Trigger Chock Locking Plate for Firearm Trigger Guard Blocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing trigger locks do not guarantee that a firearm cannot be discharged, as they can be manipulated or bypassed, posing a risk of unintentional or negligent discharge.
Innovation Solution
A firearm trigger chock with a chock portion and a plate that fits within the trigger guard, featuring a wedge portion for a friction fit and an aperture for a padlock, ensuring secure attachment and preventing trigger depression.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional trigger locks are used to prevent trigger manipulation, then ease of operation is improved, but reliability deteriorates because they can be manipulated or bypassed
Solution Approach 1:
The trigger chock serves as an intermediary component inserted between the trigger and trigger guard, physically blocking trigger depression. The chock portion fits into the rearward space within the trigger guard interior perimeter, creating a mechanical barrier that prevents direct contact between the trigger and the finger, thereby enhancing reliability while maintaining ease of use.
Solution Approach 2:
The trigger guard interior perimeter is segmented into distinct spatial zones: the rearward space between the trigger rear and trigger guard rear portion, and the forward space between the trigger front and trigger guard front portion. The trigger chock specifically occupies the rearward space, creating a segmented barrier that blocks trigger manipulation while allowing the rest of the trigger guard structure to remain intact.
2Reliability
If a secure locking mechanism is implemented to prevent trigger depression, then reliability is improved, but device complexity increases
Solution Approach 1:
The locking function is extracted from the trigger mechanism itself and implemented as a separate, removable trigger chock component. This external locking device can be easily attached to and removed from the trigger guard without modifying the firearm's internal mechanisms, thereby improving reliability while minimizing added complexity.
Solution Approach 2:
Instead of modifying the trigger or trigger guard to incorporate an integrated locking mechanism, the solution inverts the approach by using a separate chock component that fits into the existing trigger guard interior perimeter. This reversal simplifies the overall system by leveraging the existing trigger guard structure rather than adding complex integrated locking components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The trigger chock effectively prevents the discharge of firearms by securely locking into the trigger guard, providing a reliable barrier against accidental or intentional trigger manipulation.
Implementation Method 1
a wedge portion extending laterally, the wedge portion increasing in depth from a first point to a second point for creating a friction-type fit with the trigger guard

AI summary
A firearm trigger chock that may include a chock portion and a forward extending plate having an aperture. The chock portion is configured to prevent depression of the trigger. The chock portion has an interior side and an exterior side, and a trigger-engaging surface that substantially corresponds with the dimension and curvature of the rear of a trigger. In a version, the aperture extends through the plate and forward of the trigger.
