US Classification:

431153

Abstract:

A safety lighter having a safety thumb-wheel design that will prevent accidental ignition and unauthorized use by children. The safety lighter can be ignited with one easy press of the thumb-wheel without any additional manipulation of slides or switches. The safety thumb-wheel design consists of a friction thumb-wheel assembled between two side thumb-wheels on an axle. The two side thumb-wheels has a circular shallow indentation on the face that contacts the friction thumb-wheel. The inside diameter of the circular shallow indentation is slightly larger than the outside diameter of the friction thumb-wheel such that the friction thumb-wheel can be inserted in the circular shallow indentation. When pressing down with moderate force on the two side thumb-wheels, they will engage the friction thumb-wheel, which in turn bears against a flint to create a spark.
