At least a part of the warp fiber is a parallel or twisted fiber having light-reflective material or luminous material on a surface thereof so that a light-reflective or luminous longitudinal portion is formed along a direction of an entire length of the hose on a surface of the jacket.

Description

  The present invention relates to a fire hydrant shape-retaining hose, and more particularly to a fire hydrant shape-retaining hose having reflection and luminous properties.

  As a fire hose for a fire hydrant, a jacket woven using polyester spun yarn or filament yarn for warp and nylon monofilament for weft so as to maintain a circular cross-section so that one person can pull out from the fire hydrant and perform fire fighting activities by himself There is a shape-retaining hose with a relatively small diameter (inner diameter d (FIGS. 1 and 2): about 18 to 41 mm) with a resin tube attached inside.

This shape retention hose is usually installed as an indoor fire hydrant and is always connected to a fire hydrant in a fire proof building. In the event of a fire, it is used for initial fire fighting activities by employees of the fire proof building in particular. It is used for fire fighting activities.
When stored in an indoor fire hydrant facility, the entire shape of the hose body is maintained in a circular cross-section, so water discharge can be started without removing the entire hose from the stored state. In the event of a fire, even one person can operate and discharge the water, so that the initial fire-fighting activity can be effectively performed, and this is a feature of the fire hydrant shape holding hose.

  On the other hand, even if it is a hose for a fire hydrant, in order to start a water discharge activity with a hose (flat hose) that is flattened and bent in a zigzag or wound in a round shape, it is stored. It is necessary to take out the entire hose connected to the valve and arrange it so that the hose is not bent, etc., and then pass the water to discharge it. It is something to do.

  That is, with a flat hose, effective and speedy operation is not possible unless there are two people, and a shape-keeping hose that can be operated by one person is useful as a means for initial fire fighting activities. Incidentally, a flat hose as an indoor fire hydrant usually has an inner diameter of about 40 mm (nominal diameter 40), and is generally thicker and has a larger water discharge amount than a shape retaining hose.

  As described above, the shape retaining hose is always stored in the indoor fire hydrant equipment, and the indoor fire hydrant equipment is provided so as to be embedded in the wall surface of the building. Fire hydrant equipment is usually done only in an emergency by opening a thick and sturdy iron door that is closed.

  Therefore, since the shape-keeping hose is usually placed in the darkness where light does not enter, it absorbs light energy by irradiating light for a certain period of time and converts the stored energy into visible light. Thus, there has been no idea in the past that a phosphorescent material having a function of emitting light is applied to a shape-keeping hose for a fire hydrant.

  On the other hand, when trying to extinguish fire using a fire hydrant equipment in a large building, underground mall, etc., there is a case where it is necessary to perform the fire extinguishing activity in an almost dark situation. In such a case, it is useful for fire fighting activities to be able to grasp the location (storage) location and location (storage) status of the fire hydrant holding hose for fire hydrant and the progress of the hose during fire extinguishing activities instantly and accurately even in a dark situation. It is.

  The fire hydrant equipment itself is equipped with indicator lights that are always lit in red and an alarm bell that informs the fire by sound, so the location of the fire hydrant equipment itself can be understood, but those who actually perform fire fighting activities in an emergency. Therefore, it is extremely effective to be able to grasp the location of the fire hydrant and the storage shape of the fire hydrant holding hose and the progress of the fire hose immediately and accurately in a dark situation as described above.

  In addition, even in normal times when there is no fire, if employees of fire prevention buildings can observe the location (storage) and location (storage) status of fire hydrant shaped hose from around the day, fire prevention awareness It is significant to increase the temperature, and at least, placing things in front of the fire hydrant equipment is considered to be suppressed.

  Looking at the prior art in the patent literature, in order to increase its visibility even in the dark, it is not a shape-keeping hose, but is related to a fire hose that is usually flattened and stored, but a reflective material and a phosphorescent material It has been proposed that a vertical color line extending in the length direction of the hose or an identification character or a symbol is drawn on the hose surface by providing a resin layer containing both of these (Patent Document 1).

Further, regarding fire fighting hoses, it is disclosed to provide an arrow indicator for instructing the evacuation direction on the outer surface of the jacket of the hose body. Particularly, in order to increase the visibility of the arrow indicator, the arrow indicator is made of a reflective material. It is proposed to form or apply a luminescent paint, and it is described that it can also be applied to a shape-retaining hose (Patent Document 2 (paragraph 0019)).
Similarly, in order to increase the visibility in the dark and reduce the amount of expensive phosphorescent paint used, it has been proposed to add a phosphorescent paint with a reflective material added to the fire hose. It is described that it can be applied (Patent Document 3 (paragraphs 0012 and 0021)).

  However, none of these proposals are intended to be applied to a shape-retaining hose, but are related to a fire hose with a large inner diameter and stored in a crushed state. It was unsuitable for application to a fire hydrant shape holding hose with a small diameter.

