Abstract

A height-adjustable aerobic step is disclosed. The lower half of each supporting leg is disposed with a first positioning portion having two parallel first lateral plates and at least one first seizure portion on at least one first lateral plates, and the upper half of one extending leg is disposed with a second positioning portion which pivotally connects to the first positioning portion for the extending leg to be folded inwardly, or unfolded into a straight line with the supporting leg to elevate the height of rectangular step platform. The second positioning portion has two parallel second lateral plates which are respectively corresponding to and placed adjacent to the two first lateral plates, and sides of at least second lateral plates are disposed with at least one second seizure portion corresponding to the first seizure portion for fixing the position of the extending leg at different angles.

Claims

1. A height-adjustable aerobic step comprising a rectangular step platform with two opposite ends in a length direction thereof and two supporting legs respectively downwardly extending from a bottom surface of each end, characterized in that:

a lower half of each supporting leg is disposed with a first positioning portion having two parallel first lateral plates with a side of at least one of them being disposed with at least one first seizure portion, and an upper half of one extending leg is disposed with a second positioning portion which pivotally connecting to the first positioning portion for the extending leg to be folded inwardly relative to the supporting leg such that a bottom surface of the supporting leg is at a top surface of the extending leg when the supporting leg and the extending leg are unfolded into a straight line, and the second positioning portion has two parallel second lateral plates which are respectively corresponding to and placed adjacent to the two first lateral plates, and a side of at least one of the second lateral plates is disposed with at least one second seizure portion for corresponding to the first seizure portion to limit its position.

2. The height-adjustable aerobic step according to claim 1, wherein the first positioning portion includes two parallel first lateral plates with a receiving space therebetween.

3. The height-adjustable aerobic step according to claim 2, wherein the second positioning portion includes a protrusion portion upwardly extending from the top surface of the extending leg, and the two parallel second lateral plates are respectively formed at two sides of the protrusion portion, and the protrusion portion is pivotally located into the receiving space of the two first lateral plates.

4. The height-adjustable aerobic step according to claim 1, wherein one of the correspondingly and adjacently placed first and second lateral plates is a bendable flexible plate.

5. The height-adjustable aerobic step according to claim 4, wherein the second seizure portion is at least one bump and the first seizure portion is at least one hole corresponding to the second seizure portion, and two first seizure portions are respectively provided on the first lateral plates at a substantially vertical angle.

6. The height-adjustable aerobic step according to claim 4, wherein the first seizure portion is at least one bump and the second seizure portion is at least one hole corresponding to the first seizure portion, and two second seizure portions are respectively provided on the second lateral plates at a substantially vertical angle.

7. The height-adjustable aerobic step according to claim 1, wherein the rectangular step platform includes a first plate body, a second plate body and a connecting member, and the two supporting legs respectively downwardly extending from one end of the first plate body and one end of the second plate body while the other end of the first plate body is horizontally opposed to the other end of the second plate body, and the connecting member respectively connects to the bottom surface of the first and second plate body.

8. The height-adjustable aerobic step according to claim 7, wherein the bottom surface of the first plate body is disposed with at least one first elongated recess and the bottom surface of the second plate body is disposed with at least one second elongated recess correspondingly communicating with the first elongated recess, and the connecting member includes at least one elongated rod which is correspondingly received in the mutually communicated first and second elongated recesses and respectively locked to the bottom surfaces of the first and second plate bodies.
