With reference now to the drawings, and in particular to FIGS. 1 through 4 thereof, a new vehicle jack embodying the principles and concepts of an embodiment of the disclosure and generally designated by the reference numeral 10 will be described.
As best illustrated in FIGS. 1 through 4, the rolling vehicle jack 10 generally comprises a base 12. The base 12 is substantially rectangularly box shaped and defines an internal space 14. A spring 16 is coupled to a top 18 of the base 12 and is positioned in the internal space 14 of the base 12. A penetration 20 is positioned through a bottom 22 of the base 12. The penetration 20 is circular.
A sphere 24 is rollably coupled to the spring 16. The sphere 24 is selectively extensible through the penetration 20. The sphere 24 is positioned on the spring 16 such that the sphere 24 is configured to roll on a surface such that the base 12 is reversibly positionable under a vehicle.
A bushing 26 is coupled to the base 12 around a circumference 28 of the penetration 20. The bushing 26 is positioned on the base 12 such that the sphere 24 is positioned to roll over the bushing 26 as the sphere 24 extends from and retracts into the internal space 14 through the penetration 20.
A lift 30 is coupled to the top 18 of the base 12. The lift 30 is selectively extensible from the base 12. The lift 30 is tubular. In one embodiment, the lift 30 is substantially circular when viewed longitudinally. The lift 30 comprises a plurality of nested sections 32. In one embodiment, the plurality of nested sections 32 comprises four nested sections 32.
An actuator 34 is coupled to the base 12 and is positioned in the internal space 14. The actuator 34 is operationally coupled to the lift 30. The lift 30 is positioned on the base 12 such that the actuator 34 is positioned to motivate the lift 30 to extend vertically from the base 12, wherein the sphere 24 is retracted into the base 12. A vehicle that is positioned above the lift 30 is raised and is positioned for maintenance, such as changing of tires, wheels and tracks. In one embodiment, the actuator 34 is hydraulic. In another embodiment. The actuator 34 is pneumatic.
A plurality of cranks 36 pivotally is coupled to the top 18 of the base 12. The cranks 36 are tubular. Each crank 36 is operationally coupled to the actuator 34. The cranks 36 are positioned on the base 12 such that the cranks 36 are positioned to motivate the actuator 34 to extend the lift 30 from the base 12. In one embodiment, the plurality of cranks 36 comprises four cranks 36 that are positioned evenly around and proximate to the lift 30.
A plate 38 is coupled to an upper end 68 of the lift 30. The plate 38 is positioned on the lift 30 such that the plate 38 is configured to abut an underside of the vehicle as the lift 30 is extended. In one embodiment, the plate 38 is circular.
In one embodiment, an orifice 40 is centrally positioned through the plate 38. In this embodiment, the jack 10 comprises a plurality of attachments 42. Each attachment 42 comprises a neck 44 and a head 46. The neck 44 is complementary to the orifice 40 such that the neck 44 is positioned for selective insertion into the orifice 40 to position the head 46 above the plate 38. The head 46 is configured to abut the underside of the vehicle as the lift 30 is extended. In another embodiment, the plurality of attachments 42 comprises a first insert 48, a second insert 50 and a third insert 52. The head 46 of the first insert 48 is ball-shaped. The head 46 of the second insert 50 is Y-shaped. The head 46 of the third insert 52 is studded.
A plurality of feet 54 is coupled to the bottom 22 of the base 12 proximate to a perimeter 56 of the base 12. The feet 54 are self-leveling. The feet 54 are positioned on the base 12 such that the feet 54 are configured to contact the surface as the sphere 24 is retracted into the base 12. In one embodiment, the plurality of feet 54 comprises feet 54 is positioned singly proximate to corners 58 of the base 12.
The jack 10 comprises a handle 60 that is complementary to the cranks 36. The handle 60 is selectively insertable into a respective crank 36. The handle 60 is positioned to insert into the respective crank 36 such that the handle 60 is configured to motivate the respective crank 36 to motivate the actuator 34. In one embodiment, the handle 60 comprises a plurality of connectable sections 62. Respective connectable sections 62 are selectively couplable such that the handle 60 is length adjustable. In another embodiment, the plurality of connectable sections 62 comprises three connectable sections 62.
A grip 64 is coupled proximate to an end of the handle 60. The grip 64 is positioned on the handle 60 such that the grip 64 is configured to be grasped in a hand of a user.
A hook 66 is coupled to the handle 60. The hook 66 is positioned on the handle 60 such that the hook 66 is positioned to couple to the base 12 such that the base 12 is maneuverable upon the sphere 24 for reversible positioning under the vehicle.
In use, the sphere 24 is positioned on the spring 16 such that the sphere 24 is configured to roll on a surface to reversibly position the base 12 is under a vehicle. The handle 60 is positioned to insert into a respective crank 30. The handle 60 is configured to motivate the respective crank 36 to motivate the actuator 34 to motivate the lift 30 to extend vertically from the base 12, wherein the sphere 24 is retracted into the base 12. A vehicle that is positioned above the lift 30 is raised and is positioned for maintenance, such as changing of tires, wheels and tracks.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
