Description

BRIEF PRESENTATION [001] This patent application relates to a recoil and vibration damping system designed to be incorporated into components or coupled to firearms or air guns. The present invention consists primarily of a system with damping walls made of elastomers, rubbers or solids, configured to support or contain a high-density mass, whether solid or an agglomeration of particulates or spherical masses. The present invention operates effectively in attenuating vibrations and recoil during firing or movement of moving parts of the weapon, which improves the accuracy and comfort of the user when operating it. The system can be mounted as a component coupled to the weapon or integrated into its moving parts, such as pistons, actuators, hammers, among others. Another distinguishing feature of the present invention lies in the ability of the present system to absorb and dissipate the energy generated by recoil and vibrations in multiple axes, thus configuring itself as an adaptable solution for different models and conditions of use of weapons. FIELD OF THE INVENTION [002] The invention described in this patent application is aimed at the arms and arms accessories sector, specifically in the development and manufacture of devices and parts for firearms and air guns. The recoil and vibration damping system applies both to improving the usability and performance of personal weapons and in military and security applications, where precision and control during firing are crucial. BACKGROUND OF THE INVENTION [003] Namely, tuned mass dampers are known in a variety of applications, such as attenuating seismic vibrations in buildings, automotive systems, and the aerospace industry. In buildings, they typically consist of a large solid mass supported by springs or pneumatic systems that compensate for oscillations in the structure. In the energy sector, wind turbines use a similar approach to contain oscillations caused by the blades. Stockbridge-type systems are commonly used to reduce oscillations in overhead power lines between power towers, aiming to mitigate short-circuit risks. [004] In the automotive industry, mass dampers were applied by Renault to its F1 car in 2005, aiming to increase vehicle stability through a system similar to that used in buildings, and are also used in production cars to control crankshaft vibrations by means of a ring-shaped mass supported by silicone. In the aerospace industry, NASA applied this approach to Ares rockets to attenuate booster vibrations. [005] In weapons, some devices use this principle to solve recoil and vibration problems. Recoil neutralizing devices based on high-density liquids, which consist of a closed steel casing partially filled with a dense liquid (usually mercury), such as those produced by C&H Research, rely on a liquid mass that collides against the walls of the casing and attenuates the initial vibrations of the shot. [006] In the firearms field, one approach uses the gases generated by the gunpowder explosion to create a countermovement through a piston. Another strategy conventionally employed to attenuate recoil in firearms involves the use of springs with shafts fixed to the stock and body of the weapon to absorb recoil at the moment of firing. PROBLEM TO BE SOLVED [007] It is known to experts in the field that recoil and vibrations are significant problems for high-performance shooting with firearms and air rifles, as they interfere with the shooter's control of the weapon and can affect the base on which the weapons are mounted. This problem becomes even more serious in weapons with more intense vibration, such as high-powered weapons and "spring" type air rifles that have to deal with the final impact of the piston. STATE OF THE ART [008] Based on the shortcomings discussed above, it was possible to obtain patent references such as document US4112605A, published on 12/09/1978, which describes a recoil reducer for weapons, particularly shoulder-fired weapons, comprising an elongated sealed cylinder partially filled with a heavy liquid, such as mercury, and divided into at least two chambers by a partition structure formed with a restricted orifice through it, so as to retard the forward movement of the mercury from the rear to the front chamber when the weapon recoils, the reducer preferably being mounted on the pistol with its rear end lower than its front end, so that the rear chamber is filled against the front wall of the cylinder and the rear surface of the partition in opposition to the rearward movement of the pistol during recoil, combining with the retarded flow of liquid through the orifice connecting the rear chamber to the front chamber, to absorb a large part of the recoil energy. [009] Document US4503632A, published on 12/03/1985, describes a recoil reduction mechanism for use in shotguns. The mechanism utilizes explosive gases from the shotgun barrel that are carried through gas passages to a chamber within an attached cylinder. T
