Abstract

PURPOSE:To improve seasonproofness and pressureproofness and reduce weight by using a wire rod of synthetic resin or the like, forming a coil unit into a spiral shape having a prescribed pitch, organizing a coil unit surface with a plurality of fiber cards, and forming a blade in a circumferential surface total unit of the coil unit. CONSTITUTION:A wire rod 30 of hard synthetic resin is spirally formed by a prescribed pitch, and a coil unit 3 is molded. The wire rods 30, 30 of this coil unit 3 are organized with fiber cords 4, to form a blade 2 in a circumferential surface total unit of the coil unit 3. A cylinder unit 1 is provided in the inside to constitute a jacket hose 20. Thus by constituting the blade 2 with the hard synthetic resin-made coil unit 3 serving as a forming core, a reinforcing function is strengthened to the cylinder unit 1 provided in the inside. Accordingly, by forming the blade of the fiber cords such as by traversing the synthetic resin-made wire rod by a prescribed pitch on the spiral-shaped coil unit as a blade core material, since the jacket hose is constituted by lining forming the cylinder unit of rubber material as a hose material in this blade, the hose, in addition to excellence in pressureproof and weatherproof, is flexible though lightening weight.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a jacket hose, and more particularly, to a flexible hose composed of a flexible inner tube and a reinforcing layer of the tube, and more particularly, to a reinforcing layer. The present invention relates to a jacket hose, which is formed as a braid formed by coiling a synthetic resin wire into a coil core and a fiber thread.

[0002]

2. Description of the Related Art As shown in FIG. 5, a conventional braided hose is a braided hose in which a surface of a rubber or synthetic resin hose 1'is braided with a plurality of knitting yarns 21 'and 22' to cover a braid 2 '. 10 'had been formed.

As shown in FIG. 6, a reinforced blade hose 20 'in which the surface of the blade 2'is vulcanized with rubber or a synthetic resin material is known.

[0004]

Although the conventional blade hose 10 'shown in FIG. 5 is lightweight and has a flexible function,
There is a problem in weather resistance and pressure resistance, and since the reinforced blade hose 20 'shown in FIG. 6 is bulky due to its weight, not only the places to be used are limited, but also it is expensive due to the multiple manufacturing process. there were.

[0005]

The basic structure of the jacket hose according to the present invention will be described below with reference to FIG. In FIG. 1, reference numeral 10 is a jacket hose of the present invention, and the hose 10 is composed of one cylindrical body and two blades.

The cylindrical body 1 is made of a flexible material such as rubber or synthetic resin. The blade 2 has a structure in which a wire body 30 made of a hard synthetic resin material is formed into a spiral shape having a predetermined pitch, and the entire circumferential surface of the coil body is braided on the surface of a coil body 3 with a plurality of fiber threads 4 and 4. Has been done. (Refer to FIG. 2 for the coil body 3)

As is clear from the display of the portion below the center line in FIG. 1, the non-braided portion 31 'of the fiber yarn 4 is shown in the alternating portion of the wire 20 forming the coil body 3.

[0008]

As shown in FIG. 1, the jacket hose of the present invention has a coil body 3 formed by spirally forming a wire rod 20 made of a hard synthetic resin material as a core for forming a blade 2. The reinforcing function for the existing cylindrical body 1 becomes extremely strong as compared with the conventional blade formed of fiber yarn or knitted cloth, and since the coil body is used as the core material of the blade, it has a bending function as a hose. There is no loss.

[0009]

FIG. 3 shows an embodiment of the jacket hose according to the present invention. This embodiment is formed with a predetermined pitch. A spiral coiled fiber coil body 5 formed by a bundle of fibers 40 between the wire rod of the coil body and the wire rods 30, 30.
This is intended to eliminate the gap between the coil body forming wire rods during the braid of the blade.

As is apparent from FIG. 3, the fiber threads 4 and 4 forming the blade 2 are the coil body 3 which is the core material of the blade.
Even if the pitch is large, the fiber coil body 5 is present in the coil body, and the fiber coil body 5 is also braided with the fiber yarns 4 and 4, so that It does not cause pressure irregularity (contact area).

The jacket hose shown in this embodiment is
A cylindrical body whose surface is coated with an adhesive is inserted into a blade cylindrical body in which a blade is applied to the coil body and the fiber coil body, and the cylindrical body surface is filled with a high-temperature pressure air flow. Is integrally formed on the inner surface of the blade cylinder.

A twill weave is the most preferable braid braid, and a known fiber technique such as plain weave can be adopted. In addition, the outer surface may be optionally provided by coating the surface of the jacket hose shown in the above embodiment with rubber or other vulcanizing material.

The jacket hose according to the present invention is not limited to the above embodiment, and as shown in FIG. 4, the coil body 3, the wire rod 30 of the fiber coil body and the fiber bundle 40 are paired (2). It is also possible to form a blade in a twill weave as individual pieces).

Although not shown in particular, a plurality of fiber coil bodies are interposed in the spiral coil body which is the core material of the blade to narrow the exposed surface of the gap portion between the pitches of the coil body. It is also possible to make it optional.

[0015]

Industrial Applicability According to the present invention, a spiral-shaped coil body made of a synthetic resin wire material is used as a core material of a blade with a predetermined pitch, and a fiber thread is woven or braided into the coil body to form a blade. The jacket hose is made by lining a cylindrical body made of a rubber material, which is the material of the hose, inside this blade to form a jacket hose, which has excellent pressure resistance or weather resistance, is lightweight and flexible, and is used when used as an automobile part. Has an excellent function of preventing vibration damage, and also has flexibility, which makes it easy to work on shaped pipes.
