Each jack stand includes a rectangular bottom plate having a pair of rectangular openings therein. The rack has a rectangular platform having a lateral loading side, a width a little larger than the jack-stand-length, and a length equal to a multiple of the jack stand widths. A plurality of L-shaped fingers are located on the platform at points corresponding to the opening in the bottom plate, and extends upwardly and laterally toward the non loading side of the platform. Each finger has a rectangular upper surface thereon having a width and length slightly smaller than the width and length of the openings in the bottom plates; and creates an opening between the platform and the finger that is slightly greater that the thickness of the bottom plates of the jack stands. Each finger is for receiving one of the rectangular openings of the respective bottom plate onto the platform; and a lateral movement of the bottom plate in the direction of the lateral loading side of the platform is for locking the bottom plate under the respective finger and onto the platform of the mobile rack. The rack includes a pair of wheels attached to the rearward end of the platform, so that the platform engages the horizontal surface when the forward end of the platform is horizontal, and so that the pair of wheels engage the horizontal surface when the forward end of the platform is lifted at an acute angle. |

1. A mobile rack for transporting two or more jack stands thereon, wherein each jack stand includes a rectangular bottom plate having a front end, a back end, a lateral width W, a longitudinal length L and a thickness, with the bottom plate having a pair of rectangular openings therein, with each opening having a width and a length and located at about the lateral center ½W of the bottom plate width, and with one opening at about ¾L of the bottom plate length from the back end thereof, and with the other opening at about ¾L of the bottom plate length from the front end thereof, wherein the rack comprises:
a rectangular platform having a rearward end, a forward end, a lateral loading and unloading side, a lateral non-loading side, a width a little larger than the jack-stand-length, and having a length equal to a multiple of about the jack stand widths; a plurality of L-shaped fingers located on said platform at points corresponding to the centers of the jack-stand-widths of adjacent respective jack stands, and corresponding to about ¾L of the jack-stand length, from the lateral loading side of said platform, each said finger extending upwardly and laterally toward the non loading side of said platform and has a rectangular upper surface thereon having a width and length slightly smaller than the width and length of the openings in the bottom plates of the jack stands, with each finger creating an opening between the platform and the upper rectangular surface thereof that is slightly greater that the thickness of the bottom plates of the jack stands; wherein, each said finger is for receiving the rectangular opening that is ¾L of the length from the back end of the respective bottom plate of the jack stand onto said platform, and whereby lateral movement of the bottom plate in the direction of the lateral loading side of said platform is for locking the respective jack stand bottom plate under said respective finger and onto said platform of said mobile rack; a pair of vertical flanges having lateral axels therein with wheels thereon, attached to each lateral side at the rearward end of said platform, and extending upwardly and rearwardly, so that said platform engages the horizontal surface when the forward end of said platform is horizontal, and so that said pair of wheels engage the horizontal surface when the forward end of said platform is lifted at an acute angle; and handle means for lifting the forward end of said platform at an acute angle for transporting the rack, and for lowering the rack to the horizontal surface for loading and unloading the respective jack stand. |
