Abstract
A safety lighter with improved rotary wheel hoods surrounding the striker wheel. The hoods must be urged downwardly and simultaneously rotated to engage and rotate the striker wheel. By varying the arrangement of the annular inner and outer surfaces of the hoods having either smooth surfaces or protuberances thereon with the annular unrecessed lateral portions of the striker wheel having either smooth surfaces or protuberances thereon, a multiplicity of embodiments may be achieved. Each embodiment requires a varying level of downward pressure and rotational forces to cause the lighter to spark and ignite.
Description




BACKGROUND OF THE INVENTION




The present invention relates to the field of lighters, such as cigarette lighters. More particularly the invention relates to safety lighters having rotary striker wheels. U.S. Pat. No. 5,769,625, which is incorporated herein by reference for all purposes, discloses a state of the art safety lighter with an improved striker wheel and striker wheel mounting frame. The lighter has an igniter having a striker wheel which rotates about an axis in response to force applied to the wheel by a user's finger. The annular recessed center portion of the striker wheel's outer annular surface has protuberances formed thereon (or grooves formed therein), while the annular unrecessed lateral portions of the striker wheel's outer annular surface are smooth. Further, the striker wheel is mounted to the lighter in slots. The striker wheel is pressed from a first position having insufficient spring force to cause the lighter flint to spark when the striker wheel is rotated into a second position having sufficient spring force to cause the lighter flint to spark when the striker wheel is rotated.




While the depression of the striker wheel from a first position to a second position is an effective safety mechanism, the present invention provides an improvement whereby the rotoring striker wheel remains in the same position and rotates about the same horizontal axis. There is no up or down displacement of the striker wheel. Rather, the present invention utilizes rotary hoods which are displaced from a first position to a second position to engage the outer edges of the striker wheel to translate rotary motion to the wheel and ignite the lighter.




SUMMARY OF THE INVENTION




The present invention is a lighter comprising an igniter having a striker wheel which rotates about an axis in response to force applied to the wheel by a user's thumb (or any other finger or hand part). The striker wheel has an outer annular surface having an annular recessed center portion and annular unrecessed lateral portions.




The annular recessed portion has a rough surface with protuberances formed thereon (or grooves formed therein). The annular unrecessed lateral portions of the striker wheels may be smooth or have protuberances thereon, depending upon the embodiment.




Rotary wheel hoods circumferentially surround the annular unrecessed lateral portions of the striker wheel. The hoods have inner and outer annular surfaces. The hoods also have a central opening formed therethrough to rotatably receive the central axle of the striker wheel. The central opening has a diameter greater than the diameter of the central axle. Thus, the rotary wheel hoods are movable from a first position where the inner surface of the hoods do not contact the striker wheel to a second position where the inner surface of the hoods engage the striker wheel along the annular unrecessed lateral portions and impart rotational movement to the striker wheel to create sparks. The sparks ignite the lighter when the igniter is activated. The inner and outer surfaces of the hoods may be smooth or have protuberances thereon, again, depending upon the embodiment of the invention.

DETAILED DESCRIPTION OF THE INVENTION




The preferred embodiment of the invention is illustrated in the attached drawings which are referred to herein. The same reference numeral will be used to identify identical elements throughout the drawings.





FIGS. 1A-1C

illustrate components commonly mounted on a lighter body


601


in which lighter fuel is contained. Such components include nozzle


608


having a head and a downwardly extending tube disposed toward the front of the lighter body


601


, flame adjustment wheel


607


and thumb adjustment actuator


615


which is connected to the flame adjustment wheel, mounting frame


614


, windshield


621


, nozzle actuating lever


616


, and an igniter comprising flint spring


617


, flint


618


, and striker wheel


620


.




The tube of the nozzle is connected in communication relationship with the interior of the lighter body where, as mentioned above, fuel is stored. The nozzle may be moved from a lower position to an upper position. When the nozzle is in its lower position, fuel cannot be ejected from it. When the nozzle is in the upper position, fuel is ejected from it. In normal operation, a lighter's striker wheel is rotated and the rear of lever


616


is depressed virtually simultaneously, which causes the nozzle to be raised and a spark to be created when the teeth of the striker wheel fictionally engage the flint


618


. The spark ignites the fuel and a flame is maintained so long as the rear of the lever is continued to be depressed downward.




