Stretching Exercise Apparatus

Abstract

A stretching exercise apparatus includes a first leg frame, a second leg frame oppositely spaced apart from the first leg frame, a seat frame connected transversely to the first and second leg frames, a leg lift frame pivoted to the first leg frame, an upright bar extending upwardly from and connected foldably to a top end of the first leg frame, and an elastic cord unit extending through the upright bar and the first leg frame and having one end connected to the leg lift frame and another end extending outwardly of the upright bar.

What is claimed is: 
     
         1 . A stretching exercise apparatus comprising:
 a bench unit including a first leg frame, a second leg frame oppositely spaced apart from said first leg frame, a seat frame connected transversely to said first and second leg frames, and a leg lift frame pivoted to said first leg frame;   an upright bar extending upwardly from and connected foldably to a top end of said first leg frame; and   an elastic cord unit extending through said upright bar and said first leg frame and having one end connected to said leg lift frame and another end extending outwardly of said upright bar.   
     
     
         2 . The stretching exercise apparatus as claimed in  claim 1 , wherein said first leg frame includes a first leg, said seat frame including two spaced-apart seat bars connected respectively to two opposite lateral sides of said first leg, and a pivot member connected to one ends of said seat bars that are distal from said first leg, said seat frame further including a seat cushion supported on said seat bars and pivoted to said pivot member to be turnable upward relative to said seat bars, said upright bar being pivotal downward relative to said first leg frame to be disposed between said seat bars when said seat cushion is turned and lifted upward. 
     
     
         3 . The stretching exercise apparatus as claimed in  claim 2 , wherein said seat frame further includes two connecting seats disposed respectively on the other ends of said seat bars, said upright bar including a connecting piece pivoted to said connecting seats. 
     
     
         4 . The stretching exercise apparatus as claimed in  claim 2 , wherein said leg lift frame includes a movable bar having an upper end pivoted to said first leg frame and a lower end opposite to said upper end, and a hook disposed on said lower end and facing said first leg, said elastic cord unit including an elastic cord and two pull rings, said elastic cord being folded in half to form a folded end at said one end of said elastic cord unit and fixed to said hook, and two connecting ends at said another end of said elastic cord unit, said pull rings being respectively connected to said connecting ends and being disposed externally of said upright bar. 
     
     
         5 . The stretching exercise apparatus as claimed in  claim 4 , wherein said first leg frame further includes two fixing plates respectively disposed on said lateral sides of said first leg opposite to said seat bars, and a lower support rod extending through said fixing plates in a direction transverse to said first leg and said seat bars, said movable bar being pivoted to said fixing plates. 
     
     
         6 . The stretching exercise apparatus as claimed in  claim 5 , further comprising an upper support rod disposed transversely on said upright bar in proximity to a top end thereof and spaced apart from said seat frame, and an upper rotatable knob connected removably to said upright bar and said upper support rod, said leg lift frame further including an ankle engaging rod extending transversely through said movable bar. 
     
     
         7 . The stretching exercise apparatus as claimed in  claim 2 , wherein said bench unit further includes a lower rotatable knob connected removably to said first leg and said upright bar. 
     
     
         8 . The stretching exercise apparatus as claimed in  claim 2 , wherein said second leg frame includes a bottom rod, two support rods having bottom ends connected to said bottom rod and top ends connected respectively to bottom sides of said seat bars, and two pulley sets disposed on said bottom rod, said support rods being disposed between said pulley sets. 
     
     
         9 . The stretching exercise apparatus as claimed in  claim 8 , wherein each of said pulley sets includes a seat fixed to said bottom rod, and a pulley disposed on said seat. 
     
     
         10 . The stretching exercise apparatus as claimed in  claim 4 , wherein said upright bar includes two upper pulleys disposed on a top portion thereof, said first leg frame further including a lower pulley disposed on a bottom side of said first leg and facing said hook, said elastic cord being looped around said upper and lower pulleys.
