摘要： The present invention intends to provides a piezoelectric ignition lighter capable of avoiding misuse by children but maintaining excellent operability for normal users without unreasonably increasing actuation load at the initial ignition operation. For this end, the piezoelectric ignition lighter has a valve mechanism, a nozzle 3 and a piezoelectric mechanism 4 at the top of a lighter body 1 and ignites by actuation of an actuation cap 6 integrally molded of polyacetal resin with torsion plates 7,7. The torsion plates 7,7 are separated from the upper end surface 1a of the lighter body 1 by a gap equal to about 60%˜90% of the actuation stroke in the non-actuated condition to provide a normal (light) actuation load at the initial actuation stage. After engagement of the torsion plates 7,7 with the upper end surface of the lighter body 1, resilient load of the torsion plates is added to normal load, thereby increasing the actuation load.

摘要： A safety device in a lighting rod comprises a locking member having an engagement section, which interferes with a portion of an operation member and thereby locks the lighting operation of the operation member. The locking member can move in a direction, that intersects with the direction along which the operation member moves. An urging member urges the locking member to a locking direction. The locking member is provided with a lock releasing section, which can be operated in order to move the locking member in a direction, that acts against the urging force of the urging member. The lock releasing section is projected to a position, which stands facing the operating section of the operation member. The lock of the lighting operation is released by operating the lock releasing section of the locking member, and the lighting operation is carried out in this state by operating the operating section of the operation member. The locking member automatically returns to the state of the locking as the operation member returns to its original position.

摘要： Malfunctions caused by dusts such as sands and the like in movement portions of a spark-voltage generation mechanism are reduced. The generation mechanism comprises an outer-box assembly in which a base piece, piezoelectric element, and anvil are disposed in line with the longitudinal axis, an axis-direction cam groove is formed thereon, an inner-box assembly in which a hammer that strikes the piezoelectric element and a hammer spring are housed, a cam hole is formed thereon, and a joint-case assembly that limits the stroke of the outer-box assembly over the inner box-assembly, generates a high-voltage pulse by series of operations where one-way-pressure force is applied with a hammer pin inserted into the hammer, the cam groove, and the cam hole to compress and release the hammer spring. The hammer strikes the piezoelectric element by releasing the compression force of the hammer spring, the operation mechanism is shielded with the joint-case assembly.

摘要： A lighting rod is provided with a rod-like top end portion and a main body, the rod-like top end portion being provided with a jetting nozzle for jetting out a gas, the main body being provided with a gas tank, a valve mechanism for opening and closing a path through which the gas is supplied from the gas tank to the jetting nozzle, a piezo-electric unit for generating a discharge voltage for lighting the gas, and an operation member which drives the valve mechanism and the piezo-electric unit in order to carry out a lighting operation. A safety device for the lighting rod includes a locking member which is supported for rotation on the main body to be rotatable between a locking position where it prevents the lighting operation of the operation member and a lock release position where it permits the lighting operation of the operation member, and a spring which urges the locking means toward the locking position.

摘要： A lighting device comprises a valve mechanism for opening and closing a path, through which a gas is supplied from a gas tank to a jetting nozzle, a piezo-electric unit for generating a discharge voltage for lighting the gas, and an operation member, which can slide and drives the valve mechanism and the piezo-electric unit in order to carry out a lighting operation. A locking member capable of moving between a position for locking and a position for lock release works such that, when the locking member is set at the position for the locking, the locking member may lock the lighting operation of the operation member, and such that, when the locking member is set at the position for the lock release, the locking member may allow a single lighting operation of the operation member. A restraining member allows successive lighting operations of the operation member when the locking member is moved to the position for the lock release.

摘要： A gas lighter with a safety device is provided with a resilient leaf which can be deformed between a locked state in which the depression of a pressing means is prevented and a lock-released state in which the operation of the pressing means is allowed, and a slide member which is fitted around the resilient leaf and is movable between a first position where ignition operation is impracticable when the resilient leaf is in a locked state and a second position where the ignition operation is practicable. The slide member deforms the resilient leaf and renders it in a lock-released state at a third position which is reached during movement from the second position to the first position in response to ignition operation. The gas lighter is also provided with a deformation suppressing means for reducing the amount of deformation of the resilient leaf obtained when the slide member is located at the second position so as to be less than the amount of deformation of the resilient leaf in a lock-released state when the slide member is located at the third position.
