Description

  The present invention relates to a coated wire obtained by twisting and covering a metal wire, and used as a connecting wire, a wire lock, or a wire for decoration or decoration.

For coated wires to be used as wires for wire locks, conventionally, the outer surface of twisted wires is covered with a transparent colored resin layer, and the ground color of the wire can be seen through the resin layer It is disclosed (for example, see Patent Document 1).
In addition, the outer periphery of the wire main body formed by twisting metal wires is coated with an appropriate base material, and a pattern sheet with an arbitrary pattern is bonded to the outer periphery of the base material, and the outer periphery of the pattern sheet is further transparent A resin material that is covered with a resin material so that the pattern can be seen from the outside through the resin material is disclosed (see, for example, Patent Document 2).

Japanese Patent No. 2829138 JP 2004-225163 A

  However, when the outer surface of the twisted wire is directly covered with a transparent colored resin layer as in the former, water resistance or weather resistance is lacking, such as rainwater entering and rusting. In the latter case, when the pattern sheets are laminated together, the sheets are displaced, or the sheet becomes wrinkled with the wire bent, and the appearance is lacking.

  In addition, this type of coated wire has a thick metal wire inside, and the appearance of high-strength material with excellent breaking strength is enhanced, while the texture is enhanced. The handling and storage properties are lacking, such as an increase in weight. Further, the stranded wire 1 (wire rope) of the metal wire is relatively expensive per se, so that the higher the rigidity of the stranded wire 1, the higher the cost.

  Therefore, the present invention is a coated wire that is relatively excellent in water resistance and weather resistance, has a good appearance, has a high-strength material with excellent breaking strength, and is relatively easy to handle and store. Is to be provided at a low cost.

In order to solve the above problems, the present invention adopts the following configurations (1) to (5).
(1) The covered wire of the present invention includes at least a stranded wire 1 formed by twisting a plurality of metal wires, and an inner covering layer 2 made of a light-transmitting elastic resin material that covers the entire circumference of the stranded wire 1; A covered wire composed of an outer covering layer 3 made of a light-transmitting elastic resin material covering the entire circumference of the inner covering layer 2;
The inner covering layer 2 is closely formed along the outer shape of the stranded wire 1 without gaps, and the outer covering layer 3 is closely formed along the outer shape of the inner covering layer 2 without gaps. The projected image 1I of the outer shape of the stranded wire 1 is enlarged and projected onto the outer surface of the outer covering layer 3 by each lens effect of the outer covering layer 3.
(2) In the coated wire, the inner coating layer 2 and the outer coating layer 3 are both based on the same light-transmitting resin, and
The inner coating layer 2 is made of a resin containing colored fluorescent pigments, phosphorescent pigments or light reflecting materials 21 and 22 inside the resin or inside the resin, so that the inner coating layer 2 is light different from the outer coating layer 3. It preferably has a refractive function.
(3) In any one of the above-described coated wires, a printed layer 4 including characters or patterns is fixedly formed on a part or the whole of the resin surface of the inner coated layer 2, and the outer coated is formed on the fixed surface of the printed layer 4 It is preferable that the layer 3 is formed in close contact, and the projected image 1I of the outer shape of the stranded wire 1 is enlarged and projected onto the outer surface of the outer covering layer 3 through the fixing surface of the printing layer 4 or through the fixing surface. .
(4) In any one of the above-described covered wires, the stranded wire 1 is formed by twisting a plurality of strands 11 made of a plurality of metal wires, and the inner covering layer 2 is formed by a double twist configuration. It is preferable to perform close contact molding along the externally exposed shape of each of the strands 11.
(5) In any one of the above-described covered wires, the inner covering layer 2 is extruded in a predetermined first axial cross-sectional shape along the wire length direction, and the first axial cross-sectional shape is the center of the cross section It consists of a polygon or a polygon having a plurality of valley-shaped parts where adjacent sides intersect in a valley shape when viewed from the side,
Further, the outer covering layer 3 is formed by extrusion molding with a predetermined second axial cross-sectional shape different from the first polygonal cross-section along the wire length direction, and the second axial cross-sectional shape is circular, polygonal Or a polygonal shape.

