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. 11,857,474.

Summary of the Inventive Concept

A family of bed systems designed for specific, narrow markets or unique operational environments, such as disaster relief, high-security needs, or extreme weather conditions, featuring tailored load transfer assemblies and adaptations for rapid deployment, secure storage, and biometric authentication.

Background and Problem Solved

The original patent disclosed a bed with a load transfer assembly having a pivot arm and a cam arm, allowing for a tailored actuator load output. However, these beds were not designed to address the specific challenges of extreme environments, such as high-wind loads, secure storage, or biometric authentication. The new inventive concept addresses these limitations by adapting the load transfer assembly and incorporating additional features to cater to these niche markets.

Detailed Description of the Inventive Concept

The inventive concept comprises a bed system with a main frame, wheel frame, support frame, and load transfer assembly having a pivot arm and a cam arm. The cam arm is stationarily connected to the main frame and movably connected to the pivot arm, featuring a cam surface adapted for use in high-wind environments or high-security settings. The bed system may further include a reinforced structure to withstand high-wind loads, a secure storage compartment integrated into the main frame for storing medical supplies or sensitive items, and a biometric authentication system controlling access to the bed system. Additionally, the load transfer assembly is designed for rapid deployment in emergency situations, enabling swift setup in disaster relief areas.

Novelty and Inventive Step

The new claims introduce novel features tailored to specific, narrow markets or unique operational environments, such as high-wind loads, secure storage, or biometric authentication. The inventive step lies in the adaptation of the load transfer assembly and the incorporation of additional features to address the challenges of these niche markets.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include beds with adjustable cam surfaces, modular storage compartments, or integrated communication systems for emergency response scenarios. Variations could also include beds designed for extreme weather conditions, such as hurricane-resistant or earthquake-resistant beds, or beds with integrated medical equipment for disaster relief or high-security environments.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in various industries, including disaster relief, healthcare, and high-security environments. The bed systems could be marketed to organizations providing disaster relief services, hospitals, and government agencies requiring high-security solutions. The potential market size is substantial, considering the growing need for specialized solutions in these areas.
