Abstract

A vehicle leveling system includes a jack adapted to be mounted to a vehicle frame without modifying the vehicle frame. In a particular embodiment, the jack includes a first bracket adapted to urge against the bottom and side surfaces of a member of the frame and configured to be fastened to a member of the frame through a manufacturer-provided aperture in the frame. The jack additionally includes a second bracket to couple the first bracket to the jack. In a more particular embodiment, the first bracket includes a horizontal adjustment feature, and the second bracket includes a vertical adjustment feature.

Claims (57)

1. A vehicle comprising:

a vehicle frame including a first frame rail, said first frame rail including a first manufacturer-provided aperture formed in said first frame rail, said first frame rail including an open end;

a frame attachment including an aperture, said frame attachment being coupled to said open end of said frame rail;

a first jack extendable between a stowed position and a deployed position, said first jack having an upper portion and a lower portion extendable with respect to said upper portion;

a first frame engaging bracket coupled to said upper portion of said first jack, said first frame engaging bracket including a side surface facing a side surface of said first frame rail and defining a first fastening aperture aligned with said first manufacturer-provided aperture in said first frame rail and said aperture of said frame attachment; and

a fastener securing said first frame engaging bracket to said first frame rail, said fastener being disposed through said first fastening aperture of said first frame engaging bracket, said first manufacturer-provided aperture in said first frame rail, and said aperture of said frame attachment;

wherein: said first frame engaging bracket includes an upright portion, a first side wall, and a second side wall, said upright portion having an interior surface;

said upright portion includes a first side edge and a second side edge, the first side wall extending outwardly from said first side edge and having a first surface, said second side wall extending outwardly from said second side edge and having a second surface; and said first surface, said second surface, and said interior surface define a receiving space for receiving at least a portion of said upper portion of said first jack;

said first jack welded in position with respect to said receiving space.

2. The vehicle of claim 1 , wherein:

said side surface of said first frame engaging bracket defines at least one additional fastening aperture spaced apart from said first fastening aperture;

said first frame rail includes at least one additional manufacturer-provided aperture spaced apart from said first manufacturer-provided aperture;

said frame attachment includes at least one additional aperture:

said at least one additional fastening aperture, said at least one additional aperture of said frame attachment, and said at least one additional manufacturer-provided aperture are aligned with respect to one another; and

said vehicle includes a second fastener disposed through said at least one additional fastening aperture, said at least one additional aperture of said frame attachment, and said at least one additional manufacturer-provided aperture, thereby preventing rotation of said first frame engaging bracket with respect to said first frame rail.

3. The vehicle of claim 1 , wherein said first fastener is a nut and bolt.

4. The vehicle of claim 1 , wherein:

said first frame rail includes a hollow body having a first side wall and a second sidewall spaced apart from said first sidewall, said first side wall defining said first manufacturer-provided aperture; and

said first fastener is disposed through at least said first side wall via said manufacturer-provided aperture.

5. The vehicle of claim 4 , wherein:

said second sidewall defines a second manufacturer-provided aperture aligned with said first manufacturer-provided aperture; and

said first fastener is disposed through said second sidewall via said second manufacturer-provided aperture.

6. The vehicle of claim 1 , wherein said upper portion of said first jack is permanently affixed to said first frame engaging bracket.

7. The vehicle of claim 6 , wherein said upper portion of said first jack is welded to said first frame engaging bracket.

8. The vehicle of claim 7 , wherein:

said first side wall defines said first fastening aperture;

said second side wall defines a second fastening aperture; and

said first fastening aperture, said second fastening aperture, and said first manufacturer-provided aperture are aligned along a common axis.

9. The vehicle of claim 8 , wherein said fastener is disposed through said manufacturer-provided aperture, said aperture of said frame attachment, said first fastening aperture, and said second fastening aperture.

10. The vehicle of claim 9 , wherein:

said first side wall defines at least a first additional fastening aperture spaced apart from said first fastening aperture;

said second side wall defines at least a second additional fastening aperture spaced apart from said second fastening aperture;

said frame attachment defines at least one additional aperture;

said first frame rail defines at least one additional manufacturer-provided aperture; and

said vehicle includes a second fastener passing through said first additional fastening aperture, said second additional fastening aperture, said additional aperture of said frame attachment, and said additional manufacturer-provided aperture.

11. The vehicle of claim 10 , wherein said first side wall defines exactly two fastening apertures, and said second side wall defines exactly two fastening apertures.

12. The vehicle of claim 9 , wherein said fastener extends through said receiving space between said upright portion of said first frame engaging bracket and said upper portion of said first jack.

13. The vehicle of claim 1 , wherein said first side wall includes said side facing surface that is facing said side surface of said first frame rail.

14. The vehicle of claim 1 , wherein said frame is a motorized vehicle frame.

15. A vehicle jack comprising:

an upper portion;

a lower portion extendable with respect to said upper portion; and

a frame engaging bracket including an upright portion, a first side wall, and a second side wall, said upright portion having an interior surface; and wherein

said upright portion includes a first side edge and a second side edge, the first side wall extending outwardly from said first side edge and having a first surface, said second side wall extending outwardly from said second side edge and having a second surface;

said first surface, said second surface, and said interior surface defining a receiving space, at least a portion of said upper portion of said first jack being welded in position in said receiving space; and

said first side wall includes an outer surface disposed to abut a side surface of a first frame rail and defines a first fastening aperture disposed to be aligned with a first manufacturer-provided aperture formed in said first frame rail; and

whereby said upper portion of said first jack can be rigidly fixed to said first frame rail without modifying said first frame rail.

16. The vehicle jack of claim 15 , wherein:

said second side wall defines a second fastening aperture;

said first fastening aperture and said second fastening aperture are disposed to facilitate alignment with said first manufacturer-provided aperture along a common axis; and

said first fastening aperture and said second fastening aperture can be disposed relative to said first manufacturer-provided aperture to receive a common fastener through said first fastening aperture, said second fastening aperture, and said manufacturer-provided aperture.

17. The vehicle jack of claim 16 , wherein:

said first side wall defines at least a first additional fastening aperture spaced apart from said first fastening aperture;

said second side wall defines at least a second additional fastening aperture spaced apart from said second fastening aperture;

said first additional fastening aperture and said second additional fastening aperture are disposed to facilitate alignment with an additional manufacturer-provided aperture of said vehicle frame along a second common axis; and

said first additional fastening aperture and said second additional fastening can be disposed relative to said additional manufacturer-provided aperture to receive a second common fastener through said first additional fastening aperture, said second additional fastening aperture, and said manufacturer-provided aperture.

18. The vehicle jack of claim 17 , wherein said first side wall defines exactly two fastening apertures, and said second side wall defines exactly two fastening apertures.
