TECHNICAL FIELD

The invention relates to the locking mechanism that controls the utilization of the compressed air, which ensures the operation of the hammer (cock), that is employed in PCP (pre-charged pneumatic) rifles, guns, and all air rifles generally used for hobby, sports, and hunting purposes.

PRIOR ART

PCP, namely pre-charged pneumatic, is a definition made up of the initials of English words. This air rifle, which has an integrated air tube with a pressure between 70 and 300 bar, which is generally used for sports, hobby and hunting purposes, has higher pressure than normal air rifles and allows faster firing. It is possible to make an average of 50 - 150 shots with a single charge. These rifles operate on the principle of shooting by transmitting the previously filled compressed air to the barrel with the help of hammer mechanism when the trigger is pressed.

PCP rifle, which is made ready for shooting by pulling the cocking lever and thus enabling the trigger and hammer mechanism to be set, releases the hammer mechanism when the trigger is pressed. The hammer mechanism that is released opens the valve by making linear movement by being pushed with the help of the spring. Thus, the compressed air is transmitted to the barrel and the shot is completed. However, since the energy on it is not reset while the hammer returns, it moves forward again with the thrust force created by the compressed spring, opens the valve, and continues to evacuate the air. This situation continues until the kinetic energy of the hammer and spring is reset. Thus, air evacuation after shooting continues, thus reducing the number of shots that can be made. Another issue is to achieve stable muzzle velocity and shot grouping in PCP rifles. In the mechanism we have described above in the known technique, due to the fact that the hammer opens the valve before the ammunition leaves the barrel, there are inconsistency in the firing rates and problems of rearing in the rifle before the movement of the ammunition, due to the compressed air going back to the barrel. This is a very compelling and dangerous situation for the shooter. FIGURES

DETAILED DESCRIPTION OF THE INVENTION

The invention consists of cocking lever (1 ), transfer pin (2), hammer spring (3), hammer (4), dummy (5), operating latch (6), trigger (7), valve (8), valve spring (9), hammer lock (10), magazine operating lever (11), hammer lock spring (12) and latch spring (13).

The gun is set via the cocking lever (1 ). While the gun is being set, the hammer (4) is pulled back with the transfer pin (2) coming from the cocking lever (1 ), thus enabling the trigger mechanism (7) to be set. After the trigger mechanism (7) is set, the rifle is set as a result of the hammer (4) and the dummy (5) holding it. At the same time, the magazine operating lever (11 ) both sets up the mechanism and the control system consisting of the hammer lock (10) and the hammer lock spring (12), which is the subject matter of the invention. The process of setting up the control system consisting of the hammer lock (10) and the hammer lock spring (12), which is the subject matter of the invention: while the operating lever (11 ) moves backwards, it moves the hammer lock (10) downwards. After reaching a certain distance, it releases the operating latch (6), which operates the control system consisting of the hammer lock (10) and the hammer lock spring (12). The released operating latch (6) is pushed forward with the latch spring (13) behind it and holds the hammer lock (10). Now the system is set and it ready for firing. As soon as the trigger mechanism (7) is squeezed, the hammer (4) is released from the dummy (5) and it gains linear motion and is energized thanks to the hammer spring (3) behind it. When the hammer (4) passes the hammer lock (10) sufficiently, it both moves the operating latch (6) and strikes the valve (8), and causes the valve (8) to move. Thus, it ensures that the compressed air/gas in the system is transmitted to the barrel and moves the ammunition, and causes it to leave the barrel. While this process is taking place, the hammer (4) and the valve spring (9) located behind the valve (8) are pushed back as a result of action-reaction. As soon as the operating latch (6) moves in the operation direction, the hammer lock (10) enters between the hammer (4) and the valve (8), thanks to the lock spring (12) on its lower part. The hammer (4) consumes the energy generated by the reaction of the valve (8) to rebound, and then, it gains movement towards the valve (8) thanks to the hammer spring (3) located behind itself. However, now the hammer lock (10) is located between the valve (8) and the hammer (4). Since the contact of the hammer (4) and the valve (8) is no longer possible, the hammer (4) is prevented from opening the valve (8) and evacuating the compressed air/gas. Thus, since the compressed air is not released except for the shot, wastage is prevented. Since the valve (8) does not open and does not give air again before the ammunition leaves the barrel, the muzzle velocity of the ammunition is stabilized. This, in turn, enables better shot grouping. It gives the shooter a stable and comfortable shooting opportunity during firing. Since air evacuation is not possible other than during the shot, the number of shots increases significantly.
