Holster Lever Protective Screen for Debris and Unauthorized Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing firearm holster restraining systems are vulnerable to obstruction by external pressures or obstacles, and can be jammed by dust or debris, making it difficult or impossible to extract the gun during critical situations, and lack visibility of the unhooking mechanism, leading to potential safety risks.
Innovation Solution
A holster with a restraining system featuring a partially covered lever that allows operation even under external pressure or debris, with a protective screen that prevents unauthorized access and maintains visibility for the user, ensuring the lever remains functional and visible for intuitive operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a protective covering completely covers the unhooking system, then protection against unauthorized operation and debris is improved, but visibility of the unhooking lever is lost
Solution Approach 1:
The protective covering is designed with selective transparency: it is opaque in areas where unauthorized operation might occur (protecting the lever mechanism) but transparent in areas where the user needs to see and operate the lever. This local differentiation of optical properties allows simultaneous achievement of protection and visibility.
2Ease of operation
If the lever is completely exposed, then visibility and ease of operation are improved, but vulnerability to obstruction by external pressures and debris increases
Solution Approach 1:
The protective covering applies protection selectively: it covers portions of the lever that are vulnerable to obstruction by external pressures and debris, while leaving exposed the portions that need to be visible and accessible for operation. This localized protection strategy optimizes both safety and usability.
3Reliability
If a protective covering is added, then protection against debris and unauthorized access is improved, but device complexity increases
Solution Approach 1:
The protective covering is integrated with the holster body rather than being a separate, independent component. This merging of functions allows the covering to be part of the holster's structural design, reducing overall system complexity while maintaining protection benefits.

AI summary
The present invention concerns a holster for a fire-arm comprising a restraining system (X, Y) to block the arm inside the holster. The restraining system (X, Y) comprises at least a lever (X) connected to the holster in such a way as to result rotatable between a blocking position, in which at least an end (1) of said lever (X) is put in contrast of a part of the arm, blocking it in position inside the holster, and an unblocking position, in which the lever rotates in a position that allows to extract the arm. In accordance with the invention, a protective screen (50, 60) is foreseen, arranged to cover at least a part of said lever.
