[0064] The following description, with reference to the accompanying drawings, illustrates embodiments of the plated decorative components. These components are used, for example, as architectural hardware installed within buildings, such as small towel racks, large towel racks, toilet paper holders, door handles, or others.

[0065] [First Implementation]

[0066] Reference Figures 1-5 The plating decorative component 11 of the first embodiment will be described. Figure 1 This is a top view of the plated decorative component 11. Figure 2 This is the front view of the plated decorative component 11. Figure 3 This is a bottom view of the plated decorative component 11. Figure 4 This is a left view of the plated decorative component 11. Figure 5 This is a rear view of the plated decorative component 11. The right view of the plated decorative component 11 is shown below. Figure 4 The left view shown is symmetrical, therefore it is omitted from the illustration.

[0067] The plated decorative component 11 is used, for example, as architectural hardware, and more specifically, as a small towel rack.

[0068] The plated decorative component 11 includes a structural member 12 and a peripheral member 13 disposed near the structural member 12. In this embodiment, the structural member 12 and the peripheral member 13 are as follows: Figure 1 As shown, it is formed into a single, elongated ring shape in the horizontal direction.

[0069] The structural member 12 is a rod-shaped structure with a roughly quadrilateral cross-section, which is capable of draping towels or other strip-shaped objects over itself. The structural member 12 has a first plating portion 14 whose surface has been plated. The first plating portion 14 can be any one of a nickel-plated portion, a tin-cobalt-plated portion, or a chromium-plated portion.

[0070] Peripheral member 13 is disposed adjacent to structural member 12. Peripheral member 13 is approximately U-shaped, forming the portion of a transversely elongated, integral annular shape excluding structural member 12. Peripheral member 13 constitutes a support portion supporting structural member 12. Peripheral member 13 has mounting portions 15 for installation on a building wall. Figure 4 As shown, the peripheral component 13 is formed at an angle such that its installation height decreases as it moves away from the mounting part 15 installed on the building wall.

[0071] The peripheral component 13 has a second plating portion 16 and a light-transmitting three-dimensional pattern 17 formed on the surface of the second plating portion 16 and on the upper surface of the peripheral component 13. The second plating portion 16 can be any one of a nickel plating portion, a tin-cobalt alloy plating portion, or a chromium plating portion.

[0072] The three-dimensional pattern 17 is made of UV-curable resin. In this embodiment, the three-dimensional pattern 17 is formed by covering numerous square sheets in a grid pattern, which can reflect the metallic luster produced by the second plating portion 16 in a predetermined direction. Therefore, the three-dimensional pattern 17 of this embodiment has a metallic luster and can achieve a unique and novel texture with a tile-like appearance.

[0073] The type of 3D pattern 17 can be appropriately edited on a computer (PC) connected to the inkjet printer described later. Therefore, the geometry of the 3D pattern is not limited to the aforementioned tile style, but can adopt any geometry.

[0074] The function of the plated decorative component 11 in this embodiment will be explained. In this embodiment, the peripheral component 13 is provided as a support for the structural member 12 at a position where it leaves the structural member 12 that is draped over the strip such as a towel. Therefore, the strip will not drape over this part, preventing the three-dimensional pattern 17 from peeling off due to contact and friction of the strip.

[0075] The manufacturing method of the plated decorative component 11 according to this embodiment will be described. The manufacturing method of the plated decorative component 11 according to this embodiment generally includes three steps: a plated portion forming step, a transparent coating layer forming step, and a printing step. Furthermore, as an optional step, a second transparent coating layer forming step is performed after the printing step.

[0076] In the plating process, the substrate 18 of the architectural hardware, which is made of materials such as steel, is plated to form the first plating portion 14 of the structural member 12 and the second plating portion 16 of the peripheral member 13. The plating material is selected from any one of nickel plating, tin-cobalt alloy plating, and chromium plating.

