Sling Cam Buckle and Trigger Hook for Rapid Two-Point to One-Point Transition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current rifle slings, particularly two-point and one-point designs, are cumbersome and inefficient for quick transitions between carrying and accessing a firearm, often interfering with movement and requiring time-consuming conversions between states.
Innovation Solution
A sling system with a cam buckle and trigger snap hook mechanism that allows rapid adjustment between two-point and one-point configurations, featuring a linking member for quick circumference changes and a trigger snap hook with overlapping protrusions for secure attachment and detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a two-point sling is used, then the shooter can carry the weapon over the back with the sling draped across the torso, but the sling becomes cumbersome and interferes with movement
Solution Approach 1:
The sling is divided into two distinct attachment points (first attachment point near the rear of the weapon and second attachment point near the front), allowing independent adjustment and configuration changes. This segmentation enables the sling to transition between two-point and one-point modes by simply disconnecting one attachment point, reducing overall system complexity while maintaining carrying capability.
Solution Approach 2:
The sling incorporates quick-release mechanisms and adjustable components that allow dynamic reconfiguration between two-point and one-point configurations. The ability to rapidly switch between states enables the shooter to adapt to different tactical situations without removing the entire sling system, thereby reducing movement interference while preserving weapon carrying capability.
2Adaptability or versatility
If a one-point sling is used, then the shooter can transition to firing from the opposite shoulder, but the rifle dangles and hangs off the shooter in an inconvenient fashion
Solution Approach 1:
By providing two separate attachment points with independent quick-release mechanisms, the sling allows the shooter to selectively engage one or both points based on the shooting situation. When both points are engaged, the rifle is securely positioned; when one point is released, the shooter can quickly transition to opposite-shoulder firing while the remaining attachment point prevents excessive dangling.
Solution Approach 2:
The sling system serves multiple functions through its two-attachment-point design: it provides secure two-point carrying for stability, enables one-point configuration for rapid opposite-shoulder transitions, and allows quick conversion between states. This multi-functionality resolves the contradiction by making the same sling system adaptable to both stable carrying and flexible shooting positions.
3Adaptability or versatility
If prior art devices are used to convert between two-point and one-point sling states, then conversion is possible, but the process is very inefficient and time-consuming
Solution Approach 1:
The sling incorporates pre-positioned quick-release mechanisms and clearly marked attachment points that are ready for immediate engagement or disengagement. The attachment points are designed with features such as accessible release levers and intuitive alignment guides, allowing the shooter to convert between configurations without fumbling or complex manipulation, thereby minimizing conversion time while maintaining adaptability.
Solution Approach 2:
The quick-release mechanisms enable the shooter to rapidly disengage the second attachment point to transition from two-point to one-point configuration, or to quickly re-engage it for conversion back to two-point mode. This rushing-through capability allows conversion to occur in seconds rather than requiring time-consuming adjustment procedures, directly addressing the time loss issue while preserving configuration versatility.
4Reliability
If a two-point sling is used, then the shooter can maintain positive control of the firearm, but the sling hangs up on the shooter's gear and interferes with movement
Solution Approach 1:
The sling's ability to dynamically switch between two-point and one-point configurations allows the shooter to maintain positive firearm control when needed (two-point mode) while minimizing movement interference by transitioning to one-point mode when navigating through gear or performing dynamic movements. The quick-release mechanisms enable rapid adaptation to avoid entanglement while preserving control capability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables users to quickly and efficiently switch between sling states, minimizing movement interference and ensuring secure weapon handling, thereby improving tactical readiness.
Implementation Method 1
A cam buckle is coupled to a second part of the loop and is for adjusting a circumference of the loop. The circumference of the loop can be increased when a first force acts on a lever of the cam buckle.
Implementation Method 2
A trigger snap hook is coupled to a third part of the loop and removably couples the trigger snap hook to a second part of a weapon. The trigger snap hook is configured to be biased closed. A gate of the trigger snap hook is configured to open when a second force acts on a trigger of the trigger snap hook.

AI summary
The sling comprises at least one strap defining a loop. The loop is to be positioned over a user's first shoulder and under a user's second shoulder. A first attaching member couples a first part of the loop to a first part of a weapon. A cam buckle is coupled to a second part of the loop and is for adjusting the size of the loop when a first force acts on a lever of the cam buckle. A trigger snap hook is coupled to a third part of the loop and is for removably coupling the loop to a second part of a weapon. A gate of the trigger snap hook is configured to open when a second force acts on a trigger of the trigger snap hook. A linking member couples the trigger of the trigger snap hook to the lever of cam buckle.
