Silencer Mounting Rail With Trigger Guard Support Against Vibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing silencer attachments on handguns vibrate independently of the barrel, causing misalignment and preventing subsequent shots, especially in semi-automatic or fully automatic firearms.
Innovation Solution
A fastening device with a mounting rail that includes a support surface resting on the trigger guard and an axial projection to maintain contact, preventing the silencer from oscillating by absorbing forces and ensuring coaxial alignment with the barrel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the silencer is attached to the mounting rail of the handgun, then the silencer can be attached to the weapon independently of the barrel, but the silencer vibrates independently of the barrel when a shot is fired
Solution Approach 1:
The invention adds a new contact dimension by introducing a support surface that contacts the trigger guard. This creates an additional constraint plane perpendicular to the original mounting rail contact, effectively suppressing vibrations in horizontal directions while maintaining the independent attachment capability.
Solution Approach 2:
The trigger guard serves as an intermediary element between the silencer's mounting rail and the handgun's barrel assembly. By contacting the trigger guard, the mounting rail indirectly connects to the firearm's structural framework, providing vibration damping without interfering with barrel-silencer coaxial alignment.
2Device complexity
If the silencer is attached using only the mounting rail, then the structure is simple, but the support surface may lose contact with the trigger guard when a shot is fired due to gas pressure
Solution Approach 1:
The invention applies local quality enhancement by adding geometric features (protrusions and corresponding recesses) at specific locations on the mounting rail. These localized structural modifications create positive mechanical interlocking with the trigger guard, ensuring reliable contact under gas pressure without complicating the overall mounting structure.
Solution Approach 2:
The protrusions and recesses are pre-configured to counteract the downward force generated by gas pressure during firing. The geometric interlocking features are designed in advance to prevent the support surface from losing contact with the trigger guard, maintaining coaxial alignment throughout the firing cycle.
3Ease of manufacture
If the grip is made of plastic such as polyamide, then the weapon can be manufactured with modern materials, but the silencer tilts downwards when a shot is fired due to differential thermal expansion
Solution Approach 1:
The invention addresses thermal expansion parameter changes by creating a mechanical constraint system that compensates for dimensional changes. The protrusion-recess interlocking features maintain constant geometric relationships between the silencer and trigger guard, preventing tilt caused by differential expansion between plastic grip materials and metal silencer components.

AI summary
A mounting device for attaching a silencer to a firearm, in particular a handgun, is provided. The mounting device has a mounting rail, wherein a support surface is formed at the rear end of the mounting rail and wherein a projection is arranged below the support surface, the projection having a contact surface that corresponds at least partially to an underside of the trigger guard and/or to a transition section between the front face of the trigger guard and the underside of the trigger guard.
