Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fire hose such as a fire hose connected to a water pump mounted on a fire truck or a fire hose connected to a fire hydrant.
[0002]
[Prior art]
The fire hose includes a hose body that includes a jacket and a lining layer that is lined on the inner peripheral surface of the jacket. Normally, a female connection fitting is attached to one end of the hose body, a male connection fitting is attached to the other end, and a plurality of firefighting units are connected by connecting the female and male connection fittings. The hose can be extended. In addition, in the hose body having a water supply nozzle at one end, a female connection fitting is attached to the other end so that it can be connected to the tip of the extended fire hose.
[0003]
The fire hose is mounted on the fire truck in a serpentine folded state or wound around a drum, and when the fire is extinguished in the event of a fire, the fire hose is lowered from the fire truck and extended, or the drum After extending from and connecting the fittings together, the fire is extinguished by sending water from the water pump to the fire hose.
[0004]
[Problems to be solved by the invention]
By the way, in the case of a building fire on the ground, the fire location can be seen, so when evacuating, it is sufficient to evacuate away from the fire location, but if it is partitioned by a wall like a building fire, the fire Since the location cannot be seen, it may be impossible to determine which direction to evacuate.
[0005]
This invention was made by paying attention to the above circumstances, and its purpose is to look at the arrow indicator attached to the fire hose even when the fire location is not visible, such as a building fire, The evacuation direction is obvious, and it is to provide a fire hose that can be evacuated quickly without getting lost.
[0006]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a hose body comprising a jacket, a lining layer lining the inner peripheral surface of the jacket, and a connection provided at an end of the hose body. A fire hose consisting of a metal fitting or a water supply nozzle has a plurality of hose bodies, and each hose body is provided with a water supply nozzle or a tip side connection fitting at the distal end and a base end side connection fitting at the proximal end. The distal end side connection bracket and the proximal end side connection bracket can be connected, and the distal end side connection brackets or the proximal end side connection brackets cannot be connected to each other. It is extended by connecting with a connection metal fitting, The arrow parameter | index which instruct | indicates the direction of the evacuation direction opposite to the direction which fire-extinguishing water flows is provided in the outer surface of the jacket of the said hose main body.
[0007]
A second aspect of the present invention is the fire hose according to the first aspect, wherein a plurality of arrow indicators are provided on the hose body at a desired interval in the longitudinal direction of the hose body .
[0008]
A third aspect of the present invention is characterized in that the arrow index of the first or second aspect is a reflector.
[0009]
A fourth aspect of the present invention is characterized in that the arrow index of the first or second aspect is applied with a luminous paint.
[0010]
According to the above configuration, since the arrow indicator provided on the outer surface of the hose body indicates the direction opposite to the flow direction of the fire extinguishing water, evacuation in the direction indicated by the arrow indicator evacuates away from the fire place. it can. In addition, when the arrow indicator is formed of a reflective material or is applied with a luminous paint, the presence of the fire hose and the evacuation direction can be understood even at night, so that quick evacuation can be performed.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0012]
1 is a side view of a fire hose, FIG. 2 (a) is an enlarged front view of part A in FIG. 1, (b) is a cross-sectional view taken along line BB, and FIG. FIG. 4 is a front view showing different examples of arrow indicators.
[0013]
As shown in FIG. 1, a hose body 1 of a fire hose is composed of a jacket 2 and a lining layer 3 made of rubber or synthetic resin lined on the inner peripheral surface of the jacket 2. A female connection fitting 4 is attached to one end of the hose body 1, and a male connection fitting 5 is attached to the other end.
[0014]
This hose body 1 is for extension, and can be extended by connecting the female connection fitting 4 with the male connection fitting 5 of another fire hose, as shown in FIG. The female connection fitting 4 at the base end of the fire hose having the water supply nozzle 6 at the tip can be connected to the male connection fitting 5. Accordingly, by connecting the most proximal female connector 4 to which a plurality of fire hoses are connected to a pump (not shown) mounted on the fire engine and feeding fire-extinguishing water, Fire extinguishing water spouts and can perform fire fighting activities.
[0015]
On the outer surface of the jacket 2 of the hose body 1 configured as described above, as shown in FIG. 2, an arrow index 7 is provided that indicates the direction opposite to the flow direction of the fire-extinguishing water. A plurality of arrow indicators 7 are provided in the longitudinal direction of the hose body 1 with a desired interval. The arrow indicators 7 are also arranged in the circumferential direction of the hose body 1 with a desired interval. Also, the arrow index 7 can be visually observed.
[0016]
This arrow index 7 indicates the direction in which the disaster victims evacuate in the event of a fire. For example, if the fire place is partitioned by a wall like a building fire, the disaster victim (or firefighters) may not be able to confirm the fire location. By looking at the arrow index 7 attached to the hose body 1 during the fire fighting activity and evacuating in the direction of the arrow, it is possible to evacuate in the direction away from the fire place and escape the difficulty.
[0017]
The arrow index 7 is preferably made of a material having wear resistance and trauma resistance. Also, as shown in FIGS. 4A to 4C, the design and color of a thick arrow, a combination of a plurality of arrows, etc. are not limited, and characters in the evacuation direction may be displayed near the arrow. Good. Furthermore, the arrow index 7 may be formed of a reflective material, or a luminescent paint may be applied. The arrow index 7 may be fixed to the jacket 2 with an adhesive or the like, or may be printed on the jacket 2.
[0018]
As a reflective material, for example, MR reflective cloth film (manufactured by Unitika Sparklite Co., Ltd.), in particular, the hot-melt adhesive application type 3510 series has good adhesion to the jacket 2.
[0019]
In addition, although the said embodiment demonstrated the fire hose mounted in a fire engine, it is applicable also to a fire hydrant hose, a shape retention hose, etc.
[0020]
【The invention's effect】
As described above, according to the present invention, since the arrow indicator provided on the outer surface of the hose body of the fire hose indicates the evacuation direction, the disaster victim (or the fire brigade) indicates the direction indicated by the arrow indicator. By seeing and evacuating in that direction, you can evacuate away from the fire place. Also, if the arrow indicator is made of a reflective material or applied with luminous paint, the presence of fire hoses and the direction of evacuation can be understood even at night, etc. There is an effect that can be.
