Abstract
A lighter safety system which in a first "safety on" position prevents the ignition of the lighter by blocking the depression of the lighter trigger. The simultaneous forward engagement of a safety pin with the operator's thumb and the rearward depression of the trigger by the operator's fingers (of the same hand) allows the lighter to ignite. The safety pin is pivotable about a positioning pillar in the housing. A hook on one end of switch engages on slanted slot in the trigger to prevent depression of the trigger until the pivotable switch pin is urged forward.

2 Title: LIGHTER WITH A SAFETY SYSTEM
The present invention relates to a lighter device, and more particularly to a unique safety 6 system incorporated into the lighter. Specifically, the present invention relates to a push button 7 safety switch which cooperates with an ignition trigger of the lighter to allow ignition of the lighter 8 by coordinating the simultaneous deactivation of the safety and the engagement of the trigger.
9 Current safety switches on lighters are awkward to engage. Some switches are such that when the switch is moved to the "safety off' position to allow the operator to ignite the lighter, by 11 pulling a trigger mechanism, the safety remains in the "safety off"
position allowing for subsequent 12 unprotected ignition attempts. This may be a dangerous condition if the lighter falls into the hands 13 of a child. Since such safety switches do not automatically re-engage to the "safety on" position, a 14 child could pull the ignition trigger and ignite the lighter.
1 S Additionally, other prior art devices include U.S. Patent Nos. 5,865,614;

Since such safety switches do not automatically re-engage to the "safety on" position, a 14 child could pull the ignition trigger and ignite the lighter.
1 S Additionally, other prior art devices include U.S. Patent Nos. 5,865,614;
5,697,775; and I 6 5,496,1 G9.
17 U.S. Patent No. 5,697,775 illustrates and teaches a safety switch which requires the operator 18 to press the safety switch downwardly while pulling the trigger rearwardly.
While the device is 19 difficult for children to use, it is an awkward operation for even adults to use. Further one embodiment of the device of U.S. Patent No. 5,697,775 houses the safety switch in the trigger 21 section of the lighter housing.
1 The present invention places the safety switch on top of the lighter housing outside and away 2 from the trigger section. The present invention allows for the simultaneous engagement of the safety 3 switch by urging the switch forward to the "safety off' position while the ignition trigger is pulled 4 rearwardly. This requires a level of coordination not normally obtained by children, but still simple S enough for adults. Thus, the operator simultaneously pulls the ignition trigger rearwardly with the 6 forefinger of one hand and urges the safety switch forward with the thumb of the same hand. The 7 lighter then lights. The safety switch may then be released and the flame continues. After the trigger 8 is released, the flame is extinguished. The safety switch automatically returns to the "safety on"
17 U.S. Patent No. 5,697,775 illustrates and teaches a safety switch which requires the operator 18 to press the safety switch downwardly while pulling the trigger rearwardly.
While the device is 19 difficult for children to use, it is an awkward operation for even adults to use. Further one embodiment of the device of U.S. Patent No. 5,697,775 houses the safety switch in the trigger 21 section of the lighter housing.
1 The present invention places the safety switch on top of the lighter housing outside and away 2 from the trigger section. The present invention allows for the simultaneous engagement of the safety 3 switch by urging the switch forward to the "safety off' position while the ignition trigger is pulled 4 rearwardly. This requires a level of coordination not normally obtained by children, but still simple S enough for adults. Thus, the operator simultaneously pulls the ignition trigger rearwardly with the 6 forefinger of one hand and urges the safety switch forward with the thumb of the same hand. The 7 lighter then lights. The safety switch may then be released and the flame continues. After the trigger 8 is released, the flame is extinguished. The safety switch automatically returns to the "safety on"
9 position preventing accidental ignition.
12 The present invention is a lighter having an ignition trigger operable within the lighter 13 housing. A safety switch operable within the same housing but away from the trigger section, 14 includes a pivotable safety pin movable from a first "safety on" position to a second "safety off' I 5 position. The pivot pin has an engagement foot on the distal end of the pin which blocks the ignition 16 trigger from being pulled or activated to initiate ignition of the lighter.
