Definitions

  • a notch is formed in the key at the be- 52 us.
  • Cl. 431/274 "ginning of said one branch for receiving one end of 51 Int. Cl. F23q 1/02 the lover controlling thobumor valve, notably in case [58] Field of Search 431/254, 274, 275 of a lighter operating on gaseous fuel, so that the upper and lower end of said notch control the opening [56] Referen e Cit d and closing respectively of said valve.
  • the present invention relates to automatic cigarette lighters of the type comprising a pyrophoric flint for igniting the fuel, that is, wherein the actuation of the control key or like push-button member is attended by the rotation of the serrated wheel in frictional contact with the flint and by the opening of the cap or valve in the case of a lighter operating on gaseous fuel.
  • This invention provides a construction affording particularly simple manufacturing and assembling operations, wherein the serrated-wheel-driving pawl is formed unitarily with its spring and the plunger or pushbu'tton.
  • the pawl driving the ratchet associated with the serrated-wheel is obtained by injection molding from a suitable plastic material and is formed integrally (unitarily in one piece) with the control key or plunger; to this end, it comprises a pair of diverging branches strips, one branch being connected unitarily to the control key or plunger, the other or free branch having a length sufficient to impart thereto an intrinsic elasticity permitting the flexion of said other or free branch, for allowing the pivoting of the pawl finger in either direction of rotation.
  • one portion of the control key is notched and the notch thus formed is adapted to receive one end of the valve control lever, the top and bottom ends of this notch thus controlling opening and closing movement of the valve.
  • the return spring associated with the control key therefore acts at the same time as a valve spring.
  • FIG. 1 illustrates in vertical section the mechanism in its inoperative position
  • FIG. 2 shows the position of the various component elements after the control key has been depressed.
  • FIGS. 1 designates the body of the cigarette lighter
  • 2 is the control key responsive to a return spring 3
  • the serrated flint wheel 4 being associated as is conventional with pins 5 fixed to the flint wheel and forming therefrom a ratchet wheel 5 and the flint proper 6 urged by a separate spring
  • the burner and valve assembly being designated by the reference numeral 8.
  • control key 2 consists of a one-piece injection-molded element of suitable plastic material formed with an integral guide shank 9 and a V-shaped extension adapted to move in a well or notch 10 formed in the body 1.
  • One branch 11 of this V-shaped extension is adjacent the key 2 and the other branch 12 has a hook-shaped bent upper end or finger I3 constituting a pawl adapted to actuate the ratchet 5.
  • the pawl causes the ratchet 5 to rotate in the clockwise direction as seen in the drawing, thus driving the serrated wheel 4, the branch 12 of the V-shaped extension of said control key being caused to yield somewhat to per mit this rotational movement; when the control key 2 is released, it is moved upwards by the spring 3 and said branch 12 is bent again for clearing the next stud of the ratchet before resuming by its inherent elasticity its initial position (FIG. 1) to permit another actuation of the cigarette lighter.
  • a lever 14 fulcrumed to a pin 15 (which may be the same as the ratchet and wheel pivot pin) has one end engaged through a notch or aperture 16 formed in the control key 2 and in the branch 11 of the V-shaped extension of control key 2, and its other end disposed between a pair, of abutment elements 17 provided at the upper end of the burner and valve as sembly 8.
  • this lever 14 engages the bottom 16a of notch 16 and positively closes the valve of said burner and valve assembly 8, and in the operative or ignition position this burner and valve assembly 8 is brought also positively to its open position as a consequence of the pressure exerted by the opposite end 16b of notch 16 against said lever 14.
  • a cigarette lighter having a striker mechanism comprising a flint, a flint wheel rotatable against said flint to produce an ignited spark, a ratchet formed on the flint wheel, a pawl displaceable for entrainment of said ratchet to rotate said wheel, and a plunger connected with said pawl for actuating same
  • said plunger is formed in one piece with said pawl from injected molded plastic material having an intrinsic resilience and said pawl comprises a pair of mutually divergent strips 'of said plastic material unitarily joined at their junction with one of said strips unitarily joined to said plunger and the free end of the other strip formed as a finger engaging said ratchet, said strips being intrinsically flexible to permit deflection of said finger generally radially of said ratchet upon entrainment of said ratched by said pawl in a return movement of said pawl wherein said finger is cammed outwardly by
  • provement further comprising a lever pivotally
