Title: Duane P Stark: Innovator in Exercise Equipment Technology
Introduction
Duane P Stark is a notable inventor based in Laguna Beach, California, recognized for his contributions to the field of exercise equipment technology. With a total of three patents to his name, Stark has developed innovative solutions that enhance the functionality and user experience of fitness devices.
Latest Patents
Stark's latest patents include a stationary exercise device featuring a load-controlling braking system. This device incorporates a drive wheel that utilizes both user-driven force and an automatically controlled friction brake resistance, making it a single-stage apparatus. The design allows for free-wheeling between the user-driven shaft and the drive wheel's periphery, which is braked by a friction belt. An electronic system provides automatic resistance control by receiving load information from a load cell and RPM data from a speed sensor. The friction belt's tension is adjusted by a motor-driven pulley based on signals indicating discrepancies between the load command and actual load.
Another significant patent is for an exercise apparatus designed to simulate stair-climbing. This innovative equipment addresses durability issues in the force-transmitting structure between each pedal and a one-way rotating drive shaft. Stark's design employs a pair of pulley wheels, each linked to a pair of cables, to effectively manage the rotation of the drive shaft. This mechanism reduces breakage problems by allowing each pulley wheel to rotate in response to the pedal-connected cable and a return spring.
