CA 2280919

An apparatus is disclosed for providing more uniform lighter spark wheel actuation. Uniform actuation is facilitated in the apparatus according to the invention by reducing the formation of deep grooves and high ridges in the flint. In one embodiment of the invention, a spark wheel coil (10) formed from wire having at least one substantially flat side is utilized to reduce ridge formation. The spark wheel coil (10) includes pitting in a transversal direction made on the outer surface of the coil (10). The pitting forms projections (12) which protrude from the core of the coil (10) and which, when contacting a pyrophoric flint (40) while the coil spring is rotated about its axis, produce a tangential cutting across the pyrophoric flint (40) to emit an ignition spark.

L'invention concerne un appareil permettant d'actionner de façon plus homogène la molette de production d'étincelles d'un briquet. A cet effet, on réduit la formation de rainures profondes et de crêtes élevées dans la pierre à briquet. Dans un mode de réalisation préféré de l'invention, une bobine de la molette de production d'étincelles, formée à partir d'un fil métallique présentant au moins un côté pratiquement plat, est utilisée pour réduire la formation de crêtes. Cette bobine comprend des cratères dans une direction transversale, réalisés sur la surface extérieure de la bobine. Ces cratères forment des parties saillantes qui dépassent du noyau de la bobine et qui, lorsqu'elles sont en contact avec une pierre à briquet pyrophorique au moment où le ressort de la bobine tourne autour de son axe, produisent une entaille tangentielle à travers la pierre à briquet pyrophorique afin d'émettre une étincelle d'allumage.
