The present invention relates to a new firearm mechanism that is designed for both shotgun and rifle structures, enables to shoot rapidly and has a high shooting power thanks to the structure that it has.
Firearm structures are typically grouped as rifles and shotguns in the state of art. Rifles has a structure in which interior surface of the barrel is comprised of rotative lines that are symmetrical to each other. Rifles has a higher firepower, therefore increasing hit ratio due to the fact that interior surface of the rifle barrels are in a rotative form. Yet, interior surface of the barrel is smooth in shotguns. This negatively affects hit ratio, firepower and shooting range.
There is a lot of firearm structures known from the state of art. These firearm structures may comprise firing mechanisms comprised of different components and arrangements. Said mechanism structures carry out respectively various processes. Taking new cartridge, which is to be fired in the firearm structures enabling to shoot successively without interfering, from magazine structure and positioning it into the barrel is one of the processes that said mechanisms carry out. Firing a cartridge by means of a pin in its structure hitting onto percussion cap can be given as another example for the processes that mechanisms carry out Lock system, which enables powder gas resulting from the cartridge fired to push bullet or shots, constitutes an example for component groups in firearm mechanisms. The mechanism structures may be in different shapes such as rotative head, ball etc.

The invention relates to a new mechanism structure designed for both rifles and shotguns, comprising a lock system that works in a perpendicular position, with a lower recoil level and having an increased firing power by means of a small amount of gas leak.
Mechanism structure, the subject matter of the invention, comprises a mechanism blog carrying out the firing process. Exploded view of said mechanism group can be seen in
Mechanism group existing in the central position of mechanism structure subject to the invention is positioned such that it exactly coincides with the back portion of the barrel (61) structure. Mechanism group, as also can be seen in
Connection of the mechanism head (14) with the mechanism right cover (8) and mechanism left cover (6) is realized by means of two mechanism mounting pins (15). Said mechanism mounting pins (15), as can be seen in
Said movement holes (17), as also can be seen in
As can be seen in
Firing pin (5) structure, to which cock structure strikes to start the firing, are positioned in the firing pin housing (30) on the back surface of mechanism head (14), in case the firearm structure in which the mechanism structure subject to the invention is triggered so as to be fired. Said firing pin (5) enters through firing pin housing (30) on the back surface of mechanism head (14), however end portion of firing pin (5) may stick out of firing pin cavity (27) on the front surface of the mechanism head (14). End portion of firing pin (5) that may stick out of firing pin cavity (27) is thinner than its remaining section.
A firing pin spring (13) is located in the section in which the thinner end of firing pin (5) structure positioned in the mechanism head (14) exists. Firstly, the firing pin spring (13), then the firing pin (5) enters in firing pin housing (30). Objective of said firing pin spring (13) is to enable the firing pin (5) moving forward so as to carry out the firing process to take back its old position. There is a tether pin housing (35) at the point close to upper edge of the side surface of mechanism head (14). After the firing pin (5) is positioned in the firing pin housing (30), a tether pin for firing pin located in the tether pin housing (35) and firing pin (5) structure are fixed into the mechanism body (14). There is some space in the section which tether pin for firing pin (11) coincides with on the upper of portion of firing pin (5). Tether pin for firing pin (11) is placed on said tether bearing (18) on the firing pin (5). Thus, Firing pin (5) structure forced to move with the effect of firing pin spring (13) while in a normal position may stay in firing pin housing (30) because tether pin for firing pin (11) exists in tether bearing (18). Said tether bearing (18) on the upper surface of firing pin (5) expands slightly towards rear end of firing pin (5) structure. Therefore, there is some space at the back portion of tether pin for firing pin (11). In the course of firing, when firing pin (5) moves forward, tether pin for firing pin (11) moves along the tether bearing (18) and does not prevent firing pin (5) from moving.
