Abstract
A utility lighter ( ) with an ignition-resistant mechanism. The ignition-resistant function is performed by a cam mechanism ( ) having a hub ( ). The hub has three integral projections: the cam lever ( ), the fuel-release lever ( ), and the return spring ( ). Integral to the cam lever is the safety button ( ) which when depressed disengages the cam lever ( ) from the stopper tab ( ) of the trigger ( ). The trigger ( ) also has an inclined surface ( ) below the stopper tab ( ) which the cam lever ( ) engages after the safety button ( ) is depressed and the trigger ( ) is pulled. Once the trigger ( ) is pulled, the cam lever ( ) moves along the inclined surface ( ) rotating the cam mechanism ( ). When the cam mechanism ( ) is rotated the fuel-release lever ( ) opens the fuel-release valve ( ) allowing fuel to transfer through to the lighting rod ( ). When the safety button is released the return spring ( ) urges the cam mechanism ( ) to rotate back to the initial locked position.
