Description
- This application claims the benefit of U.S. Provisional Application No. 60/387,561, filed Jun. 12, 2002.
- The present invention pertains to a disposable lighter that includes a safety feature which makes it difficult for a child to operate the lighter.
- A disposable gas lighter generally includes a fuel tank, a flint, a gas release and a spark wheel. Rotation of the spark wheel when in contact with the flint creates a spark which ignites gas released via the gas release, such that a flame is created. Because this flame is easy to create, a potentially hazardous situation exists when the lighter is in the hands of children. In an effort to prevent hazardous situations from arising when a lighter is in the hands of a child, various safety features have been incorporated into lighters. However, many of these safety features are either complex or do not sufficiently prevent a child from using the lighter to create a flame.
- Accordingly, there remains a need to provide a safety feature for a lighter, which is simple in its construction yet adequate to make it difficult for a child to operate the lighter.
- The primary object of the present invention is to provide a disposable lighter that includes a safety feature which is simple in construction yet adequate to prevent a child from operating the lighter to create a flame.
- In accordance with a first aspect of the present invention there is provided a lighter that includes a frame, a first turn wheel rotatably supported by the frame, a second turn wheel rotatably supported by the frame, a spark wheel constructed and arranged to be rotated by the first turn wheel but not by the second turn wheel, and a flint constructed and arranged to be contacted by the spark wheel during rotation of the spark wheel.
- Because the second turn wheel does not serve to rotate the spark wheel regardless of pressure applied to the second turn wheel , or in other words, is freewheeling relative to the spark wheel, when a user's thumb is placed on both of the turn wheels to rotate these wheels, the second turn wheel will serve no purpose in rotating the spark wheel. Accordingly, with the lighter of the present invention a force which is generally twice as much as that associated with a conventional lighter, which utilizes two turn wheels to rotate a spark wheel, is required to rotate the spark wheel. This is a safety feature of the lighter of the instant invention.
- In accordance with a second aspect of the invention, the second turn wheel is slightly larger in diameter than that of the first turn wheel, which makes it more difficult for a child to apply sufficient force to the first turn wheel so as to rotate the spark wheel.
- In accordance with a third aspect of the invention, the first turn wheel has a smooth circumferential surface, as opposed to a knurled or other gripping surface, such that additional force is required to rotate the spark wheel. The second turn wheel can have a smooth or textured circumferential surface.
- In accordance with a fourth aspect of the invention, the diameter of the turn wheels are chosen such that the spark wheel cannot be contacted and rotated directly by a user.
- In accordance with a fifth aspect of the invention, the turn wheels are provided with annular portions which extend over the spark wheel such that the spark wheel cannot be contacted and rotated directly by a user.
- FIG. 1 is an exploded view showing a preferred embodiment of a lighter of the invention.
- FIG. 2 is a cross-sectional view showing the lighter in an assembled condition.
- FIG. 3 is an enlarged and exploded view of turn wheels and a flint wheel of the lighter.
