Abstract:
1. An exercise machine, comprising: a generally horizontal frame comprising first and second spaced-apart, substantially parallel frame rails; a carriage assembly mounted for longitudinal movement on said frame and having a carriage platform on an upper side thereof, at least one tension member that yieldingly biases the carriage assembly towards a foot end of said frame; a first foot platform mounted at said foot end of said frame; a second foot platform mounted at an opposite, head end of said frame; a first angularly adjustable transverse bar mounted to said frame proximate said foot end thereof; and a second angularly adjustable transverse bar mounted to said frame proximate said head end thereof; said first and second angularly adjustable transverse bars mounted to said frame each comprising: a generally horizontal transverse bar member; first and second parallel, pivotable arm members having upper ends mounted to ends of said transverse bar member and lower ends mounted to pivot axes at opposite sides of said frame, said lower ends of said arm members being radially slideable relative to said pivot axes; first and second quadrant plates mounted to said opposite sides of said frame, said quadrant plates each comprising a plurality of spaced apart indexing slots extending generally about said pivot axes and an arcuate connecting slot communicating between said indexing slots; and first and second indexing pins mounted to said lower ends of said pivotable arm members that are received in said slots of said quadrant plates; so that said transverse bar member is adjustable by sliding said arm members upwardly to raise said indexing pins out of a first pair of said indexing slots at a first angular position, pivoting said arm members to move said indexing pins through said connecting slots, and sliding said arm members downwardly to lower said indexing pins into a second pair of said indexing slots at a second angular position.
