TECHNICAL FIELD

The invention relates to a recoil damping system for firearms with high gas pressure and heavy cartridge/bullet weight.

PRIOR ART

Recoil system in firearms; generally defined as an operating system in which the energy to operate the various mechanisms of the firearm and automate the loading of another cartridge is derived from the inertia of the spent shell casing. When the gun is fired, the bullet is pushed in one direction by the gunpowder explosion; in return, the rifle is pushed back and recoil is created. The factors affecting the recoil can be listed as follows;

• Weight of the rifle

• The weight of the cartridge and the powder charge

• Barrel diameter

• Muzzle velocity.

Recoil decreases as the weight of the rifle increases, while recoil increases as other factors increase. Physically it is possible to calculate the recoil via a formula. Recoil decreases as the weight of the rifle increases, while recoil increases as other factors increase. Physically it is possible to calculate the recoil via a formula. In this formula, the recoil energy is calculated by dividing the square of the sum of the product of the cartridge weight and the muzzle velocity of the cartridge, and the product of the powder charge and 4700, with the product of the weight of the gun and 64.4. Values here should be taken in pounds.

There is a difference between the measured and felt (perceived) recoil. Physics formulates the action of the weapon and what the result is. However, since the recoil perceived by the shooter is also related to the mental and physical condition of the shooter, the felt recoil force varies from person to person. The main factors here can be listed as follows;

• Suitability of the weapon to the shooter • Shooter's experience

• The shooter's mental and physical condition at that moment

• Type of weapon (pump-riffle, semi-automatic= gas or kinetic energy)

• Recoil-reducing supports or apparatus

• The thickness of the shooter's suit

• The intensity of the sound of the gun, startle response

• Suggestions made to the shooter about the recoil of the gun

As we explained above, it is clear that recoil as a physical force is related to the barrel diameter and the cartridge used. Pads are used in today's rifles to reduce the load on the shooter's shoulder caused by the recoil force. Although the pad absorbs some of the incoming force during recoil, it cannot be successful in rifles with high gas pressure and heavy cartridge weight. For this reason, this type of weapon is preferred by physically strong shooters.

It has been reported by shooters that an additional 33 percent more recoil of the 89 MM cartridge is painful when several shots are fired with both 76 MM and 89 MM cartridges, with a 3-kilo 400-gram rifle containing the pad used to prevent the current recoil. It was also reported that the shooters agreed that the 89 MM cartridge made the rifle more difficult to handle. Almost all shooters complain of the pain and recovery time of heavy recoil after shooting.

BRIEF DESCRIPTION OF THE INVENTION

The invention relates to a recoil damping system, which includes at least one spring tube with variable stiffness, which can be easily attached and detached, absorbing the severe recoil in firearms with high gas pressure and heavy weight cartridges/bullets. In the system in question, the impact on the shooter's shoulder is minimized by the spring tubes absorbing the severe recoil that occurs in firearms with high gas pressure and heavy-weight cartridges/bullets at the maximum level, in contrast to the known technique. Thus, after the shot, the pain and injuries caused by the severe recoil are not in question any longer. The invention is a practical recoil damping system that is compatible with all firearms, can be easily attached and detached, and can be applied with spring tubes of variable stiffness.

DETAILED DESCRIPTION OF THE INVENTION

The invention consists of inner body (1 ), outer body (2), spring tube channel (3), spring tube (4), connecting cam (5), pad (6) and lock system (7) parts. The lock system (7) includes the locking latch (7.1 ) and the lock slot (7.2).

The recoil damping system, which is the subject of the invention, is characterized by the spring tubes (4) placed in at least one spring tube channel (3) located on the inner body ( 1 ) and outer body (2) on both sides of the connecting cam (5) in a manner that there is a distance between an inner body (1) and an outer body (2) so that inner body (1 ) can move back and forth on the connecting cam (5) of the outer body (2). There is a pad (6) on the outer body (2) for the shooter to place the rifle on his shoulder and to have a comfortable grip. There is a lock system (7) located on the inner body (1 ), which allows the assembled set to be easily attached and dismounted from the butt of the rifle. The recoil damping assembly set, which is placed in the lock slot (7.2) on the butt, is locked to the butt with the help of the lock latch (7.1 ), and thus becomes ready for operation. The invention, which is suitable for firearms with high gas pressure and heavyweight cartridges/bullets, is used by selecting the appropriate stiffness from the spring tubes (4) and placing them in the spring tube channel (3) according to the barrel diameter of the firearm used, the type of cartridge and the powder charge. After the shooter fires, the recoil force that is created while the firearm mechanism moves rearwards by the inertia created when the buckshot is pushed forward in the barrel as a result of rifle firing the gunpowder comes to the inner body (1 ), which forms the contact surface with the rifle butt. The inner body (1 ) transmits the recoil force to the spring tubes (4), which are placed in the spring tube channels (3), selected with the stiffness suitable for the barrel diameter, type of cartridge, and the powder charge. While the recoil force is damped in the spring tubes (4), the inner body (1 ) moves on the connecting cam (5) as much as the compression ratio in the spring tubes (4). Thus, most of the recoil force generated is damped and the remaining part is transferred to the outer body (2), and the shooter completes his shot without suffering pain and without injury with the help of the pad (6) on his shoulder.

Our invention provides comfort to the shooter by minimizing the injury and the shoulder pain suffered as a result of recoil, which is the biggest obstacle to the preference of firearms with high gas pressure and heavy-weight cartridges/bullets by the shooters. In addition, this type of firearm gives the shooters, whose physical strength is not sufficient, the opportunity to experience this pleasure.

The fact that the invention can be applied to a firearm with high gas pressure and heavy-weight cartridges/bullets, and that it can be easily assembled and disassembled, and that the spring tubes (4) can be easily changed according to the recoil hardness and the user's preferences during the shooting in the hunting area and for sports purposes, are among the most important factors that facilitate its use.
