Abstract

PURPOSE: To enhance ignition efficiency by moving a movable member at a stroke by an elastic force of a pressure-stored drive elastic member in the forced direction and turning a ratchet and a rotary ignition means. CONSTITUTION: A slide member 51 is engaged with a movable member 45 until a forcing operation member 41 is forced in by a definite quantity while a drive elastic member 49 stores its elastic pressure between the forcing operation member 41 and the movable member 41. When the forcing operation member 41 is forced in beyond the definite quantity, them forcing operation member 41 pushes back the slide member 51 against the elastic force of the elastic member 49, thereby releasing the engagement between the slide member 51 and the movable member 45. Therefore, the movable member 45 moves in the forced direction at a stoke by the elastic force of the pressure-stored elastic member 49, thereby turning a rotary member 13 and engaging a locking claw 17 with ratchet teeth 18 of a ratchet 12 and then turning the ratchet 12 and a rotary ignition means. This construction makes it possible to enhance ignition efficiency by rubbing an ignition stone to ignite.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ignition device, and
The structure for rotating the rotary ignition means such as a rotary file is improved, and the manufacturing is easy. For example, when applied to a gas lighter, the gas lighter itself can be easily downsized. It is possible to improve the ignition efficiency.

[0002]

2. Description of the Related Art Conventionally, there are the following flint type gas lighters. First, there is the lighter body,
A vaporized gas discharge nozzle is provided on the upper part of the lighter body, and a rotary file having a file surface on the peripheral surface is rotatably attached. Further, a flint is internally provided in the lighter body, and the flint is elastically contacted with the rotating file by a spring. An operation button for rotating the rotary file is attached to the upper part of the lighter body. Further, the side surface of the rotary file is provided with equally-divided (for example, 5 equally divided) divided portions, and each of these divided portions is formed with a locking step portion. Further, on the operation button side, there is provided a spring piece having a locking claw that is releasably locked to the locking step of the dividing section.

In the above structure, when using the gas lighter, first, the operation button is pushed down. By depressing this operation button, the locking claw of the spring piece is locked to the locking step portion of the arbitrary division portion, thereby rotating the rotary file. By the rotation of the rotary file, the igniting stone pressed against the file surface is rubbed and the friction is ignited. The vaporized gas discharged from the discharge nozzle by the ignition is ignited.

[0004]

The above-mentioned conventional structure has the following problems. That is, as a configuration for rotating a rotary file in a conventional gas lighter, a partition portion is formed on the side surface of the rotary file, and a locking step portion is formed on each partition portion. It is necessary to provide a spring piece formed with a locking claw. that time,
There is a problem that it is difficult to form the divisions. That is, when manufacturing a rotary file, for example, a metal wire is cut into a predetermined length, and the cut piece is pushed into a predetermined die for forging. In that case, in order to provide the above-mentioned division part, it is necessary to provide a shape corresponding to it in the mold, and it is extremely difficult to process the mold including manufacturing the mold. Therefore, there has been a problem that a large number of man-hours are required in manufacturing and the product cost becomes high.

Further, the number of divisions in the division section is limited to about 5 equal parts. This is because the shape of the mold becomes more complicated in order to divide it more finely.
However, in the case of division into 5 equal parts, there is a problem that the rotation angle for rotating and moving one division part becomes large, and accordingly, the amount of pressing the operation button must be increased. In order to reduce the pressing amount of the operation button, it is sufficient to increase the number of divisions, but in that case, as described above, there is a problem in manufacturing such as a complicated mold shape. There was a problem of being lost.

The present invention has been made on the basis of the above point, and an object thereof is to improve the structure for rotating a rotary ignition means such as a rotary file, thereby facilitating the manufacture thereof. An object of the present invention is to provide an ignition device capable of reducing the number of steps required for reducing the cost and rotating the rotary ignition means efficiently to significantly improve the ignition efficiency.

