    摘要： An improved eddy current braking system for fly wheel braked exercise equipment includes the use of a flat aluminum disc and electromagnets to either side of the disc adjacent to the periphery thereof, with the electromagnets containing multiple pole pieces to multiply the torque so as to reduce heating and power consumption. The utilization of aluminum achieves a flat torque versus speed characteristic vis-a-vis copper discs over the normal operating speed range. Additionally, the utilization of aluminum prevents the warpage associated with copper.

    摘要： A rotary exercise apparatus includes a frame which supports a seat assembly and a rotary crank mechanism. The frame has two sets of legs, one which supports the apparatus in an upright position where the crank mechanism can be used by someone sitting on the seat assembly to perform upper body exercises, and another which supports the apparatus in a reclined position where the crank mechanism can be used by someone sitting on the seat assembly to perform lower body exercises. The crank mechanism permits variable amounts of resistance to be imparted against its rotation by urging a shoe having a high friction liner against a rotatably mounted shaft that carries the crank arms. The location of the crank mechanism along the frame and the length of the arms are adjustable to accommodate different size users. In addition, the arms are replaceable to permit different size and shape arms carrying appropriate engagement devices to be used for each type of exercise. When the apparatus is in its reclined position, the seat assembly provides both a seat and a back rest.

    摘要： A portable exercise device for releasable securement to the vertical edge of a door or other vertically extending structure. The device comprises a pedal assembly, comprising an elongated axle from which a diametrically opposed pair of arms extend, with each arm having a respective pedal mounted thereon. The pedal assembly is arranged to be rotated about the longitudinal axis of the axle by the application of force to the pedals. The axle is mounted within a holder having a clamping bracket. The holder includes a tension bar and a frictional material split sleeve disposed about the axle to frictionally engage, the peripheral surface thereof. The tension bar is adjustable to vary the frictional engagement between the sleeve and the axle so that the user can select a desired amount of pedalling resistance the device will provide. Each pedal includes finger notches to enable the user to rotate the pedals by hand. Stirrups are provided to ensure that the user's feet, when rotating the pedals, do not slip off the pedals.
