Rifle Scope Turret Adjustable Stop Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing scope turrets lack a reliable mechanism to prevent the dial assembly from rotating in one direction while allowing adjustable stop settings, which can lead to inconsistent point of aim adjustments and lack of user control over optical adjustments.
Innovation Solution
The scope turret incorporates an adjustable stop assembly with a nut assembly and traveler mechanism, coupled through an engagement mechanism that allows the dial assembly to rotate with the nut assembly in one direction and translate relative to it in another, using a spline ring and toothed segments for precise control, and includes a locking mechanism with springs and a lever for locking and unlocking positions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the dial assembly is allowed to rotate freely in both directions, then ease of operation is improved, but reliability deteriorates due to inconsistent point of aim adjustments
Solution Approach 1:
The dial assembly incorporates a ratchet mechanism that dynamically changes the rotational freedom of the dial. In one direction (clockwise), the dial rotates freely to allow easy adjustment. In the opposite direction (counter-clockwise), the ratchet engages to prevent rotation and maintain consistent stop positions, thus resolving the contradiction between ease of operation and reliability
2Reliability
If a stop assembly is added to prevent rotation in one direction, then reliability is improved, but device complexity worsens
Solution Approach 1:
The ratchet mechanism is integrated into the existing dial assembly structure, combining the stop function with the rotational adjustment mechanism. The ratchet teeth are formed as part of the dial assembly or its mounting structure, eliminating the need for separate stop components and reducing overall device complexity while maintaining reliability
3Adaptability or versatility
If the nut assembly is selectively coupled to the dial assembly through an engagement mechanism, then adaptability is improved, but device complexity worsens
Solution Approach 1:
The engagement mechanism between the nut assembly and dial assembly is designed to be dynamically controllable. A button or actuator allows the user to selectively engage or disengage the toothed segments from the spline ring, enabling the nut assembly to either rotate with the dial assembly or remain stationary. This dynamic engagement provides adaptability for different adjustment modes while keeping the mechanism relatively simple through straightforward mechanical coupling

AI summary
A scope turret including a dial assembly that is configured to adjust point of aim optics of a scope is disclosed. The turret may include an adjustable stop assembly that prevents the dial assembly from rotating in one direction. The adjustable stop assembly may include a traveler, a nut assembly, and a bolt. The adjustable stop assembly may be internally-adjustable or externally-adjustable. The dial assembly may include an engagement mechanism. The engagement mechanism may include a button that is slidable between an engaged position and a disengaged position of the engagement mechanism. The turret may further include a locking mechanism that selectively prevents the dial assembly from rotating in any direction.
