[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an operation lock for a lighter (oil lighter, piezo lighter, flint type lighter) which can prevent the opening and closing operation of a lid covered on the top of the lighter or the ignition operation of an ignition operator. It relates to improvement of the device.

[0002]

2. Description of the Related Art Generally, a gas lighter is operated such that a gas ejection nozzle is operated by a depression operation of an ignition operation element to start gas ejection, and a spark is generated by operating an ignition means to ignite gas. Has become. Such a gas lighter is roughly divided into a piezoelectric ignition type lighter (a so-called piezo lighter) that uses a piezoelectric unit that generates a high voltage by hitting a piezoelectric element with a hitting mechanism and ignites by spark discharge, or a file of a firing stone. There is a file-type lighter (so-called flint-type lighter) that ignites with sparks at the time of rubbing, and a lid is covered on the top of the piezo lighter so that it can be opened and closed, and the piezoelectric unit is opened and closed by opening and closing the lid. There is a gas lighter with a lid that operates the. Further, in recent piezoelectric ignition type gas lighters, an internal combustion mechanism such as a combustion cylinder is built in the lighter body, and air and gas are mixed in the lighter body to perform a burner-like ignition and combustion. A wind-resistant gas lighter called a so-called internal combustion gas lighter has already been devised.

[0003] Among these gas lighters, especially in the above-mentioned piezoelectric ignition type gas lighter, the valve of the gas ejection nozzle is automatically opened by the pushing operation of the ignition operating element, and instantaneously. Since a spark discharge is generated and ignited, it is expected that children or the like operate mischievously, and furthermore, it is feared that it may cause an accident such as a fire or a burn. For this reason, various operation lock devices for a gas lighter having a stopper capable of arbitrarily preventing the ignition operation of the lighter have been proposed.

Conventionally, as an operation lock device for such a lighter, for example, as shown in FIG. 8, an ignition operator 5 engaged with a distal end of a gas ejection nozzle 6a whose distal end projects to the top of the gas lighter main body 2 is used. In a flint type gas lighter for ejecting gas from the gas ejection nozzle 6a by pressing the gas in the valve opening direction, the flint type gas lighter is rotatably supported below the ignition operation element 5 with respect to the ignition operation element 5,
At a certain position, it contacts the upper edge of the lighter main body 2 to prevent the ignition operating element 5 from descending. At another position, the contact with the upper edge of the lighter main body 2 is released and the ignition operating element 5 is released. 5
A slider piece (operation piece) 8 fitted into the fitting groove 4d that allows the slider piece 8 to descend, and a mounting shaft that is vertically installed below the ignition operation element 5 and that allows the slider piece 8 to be rotatably inserted. There is a lighter with a lock member which is provided with a stopper S, which is loosely fitted below the spring S to prevent the slider piece 8 from coming off (see Japanese Utility Model Application Laid-Open No. 54-441).
No. 76).

[0005] Further, as shown in FIG.
Case 1 detachably accommodated therein, a cover 5A that is openably and closably covered at the top of the case 1, a flange 5B protruding from a desired position of the cover 5A, A locking ring 5C for detachably locking the collar body 5B with the collar body 5B;
There is a safety device for an internal combustion gas lighter including an operation button 5D for releasing the engagement between the lid 5A and the outer case 1 (see Japanese Utility Model Laid-Open No. 2-54048).

[0006]

SUMMARY OF THE INVENTION However, among the conventional operation lock devices described above, the actual operation lock device is disclosed in Japanese Utility Model Application Laid-Open No. 54-4417.
In the gas lighter with a lock member disclosed in Japanese Patent Publication No. 6 (1994), since the free end side of the stopper S (specifically, the slider piece 8) as the lock member protrudes outward from the surface of the lighter body 2, For example, when such a lighter is put in a pocket, a bag or the like, an external impact or a fingertip put in casually in a series of operations may cause the stopper S (specifically, the slider piece 8) to move. It has a drawback that it easily rotates in the release direction by touching the protruding portion, and there is a problem that the locked state is released unexpectedly.

Further, such a stopper S is provided so that a mounting portion of the slider piece 8 formed in a ring shape is inserted into a mounting shaft vertically suspended below the ignition operating element 5 and a portion below the stopper is prevented by a spring. Therefore, even if the slider piece 8 of the stopper S is displaced to the locked state, the stopper S moves with a very small force applied in the releasing direction (horizontal direction). In addition, it has a disadvantage that it rotates more than necessary (180 degrees or more).

In addition, the fitting groove 4d for locking the stopper is exposed to the outside, and the engagement state of the stopper S (specifically, the slider piece 8) can be sensed from the outside. The appearance was impaired, and particularly the high-grade gas lighters reduced the commercial value.

On the other hand, in the safety device disclosed in the above-mentioned Japanese Utility Model Laid-Open Publication No. 2-54048, the flange 5B and the operation button 5D are connected to the cover 5A or the surface of the case 1 without necessity. The lighter has a drawback that irregularities appear on the outer peripheral surface of the lighter, and it becomes bulky when placed in a pocket or the like. Moreover, in such a safety device,
In order to prevent the lid 5A from opening unintentionally, a locking ring 5C for locking the flange 5B and the case 1 must be fixed, and each time the lid 5A is opened and closed. There was also a trouble that the hooking operation of the locking ring 5C had to be repeated.

[0010] Further, such an internal combustion type gas lighter has the advantage that it can be used without any problem even in a strong wind because the mixed gas produced by the jet jet is burned and ignited in a burner shape. As described above, since the flame is ignited and burned in the lighter body without swelling outward from the flame opening at the top end of the windshield, the lighter member near the combustion cylinder is heated to a considerable extent. In particular, in the case of the ignition operation element 5 which is directly touched by the finger of the hand, it is desirable that the ignition operation element 5 should be kept away from the combustion tube or the lighter main body 2 at least at the time of ignition.

The present invention has been made in view of such a conventional problem, and can be locked easily and securely without impairing the appearance of the lighter, and cannot be easily operated even by touching a finger or the like. In other words, an object of the present invention is to provide an operation lock device for a gas lighter which can surely prevent an easy unlocking of a stopper against an intention.
