  • Patent number: 4664371
    Abstract: An exercise treadmill comprising a frame including rotatable drive and idler rolls, an endless mat extending around the drive and idler rolls and along the frame to support a person thereon, and a motor connected to the drive roll to rotate that roll and to drive the mat. First and second railings are connected to the frame and longitudinally extend above and along first and second lateral sides thereof respectively to help balance a person on the mat. The exercise treadmill is supported on a surface by an assembly including a tubular housing connected to the frame, a support arm slidably supported in the tubular housing, and a spring secured within the tubular housing and urging the support arm downward into engagement with that support surface.

  • Patent number: 4630818
    Abstract: The invention relates to a torque metering device for a bicycle-type ergometer, in which ergometer the braking force is steplessly adjustable and in which the rotating movement is compensated by means of a flywheel. The rotating movement of the flywheel can be braked by means of a belt (5) which is pressed against the outer periphery of the flywheel and moves limitedly with the flywheel. The movement of the belt (5) with the flywheel is restricted by means of a spring member (6) connected to one end of the belt and the frame structure of the ergometer. In order to provide a reliable and easily readable metering device, the device is so constructed that it comprises a pin member (7) fastened on the belt (5) and means (8) for rotating an indicator (10) journalled for rotation. The rotating means (8) of the indicator are journalled on the frame structure (1) at the central portion thereof.

  • Patent number: 4419890
    Abstract: A bicycle ergometer, where with the aid of a spring balance the braking effect of a band brake on the rim of a flywheel is measured and the braking effect may be regulated. The band, spring and indicator are normally fastened to a ball-bearing fork in the hub of the wheel, thus the tightening of the band strains the bearings. The fluctations of the indicator caused by the uneven friction and the vibrations characteristic of the spring have been reduced by a hydraulic damper. In this invention the fork has been removed. The band, spring and indicator are fastened to a weight resting on the flywheel and steered by a groove on the rim of the wheel. The mass of the weight reduces the indicator fluctuations.
