Abstract

An elliptical exercise apparatus includes: a main frame; a crank assembly mounted on a rear end of the base support; a pair of swing rods pivotally connected to a front and of the base support; a pair of couplers slidably and respectively mounted on lever portions of the swing rods; a pair of guide rails, each being pivotally connected to the respective lever portion and the crank assembly so as to perform a reciprocating movement when the lever portions are swung; a pair of footrests slidably mounted on the guide rails to be alternately moved along reciprocating routes respectively; and a pair of linkages, each being pivotally connected to a bottom end of the respective swing rod and the respective footrest such that the footrests are moved alternately and respectively along elliptical paths.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority of Taiwanese Application No. 095112453, filed on Apr. 7, 2006.BACKGROUND OF THE INVENTION [0002]1. Field of the Invention[0003]This invention relates to an elliptical exercise apparatus, more particularly to an elliptical exercise apparatus which is adjustable to provide a satisfactory elliptical path for suiting different operators.[0004]2. Description of the Related Art[0005]A conventional elliptical exercise apparatus generally includes footrests which are affixed to footrest shafts that perform a reciprocating movement by means of swinging of swing rods. Thus, during operation, only a limited elliptical route of the footrests can be achieved. As a result, the operator cannot obtain a sufficient amount of exercise, and cannot exercise with comfort. In a Taiwanese Utility Model Patent No. M282705 filed by the applicant, there is disclosed an elliptical exercise apparatus, which includes footrests that are...
