Description

BACKGROUND OF THE INVENTION

Field of the Invention

The embodiments of the present invention relate to a cigarette lighter, and more particularly, the embodiments of the present invention relate to a cigarette lighter for safely moving through dangerous areas and method of use.

DESCRIPTION OF THE PRIOR ART

Liquid fuel burning cigarette lighters generally include reservoirs within the lighter housings to contain the fuel and prevent inadvertent leaking. Numerous types of mechanisms and methods are known to release the fuel from the reservoirs in a controlled manner and to ignite the fuel for lighting a cigarette, cigar, or smoking pipe, however, there exists a need for removing the fuel cartridge from the lighter safely.

Numerous innovations for cigarette lighter usable devices have been provided in the prior art, which will be described below in chronological order to show advancement in the art, and which are incorporated herein in their entirety by reference thereto. Even though these innovations may be suitable for the specific individual purposes to which they address, nevertheless, they differ from the embodiments of the present invention.

U.S. Pat. No. 2,710,533 to Fischer et al

U.S. Pat. No. 2,710,533—issued to Fischer et al. on Jun. 14, 1955 in U.S. class 67 and subclass 7.1—teaches a ignition lighter mechanism that can be attached to a cartridge containing a liquified fuel under pressure, such as, butane, propane, and similar fuels that are adapted to turn into a gas upon being released into the atmosphere from the reservoir or container. A feature resides in the combination of a cartridge that carries a supply of liquified fuel, and the neck of which, is threaded so as to receive the lighter unit that includes a fuel release valve that permits the fuel from the cartridge to leak slowly through the same, a snufier cap, and a pyrophoric flint, and abrading wheel to direct a spark over the nozzle of the lighter unit. This combination of elements including mainly the cartridge holding a supply of compressed fuel for the flame of the lighter and the lighter unit provide the essential elements of the combination that produce a lighter, either of the pocket type or the desk type.

U.S. Pat. No. 4,330,954 to Lonsmin

U.S. Pat. No. 4,330,954—issued to Lonsmin on May 25, 1982 in U.S. class 40 and subclass 486—teaches a cigarette lighter cover that is a novelty sleeve for the cigarette lighter, and which has a tubular body portion with a hollow interior space sized to receive the body of the cigarette lighter of conventional design. One end of the body portion is closed off to form a bottom end of the sleeve. The other end of the body portion is open to receive the cigarette lighter. An image-presenting assembly is situated on one side of the sleeve and includes a filmstrip. Opaque portions of the filmstrip have a desired color to provide a portion of an image and a translucent portion has the remaining portion of the image that is caused to appear and disappear. A dark background is situated behind the translucent portion of the filmstrip and a light colored shield is positioned behind the filmstrip, between the filmstrip and the dark background. The shield has a handle for moving the shield to, and from, a position behind the portion of the image defined by the translucent portion of the filmstrip, thereby to cause it to appear when the shield is moved therebehind.

U.S. Pat. No. 3,414,364 to Bert

U.S. Pat. No. 3,414,364—issued to Bert on Dec. 3, 1968 in U.S. class 431 and subclass 143—teaches a pyrophoric cigarette lighter having a disposable fuel container which itself constitutes the main body of the lighter, complemental securing apparatus forming part of the container and cooperating with corresponding complemental securing apparatus carried by a separate igniting mechanism and a separate pressure reducer and burner unit for operatively and detachably affixing the unit and the mechanism to the disposable container. Numerous gas lighters having a disposable refill cartridge allow the user to change not only the cartridge or container, but also one of the components of the lighter. These components, however, form complex assemblies and consequently expensive units. Generally, the pressure reducer and burner unit is either an integral part of the igniting mechanism or is permanently attached to the disposable container, while the igniting mechanism forms a permanent unit with the body of the gas lighter and with the flint-carrying tube and the like.

U.S. Pat. No. 5,460,520 to Lin

U.S. Pat. No. 5,460,520—issued to Lin on Oct. 24, 1995 in U.S. class 431 and subclass 255—teaches a gas torch including a container that holds a disposable gas lighter, and a casing detachably connected to the container, at a top thereof to hold an electric ignition device. The casing has a horizontal partition wall to hold a gas flow guide and a flame nozzle.

The inside unit has an interior chamber, a wick, a flint, a flint position apparatus positioned in the interior chamber, a flint wheel, and a chimney. The lighter has a disposable fuel cell containing lighter fuel. The fuel cell is designed to fit within the interior chamber and to not interfere with the flint position apparatus. When the container is to be used in a windproof lighter, it has an opening that receives the wick. The wick extends into the interior chamber and has a component that is larger than the opening so that when the container is properly positioned within the interior chamber, the component secures the container in position and prevents accidental spillage of the lighter fuel.

