Barrier Gate Latching Assembly With Horizontal Trigger
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional child safety barriers often require users to apply a substantial vertical lifting force to open and close the gate, which can lead to hinge damage and misalignment of latch mechanisms due to accidental twisting or horizontal forces, compromising the gate's functionality.
Innovation Solution
The proposed solution involves an adjustable latch mechanism with retractable locking elements and a pivoting locking element, secured by a trigger mechanism, which allows for secure closure and prevents accidental opening, while also being designed to accommodate various directions of gate movement through a rotating stopper element.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional latch mechanism requiring substantial vertical lifting force is used, then the gate can be secured against accidental opening by children, but the hinges may be damaged and the latch mechanisms may become misaligned due to accidental twisting or horizontal forces
Solution Approach 1:
The latch mechanism is inverted so that the locking action occurs horizontally rather than vertically. The retractable locking elements extend horizontally to engage the latch element, and the trigger mechanism operates horizontally to release the lock, eliminating vertical lifting forces that damage hinges.
Solution Approach 2:
The latch mechanism incorporates dynamic elements including retractable locking elements that can extend and retract, a pivoting locking element that rotates to engage/disengage, and a trigger mechanism that enables easy transition between locked and unlocked states, allowing the gate to be opened without substantial force.
2Reliability
If the latch mechanism requires careful lifting to secure the upper and lower latch mechanisms, then the gate can be properly latched, but the operation becomes cumbersome and difficult to use
Solution Approach 1:
The latch mechanism is designed to be self-latching through the interaction of retractable locking elements, a pivoting locking element, and a trigger mechanism. When the gate is closed, the latch element automatically engages with the locking elements without requiring manual intervention to secure the latch, simplifying operation.
Solution Approach 2:
The triggering action is inverted from vertical lifting to horizontal pressing motion. The trigger mechanism allows the user to simply press a trigger element horizontally to release the locking elements, making the operation intuitive and easy to perform.
3Adaptability or versatility
If the latch mechanism is designed to accommodate various directions of gate movement, then the gate can be adjusted for different opening directions, but the mechanism becomes more complex
Solution Approach 1:
The latch mechanism is designed with universal functionality to accommodate multiple directions of gate movement. The rotating stopper element can be positioned to allow the gate to open in different directions, and the retractable locking elements can engage with the latch element regardless of the specific direction of movement, making the mechanism adaptable to various installation scenarios.
Solution Approach 2:
The mechanism incorporates dynamic components including a rotating stopper element that can be repositioned to control gate movement direction, and retractable locking elements that can engage dynamically as the gate moves in different directions, providing versatility without requiring multiple separate latch mechanisms.

AI summary
A barrier latch assembly having a housing including a first locking element, a second locking element, a trigger and a swing plate. The swing plate is coupled to the trigger and to the first and second locking elements. When the trigger is depressed, the swing plate pivots from an unlock position to a lock position over a rear side of the first and second locking element thereby blocking and preventing the first and second locking elements from being depressed inward.
