Abstract: A safety mechanism for lighters includes a lighter body having a safety lever that is actuated from outside the body by acting upon a tongue passing through a L-shaped window in the body. The safety lever, which is mounted as a torsion spring, normally occupies a position in the L-shaped window with the tongue at the end of the horizontal leg of the window. In that position, the pushbutton and the upper edge of the safety lever are in substantial abutment and operation of the lighter is not possible. When the tongue is moved to the other end of the L-shaped window, the tongue is in alignment with a recess provided in the pushbutton such that the pushbutton is free to move. After lighting is accomplished and the pushbutton is released, the tongue recovers automatically to the safety position.

Abstract: Of the type that include two telescopic bodies (1, 2) aided by a spring (17) which keeps them extended, there being inside the former the piezoelectric element (3) immobilized between an anvil (4) and the stop piece (6) upon which a firing hammer (8) strikes generating the spark.The outside telescopic body (2) includes a pair of ribs (22) which emerge from diametrically opposite points of the cylindric surface of its axial recess, which guide the telescopic displacement of the other body (1) upon introducing themselves in respective longitudinal grooves (12) of the body, in which the diametric projections (10) of the guide of the firing hammer (8) play.The body (2) has in its end opposite the emergence of the body (1) with a widened axial recess where there is a pair of confronting windows in which a cover (14) is secured in which springs (13, 17) which aid the firing hammer and telescopic body (1) are included.

Abstract: A device for producing ignition sparks when falling on a pyrophoric flint includes a coil spring having at least one coil which is provided with a pit in a transversal or inclined direction on the outer longitudinal line of the coil. The pit is formed of "saw-teeth" type projections which protrude from the original core of the coil, thereby forming on the outer surface of the coil spring cutting projections which, when falling on a pyrophoric flint applied to the outside of the coil spring and when the coil spring turns about its axis, produce a tangential hauling of the pyrophoric flint thereby emitting an ignition spark.
