Break Barrel Airgun Automatic Loading Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional break barrel airguns face challenges in loading pellets automatically during the cocking action, leading to increased time between shots and potential misalignment issues that cause jamming and accuracy problems, which existing solutions attempt to address with complex and costly elevator systems and user adjustment controls.
Innovation Solution
A break barrel airgun design featuring a tube fork, barrel pivot, sled mechanism, and shuttle system that automatically loads pellets by converting pivotal motion into forces to move a sled between cocking and firing positions, using a resilient barrier to overcome adhesion and maintain alignment between the barrel and projectile, and employing a magazine holder to position the bolt for precise loading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual pellet loading is used in break barrel airguns, then the structure remains simple, but the time between shots increases significantly
Solution Approach 1:
The patent implements automatic pellet loading during the cocking action by preparing the loading mechanism in advance. The pivot connection between barrel and tube fork is designed to automatically guide the pellet from the magazine into the barrel breech as the barrel is rotated during cocking, eliminating the need for manual loading and reducing time between shots without requiring complex additional mechanisms
2Productivity
If elevator systems are used to automate pellet loading, then loading speed improves, but device complexity and cost increase significantly
Solution Approach 1:
The patent extracts and eliminates the complex elevator system from conventional designs. Instead of using an elevator mechanism that requires seals, alignment adjustments, and multiple moving parts, the invention uses the existing pivot connection between the barrel and tube fork to automatically guide and load the pellet during cocking, achieving rapid loading without the complexity of elevator systems
Solution Approach 2:
The loading mechanism is designed to be self-acting during the cocking process. The pivot connection naturally guides the pellet into position as the barrel rotates, and the resilient barrier automatically engages to prevent misalignment, allowing the system to load pellets automatically without complex control mechanisms or user intervention
3Manufacturing precision
If resilient barrier with opening flap portion is used, then alignment between barrel and projectile is maintained, but device complexity increases
Solution Approach 1:
The patent uses a resilient barrier with an opening flap portion that flexes to accommodate the pellet while maintaining alignment. This flexible component naturally conforms to the pellet shape and guides it into proper alignment with the barrel bore during the cocking rotation, achieving precise alignment without requiring complex mechanical alignment mechanisms or user adjustments
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
Enables rapid and accurate automatic reloading with reduced misalignment risks, maintaining alignment and energy efficiency while minimizing weight and complexity, thus improving the rate of fire and usability.
Implementation Method 1
opening flap portion applies sufficient force against a portion of pellet to overcome any adhesion between bolt and pellet
Implementation Method 2
The receiver houses a spring into which energy is stored, a trigger for releasing the stored energy of the spring to drive a piston

AI summary
Break barrel airguns are provided with a loading system that uses the cocking action of the break barrel type airgun to load projectiles from a magazine held by a magazine holder into a shuttle system that is positioned by the magazine holder during loader and moved to a position aligned with the barrel during firing. The loading system has a resilient barrier between the magazine holder and the shuttle that reduces the risks of loading errors caused by adhesion between the bolt and a pellet.