[0007]

In order to achieve the above-mentioned object, an ignition device according to the present invention includes an ignition device body for accommodating a fuel and having a fuel discharge means, and an ignition device body which is pushably attached to the ignition device body for resetting. A pushing operation member that is urged in the anti-pushing direction by an elastic member, and a rotation that is rotatably attached to the ignition device body and is rubbed against the ignition stone by rotating and causing the ignition stone to rub and ignite. The pushing operation member includes an ignition means, a ratchet coaxially attached to the rotary ignition means and provided with a plurality of ratchet teeth, and a ratchet coaxially and rotatably attached to the ratchet and having a locking claw. When it is pushed for a certain amount or more, it is rotated and the locking claw is locked to the ratchet teeth of the ratchet, and the ratchet and rotary ignition means are rotated to perform the pushing operation. A rotating body that rotates in the opposite direction by releasing the pushing operation of the member to release the locking of the locking claw to the ratchet teeth, and is housed in the pressing operating member so as to be movable in the pressing direction and also rotates. A moving body communicating with the moving body, a drive elastic member disposed between the moving body in the pushing operation member, and a moving member that is constantly urged toward the moving member by the elastic member. When the pushing operation member is pushed to a certain amount by stopping, the lowering of the moving member is regulated, and when the pushing operation member is pushed by a certain amount or more, the pushing operation member resists the biasing force of the elastic member and the anti-moving member. A slide member that is pushed back to the side to allow the moving elastic member to move in the pushing direction by the accumulated elastic force of the driving elastic member. At that time, a taper surface is formed on the slide member side, and on the other hand, a taper surface is also formed on the pushing operation member side, and the taper surface is slid by pushing the pushing operation member by a certain amount or more. It is conceivable that the sliding member comes into contact with the tapered surface on the member side, and thereby pushes the slide member back to the side opposite to the moving member against the biasing force of the elastic member. Further, it is conceivable that the slide member is always biased toward the moving member by a separately provided elastic member. Further, the slide member integrally includes a pair of elastic pieces, a stopper member is disposed between the pair of elastic pieces, and the pair of elastic pieces is normally closed, and the slide member is a stopper member. When the slide member is moved in one direction to the position regulated by the vertical direction, and the moving force in the other direction acts on the slide member, the pair of elastic members are expanded along the stopper member against the elastic force of the pair of elastic pieces. It is conceivable to configure it to move while opening it.

[0008]

In operation, the pushing operation member is first pushed in against the elastic force of the restoring elastic member. The sliding member is engaged with the moving member until the pushing operation member is pushed by a certain amount, so that the moving member does not move in the pushing direction, and during that time, the drive elastic member acts as the pushing operation member and the moving member. The pressure will be accumulated between. When the pushing operation member is pushed by a certain amount or more, the pushing operation member pushes the slide member back against the elastic force of the elastic member, whereby the engagement relationship between the slide member and the moving member is released. As a result, the moving member is moved in the pushing direction all at once by the elastic force of the driving elastic member that has accumulated pressure. The rotary body is rotated by one movement of the moving member, whereby the locking claw is locked to the ratchet teeth of the ratchet, and the ratchet and the rotary firing means are rotated. As a result, the igneous stone is rubbed and ignited. Further, when the use is stopped, the pushing operation of the pushing operation member may be stopped, whereby the pushing operation member is returned to the original position by the elastic member for return, and the rotating body and the ratchet are also in the original positions. Return to.
In addition, it is considered that the slide member and the pushing operation member are contacted with each other by providing a tapered surface on both of them to make the operation smooth. Various configurations are conceivable as the configuration of the elastic member that biases the slide member. For example, as shown in claim 3, the slide member is always biased toward the moving member by an elastic member separately provided. It is conceivable to configure it as follows. Further, as described in claim 4, a configuration in which a pair of elastic pieces as elastic members are integrally provided on the slide member and a stopper member is arranged between the pair of elastic pieces can be considered. In this case, the pair of elastic pieces are normally closed, and the slide member moves in one direction to the position regulated by the stopper member. On the other hand, when a moving force in the other direction acts on the slide member, the pair of elastic members move while being expanded along the stopper member against the elastic force of the pair of elastic pieces. Become.

Next, the structure of the operation button 6 will be described. The operation button 6 is configured as shown in FIG. First, there is a pressing operation member 41, and a rod body 42 is projectingly provided under the pressing operation member 41, and a return coil spring 43 as a return elastic member is provided on the outer peripheral side of the rod body 42. It is installed. A moving member 45 is movably accommodated and arranged in the pressing operation member 41.
The moving member 45 is provided with a pair of projecting pieces 46, 46. The distal ends of the projecting pieces 46, 46 are engaged with an engaging hole 47 for engaging the locking shaft 23 on the file cover 16 side. Four
7 is perforated (only one side is shown in FIGS. 4 to 6). A drive coil spring 49 as a drive elastic member is mounted between the moving member 45 and the pressing operation member 41.

