Cigarette lighter

A cigarette lighter comprising:

• (a) a tank for a combustible fluid;
• (b) a normally closed feed valve connected to the tank for preventing exit of the combustible fluid from the tank, the feed valve being openable in response to external force for feeding the fluid for combustion thereof;
• (c) a base fixedly supported relative to the valve;
• (d) a valve actuator movably supported relative to the base for opening the valve, the actuator transmitting the external force when opening the valve;
• (e) ignition means for igniting fluid being fed from the tank when the valve is engaged and opened by the valve actuator;
• (f) a safety device movably supported relative to the base and operable from a normal position for holding the valve actuator disengaged from the valve to a released position for enabling the valve actuator to engage and open the valve, the safety device comprising:
• (i) a body member rotatably supported relative to the base between first and second angular positions and having an eccentrically formed engagement portion for laterally shifting the actuator for movement thereof between a first path relative to the base in response to the external force in the released position of the safety device for actuating the valve, and a second path in the normal position of the safety device, at least a portion of the second path being laterally shifted relative to the first path, whereby the body member is in the first angular position in the normal position of the safety device and the second angular position in the released position, movement of the actuator in response to the external force not producing contact with the valve;
• and
• (ii) a radially projecting safety handle for moving the body member to the second angular position;
• the actuator being movable in a first path relative to the base in response to the external force in the released position of the safety device for actuating the valve and in a second path in the normal position of the safety device, at least a portion of the second path being laterally shifted relative to the first path whereby movement of the actuator in response to the external force does not produce contact with the valve;
• (g) biasing means for automatically returning the safety device to the normal position whereby the valve actuator is prevented from engaging the valve after use of the cigarette lighter, the biasing means being connected between the base and the body member for rotatably urging the body member to the first angular position, the body member being axially movable relative to the base in the second angular position from a normal position to a cocked position for preventing movement thereof by the biasing means to the first angular position;
• and
• (h) a trigger for automatically returning the body member to the normal position from the cocked position upon activation of the valve by the actuator.

A cigarette lighter comprising:

• (a) a tank for a pressurized combustible gas;
• (b) a normally closed feed valve having a nozzle outlet, the valve being connected to the tank for preventing exit of the gas from the tank, the feed valve being openable in response to external force for feeding the gas for combustion thereof;
• (c) a base fixedly supported relative to the valve;
• (d) a valve actuator movably supported relative to the base for opening the valve, the actuator transmitting the external force when opening the valve;
• (e) ignition means for igniting gas being fed from the tank when the valve is engaged and opened by the valve actuator, the ignition means producing a spark in the vicinity of the nozzle;
• (f) a safety device movably supported relative to the base and operable from a normal position for holding the valve actuator disengaged from the valve to a released position for enabling the valve actuator to engage and open the valve, the safety device comprising:
• (i) a body member rotatably supported relative to the base between first and second angular positions and having an eccentrically formed engagement portion for laterally shifting the actuator for movement thereof between a first path relative to the base in response to the external force in the released position of the safety device for actuating the valve, and a second path in the normal position of the safety device, at least a portion of the second path being laterally shifted relative to the first path, whereby the body member is in the first angular position in the normal position of the safety device and the second angular position in the released position, movement of the actuator in response to the external force not producing contact with the valve;
• and
• (ii) a radially projecting safety handle for moving the body member to the second angular position;
• (g) biasing means for automatically returning the safety device to the normal position whereby the valve actuator is prevented from engaging the valve after use of the cigarette lighter, the biasing means being connected between the base and the body member for rotatably urging the body member to the first angular position, the body member being axially movable relative to the base in the second angular position from a normal position to a cocked position for preventing movement thereof by the biasing means to the first angular position;
• and
• (h) a trigger for automatically returning the body member to the normal position from the cocked position upon activation of the valve by the actuator, the engagement portion of the body member projecting into a cavity of the actuator, the trigger comprising an axial extremity of the engagement portion, the axial extremity being contacted by an end portion of the cavity in response to the external force during activation of the valve for axial movement of the body member.
