Abstract

An improved firearm having an Pivotally Articulated Bolt Train assembly consisting of a series of linked carriages, containing firing mechanisms, placed inside a compact ergonomic jaw articulated receiver, holding all the sub assemblies in the convenient location, synchronizing the movements of all the components, and controlling its alternating motion by displacing along divergent and converging paths and tracks, where the Bolt Train, moving through tracks, displaces to align, entirely horizontally, with the barrel axis, rapidly shifting into a curved and transverse path. Such motion forces the cocking, the partial displacement into a Handle Tunnel, and modifies the bearing of the recoil force, conveying a unique dynamic behavior. When displacing rearwards it generates a dual transient angular momentum vector helping to compensate the “barrel Torque” phenomenon caused by the bullet rifling when fired. The interaction of several components delays the breech opening, decelerating the rearwards motion to assist the recoil damping.

Claims

1. A firearm comprising a barrel end, a back end opposite said barrel end, a trigger mechanism, at least one internal channel guide having a front end and a back end such that said front end is closer to said barrel end than said channel guide back end and including a front horizontal zone and a back zone including an angled or curved portion leading to a horizontal portion adjacent said front horizontal zone, and a pivotally articulated bolt train subassembly having at least one head bolt component and at least one active firing mechanism carriage component housing at least one sear lever, wherein said at least one head bolt component is situated within said at least one internal channel guide in front of said at least one active firing mechanism carriage component such that said head bolt and said active firing mechanism carriage component are consecutively and pivotally connected and disposed within said internal channel guide, wherein said head bolt component is situated within and is movable solely in a straight plane within said front horizontal zone of said internal channel guide, wherein said active firing mechanism carriage component is situated within and is movable in the plane of said front horizontal zone of said internal channel guide and in the plane of said angled or curved portion of said back zone, and wherein said firearm is selected from the group consisting of automatic and semiautomatic firearms.

2. The firearm of claim 1 wherein said articulated bolt train subassembly moves within said at least one internal channel guide in relation to activation of said trigger mechanism, wherein said bolt train moves to the foremost front of said internal channel guide prior to activation of said trigger mechanism and then moves to the rearmost back of said internal channel guide upon activation of said trigger mechanism.

3. The A method of firing the firearm of claim 1 comprising the steps of:

a) providing said firearm;

b) priming said firearm, thereby manipulating said bolt train subassembly in position with said head bolt component situated at the foremost front of said internal channel guide; and

c) activating said trigger mechanism, thereby causing said bolt train subassembly to move backward through said internal channel guide, wherein said head bolt component remains within said horizontal zone component of said internal channel guide throughout said firing of said firearm.

4. The firearm of claim 1 wherein said bolt train subassembly includes at least one recoil damper component pivotally connected to said at least one active firing mechanism carriage component and is situated closer to said back end of said internal channel guide.

5. The firearm of claim 2 wherein said bolt train subassembly includes at least one recoil damper component pivotally connected to said at least one active firing mechanism carriage component and is situated closer to said back end of said internal channel guide.

6. A method of firing the firearm of claim 2 comprising the steps of:

a) providing said firearm;

b) priming said firearm, thereby manipulating said bolt train subassembly in position with said bolt head component situated at the foremost front of said internal channel guide; and

c) activating said trigger mechanism, thereby causing said bolt train subassembly to move backward through said internal channel guide, wherein said head bolt component remains within said horizontal zone component of said internal channel guide throughout said firing of said firearm.

7. A method of firing the firearm of claim 4 comprising the steps of:

a) providing said firearm;

b) priming said firearm, thereby manipulating said bolt train subassembly in position with said bolt head component situated at the foremost front of said internal channel guide; and

c) activating said trigger mechanism, thereby causing said bolt train subassembly to move backward through said internal channel guide, wherein said head bolt component remains within said horizontal zone component of said internal channel guide throughout said firing of said firearm.

8. A method of firing the firearm of claim 5 comprising the steps of:

a) providing said firearm;

b) priming said firearm, thereby manipulating said bolt train subassembly in position with said bolt head component situated at the foremost front of said internal channel guide; and

c) activating said trigger mechanism, thereby causing said bolt train subassembly to move backward through said internal channel guide, wherein said head bolt component remains within said horizontal zone component of said internal channel guide throughout said firing of said firearm.