- As seen in FIG. 1, a lighter comprises a
fuel tank 2, aframe 1, acoil spring 3, aflint 4, a gas release 6, aspark wheel 7, a flame—guard 5, and turnwheels - In operation, a user turns the
turn wheels spark wheel 7 rotates. Theflint 4 is pressed into abutting engagement with thespark wheel 7 by thecoil spring 3, and friction between thespark wheel 7 and theflint 4 creates a spark during rotation of the spark wheel. Simultaneously, when the thumb leaves theturn wheels - A specific construction and assembly of the
turn wheels spark wheel 7 makes rotation of the spark wheel difficult for a child, yet easy for an adult. - As seen in FIG. 2, the
turn wheels spark wheel 7. Theturn wheel 10 has twoprojections projection 101 is smooth and rests inside theframe 1 and allows theturn wheel 10 to rotate freely with respect to theframe 1. Theprojection 102 can be geared or left smooth, and is received within an interior of thespark wheel 7. When theprojection 102 and an interior of thespark wheel 7 are both geared, this projection and the interior of the spark wheel are meshed so as to rotate together. Thesecond projection 102 can also be adhesively adhered or welded to the interior of thespark wheel 7. Accordingly, theturn wheel 10 transmits torque to thespark wheel 7 such that this turn wheel serves to rotate the spark wheel. - The
turn wheel 10 and thespark wheel 7 can be attached by any one or combination of the above-described manners, or by any other manner well known in the art. - Like the
turn wheel 10, theturn wheel 9 includes twoprojections projection 8 is smooth and rests inside theframe 1 and allows theturn wheel 9 to rotate freely with respect to theframe 1. Theprojection 15 is received within an interior of thespark wheel 7; however; theprojection 15 and the interior of the spark wheel within which this projection is received are constructed and arranged relative to one another such that theturn wheel 9 is allowed to rotate freely and independently of the spark wheel. Accordingly, theturn wheel 9 transmits no torque to thespark wheel 7 such that this turn wheel serves no purpose in rotation of the spark wheel. - Because the
turn wheel 10 is arranged to rotate thespark wheel 7, while theturn wheel 9 is arranged not to rotate thespark wheel 7, an effective area of the turn wheels utilized to rotate the spark wheel is half that of a conventional lighter, which employs two turn wheels to rotate a spark wheel. Accordingly, because the effective area to rotate thespark wheel 7 is half that of a conventional lighter, a force required to rotate thespark wheel 7, and thus create a flame, is about twice as much as that of a conventional lighter. This additional required force makes it more difficult for a child to use the lighter to create a flame. - The
turn wheels - For example, the
turn wheel 9 can have a larger diameter than that of theturn wheel 10, whereby thelarger turn wheel 9 is designed to initially make contact with a thumb pad of a user. Accordingly, when the thumb first comes into contact with thelarger wheel 9, provided is an obstacle to rotating thespark wheel 7, whereby a person with little or weak fingers will not be able to turn thesmaller wheel 10. Specifically, thelarger turn wheel 9 redirects pressure and torque away from thespark wheel 7. - That is, when the
turn wheels spark wheel 7. In this regard, because thelarger turn wheel 9 intercepts the user's thumb first, the user must then apply additional pressure to establish contact between his thumb and thesmaller turn wheel 10. This additional pressure corresponds to an additional force required to rotate thespark wheel 7, since thelarger turn wheel 9 is rotatable independently of thespark wheel 7 and does not serve to rotate the spark wheel. Therefore, only one with strength greater than that of a child will be able to actuate the lighter. The difference in diameter between theturn wheel 10 and theturn wheel 9 can be slight. - As an additional safety feature, an outer circumferential surface of the
turn wheel 10 can be smooth such that an even greater force is required to rotate this turn wheel, as compared with a turn wheel exhibiting a gripping surface such as a knurled surface, and thereby rotate thespark wheel 7. Also, an outer circumferential surface of theturn wheel 9 can be either smooth or textured. - When the diameter of the
turn wheel 9 is greater than the diameter of theturn wheel 10, and the outer circumferential surface of theturn wheel 9 is textured while the outer circumferential surface of thefirst turn wheel 10 is smooth, theturn wheel 9 will redirect even greater pressure and torque away from thespark wheel 7 such that it is even more difficult to rotate the spark wheel. Similarly, when the outer circumferential surface of theturn wheel 9 is textured while the outer circumferential surface of thefirst turn wheel 10 is smooth, with theturn wheels spark wheel 7 than would be when required both turn wheels have the same diameter and same texture for their outer circumferential surfaces. - As a further safety feature, diameters of the
turn wheels spark wheel 7, regardless of the pressure applied by the thumb. - As a further additional safety feature, the
turn wheels annular portions 103 and 109 which extend over thespark wheel 7 such that a user's thumb will not be able to make contact with and directly rotate thespark wheel 7. Theannular portion 103 ofturn wheel 10 can be provided with ridges on an interior surface thereof so as to engage with corresponding ridges on an exterior surface of thespark wheel 7. Alternatively, theannular portion 103 can be welded or adhesively bonded to thespark wheel 7. - The above-described safety features can be used separately or in combination with one another.
- While preferred embodiments of this invention have been illustrated and described, it will be obvious to those skilled in the art that various changes and modifications may be made therein without departing from the scope of the appended claims.
