Abstract
Description
[Technical field]
[0001] The present invention relates to a fire hose. [Background technology]
[0002] Conventionally, a fire hose has been known in which a plurality of directional markings are arranged at intervals along the longitudinal direction of the hose on the outer peripheral surface of the hose body in order to provide guidance to firefighters, each of the directional markings being composed of a first marking portion and a second marking portion adjacent to each other in the longitudinal direction of the hose, the first marking portion having a first color and the second marking portion having a second color (Patent Document 1, etc.). [Prior art documents] [Patent documents]
[0003] [Patent Document 1] JP 2020-203019 A Summary of the Invention [Problem to be solved by the invention]
[0004] In the past, when a fire broke out, the roofs and walls of houses fell off, so firefighters could fight the fire by spraying water from outside. However, now that airtight, highly insulated houses have become widespread, there are more and more firefighting scenes where firefighters are forced to enter inside the building to fight the fire. Even if fire hoses and search ropes are used as lifelines, it is difficult to see them in the thick smoke (darkness). Furthermore, when engaging in firefighting activities, firefighters are always at risk of having their hands full and their field of vision restricted by face masks (air breathing apparatus), and when entering and evacuating, not only indoors but also outdoors at night, firefighters are always at risk of increased effort in deployment and withdrawal work due to fire hoses and search ropes getting tangled in obstacles, and transportation problems (stepping on or tripping over the fire hoses).
[0005] The above-mentioned conventional fire hose with a guidance function can identify the evacuation direction, but it does not tell the distance to the evacuation position, and therefore it is not possible to know where the person is located indoors.
[0006] When firefighters are fighting a fire indoors, for example, if there is a person in need of rescue indoors, they communicate with the outside world to inform them of the person's location when calling for help. However, if the power goes out at night and the room is filled with smoke, and even if you shine a light, you can only see a short distance, it is not possible to carry out a swift rescue operation if you do not know where the person is located inside the room.
[0007] In addition, when firefighters are engaged in indoor firefighting activities, they carry oxygen tanks for breathing apparatus on their backs and enter the building to carry out firefighting activities. However, because there is a time limit on the oxygen tank, they must estimate their approximate entry distance based on the distance they have traveled and estimate their range of movement accordingly. However, if they make a wrong estimate, it could lead to an accident.
[0008] Furthermore, for example, at the scene of a building fire, when extinguishing a fire in a room on an upper floor, it is necessary to measure the height of the room on the upper floor in order to set the water pump pressure, but this measurement cannot be made with the above-mentioned conventional fire hose.
[0009] In addition, for example, firefighters heading to an indoor fire scene can easily carry out rescue operations while ensuring the safety of rescuers if they can know how close they are to the source of the fire as they enter the building where the fire is, and how far they are from the source of the fire as they exit the building. However, this is difficult to achieve with conventional fire hoses.
[0010] To provide a fire hose which has a guiding function and can grasp the approximate distance into a building and the approximate height from the ground, and also has an object to provide a fire hose which can grasp how close or far away it is from the source of a fire. [Means for solving the problem]
[0011] In order to achieve the above object, a fire hose according to one embodiment of the present invention comprises a hose body, a male fitting attached to one end of the hose body, and a female fitting attached to the other end of the hose body, the hose body having a plurality of distinguishable identification marking regions that divide the hose body evenly along the length.
[0012] The plurality of identification display regions may be configured by uniformly coloring the hose body with different colors along the length direction.
[0013] The plurality of distinguishable display regions may include one or more of a chromatic color fill, a mesh pattern, a vertical stripe pattern, and a horizontal stripe pattern.
[0014] The identification display area may be colored such that the colors gradually change from warm to cool in a clockwise direction on a color wheel from the male joint side to the female joint side.
[0015] The length of the hose body may be 20 to 22 meters, and the number of the identification marking regions may be 4, 5, 8, or 10.
