Definitions
- This invention relates to an improvement in ignition mechanisms particularly for use in cigarette lighters.
- Prior art ignition mechanisms utilize a fingerpiece which is connected, by means of a gear segment to a carrier which straddles a flintwheel.
- the flintwheel is generally constructed with ratchet teeth molded integrally therein such that a clutch mechanism will engage a tooth and rotate the flintwheel in one direction, however, the clutch is made to slip in the opposite direction, thereby precluding rotation in the opposite direction.
- the fingerpiece is depressed and this rotates a carrier or a snuffer member. As the latter member is rotated, it carries with it a clutch which then serves to rotate the flintwheel.
- the carrier or snuffer member returns to its rest position, the clutch slips and the flintwheel remains stationary.
- the flintwheel carrier member and the fingerpiece are directly connected by a hinge which is preferably a plastic such as polypropylene, however, any flexible material will accomplish the purposes of this invention.
- the hinge may be suitably secured with the carrier member and fingerpiece by means of a suitable adhesive, but in a preferred form of the invention the fingerpiece and carrier are formed integral with the hinge.
- FIG. 1 is a side view of the upper portion of a cigarette lighter partly in section
- FIG. 2 is a side view of a cigarette lighter in the actuated position
- FIG. 3 is a sectional view showing a clutch and spark wheel.
- FIG. 1 there is shown a portion of a cigarette lighter having a housing which can be plastic or metal and can have a decorative sheath (not shown) snugly enclosing the housing 10.
- a well 11 is formed in a portion of the lighter in which there is received a burner valve 12.
- the burner valve can be any known burner valve commonly found in cigarette lighters using gaseous fuel such as butane, or the burner valve can be replaced by a wick in the case of a lighter using a hydrocarbon, such as lighter fluid, as the fuel.
- the fuel is supplied to the valve or wick by means of a fuel reservoir formed in the body of the cigarette lighter.
- a conventional flint 13 and flint spring I4 are housed in a bore 15 which is normally closed by a removable cover (not shown) on the base of the lighter.
- a conventional flintwheel 17 is mounted on an axle 16.
- the axle 16 is joumalled in opposed ears 18 formed on the lighter housing 10.
- a clutch 19 which can be stamped from a sheet of metal has an offset tang 20 which engages ratchet teeth 17a on the flintwheel in the manner of a ratchet and pawl.
- the clutch is rotatably mounted on the axle I6 and has a flat portion 21 which is engaged by a carrier 22.
- the carrier 22 is in the form of a U-shaped member which straddles the flintwheel l7 and the clutch 19. Thus, when the carrier 22 is rotated, it engages the flat portion 21 of the clutch and imparts rotation to it.
- the tang 20 on the clutch engages a tooth 17a on the flintwheel and thereby rotates the flintwheel 17.
- the clutch clips on the inclined teeth 17a so no rotation is imparted to the flintwheel 17 in the reverse direction.
- a fingerpiece 23 which can have a U-shaped cross section is connected to the carrier 22 by means of a hinge 24.
- the hinge can be integral with the carrier and fingerpiece whereby the latter elements can be molded in one piece or the hinge 24 can be glued or otherwise secured to the carrier and fingerpiece to form a unitary connection.
- the fingerpiece 23 has a lip 25 integrally formed at one end thereof. The lip extends into an opening 26 for pivotal movement therein. The lip 25 preferably does not extend fully into the opening and if desired the outer end of the opening 26 can be plugged so as to create a pleasing appearance.
- a spring 27 has one end 27a which bears on a shelf 28 on the lighter housing 10. The other end 27b of the spring 27 resiliently urges the fingerpiece 23 to its unactuated position as shown in FIG. 1.
- the user depresses the fingerpiece 23 against the bias of the spring 27. Since the carrier 22 is connected to the fingerpiece it will be urged downwardly with the forward portion of the fingerpiece.
- the carrier 22, can cover the well 11 in the same manner that a snuffer on a conventional lighter does.
- the carrier 22 grips the flat portion 21 of the clutch 19 whilst the tang '20 on the clutch engages a tooth on the sparkwheel.
- the sparkwheel rotates and rubs against the flint 13 thereby causing a shower of sparks to ignite fuel issuing from the burner valve or wick 12.
- Any known mechanical linkage can be used between the fingerpiece or carrier and the valve 12 to actuate the latter and cause fuelto emanate from the burner.
- the lighter is shown in actuated position in FIG. 2.
- an ignition mechanism comprising a housing having a burner valve fixed thereto at one end and ignition means adjacent said burner valve for igniting fuel carried within said housing, a combined carrier and fingerpiece comprising a single moldedstructure being said opening for pivotal movement therein.
- the means for igniting fuel comprises a flintwheel which is actuated by said carrier and a flint against which the flintwheel rubs to create a spark which ignites fuel emanating from the burner.
