ABSTRACT:
An improved friction type exercise device of the type in which a housing has an outer wall forming a hollow cavity with a central axis. A central shaft is positioned within the cavity and positioned to allow axial and rotative movement relative to the housing when moved in one axial direction and preventing axial rotative movement relative to the housing when moved in the other axial direction. A hub is positioned in the cavity and fixed to the shaft to move axially therewith while allowing rotation of the shaft relative to the hub, the hub being nonrotatable with respect to the housing and includes a first and a second opening. A rope-like member extends through the first opening in the hub, around the shaft and out the second opening in the hub whereby when the rope-like member is pulled frictional resistance is exerted on the rope-like member in proportion to the number of turns around the shaft. The rope-like member is attached to the shaft whereby with relative rotation of the shaft and the hub, the number of turns the rope-like member about the shaft is changed. A releasable mechanism for holding the shaft against rotation relative to the housing which when released allows rotation of the shaft within the cavity thereby to change the number of turns the rope-like member is wound around the shaft. A slide is positioned within the cavity and a connecting mechanism for the slide, shaft, and housing to cause movement of the slide in the direction parallel of the central axis with relative rotation between the shaft and the housing. A force gauge meter for showing a force imparted on the rope-like member and a duration of time which said force is applied to the rope-like member is operably linked to a transducer secured within the housing for measuring a force applied to the exercise device and converting the force into an electrical signal readable on the force gauge meter. A shoulder screw is used with a mounting eyelet to secure and position the central shaft.
