Rail Mount Locking Bar for Recoil-Resistant Thumb Hex Fastening
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rail attachment systems for gun accessories face issues with hardware loosening due to recoil and vibrations, and thread locking compounds fail over time, requiring tools for secure mounting.
Innovation Solution
A locking bar mechanism that prevents rotation of thumb hex fittings by using a main body with opposing sidewalls and lips, along with a retaining device, to maintain secure attachment without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If thread locking compounds are used to prevent hardware from backing out, then the tendency of hardware to loosen is reduced, but the compounds break down and fail with time and use and heat
Solution Approach 1:
The patent replaces the chemical thread locking compound system with a mechanical locking bar system. The locking bar physically prevents rotation of the thumb hex fittings through mechanical engagement with the rail, eliminating reliance on chemical compounds that degrade over time and with heat exposure.
Solution Approach 2:
The locking bar serves as an intermediary component between the thumb hex fittings and the rail system. It provides an additional mechanical layer of security that prevents hardware backout without interfering with the primary mounting function, while being resistant to the environmental factors that degrade thread locking compounds.
2Reliability
If tools are used to tighten bolts for secure mounting, then mounting security is improved, but the mounting process requires tools and becomes more complex
Solution Approach 1:
The thumb hex fittings are designed to be hand-tightenable, allowing users to securely mount accessories without requiring external tools. The locking bar then secures these hand-tightened fittings, creating a system that achieves tool-free operation while maintaining secure mounting through the combined action of the fittings and locking mechanism.

AI summary
An accessory mount system for rail of a gun or firearm includes a locking bar to mechanically prevent rotation of thumb hex fittings (e.g., nuts or bolts) of the accessory mount system. The locking bar may also include a wrench hole for use in tightening or loosening the thumb hex fittings.
