Firearm Buttstock Actuator Mechanism for Thumb-Operated Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional adjustable buttstocks for firearms require users to remove their hands from the grip to adjust the length, disrupting accuracy and potentially compromising safety in dangerous situations.
Innovation Solution
An adjustable stock system with a lever and actuator configuration that allows the buttstock to be extended or collapsed without removing hands from the firearm, utilizing a biased lever mechanism and spring biasing to maintain the buttstock in extended positions, and an anchor system for secure attachment to the firearm.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional adjustable buttstocks are used, then the buttstock length can be adjusted, but the user must remove hands from grip and trigger, destabilizing accuracy and compromising safety
Solution Approach 1:
The actuator is designed to be operable by thumb motion while maintaining grip on the firearm, allowing the mechanism to serve itself through the natural positioning of the user's hand. The actuator lever and cam mechanism can be actuated by thumb pressure without requiring hand removal, making the adjustment process self-service compatible with maintained grip position.
Solution Approach 2:
The actuator serves as an intermediary mechanism between the user's thumb motion and the buttstock adjustment. The lever and cam system translates subtle thumb pressure into the mechanical action needed to move the buttstock between extended and collapsed positions, mediating the interaction while preserving grip stability.
2Adaptability or versatility
If traditional adjustable buttstocks are used, then the buttstock length can be adjusted, but time is lost and accuracy is destabilized during adjustment
Solution Approach 1:
The actuator mechanism is pre-positioned and spring-loaded to enable rapid transition between extended and collapsed positions. The cam and lever system is designed so that a single thumb motion can instantly trigger the adjustment, eliminating the need for manual manipulation or sequential steps, thus performing the adjustment action in advance of any potential need.
Solution Approach 2:
The buttstock adjustment mechanism transitions from a static, manual adjustment system to a dynamic, spring-assisted system that can rapidly respond to user input. The spring-loaded cam mechanism allows the buttstock to quickly move between positions in response to thumb actuation, reducing adjustment time while maintaining adaptability.
3Ease of operation
If the actuator is positioned for thumb operation, then the user can adjust without removing hand from grip, but the actuator mechanism becomes more complex
Solution Approach 1:
The actuator mechanism serves multiple functions: it provides the adjustment capability, maintains spring-loaded readiness for rapid operation, and interfaces with the existing firearm grip structure. The lever and cam system is designed to be actuated by thumb motion while integrating with the overall buttstock assembly, making the complex mechanism multi-functional rather than adding unnecessary complexity.

AI summary
An adjustable stock system for a firearm includes a buttstock configured to be slidably attached to the firearm for moving relative to the firearm between a collapsed position and at least one extended position, wherein the buttstock includes a plurality of buttstock grooves defined therein. The system also includes a lever having at least one lever tooth configured to mate with the plurality of buttstock grooves in a latched position. The lever is configured to mount to the firearm and to be moveable relative to the buttstock between the latched position where the buttstock cannot slide relative to the firearm, and an unlatched position where the buttstock is free to slide relative to the firearm, wherein the lever is biased to the latched position. The system also includes an actuator configured to move the lever between the latched position and the unlatched position.
