Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a synthetic resin hose that is used by being attached to a water faucet or the like.

[Prior art and its problems]

Conventionally, this type of synthetic resin hose has been formed by extrusion molding, but all of them are made of synthetic resin of a single color such as blue, so there is little variation, and there is no design effect at all, which reduces the commercial value. In addition, although hoses are generally made of vinyl chloride resin and are flexible, they are subject to excessive tension and compression due to frequent bending during long-term use, causing partial cracks. There was a problem.

In addition, in order to prevent such cracks, there are hoses that have thin metal wires in the synthetic resin layer, but the thin metal wires do not have much flexibility or adaptability to bending, and the synthetic resin layer does not move in the inside or outside direction. There is a risk of biting in and causing partial destruction, and there is also a risk of breakage due to bending fatigue.Furthermore, the appearance is simple and, similarly to the above, no improvement in commercial value can be expected.

The present invention provides a synthetic resin hose aimed at eliminating such problems.

[Means for solving problems]

In order to achieve the above object, the synthetic resin hose of the present invention has a transparent synthetic resin inner layer 1a whose surface is formed into a continuous wave-shaped cross section in the circumferential direction, as shown in the drawings corresponding to the embodiments. A synthetic resin outer layer 1b is integrally layered to form a hose main body 1, and colored fiber threads made of natural fibers or synthetic fibers are attached to each trough of the corrugated surface 3 of the transparent synthetic resin outer layer 1b of the hose main body 1. It has a structure in which strips 2, 2...2 are embedded in the length direction of the hose main body 1.

[Effect]

Since the transparent synthetic resin outer layer 1b in which a plurality of colored fiber threads 2 are embedded is layered on the opaque synthetic resin inner layer 1a, the colored fiber threads 2 appear to be floating from the outside and are beautiful. exhibit an appearance.

Furthermore, since the yarn 2 embedded in the length direction of the hose main body 1 is made of natural fiber or synthetic fiber yarn,
Unlike thin metal wires, it adapts well to the bending of the synthetic resin hose main body 1, and moderately suppresses excessive elongation to prevent partial cracking of the hose.

In addition, the surface of the transparent synthetic resin outer layer 1b is formed into a continuous wave-shaped cross section in the circumferential direction, and colored fiber threads 2, 2, . Since it is buried, the colored fiber threads 2 buried in the troughs will not be worn out because the high portions of the corrugated surfaces 3 will come into sliding contact with other objects.

〔Example〕

The embodiments of the present invention will be explained with reference to the drawings: 1
The main body of the hose is made of vinyl chloride resin, and the inner layer is a white opaque synthetic resin layer 1a, and the opaque synthetic resin inner layer 1a has a colorless transparent synthetic resin outer layer 1b whose surface is formed in a continuous wave-shaped cross section in the circumferential direction. It is made by layering them together.

Reference numeral 2 denotes colored fiber threads made of natural or synthetic fibers, and a plurality of these fiber threads 2 of different colors are attached to the transparent synthetic resin outer layer 1 of the hose main body 1.
The hose body 1 is embedded within each valley portion of the corrugated surface 3 along the entire length of the hose main body 1.

When the hose main body 1 is formed by extrusion molding, these fiber threads 2 are attached to and pushed into the transparent synthetic resin outer layer 1b, so that the length of the hose main body 1 is attached to the surface layer of the synthetic resin outer layer 1b. By embedding the fiber threads 2 by this pushing, the surface of the transparent synthetic resin outer layer 1b is formed into a continuous wave-shaped cross section in the circumferential direction, and each of the wave-shaped surfaces 3 is The colored fiber threads 2 are embedded in the valleys.

Note that the colored fiber threads 2 buried in the valleys of the transparent synthetic resin outer layer 1b do not all need to be of different colors, and several threads of the same color may be embedded.

[Effect of idea]

As described above, according to the synthetic resin hose of the present invention, since the transparent synthetic resin outer layer 1b in which a plurality of colored fiber threads 2 are embedded is layered on the opaque synthetic resin inner layer 1a, it can be colored from the outside. The fiber threads 2 appear to be floating, giving a beautiful appearance, which not only has a great design effect but also significantly improves the commercial value.Furthermore, the length of the hose main body 1 The yarn 2 buried in the direction is made of natural fiber or synthetic fiber yarn, so unlike fine metal wire, it adapts well to the bending of the synthetic resin hose main body 1 and moderately suppresses excessive elongation, making it possible to create a partial hose. This prevents cracks and can withstand long-term use.

Furthermore, since the surface of the transparent synthetic resin outer layer 1b is formed into a continuous wave-shaped cross section in the circumferential direction, when gripping the hose main body 1 wet with water, it is less likely to slip, which makes handling easier. , colored fiber threads 2, 2...2 are buried in each valley of the corrugated surface 3 in the length direction of the hose main body 1, so that the high portions of the corrugated surface 3 come into sliding contact with other objects. The colored fiber threads 2 embedded in the troughs do not wear out and can maintain the above effect for a long period of time.
