Description

  The present invention relates to a fire hose having high visibility in daytime and in the dark.

  Generally, fire hoses used for fire fighting activities in buildings such as buildings are transported in a flattened state or in a folded state, and are stretched during use.

  However, the building that caused the fire may be out of power, or may have to return while the visibility is poor due to fire smoke. As a countermeasure, firefighters carry lights and perform fire fighting activities. However, most buildings are often entered for the first time, and the visibility is worse, so it is possible to get lost and not reach the exit, leading to a serious accident.

  In order to cope with such a situation, there is a method of using a fire hose as a guidance for returning home. Since the fire hose is always connected to an outside pump car, the exit can be reached by following the fire hose. However, it is difficult to find a fire hose when the visibility is poor due to a power failure or fire smoke. As these countermeasures, a method is known in which a reflective material is bonded on a fire hose so that the fire hose can be easily found even in a dark place (see, for example, Patent Documents 1 and 2). Since the reflective material reflects the light, the firefighter can return the fire hose as a road guide even in the dark. Further, as another method for indicating a return path, a method of making a reflecting material into an arrow shape is also known (see, for example, Patent Document 3).

  These reflective materials may fall off due to friction with the ground or the like during fire fighting activities. For this reason, a method of covering the reflecting material with a coating layer to prevent dropping is also known (see, for example, Patent Document 4).

  During fire fighting, many fire hoses are gathered at the fire site from many fire stations and other bases. For this reason, in the collection | recovery of the fire hose after a fire extinguishing, the fire hose of another base may be collected. In order to solve this problem, a method for changing the color of the surface of the fire hose for each base and a method for attaching a display indicating the base are known. As one of the means, a method is known in which the reflecting material is shaped to indicate the location to which the fire hose belongs (for example, see Patent Document 5). These methods increase visibility of the hose in the daytime in addition to displaying the affiliation. For example, the visibility of the fire hose during the daytime can be enhanced by making the hose surface a conspicuous color such as red.

  By the way, the above-mentioned fire hose improves the wear performance of the ear | edge part by making the warp yarn density of the ear | edge part bent when squashed flatly higher than a flat surface. Moreover, the boundary line which shows a boundary is provided so that an ear | edge part and an abdominal part can be distinguished visually.

Utility Model Registration No. 3080507 JP 2001-193874 A JP 2002-139182 A Japanese Patent Laid-Open No. 10-2464 JP 2009-150522 A

  The fire hose described above has the following problems. That is, the discriminability in the dark place can be enhanced by covering the wider area of the fire hose surface with the reflective material. However, if the area covered by the reflective material on the surface of the fire hose is widened, the border indicating the boundary between the ear and the abdomen is covered, or the display indicating the affiliation of the hose is reduced or cannot be attached. There is a case. In this case, there is a possibility that the location to which the hose belongs cannot be determined.

  Moreover, when the daytime visibility is enhanced by the color of the hose surface, the exposed area of the hose surface is reduced by the reflective material, and the daytime visibility is reduced.

  On the other hand, when reducing the area covered by the reflective material on the surface of the fire hose, the visibility of the fire hose in the dark is reduced. Moreover, since the adhesive surface between the fire hose and the reflective material becomes small, the adhesive force is reduced, and there is a problem that the reflective material falls off the fire hose during fire fighting activities.

  Therefore, the present invention provides a fire hose that has sufficient wear resistance, has high visibility in daytime and in the dark, and has sufficient adhesion between the hose surface and the reflector. It is aimed.

  In order to solve the problems and achieve the object, the fire hose of the present invention is configured as follows.

A pair of ears located in a bent portion in a flattened state and a pair of abdomen located in a flattened state in a flattened state and having a lower warp density than the ears, There the hose body is 10mm or more, on one of the outer surface of the pair of abdominal, together along the length of the hose body, provided apart from the boundary between each of the with the abdominal pair of ears, A reflective material having a dimension in a direction perpendicular to the length direction of 3 mm or more and smaller than a dimension in an outer peripheral direction of the abdomen, and the reflective material is provided on an outer peripheral part of the hose body. the abdomen and the pair of boundary lines indicating the boundary between each pair of ears is provided, wherein are provided, the spacing between each of the pair of boundary lines between the reflecting member and And

  According to the present invention, visibility is high in the daytime and in a dark place, and it is possible to provide sufficient adhesion between the hose surface and the reflective material.

The side view which shows the hose for fire fighting which concerns on one embodiment of this invention. The perspective view which fractures | ruptures and shows the principal part of the fire hose. The top view which shows the state crushed by the flat of the fire hose.

  FIG. 1 is a side view showing a fire hose 1 according to an embodiment of the present invention, FIG. 2 is a partially cutaway perspective view showing a main part of the fire hose 1, and FIG. It is a top view which shows the state crushed by.

  The fire hose 1 includes a cylindrical hose body 10, an inflow portion 50 provided in fluid-tight communication with an opening on the proximal end side of the hose body 10, and an opening on the distal end side of the hose body 10 and liquid-tightness. And an outflow portion 60 provided in communication with the main body. The inflow part 50 can be attached to and removed from the fire extinguishing agent supply part S in a liquid-tight manner, and the outflow part 60 can be attached to and detached from the water discharge nozzle T in a liquid-tight manner. The fire extinguisher supply unit S includes a fire hydrant S1 that supplies a fire extinguisher and a guide hose S2 that guides the fire extinguisher to the inflow portion 50. In addition, a fire extinguisher is a substance used for fire extinguishing, such as water, and powder etc. are contained besides water.

