Firearm Stock Bipod Flush Folding Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm stocks with folding bipods continue to protrude even in the folded position, making the firearm more vulnerable to snagging and compromising grip comfort.
Innovation Solution
A firearm stock design with a bipod that folds flush into the stock, featuring an elongate slot in the forend and pivotally attached legs with a latch mechanism to securely retract the bipod within the stock's contour.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the bipod is designed to fold, then the bipod can be retracted when not in use, but the bipod still protrudes from the stock and causes snagging issues
Solution Approach 1:
The bipod legs are received within a recess in the stock when folded, with the exterior contour of the stock covering the bipod legs. This nesting arrangement allows the bipod to be concealed within the stock's exterior profile, eliminating protrusions that cause snagging while maintaining the folding functionality for when the bipod is needed.
2Object-affected harmful factors
If the bipod is folded into the stock, then snagging is reduced, but the bipod may become loose or unstable
Solution Approach 1:
A spring-loaded cam latch mechanism provides dynamic locking that automatically engages when the bipod is folded into the recess. The cam surface interacts with a latch member to secure the bipod in its folded position, preventing accidental disengagement while allowing easy deployment when needed. This dynamic system maintains reliability without requiring constant manual adjustment.
3Object-affected harmful factors
If the bipod structure is made complex to achieve flush folding, then snagging is eliminated, but the device complexity increases
Solution Approach 1:
The stock is segmented into distinct functional zones: a recess area for receiving the folded bipod, an exterior contour that covers the bipod when folded, and a latch mechanism area. This segmentation allows each component to be optimized independently while working together to achieve flush folding without excessive overall complexity.
Solution Approach 2:
The bipod legs are received within a recess in the stock, with the exterior contour of the stock covering the bipod legs. This nesting arrangement conceals the bipod within the stock's exterior profile, eliminating the need for complex external housing or casing structures.
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 solution ensures the bipod is fully concealed when not in use, reducing snagging risks and enhancing grip comfort by allowing the firearm stock to maintain a clean, snag-free profile and improved handling.
Implementation Method 1
There may be a latch having a cam surface that is spring biased to protrude into the slot
Implementation Method 2
The notches may receive the cam surface when the bipod is in the folded position, thereby releasably securing the opposing end of the legs within the slot
Implementation Method 3
A bipod having a plurality of legs is pivotally attached at one end of the legs to the bottom of the forend

AI summary
The firearm stock has a body including a forend. The bottom of the forend has an elongate slot. A bipod having a plurality of legs is pivotally attached at one end of the legs to the bottom of the forend. The bipod has an unfolded position in which an opposing end of the legs extends downwards beyond the exterior contour of the forend. The bipod has a folded position in which the opposing end of the legs is received within the elongate slot with the legs substantially within the exterior contour of the forend. The opposing end of the legs may each have a notch. There may be a latch having a cam surface that is spring biased to protrude into the slot. The notches may receive the cam surface when the bipod is in the folded position, thereby releasably securing the opposing end of the legs within the slot.
