Flexible Pull System for Firearm Barrel Cleaning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm cleaning kits often require cumbersome pushing motions, making it difficult to effectively remove debris from semi-automatic and full-automatic long guns, as the cleaning elements tend to be drawn towards the action and magazine feed point, rather than away from it.
Innovation Solution
The development of a gun cleaning kit with a flexible pull system using a draw cord or cable connected to handles that allow for easy connection to cleaning jags, patches, or brushes, enabling them to be pulled through the barrel from the breech towards the muzzle, thus avoiding the action and magazine junction region.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cleaning elements are pushed through the barrel using rigid rods, then the cleaning elements can be forced into the barrel through the muzzle, but the dislodged debris and dirt are moved towards the action and magazine feed point, which is harmful
Solution Approach 1:
The patent inverts the traditional cleaning approach by pulling cleaning elements through the barrel from the breech towards the muzzle, rather than pushing them from the muzzle. This reversal of direction ensures that dislodged debris is drawn outwardly away from the action and magazine feed point, eliminating the harmful effect of debris accumulation in critical areas while maintaining effective cleaning.
2Object-affected harmful factors
If flexible cords are used to pull cleaning elements through the barrel, then debris is moved away from the action, but the handling and connection of flexible cords becomes more complex
Solution Approach 1:
The patent introduces a flexible cord as an intermediary element that connects the cleaning elements to the operator. This flexible cord serves as a mediator that transmits the pulling force from the operator's hand to the cleaning elements, enabling the beneficial pulling motion that moves debris away from the action while maintaining manageable system complexity through the use of this intermediate flexible component.
3Strength
If rigid rods are used for cleaning, then the cleaning elements can be pushed through the barrel, but the handles and actuators make it cumbersome and uncomfortable to pull cleaning jags and patches through the barrel
Solution Approach 1:
The patent replaces rigid cleaning rods with flexible cords that can be easily manipulated and pulled through the barrel. These flexible cords eliminate the cumbersome handling associated with rigid rods and their handles, while still providing sufficient strength to pull cleaning elements through the barrel and maintain the desired pulling motion that directs debris away from the action.

AI summary
Firearm cleaning kits and handles therefore optimized for pulling cleaning elements through firearm barrels away from the breach or action. Dislodged residue is displaced and removed out the muzzle. Each cleaning kit comprises one or more handles designed for axial displacements, twisting or torsional displacements, and lateral movements for pulling. Each handle comprises an elongated solid or hollow body with a bore and a slotted handle intersecting the bore. A pull cord anchor is passed through the bore, and after sliding the cable, the anchor is restrained by the follower slot either interiorly or exteriorly of the handle. A tapered front end of the handle may include a threaded socket for connection to a cleaning rod or a driving surface. The opposite handle end may include a hex drive for a variety of cleaning tools.
