Abstract:
1. A cable-and-pulley device for an exercise machine having first and second user interfaces and a load, comprising: a cable having a first end coupled to the load and a second end coupled to the first user interface, the cable operatively engaging a main pulley positioned above the load, an end pulley proximate the first user interface, and a floating pulley operatively engaging the cable at a position intermediate the end pulley and the main pulley, the second user interface being operatively coupled to the floating pulley; and a tension isolator coupled to the cable at an intermediate portion of the cable between the end pulley and the main pulley; the tension isolator being adapted to engage a stop structure operatively positioned relative to the tension isolator when the cable is pulled in a first direction along a longitudinal axis of the cable, whereby a training force applied on the second user interface moves the tension isolator into contact with the stop structure, at least partially preventing subsequent motion of the cable along the first direction.
