TECHNICAL FIELD OF THE INVENTION
The present invention relates to a gas lighter that ignites fuel with sparks generated by rubbing a flint with a file ring.
[0002]
[Prior art]
In this type of writer, the rubbing surface of the file wheel is exposed at the position where it touches the user's finger. The wheel rotates and rubs the flint.

Japanese Patent Application Laid-Open No. Hei 6-341640 also discloses a firing device in which a ratchet wheel is connected to a file wheel so that the ratchet wheel is turned by the forward movement of the reciprocating operation element.
[0003]
[Problems to be solved by the invention]
In the case of a writer who uses a finger ring to turn the file ring directly with the finger, the rubbing surface is a file that easily ignites the sparks by rubbing the flint. Is not good. The file ring is small and difficult to turn. It is difficult to achieve a balance between the user's operability of the file wheel and the stability of ignition by the file wheel.
[0004]
In the lighters described in Patent Documents 1 to 4, the user only has to push down the reciprocating operation element and perform forward driving. However, there is a return spring for driving the reciprocating operation element backward and compresses the forward operation. Therefore, a strong operation force is required. It is different from the operation feeling of the finger turning similar to the conventional one. At the time of return drive, the reciprocating operation element is supported so as to swing in the direction away from the ratchet wheel so that the ratchet wheel connected to the file wheel does not return and rotate, and this support structure becomes complicated, and the operation of the operation element becomes complicated. Easy to be unstable.
[0005]
SUMMARY OF THE INVENTION An object of the present invention is to provide a finger-turning igniter lighter capable of improving ignition operability and ignition stability and increasing design flexibility.
[0006]
[Means for Solving the Problems]
(1) In a pyrotechnic lighter that ignites fuel by a pyrotechnic stone (12) and a file ring (13) rubbing it,
A driven gear (23) coupled to the file wheel (13) with the same rotation axis, an operating wheel (6) driven by a user to rotate, and an operating wheel (6) coupled to the operation wheel (6) with the same rotation axis. A igniter lighter comprising: a drive gear (21) for rotationally driving the driven gear (23).
[0007]
In addition, in order to facilitate understanding, reference numerals corresponding to corresponding or corresponding elements or members of the embodiment shown in the drawings and described later are added in parentheses for reference. The same applies to the following.
[0008]
According to this, when the user turns the operation wheel (6) with a finger, the driving gear drives the driven gear (23) to rotate, whereby the file wheel (13) rotates similarly to the driven gear (23). Rub the igniter stone. This rubbing causes sparks to scatter from the igniter and fuel is ignited. The operating wheel (6) can be designed to match or be part of the design of the lighter, and to be of a size and surface condition that allows the user to smoothly and reliably perform the turning operation. On the other hand, the file wheel (13) can be designed to have a shape and a surface state that can surely scatter sparks from the igniter (13). Since the operating wheel (6), the driving gear (21), the driven gear (23) and the file wheel (13) are all rotating mechanisms around the shaft, the operation is smooth and the operation stability is high. When a conventional reciprocating operation element is used, a return spring is necessary, but it is not necessary, and a strong force for compressing the return spring is not required.
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
(2) In a pyrotechnic lighter that ignites fuel by a pyrotechnic stone (13) and a file ring (13) rubbing it,
A driven gear (23) coupled to the file wheel (13) with the same rotation axis; an operating wheel (6) driven by a user to rotate; and a driven gear coupled to the operation wheel (6) with the same rotation axis. A driving gear (21) for rotating and driving the gear (13), and a driving force of the driving gear (21) is meshed with the driving gear (21) and the driven gear (13) so that the driving force is applied to the driven gear (13). A igniter lighter comprising an intermediate gear (22) for transmitting.
[0010]
The rotation speed at which the user smoothly turns the operation wheel (6) does not match the rotation speed of the file wheel (13) for the igniter (13) to reliably generate a spark. By adjusting the gear ratio of the driving gear (21) and the driven gear (23), the rotational speeds of the two can be individually set to appropriate values. However, the location and size of the gear storage space are limited by the shape of the lighter. Therefore, the gear ratio (gear size) is limited. In this embodiment, since the intermediate gear (22) is used, the degree of freedom in designing the driving gear (21) and the driven gear (23) is increased.
[0011]
(3) The igniter lighter according to (2), wherein the intermediate gear (22) is below the drive gear (21) and beside the driven gear (23). Since a relatively large space can be set below the operation wheel (6), by arranging the intermediate gear (22) there, a relatively large-diameter intermediate gear (22) can be used, and the drive The design freedom of the gear (21) and the driven gear (23) is high.
