Benefits of technology
The present invention is an elliptical trainer with a resilient unit that helps prevent interference with the user, has a simple structure, and is easy to maintain. The design of the trainer ensures that the resilient units are located near the pivot points of the arm members and the front end portions of the pedal shafts, while keeping the rear end portions of the pedal shafts far from the pivot points. This helps to produce an inertial-elastic force and prevents the resilient units from interfering with the user during operation.
Problems solved by technology
However, because these detent cables are respectively connected between the rotary interlocking members and the pedal shafts, the path of these detent cables is quite long, and the long opposite ends of the detent cables are exposed to the outside of the support rack.
Thus, the exposed opposite ends of the detent cables can interfere with the user, and these detent cables are prone to elastic fatigue after a long period of use, and the maintenance of these detent cables is also very inconvenient.

Embodiment Construction
[0021]Referring to FIGS. 1, 2 and 3, an elliptical trainer with a resilient unit in accordance with a first embodiment of the present invention is shown. The elliptical exercise machine comprises a frame 10, an exercising unit 20, a pedal unit 30, a damper 40, a guide unit 50, a pair of resilient units 60, a handlebar unit 70, a constraint unit 80, and a shell 90.
[0022]The frame 10 comprises a base 11, and a support 12 fixedly mounted to a front side of the base 11. The support 12 comprises an upright post 13 located at a top side thereof, a transverse axle 131 fixedly and transversely extending across the upright post 13 near a top end thereof, and an extension bar 132 extended from the upright post 13 below transverse axle 131.
[0023]The exercising unit 20 comprises a pair of arm members 21 respectively pivotally connected to two opposite ends of the transverse axle 131 of the frame 10 and alternatively turnable back and forth about the transverse axle 131. Each arm member 21 compr...

An elliptical trainer with a resilient unit includes a frame, an exercising unit axially disposed on the frame, a pedal unit pivotally mounted to the exercising unit, a damper for providing a damping resistance to the pedal unit, a guide unit for supporting the pedal unit and guiding the pedal unit to slide thereon, and a pair of resilient units respectively disposed in proximity to the pivoted junctions between the exercising unit and the pedal unit for enabling a pair of rear end portions of the pedal unit to be constantly kept far from a pair of pivot-connection portions of the exercising unit so that an inertial-elastic force is produced during operation of the elliptical trainer.
Description
BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to fitness equipment technology and more particularly, to an elliptical trainer with a resilient unit.[0003]2. Description of the Related Art[0004]A fitness machine (US Patent Application 2013 / 0053218) consisting of a frame, a pedal unit, a driving unit and a damper is known. The frame comprises a base, an upright post fixedly connected to the base, a support rack connected between the upright post and the base, and a shaft fixedly connected between the upright post and the support rack. The pedal unit comprises a pair of rotary interlocking members respectively sleeved onto the shaft, a pair of sleeves respectively mounted around the rotary interlocking members, a pair of arm members respectively connected to the sleeves, and a pair of pedal shafts respectively pivotally connected to the arm members. The driving unit comprises a pair of detent cables slidably inserted through the support r...
