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 on 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.
016 – Referring to fig 4, we see the elevation view of the present invention.
We can see the predetermined path of the extended lever 1, which is achieved with set of multiple roller bearings. The circuit board 13 is conveniently located in top corner adjacent to the mini generator 12. The output socket for the power / light source is also located here, right next to the accumulator 14.
017 – It is of course to be understood that the embodiment discussed here in is merely illustrating the principle of the invention and that a wide variety of modification thereto may be effected by person skilled in the art of design and manufacture, without departing from the spirit of the invention as set forth in the above mentioned claims of the present invention.
018 – It is to be understood that different materials can be used for light duty and heavy duty applications. Depending upon the environmental conditions, the whole invention will be encased in a plastic molding to prevent it from malfunctioning and enhancing its life.
