This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,469.

Summary of the Inventive Concept

An innovative transport device for coffins that improves operator safety, reduces fatigue, and enhances overall efficiency.

Background and Problem Solved

The original patent for a device for transporting a coffin (U.S. Pat. No. 8,918,969B2) has limitations in terms of coffin size adaptability, operator strain, and load distribution. The new inventive concept addresses these limitations by introducing adjustable sliding shelves, load-distribution mechanisms, and ergonomic handles.

Detailed Description of the Inventive Concept

The Enhanced Coffin Transport System comprises a supporting frame with adjustable sliding shelves that can be customized to fit various coffin sizes. A load-distribution mechanism is integrated to reduce operator fatigue. The system also features a quick-locking clamp with a safety hook and a mechanical interface for permanent locking or quick unlocking. An integrated ergonomic handle is designed to reduce strain on operators, and the handle is removable and adjustable to accommodate different operator preferences. Additionally, the system includes telescoping rods to increase stability and reduce the risk of coffin shifting during transport. A shock-absorbing layer on the sliding shelves reduces the impact of sudden movements on the coffin and operator.

Novelty and Inventive Step

The new inventive concept's adjustable sliding shelves, load-distribution mechanism, and ergonomic handle provide a significant improvement over the original patent. The integration of these features into a single system is novel and non-obvious, offering a substantial enhancement in coffin transport safety and efficiency.

Alternative Embodiments and Variations

Alternative embodiments of the Enhanced Coffin Transport System could include variations in the type of load-distribution mechanism, the design of the ergonomic handle, or the material used for the shock-absorbing layer. The system could also be adapted for use in different industries, such as medical or aerospace, where secure and efficient transport of sensitive or heavy loads is critical.

Potential Commercial Applications and Market

The Enhanced Coffin Transport System has significant commercial potential in the funeral industry, where it can improve operator safety and reduce fatigue. The system's adaptability and efficiency also make it suitable for use in other industries, such as medical or aerospace, where secure and efficient transport of sensitive or heavy loads is critical. The target market includes funeral homes, mortuaries, and other organizations involved in coffin transport.
