Trailer Strap Hook Keeper Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing load securement systems for flatbed trailers face challenges in securely fastening straps to the trailer side rail, particularly in preventing the flat hook from falling out during strap tightening and ensuring effective securing of loads with tarps or ropes.
Innovation Solution
A load securement system that includes a flat hook attaching to the trailer side rail with a keeper mechanism that slides along a rail to prevent the flat hook from dislodging during strap tightening, and a C-shaped or J-shaped keeper to secure tarps or ropes, utilizing a rub rail and connector walls to protect the strap and load.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a flat hook is used to attach the strap to the side rail, then the strap can be connected to the trailer, but the flat hook may fall out of the opening during strap tightening
Solution Approach 1:
A keeper component is introduced as an intermediary element between the flat hook and the side rail opening. The keeper slides along a rail and positions itself to extend beneath the flat hook, physically preventing the hook from falling out during strap tightening operations.
Solution Approach 2:
The keeper is positioned in advance along the rail to be ready to receive and retain the flat hook. Before the strap tightening process begins, the keeper is already in place to prevent the hook from dislodging, ensuring reliable connection throughout the operation.
2Adaptability or versatility
If the keeper is designed to secure tarps or ropes, then multi-functionality is achieved, but the device complexity increases
Solution Approach 1:
The keeper is designed with a hook feature that enables it to perform multiple functions: it retains the flat hook during strap tightening and also secures tarps or ropes over the trailer load. This multi-functional design eliminates the need for separate components, achieving versatility without proportionally increasing complexity.

AI summary
A restraining strap securement system for a trailer includes a load-restraining strap with a flat hook that connects to the trailer side rail. The trailer side rail extends along the sides of the trailer and comprises a bottom wall with an opening for receiving the flat hook. A keeper slides upon a rail affixed to the bottom wall and the keeper may be positioned to extend beneath the flat hook and prevent the flat hook from falling from the opening while the strap is being tightened. The keeper may comprise a hook that can be used to secure tarps or ropes over the trailer load.
