Telescopic Sight Mount With Pivoting Spindle for Linear Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing telescopic sight mounts for hunting or sporting weapons face challenges in achieving backlash-free, stress-free, and linear adjustments, particularly in elevation and lateral adjustments, due to the use of eccentric adjustments that induce bending stress and non-linear movements.
Innovation Solution
A telescopic sight mount design featuring a bracket with a front horizontal pivot bearing and a rear pivoting threaded spindle, allowing for backlash-free, stress-free, and linear height adjustments, where the pivoting threaded spindle performs an arc-shaped movement centered on the front bearing, ensuring the adjustment wheel and counter-wheel remain parallel and flush with the weapon-side adjustment plate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an elevation eccentric is used to achieve height adjustment, then the telescopic sight can be adjusted to different elevations, but the adjustment path describes a parabolic curve making it difficult to adjust and introducing bending stress
Solution Approach 1:
Instead of using a traditional elevation eccentric that moves the scope along a parabolic curve, the patent inverts the approach by using a pivoting threaded spindle that moves linearly along the weapon axis. The scope is attached to this spindle, which pivots about a horizontal axis, converting the curved adjustment path into a linear one that is easier to operate and reduces bending stress.
Solution Approach 2:
The patent introduces a pivoting threaded spindle as an intermediary component between the scope and the weapon mount. This spindle acts as a mediator that converts rotational motion into linear motion along the weapon axis, eliminating the need for direct eccentric adjustment and reducing stress on the scope mounting components.
2Manufacturing precision
If a traditional elevation adjustment mechanism is used, then height adjustment is possible, but backlash and play occur in the adjustment mechanism
Solution Approach 1:
The patent replaces traditional mechanical elevation adjustment mechanisms (which rely on eccentrics and cam profiles) with a threaded spindle system. The threading provides precise, backlash-free adjustment through the self-locking nature of threaded fasteners, eliminating play and ensuring reliable, repeatable elevation settings.
3Adaptability or versatility
If height adjustment and lateral adjustment are combined in a single mechanism, then both adjustments can be made, but tension and play occur between the two adjustment devices
Solution Approach 1:
The patent segments the adjustment mechanism into independent height adjustment and lateral adjustment components. The height adjustment is achieved through the pivoting threaded spindle moving along the weapon axis, while lateral adjustment is handled by a separate mechanism. This segmentation allows both adjustments to function independently without creating tension or play between them, maintaining overall system stability.

AI summary
Height and/or lateral adjustment of a telescopic sight mount with a bracket (14, 14a) attached to the weapon barrel (1) or to the monoblock (14a), which consists of at least a front, weapon-side projection (52) on which a front, horizontal pivot bearing (20) for the inclination adjustment of a telescopic sight-side bracket (3, 46) is formed, wherein a rear weapon-side stud bolt (28) is arranged at an axial distance from the front pivot bearing (20), on which a pivoting threaded spindle (13) supporting the rear part of the telescopic sight-side bracket (3, 46) is pivotable about a horizontal axis (19) with tilting play (53) in order to enable a backlash-free, stress-free and linear height adjustment of the telescopic sight-side, inclination-adjustable bracket.
