ABSTRACT : A door activated chargeable power / light
source comprises of a lamp or light
emitting diode and a powering system. The power system consists of gear set
mechanism, a mini power generator, and an accumulator. The gear set mechanism
has an extended lever which moves in and out thereby driving the mini generator
to help charge up the accumulator or a rechargeable battery. This device is
mounted on door frames while the extended lever is secured to the door. When
the door opens and closes, energy is
provided to charge the battery and keep the light source glowing.
BACK GROUND OF THE
INVENTION:
001 – Field of
Invention. The present Invention relates
to use of movement of doors to charge power / light source.
002 - Description of Prior Act. A light source is a necessity in every house
hold, office, public place, and industrial establishment. This invention seeks
to supply the light/power source with a rechargeable battery which in turn is
energized by the opening and closing of the doors in that area/building. It seeks
to eliminate the use of electrical power for simple and minor utilities.
003 - SUMMARY OF
INVENTION
The prime
objective of the present invention is to supply a cheap and freely available source
of alternative power supply. This invention can be installed on all main doors
of houses or business units located in remote areas and under developed
countries, specially where electrical power is not available.
004 – Accordingly
the present invention provides a set of two steel plates bolted at four corners
to house all the components.
005 - Accordingly a set of five accelerating gears
is provided to energize the accumulator. The first gear has an extended lever
and the last gear is coupled to the mini generator.
006 – Accordingly
these two gears, the first and last are also one way clutches to facilitate the
rotation in only one desired direction.
007 – Accordingly
a fly wheel is mounted on the last gear to store up the energy and facilitate
smooth running of the mini generator.
008 – Accordingly
a circuit board is provided to convert the alternating current generated into
direct current to enable the charging of rechargeable battery and prevent the
overcharging too.

DETAILED
DESCRIPTION OF THE PREFERRED EMBODIMENT
013 - Referring to
fig 1, we see how the present invention will be mounted on door frames with the
help of four screws. The necessary legs 16 have been provided for the purpose
of mounting. The extended lever 1 will also be firmly secured to the door with
four screws. The face plate for this purpose is an integral part of the
extended lever.
014 – Referring to
fig 2, we see the detailed mechanism of the one way clutch gears 2 and 10. The
three ball bearings will allow the gear to rotate in counter clockwise
direction freely. The same ball bearings will lock in when they are required to
rotate in the clockwise direction, because of the tapered cavity.
015 – Referring to
fig 3, we see the plan view of the total mechanism sand- witched between two
steel plates 15. The extended lever 1 moves with the motion of the door. When
the door is opened the lever moves inwards into the device. It is a rack gear designed
in the shape of a half circle. This rack gear engages the first pinion gear 2
and rotates it, thereby rotating the next gear 3, which is axially on the same
shaft. Big gear 3 meshes with smaller gear 4 and accelerates the process of
rotation, by a factor of four. Gear 5 which is axially on the same shaft as
gear 4 rotates faster by engaging another small gear 6 accelerating it further
by a factor of sixteen. Big gear 7 is mounted axially on the same shaft as gear
6. Another small gear 8 engages gear 7
and carries the gear train forward to the next level, a factor of sixty-four. Next
big gear 9 is axially mounted on the same shaft as gear 8. Finally the last
small gear 10 meshes with big gear 9, rotating the fly wheel 11 and mini generator
12 at a factor of two hundred fifty-six. Gear 2 is also one way clutch,
allowing the extended lever 1 to return back freely when the door closes,
pushing it outwards. Gear 10 is also one way clutch allowing the flywheel and
the mini generator to keep on rotating freely, even when the rest of the gear
train is stationary. One rotation of the small gear 2 will rotate the last gear 10, nearly two hundred and
fifty-six times.
