Semi-Automatic Air Rifle Pneumatic Cocking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current air rifles and pistols require manual operation for each shot, involving barrel breaking or cocking lever manipulation, limiting the number of shots and efficiency, especially when air pressure drops.
Innovation Solution
A semi-automatic pneumatic system where idle air from the muzzle directly hits the piston without changing direction, automatically cocking the rifle or pistol, allowing subsequent shots without additional manual effort, utilizing the power of idle air to maintain system readiness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual cocking operation is used for each shot, then the weapon can be operated with simple structure, but the shooting efficiency and number of shots are limited
Solution Approach 1:
The system uses the idle air emerging from the muzzle to automatically cock the weapon for the next shot. The piston is moved by the air flow itself without requiring external manual intervention, making the system self-servicing for the cocking operation.
Solution Approach 2:
The idle air that would normally be wasted is captured and used to move the piston, creating a continuous cycle where the exhaust air from one shot prepares the weapon for the next shot automatically.
2Duration of action of moving object
If the barrel is broken and reclosed for each shot, then the air chamber can be repressurized, but the operation time and efficiency are reduced
Solution Approach 1:
The system automatically performs the cocking operation using the idle air from the muzzle to move the piston, eliminating the need for manual barrel breaking or cocking lever manipulation between shots.
Solution Approach 2:
The air flow that exits the muzzle is continuously captured and used to drive the piston back, maintaining a continuous operational cycle without interruption for manual recocking.
3Productivity
If the cocking lever is pulled back manually for each shot, then the hammer can be positioned to strike the air cylinder, but the number of shots and operational efficiency are limited
Solution Approach 1:
The idle air from the muzzle automatically moves the piston and associated components to prepare the hammer for the next strike, eliminating manual cocking lever manipulation and increasing the number of shots possible.
Solution Approach 2:
The system maintains continuous readiness for firing by using each shot's exhaust air to automatically reset the cocking mechanism, allowing successive shots without manual intervention.
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 a greater number of shots and improved performance by automatically preparing the weapon for the next shot, reducing the need for manual cocking and maintaining functionality at lower air pressures.
Implementation Method 1
the idle air emerging from the muzzle is caused to hit, without changing its direction, the piston after the ammunition has left the barrel, thereby moving the piston in the direction of air

AI summary
This invention relates to a semi-automatic air rifle and air pistol with pneumatic system (PCP) operating in such a way that the air, which carries the ammunition in the pneumatic air rifles and air pistols, hits, without changing its direction, the piston at the instant it leaves the barrel to set said piston in motion towards the muzzle, and at the same time, the other members of the system that we have developed also start to move, thereby enabling, after each shot, the rifle and the pistol to become automatically prepared for the next shot.
