Timed Trigger Lock for Semiautomatic Firearm Misfire Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Dual mode triggers for semiautomatic firearms often experience misfires due to light primer strikes and unexpected trigger states during actuation and magazine changes, indicating a need for improved control mechanisms to ensure proper sequence and prevent jams.
Innovation Solution
A trigger-locking apparatus with a timed locking mechanism that ensures the carrier is seated before the hammer is actuated, using a timing lever or timed trigger lock mechanism to maintain the proper sequence of events in the trigger mechanism, preventing misfires and jams.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a dual mode trigger is used to allow firing on both pull and release, then the firearm gains increased functionality and versatility, but misfires occur due to light primer strikes and unexpected trigger states
Solution Approach 1:
The timing lever performs preliminary actions by controlling the sequence of events: it ensures the carrier is fully seated before allowing hammer actuation, and ensures the anti-hammer follow disconnect is engaged before trigger release can fire the weapon. This preliminary control of sequencing prevents the misfires associated with dual mode triggers.
Solution Approach 2:
The timing lever acts as an intermediary mechanism between the trigger system and the firing components. It mediates the trigger states by controlling when the hammer can be actuated and when the anti-hammer follow disconnect can engage, preventing unexpected trigger states that lead to misfires.
2Productivity
If the trigger mechanism allows rapid cycling between firing positions, then the productivity and rate of fire increase, but the sequence of events may become disrupted causing jams
Solution Approach 1:
The timing lever ensures that necessary preparatory actions are completed before each firing cycle: the carrier must be fully seated and the anti-hammer follow disconnect must be engaged before the trigger can release the hammer. This preliminary sequencing maintains reliability even during rapid firing.
Solution Approach 2:
The timing lever provides mechanical feedback by physically blocking trigger movement until the carrier is seated and the disconnect is engaged. This feedback mechanism ensures proper sequencing is maintained during rapid cycling, preventing jams caused by disrupted event sequences.

AI summary
Provided in various example embodiments is an apparatus, system, and method for improved control of selectable dual mode trigger systems for semiautomatic firearms, which may include a timed locking mechanism incorporated in the trigger system that ensures that the carrier is seated before the hammer is actuated, and that the anti-hammer-follow disconnect does not engage out of sequence. Such a mechanism ensures that the necessary steps occur in the proper sequence in the trigger mechanism, so that at any given time the trigger and firearm are ready for the next desired function to occur. The addition of a timed trigger lock mechanism to the trigger as disclosed herein ensures that the sequence of events in the trigger is maintained in the proper relationship, preventing misfires and jams. Such trigger locking mechanisms have applicability beyond dual-mode trigger systems, and may be applied in various forms to semiautomatic firearms generally.
