Abstract
A telescoping jack stand made of stamped metal parts with a pair of angularly extending legs which are pivotally mounted with respect to each other. The legs define an aperture between the legs with inwardly extending integral teeth. A central column member includes matching teeth and corresponding in shape and dimension with the aperture between the two legs. The central column includes recesses corresponding to the integral teeth of the legs. The legs are pivoted with respect to each other so that upon engagement of the teeth with the recesses in the column, additional load tends to pivot the teeth into greater engagement with the column and provide improved stability.
