ABSTRACT:
A ratchet jack stand assembly intended for supporting a raised load is formed entirely of stamped steel components and is free of any spring-biased members. The assembly includes a base, a housing welded to the base, an elongated post slideably supported by the housing in an upright position, and a gravity-biased handle pivotally mounted on the housing. A plurality of inclined, longitudinally spaced notches are formed in the post and a saddle is welded to its upper end. A pair of inclined, horizontally spaced and aligned slots are formed in the housing. The gravity-biased handle has spaced upper and lower pins attached thereto, and is pivotally mounted on the housing by the lower pin. The upper pin of the handle is positioned and adapted to slideably move along the aligned housing slots to a locked position as the handle moves to its biased position when a selected one of the post notches is manually aligned with the housing slots, for positive locking engagement with the post notch to adjustably support the post at a predetermined height for supporting a raised load.
