 The safety button placed on the upper part of the lighter body is pressed against the nozzle side of the fuel supply means for ejecting the fuel gas, and the tip of the safety button and the gas lever are engaged. The gas lever is moved upward by the operation of the ignition means, and the safety button and the nozzle are also moved upward together therewith to ignite the ejected fuel gas.

[0010]

1 to 4, a gas lighter 1 with a safety device of the present invention shown in FIGS. 1 to 4 uses a lighter body 2 in which a fuel gas is stored, a fuel supply means 4 having a nozzle 3 for ejecting the fuel gas, A safety button 5 for operating the nozzle 3 sometimes, a gas lever 6 for engaging the safety button 5, and an ignition means 7.

The lighter body 2 has a rectangular parallelepiped shape formed of synthetic resin, and a fuel gas such as butane gas is stored therein. A known fuel supply means 4 (partially shown in the drawing) for controlling the ejection amount of the stored fuel gas is disposed inside the lighter body 2, and the nozzle 3 provided in the fuel supply means 4 is provided with a lighter. It protrudes from the upper part of the main body 2. Further, a ripper 10 to which a lighter stone 9 urged by a spring 8 is brought into pressure contact is arranged in a central portion of an upper portion of the lighter main body 2, and a gas lever 6 is mounted on one end thereof. The gas lever 6 is placed laterally along the upper surface of the lighter body 2, and a push-down portion 11 is formed above one end of the lighter body 2. A spring 12 having one end embedded in the lighter body is formed below the push-down portion 11. It has been reduced. The other end of the gas lever 6 extends in the vicinity of the above-mentioned fuel supply means 4, and a step portion 13 is formed above the end portion.

Further, a safety button 5 is arranged at the other end of the upper portion of the lighter body 2. The safety button 5 has an inverted L-shaped cross section, and one end of the safety button 5 projects slightly outside the lighter body 2, and a spring 15 is formed between the safety button 5 and the column 14 extending upward from the lighter body 2. The safety button 5 is contracted and constantly pushes the safety button 5 outward by the urging force of the spring 15. Further, a stopper 16 is formed on the lower surface of the safety button 5 at a substantially central portion so as to be in contact with the side surface of the column 14 and directed downward. At the other end of the safety button 5, a U-shaped groove 18 which is loosely fitted in the neck portion 17 of the nozzle 3 is defined (see FIG. 4), and the end portion is formed above the other end of the gas lever 6. It is located above and separated from the stepped portion 13.

Reference numeral 19 is a windshield. The operation of the safety device lighter 1 having the above-described configuration will be described in detail.

When the safety button 5 is not directed toward the lighter body 2 and is not pressed, even if the pressing portion 11 of the gas lever 6 is pressed while rotating the file wheel 10 with the thumb, the file stone 9 and the file wheel 10 come into contact with each other. However, since the other end of the gas lever 6 is not engaged with the safety button 5 fitted to the nozzle 3, the nozzle 3 cannot be raised and the gas lighter 1 is ignited. Never. Therefore, even if a person who does not know how to use it properly operates the gas lighter 1, it does not ignite and is safe.

Next, when it is desired to use the gas lighter 1, first, one end of the safety button 5 is pressed against the lighter body 2 against the biasing force of the spring 15. Then, the neck portion 17 of the nozzle 3 fitted to the tip of the U-shaped groove 18 at the other end of the safety button 5 slides in the groove 18 to reach the end of the groove 18, and at the other end of the safety button 5. Engage on the stepped portion 13 formed on the gas lever 6 (see FIG. 2). When the rasp wheel 10 is rotated while pressing the safety button 5 to press down the pressing portion 11 of the gas lever 6, the pressing portion 11 moves downward against the biasing force of the spring 12. Then, the other end of the gas lever 6 is lifted, the engaged safety button 5 is also lifted, and the nozzle 3 is also lifted upward. The flow path of the fuel gas is opened, the fuel gas is ejected from the nozzle 3, and the spark generated by the contact between the rasp stone 9 and the grinding wheel 10 is ignited (see FIG. 3).

When the thumb is released from the push-down portion 11 of the gas lever 6 while pressing the safety button 5, the push-down portion 11 returns to the initial state by the elastic force of the spring 12, and the safety button 5 and the nozzle 3 are released. Also descends and closes the fuel gas passage.

Next, when the hand is released from the safety button 5 and the pressing is stopped, the safety button 5 is directed toward the outside of the lighter body 2 by the elastic force of the spring 15 and moves until the column 14 and the stopper 16 come into contact with each other. .. Therefore, even if the safety button 5 and the gas lever 6 are separated from each other and the ripper 10 is rotated to generate a spark, ignition is not performed.

The lighter with safety device 30 shown in FIGS. 5 to 7 is another embodiment, and the same components as those in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

A U-shaped groove (not shown) is defined at the tip of the gas lever 31 mounted on the lighter body 2, and the small diameter portion 32 of the nozzle 3 is loosely fitted in the groove. At the end of the lighter body 2, a safety button 33 having a flat surface on the lighter side and a semi-cylindrical cross-section with the other side bulging is supported and attached to a hinge 34.

A leaf spring 36, one end of which is embedded in the recess 35 of the safety button 33 and the other end of which is embedded in the lighter body 2, is provided in a recess 35 defined on the inner surface of the lower end of the safety button 33. The button 33 is constantly operated in the direction of separating it from the lighter body 2. In addition, an auxiliary rod 38 extending in the direction of the nozzle 3 is provided in the recess 37 defined on the inner surface of the upper portion of the safety button 33. A spring 39 is contracted at one end of the auxiliary rod 38 and pressed against the lower surface of the recess 37, and the other end is placed on the tip of the gas lever 31 and further has a defined U-shape. Groove 40 faces the nozzle 3.

The operation of the safety device lighter 30 having the above-described configuration will be described. When the safety button 33 is not pressed in the direction of the lighter body 2, the state shown in FIG. 5, that is, the groove 40 of the auxiliary rod 38 does not fit into the nozzle 3, so the ripper 10 is rotated to generate a spark. However, since the fuel gas is not ejected from the nozzle 3, it cannot be ignited.

Next, when using the gas lighter, the safety button 33 is pressed toward the lighter body 2. Then, the auxiliary rod 38 disposed in the recess 37 also slides on the tip portion of the gas lever 31, and the groove 40 of the auxiliary rod 38 is fitted into the nozzle 3 (see FIG. 6). Next, when the rasp wheel 10 is rotated with the thumb while pressing the safety button 33 and the gas lever 31 is pressed down while generating a spark, the tip of the gas lever 31 is lifted upward, and the auxiliary rod 38 that is engaged is also lifted. They can be lifted together to open the nozzle 3 and ignite the fuel gas (see Figure 7).

When the safety button 33 is released from the pressure, it is separated from the lighter main body 2 by the elastic force of the leaf spring 36, and the auxiliary rod 38 is also removed from the nozzle 3. Further, the auxiliary rod 38 is pressed against the recess 37 by the elastic force of the spring 38.

Although it has been described that a file and a rasp are used as the ignition means, an electronic device may be used.
