A child safety lighter (10) including a pair of pivot elements, one (40) of which engages a valve stem (30) for moving a valve (28) between closed and open positions upon pivoting the element by application of thumb pressure to a first finger-engageable surface (44). The second element (50) includes a second finger-engageable surface (52) extending about the outer periphery of the first surface (44) whereby the two surfaces (44, 52) combined correspond in shape essentially to a typical thumb press pad of a conventional lighter. The second element (50) is independently pivoted against the bias of a spring (56). Because the first surface area (44) is reduced and located between the second surface (52) and the spark wheel (20) of the lighter, increased force and dexterity is necessary to pivot the first lever to actuate the lighter (10).
L'invention concerne un briquet (10) de s~curit~ enfant comprenant deux ~l~ments d'articulation, l'un (40), en prise avec une tige de soupape (30), d~place la soupape (28) entre une position ferm~e et une position ouverte par pivotement par application d'une pression du pouce ~ une premire surface (44) de contact tactile. Le second ~l~ment (50) comporte une seconde surface (52) de contact tactile entourant la p~riph~rie de la premire surface (44), la combinaison des deux surfaces (44, 52) correspondant sensiblement ~ la forme d'un coussinet de pression de pouce ordinaire d'un briquet classique. Le second ~l~ment (50) pivote de fa×on ind~pendante par rapport ~ la sollicitation d'un ressort (56). La premire surface (44) ~tant r~duite et plac~e entre la seconde surface (52) et la molette d'allumage (20) du briquet, il faut davantage de force et d'habilet~ pour faire pivoter le premier levier destin~ ~ actionner le briquet (10).
