Telescoping Firearm Stock With Continuous Cheek Rest
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional collapsible firearm stocks lack a sufficient range of motion in both collapsed and extended positions, affecting stability and accuracy, and often fail to provide a suitable cheek rest surface in both states.
Innovation Solution
A collapsible and extendible stock design with a mount, first and second members, and a release mechanism allowing for controlled movement along a longitudinal axis, featuring a wedge member and biasing device to adjust between fully collapsed and fully extended states, and a continuous cheek rest surface for improved aiming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the stock length in fully extended state is reduced to make it more compact, then the compactness is improved, but the stability and accuracy of the firearm deteriorates
Solution Approach 1:
The stock is divided into multiple telescoping segments (first stock segment, second stock segment, third stock segment) that can move independently relative to each other. This segmentation allows the stock to achieve a greater range of motion between fully extended and fully collapsed states, providing both compactness when needed and sufficient length for stability when required.
Solution Approach 2:
The stock incorporates a dynamic telescoping mechanism with release mechanisms that allow the stock segments to move from fixed positions to extended positions and back. This dynamic capability enables the stock to adapt its length based on operational needs, providing both compactness and stability as required by different shooting scenarios.
2Stability of the object's composition
If the stock length in fully collapsed state is increased to increase stability and accuracy, then the stability and accuracy is improved, but the firearm becomes less compact and harder to store and carry
Solution Approach 1:
The stock is divided into multiple telescoping segments (first stock segment, second stock segment, third stock segment) that can move independently relative to each other. This segmentation allows the stock to achieve a greater range of motion between fully extended and fully collapsed states, providing both compactness when needed and sufficient length for stability when required.
Solution Approach 2:
The stock segments are designed to nest within each other when collapsed, with the third stock segment fitting within the second, and the second fitting within the first. This nesting arrangement maximizes compactness in the collapsed state while maintaining the ability to extend to sufficient lengths for stability and accuracy when needed.
3Volume of moving object
If traditional collapsible stocks are designed, then the firearm can be collapsed for compactness, but the cheek rest surface is not suitable for aiming in both fully collapsed and fully extended states
Solution Approach 1:
The stock design incorporates a continuous cheek rest surface that extends across all stock segments and remains functional in both fully collapsed and fully extended states. This universal cheek rest design ensures proper cheek placement and eye alignment with the sight picture regardless of the stock's length configuration, making the stock adaptable to different shooting positions and user preferences.
Solution Approach 2:
The cheek rest surface is specifically designed with appropriate contouring and positioning on each stock segment to ensure proper fit and comfort. The local geometry of the cheek rest areas on the first, second, and third segments is optimized to maintain consistent cheek placement and sight alignment across the full range of motion, addressing the specific operational requirement for aiming comfort.

AI summary
A release mechanism assembly for a stock of a firearm may comprise a first member, a first release mechanism, and a second release mechanism. The first release mechanism and the second release mechanism may be collectively configured to selectively prevent and allow the stock to move from a fully extended state to a partially extended state, and from the partially extended state to a fully collapsed state. The first release mechanism and the second release mechanism may be each configured to move with the first member while the stock moves between the fully extended state, the partially extended state, and the fully collapsed state.
