Description:
BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to vehicular leveling systems and more particularly pertains to a new vehicle jacking system for jacking up a quadrant of a vehicle to facilitate a maintenance action. 
   2. Description of the Prior Art 
   The use of vehicular leveling systems is known in the prior art. U.S. Pat. No. 3,860,216 describes a system using a ram and a pivotal lift system. Another type of vehicular leveling systems is U.S. Pat. No. 5,188,379 having four jack assemblies for leveling a vehicle. 
   While these devices fulfill their respective, particular objectives and requirements, the need remains for a system that has certain improved features such as manual actuation and quadrant selectable lift. 
   SUMMARY OF THE INVENTION 
   The present invention meets the needs presented above by providing fixed jacks permanently affixed to the chassis of an automobile. 
   Still yet another object of the present invention is to provide a new vehicle jacking system that allows a car to be jacked up to facilitate replacing a tire. 
   Even still another object of the present invention is to provide a new vehicle jacking system that increases user safety by eliminating separate jacks which can slip out of position. 
   To this end, the present invention generally comprises an automobile having a chassis and a body; and at least one jacking assembly operationally coupled to the chassis for facilitating elevation a quadrant of the automobile. 
   There has thus been outlined, rather broadly, the more important features of the invention 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 invention that will be described hereinafter and which will form the subject matter of the claims appended hereto. 
   The objects of the invention, along with the various features of novelty which characterize the invention, are pointed out with particularity in the claims annexed to and forming a part of this disclosure. 

   
     BRIEF DESCRIPTION OF THE DRAWINGS 
     The invention 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: 
       FIG. 1  is a schematic perspective view of a new vehicle jacking system in use according to the present invention. 
       FIG. 2  is a schematic bottom view of the present invention. 
       FIG. 3  is a schematic front view of the control assembly present invention. 
       FIG. 4  is a schematic perspective view of an embodiment of the present invention. 
   

   DESCRIPTION OF THE PREFERRED EMBODIMENT 
   With reference now to the drawings, and in particular to  FIGS. 1 through 4  thereof, a new vehicle jacking system embodying the principles and concepts of the present invention and generally designated by the reference numeral  10  will be described. 
   As best illustrated in  FIGS. 1 through 4 , the vehicle jacking system  10  generally comprises a quartet of jacking assemblies  20 , a hydraulic pump  30  and a control assembly  40 . The system  10  may be retrofit onto an automobile  50  or be part of the automobiles  50  original equipment. Each one of the jacking assemblies  20  is coupled to the chassis  52  adjacent to an associated corner of the chassis  52 . Each one of the jacking assemblies  20  is hydraulically actuated. The hydraulic pump  30  is operationally coupled to the chassis  52 . The hydraulic pump  30  is fluidly coupled to each one of the quartet of jacking assemblies  20  for facilitating actuation of each one of the quartet of jacking assemblies  20 . The control assembly  40  is operationally coupled to the hydraulic pump  30 . The control assembly  40  is used for selecting which one of the quartet of jacking assemblies  20  is to be actuated by the hydraulic pump  30 . 
   In an embodiment the control assembly  40  includes a housing  42  couplable to a dashboard  56  of the automobile  50 . The control assembly  40  includes a power switch  44  for controlling the hydraulic pump  30 . The control assembly  40  includes a plurality of actuators  46  for selecting which one of the quartet of jacking assemblies  20  is actuated by the hydraulic pump  30 . The control assembly  40  includes a power on indicator  48  for providing a visual indication to a user that power is applied to the hydraulic pump  30 . 
   In another embodiment the automobile body  50  includes an opening  60  and a cover member  62  hingedly coupled to the body  54 . The cover member  62  is for selectively covering the opening  60 . At least one jacking assembly  20  is operationally coupled to the chassis  52  adjacent to the opening  60 . The jacking assembly  20  facilitates elevation a quadrant of the automobile  50 . The jacking assembly  20  includes a manual actuation means  22 . A hand crank  24  includes a first end  25  and a second end  26 . The first end  25  is selectively couplable to the manual actuation means  22 . The second end  26  is designed for is grasped by a human hand. The hand crank  24  is rotatable. Rotating the hand crank  24  actuates the jacking assembly  20  and a quadrant of the automobile  50  is elevated. 
   In use, the user determines which quadrant of the automobile need to be elevated and selects the proper control actuator of the control assembly. The control assembly activates the hydraulic pump and actuates the appropriate jacking assembly. The user then performs any maintenance tasks requires, such as changing a tire. The user then activates the hydraulic pump again via the control assembly to return the jacking assembly to a stored position. 
   With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, 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 the present invention. 
   Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention 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 invention.
