  • Patent number: 5971898
    Abstract: A sliding weight rack for removably holding free weights provided on a weight lifting bench. The rack is movable, via linear bearings, horizontally relative to the weight lifting bench so that a weight lifter can pull the rack and the weights above the weight lifter's chest. The gas strut provided on the rack will automatically retract the rack to its original rearward position once the weights have been removed from the rack. In its rearward position, the rack is out of the way of the weight lifter but is still easily accessible when the weight lifter is ready to replace the weights onto the rack.
