Description

The present invention relates to a fire-fighting hose in which a lining material is applied to the inner surface of a jacket composed of warp threads arranged in an annular shape and weft threads woven spirally into the warp threads, and the present invention particularly relates to the fire-fighting hose. It relates to a fire hose in which a V-shaped index indicating a retracting direction is partially represented by the weaving of the jacket.

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 the fire extinguishing activities in the building, there are some tragic accidents such as firefighters losing the direction to evacuate and being caught in fire and 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 direction on which the firefighter should evacuate should be indicated on the fire hose. 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 reflective material or luminous. It is displayed with a coating material such as paint, and may disappear when the hose is worn.

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 diagonal weave structure so that the warp threads are dense, by using warp threads and weft threads. In the fire hose, a diagonal weave structure in which the direction of the diagonal line is opposite to the diagonal weave structure is formed in a part of the circumferential direction of the jacket, and one of the normal diagonal pattern and the reverse diagonal pattern is formed. We propose a clear V-shaped index by alternately using colored warp threads and uncolored or differently colored warp threads in the same number of warp threads on both sides from the boundary of the above. did.

However, in this case, since the colored warp threads form a V-shaped index indicating the evacuation direction, when the jacket is worn by dragging the fire hose, the colored warp threads are worn and the color becomes lighter. There was a possibility that the V-shaped index would be unclear.

Japanese Patent No. 4979845 Japanese Unexamined Patent Publication No. 2004-132443 Utility Model Registration No. 309121 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 the V-shaped index is displayed beautifully and clearly. At the same time, the purpose is to prevent the V-shaped index from becoming unclear due to wear.

Therefore, in the present invention, the warp threads arranged in an annular shape and the weft threads woven into the warp threads in a spiral shape are used to form a jacket on the inner surface of the jacket, which is woven by a diagonal weave structure so that the warp threads are densely formed. In a fire-fighting hose with a lining, a diagonal weave structure (hereinafter referred to as a regular diagonal pattern) in which the direction of the diagonal line is opposite to that of the diagonal weave structure (hereinafter referred to as a regular diagonal pattern) in a part of the circumferential direction of the jacket. In the cross-sectional area of the colored warp threads and the colored warp threads, the colored warp threads and the colored warp threads are formed over the same number of warp threads on both sides from one boundary between the normal diagonal pattern and the reverse diagonal pattern. It is characterized in that warp threads that are 5 to 40% thick and are uncolored or colored in another color are used alternately.

In the present invention, the colored warp yarn can be a phosphorescent yarn or a reflective yarn. Further, in the present invention, it is preferable that the jacket is woven from warp threads and weft threads by a 2/1 diagonal weave structure. Further, in the present invention, it is preferable to alternately use the colored warp yarn and the uncolored warp yarn or the warp yarn colored in another color over the entire portion where the inverted diagonal pattern is formed.

Further, in the present invention, reverse diagonal texts are formed at a plurality of locations in the circumferential direction of the jacket, and even at all the reverse diagonal texts, on both sides from one boundary between the normal diagonal text and the reverse diagonal text. It is also possible to alternately use colored warp threads and uncolored or differently colored warp threads in the same number of warp threads.

Schematic diagram schematically showing the structure of the jacket of FIG. Surface view of the jacket in 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, the V-shaped index 4 indicating the retracting direction (right side in FIG. 1) is displayed on the surface of the jacket 2 by the woven structure of the jacket 2.

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 into the warp thread 5. As a whole, it is woven by a 2/1 diagonal weave structure, and the diagonal line 7 rising to the left appears in most of the diagonal weave structure.

In the following description in this specification, the diagonal weave structure in which the upward-sloping diagonal line appears is referred to as a "normal diagonal sentence", and the diagonal weave structure in which the upward-sloping diagonal line appears in the opposite direction. Is referred to as "reverse diagonal sentence".

