The displacement control means 6
By pressing and sliding the lid 2 to a desired position against the urging force of the above, the stepped portion 7a jumps over and engages with the engaging portion 7b, and the lid 2 is moved as shown in FIG. Then, in the unlocked state, it is temporarily held. This holding state is released by the lid 2 being displaced upward by the opening operation, and the lid 2 is moved to a predetermined position by the urging force of the displacement control means 6. The lid is opened while returning (see FIG. 5).

On the other hand, as shown in FIG.
A firing stone (not shown) is provided inside and a firing stone support cylinder 9 having a file wheel 8 rotatably mounted on an upper end thereof is held therein,
The cylindrical portion 9a of the igniter support cylinder 9 is
The upper large-diameter portion 9b is seated on the top surface of the lighter main body 1 by fitting into the vertical hole of the lighter main body 1 to thereby support the positioning of the valve operation lever 10 described later.

The valve operating lever 10 has, at its tip, a slit 10a engaged with the neck of the gas ejection nozzle 11, and an opening 10b through which the igniter support cylinder 9 is inserted. Is engaged with the gas ejection nozzle 11 and is swingably mounted via a pair of support beams 1b, 1b disposed on the top of the lighter main body 1. In other words, one end of the valve operating lever 10 is fitted with the neck of the gas ejection nozzle 11 through the slit 10a communicating with the outer peripheral edge thereof, and is connected to the other end. When the operating piece 10c is pressed down, the valve operating lever 10 is moved to the supporting beams 1b, 1b.

Next, by performing a conventional opening operation, that is, by opening the lid 2 with the thumb of the hand holding the lighter main body 1, the holding state is released and the lid is opened to a predetermined position. (See FIG. 5). Then, by performing a normal ignition operation, that is, by rotating the file wheel 6 and pressing down the operation piece 10c of the valve operation lever 10 as it is, the igniter is rubbed and a spark is emitted to the gas ejection nozzle 11 side. Occurs,
When the neck of the gas ejection nozzle 11 is operated in the extraction direction, the gas in a gas tank (not shown) is released from the gas ejection nozzle 1.
At the instant, the spark ignites to ignite to produce a flame of a desired length. Further, after ignition, the lock piece 2a and the lock engaging portion 4 are engaged with each other simply by closing the lid 2, and the original lock state is automatically maintained (see FIG. 3). ).

The open / close lock mechanism of the lighter with a lid according to the present invention is not limited to the present embodiment, but can be freely designed and changed within the scope of the present invention. It encompasses everything. For example, in the present embodiment, the lid 2 is unlocked by pressing and sliding the connecting shaft 3 side of the lid 2 toward the windshield 5, but the present invention is not limited to this. The lock shaft 2 may be assembled so that the lock can be released by pushing and sliding the connection shaft 3 side away from the windshield 5.

The lock engagement portion 4 may be separately erected and may be erected, or may be recessed so as to engage with the rear end of the valve operation lever 10 as shown in FIG. In this embodiment, a lock piece 2a is provided on the lid 2 and a lock engagement portion 4 is provided on the lighter body 1.
However, in order to reverse these, that is, the lock engaging portion 4 may be attached to the lid 2 and the lock piece 2a may be attached to the lighter main body 1.

Further, an urging member such as a coil spring is used as the displacement control means 6. However, the present invention is not limited to this. It is also possible to use a joining member (not shown) arranged in contact. In this embodiment, a flint type lighter is described. However, the present invention is not limited to this, and it goes without saying that the present invention can be applied to a piezo lighter.

[0023]

The present invention is constructed as described above, and locks the lid in the opening preventing state at a position where the lid is aligned with the top of the lighter body, and displaces the lid in the horizontal direction. A lock piece that releases the locked state when the cover is opened, and a displacement control unit that allows horizontal operation of the lid only when the lid is pressed in one direction with a predetermined force or more, and a lid opening operation. Return preventing means for holding the lid in the unlocked state until the lid is pressed in the unlocking direction with a force greater than a predetermined force against the displacement control means. Since a horizontal operation cannot be performed, a useful open / close lock mechanism for a lighter with a lid can be provided that can easily prevent unintended lock release and erroneous operation.

Further, the displacement control means has one end abutting on a windshield projecting from the top of the lighter body and the other end abutting on a connecting shaft for connecting the lid and the lighter body in an openable and closable manner. If the lid is constituted by a biasing member such as a spring, the lid is always urged in a direction away from the windshield, so that the lid is opposed to the biasing force of the biasing member to move the lid against the windshield. Unless pressed, the lock cannot be released,
Moreover, since the locking mechanism is not perceived from the appearance of the lighter and the locking and disengaging operation is performed only by horizontally operating the lid, even if the glance of the lighter does not mean that it also has the locking mechanism. Unexpectedly, it has the effect of being able to be attached to the lighter without the child realizing the existence of the lock mechanism, and the original design of the lighter can be used as it is, without mischievously damaging the appearance of the lighter.

[0025] Preferably, said opening / closing lock mechanism is provided with said lid mounted to be displaceable in the horizontal direction.
A lock piece attached to the lid, a lock engaging portion attached to a desired position of the lighter body corresponding to the lock piece, and an urging member for urging the lid in one direction. The lock piece is engaged with the lock engagement portion at an alignment position between the lid and the top of the lighter main body, thereby preventing the lid from being opened, and resisting the urging force of the urging member. When the lid is displaced in the horizontal direction, the engagement between the lock piece and the lock engagement portion is released, and the step portion mounted on the inner wall surface of the lid and the lighter body are fixed. An engaging portion protruding from the portion engages to hold the lid in an unlocked state, and the stepped portion and the engaging portion are engaged by opening the lid. If it is assembled so as to be released, the lid that is always kept in the locked state is pushed by the urging force of the urging member. By pressing in the unlocking direction in opposition, the lid is displaced in the horizontal direction for the first time to be in a state where the lid can be opened, and at this time, even if the finger pressing the lid is released, Since the step provided on the inner wall surface of the lid is engaged with the engagement portion, the lid is temporarily held in the unlocked state without returning to the original position, so that a series of ignitions Inconveniences such as the lid returning to the original locked state immediately during operation can be resolved, and the lid is automatically returned to the original locked state by the closing operation after use of ignition, which is contrary to wishes You can now unlock or forget to lock.

Moreover, the present invention has the effect that the number of parts other than the displacement control means is not forced to increase, and the lock mechanism can be easily constructed simply by assembling normal parts. This eliminates the necessity of assembling the locked components.

As described above, since the lock mechanism for opening and closing the lighter with the lid according to the present invention can be assembled with the lock mechanism in order to effectively use the dead space, the lock mechanism is bulky and the overall shape of the lighter becomes complicated. It can be easily and reliably opened with the minimum number of parts (only the biasing member of the displacement control means) without impairing the appearance of the The lid operation can be prevented, and the locked state can be easily released with only one hand (with only one index finger), and it can automatically return to the original locked state when the lid is closed after using ignition It is possible to provide an opening / closing lock mechanism for a lighter with a lid that also has an auto return function.

The open / close lock mechanism of the present invention has a simple structure, so it is suitable for mass production, and can be supplied at low cost to consumers. It is large and can meet the needs of disposable lighters.
