Pistol Brace With Pivotable Plates And Strap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm forearm braces fail to stabilize pistols effectively during use, interfering with proper sight alignment and providing inadequate support against muzzle drop, while also being prone to wear and potentially leading to improper shoulder-firing that violates firearms regulations.
Innovation Solution
A pistol brace with pivotable plates and a flexible strap that allows the user's forearm to position laterally, providing adjustable support and maintaining alignment with the pistol's median plane, while preventing unauthorized shoulder-firing through secure strap attachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a rigid forearm brace is used to stabilize the pistol, then stability is improved, but it interferes with proper sight alignment and causes muzzle drop
Solution Approach 1:
The patent applies the dynamics principle by making the forearm brace pivotable rather than rigid. The first and second plates can pivot independently about their respective pivot axes, allowing the brace to adapt its angle dynamically. This enables the user to adjust the brace angle to achieve proper sight alignment while maintaining stability during firing, resolving the contradiction between stability and ease of operation.
2Ease of operation
If the forearm brace is made flexible to allow movement, then ease of operation is improved, but stability during firing is reduced
Solution Approach 1:
The pivotable plates provide dynamic adjustability during setup while maintaining stability during use. The user can pivot the plates to the desired angle for proper sight alignment, and once positioned, the plates remain fixed relative to the longitudinal support, providing stable support during firing.
3Reliability
If a secure strap attachment is used to prevent shoulder-firing, then regulatory compliance is improved, but device complexity increases
Solution Approach 1:
The patent uses a flexible strap that loops through openings in the first and second plates to prevent shoulder-firing. The strap is secured to the plates using simple retention mechanisms such as tabs or friction fits, avoiding complex locking systems while still providing reliable prevention of improper shoulder-firing.

AI summary
A pistol brace for a pistol having a frame with a rear end portion and defining a median plane longitudinally through the pistol. The pistol brace has a longitudinal support configured to attach to and extend rearwardly from the pistol frame. A first plate and a second plate are pivotably attached at an upper end portion to the longitudinal support and extend down from the support in opposed alignment. The first plate and second plate can pivot independently of each other. Optionally, a flexible strap is connected to the first plate and second plate. The strap defines an adjustable passageway for the user's forearm.
