Trigger mechanism and a firearm containing the same

Abstract

A firearm and a trigger mechanism having a small trigger pull force, small trigger pull distance, and a large sear engagement is provided. The firearm and trigger mechanism of the present invention provides a safe firearm having a light and crisp trigger pull. Certain embodiments of the present invention may also provide for a firearm or trigger mechanism having a ratio of sear engagement to trigger pull distance that is greater than or equal to 1.0. Certain embodiments of the present invention may also provide for a firearm and a trigger mechanism operably connected with one or more jewel bearings.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention generally relates to a trigger mechanism and a firearm containing the same. More particularly, the present invention is directed towards a trigger mechanism and a firearm that is safe and has a lightweight and short trigger pull. [0003] 2. Description of the Prior Art [0004] Various types of firearms can be categorized according to various different characteristics of the firearms. For example, firearms arms can be classified according to the different trigger designs. [0005] Most military or competitive shooters appear to have adopted a trigger design called a two-stage trigger. A two-stage trigger is designed so that when the shooter “squeezes” the trigger (i.e. exert a force with his / her finger on a “trigger shoe”), there is an immediate and relatively large displacement of the trigger shoe (i.e. the first stage). This is followed by an abrupt and definitive stop and is referred to as a firs...

AI Technical Summary

Benefits of technology

[0015] A trigger mechanism and a firearm containing the same in accordance with the present invention overcomes the problems described above. More particularly, the present invention provides a trigger mechanism and / or a firearm that is safe, has a short and lightweight trigger pull, and has a crisp feel during discharge.

[0017] The trigger mechanism and / or the firearm in accordance with the present invention may also have a ratio of sear engagement to trigger pull distance greater than or equal to 0.5 and less than or equal to 10.0. Moreover, the trigger mechanism and / or the firearm in accordance with the present invention may further include jewel bearings to further reduce friction which aids in providing a trigger mechanism and / or a firearm that is safe, has a short and lightweight trigger pull, and has a crisp feel during discharge.

Problems solved by technology

Obtaining a lightweight trigger while maintaining safety has been difficult.

However, certain problems exist with such an approach.

The surfaces and edges of the two hardened steel components of the sear can degrade over time by wear, corrosion, and additional factors.

Therefore, accidental discharge of the firearm can suddenly occur without warning after prolonged use or storage, especially in a corrosive environment.

Even the presence of a safety mechanism may not be satisfactory.

For example, if a safety mechanism functions so as to maintain sear engagement, sear degradation can result in an accidental discharge of the firearm regardless of whether the safety mechanism is in place or not.

In addition, even if a safety mechanism of a firearm functions to obstruct the motion of the firing pin assembly independently of the sear mechanism, accidental discharge can nevertheless occur.

For example, sear degradation may cause an accidental discharge to occur as soon as the safety mechanism is disengaged.
