Abstract: A combustible fluid lighter includes a body with a reservoir for combustible fluid and a striking mechanism. A movable control member has at least two degrees of freedom and is manually actuated. The assembly of the control member and striking mechanism is a kinematic train which includes a coupling having two parts that are uncoupled in a rest position. At least one of these parts is displaceable for engagement by a movement of the control member other than that necessary for actuating the striking device. A resilient member is provided to return the coupling to its uncoupled position. The actuating member is a rotatable wheel adapted to drive in rotation a portion of the striking mechanism. The coupling can be a clutch device, in which case a relative axial displacement between the rotatable wheel and a portion of the striking device is necessary for engaging the two parts of the coupling.

Abstract: The ignition device of the lighter comprises a striker wheel (6) acting on a spark stone (2). The striker wheel is disposed between two plates (7) and (8) of greater diameter than and freely rotatable with respect to the wheel. Actuation of this latter is obtained by friction thanks to the deformation (11) of the pulp of the thumb (10) of the user, and may not be driven by a child as the pulp of the finger of children is not sufficiently thick.
