    摘要: A cycle with tapered drivetrain connections. The cycle includes a frame, a crank rotatably connected to the frame, and a driven wheel rotatably connected to the frame. The crank includes a crank arm and a crank spindle rotatably connected to the frame and non-rotatably connected to the crank arm. The crank spindle includes a crank mating surface to interface with the crank arm. The diameter of the crank spindle continuously decreases along at least a portion of the crank mating surface in a lateral direction. The crank arm includes a crank bore to interface with the crank mating surface. At least a portion of the crank bore has a diameter that continuously decreases in lateral direction. At least a portion of the crank bore taper has a taper rate and diameter equal to a taper rate and diameter of at least a portion of the crank spindle taper.

    摘要: An elliptical exercise machine features a pair of translating members to which a pair of foot members is axially secured. The foot members each pivots with respect to the associated translating member. The generated motion allows a user to lock a knee before beginning downward movement and allows a user to bend the same knee before beginning forward movement such that the motion is more natural for the user.
