Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable stove that uses a cassette cylinder filled with liquefied butane or the like as fuel. The present invention also relates to a portable gas stove that can be folded compactly and is convenient to carry.

[0002]

2. Description of the Related Art Conventionally, there has been no portable gas stove using gas as a fuel.

[0003] One of the reasons is that when compact,
This is a problem that it is difficult to shield the lower table and the like during use.

[0004] At the end of a burner or a stove using a cassette cylinder filled with liquefied butane or the like as a fuel, a mounting cap is provided for mounting the cassette cylinder. Since the mounting cap provided on such a device is covered by a ring provided on the concave end face of the head of the cassette cylinder, the size of the mounting cap is larger than the ring of the head of the cassette cylinder. For this reason, it has been said that a compact portable stove having a thickness smaller than the diameter of the mounting cap cannot be manufactured.

Therefore, the present invention is much thinner than a conventional portable gas stove, can be easily stored in a pocket, and, when used, shuts off heat downward and reduces the temperature of the table. The aim is to obtain a portable gas stove with excellent safety that does not scorch.

[0006]

A portable gas stove according to the present invention is provided with a rectangular metal housing case composed of a pair of left and right boxes which are opened in a V-shape by a hinge, and is detachable from the housing case. The stove includes a stove body housed in a housing case and legs for standing the left and right boxes in a V-shaped open state.

When the stove body is attached to the left and right boxes opened in a V-shape, the left and right boxes serve as heat shield plates and reflect heat upward, so that the heat efficiency is good. In addition, since a pot or the like can be placed on the upper side of the opened V-shaped box as it is, there is no need to separately prepare a goto or the like, and the size of the portable gas stove can be made compact.

[0008] The left and right boxes opened in a V-shape function as windshields.

Further, a portable gas stove having a smaller thickness can be obtained by employing the following structure of the cassette cylinder mounting device installed at the end of the stove body.

That is, the cassette cylinder mounting device is configured such that the opening cylinder that covers the opening valve on the head of the cassette cylinder and the outer surface of the mounting ring on the head of the cassette cylinder are changed from a straight line to a cross shape. It is composed of a pair of flat-shaped arm members that are rotatably combined with each other at a central portion so as to open. The one arm member is provided at the center thereof with an opening tube holding portion including a bottom having the same shape as the opening tube and a pair of fixed walls rising from the bottom. A split claw portion is formed on the outer surface of the distal end of the fixed wall of the stopper tube holding portion to be hooked on a step formed on the inner peripheral surface of the recessed portion of the head of the cassette cylinder. A center portion of the other arm member is provided with a recess in which the stopper tube holder is rotatably fitted. A through hole is formed in the center of the pair of arm members so as to penetrate a connection tube connected to the combustion part of the stove body, and the connection tube and the stopper tube are connected through the through hole. A lock portion protruding left and right is formed at the end of the connection cylinder of the stove main body, and a passage hole of the lock portion is formed continuously with a through hole formed in a central portion of the pair of arm members.

The pair of arm members are aligned in a straight line,
With the opening tube positioned on the bottom side of the opening tube holding portion, the split claw portion of the opening tube holding portion of the arm member is attached to the step formed on the inner peripheral surface of the head recess of the cassette cylinder. Fit it. Thereafter, the stove body and the cassette cylinder are pressed against each other to position the opening tube on the split claw side of the opening tube holding portion, and the lock portion of the connection tube is formed at the center of the pair of arm members. When the pair of arm members are opened in a cross shape while passing through the hole, the lock portion is located inside the bottom of the opening tube holding portion formed on the arm member, and the opening tube is in the opening tube holding portion. The pair of arm members and the cassette cylinder are fixed while being held at the position of the split claw part.

In the above-described cassette cylinder mounting device, a pair of mounting arm members can be aligned in a straight line before mounting, so that a thinner portable gas stove can be obtained.
