Abstract

An exercise apparatus having a pulley, a pair of stabilizing assemblies each configured to couple a front portion of a respective pedal element to each side of the pulley, a looped belt configured to couple the pulley to a resistance assembly, a tension stabilizer configured to maintain a tension of the looped belt on the pulley, and the resistance assembly configured to assert an adjustable resistance to the pedal elements through the looped belt. The exercise apparatus also comprises a resistance band extension for performing additional exercise using resistance bands and a transport mechanism for transporting the exercise apparatus and securing the exercise apparatus to a chair wheel or other structure during exercise.

Claims

1. A portable exercise apparatus comprising:

a chassis;

a base plate coupled to a rear side of the chassis;

a chassis front bar coupled to a front side of the chassis;

a first attachment point coupled to the chassis front bar adjacent a left side of the chassis;

a second attachment point coupled to the chassis front bar adjacent a right side of the chassis;

a first pulley coupled to the base plate in front of the front side of the chassis on a left side of the base plate;

a second pulley coupled to the base plate in front of the front side of the chassis on a right side of the base plate;

a first pedal rotatably mounted to the left side of the chassis; and

a second pedal rotatably mounted to the right side of the chassis, wherein the first pulley is coupled to the base plate to a right side of the first pedal so as not to interfere with rotational motion of the first pedal;

a first resistance band, wherein a first end of the first resistance band is coupled to the first attachment point and a second end of the first resistance band is routed through the first pulley, and wherein the second end of the first resistance band is coupled to a first handle; and

2. The portable exercise apparatus according to claim 1, further comprising:

a holder coupled to the base plate between the first pulley and the second pulley.

3. The portable exercise apparatus according to claim 2, wherein the holder comprises:

a first channel configured to retain the first handle in a snap-fit connection; and

a second channel configured to retain the second handle in a snap-fit connection.

4. The portable exercise apparatus according to claim 1, wherein the second pulley is coupled to the base plate to a left side of the second pedal so as not to interfere with rotational motion of the second pedal.

5. The portable exercise apparatus according to claim 1, wherein the first end of the first resistance band is coupled to the first attachment point via a clip.

6. The portable exercise apparatus according to claim 1, wherein the first attachment point is a circular ring.

7. The portable exercise apparatus according to claim 1, wherein the second end of the first resistance band is coupled to the first handle via a detachable connection.