[0016] A fire hose according to another embodiment of the present invention comprises a hose body, a male fitting attached to one end of the hose body, and a female fitting attached to the other end of the hose body, the hose body having four or more identification markings evenly distributed at intervals along the length of the hose body, the four or more identification markings being colored in a clockwise direction on a color wheel, gradually changing from warm colors to cool colors from the male fitting side to the female fitting side. Effect of the Invention
[0017] The fire hose of the present invention has a plurality of identifiable identification areas that divide the hose body evenly along the length of the hose. From the length of each identification area, the approximate distance from the end of the fire hose can be determined, allowing the firefighters to determine the approximate distance they will have entered a building when extinguishing a fire, and also allowing the fire hose to be used to determine the approximate height from the ground.
[0018] In addition, the identification markings are evenly distributed along the length of the hose body and are colored in four or more colors that change from warm to cool colors clockwise on the color wheel from the male coupling side to the female coupling side, making each identification marking distinguishable from each other.By doing so, the spacing between each identification marking allows the firefighters to determine the approximate distance they have entered a building when performing firefighting activities, and also allows them to determine the approximate height from the ground when using the fire hose.
[0019] Furthermore, by arranging the colors of the identification display area or the identification display portion so that the colors gradually change from warm to cool in a clockwise direction on the color wheel from the male joint side to the female joint side, it is possible to intuitively grasp how close or far away one is from the source of the fire.

[0021] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A fire hose according to an embodiment of the present invention will be described below with reference to Figures 1 to 13. Note that the same or similar components are denoted by the same reference numerals throughout the embodiments.
[0022] Fig. 1 shows a first embodiment of a fire hose according to the present invention. Referring to Fig. 1, the fire hose 1 includes a hose body 2, a male joint 3 attached to one end of the hose body 2, and a female joint 4 attached to the other end of the hose body 2.
[0023] The hose body 2 is provided with a plurality of distinguishable identification marking areas 5a, 5b, 5c, and 5d that are evenly divided along the length of the hose body 2 and can be distinguished from one another. In the first embodiment, the identification marking areas 5a, 5b, 5c, and 5d are formed by uniformly color-coding the hose body 2 with different colors along the length. For example, the identification marking area 5a is red, the identification marking area 5b is yellow, the identification marking area 5c is green, and the identification marking area 5d is blue, and the identification marking areas 5a to 5d are colored by filling in different colors. Since achromatic colors are difficult to distinguish in a dark place, chromatic colors are preferably used for the color-coded pattern by filling in.
[0024] A flat hose with a nominal length of 20 meters is generally used as a fire hose. The nominal length is the length displayed on the hose body 2 of the fire hose 1, and displaying it is mandatory. Since an error of +10% is allowed for the nominal length, the length of the hose body 2 with a nominal length of 20 meters is 20 to 22 meters. The inner diameter (nominal) of the hose body 2 of the fire hose 1 is generally 65 mm, 50 mm, or 40 mm. Note that the illustrated fire hose 1, including other embodiments, is illustrated with the dimensional ratios of the hose body 2, male joint 2, and female joint 4 exaggerated to make it easier to grasp the overall configuration, and is different from the dimensional ratios of the actual product. One side is shown in FIG. 1, but the opposite side is also shown in the same way.
[0025] In the example shown in FIG. 1, when the length of the hose body 2 is approximately 20 meters, the four color identification marking regions 5a, 5b, 5c, and 5d are color-coded evenly along the length of the hose, and the lengths A to D of each of the identification marking regions 5a, 5b, 5c, and 5d are approximately 5 meters.
[0026] The hose body 2 has a hose jacket made of synthetic fiber warp and weft woven into a cylindrical shape, and the inner surface is lined with a rubber or synthetic resin lining (not shown). The male joint 3 and female joint 4 are plug-in type coupling joints known as Machino type, but other types, such as screw type coupling joints, can also be used.
[0027] Of the warp and weft threads that make up the hose jacket, the weft threads are mostly hidden by the warp threads, and the warp threads are mainly exposed on the surface of the hose jacket. Therefore, by using colored threads that are evenly colored into four colors for the warp threads of the hose jacket, it is possible to manufacture a fire hose 1 having identification display areas 5a to 5d that are evenly colored into four colors as shown in Figure 1. The weft threads of the hose jacket are basically uncolored threads (white), but colored threads can also be used.
