An elliptical exerciser includes a frame, first and second magnetic control wheel units, first and second swing levers, first and second transmission rods, first and second guiding mechanisms, first and second pedal rods, and a magnetic mechanism. When the first and second swing levers and the first and second transmission rods are swung forward and rearward synchronously and the first and second pedal rods are pedaled up and down to slide forward and rearward, the first and second pedal rods pivotally connected with bottom ends of the first and second swing levers are to do a tread motion of an elliptical trajectory.

An exercise machine comprises an oval-shaped structure with a fly wheel, two driving arms, two swing handle and two slidable bars. The fly wheel of the oval-shaped structure simultaneously drives the driving arms and the swing handles, and the slidable bars are pivoted onto the corresponding swing handles and rest on corresponding shafts of the fly wheel such that the movements of the slidable bars are not limited by the driving arms and can be longer than the travel stroke of the fly wheel.

An oval transmission structure utilizes lower ends of swaying moving shafts at two sides thereof to pivot to front ends of push-pull shafts, whose front portions slope to a determined angle. Rear portions of the push-pull shafts offer treadle frames for treadles to dispose with feet. Rear portions of the push-pull shafts further offer a track frame. An assistant device provides a sliding block with a fixing bolt superimposed at a side of the lower portion of the swaying moving shaft. An attached shaft pivoted to a side of the sliding block connects to an axle bolt of a transmission shaft, whose front end axially connects to a crank, whose rear end serially connects to a track wheel and whose middle determined position disposes a sliding wheel thereunder. The reciprocation brought about by the feet, the two cranks axially trigger the front ends of the two transmission shaft for achieving a relative oval action. The axle bolt motivates the attached shaft for driving the sliding block to move the lower portions of the two swaying moving shafts to achieve a relative displacement. Concurrently, the sliding wheel reciprocating flat on the track frame permits upper portions of the swaying moving shafts to sway oppositely. The two treadle frames accordingly slide on the track wheels. A V-shaped leverage of the transmission shaft could attain a favorable transmission effect in time of users operating the back-and-forth reciprocation.

A stepping and waist twirling exercise machine includes left and right stepping rods having left and right through holes and left and right stepping platforms having left and right shafts. The shafts are inserted into bearings provided in the through holes. Left and right coil rollers are provided on the shafts. The coil rollers are provided with left and right rope units each having left and right ropes. The ropes have first ends and second ends. The first ends of the ropes are secured to two sides of the coil rollers, respectively. The second ends of the ropes are secured to a frame and a machine base, respectively. When the left and right stepping platforms are stepped downward in turn, the left and right rope units will bring the left and right coil rollers to turn left or right synchronously, providing active or passive stepping and waist twirling exercise.

An auxiliary structure to improve efficacy of a fitness equipment includes a pair of swing bars pivoted to a pair of traction bars wherein in turn pivoted to a crank; the crank drives a sprocket and a resistance control wheel for both swing bars to drive both traction bars to travel up, down, back and forth; each pedal is disposed with a roller to travel in a slide attached to the traction bar and is pivoted to a pull-and-push connection bar, which in turn is pivoted to a transmission connection bar; each transmission connection bar is pivoted to a support; each mid section of the transmission connection bar is pivoted to an active connection bar, which in turn is pivoted to the swing bar; and each pedal is dragged by the push-and-pull connection bar driven by the transmission connection bar when both swing bars alternatively swing to drive the transmission connecting bar to increase longitudinal travel ranges of both pedals for providing adequate exercise amount for waist and legs of a user to improve exercise efficacy.
摘要:
An elliptical trainer comprises a frame set, two first transmission rods, two second transmission rods, two footboard assemblies, a holding flywheel assembly, a stand flywheel assembly, and two eccentric link rods. When a user is stepping the two footboard assemblies and taking exercise with elbows on the two second transmission rods, the two footboard assemblies may be stepped up and down to recycle and each second transmission rod may be rotated to reciprocate along an arc and centered in a stand ear. At this time, each drag rod of two stand ears arranged right and left may pull the corresponding eccentric link assembly to rotate 360 degree and the torque of the third flywheel may not overlap each drag rod of each eccentric link assembly vertically. Accordingly, the arrangement of each eccentric link assembly may prevent the swing operation from being stuck to pause or operate unsmoothly.
