Description

  In the gas lighter, by providing a clip on the operation button operated at the time of ignition, it is possible to perform safe ignition not only in the vertical direction but also in any posture, and the lighter body can be attached to the clothes. The present invention relates to a gas lighter configured to be held in a pocket.

  Normally, a gas lighter is used exclusively for cigarette ignition, and is held by holding the lighter body in a vertical direction in a hand and pressing an operation button downward with a thumb to ignite.

  In addition, the fuel tank and case are molded of synthetic resin for light weight and miniaturization so that it is convenient to carry. The fuel tank only needs to have a volume necessary for ignition for a certain period of time. Is considered disposable.

As disclosed in Patent Documents 1 and 2 below, since the lighter body is a relatively small object, a clip is attached to the body so that it is not confused with other objects in the pocket or bag of the clothes. Lighters that have been clipped and held in pockets or bags have been proposed.
Utility Model Registration No. 3093584 Japanese Patent Laid-Open No. 10-30820

  However, in the conventional gas lighter, when ignited, the lighter body is held vertically and held in the hand, and the operation button is pushed downward with the thumb to ignite, so the cigarette is mainly ignited. When igniting an object that cannot be ignited from below, it is necessary to hold the ignited object sideways or hold the lighter sideways to perform the ignition operation, making it difficult to ignite. There was a risk of burns.

  On the other hand, a lighter with a clip attached to the main body can be hooked and held in a pocket of clothes, but the clip itself has only a function as a holding member, and the necessity to attach it was not felt.

  Therefore, the present invention devised the operation button to not only ignite by holding the gas lighter main body in the vertical direction, but also enables safe ignition even if the gas lighter main body is in an arbitrary posture, It was conceived to provide a gas lighter having a function as a clip for holding the gas lighter main body in a pocket of clothes.

  A gas lighter according to the present invention includes a fuel tank that stores liquefied fuel gas, an ejection nozzle that ejects the fuel gas, a valve that controls opening and closing of the nozzle, a piezoelectric device that ignites the fuel gas, and In a lighter comprising an opening / closing control and an operation button for operating the piezoelectric device to generate a flame, a clip extending in the longitudinal direction from the top of the operation button along the lighter body is formed, and can be operated by the clip It is what.

  The gas lighter using the operation button of the present invention can be safely ignited even if the lighter body is in an arbitrary posture, and can be used as a substitute for an ignition rod.

  Further, the lighter can be held with the edge of the pocket of the clothes sandwiched between the lighter body and the clip.

  The present invention can be easily applied to any gas lighter having a simple structure and an exposed operation button.

  FIG. 1 (a) is a perspective view showing a state in which an operation button in which the clip of the present invention is integrated or integrated by bonding or the like is attached to the gas lighter body, and FIG. 1 (b) shows the clip of the present invention. It is a perspective view which shows the operation button integrally molded.

  The gas lighter according to the present invention includes a fuel tank 4 made of a synthetic resin, in which liquefied fuel gas is stored, an oval cross section, an intermediate case 5 that seals the opening of the fuel tank 4, a crater 61, and an air hole. A horseshoe-shaped metal cap 6 having a hook portion 63 with a perforated 64, an operation button 2 integrally formed with the clip 3, and an adjustment ring 62 for adjusting the height of the flame are provided.

  A synthetic resin such as ABS or polyacetal is suitable for the material of the operation button 2 and the clip 3.

  The metal cap 6 is fitted into the top of the intermediate case 5 and is fixed to the intermediate case 5 by a hook portion 63. Further, the operation button 2 is inserted into the intermediate case 5 so as to slide up and down. That is, the intermediate case 5 serves as a sliding guide 51 (see FIG. 2) when the operation button 2 is operated.

  The operation button 2 includes a top surface 21 that is pushed down with the thumb when the lighter is held in the vertical direction and a sliding portion 22 that slides in the intermediate case 5. The cross section has the same cross sectional shape as the sliding guide 51 formed in the intermediate case 5.

  In addition to this, an ejection nozzle for ejecting a gas (not shown), a valve for controlling the opening and closing of the nozzle, a piezoelectric device for generating a high voltage pulse voltage, and the like are provided. At the same time, the gas is ignited by a high voltage pulse generated by operating the piezoelectric device.

  The operation button 2 is integrally formed with a clip 3. The clip 3 has a narrow upper portion 31, a flat and wide intermediate portion 32, and a bulge that is thickened so that the thumb does not slip. The width of the narrow upper portion 31 is limited by the size of the top surface 21 of the operation button 2, and the length of the upper portion 31 is a metal cap at the wide intermediate portion 32. The length is set so as not to block the six air holes 64. The size of the wide intermediate portion 32 and the bulging portion 33 may be configured so as to be easily operated according to the thickness of the thumb.

  Instead of the bulging portion 33 formed below the flat portion 32, a plurality of ridges or grooves may be formed on the surface to prevent slipping.

  When the operation button 2 is fitted into the intermediate case 5, the clip 3 is positioned in a state extending in the longitudinal direction along the lighter body 1. At this time, in order to support the clip 3 with a gap from the gas lighter main body 1, the tip of the upper portion 31 is formed in an inverted L shape. Since a gap 34 (see FIG. 2B) is formed between the gas lighter body 1 and the clip 3, the clip 3 can hold the lighter in a pocket or bag of clothes.

  Next, the ignition operation of the lighter assembled in this way will be described with reference to FIG.

  Hold the lighter body 1 with your thumb on the clip 3. When the clip 3 is pulled down against the elasticity of the hammer spring of the built-in piezoelectric device with the thumb from the stopped state shown in the front view of FIG. 2A and the side view of FIG. 2B, FIG. As shown, the operation button 2 also moves down along the sliding guide 51 in the intermediate case 5 in conjunction with the clip 3, so that the gas ejected can be ignited by the operation of the internal piezoelectric device.

  When the thumb is released from the clip 3 after ignition, the operation button 2 is pushed back by the elasticity of the return spring, the operation button 2 and the clip 3 are returned to the initial positions, and a series of ignition operations is completed.

  As described above, when the clip 3 is used for ignition, since the thumb is separated from the flame after ignition, the crater portion 61 and the thumb on the clip 3 are separated even if the lighter body 1 is turned sideways or tilted downward. It can be used for various purposes, such as igniting the fire type (charcoal) of the incense stand.

  Further, like the conventional gas lighter, the lighter body 1 is held in the hand with the thumb placed on the top surface 21 of the operation button 2. When the top surface 21 of the operation button 2 is pushed down against the elasticity of the hammer spring of the built-in piezoelectric device with the thumb from the stopped state shown in FIGS. 2 (a) and 2 (b), FIG. As shown, the operation button 2 descends along the slide guide 51 in the intermediate case 5 and the internal piezoelectric device is activated to ignite the gas ejected.

The perspective view (a) which shows the state which attached the operation button which integrally formed the clip of this invention to the gas lighter, the perspective view (b) which shows the operation button which formed the clip integrally, It is a figure explaining operation | movement of the operation button which integrally formed the clip of this invention, Comprising: The front view (a) of the gas lighter main body before operation, the right view (b) of the gas lighter main body before operation, the gas after operation It is a front view (c) of a writer main body.