On the other hand, below the moving member 45, a slide member 51 having a tapered surface 51a is arranged so as to be movable in the horizontal direction (the direction indicated by the arrow c) in the drawing.
A coil spring 52 as an elastic member urges the coil spring 52 to the left in the figure to a position where it comes into contact with a stopper (not shown). Further, on the pressing operation member 41 side, the tapered surface 53a
The action portion 53 having the above is projected.

The operation will be described based on the above configuration. First, when not in use, the state is as shown in FIG. That is, the lower end of the moving member 45 is in contact with the slide member 51. Next, when using a gas lighter, as shown in FIG.
When the pressing operation is performed in the direction indicated by, the pressing operation member 41 moves in the pressing direction. On the other hand, since the lower end of the moving member 49 is in contact with the slide member 51, the moving member 49 is restricted from moving in the pressing direction. As a result, the driving coil spring 49 is compressed, and the spring force is accumulated. Then, when the pressing operation member 41 is further pressed and moved, as shown in FIG. 5, the action portion 53 of the pressing operation member 41 contacts the tapered surface 51a of the slide member 51 via the tapered surface 53a, Slide member 5
1 is pushed back in the right direction in the figure against the biasing force of the coil spring 52.

Then, the slide member 5 is moved to a position where the lower end of the moving member 45 and the slide member 51 are disengaged.
When 1 is pushed back, the state shown in FIG. 6 is reached, and at that time, the movement of the moving member 45 in the pushing direction is permitted. Then, the accumulated spring force of the driving spring 49 is released at once, and the moving member 45 is moved at once in the pushing direction. This moving member 4
By the movement of 5 at once, the rotary file side also rotates at once. That is, the engaging hole 47 of the moving member 45,
The locking shaft 23 is pushed down via 47, and the file cover 16 rotates in the direction indicated by the arrow a in FIG. By the rotation of the file cover 16, via the link holes 15 of the file cover 16 and the shafts 14 of the elastic claw 13,

8 and 18 thereby causing the file shaft 11 to rotate.

The rotation of the file shaft 11 causes the rotary file 4 to rotate, whereby the file body 1 of the rotary file 4 is rotated.
The igneous stone 5 elastically contacted with 0 is rubbed to generate a spark. Then, the vaporized gas released from the gas releasing means 2 is ignited and ignited. On the other hand, when the use of the gas lighter is stopped, the finger may be released from the pushing operation member 41. By releasing the finger from the pushing operation member 41,
The pushing operation member 41 is returned to the original position by the return coil spring 43. Thereby, the engagement holes 47, 4
7, the file cover 16 is rotated in the opposite direction to the above (direction indicated by arrow b in FIG. 3) via the locking shaft 23. By rotating the file cover 16 in the opposite direction,
The locking claws 17, 17 of the elastic claw body 13 are disengaged from the ratchet teeth 18, 18 of the ratchet 12 to be in a free state and return to the original state. At that time, the rotary file 4 does not rotate.

According to the present embodiment, the following effects can be obtained. First, the manufacturing of the components for rotating the rotary file 4 is facilitated, whereby the man-hour required for the manufacturing can be reduced and the cost can be reduced. This is because the ratchet 12 and the elastic claw 13 which are the main components for rotating the rotary file 4 are, for example,
This is because it is possible to mold even finer parts by resin molding, etc., and it is extremely easy to manufacture compared to the conventional processing in which a division part is provided on the side surface of a rotary file formed by forging a metal wire rod. Because it will be something. And, since it is easy to manufacture, it is possible to increase the number of ratchet teeth 18 of the ratchet 12, thereby,
The pushing amount of the operation button 6 can be reduced, and yet the locking operation of the locking claws 17 of the elastic claw body 13 with respect to the ratchet teeth 18 will not be impaired.

