  • Patent number: 4233844
    Abstract: A wheelchair ergometer provides for the stationary exercise of a subject in a wheelchair and includes a wheelchair mounted on a support with the driving wheels mounted on an elongated central shaft. A set of flywheels is mounted at either end of the central shaft and has provision for mounting weights corresponding to the weight of the subject. The flywheels load the central shaft and simulate the translational inertia present in a moving wheelchair. A torque platform is supported by bearings from the central shaft and is coupled to a friction type brake which may be selectively tightened about the central shaft to cause the brake and platform to deflect in relation to the torque applied to the central shaft. A scale fixedly mounted adjacent the torque platform measures the deflection to indicate the torque on the shaft.
