Further, by rotating the ignition operator, sparks are generated and gas ignition is performed.

Conventionally, the file wheel and ignition operator of such a gas lighter have been interlocked together via a long rod-shaped support shaft and rotatably supported on the lighter body.

For example, as shown in FIG.
Vertical groove-shaped opening 1a provided on the upper end side surface of the
Then, a cylindrical ignition operator 3 with a through hole provided at the center in the longitudinal direction is inserted from the outside, and then a long rod-shaped support shaft 4c is inserted into the through hole of the ignition operator 3. The rod-shaped support shaft 4c and the ignition operator 3 were integrally screwed together at a predetermined position by being inserted from the bottom, and a rotatably arranged file wheel 4 was protruded from the upper end of the ignition operator 3. The rod-shaped support shaft 4
c, and the lower end of the rod-shaped support shaft 4c is pivotally supported on the lighter body 1 via a locking body 4d, and by rotating the ignition operator 3, the rod-shaped support shaft 4c are linked together, and the file wheel 4 at the tip rotates together.

Further, a gas tank having a tinder assembly including a gear and a tinder pipe is fitted into a lighter whose top lid is pivotally connected by a hinge, and a fire extinguishing lever having one end engaged with the tinder pipe is pivoted onto the gas tank. At the same time, a pedestal is attached, and a flint storage cylinder (stone holding member) having a flint holding hole and a spare flint holding hole is fitted into the pedestal so as to be movable up and down via a spring. is a rock whose other end is pivotally supported by the pedestal, and a plunger which partially engages with the fire extinguishing lever is installed in the upper lid, and which can enter into the flint holding hole by a spring on the top of the pedestal. A pushing member is fitted so as to be horizontally movable, and furthermore, it is installed in a corner of the case so as to be operable from the outside, and its upper end is supported by the mount and its lower end is supported by a base plate integrated with the fuel tank. An ignition operator (operating wheel) is provided, and a gas ejection amount adjustment wheel including a gear is provided coaxially with the ignition operator at the bottom of the ignition operator, and the gear and the gear in the case are connected intermediately. There was a gas lighter that was connected through gears (see Publication No. 31423 of 1983).

On the other hand, as a means for interlocking the file wheel and the ignition operator, a columnar projection for a support shaft is integrally provided at the center of the upper end surface of the file wheel, a columnar projection for fixation is provided at the center of the lower end surface, and a plurality of chamfers are formed on the peripheral surface. There was an ignition file for lighters that fitted the prismatic fixing columnar protrusion with the

The ignition operator 3 has the fixing columnar projection 4b described above.
The file wheel 4 and the ignition operator 3 are interlocked by being inserted and fixed into a through hole 3a opened at the upper end of the file wheel 4. The fixing columnar projection 4b has a prismatic shape with a plurality of chamfers on the circumferential surface, and by drilling the through hole 3a of the ignition operator 3 in the same cross-sectional shape, both When fitted together, even though they can be freely attached and detached in the concentric direction, they are engaged with each other in the rotational direction and are interlocked together without rotating idly.

On the other hand, the lighter body 1 includes a gas tank 5 filled with liquefied gas, a tank cap 6 fitted into the upper opening of the gas tank 5, and an intermediate holder 7 supported on the tank cap 6. A valve 8 is screwed into the tank cap 6 and inserted therein.

Further, an operating lever 10 is supported on the neck of the gas jet nozzle 8a projecting outward from the upper end of the valve 8 so as to be able to swing up and down. This operation lever 10 is constructed by fitting the neck of the gas jet nozzle 8a into the through hole 10a, and placing the shield packing rubber 11 on top of the neck of the gas jet nozzle 8a.

It is attached to the upper surface of the flexible protrusion 16. Further, this protrusion 16 presses the lower end surface of the connecting fulcrum 2a that allows the lid 2 to be freely opened and closed, and when the lid is in the closed state, the lower end surface of the connecting fulcrum 2a is
6 and prevents the protrusion 16 from protruding. On the other hand, when the lid is open, the lower end surface of the connecting fulcrum 2a comes off the upper surface of the protrusion 16, and the protrusion 16
The operation lever 10 is allowed to protrude.
The valve 8 is moved in the direction of opening the valve 8 by lifting the open end 10a of the valve 8, and gas starts to be ejected.

Further, the annular joint 12 has a hook-shaped communication path inside which the bottom part and a part of the side surface communicate with each other, and an L-shaped nozzle 13 is connected to the side opening 12a of the joint 12 to direct the upper gas. It communicates with the ejection hole 14.

On the other hand, the intermediate holder 7 supported on the tank cap 6 is suspended from the horizontal substrate 7A and both longitudinal edges of the horizontal substrate 7A, and extends downward to fit into the engagement hole of the tank cap 6 (see FIG. (not shown)
It is formed into a cross-sectional shape with side plates 7B, 7B connected to engaging hooks 7b, 7b that are engaged with.

Further, on the upper surface of the horizontal substrate 7A, there is a horizontal hole 7c for horizontally holding a flint stone 18 and a spring 17 for urging the flint stone 18 toward the file 4, which will be described later.
A flint storage cylinder 7C equipped with a flint storage cylinder 7C is installed in series.

On the other hand, on one end side in the longitudinal direction of the intermediate holder 7, there is a projecting plate 7d ₁ extending from the top surface of the flint storage cylinder 7C toward the file 4 side, and a projecting plate 7d 1 that is perforated in the projecting plate 7d ₁ .

An insertion slit _7d3 , an ignition operator shaft hole _7e1 bored at one end in the longitudinal direction of the horizontal board 7A corresponding to the file shaft hole _7d2 , and a A pair of upper and lower locking pieces 7D, _7E each consisting of an ignition operator shaft insertion slit _7e2 bored along the widthwise edge of the horizontal board 7A so as to communicate with the ignition operator shaft hole 7e1.
is formed.

In the case of the intermediate holder 7 configured in this way, the file wheel 4 is rotatable in the horizontal direction.
By simply pressing between the pair of upper and lower locking pieces 7D and 7E, the support shaft columnar projection 4a of the file wheel 4 can freely rotate into the file shaft hole _7d2 via the file shaft insertion slit _7d3 . At the same time, the fixing columnar projection 4b interlocked with the ignition operator 3 is locked in the ignition operator shaft hole _{7e1 via the ignition operator shaft insertion slit 7e2} , and the ignition operator 3 is locked into the ignition operator shaft hole _7e1 . It is held by the intermediate holder 7 in a hanging state.

Moreover, the file wheel 4 interlocked with the ignition operator 3 is assembled with the flint 18 protruding from the horizontal hole-type flint storage tube 7C in a state where it can be ignited.
By simply pressing and fitting the intermediate holder 7 holding the ignition mechanism into the tank cap 6, a series of ignition mechanisms, in addition to the ignition operator 3, can be easily assembled into the predetermined positions of the lighter body 1. This simplifies the assembly process and makes it possible to assemble all at once, and allows automatic loading from above without using any fastening members such as mounting screws. Further, the outer surface of the intermediate holder 7 is covered with a metal interior cap 19 which also serves as a heat-resistant plate. In addition, in the figure, 9 is a core body, and 20 is a bottom cover.

In the gas lighter A configured as described above, when the lid 2 is opened, the protrusion 16 lifts the open end 10a of the operating lever 10 and operates in the direction of opening the valve 8 incorporated in the top of the gas tank 5, thereby releasing the gas. By spouting out gas and rotating the oxidation operator 3, sparks are generated and gas ignition is performed.
