Gas-filled childproof lighter

A gas-filled childproof lighter, of the type comprising a body with means for producing sparks and in which means for opening the valve consist of a tilting lever articulated to a fixed pin orthogonal to the axis of a burner valve, one end of which lever, in the shape of a fork or a ring, is engaged under a collar of the burner valve and the other end, or actuation end, of which is intended to be actuated by the user by being pushed in the direction of the body of the lighter, counter to the force of a return spring, the means for producing sparks themselves being independent or combined with the lever for opening the valve, and in which there are combined with the tilting lever means for neutralizing this lever, which means consist of a member movable between an active neutralization position, in which it prevents the actuation of the control lever for opening the valve, having a part located under the rear actuation end of this lever, and a nonobstructing position in which allows this actuation, this member, which can be displaced, manually, by the user, from its active neutralization position to its nonobstructing position, and which is normally kept in the neutralization position, being, moreover, arranged so as to be returned automatically into the neutralization position after actuation of the lighting mechanism, wherein the member for neutralizing the tilting lever consists of a pusher mounted so as to slide against the lower face of the rear actuation end of the control lever, whose movement it follows, and movable between a withdrawn active position in which, since it is projecting beyond the rear end of the control lever, a part integral with the body of the lighter is situated just below it, making any maneuver of the control lever impossible in the direction for opening the valve, and an advanced and nonobstructing position, in which the aforementioned part of the body of the lighter is no longer in the path described by the pusher when the control lever is maneuvered in the direction for opening the valve, making this maneuver possible, means being provided for ensuring that the pusher is momentarily kept in the nonobstructing position before actuation of the control lever and other means being provided to ensure that it returns to the active neutralization position immediately after this actuation.
