Patent ID: 6991221

Claim:
An automatic jacking system for mounting to a frame underside of an automotive vehicle adjacent the wheels of the automotive vehicle, comprising: a plurality of jacks with each jack hingably mounted to the frame underside adjacent each wheel of the automotive vehicle and movable between a folded storage position and a use position for selectively raising that portion of the automotive vehicle adjacent each respective wheel; each jack including: a main cylinder having a slidable piston disposed therein; a locking solenoid mounted to each jack for locking the jack in place after the jack has been disposed to the use position for raising the automotive vehicle adjacent that respective wheel; a plurality of secondary solenoids with each secondary solenoid mounted to the frame underside adjacent each jack to assist in controlling the extension of each jack to the use position and the retraction of each jack to the folded, storage position; a hydraulic system for supplying hydraulic fluid to the main cylinders of the jacks after each respective jack has been disposed to the use position so that the jacks can actuate the raising and lowering of the automotive vehicle; the hydraulic system including a fluid reservoir in communication with an electric pump and hydraulic lines extending from the pump and reservoir to each jack; a plurality of leak detection sensors with each leak detection sensor coupled to each jack for detecting the occurrence of a hydraulic fluid leak associated with that respective jack and in the hydraulic system; a control panel electrically interconnected to the jacks, the locking solenoids, the secondary solenoids, the electric pump and the leak detection sensors and having an electrical cord of a length to allow an individual to move about the automotive vehicle to monitor the operation of the jacks during the raising and lowering of the automotive vehicle; and the control panel including four control switches with each control switch coupled to each jack for controlling the disposition of the jacks from the folded position to the use position, an up/down switch for initiating the extension and retraction of the piston for raising and lowering the automotive vehicle, and a locking switch for actuation of the locking solenoid to lock the jack in place after the extension of the piston to raise the automotive vehicle.
