Spring-Loaded Stay Bolt Mounting Rail for Telescopic Sight
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mounting devices for telescopic sights on weapons require a threaded screw connection that increases the overall height of the mounting rail, introduces axial play, and necessitates manual adjustability to compensate for manufacturing inaccuracies, leading to inefficiencies and potential structural weaknesses.
Innovation Solution
A spring-loaded stay bolt is used instead of a threaded connection, allowing for axial displacement and securing against tilting within a rail-side guide part, eliminating the need for manual adjustments and reducing the overall height of the mounting rail while maintaining a consistent clamping force through a resilient connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a threaded screw connection is used for the stay bolt, then the connection can be adjusted manually to compensate for manufacturing inaccuracies, but the overall height of the mounting rail increases and axial play is introduced
Solution Approach 1:
The patent extracts and eliminates the threaded connection component from the mounting rail structure. By replacing the threaded stay bolt with a resilient stay bolt that has a bearing against the rail, the design removes the need for threads, tapped holes, and associated adjustment mechanisms, thereby reducing the overall height of the mounting rail while maintaining compensation capabilities through the resilient bearing.
Solution Approach 2:
Instead of using a threaded connection that requires screwing in and adjustment, the patent inverts the approach by using a resilient stay bolt with a bearing that provides automatic compensation for manufacturing inaccuracies through its elastic deformation capability, eliminating the need for manual thread adjustment.
2Ease of operation
If a threaded screw connection is used for the stay bolt, then manual adjustability is provided, but axial play is introduced and structural weakness occurs
Solution Approach 1:
The patent replaces the mechanical threaded screw connection system with a resilient elastic bearing system. The stay bolt with resilient bearing uses elastic deformation to provide automatic adjustment and compensation, eliminating the need for manual thread adjustment while simultaneously preventing axial play and strengthening the structural connection through continuous elastic contact.
3Strength
If a minimum axial length is provided in the receiving hole to prevent tearing and tilting, then the threaded connection is secured, but the mounting rail height must be increased
Solution Approach 1:
The patent extracts the threaded connection requirement entirely from the design. By using a resilient stay bolt with a bearing that bears against the rail surface, the design eliminates the need for deep tapped holes and minimum axial length requirements, thereby reducing the mounting rail height while maintaining prevention of tearing and tilting through the resilient bearing mechanism.
4Manufacturing precision
If fine thread adjustments are used to compensate for manufacturing tolerances, then the distance between rails can be controlled, but the device complexity increases
Solution Approach 1:
The patent implements a self-service mechanism where the resilient stay bolt with elastic bearing automatically compensates for manufacturing tolerances and controls the distance between rails through its own elastic deformation. This self-adjusting mechanism eliminates the need for complex fine thread adjustment mechanisms, scales, and manual intervention, thereby reducing device complexity while maintaining manufacturing precision.

AI summary
A mounting device for the detachable mounting of a telescopic sight on a weapon consisting of a weapon-side base rail and a telescopic sight-side mounting rail connected thereto via at least one locking element wherein at least one clamping force acting perpendicularly to the surface of the two rails can be generated by actuating the locking element resulting in a positive and non-positive connection between the two rails wherein a clamping shaft of the locking element is held rotatably in the one rail and supports at least one wedge recess which, during rotating actuation of the locking element can be brought into non-positive engagement with a recess of a stay bolt which is arranged on the opposite rail, wherein the locking element during clamping or locking between the weapon-side base rail and the mounting rail mounted positively thereon, additionally generates a displacement force acting in the axial direction (longitudinal direction) of the two rails wherein further the stay bolt is mounted in a spring-loaded manner in a rail-side guide part in an axially displaceable manner.
