Totable, spring-biased, toggle-action firearm

Abstract

A hyper velocity firearm has a downwardly-hinging toggle action. The toggle action incorporates at least one coiled torsion spring that is incorporated in at least one pivot of the toggle. A first embodiment of the firearm employs two torsion springs. A second embodiment employs a single adjustable-tension torsion spring. Tension is adjustable without disassembly of the toggle mechanism. A third embodiment employs a horizontally-oriented compressible coil spring positioned above the toggle to bias the toggle. In the pre-discharge configuration, the toggle of the present invention is about 3 degrees from a straight angle linkage, with a negative degree angle representing an over-center condition. The toggle action is compact and reduces recoil and muzzle lift when the firearm is discharged.

1 . A bolt-action firearm comprising: 
 a frame;    a butt-stock attached to a rear portion of said frame;    a hollow barrel having a firing chamber;    a bolt movable in said frame axially to and from the firing chamber of said barrel;    a coil spring mounted in a generally horizontal position within a chamber affixed to said frame;    a buffer slidable within said chamber biased against said coil spring;    a toggle comprising a pair of hingeably coupled front and rear links, a foremost end of said front link being pivotally coupled to said bolt and a rear most end of said rear link pivotally coupled to said frame and incorporating an extension lever having a rounded end which operates against said buffer to compress said coil spring when the front and rear links are toggled in a downward direction when the weapon is fired and the bolt is driven rearward.
