Exercise machine

An exercise machine for providing rope pull/rowing exercise and bicycling exercise comprising:

• a housing;
• shaft means extending through said housing and being rotatably carried by said housing, said shaft means comprising a first shaft extending through said housing and a second shaft generally parallel to said first shaft;
• bicycle pedal means rigidly attached to said shaft means external to said housing;
• rope pulling means rotatably connecting to said shaft means, said rope pulling means extending external to said housing;
• resistance means mounted in said housing and operatively connected to said shaft means to resist rotation of said shaft means;
• clutch means for rotatably connecting said shaft means to provide for said rope pulling/rowing exercise from said rope pulling means and said bicycling exercise from said bicycle pedal means;
• and
• gear reduction means connected to said shaft means linking said rope pulling means and said bicycle pedal means with said resistance means and including at least one pair of rotating components having unequal diameters, a first said rotating component of said pair being mounted upon said first shaft and a second said rotating component of said pair being mounted upon said second shaft, said first and second rotating components being coupled together for transferring rotation between said first and second rotating components of said pair.

• shaft means extending through said housing and being rotatably carried by said housing;
• bicycle pedal means rigidly attached to said shaft means external to said housing;
• rope pulling means rotatably connecting to said shaft means, said rope pulling means extending external to said housing;
• resistance means mounted in said housing and operatively connected to said shaft means to resist rotation of said shaft means;
• clutch means for rotatably connecting said shaft means to provide for said rope pulling/rowing exercise from said rope pulling means and said bicycling exercise from said bicycle pedal means, said clutch means comprising at least one unidirectional clutch oriented in a manner for operation of said bicycle pedal means independently of said rope pulling means, as well as operation of said rope pulling means independently of said bicycle pedal means;
• and
• gear reduction means connected to said shaft means linking said rope pulling means and said bicycle pedal means with said resistance means and including at least one pair of rotating components having unequal diameters and being coupled together, said pair of said rotatable components of said gear reduction means being mounted on said shaft means.

An exercise machine usable for exercises involving pedalling against resistance and pulling against resistance comprising:

• a housing;
• a first shaft extending through said housing, said first shaft being rotatably carried by said housing;
• a second shaft rotatably carried by said housing;
• resistance means operatively engaged with said first shaft and said second shaft for resisting rotation of said first and said second shafts;
• said resistance means being mounted at least in part to said housing;
• pedalling means mounted outside of said housing and attached to said first shaft for imparting rotation to said first shaft;
• pulling means attached to said second shaft for imparting rotation to said second shaft, said pulling means having means for grasping positioned externally to said housing;
• gear reduction means mounted on said first and second shafts for coupling said pedalling means with said resistance means, for coupling said pulling means with said resistance means, and for enhancing a resistance produced by said resistance means;
• bearing members for said first and second shafts for allowing rotation of said pedalling means and said pulling means on said first and second shaft;
• and
• unidirectional clutches for connecting said pedalling means and said pulling means on said first and second shafts upon rotation in a first direction, but releasing upon rotation in a second direction.