While placing oppositely mechanism right cover (8) and mechanism left cover (6) at sides of mechanism head (6), a recoil spring tube (4) is placed exactly on the mechanism head (6) such that it coincides with between upper edges of mechanism right cover (8) and mechanism left cover (6). As can be seen in
There is a rod housing (39) in the form of cylindrical space expanding inward at the end portion facing to opposed side of barrel (61) of the recoil spring tube (4). There is another space structure with smaller diameter at the end facing to barrel (61) of the recoil spring tube (4). Guide rod (1) that can be seen in
Guide rod (1), together with the recoil spring (2) thereon, is positioned in rod housing (39) at the back section of recoil spring tube (4) such that it is the end with spring plate (3). Diameter of the space at frond side of recoil spring tube (4) is smaller than diameter of spring plate (3). Therefore, the spring plate (3) positioned in recoil spring tube (4) at the end of guide rode (1) cannot stick out of the end at the front side of recoil spring tube (4). Main objective of the guide rod (1) is to guide the recoil spring (2) ejecting empty cartridge in the chamber and loading a new cartridge in the barrel (61) in the course of firing, and enabling to take back its location in the normal position by pushing the mechanism sliding backward so as to cock firearm from back side of the firearm towards front side in which the barrel (61) takes place.
There is respectively one extractor housing (33), which is positioned symmetrically according to each other in both sides, at the front side in wide end portion of mechanism head (14). Extractor housings (33) are inward space structures on the side surfaces of mechanism head (14). Extractor (9) structure that can be seen in
Extractor (9) structure, as can be seen in
There is a spring protrusion (48) facilitating the extractor (9) to move at the back end, which is in a opposite direction of barrel, of extractor (9) structure positioned in extractor housing (33) by means of extractor pin (12). Spring protrusion (48) coincides exactly with the extractor spring cavity (32) when extractor (9) structure is positioned in extractor housing (33). Extractor spring cavity (32) is on the back end of extractor housing (33). Extractor spring (10) is positioned in extractor spring cavity (32). Thus, extractor spring (10) remains between extractor spring cavity (32) and spring protrusion (48). Extractor (9) structure may conduct circular movements depending on jamming and expanding movements of extractor spring (10) such that it takes the extractor pin (12) as the center.
Extractor (9) structure is at the end on front side of mechanism head (14). Since the location in which mechanism head (14) exists is the very back portion of barrel (61) structure, the extractor (9) structure stays exactly behind the barrel (61) structure. Even end portion of extractor (9) structure facing towards the barrel (61) makes a contact with the cartridge structure positioned in the barrel (61) so as to be fired. There is a cartridge holding protrusion (45) in the inward protruding form, which can be seen in
Main objective of the extractor (9) is to move the empty cartridge case that remains in the barrel backward by means of mechanism after firing processes is conducted. It is possible to move the empty cartridge case by means of cartridge holding protrusion (45) and cartridge base space (47). Extractor (9) enables the empty case to strike to ejector by moving the empty cartridge case backward and to eject it out of firearm structure.
There is a lock protrusion (23) in the protruding form that looks like a triangle when looked from top, as can be seen in
Mechanism head (14) enables to shoot the bullet through barrel (61) by pushing it by means of gas pressure arisen from the explosion of the cartridge in the barrel by fastening to barrel (61). Mechanism head (14) moves downward and forward traversely during its movement towards the barrel (61) thanks to its design, wherein it is locked to barrel (61) by moving upward and backward in the axis of movement holes (17) after its movement towards barrel (61) is finished. Mechanism head (14) prevents powder gas pushing bullet or shots from leaking by delaying first movement of mechanism pushed back after cartridge is fired until bullet or shots leave the barrel (61). At this point, firstly lock protrusion (23) on the mechanism head (14) leaves from the lock housing (51) on lower surface of mechanism rail (50) therein. After that, mechanism head (14) moves downward. It moves backward as a whole with the components in mechanism head (14) after mechanism head (14) and mechanism rail (50) separate from each other. Mechanism head (14) enables to position both lock and cartridge in barrel (61) by way of pushing them.
There is magazine disc (52) at the front end facing to barrel (61) of mechanism rail (50). Back end of the barrel (61) exists in the magazine disc (52). As can be seen in
There is a barrel crown (53) structure immediately in the front portion of mechanism rail (50) and magazine disc (52) in a mounted to each other form. The barrel crown (53) that can be seen in
Push tube (57) is positioned on the barrel (61) structure such that it coincides with immediate front portion of recoil spring tube (4). Back end of the push tube (57) stays in the barrel crown (53). Push tube (57) moves mechanism head (14) backward by pushing the movement obtained from gas piston (42) in the gas chamber (41) at its front side to recoil spring tube (4) in the course of firing. In case of a normal position without firing, while recoil spring tube (4) and push tube (57) do not make a contact with each other, the movement arisen by means of gas pressure in the course of firing opens the lock and feeds the firearm by contacting subsequently these three component to each other.
