<p>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).</p> |
