FIELD OF INVENTION:
The present invention relates to portable laptop stand. More particularly the
present invention relates to the foldable flap attached to the bottom of the laptop
stand that raises the laptop high enough to allow adequate ventilation for heat
dissipation from under the laptop.
DESCRIPTION OF THE RELATED ART:
Since the introduction of the laptop computer, users have had the convenience of
having a portable computer that can be carried around, opened and used where
ever they want. This however requires the user to rest hislher laptop computer
either on a desk or table surface, or on the lap. This creates in the user an angle of
view that is downward and causes neck and shoulder strain over a period of time.
Also the physical dimensions of laptop computer prevent the heat generated from
the electronic components from dissipating well enough. The heat buildup has
become an issue that effects the lifespan of the internal components and in some
cases has even become a safety issue due to fire hazard. The most noticeable
drawback of this heat buildup inside a laptop computer's CPU is the heat exposure
suffered by the user when it is used on his or her lap, which does, in most models,
become far too excessive to enable extended use. This is a worldwide problem
associated with laptops. The excessive use results in heating up of laptops which
eventually leads to many problems like battery damage or shutdowns.

The "Laptop Flip 2-in-1 Stand" talks about the laptop Flip which is a 2 in 1 stand
that helps keep your laptop tidy when not in use and keep it cool while in use.
Raising your laptop increases ventilation and reduces heat. The Laptop Flip raises
the back of your laptop and also lets you store your laptop in the vertical position
when not in use creating additional space on your desktop.( Matthew,2009)

your MacBook Pro made of a single solid piece of aluminum that matches Apple's
sandblasted and silver-anodized finish. mStand raises the screen to meet eyelevel
for better posture and view, raising the screen to the same height as external
displays, like the Apple Cinema Display. The tilt design brings the screen closer
and improves airflow around the laptop. The single-piece aluminum design
provides solid stability and the aluminum panel cools laptop by serving as a heat
sink. ( Sears Brands, LLC.20 12)
Thus in the view of above prior art, there are several laptops stands available in
the prior art, all have number of disadvantages inherent in their design that make
them too elaborate or too complicated ,not high for computer ergonomics, not
-4-
Portable, expensive and not ventilating properly to remove the dissipating heat
from the laptop.
Therefore the present invention overcomes the aforementioned disadvantages by
providing a user friendly laptop stand that allows a user to work comfortably.
OBJECTS OF THE INVENTION:
The principal object ofthe present invention is to provide a portable lightweight
foldable laptop stand that allows certain alleviation in laptop computer.
Another object ofthe present invention is to provide foldable laptop stand that
uses a flap to alleviate the laptop to a certain height.
Yet another object of the present invention is to provide a foldable laptop stand
that dissipates heat from the base of the laptop.
Still another object of the present invention is to provide a foldable laptop stand
that securely stores your laptop in vertical position freeing up desk space.
Another object of the present invention is to provide a foldable laptop stand that
creates better ventilation.
Still another object of the present invention is to provide an inexpensive foldable
laptop stand that is easy to assemble at the base.
SUMMARY OF THE INVENTION:
The present invention relates to a laptop stand, and, more particularly, relates to
foldable laptop stand that can be coupled to a bottom surface of the laptop
computer .The present invention provides a foldable flap at the base of the laptop.
When the laptop is in use, this flap can be opened .and it will raise the base of
laptop from the surface to a certain height. This will increase the clearance of
laptop from the surface on which it is kept and thus will help in reducing the
heating. The foldable laptop stand is very inexpensive, extremely lightweight and
easy to assemble and disassemble and can fold flat for portability.
In a preferred embodiment of the present invention a foldable laptop stand is
provided comprising foldable flaps attached to the bottom of the laptop which are
attached at the base of the laptop via half hinge joints and flaps having spring
fixer to fix one end of the spring on the flap, with stopper to hold the flap onto the
ridge.

In another embodiment of the present invention, the first portion and the
second portion of the laptop support surface are coupled to each other in a fixed
positional relationship.
In still another embodiment of the present invention flaps simply open by
placing fingers below the elevation (E) and dragging it till the stoppers(s) fit into
the ridges (Rl).
In yet another embodiment of the present invention, when the stopper(S) fits
into the ridge (Rl) the spring becomes tensed (Spt). This tensed spring keeps the
stopper(S) in place. These flaps will make a triangular arrangement, which will
elevate base of the laptop by 2.23 centimetres.
In still another embodiment of the present invention, the height of the base is
increased a little more placing the stoppers to Ridge 2. This will increase the
height to 2.59 centimeters.
It is to be noted, however, that the appended drawings illustrate only typical
embodiments of this invention and are therefore not to be considered for
limiting of its scope, for the invention may admit to other equally effective
embodiments.

DESCRIPTION OF THE PREFERRED EMBODIMENTS:
Accordingly, the present invention relates to lightweight, inexpensive foldable
laptop stand that uses the flap attached to the bottom of the laptop that raises the
laptop high enough to allow adequate ventilation for heat dissipation from under
the laptop. The present invention relates generally to laptop stands, and, more
particularly, it relates to foldable laptop stand that can be coupled to a bottom
surface of the laptop. The present invention provides a foldable flap at the base of
the laptop. When this laptop is in use, this flap can be opened and this will raise
the base of laptop from the surface to a certain height.

Referring now to FIG. 1, one embodiment of the present invention is shown in a
perspective bottom view. The laptop contains 4 hinges (F1 and F4) as seen in
figure 1 which are attached at the base of the laptop via Half Hinge Joints (a).
Hinges F2 and F3 are attached to F1 and F4 respectively via Full Hinge Joints (b).
Flaps 2 and Flaps 4 have El (Spring Fixer 1 to fix one end of the spring on the
flap), E (Elevation to facilitate the opening and closing of the flaps), S (Stopper to
hold the flap onto the ridge). The base of the laptop is provided with E2 (Spring
Fixer 2), T (Hollow tunnel through which the spring passes), RI and R2 (Ridge 1
and Ridge 2 which are 4 cm and 2 cm from the Hinge Joint (a) respectively.
These Ridges are hollow slits which will hold stoppers (S). GI and G2 (Groove 1
and Groove 2 and 4 cm and 2 cm from the Hinge Joint (a) respectively. These
Grooves remain just below the Elevation (E) and provide a depression for our
fingers to hold the flaps.
In normal condition (flap closed condition) as shown in fig 3, the spring remains
in a relaxed condition (Spr) and the flaps of the laptop has to keep parallel to the
base of the laptop.
To open the flaps we simply place our fingers below the elevation (E) and drag it
until the stoppers(s) fit into the ridges (Rl). As soon as the stopper(S) fits into the
ridge (Rl) the spring becomes tensed (Spt) as shown in fig 2. This tensed spring
-7-
will keep the stopper(S) in place. These flaps will make a triangular arrangement,
which will elevate base of laptop by 2.23 centimeters.
In order to increase the height of the base little more to place the stoppers to
Ridge 2 This will increase the height to 2.59 centimeters as shown in fig 4.
To close the flaps again place the fingers below the elevation (E). There the
grooves (GI) will facilitate this process. The flap is dragged gently unless the
stopper(s) comes out of the ridges (Rl). Once it is out, the flaps are released and
the spring will again be parallel to the base of the laptop.
Numerous modifications and adaptations of the system of the present
invention will be apparent to those skilled in the art, and thus it is intended
by the appended claims to cover all such modifications and adaptations
which fall within the true spirit and scope of this invention.