[0077] During the formation of the nickel plating section, a Cu layer with a mass concentration of 99.9% or higher is formed as the base plating section, and a Ni layer with a mass concentration of 99.9% or higher is formed on its upper side as the final plating section.

[0078] During the formation of the tin-cobalt alloy plating section, a Cu layer with a concentration of 99.9% by mass or higher is formed as the base plating section, and a Ni layer with a concentration of 99.9% by mass or higher is formed on top of it as the base plating section. During the fabrication of the tin-cobalt alloy plating section, an alloy layer of Sn with a concentration of 60-65% by mass and Co with a concentration of 35-40% by mass is formed on top of the base plating section as the final plating section.

[0079] During the formation of the chromium-plated portion, a Cu layer with a concentration of 99.9% by mass or higher is formed as the base plating portion, and a Ni layer with a concentration of 99.9% by mass or higher is formed on top of it as the base plating portion. During the fabrication of the chromium-plated portion, a Cr layer with a concentration of 99.9% by mass or higher is formed on top of the base plating portion as the final plating portion.

[0080] A transparent coating layer forming process is performed on the second plating portion 16, which corresponds to the peripheral member 13, among the first plating portion 14 and the second plating portion 16 formed in the plating forming process. In addition to the second plating portion 16, the transparent coating layer forming process can also be performed on the first plating portion 14, which corresponds to the structural member 12. Various resin materials with light transmittance can be used for the transparent coating. In the transparent coating layer forming process, for example, a transparent coating layer can be formed relative to the second plating portion 16 by spraying. For example, thermosetting acrylic resins or polyurethane resins with light transmittance are suitable materials for the transparent coating layer. For example, a thermosetting acrylic resin manufactured by Daitoyo Coatings Co., Ltd., under the trade name GA Hard, can be used as the thermosetting acrylic resin. Furthermore, when the plated portion formed in the plating formation process is composed of the aforementioned chromium plating material, sufficient peel resistance is ensured, so this transparent coating layer formation process is not required, and the subsequent printing process can be directly performed on the second plated portion 16.

[0081] The printing process includes a degreasing process, a primer layer formation process, and a UV-curable ink layer formation process. In the degreasing process, the printing surface, which consists of a transparent coating layer or a second plating part 16, is cleaned using a degreasing material such as Dashears (manufactured by Kansai Moritz Co., Ltd.). Next, the substrate 18 of the plating decorative part 11 is placed on a specially manufactured jig, and the printing surface is kept horizontal.

[0082] Next, a primer layer formation process is performed using an inkjet printer, such as the UFJ-6042 (manufactured by MIMAKI ENGINEERING). In this process, a translucent primer ink, such as PR-200 (manufactured by MIMAKI ENGINEERING), is printed onto the printing surface to form the primer layer. The primer layer can also be formed directly relative to the second plating section 16, rather than on top of the transparent coating layer.

[0083] Next, a UV-curable ink layer forming process is performed. In this process, a translucent hard UV transparent ink, such as LH-100 (manufactured by MIMAKI ENGINEERING), is inkjet printed onto the printing surface where the primer layer has been formed. The inkjet printer prints according to an image of a stereoscopic pattern stored in a connected computer. The type of stereoscopic pattern 17 can be appropriately selected from several patterns by the operator performing the manufacturing operation. The resolution is, for example, 600×900 dpi. The UV-curable ink layer can be formed directly relative to the second plating section 16 instead of on top of the primer layer, or it can be formed on top of the transparent coating layer.

[0084] Next, an inkjet printer is used to perform a UV irradiation process. In this process, UV light is applied to the printed surface containing the hard UV transparent ink, causing the ink to cure. The UV irradiation can be performed once or multiple times.

