Turnbuckle Device With Integrated Pivot Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing turnbuckle devices for height safety applications require separate tensioning tools for adequate tightening, which can be misplaced, leading to potential safety system integrity issues and increased weight due to exposed threaded shafts.
Innovation Solution
A turnbuckle device with an integrated, pivotally mounted handle that allows for rotation of the body to extend or retract threaded connectors, incorporating one shaft with a hollow bore to reduce length and weight, and ensuring the handle is always attached, eliminating the need for external tools and minimizing exposed components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate tensioning tools are used for turnbuckle devices, then adequate tightening can be achieved, but the tools can be misplaced and the device weight increases
Solution Approach 1:
The handle is integrated directly onto the turnbuckle body, merging the tensioning tool with the turnbuckle device itself. This eliminates the risk of misplacement and reduces the need for additional separate tools, while still providing adequate tightening capability through the integrated handle mechanism.
2Ease of operation
If threaded shafts are exposed for tensioning operation, then rotation can be performed, but the device length and weight increase
Solution Approach 1:
One threaded shaft is positioned within the hollow bore of the other threaded shaft, creating a nested configuration. This reduces the overall length and weight of the turnbuckle device while maintaining the full tensioning capability through the integrated handle that operates both shafts simultaneously.

Applied Scientific Principles
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 integrated handle allows for efficient tensioning without external tools, reducing the risk of misplacement and weight optimization by shortening the turnbuckle length while maintaining effective tensioning capabilities, enhancing safety and usability.
Implementation Method 1
each connector having a threaded shaft configured for being received in the threaded bore of one of the pair of opposing ends of the body
Implementation Method 2
the handle may be pivotally connected to the body by a pivot connection mounted in a support boss of the body
Implementation Method 3
a handle connected to the body. The handle may be movable between a stowed position and an operational position

AI summary
A turnbuckle device for tensioning a safety line includes a body having a pair of opposing ends, with each end having a threaded bore. The turnbuckle device further includes a pair of connectors, with each connector having a threaded shaft configured for being received in the threaded bore of one of the pair of opposing ends of the body. The turnbuckle device further includes a handle connected to the body. The handle is movable between a stowed position and an operational position. In the operational position, the handle is configured for facilitating rotation of the body about a longitudinal axis of the body.