[0028] Compared to conventional colored hoses (colored hoses) that are colored by painting the exterior of the hose body 2, the hose body 2 using colored yarn (yarn dyed) does not become hard, can be used as easily as a white (uncolored) hose, and has excellent properties such as almost no stiffness, bending, or color fading due to aging, and maintains its vivid color even after several years. In addition, the length and color of the colored area can be freely and easily set with colored yarn. Furthermore, no new capital investment is required to use colored yarn, and fire hoses can be manufactured using existing manufacturing equipment (circular looms) and conventional manufacturing methods.
[0029] The identification display areas 5a, 5b, 5c, and 5d are arranged so that the colors gradually change from warm to cool in a clockwise direction of the color wheel from the male coupling 3 side to the female coupling 4 side. Warm colors are warm-looking colors such as red, orange, and yellow, while cool colors are cool-looking colors such as blue-green, blue, and blue-purple, and intermediate colors that do not belong to either warm or cool colors such as yellow-green, green, and purple.
[0030] Referring to Figure 2, in the PCCS (Practical Color Coordinate System) color wheel (the original color wheel is displayed in chromatic colors, but Figure 2 is displayed in grayscale), the following colors are arranged clockwise: 1: pR (purplish red / ruby red, rose red), 2: R (red / poppy red, carmine), 3: yR (yellowish red / vermillion, scarlet), 4: rO (reddish orange / poppy red, carmine), 5: O (orange), 6: yO (Yellowish orange / marigold), 7: rY (reddish yellow), 8: Y (yellow), 9: gY (greenish yellow / lemon yellow), 10: YG (Yellow green / leaf green), 11: It is divided into 24 colors: yG (yellowish green), 12: G (green / emerald green), 13: bG (bluish green / viridian), 14: BG (blue green / peacock green), 15: BG (blue green), 16: gB (greenish blu / cyan), 17: B (blue / cerulean blue), 18:B (blue / cobalt blue), 19: pB (purplish blue / wisteria), 20: V (violet), 21: bP (bluish Purple), 22: P (Purple), 23: rP (reddish purple), 24: RP (red purple). Of these, 1 to 8 are warm colors, 13 to 19 are cool colors, and 9 to 12 and 20 to 24 are neutral colors. To arrange colors in a way that transitions from warm to cool in the clockwise direction of the PCCS color wheel, select multiple colors from 1 (pR) to 19 (pB) in a clockwise direction and arrange them. Note that if the color transitions from warm to cool in the counterclockwise direction of the PCCS color wheel, the neutral colors are dark purple colors and may be difficult to distinguish in dark places, which is not preferable.
[0031] A color wheel is a circular representation of the visible light spectrum, and in addition to the PCCS color wheel, there are other color wheels such as the Ostwald color wheel. The wavelength of visible light is 800nm to 400nm, with red at 620 to 800nm, orange at 590 to 620nm, yellow at 565 to 590nm, green at 495 to 565nm, blue at 440 to 495nm, indigo (blue-purple) at 430 to 440nm, and violet at 400 to 430nm, so going clockwise on the color wheel, from warm to cool, the colors correspond to wavelengths of 800nm to 430nm (red to indigo).
[0032] In the hose body 2 shown in FIG. 1, from the male fitting 3 side to the female fitting 4 side, the identification marking area 5a is a warm red, the identification marking area 5b is a warm yellow, the identification marking area 5c is a medium green, and the identification marking area 5d is a cool blue, and colored yarns that are colored red, yellow, green, and blue are used for the warp threads.
[0033] For example, as shown in Figure 3, firefighting activities in a building H where a fire has broken out are carried out in cooperation with firefighter P1 who controls the water discharge from the nozzle N of the fire hose 1 in the building H, firefighter P2 who assists firefighter P1 from the rear and reports the situation by radio, firefighter P3 who advances the fire hose 1 near the entrance to the building H, and commander P4 who communicates by radio with firefighters P2 and P3 and directs the firefighting and rescue activities. Figure 3 shows one fire hose, but at an actual fire scene, many fire hoses and firefighters are mixed together.