[0085] After the UV irradiation process, a second transparent coating forming process can be performed arbitrarily. This process uses the same material as the aforementioned transparent coating layer for coating. In the second transparent coating layer forming process, a second transparent coating layer is formed relative to the second plating portion 16 (the first transparent coating layer) and the UV-curable ink layer above it. Therefore, the second transparent coating layer is formed to cover and protect the UV-curable ink layer. The second transparent coating layer forming process can also be performed on the first plating portion 14 (the first transparent coating layer) corresponding to the structural member 12. In the second transparent coating layer forming process, for example, the second transparent coating layer can be formed by spraying. Based on the above processes, a plating decorative component with a translucent three-dimensional pattern formed on the plating surface is completed.

[0086] According to this embodiment, the following can be summarized. The manufacturing method of the plated decorative component 11 includes: a plated portion forming step, in which a plated portion is formed by plated onto a substrate 18; a UV-curable ink layer forming step, in which a UV-curable ink with light transmittance is printed onto the plated portion to form a UV-curable ink layer with a three-dimensional pattern of a predetermined shape; and a UV irradiation step, in which the UV-curable ink layer is irradiated with UV light to cure it.

[0087] According to this configuration, by applying a translucent pattern to the plated area, a unique texture can be obtained by varying the gloss of the plated area. This gives the plated decorative part 11 a novel and extremely high-quality feel. Consequently, the unit price of the plated decorative part 11 can be increased. Furthermore, the plated area can be formed with raised or recessed areas without etching or other processes, allowing for a unique texture to be achieved with a simple process. This reduces manufacturing costs.

[0088] The manufacturing method of the plated decorative component further includes a primer layer forming step, in which a primer is printed on the plated part after the plated part forming step and before the UV-curable ink layer forming step, and a primer layer with a predetermined pattern is formed on the plated part. In the UV-curable ink layer forming step, a UV-curable ink layer with the predetermined pattern is formed on the upper side of the primer layer with the predetermined pattern.

[0089] Based on this structure, the UV-curable ink layer and the plated area can be firmly bonded together using a primer layer. This improves the durability of the patterned plated area.

[0090] The manufacturing method of the plated decorative component also includes a transparent coating layer forming step, in which a transparent coating is applied to the plated part to form a transparent coating layer after the plated part forming step and before the UV-curable ink layer forming step, and in the UV-curable ink layer forming step, a UV-curable ink layer with the predetermined pattern is formed on the upper side of the transparent coating layer.

[0091] Based on this configuration, a transparent coating can be used to prevent the plating portion printed with UV-curable ink from peeling off. This enables high durability of the plating portion.

[0092] The manufacturing method of the plated decorative component also includes a transparent coating layer forming step, in which a transparent coating is applied to the plated part to form a transparent coating layer after the plated part forming step and before the UV-curable ink layer forming step, and in the primer layer forming step, a primer layer with the predetermined pattern is formed on the upper side of the transparent coating layer.

[0093] Based on this configuration, a transparent coating can be used to prevent the plating layer, which is printed with UV-curable ink and primer, from peeling off. This allows for further improvement in the durability of the plating layer.

[0094] The manufacturing method of the plated decorative component further includes a second transparent coating layer forming step, in which a transparent coating is applied to the upper side of the UV-curable ink layer after the UV irradiation step to form the second transparent coating layer. According to this configuration, the second transparent coating layer forming step can prevent the UV-curable ink from peeling off. Therefore, high durability of both the plated part and the UV-curable ink layer can be achieved.

[0095] The UV-curable ink layer formation process is performed by inkjet printing. Based on this configuration, a masking process is unnecessary before printing the UV-curable ink, simplifying the manufacturing process and reducing manufacturing costs.

[0096] The substrate 18 is architectural hardware. Based on this configuration, the plated portion of the translucent three-dimensional pattern 17 can be formed with high durability. Therefore, the plated portion of the translucent three-dimensional pattern 17 can be appropriately applied to architectural hardware that requires high durability compared to general merchandise.

