Abstract:
A vehicular jack system comprising, in combination:a mounting bracket including a planar rectangular horizontal plate with a periphery defined by a short inboard edge, a short outboard edge and a pair of elongated parallel side edges, the mounting bracket further including a pair of vertical plates including a first vertical plate integrally coupled along the inboard edge of the horizontal plate and extending upwardly therefrom in perpendicular relationship therewith and a second vertical plate integrally coupled along a center line of the horizontal plate and extending upwardly therefrom in perpendicular relationship therewith, thereby defining a slot for receiving a longitudinal frame bar of a vehicle, wherein the mounting bracket is permanently attached to the frame bar via a plurality of screws;a jack assembly including a vertically oriented cylindrical tube mounted to the horizontal plate of the mounting bracket between the outboard edge and the center line thereof such that the cylindrical tube extends both above and below the horizontal plate of the mounting bracket to define an upper extent and a lower extent, the jack assembly further including an elevation cylinder slidably situated within the cylindrical tube and having a planar square base mounted to a lower end thereof, the elevation cylinder having a plurality of vertically spaced notches formed therein, the jack assembly including a control mechanism including a housing coupled to the lower extent of the cylindrical tube and extending radially therefrom past the outboard edge of the horizontal plate of the mounting bracket, the housing having an open top and an upwardly extending outboard lip, the control mechanism further including a sleeve with an inboard end pivotally coupled within the housing about a horizontal axis wherein the sleeve has a vertical tab coupled to a bottom end thereof with a notch formed therein for removably receiving the upwardly extending outboard lip when in a lowered orientation, whereby the elevation cylinder is adapted to raise and lower upon the reciprocation of the sleeve thereby elevating the vehicle;a jack arm having an L-shaped configuration with a first end with a tapered configuration and a second end with a socket mounted thereon, wherein the first end is adapted to be removably situated within an outboard end of the sleeve for manually reciprocating the same;a storage locking assembly including a first pair of vertical bores formed in the horizontal plate of the mounting bracket adjacent ends of the outboard edge thereof, a second pair of bores formed in the base of the elevation cylinder of the jack assembly adjacent ends of an outboard edge thereof, and a pair of bolts each having a length about equal to a height of the bottom extent of the elevation cylinder of the jack assembly for being coupled within the first and second pair of bores for maintaining the elevation cylinder in an upwardly extended orientation for storage purposes; anda deployed locking assembly including a first aperture formed in the elevation cylinder of the jack assembly at a top end thereof and a second aperture formed in the upper extent of cylindrical tube of the jack assembly adjacent to a top end thereof, a quick release pin removably situated within the first and second apertures for maintaining the elevation cylinder in a downwardly extended orientation during deployment.
