Carabiner Gate Locking Sleeves for Automatic Relocking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic locking carabiners are cumbersome to operate and prone to unintended unlocking due to complex multi-step operations and vulnerability to obstruction, failing to reliably prevent gate opening.
Innovation Solution
An automatic carabiner gate locking system featuring rotatable latching sleeves that independently rotate between locked and unlocked states, allowing intuitive two-finger disengagement and reliable automatic relocking without requiring hand repositioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a screw type locking mechanism is used, then the gate can be locked in the closed configuration, but the mechanism becomes cumbersome to operate and may accidentally become unlocked
Solution Approach 1:
The locking mechanism is divided into multiple independent latching sleeves (first latching sleeve, second latching sleeve) that can rotate independently. Each sleeve has its own latching feature that engages with corresponding features on the gate and frame, distributing the locking function across multiple segments rather than relying on a single complex screw mechanism.
Solution Approach 2:
Instead of requiring the user to actively screw a locking mechanism into place (as with conventional screw locks), the patent uses spring-loaded latching sleeves that automatically engage with the gate and frame when the gate is closed. The locking action occurs passively through spring force rather than requiring active user manipulation.
2Extent of automation
If an automatic locking mechanism with biasing system is used, then the gate automatically returns to locked state, but the mechanism becomes complex and vulnerable to obstruction
Solution Approach 1:
The latching sleeves are equipped with spring-loaded biasing systems that automatically push the sleeves into the locked position when the gate is closed. The mechanism serves itself by using the gate's closing motion to compress springs that then automatically engage the latching features, eliminating the need for complex multi-step automatic relocking sequences.
Solution Approach 2:
The first and second latching sleeves are nested concentrically within each other, with the second latching sleeve positioned inside the first latching sleeve. This nested arrangement allows both locking functions to be integrated in a compact space without requiring separate complex mechanisms for each latching action.
3Object-affected harmful factors
If a key-lock coupling between gate and frame is used, then unintended snagging is avoided, but the locking mechanism becomes more complex
Solution Approach 1:
The coupling between gate and frame is segmented into multiple discrete latching points through the first and second latching sleeves. Each sleeve provides a separate engagement point with corresponding latching features on the gate and frame, creating multiple secure contact points that prevent snagging without requiring a complex continuous coupling mechanism.

AI summary
An automatic carabiner gate locking system and method of operation. The system includes a frame, a gate, a gate biasing system, and a gate locking system. The gate locking system further includes a set of rotatable latching sleeves disposed over the gate. When the gate is in the closed state, the latching sleeves independently rotate between an unlocked state in which the gate is free to pivot and a locked state in which the gate may be prevented from pivoting with respect to the frame. The locked state further includes rotationally orienting the latching sleeves over the gate frame coupling region. The unlocked state further includes rotationally separating the latching sleeves to expose a locking recess over the gate recess, thereby allowing the gate to pivot. A second embodiment of the present invention relates to a method of automatically locking a carabiner gate.
