Abstract
A resistive device that enables adjustable resistance in at least one direction using an attachment system and associated eddy current braking system. The resistive device can be bench-mounted, in some embodiments, used for physical therapy caused by neuromuscular diseases, such as stroke and cerebral palsy, orthopedic disorders, general disuse, or even for overall fitness.
Claims19
A resistive device comprising:
- a structure assembly having a first section and a second section, the first section being movably connected to the second section;
- and
- an eddy current braking system comprising:
- an input member connected to the first section of the structure assembly for movement therewith,
- a magnetic assembly having at least one magnet pair,
- a transmission system operably coupled to the input member receiving the relative movement thereof and driving an output member in response thereto, and
- a conductor being operably coupled to the output member for movement therewith in response to movement of the output member, the conductor being positioned relative to the at least one magnet pair of the magnetic assembly to induce eddy currents therein whereby a resistive force is generated opposing movement of the first section of the structure assembly relative to the second section of the structure assembly in at least one direction.
