ABSTRACT:
A lockable spark generating device for a lighter includes a supporting frame, an ignition means and a locking means. The supporting frame is disposed on a gas reservoir having a valve which is actuated by a gas lever pivotally mounted on the supporting frame for releasing gas therefrom. The ignition means comprises a flint supported by a resilient element and a spark wheel which is rotatably mounted on the supporting frame for movement between a locking position and an ignition position. The spark wheel has a knurling surface adapted for contact by a user and rotatable by the user and a striking surface in contact with the flint. The flint is retained urging against the striking surface of the spark wheel by means of the resilient element for generating sparks directed toward the valve when the striking surface is driven to rotate against the flint by moving the knurling surface in the direction of the gas lever by the user. The locking means comprises at least a locking pawl member disposed on the supporting frame having a pawl surface adapted to engaged with the knurling surface of the spark wheel when the spark wheel is positioned in the locking position normally for stopping any rearward rotation movement of the spark wheel to prevent unexpected ignition, thereby rendering the lighter children resistant.
