Telescoping Safety Chain Tool for Gooseneck Trailers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators of gooseneck trailers must climb into the truck bed to hook and unhook safety chains, which is cumbersome and unsafe.
Innovation Solution
A safety chain tool with a telescoping shaft and handle allows remote operation of safety chains, enabling them to be hooked and unhooked from outside the truck bed using a coupling mechanism and actuation cable system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the operator climbs into the truck bed to hook and unhook safety chains, then the chains can be properly attached and detached, but the operator faces safety risks and operational inconvenience
Solution Approach 1:
A telescopic tool with a hook and cable mechanism serves as an intermediary device, allowing the operator to attach and detach safety chains from outside the truck bed. The tool extends through the tailgate opening, with the hook engaging the chain and cable pulling it through, eliminating the need for the operator to enter the truck bed and thus resolving the safety versus operational convenience contradiction
2Reliability
If a remote tool is used to hook and unhook safety chains, then operator safety is improved, but the device complexity increases
Solution Approach 1:
The tool is segmented into distinct functional components: a telescopic shaft for reaching through the tailgate, a hook mechanism for engaging the safety chain, and a cable system for pulling the chain through. This segmentation allows each component to perform its specific function efficiently while keeping the overall design relatively simple and manageable
Solution Approach 2:
The telescopic shaft employs a dynamic design with movable sections that can extend and retract. This dynamic feature allows the tool to adapt its length to reach the safety chains while maintaining a compact form when not in use, balancing the need for reach with the desire for simplicity and ease of storage
3Ease of operation
If the safety chain tool is left in the truck bed during transport, then easy removal of chains is enabled, but the tool occupies space in the truck bed
Solution Approach 1:
The tool features a nested design where the inner telescopic sections are contained within outer sections, and the hook mechanism can be folded or retracted into the shaft body. This nesting allows the tool to occupy minimal space in the truck bed during transport while remaining fully functional when deployed for chain attachment or removal

AI summary
The disclosed apparatus, systems and methods relate to a safety chain tool for use with gooseneck trailers. Various embodiments of the tool allow the user to remotely affix the safety chains of a gooseneck trailer, and are configured so as to be left in the bed of the truck during transport so as to allow for easy removal of the chains. In certain implementations, the tool comprises an elongate shaft with a handle at one end and a coupling mechanism at the other, wherein the coupling mechanism is fixedly attached to a chain and a clasp. In certain embodiments, the shaft contains a operational mechanism configured to actuate the clasp. In certain embodiments, this actuation is achieved by extending the ends of the shaft relative to one another.
