Benefits of technology

The present invention is an elliptical exercise machine with a treading depth adjustment mechanism. The purpose of this invention is to reduce the load on the motor and minimize the cost by using an adjusting unit to adjust the treading depth of the rear end portions of the stepping bars and move the pivot portions of the rocking rods of the guiding unit relative to the pivot shaft of the damping unit. This helps to reduce the driving load and allows for the use of a low-cost motor.

Problems solved by technology

Therefore, the power drive bears a heavy load.
Consequently, the power drive needs to use a high power motor, which increases the cost.

Abstract

An elliptical exercise machine with a treading depth adjustment mechanism includes a frame, a swing unit, a pedal unit, a damping unit, a guiding unit and an adjusting unit. The swing unit includes a pair of swing arms swingable relative to the frame. The pedal unit includes a pair of stepping bars respectively pivotally connected to the swing arms. The damping unit is adapted for providing swing damping to the stepping bars and includes a rotating wheel mounted at the frame and a resistant member for providing a damping resistance to the rotating wheel. The guiding unit includes a pair of rocking rods swingable relative to the frame and adapted for supporting sliding movement of the stepping bars and a pair of connection rods for driving the rotating wheel to rotate. The adjusting unit is adapted for adjusting the treading depth of the rear end portions of the stepping bars.

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 exercise machine with a treading depth adjustment mechanism.[0003]2. Description of the Related Art[0004]Taiwan Patent M431718 discloses a treading depth adjustable elliptical exercise machine, which comprises a frame base, a flywheel set, two pedal assemblies, two handlebars, and a pedal-lifting mechanism. The pedal lifting mechanism comprises a lifting frame pivotally mounted at the frame base, and a tilt adjustment mechanism mounted at the frame base for adjusting the tilt angle of the lifting frame. The tilt adjustment mechanism comprises a power drive, a driving bar, and a bracket pivotally connected between the frame base and the lift frame. Each pedal assembly comprises a swing arm pivotally connected to the frame base, a stepping bar pivotally mounted at a bottom side of the swing arm, a first connection rod piv...
