Height adjustable aerobic step
First Claim
1. A height-adjustable aerobic step comprising a rectangular step platform with two opposite ends in a length direction thereof and two supporting legs, each of the two supporting legs extending downwardly respectively from a bottom surface of each of the two opposite ends,wherein a lower half of each of the two supporting legs are disposed with a first positioning portion having two parallel first lateral plates with a side of each of the two parallel first lateral plates being disposed with two first seizure portions, an upper half of each of two extending legs is disposed with a second positioning portion pivotally connecting to the first positioning portion of each of the two supporting legs for each of the two extending legs configured to be folded inwardly relative to the two supporting legs such that a bottom surface of the two supporting legs are at a top surface of the two extending legs when the two supporting legs and the two extending legs are unfolded into a straight line, the second positioning portion has two parallel second lateral plates which are respectively corresponding to and placed adjacent to the two parallel first lateral plates, and a side of each of the two parallel second lateral plates is disposed with two second seizure portions for corresponding to the two first seizure portion and limiting a position of the two first seizure portion;
- andwherein the two parallel first lateral plates and the two parallel second lateral plates are bendable and flexible, so as to allow one of the second lateral plate to slide on a corresponding one of the first lateral plates.

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.
