Firearm Accessory Mount with Adjustable Locking Lever
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm accessory mounting systems, particularly those using Picatinny rails, face issues with dimensional variations leading to inconsistent securement, requiring excessive force that can damage levers and causing rail abrasion, and are not quick enough for rapid mounting and dismounting.
Innovation Solution
A firearm accessory mount with a sliding channel and adjustable locking mechanism that accommodates dimensional variations in Picatinny rails, utilizing a bushing, shaft, locking lever, and multiwave compression spring to ensure secure and rapid attachment without excessive force, and prevent rail abrasion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a cam or clamping part is used to secure the accessory to the rail, then the accessory can be tightly gripped, but the clamping part rubs along the side of the rail causing abrasion and burnishing
Solution Approach 1:
A Teflon®-coated bushing is introduced as an intermediary between the clamping mechanism and the Picatinny rail. The bushing's low-friction coating allows the clamping part to move smoothly without directly contacting and abrading the rail surface, thereby maintaining secure grip while preventing rail damage
Solution Approach 2:
The friction characteristics between the clamping mechanism and rail are changed by applying a Teflon® coating to the bushing. This parameter change reduces the coefficient of friction, allowing the clamping part to secure the accessory tightly without rubbing and abrading the rail surface
2Reliability
If knobs are rotated through several 360° revolutions to couple or decouple the mounting arrangement, then secure attachment is achieved, but the mounting and dismounting process is slow
Solution Approach 1:
The static rotation operation is transformed into a dynamic lever-pivoting motion. The lever pivots about a vertical axis through less than 360° (preferably less than 180°) to engage or disengage the accessory, dramatically reducing the time and effort required compared to rotating knobs through multiple revolutions
Solution Approach 2:
Instead of rotating the clamping mechanism around the rail (conventional approach), the lever pivots on a vertical axis perpendicular to the rail, inverting the motion paradigm. This allows rapid engagement and disengagement without the time-consuming rotation required by traditional knob mechanisms
3Reliability
If excessive force is applied to the lever to secure the mounting arrangement on large Picatinny rails, then secure attachment is achieved, but the lever may break
Solution Approach 1:
The Teflon®-coated bushing acts as a mediator between the lever mechanism and the rail, reducing friction and the force required to operate the lever. This allows secure attachment to be achieved without applying excessive force that could cause the lever to break
Solution Approach 2:
The friction parameter between the clamping mechanism and rail is reduced by the Teflon® coating, changing the force requirements. This parameter change allows the lever to securely attach to large Picatinnym rails without requiring excessive force that would risk lever failure

AI summary
A firearm accessory mount includes a main part with a rail receiving portion extending in a first direction that can receive a firearm mount rail, and includes a holding part with a rail engaging portion. The holding part is movable relative to the main part so that the rail engaging portion moves approximately parallel to a second direction forming an angle to the first direction. An adjusting portion positionally adjusts the rail engaging portion with respect to the main part, approximately parallel to a third direction transverse to each of the first and second directions. A manually operable member is operatively coupled to the holding part so that the holding part is moved approximately parallel to the second direction in response to movement of the member.
