Gravity Latch with Arcuate Base for Variable Post Sizes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gate latch devices lack a versatile and secure mechanism to accommodate various fence and gate post sizes and shapes, and do not effectively prevent unauthorized opening.
Innovation Solution
A gravity latch device with a latch assembly mounted to a fence post and a keeper assembly on a gate post, featuring a pivot latch member and a striker pin system, along with a locking mechanism that allows for secure closure and easy opening, and can be adapted to different post sizes and shapes using an arcuate or concave base for secure mounting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing gate latch devices are used, then the basic latching function is provided, but they cannot accommodate various fence and gate post sizes and shapes
Solution Approach 1:
The mounting bracket is designed with a concave or arcuate base that can conform to different post shapes and sizes, allowing a single device design to universally accommodate various fence and gate posts without requiring multiple specialized mounting structures
Solution Approach 2:
The mounting bracket incorporates adjustable or flexible mounting elements that can adapt their configuration based on the specific post dimensions and shape, enabling the same device to dynamically adjust to different installation scenarios
2Reliability
If existing gate latch devices are used, then the latching mechanism is provided, but they do not effectively prevent unauthorized opening
Solution Approach 1:
The latch mechanism features a nested structure where the latch member is received within the mounting bracket, and the keeper is integrated into the post, creating multiple levels of mechanical engagement that enhance security while maintaining operational simplicity through the gravity-assisted closing action
Solution Approach 2:
The gravity latch mechanism automatically closes and latches the gate without requiring active engagement from the user, using gravitational force to drive the latch member into the keeper, thereby providing both security and ease of operation

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The device provides secure closure and easy operation by allowing the gate to be locked and unlocked with a padlock, while accommodating various post sizes and shapes without structural modifications, ensuring secure and versatile use.

AI summary
A top pull gravity latch device to selectively secure a gate in a closed position to block the opening or portal in a fence, wall or other barrier comprising a latch assembly including a latch actuator assembly, intermediate pull actuator assembly and pivotal latch member each movable between a first and second position and a keeper assembly including a striker pin to selectively engage the pivotal latch member to move the pivotal latch member from the first to second position when the keeper assembly is moved from the second to first position and back to the first position wherein the gate is securely closed when the latch actuator assembly, intermediate pull actuator assembly, pivot latch member of the latch assembly and the striker pin of the keeper assembly are all in the first position and wherein the intermediate pull actuator assembly is moved from the first to second position to move the pivotal latch member from the first to second position clearing the striker pin of the keeper assembly to be moved from the first to second position to allow the gate to be opened.
