Claim:
1. A jack for lifting wheeled mobile devices consisting of: a two wheeled framework; said framework including: a ratcheting mechanism having said center bar receivable therein, said ratcheting mechanism having a cross bar mounted on said framework secured to said ratchet housing such that as the ratchet mechanism moves up and down on the center bar, said cross bar having a base bar mounted at the bottom of said framework extending in the direction of said cradles, said base bar having wherein said base bar comprises a pair of pivotally connected sections, one section terminating in said cross bar and pivotable upwardly towards said vertically extending bars to a position generally parallel to said vertically extending bars and locked to said other section for storing the same, and the spaced upright vertically extending bars including locks for operation with the cross bar mounted on the framework whereby the cross bar is lockable to the vertically extending fixed bars to prevent movement downwardly of the cross bar mounted on the framework, wherein the locks include a pair of brackets, each bracket being separated from the other without an intervening connector and being directly connected with the cross bar, and each bracket being directed from the cross bar rearwardly and upwardly at an angle to a position behind the vertical bars such that an end of the bracket behind the vertical bar includes a transverse roller for engaging behind the bar and a lower-positioned roller in front of the bar for engaging the vertically extending fixed height bars, including spaced apertures in the fixed height vertical bars, and pins for extending through the apertures below the brackets and whereby the brackets rest on the pins thereby to secure the brackets from downward movement, and wherein the pins are selectively removable from the apertures and are selectively locatable in a selected spaced aperture thereby to secure the cross bar in a selected height position.