Frame


614


is mounted on the lighter body with hollow frame stem


614


D inserted in hole


601


A of the lighter body. Nozzle actuating lever


616


is mounted on the frame with pivots


616


A inserted into slots


614


B. Striker wheel


620


is formed in the shape of a wheel having an annular center portion


619


of its outer annular surface recessed relative to the annular lateral portions


620


A of the striker wheel's outer annular surface. The striker wheel is mounted on frame


614


with the wheel's axle


620


B fitting into holes


614


C. Flint


618


and flint spring


617


are mounted in hole


614


A of the mounting frame in the conventional fashion so as to urge the flint


618


toward protuberances


619


A which are disposed on the annular recessed surface


619


of the striker wheel.




The protuberances


619


A on annular recessed center portion


619


are a series of saw-tooth-shaped teeth, each having a first surface which is substantially perpendicular to the tangent of the circle from which the protuberances extend. This first surface faces in the clockwise direction as the lighter is viewed from the side shown in

FIG. 4A



a


. Each tooth also has a second surface, which slopes toward the counter-clockwise direction of the wheel when the lighter is viewed from its side with the front (or nozzle) end of the lighter toward the left as shown in

FIG. 4A



a.







FIGS. 1A-1C

illustrate that same general arrangement may be utilized in each embodiment of the invention. The principal difference with each embodiment relates to the rotary wheel hoods


922


and the annular unrecessed lateral portions


620


A of striker wheel


620


.




Turning now to the inventive rotary wheel hoods


922


, it may be seen that the hoods are cap-like shrouds which circumferentially surround the annular unrecessed lateral portions


620


A of the striker wheel


620


. The hoods have inner


922


D and outer


922


C annular surfaces. Each hood has a central axle opening


922


A formed therethrough to rotatably receive the central axle


620


B of the striker wheel. The diameter of the axle opening


922


A is greater than the diameter of the axle


620


B. Further, the inner diameter d


i


of the rotary wheel hood


922


is greater than the diameter d


w


of the annular unrecessed lateral portions


620


A of the striker wheel


620


. Thus, the striker wheel


620


cannot be actuated or rotated even if the rotary wheel hoods


922


are rotated. Only by pressing or urging downwardly upon the outer annular surface


922


C of the hoods


922


while simultaneously rotating the hoods may the striker wheel


620


be rotated about its axle


620


B.




As may be seen in the various figures, the inner annular surface


922


D may be smooth or may have protuberances thereon. In the same way the outer annular surface


922


C may be smooth or may have protuberances thereon. Likewise, the annular unrecessed lateral portions


620


A of the striker wheel


620


may have protuberances (arrangement b,

FIG. 1A

) or be smooth (arrangement a, FIG.


1


A).





FIG. 1A

illustrates both inner and outer annular surfaces of the hoods


922


as being smooth, but the annular unrecessed lateral portion


620


A of the striker wheel


620


may be smooth (b) or have protuberances (a). The amount of pressure which must be applied to the hoods


922


to cause rotation of the striker wheel


620


will vary depending upon the arrangement of the smoother versus protuberanced surfaces of the hoods and the smooth versus protuberanced surfaces of the annular unrecessed lateral portions


620


A of the striker wheel


620


.





FIG. 1B

illustrates hoods


922


having smooth inner surfaces


922


D and outer surfaces


922


C having protuberances. Again, the striker wheel is shown having protuberances in arrangement (a) while in arrangement (b) these unrecessed lateral portions


620


A are smooth. Flint


618


and spring


617


are assembled into hole


614


A of the mounting frame. Under action of spring


617


, the upper end of the flint


618


is urged against the under side of the recessed portion


619


of the striker wheel


620


. In this first position, if a child rotates outer surface


922


C of the hood


922


in the clockwise direction, only the hood


922


will rotate while the striker wheel


620


will not rotate because the diameter of the axle opening


922


A of the hood


922


is larger than that of the axle


620


A and the inner diameter d


i


of the hood


922


is greater than the diameter d


w


of the annular unrecessed lateral portions


620


A.





FIG. 1C

shows hoods


922


having protuberances on the annular inner surfaces


922


D and annular outer surfaces


922


C being smooth. Arrangement (a) of the striker wheel


620


shows lateral portions with protuberances and arrangement (b) shows lateral portions being smooth. Operation in the first position of the hoods, with no downwardly urging pressure, is the same as in

FIGS. 1A and 1B

.





FIGS. 2A-2C

illustrate detailed views of the upper portion of the lighters of

FIGS. 1A-1C

, respectively, and more clearly show the inventive aspects of the hoods


922


. Operation has been discussed previously.

To ignite a flame, it is necessary to press downwardly upon the annular outer surfaces

922


while simultaneously rotating the hoods in a clockwise direction. As a result of the downward force vector upon the hoods, the annular inner surfaces

to release gas to ignite a flame. Release of pressure on the hoods allows them to rebound to the first safety position away from the unrecessed lateral portions of the striker wheel as shown in FIGS.
