Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a lighter that ignites fuel by scraping a flint with a file, and particularly relates to a flint supporting device for storing the flint.

[Conventional technology]

A conventional support device includes a flint storage body having a file shaft hole through which the shaft of a firing file passes, a flint storage hole perpendicular to the file shaft hole, and a guide surface parallel to the flint storage hole; A flint-pushing body having a flint-pushing piece having an outer shape that fits into the hole and an operation piece that comes into contact with the guide surface; and pushing the flint-pushing body along the flint storage hole in the direction of the file shaft hole. Spring member;
It is equipped with When attaching a new flint to this support device, drive the operating piece with your finger in a direction away from the file shaft hole along the flint storage hole against the pushing force of the spring member, and then continue to move the operating piece with your finger. If the used flint remains in the storage hole after pressing with the button, remove it from the storage hole, insert the unused flint into the storage hole, and release your finger from the operation piece.
When you release your finger, the operating piece is pushed by the repulsive force of the spring member, and the flint pusher presses the inserted flint against the file.

[Problem that the invention attempts to solve]

Flints are usually small, for example around 2mm in diameter,
Since it is a cylindrical body with a length of around 4 mm, the flint storage hole is correspondingly small and the operating piece is also small. Nevertheless, the spring force of the spring member is large enough to generate the required spark, and while the used flint is taken out from the flint storage hole and the unused flint is inserted into the storage hole, It is quite difficult to handle a small flint by holding down the operating piece with a finger while the spring member is compressed, and it is difficult to attach or replace the flint.

[Means for solving problems]

In order to achieve the above object, in the present invention, a groove 4 is formed, one end of which is continuous with a guide surface parallel to the flint storage hole, and the other end is lower than the guide surface, and the operating piece is
The outer shape is such that it can enter the groove 4.

[Effect]

According to this, when the operating piece is pressed down and driven with a finger in a direction away from the file shaft hole along the flint storage hole against the pushing force of the spring member, the operating piece retracts to the groove 4. At that point, it got stuck in groove 4,
Even if you take your finger off the operating piece, the operating piece will try to return due to the spring force, but it will stop when it hits the groove 4, so if you keep your finger off the operating piece and the used up flint remains in the storage hole. , take it out of the storage hole, insert an unused flint into the storage hole,
When you press down on the part of the operating piece that is not in the groove 4 and return the operating piece to its original position, the operating piece comes off from the groove 4 and is pushed by the repulsive force of the spring member, causing the ignition. The stone pusher presses the inserted flint against the file. Therefore, the flint can be removed or inserted by removing the finger from the operating piece.
It becomes extremely easy.

〔Example〕

Figures 1a and 1b show a gas lighter equipped with an embodiment of the present invention. Note that FIG. 1a is a side view showing the inside of the lighter with the lighter case 10 and the case lid 11 cut away.
1 is shown in a closed state. Figure 1b shows the case lid 11.
The figure shows a state in which the flint pusher 8 has been opened and the flint pusher 8 has been positioned at the retracted position in order to mount the flint.

A flint storage body 5 is fixed to the fuel tank 12 with screws 13. A file drive shaft passes through the shaft hole 1 of the storage body 5, a file 14 is engaged with this drive shaft, and an ignition control wheel 15 is engaged with the drive shaft. When the operating wheel 15 is rotated with a finger, the file 14 is rotated.

A compression coil spring 17 is inserted into a sleeve 16 fixed to the fuel tank, and a push rod 18 is supported by this spring 17, and this push rod 18 supports a connecting rod 19. The upper end of the connecting rod 19 is rotatably connected to the case lid 11. The case lid 11 is rotatably connected to the case 10 with a pin 20. As shown in FIG. 1a, when the case lid 11 is closed, the pushing rod 18 is driven upward by the repulsive force of the spring 17, and a counterclockwise rotational force is applied to the lower end of the connecting rod 19. As a result, a clockwise rotational force centered on the pin 20 is applied to the upper end of the connecting rod 19, and a clockwise rotational force centered on the pin 20 (case lid closing direction) is applied to the case lid 11. I'm joining in.

When an attempt is made to open the case lid 11 by applying a counterclockwise rotational force to the case lid 11 with a finger against this rotational force, the lower end of the connecting rod 19 is lowered, the spring 17 is compressed, and the connecting rod 19 The upper end of is the push rod 1
8, the repulsive force of the spring 17 acts on the case lid 11 in a counterclockwise direction, and the case lid 11 opens as shown in FIG. 1b.

