Abstract
A bolt action firearm that cocks the firing pin upon closing the bolt and includes a cam pin for a high velocity rimfire cartridge. In one embodiment, actuating the main spring while closing the bolt, instead of while opening the bolt, provides added safety against misfiring. A safety system is provided for the trigger mechanism and a robust connecting system for the stock.
Claims17
A bolt action firearm, comprising:
- a bolt assembly including:
- a main body defining a central bore along a central axis and an elongate slot that passes through said main body;
- a cam cylinder mounted to said main body, said cam cylinder defining a spiral-shaped slot that passes through said cam cylinder;
- a handle portion coupled to said cam cylinder;
- and
- a cam pin that extends perpendicular to said central axis, through said elongate slot of said main body, and through said spiral-shaped slot of said cam cylinder,
- wherein rotation of said bolt assembly about said central axis with said handle portion causes said spiral slot of said cam cylinder to rotate about and exert an axial force that is parallel to said central axis against said cam pin, which causes a translation of said cam pin within said elongate slot of said main body.

A cock-on-close bolt action firearm, comprising:
- a bolt assembly including:
- a main body defining central bore along a central axis and an elongate slot that passes through said main body;
- a cam cylinder mounted to said main body, said cam cylinder defining a spiral-shaped slot that passes through said cam cylinder;
- a spring retainer coupled to said cam pin and slidably engaged within said central bore, said spring retainer including a cam pin that extends perpendicular to said central axis, through said elongate slot of said main body, and through said spiral-shaped slot of said cam cylinder;
- and
- a main spring disposed distal to and in contact with said spring retainer,
- wherein rotation of said bolt assembly about said central axis from an open position to a closed position causes said cam to exert a force on said cam pin in a distal direction, which causes said cam pin and said spring retainer to move in said distal direction to apply a compressive force on said main spring.
