Abstract

PURPOSE:To prevent heat conduction to a strut bearing a file and a file wheel and to keep a flame stable, by providing a heat insulating wall on a component forming a windshield. CONSTITUTION:As for this gas lighter, a notch is provided on positions of side wall surfaces 1a, 1a of a windshield 1 opposing to each other by leaving parts of the surfaces unnotches and heat insulating walls 1b, 1b are formed by bending the notched pArts at about right angle toward the inside of the windshield. As a part of a strut 5 formed of plastics which is apt to be affected most by a flame is interrupted completly from the flame by the heat insulating walls 1b, 1b when gas erupting through a nozzle 6 is ignited by a flint by making a file wheel 2 turn by a file auxiliary wheel 3, a matter that the strut 5 is ignited and the above part is fused through heat does not happen even if an ignition period is long to some extent. A hole formed acts as a ventilating opening and keeps the flame stable further.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a gas lighter, and particularly to a disposable, inexpensive gas lighter.

Inexpensive disposable gas lighters are constructed so that they can be used with a safe and always stable flame until all the gas stored in the gas tank is used up, and the number of parts is reduced to make them smaller and lighter. Various improvements have been made to reduce costs.

As a result, it is now possible to obtain a stable flame (1) at all times, as well as to be able to reliably adjust the flame, as well as various lightweight and excellent designs have been developed.

However, this type of gas lighter has a problem in that when it is ignited, heat is easily conducted to the support that rotatably supports the file and the file wheel. In particular, since the above-mentioned supports are usually made of synthetic resin such as plastic, if the ignition time is too long, the above-mentioned parts may catch fire, or the above-mentioned parts may be melted and deformed by the heat. There were problems such as the file wheel not being able to be rotated properly, making it difficult to ignite.

Therefore, it is very dangerous for the above-mentioned support section to catch fire or to be melted and deformed by the heat during ignition.In particular, if the above-mentioned support section is deformed, the ignition device will be damaged. The function of the gas lighter deteriorates, and even if there is sufficient gas left in the sheet metal gas tank, it cannot be used, and a new gas lighter must be purchased, which is also uneconomical.

(2) In order to solve this problem, gas lighters have been proposed in which the struts are made of metal or heat-resistant materials, but these have the problems of increased weight and cost.

The present invention was made from the viewpoint of soft soil, and its purpose is to prevent the main body or support portion of the gas lighter from catching fire when ignited, and to completely eliminate the gas in the gas tank. The present invention aims to provide a gas lighter that can ignite reliably, is easy to manufacture, and can keep costs low.

The above purpose is to rotate the file wheel of the ignition device by making approximately U-shaped cuts in opposing parts of both side wall surfaces of the member forming the windshield and bending the cut parts into the windshield. This is achieved by forming an insulating wall that shields the movably supported strut portion from flames.

In addition, the approximate U-shape here refers to a complete U-shape, a semicircle, a C-shape, a U-shape, a V-shape, a single-shape, a triangle, etc.
It refers to all shapes that can achieve the same effects as the present invention (3).

Hereinafter, the details of the present invention will be specifically explained with reference to the drawings.

FIG. 1 is a partially cutaway side view of a gas lighter according to the present invention, FIG. 2 is a top view thereof, and FIG. 3 is an enlarged view of a windshield portion thereof.

In Figures 1, 2, and 3, 1 is the windshield, 1as1a is the side wall of the windshield 1, and lb and Ib are the side walls 1a and 1a of the windshield 1, with a portion left in the opposing parts, respectively. 1c is a ventilation hole, 2 is a file wheel, 3 is a file auxiliary car, 4 is a file shaft, and 5 is a support that holds the file shaft 4. , 6 is a nozzle, 7 is a nozzle adjustment ring, 8 is a nozzle adjustment lever that is attached to the nozzle adjustment ring 7 and rotates the nozzle adjustment ring 7 to adjust the length of the flame, 9 is a lever that moves the nozzle 6 up and down. This is a nozzle lift lever that can be adjusted.

Therefore, in the gas lighter according to the present invention, a cut is made leaving a part (4) at the opposing positions of the side wall surfaces 1a and 1a of the windshield 1, and then the above part is inserted into the windshield. The insulation walls 1b, lb are formed by bending at a substantially right angle.

Therefore, when the file wheel 2 is rotated by the file auxiliary vehicle 3 and the gas ejected from the nozzle 6 is ignited with a flint, the support column 5 made of plastic is most susceptible to flames.
The part indicated by is the heat insulating wall 1b.

1b completely blocks the flame, so even if the ignition time is a little long, the pillar 5 will not catch fire, and
The above parts will not melt due to heat.

Furthermore, the heat insulating walls 1b, lb formed on the side wall surface 1as la of the windshield 1 protect the support column 5 from heat as described above, and the holes formed act as ventilation holes.

That is, sufficient air necessary for combustion can be supplied to the insulating wall lb,
Since the air is supplied from the hole in the portion where the lb is formed and the supply path of the supplied air matches the combustion direction of the flame of the ignited gas lighter, the flame can be kept even more stable.

(5) Since the present invention is constructed like soft soil, when using the gas lighter according to the present invention, heat conduction to the file and the pillar that rotatably supports the file wheel, which is most susceptible to the influence of heat during ignition, etc. It is possible to prevent this and keep the flame extremely stable.

Note that the present invention is not limited to the examples of soft soil. That is, for example, in this embodiment, a cut is made leaving a part of the side wall surface of the windshield facing each other, and then the said part is bent at a substantially right angle into the windshield to form a heat insulating wall. However, it is also possible to form a heat insulating wall by making a notch in the side wall surface of the member forming the heat insulating wall and making the sides of the cut bulge into the windshield. Further, in this embodiment, the gas lighter is of a type in which ignition is performed by rotating a file wheel, but it can also be used for a gas lighter equipped with an ignition mechanism composed of a piezoelectric element, etc. Furthermore, it can also be used in a gas lighter having a cartridge type gas tank. In addition, the shapes of the windshield and the heat insulating wall, the formation position of the above heat insulating wall, etc. can be freely changed within the scope of the purpose of (6) of the present invention, and the present invention does not encompass all of them. be.
