| claims The car lifting & parallel parking Aid: 1- consist of : (a) half of scissor lift operate by electrical (b) side fender works as base of the half scissor lift (c) side fender roll around it self by electrical motor (d) control keys 2- According to the above mentioned item ( No. 1 - a) half of scissor lift operates by electrical motor hidden under the car to lift the car up & lower down for car repairs , tier change , get out of sand traps 3- According to the above mentioned item (No. 1 - a) the half of the scissor lift screwing bar is screwed from left to wright from beginning to the middle and screwed from wright to left the other half, and each half is having a speciahnut, thus by rolling the screwing bar around itself, both nuts will move against each other to meet in the middle, and by rolling the screwing bar around itself again, both of the nuts will move vice-versa. (This will cause fast lifting up and lowering down operation). 4- According to the item No. (1- b) the side fender which is located in car side works as lift base for the No 2 operation. 5- According to the item No. (1 -c) the car side fender is able to roll- around itself by electrical motor to accomplish car moving aside for parallel parking purposes. 6- According to the item No. (1-d), of control keys for controlling lift up & down & moving car left & right (after lifting). 7- According to the item Nb.(1 -d), the control box is having a cover which switch on power when open & power off when close, for the control box to avoid accidental functioning of control keys due to electrical short circuits. 8- According to the item No. (1- d) the control box should be located under the hand-break, (in other words, the control box will not be reachable unless the car is stopped) to avoid human errors. |
Technical field :
It is a part of the car accessories industry.
Background art :
• Car lifting is done by using manual lift or electrical lift.
• parking system depends on using a high sophisticated technology mixing computer programs with cameras plus electro-hydraulic system controlling driving wheels in order to have a parallel parking for the car.
This system must build in the car during manufacturing operation and it made for expensive cars, and needs to train the driver how to use it.
The driver should be well educated and having good idea about how to handle the computer.
The dis-advantages of the old car lifting and car parking system :
a) For lifting, driver should carry the jack out of car trunk & fix-it under the car. And then lift it manually or by electricity which takes 90 seconds for lifting
B) For parallel parking, Using a parking area not less than 1.5 time of the actual car length (such space is hard to find inside cities).
- Expensive cost of the parallel parking system due to the high-tech used
- Possibilities of system breakdown is high due to a variety of sets involved in parking operation
(I.e. camera, computer, software, electro-hydraulic system)
- Driver should be familiar with computers and high-tech
- The system must build in the car during manufacturing.
- High cost of repairs and maintains plus needing of highly trained technicians to carry such repairs The new car lifting & parking aid system
- The set of car lifting & parking Aid, lift car with in 10 second by pushing a bottom
- The set of car lifting & parking Aid, will take less than 15 seconds, and Could park a car in an area equal to the length of the car (plus 40 CMS. for safety reasons).
- The set of car lifting & parking Aid, Could be fixed in most cars (old or new) within one hour.
- The set of car lifting & parking Aid, is a very easy parking system could be used by uneducated and old drivers.
- The set of car lifting & parking Aid, Supply the car with a side fenders
- The set of car lifting & parking Aid, Supply the car with a build in electrical lift (safe and fast) for proceeding with tiers repairs or maintains, getting out of sand traps.
- The set of car lifting & parking Aid, Cheap cost (less than 1000 USD)
- The set of car lifting & parking Aid, Using very simple technology, meaning fewer breakdowns, easy repairs (could be handle by most technicians.
Disclosure of invention :
It is a metal shape to be fixed in the bottom of the car and ended with two sides' car fenders.
This above metal set is equipped with hidden electrical motors controlled by a control box located inside the car.
The set is working according to the below sequence:
- Through the control box the sides' fenders will be lowered against the road surface
causing lifting the car up.
- Through the control box, both of the side fenders will roll around them self in the same direction (left direction or right direction) causing car moving by side to have a parallel parking).
- By having the car lifted up, it will be easy to change tiers or executing car maintains.
- The electrical lifting system could be used to get the car out sand traps. Brief Description of Drawings

Fig. 1 description
A metal shape of four sides, three of them are pipes and the fourth is a screwed metal bar (half of it screwed from left to Wright and the other half is screwed from Wright to left)
And a nut having connecting point is attached to each half of the above mentioned screwed bar.
The screwed bar is ended with tow electrical motors to roll it around itself.

Two metal pipes ended with connecting points from both sides
Fig 3
A metal shape of four sides, three of them is pipes and the fourth side is the car sjde fender
The side car fender is ended with tow electrical motors to control it move around itself.
By assembling the parking aid by connecting the below mentioned points
F1 to C5
C5 to C3
F2 to C7
c8 to c4 By having two identical copies of the above mentioned structure fixed in both of the car side
A control box with a cover and four buttons
- The cover is working as a main power switch, when it is open the power is on and by closing the switch cover, the power is off.
- First, for lifting up.
- Second, for lowering down.
- Third, for moving the car to the left side.
- Forth, for moving the car to the Wright side.
