Handgun Sight Mount Toggle Clamp for Play-Free Axial Locking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing weapon mounts for handguns lack a stable and play-free connection under axial loads, especially when mounting sighting devices or attachments, and are difficult to use in low-light conditions.
Innovation Solution
A weapon mount with a detachable mounting part featuring a toggle lever mechanism, comprising a first and second engagement element that pivot and translate relative to each other, allowing for a high clamping force with minimal stroke, and adjustable clamping force to accommodate manufacturing tolerances.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional clamping mechanism with a sliding bolt is used, then the mounting part can be detachably connected to the base part, but the connection becomes play-prone under large axial loads and requires a long clamping stroke
Solution Approach 1:
The patent transforms the static sliding bolt mechanism into a dynamic toggle lever system. The second engagement element pivots about a transverse axis, converting a linear sliding motion into a rotational pivoting motion that engages with a wedge-shaped contact area. This dynamic transformation allows the mechanism to achieve stable clamping with minimal movement stroke while maintaining reliability under axial loads.
Solution Approach 2:
The patent introduces curved pivot axes and wedge-shaped contact areas with inclined surfaces. The second engagement element pivots about a transverse axis perpendicular to the longitudinal axis, creating a rotational engagement path. The wedge-shaped geometry with inclined contact surfaces transforms the engagement motion into a self-clamping action, reducing the required clamping stroke while increasing connection stability.
2Force
If the second engagement element is pivotably arranged on the mounting body, then high clamping force is achieved with short clamping stroke, but the structure becomes more complex
Solution Approach 1:
The patent merges the second engagement element with the mounting body by pivotally connecting them to form an integrated toggle lever mechanism. This combination eliminates the need for separate complex clamping components, as the pivotable engagement element itself creates the high clamping force through its geometric configuration and pivoting action, simplifying the overall structure while maintaining high force output.
Solution Approach 2:
The patent segments the engagement system into two distinct elements: a fixed first engagement element for alignment and a pivotable second engagement element for clamping. This segmentation allows each element to perform its specific function optimally - the first element provides stable positioning while the second element delivers high clamping force through pivoting, reducing the need for overly complex single-component designs.
3Manufacturing precision
If the first engagement element has a wedge shape, then alignment along the longitudinal axis and pulling against the base part are achieved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent employs asymmetric wedge-shaped contact areas with inclined surfaces on the base part that correspond to the wedge-shaped first engagement element. This asymmetric geometry provides self-aligning features where the inclined surfaces guide the engagement element into proper alignment along the longitudinal axis during assembly. The asymmetric design compensates for minor manufacturing tolerances by providing a mechanical guidance system that automatically positions components correctly.
Solution Approach 2:
The wedge-shaped first engagement element performs preliminary alignment action before final clamping engagement. As the mounting part is brought toward the base part, the wedge-shaped element with its inclined contact surfaces automatically aligns the assembly along the longitudinal axis and pulls the parts together, preparing the system for the subsequent clamping action of the second engagement element. This preliminary alignment reduces the precision requirements for final assembly.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables precise, play-free mounting of aiming devices or attachments to handguns, even under high axial loads, with ease of installation and removal in various lighting conditions.
Implementation Method 1
The bolt is supported by a compression spring on a sliding piece pivotally connected to the toggle lever and can therefore be moved axially against the pressure of the compression spring
Implementation Method 2
The mounting body and the second engagement element pivotally connected to it form a toggle lever, by which the second engagement element is not only pivoted when folded in, but also displaced relative to the first engagement element in the direction of the longitudinal axis of the mounting body
Implementation Method 3
The first engagement element has a wedge shape adapted to a wedge-shaped contact area of a first recess in the base part, with two wedge-shaped end faces for contact with corresponding counter surfaces
