An elliptical exercise apparatus includes a main device, a guider frame rotatably connected to the main device via an axis, the guider frame being rotatable relative to the ground and the main device, two crank units respectively rotatably connected to a right side and a left side of the main device, two supporting sets both interconnected between the two crank units and the guider frame, two swing links respectively pivotally connected to two sides of the main device, and two control links both interconnected between the two supporting sets and the two swing links. Under this arrangement, when the elliptical exercise apparatus is folded, one supporting set abuts against the guider frame and one corresponding control link simultaneously, so that when the user moves the elliptical exercise apparatus which is folded, the structure of the elliptical exercise apparatus prevents unwanted motion of the cranks and the supporting sets. |

1. An elliptical exercise apparatus comprising:
a main device; a guider frame rotatably connected to the main device via a first pivot which defines a first transverse pivot axis, the guider frame being rotatable relative to the ground and the main device, the guider frame positioned in the usable position when the guider frame is rotated to the ground, the guider frame rotated into the storage position when the guider frame is rotated to the main device, the guider frame having two track members respectively assembled at a right side and a left side thereof, each track member having a front end and a rear end; two crank units respectively rotatably connected to the main device, the two crank units being rotatable in a first direction or a second direction; two supporting sets each having a first portion, a second portion and a third portion, the first portion of each supporting set rotatably connected to each corresponding crank unit, the first portion of each supporting set being rotatable along a circular path with a rotation of each corresponding crank unit, the second portion of each supporting set slidably mounted on each corresponding track member; two swing links respectively pivotally connected to the main device; and two control links each having a first portion, a second portion and a third portion, the first portion of each control link rotatably connected to each corresponding swing link, the second portion of each control link configured to support the user's corresponding foot, the third portion of each control link rotatably connected to the third portion of each corresponding supporting set; wherein, when the guider frame is rotated into the storage position, the second portion of one of the supporting sets abuts against the guider frame for defining a first abutting relation, the first abutting relation preventing the second portion of one of the supporting sets from further sliding upwardly and preventing the first portion of one of the supporting sets from being rotated along the circular path in the first direction and a first further abutting component selected from the group consisting of the crank units, the supporting sets, the swing links and the control links abuts against a second further abutting component selected from the group at an abutting portion for defining a second abutting relation, the second abutting relation preventing the first portion of one of the supporting sets from being rotated along the circular path in the second direction. |
