Counter-gravity chin up and all body exercise machine

Abstract

A counter gravity exercise machine includes a frame, a seat beam for supporting a user, pivotally connected to the frame at a first pivot point on the frame, a link connected to the seat beam, wherein the link has an upper link end and a lower link end, an adjustment slider-slidingly connected to the seat beam and the link at the lower link end, wherein sliding user adjustment changes resistance via change in a mechanical advantage, a handle arm pivotally connected to the, link at a fourth pivot point and wherein the handle arm rotates and is rotably mounted on a second pivot, and an upright beam having an upper upright beam end and a lower upright beam end, wherein the lower upright beam end is connected to the frame and the upper upright beam end is connected to the second pivot point.

1 . A counter gravity exercise machine comprising: 
 a. a frame;    b. a seat beam for supporting a user, pivotally connected to the frame at a first pivot point on the frame;    c. a link connected to the seat beam, wherein the link has an upper link end and a lower link end;    d. an adjustment slider slidingly connected to the seat beam and the link at the lower link end, wherein sliding user adjustment changes resistance via change in a mechanical advantage;    e. a handle arm pivotally connected to the link at a fourth pivot point and wherein the handle arm rotates and is rotably mounted on a second pivot;    f. an upright beam having an upper upright beam end and a lower upright beam end, wherein the lower upright beam end is connected to the frame and the upper upright beam end is connected to the second pivot point.    
   
   
       2 . The counter gravity exercise machine of  claim 1 , wherein the link is composite and length adjustable.  
   
   
       3 . The counter gravity exercise machine of  claim 2 , wherein the link further comprises: a handle arm adjustment pin and adjustment holes spaced at intervals.  
   
   
       4 . The counter gravity exercise machine of  claim 1 , further comprising: a handle arm locking pin positioned to lock the handle arm in a locked state.  
   
   
       5 . The counter gravity exercise machine of  claim 2 , wherein the handle arm locking pin is mechanically locked to the upright beam.  
   
   
       6 . The counter gravity exercise machine of  claim 1 , wherein the handle arm has a forward end and a rearward end and further comprises: a cam rotably mounted on the second pivot; and a mechanical connection mechanically connecting the rearward end of the handle arm to the cam.  
   
   
       7 . The counter gravity exercise machine of  claim 6 , wherein the mechanical connection is configured as a handle arm adjustment pin that adjustably engages with the cam.  
   
   
       8 . The counter gravity exercise machine of  claim 6 , wherein the mechanical connection is configured as a handle arm adjustment pin that adjustably engages with adjustment holes formed on the cam.  
   
   
       9 . The counter gravity exercise machine of  claim 6 , wherein the link is a cable.  
   
   
       10 . The counter gravity exercise machine of  claim 6 , wherein the cam is selectively locked to the upright beam by a handle arm locking pin.  
   
   
       11 . The counter gravity exercise machine of  claim 1 , wherein the handle arm has a forward end and a rearward end and further comprises: 
 a. a cam rotably mounted on the second pivot;    b. a mechanical connection mechanically connecting the rearward end of the handle arm to the cam; and    c. a pulley mounted on a pulley arm, wherein the pulley arm rests against a pulley arm stop in a stop position but has freedom of movement toward an extended position; wherein the pulley arm stop limits movement beyond a stop position; 
 wherein the pulley arm is mounted on the second pivot; wherein the cam has a pulley arm pusher pushing the pulley arm toward an extended position when a user does exercises that extend the pulley arm and wherein the link is a cable,  
 whereby in exercises that do not extend the pulley arm, the handle arm moves independently of the pulley arm, whereby the seat beam rises in response to raising or lowering of the handle arm.  
   
   
   
       12 . The counter gravity exercise machine of  claim 11 , wherein the cam is selectively locked to the upright beam by a handle arm locking pin.  
   
   
       13 . The counter gravity exercise machine of  claim 11 , wherein the mechanical connection is configured as a handle arm adjustment pin that adjustably engages with the cam.  
   
   
       14 . The counter gravity exercise machine of  claim 11 , wherein the mechanical connection is configured as a handle arm adjustment pin that adjustably engages with adjustment holes formed on the cam.  
   
   
       15 . The counter gravity exercise machine of  claim 1   1 , wherein the stop position is at the rearward end of the handle arm so that the stop limits counterclockwise rotation of the pulley past around the 9 O'Clock position.  
   
   
       16 . The counter gravity exercise machine of  claim 11 , wherein the pulley is mounted on a pulley arm that moves in a single direction.  
   
   
       17 . The counter gravity exercise machine of  claim 11 , wherein the pulley arm reciprocates between the stop position and the extended position, wherein the extended position is higher than the stop position.  
   
   
       18 . The counter gravity exercise machine of  claim 11 , wherein the pulley arm reciprocates between the stop position and the extended position, wherein the extended position is lower than the stop position.
