摘要:
A cigarette lighter with an ignition circuit including a piezoelectric crystal is actuated by a key pivotally supported on a housing wall for manual swinging in a predetermined direction from a normal position. The key carries two pairs of studs projecting from opposite sides thereof, the studs on each side being eccentrically disposed in angularly offset relationship as seen in the direction of swing. A striker confronting the piezoelectric crystal, urged toward the latter by a compression spring, is tied to a wire link having a hook-shaped extremity which straddles the key and engages the first pair of studs in the normal position. When the key is swung into its working position, these first studs initially entrain the link to compress the spring; toward the end of the swing, the second pair of studs bear upon the link and deflect it out of engagement with the first studs whereby the spring expands and drives the striker against the crystal.

In this automatic cigarette lighter a restoring spring for an operating key or pushbutton is also adapted, with an upper, straight end disposed under the head of the operating member to act as a pawl for actuating a ratchet associated with a serrated sparkling wheel, this spring end having its maximum flexibility in the normal position of the operating member and its maximum rigidity in the depressed position of that member. In a lighter operating on gaseous fuel a notch is formed in the operating member and engaged with play by one arm of a two-armed lever connected to a burner and valve assembly, the upper and lower ends of that notch controlling the opening and the closing, respectively, of the burner valve.
