Definitions

  • This invention relates to child-resistant utility lighters .
  • Utility lighters are very useful and have become quite prevalent in modern society.
  • Utility lighters of the type described herein generally contain a handle and an elongated nozzle pipe .
  • the shape and operation of utility lighters allow for several advantages over normal means of producing a f lame .
  • Most signi f icantly due to the elongated nature of the nozzle pipe , uti lity lighters enable the operator to stand a safe distance away from the object to be ignited before actuating the lighter, thus avoiding a large number of potential accidents.
  • utility lighters allow a flame to be produced in hard-to-reach or narrow places, where the human hand holding a match would not normally fit. Still, in the hands of children, or others who do not know how to safely and properly operate the lighter, such lighters are as dangerous as any other spark and/or flame-producing device. Therefore, a need has been realized to equip utility lighters with safety features that minimize Page 2
  • the invention described herein offers such a combination.
  • the invention requires that an ignition resistant button, located on the exterior surface of the handle be depressed simultaneously with the trigger before a flame can be produced. In this way, young children are coaxed into believing that they can operate the lighter in the usual way, i.e., by pressing the trigger. However, such operation will produce neither a spark nor a flame.
  • the Page 4 Given the position of the ignition resistant button relative to the trigger, the Page 4
  • simultaneous operation of both the trigger and the ignition resistant button can be performed by one hand of the intended adult user for ease of operation.
  • the smaller size of a child's hand makes it difficult for a child to engage both the ignition resistant button and the trigger simultaneously with just one hand.
  • the ignition resistant mechanism automatically engages, eliminating the need to remember to re-lock the lighter.
  • the primary object of this invention is to provide an automatic safety mechanism for utility lighters so that children or inexperienced users will be less likely to inadvertently activate the lighter.
  • a safety feature is especially important because young children often play with lighters as toys and because lighters have mechanically oveable parts that make them attractive to children as toys.
  • the automatice safety mechanism releaves the user of the burden of having to remember to activate the safety mechanism after each use.
  • Another object of the present invention is to prevent the generation of not only a flame, but even a spark.
  • a lighter where only the fuel-release mechanism is inhibited in the locked state, young children playing with the lighter can still use the lighter to create sparks.
  • Page 5 As noted previously, in a lighter where only the fuel-release mechanism is inhibited in the locked state, young children playing with the lighter can still use the lighter to create sparks. Depending on the child's surroundings, Page 5
  • a further object of the invention described herein is to provide an improved device for maximizing safety in utility lighters without compromising ease of use. To this end, the invention permits the intended adult user to operate the utility lighter with only one hand.
  • the invention meets its objectives by providing an ignition resistant button that must be depressed simultaneously with the trigger to produce a spark and a flame.
  • the ignition resistant button is positioned on the exterior surface of the handle at a location behind the trigger. Typically, a young child will attempt to activate the lighter by depressing only the trigger.
  • the placement of the ignition resistant button permits the intended adult user to use only one hand when operating the lighter, however, it is difficult for a child with smaller hands than an adult to depress both the ignition resistant button and the trigger with one hand.
  • the portion of the ignition resistant button that is exposed is located on exterior surface of the lighter housing at a position behind the trigger. As such, the smaller size of a child's hand does not permit a child to depress the ignition resistant button and the trigger simultaneously.
  • the invention disclosed herein achieves its safety objectives without making operation of the lighter any more cumbersome than a regular utility lighter with no safety feature.
  • the ignition trigger is Page 7

  • FIGS 1 through 4 (b ) generally illustrate the best mode of the present invention, a multi-purpose gas lighter with igni tion resistant function .
  • the lighter is constructed of a handle (H) , a nozzle pipe (NP) attached to the forward end of the handle (H) via engagement means , a actuating trigger (T) , a piezoelectric unit (PU) , a nozzle lever (NL) that translates the motion of the trigger (T) to open a nozzle (N) , and a fuel reservoir
  • the handle (H) is comprised of two shells (C) , cut along the longitudinal axis of the lighter, having an exterior surface and an internal cavity.
  • Fig. 2 shows one of these shells (C) separated from the other shell and exposing the internal structure of the lighter.

