure and shape of the spring on the recoil shaft, however a very effective solution has not been proposed.

The subject of the invention relates to generating a moment by transferring the recoil force on a pin axis after firing in guns (1), rising up the one end of the bolt mechanism (2) and the trigger group (3) independently of the receiver (4) with this moment generated, and returning the end that is risen up (ramped) to the firing position with the springs.

The gun (1) shown in the attached figures most generally consists of the bolt mechanism (2), the trigger group (3), and the receiver (4). The bolt mechanism (2), the trigger group (3), and the receiver (4) shown in the FIG. 3 are connected to each other by means of pins, different from the state of the art. First, the trigger group (3) is seated on the receiver (4) for the recoil force damping system of the present invention. Receiver (4) and trigger group (2) are connected to each other by means of the pins. The gun (1) is mounted by means of passing the receiver (4) and the upper part of the trigger group (3), which are connected, through the rail (5) positioned in the bolt mechanism (2).

For the recoil force damping system, the moment pin slot (6.1) and the pin bearing (7.1) are opened on both sides of the receiver (4). The moment pin slot (6.1) opened on the receiver (4) is located at the rear portion of the receiver (4), while the pin bearing (7.1) is located close to the barrel side. In the Trigger Group (3), which is placed inside the receiver (4), the moment pin slot (6.1) and the pin bearing (7.2) are opened corresponding to moment pin slot (6.1) and the pin bearing (7.1) located on the receiver (4). The pin bearing (7.1) on the receiver (4) and the pin slot (7.2) on the trigger group (3) have different dimensions and are aligned. The pin (7) is passed through the pin bearing (7.1) and the pin slot (7.2). While the pin (7) and the pin slot (7.2) have the same dimensions, the pin (7) can move up and down therein by means of the elliptical shape of the pin bearing (7.1) (FIG. —1).

The moment pin slots (6.1) located on the receiver (4) and the trigger group (3) have the same dimensions with each other, wherein the moment pin (6) is passed between them. After the shot, the force of the bolt mechanism (2) moving backwards with the recoil force creates a moment on the moment pin (6), and the bolt mechanism (2) and the trigger group (3) connected to said mechanism (2) by rails and tabs begin its rotational movement on the axis of said moment pin (6). In this case, the upward angle of the bolt mechanism (2) and the trigger group (3) that risen up simultaneously during firing is limited by means of the movement of the pin (7) in the pin bearing (7.1). Therefore, the bolt mechanism (2) and the trigger group (3) can only be risen up as far as the pin bearing (7.1) allows. In this case, the upward angle of both the bolt mechanism (2) and the trigger group (3) is limited, and the receiver (4) and the trigger group (3) are connected to each other by means of pins the pins.

The bolt mechanism (2) and the trigger group (3), which move upwards during firing, return to their original positions by means of the coil springs (8). First, the screw (9) is passed through the coil spring (8) in order to fix the coil spring (8) to the trigger group (3). Subsequently, the screws (9) are passed through the screw slots (9.1) located opposite to each other at the end of the trigger group (3), and the springs (8) and screws (9) that are nested with the help of nuts (10) are fixed at the appropriate position. In this case, the force created by the moment pin (6) during firing overcomes the force of the coil spring (8) and moves the bolt mechanism (2) and the trigger group (3) upwards as much as the pin bearing (7.1) allows. After the firing process is completed, the tension on the coil springs (8) brings the bolt mechanism (2) and the trigger group (3) back to their original position (FIG. —2). The compression amount of the coil spring (8) can be adjusted with the help of the screw (9) and the nut (10) for the bullets having different caliber sizes as desired by the user.

The system created to damp the recoil force in the guns (1) can also be provided with the alternative production in FIG. 6. The bolt mechanism (2), trigger group (3), and receiver (4) in FIG. —3, which are the subject of the invention, are connected in the same manner in the alternative production in FIG. 6. The bolt mechanism (2) and the Trigger Group (3), which move upwards during firing, return to their original positions with the spring (11) in alternative production. First, the spring pin slot (11.2) is opened on the receiver (4) in a position close to the barrel, again opposite to each other in order to place the spring (11). As seen in FIG. 6, the spring (11) is u-shaped and has a gap at both ends where the spring pin (11.1) can pass through. It is ensured to be connected by passing the spring pin (11.1) through the spring (11) which is placed in line with the spring pin slots (11.2) inside the receiver (4). In this case, the force created by the moment pin (6) during firing overcomes the force of the spring (11) and moves the bolt mechanism (2) and the trigger group (3) upwards as much as the pin bearing (7.1) allows (FIG. —5). After the firing process is completed, the tension on the spring (11) brings the bolt mechanism (2) and the trigger group (3) back to their original position (FIG. —4).
