<p>The support leg for a gymnastic frame allows it to be inclined to the ground and the separation of the feet to be adjusted. The leg has a main tube, articulated under the frame at one extremity and joined to a horizontal tube, with an anti-slip cover and rollers, at the other extremity. The main tube slides in a tube and a stud on a foot can engage in holes in this tube to lock it in place. A second tube, articulated under the appts., is articulated to the sliding tube.</p> |
