  • Patent number: 9662533
    Abstract: A self-compensating tire compression device is provided for use with a trainer. The device attaches to a frame, such as a bicycle, that holds the axis of a driving wheel fixed. The device has a pivoting portion that presses a driven portion of a resistance device against the driving wheel. The pivoting point of the pivoting portion is located on the trainer to provide a static contact pressure between the driving wheel and the driven wheel, and when the driving wheel begins to rotate and the resistance device begins to resist the rotation, the contact pressure between the driving wheel and the driven wheel increases to prevent slippage between the two wheels.

  • Patent number: 9511271
    Abstract: A two-stage resistance trainer is provided having a first magnet that is in proximity to a rotating wheel, and a moveable second magnet that is linked to the first magnet. The first magnet is moved when the rotating wheel rotates and the second magnet is moved closer to the rotating wheel to add a second order effect to the resistance. The trainer is capable of adjusting the first magnet position in relation to the rotating wheel to provide a different relationship of speed to resistance.

  • Patent number: 9393475
    Abstract: A progressive resistance device is provided having a cylinder having an outer wall which defines an inner chamber. The cylinder is carried on an axle and is rotatable thereabout. An eccentric axle surrounds the axle and is rotatable relative the axle. A magnet carrier partially encircles the eccentric axle and carries a magnet. A bearing is nested between the magnet carrier and the eccentric axle. The magnet carrier is rotatable about the eccentric axle on an axis which is eccentric to the axle's axis, whereby the distance between the magnet and the outer wall is variable as defined by the rotative position of said housing relative said outer wall, which rotative position is governed by the speed of rotation of the cylinder. The progressive resistance device described herein is adapted for use as a roller on a bicycle trainer.

  • Patent number: 9381396
    Abstract: A collapsible folding training device is provided having a rear frame portion that contains a resistance device. The resistance device uses eddy currents and has a pivoting magnet internally that creates progressively increasing resistance as speed increases. An arm is attached to the rear frame portion that can pivot from a stored position to an in-use position. At the opposite end of the arm, a front frame is attached where it can affix a portion of a driving mechanism, such as a bicycle. The front frame supports and stabilizes the driving mechanism. The arm sets the distance between the front frame and the resistance device.
