JP6244155B2 - Shaped hose for fire hydrant with reflection and phosphorescence - Google Patents

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 phosphorescence 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 alone 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 retaining hose having a small inner diameter of about 18 to 41 mm, after forming the hose, an ink paint (phosphorescent paint) containing a reflective material or the like is successfully applied to a desired location. This was difficult, and there were problems in terms of productivity and manufacturing cost.

Make the (front door) part transparent, or install a light emitter that always emits light in the fire hydrant box, or guide the light of the indicator light that is attached to the fire hydrant and is always lit in the fire hydrant box In an emergency such as the occurrence of a fire, etc., even in the dark, the location and storage state of the hose when stored in the fire hydrant facility can be easily determined by the light emitted from the phosphorescent material and the reflected light from the projected light. Can be recognized. Furthermore, even when the hose is pulled out from the fire hydrant and used, a part of the hose emits light over its entire length and reflects off the projected light, so that the position of the hose and the hose line can be easily confirmed. It is easy to recognize the return path (retreat) to the vicinity of the fire hydrant.

  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 and shape of a fire hydrant holding hose 1 having reflection and phosphorescence according to the present invention is a jacket of a warp and a weft made of synthetic fibers woven in a cylindrical shape. A shape-holding hose for a fire hydrant having a lining layer made of a synthetic resin on the inner side surface and having an inner diameter of 18 to 41 mm, and one reflector line region Z1 extending in the hose length direction on the surface of the jacket And one phosphorescent material line region Z2 extending in the hose length direction is formed, and on the transverse cross section of the shape retaining hose, the reflector line region Z1 and the phosphorescent material line region Z2 are respectively It is characterized by being formed satisfying the central angle (degrees) shown in the following equations (a) and (b).

90 ≦ θ1 ≦ 180 Formula (a)
90 ≦ θ2 ≦ 180 Formula (b)
Here, θ1 (degree) is the central angle of the reflector line region Z1, and θ2 (degree) is the central angle of the phosphorescent material line region Z2.

  The fire hydrant shape retaining hose 1 having reflection and phosphorescence properties according to the present invention is a cylindrical shape without being flattened as a shape retaining hose 1 as 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. 3, 11 is a fire hydrant valve, and 12 is a shape retaining hose nozzle that serves as a water tip when water is discharged. 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. 3, for convenience of explanation, the lid portion (front door) of the fire hydrant box that normally exists is not drawn, but the inside is drawn with the lid portion (front door) removed.

  The shape-keeping hose for a fire hydrant according to the present invention having a reflective / light-accumulating property has one reflector line region Z1 extending in the hose length direction on the surface of the jacket 2 and one extending in the hose length direction. Since the phosphorescent material line region Z2 is formed with the above-mentioned central angles θ (θ1, θ2), both lines exhibit their possession functions even when light is irradiated from only one direction. Sufficient light irradiation can be received, at least partially.

  That is, for example, if light irradiation from the direction A in FIG. 2 is received, both lines receive light irradiation almost equally. In addition, when light irradiation from the direction B in FIG. 2 is received, the phosphorescent material line mainly receives light irradiation, but since the hose is a shape retaining hose, it is stored in the fire hydrant box while maintaining the cylindrical shape. When it is done, it always exhibits a twisted state, so that it is partially irradiated with light when viewed in the entire length direction of the hose, and therefore both lines are irradiated with light.

  In the present invention, it is important that the reflective material line region Z1 and the phosphorescent material line region Z2 are formed one by one, and the fire hydrant shape retaining hose of the present invention is not large in diameter, so it is somewhat thick. Providing each one with a width is important to achieve higher visibility.

Here, as shown in FIGS. 1 and 2, the “reflecting material line region Z1” means that the reflecting material has a width and forms the reflecting material line 4 in the region Z1. its reflector has actually reaches from one end of the formation to that line to another end side end portion, and refers to the entire area which cross section extends the hose longitudinally arcuate, circular arc Corresponds to the central angle θ1 shown in FIG.

Similarly, as shown in FIG. 1 and FIG. 2 for the “luminescent material line region Z2”, the phosphorescent material has a width and forms the phosphorescent material line 5 in the region Z2. the phosphorescent material is actually reaches from one end of the formation to that line to another end side end portion, and refers to the entire area which cross section extends the hose longitudinally arcuate, circular arc Corresponds to the central angle θ2 shown in FIG.

