Abstract:
1. A piezo ignition device which includes a piezo electric crystal that is intended to generate a spark on an electrode of said device in response to force exerted on the crystal, wherein the ignition device is mounted parallel with and is firmly clamped to a mixer pipe by a clamping ring which delivers fuel to an open-air cooking apparatus, and wherein the piezo electric crystal is positioned so that the force applied to the crystal is directed parallel with the mixer pipe, wherein the force acting on the piezo ignition device for ignition purposes is adapted to be applied parallel with and to one side of the piezo ignition device in a direction from the electrode by a lever which functions to produce the force acting on said piezo electric crystal and the lever includes a short lever end and a long lever end, and wherein the lever is mounted on a pivot pin which is oriented at right angles to said mixer pipe, so that said short lever end is adapted to displace the plunger, said long lever end having an angled portion and a longer straight portion, the clamping ring having a length proximate to the longer straight portion of the long lever end, such that when a pulling force is exerted on said angled portion of the long lever end, the open-air cooking device remains stable.