Further, the driving coil spring 49 accumulates the repulsive force due to the compression, and the repulsive force is released all at once to act on the rotary file 4 side, and the ignition is caused by the sliding contact friction between the flint 5 and the file body 10. Since the configuration is adopted, the rotary file 4 can be instantly rotated at a high speed, and the ignition efficiency is increased accordingly. Even in the flint type ignition device using the flint 5 and the rotary file 4, it becomes possible to obtain reliable ignition by the same operation method as that of the piezoelectric type or the battery type ignition device. Since the ignition energy and the adjustment of the ignition device are not required as compared with the battery type and the battery type, the manufacturing defect rate of the ignition device is low, and the effect is obtained. Further, since the slide member 51 and the action portion 53 of the pushing operation member 41 are formed with the tapered surfaces 51a and 53a, respectively, the operation of moving the slide member 51 against the spring force of the coil spring 52 is smoothly performed. It will be.

Next, a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, the structure of the slide member 51 and the structure for operating the slide member 51 are changed. First, as shown in FIG. 7, the slide member 51 is bifurcated and has a pair of elastic pieces 61, 6
It is equipped with 1. These pair of elastic pieces 61, 61
Is configured to exert a spring function by itself, and engaging portions 61a, 61a are formed at the tips thereof, respectively. Further, a stopper member 63 is provided, and the stopper member 63 is also formed with a pair of engaging portions 63a, 63a, respectively.

First, when the gas lighter is not used, the state is as shown in FIG. That is, the slide member 51 is in a state of returning to the left side in FIG. 7 by the elastic return force of the pair of elastic pieces 61, 61, and at that time, the engaging portion 61.
The a and 61a are engaged with the engaging portions 63a and 63a, and the further movement of the slide member 51 to the left side in the drawing is restricted. On the other hand, when the pushing operation member 41 is pushed to use the gas lighter,
As described in the first embodiment, only the pushing operation member 41 is pushed in, and then the tapered surface 53a of the action portion 53 of the moving member 45 is changed to the tapered surface 5 of the slide member 51.
1a and slide the slide member 51 into a pair of elastic pieces 61,
Against the elastic force of 61, it is gradually pushed to the right side in FIG. The situation is shown in FIG.

As shown in FIG. 8, a pair of elastic pieces 61, 6 are provided.
1 gradually expands along the tapered surfaces 63b, 63b of the stopper member 63. The movement of the slide member 51 releases the accumulated spring force of the driving coil spring 49 at once, and a series of ignition operations are performed, as in the case of the first embodiment. And
Push operation member 41 to stop the use of the gas lighter
When the pushing operation against the slide member 51 is stopped,
Is returned to the original position shown in FIG. 7 by the elastic return force of the pair of elastic pieces 61, 61.

Therefore, the same effect as that of the first embodiment can be obtained, and since the slide member 51 itself is provided with the spring function, the number of parts can be reduced accordingly.

The present invention is not limited to the first and second embodiments. First, in each of the above-described embodiments, an example in which the ignition device according to the present invention is applied to a gas lighter is shown. However, the invention can be similarly applied to those requiring similar ignition means other than the gas lighter. The fuel is not limited to gas. Further, the configuration for moving and returning the slide member is not limited to the illustrated one.

[0025]

As described above in detail, according to the ignition device of the present invention, it becomes easy to manufacture the component parts, thereby reducing the man-hour required for the manufacture and the cost. That is, the ratchet and the rotating body, which are the main components for rotating the rotary ignition means,
This is because, for example, it is possible to mold even finer parts by resin molding, etc., and compared with the conventional processing in which a division part is provided on the side surface of the rotary file formed by forging a metal wire rod, the manufacturing is extremely difficult. Because it will be easy. And because of the ease of manufacture, it is possible to increase the number of ratchet teeth on the ratchet, thereby
The pushing amount of the pushing operation member can be reduced. Further, since the elastic member for driving accumulates the repulsive force due to the compression, the repulsive force is released at once, and the repulsive force is acted on the rotary ignition means side through the rotating body and the ratchet. Can be instantly rotated at a high speed, and the ignition efficiency can be increased accordingly. or,
When the slide member and the pushing operation member are provided with tapered surfaces, respectively, the operation becomes smoother. Further, when the pair of elastic pieces are integrally formed with the slide member, the number of parts can be reduced by that amount as compared with the case where a separate elastic member is provided.
