Weight Load Increase And Reduction System For Weight-Lifting Equipment

Abstract

An exercise machine including a lifting bar disposed for movement on a pivot point; a plurality of weight plate holder pegs extended from the lifting bar for securing a weight plate(s) whereby the total weight carried by the lifting bar is determined by the distance of the secured weight plate on a weight plate holder peg from the pivot point whereby the further away the weight plate(s) is from the pivot point, the heavier the weight becomes, producing multiple weight loads with only one weight plate; a pusher connected to the lifting bar which is mechanically secured by a cable fitted over a pulley to the lifting bar that the user pulls downwardly on to raise the lifting bar upwardly and raises to consequently lower the lifting bar.

What is claimed is: 
     
         1 . An exercise machine, either selectorized, plate-load, or free-weight type unit, comprising:
 a lifting bar disposed for movement on a pivot point (hinge, bolt, or similar pivoting element).   a plurality of weight plate holder pegs extended from the lifting bar for securing a weight plate(s) whereby the total weight carried by the lifting bar is determined by the distance of the secured weight plate on a weight plate holder peg from the pivot point whereby the further away the weight plate(s) is from the pivot point, the heavier the weight becomes, producing multiple weight loads with only one weight plate. The number of weight plate holder pegs can vary as well as the material of the weight plate holder pegs and the way in which they are affixed to the lifting bar.   a pusher which can be mechanically secured to the lifting bar by a cable fitted over a pulley that the user pulls downwardly on to raise the lifting bar upwardly and raises to consequently lower the lifting bar. The pusher may also be connected directly to the lifting bar.   a pivot point (hinge, bolt, or similar pivoting element) that allows the lifting bar to travel freely in an upward and downward motion.   a weight plate(s) that can be secured manually onto one of the weight plate holder pegs on the lifting bar, or by way of an adjustable weight load holder that would slide across the lifting bar instead of a series of pegs on the lifting bar, as referenced in U.S. provisional patent application Ser. No. 63/269,766, filed on Mar. 22, 2022. When the user secures the weight plate(s) to a weight plate holder peg that is further away from the pivot point, the weight load becomes heavier. When the user secures the weight plate(s) to a weight plate holder peg that is nearer to the pivot point, the weight load becomes lighter.   a pulley that allows the pusher and lifting bar to move freely.   a cable fitted over the pulley that connects the pusher to the lifting bar.
