Abstract
An improved exercise apparatus, having two rails in parallel relation supported on a frame. Supported by each rail are two travellers, the four travellers for engagement with the limbs of the user. Each pair of travellers is supported by the rail one above the other, with the bottom travellers extending laterally below the rails of the apparatus. The travellers ride within grooves in the rails. An endless chain is suspended between the rails. When the travellers are coupled to the endless chain, the user encounters a resistive force from a force resistance system. Each set of travellers is selectively coupled to the endless chain.
Claims20
An improved exercise apparatus for use in exercising one or more of the limbs of a user comprising:
- a) a pair of rails mounted on a supportive frame of the apparatus;
- b) first and second travellers supported on each of said pair of rails, said first and second travellers being supported on each of said pair of rails one above the other, said travellers adapted to engage the limbs of the user during exercise;
- c) endless chain means deployed in a single loop and supported between said rails;
- d) means for selectively coupling said travellers to said endless chain means;
- e) force resisting means;
- and
- f) means for connecting said endless chain means to said force resisting means wherein the user of the apparatus encounters resistance from said force resisting means when the user applies a force to said travellers.
An improved exercise apparatus for use in exercising one or more of the limbs of a user comprising:
- a) a pair of rails mounted on a supportive frame of the apparatus;
- b) first and second travellers supported on each of said pair of rails one above the other, said travellers being adapted for engaging the limbs of the user during exercise;
- c) endless chain means deployed in a single loop mounted on said supportive frame;
- d) first means for selectively coupling said first traveller to said endless chain means and second means for selectively coupling said second traveller to said endless chain means;
- e) force resisting means;
- and
- f) means for connecting said endless chain means to said force resisting means wherein the user of the apparatus encounters resistance from said force resisting means when the user applies a force to said travellers.
An improved exercise apparatus for use in exercising one or more of the limbs of a user comprising;
- a) a pair of rails mounted on a supportive frame of the apparatus;
- b) at least one traveller supported on each of said pair of rails, said travellers adapted to engage the limbs of the user during exercise;
- c) endless chain means deployed in a single loop mounted on said supportive frame;
- d) means for selectively coupling said travellers to said endless chain means;
- e) force resisting means for variably adjusting brake current to vary brake torque level corresponding to stroke displacement of said travellers, wherein said force resisting means includes means for calculating various stroke parameters and wherein brake torque level may be continuously varied during each traveller stroke from a minimum of zero to a predetermined maximum torque level for achieving a programmed force or velocity profile.