The engagement foot 17 engages a slot in the trigger. A narrow leg extends upwardly from the engagement foot and is 18 provided with a generally central opening to receive a positioning pillar which acts as the pivot 19 point. When the tap of the pin is urged forwardly along a generally longitudinal axis of the lighter while simultaneously with the pulling of the trigger oppositely along the same general longitudinal 21 axis of the lighter, the narrow leg of the safety pin pivots and the foot disengages from the trifler 22 slot. The trigger then may be pulled sufficiently to initiate lighter ignition. Thus, the simultaneous 1 forward movement of the pin from "safety on" to "safety ofP' with the rearward pulling of the trigger 2 along the same general longitudinal axis of the lighter activates the lighter. It is the arrangement and 3 movement of the elements of the present invention which results in a safety system requiring a level 4 of hand coordination not normally developed in a child and yet not so awkward as to inconvenience adults. Once the trigger is released, the pin automatically returns to the "safety on" position.

6 DETAILED DESCRIPTION OF THE PREFERRFn FMRnnmrFNT
7 Figs. 1 A, 1 B and 1 C illustrate a typical prior art lighter 10 having an ignition trigger 16 8 operable within the lighter housing 18. The operation of such lighters is well-known in the art. The 9 operator holds the lighter 10 by one hand and pulls or presses the trigger 16 with his or her finger.
Movement of trigger 16 pushes the gas lever 19 downwardly which in turn elevates nozzle A to 11 release gas. Gas is driven to upper end nozzle B through gas pipe 23. At the time the trigger 16 is 12 depressed, piezoelectric actuator 21 is vibrated to emit an electric charge which is transmitted to 13 conductive pipe 25 through its conducting wire.
14 Since pipe 25 is a conductor, an electric charge is conducted to pipe end 25A.
Simultaneously, another electric circuit transmits the electric charge to nozzle B through the contact 16 of the bottom of piezoelectric actuator 21 A and ground wire 22. Because nozzle B is a conductor, 17 electric charge is conducted to sparkling spring 31. When meeting a spark, the gas lights a flame 18 100.
19 The present invention is shown in detail in Figs. 2A, 2B and 2C. The safety system 102 is built into the lighter 11 without any significant modifications to the existing prior art lighter 10. The safety s~:~t~h is o"tside the trigger section and requires a forward pressure on the switch head or top 22 and a rearward depression of the trigger to activate the lighter 11.
I The lighter housing 18 is designed to include an opening 18B on the top side of the lighter 2 11 for pivotal switch safety pin 37 whereas trigger 16 on the underside of the lighter in the trigger 3 section is designed with a slanted slot 16B and a top edge 16A (Fig. 3).
Additionally, a torsional 4 switch spring 38 is designed for inclusion in the present invention to urge the safety pin 37 to the "safety on" position.
6 In Figs. 3-6, most of the lighter parts are not shown so that the safety system 102 of the 7 present invention may be more clearly observed. As may be seen in Figs. 3-6, switch safety pin 37, 8 switch spring 38, and trigger 16 are assembled in housing 18. Pivotal switch safety pin 37 is urged 9 rearward to the "safety on" position under the spring action of spring 38.
Top end 38A of the spring comes in contact with inner bottom part 18E of housing 18 and lower spring end 38B applies 11 torsional farce against the front side 37D of narrow leg 37E of pin 37.
12 In this first position trigger top edge 16A and slanted slot 16B come in contact with hook 37F
13 of engagement foot 37A. It is, therefore, not possible to press the trigger 16 rearwardly to ignite the 14 lighter 11 because edge 16A of trigger 16 is blocked from rearward movement by engagement foot 37A. The sharp hook 37F engages into the slanted slot 16B to further secure the trigger from 16 movement. Piezoelectric actuator 21 cannot be actuated nor can the gas lever 19 be raised to release 17 gas. The lighter cannot be ignited under this first "safety on" position.
18 The top 37B of the pin 37 pivots forward as pin 37 rotates about the positioning pillar 18A
19 which extends through a generally, central pivot opening 37C in pin 37. As may be seen in Fig. 3 the pillar 18 is generally cylindrical upstanding protrusion attached to a side wall of the housing 18.
21 The pillar is aligned i_n h~nsing opening 18B. Opening 18B has a front edge 1 RD and a rear edge 22 18C. As the pin 37 is urged forward its rotational movement is stopped by edge 18B. As will be 1 seen below when the pin 37 is released, it springs back to its first position (Fig. 4) by the action of 2 spring 38. Pin 37 is stopped in its return rotation by edge 18D.
3 Fig. 4A shows in detail the position of spring ends 38A and 38B withing the housing 18. The 4 top end 38A and 38B extend the inner side 18E of housing 18 and lower end 38B urges against the side 37D of pin 37. The spring is held securely in place by wrapping around pillar 18A as the pillar 6 body passes through the inner coil of the spring.