[0097] The plated decorative component 11 includes: a structural member 12 having a first plated portion 14, and a strip, a tube, or a finger hanging relative to the first plated portion 14; and a peripheral member 13 disposed near the structural member 12, having a second plated portion 16 and a three-dimensional pattern 17 of a predetermined shape that is translucent and formed on the surface of the second plated portion 16.

[0098] According to this configuration, instead of the structural member 12 for hanging on strips, tubes, or fingers, a peripheral member 13 with a translucent three-dimensional pattern 17 can be arranged on its surrounding periphery. This reduces the risk of the three-dimensional pattern 17 detaching due to contact or friction from strips, tubes, or fingers, enabling a highly durable plated decorative part 11. Furthermore, according to the above structure, the translucent three-dimensional pattern 17 does not impair the gloss of the second plated portion 16, and a unique texture can be imparted through the three-dimensional shape of the pattern. This gives the plated decorative part 11 an extremely high-quality, premium feel. Consequently, the unit price of the plated decorative part 11 can be increased.

[0099] The three-dimensional pattern 17 is made of a translucent resin. With this structure, for example, a three-dimensional pattern 17 can be formed on the plated area using an extremely simple process without using methods such as etching to melt the plated area to create an uneven surface. Furthermore, the plated area is not chemically or mechanically damaged, thus achieving a highly durable plated area.

[0100] The resin is a UV-curable resin. With this configuration, it can be cured using UV light in a short time, reducing manufacturing time. Furthermore, by using UV curing, the three-dimensional pattern 17 can be firmly fixed to the plated portion. Thus, a plated decorative part 11 with a highly durable plated portion featuring the three-dimensional pattern 17 can be achieved.

[0101] The resin is printed using an inkjet printing method. According to this configuration, a masking process is unnecessary, and a three-dimensional pattern 17 can be formed relative to the plated portion through an extremely simple process. This simplifies the manufacturing process and reduces manufacturing costs.

[0102] The peripheral component 13 has a transparent coating layer covering the three-dimensional pattern 17 on the upper side. With this configuration, it is possible to further prevent the three-dimensional pattern 17 from peeling off, thereby achieving a highly durable plated decorative component 11.

[0103] The peripheral component 13 forms the support portion of the structural component 12. With this configuration, the plating portion with the three-dimensional pattern 17 can be positioned in a location easily visible to the user without being obstructed by strips, tubes, or fingers, and in a location with minimal contact and friction. Thus, a plating decorative component 11 can be achieved that offers a superior, high-end feel, high durability, and low cost—features not previously available.

[0104] At least one of the structural member 12 and the peripheral member 13 is architectural hardware. According to this configuration, the plating portion of the translucent three-dimensional pattern 17 can be formed with high durability. Therefore, the plating portion of the translucent three-dimensional pattern 17 can be appropriately applied to architectural hardware that requires high durability compared to general merchandise.

[0105] In the following embodiments, the parts that differ from the first embodiment will be described in detail. For the parts that are common to the first embodiment, illustrations or descriptions will be omitted.

[0106] [Second Implementation]

The bottom view of the plated decorative component 11 is shown below. Figure 3 The bottom view of the plated decorative component 11 shown in the first embodiment is the same, therefore the illustration is omitted. The left view of the plated decorative component 11 is the same as... Figure 4 The left view of the plated decorative component 11 shown in the first embodiment is the same, so it is omitted from the drawing. The right view of the plated decorative component 11 is the same as... Figure 4 The left view of the plated decorative component 11 of the first embodiment shown is symmetrical, therefore the illustration is omitted. The rear view of the plated decorative component 11 is symmetrical to... Figure 5 The rear view of the plated decorative component 11 shown in the first embodiment is the same, so the illustration is omitted.

[0109] In this embodiment, the shape of the substrate 18 constituting the plating decorative component 11 is the same as in the first embodiment, except that the three-dimensional pattern 17 formed on the second plating portion 16 of the peripheral member 13 is different from that in the first embodiment. The position and size of the three-dimensional pattern 17 are the same as in the first embodiment.