  In particular, for a fire hydrant shape holding hose having a small inner diameter of about 18 to 41 mm, after forming the hose, the ink paint (phosphorescent paint) containing a reflecting material or the like is successfully applied to a desired location. Was difficult, and there were problems in terms of productivity and manufacturing cost.

It is the perspective view which showed the state which accommodated the fire hydrant shape retention hose which has the reflective and luminous property concerning this invention in the fire hydrant box, and was drawn in the state except the cover part (front door).

  Hereinafter, the shape retention hose for a fire hydrant having the reflection and phosphorescence properties of the present invention will be described in more detail.

  As shown in FIGS. 1 and 2, the shape-retaining hose 1 for a fire hydrant having reflection and phosphorescence according to the present invention has a jacket 2 in which warps and wefts made of synthetic fibers are woven in a cylindrical shape. A fire hydrant shape retaining hose having a lining layer 3 made of a synthetic resin on the inner side surface and having an inner diameter of 18 to 41 mm, and at least part of the warp yarn, the yarn 4 having a reflective material on the yarn surface, and phosphorescence By knitting using the aligned yarn or the twisted yarn of the yarn 5 having the material on the yarn surface, a reflective material portion and a phosphorescent material portion extending in the hose length direction are formed on the surface of the jacket. It is characterized by.

  Here, as shown in FIG. 3A, the aligning yarn is a method of aligning two or more yarns as a single weaving yarn (specifically, depending on the mechanism of the loom). The thread is passed through a heald or a guide or the like, or the twisted yarn is twisted with two or more yarns as shown in FIG. Things that go through the road.

  The shape-keeping hose 1 for a fire hydrant having reflection and luminous properties according to the present invention is a cylindrical shape as a shape-keeping hose 1, that is, without being flattened, as schematically shown in FIG. While maintaining the form, it is wound in a reel shape or a bowl shape and stored in the fire hydrant box 10.

  In FIG. 4, 11 is a fire hydrant valve, and 12 is a shape retaining hose nozzle that serves as a water tip during water discharge. Reference numeral 13 denotes a hose storage support rod, which is turned upward during a fire extinguishing operation to enable the shape retaining hose 1 to be pulled out. In FIG. 4, for convenience of explanation, the lid portion (front door) of the fire hydrant box that normally exists is not drawn, but the interior is drawn with the lid portion (front door) removed.

  A fire hydrant shape retaining hose 1 having reflection and phosphorescence properties according to the present invention includes assembling a yarn 4 having a reflective material on the yarn surface and a yarn 5 having a phosphorescent material on the yarn surface as at least a part of a warp forming a jacket. By being woven using yarns or twisted yarns, a reflector part and a phosphorescent material part extending in the hose length direction are formed on the surface of the jacket, and the reflector part and the phosphorescent material part are When irradiated with light, each of them exhibits a reflection function and a light storage / light emission function. The reflection function is preferably a retroreflection type reflection.

  Since the yarn 4 having a reflecting material on the yarn surface and the yarn 5 having a phosphorescent material on the yarn surface are used as warp yarns as an aligned yarn or a twisted yarn, the portions of the reflecting material and the phosphorescent material are gathered adjacent to each other. As a result, a single linear shape is formed, and visibility is improved.

The shape-retaining hose for a fire hydrant according to the present invention has a reflective / light-accumulating property that extends continuously (in the case of aligned yarn) or intermittently (in the case of twisted yarn) in the hose length direction on the surface of the jacket 2. So that the phosphorescent material portion is always exposed to a certain amount of light when housed in the fire hydrant box 10 so that the phosphorescent material portion can function effectively. It is important to configure fire hydrant equipment. For that purpose, conventional fire hydrant equipment is insufficient, for example,
(1) The main part of the lid (front door) (not shown) of the fire hydrant box is made of a transparent material, such as transparent tempered glass, so that light outside the fire hydrant box can reach the inside of the fire hydrant box. And, at least, when the outside of the fire hydrant box is bright, the phosphorescent material line 7 is configured to be exposed to light.
Or
(2) It is configured so that the light of the fire hydrant indicator light that is always lit to indicate the location of the fire hydrant reaches the inside of the fire hydrant box, and is configured so that the light storage material line 7 is always exposed to light.
Or
(3) A special box internal illumination lamp is always installed inside the fire hydrant box, and the light of the box internal illumination lamp is always configured to strike the phosphorescent material line 7.
It is important to adopt one or a combination of such means.

  Further, the fire hydrant shape retaining hose 1 having reflection and phosphorescence properties according to the present invention extends continuously (in the case of aligned yarn) or intermittently (in the case of twisted yarn) in the hose length direction on the surface of the jacket 2. When the shape retaining hose is irradiated with light, it can reflect the light and inform the fire extinguisher etc. of information such as the state and position of the hose.

