Description

The present invention relates to a metal-like hose with a metallic appearance that is used, for example, in a shower hose.
Specifically, a metal layer for decoration that shines in a metallic color is provided on the surface of the flexible hose body, a protective layer is laminated on the entire outside, and the metal of the metal layer for decoration passes through this protective layer. The present invention relates to a metal-like hose whose color can be seen from the outside.

  Conventionally, as this type of metal-like hose, for example, a warm stamping sheet made of a metallized layer such as aluminum and an adhesive layer is supported on a carrier sheet, and this warm stamping sheet is attached to a flexible plastic hose. A warm stamping sheet is bonded to the entire circumference of the carrier hose by peeling the carrier sheet after heat-pressing on the surface, and a transparent protective layer (outer hose) is integrated on the warm stamping sheet. (For example, refer patent document 1).

JP-A-8-47982 (page 3-6, Fig. 1-4)

  However, in such a conventional metal-type hose, a warm stamping sheet is bonded to the entire surface of the flexible hose, but the metallized layer made of aluminum or the like and the flexibility are bent or pulled. Since the amount of elongation due to deformation differs greatly, the metallized layer cannot follow the deformation of the flexible hose, and the metallized layer cracks or cracks, and there is hot water between the metallized layer and the hose surface. As a result, the metallized layer peeled off from the surface of the hose body.

The first device of the present invention aims to reliably prevent the occurrence of cracks and cracks in the decorative metal layer.
In addition to the object of the first device, the second device aims to prevent the peeling phenomenon by securely bonding the inner and outer hose bodies and the protective layer.
In addition to the purpose of the first device or the second device, the third device aims to improve the shape retaining performance of the entire hose and prevent creases.

In order to achieve the above-described object, the first of the present inventions is a method in which a strip-shaped decorative metal layer is spirally wound in the hose axial direction along the surface of the hose body, and the decorative metal The layers are arranged with a gap between them, and a protective layer is adhered and laminated on the surface of the hose body and the outside of the decorative metal layer.
The second device is characterized in that, in addition to the structure of the first device, a structure in which a coating film having good adhesion with the material of the hose body and the protective layer is formed around the metal layer for decoration. .
The third device is characterized in that, in addition to the configuration of the first device or the second device, a structure in which a coil made of a hard material is embedded spirally inside the hose body.

The first of the present inventions is that a strip-shaped decorative metal layer is spirally wound in the hose axial direction along the surface of the hose body, and a gap is provided between the decorative metal layers. By arranging and laminating a protective layer in close contact with the surface of the hose body and the outside of the decorative metal layer, the gaps are stretched and deformed due to bending deformation and tensile deformation of the hose body. The decorative metal layer does not deform.
Therefore, it is possible to reliably prevent the occurrence of cracks and cracks in the decorative metal layer.
As a result, there is no risk of the decorative metal layer peeling off from the surface of the hose body, and the metallic shine is prolonged for a long time, compared with the conventional one in which the decorative metal layer is bonded to the entire surface of the flexible hose. Can maintain the high commercial value.

In the second device, in addition to the effect of the first device, the decorative metal layer is formed by coating the hose body and the protective layer with a good adhesive film around the decorative metal layer. Even if the material is non-adhering to the hose body and the protective layer, the hose body and the protective layer are bonded via the coating.
Therefore, the inner and outer hose bodies and the protective layer can be securely bonded to prevent the peeling phenomenon.
As a result, no gap or the like is generated between the hose body and the protective layer, so that intrusion of water or the like can be prevented and stable use can be performed for a long period of time.

In the third device, in addition to the effects of the first device or the second device, a coil made of a hard material is embedded spirally inside the hose body, so that pressure acts in the radial direction of the hose body. Even if it is crushed and deformed, the inner metal layer does not close (kink), and in addition, the deformation of the decorative metal layer is within an allowable range, so that it is not crushed flat.
Accordingly, the shape retention performance of the entire hose can be improved and creases can be prevented.
As a result, the hose does not bend at the same location, so that the hose can be used for a long time without causing a sense of incongruity during use.

  As shown in FIGS. 1 to 4, an embodiment of the metal tone hose A of the present invention includes a flexible hose body 1, a decorative metal layer 2 whose surface is shining in a metallic color, and transparent or semi-finished. It is composed of a transparent protective layer 3, and a strip-shaped decorative metal layer 2 is spirally wound in the hose axial direction along the surface of the hose body 1, and there is a gap between the decorative metal layers 2. The protective layer 3 is disposed in close contact with the surface of the hose body 1 and the outside of the decorative metal layer 2 and is integrated with each other.

  The hose body 1 is formed into a cylindrical shape using, for example, a vinyl chloride resin, a urethane-based resin, or a soft synthetic resin of the same type, and at least in order to make the metal color of the decorative metal layer 2 described later stand out, at least It is preferable to make the outer surface an opaque color such as black.

A plurality of reinforcing yarns 1a are preferably embedded in the inside of the hose body 1 in a net shape.
As the reinforcing yarn 1a, for example, a multifilament knitted from polyester, nylon, aramid fiber or thin monofilament (monofilament), or a monofilament such as olefin resin or polyester resin is used. They are spirally wound along the outer peripheral surface of the inner layer 1b to form a mesh, or are knitted into a cylindrical mesh by knitting or the like, and an intermediate layer 1c is laminated on the outer side to integrate them.
In particular, when a monofilament is used as the reinforcing yarn 1a, the hose body 1 is not easily crushed by the rigidity of the monofilament, and the shape retention performance of the entire hose can be improved.

