Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention mainly relates to a safety device used in a flint-ignited disposable gas lighter.

(Prior Art) Conventionally, a flint-ignited disposable gas lighter has a file wheel exposed to the outside at the top of the lighter body, a flint is pressed against the underside of the file wheel, and the gas is inserted into the front side of the file wheel. The jet nozzle is protruded, and at the rear of the file wheel, an operation piece of a valve operating lever for operating the nozzle in the pull-out direction to open the valve is protruded, and the valve is operated by pressing the fingertip against the outer surface of the file wheel. By pulling down on the operating piece of the lever, the file wheel is rotated by the fingertip, scraping the flint and emitting sparks towards the nozzle side, and the operating piece is pushed down with the same fingertip, thereby Generally, a valve opens, gas is ejected from a nozzle, and is ignited by the spark.

Further, a file wheel is exposed at the top of the lighter body, and an operating piece of a valve operating lever for operating the valve of the gas jet nozzle in the opening direction is positioned adjacent to the ignition operation direction side of the file wheel, and
The outer surface of the operating piece of the valve operating lever is provided with a stepped portion facing in the operating direction of the operating piece, and the ignition operator is actuated via a stopper piece that is engageably provided at a position opposite to the stepped portion. There was a safety device on the gas lighter that prevented the push-in operation.
(Refer to Publication No. 44176 and Japanese Utility Model Application Publication No. 56-76227).

(Problems to be solved by the invention) Among these conventional disposable gas lighters, gas lighters without a stopper piece have a simple structure, can be provided at a low price, and are easy to use. However, since the ignition operation is performed by a continuous movement of one finger in one direction, in some cases even infants and children can operate it, and there is a risk of accidentally igniting the ignition and causing burns or fires. It is possible that this will happen.

On the other hand, in a safety device for a gas lighter that prevents the pushing operation of the ignition operator through a stopper piece (Japanese Utility Model Publication No. 54-44176), one end of the stopper piece (lock member) is connected to the operating piece. Since it protrudes outward beyond the rolling part, there is a problem that the lock state may be released unexpectedly.

For example, if you keep such a lighter in your pocket, etc., when you put your hand inside the pocket, your fingertips will touch the protrusion and easily turn in the release direction. had.

Moreover, such a stopper piece (lock member)
The stopper is formed in a ring shape and is rotatably assembled by simply inserting it into a shaft hanging below the operation piece (rolling part), so it cannot be released even if the stopper piece is moved to the locked position. It would move with the slightest force applied in any direction.

Furthermore, the lock mechanism has the drawback that the stopper piece must be biased upward by a spring to prevent such easy movement and to prevent the stopper piece from slipping off the shaft. Moreover, since the number of parts increases accordingly, it has not been possible to meet the need for an inexpensive disposable gas lighter (so-called 100 yen lighter) with a minimum number of parts.

The present invention was developed in view of these conventional problems and requests, and is a simple method that does not require a large number of parts.In other words, it is a simple method that does not require the number of parts. It is an object of the present invention to provide a safety device for a gas lighter which can easily and reliably maintain the locked state and prevent the stopper piece from being easily unlocked against the user's intention.

(Means for Solving the Problems) In view of the above-mentioned problems, the feature of the present invention is to provide a file wheel exposed at the top of the lighter body, and to achieve the initial objective. An operating piece of a valve operating lever for operating the valve of the gas ejection nozzle in the opening direction is positioned adjacent to the ignition operating direction, and an outer surface of the operating lever of the valve operating lever is opposite to the operating direction of the operating lever. In the gas lighter safety device, the gas lighter is provided with a stepped portion and prevents the pushing operation of the ignition operator via a stopper piece that is engageably or rotatably provided at a position opposite to the stepped portion, wherein the stopper piece is , comprising a support shaft protruding from both the upper and lower sides of the windshield end, and a hook formed by bending the other end inward, and
The support shaft of the stopper piece is inserted into the stopper support piece, which is formed by cutting out the side edge of the windshield and being bent inward, and through bearing holes provided in the top surface of the lighter body corresponding to the stopper support piece. The stopper piece, which is arranged in a locked state, is arranged in a position opposite to the stepped part and does not protrude from the surface of the lighter body, so that the hooking part of the stopper piece can be operated. A safety device for a gas lighter characterized by engaging and holding a lower part of the gas lighter.

(Function) In the present invention configured as described above, the stopper piece has a support shaft protruding from both the upper and lower sides of the windshield side end;
a stopper support piece comprising a hook formed by bending the other end inward, and formed by cutting out the side edge of the windshield and bending the stopper support piece inward; and a lighter corresponding to the stopper support piece. The support shaft of the stopper piece is rotatably supported through bearing holes provided in the upper surface of the main body, and the stopper piece disposed in a locked state is positioned opposite the stepped portion and the lighter body By arranging the stopper piece at a position that does not protrude from the surface thereof and engaging and holding the hook part of the stopper piece under the operation piece, the ignition operation of the lighter is prevented even if a downward force is applied to the operation piece. At the same time, the hooking part of the stopper piece is easily and reliably held under the step, so even if a small amount of force is applied to the stopper piece in the releasing direction, it will not come off easily. Since the piece does not protrude from the surface of the lighter body, it will not come off easily if touched by a finger or the like.

(Example) Next, an example of implementation of the present invention will be described with reference to the drawings.

A stopper support piece 17 is cut and molded inward on the upper edge of the stopper support piece 6, and the stopper piece 13 is inserted into a bearing hole 18 opened in the stopper support piece 17 and a bearing hole 19 formed on the upper surface of the lighter body 1. Both support shafts 14, 14 are rotatably fitted and supported.

The stopper piece 13 disposed in the locked state is disposed at a position opposite to the stepped portion 12 and at a position that does not protrude from the surface of the lighter body 1, so that the locking portion 13a of the stopper piece 13 can be attached to the operating piece. It is assembled so as to be able to engage and hold the lower part 11.

Therefore, the stopper piece 13 in such a locked state prevents the ignition operation of the lighter even if force in the downward direction is applied to the operation piece 11, and the stopper piece 13 can be easily placed under the stepped portion 12. Since it is held securely, it will not easily come off even if a small amount of force is applied to the stopper piece 13 in the releasing direction, and the stopper piece 13 does not protrude from the surface of the lighter body 1. So,
