Description

[Detailed Description of the Invention] This invention relates to a flint inserting and pressing mechanism for inserting and pressing a flint in a lighter.

Conventionally, a firing file was rotatably supported on a vertical axis,
A flint pressing mechanism is provided with a cylindrical flint storage cylinder extending in a horizontal direction orthogonal to the firing file, and presses the flint against the firing file under the tension of a spring within the storage cylinder. As is well known, in such a flint pressing mechanism, it is necessary to easily refill the storage cylinder with flint when the flint is used up.

In order to facilitate refilling with flint, a part of the flint storage cylinder is opened upward, and the flint is stored in a flint pressing member that slides under the tension of a spring within the flint storage cylinder. A slide plate located on the top surface of the cylinder and capable of opening and closing the opening is connected together, and by retracting the slide plate backward from the ignition file with your finger against the tension of the spring, the opening is opened and the ignition is started. An example of a flint insertion and pressing mechanism in which a stone pressing member is temporarily locked in a retracted position is disclosed in Utility Model Registration No. 1234744.

In the flint insertion and pressing mechanism disclosed in this registered utility model No. 1234744, when the slide plate is retracted with a finger, the flint pressing member is inserted into the step provided inside the flint storage cylinder. Since the opening remains open even when the slide plate is engaged with the slide plate and the finger action is released, the flint is inserted into the flint storage cylinder through the opening and the flint is refilled. Easy to fill.

However, with this registered utility model, there are manufacturing difficulties in forming a stepped part that locks the flint pressing member in the flint storage cylinder, and the locking state is unstable and is often There was a drawback that the alignment was incorrect.

This invention was made in order to eliminate the drawbacks of the conventional flint insertion and pressing mechanism, and will be described in detail below with reference to the drawings.

In the figure, reference numeral 1 denotes an ignition mechanism protrusion installed on the upper surface of a fuel tank 3 housed in a casing 2,
On the - side, the upper part of a rotating wheel 4 whose lower end is supported by the fuel tank 3 and is rotatable on a vertical axis is supported.

A flint storage groove 5 extending horizontally is formed in the upper part of the block body 1.

The upper surface of the flint storage groove 5 is opened, and the groove 5
A firing file wheel 6 attached to the upper end of the rotary wheel 4 is located at one end, and a portion of the lower wall of the groove 5 receives a spring to be described later, and has enough space for the spring to move. It is opened lower with a large size.

A 5-pushing member 8 is inserted into the flint storage groove 5 from the rear of the groove so as to be slidable horizontally along the groove 5.

The 5-pushing member 8 is engaged with an engaging protrusion 9 formed at the upper part of both side walls of the flint storage groove 5 and slightly protruding inward, thereby being prevented from being pulled out upward. .

As shown in the figure, the engaging protrusion 9 has a substantially thin plate shape extending in the longitudinal direction of the flint storage groove 5, and is connected to the flint insertion opening 1.
It is terminated in the middle to form 0.

The lower edge of the engaging protrusion 9 is formed in a horizontal plane parallel to the horizontal axis of the flint storage groove 5, while the upper edge of the engaging protrusion 9 has a rear edge facing away from the ignition file wheel 6 facing downward. It is formed on a slope 11 that slopes toward the top.

However, the slope 11 may be formed by obliquely cutting off the upper part of the flint storage groove 5, that is, a part of the upper surface of the block body 1.

5 Pushing member 8 includes a plate-shaped lid portion 12 that can close the open upper surface of the flint storage groove 5, and a flint pressing portion that is located in the groove 5 and presses the inserted flint against the flint file wheel 6. 13 and a stopper part 14, the pressing part 13 and the stopper part 1
4 is integrally connected to the lid part 12 by a plate-shaped connecting part 15 that passes through a narrow gap between the engaging protrusions 9, 9.

A portion of the pressing portion 13 and a portion of the stopper 14 can move within the flint storage groove 5 along the groove, but the engaging protrusion 9,
The gap 9 is formed in a cylindrical body with a diameter that cannot be passed through.

One end of a spring 16 that urges the 5-pushing member 8 toward the firing file wheel 6 is stretched on the rear end surface of the suppressing portion 13 .

The spring 16 has its base supported by a support shaft 17 integral with the block body 1 at the lower part of the flint storage groove 5, and one end is stretched through the open lower part 5 and the pushing member 8 as described above, and the other end is It is locked to the lower wall 18 of the block body 1.

A retaining portion 19 is formed at the rear end of the bottom wall of the flint storage groove 5 to lock the stopper part 14 and stop the 5 pushing member 8 at a position where it is retreated from the flint file wheel 6. With the 5-pushing member 8 retracted, the flint insertion opening 10 of the flint storage groove 5 is opened for insertion of a flint.

FIG. 1 shows the state in which the lighter is in use, with the flint 20 pressed against the ignition file wheel 6 by the 5 pushing member 8.
The pushing member 8 is biased toward the flint file wheel 6 within the flint storage groove 5 under the tension of the spring 16, and the lid portion 12 closes the upper part of the flint storage groove 5 including the flint insertion opening 10. ing.

Next, in order to reload the flint 20, finger pressure is applied to the lid 12, and the pushing member 8 is moved back from the pyrotechnic file wheel 6 against the tension of the spring 16.

5 As the pushing member 8 retreats within the flint storage groove 5,
The lower surface of the lid part 12 tilts downward along the slope 11 of the engagement protrusion 9.

When the stopper part 14 exceeds the retaining part 19, the stopper part 14 is locked to the engaging part 19, and even if the finger pressure on the lid part is released, the 5-pushing member 8 is not moved back. maintained in condition.

Since the flint insertion port 10 is open in this state, the flint 20 can be inserted into the storage groove 5 through the port 10 and reloaded.

After loading the flint 20, the lid 1 of the 5-pushing member 8 is tilted.
When the front end of 2 is pressed down with a finger, the stopper part 14 is disengaged from the engaging part 19, and the pushing member 8 returns to the state shown in FIG. 1 under the tension of the spring 16, causing the pushing part 13 to fire. stone 2
0 is pressed against the firing file wheel 6 to restore it to a usable state.

As described above, according to the flint insertion and pressing mechanism of this invention, when the 5-pushing member 8 is moved backward from the pyrotechnic file wheel 6 to reload the flint 20, the 5-pushing member 8
The stopper part 14 naturally tilts downward along the
is engaged with the retaining portion 19, so it is extremely easy and reliable to shift the 5-pushing member 8 to the flint reloading position and maintain it in that position. The transition to can be performed only by moving the 5-pushing member 8 backwards, and there is no need to swing the 5-pushing member 8 in a direction perpendicular to its movement direction, and the movement of the 5-pushing member 8 is extremely simple. It becomes smooth.

Further, the slope 11 and the engaging portion 19 for tilting or locking the pushing member 8 are exposed to the outside or are located close to the open end of the flint storage groove 5. Because of this, the machining is easy and manufacturing costs can be reduced.
