Definitions

  • This invention relates to a lighter, particularly a small portable lighter of the type used to light cigarettes, cigars and other small combustible items.
  • lighters presently available such as with the prior art lighter hereinafter described it is possible for children to cause the lighter to ignite by operating an ignition device by relatively simple manual manipulation. Such ignition could also occur accidentally when the lighter is contained in a pocket, handbag or similar container. It will of course be apparent that such a situation where the lighter can be ignited by children or accidentally is undesirable and dangerous.
  • the invention consists in a lighter including a housing, ignition means for the lighter, the ignition means including a member manually moveable with respect to the housing, a lock between the manually moveable member and the housing, and release means manually operable to release the lock to allow the manually moveable member to move relative to the housing to allow or cause ignition of the lighter, the release means requiring manual movement to release the lock in a direction different to the direction of movement of the manually moveable member to allow or cause ignition.
  • the manually moveable member comprises a cap rotatably mounted on the lighter and the lock is mounted on the cap.
  • the cap is hollow and the lock comprises a bar moveable in a channel in the cap, the bar being biased to a position wherein the distal end of the bar engages or abuts part of the housing to substantially prevent movement of the cap relative to the housing.
  • the lock further comprises a release member pivotally mounted on the cap, the release member having one end extending from the cap to receive in use manual pressure and engaging the bar at or adjacent the other end thereof.
  • angle of movement between the direction of movement of the release member to cause release of the cap from the housing is substantially at right angles to the direction of the movement of the cap relative to the housing to affect the ignition of the lighter.
  • the bar is biased by a compression spring within the cap.
  • the bar has a notch in the distal end thereof to engage an adjacent edge of the housing.
  • the end of the release member is bifurcated, one arm passing each side of the spring to engage lugs on the bar.
  • Figures 1 and 2 are partial cross sections of a prior art lighter.
  • Figure 1 shows the lighter in a closed unlit or "off' position and Figure 2 shows the lighter at the end of the striking action
  • FIG 3 is a partial exploded view of parts of a lighter according to the prior art embodiment of Figures 1 and 2,
  • FIGS. 4 and 5 are partial cross sectional views of a lighter in the "off and the “ignited” position respectively in one preferred form of the present invention
  • Figure 6 is a perspective partially cut away view of a manually manipulable member for causing the lighter to ignite according to the preferred form of the invention
  • Figure 7 is an exploded view of Figure 6, and
  • Figure 8 is a view as in Figure 3 but of the lighter according to one Figures 4 and 5.
  • the prior art lighter 1 comprises a housing 2 which provides a gas chamber 3 and a compartment 4 housing piezo electric unit 5. Above the tank 3 is provided a flame guard 6 with an aperture 7 therein. Gas nozzle 10 is mounted on hollow support 11 which receives gas from the gas chamber 3 in substantially the current known manner.
  • the nozzle 10 which also is of substantially a known type carries a lighting spring 12.
  • the nozzle 10, lighting spring 12, and support 11 are held in a withdrawn position by a biasing device such as spring 13 which is compressed between shoulders 20, provided in an apertured plug 21 which is fitted to an aperture 22 in the housing 2, and a collar 23 about the member 11.
  • the gas passageways are opened by lifting the member 11 and nozzle 10 to the position shown in Figure 2 and this can be achieved by providing a lever 30 pivotally connected to the housing at 31.
  • the lever 30 has a bifurcated end providing arms 32 and 33 which engage the nozzle 10. Between the arms is provided a space 34 having a wider recess 35 in which the nozzle 10 sits.
  • the opposite end 38 of lever 30 is engaged by a pressure member 39.
  • the pressure member 39 is mounted on a downwardly depending stem 40 of a manually manipulable cap 41 which also provides a surface 42 to cover the aperture 7 when the lighter is in the "off" position.
  • the stem 40 is pivotally connected to the housing at 45 and the upper end of the stem 40 has a plug 50 which engages in an aperture 51 in a plate 52 forming the bottom part of the cap 41.
  • the cap 41 also includes an upper part 53.
  • the piezo electric unit 5 has a wire 60 which extends from the unit 5, the wire being positioned so that distal end 61 of wire 60, which provides are electrode, is positioned near the spring 12.
  • the other electrode is provided by electrical contact between the piezo electric unit 60, the pressure unit 39, the lever arm 38, the nozzle 10 and the spring 12.
  • the cap When the flame is no longer required the cap returns to the position shown in Figure 1 shutting off the gas flow and releasing pressure on the piezo electrode unit 5.
  • the return of the cap 41 is effected a biasing devices such as a spring which in the preferred form, forms part of the piezo electric unit 5.
  • the invention takes advantage of the fact that there is a space 70 in the cap 41 of the prior art construction.
  • the invention provides a lever 72 pivotally connected to the cap at 73.
  • An aperture 74 is provided in the cap 41 and a lobe 75 extends from the lever 72 outwardly through the aperture 74.
  • the lobe 75 provides a release member.
  • Pivot arms 80 on the lever 72 are held in a pair of slots 81 and 82 provided on an extension 83 to the lower cap part 52.
  • the lever 72 provides a pair of bifurcated arms 84 therefor which extend each side of a plate 85 forming part of the bottom part 52 and further extend between spaced part plates 86 and 87.
  • the members 86, 87 the member 85 and the adjacent wall part 88 of the top cap part 41 form a channel in which a member 90 may move.
  • the member 90 has a cut out depression 91 between a pair of outwardly extending arms 93.
  • the arms 84 of the lever 72 are positioned against the lower surfaces of the arms 92 and 93 (in the orientation shown for example Figure 7).
  • the member 90 at its lower end has a notch 94 which with the member 90 in the position shown in Figure 4 is positioned so that the upper edge 95 of the housing is positioned in the notch 94.
  • a biasing member such as a spring 96 is positioned in the depression 91 and abuts the under side of the top part of the cap.
  • Spring 96 in shown as a compression spring but any device capable of effecting the desired movement can be used.
  • the shape of the lobe 75 is such that in order to rotate the lever 72 a substantially downward pressure (with the lighter in the orientation shown in Figure 4 for example) must be performed. This is achieved by making the lobe 75 extend somewhat at right angles to the longitudinal axis of the lever 72. In use the lobe 75 is pushed inwardly towards the internal parts of the cap 41. This causes the lever 72 to rotate forcing the arms 84 against the undersides of the arms 93 lifting the member 90 against the biasing pressure of spring 96. Thus the member 90 is lifted clear of the edge 95 of the housing 1. The cap can then be manually rotated substantially as described in relation to Figures 1,2 and 3.
  • a lighter which has a safety features in that the cap cannot be manually manipulated until the lobe extending outwardly from the cap is pressed inwardly of the cap. It is believed that it would be difficult for children to complete both the inward pressing of the lobe and backward rotation of the cap at the same time thereby providing a substantially child proof locking device to the lighter. It is also believed that it would be difficult for these movements to occur accidentally
