Optical Sight Rectifier Turn Indicator with Zero Stop
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing optical sights with rectifier turn indicators have complex constructions that require transferring rotary motion to linear reciprocating motion for identification, making them cumbersome and difficult to use, especially in low-light conditions.
Innovation Solution
An optical sight with a built-in zero stop function featuring a rotatable longitudinal identification protrusion along the upper surface of the rectifier, which is coupled to a Maltese cross mechanism for easy visual and tactile identification of turn transitions, and locking bolts for setting the zero position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a rectifier turn indicator mechanism is implemented to identify turn transitions, then the user can detect transitions between first and second turns, but the construction becomes complicated requiring transfer of rotary motion to linear reciprocating motion
Solution Approach 1:
The patent replaces complex mechanical motion transfer mechanisms with a simplified indicator system that rotates directly with the rectifier control element. The indicator comprises a longitudinal identification protrusion that rotates about an axis perpendicular to its length and parallel to the rectifier rotation axis, eliminating the need for rotary-to-linear motion conversion mechanisms while maintaining clear turn transition identification through visual and tactile feedback.
2Loss of information
If a complex motion transfer mechanism is used for turn identification, then turn transitions can be identified, but the device becomes cumbersome and difficult to use in low-light conditions
Solution Approach 1:
The patent enhances local tactile quality by providing a longitudinal identification protrusion with distinct geometric features that can be easily felt and identified by touch. The protrusion's elongated shape and position on the rectifier control element allow users to detect turn transitions through tactile feedback without requiring visual confirmation, significantly improving usability in low-light conditions where visual detection would be difficult.
3Reliability
If a zero stop function is added to the rectifier, then the zero position can be set and locked, but the construction complexity increases
Solution Approach 1:
The patent merges the zero stop function with the existing rectifier control element and indicator mechanism. The zero stop is integrated as a stopping surface on the rectifier body that engages with the indicator's longitudinal protrusion when the control element is rotated to the zero position. This integration allows the zero position to be set and locked without adding separate complex locking mechanisms, maintaining simplicity while ensuring reliable zero position retention.

AI summary
An optical sight with a rectifier and device for indicating turns of the rectifier includes a longitudinal body that houses sight elements coupled to the rectifier. The rectifier includes a rotatable control element and an indicator protruding from an upper surface of the rectifier. The indicator includes a longitudinal identification protrusion rotatable about an axis that is perpendicular to its length and parallel to an axis of rotation of the control element. A coding device is associated with the longitudinal identification protrusion and is mounted on the upper surface of the rectifier above an upper surface of the longitudinal identification protrusion, wherein a rotated position of the longitudinal identification protrusion relative to the coding device provides an indication to a user of the optical sight of turning of the rectifier. A zero stop mechanism is configured with the control element of the rectifier.
