Abstract:
A lighter of improved safety, comprising:an idle wheel (21) having course grains along the circumference thereof;two ratchet arms (23,23') disposed on a top surface of the lighter each having an egg shaped slot (231,231') therein, each said egg shaped slot having an upper portion and a lower portion;an axle (211) on which said idle wheel is mounted, said axle having an oval shape with a minor axis and a major axis, said axle being mounted in the egg shaped slots (231,231') of said two ratchet arms (23,23');a seat (24) positioned below said idle wheel;a tension spring (241) received within said seat (24);a flint bar (243) being connected to a grooved base (242) received within said seat (24) so that said tension spring (241) acting on said grooved base (242) urges said flint bar (243) against said idle wheel (21),the upper portion of said egg shaped slots (231,231') being slightly larger than the minor axis of said axle (211) and the lower portion of said egg shaped slots (231,231') being slightly larger than the major axis of said axle (211),so that said axle (211) is disposed in the upper portion of said egg shaped slots (231,231') by the urging of said flint bar (243) against said idle wheel (21) whereby rotation of said axle (211) within said egg shaped slots is prevented and upon application of a force on said idle wheel (21) counter to the bias of said tension spring (241) said axle (211) is disposed in the lower portion of said egg shaped slots (231,231') so that the axle may be rotated to rub against said flint bar (243) to ignite a gas emitted by a gas nozzle (25).
