Description

The present invention relates to a fire hose in which a lining material is applied to the inner surface of a jacket composed of warp threads arranged in a ring shape and weft threads woven spirally into the warp threads, and a firefighter particularly retracts the hose. The present invention relates to a fire hose and a method for manufacturing the same, in which a V-shaped index indicating a retracting direction is shown on a part of the fire hose by weaving the jacket when the direction to be lost is lost.

Generally, fire hoses are used for fire extinguishing activities in the event of a fire, but in the fire extinguishing activities, firefighters are often caught in smoke and lose their direction. Especially in fire extinguishing activities inside buildings, firefighters have lost the direction to evacuate, which has caused tragic accidents such as being caught in fire and being burned to death.

In order to prevent such an accident, one of the fire hoses that are always present at the fire site is always connected to the fire pump outside the fire site, so the fire hose should indicate the direction in which the firefighter should evacuate. Has been proposed.

For example, Japanese Patent No. 4979845, Japanese Patent Application Laid-Open No. 2004-132443, Utility Model Registration No. 3091291, etc. propose to provide an arrow index on a fire hose, but this arrow index is a reflector or luminous. It is displayed with a coating material such as paint, and may disappear when the hose is worn.

In particular, in these cases, the arrow index drawn in the drawing cannot be formed as a woven structure of the jacket, and it is applied to the surface of the hose with a roller or the like, or by spraying. Inevitably, if the surface of the hose was worn, the arrow index would disappear immediately.

Further, in Japanese Patent No. 6093893 and Japanese Patent No. 6116732, it is proposed that the arrow index is expressed by weaving a jacket. In these cases, they did not disappear due to wear, but the arrow index was unclear and the evacuation direction was difficult to understand.

In view of these circumstances, the applicant has previously made Japanese Patent Application No. 2018-71960 by lining the inner surface of the jacket, which is woven by a twill weave structure so that the warp threads are dense, by using warp threads and weft threads. In the fire hose, a reverse twill weave structure in which the direction of the twill line is opposite to that of the twill weave structure is formed in a part of the circumferential direction of the jacket, and the normal twill pattern and the reverse twill pattern are formed. A clear V-shaped index can be obtained by alternately using dark-colored warp threads and uncolored or another light-colored warp threads in approximately the same number of warp threads from one boundary to both sides. I proposed what was displayed.

However, in this case, the V-shaped index can be sufficiently recognized under bright daytime conditions, but the V-shaped index can be sufficiently recognized under nighttime fires and indoor sunlight-resistant conditions. Is often difficult.

Further, as shown in Japanese Patent No. 4979845, Japanese Patent Application Laid-Open No. 2004-132443, Utility Model Registration No. 3091291, etc., it can be used as an index indicating the evacuation direction with a phosphorescent paint, a reflective material, or the like. If the hose itself becomes invisible in the dark, it may no longer be possible to induce evacuation with only small indicators.

Japanese Patent No. 4979845 Japanese Unexamined Patent Publication No. 2004-132443 Utility Model Registration No. 3091291 Japanese Patent No. 6093893 Japanese Patent No. 6116732

The present invention has been made in view of such circumstances, and a V-shaped index indicating a retracting direction is represented on a part of a fire hose by weaving the jacket, and even at night or in a dark indoor condition. The purpose is to clearly express the existence of the hose itself and to express its V-shaped index beautifully and clearly.

Thus, the invention of the fire hose of the present application is made by weaving a warp yarn arranged in a ring shape and a weft yarn spirally woven into the warp yarn by a twill weave structure so that the warp yarn becomes dense. In a fire hose with a lining on the inner surface of the jacket, the direction of the twill line on a part of the circumferential direction of the jacket is opposite to that of the twill weave structure (hereinafter referred to as "regular twill"). A twill weave structure (hereinafter referred to as "reverse twill") is formed, and the number of warp threads is approximately the same on both sides from one boundary between the normal twill and the reverse twill. It is characterized in that warp threads coated with a paint or reflective paint (hereinafter referred to as phosphorescent paint or the like) and warp threads not coated with the phosphorescent paint or the like are used alternately.

In the present invention, it is preferable to apply the phosphorescent paint or the like to the warp threads of the jacket except for the portion where the warp threads coated with the phosphorescent paint and the like are alternately used.

Further, in the present invention, it is preferable that the jacket is woven with warp threads and weft threads by a 2/1 twill weave structure.

Further, in the present invention, it is preferable to use a warp yarn in the jacket to which the phosphorescent paint or the like is not applied, which is 5 to 40% thicker in cross-sectional area than the warp yarn coated with the phosphorescent paint or the like. Further, the warp yarn to which the phosphorescent paint or the like is not applied is preferably colored in a dark color.

