Revolver Speed Loader Clip with Arcuate Grasping Portions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speed loader devices for revolver-style firearms often result in cartridge protrusion and inefficient loading due to design limitations, such as flexible bodies and protruding cartridges, which can lead to misalignment and increased complexity in loading mechanisms.
Innovation Solution
A solid one-piece plasticized speed loader clip with inward projecting and arcuate grasping portions, end support tabs, and integrated clasp portions that allow the clip to be carried in a closed position, preventing cartridge slide-out and facilitating easy loading into a revolver cylinder by opening to allow cartridges to fall into individual chambers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flexible body with protruding cartridges is used, then cartridges can be easily inserted into the speed loader, but cartridge protrusion causes misalignment and inefficient loading
Solution Approach 1:
The patent changes the structural parameters of the speed loader from a flexible body with protruding cartridges to a rigid cylindrical structure where cartridges are held at precise angles. This parameter change eliminates cartridge protrusion while maintaining ease of insertion through the cylindrical design that guides cartridges into proper alignment automatically.
Solution Approach 2:
The speed loader is segmented into multiple cylindrical chambers, each designed to hold and align a specific cartridge. This segmentation allows each cartridge to be positioned independently at the correct angle, preventing misalignment while maintaining efficient loading operation.
2Reliability
If a flexible body with locking latch is used, then cartridges can be retained in the speed loader, but the loading mechanism becomes more complex
Solution Approach 1:
The patent extracts the complex locking latch mechanism from the speed loader design. Instead of using a separate locking component, the cylindrical structure itself provides retention through its geometry and the interaction between the cylinder and revolver chamber, simplifying the overall loading mechanism while maintaining reliable cartridge retention.
Solution Approach 2:
The retention function is merged into the cylindrical structure itself rather than being a separate mechanism. The cylinder's design inherently provides both cartridge holding and alignment functions, eliminating the need for additional locking components and reducing overall device complexity.
3Productivity
If cartridges are made to protrude from the speed loader body, then loading can be initiated, but misalignment and inefficient loading occur
Solution Approach 1:
The patent employs a cylindrical (curved) structure instead of a linear or flat design. This curvature allows cartridges to be positioned radially around the cylinder, with each cartridge naturally aligned at the correct angle for its respective chamber. The cylindrical geometry ensures proper alignment while maintaining rapid loading capability.

AI summary
A speed loader clip for supporting a plurality of cartridges in a cylindrical array, prior to being loaded into a plurality of individual chambers configured within a rotated open cylinder barrel of a revolver style firearm. A band of a solid one piece plasticized material includes individual pairs of inward projecting and arcuate grasping portions adapted for supporting individual ones of the cartridges. End support tabs extend between each of the pairs of projecting portions for preventing cartridge slide-out during loading into the cylinder barrel. End clasp portions are integrated into each of opposite ends of the band to permit the clip to be carried in a closed position with the supported cartridges so that, upon inserting the projecting tips of the clip supported cartridge into the barrel cylinder of the revolver, a tab located in proximity to a selected one of the inter-engaged end clasp portions is manipulated to open the band and to permit the cartridges to fall into the individual cylinder chambers.
