Rowing machine with improved mechanical features

Abstract

A rowing exercise machine having an improved user interface. The user interface has a cable for accepting user exercising stroke movements each stroke having a power and return portion. The cable is carried on a cable drum which is mounted on a shaft such that when the cable is unwound and rewound rotation to the shaft is imparted. A flywheel is connected to the shaft for receiving and conserving angular momentum imparted thereto. The machine also includes a brake for opposing the rotational displacement of the flywheel. The user interface further includes a stainless steel eye staked into one end of a strain relief spring with an end of the cable being staked in the opposite end of the spring. A handle is secured to the eye which is capable of withstanding the concentrated forces to which the user interface is subjected. A nylon cable port is mounted on the cable drum housing, the cable port having a centrally located aperture therein with cross sections which are generally oval in shape to allow the cable to be pulled out from the cable port along a line generally parallel to the base of the cabinet or at an upward angle with respect to the base without rubbing against the cable port. The cable drum has an angled sidewall to allow only one row of cable to be wound there around so as to maintain the forces opposing the user constant and controllable. The cable drum further includes a guide plate positioned between the end plates of the drum so as to lightly rub against the cable and guide it onto the drum in order to prevent tangling of the cable if it is not rewound fast enough.