  Further, in addition to the reinforcing yarn 1a, as shown in FIG. 4, for example, a hard synthetic resin wire such as a thick monofilament (stretched monofilament), a metal wire such as stainless steel, or a coil 1d made of a hard material similar thereto is spirally formed. It is also possible to embed the coil 1d instead of the reinforcing thread 1a.

  In addition, the decorative metal layer 2 is formed in a strip shape from a metal foil such as an aluminum foil or a stainless steel foil, or a similar metal color film or thin plate, and the strip-shaped decorative metal layer 2 is used as the intermediate layer. While being spirally wound in the hose axial direction along the outer peripheral surface of the layer 1c, the spiral gap S is arranged between the decorative metal layers 2.

  A protective layer 3 made of a transparent or translucent soft material is provided as an outer layer on the outer peripheral surface of the intermediate layer 1c and on the outer side of the strip-shaped decorative metal layer 2 covered on a part of the intermediate layer 1c. By laminating the outer peripheral surface of the layer 1c and the outer surface of the decorative metal layer 2 so as to be in close contact with each other without gaps, the metal color of the decorative metal layer 2 can be seen through from the outside through the protective layer 3. ing.

  Here, when the decorative metal layer 2 is made of a material that is non-adhesive to the intermediate layer 1c and the protective layer 3, the intermediate layer 1c and the protective layer 3 are connected to each other as shown in FIG. For example, a vinyl chloride resin, a urethane resin, or a soft synthetic resin of the same kind is coated around the decorative metal layer 2 as a synthetic resin having good adhesion with the material of the coating, and the coating 2a and the intermediate layer are formed. The outer peripheral surface of 1c and the inner peripheral surface of the protective layer 3 are bonded and integrally connected.

Further, when the decorative metal layer 2 is made of a non-adhesive material only with the intermediate layer 1c, the material and the adhesive property of the intermediate layer 1c are good for connecting them together as shown in FIG. It is also possible to bond and fix the decorative metal layer 2 to the intermediate layer 1c by sandwiching the adhesive layer 2b.
Embodiments of the present invention will be described below with reference to the drawings.

  In the first embodiment, as shown in FIG. 1, a plurality of reinforcing yarns 1a are embedded in the inside of the hose body 1 in a net shape, and a decorative metal is provided along the surface of the outer intermediate layer 1c. The layer 2 is spirally wound in the hose axial direction to leave a spiral gap S between the decorative metal layers 2, and the surface of the intermediate layer 1 c exposed in the gap S and the decorative metal layer 2 The protective layer 3 is adhered to each of the surfaces and laminated.

  The coating 2a formed around the decorative metal layer 2 shown in FIG. 2 may be formed of the material of the decorative metal layer 2 and a non-adhesive material.

Next, the effect of the metal tone hose A will be described.
As described above, since the gap S is vacant between the decorative metal layers 2, even if the hose body 1 is bent or pulled, the gap S expands and contracts, so that the belt-like decorative metal layer is formed. Since no bending force or tensile force acts on 2 and it does not deform, cracking and cracking of the decorative metal layer 2 are reliably prevented and not peeled off.

  Furthermore, since a plurality of reinforcing yarns 1a are embedded in the inside of the hose body 1, the hose body 1 is difficult to expand and deform even if the internal pressure of the hose body 1 increases, and the pressure resistance performance can be improved. Even if it is bent and crushed into a flat shape, it is elastically restored, so that it can be used for a long period of time without causing discomfort during use.

  When the decorative metal layer 2 and the coating 2a are formed of a non-adhesive material, the decorative metal layer 2 is displaced due to bending deformation of the hose body 1 or the protective layer 3, and the entire hose There is an advantage of improving the flexibility.

  In Example 2, as shown in FIG. 4, in addition to the reinforcing yarn 1a, a coil 1d made of a hard wire such as a thick monofilament (stretched monofilament) is embedded in the hose body 1 in a spiral shape. Unlike the first embodiment shown in FIGS. 1 to 3, the other configuration is the same as that of the first embodiment shown in FIGS. 1 to 3.

  Accordingly, the second embodiment shown in FIG. 4 also has the same effect as the first embodiment described above, and additionally, the coil 1d made of a hard material is wound, so that the hose is not easily crushed and the shape retention performance is improved. There is an advantage.

In the embodiment shown above, a single decorative metal layer 2 is spirally wound in the hose axial direction along the surface of the hose body 1 to form a spiral between the decorative metal layers 2. The gap S was opened, but the present invention is not limited to this, and two or more decorative metal layers 2 are spirally wound along the surface of the hose body 1 so as to intersect the hose axial direction. A rhombus-shaped gap S is formed between the decorative metal layers 2, and the protective layer 3 is laminated so that the surface of the hose body 1 exposed in the gap S and the surfaces of both the decorative metal layers 2 are in close contact with each other. You may do it.
In this case, the same operation and effect as in the previous embodiment can be obtained.
