Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a gas lighter operation lock device that disables the operator of a gas lighter having a piezoelectric ignition mechanism.

(Prior Art) Conventionally, as a gas lighter having a piezoelectric ignition mechanism, a piezoelectric unit containing a piezoelectric element and a striking mechanism is housed in the lighter body, and an operator that interlocks the operating part of the piezoelectric unit is housed in the lighter body. By pushing the operator into the lighter body, the on-off valve of the gas jet nozzle is operated in the opening direction, and the impact mechanism of the piezoelectric unit is activated.
There are widely available devices in which a high voltage is generated and gas ejected from a nozzle is ignited by a spark discharge.

(Problem to be solved by the invention) In a gas lighter with such a conventional piezoelectric ignition mechanism, the valve of the gas jet nozzle is automatically opened by the operation of the operator, and the spark for ignition is released. Since the device is ignited by the generation of electric discharge, there is a problem that children or the like may operate it by mistake, which could cause a fire or burns.

In view of these conventional problems, the present invention aims to provide an operation locking device for a gas lighter, which locks the operation of the operator as necessary to make the ignition operation impossible.

(Means for Solving the Problems) The gist of the present invention for solving the above-mentioned conventional problems is that an ignition operator is mounted on the top of the lighter body and reciprocated in the direction of pushing it into the lighter body. In the gas lighter, the piezoelectric unit is operated by the push-in operation of the ignition operator, the outer surface of the ignition operator is provided with a stepped portion facing in the pushing direction, and the stepped portion of the lighter body is The operation locking device for a gas lighter is provided with a stopper piece which is reciprocatably provided with a stopper piece whose tip faces the step part and prevents the ignition operator from being pushed in when the ignition operator is in an upright state at a facing position.

(Function) In this operation lock device, by raising the stopper piece and having the tip of the stopper piece face the lower part of the step of the ignition operator, the tip of the stopper piece comes into contact with the step part and the pushing operation of the ignition operator is blocked. In addition, by folding down the stopper piece, the ignition operator can be pushed in.

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

1 in the figure is a lighter body, and this lighter body 1 consists of a gas tank 2, a cap 3 that closes the opening of the gas tank 2, and an intermediate case 4 supported on the cap 3. , a piezoelectric unit 5 is inserted. Although not shown in the figure, the piezoelectric unit 5 has a built-in piezoelectric element and a striking mechanism for striking it, and a high potential difference is created between the terminals 6 and 7 by pushing in the upper end.

The piezoelectric unit 5 is housed in the lighter body 1 with its upper end protruding from the upper end of the intermediate case 4, and the ignition operator 8 is placed over the upper end of the piezoelectric unit 5.

A discharge electrode 9 connected to the terminal 6 is protruded from the front of the upper end of the ignition operator 8, and a protrusion 8a on the front surface of the upper end is brought into contact with the lower side of the windshield 10 to prevent it from coming off.

The windshield 10 is formed by press-molding a metal plate, and has a cut-out piece 10a cut upward and inward on the body of the windshield 10.
is engaged with a recess on the outer surface of the intermediate case 4 to prevent it from coming off.

Further, a gas jet nozzle 11 is protruded from the upper end of the lighter body 1 toward the flame port 10b of the windshield 10.
By operating the operating lever 12 in the drawing direction, the valve 13 is opened and gas is spouted out. The operating lever 12 is made of a conductive material, and by pushing in the ignition operator 8, the operating part of the piezoelectric unit 5 is pushed down and the terminal 7 comes into contact with the operating lever 12, which causes the lever 12 to contact the valve 13.
After the nozzle is operated in the opening direction, a high voltage is generated, a spark discharge is made between the nozzle 11 and the discharge electrode 9, and the nozzle is ignited.

A flange portion 8a is formed at the upper end of the outer surface of the ignition operator 8, and a lower peripheral edge of the flange portion 8a forms a downward step portion 14. A stopper piece 15, which will be described later, is provided at a position opposite to this step portion 14.

The stopper piece 15 constitutes the lighter body 1. Recess 4a formed in the upper edge of intermediate case 4
One end of the stopper piece 15 is attached to the inside with a pin 16 so that it can be accessed freely, and by standing this stopper piece 15 upright as shown in FIG. Even if a pushing force is applied to the operator 8, the tip of the stopper piece 15 comes into contact with the stepped portion 14, thereby preventing the ignition operation.

(Effect of the invention) The present invention is constructed as described above, and includes a stepped portion formed on the outer surface of the ignition operator, and a stopper piece that faces the stepped portion in an upright state and is removably provided on the lighter body. The ignition operator is locked by standing the piece upright and facing the stepped part of the ignition operator, which has a simple structure that prevents accidental ignition by children, etc., and increases safety. It is something that