  As described above, the shape retaining hose for a fire hydrant of the present invention is combined with a fire hydrant equipment as described above, so that in the event of an emergency such as a fire, even in the dark, through a transparent front door, By opening the door, the location and storage state of the hose in the fire hydrant box can be easily recognized by the light emission of the phosphorescent material and the reflected light with respect to the irradiation light. Furthermore, even when the hose is pulled out from the fire hydrant equipment and used, a part of the hose emits light over the entire length or reflects against the irradiated light, so that the position of the hose and the hose line can be easily confirmed. Also, the return path (retreat path) to the vicinity of the fire hydrant can be easily recognized. Therefore, it becomes possible to perform fire extinguishing activities and retreating from the fire extinguishing site more promptly and accurately, and as a result, safety of those who perform fire extinguishing activities is ensured.

  As described above, in order to effectively receive light irradiation in the fire hydrant box while maintaining a cylindrical cross section as a shape retaining hose, the reflecting material portion and the luminous material portion extending in the length direction of the hose It is conceivable that it is not sufficient to provide only one linear line 6 and 7 formed by each other, and they are arranged at a distance from each other so that effective light irradiation is possible even if light irradiation from one direction is performed. It is important to provide two or more linear shapes 6 and 7, preferably three or more linear shapes 6 and 7. In particular, when two are provided, it is important to provide them at a point-symmetrical position with the central point of the hose cross section as the center of symmetry.

  When the width of each linear shape 6 and 7 is two or more, it is preferable that they are 5 mm or more and 20 mm or less. In particular, in the case where two lines exist in a point-symmetric manner in the case of two lines, when light is irradiated from one direction directly next to the line, if the line width is small, the light This is because there is a case where the effect of irradiation cannot be obtained under a high effect, and a large effect is obtained when the width of each line is relatively large, such as 5 mm or more and 20 mm or less.

  Alternatively, when the number of the linear shapes 6 and 7 is three or more, it is most preferable that the width of each linear shape is 2.5 mm or more and 6.5 mm or less. In the case of three or more lines, even if the irradiation is from one direction, the linear one always has a high light irradiation effect, so the width may be made smaller.

  Alternatively, an aligned yarn or a twisted yarn of a yarn 4 having a reflecting material on the yarn surface and a yarn 5 having a phosphorescent material on the yarn surface may be used over the entire circumference of the hose. In that case, you may use it, mixing with a normal warp over the perimeter or a part suitably.

  The inner diameter (d) of the hose has a range determined as a fire hydrant facility, and in the present invention, it is preferable that the hose has a diameter of 18 mm or more and 41 mm or less because a good effect is obtained.

  As the warp used for the knitting of the jacket (the warp forming the base of the jacket), the use of a spun yarn or a multifilament yarn made of synthetic fibers is excellent in terms of strength, dimensional stability, and productivity. That is important. For example, polyester spun yarn and polyester multifilament yarn.

  Similarly, it is preferable to use a thick synthetic fiber monofilament yarn to maintain a cylindrical shape and maintain shape retention performance, and a nylon monofilament yarn having a diameter of about 0.8 to 1.3 mm, or a polyester monofilament yarn. Etc. can be used suitably.

  It is preferable that the yarn having the reflecting material on the yarn surface includes at least the surface of the resin film provided with the reflecting material layer.

  For example, a reflective material (glass beads, etc.)-Containing resin polyester coated film in which glass beads as a reflective material are applied to a polyester film with a urethane resin as a binder, or a metal (for example, aluminum) as a reflective material on the surface of the polyester film The metal-coated polyester film on which the metal-coated polyester film is vaporized) is twisted with a plurality of so-called slit yarns that are slit to a width of 1 mm, and the appropriate number of twisted yarns and polyester spun yarns are further twisted to obtain one twisted yarn. It is preferable to use the yarn as a yarn because it hardly degrades mechanical properties such as the strength of the entire hose. In the case of the yarn having such a structure, the glass beads or the metal as the reflecting material is almost continuously exposed on a part of the surface of the warp depending on the twisted state.

  The yarn having the phosphorescent material on the surface of the yarn is, for example, using the phosphorescent material-containing polyester raw cotton obtained by shortening the polyester fiber obtained by kneading the phosphorescent material into polyester and melt spinning at the raw material stage, and making a spun yarn, It is preferable to twist the appropriate number of the phosphorescent material-containing spun yarn and the polyester spun yarn and use them as a single yarn because the mechanical properties such as the strength of the entire hose are hardly deteriorated. In the case of the yarn having such a structure, the phosphorescent material is exposed almost continuously on the surface of the warp as a part of the warp according to the twisted state.

  The lining layer made of synthetic resin provided on the inner surface of the jacket 2 is provided on the inner peripheral surface of the jacket by using a resin tube made of urethane resin or vinyl chloride resin, which has been conventionally used. Just do it.
