Abstract

PROBLEM TO BE SOLVED: To easily take an emergent step to a damaged part such as a pin hole so as to continue fire fighting, by inserting a short tubular supporter to be slidable in a longitudinal direction, having an inside diameter less than the maximum outside diameter of a hose, around the periphery of the canvas hose in which a connecting metal fitting is attached at its end. SOLUTION: In a fire hose 1, the main body of a hose 2 is formed of cylindrically woven canvas, and connecting metal fittings 3 are attached at both ends of the main body. Then, a short tubular canvas supporter 4 is inserted to be slidable in a longitudinal direction around the periphery of the main body of the hose 2, and the inside diameter of the supporter 4 is formed to be set to the same as or less than the maximum outside diameter D1 of the hose 2. Hereby, when a pin hole is produced in the hose 2, a condition is set that water is stopped to be fed or water pressure is lowered and the supporter 4 is moved up to a position to cover the pin hole, and after that, water pressure is returned to a normal condition again, so that the main body of the hose 2 is expanded and the pin hole is sealed by the supporter 4, thus water leakage can be prevented.

2. Description of the Related Art In general, a fire hose has a hose body made of a tubular fiber fabric. On the other hand, a fire hose during a fire extinguishing operation may be violently dragged on a concrete road surface or may hit an obstacle on the road surface, so that the cloth hose body may be damaged such as a pinhole or a tear. However, if the fire extinguishing operation is continued while leaving such damage, the damaged portion may expand due to water pressure, and eventually burst, making the fire extinguishing operation impossible.

In order to achieve the above object, according to the present invention, a short tubular supporter having an inner diameter equal to or less than the maximum outer diameter of a hose is provided on the outer periphery of a cloth hose having a connecting fitting attached to an end thereof. It is extrapolated so as to be slidable in the direction. Here, the maximum outer diameter means the outer diameter of the hose body when the fire hose is in an expanded state when water is passed through. Also, being slidable means having a handling property such that a normal firefighter can manually move the supporter in the longitudinal direction along the hose body in a state where water is not passed through the fire hose.

When the supporter is slidably inserted into the hose as described above, if the hose is damaged such as a pinhole, the water pressure is reduced, the supporter is moved to a position covering the damaged portion, and then the supporter is moved again. When the water pressure is returned to normal, the supporter comes into close contact with the damaged portion due to the expansion of the outer diameter of the hose, thereby sealing water leakage from the damaged portion, and further preventing rupture due to further expansion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to an embodiment shown in the drawings. 1 and 2 show a fire hose according to an embodiment of the present invention. In the fire hose 1 of the present invention, the main body of the hose 2 is made of tubular woven cloth, and the connecting fittings 3 are attached to both ends thereof. A supporter 4 made of a short tubular cloth is externally slidably provided on the outer periphery of the main body of the hose 2 in a longitudinal direction. Its inner diameter D 2 of the supporter 4 are formed so as to maximum outer diameter D 1 and the same or less hose 2.

[0007] Since the supporter 4 is extrapolated to the outer periphery of the main body of the hose 2 as described above, when a pinhole occurs in the hose 2, the water supply is stopped or the water pressure is reduced, and the supporter 4 is turned off. When the water pressure is returned to a normal state again after moving to a position covering the pinhole, the pinhole is sealed by the supporter 4 by expanding the hose 2 main body, thereby preventing water leakage. Further, the pinhole does not expand and burst due to the close contact of the supporter 4 as described above.

Since the supporter 4 performs such an operation,
Supporter inside diameter D 2 of 4 are the following maximum outer diameter D 1 and the same or hose 2. More preferably, the inner diameter D 2 of the supporter may be in the 0.2 to 1.0-fold of the hose maximum outer diameter D 1. The number of the supporters 4 to be extrapolated per fire hose may be one or a plurality, and is not particularly limited. The position where the supporter 4 is extrapolated onto the hose 2 may be at any position in the longitudinal direction of the hose 2, but is preferably near the connecting portion to the connecting fitting 3. Since the fire hose 1 collides with the road surface due to heavy use or is dragged, the hose 2 is connected to the connection fitting 3 at that time.
It is likely to be damaged by being sandwiched between the hard connecting fitting 3 and the road surface. Therefore, if the supporter 4 is placed around the connection of the hose 2 to the connection fitting 3, the protection effect of the connection to the connection fitting 3 can be enhanced as described above.

The supporter 4 is preferably made of the same tubular fabric as the main body of the hose 2, and more preferably the inner peripheral surface of the supporter is coated with a synthetic resin film such as a polyurethane elastomer or polyester elastomer as a lubricant. By coating the sliding material in this way, the supporter 4 can easily slide on the hose 2,
In addition, the adhesion when the pinhole or the like is covered can be further improved.

The material of the supporter 4 may be different from that of the hose 2, for example, a rubber or plastic tube as long as the function of the fire hose 1 is not impaired. The rubber or plastic may be reinforced with short fiber or long fiber fiber reinforcement. The fire hose 1 thus obtained is mainly mounted on a fire engine and connected to a plurality of fire hoses at a fire site for fire extinguishing. Then, when water leaks due to the formation of a damaged portion such as a pinhole or a tear in the middle of the hose 2 during the fire extinguishing work, the water supply is stopped or the water pressure is slightly reduced, and the supporter 4 is slid over the damaged portion to cover it. By doing so, it is possible to prevent water leakage in an emergency and further prevent rupture due to enlargement, so that fire fighting work can be continued.

As described above, according to the fire hose of the present invention, the short tubular supporter is extrapolated. Therefore, when a damaged portion such as a pinhole is generated in the hose body, the damage is prevented. If the supporter is slid to the damaged portion, emergency measures such as water leakage prevention can be performed, so that the fire extinguishing operation can be continued without substantial interruption.