  A more preferable range of the central angle θ (θ1, θ2) is 100 ° or more and 150 ° or less for both θ1 and θ2, as comprehensively determined from the viewpoints of visibility, handling, and manufacturing cost. The central angle θ1 and the central angle θ2 do not have to be the same, and may differ in magnitude.

  In the one region, it is preferable that each line is formed by the presence of a reflective material or a phosphorescent material over the entire surface, but it is not necessarily present over the entire surface from the viewpoint of handling, manufacturing cost, etc. It is not necessary to have a part in the hose length direction and / or the hose circumferential direction, and a part of the whole part is formed in the one region.

  That is, both the reflective material line region Z1 and the phosphorescent material line region Z2 are preferably formed with a reflective material or a phosphorescent material on the entire surface thereof to form one thick line as a whole. Both or one of them may form a plurality of reflecting material lines or phosphorescent material lines. That is the mode shown in the above (2) to (5).

  As shown in FIG. 2, the position where the reflecting material line region Z1 and the phosphorescent material line region Z2 are arranged is preferably a point-symmetrical position with the center point C of the hose cross section as a symmetric point. This is because both areas can reliably receive light irradiation. However, even in that case, one of the circumferential widths of the regions Z1 and Z2 may be larger and the other may be smaller.

The fire hydrant shape retaining hose having reflection and phosphorescence properties according to the present invention is always stored in the fire hydrant box 10 so that the line 5 of the phosphorescent material can function effectively. It is important to configure the fire hydrant equipment such that the material line 5 is exposed to light to some extent. For that purpose, conventional fire hydrant equipment is generally 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 5 is configured to be exposed to light.
Or
(2) It is configured so that the light of the hydrant indicating lamp that is always turned on to indicate the location of the hydrant reaches the inside of the hydrant box, and is configured so that the light storage material line 5 is always exposed to light.
Or
(3) A dedicated 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 5;
It is important to adopt one or a combination of such means.

  In addition, the reflective material line 4 of the fire hydrant shape retaining hose 1 having reflection and phosphorescence properties according to the present invention reflects the light when the shape retaining hose 1 is irradiated with light, and the state and position of the hose. Etc. can be notified to fire fighters. Preferably, a retroreflection is performed.

  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 the light irradiation in the fire hydrant box while keeping the cross section cylindrical as a shape retaining hose, the width of the phosphorescent material line and thus the width of the phosphorescent material line region Z2 is Larger is preferable.

  For the same reason, the reflecting material line 4 is effectively irradiated with light after being pulled out of the fire hydrant box or inside the fire hydrant box while keeping the cross section cylindrical as a shape retaining hose. In order to exhibit, it is preferable that the width of the phosphorescent material line and hence the phosphorescent material line region Z1 is large.

  However, since the shape retaining hose for a fire hydrant is originally not so large in diameter, it is advantageous to provide a single region rather than a plurality of regions.

  In the present invention, the inner diameter of the hose is also determined as a fire hydrant facility. In the present invention, it is preferable that the hose has a diameter of 18 mm or more and 41 mm or less in that a good effect can be obtained.

  In order to form the reflective material line 4 and the phosphorescent material line 5, the coating material containing the reflective material is applied, the coating material containing the luminous material is applied, or the reflective material is provided on the surface of the yarn. It can be formed by adopting means such as weaving a jacket using a warp having a warp and a phosphorescent material on the yarn surface.

  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.

  When using a warp having a reflective material or phosphorescent material on the surface of the yarn, a slit yarn obtained by thinly slitting at least the surface of the resin film provided with a layer of reflective material or a layer of phosphorescent material Etc. can be used.

  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 them as warp yarns because they hardly degrade the 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 warp having a phosphorescent material on the yarn surface is, for example, using a phosphorescent material-containing polyester raw cotton obtained by shortening a 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 phosphorescent material-containing spun yarns and polyester spun yarns and use them as a single warp, since 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 3 made of a synthetic resin provided on the inner surface of the jacket 2 is attached to the inner peripheral surface of the jacket using a resin tube made of urethane resin or vinyl chloride resin, which has been conventionally used. What is necessary is just to provide.

1: Shape retention hose 2: Jacket 3: Liner layer 4: Reflector line 5: Luminescent material line 10: Fire hydrant box 11: Fire hydrant valve 12: Shape retention hose nozzle 13: Hose storage support rod Z1: Reflector line area Z2 : Phosphorescent material line region θ1: central angle of reflector line region θ2: central angle of phosphorescent material line region C: center point of hose cross section
