Abstract

See full text

A lat pulldown fitness device includes a base, a magnetorheological fluid (MRF) resistance provider, a motor, a gear train, pulleys, a cable assembly, a pulldown bar and a controller. The MRF resistance provider and the motor provide a resistance functioning as a load weight of pulling down the pulldown bar. The controller controls a current input to the MRF resistance provider to change the strength of the resistance generated from the MRF resistance provider. During a workout, the resistance provided by the lat pulldown fitness device is changeable precisely, conveniently, and quickly. Unlike its conventional counterparts which require bumper plates for use as weights, the lat pulldown fitness device is not limited to weight adjustment based on unit bumper plate but features plenty choices and controllable resolution in terms of strength of training. The MRF resistance provider is more compact and lightweight than its conventional counterparts.