[0034] According to the fire hose 1 of the first embodiment, the identification display areas 5a to 5d are color-coded at equal intervals of 5 meters, so that a firefighter P3 near the entrance to the building H can, if he remembers the order in which the colors of the identification display areas 5a to 5d are arranged along the length of the hose, determine the approximate distance that the firefighter P1 has entered the building H by looking at the color-coded pattern that constitutes the identification display areas 5a to 5d, and can share this information with the firefighters P1 and P2 inside the building H and the commander P4 outside the building. Furthermore, even in a smoky and poorly visible place, the color of the identification display areas 5a to 5d arranged in chromatic colors can be distinguished by shining a light on them and looking closely, and the approximate distance of the entry can be grasped by following the color scheme. If the approximate entry distance can be determined, for example, it can be determined how many meters the person is located from the entrance of building H, and the approximate location of the person in need of rescue P5 within building H can be communicated to outside rescue team members P3 and commander P4.This will contribute to rapid rescue operations by rescue team members even if many fire hoses are tangled up inside building H as described above.
[0035] In addition, for example, if rescue team members P1 and P2 are unable to move inside building H where a fire is breaking out and other rescue team members enter the building, if the identification display areas 5a-5d are arranged to gradually change color from warm to cool, the other rescue team members can understand that they are gradually approaching the source of the fire by following the fire hose 1, thereby preventing secondary disasters such as being engulfed in flames during rescue operations and enabling safe rescue operations.
[0036] Also, if you know the order of the colors of the identification display areas 5a to 5d, you can also tell the retreat direction. Since the water discharge nozzle N attached to the end of the fire hose is attached to the male joint 3, if the colors of the hose body 2 are arranged so that they gradually change from warm to cool colors from the male joint 3 side to the female joint 4 side, you can intuitively tell that the warm color side is the fire source side and the cool color side is the water source side, making it easy to tell the retreat direction. Also, the direction of the water flowing inside the fire hose 1 can be known.
[0037] In addition, the fire station branch or fire brigade division that a hose belongs to can be identified by the color-coding of the identification display areas 5a to 5d, so that even if multiple divisions or stations are at the fire scene, the fire hose can be quickly removed.
[0038] Also, for example, at the scene of a building fire, when extinguishing a fire in a room on an upper floor, it is necessary to measure the height of the room on the upper floor to be extinguished in order to set the pump pressure of the water pump to which the fire hose is connected. If the end of the fire hose is lifted up to the room on the upper floor to be extinguished using a ladder or the like, the evenly colored identification display areas 5a-5d can be used to determine the length of each of the identification display areas 5a-5d, and therefore the approximate height from the ground can be determined, and the pump pressure can be set.
[0039] In the first embodiment, the identification display area is divided into four equal areas in the hose length direction, but the number of identification display areas is not limited to four, and other multiple numbers of identification display areas may be provided. However, as described above, the length of the hose body 2 of a commonly used fire hose is 20 to 22 meters. In this case, if the number of identification display areas is 20 or more, the length of the identification display area becomes too short, making it difficult to immediately determine the approximate entry distance, so it is preferable that the number of identification display areas is less than 20, more preferably 10 or less. In addition, when the length of the hose body 2 is 20 to 22 meters, if the number of identification display areas is less than four, the length of one identification display area becomes too long, making it difficult to immediately determine the approximate entry distance, so it is preferable that the number of identification display areas is four or more. If the length of the hose body 2 is about 10 meters, the number of identification display areas can be two or three. In order to gradually transition the multiple identification display areas from warm to cool colors, the number of identification display areas is three or more.
[0040] In the case of a fire hose with a indicated length of the hose body 2 of 20 meters, it is more preferable that the number of identification marking regions is 4, 5, 8 or 10. If the number of identification marking regions is 4, the length of each identification marking region will be 5 meters, if the number of identification marking regions is 5, the length of each identification marking region will be 4 meters, if the number of identification marking regions is 8, the length of each identification marking region will be 2.5 meters, and if the number of identification marking regions is 10, the length of each identification marking region will be 2 meters, and addition and subtraction are easy to perform, making it easy to grasp the distance from the hose end.
