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. 11,857,822.

Summary of the Inventive Concept

An improved reciprocating transmission structure for exercise machines, providing enhanced user experience, safety, and efficiency through advanced features and components.

Background and Problem Solved

The original patent, 'Reciprocating transmission structure of exercise machine', has limitations in terms of user interface, safety, and data tracking. The new inventive concept addresses these limitations by incorporating advanced features such as a screen for parameter display and resistance adjustment, a safety mechanism for automatic stoppage, and a data storage unit for personalized exercise recommendations.

Detailed Description of the Inventive Concept

The enhanced reciprocating transmission structure consists of a first reciprocating member and a second reciprocating member, each performing a reciprocating vertical motion in a respective vertical plane parallel to the stationary frame of the exercise machine. The first reciprocating member includes a first reciprocating pivot portion pivotally connected to the frame and a first force-receiving portion connected to a resistance wheel. The second reciprocating member includes a second reciprocating pivot portion pivotally connected to the frame and a second force-receiving portion connected to a resistance wheel. A main rotating wheel drives the resistance wheel through a first belt and a second belt, and a first rotating wheel and a second rotating wheel are coaxially pivoted to the frame to rotate synchronously with the main rotating wheel. The structure also includes a screen for displaying parameters and allowing user adjustments, a safety mechanism for automatic stoppage, and a data storage unit for storing user exercise data and providing personalized recommendations.

Novelty and Inventive Step

The new inventive concept introduces novel features such as the screen, safety mechanism, and data storage unit, which are not present in the original patent. These features provide a significant improvement in user experience, safety, and efficiency, making the new concept non-obvious and innovative compared to the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include different types of resistance wheels, varying screen sizes and interfaces, and additional sensors for tracking user performance. Variations could also include different materials and designs for the reciprocating members and rotating wheels.

Potential Commercial Applications and Market

The enhanced reciprocating transmission structure has significant commercial potential in the fitness industry, particularly in the development of high-end exercise machines for commercial gyms and home use. The target market includes fitness enthusiasts, athletes, and individuals seeking advanced exercise equipment with improved user experience and safety features.
