Assembly for securing firearms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional secure storage units for firearms often obscure them from view, making it difficult for customers to inspect merchandise while providing inadequate security, as single locks on display cabinets can be easily broken to access all firearms.
Innovation Solution
A cable assembly comprising a securing bracket with a bent plate and a cable that is inserted into the shell ejection slot of a firearm, with the cable's ends secured in notches of a firearm holder, providing a redundant locking mechanism that secures the firearm without obstructing its view.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional secure storage units (gun safes) are used to secure firearms, then security is provided, but the firearms are hidden from view requiring salesperson assistance for inspection
Solution Approach 1:
The security system is segmented into individual firearm-level securing (via cable and bracket on each firearm) rather than cabinet-level locking. This allows each firearm to be independently secured while remaining visible, resolving the contradiction between security and inspectability.
Solution Approach 2:
A cable assembly acts as an intermediary security mechanism between the firearm and the display cabinet structure. The cable with bracket provides security without requiring the firearm to be enclosed or hidden, enabling both security and customer inspection.
2Reliability
If locks are used to secure cabinet doors of display cabinets, then security is provided, but breaking a single lock allows access to all firearms
Solution Approach 1:
The security system divides the protection into multiple independent segments, with each firearm having its own cable and bracket assembly. This segmentation means that compromising one firearm's security does not affect others, eliminating the single-point-failure vulnerability of centralized locking mechanisms.
Solution Approach 2:
The cable and bracket are pre-installed on each firearm before display, creating a preliminary security measure that is already in place. This preliminary action ensures that security is inherent to each firearm rather than relying on external locking mechanisms that can be breached.
3Reliability
If a cable assembly with bracket is inserted into the shell ejection slot, then security is provided without obscuring the firearm, but the bracket structure must fit precisely into the slot
Solution Approach 1:
The bracket is designed with specific geometric parameters (acute angle between tail and front plate, aperture positioning) that allow it to conform to the shell ejection slot geometry. By carefully controlling these parameters, the bracket achieves precise fit without requiring excessive manufacturing tolerances, resolving the contradiction between security effectiveness and manufacturing feasibility.

AI summary
An assembly, including a cable and a bracket, is configured to secure a firearm having a shell ejection slot. The bracket, including a front plate and a tail, is configured for partial insertion into the shell ejection slot. The tail is disposed at an acute angle relative to the front plate and comprises a first aperture configured for insertion of the cable. A method of securing a firearm includes inserting a tail of a bracket into the shell ejection slot so that a front plate of the bracket remains outside the shell ejection slot, inserting a first end of a cable through a first aperture of the tail, and retaining the first end of the cable in a notch of a firearm holder.
