Modular Locking Block with Interchangeable Feed Ramp
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing locking block devices for handgun barrels are rigidly integrated with the gun barrel, requiring labor-intensive fabrication and cannot be customized to accommodate cartridges of various shapes and calibers due to a fixed feed ramp design.
Innovation Solution
A modular locking block device with a separable and releasably locked feed ramp member that can be adapted to different shapes and dimensions, allowing for customization and attachment to a standard locking block using screw threads, flanges, and pin engagement mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the locking block device is fabricated integrally with the gun barrel to achieve robustness, then the structural strength is improved, but the manufacturing complexity and labor consumption increase
Solution Approach 1:
The locking block device is divided into separate modular components: the locking block itself and interchangeable ramp members. This segmentation allows each component to be manufactured independently with standard processes, reducing overall manufacturing complexity while maintaining the structural integrity needed for robustness through precise mating surfaces and locking mechanisms.
2Ease of manufacture
If the locking block is integrated with a fixed feed ramp, then the manufacturing process is simplified, but the adaptability to various cartridge shapes and calibers is reduced
Solution Approach 1:
The feed ramp is transformed from a fixed, static component into a dynamic, interchangeable element. Multiple ramp members with different geometries can be swapped onto the locking block depending on the cartridge type being used, allowing the system to adapt its feeding characteristics to match various cartridge shapes and calibers while keeping the base locking block standardized.
Solution Approach 2:
The locking block is designed as a universal base component that can accommodate multiple types of ramp members. This multi-functionality allows a single locking block to serve various purposes by simply changing the ramp member, enabling the same core structure to work with different cartridge types without requiring multiple specialized locking blocks.
3Device complexity
If the feed ramp is made fixed and integrated, then the device structure is simplified, but the ability to customize for specific applications is lost
Solution Approach 1:
The feed ramp function is segmented from the main locking block structure, creating independent interchangeable ramp members. This segmentation maintains relative structural simplicity of the base locking block while enabling customization through the separate ramp components that can be selected or manufactured for specific application requirements.

AI summary
A locking block device (100) provided in the region of a cartridge chamber (121) of a handgun barrel (120) has a locking block (110) for releasably locking the barrel (120) to a breech prior to firing, and has a control member (111) having a control guide (112) for swinging out the barrel (120), after firing, for the purpose of separating the barrel (120) from the breech, and further has a feed ramp (140) formed in the region of a stop member (130) of the locking block (110) for feeding a cartridge, stored in a magazine of the handgun, into the cartridge chamber (121) following ejection of a fired cartridge. A modular design capable of being adapted to meet specific requirements is achieved in that the feed ramp (140) is formed on a ramp member (150) capable of being separated from the locking block (110) and releasably locked to the locking block (110).
