Abstract:
A safety lighter, comprising: a. a supporting frame disposed on top of a gas reservoir housing having a valve which is actuated by a gas lever pivotally mounted on the supporting frame for actuating the valve to release gas within the gas reservoir housing, the supporting frame having two upright supporting walls parallel protruding on opposite sides of the gas lever and each supporting wall having a supporting hole thereon; b. flint means extending upwardly from said supporting frame and between said two upright supporting walls; c. a strike wheel having a first axle hole end, a second axle hole end, an internal bore extending between the axle hole ends and an external striking surface in contact with said flint means, wherein said flint means is retained urging against the striking surface for generating sparks directed toward said valve when the striking surface is driven to strike against said flint means; d. a pair of side turning wheels each having a wheel portion with a bevel rim, a protruding axle portion centrally located on one side of the wheel portion for rotatably inserting into said respective supporting hole, and a protruding frusto-conical attachment portion centrally located on the other side of the wheel portion and tapered therefrom, the protruding frusto-conical attachment portion having an external toothed surface respectively inserted into said axle hole ends of said strike wheel such that the external toothed surface of said protruding frusto-conical attachment portion of said each side turning wheel engages with said internal bore of said strike wheel to secure the pair of side turning wheels to said striking wheel; and e. a pair of driving rings each having an external knurling surface and an internal bevel rim surrounding a central driving hole, the central driving hole having a diameter slightly larger than said wheel portion of said each side turning wheel, where the internal bevel rim is respectively and loosely mounted on and corresponds to said bevel rim of said each side turning wheel, so to engage said bevel rim of said each side turning wheel to loosely rotate around said each side turning wheel without being depressed, thereby when a depressing force is applied downwardly to the pair of driving rings which in turn depress and turn said pair of side turning wheels, so that said frusto-conical attachment portion is respectively pressed to engage with said strike wheel to drive and strike against said flint means; f. whereby to operate said safety lighter, a user must press on said pair of driving rings to have them frictional engage with said pair of axle wheels respectively to turn said strike wheel so that said striking surface strikes said flint means to create a spark.
