A-Frame Stand With Interconnecting Legs For Barricade Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing A-frame stands for barricades are cumbersome, prone to part loss, and complex to assemble, with limitations in height and stability, and often require multiple stands to achieve adequate barrier height and coverage.
Innovation Solution
An improved A-frame stand design featuring opposing legs with interconnecting means and contact points that allow for increased rigidity and flexibility, using a gap wider than the barricade beams to accommodate standard 2×4 lumber, reducing the number of stands needed and enhancing stability and ease of assembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional A-frame stands use multiple parts and complex linking systems to achieve stability and height, then the barricade can provide adequate coverage, but the device becomes cumbersome and parts are prone to loss or misplacement
Solution Approach 1:
The patent combines multiple separate components (legs, cross legs, locking mechanisms) into an integrated A-frame stand design where the opposing legs are connected by interconnecting means at the top, forming a single stable structure that eliminates the need for multiple separate parts and complex linking systems
Solution Approach 2:
The A-frame stand is designed with interconnecting means that can accommodate various barricade beam configurations and can be used in multiple barricade arrangements, reducing the need for specialized parts for different scenarios
2Reliability
If traditional A-frame stands use narrow gaps between legs to secure beams, then the beams are held firmly, but the assembly becomes complex and difficult to dismantle
Solution Approach 1:
The gap between opposing legs is designed to be larger than traditional designs, allowing barricade beams to be easily inserted and removed while maintaining secure positioning through the interconnecting means and contact points, making the structure dynamic and adaptable
3Area of stationary object
If traditional A-frame stands use multiple stands to achieve adequate height, then the barricade coverage is sufficient, but the quantity of parts increases and handling becomes difficult
Solution Approach 1:
The A-frame stand design extends vertically by incorporating interconnecting means at the top that can support additional structures or be positioned to achieve greater height coverage, reducing the need for multiple separate stands while maintaining adequate barricade coverage

AI summary
One feature provides an A-frame stand which allows the fabrication of a barricade while using less stands. The A-frame generally provides a first and second leg to provide stable support for the A-frame, as well as at least one interconnector to increase the rigidity. The interconnectors may be comprised of first and second contact points to receive barricade beams, and there may be a gap in between the opposing legs wide enough so that a barricade beam can be placed therein while allowing some pivotal movement to create the barricade.
