## Abstract

A stepping exerciser includes a base frame having a first end portion, a second end portion, a first side wall, and a second side wall. A supporting handle has a lower end portion mounted on the first end portion of the base frame in an inclined manner, and an upper end portion with a handgrip mounted thereon. A driving axle is rotatably mounted on the second end portion of the base frame and has a first end and a second end extending through the first and the second side wall of the base frame respectively. A first stepping member has a mediate portion fixedly mounted on the first end of the driving axle. A second stepping member is disposed in an inclined manner with the first stepping member and has a mediate portion fixedly mounted on the second end of the driving axle. A tension adjusting mechanism is mounted in the base frame and is engaged with the driving axle for damping a rotation of the driving axle.

## Claims

### Claim 1

A stepping exerciser comprising:
a base frame (11) having a first end portion, a second end portion, a first side wall, and a second side wall;
a supporting handle (12) having a lower end portion mounted on the first end portion of said base frame (11) in an inclined manner, and an upper end portion with a handgrip (122) mounted thereon;
a driving axle (15) rotatably mounted on said second end portion of said base frame (11) and having a first end and a second end extending through said first and said second side wall of said base frame (11) respectively;
a first stepping member including a first elongate beam (16) having a mediate portion fixedly mounted on said first end of said driving axle (15), said first elongate beam (16) having two distal ends, each end thereof including a plurality of adjusting holes (166);
two first pedals (162) each including a stub (164) pivotally mounted in a corresponding one of said adjusting holes (166) of each of said two distal ends of said first elongate beam (16);
a second stepping member disposed in an inclined manner with said first stepping member and including a second elongate beam (17) having a mediate portion fixedly mounted on said second end of said driving axis (15), said second elongate beam (17) having two distal ends, each end thereof including a second pedal (172) mounted thereon;
a tension adjusting mechanism (30) mounted in said base frame (11) and engaged with said driving axle (15) for damping a rotation of said driving axle (15); and
resistance means (34) for creating a damping action complementing said tension adjusting mechanism (30).

### Claim 2 (depends on 1)

The stepping exerciser in accordance with claim 1, wherein each of the two distal ends of said second elongate beam (17) includes a plurality of adjusting holes (176), and said second pedal (172) includes a stub (174) pivotally mounted in a corresponding one of said adjusting holes (176).