7 As shown in Fig. S, a top 37B on the proximal end of pivotal pin 37 must be pressed forward 8 parallel the longitudinal axis of the lighter 11 by the operator's thumb at the same time the fingers 9 of the same hand rearwardly depress the trigger 16 parallel the longitudinal axis L . Foot 37A and I0 hook 37F move rearward to disengage top edge 16A and slanted slot 16B of trigger 16. A narrow 1 I leg portion 37E of pin 37 pivots rearward bout positioning pillar 18 in housing 18. However, the 12 spring action of spring 18 seeks to urge the pivot pin 37 back to the "safety on" position. The 13 pivoting of the leg 37E, and foot 37A, and hook 37F, out of engagement with edge 16A and slanted 14 slot 16B allows the trigger 16 to be depressed and the lighter 1 I to ignite. This is a second position.
I 5 This simultaneous operation of the safety pin 37 and trigger 16 requires more hand coordination than 16 is normally achieved by a child.
17 As shown in Fig. 6, when top 37B is released, leg 37E cannot pivot back while the trigger 18 16 is rearwardly depressed. Foot 37A cannot engage slanted slot 16B. As trigger 16 is urged l 9 rearward by the forefinger, simultaneously gas lever 19 is raised by the rearward motion of trigger 20 16 to release gas. Also, the engaging of trigger 16 activates the piezo effect of piezoelectric actuator 21 21 to discharge electric charge. The gas, as released, will meet with the spark produced to light a 22 flame. This is the ignition condition in operation. Release of the forefinger after use will allow the 1 trigger to return to offposition, and pin 37 will automatically pivot back into the "safety on" position 2 as shown in Fig. 4 and 4A.
3 Although the invention has been described with reference to a specific embodiment, this 4 description is not meant to be construed in a limiting sense. On the contrary, various modifications S of the disclosed embodiments will become apparent to those skilled in the art upon reference to the 6 description of the invention. It is therefore contemplated that the appended claims will cover such 7 modifications, alternatives, and equivalents that fall within the true spirit and scope of the invention.

A safety switch operable within the same housing but away from the trigger section, 14 includes a pivotable safety pin movable from a first "safety on" position to a second "safety off' I 5 position. The pivot pin has an engagement foot on the distal end of the pin which blocks the ignition 16 trigger from being pulled or activated to initiate ignition of the lighter.
The engagement foot 17 engages a slot in the trigger. A narrow leg extends upwardly from the engagement foot and is 18 provided with a generally central opening to receive a positioning pillar which acts as the pivot 19 point. When the tap of the pin is urged forwardly along a generally longitudinal axis of the lighter while simultaneously with the pulling of the trigger oppositely along the same general longitudinal 21 axis of the lighter, the narrow leg of the safety pin pivots and the foot disengages from the trifler 22 slot. The trigger then may be pulled sufficiently to initiate lighter ignition. Thus, the simultaneous 1 forward movement of the pin from "safety on" to "safety ofP' with the rearward pulling of the trigger 2 along the same general longitudinal axis of the lighter activates the lighter.

7 Figs. 1 A, 1 B and 1 C illustrate a typical prior art lighter 10 having an ignition trigger 16 8 operable within the lighter housing 18. The operation of such lighters is well-known in the art. The 9 operator holds the lighter 10 by one hand and pulls or presses the trigger 16 with his or her finger.
Movement of trigger 16 pushes the gas lever 19 downwardly which in turn elevates nozzle A to 11 release gas. Gas is driven to upper end nozzle B through gas pipe 23. At the time the trigger 16 is 12 depressed, piezoelectric actuator 21 is vibrated to emit an electric charge which is transmitted to 13 conductive pipe 25 through its conducting wire.
14 Since pipe 25 is a conductor, an electric charge is conducted to pipe end 25A.
Simultaneously, another electric circuit transmits the electric charge to nozzle B through the contact 16 of the bottom of piezoelectric actuator 21 A and ground wire 22. Because nozzle B is a conductor, 17 electric charge is conducted to sparkling spring 31. When meeting a spark, the gas lights a flame 18 100.
19 The present invention is shown in detail in Figs. 2A, 2B and 2C. The safety system 102 is built into the lighter 11 without any significant modifications to the existing prior art lighter 10. The safety s~:~t~h is o"tside the trigger section and requires a forward pressure on the switch head or top 22 and a rearward depression of the trigger to activate the lighter 11.