Furthermore, in the present invention, it is preferable to alternately use the warp yarn coated with the phosphorescent paint or the like and the warp yarn not coated with the phosphorescent paint or the like over the entire portion where the inverted diagonal pattern is formed.

Further, in the present invention, reverse diagonal patterns are formed at a plurality of locations in the circumferential direction of the jacket, and warp threads are formed on both sides from one boundary between the normal diagonal pattern and the reverse diagonal pattern at all the reverse diagonal patterns. It is preferable to alternately use the warp threads coated with the phosphorescent paint and the warp threads not coated with the phosphorescent paint, etc., in the same number of threads.

Next, in the method of manufacturing a fire-fighting hose in the present application, a jacket is woven by a twill weave structure so that the warp threads are densely woven by the warp threads arranged in a ring shape and the weft threads woven spirally into the warp threads. In weaving the jacket in the method of manufacturing a fire-fighting hose by lining the inner surface of the jacket, the direction of the twill line is a part of the circumferential direction of the jacket and the twill weave structure (hereinafter, "" It forms a twill weave structure (hereinafter referred to as "reverse twill") that is the opposite of "normal twill"), and warp threads on both sides from one boundary between the normal and reverse twill. Water-repellent warp threads and non-water-repellent warp threads are alternately used over the same number, and then the woven jacket is coated with phosphorescent paint, phosphorescent paint, reflective paint, etc. (hereinafter, phosphorescent). It is characterized by applying a paint or the like) and then lining the inner surface of the jacket.

In the present invention, it is preferable not to apply the water-repellent treatment to the warp of the jacket except for the portion where the water-repellent warp and the non-water-repellent warp are alternately used.

Further, in the present invention, it is preferable that the jacket is woven from warp threads and weft threads by a 2/1 twill weave structure.

Further, it is preferable to use the water-repellent warp yarn in the jacket, which is 5 to 40% thicker in cross-sectional area than the water-repellent warp yarn. Further, it is preferable that the warp yarn subjected to the water-repellent treatment is colored in a dark color.

Further, in the present invention, it is preferable to alternately use the water-repellent warp yarn and the non-water-repellent warp yarn over the entire portion where the inverted diagonal pattern is formed.

Further, in the present invention, reverse diagonal patterns are formed at a plurality of locations in the circumferential direction of the jacket, and warp threads are formed on both sides from one boundary between the normal diagonal pattern and the reverse diagonal pattern at all the reverse diagonal patterns. It is preferable that the water-repellent warp threads and the water-repellent warp threads are alternately used in the same number of threads.

Schematic diagram schematically showing the structure of the jacket of FIG. Surface view of the jacket of FIG. VI-VI sectional view in FIG.

Hereinafter, the present invention will be described with reference to the drawings. FIG. 1 shows a fire hose 1 of the present invention, in which 2 is a jacket, and the inner surface of the jacket 2 is provided with a flexible rubber or plastic lining 3. In the present invention, a V-shaped index 4 indicating the direction in which the firefighter should evacuate (right side in FIG. 1) is displayed on the surface of the jacket 2 by the woven structure of the jacket 2, the phosphorescent paint, or the like. ..

In the present invention, the phosphorescent paint or the like is also applied to a portion other than the V-shaped index 4, and the phosphorescent paint or the like is applied to the entire fire hose 1, and there is no phosphorescent paint or the like. It is preferable that the character index 4 is formed.

By doing so, the entire fire hose 1 emits light or reflects light to attract the attention of firefighters, and while the phosphorescent paint or the like is applied, only the portion of the V-shaped index 4 is phosphorescent. Since no paint or the like is applied, the fire hose 1 is not lost, and the fire hose 1 has a V-shaped index 4 in which the phosphorescent paint or the like is not applied, so that the evacuation direction can be clearly known. is there.

Thus, FIG. 2 shows an organizational chart of the jacket 2 in the present invention, in which the jacket 2 is composed of a warp thread 5 arranged in an annular shape and a weft thread 6 spirally woven with respect to the warp thread 5. , As a whole, it is woven by a 2/1 twill weave structure, and the twill line 7 rising to the left appears in most of the twill weave structure.

In the following description in this specification and drawings, the twill weave structure in which the upward-sloping diagonal line appears is referred to as "regular twill", and the upward-sloping diagonal line appearing in the regular diagonal is "positive". It is called "twill line". In addition, the twill weave structure in which the upward-sloping diagonal line appears in the opposite direction to the normal diagonal sentence is called "reverse twill", and the upward-sloping diagonal line appearing in the reverse diagonal is called "reverse diagonal line". Refer to.

