Abstract

A workout device with a foot-oriented elliptical loop is provided and bilaterally equipped with a transmission rod, a first link rod, a driving rod, a second link rod, a swing arm, and a supporting rod. The transmission portions are pivotally coupled to cranks to enable the cranks to undergo revolution. The supporting rods each have a supporting portion to support a user's feet. The aforesaid rods interact with each other. The supporting portions of the supporting rods move along a closed elliptical loop with segmental junctions spaced apart by a relatively short distance, such that the user's treading process is prevented from undergoing abrupt descents, un smooth transitions, and thus jolts.

Claims5

Dependent claims

A workout device with a foot-oriented elliptical loop, comprising:

a base mounted on a supporting surface;
a crank mechanism having two opposing cranks coupled to the base coaxially and pivotally;
and
two link rod mechanisms disposed on the left and right of the base, respectively, and each comprising a transmission rod, a first link rod, a driving rod, a second link rod, a swing arm, and a supporting rod, the transmission rod having a first transmission portion and a second transmission portion, the first and second transmission portions being pivotally coupled to the cranks to enable the cranks to move upward, downward, forward, and backward and thereby undergo revolution relative to the base, the first link rod having first and second end portions, the first end portion being pivotally coupled to the first transmission portion, the driving rod having a first driving portion and a second driving portion, the first driving portion being pivotally coupled to the second end portion, the second link rod having a first pivotally rotating portion, a second pivotally rotating portion, and a transit portion, the first pivotally rotating portion being pivotally coupled to the second driving portion, the transit portion being pivotally coupled to the base, the swing arm having a pivotally connecting portion and a swinging portion, the pivotally connecting portion being pivotally coupled to the second pivotally rotating portion, the supporting rod having a first connection portion, a second connection portion, and a supporting portion, the first connection portion being pivotally coupled to the second transmission portion, the second connection portion being pivotally coupled to the swinging portion, and the supporting portion supporting a user's feet.