[0041] 4 shows a second embodiment of a fire hose according to the present invention. A fire hose 1A of the second embodiment differs from the first embodiment in that a line 6 of a predetermined color is provided over the entire length of the hose body 2, but the other configurations are the same as those of the first embodiment. The line 6 is provided on the ears, midsection, etc. of the hose body 2.
[0042] The color of the line 6 can be the designated color of each fire department or fire brigade. By doing so, it is possible to identify which fire station, which fire brigade, or which branch or division it belongs to by the color of the line 6. The color of the line 6 is preferably different from the color of the identification display parts 5a, 5b, 5c, and 5d, but it may be the same color as any of the identification display parts. The width of the line 6 can be, for example, 0.5 to 3.5 cm.
[0043] Next, a third embodiment of a fire hose according to the present invention will be described with reference to Fig. 5. In the third embodiment, a fire hose 1B has hose body 2 divided into four evenly spaced areas 5a, 5b, 5c, and 5d along the length direction, each of which is configured with a horizontal stripe pattern (border pattern) of a different color scheme, making them distinguishable from one another.
[0044] The horizontal stripes constituting the identification display areas 5a, 5b, 5c, and 5d can be composed of horizontal stripes of chromatic colors and chromatic colors, or horizontal stripes of chromatic colors and no color (white). The identification display areas 5a, 5b, 5c, and 5d can be colored so that the colors change from warm to cool in a clockwise direction of the color wheel from the male joint 3 side to the female joint 4 side. For example, the identification display area 5a can be a horizontal stripe pattern of red and no color (white), the identification display area 5b can be a horizontal stripe pattern of yellow and no color (white), the identification display area 5d can be a horizontal stripe pattern of green and no color (white), and the identification display area 5e can be a horizontal stripe pattern of blue and no color (white). Note that one side is shown in FIG. 5, but the opposite side also appears in the same way.
[0045] The hose body 2 having the horizontal stripe pattern of the third embodiment can also be produced by weaving colored yarns, which are colored (dyed) in the desired color along the length, as warp yarns. The number of identification display areas of the third embodiment is also preferably less than 20, more preferably 10 or less.
[0046] Next, a fourth embodiment of the fire hose according to the present invention will be described with reference to Fig. 6. Fig. 6(a) is a plan view of the back side of Fig. 6(b). In the fire hose 1C of the fourth embodiment, the hose body 2 is divided into four equal sections along the length direction, and each of the identification display areas 5a, 5b, 5c, and 5d is configured with a vertical stripe pattern (striped pattern) of a different color scheme, making it possible to distinguish one from another.
[0047] In the fourth embodiment shown in Fig. 6, the identification marking areas 5a, 5b, 5c, and 5d can be arranged so that the colors gradually change from warm to cool in a clockwise direction of the color wheel from the male fitting 3 side to the female fitting 4 side. For example, the identification marking area 5a can be arranged in a vertical stripe pattern of red and no color (white), the identification marking area 5b can be arranged in a vertical stripe pattern of yellow and no color (white), the identification marking area 5d can be arranged in a vertical stripe pattern of green and no color (white), and the identification marking area 5e can be arranged in a vertical stripe pattern of blue and no color (white). The vertical stripes of the identification marking areas 5a, 5b, 5c, and 5d are each formed by vertical stripes aligned in a line along the length of the hose.
[0048] The fire hose 1C with the vertical stripe pattern of the fourth embodiment can be produced by alternately arranging and weaving a group of colored warp threads, which are colored in a desired color, and a group of inexpensive uncolored (white) warp threads, without using uncolored (white) warp threads, but preferably, the fire hose 1C can be produced by alternately arranging and weaving a group of colored warp threads, which are colored in a desired color, and a group of inexpensive uncolored (white) warp threads. Uncolored (white) weft threads are preferably used for the weft threads, but colored threads can also be used. The number of identification display areas in the fourth embodiment is also less than 20, more preferably 10 or less.
[0049] Next, a fifth embodiment of a fire hose according to the present invention will be described with reference to FIG.