Thus, in this jacket 2, most of the jacket 2 is woven in a normal twill pattern, but a part of the jacket 2 in the circumferential direction has a reverse twill structure opposite to that of the normal twill pattern. It is woven by a 2/1 twill weave structure according to the sentence, and an upward-sloping reverse twill line 8 appears in the reverse twill part, and the boundaries 9 and 10 between the normal twill and the reverse twill. In, the normal diagonal line 7 and the reverse diagonal line 8 appear in a chevron shape.

Therefore, in the present invention, as shown in FIG. 3, a phosphorescent paint or the like is applied to both the left and right sides from the boundary 9 of one of the forward and reverse diagonal sentences in approximately the same number of warp threads 5. The warp threads 5 and the warp threads 11 to which the phosphorescent paint or the like is not applied are used alternately. Although it is not related to the configuration of the present invention, the weft thread 6 may be coated with the phosphorescent paint or the like over the entire circumference of the jacket 2.

In FIG. 3, the warp threads 11 to which the phosphorescent paint or the like is not applied are arranged over the entire portion of the reverse diagonal pattern, and the warp threads 11 are arranged from one boundary 9 of the normal diagonal pattern and the reverse diagonal pattern to the normal diagonal pattern side. Although the warp threads 11 to which the phosphorescent paint or the like is not applied are used in the same number as the warp threads 11 to which the phosphorescent paint or the like is not applied to the reverse oblique pattern portion, the warp threads 11 are not limited to this configuration and are applied only to a part of the reverse oblique pattern. Using warp threads 11 without applying phosphorescent paint or the like, the number of warp threads 11 in the reverse diagonal pattern is almost the same as that of the warp threads 11 from one boundary 9 of the forward diagonal pattern and the reverse diagonal pattern to the normal diagonal pattern side. It is also possible to use the warp yarn 11 without applying the phosphorescent paint or the like.

FIG. 4 is a drawing schematically showing the structure of the jacket 2 shown in FIG. 3 at intervals so that the warp threads 5, 11 and the weft threads 6 can be easily understood, and the weaving structure is exactly the same as that of FIG. Shows the organization of.

FIG. 5 is a surface view of the jacket 2 shown in FIGS. 3 and 4, and is a pattern that appears on the surface of the jacket 2 by the warp threads 5 coated with the phosphorescent paint and the like and the warp threads 11 not coated with the phosphorescent paint and the like. It is a surface view which displayed.

By the way, in general, the fire hose 1 is often used by dragging violently on the ground, and the weft thread 6 of the jacket 2 mainly bears the pressure resistance, so that the weft thread 6 is damaged when the fire hose 1 is dragged. There should be no such thing.

Therefore, in order to prevent the weft 6 from being exposed from the jacket 2, the warp threads 5 and 11 of the jacket 2 are mainly woven so as to be dense, and only the warp threads 5 and 11 are exposed to the surface.

Therefore, in FIG. 4, the weft thread 6 is largely exposed between the warp threads 5 and 11, but in the actual jacket 2, the warp threads 5 and 11 protrude from both sides to the exposed portion of the weft thread 6, and FIG. As shown in the above, the weft thread 6 is hidden by the warp thread, and only the warp threads 5 and 11 cover the surface of the jacket 2.

Therefore, the colored warp threads 11 protrude from both sides of the weft thread 6 and come into contact with each other, and the uncolored warp threads 5 also protrude from both sides of the weft thread 6 and come into contact with each other. The striped pattern of the above is expressed, the striped pattern 12 rising to the right is represented in the part of the forward oblique text, and the striped pattern 13 rising to the left is represented in the portion of the reverse diagonal text. The character index 4 is expressed.

In the present invention, as shown in FIG. 6, in the portion showing the V-shaped index 4, the warp yarn 11 is not coated with the phosphorescent paint or the like, and is 5 to 40% thicker in cross-sectional area than the warp yarn 5 coated with the phosphorescent paint or the like. It is preferable to use.

For example, when the warp yarn 5 coated with a phosphorescent paint or the like uses a yarn obtained by twisting six 200tex yarns, seven or eight 200tex yarns are twisted as a thick warp yarn 11 not coated with a phosphorescent paint or the like. It is appropriate to use a combined thread. When 7 threads are twisted, it is 16.6% thicker than 6 threads, and when 8 threads are twisted, it is 33.3% thicker than 6 threads.

Further, according to the present invention, in the portion representing the V-shaped index 4, the warp yarn 11 to which the phosphorescent paint or the like is not applied uses a yarn thicker than the warp yarn 5 to which the phosphorescent paint or the like is applied, so that this portion is the ground. Even when it is rubbed and worn, only the warp yarn 11 to which the phosphorescent paint or the like is not applied is worn, and the warp yarn 5 to which the phosphorescent paint or the like is applied is less likely to be worn, and the V-shaped index 4 may become unclear. It is possible to evacuate more safely.

