Revolver Speed Loader Plunger Ejection Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing speed loaders for revolvers are cumbersome, rely on gravity for cartridge transfer, and often fail to adequately align cartridges with cylinder chambers, leading to inefficient and difficult loading processes.
Innovation Solution
A speed loader with a main body and plunger design that allows for linear ejection of cartridges without rotational movements, using elastomer materials to reduce rattling and facilitate alignment through deformable passages and plunger arms that push cartridges into revolver chambers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If cartridges are held rigidly within the loader, then alignment with chambers is maintained, but alignment difficulty increases and cartridges cannot be properly seated
Solution Approach 1:
The patent employs a flexible main body that can deform dynamically during the loading process. The loader transitions from a rigid state during insertion to a flexible state during ejection, allowing cartridges to be pushed out while maintaining alignment. This dynamic flexibility resolves the contradiction between stability and ease of operation.
Solution Approach 2:
The patent changes the physical state of the loader material from rigid to flexible by using an elastomer that can change its deformation characteristics. The elastomer's ability to deform and recover allows the loader to adapt its rigidity parameter during different phases of operation, enabling both stable positioning and easy alignment.
2Productivity
If a rotational apparatus is used to release cartridges, then cartridges can be dumped into the cylinder, but device complexity increases and operation becomes cumbersome
Solution Approach 1:
The patent extracts the rotational mechanism from the loader design and replaces it with a simple linear plunger system. By removing the complex rotational apparatus and keeping only the essential ejection function, the device achieves fast cartridge release without the burden of mechanical complexity.
Solution Approach 2:
The patent replaces the rotational mechanical system with a simpler linear mechanical system. Instead of using rotational force to dump cartridges, a plunger applies linear force directly to push cartridges out, substituting a complex rotational mechanism with a simpler linear action that achieves the same productivity goal.
3Device complexity
If gravity alone is used for cartridge transfer, then the loader structure can be simple, but cartridge ejection force is insufficient for reliable loading
Solution Approach 1:
The patent introduces a plunger as an intermediary component between the user's manual force and the cartridges. The plunger acts as a mediator that concentrates and transmits the applied force directly to the cartridges, providing sufficient ejection force without requiring a complex automated mechanism.
Solution Approach 2:
The plunger is pre-positioned within the loader to be in direct contact with the cartridges. This preliminary positioning allows the user's force to be immediately and efficiently transmitted to the cartridges during the ejection action, ensuring reliable force application without additional complex mechanisms.

AI summary
Speed loaders for loading cartridges revolver cylinders are provided. A speed loader includes a main body which is configured to accommodate a plurality of cartridges therein. The speed loader further includes a plunger movable along a longitudinal axis between a first position and a second position. Movement of the plunger from the first position to the second position causes ejection of the plurality of cartridges from the main body.
