Folding elliptical exercise machine

摘要

A folding elliptical exercise machine includes a main frame, a guider frame coupled to the main frame for being moved between a use position and a storage position, a rotatable crank mechanism arranged on the main frame, two supporting members coupled between two crank units of the rotatable crank mechanism and two tracks of the guider frame, and two pedals coupled to the two supporting members. The engagement of the locking device is affected by the position of the guider frame. The locking device has a latch which can be located in an unlocked position where it is not interfering with the rotatable crank mechanism when the guider frame is oriented in the use position, or can be located in a locking position for stopping the rotatable crank mechanism from rotating when the guider frame is moved from the use position to the storage position.

1. A folding elliptical exercise machine, comprising:
a main frame; a guider frame pivotally coupled to the main frame for being moved between a use position and a storage position, and the guider frame having two tracks; a rotatable crank mechanism having a crank shaft, two crank units, a flywheel and a transmission mechanism; the crank shaft pivotally arranged on the main frame; the two crank units fixed on two ends of the crank shaft respectively; the flywheel pivotally coupled to the main frame; the transmission mechanism coupled to the crank units and the flywheel; two supporting members respectively having a rotating portion, a reciprocating portion and a supporting portion; the two rotating portions pivotally coupled to the two crank units respectively, and moving along a circular path about the crank shaft; the two reciprocating portions carried by the two tracks respectively; the two reciprocating portions moving back and forth along the two tracks respectively while the guider frame is oriented in the use position; two pedals respectively coupled to the two supporting portions of the two supporting members; and a locking device arranged between the guider frame and the rotatable crank mechanism, the position of the locking device affected by the position of the guider frame, the locking device having a latch having an unlocked position and a locking position; the latch corresponding to locate at the unlocked position and not interfering with the rotation of the rotatable crank mechanism when the guider frame is in the use position; the latch corresponding to locate at the locking position for preventing a predetermined element of the rotatable crank mechanism from rotating when the guider frame is not in the use position.
