Abstract: A hand controlled regulator is connected to a resistance-providing device through a string, includes an elongated rotatable member mounted rotatably in a casing, and a sliding carriage mounted movably in the casing. The sliding carriage is connected to a connecting end of the string, and engages the rotatable member in such a manner that rotation of the rotatable member results in a linear movement of the sliding carriage in an axial direction that is parallel to a rotation axis of the rotatable member, which, in turn, results in a linear movement of the connecting end of the string in the axial direction.

Abstract: In a resistance device for providing a resisting force to an exercise apparatus, a mounting plate is mounted fixedly on the exercise apparatus, and is disposed adjacent to a flywheel mounted rotatably on an axle. An actuating rod is mounted pivotally on the mounting plate, and is rotatable about a first axis parallel to the axle. A magnetic member includes an arched arm that is disposed so as to extend along a portion of an annular magnetically permeable surface of the flywheel and that has a pivot end connected pivotally to the mounting plate, and a movable end opposite to the pivot end and mounted movably on a coupling end portion of the actuating rod. Magnetic pieces are mounted on the arched arm and are disposed between the flywheel and the arched arm. The magnetic member is rotatable about a second axis parallel to the first axis.
