Pivotable Firearm Case Catcher for Access and Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ejected ammunition cases from firearms scatter and pose safety risks, requiring retrieval and can get stuck, necessitating a solution for efficient collection and access without disrupting firearm operation.
Innovation Solution
A firearm-mounted cartridge case catcher with a pivotable receptacle that can switch between operational and access orientations, allowing for easy collection of ejected cases and access to the firearm action without dismounting, featuring multiple fasteners for secure mounting and a detent mechanism for easy orientation changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a firearm mounted catcher is used to collect ejected cases, then case collection efficiency is improved and safety risks are reduced, but access to the firearm action becomes difficult without dismounting the catcher
Solution Approach 1:
The receptacle is made movable relative to the firearm action through a pivot connection, allowing it to switch between an operational orientation for collecting cases and an access orientation that clears the ejection port. This dynamic reconfiguration enables both efficient case collection and easy access to the action without dismounting the entire catcher device.
2Productivity
If the receptacle is positioned close to the action for effective case collection, then case collection efficiency is improved, but access to the action is blocked
Solution Approach 1:
The receptacle pivots between two primary orientations: in the operational orientation, it positions the mouth near the ejection port for efficient case collection; in the access orientation, it moves the mouth away from the ejection port to clear the path for manual access to the action. This dynamic positioning resolves the spatial conflict between collection efficiency and access ease.
3Productivity
If the catcher is permanently mounted on the firearm, then case collection is continuous, but flexibility for maintenance and cleaning is reduced
Solution Approach 1:
The pivot connection allows the receptacle to be dynamically repositioned during maintenance operations. The user can swing the receptacle out of the way to access the action for cleaning or troubleshooting, then return it to the collecting position when ready to resume firing. This maintains continuous attachment while providing operational flexibility.

AI summary
A cartridge case catcher and associated methods. The cartridge case catcher is configured to catch cartridges ejected from an action of a firearm. The cartridge case catcher includes a mount for mounting to the firearm. The cartridge case catcher includes a receptacle having a case compartment sized for carrying cases ejected from the action. A mouth of the catcher provides access to the case compartment. A pivot connection connects the receptacle to the mount. The receptacle is movable with respect to the mount about the pivot connection between an operational orientation to receive cases ejected from the firearm action and an access orientation in which the receptacle permits access to the action of the firearm.
