Description

  The present invention relates to a fire hose.

  At the fire site, a plurality of fire hoses are connected and routed from the pump truck that is the water source to the fire site that is the water discharge side. In the case of a building fire, firefighters enter the building with a water discharge nozzle until it is placed, and perform fire fighting activities. Inside the building, it is difficult for light from the outside to reach and it is difficult to understand the return route for evacuating outside the building. Then, when it is necessary to evacuate, such as when the fire is extinguished or when the water is used up, or when the person who needs to be rescued escapes, evacuate outside the building using a fire hose or light.

  During firefighting activities, if the fire site is at night or in a power outage, the building becomes dark. Therefore, it is necessary for fire fighters to return from a building with a complicated structure, relying on a fire hose. For this reason, the method of displaying the female metal fitting side and the water source side like patent documents 1-3 is shown.

  Patent Document 1 describes a fire hose in which a synthetic fiber in which a luminescent substance is blended as a mark or a woven pattern indicating the female fitting side is woven.

  In Patent Document 2, a vertical color line is drawn as an intermittent line, and the length of each part line constituting the intermittent vertical color line changes in the hose length direction with a predetermined regularity. A fire hose that recognizes the direction by decreasing the length of each intermittent part as it goes to the water source fitting side, for example, is described.

  Patent Document 3 describes a fire hose provided with a luminous sheet that indicates an evacuation direction on the outer surface of a hose jacket.

  By the way, Patent Document 1 describes that a mark is woven as a woven pattern, but it does not specifically show how the mark is woven. Usually, a special weaving machine is required, which is not only costly, but because the yarn for forming the mark is woven, the strength of the hose partially changes. Further, Patent Document 2 and Patent Document 3 describe that a vertical color line or mark made of a synthetic resin is attached to a hose jacket. However, since the hose is rubbed by being drawn around the building, Color lines and marks are easily damaged and may be difficult to check.

  Therefore, the present invention provides a fire hose that can be manufactured at a low cost and that the retraction direction can be easily seen by viewing a part.

  A fire hose according to an embodiment of the present invention has a jacket that is woven in a cylindrical shape with a vertical oblique weave structure having warp lines with warp and weft. The fire hose includes a first diagonal pattern portion and a first straight pattern portion. The first oblique line pattern portion is formed by alternately arranging a plurality of first yarns colored in the first color and uncolored base yarns as warp yarns. The first linear pattern portion is configured by arranging a plurality of first yarns as warp yarns following one end portion of the first shaded portion in the circumferential direction of the jacket.

  According to the fire hose according to the present invention, the first pattern constituted by the first diagonal pattern portion and the first linear pattern portion is a rotationally asymmetric pattern, and the first pattern with respect to the first linear pattern portion. It appears as a continuous pattern of arrows pointing in the direction opposite to the side where the angled pattern portion of 1 is an acute angle. This first pattern makes it possible to find directionality in the fire hose. As a result, the fire hose has a function of indicating the retreat direction by associating the first pattern with the direction of the water in the pump car side (water source side) or the hose.

  In addition, since the first pattern composed of the first oblique line pattern portion and the first straight line pattern portion only needs to be arranged as the warp yarn with the first yarn colored in the first color, a special weaving machine is also available. The fire hose of the present invention can be manufactured inexpensively without necessity.
