Abstract:
A cigarette lighter comprising:a tank for a combustible gas under pressure;a valve which is normally closed to prevent gas from exiting the tank, but which can be opened to allow gas to escape from the tank through a nozzle;a valve actuator operable to open the valve;a spark producer operable to produce a spark in the vicinity of the nozzle and cause ignition of gas escaping from the tank when the valve is opened by the valve actuator;a spark producer holder having an upstanding extension with an end;a push button operable by engagement of a user's finger to operate the valve actuator, open the value and operate said spark producer, anda movable safety device in the form of an elongated resilient bar provided at one end with a rotatable operating member and at the other end with an extension, said safety device being movable between a normal position in which the safety device prevents operation of the push button by means of the extension engaging the end of the upstanding extension of the spark producer holder, and an operating position to which the safety device can be moved by rotation of the operating member about an axis which is substantially parallel to the length of the safety device, whereby the extension of the safety device is moved out of engagement with the end of the upstanding extension of the spark producer holder simultaneously as the push button is pushed inwards so that the extension moves down the side of the upstanding extension, returning to its normal position after use of the cigarette lighter.
