Abstract
An elliptically moving mechanism includes: a track disc formed with two tracks, the two tracks perpendicularly intersecting each other; a transmission ring rotatably fitted around a circumference of the track disc; a rocking arm positioned under the track disc; and two slide members disposed on a top face of the rocking arm. The rocking arm is connected to the two tracks via the two slide members. The two slide members are slidable along the two tracks respectively. When the transmission ring is rotated, the rocking arm is driven by the transmission ring to move in an elliptical path. The elliptically moving mechanism is easy to manufacture and assemble and has a small volume and is lightweight. Moreover, the mechanism provides different elliptical paths of different sizes.

An elliptically moving mechanism comprising:
- a track disc having the form of a circular disc and formed with a first track and a second track perpendicular to the first track, the first and second tracks intersecting each other at an intersection where a hollow section is formed, bottom sides of the two tracks and a bottom end of the hollow section being open;
- a transmission ring, which is a ring body;
- a transmission section being disposed on an outer circumference of the transmission ring, the transmission ring being rotatably fitted around a circumference of the track disc;
- a rocking arm, which is an elongated member;
- a first slide member and a second slide member, the first slide member being rotatably fitted on a first shaft rod of the rocking arm and positioned on a top face of the rocking arm;
- the second slide member being rotatably fitted on a second shaft rod of the rocking arm and positioned on a the top face of the rocking arm;
- the rocking arm being positioned under the track disc with the two slide members connected to the two tracks, the first slide member being disposed in the first track and slidable along the first track;
- the second slide member being disposed in the second track and slidable along the second track;
- and
- a link member positioned between the transmission ring and the rocking arm, when the transmission ring is rotated, the rocking arm being driven by the transmission ring via the link member.