[0050] FIG. 7 shows a fire hose 1D according to a fifth embodiment of the present invention. The fire hose 1D is a combination of the identification display area of the first embodiment and the identification display area of the third embodiment. That is, the identification display areas 5a, 5b, 5c, and 5d of the fire hose 1B according to the third embodiment are each composed of the identification display areas 5a and 5c filled with different colors and the identification display areas 5b and 5d with horizontal stripes of different colors, so that they can be distinguished from one another, and the hose body 2 is divided into four equal parts along the length direction. For example, the entire identification display area 5a is colored red, the entire identification display area 5c is colored blue, the identification display area 5b is colored with red and white horizontal stripes, and the identification display area 5d is colored with blue and white horizontal stripes.
[0051] Next, a sixth embodiment of the fire hose according to the present invention will be described with reference to FIG. 8. The fire hose 1E of the sixth embodiment is divided into four equal sections in the length direction of the hose body 2: an identification display area 5a filled with a chromatic color, an identification display area 5b provided with chromatic vertical stripes, an identification display area 5c with about half 5c1 of the length direction filled with a chromatic color and about half 5c2 of the remaining stripes, and an identification display area 5d with about half 5d1 of the length direction filled with a chromatic color and about half 5d2 of the remaining stripes. The identification display area 5c and the identification display area 5d are colored differently from each other to be distinguishable. The identification display areas 5a to 5d are preferably colored so that the colors gradually change from warm to cool in the clockwise direction of the color wheel from the male joint 3 side to the female joint 4 side. The gradual change from warm to cool colors also includes a mode in which areas of the same color scheme are adjacent to each other, such as red, red, yellow, and blue. For example, the identification marking regions 5a and 5b can be red, the identification marking region 5c can be yellow (the vertical stripes are yellow 5c2 and white 8), and the identification marking region 5d can be blue (the vertical stripes are blue 5d2 and white 8). The fire hose 1E of the sixth embodiment can be manufactured using colored yarns with a predetermined color coding as the warp yarns, as in the above embodiments, or can be manufactured by applying an exterior coating to a hose jacket woven with uncolored (white) warp and weft yarns without using colored yarns.
[0052] Next, a seventh embodiment of the fire hose according to the present invention will be described with reference to FIG. 9. FIG. 9(a) is a plan view of the opposite side of FIG. 9(b). In the fire hose 1F of the seventh embodiment, identification marking areas 5a-5d having vertical stripes of the same color scheme are evenly divided in the length direction of the hose body 2, and can be distinguished from one another by changing the thickness and / or circumferential arrangement of the vertical stripes. Specifically, the identification marking area 5a and the identification mark 5b have vertical stripes of the same thickness, but are shifted from one another in the circumferential direction of the hose body 2. The identification marking area 5c and the identification mark 5d have vertical stripes of the same thickness, but are shifted from one another in the circumferential direction of the hose body 2. The vertical stripes of the identification marking areas 5a and 5b are thinner than those of the identification marking areas 5c and 5d.
[0053] Next, an eighth embodiment of a fire hose according to the present invention will be described with reference to FIG. 10. A fire hose 1G of the eighth embodiment has identification marking areas 5a, 5b, 5c, and 5d that divide a hose body 2 evenly along the length direction. The identification marking areas 5a to 5d of the fire hose 1G are configured to be distinguishable from each other by the identification marking area 5a filled with a chromatic color and the identification marking areas 5b to 5d with horizontal stripes of different thicknesses. The horizontal stripes can be configured with a chromatic color and no color (white), or the horizontal stripes can be configured with different chromatic colors. The identification marking areas 5a to 5d can be horizontal stripes of the same color, or can be colored so as to gradually change from warm to cool colors from the male joint 3 side to the female joint 4 side.
[0054] Next, a ninth embodiment of a fire hose according to the present invention will be described with reference to Fig. 11. In the fire hose 1H of the ninth embodiment, the hose body 2 is divided evenly along the length direction into an identification marking area 5a filled with a chromatic color, a mesh pattern identification marking area 5b, a horizontal stripe pattern identification marking area 5c, and a vertical stripe pattern identification marking area 5d, which are configured to be distinguishable from one another. The mesh pattern can be provided, for example, by printing on a non-colored (white) area of the hose jacket.
