Description

The present invention relates to a flame tube that can be brought into and out of the water by using a heating tube and a battery as the ignition device of the flame tube, and further combining with a special case made of metal with an air bag (a floating ring with a gas generator).

Many of the currently used flame cylinders are ignited by rubbing a sliding paper on the pyrotechnic part of the flame cylinder head, and it is difficult to ignite if it gets wet in rainy weather.

Conventional flame tubes were ignited using an explosive and sliding paper, making it difficult to ignite in places with water. An object of the present invention is to provide an automatic ignition type flame cylinder that can ignite a flame cylinder even in the presence of water and can be carried extremely safely by combining with a case made of metal, and can be carried on the water or in water.

In the present invention, a heating wire and a battery are used as the ignition device, and a metal exclusive case with an air bag (a floating ring with a gas generator) is combined with the ignition device to be brought into water and water.

The auto-ignition flame tube shown in Fig. 1 can be completely waterproofed by being housed in a metal case, so it can be brought into the water or water, and it can be ignited alone on the water by attaching an air bag. Become.

Hereinafter, embodiments of the present invention will be described with reference to FIGS.

When using the auto-ignition type flame cylinder with air bag shown in FIG. 1, the flame cylinder body attached to the metal case (grip, 10) is extracted from the metal case (cover, 11), and the safety device release ring (15) is pulled strongly. As a result, the insulating plate (6) and the gas opening / closing plate (7) are extracted from the head of the battery (5) of the flame generating cylinder body (1). By turning on the switch (13), the heating wire (3) installed in the pyrotechnic part (2) of the flame cylinder head is energized and ignited. At the same time, gas is sent from the gas generator (9) to the air bag (14) wound around the flame cylinder main body (1), and the gas swells as shown in FIG. 3 to enable ignition on the water alone. A non-combustible sheet (16) is attached to the upper portion of the air bag (14) main body, and air leakage due to sparks of the flame generating cylinder can be prevented. By using an O-ring (12) at the joint of the flame tube case (10, 11), it can be completely waterproofed and can be brought into the water. A simple waterproofing is applied to the flame tube main body so that it can be used on the water surface.

2 is used, the safety device release ring (15) is pulled strongly from the flame cylinder body (1), the insulating plate (6) is pulled out from the battery (5) head, and the switch (13) is inserted. As a result, the heating wire (3) installed in the pyrotechnic part (2) of the flame tube head is energized to enable ignition. When it is difficult to ignite due to battery discharge or the like, the waterproof tape (19) is peeled off and the ignitable paper provided in the tape can be ignited.

The auto-ignition type flame cylinder with an air bag shown in FIG. 1 is a small and safe portable rescue request signal that is effective in all weather conditions when seeking rescue on the water when encountering an accident in marine sports or the like. Because it is completely waterproof, it can be carried underwater by scuba diving. Note that, unlike the flame tube shown in FIG. 2, it is not possible to deal with battery discharge or the like, so inspection before use is indispensable.

The auto-ignition flame tube shown in FIG. 2 is contained in a metal case, so it can be carried very safely, and is a rescue request signal that is effective in all weather conditions when seeking rescue due to distress or injury during leisure or climbing.

It is sectional drawing of the auto-ignition type flame cylinder with an air bag. It is a sectional view of an automatic ignition type flame cylinder. It is sectional drawing at the time of use of the automatic ignition type flame cylinder with an air bag.
