Rotatable Adaptor Plate for Quick Firearm Accessory Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm accessory mounting systems are time-consuming to attach and remove, and they often result in targeting errors due to the height offset of sighting accessories relative to the firearm barrel.
Innovation Solution
A rotatable, releasable adaptor plate is designed to quickly attach and detach from a firearm rail or slide, allowing for easy interchange of accessories without the need for extensive bolt removal and reinstallation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mounting schemes using bolts and adjustor plates are used, then secure attachment is achieved, but attachment and removal becomes time-consuming
Solution Approach 1:
The mounting system is divided into separate components: a mounting plate with cammed levers that can be independently operated, and the accessory being mounted. This segmentation allows for quick attachment by simply engaging the cammed levers without removing multiple bolts, while maintaining secure attachment through the camming action that locks the accessory in place.
Solution Approach 2:
The cammed levers provide dynamic attachment and release mechanisms that can be quickly actuated. The cammed lever design allows for rapid engagement and disengagement through a simple lever motion, transforming the static bolted connection into a dynamic, quickly operable system that reduces attachment time while maintaining security.
2Adaptability or versatility
If accessories are mounted offset from the barrel, then mounting flexibility is improved, but targeting precision deteriorates due to height offset errors
Solution Approach 1:
The mounting plate introduces an additional dimensional layer between the barrel and the accessory. By providing a separate mounting surface that can be positioned at different heights and angles relative to the barrel, the system allows accessories to be mounted in optimal positions for both flexibility and precision, rather than being constrained to fixed offset positions.
Solution Approach 2:
The mounting plate serves as an intermediary element between the firearm barrel and the accessory. This intermediate platform provides a stable, adjustable surface that can be precisely positioned to eliminate height offset errors, while still allowing flexible mounting of various accessories. The intermediary absorbs the positioning requirements, enabling both adaptability and precision.
3Adaptability or versatility
If multiple accessories are mounted using traditional methods, then accessory functionality is enhanced, but replacement of accessories becomes cumbersome
Solution Approach 1:
The mounting plate is pre-configured with multiple mounting positions and cammed lever mechanisms ready for quick engagement. Accessories can be pre-attached to the mounting plate, and the entire assembly can be quickly swapped between accessories by simply releasing the cammed levers. This preliminary preparation of the mounting system enables rapid field replacement without the need to remove and reinstall multiple bolts for each accessory change.

AI summary
A quick-attachment/quick-release firearm accessory mounting assembly releasably and rotatably attached to a firearm rail, chassis, or handgun slide to receive any of a number of different accessories, such as, a telescopic sight, reflector sight, laser sight, night vision sight, thermal scope, range finder, and other secondary instruments. The mounting assembly is in the form of an adaptor plate having attachment structures for receiving the accessory on a top surface, and securing to the firearm structure on a bottom surface. The firearm is modified to receive the adaptor plate, the firearm frame having a recess portion with a center protrusion in rotatable communication with a center aperture in the adaptor plate, and having grooves or slots formed at each end of the recess portion to receive flanges at each end of the adaptor plate upon rotation.
