Abstract:
1. A jack assembly, in particular a jack assembly for a motor vehicle comprising: first and second upper brackets forming elongated downwardly open channels with spaced opposing sides, said first and second upper brackets are pivotally connected to a support member and tapered for strength, said first and upper brackets include at least one strengthening bead having rolled edges extending longitudinally along said spaced opposing sides of said first and second upper brackets respectively for strengthening said first and second upper brackets; an inwardly extending flange for strength formed along a longitudinal outer edge of said spaced opposed sides of said first and second upper brackets respectively and forming a plurality of teeth at an upper end of said first and second upper brackets respectively that are in mesh with one another; first and second lower brackets forming elongated upwardly open channels with upwardly extending spaced opposing sides, said first and second lower brackets are tapered for strength and include at least one strengthening flange; said at least one strengthening flange extending along the entire longitudinal length of an upwardly located outer edge of said opposing sides of said first and second lower brackets respectively for strengthening said first and second lower brackets, wherein said at least one strengthening flange is configured to extend outwardly along said outer edges and form a plurality of teeth at a lower end of said first and second lower brackets respectively that are in mesh with one another, and configured to substantially encircle the top of a cap of a first and second side pins respectively to provide strength at joints where said first and second side pin pivotally connect said first and second lower brackets and said first and second upper brackets respectively; raised bosses formed on said spaced opposing sides and located at lower ends of said first and second lower brackets, wherein said raised bosses are shaped and configured to receive a first and second lower pin through an aperture respectively to pivotally connect said first and second lower brackets to a jack base configured to rest on a ground surface as at least one vehicle wheel is lifted from said ground surface; a rotatable threaded rod extending through said first side pin and said second side pin to cause said first upper bracket to pivot relative to said support member and said first lower bracket, said second upper bracket to pivot relative to said support member and said second lower bracket, and said support member to move either away from said jack base or toward said jack base when said threaded rod is rotated; and an enclosed keyhole orifice disposed on said jack base for mounting to said motor vehicle, wherein said enclosed keyhole orifice includes a larger entry portion and a narrower retention portion adapted for receiving a narrower shaft portion and a wider end portion of a vehicle mounting structure through said larger entry portion and retaining said narrower shaft portion within said narrower retention portion of said enclosed keyhole orifice to hold said jack assembly in a stored position by friction.
