Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a stabilizing foot for a combustion appliance, and more particularly to a stabilizing foot for stably holding a combustion appliance having a fuel tank at the bottom thereof.

(Prior Art) Conventionally, combustion appliances have a fuel tank, especially a disposable fuel tank, at the bottom (herein, combustion appliances are appliances that utilize combustion of gas ejected from a fuel tank, such as gas stoves, gas lanterns, etc.) In general, there is no means for stably standing the combustion appliance upright, and therefore, it is difficult to stand the combustion appliance stably upright on uneven ground. It was difficult.

Therefore, a stabilizing device for such combustion appliances was proposed, but even this stabilizing device was flat and had a structure that hardly protruded downward from the fuel tank, so it was difficult to use this stabilizing device. However, the stability of the combustion appliance is not necessarily sufficient, and the flat shape also makes it difficult to carry.

(Object of the Invention) The present invention solves the problems of the conventional stabilizing devices for combustion appliances described above, and provides a stabilizing foot for combustion appliances that has a simple structure and can hold the combustion appliance extremely stably. The purpose is to

(Structure of the Invention) The stabilizing leg for a combustion appliance of the present invention includes at least three stabilizing leg pieces, a locking piece protruding from a predetermined position on the upper surface of each of these stabilizing leg pieces, and an adjacent stabilizing leg. A connecting piece is fixed at one end to one of the pieces and the other end is pivotally connected to the other stabilizing leg, and has a folding position in which the stabilizing legs are positioned in parallel and an operating position in which the stabilizing legs are opened radially. When the combustion appliance is locked by the locking piece in the working position,
It is characterized in that the outer end of the stabilizing leg protrudes diagonally outward and downward from the combustion appliance.

As mentioned above, the combustion appliances include all appliances that utilize combustion of gas ejected from a fuel tank, such as gas stoves and gas lanterns.

The connection piece is a stopper that, when the stable leg piece is expanded to the operating position, hits the stable leg piece on the pivoted side and positions the adjacent stable leg pieces at a predetermined angular position. It is desirable that the

(Operations and Effects of the Invention) In the stable leg piece for a combustion appliance of the present invention, when necessary, each stable leg piece can be expanded until the connecting piece touches one of the adjacent stable leg pieces. Since the stabilizing foot is positioned at the working position, it is sufficient to place it on the ground surface in this state. Thereafter, the combustion appliance can be held by placing the combustion appliance on the stabilizing foot so that the fuel tank is placed inside the locking piece. At this time, since the outer ends of the stabilizing legs protrude diagonally outward and downward from the fuel tank of the combustion appliance, the combustion appliance can be stably held even if the ground surface is somewhat uneven.

As will be explained in detail later in the Examples section, a recess is formed on the inner surface of the root of each of the above-mentioned locking pieces, and the annular protrusion that may be present at the bottom peripheral edge of the fuel tank is inserted into the recess. In order to more securely hold the combustion appliance, first, the annular protrusion of the fuel tank is fitted into the recess of the stabilizer leg in the folded state,
In this state, if each stabilizing leg piece is expanded in the same manner as described above, the stabilizing leg piece can be easily attached to the combustion appliance.

Furthermore, when the stability leg of the present invention is not in use, it can be folded from the unfolded position to the folded position, resulting in a very compact structure that can be stored in a small space and is convenient to carry. Furthermore, since the stabilizing leg of the present invention is separate from the fuel tank of the combustion appliance, even if the fuel tank is disposable, it can be used repeatedly and is economical.

(Example) Hereinafter, a stabilizing foot for a combustion appliance according to an example of the present invention will be described with reference to the accompanying drawings.
