Thumb-Actuated Holster Lever for Secure Handgun Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional holsters for handguns lack secure retention mechanisms that are easy to actuate in stressful situations and are often complex, costly to produce, and not user-friendly for intuitive release.
Innovation Solution
A holster design featuring a polymer body with an elongate pivoting lever and a thumb-actuated mechanism that moves a trigger guard block between retention and release positions, optimized for intuitive and ergonomic release, with a U-shaped shroud for enhanced security and simplified assembly using overmolded polymers for durability and friction adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional locking mechanisms are used to securely retain the handgun, then retention security is improved, but ease of operation deteriorates due to complex actuation requirements in stressful situations
Solution Approach 1:
The release mechanism is inverted by placing the actuation button on the exterior of the holster rather than requiring internal manipulation. The button is positioned to be accessible by the user's thumb when grasping the handgun, allowing intuitive release without complex manipulation during stressful situations
Solution Approach 2:
The release function is extracted and separated from the internal retention mechanism, placing the actuation button on the exterior surface of the holster body. This allows the user to actuate the release mechanism independently of the handgun itself, simplifying the operation during drawing
2Ease of operation
If thumb buttons are exposed for easy access, then ease of operation is improved, but security deteriorates due to unintended access by others
Solution Approach 1:
The holster body includes localized guiding features such as ribs or channels that direct the user's thumb to the correct button location. These guiding structures provide intuitive access for the authorized user while preventing casual or unintended access by others who do not have the proper hand positioning
3Reliability
If multiple retention mechanisms are added to enhance security, then retention security is improved, but device complexity increases and production costs rise
Solution Approach 1:
Multiple retention functions are merged into a single integrated holster body design. The holster combines passive retention through the fitted cavity, active retention through the trigger guard engagement, and release functionality through the exterior button, all as unified components rather than separate mechanisms
Solution Approach 2:
The holster body serves multiple functions simultaneously: it provides passive retention through its fitted cavity, active retention through trigger guard engagement, and release actuation through the exterior button mechanism. This multi-functionality reduces the need for separate components

AI summary
A holster for receiving and withdrawing a handgun has a first handgun retention mechanism. The mechanism having a first lever with a tab portion for actuation and release of a trigger guard, the lever having a snap fit into a lever region without a separate pin. A belt engaging member covers the lever region capturing the first lever therein. If a second retention mechanism is used, another lever with a tab portion is positioned so the tabs are stacked, depressing one also depresses the tab behind it, such that both mechanisms are released. Accessories for the holster or belt engaging members are also provided which include a leg strap adapter that is rotatable and height-adjustable with a leg strap, a red dot sight dust cover that can be incorporated with the holster and a quick detach system that can allow for quick attachment and detachment of a holster.
