Shotgun Sear Conversion to Release Trigger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional pull triggers in shotguns hinder the downward sweeping motion required for trap shooting, as they tend to pull the shotgun upward, necessitating a conversion to a release trigger that actuates the striking device when the trigger is released rather than pulled.
Innovation Solution
A sear configuration with a second holding surface that converts a pull trigger to a release trigger, allowing the striker catch to be held until the trigger is released, and a pressure adjustment assembly to customize the pull and release weights, enabling seamless conversion without additional modifications to the trigger assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional pull trigger is used in a shotgun, then the trigger can be pulled back to actuate the striking device, but the natural pulling motion tends to pull the end of the shotgun upwardly, countering the desired downward sweeping direction required for trap shooting
Solution Approach 1:
The patent inverts the traditional trigger actuation mechanism by converting from a pull trigger to a release trigger. Instead of pulling the trigger back to release the sear, the trigger is pulled back to engage the sear, and releasing the trigger allows the sear to move forward and actuate the striking device. This inversion eliminates the upward pull motion that interferes with trap shooting's downward sweeping motion.
2Ease of manufacture
If a pull trigger mechanism is converted to a release trigger, then the downward sweeping motion is preserved, but the sear configuration must be modified to hold the striker catch until trigger release
Solution Approach 1:
The sear is segmented into distinct functional surfaces: a first holding surface that holds the striker catch during normal operation, and a second holding surface that holds the striker catch when the trigger is pulled back. This segmentation allows the sear to perform multiple functions within a single component, enabling the conversion from pull to release trigger without adding excessive complexity.
Solution Approach 2:
The patent adds a second holding surface to the sear, creating a three-dimensional configuration that accommodates both pull and release trigger functions. The second holding surface is positioned at a different spatial location and orientation, allowing the striker catch to be held in different positions depending on trigger state, thereby enabling release trigger operation.
3Measurement precision
If a release trigger is implemented, then trap shooting accuracy is improved by allowing downward movement, but the trigger assembly requires modification to accommodate the release mechanism
Solution Approach 1:
The modified sear serves multiple functions: it holds the striker catch during normal operation, holds the striker catch when the trigger is pulled back, and releases the striker when the trigger is released. This multi-functionality reduces the need for additional separate components, making the conversion to a release trigger more practical while maintaining shooting accuracy.

AI summary
A sear for a shotgun trigger assembly is used to convert a pull trigger to a release trigger. The release trigger sear includes a second catch surface that holds the striker catch until the trigger is released. The sear having the second catch surface may be retrofit into an existing pull trigger assembly to convert the pull trigger assembly to a release trigger assembly without further modifications to the trigger assembly. The disclosure also provides a release trigger having an assembly that adjusts the pull and release weights of the trigger.
