BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable gas lantern that is used as an illumination light source by bringing it to a mountaineering or camping site, and in particular, a gas lantern in which a gas outlet pipe is bent into a substantially 7-shape in a space inside a squirt. The mantle support structure in.

[0002]

2. Description of the Related Art A portable gas lantern has a so-called gooseneck type gas lantern in which a gas outlet pipe is formed into a substantially 7-shape inside a squirt and a mantle is suspended and supported at the tip of the gas outlet pipe. There is a type of gas lantern in which a gas outlet pipe is erected straight up in the space inside the squirt and the mantle is supported on the protruding upper end.

[0003]

In a gas lantern of the type in which the mantle is supported on the upper end of the gas lead-out pipe formed by standing up, the mantle can be supported only by inserting the mantle at the tip of the gas lead-out pipe. However, in this case, there is a problem that the amount of light is lower than that of the gooseneck type because the tip of the gas outlet tube is located inside the mantle so as to penetrate therethrough.

On the other hand, the gooseneck type gas lantern has the advantage that a large amount of light can be obtained, but it has a structure in which the mantle is tied to the tip of the gas outlet pipe with a string. However, since the outer diameter of the tip of the gas outlet pipe is about 15 to 20 mm, the work of binding with a string is a fine work, and there is a problem of poor workability. The present invention has been made paying attention to such a point, and provides a mantle fixing structure capable of easily fixing the mantle to the tip of the gas outlet pipe while obtaining a large amount of light. Is intended.

[0005]

In order to achieve the above-mentioned object, the present invention provides a linear body formed in a continuous corrugation in a plane and formed in an annular shape with the corrugations positioned in the radial direction. , The annular shaped linear body is formed in a state where both end portions of the linear body are vertically overlapped with each other, and both end portions of the linear body are respectively projected upward and operation knobs are formed at the projecting end portions to fix the mantle. The mantle fixing tool is characterized in that the mantle fitted onto the tip of the gas lead-out pipe is clamped and fixed by the mantle fixing tool.

[0006]

According to the present invention, the linear body formed into a continuous wave shape in a plane is formed into an annular shape with the wave shape being positioned in the radial direction, and the annular shaped linear object is It is formed in a state of vertically overlapping, and both ends of this linear body are projected upward, and operation knobs are formed at the protruding ends to form a mantle fixing tool, so that both operation knobs are gripped. As a result, the diameter of the mantle fixing tool is expanded, and the mantle fixing tool is displaced in the diameter reducing direction by releasing the operation knob. In addition, since this mantle fixing tool is composed of a linear material formed in a continuous corrugated shape, the mantle fixing tool comes into contact with the mantle at the outer end of the trough of each corrugation, and the mantle and the mantle fixing tool are Contact is point contact. As a result, even if the mantle contracts when it is baked after setting the mantle, the filaments of the mantle will not be cut.

FIG. 1 is a vertical cross-sectional view of a main part taken out, FIG. 2 is a schematic perspective view of the main part of a gas lantern, FIG. 3 is a plan view of a mantle fixing tool, and FIG. IV- in Figure 1
IV line sectional drawing, FIG. 5 is the VV line sectional view of FIG. This gas lantern includes a gas flow rate adjusting valve (2) screwed onto the upper surface of the gas cartridge (1), a bottom wall member (3) fixed to the upper surface of the gas flow rate adjusting valve (2), and the bottom wall member. The bottom wall member that is connected to the upper surface of the gas flow rate control valve (2) while penetrating (3)
(3) The gas outlet pipe (4) standing upright, the mantle (5) attached to the tip of the gas outlet pipe (4), and the glass surrounding the gas outlet pipe (4) and the mantle (5) Ascidian (6) and this ascidian
The umbrella plate (not shown) arranged so as to cover the upper opening of (6).

The squirts (6) are mounted so as to be fitted inside the rising peripheral wall portion of the outer peripheral edge of the bottom wall member (3) and received by the upper surface of the bottom wall member (3). Further, the umbrella plate is detachably attached and fixed to the upper end portion of the connecting rod (7) extending upward from the rising peripheral wall portion of the bottom wall member (3). A lantern hanging handle (not shown) formed by bending a wire rod is detachably attached to the upper end portion of the connecting rod (7). The hanging handle also serves as a connecting fixture for the umbrella plate and the connecting rod (7).

The combustion part of the lantern is composed of a gas outlet pipe (4) bent into a substantially 7-shape and a mantle (5) mounted downward at the tip of the gas outlet pipe (4). The mantle (5) is fixed to the tip of the gas outlet pipe (4) by a mantle fixing tool (8).

The mantle fixing member (8) is formed by forming a metal body (9) formed in a continuous wave shape in a plane into an annular shape with the wave shape being located in the radial direction, and forming the annular metal wire. body
(9) so that both ends of the metal wire (9) are wrapped vertically over a certain length, and both ends of the metal wire (9) are continuously extended in the radial direction of the annular body and then bent upward, and the upper end operation knob (10 ) Is formed. As a result, the metal wire
Since the mantle fixing tool (8) itself acts as an elastic material by the elastic deformation force generated by forming the (9) in a continuous corrugated form, the mantle fixing tool (8) discharges the gas from the mantle fixing tool (8). It will be fixed to the tip of the tube (4).

A mantle mounting procedure using the mantle fixing tool (8) having such a structure will be described. First, the mantle
The upper end opening of (5) is inserted into the mantle fixing tool (8), and the upper opening of the mantle (5) is pushed open to be arranged along the inner peripheral surface of the mantle fixing tool (8). Then, by manipulating the operation knob (10) of the mantle fixing tool (8) in a direction in which both the knobs (10) approach each other, the mantle fixing tool (8) is expanded with the inner diameter of the mantle fixing tool (8) being expanded. The mantle (5) and the mantle (5) are fitted onto the tip of the gas outlet pipe (4), and the operating knob (10) is released. Then, the mantle fixing tool (8) is deformed by its own elastic force so that its inner diameter is reduced, and the mantle fixing tool is
The mantle (5) is clamped and fixed between (8) and the gas outlet pipe (4).

At this time, since the mantle fixing tool (8) is constituted by a continuous wave type linear body, this mantle fixing tool (8) is formed on the mantle (5) at the outer surface of the corrugated valley portion. The contact area between the mantle fixing tool (8) and the mantle (5) is reduced, and the contact resistance at the time of mantle contraction deformation when the mantle (5) is air-baked is reduced. , The mantle (5) will not be damaged.

In the above embodiment, the metal wire (9) is bent into a continuous corrugation to form the mantle fixing tool (8). However, a linear body formed of an elastic ceramic material is formed into a continuous corrugation. Good.

[0014]

According to the present invention, the mantle fixing device is formed by forming the continuous band-shaped linear member into the annular shape with the corrugations located in the radial direction to form the mantle fixing device. Insert the upper opening of the mantle into the inside of the mantle, and with the operation knob of the mantle fixing tool pinched, and by fitting the mantle fixing tool and the mantle onto the gas outlet pipe, just release the operating knob of the mantle fixing tool. Since the mantle can be firmly held at the tip of the gas outlet pipe, the mantle can be easily attached to the gas outlet pipe.

Further, since the mantle fixing tool is formed of a continuous corrugated linear body, the mantle and the mantle fixing tool are in point contact with each other, and the contact area between the mantle and the mantle fixing tool is small. Even if the mantle contracts during air baking, the contraction of the mantle does not hinder the contraction, and it is possible to prevent damage to the mantle during mantle baking.