U.S. Pat. No. 6,733,277 to Huang

U.S. Pat. No. 6,733,277—issued to Huang on May 11, 2004 in U.S. class 431 and subclass 153—teaches a locking lever for a lighter actuation mechanism that prevents the actuator from operating when in a locked position. Operation of the lever causes a portion of the lever to be withdrawn from a housing portion of the lighter and permits the actuator to be moved and operated. The lever mechanism is spring-loaded so that the end of the lever normally extends into the lighter housing in a locked position. A top portion of the lever is flattened and curved to prevent intuitive operation while permitting easy disengaging of the locking mechanism. An end portion of the locking lever has a sloped profile to move the lever in an upward direction when the actuator device is returned to a normal position, after operating the lighter. When the lighter actuator returns to the normal position, the spring-loaded lever again extends into the housing of the lighter to prevent accidental operation. The locking lever is accessible through a top surface of the lighter actuator to permit the lighter to be unlocked and actuated with a simple motion.

U.S. Pat. No. 6,939,128—issued to Suzuki et al. on Sep. 6, 2005 in U.S. class 431 and subclass 130—teaches an ignition operation mechanism for slide type lighters that is capable of preventing accidental ignition or ignition due to erroneous use or the like while maintaining good operability. Pivots for an operating cap are made substantially circular in cross section and so sized as to form a vertically movable clearance as they are locked to a support section in the lighter main body. The pivots for the operating cap are normally urged to be positioned in the upper region of the interior of a support section by the spring force of a return spring for a piezoelectric mechanism. The operating cap is slid until a lever member, strikes the lighter main body, and no longer moves in the slide direction, from which state, the operating cap is pressed downward, whereby the pivots move downward within the support section, whereupon pressing levers reach the operation stroke that overcomes the piezoelectric mechanism producing a discharge voltage to enable ignition.

United States Patent Application Publication Number 2008/0044784—to Park

United States Patent Application Publication Number 2008/0044784—published to Park on Feb. 21, 2008 in U.S. class 431 and subclass 344—teaches two basic components, a housing and a fuel cartridge. The housing may include multiple pieces. The fuel cartridge is easy to remove from the housing without the use of any tools. Thus, an empty fuel cartridge can quickly be replaced with a full one by the user. Replacing the fuel cartridge, rather than refilling it, prevents the user from coming into contact with lighter fuel. A worn or damaged housing may be removed from the lighter by the user and replaced with a new housing. All or part of the housing may also be replaced with a housing having a different outward appearance. A user can thus change the appearance of his or her lighter by changing housings, rather than having to purchase multiple lighters. The housing may include surface features, such as, bosses, ribs, and/or tensioning springs to tighten a fit of the housing and prevent spontaneous separation. The surface features may also protect the appearance of the housing.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Introductory

Referring now to the figures, in which like numerals indicate like parts, and particularly to FIGS. 1 and 2, the cigarette lighter of the embodiments of the present invention is shown generally at 10 for safely moving through dangerous areas 12.

Overall Configuration of the Cigarette Lighter 10

The overall configuration of the cigarette lighter 10 can best be seen in FIG. 3, and as such, will be discussed with reference thereto.

The cigarette lighter 10 comprises a lower section 14, an upper section 16, and a fuel flow controller 18. The upper section 16 is replaceably attached to the lower section 14. The fuel flow controller 18 interfaces with the lower section 14 and the upper section 16 and controls a flow of a fuel 19 from the lower section 14 where stored to the upper section 16 where ignited.

Specific Configuration of the Lower Section 14

The specific configuration of the lower section 14 can best be seen in FIG. 3, and as such, will be discussed with reference thereto.

The lower section 14 is generally rectangular-shaped and hollow, and has a top 20 and a side 22.

The top 20 of the lower section 14 is open to communicate with the upper section 16 while holding the fuel flow controller 18 in position, and is reduced laterally to form an axial male flange 24 therearound.

The lower section 14 is a replaceable canister 26 that contains a reservoir 28 for storing the fuel 19 therein.

The lower section 14 has a spring-loaded ball-release 30 that is biased outwardly, and is disposed on the axial male flange 24 of the top 20 of the lower section 14.

Specific Configuration of the Upper Section 16

The specific configuration of upper section 16 can best be seen in FIG. 4, and as such, will be discussed with reference thereto.

The upper section 16 is generally rectangular-shaped and hollow, and has a top 31, a bottom 32, an initial working side 34, a terminal worked side 36, and a corner 38 where the initial working side 34 of the upper section 16 meets the top 31 of the upper section 16.

