Optical Sight Locking Adjustment Assembly Zero Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical sight turrets are prone to mechanical failure over time and require external components like turret caps or depressible buttons for operation, which can lead to issues such as overtightening and binding of internal threads.
Innovation Solution
A turret assembly with a locking member and locking surface, where both are biased towards each other and adjustable about and along the rotational axis, providing a secure and adjustable locking mechanism without the need for external components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a stop mechanism is provided for stopping rotation of a turret at a zero position, then the riflescope can be reset to a zero position, but the mechanism is susceptible to failure over time
Solution Approach 1:
The patent removes the traditional stop mechanism and external turret cap components, extracting only the essential locking function. The locking member integrates the zero-position stopping function directly into the turret body without requiring separate stop mechanisms or external caps, thereby improving reliability while reducing complexity.
Solution Approach 2:
The locking member automatically engages with the locking surface at the zero position through spring biasing, providing self-service locking without requiring external caps or depressible buttons. The mechanism serves itself by using the rotational movement to automatically trigger the locking action at the predetermined zero position.
2Ease of operation
If an outer knob or cap is provided for operation, then the turret can be adjusted, but it requires external components that can lead to mechanical failure
Solution Approach 1:
The patent merges the adjustment knob function and locking function into a single integrated turret assembly. The locking member is positioned such that the same rotational movement used for adjustment automatically triggers the locking action at the zero position, eliminating the need for separate external caps or buttons and improving reliability.
3Adaptability or versatility
If the turret is over rotated, then the zero stop mechanism may be overcome, but this results in overtightening or binding of internal threads
Solution Approach 1:
The locking member is spring-biased to engage the locking surface at the zero position before any over-rotation can occur. This preliminary locking action prevents the turret from being over-rotated, thereby protecting the internal threads from overtightening or binding while still allowing full adjustment range in both directions.
4Reliability
If a locking mechanism is provided to secure zero position, then the zero position can be maintained, but it may require complex mechanisms susceptible to failure
Solution Approach 1:
The patent extracts only the essential locking function from complex traditional mechanisms. The locking member with spring biasing and locking surface provides a simple, direct locking action that secures the zero position without requiring complex linkages, multiple components, or external caps, thereby achieving high reliability with minimal complexity.

AI summary
The disclosure is directed to a locking adjustment assembly for an optical sight. The locking adjustment assembly is configured to be set at a zero locked position, adjusted from the zero locked position to a desired unlocked position and returned to the zero locked position. The locking adjustment assembly includes a biased locking member and a biased unlocking member that are configured to be adjusted about a rotational axis of the locking adjustment assembly and adjusted along the rotational axis to establish a desired zero locked position of the locking adjustment assembly.
