US Patent For A Rowing Exercise Machine With Effective Resistance Mechanism
Mark C. Termion (Winfield, IL), Zhi Lu (West Dundee, IL), Eric C. White (Streamwood, IL) and Douglas B. MacDonald (Des Plaines, IL) have emerged with a simple and effective rowing exercise machine, which has been awarded the US Patent 7,226,397 recently.
According to anarticle in www.findthatpatent.com, the rowing exercise machine has a simple effective resistance mechanism, which replaces the resistive brakes typically used in the prior art. The resistance mechanism of the machine consists a first coupling between the first and second spaced disks, which prevent rotation with the help of a resiliently deformable as well as a tensionable spiral in between. The second coupling of the device comes between one of the disks and a user handle for resisting the concordant movement of the user on a seat along a track as well as the movement of the handle.
