Description

[0001] COCK CONFIGURATION IN SINGLE SHOT AND BREAK ACTION RIFLE

[0002] Technical Field

[0003] The invention relates to the cock configuration of single shot and break action rifle, which provides user safety by coming into the safety position after the barrel is closed.

[0004] Prior art

[0005] In single shot and break action rifle, which are generally used for hunting and sport shooting, the barrel is opened (broken) from the receiver by the user by separating / rotating the joint from the axis, allowing a new cartridge to be inserted into the rifle. General principle of use of a break-barrel rifle:

[0006] Barrel Opening(breaking): the user opens the barrel of the rifle by separating it from the receiver. This usually takes place around the joint or axis at the bottom of the barrel.

[0007] Cartridge Loading: When the barrel is opened, the user places a new cartridge into the rifle.

[0008] Barrel Closure: after the cartridge is inserted, the user closes the barrel back towards the reciver. This is the step that activates the firing mechanism and makes the rifle ready for firing.

[0009] Trigger Pull and Firing: When the trigger is pulled, the firing mechanism is activated. This mechanism usually includes a trigger mechanism and releases the firing pin when the trigger is pulled. The firing pin fires the cartridge.

[0010] Ignition and Cartridge Explosion: The firing pin lights the cartridge and activates the igniter inside the cartridge. This starts an ignition process that causes the cartridge to explode and eject from the barrel.

[0011] The user can then open the barrel again to remove the empty cartridge and insert a new cartridge.

[0012] A rifle that is ready to fire when the barrel is closed posed a security risk. In order to prevent this risk, some safety measures have been taken in rifles. The most commonly used safety measures are the safety pins, which secure the rifle by directly interfering with the trigger.

[0013] However, these safety pins, which are activated by the user's initiative and intervention, cause many accidents due to the users' absent-mindedness, forgetfulness and so on.

[0014] Aim of the Invention

[0015] The main purpose of the invention is to provide a cock configuration with increased safety in single shot and break action rifles.

[0016] Another object of the invention is to provide a self-securing cocking configuration without user intervention.

[0017] Another object of the invention is to reduce the amount of force required for the cocking spring which actuates the cocking configuration with increased safety.

[0044] The cock configuration mainly consists of the cock(3) the stages(7)and cock spring(4) created on the cock. The main problem solved by the invention is that during the opening of the barrel, the cock(3) simultaneously changes its position and moves to the safety position.

[0045] The main element of the invention is a cock(3) connected to the receiver(2) by means of a cock pin(6) and rotatable in the axis of the cock pin(6). (Figure 3 - 5) When the barrel is opened / broken, the lock(9) pushes the cock(3) from a place above the cock pin(6) and the cock(3) rotates in the "a" direction on the axis of the cock pin(6). The trigger(lO) engages in the first of the stages(7) formed on one end of the cock(3) (Figure - 3) The other end of the cock(3) touches the cock spring(4) and compresses the cock spring(4). However, the amount of compression of the cock spring(4) and the force accumulated in the cock spring(4) is not sufficient for the cock(3) to strike the firing pin(8) with sufficient force to fire the rifle if the cock(3) is released. In this way, the rifle (1) is automatically secured upon closing the barrel.

[0046] In order for the rifle(l) to be ready for firing, the cock(3) must compress the cock spring(4) more and thus the force / stress accumulated in the cock spring(4) must increase. In order to achieve this, a cock lever(5) is formed on the end of the cock(3) that is outside the receiver(2) (Figure 2 - 4) When the cock lever(5) is pulled manually by the user, the cock(3) rotates in the a-direction on the axis of the cock pin(6) and compresses the cock spring(4) more. In the meantime, the trigger(lO) is released from the first stage(7) and engages the second stage(7). (Figure - 5) In this way, the cock(3) is cocked and the rifle(l) is ready to fire.

[0047] When the user presses the trigger(lO), the cock stage(7) is released from the trigger(lO) and the trigger(lO) releases the cock(3). The cock spring(4) rotates the cock(3) in the "b" direction on the axis of the cock pin(6), causing the cock(3) to strike the firing pin(8) and the rifle(l) to fire.

[0048] Another unexpected effect of the invention is upon the cock spring(4). Due to the force lever principle, as the point where the cock spring(4) exerts force on the cock(3) moves away from the cock pin(6) in other words, as it goes further away from the cock pin(6) the amount of force required to fire the rifle(l) decreases. As the barrel is closed, the lock(9) pushes the cock(3) from a place above the cock pin(6), so the cock spring(4) is positioned above the said lock(9). This resulted in moving away from the cock pin(6). In this way, the force of the cock spring(4) required for the rifle(l) to fire is reduced. According to Hooke's law, the spring force depends on the amount of compression and the spring constant of the spring material. Therefore, since the force required to fire the rifle is constant, the desired result can be achieved by compressing the cock spring(4) less or by using a spring made of a material with a lower spring constant and therefore lower cost.

[0049] In order for the invention to work, a lock(9) that will push the cock(3) from aplace above the cock pin(6) when the barrel is closed is sufficient, and a lock design with the details described below can also be used in the application of the invention. The trigger guard(ll) is connected to the receiver(2) by a pin(12). Thanks to its connection with a single pin(12), the trigger guard(ll) can move circularly on the axis of the pin(12). In the invention, it is aimed to move the lock(9) horizontally by utilizing the circular movement of the trigger guard(ll). For this purpose, a lock lever(13) extending into the receiver(2) is formed in the part of the trigger guard(ll) inside the receiver(2).

[0050] The lock lever(13) is rod-shaped and extends into the reciver(2) as mentioned above. The lock lever(13) passes through the lever housing(14) formed on the lock(9), which is horizontal inside the receiver(2). A structure in the form of a joint(16) is formed on the lock lever (13). Since the joint diameter is equal to the diameter / width of the lever housing(14), each movement of the lock lever(13) can move the lock(9). In this way, the circular movement of the trigger guard(ll) is transferred to the lock(9) by the lock lever(13) and the horizontal movement of the lock(9) is ensured. Therefore, when the teigger guard(ll) is rotated in "a" direction, it can move the lock(9) in the "z" direction.

[0051] When the lock(9) is retracted into the receiver, in other words, when it moves in the "z" direction, the lock ends on the lock end are released from the lock housing on the barrel and the barrel can be opened / broken.

[0052] A lock spring(15) is placed at the other end of the lock(9) so that the lock(9) can return to its initial position. The lock spring(15) can stand independently at the other end of the lock(9), or it is preferably placed in the lock spring housing(17) formed in the lock(9). In this way, the position of the lock spring(15) is maintained. The lock spring(15), which is compressed when the lock(9) moves in the "z" direction, opens when the user releases the trigger guard(ll) and pushes the lock(9) in the "y" direction and returns it to its original position. This movement of the lock(9) also pushes the lock lever (13), which moves the trigger guard(ll) in the "b" direction and returns the tirgger guard(ll) to its initial position.

[0053] On the lock (9) there is a cock housing(18) through which the cock(3) passes. The cock(3), which is mounted on the cock pin(6) and rotates on the axis of the said pin(6), passes through the said cock housing(18), one end resting on the trigger(lO) and the other end resting on the cock spring(4).