I The lighter housing 18 is designed to include an opening 18B on the top side of the lighter 2 11 for pivotal switch safety pin 37 whereas trigger 16 on the underside of the lighter in the trigger 3 section is designed with a slanted slot 16B and a top edge 16A (Fig. 3).
Additionally, a torsional 4 switch spring 38 is designed for inclusion in the present invention to urge the safety pin 37 to the "safety on" position.
6 In Figs. 3-6, most of the lighter parts are not shown so that the safety system 102 of the 7 present invention may be more clearly observed. As may be seen in Figs. 3-6, switch safety pin 37, 8 switch spring 38, and trigger 16 are assembled in housing 18. Pivotal switch safety pin 37 is urged 9 rearward to the "safety on" position under the spring action of spring 38.
Top end 38A of the spring comes in contact with inner bottom part 18E of housing 18 and lower spring end 38B applies 11 torsional farce against the front side 37D of narrow leg 37E of pin 37.
12 In this first position trigger top edge 16A and slanted slot 16B come in contact with hook 37F
13 of engagement foot 37A. It is, therefore, not possible to press the trigger 16 rearwardly to ignite the 14 lighter 11 because edge 16A of trigger 16 is blocked from rearward movement by engagement foot 37A. The sharp hook 37F engages into the slanted slot 16B to further secure the trigger from 16 movement. Piezoelectric actuator 21 cannot be actuated nor can the gas lever 19 be raised to release 17 gas. The lighter cannot be ignited under this first "safety on" position.
18 The top 37B of the pin 37 pivots forward as pin 37 rotates about the positioning pillar 18A
19 which extends through a generally, central pivot opening 37C in pin 37. As may be seen in Fig. 3 the pillar 18 is generally cylindrical upstanding protrusion attached to a side wall of the housing 18.
21 The pillar is aligned i_n h~nsing opening 18B. Opening 18B has a front edge 1 RD and a rear edge 22 18C. As the pin 37 is urged forward its rotational movement is stopped by edge 18B. As will be 1 seen below when the pin 37 is released, it springs back to its first position (Fig. 4) by the action of 2 spring 38. Pin 37 is stopped in its return rotation by edge 18D.
3 Fig. 4A shows in detail the position of spring ends 38A and 38B withing the housing 18. The 4 top end 38A and 38B extend the inner side 18E of housing 18 and lower end 38B urges against the side 37D of pin 37. The spring is held securely in place by wrapping around pillar 18A as the pillar 6 body passes through the inner coil of the spring.
7 As shown in Fig. S, a top 37B on the proximal end of pivotal pin 37 must be pressed forward 8 parallel the longitudinal axis of the lighter 11 by the operator's thumb at the same time the fingers 9 of the same hand rearwardly depress the trigger 16 parallel the longitudinal axis L . Foot 37A and I0 hook 37F move rearward to disengage top edge 16A and slanted slot 16B of trigger 16. A narrow 1 I leg portion 37E of pin 37 pivots rearward bout positioning pillar 18 in housing 18. However, the 12 spring action of spring 18 seeks to urge the pivot pin 37 back to the "safety on" position. The 13 pivoting of the leg 37E, and foot 37A, and hook 37F, out of engagement with edge 16A and slanted 14 slot 16B allows the trigger 16 to be depressed and the lighter 1 I to ignite. This is a second position.
I 5 This simultaneous operation of the safety pin 37 and trigger 16 requires more hand coordination than 16 is normally achieved by a child.
17 As shown in Fig. 6, when top 37B is released, leg 37E cannot pivot back while the trigger 18 16 is rearwardly depressed. Foot 37A cannot engage slanted slot 16B. As trigger 16 is urged l 9 rearward by the forefinger, simultaneously gas lever 19 is raised by the rearward motion of trigger 20 16 to release gas. Also, the engaging of trigger 16 activates the piezo effect of piezoelectric actuator 21 21 to discharge electric charge. The gas, as released, will meet with the spark produced to light a 22 flame. This is the ignition condition in operation. Release of the forefinger after use will allow the 1 trigger to return to offposition, and pin 37 will automatically pivot back into the "safety on" position 2 as shown in Fig. 4 and 4A.
3 Although the invention has been described with reference to a specific embodiment, this 4 description is not meant to be construed in a limiting sense. On the contrary, various modifications S of the disclosed embodiments will become apparent to those skilled in the art upon reference to the 6 description of the invention. It is therefore contemplated that the appended claims will cover such 7 modifications, alternatives, and equivalents that fall within the true spirit and scope of the invention.
