Definitions
- Conventional ignition mechanisms of the directpercussion type use at least two springs (sometimes three or even four), i.e. a main spring which drives the striker and a return spring which restores the mechanism to its initial position when the pressure exerted on the main spring is released.
- An impacting mechanism comprises a downwardly open first casing and an upwardly open second casing engaging each other telescopically so as to be relatively slidable; relative rotation of the casings is prevented by suitable means, specifically by their prismatic shape.
- the two casings have wall portions respectively provided with first and a second slot (each duplicated on opposite sides of its casing) which partly register with each other in all operating positions.
- the second casing which in the embodiment described hereinafter is the outer one, contains a piezoelectric member forming part of an ignition circuit; an advantageously cylindrical striker is mounted above the piezo-electric member so as to be slidable inthe two casings, this striker having a transverse retaining lug in the form of a round pin traversing the registering wall slots.
- a compression spring inserted in the first (inner) casing bears upwardly against the latter and downwardly upon the striker for urging same toward the piezo-electric member.
- the first (inner) wall slot has a first lower camming edge intersecting an oppositely inclined second lower camming edge of the second (outer) slot sloping downwardly from a lateral indexing notch normally receiving the lug of the striker.
- the two intersecting edges form a downwardly pointing vertex which shifts laterally away from the indexing notch upon depression of the first casing serving as an actuator.
- the first slot, formed in the actuator also has an upper camming edge which is engageable with the lug in the course of a depression stroke and, upon an initial compression of the inserted spring, dislodges the lug from the indexing notch to enable that spring to expand whereby the striker is propelled against the piezo-electric member as its lug rides down the second, stationary, lower camming edge.
- the lug Upon the subsequent release of the actuator, the lug is intercepted by the moving first lower camming edge and is cradled in the vertex of the two camming edges whereby a component of the spring pressure is absorbed by the stationary second edge. This enables the spring to exert an upward force upon the actuator, relative to the second casing, for restoring same to normal as the lug is returned to its indexing notch by the rising and laterally shifting vertex.
- the wall slots of the two casings may be formed with access passages to facilitate the insertion of the lug.

- FIG. 2 is a view similar to FIG. 1, showing my present improvement
- FIG. 3 is a detail view of a retaining lug and associated camming slots forming part of the mechanism of FIG. 2;
- FIG. 4 is a diagrammatic illustration of the lug and part of its camming edges, drawn to an enlarged scale;

- FIG. 1 I SPECIFIC DESCRIPTION
- a known lighter comprising an inner casing l, operating as a pushbutton-type actuator, with a slot 2' dupli cated on opposite sides thereof, forming an upper camming edge 2a.
- An outer casing 3 has a slot 4' also duplicated on its opposite sides and forming a retaining or indexing notch 4a.
- a striker 5, provided with a transverse lug 6 moving in the slots 2' and 4 is loaded by a main spring 7 bearing from within upon the stop of the inner casing 1 and exerting pressure on the striker 5, the casing being urged upwardly by a return spring 8.
- Striker 5' confronts an anvil 9' constituted by a piezo-electric member.
- An ignition circuit controlled by this member has been partly shown at 16.
- the return spring 8 opposes the finger pressure exerted by the user on the actuator 1' without contributing to the acceleration of the striker. Moreover, there is no automatic decrease in the counteracting force of this spring since the latter is fully compressed when the striker is released. For the same reason, the finger pressure applied to overcome this spring force cannot be used for driving the striker.
- the torsion of the main spring 7' presses the lug 6' against the edge of the slot 4' of the outer casing 3' with considerable force during both the percussion stroke and the return stroke, thus opposing the movement of the striker by frictional resistance.
- FIGS. 2 6 parts corresponding to those of FIG. 1 have been designated by the same reference numerals, namely: the inner casing or actuator l with its slot 2 duplicated on opposite side thereof and forming a release ramp or bevel 2a the outer casing 3 with its slot 4 also duplicated on opposite sides and forming a retaining notch 4a, the striker 5 with its pin or lug 6, the percussion spring 7 and the piezo-electric anvil 9.
- slot 2 has an inclined lower camming edge 11.
- a camming edge 12 of slot 4 these two edges having relatively inverted slopes and intersecting at a vortex which progressively shifts to one side (here to the right) upon depression of the actuator.
- the edges ll, 12 bear tangentially thereon, as best seen in FIG. 4, whereby the lug is cradled in their vertex.
- the lug 6 slides down along the slot edge I1 and up along slot edge 12 until, with a rotary motion about the axis of the cylindrical striker, it engages in the notch 4a of the outer slot 4.
- p.(6,1l) is that between the lug 6 and the edge 11,
- p.(7,1) is that between the spring 7 and the part (the casing l or the striker 5) with respect to which the spring rotates.
- angles a and ,8 are difficult to make angles a and ,8 less than 20 and greater than 50.
- the angle a is greater than the angle [3, ranging for example between 25 and 40-45, whereas the value of the angle [3 may range for example between 25 and 35-40.
- the slot 2 is cut open at the top of its sloping edge 11 in order to provide a free passage 13 directed toward the bottom of the inner casing.
- the slot 4 is cut open at its upper right hand to provide a free passage 14 open toward the top of the outer casing, this passage being bounded by an inclined guide edge 15 overlying the notch 4a.
- An impacting mechanism for the ignition of a lighter comprising:
- first and second casings having wall portions respectively provided with first and second slots partly registering with each other in all operating positions;
- an ignition circuit including a piezo-electric member on the bottom of said second casing
- said slot having a first lower camming edge
- said second slot having a lateral indexing notch normally receiving said lug and a second lower camming edge sloping downwardly from said notch
- said lower camming edges having mutually inverted slopes and intersecting at a downwardly pointing vertex shifting laterally away from said notch upon depression of said first casing toward said member
- said first slot further having an upper camming edge engageable with said lug in the course of a depression stroke and upon initial compression of said spring for dislodging said lug from said notch, thereby enabling said spring to expand and propel said striker into percussive contact with said member to energize said ignition circuit, with said lug moving along said first lower camming edge, said lug being intercepted by said first lower camming edge upon subsequent release of said first casing for cradling said lug in said vertex and exerting upon said second casing
