Two-Piece Toggle Bolt Anchor for Hollow Wall Load Dispersion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fixed wing toggle bolts concentrate load on two thin faces, leading to potential wall damage and limited holding capacity, especially under high loads.
Innovation Solution
A high load toggle bolt hollow wall anchor system featuring a two-piece toggle member with a load plate and cap flange, dispersing the load across a larger area to enhance holding power, including a method for installation that involves drilling, inserting, and securing the load plate and cap flange behind the wall.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional fixed wing toggle bolts are used, then the structure is simple and easy to manufacture, but the load is concentrated on two thin faces causing wall damage and limited holding capacity
Solution Approach 1:
The toggle member is divided into two separate components: the toggle bolt itself and a load dispersing adapter. This segmentation allows the adapter to distribute the load across multiple attachment points on the wall, preventing concentration of force on two thin faces while maintaining the simplicity of the original toggle bolt mechanism.
Solution Approach 2:
The load dispersing adapter acts as an intermediary component between the toggle bolt and the wall. It receives the concentrated load from the toggle bolt and redistributes it across a wider area through multiple attachment points, thereby preventing wall damage while enhancing holding capacity.
2Strength
If conventional toggle bolts concentrate load on two thin faces, then the installation process is simple, but wall damage occurs and holding capacity is limited
Solution Approach 1:
By segmenting the load path through the adapter component, the force is distributed to multiple wall attachment points rather than concentrating on two thin faces, eliminating the harmful effect of wall damage while improving holding capacity.
Solution Approach 2:
The load dispersing adapter extends the load distribution in additional spatial dimensions by creating multiple attachment points across the wall surface, transforming the concentrated two-point load into a distributed multi-point load system that prevents wall damage.
3Strength
If a load dispersing adapter is added to the toggle bolt system, then holding capacity increases and wall damage is reduced, but the device complexity increases
Solution Approach 1:
The load dispersing adapter is designed as a simple, inexpensive component that can be easily manufactured and installed. Its added complexity is minimal compared to the significant gain in holding capacity, and the adapter itself can be a simple plastic or metal piece that distributes load without requiring complex mechanisms.

AI summary
A high load toggle bolt hollow wall anchor comprises a bolt and a two piece toggle member, wherein the first piece of the two piece toggle member is an elongated member with a threaded opening for receiving the bolt, and wherein a second piece of the two piece toggle member is a load plate having i) a planar wall engaging face, ii) a wall opening engaging ridge extending from the wall engaging face, and iii) a groove in a rear of the load plate configured to receive and to hold the elongated member therein. The load plate provides a load dispersing toggle member adaptor. A method of implementation is also disclosed.
