Operating system utilizing an articulated bolt train to manage recoil force

Abstract

An Operational System for Firearms founded on the use of the synchronic controlled motion and cooperative interaction of elements of a Pivotally Articulated Bolt Train displacing reciprocatingly within a compliant receiver, along guiding means, disposed according to a purposely engineered Path, capable of generating anticipated adjustable dynamic reactions, and to execute mechanical actions, due to pre-calculated movements of interconnecting mechanisms within said Train members, when they pivot one relative to the other. The alternate divergent and converging motion of the Train Bolt and A Firing Mechanism Carriage subassembly, along a horizontal path, and a transverse path, modifies and splits the linear bearing of the recoil force, and generates a Gyroscopic Effect or Angular Moment, decreasing the Barrel Torque magnitude, conveying a unique tailored dynamic behavior, while performing different functions and achieving the eleven different purposes of this invention. Numerous motion parameters are adjustable to attain the distinctive recoil Dynamic reaction.

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a Continuation-in-Part of co-pending U.S. patent application Ser. No. 13 / 385,262, filed on Feb. 2, 2012, which claims the benefit of Provisional Patent Application Ser. No. 61 / 463,034 filed on Feb. 11, 2011, now expired. The entirety of both the co-pending non-provisional and expired provisional applications are herein incorporated by reference.FIELD OF THE INVENTION[0002]This application relates generally to a firearm operational system improvement, describing an Articulated Bolt Train mechanism in which The Head Bolt moves linearly aligned with the axis of the barrel and the second train member, the Firing Mechanism Subassembly, may have a movement component perpendicular to the barrel axis in certain sectors of the Motion path when it changes the bearing, from horizontally aligned with the axis of the barrel, to a transverse, through the handle direction. This redirection of the path causes significant reaction forc...

AI Technical Summary

Benefits of technology

The patent describes a firearm with a unique operating system that manages recoil by changing the dynamic behavior of the weapon when firing. The system includes a track-mounted pivotally articulated bolt train that moves reciprocatingly along a pre calculated path, engineered to redirect forces, create delays, decelerate motion, absorb energy, and lower the center of gravity, resulting in improved handling of the gun. The system also includes several modular subassemblies, a barrel, a receiver, an articulated bolt train, an active firing mechanism, a delay blowback method, a controlling firing mechanism, a set of main recovery springs, a set off modular multifunctional supports, a buffer mechanism, a Modular Cocking Handle mechanism, and a direct drive gas system. The unique dynamic behavior of the firearm allows for smooth recoil control and is adaptable to different applications.

Problems solved by technology

However, none of the previous patents uses the active firing mechanisms as part of the moving recoiling mass displacing transversally.

Nor it uses an active recoil damper mechanism.

However the different means used to achieve the recoil absorption are significantly inefficient in terms of the volume and total weight required.

None of the design solutions involve the use of firing mechanisms displacement or the use of the firing mechanisms mass as a part of the recoiling inertial mass.

It is notorious for being voluminous and unwieldy.

And furthermore, the array of mechanisms condemns the operation, in practical reality, to small pistol cartridges.

It causes a delay in the breech opening by means of a complicated mechanism inside the bolt whereby a set of sprig loaded rollers are forced to move along a pair of closing arc circle surfaces generating a retention of the force produced by the increasing gas pressure inside the barrel until the point where it overcomes the force of the rollers mechanism, generating a delay.

The use of such mechanism has been successful, but has several disadvantages: it is sensitive to dirt, it requires lubrication, rollers break, springs fatigue, and does not lend to trimming.
