Revolver Loader Plunger with Resilient Spring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for loading cartridges into revolvers are not safe and efficient, lacking effective mechanisms for quick and secure insertion.
Innovation Solution
A revolver cartridge loader with a plunger and base design, featuring circumferentially spaced cartridge engaging feet and a resilient spring system, allows for safe and efficient insertion and ejection of cartridges by minimizing contact with the cartridge rim, reducing the risk of accidental discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional loading methods are used, then the loading process is simple, but safety is compromised due to potential contact with cartridge rims
Solution Approach 1:
The plunger is segmented into multiple equally spaced feet that contact cartridges at discrete points along their axes, eliminating rim contact while maintaining secure engagement. Each foot acts as an independent contact point, distributing the loading force safely along the cartridge length.
Solution Approach 2:
The cartridge engaging feet serve as intermediary elements between the plunger and cartridges, transferring loading forces through the cartridge body rather than through rim contact. This intermediary structure prevents direct rim-plunger contact that could cause accidental discharge.
2Productivity
If manual loading is performed, then device complexity is low, but loading speed and efficiency are reduced
Solution Approach 1:
The loader is pre-configured with equally spaced feet in predetermined positions that correspond to revolver cylinder chamber spacing. This preliminary arrangement allows multiple cartridges to be loaded simultaneously in a single plunger stroke, eliminating the need for repeated manual positioning operations.
Solution Approach 2:
Multiple cartridge loading operations are merged into a single plunger action. The array of feet enables simultaneous engagement and propulsion of multiple cartridges through the cylinder chambers in one motion, dramatically increasing loading productivity.
3Ease of operation
If the plunger contacts the cartridge rim for loading, then the loading mechanism is simple, but accidental discharge risk increases
Solution Approach 1:
The contact points between the plunger feet and cartridges are strategically located at specific positions along the cartridge body rather than at the rim. This local quality change ensures that force is applied to the cartridge body which does not trigger the firing mechanism, eliminating the harmful effect of rim contact.
4Reliability
If a resilient spring system is added for safety, then safety is improved, but device complexity increases
Solution Approach 1:
The resilient spring system automatically engages and disengages from the cartridge rims during the loading cycle without requiring external control mechanisms. The spring's inherent elasticity provides the necessary engagement force to secure cartridges while automatically retracting to prevent accidental firing, making the safety mechanism self-regulating.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The loader enables safe and rapid loading of cartridges by ensuring that the plunger tips contact the center of the cartridges, reducing the likelihood of accidental firing and simplifying the loading process while maintaining safety features to prevent child disassembly.
Implementation Method 1
a resilient spring extending intermediate the upper spring engaging surface of the base and the second flange
Implementation Method 2
an outwardly extending member integrally formed as a portion of the base and including a resiliently compressible upper end shaped and dimensioned to compress resiliently to pass through the second aperture into the first aperture and, after passing through the second aperture, to expand into the first aperture to prevent the upper end from again passing through the second aperture

AI summary
A revolver cartridge loader includes a plunger and a base. The plunger includes an array of circumferentially equally spaced cartridge engaging feet each including a distal end, includes a first aperture having a first diameter, and includes a second aperture operatively associated with the first aperture. The second aperture has an upper end and a lower end, and has a second diameter less than the first diameter. The base includes a plurality of circumferentially equally spaced openings each shaped and dimensioned to slidably receive a different one of the cartridge engaging feet. The base also includes an outwardly extending member integrally formed as a portion of the base. The outwardly extending member includes a resiliently compressible upper end shaped and dimensioned to compress resiliently to pass through the second aperture into the first aperture and, after passing through the second aperture, to expand into the first aperture to prevent the upper end from again passing through the second aperture.