  As shown in FIG. 2, the hose body 10 includes an abdomen 13 that is flattened in a flattened state and ears 14 that are bent when flattened. That is, two abdominal portions 13 and two ear portions 14 are formed. The warp yarn density of the ear portion 14 is higher than the warp yarn density of the abdominal portion 13. On the outer peripheral portion of the hose body 10, a broken-line boundary line 15 indicating a boundary between the abdomen 13 and the ear part 14 is provided. Although the color of the hose body 10 is usually white, it is possible to further improve the visibility by making it a color with high visibility in the daytime such as red.

  The abdomen 13 is formed, for example, in a range of 32.5% of the outer periphery of the hose body 10. That is, the two abdominal portions 13 occupy 65% of the outer periphery of the hose body 10. On the other hand, the ear portion 14 is formed in a range of 17.5% of the outer periphery of the hose body 10. That is, both the two ear portions 14 occupy a range of 35% of the outer periphery of the hose body 10.

  The hose body 10 is bent at the ear portion 14 when crushed flat. For this reason, in the top view in a flattened state, as shown in FIG. 3, the ears 13 are located at both ends in the circumferential direction of the hose body 10, and the abdomen 13 is located at the center in the circumferential direction of the hose body 10. To do.

  On the outer periphery of the abdomen 13, a reflector 16 having a dimension P <b> 1 in the outer periphery direction of the hose body 10 is provided along the length direction of the hose body 10 and separated from the boundary line 15. The reflective material 16 is pressed against the outer peripheral surface of the hose body 10 while being heated, and is formed integrally with the hose body 10.

  Since the reflecting material 16 has a property of reflecting light incident on the surface thereof, it has an effect of adding visibility in the dark place to the fire hose 1. When the dimension P1 is small, the reflecting material 16 also reflects less light, so the visibility is not sufficient. Moreover, since the adhesive force with the hose main body 10 also becomes small, there is a possibility of dropping out in the fire fighting activity.

  For this reason, the reflective material 16 needs to make dimension P1 more than predetermined length, and to obtain sufficient visibility and the adhesive force with the hose main body 10. FIG. In order to satisfy these conditions, the dimension P1 is formed to be 3 mm or more.

  Moreover, since the boundary line 15 shows the boundary between the abdominal part 13 and the ear part 14, it is not covered with the reflector 16 and needs to be exposed. For this reason, the upper limit of the dimension P1 is the outer peripheral dimension of the abdomen 13.

  Since the minimum value of the dimension P <b> 1 is defined for the reflector 16, the minimum value is also defined for the outer periphery of the hose body 10. That is, the reflector 16 is formed within the range of the abdomen 13. For this reason, the outer periphery of the abdomen 13 also has a minimum value of 3 mm. Since the abdomen 13 is in a range of 32.5% of the outer periphery of the hose body 10, when the outer periphery of the abdomen 13 is 3 mm, the outer periphery of the hose body 10 is 3 mm / 0.325 = 9.23.

  Note that, when the boundary line 15 is close to the end of the reflector 16, it is difficult to visually recognize the boundary line 15. For this reason, the outer periphery of the hose body 10 is set to 10 mm or more, and the interval P2 between the boundary line 15 and the reflecting material 16 is provided to make the boundary line 15 visible. By making the interval P2 5 mm, for example, it becomes easier to visually recognize the boundary line 15.

  In the fire hose 1 formed as described above, the boundary line 15 between the abdomen 13 and the ears 14 is formed on the outer periphery so as to be identifiable, and the reflector 13 is attached to the abdomen 13. For this reason, the abdominal part 13 and the ear | edge part 14 are distinguishable.

  Further, by setting the dimension P1 of the reflecting material 16 to 3 mm or more, it is possible to prevent the reflecting material 16 from falling off during the fire extinguishing activity, and sufficient visibility is provided in a dark place. Moreover, by defining the upper limit of the dimension P1 of the reflector 16 within the range of the abdomen 13, the entire surface of the hose body 10 is not covered, and the visibility of the daytime is enhanced by the color of the hose body 10 surface.

  As described above, the fire hose according to the present invention has sufficient wear resistance, has high visibility in the daytime and in the dark, and is sufficient between the hose surface and the reflective material. It becomes possible to provide a strong adhesive force.

  The present invention is not limited to the above embodiment. For example, in the above-described example, the case where the reflective material continues along the hose body has been described, but the present invention can be similarly applied even when the reflective material is provided intermittently. Moreover, the range of the abdominal part in the outer periphery of the hose body is not limited to the 32.5% range in the above-described embodiment, and for example, the case can be similarly applied even in the case of 25%. Of course, the present invention can be similarly applied even when the position of the boundary line between the abdomen and the ear is different from that of the above-described embodiment. Of course, various modifications can be made without departing from the scope of the present invention.
