Abstract

An elliptical exerciser includes a base, a body, a transmission device, an adjustable upright post, a pair of handles and two foot pedal rods. The post is composed of an upper tube which is retractably inserted in a lower tube. Two respective mediate portions of the two handles are connected to two sides of the upper tube. Two ends of each foot pedal are respectively connected to a lower end of the handle and the transmission device. The swinging of the handles drives the foot pedal rods and the transmission device rotates. The positions of elliptical trace of the pedal rods are adjusted by adjusting the upper tube upward or downward relative to the lower tube so as to simulate uphill hiking and downhill hiking and exercise different parts of muscles.

Claims

1. An elliptical exerciser comprising:

a base putting on the floor;

a body having a casing and a transmission device connected to a rear end there of the body and exposed outside the casing, the transmission device being operated as circular movement;

an upright post including an upper tube and a lower tube in which the upper tube retractably inserted for adjusting the height, the lower end of the lower tube fixed to the base;

two handles respectively pivotably connected to two sides of the upper tube at two respective mediate portions of the two handles, and

two foot pedal rods each having a front end pivotably connected to a lower end of respective one of the two handles and a rear end of each of the two foot pedal rods respectively connected to the transmission device, a foot pedal board provided on each of the two foot pedal rods and moving along in an elliptical trace when the two handles are pivotably swung, positions of the elliptical trace being changed when the upper tube is adjusted relative to the lower tube.

2. The elliptical exerciser as claimed in claim 1, wherein a positioning device is connected to the upper tube or the lower tube so as to position the upper tube relative to the lower tube.

3. The elliptical exerciser as claimed in claim 2, wherein the positioning device includes a retractable pin connected to the lower tube and the upper tube includes a plurality of holes, the pin engaged with one of the holes in the upper tube.

4. The elliptical exerciser as claimed in claim 3, wherein a spring is mounted to the pin which is pulled outward and disengaged from the hole so that the upper tube is freely moved relative to the lower tube till the pin is engaged with another one of the holes in the upper tube.

5. The elliptical exerciser as claimed in claim 1, wherein the transmission device includes two disks which are connected at two respective centers thereof, the two rear ends of the two foot pedal rods respectively connected to the two disks.

6. The elliptical exerciser as claimed in claim 1, wherein the front end of each of the foot pedal rods tilts upward when the upper tube is extended upward.

7. The elliptical exerciser as claimed in claim 1, wherein the front end of each of the foot pedal rods tilts downward when the upper tube is retracted into the lower tube.

8. The elliptical exerciser as claimed in claim 1, wherein the base includes two transverse bars connected to two ends thereof.

9. The elliptical exerciser as claimed in claim 1, the upper tube includes two extension rods and the two respective mediate portions of the two handles are connected to the two extension rods.
