Abstract: An endless loop rope climbing machine that maintains a constant rope speed through a hydraulic resistance mechanism. This method and device uses a climbing rope threaded about a tapered friction sheave connected to a hydraulic pump via a shaft. The user selects a desired fluid flow rate corresponding to a preferred rope climbing speed using a flow adjustment mechanism. Force exerted on the rope by the climber initiates the flow of fluid through the hydraulic system. Fluid is propelled through the system to a pressure compensated flow control (PCFC) valve in fluid communication with the hydraulic pump. A pressure compensating spool within this PCFC valve shifts in position to regulate fluid flow, returning a constant velocity of fluid to the hydraulic pump. The shaft connected to the hydraulic pump rotates at a consistent speed regardless of the force applied by the climber, thereby maintaining the steady rope climbing speed selected by the user.

Abstract: A straight back side chair has a seat cushion and a back member, and includes a low resistance loading device that is operated through a system of cords and pulleys from handgrips. The pulleys are supported on arms that are mounted to the back of the chair and which can be selectively positioned for different types of exercise.