According to the said structure, by forming the strand wire 1 with a comparatively thin or few metal wire material, a flexibility becomes large and a deformation | transformation freedom degree increases. Also, by forming a double coating layer made of a light-transmitting elastic resin material, the flexibility of the entire coated wire is increased, and the reaction force when bent or twisted is only relatively soft. Therefore, the protection performance such as the ability to prevent water from entering the stranded wire 1 is improved, and the water resistance is excellent. As a result, the stranded wire 1 is also resistant to rust and has excellent weather resistance. Furthermore, since the two light-transmitting resin layers have a double lens effect, the internal stranded wire 1 is enlarged and projected on the wire surface, which is thicker than the actual stranded wire 1 and has a high-class appearance. Will be presented. For this reason, even if the stranded wire 1 is relatively thin and inexpensively formed, the texture is not inferior. Rather, the transmissively projected stranded wire 1 and the double coating provide an excellent appearance in texture.

Moreover, the inner coating layer 2 and the outer coating layer 3 have the same light-transmitting resin as the main agent, so that the interlayer adhesion is excellent, and the light transmittance to the outer surface of the wire is improved after repeated bending deformation and torsional deformation. It can be maintained well. Further, the inner coating layer 2 includes a colored fluorescent pigment, a phosphorescent pigment or a light reflecting material on the resin surface or inside the resin, so that the transmitted light is internally diffused or surface refracted, and is distinguished from the lens effect of each layer. It will have a high appearance.

In addition, since the printing layer 4 is fixedly formed on the surface of the inner coating layer 2, characters and patterns can be formed without interposing a sheet or the like between the inner coating layer 2 and the outer coating layer 3. Since the characters and patterns of the printing layer 4 are protected by the outer covering layer 3, blurring due to external rubbing hardly occurs and the long-term display property is excellent.

In addition, since the stranded wire 1 is formed by double twisting with the multiple strands 11, the outer surface area of the stranded wire 1, that is, the contact surface with the inner coating layer 2 can be ensured to be relatively large. Thereby, the fixability of the inner coating layer 2 is improved, and the layer thickness in the radial direction of the inner coating layer 2 is changed, and the lens effect is excellent. For example, in the double twisted configuration of the seven twisted strands 11 as shown in FIG. 1 and FIG. 6, the radial thickness of the inner coating layer 2 in the contact portion of each strand 11 becomes a thick portion in the axial cross sectional view. Moreover, the radial thickness of the inner resin layer at the central top portion of each strand 11 is a thin-walled portion. Such a difference in the radial thickness of the inner coating layer 2 increases the lens effect as shown in FIG.

Further, by configuring the inner coating layer 2 and the outer coating layer 3 with different axial cross-sectional shapes, for example, as shown in FIG. 6, the photorefractive effect of each layer is different, and the lens effect of the wire internal configuration is increased. The Further, as shown in FIGS. 7 (a) and 7 (b), for example, the axial cross section of the inner covering layer 2 has a cross-sectional shape having a valley portion that enters toward the center of the cross section. The thick portions having a relatively large radial thickness and the thin portions having a relatively small radial thickness can be alternately formed. Such a difference in the radial thickness of the inner coating layer 2 increases the lens effect as shown in FIG. The fixability of each layer is improved, and the in-plane projection image of the valley side is refracted and the projection image can be distorted.

  The present invention takes the above-mentioned means, and by applying at least a double elastic resin coating layer, the metal stranded wire is not easily rusted, and therefore it is relatively excellent in water resistance and weather resistance. In addition, it has a good appearance and has a high-strength material with an excellent breaking strength, and the elasticity of the wire is improved by coating with an elastic resin. Will be provided to.

As the best mode for carrying out the present invention, Example 1 (FIGS. 1 to 3 and 6), Example 2 (FIGS. 2 and 4), Example 3 (FIGS. 2 and 5), Example 4 to 6 (FIGS. 7A to 7C), and FIG. 7 will be described together with the drawings shown as Example 7 (FIGS. 8 to 10). In any of the embodiments, the bag of the present invention is such that the coated wire of the present invention includes at least a twisted wire 1 formed by twisting a plurality of metal wires, and a light-transmitting elastic resin that covers the entire circumference of the twisted wire 1. A covered wire composed of an inner covering layer 2 made of a material and an outer covering layer 3 made of a light-transmitting elastic resin material covering the entire circumference of the inner covering layer 2;
The inner covering layer 2 is closely formed along the outer shape of the stranded wire 1 without gaps, and the outer covering layer 3 is closely formed along the outer shape of the inner covering layer 2 without gaps. By the lens effect of the outer covering layer 3, the internal structure of the covering wire including the outer shape of the stranded wire 1 is enlarged and projected on the outer surface of the outer covering layer 3 as projection images 1I and 2I.

