Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a gas lighter that prevents infants, children, etc. from easily igniting the gas lighter, thereby preventing burn injuries caused by accidental ignition.

(Prior Art) Conventionally, as disclosed in Japanese Utility Model Application No. 57-30562, a file wheel is rotatably supported on the upper half of the U-shaped side as an ignition device for a gas lighter, and a A supporting member cylinder, in which a lighter stone and a coil spring are sequentially fitted into a cylinder forming one half, is fitted into a recess provided on the upper side of the main body in a slidable and resilient manner, and the supporting member that the file wheel has. Both ends of the shaft are movably fitted into elliptical holes in two opposing support walls with recessed parts, and a notch provided in the center is movable into the cylindrical body of the support member. A step is provided on the right half of the operating lever that opens and closes the fitted nozzle to form a bulge for finger rest, and the upper left corner and part of the U-shaped part that forms the upper half of the support member. A structure was proposed in which the parts could be removably engaged with a slight gap between them.

(Problems to be Solved by the Invention) However, since the conventional ignition device described above opens and closes the valve via an operating lever by moving the support member up and down, it is not designed to prevent rotation of the file wheel. If the file wheel is rotated as it is, it will immediately ignite, so there is a problem that infants and children may accidentally cause burns by rotating the file wheel and igniting it. Since the structure also moves the support members that support each member of the spring, there is a problem that the structure of the parts is complicated and it takes time and effort to assemble, making it difficult to manufacture at a low cost.

This invention attempts to solve the above-mentioned conventional problems, and in order to rotate the file, it is possible to ignite the file not only by the action of simply giving rotation to the file, but also by the combined action of pushing and rotating the file. The purpose of this invention is to provide a gas lighter equipped with a safety mechanism.

(Means for Solving the Problems) A gas lighter according to the present invention for achieving the above-mentioned purpose is a gas lighter equipped with a nozzle mechanism and an ignition mechanism on the upper part, and the file bearing holes 1a and 1b are made into oval shapes. The file shafts 2a and 2b are loosely fitted in the file bearing holes 1a and 1b so as to be movable in the vertical direction, thereby enabling the file 2 to rotate. The spring 3 is pushed upward, and the spring 3 has an elastic force that can contact and lock the file 2 to the end of the windshield 4 and press down the file 2 to allow the file 2 to rotate. The structure is characterized in that it includes a contact locking part for the file 2.

(Function) When using the gas lighter of the present invention, even if you simply try to rotate the file 2 like a normal lighter to perform the ignition operation, the file 2 will move against the outer peripheral surface of the file 2 due to the repulsive force of the spring 3. Since it is locked with the contact locking part of the windshield 4, it does not rotate.If you try to give it rotation and generate sparks by friction with the flint 5, you can move the file 2 to the flint 5. The ignition is caused by the combined action of pushing in the direction of the spring 3 to release the contact between the outer peripheral surface of the file 2 and the windshield 4, and then applying rotation. 2 moves upward, and its outer circumferential surface is locked to the contact locking portion of the windshield 4, thereby preventing rotation.

(Embodiment) Next, an embodiment of the gas lighter according to the present invention will be described based on FIGS. 1 to 4 of the drawings. The intermediate case 1 is attached to the fuel case 6, which is equipped with a nozzle mechanism and an ignition mechanism on the upper part. The intermediate case 1 is provided with a cylinder with a bottom that accommodates a flint 5 and a spring 3, and the file 2 is positioned above the flint 5, and both sides of the file 2 are attached to a file shaft 2a, 2b
Bearing holes 1a and 1b are provided in the case 1 in correspondence with the file shafts 2a and 2b.

Because the flint 5 is urged toward the file 2 by the repulsive force of the spring 3, the file shafts 2a, 2b are pushed up toward the windshield 4 along the file bearing holes 1a, 1b, and the outer surface of the file is configured to engage with the contact engagement portion formed on the end face of the windshield 4.

Note that in order to contact and lock the end surface of the windshield 4, it is not limited to the outer circumferential surface of the file 2 as described above, but as shown in FIG. Attach the auxiliary vehicles 2'c and 2'd formed by the auxiliary vehicle 2'
Alternatively, the outer peripheral surface of 2'd may be brought into contact with the end surface of the windshield 4.

Further, the file shafts 2'a and 2'b of the file 2' may be provided on the auxiliary wheels 2'c and 2'd.

Furthermore, in this embodiment, the flint 5 spring 3
Although the bottomed cylinder housing the cylinder and the bearing holes 1a and 1b of the file shafts 2a and 2b are provided in an intermediate case that is attached to the fuel case, the intermediate case is not used and the bearing holes 1a and 1b are integrated with the main body container. may be configured.

(Effect of the invention) Since the gas lighter according to the invention is constructed as described above, when performing the ignition operation with this gas lighter, a complex action of pushing down the file and then rotating it is required, so it is difficult to do it like a child. It cannot be easily ignited by a weak force like the conventional one, and it can be easily operated by an adult who is originally intended for igniting a cigarette. It can help reduce burns, fire accidents, etc. associated with operation.

Furthermore, even when the file is stored in clothing or left unattended, the force of the spring keeps the file in contact with the windshield, so the file is locked against rotation and is protected from unexpected friction. It also has the effect of preventing accidental ignition.

Furthermore, there are lighters on the market that are equipped with metal caps and safety lock mechanisms for safety.
Both of them are structurally expensive, but the present invention makes it possible to provide lighters with high safety at low cost, without significantly changing the current structure of lighters, especially disposable lighters.
