Abstract: A track-adjusting method and a track-adjusting mechanism are applicable to an elliptical exercise apparatus using a linkage system to generate a cyclic exercise track. The track-adjusting method and the track-adjusting mechanism provide the elliptical exercise apparatus with additional exercise tracks by displacing at least one set of horizontally symmetrical pivotal joints in the linkage system, so as to allow diverse training programs and improved exercise effects.

Abstract: An elliptical exercise apparatus includes a body having a base frame and two supporting frames uprighted at two opposite sides of the base frame; a pair of lead swing arms each having an upper end pivotally coupled with the corresponding supporting frame wherein a sliding treadle assembly having a lower end provided with a treadle portion is axially slidably attached to the lead swing arm; a pair of subsidiary swing arms each having one end pivotally coupled with the base frame wherein a subsidiary sliding sleeve pivotally coupled with the sliding treadle assembly via a pivot is axially slidably attached to the subsidiary swing arm; and a rotational shaft transversely and pivotally coupled with the base frame, wherein at each of two ends of the rotational shaft, a vertical rotational link has one end coupled with the rotational shaft and an opposite end pivotally coupled with the sliding sleeve.

Abstract: A hip-abduction stepper exercise apparatus primarily comprises a base and two pedal assemblies settled abreast on the base. Each of the pedal assemblies includes a pedal, a vertical movement module, an expanding movement module, and a recovery module. The pedal is settled on the vertical movement module while the expanding movement module is settled on the base so that the two pedals can depart from or come close to each other with respect to a level position. The vertical movement module is connected to the expanding movement module so that the two pedals can vertically move in a direction non-perpendicular to the ground. The recovery module is connected to the vertical movement module and the base and provides an external force for returning the vertical movement module and the expanding movement module to initial positions thereof.

Abstract: An elliptical exercise machine with an adjustable exercising track comprises a framework, having a flywheel, a crank settled on the flywheel, and at least two parallel rails; a wheel assembly, comprising two wheel-shafts arranged at two sides of the crank and two wheels slidably coupled to the rails; a handle-shaft assembly, comprising a pair of handle-shafts disposed at two sides of the framework for being gripped by a user; a stepping-pedal assembly, comprising two pedals coupled to two pedal-shafts which are linked to the handle-shafts; and a pair of adjusting assemblies for shifting positions of joints of the pedal-shafts and the wheel-shafts along the wheel-shafts. By shifting the positions of joints of the pedal-shafts and the wheel-shafts, a minor axis of the elliptical exercising track can be lengthened or shortened and consequently the elliptical exercising track can be non-proportionally scaled.

Abstract: An exercise training system primarily comprises a guiding-track generating unit and a controlling unit wherein the controlling unit can direct the guiding-track generating unit to produce a variable circulative guiding track for an exerciser to move accordingly and detect the exerciser's motion to provide objective data of performance assessment.

Abstract: An elliptical exercise machine with adjustable exercising orbit substantially comprises a framework, an upright support disposed thereon, a flywheel disposed inside the upright support, a crank settled on the flywheel, at least two parallel rails arranged adjacent said framework, a wheel means comprising two wheel-shafts arranged on each side of said crank and each has a wheel which is coupled to said rail, a handle-shaft means comprising a pair of handle-shafts disposed on each side of the upright support with the top portions for users' handling, a running-pedal means comprising two pedals respectively coupled to two pedal-shafts which are linked to said handle-shafts for users' pedaling, a pair of adjust-devices on the wheel-shafts which are pivotally connected to the pedal-shafts for adjust the position of joints of pedal-shafts and wheel-shafts by moving axially along the wheel-shafts forwards and backwards.

Abstract: A medical therapeutic treadmill capable of automatically adjusting its rail height includes, a base having a treadmill platform disposed on the base, a control panel disposed at the front of the base; and a rail set having a rail separately disposed on both sides of the base, characterized in that the bottom of each rail has a rail height adjusting mechanism that can simultaneously drive the rail to move up and down, so that the height adjusting mechanism can adjust the height of the rails on both sides of the treadmill, and quickly and easily adjusting the rail height for patients.
