In the shown embodiment, a plurality of recesses 26 are disposed adjacent to each of the plurality of jack assemblies 12, wherein each of the plurality of recesses 26 are dimensioned to receive a jack assembly 12 therein. In this manner, the plurality of jack assemblies 12 are stored in a low-profile manner when not in use, so as not to interfere with the operation of the vehicle while in use. In the illustrated embodiment, the integrated jack system for a vehicle 11 further comprises a hydraulic tank 25 centrally disposed within the vehicle frame 13, such that the weight of the hydraulic tank 25 is evenly distributed across the vehicle frame 13. The hydraulic tank 25 is operably connected to each of the plurality of jack assemblies 12 to selectively extend and retract the plurality of jack assemblies 12 via hydraulic actuation. In other embodiments, each jack of the plurality of jack assemblies 12 is separately connected to a distinct localized hydraulic tank disposed adjacent to each jack of the plurality of jack assemblies 12, such that each jack is independently operable. In this manner, should one localized hydraulic tank be damaged, such as during a vehicular accident, the remaining jacks of the plurality of hydraulic jacks 12 would retain functionality. In alternate embodiments, the plurality of jack assemblies 12 are actuated via pneumatic actuation or electrical actuation.

[0017] Referring now to FIGS. 2A and 2B, there is shown a perspective view of a jack assembly of an embodiment of the integrated jack system for a vehicle in a retracted position and a perspective view of a jack assembly of an embodiment of the integrated jack system for a vehicle in an extended position, respectively. In the illustrated embodiment, each jack assembly of the plurality of jack assemblies 12 comprises a plurality of telescopic members 15 selectively movable between a retracted position (as shown in FIG. 2A) and an extended position (as shown in FIG. 2B), wherein the extended position the plurality of jack assemblies 12 are configured to frictionally engage a ground surface to elevate a portion of the vehicle frame, such as to elevate a vehicle wheel to replace a tire or perform maintenance on the vehicle. The plurality of telescopic members 15 gradually increase in width from a proximal end 20 of the plurality of telescopic members 15 to a distal end 21 of the plurality of telescopic members 15. In the illustrated embodiments, the plurality of jack assemblies 12 are hingedly affixed to the vehicle frame at the proximal end 20 of the plurality of telescopic members 15, wherein the plurality of jack assemblies 12 are selectively movable between a stored position disposed within a recess of the plurality of recesses 26 parallel to the vehicle frame (as shown in FIG. 1), and a deployed position perpendicular to the vehicle frame (as shown in FIGS. 2A and 2B). In this manner, the plurality of jack assemblies 12 are disposed within the plurality of recesses 26 when not in use to ensure that the plurality of jack assemblies 12 do not interfere with the operation of the vehicle during use. In some embodiments, the plurality of recesses 26 comprise a cross-sectional area slightly less than that of the plurality of jack assemblies 12, such that the plurality of jack assemblies 12 are retained therein via frictional engagement. In such embodiments, when actuated, the plurality of jack assemblies 12 pivot about the proximal end 20 to deploy from the stored position within the plurality of recesses 26. Once the desired jack assembly 12 is in the deployed position, the plurality of telescopic members 15 extend to engage the ground surface to elevate a portion of the vehicle frame.

[0018] In the illustrated embodiment, a foot member 22 is affixed to the distal end 21 of the plurality of telescopic members 15, wherein a lower surface 23 of the foot member 22 frictionally engages the ground surface. In the shown embodiment, the foot member 22 tapers radially outward from an upper end 27 of the foot member 22 towards the lower surface 23, such that the lower surface 23 comprises a larger cross-sectional area than the upper end 27. In this manner, the weight of the vehicle is supported across a larger area to minimize the stress applied to the plurality of jack assemblies 12. In the shown embodiment, a plurality of textured elements 28 are disposed across the lower surface 23, wherein the plurality of textured elements 28 are configured to increase the surface area in contact with the ground surface during use, to frictionally engage the ground surface more securely. In the shown embodiment, the plurality of textured elements 28 comprise a series of parallel linear strips extending across a width of the lower surface 23, however alternate formats of textured elements 28 are contemplated.

[0019] Referring now to FIGS. 3A and 3B, there is shown a perspective view of a dashboard control panel of an embodiment of the integrated jack system for a vehicle and a perspective view of a controller housing of an embodiment of the integrated jack system for a vehicle, respectively. In the illustrated embodiment of FIG. 3A, a control console is disposed within a vehicle cabin, such as integrated into a vehicle dashboard 17, wherein the control console comprises a plurality of controls associated with each of the plurality of jack assemblies. Alternatively, the plurality of controls may be disposed within a controller housing 32 in wireless communication with each of the plurality of jack assemblies, such that the user can remotely actuate each of the plurality of jack assemblies. The plurality of controls includes an extension control 29 and a retraction control 30, wherein the extension control 29 actuates a jack assembly of the plurality of jack assemblies to move the jack assembly to the extended position, whereas the retraction control 30 actuates the jack assembly to move the jack assembly to the retracted position. In the illustrated embodiment, each jack assembly is associated with a separate set of extension and retraction controls 29, 30. In such embodiments, the control console comprises indicia indicating which wheel is adjacent to the associated jack assembly. In some embodiments, a separate control is configured to actuate each jack assembly between the stored and deployed positions, however, it is contemplated that the extension control 29 may deploy the jack assembly from the recess until the jack assembly is perpendicular to the vehicle frame, at which point the jack assembly begins moving to the extended position. Similarly, the retraction control 30 may further store the jack assembly within the recess upon the jack assembly reaching a fully retracted state. Furthermore, in the shown embodiment of FIG. 3B, a power control 34 is disposed on the controller housing 32, wherein the power control 34 is configured to activate the integrated jack system.
