Firearm Sight Mount With Quick-Detach Lever and Offset Hinge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm sight mounting devices lack precision, sturdiness, and ease of operation, particularly in offsetting and quick-detaching features, which can lead to misalignment and difficulty in use with limited dexterity or in adverse conditions.
Innovation Solution
A mounting apparatus with a base having recessed grooves and pins for secure alignment and offsetting, a clamp mechanism with a lever for quick detachment, and spring-loaded detents to maintain zero alignment without manual manipulation, combined with a resilient surface for smooth operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a hinge is added to provide offsetting capability, then the versatility of the sight mount is improved, but the device complexity increases
Solution Approach 1:
The sight mount incorporates a hinge mechanism that allows the sight base to rotate between an aligned position (for precision shooting) and an offset position (for alternative sights like iron sights). This dynamic adjustment capability provides versatility while maintaining a relatively simple overall structure through controlled movement rather than complex multi-component systems.
2Ease of operation
If quick-detach features are added to allow tool-free removal, then the ease of operation is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The quick-detach mechanism utilizes spring-loaded detents that automatically engage with corresponding features on the sight base and rail assembly. This self-servicing system maintains precise alignment through the detent mechanism while allowing tool-free removal through simple manual actuation, eliminating the need for complex alignment procedures during detachment.
3Reliability
If the mount is made sturdy and precise to maintain zero alignment, then the reliability is improved, but the ease of operation with gloved hands deteriorates
Solution Approach 1:
The mount replaces complex multi-step mechanical adjustment mechanisms with simpler, more intuitive mechanical features. The hinge allows natural hand movement for offsetting, while the spring-loaded detents provide automatic alignment maintenance. This substitution of complex adjustment procedures with simpler mechanical features maintains reliability while improving operability with gloved hands.
4Ease of operation
If a camming surface and resilient surface are added to the clamp mechanism, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The camming surface incorporates a curved geometry that converts rotational motion of the lever into linear clamping motion. This curved cam surface provides smooth, controlled engagement of the clamp with the rail, improving ease of operation through natural arc-like movement while maintaining a relatively compact mechanism through efficient geometric conversion rather than complex multi-component systems.

Function Achieved in This Case
The solution provides a precise, sturdy, and easy-to-operate mounting system that maintains sight alignment and allows for offsetting without tools, ensuring reliable operation even with gloved hands or in limited dexterity conditions.
Implementation Method 1
A resilient surface is carried by the base adjacent to the lever, wherein the camming surface of the lever bears on the resilient surface

AI summary
A sight base is configured to receive and secure a sighting device and is coupled to a base by a pin running in each of the grooves and rotatable about the pins between an aligned position with the base extending between the parallel walls and the optical device aligned with the sighting axis, and a deployed position rotated away from the aligned position. A detent releasably retains the sight base in the aligned position. A clamp member is carried on the lower extent of the base, and releasably engages the rail with selectively movable to tighten and secure the clamp and base to the rail. A lever is coupled to the base and to the clamp member, and has a camming surface configured to move the movable portion of the clamp into and out of engagement with the rail in response to actuation of the lever. The camming surface of the lever bears on a resilient surface carried by the base.