There is a push spring (54) on the push tube (57). Push spring (54) is positioned on the push tube (57) such that it is at the back portion thereof. A cocking handle segment (55) is attached in front of push spring (54). Cocking handle segment (55) restricts movements of the push spring (54) and prevents push tube (57) from releasing from its front end. Since back end of the push spring (54) enters in the barrel crowns (53) along with the push tube (57), push spring (54) is squeezed between cocking handle segment (55) and recoil spring tube. Main objective of the push spring (54) is to enable the push tube (57) moving from front side towards back side to take its first position by means of the effect of movement obtained from gas piston or cocking handle (58).
Since cocking handle segment (55) has a smaller diameter than the cocking handle protrusion (25) in the protruding form on the push tube (57), it is not possible to go over the cocking handle protrusion (25). There is cocking handle housing (26) on side surface of the section in which cocking handle protrusion (25) exists. Cocking handle housing (26) is the structure in which cocking handle (58) is positioned. Cocking handle segment (55) fastens cocking handle (58) into cocking handle housing (26) by means of pushing the cocking handle segment (5) at the front side of push spring (54).
Cocking handle (58) basically enables to cock the firearm by drawing mechanism backward by a user, to load cartridge in the barrel and make it ready to fire. It has an ergonomic design which user can easily move with his/her finger. It can be attached to right side or left side according to user's preference thanks to symmetrical design of the cocking handle housing (26).
A tube lid (60) is attached to front end of the push tube (57) structure. Said tube lid (60), as can be seen in
As can be seen in
Both free ends of push rail (56) enter separately in two push rail housing (28) on the barren crown (53). Therefore, push rail (56) structure is in a stabilized position. Main objective of the push rail (56) is to move push tube (57) in a parallel direction to the barrel (61) axis. It appoints the movement axis of push tube (57).
There exists gas chamber (41) immediately in front of free end of facing to barrel (61) muzzle of the tube lid (60) that is positioned in the front portion of push tube (57). Gas chamber (41) is positioned on the barrel (61) structure. There exists gas piston (42) exactly in the middle of gas chamber (41). Gas piston (42) is the leading one of structures initiating the movements which the mechanism carries out with the effect of gas pressure arisen from firing. Gas piston (42) both exists in gas chamber (41) and is positioned such that its back end is exactly in front of tube lid (60). Therefore, it allows tube lid (60) to move push tube (57) backward by striking to tube lid (60) in the moment in which it moves backward with the effect of gas pressure. Thus, the push tube (57) moving backward strikes to recoil spring tube (4) at its back. Recoil spring tube (4) enables firing circle to be completed by means of transmitting the movement obtained from push tube (57) to the mechanism. At this point, recoil spring (2) allows the mechanism sliding backwards by the drive obtained from the push tube (57) to move back towards barrel (61) and be locked.
There exists a gas hole (40) in the area taking place on the barrel (61) in the interior surface of gas chamber (41). Said gas hole (40) transmits the gas in barrel (61) to the gas chamber (41). There exist multiple discharge holes (44) positioned to be at least one on the upper surface of gas chamber (41) which does not make a contact with the barrel (61) and faces outwards. Main objective of the discharge holes (44) is to discharge the excessive gas and to enable gas residues/particles entered in gas chamber (41) to be discharged in case there is too much burnt powder gas filled in the gas chamber (41). Thus, it is ensured that gas chamber (41) gets dirty later than the usual, and to increase the firing number that requires cleaning. There exists a gas chamber lid (43) at the end portion of gas chamber (41) facing towards end of the barrel (61). Gas chamber lid (43) keeps gas chamber (41) closed. It is fastened by means of lid pin (62).
It is provided a new mechanism that can be used in both rifles and shotguns by means of the mechanism structure subject to the invention. It is provided a structure with higher efficiency by means of designs of the components which constitute the structure of said mechanism. It is provided a new firing power increased mechanism by means of structures that are employed during use of gas pressure and said structures' interaction with each other.