Therefore, a part of the jacket 2 in the circumferential direction is woven by a 2/1 diagonal weave structure having a reverse diagonal pattern opposite to the diagonal weave structure of the normal diagonal pattern, and the portion of the reverse diagonal pattern. The diagonal lines 8 rising to the right appear in, and the diagonal lines 7 and 8 appear in a mountain shape at the boundaries 9 and 10 between the normal diagonal line and the reverse diagonal line.

Therefore, in the present invention, as shown in FIG. 3, the warp threads 11 and the uncolored warp threads 11 are colored and uncolored on both the left and right sides from the boundary 9 of one of the forward and reverse diagonal sentences, over the same number of warp threads 5. Warp threads 5 and warp threads 5 are used alternately.

In FIG. 3, the warp threads 11 colored are arranged over the entire portion of the reverse diagonal sentence, and the reverse diagonal sentence is located on the normal diagonal sentence side from one boundary 9 of the normal diagonal sentence and the reverse diagonal sentence. The warp threads 11 are colored only in the same number as the warp threads 11 in the part of the warp, but the warp threads 11 are not limited to this configuration and are colored only in a part of the reverse diagonal sentence, which is the reverse of the normal diagonal sentence. It is also possible to use the warp yarns 11 colored in the same number as the warp yarns 11 in the reverse diagonal text portion from one boundary 9 with the diagonal text to the normal diagonal text side.

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, showing a pattern appearing on the surface of the jacket 2 by the colored warp threads 11 and the uncolored warp threads 5. As for the woven structure, FIG. 5 also shows the same structure as that of FIGS. 3 and 4.

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, only the warp threads 5 and 11 are exposed on the surface, and the weft thread 6 is the warp threads 5 and 11. It is configured so that it is hidden by the jacket 2 and not exposed on the surface of the jacket 2.

Therefore, in FIG. 4, the weft thread 6 is largely exposed from 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 covered with the warp threads, 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. In the normal diagonal part, the upward-sloping striped pattern 12 is expressed, and in the reverse diagonal part, the left-upward striped pattern 13 is expressed. Will be expressed.

In the present invention, as shown in FIG. 6, in the portion showing the V-shaped index 4, as the uncolored warp, the warp 14 which is 5 to 40% thicker in cross section than the colored warp 11 is used. ..

For example, when the warp yarn 5 and the colored warp yarn 11 use a yarn obtained by twisting six 200tex yarns, a yarn obtained by twisting seven or eight 200tex yarns as a thick warp 14 is used. It is appropriate to do. 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.

In the above description, all the warp threads other than the colored warp threads 11 are described as uncolored warp threads, but in the portion forming the V-shaped index 4, the warp threads are replaced with the uncolored warp threads. It is also possible to use a warp that is colored in a color different from the color in the colored warp 11.

Further, in the above description, the reverse diagonal pattern is formed only at one place in the circumferential direction of the jacket 2, but the present invention is not limited to this configuration, and the reverse diagonal line is formed at a plurality of places in the circumferential direction of the jacket 2. The V-shaped index 4 can be provided in all the reverse diagonal sentences as in the above description.

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

According to the present invention, symmetrical striped patterns 12 and 13 are formed by the normal diagonal pattern and the inverted diagonal 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.

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 in FIG. 1, the firefighter is naturally guided to the right, that is, toward the terminal connected to the pump by the V-shaped index 4, and is safe. It can be evacuated.

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 colored warp yarn 11, so that the V-shaped index 4 is not obscured by wear or the like.

Further, according to the present invention, in the portion representing the V-shaped index 4, the uncolored warp yarn is thicker than the colored warp yarn 11 and the warp yarn 14 is used, so that this portion is rubbed against the ground and worn. Even in this case, only the uncolored warp threads 14 are worn, the colored warp threads 11 are less likely to be worn, and the V-shaped index 4 is not blurred, so that the warp threads can be evacuated more safely. ..

In particular, when a phosphorescent yarn or a reflective yarn is used as the colored warp yarn 11, these yarns tend to lose their functions due to wear, but in the present invention, there is a thick warp yarn 14 adjacent to the colored warp yarn 11. Therefore, the colored warp yarn 1 is protected by the thick warp yarn 14 and is not worn.
