Firearm Support Elevation Adjustment via Threaded Knob
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional rifle stocks with angled butt stocks present challenges in maintaining elevation during firing, as existing bag riders lack adjustment mechanisms, requiring manual manipulation of sand bags or other supports to achieve desired elevation.
Innovation Solution
A firearm support system comprising a mount, rider, retainer, and rotatable knob, where the mount is coupled with the rifle stock and features a threaded longitudinal bore and enlargement, allowing for elevation adjustment through rotational motion of the knob, which translates the mount relative to the rider, enabling elevation changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional bag riders are used to support rifle stocks, then the rifle can be supported during firing, but elevation adjustment is difficult and requires manual manipulation of sand bags or other supports
Solution Approach 1:
The invention converts the static bag rider into a dynamic adjustable system by incorporating a threaded shaft and knob mechanism. The mount can slide along the rider and be secured at different positions, transforming a fixed support into an adjustable one that adapts to different elevation requirements.
Solution Approach 2:
The threaded shaft acts as an intermediary mechanism between the user's rotational input (turning the knob) and the linear motion of the mount along the rider. This mediates the adjustment process, making elevation changes precise and controlled rather than requiring manual manipulation of the entire support structure.
2Measurement precision
If manual manipulation of sand bags is used to adjust elevation, then no additional adjustment mechanisms are needed, but time is lost and precision is reduced
Solution Approach 1:
The invention replaces the manual mechanical manipulation of sand bags with a threaded fastening system. The threaded shaft converts rotational motion into precise linear positioning, providing controlled elevation adjustment that is both faster and more precise than manually shifting sand bags.
Solution Approach 2:
The threaded mechanism allows for incremental changes in elevation by rotating the knob, which moves the mount along the threaded shaft in controlled steps. This enables precise parameter adjustment of the rifle's elevation without the time loss associated with manual repositioning of support materials.
3Adaptability or versatility
If a fixed support structure is used, then the structure is simple, but adaptability to different elevation requirements is limited
Solution Approach 1:
The invention introduces dynamic adjustability to the previously static support structure. The mount's ability to slide and lock at various positions along the rider provides adaptability to different elevation requirements while maintaining structural integrity through the threaded fastening system.
Solution Approach 2:
The adjustable mount system serves multiple functions: it provides support at various elevations, accommodates different rifle stock configurations, and allows for both fine and coarse adjustments. This multi-functionality increases adaptability without proportionally increasing overall device complexity.

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 system allows for precise elevation adjustment of the rifle stock, eliminating the need for manual manipulation of supports and providing a stable, adjustable platform for improved shooting accuracy.
Implementation Method 1
The threaded shaft is configured to rotate relative to the longitudinal bore to slide the mount relative to the rider

AI summary
A firearm rest includes a mount, a rider, a retainer, a knob and a bolt. The mount has a platform configured for coupling with a firearm stock and a pedestal extending from the platform and including a threaded longitudinal bore and an enlargement distal from the platform. The rider has a front, a base and a top with a socket configured to slidingly engage the enlargement of the pedestal parallel with the longitudinal bore. The retainer is coupled with the front of the rider and has a cut-out. The knob has a groove configured for mating with the cut-out. The bolt has a first end received in the knob and a second end received in the longitudinal bore of the mount.
