ELECTRODYNAMIC LANTERN Russian patent published in 1996 - IPC

FIELD: domestic lighting equipment. SUBSTANCE: lantern has case 25 inside which electric generator is disposed. The generator has pack of plates 1 made of electrical-sheet steel, electric windings 2 reeled upon packs 1, electric lamp 3, lamp-holder 4, electric wires 5 which connect windings 2 with lamp-holder 4. Generator also has rotor which has flywheel 6, axis 36 and magnet 8 built into the rotor. Generator is provided with reflector 30, gear 16, rest 29, handle 9 of spring- loaded device provided with teeth. Handle 9 is made in form of a strap. There are protrusions 10 and 11 at opposite sides of the strap. There is a hole in one protrusion for hinge connection with axis 13 onto which spring 14 is mounted. Teeth-shaped segment 12 is mounted at opposite protrusion. Segment 12 is connected with gear wheel 15 which is brought into contact with larger diameter gear 16. Gear 16 is connected with smaller diameter gear wheel 17. Wheel 17 is brought into coincidence with flange 18, onto peripheral part of which catches 22 are mounted. The catches are mounted in holes of flywheel 6 onto one its surface. Magnet 8 and tooth-shaped segment are mounted at the other surface of flywheel; segment 12 is made of shock-proof material. Flange 18 of gear 17 has wedge-shaped grooves 19. The grooves end with holes 20 for axes 21 and catches 22. Diameters of catches are larger than width of base of wedge- shaped grooves, but smaller than diameter of hole 20, flange 18 and gear 17. Distance between jaws of catches 22 is larger than thickness of flange 18 of gear 17. Catches have symmetrical shapes. EFFECT: improved efficiency of operation. 3 cl, 5 dwg