In the process of opening the case lid 11 in this manner, the right end of the valve operator 2 engages with the locking piece 21 that stands up from the fuel tank 12, and the left end of the valve operator 2 rests on the upper surface of the push rod 18.
2 rotates clockwise as the push rod 18 rises, driving the gas discharge pipe 23 upward, thereby opening the valve in the fuel tank 12 and allowing fuel gas vaporized from the liquid fuel in the tank 12 to flow. The discharge pipe 23 is bent into a dogleg shape as shown in FIGS. 1a and 1b, and further bent into a dogleg shape on the back side of the storage body 5, so that the distal end is parallel to the file shaft hole 1 and stands upright. ing. Although the flint is not shown in the drawing, when the flint stored in the storage hole 2 is rubbed with the file 14 and generates a spark, the gas emitted from the tip of the tube 23 is ignited by this spark.

A pushing body 8 is attached to the flint storage body 5, and this pushing body 8 is pushed to the right by a coil spring 9. A flint (not shown) is inserted into the flint storage hole 2 shown in FIG.
Then, it is pressed against the file 14.

Fig. 2a (horizontal sectional view), Fig. 2b (vertical sectional view), Fig. 2c (transverse sectional view), and Fig. 2d (top plan view) show the flint storage body 5 in an enlarged manner.
In the storage body 5, a flint storage hole 2 is bored perpendicularly to the file shaft hole 1 through which the shaft of the file 14 passes, and the right end of this hole 2 is slightly larger than the outer diameter of the flint (not shown). Although it is a large circular hole, the left end is oval so that a push piece 6, which will be described later and enters the hole 2, can be tilted upward/downward. An opening 24 for inserting and removing a flint is continuous with this hole 2. There is a flat guide surface 3 and guide strips 25 ₁ , 25 ₂ on the upper surface of the storage body 5, but in the center of the guide surface 3,
A groove 4 inclined downward from the guide surface 3 is formed.

Note that the circumferential portion of the coil spring 9 is supported by the pin-shaped protrusion 26 on the leg portion of the storage body 5 .

Figure 3a (top plan view), Figure 3b (side view)
And FIG. 3c (left side view) shows an enlarged view of the flint pusher 8. The pushing body 8 is roughly composed of a pushing piece 6 and an operating piece 7. The pusher piece 6 is roughly as follows:
It is a cylindrical body with an external shape that can enter the hole 2, and the operation piece 7
has a shape that allows it to slide on the guide surface 3 between the guide strips 25 ₁ and 25 ₂ and to fit into the groove 4 . A rectangular portion 27 connecting the pushing piece 6, the operating piece 7, and the deflection is integral, and a groove 28 for engaging the spring leg is formed astride them.

From the right end of the push piece 6 of the push body 8 ((Fig. 3b),
Place the push piece 6 at the left end of the hole 2 of the storage body 5 (Fig. 2b).
When the push piece 6 is moved to the right, the rectangular portion 27 enters the guide groove 29. In this state, insert one leg of the coil spring 9 into the groove 28, and then
The other leg of the spring 9 is engaged with the small hole of the storage body 5 while the coil spring 9 is compressed by engaging the circumferential portion of the coil spring 9 with the pin-shaped protrusion 26 . As a result, the storage body 5, push body 8, and coil spring 9 are combined into one body. FIG. 1a shows the state in which the parts are combined and assembled into a lighter.

When attaching a flint (not shown), push the operating piece 7 to the left while pressing down with your finger. Then, when the right end of the operating piece 7 is above the groove 4, the right end of the operating piece 7 is lowered into the groove 4. At this point, when you release your finger from the operating piece 7, the right end of the operating member 7 hits the right end of the groove 4.
As shown in FIG. 1b, the pushing body 8 stops tilting downward to the right. In this state, the push piece 6 is
Since it is retracted to the left of the opening 24, if there is a flint in the hole 2, when you shake the lighter sideways, the flint will pass through the opening 24 and come out of the storage body 5 from the hole 2. . Since it is not necessary to hold the pusher 8 with fingers, such an operation is extremely easy. If there is no flint in the hole 2, or after taking the flint out of the opening 24 as described above, insert an unused flint from the opening 24 into the storage hole 2 with your fingers or with tweezers. ,insert. Then, the left end of the operating piece 7 of the pushing body 8 in the state shown in FIG. 1b is pushed down a little. This results in
The right end of the operating piece 7 moves upward from the position shown in Fig. 1b and comes out of the groove 4, and is driven to the right by the repulsive force of the spring 9, and when the flint is not put into the hole 2,
The state shown in the figure will be reached. When the flint is stored in the hole 2, the flint is positioned between the push piece 6 and the file 4, and the file 4 is pushed through the push piece 6 by the repulsive force of the spring 9.
be forced to.

[Effect of idea]

As described above, the flint supporting device of the present invention allows you to take out the flint from the storage hole 2 or insert a new one into the storage hole 2 while the pusher 8 is stationary at the retracted position and your finger is released from the pusher 8. Since a flint can be inserted, inserting and removing the flint is extremely easy.
