Abstract: To provide a highly exceptional, innovative head-mounted front illumination device in which when the head is slightly tilted as normal, the line of sight is directed further downward, and the area near the hands is looked at, the illumination range is automatically changed in correspondence with the downward eye movement and the area near the hands at the end of the line of sight is illuminated, and when the head is raised, the original forward direction is automatically illuminated again.

Abstract: There is provided a burner to be used for a portable gas cooking stove, including (a) a mixture gas pipe having an open end through which a gas mixture of combustible gas and air is exhausted, (b) a burner head connected to the mixture gas pipe in a hermetically sealed condition and having at least one opening at a surface thereof, the gas mixture blowing out through the opening, and (c) an igniter igniting the gas mixture blowing out through the opening of the burner head, the igniter generating a spark in a direction perpendicular to a flow of the gas mixture blowing out through the opening of the burner head. The burner makes it possible for the spark to make contact with the gas mixture flow in a larger contact area than that of a conventional burner. Accordingly, it is possible to stably ignite the gas mixture, even if the gas mixture has a great flow velocity.

Abstract: There is provided a portable gas cooking stove, including (a) a mixture gas pipe having an open end through which a mixture gas of combustible gas and air is exhausted, (b) a burner head connected to the mixture gas pipe in a hermetically sealed condition and having at least one opening at a surface thereof, the mixture gas blowing out through the opening, (c) an igniter igniting the mixture gas blowing out through the opening of the burner head, and (d) a windscreen surrounding the burner head and formed with a flame hole facing the opening of the burner head, the igniter being located outside the windscreen in facing relation to the flame hole. The portable gas cooking stove makes it no longer necessary to provide a net to an inner wall of a burner head, which was necessary to do in a conventional gas cooking stove, ensuring reduction in a period of time necessary for fabricating a flame hole and simplification in steps of fabricating a flame hole.

Abstract: There is provided a globe supporting structure that supports a globe of a gas lantern which burns combustible gas discharged from a gas cartridge containing the combustible gas by means of a burner head located inside the globe, including a ventilator positioned above the globe, a plurality of wires rotatably arranged on the ventilator, each of which rotates about the ventilator, and is shaped so as to be capable of reaching a bottom surface of the globe, and a globe supporting plate that supports the globe, and is provided with first arrangement which is detachably engagable with a portion of the wires reaching the bottom surface of the globe. In accordance with the globe supporting structure, the globe can be removed easily from the globe supporting plate without breaking the globe.

Abstract: There is provided a burner structure used for a portable gas cooking stove, including a mixing tube with an open end from which a mixture gas of a combustible gas and air is discharged, a burner head with a predetermined volume, an open bottom surface, and a top surface with at least one opening, an inner cup having a size that enables the inner cup to be housed in the burner head, and an open bottom surface, and a bottom plate with a through-hole through which the mixing tube can be inserted, covering the open bottom surface of the burner head, wherein the inner cup is installed inside the burner head in such a manner that an inner surface of the inner cup faces the mixing tube, and the mixing tube is installed on the bottom plate so that the open end is positioned higher than a bottom surface of the inner cup.