[0055] Next, a tenth embodiment of the fire hose according to the present invention will be described with reference to FIG. 12. The first to ninth embodiments described above show examples of identification display areas that divide the hose body 2 evenly in the length direction, but the fire hose 1I of the tenth embodiment has identification display parts 5a to 5i on the hose body 2 that are evenly distributed at intervals along the length direction of the hose body 2. The identification display parts 5a to 5i are differently colored from each other so that they gradually change from warm to cool colors clockwise on the color wheel from the male joint 3 side to the female joint 4 side, so that they can be distinguished from each other. For example, there are nine identification display parts 5a to 5i, and each is colored differently, for example, red, orange, yellowish orange, yellow, yellowish green, green, blue-green, greenish blue, and blue.
[0056] Since the identification display parts 5a to 5i gradually change from warm to cool colors, for example, rescue team members who enter a building where a fire is occurring can intuitively grasp how close they are to or how far they are from the source of the fire by watching the change in color as they proceed along the hose body 2.
[0057] The identification display parts 5a to 5i preferably have a shape that indicates the direction of the evacuation direction, and in the illustrated example, have an arrow-shaped pattern. By clearly indicating the shape that indicates the direction of the evacuation direction, the evacuation direction can be more accurately known. The identification display parts 5a to 5i can be formed, for example, of a sheet body attached to the hose body 2. The hose jacket that constitutes the hose body 2 is generally woven with uncolored warp and weft threads, but colored threads different from the color of the identification display parts 5a to 5i can also be used for the warp and / or weft threads.
[0058] The sheet members constituting the identification display portions 5a-5i can be made visible in the dark by being provided with retroreflective, phosphorescent, or fluorescent properties. Although the identification display portions 5a-5i are illustrated only on one side of the hose body 2, they can also be provided on the opposite side in the same manner.
[0059] The identification display parts 5a to 5i have the same arrow shape that constitutes the pattern, but can be distinguished from each other by combining them with different colors, and by arranging them at equal intervals, it is possible to grasp the approximate distance from the end of the hose body 2. For example, in the example shown in FIG. 10, the hose body is about 20 meters long, and the lengths A to J are each about 2 meters. By memorizing the color sequence of the identification display parts 5a to 5i, rescue firefighters can identify the types of colors by shining a light and approaching even in a dark place indoors, and if they can identify the colors, they can grasp the approximate distance of entry. In addition, it is possible to grasp the height of the floor above the ground using the fire hose.
[0060] Next, an eleventh embodiment of the fire hose according to the present invention will be described with reference to FIG. 13. The fire hose 1J of the eleventh embodiment is a modification of the tenth embodiment, and the shape of the identification display parts 5a to 5i is a so-called young leaf mark shape, and numbers (2, 4, 6, . . . 18) indicating the distance (meters) from the end of the fire hose 1 on the female joint 4 side are displayed. The young leaf mark shape indicates the direction of the evacuation direction. The color and other configurations of the identification display parts 5a to 5i of the eleventh embodiment are the same as those of the tenth embodiment. By displaying the numbers indicating the distance, the approach distance into the building can be known more accurately. Even if the numbers peel off or become dirty and difficult to see, by memorizing the order of color arrangement, the identification display parts 5a to 5i are each given a different color, so that the degree of separation from the end of the hose body 2 along the length direction of the hose body 2 can be identified, and the approximate approach distance can be grasped, and the height of the floor above the ground can be grasped using the fire hose. Although only one side surface of the hose body 2 is shown, the identification markings 5a to 5i are provided in the same manner on the opposite side surface.
[0061] The fire hoses 1A to 1J of the second to eleventh embodiments can achieve the same effects as the fire hose 1 of the first embodiment. The present invention is not limited to the above-mentioned embodiments, and the identification display region and the identification display portion can be modified in various ways in terms of the pattern, color, shape, length, etc., without departing from the spirit of the present invention.