Here, “inner covering layer 2” in the present invention means a layer inside the wire in contact with the stranded wire 1, and “outer covering layer 3” means an outer layer of the wire that is finally projected by a lens. No matter how many layers (for example, a printing layer 4 described later) are interposed between the inner layer 2 and the outer layer 3, it is sufficient that at least the inner layer 2 and the outer layer 3 exhibit the lens effect. Hereinafter, the configuration of each embodiment will be described in detail.

  The covered wire of Example 1 shown in FIG. 1 to FIG. 3 and FIG. 6 was closely formed along the outer shape of the twisted wire 1 consisting of a double twist of 7 strands and the twisted strand 1 of the twisted wire 1, An inner covering layer 2 having a true axial cross-sectional shape (first axial cross-sectional shape), and an axial cross-sectional shape (second axial cross-sectional shape) formed in close contact along the circular outer shape of the inner covering layer 2 And an outer coating layer 3 having a perfect circle. Light is transmitted through each layer, and the internal structure of the wire including the outer shape of the stranded wire 1 can be visually recognized from the outside, and the outer coating layer 3 is formed by the lens effects of the inner coating layer 2 and the outer coating layer 3. The projected image 1I of the stranded wire 1 enlarged from the actual diameter and the projected image 2I of the inner coating layer 2 enlarged from the actual diameter are transmitted through and projected onto the outer surface of FIG. ).

(Stranded wire 1)
The stranded wire 1 of Example 1 has a multi-layered twisted structure in which seven strands 11 are twisted in parallel in a feeler type, and the strands of the metal wire constituting each strand 11 are also twisted in parallel in the feeler type. Become. In the present invention, the twisting method is not questioned, and a crossing type, a Warrington type, a seal type, or a combination thereof may be used. Moreover, the constituent wire of each strand 11 should just contain a metal wire in at least one part, for example, the mixed twist which mixed synthetic resin wires, such as a polypropylene, may be sufficient as it. Since the stranded wire 1 is covered twice in the covered wire, the metal wire uses a bare rope that has not been subjected to an external decoration process such as plating. However, the present invention is not limited to this.

(Inner coating layer 2)
The inner coating layer 2 of Example 1 is made of a light-transmitting single resin containing a fluorescent coloring pigment, and is extruded with a circular first axial cross-sectional shape having a diameter twice or more the representative diameter of the stranded wire 1. Is done. The inner coating layer 2 is formed in close contact along the externally exposed shape of each of the strands 11 that are composed of multiple twists, using a light-transmitting elastic resin material as a main ingredient. Thereby, along the circumferential direction of the inner coating layer 2, thick portions 20R1 having a relatively large radial thickness and relatively thin portions 20R2 along the radial direction are alternately formed. The inner covering layer 2 has a lens effect due to a change in the radial layer thickness, as well as a lens effect due to its own circular outer shape. As a result, the projected image of the stranded wire 1 projected onto the outer surface of the inner coating layer 2 is also an enlarged display image that is distorted and projected with respect to the actual shape of the stranded wire 1 (FIG. 1). Specifically, as shown in FIG. 6, the first transmitted light 11 along the outer shape of the stranded wire 1 is largely refracted outward by the lens effect of the inner coating layer 2.

The resin material constituting the inner coating layer 2 of Example 1 includes a fluorescent coloring pigment, but may alternatively or together contain a phosphorescent pigment, or may be formed by transparent coloring with a non-fluorescent pigment. Examples of the main component resin include polypropylene, polyethylene, polyethylene terephthalate (PET), and polybutylene terephthalate (PBT).

(Outer coating layer 3)
The outer coating layer 3 of Example 1 is made of a light-transmitting single resin that does not contain a color pigment, and is extruded with a circular second axial cross-sectional shape having a diameter that is at least twice the diameter of the inner coating layer 2. Is done. It contains 80% solidified volume or more of the same light transmissive resin as that of the inner coating layer 2 as a main agent, and is fixed to the inner coating layer 2 by being extruded in a semi-solidified state after the inner coating layer 2 is extruded. The property is good. The outer covering layer 3 has its own circular outer shape, and an enlarged display image that is distorted and projected on the outer shape of the actual stranded wire 1 or the inner covering layer 2 even if the cross-sectional shape is distorted due to elastic deformation when the wire is bent. Is displayed as an outline (FIG. 1). Specifically, as shown in FIG. 6, the first transmitted light L <b> 1 along the outer shape of the stranded wire 1 is primarily refracted outward by the lens effect of the inner coating layer 2, and then further by the lens effect of the inner coating layer 2. Second-order refraction in different directions. Further, as shown in FIG. 6, the second transmitted light L2 along the outer shape of the inner covering layer 2 is primarily refracted outward by the lens effect of the outer covering layer 3, and this refractive index is the second of the first transmitted light L1. It is smaller than the refractive index after the next refraction, and the outer diameter ratio of the stranded wire 1 and the inner coating layer 2 is projected on the outer surface of the outer coating layer 3 as different from the actual one.

