This invention relates to child-resistant lighters.
FLINT GAS LIGHTER WTfFI IGNTITON RESISTANT MECHANISM
1. TECHNICAL FIELD:
This invention relates to child-resistant lighters.
2, BACKGROUND ART:
The simplicity and ease in operating a standard lighter poses a potential fire hazard when it falls in the hands of children. As an alternative, a number of lighters have been introduced to consumers with various ignition resistance devices to prevent use by children. Figure 6 is an example of an alternative lighter with an ignition resistance device. The ignition resistance device depicted on Figure 6 utilizes a protuded ledge, stopper, and compression lever to deter the movement of the nozzle lever. During operation, the com ression lever is p pushed down pressing the stopper inward causing the protuded lever to be wedged against the nozzle lever and preventing the nozzle lever to move downward. The benefit of using this type of lighter equipped with a compression lever as an ignition-deterrent device is its effectiveness in preventing children's use.
The downside, however, is the inconvenience of having to move the compression lever upward each time when a user needs to ignite the lighter. In addition, the complicated structure increases the cost of manufacture.
In an effort to solve the problems above, other types SUBSTITUTE SHEET (RULE 26) of lighters were introduced that contained ignition resistance devices but were simplier (One Touch) in operation. Figure 7 illustrates an example of such a One Touch Lighter. Tlie Once Touch Lighter depicted in Figure 7 util.i_zes an elastpc wheel located on top of the spark wheel and connected to the metal cap. During operation, a user must: apply enough Force to the elastic wheel tc> turn the side wheel. t:o create a :;park.
The advantage of using a C>n.e Touch lighter is that the user can produce an ignition with one-touch operation.
However, it is inconvenient t.o use in the sense that a user has t:c apply more Force to the side wheels than he would with the standard lighter. Fur thermo:re, given that t:ze metal cap and ~f.e elastic wl~ee_1_ Gre positioned at: t::le point where the flame is emitted, there is a potential for the user's thumb and f=fingers to be burned .

4. BRIEF DESCRIPTION OF DRA4JINGS:
The advantages of the invention can be more clearly understood by reference to the drawings in which:
Figure 1 is a perspective view of the invention Figure 2 is a cross-sectional view of the area specified as 2-2 in the Figure 1 Figure 2A is a magnified cross-sectional view of the ignition resistance button as specified as area 2A in the Figure 2 Figure 3 is a profile view of the invention while in use figure 4 is a perspective view of a conventional gas lighter Figure 5 is a profile view of a conventional gas lighter illustrating the internal mechanical structure Figure 6 is a perspective view of a prior art lighter with an ignition resistance device Figure 7 is a perspective view of a prior art lighter with a one touch ignition resistance device Figure 8 is a profile view of a prior art lighter with a one touch ignition resistance device illustrating the internal mechanical structure 5. BEST MODE FOR CARRYING OUT THE INVENTION AND
INDUSTRIAL APPLICABILITY:
Figures 1 through 3 generally illustrate the present invention, a child resistant lighter, in one of its SUBSTITUTE SHEET (RULE 26) preferred embodiments. The lighter is constructed of a tank cap (2) connected upward to a gas tank (1) and is securely fastened to the gas tank (2) by a bracket (3). The tank cap (2) includes a gas supply pipe (5) encompassed by the gas tank (1) and attached to the burner assembly (7). A nozzle (6) protudes from the burner assembly (7) and is engaged by a nozzle lever (8) to open and close the nozzle (6). A
flint (9) is located within a vacuum area of the tank cap (2) and biased upward by a flint spring (9A). A spark wheel (10) is in contact with the flint (9) and is connected to a side wheel (11). During operation, the user rotates the side wheel (11) with his thumb and simultaneously, depresses the nozzle lever (8) causing the side wheel (11) to rotate the spark wheel (10) against the flint (9) producing sparks which eventually result in ignition with the gas emitted from the nozzle (6) that opens up from the depression of the nozzle lever (8). A metal cap (4) encloses the nozzle (6) and burner assembl (7) to y protect the flame.
The new and novel improvement of the present invention includes the addition of an ignition resistance button (B).
The ignition resistance button (B) is contained within a vacuum area (2A) and is biased upward by an elastic spring (S) to traverse through the nozzle lever (8). An air way (8B) surrounds the ignition resistance button (B) at the point that the ignition resistance button (B) traverses through the nozzle lever (8) to permit the ignition resistance button (B) to move independent of the nozzle lever (8). During operation, the ignition resistance SUBSTITUTE SHEET (RULE 26) button (8) is depressed to the finger pad (8A) wherein the ignition resistance button (B) and the nozzle lever (8) are 5 depressed simultaneously to open the nozzle (6) and emitting gas to be ignited.
The lighter is difficult for a yound child to operate by increasing the requisite amount of force and manual dexterity needed to ignite the lighter. A child's thumb is not sufficiently strong to depress the ignition resistance button (B) to the finger pad (8A) and thereby prevents engagement of the nozzle lever (8). Moreover, because the nozzle lever ( 8 ) is not depressed, the nozzle ( 6 ) is not engaged and gas is not released. Additionally, the invention adds additional analytical steps to the process of understanding the operation of the lighter to further hinder the ability of small children to use the lighter.
