DESCRIPTION
The present invention relates to Vertical sliding doors and more particularly to Vertical sliding doors for automobiles which open at a ninety degree angle upwards without taking much space.
BACKGROUND OF THE INVENTION
In general, the automobiles door i.e. an opening to enter to the car (or their compartments or partition), is often equipped with a hinged or sliding panel which can be moved to leave the opening accessible, or to close it more or less securely.
At present there are several types of doors in automobiles, which are: -Scissor, aka lam bo, vertical
The most well known of the different doors. The name scissor comes from the way it comes straight down like a pair of hand scissors. Because Lamborghini TM knew that their door would be opening this way, they have the A-pillar out of the way, and the door comes straight down, just like the blade on your scissors. The pivot point is usually at the top comer of the door, near the A-pillar. It is assisted by a shock to raise the weight of the door.
Gullwing type door:-
The Gullwing name comes from the profile of the doors open when looking straight at the car. They rise up as if a seagull in mid flight, about to swing its wings down. The pivot point for these doors is above the passenger compartment, where the roof is. This means the roof needs to be nicely supported because the weight of the door will be placed squarely on the top. SUV's use this setup for their hatchbacks. The door pivots on the roof, opens straight up, out of the way.

Butterfly
Butterfly wings are close to scissor doors in that there pivot points are very close, and the doors end up in the same area. The difference is that with butterfly the pivot is usually on the a-pillar so that the doors turn towards the front, exposing more of the side of the door towards the front. The profile of a scissor door would be much less from a front angle... a butterfly lets you see the side of the door as it pivots sideways and turns up.
Suicide
Suicide doors have their pivot on the exact opposite side of "regular/OEM" doors, so they open up "backwards". The most common place you will see this is on newer trucks with extended cabs. Truck companies realized that they could have a bigger opening if they put the hinge on the other side, and now bigger people can squeeze into those little compartments behind the front seats. These doors are called suicide because if the car was driving, and you decided to roll out, you be killed by the door smacking into you, whereas a "regular1 opening door wouldn't be there to ruin your day with a headshot.
Dihedral Synchro-Helix Door Actuation
These have a geared rotational pivot operates simultaneously with a parallel arm, in an outward arc. Balanced by gas struts the doors lift easily to allow entry, their refined "flying punch" movement setting the stage. The doors require minimal area around them and above the vehicle, giving complete freedom of access to the car in confined areas. They come out as they rotate up easily. These are not scissor doors in the strict sense... although they do have: a similar in motion.
Horizontal Sliding Doors:
The present horizontal sliding doors take up a lot of space to open up because the door is first pushed open to about some 6-8 inches and then it slides in the Horizontal Direction.

SUMMARY OF INVENTION
To solve the above-described problems, it is an objective of the present invention to make the present invention more advantageous and technically sound than the conventional methods. The present invention relates to Vertical sliding doors and more particularly to Vertical sliding doors for automobiles which opens at a ninety degree angle upwards without taking much space.
In accordance with one aspect of the present invention the automobile door is made up any material most preferably fiber or any other light weight material and even steel could be used. In the present invention the doors slide vertically upwards by any means such as manual or automatic. The present door system uses a railing wherein the wheels for sliding the doors are inside the railing rather than outside as in the conventional horizontal sliding system, thus taking lesser space for opening the door.
The present invention in comparison with the prior art, is simpler, lighter, takes up less space, and is more forgiving in terms of door and frame distortion and misalignment.
Vertically sliding door technology also lends itself to the design of special vehicles for physically handicapped drivers. Because door operation is automatic, there is no problem in opening or closing the door for a person on crutches or in a wheelchair. The door does not swing out and limits the access of the door opening to a wheelchair, as do conventional doors.
