TECHNICAL FIELD

The present invention relates in general to lighters and more particularly to hand held lighters that may be used to light cigars, cigarettes or pipes.

BACKGROUND OF THE INVENTION

There are a variety of different types and styles of lighters that are typically referred to as cigarette or cigar lighters. Examples of lighters are found in, for example, U.S. Pat. Nos. 6,152,725 to Lee and 6,632,082 to Smith. Although these lighters are effective for the lighting of cigars or cigarettes they are not as effective for lighting a pipe where is advisable to direct the flame downwardly into the pipe bowl.

DETAILED DESCRIPTION

Reference is now made to the accompanying drawings for a preferred embodiment of the present invention. The lighter that is described herein may be used for lighting cigars, cigarettes or other items, but is particularly suited for lighting a pipe in that it is provided with an extendable support tube that allows the nozzle to be readily re-directed by being bent in multiple directions including a reversed direction. For the pipe application one can easily hold the lighter housing basically upright while at the same time bending the nozzle downwardly into the pipe bowl to facilitate a lighting of the pipe.

To provide the improved operation of the present invention a flexible support tube 40 is provided that is adapted to extend from the housing and has supported at its distal end the nozzle head 50. The tube 40 is shown in the drawings in both an extended (FIGS. 2 and 4) and non-extended (FIGS. 1 and 3) position. The flexible support tube 40 is preferably made of metal, may be formed in separate sections that enable a flexing or bending action and is hollow through its length. The flexible support tube 40 has a nested position in which it is disposed within the housing 12 and an extended position in which the flexible support tube 40 extends from the housing enabling the flexible support tube to be bent in multiple directions for directing the nozzle head 50. Refer to the plan view of FIG. 6.

Referring to the drawings there is illustrated a lighter 10 according to the present invention which includes a housing 12. There may be a cap provided over the housing but such a cap is not show herein. The housing 12 may be constructed of metal and may be provided in multiple pieces that are secured together. Within a bottom part of the housing is disposed a fuel reservoir 14 that contains a standard lighter fluid fuel. A filler valve 18 is illustrated at the bottom wall of the housing. The lighter fluid is inserted through the filler valve 18. The bottom wall of the housing is also shown as having a flame adjuster 16.

The top of the housing supports an actuation button or switch 20. The actuation button 20 controls both an ignition member for generating a spark to ignite the fuel, and a valve for controlling the fuel flow from the reservoir. By depressing the button 20 the valve is opened and the ignition source is activated. The actuation button 20 is depressed to operate the lighter and has a biasing means (not shown) associated therewith to return the actuation button to its extended or upper position. Although the actuation button 20 is illustrated at the top of the housing it is understood that it could also be mounted at other locations of the housing such as at a sidewall of the housing.

As mentioned previously, there is provided an ignition member. This is shown in the drawings by the spark ignition mechanism or member 26 which is also disposed within the housing 12. The ignition member 26 is for generating a spark in close proximity to the nozzle head 50 upon actuation of the actuation button or switch 20, as will be described in greater detail below. An ignition wire 28 extends from the ignition member to an ignition wire tip at the nozzle 50. Many types of spark ignition mechanisms are known in the art. Examples of suitable ignition mechanisms include, but are not limited to, a piezoelectric device, which is preferred in the present embodiment. The ignition wire 28 is shown extending from the ignition source 26 through the flexible support tube 40 to the nozzle head 50. The activation of the ignition means can occur whether the flexible support tube is in the extended or nested position or at positions therebetween. For an illustration of the use of an ignition wire and its relationship to a nozzle refer to U.S. Pat. No. 6,632,082 which is hereby incorporated by reference herein in its entirety. For a relationship between a piezoelectric device and an actuation button refer also to U.S. Pat. No. 6,997,700 which is also hereby incorporated by reference herein in its entirety.

As mentioned before, the actuation button 20 also operates the fuel valve. This is shown schematically in the drawings by the valve 24 that is operated to couple the fuel from the reservoir 14 to the fuel line 30. The fuel line 30 connects through the flexible support tube 40 to the nozzle head 50. As shown in the drawings both the fuel line 30, as well as the piezoelectric wire 28 are formed with a sufficient loop so that they are not pulled or pinched as the flexible support tube transitions between its opposite positions. The hollow flexible support tube 40 is mounted or contained within the hollow guide tube 42. The guide tube 42 extends vertically within the housing 12 and defines an output port 44 through which the flexible support tube 40 extends. The guide tube 42 is provided with a longitudinally extending slot 43 that allows the fuel line 30 and the piezoelectric wire 28 to freely move as the flexible support tube moves between its opposite positions.

In the nested position of the flexible support tube 40 the tube is disposed fully within the guide tube 42. Alternatively, in the extended position of the flexible support tube 40, it is fully extended with only the base thereof remaining at the top of the guide tube as illustrated. The flexible support tube 40 is manually nested or inserted and extended relative to its guide tube by grasping the nozzle head, and may also be withdrawn to other positions between fully nested and fully extended. Moreover, the flexible support tube 40 is also capable of bending in about all directions as shown in FIG. 6 in dotted outlines. This bending includes a reverse bend so that the flame can be directed downwardly if need be, as shown in FIG. 5.

Having now described a limited number of embodiments of the present invention, it should now be apparent to those skilled in the art that numerous other embodiments and modifications thereof are contemplated as falling within the scope of the present invention as defined by the appended claims. For example, many different types of lighter constructions are contemplated as falling within the scope of the present invention, such as normal flame lighters as well as torch or windproof lighters. The ignition source can also be of different types.
