Abstract
One jack stand includes a stand assembly having a base and a tubular receiving member extending upwardly therefrom. A latch extends from the tubular member. A support bar having upper and lower ends is telescopically housed in a cavity of the tubular member. First and second sides of the bar each have multiple embedded slots. A third side of the bar has multiple holes with angled surfaces such that positioning the latch in any of the holes restricts the bar from moving upwardly yet allows the bar to move downwardly. An automatic lifting device is at least partially inside the cavity and imparts an upward force upon the bar. A stopper selectively interacts with the stand assembly and the bar to restrict the bar from moving downwardly, yet allows the bar to move upwardly. The stopper passes at least partially inside two of the slots to interact with the bar.