[0012]
(4) There is a pyrotechnic stone (12) between the fuel nozzle (8) for discharging fuel gas upward and the intermediate gear (22), and the file wheel (13) is placed on the pyrotechnic stone (12). The igniter lighter according to the above (3). Since the direction in which the ignition stone (12) is generated and the spark travels across the upper end of the nozzle is away from the intermediate gear (22), there is a possibility that the intermediate gear (22) may be contaminated by the ignited debris (powder). Low.
[0013]
Other objects and features of the present invention will become apparent from the following description of embodiments with reference to the drawings.
[0014]
【Example】
FIG. 1 shows the appearance of the igniter lighter of the present invention. An inner lid 3 is fitted into an upper opening of the outer case 1 which is closed by the outer lid 2. The inner lid 3 has a flame opening 4 and an air opening from which fuel gas ejected from an internal fuel nozzle is emitted. A part of the circumferential surface of the operation wheel 6 is exposed from the inner lid 3. By opening the outer lid 2 and turning the operating wheel 6 as shown in FIG. 1, the flame in which the fuel gas is burned rises from the flame opening 4.
[0015]
FIG. 2 shows an enlarged cross section of the lighter shown in FIG. 1 with the outer lid 2 closed. When the outer lid 2 is opened, at the beginning of the rotation of the outer lid 2 in the counterclockwise direction, the outer lid connecting shaft of the pushing trunk 11 crosses right below the rotating axis of the outer lid 2 from left to right, and the pushing trunk 11 is moved. The lower support 10 is driven upward by the repulsive force of a compression coil spring (not shown) to push up the push stem 11. Thereby, the rotation of the outer lid 2 in the counterclockwise direction is accelerated, and the outer lid 2 is opened as shown in FIG. In this process, the push stem 11 rises, and the gas release lever 9 that has been pushed down by the push stem 11 can be moved upward. The nozzle 8 is driven upward by the repulsive force, thereby opening a gas flow path below the nozzle 8, and the fuel gas in the fuel tank 7 flows upward from the upper end of the nozzle 8. On the right side of the nozzle 8, there is a flint (ignite) 12 and a file ring 13 sliding on the upper surface thereof.
[0016]
FIG. 3A is an enlarged view of a mechanism for driving the file wheel 13, and FIG. 3B is a side view of the mechanism seen from the right. A driven gear 23 is fixedly attached to the file wheel 13, and the file wheel 13 and the driven gear 23 can be integrally rotated about a pin that passes through both. An intermediate gear 22 having a pin penetrating therewith meshes with the driven gear 23. This intermediate gear 22 is also rotatable about the pin. A drive gear 21 is formed integrally with the operation wheel 6, a part of which is exposed from the inner lid 3, and the operation wheel 6 and the drive gear 21 can be integrally rotated around a pin passing through both. An intermediate gear 22 meshes with the drive gear 21. Each pin, which is a shaft passing through the center of each of the gears 21 to 23, is rotatably supported by a support frame 24 (FIG. 2) inside the inner lid 3.
[0017]
When the user puts his / her thumb on the portion of the operation wheel 21 exposed outside the inner lid 3 and turns the operation wheel 21 in the direction of the arrow Ar (clockwise), the intermediate gear 22 is thereby turned counterclockwise. To rotate the driven gear 23 clockwise. As a result, the file wheel 13 turns clockwise similarly to the driven gear 23, and rubs the upper end surface of the flint 12, whereby a spark is generated and the spark flows from the upper end of the flint 12 to the left. Due to this spark, the fuel gas flowing upward from the upper end of the nozzle 8 (FIG. 2) is ignited, becomes a flame, and exits upward from the flame opening 4.
[0018]
When the user closes the upper lid 2, the push stem 11 descends and pushes the lever 9 downward, whereby the nozzle 8 is lowered, the gas outlet at the lower part of the nozzle 8 is closed, and the outflow of gas stops.
[0019]
The operating wheel 6 can be designed to match or be part of the lighter design, and to be of a size and surface condition that allows the user to smoothly and reliably perform the turning operation. On the other hand, the file wheel 13 can be designed to have a shape and a surface state in which sparks are surely scattered from the igniter 13. Since the operating wheel 6, the drive gear 21, the intermediate gear 22, the driven gear 23, and the file wheel 13 are all rotation mechanisms around the shaft, the operation is smooth and the operation stability is high. When a conventional reciprocating operation element is used, a return spring is required, but it is not required, and a strong force for compressing the return spring is not required.
[0020]
In this embodiment, since the intermediate gear 22 is used, the degree of freedom in designing the driving gear 21 and the driven gear 23 is increased. Since a relatively large space can be set below the operation wheel 6, the intermediate gear 22 is arranged there. Thus, the intermediate gear 22 having a relatively large diameter can be used, and the drive gear 21 and the driven gear 23 have a high degree of freedom in design. Since the direction in which the flint 12 is generated and the spark travels across the upper end of the nozzle 8 is away from the intermediate gear 22, the intermediate gear 22 is less likely to be contaminated with the ignited debris (powder).
