FIELD OF INVENTION
It is believed that 'Necessity is the mother of invention'. Here the necessity lies in reducing the human effort applied during manual operation of the jacks and hence the need of the invention. In day to day life it is very tedious job to operate the jack manually and it is also a very time consuming work as well. So to make it easier for everyone especially for aged person and for lady drivers. To provide a safe and simple automatic hydraulic jacking system without manual effort. To provide a jack system that can be operated from within the vehicle by means of a dashboard control
After considering a number of designs and discarding a few we came up with the design concepts. After a close deliberation of the proposed design we made a comparison with the existing design. Following attributes were compared in convention design and proposed design.
1. Ease & accessibility of items
2. Cost & ease of operation
3. Ease of refitting in present models of vehicles
Each of these attributes is graded according to the data from the market survey, their need & importance in the product design. Accordingly, the adopted concept was marked out with better remarks.

BACKGROUND OF THE INVENTION.
Comparison with present jack for common vehicles
There are various jacks present in the market they are both manual and hydraulic type, the problem with current designs are that we have to carry them separately and human effort is required with them, still they have to be installed with care otherwise accident can take place.
An Inbuilt hydraulic jack In A vehicle can be easily operated by hand operated leaver provided on the dash board. The jack will be installed on both the sides of chassis according to the weight distributions of the car. The system operates on hydraulic drive which consists of three main parts magnetic clutch to drive the hydraulic pump, hydraulic pump and hydraulic cylinder to lift the vehicle. The hydraulic jacks actuate separately for either side of car as per the breakdown condition. This jack will be very useful for all the senior citizens and especially for females (ladies) who find it extremely difficult to operate the jack manually in any breakdown condition. The motive behind using hydraulic system instead of a pneumatic system is the more power produced by the system and simple in design as compared to a pneumatic design. As the hydraulic oil is incompressible so the lifting capacity is more in comparison with the pneumatic system.

SUMMERY
Inbuilt Hydraulic Jack In A Vehicle
An inbuilt hydraulic jack system can be easily attached to all currently manufacture automobile chassis and frames. There is a front suspension hydraulic jack that is mounted both to the front side of an automobile wheels. There is also a rear suspension hydraulic jack that is mounted centrally to the rear suspension of the automobile between its rear wheels.
The system operates on the hydraulic power. This arrangement has many advantages such as maintenance and servicing of vehicle. With the help of this system the driving of vehicles will be easy especially for ladies. Arrangement is also very useful for heavy loading vehicles and a single person can go on a long drive. Whole system is operated by hand operated lever which is located on dash board, when vehicle will not in starting condition. Jacks can work individually.
This jack will be very useful for all the senior citizens and especially for females (ladies) who find it extremely difficult to operate the jack manually in any breakdown condition. The motive behind using hydraulic system instead of a pneumatic system is the more power produced by the system and simple in design as compared to a pneumatic design. As the hydraulic oil is incompressible so the lifting capacity is more in comparison with the pneumatic system.

DESCRIPTION OF THE PRFERED EMBODIMENT
In figure-01,
100-1. Reservoir: this is the hydraulic oil pool which is already present in the vehicle.
100-2. Hydraulic pump. It is used to supply hydraulic oil under pressure in the hydraulic cylinder.
100-3. Filter. The filter is used to clean the foreign impurities from the oil, it is already present in the car.
100-4. Pressure switch. Automatically senses a change in pressure and opens or closes an electrical switching element, when a predetermined pressure point is reached.
100-5. selector valve: A selector valve is used to control the direction of movement of a hydraulic actuating cylinder, this valve is manually actuated only when we want to use jack in the vehicle.
100-6. Actuator: It uses hydraulic power to facilitate mechanical operation, it lift the vehicle.
100-7 Relief valve: pressure-control devices that are used to dump excess fluid to tank at little or no pressure. It is used as safety device in our innovation.

What is claimed as:
1. We claim that this proposed design of Inbuilt Hydraulic Jack In A Vehicle, the maintenance, servicing, washing will be easy and cheap.
2. We claim that the proposed design of claim 1 can be used in small cars as well as in heavy loading vehicle like trucks and buses.
3. We claim that the proposed design of claim 1 is Useful in case of puncher of tires, change of wheels and other small repairs.
4. We claim that the proposed design of claim 1, when the car get stuck in mud or dug the particular jack can operated and placing flat stone or like things the vehicle can be easily removed.
5. We claim that the proposed design of claim 1 is also useful for heavy vehicles such as trucks and buses, since there is a common problem of breaking leaf spring plates, this system will help in changing of leaf spring plates.
6. We claim that this proposed design of Inbuilt Hydraulic Jack In A Vehicle is very useful for all the senior citizens and especially for females (ladies) who find it extremely difficult to operate the jack manually in any breakdown condition.
7. We claim that the proposed design of claim 1 is safe and simple automatic hydraulic jacking system without manual effort.
8. We claim that the proposed design of claim lean be directly and permanently incorporated into the vehicle frame in such a way as to prevent the additional risk of damage or weathering.
