Firearm Trigger Assembly Movable Pivot Axis
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In trigger assemblies for firearms, the breech movement towards the basic position is often blocked by the trigger element, leading to operational inefficiencies and potential accidental discharge when the trigger is secured.
Innovation Solution
The trigger element pivot axis is made movable relative to the trigger element, allowing the release element to shift out of the breech's movement space when the breech moves towards the basic position, preventing blocking and enabling safe operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the trigger element is fixed in position to ensure reliable catching of the breech, then the catching reliability is improved, but the breech movement is blocked when the trigger is secured
Solution Approach 1:
The trigger element is designed with dynamic positioning capability through a pivot axis that can move relative to the trigger element body. This allows the trigger element to adapt its position: remaining fixed relative to the breech during normal operation for reliable catching, and pivoting away when the breech moves in secured state to prevent blocking. The dynamic adjustment resolves the contradiction between reliable catching and operational freedom.
Solution Approach 2:
The trigger assembly is divided into separable functional components: the trigger element body and the movable pivot axis. This segmentation allows independent movement of the pivot axis relative to the trigger element, enabling the trigger element to maintain its catching function while avoiding interference with breech movement when secured. The separated components can move independently to satisfy different operational requirements.
2Ease of operation
If the trigger element remains in the rest position to allow breech movement, then the breech can move freely, but the weapon may discharge accidentally when the trigger is secured
Solution Approach 1:
The movable pivot axis enables the trigger element to dynamically adjust its position based on operational state. When the weapon is secured and the breech moves, the pivot axis allows the trigger element to pivot away from the breech path, preventing blocking while maintaining the ability to return to the rest position for safe operation. This dynamic positioning eliminates both blocking and accidental discharge risks.
Solution Approach 2:
The movable pivot axis acts as an intermediary mechanism between the trigger element and the breech. It mediates the interaction by allowing relative movement that prevents direct contact/blocking between the trigger element and breech when secured, while still enabling the trigger element to assume the rest position for safe weapon operation. This intermediary mechanism resolves the contradiction between freedom of movement and safety.
3Object-affected harmful factors
If the trigger element is positioned to block the breech when secured, then accidental discharge is prevented, but the breech movement is hindered
Solution Approach 1:
The trigger element's position is made dynamic through the movable pivot axis. Instead of being fixed in a blocking position, the trigger element can pivot away from the breech path when the weapon is secured, eliminating the blocking effect and allowing efficient breech movement. The dynamic positioning maintains safety by allowing the trigger element to return to the rest position when needed, while improving productivity during secured operation.

AI summary
The invention relates to a trigger assembly for a fire arm, comprising a lock which can be moved between a base position and a charging position, a catch which can be moved between a resting position for releasing the lock and a catch position for catching the lock, a trigger element that can be moved between a non-actuation position and an actuation position, in order to transfer the catch from the catch position thereof into the resting position thereof, a release element that can be moved relative to the trigger element, which release element can be moved between a hold position for holding the catch in the resting position thereof and a release position for releasing a movement of the catch in the catch position thereof, wherein the release element is transferred from the hold position thereof into the release position by a contact of the lock moving into the direction of the charging position with the release element, wherein the release element can be pivoted about a release element-pivoting axis that is movable relative to the trigger element such that the release element can be moved in the non-actuation position of the trigger element by means of a lock that moves in the direction of the base position from a movement space of the lock, even if the trigger is secured.