In particular, since threads coated with phosphorescent paint or the like are used as the warp threads 5, these threads tend to lose their functions due to wear, but the warp threads 5 coated with phosphorescent paint or the like are used in the portion displaying the V-shaped index 4. Since there is a thick warp yarn 14 to which the phosphorescent paint or the like is not applied adjacent to the yarn, the warp yarn 5 coated with the phosphorescent paint or the like is protected by the thick warp yarn 11, and the clarity of the V-shaped index 4 is not impaired.

Further, in the present invention, it is preferable that the warp yarn 11 to which the phosphorescent paint or the like is not applied is colored in a dark color. Even if the warp threads 11 to which the phosphorescent paint or the like is not applied have the same color as the warp threads 5 to which these are applied, the V-shaped index 4 is clear due to the phosphorescent paint or the like in dark places, but it is rather difficult to see in bright places. Therefore, by coloring the warp yarn 11 in a dark color without applying a phosphorescent paint or the like, the evacuation direction can be clearly recognized without losing sight of the retracting direction even in a bright place.

Further, in the present invention, reverse diagonal texts are formed at a plurality of locations in the circumferential direction of the jacket 2, and at all the reverse diagonal texts, from one boundary 9 of the normal diagonal text and the reverse diagonal text to both sides. It is preferable to alternately use the warp yarns to which the phosphorescent paint or the like is applied and the warp yarns to which the phosphorescent paint or the like is not applied, in approximately the same number of the warp yarns 5 and 11.

By doing so, even if the fire hose 1 is twisted, any V-shaped index 4 is always in the view of the firefighter, so that the evacuation direction of the firefighter can always be indicated, which is safe. ..

According to the present invention, symmetrical striped patterns 12 and 13 are formed by the normal oblique pattern and the inverted oblique pattern, and the striped patterns 12 and 13 form a beautiful and clear symmetrical V-shaped index as shown in FIG. 4 can be expressed, and the firefighter can know the evacuation direction at a glance, and can safely evacuate.

In FIG. 1, if the right side of the fire hose 1 is connected to the fire pump and the left side is connected to the tip of the cylinder, even if the firefighter is caught in a fire at the fire site, the firefighter can use the V-shaped index 4 to perform the firefighter. It is naturally guided to the right, that is, toward the terminal connected to the pump, and can be safely evacuated from the fire site.

Further, according to the present invention, the V-shaped index 4 is represented by the weaving of the jacket 2, and is represented by the warp yarn 11 coated with the phosphorescent paint or the like, so that the V-shaped index 4 becomes invisible due to wear or the like. Never.

Next, the method for manufacturing the fire hose of the present invention will be described.
In the present invention, when weaving the jacket 2 of the fire hose 1, the warp yarn to be the warp yarn 11 which is not coated with the phosphorescent paint or the like in the jacket 2 of the fire hose 1 is subjected to a water repellent treatment, and the slant Water-repellent warp threads 11 and non-water-repellent warp threads 5 alternate with almost the same number of warp threads 5 and 11 on both sides from one boundary 9 of the sentence and the inverted diagonal sentence. Used for.

After that, the jacket 2 woven in this way is immersed in an aqueous solution or emulsion containing an appropriate phosphorescent paint or the like, and the entire jacket 2 is impregnated with the phosphorescent paint or the like and applied.

At this time, since the water-repellent warp yarn 11 does not repel an aqueous solution or emulsion such as a phosphorescent paint and does not adhere to the warp yarn 11, the phosphorescent paint or the like adheres to the entire jacket 2 and emits light. Only the warp yarn 11 that has been subjected to the water-repellent treatment according to the index 4 repels the phosphorescent paint and the like and does not adhere.

Therefore, the entire hose emits light from the phosphorescent paint or the like, and only the warp thread 11 which has been subjected to the water-repellent treatment repels the phosphorescent paint or the like and does not emit light, so that a clear V-shaped index 4 by the phosphorescent paint or the like is displayed. It is.

After that, the inner surface of the jacket 2 is lined with a lining 3 to form a fire hose 1. Since various methods are known for applying the lining 3 to the jacket 2, any appropriate method may be adopted.

Therefore, according to the present invention, as shown in the fire hose 1 of the present invention, the entire fire hose 1 emits light or reflects light to attract the attention of firefighters, and the phosphorescent paint or the like is applied. Since only the portion of the V-shaped index 4 is not coated with the phosphorescent paint or the like, the V-shaped index 4 is clearly shown.

Therefore, the firefighter does not lose sight of the fire hose 1, and the fire hose 1 has a V-shaped index 4 in which the phosphorescent paint or the like is not applied, so that the evacuation direction can be clearly known and the firefighter is guided to the evacuation direction. is there.
