The disclosure and prior art relate to jacking assemblies and more particularly pertain to a new jacking assembly for selectively raising a wheel of a vehicle for changing a tire.
An embodiment of the disclosure meets the needs presented above by generally comprising a plurality of cylinders and an actuator. Each cylinder is configured to be coupled to a frame of a vehicle proximate to a respective wheel of the vehicle. The cylinder comprises a plurality of nested sections so that the cylinder is selectively extensible. The actuator is configured to be coupled to the vehicle and to be operationally coupled to an electrical circuit of the vehicle. The actuator is operationally coupled to the plurality of cylinders so that the actuator is positioned to selectively actuate a respective cylinder to extend the respective cylinder from the frame of the vehicle so that the respective cylinder contacts a surface. The respective cylinder thus is configured to raise an associated wheel of the vehicle from the surface, allowing a tire of the wheel to be changed.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
Each cylinder 12 comprises a first plate 24 that is coupled to an outermost nested section 26, as shown in
A second plate 30 is coupled to an innermost nested section 32 so that the plurality of nested sections 22 extends perpendicularly from the second plate 30. The second plate 30 is configured to stabilize the cylinder 12 on a surface when the cylinder 12 is extended between the frame 16 of the vehicle 18 and the surface. The second plate 30 is circularly shaped.
The actuator 14 is configured to be coupled to the vehicle 18 and to be operationally coupled to an electrical circuit 34 of the vehicle 18. The actuator 14 is operationally coupled to the plurality of cylinders 12 so that the actuator 14 is positioned to selectively actuate a respective cylinder 12 to extend the respective cylinder 12 from the frame 16 of the vehicle 18 so that the respective cylinder 12 contacts a surface. The respective cylinder 12 thus is configured to raise an associated wheel 20 of the vehicle 18 from the surface, as shown in
The actuator 14 comprises a hydraulic motor 38 and a manifold 40, as shown in
The assembly 10 also comprises a reservoir 42 that is configured to be coupled to the vehicle 18. The reservoir 42 is configured to position hydraulic fluid. The reservoir 42 is operationally coupled to the hydraulic motor 38 so that the reservoir 42 is in fluidic communication with the hydraulic motor 38. The reservoir 42 is configured to supply the hydraulic fluid to the hydraulic motor 38. Each hydraulic line 68 of a plurality of hydraulic lines 68 is operationally engaged to and extends between the manifold 40 and a respective cylinder 12.
A controller 44 is configured to be coupled to an interior surface of the vehicle 18. The controller 44 is operationally couplable to an electrical circuit of the vehicle 18. The controller 44 is operationally coupled to the actuator 14 so that the controller 44 is positioned to direct the actuator 14 to selectively actuate a respective cylinder 12 to extend the respective cylinder 12 from the frame 16 of the vehicle 18 so that the respective cylinder 12 contacts the surface to raise an associated wheel 20 of the vehicle 18 from the surface.
The controller 44 comprises a housing 46 that defines an interior space 48. A microprocessor 50 is coupled to the housing 46 and is positioned in the interior space 48. A plurality of switches 52, a power control 54, a gauge 56, and a plurality of indicia 58 are coupled to a front 64 of the housing 46, as shown in
The gauge 56 also is operationally coupled to the hydraulic motor 38. The gauge 56 is pressure type so that the gauge 56 is configured to measure and display a pressure of the hydraulic fluid.
The indicia 58 are configured to indicate a function and status of each of the switches 52 and the power control 54. For example, each switch 52 may be labeled as to its associated wheel 20 of the vehicle and have an “Up” and a “Down” notation corresponding to the status of the cylinder 12 associated with the associated wheel 20.
A panel 60 is hingedly coupled to an upper edge 62 of the front 64 of the housing 46, as shown in
The controller 44 is configured to be coupled to a dash of the vehicle 18, as shown in
In use, when a tire 36 of a respective wheel 20 of a vehicle 18 needs to be changed, the user lifts the panel 60 to expose the front 64 of the controller 44. The power control 54 is switched on, and the switch 52 corresponding the respective wheel 20 is switched so that the microprocessor 50 directs the actuator 14 to actuate an associated cylinder 12 to extend the associated cylinder 12 from the frame 16 of the vehicle 18 so that the associated cylinder 12 contacts the surface to raise the respective wheel 20 of the vehicle 18 from the surface.
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 elements is present, unless the context clearly requires that there be only one of the elements.
