Laterally Pivoting Trigger Lever for Firearm Accuracy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current trigger mechanisms in firearms cause undesirable movement of the firearm away from the aimed direction due to the anatomical limitations of the human hand, leading to reduced shooting accuracy as the finger's force applied to the trigger cannot be fully aligned with the longitudinal axis of the firearm's trajectory.
Innovation Solution
A trigger mechanism with a pivotal part that pivots around an axis angled less than 80 degrees, preferably parallel to the firearm's trajectory axis, allowing for a swing movement that minimizes lateral force and includes a spring system and limiting means to maintain alignment and return to neutral position, reducing the impact of finger pressure on firearm deviation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the trigger is mounted as a lever or linearly in the current state of the art, then the trigger mechanism is simple and easy to manufacture, but the finger's force causes undesirable movement of the firearm away from the aimed direction, reducing shooting accuracy
Solution Approach 1:
The trigger is divided into a fixed part and a pivotal part that can rotate independently around an axis angled less than 80 degrees to the longitudinal axis. This segmentation allows the pivotal part to pivot laterally when pressed, accommodating the natural rotation of the finger while the fixed part remains stable, thereby reducing unwanted firearm movement and improving shooting accuracy without excessive complexity
Solution Approach 2:
The trigger incorporates a dynamic pivotal part that can rotate around an angled axis during operation. This dynamic element adapts to the finger's natural rotation movement, transforming the rotational finger motion into controlled trigger activation while minimizing lateral forces that would otherwise cause the firearm to move away from the aimed direction
2Manufacturing precision
If the trigger allows lateral movement to accommodate finger rotation, then shooting accuracy improves, but the trigger mechanism complexity increases
Solution Approach 1:
The trigger is divided into a fixed part and a pivotal part that can rotate independently around an axis angled less than 80 degrees to the longitudinal axis. This segmentation allows the pivotal part to pivot laterally when pressed, accommodating the natural rotation of the finger while the fixed part remains stable, thereby reducing unwanted firearm movement and improving shooting accuracy without excessive complexity
Solution Approach 2:
The pivotal part acts as an intermediary between the finger and the fixed trigger mechanism. It absorbs and accommodates the finger's natural rotation movement through its ability to pivot around an angled axis, preventing this rotation from being directly transmitted to the firearm's firing mechanism, thus improving accuracy while isolating the complexity to just the pivotal component
3Manufacturing precision
If the pivot axis is angled parallel to the trajectory axis, then the finger's force is better aligned with the firearm's trajectory, but the trigger mechanism requires more complex mounting and positioning
Solution Approach 1:
The pivot axis is angled at less than 80 degrees (preferably parallel) to the longitudinal axis of the firearm, changing the geometric parameter of the trigger mechanism. This angular parameter change allows the pivotal part to rotate in a plane that better aligns with the finger's natural pressing motion, improving force alignment with the trajectory. The mounting means are designed to accommodate this specific angle, making the manufacturing complexity manageable through precise angular positioning

Function Achieved in This Case
The solution significantly reduces the undesired movement of the firearm, enhancing shooting precision by aligning the finger's force more closely with the firearm's trajectory axis, thereby improving shooting accuracy.

AI summary
The subject of the invention is an improved trigger and trigger mechanism that compensates for an undesirable movement of the firearm from the aimed direction, when the shooter presses the trigger. The trigger (1) consists of the fixed part (11) of the trigger (1) and the pivotal part (12) of the trigger (1), whereby the fixed part (11) of the trigger (1) is lever mounted to the remaining trigger mechanism (2) or linearly mounted to it. The pivotal part (12) of the trigger (1) is pivotally mounted to the fixed part (11) of the trigger (1) through an axis (13). The axis (13) of the pivotally mounting, around which the pivotal part swings, (12) lies in a plane (P) that is defined by the longitudinal axis (A) of the trajectory of the projectile in the firearm and longitudinal axis of the handle (3) of the firearm, whereby the axis (13) of the pivotally mounting is essentially parallel to the longitudinal axis (A) of the trajectory of the projectile in the firearm or, vis-a-vis the longitudinal axis (A), is at an angle less than 80 degrees in one or the other direction. The pivotal part (12) of the trigger (1) in its neutral position, when no force of the shooter's finger is applied, essentially extends in the plane (P), but when the pressure of the shooter's finger is applied to it, it moves from its neutral position around the axis (13) of the pivotally mounting outside the plane (P) by the angle of divergence (a). The trigger (1) also optionally includes a spring element (4, 5) that holds the pivotal part (12) in the neutral position when no force of the shooter's finger is applied, irrespective of the position of the firearm, and returns the pivotal part (12) of the trigger (1) to its neutral position when the pressure of the finger on the pivotal part (12) subsides. The trigger (1) also optionally includes limiting means (6) that prevent deviation of the pivotal part (12) of the trigger (1) over the maximum possible angle of divergence (a) of the pivotal part (12) of the trigger (1).
