In the first mode, a plunger member is positioned to allow a biasing member to oppose movement of an actuating assembly so that a user releases fuel and ignites the lighter only if a high-actuation-force is applied to the actuator. In this first mode, the lighter resists operation by unintended users by requiring a user to have a predetermined level of strength to actuate the lighter. In the second mode, the plunger member is moved to a different position so that the biasing member does not oppose movement of the actuating assembly to the same extent as the first mode so that a user may release fuel and ignite the lighter if a low-actuation-force is applied to the actuator. Moving the plunger member from the first position to the second position preferably requires the user to have a predetermined level of cognitive abilities and/or physical characteristics in order to resist use by unintended users. ## Claims ### Claim 1 A lighter comprising: a housing having a supply of fuel; an igniting assembly for igniting released fuel; an actuating assembly that includes an actuating member pivotably connected to the housing for performing at least one step in igniting the fuel; a plunger member operatively associated with the latch member; at least two biasing members, a first biasing member always operatively associated with the actuating assembly and a second biasing member selectively operatively associated with the plunger member; and a latch member moveable by a user between a first latch member position and a second latch member position, wherein the user applies a first actuating force to the actuating member to ignite the fuel when the latch member is positioned in the first latch member position, and a second actuating force to the actuating member to ignite the fuel when the latch member is positioned in the second latch member position, the first actuating force being greater than the second actuating force. ### Claim 2 (depends on 1) The lighter according to claim 1, wherein a predetermined actuating force is necessary to move the actuating member to an actuation position to actuate the lighter, when the latch member is in the first latch member position and the first actuating force is greater than the predetermined actuating force. ### Claim 3 (depends on 1) The lighter according to claim 1, wherein the latch member moves in a linear direction when the user applies a force thereto. ### Claim 4 (depends on 1) The lighter according to claim 1, wherein the actuating member is an activation mechanism having a surface exterior to the lighter housing which is pivotably coupled to the housing. ### Claim 5 (depends on 1) The lighter according to claim 1, wherein in the first latch position a surface of the latch member protrudes from beyond the housing, and in the second latch position the surface of the latch member is located within the housing. ### Claim 6 (depends on 1) The lighter according to claim 1, wherein when the latch member is in the first latch member position and the first actuating force is applied to the actuating member, the plunger member compresses the first biasing member and the actuating assembly compresses the second biasing member and the lighter is actuated. ### Claim 7 (depends on 1) The lighter according to claim 1, wherein when the latch member is in the second latch member position and the second actuating force is applied to the actuating member, the actuating assembly compresses the first biasing member, the plunger member does not compress the second biasing member when the actuating assembly is pivoted within the housing. ### Claim 8 (depends on 1) The lighter according to claim 1, wherein actuating the lighter is accomplished by movement of the latch member and the actuating assembly. ### Claim 9 (depends on 1) The lighter according to claim 1, wherein the igniting assembly comprises a piezoelectric unit. ### Claim 10 (depends on 1) The lighter according to claim 1, wherein the actuating member selectively dispenses the fuel and activates the igniting assembly. ### Claim 11 (depends on 1) The lighter according to claim 1, wherein the actuating assembly further includes an activation mechanism tub, an actuating tab, and a gas opening tab. ### Claim 12 (depends on 11) The lighter according to claim 11, wherein the plunger member is carried by and slidably associated with activation mechanism tab. ### Claim 13 (depends on 1) The lighter according to claim 1, wherein actuation of the lighter when the latch member is in the first latch member position requires a single finger of a user. ### Claim 14 (depends on 1) The lighter according to claim 1, wherein actuation of the lighter when the latch member is in the second latch member position may entail use of a first and second finger, preferably of the same hand, of the user. ### Claim 15 (depends on 1) The lighter according to claim 1, wherein the lighter is configured and adapted to operate by moving the latch member before moving the actuating member. ### Claim 16 (depends on 1) The lighter according to claim 1, wherein the lighter is configured and adapted to operate by relying on the physical characteristics of a user when the latch member is in the first latch member position. ### Claim 17 (depends on 1) The lighter according to claim 1, wherein the lighter has a wand that extends from the housing of the lighter that contains a nozzle to release the fuel, and wherein the wand is at least 2 inches long. ### Claim 18 A lighter comprising: a housing having a supply of fuel; an actuating assembly for selectively releasing the fuel, wherein the actuating assembly includes an actuating member pivotably connected to the housing; an ignition assembly for igniting the released fuel; a latch member movable in a linear direction to permit movement between a first latch position and a second latch position; a plunger member operatively associated with the latch member; a first biasing member operatively associated with the actuating assembly; and a second biasing member operatively associated with the plunger member, wherein at least a portion of the plunger member is repositioned by the latch member from a first member position which causes the first biasing member and second biasing member to resist movement of the actuating member to a second member position so that the second biasing member does not resist movement of the actuating member, and wherein the actuating member is movable to ignite the released fuel when the plunger member is in the first member position and when the plunger member is in the second member position.