  • N nozzle
  • NL nozzle lever
  • PU piezoelectric unit
  • the lighter is equipped with a fuel reservoir (R) , having a forward end and a rear end, located near the back end of the handle (H) .
  • a fuel-release nozzle (N) is attached to the forward end of the fuel reservoir (R) and controls the emission of fuel. This nozzle (N) is spring loaded so that it is normally urged to a closed position.
  • a fuel tube (W) is connected to the nozzle (N) and extends the length of the nozzle pipe (NP) to a discharge nozzle
  • a nozzle lever (NL) engages the nozzle (N) and translates the motion of the trigger to open the nozzle (N) and release fuel.
  • a trigger (T) having an interior portion and operational portion, is slidably mounted between the two shells of the handle (H) and is allowed to slide back and forth along the longitudinal axis of the lighter.
  • the interior portion has means for engaging the nozzle lever
  • PU which creates an electric discharege that is carried to the free end of the nozzle pipe (NP) via a wire (PW) to ignite the released fuel.
  • a protruded lever (Tl) is formed on the interior portion in a parallel direction with the trigger (T) .
  • the operational portion is opposite the interior portion and exposed to the user.
  • the new and novel improvement of the present invention includes the addition of an ignition resistant function.
  • One of the primary elements of the ignition resistant function is a U-shaped ignition resistant button (10) .
  • the ignition resistant button (10) has a finger pad and at least two supporting legs.
  • the finger pad is exposed on the exterior surface of the handle (H) from an air hole
  • the supporting legs are contained within the internal cavity of the handle (H) and flare outward to create ledges that prevent the ignition resistant button (10) from falling out of the air hole (Cl) .
  • Springs (12) are attached to the supporting legs urging the ignition resistant button (10) upward towards an "off" position.
  • a stopper (11) is attached to at least one supporting leg and is positioned parallel to the protuded lever (Tl) .
  • the protruded lever (Tl) when the lighter is not in use, the protruded lever (Tl) is parallel and aligned with the stopper (11) . In this position, if a user depresses the trigger (T) without depressing the ignition resistant button (10), the protruded lever (Tl) abuts the stopper
  • the protruded lever (Tl) when the trigger is depressed, the protruded lever (Tl) does not abut the stopper (11) and the trigger (T) activates the piezoelectric unit (PU) and engages the nozzle lever (NL) to open the nozzle (N) and release fuel.
  • the springs (12) urge the ignition resistant button (10) upward such that the stopper (11) is re-aligned with the protruded lever (Tl) .
  • the position of the stopper (11A) and the protuded lever (T2) are slightly modified.
  • the stopper (11A) is positioned between the supporting legs of the ignition resistant button (10) and is parallel to the protruded lever (T2) .
  • the protuded lever (T2) is located at the rear of the internal portion of the trigger (T) and extends parallel towards the stopper (11A) .
  • the lighter which impedes the ability of small children to use the lighter.
  • the position of the ignition resistant button relative to the trigger is comfortably positioned for use by the intended adult user, a child with smaller hands will not be able to depress the ignition resistant button and the trigger with one hand.

Abstract

Cet allume-gaz sécurité enfants, tel que montré sur les figures 1 à 5 présente une construction classique d'allume-gaz dont l'amélioration réside en un levier saillant (T1, T2), en un bouton (10) en forme de U opposant une résistance à l'allumage, en une butée (11, 11A) et en un ressort (12). La butée (11, 11A) et le levier saillant (T1, T2) sont alignés pour être parallèles l'un avec l'autre et empêcher la production d'une étincelle et l'apport de carburant tant que le bouton (10) de résistance à l'allumage n'est pas enfoncé simultanément. Après utilisation de cet allume-gaz, le ressort (12) repousse le bouton (10) vers le haut, restaurant automatiquement la fonction de résistance à l'allumage.
