Handgun Locking Device for Slide Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gun locking systems, such as those with geometric type locks and transversal bars, suffer from decreased precision and reliability after repeated firing cycles, leading to inaccurate and imprecise longitudinal translation of the slide, and are prone to stress due to sudden transitions, resulting in reduced performance and increased wear.
Innovation Solution
A gun with a locking system that utilizes a sliding guide and arched trajectory for the locking device, which maintains alignment and precision through a dual-function locking projection and rifling system, allowing for synchronized and independent movement of the barrel and slide, reducing wear and enhancing repeatability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If geometric type locks (Browning, Glock, Sig-Sauer) are used to lock the barrel to the slide, then the firing chamber can be locked during initial recoil stages, but the geometric coupling precision rapidly decreases after elevated number of firing cycles
Solution Approach 1:
The patent introduces a locking device as an intermediary component between the barrel and slide. This locking device includes a locking projection that engages with a locking seat, providing a more stable and durable coupling mechanism that maintains precision over extended firing cycles without relying solely on the geometric coupling between barrel and slide components.
Solution Approach 2:
The locking mechanism is segmented into distinct functional elements: a locking projection on the barrel, a locking seat on the slide, and a locking device that connects them. This segmentation allows each component to be optimized independently and provides multiple contact points that distribute wear and maintain coupling precision over time.
2Ease of operation
If a transversal bar is used to lock the barrel to the slide and release the slide, then the slide can be blocked and released, but the oblique abutments are subject to repeated stress and the transition between configurations is sudden and violent
Solution Approach 1:
The locking device is designed to transition dynamically from a locked configuration to a released configuration through controlled movement. The locking projection can move between engaging the locking seat and disengaging it, allowing smooth transition between locked and unlocked states without sudden violent movements, thereby reducing stress on the components.
Solution Approach 2:
The locking device incorporates design features that cushion and absorb the stress of repeated locking and releasing cycles. The geometry of the locking projection and locking seat is designed to distribute forces evenly, preventing stress concentration and reducing wear on the transversal bar and other components during rapid succession firing.
3Device complexity
If the slide longitudinal translation is guided by narrow contact areas, then the structure can be simpler, but the slide movement is extremely imprecise and not accurately repeatable for high number of cycles
Solution Approach 1:
The locking device serves as an intermediary guide system between the barrel and slide. The locking projection and locking seat provide precise geometric constraints that guide the longitudinal translation of the slide, ensuring accurate and repeatable movement without requiring complex external guide mechanisms. This intermediary coupling maintains precision while keeping the overall structure relatively simple.
4Adaptability or versatility
If tipping barrel systems are used without supplementary guide systems, then the firing chamber can be inclined or lowered during firing steps, but the barrel lacks precise guidance in relation to the gun frame
Solution Approach 1:
The locking device performs multiple functions simultaneously: it locks the barrel to the slide during firing, guides the barrel's movement relative to the gun frame, and maintains the firing chamber's inclination. By integrating these functions into a single component system, the patent achieves both adaptability in firing chamber orientation and precision in barrel guidance without requiring separate dedicated guide systems.

AI summary
The present invention relates to a gun (1) with a barrel (4) which proximally delimits a firing chamber (6), and a slide (8) translatable between a forward configuration in which it closes the firing chamber (6), and a rearward configuration in which it is distanced from the barrel (4) to open said chamber (6). The orientation of the firing chamber (6) in the forward configuration and in the rearward configuration is substantially parallel to the longitudinal axis (X). The gun (1) further comprises a locking device (10), which in the forward configuration acts so as to join the barrel (4) and the slide (8) and in the rearward configuration releases the slide (8) to enable its backward movement. The locking device (10) comprises at least one locking projection (12, 14) which, when the slide (8) and the barrel (4) are reciprocally released, guides the slide (8) in translation.