(Lens effect and extrusion effect)
The inner coating layer 2 of Example 1 is composed of a resin containing a colored fluorescent pigment, a phosphorescent pigment, or a light reflecting material on the resin surface or inside the resin, so that the inner coating layer 2 and the outer coating layer 3 are: Each has a different light refraction function. Further, by forming each resin by extrusion molding, it is possible to continuously form the coated wire, and the productivity can be improved and provided at a relatively low cost.

(Configuration as wire lock)
The covered wire of Example 1 has a cylindrical receiving lock K1 overlaid and connected at one end, and an insertion lock K2 for the receiving lock is covered and connected at the other end. Configured as a wire lock. A locking key K3 can be inserted and removed at the further end of the cylindrical receiving lock K1. Such wire locks are required to have crime prevention and handling at the time of operation / accommodation. However, since the coated wire of the present invention projects the stranded wire 1 on the outer surface, the stranded wire 1 is relatively used in appearance. It appears as if it appears, and the double coating appears on the exterior, making it an exterior with high cutting strength and high crime prevention. Moreover, since the stranded wire 1 thinner than the projected image is actually coated with an elastic resin material, the flexibility is high. For example, the wire shape can be greatly deformed and locked, or the number of windings can be increased to accommodate the wire compactly.

  The coated wire of Example 2 shown in FIG. 2 (b) and FIG. 4 was formed in close contact with the stranded wire 1 composed of a double twist of 7 strands and the outer shape of the double twist of the stranded wire 1. An inner coating layer 2 having a true axial cross-sectional shape (first axial cross-sectional shape), a printed layer 4 fixedly formed without gaps along the circular outer surface of the inner coating layer 2, and the printed layer 4 are formed. The outer coating layer 3 is formed in close contact with the outer circular shape of the inner coating layer 2 without a gap, and has an axial cross-sectional shape (second axial cross-sectional shape) that is a perfect circle. Light is transmitted through each layer, and the internal structure of the wire including the outer shape of the stranded wire 1 can be visually recognized from the outside, and the outer coating layer 3 is formed by the lens effects of the inner coating layer 2 and the outer coating layer 3. The projected image 1I of the stranded wire 1 enlarged from the actual diameter and the projected image 2I of the inner coating layer 2 enlarged from the actual diameter are transmitted through and projected on the outer surface of the outer cover.

(Inner coating layer 2)
The inner coating layer 2 of Example 2 does not contain a colored pigment as compared with Example 1, and is made of a reflective material-containing resin containing a chip-like light reflecting material 21 inside the resin instead. Thereby, irregular reflection of light occurs inside the inner coating layer 2, and an aesthetic appearance different from that of the outer coating layer 3 is exhibited.

(Print layer 4)
In Example 2, the printing layer 4 made of a colored pattern is partially fixed and formed over the entire resin surface of the inner coating layer 2 (FIGS. 2 and 4). The outer coating layer 3 is formed on the fixing surface of the printing layer 4 in close contact, and the outer shape of the stranded wire 1 passes through the fixing surface of the printing layer 4 or passes through the fixing surface. Is magnified and projected. The fixing of the printing layer 4 is performed by laser printing, transfer printing, or the like. Since the printing layer 4 is fixedly formed on the surface of the inner coating layer 2, it is possible to display the appearance of characters and patterns stably and with an enlarged projection effect by the outer coating layer 3. Since the characters and patterns of the printing layer 4 are protected by the outer covering layer 3, blurring due to external rubbing hardly occurs and the long-term display property is excellent.

(Configuration as wire rope)
The coated wire of Example 2 is a rod-shaped wire rope having coupling loops 6 at both ends as shown in FIG. 4 as a whole by fixing both ends in a loop shape with a pair of cylindrical fasteners 5. Composed. In the inner covering layer 2, a continuous pattern printed layer 4 composed of a plurality of star shapes is formed only on the wire length portion between the fasteners 5 near both ends. The projected image 4I of the printed layer 4 is enlarged and displayed in appearance, and is projected as if it is lifted up in a light reflecting state by the reflection effect of the reflecting material 21 dispersed in the resin of the inner coating layer 2. Because it uses a reflective material, it can also be used as a safety rope at night. Further, since the pattern of the printing layer 4 is fixed and formed by transfer printing, the display effect can be maintained for a long time without being shifted or wrinkled like a decorative sheet. Moreover, the covering wire of the structure similar to Example 2 can also be used as an accessory rope for decoration. By using the printing layer 4 in combination with a reflective material or a resin containing a fluorescent pigment, the printing layer 4 is three-dimensionally raised, and has an excellent appearance as a decorative material.

