Dual Action Gravity Latch for Dual-Sided Gate Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gate latch technologies do not effectively allow for dual-sided operation without requiring holes or complex configurations, limiting user convenience and security options.
Innovation Solution
A dual action gravity latch device featuring a pivotal latch member with upper and lower extensions, and two actuator assemblies that move the latch between latched and unlatched positions using rotational and vertical movements, allowing the gate to be opened from either side without needing holes through the gate, and utilizing a spring for bias to maintain the latched position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional latch mechanism is used, then the gate can be secured, but it cannot be operated from either side without requiring holes or complex configurations
Solution Approach 1:
The latch member is divided into multiple extensions (first extension and second extension) positioned at different locations, allowing independent engagement with actuators from either side of the gate. This segmentation enables dual-sided operation without requiring complex configurations or holes through the gate.
Solution Approach 2:
The latch member is designed to serve multiple functions: it can be engaged by actuators from either side of the gate, and it provides both latching and unlatching capabilities through its multiple extensions. This multi-functionality eliminates the need for separate mechanisms for each side.
2Adaptability or versatility
If gravity is used to maintain latched position, then the latch is simple, but additional actuators are needed for dual-sided operation
Solution Approach 1:
The first and second actuators are combined into a single integrated actuator assembly that can operate from either side of the gate. The actuator assembly includes both a first actuator and a second actuator that work together through the latch member's multiple extensions, reducing the need for separate independent actuators.
Solution Approach 2:
The latch member's multiple extensions are positioned at different spatial dimensions (upper and lower portions), allowing actuators to engage from different directions. This dimensional arrangement enables dual-sided operation without requiring additional actuators beyond what is already present in the actuator assembly.
3Ease of operation
If the latch member has multiple extensions, then dual-sided operation is enabled, but the manufacturing precision requirements increase
Solution Approach 1:
Each extension of the latch member is designed with specific local characteristics suitable for its function. The first extension is positioned in the upper portion for engagement with the first actuator, while the second extension is in the lower portion for the second actuator. This localized design simplifies manufacturing by focusing precision requirements at specific locations rather than requiring uniform high precision throughout.

AI summary
A dual action gravity latch device to secure a gate in a closed position comprising a latch assembly including a pivotal latch member movable between a latched and unlatched position, a keeper assembly including a striker pin to maintain the pivotal latch member in the latched position, a first and second actuator assembly each movable between a first configuration and a second configuration disposed on opposite sides of the gate to selectively engage the pivotal latch member such that when the second actuator assembly is in the first configuration and the first actuator assembly in the second configuration the pivotal latch member is in the unlatched position to allow the gate to be opened and when the first actuator assembly is in the first configuration and the second actuator assembly is in the second configuration the pivotal latch member is in unlatched position to allow the gate to be opened.