The corner 38 of the upper section 16 is removed, leaving a portion 40 of the initial working side 34 of the upper section 16 in tact. The portion 40 of the initial working side 34 of the upper section 16 has a through bore therethrough 42.

The bottom 32 of the upper section 16 is open to communicate with the lower section 14, while selectively and frictionally receiving the axial male flange 24 of the lower section 14, and the through bore 42 of the portion 40 of the initial working side 34 of the upper section 16 selectively receives the spring-loaded ball-release 30 of the lower section 14.

The spring-loaded ball-release 30 of the lower section 14 is pushed in and out of the through bore 42 of the portion 40 of the initial working side 34 of the upper section 16 preventing spontaneous separation and the upper section 16 is then pulled up and off, thereby removing the upper section 16 from the lower section 14 and discarding the lower section 14 so that the upper portion can be moved safely through the dangerous areas 12.

The upper section 16 further has a trigger 44. The trigger 44 of the upper section 16 is movably mounted in the corner 38 of the upper section 16.

The upper section 14 contains scaffolding 46. The scaffolding 46 of the upper section 16 is fixedly attached within, and to, the upper section 16. The scaffolding 46 of the upper section is generally L-shaped, extends downwardly from the top 31 of the upper section 16 in a vertical portion 47v, and laterally to the corner 38 of the upper section 16 in an horizontal portion 47h.

The upper section 14 further contains a trigger post 48. The trigger post 48 of the upper section 16 is vertically oriented, moves vertically through the horizontal portion 47h of the scaffolding 46 of the upper section 16, and has an upper end 50 and a lower end 52.

The upper section 14 further contains a trigger connecting rod 54. The trigger connecting rod 54 of the upper section 16 is horizontally oriented and extends fixedly from, so as to move with, the upper end 50 of the trigger post 48 of the upper section 16 fixedly to, so as to move with, the trigger 44 of the upper section 16.

The upper section 14 further contains a coil spring 56. The coil spring 56 of the upper section 16 coils around an upper portion 58 of the trigger post 48 of the upper section 16. The upper portion 58 of the trigger post 48 of the upper section 16 extends from the trigger connecting rod 54 of the upper section 16 to a spring seat 60 of said horizontal portion 47h of the scaffolding 46, so as to normally bias the trigger 44 of the upper section 16 upward via the trigger connecting rod 54 of the upper section 16, so when the trigger 44 of the upper section 16 is pressed downwardly, the coil spring 56 of the upper section 16 compresses as the trigger post 48 of the upper section 16 moves downwardly, and when pressure is removed from the trigger 44 of the upper section 16, the coil spring 56 of the upper section 16 biases the trigger 44 of the upper section 16 back upwardly to normal.

The upper section 14 further contains a fuel-feed conduit 62. The fuel-feed conduit 62 of the upper section 16 is vertically oriented, hollow, is disposed parallel to, and inwardly of, the terminal worked side 36 of the upper portion 16, and includes a lower portion 64 and an upper portion 66.

The lower portion 64 of the fuel-feed conduit 62 of the upper section 16 has a lower end 68 and an upper end 70, while the upper portion 66 of the fuel-feed conduit 62 of the upper section 16 has a lower end 72 and an upper end 74.

The lower end 68 of the lower portion 64 of the fuel-feed conduit 62 of the upper section 16 has a reduced portion 75.

The upper end 74 of the upper portion 66 of the fuel-feed conduit 62 of the upper section 16 is vertically affixed to, and accessible via, the top 31 of the upper section 16, with the lower end 72 of the upper portion 66 of the fuel-feed conduit 62 of the upper section 16 and the upper end 74 of the upper portion 66 of the fuel-feed conduit 62 of the upper section 16 both being open.

The lower end 72 of the upper portion 66 of the fuel-feed conduit 62 of the upper section 16 telescopically receives the upper end 70 of the lower portion 64 of the fuel-feed conduit 62 of the upper section 16 so as to allow the lower portion 64 of the fuel-feed conduit 62 of the upper section 16 to slide up and down in the upper portion 66 of the fuel-feed conduit 62 of the upper section 16.

The upper end 74 of the upper portion 66 of the fuel-feed conduit 62 of the upper section 16 is an output hole 76 for a flame for igniting a cigarette.

The upper section 16 further contains a trigger linkage 78. The trigger linkage 78 of the upper section 16 is generally horizontally oriented and has an initial working end 80 and a terminal worked end 82. The initial working end 80 of the trigger linkage 78 of the upper section 16 is affixed to, depends from, and moves up and down with, the trigger 44 of the upper section 16.

The trigger linkage 78 of the upper section 16 extends continuously from, is affixed to, and moves up and down with, the lower end 52 of the trigger post 48 of the upper section 16.