  2 (c) and FIG. 5, the covered wire of Example 3 is similar to Example 1 in that a gap is formed along the outer shape of the stranded wire 1 composed of a double twist of 7 strands and the double twist of the stranded wire 1. The inner cross-sectional shape (first axial cross-sectional shape) formed in close contact and having a true circular shape and the axial cross-sectional shape (closely formed along the circular outer shape of the inner cover layer 2 without gaps) And an outer covering layer 3 having a second axial cross-sectional shape of a perfect circle. However, in Example 3, a bead-containing resin containing beads 22 that are spherical light reflecting materials 21 is used as a constituent resin material of the inner coating layer 2. In addition, the inner coating layer 2 and the outer coating layer 3 of Example 3 are made of a light-transmitting single resin that contains different color pigments and has the same constituent main component.

(Configuration as wire strap)
The covered wire of Example 3 is fixed by fixing the both ends in a loop shape with a cylindrical fastener 5, and by inserting a hanging holder 7 with an opening / closing lid into the loop portion 6 at the other end, as a whole 5 is configured as a coiled wire strap as shown in FIG. Since the inner coating layer 2 and the outer coating layer 3 are multicolored, the reflection effect of the beads 22 dispersed in the resin of the inner coating layer 2 is projected three-dimensionally by changing the color, and it is excellent as a decorative material. It will be.

[Examples 4 to 6]
7 (a), (b) and (c), the coated wires of Examples 4 to 6 whose only axial sectional views are shown are such that the inner coating layer 2 is extruded in a predetermined first axial sectional shape along the wire length direction. The outer coating layer 3 is extruded in a predetermined second axial cross-sectional shape different from the first polygonal cross-section along the wire length direction, whereby the inner coating layer 2 and the outer coating layer 3 are formed. It has a different axial cross-sectional shape. Among these, in particular, those shown in FIGS. 7A and 7B have the first axial cross-sectional shape of the inner coating layer 2 having a plurality of valley-shaped portions where adjacent sides intersect in a valley shape when viewed from the cross-sectional center side. It is polygonal (a grooved circle (a) and a star (b), respectively), and the second axial cross-sectional shape of the outer covering layer 3 is circular.

Also, as shown in FIGS. 7 (a) and 7 (b), the radial thickness of the inner coating layer 2 is relatively large in the axial cross-sectional view by forming a cross-sectional shape having a valley portion entering toward the center of the cross-section. Large thick portions and thin portions having a relatively small radial thickness can be formed alternately. Such a difference in the radial thickness of the inner coating layer 2 increases the lens effect as shown in FIG. The fixability of each layer is improved, and the in-plane projection image of the valley side is refracted and the projection image can be distorted.

Further, as shown in FIGS. 7B and 7C, by applying a planar printing layer 4 to each planar side surface of the inner coating layer 2 formed as a polygonal cross section, the characters of the printing layer 4 can be obtained by the photorefractive effect. Or it is projected in a state where the pattern is raised.

Example 7
The trial manufacture photograph of the covered wire of Example 7 which consists of a wire lock in FIGS. 8-10 is shown. The configuration of Example 7 is the same as that of Example 1. The constituent resin itself of the inner coating layer 2 includes an orange fluorescent pigment, and the constituent resin of the outer coating layer 3 is colorless and transparent. Since the coated wire is excellent in flexibility, it can be locked by double winding as shown in FIGS. Further, as shown in FIG. 10, the projected image 1I of the inner stranded wire 1 and the projected image 2I of the inner coating layer 2 are transmitted through the surface of the coated wire, that is, the surface of the outer coating layer 3, and emerge as a transparent fluorescent color. . These projected images 1I and 2I are thicker than the thickness of the actual internal structure (stranded wire 1 and internal coating layer 2).

In addition, the present invention is not limited to the above-described embodiments, and as long as it does not depart from the spirit of the present invention, the extraction of elements, the change of the combination of shapes of each layer, the omission, the change of the combination of constituent resin materials, It is possible to omit a part of the configuration or change the continuous number.
