    • The present invention relates to a utility lighter including a housing having a handle at one end and a nozzle with an outlet at another end and including a fuel supply connected for selective fluid communication with the nozzle. An electric ignitor assembly, such as a piezoelectric mechanism, has first and second electrical contacts operatively connected to a first electrical pathway. The first electrical pathway includes a first gap proximate the outlet. An ignition preventing assembly forming a second electrical pathway is also operatively connected to the electric ignitor assembly and has operative and inoperative configurations. In the inoperative configuration, the resistance of the second electrical pathway is less than the resistance of the first electrical pathway such that electrical current generated by the electric ignitor assembly selectively travels in the second electrical pathway. In the operative configuration, the resistance of the second electrical pathway is greater than the resistance of the first electrical pathway such that the electrical current selectively travels in the first electrical pathway and jumps across the first gap to form a spark to ignite fuel from the fuel supply. The second electrical pathway can be a continuous pathway to short circuit the electrical ignitor assembly in the inoperative condition. The second electrical pathway can also include a gap smaller than the first gap so that the spark is formed across this gap rather than the first gap in the inoperative condition. The ignition preventing assembly can be coupled with various mechanical mechanisms for preventing unwanted actuation.
    • 本发明涉及一种实用打火机,其包括一端具有手柄的壳体和在另一端具有出口的喷嘴,并包括连接用于与喷嘴选择性流体连通的燃料供应。 诸如压电机构的电触发器组件具有可操作地连接到第一电路径的第一和第二电触点。 第一电路包括靠近出口的第一间隙。 形成第二电气路径的点火防止组件也可操作地连接到电触发器组件,并且具有操作和不可操作的配置。 在不工作的配置中,第二电路的电阻小于第一电路的电阻,使得由电点火器组件产生的电流在第二电路中选择性地行进。 在操作构型中,第二电路的电阻大于第一电路的电阻,使得电流在第一电路中选择性地行进并跳过第一间隙以形成火花以从燃料点燃燃料 供应。 第二电路可以是使电触发器组件在不工作状态下短路的连续路径。 第二电路还可以包括小于第一间隙的间隙,使得在该间隙上形成火花,而不是在不工作状态下形成第一间隙。 点火防止组件可与各种机械机构结合,以防止不必要的致动。

    • A selectively actuatable lighter device is disclosed which includes a body defining reservoir for containing a combustible gaseous medium such as butane, and having a valve arranged to be selectively actuated between a normally closed position and an open position which permits the exit of the gaseous medium. Such lighter can selectively produce sparks at a location proximate to the gaseous medium exit to ignite the gaseous medium. Such lighter device embodies a resiliently releasable latch which normally prevents actuation of a valve actuator to the open position thereby preventing actuation of the valve. The latch is selectively movable to a position out of interference with the valve actuator, so that the gaseous medium may be released and ignited by the sparks. The latch is resiliently structured and mounted such that once a flame is produced and the valve actuator is released, the latch returns to its closed or latched position to prevent actuation of the valve to the open position by prevention of the pivotal motion of the valve actuator. To "re-use" the lighter, the latch must again be moved to an unlatched position so that the valve actuator can be opened for subsequent ignition of the gaseous medium.

    • An improved selectively actuatable child resistant lighter device is disclosed which includes a body defining reservoir for containing a combustible gaseous medium such as butane, and having a valve arranged to be selectively actuated between a normally closed position and an open position which permits the exit of the gaseous medium. A locking mechanism normally prevents actuation of the valve to the open position. Such child resistant lighter device embodies a resiliently releasable locking latch which prevents movement of a fuel nozzle from a first, or fuel cutoff, position to a second, or fuel flow, position. The locking latch is selectively movable to an unlocked position in which depression of a valve actuator causes the fuel nozzle to move from the fuel cutoff position to the fuel flow position, so that the gaseous medium may be released and ignited by the sparks. The locking latch is resiliently structured and mounted such that once a flame is produced and the valve actuator is released, the locking latch returns to its closed or locked position to prevent actuation of the valve to the open position. To "re-use" the lighter, the locking latch must again be moved to the unlocked position so that the fuel nozzle may expel fuel upon depression of the valve actuator. Such mechanism is difficult for a young child to light, but is capable of actuation by adults.