[0110] The three-dimensional pattern 17 is made of a UV-curable resin. In this embodiment, the three-dimensional pattern 17 is arranged in a form where the waveforms are staggered in the front-to-back direction, which can reflect the metallic luster produced by the second plating portion in a predetermined direction. Therefore, the three-dimensional pattern 17 of this embodiment has a metallic luster and can exhibit a novel and unique texture with bright and dark areas of the waveforms.

[0111] The type of 3D pattern 17 can be appropriately edited on a computer (PC) connected to the inkjet printer described later. Therefore, the geometry of the 3D pattern 17 is not limited to the aforementioned waveform, but can adopt any geometry.

[0112] The function and manufacturing method of the plated decorative component 11 in this embodiment are the same as those in the first embodiment. Regarding the three-dimensional pattern 17, by replacing the three-dimensional pattern 17 of the first embodiment with the three-dimensional pattern 17 of the second embodiment on a computer (PC) connected to the inkjet printer, it can be easily changed to the three-dimensional pattern 17 of this embodiment. Furthermore, the three-dimensional pattern 17 is not limited to the patterns of the first and second embodiments; other three-dimensional patterns can also be appropriately applied.

[0113] [Third Implementation]

[0114] Reference Figures 8-12 The plating decorative component 11 of the third embodiment will now be described. The plating decorative component 11 of the third embodiment is used, for example, as architectural hardware, and more specifically, as a large towel rack.

[0115] Figure 8 This is a top view of the plated decorative component 11. Figure 9 This is the front view of the plated decorative component 11. Figure 10 This is a bottom view of the plated decorative component 11. Figure 11 This is a left view of the plated decorative component 11. Figure 12 This is a rear view of the plated decorative component 11. The right view of the plated decorative component 11 is shown below. Figure 11 The left view shown is symmetrical, therefore it is omitted from the illustration.

[0116] The structural member 12 is a rod-shaped structure with a roughly quadrilateral cross-section, capable of draping towels or other strip-shaped objects over it. The length of the structural member 12 in the longitudinal direction is longer than that of the structural member 12 in the first embodiment. The structural member 12 has a first plating portion 14 whose surface has been plated. The first plating portion 14 can be any one of a nickel plating portion, a tin-cobalt plating portion, or a chromium plating portion.

[0117] Peripheral member 13 is disposed adjacent to structural member 12. Peripheral member 13 is block-shaped and protrudes away from the wall surface on which the plating decorative component 11 is mounted. Peripheral member 13 constitutes a support portion for supporting structural member 12. Peripheral member 13 has mounting portion 15 for mounting to building wall.

[0118] The peripheral component 13 has a second plating portion 16 and a light-transmitting three-dimensional pattern 17 formed on the surface of the second plating portion 16 and on the upper surface of the peripheral component 13. The second plating portion 16 can be any one of a nickel plating portion, a tin-cobalt alloy plating portion, or a chromium plating portion.

[0119] In this embodiment, the shape of the substrate 18 constituting the plating decorative component 11 is different from that in the first embodiment, but the three-dimensional pattern 17 formed on the second plating portion 16 of the peripheral member 13 is the same as that in the first embodiment. Therefore, the three-dimensional pattern 17 of this embodiment has a metallic luster and can achieve a unique new texture with a tile-style appearance.

[0120] The function of the plated decorative component 11 in this embodiment will be explained. In this embodiment, the peripheral component 13 is provided as a support for the structural member 12 at a position where it leaves the structural member 12 that is draped over the strip such as a towel. Therefore, the strip will not drape over this part, preventing the three-dimensional pattern 17 from peeling off due to contact and friction of the strip.

[0121] The function and manufacturing method of the plated decorative component 11 in this embodiment are the same as those in the first embodiment. Regarding the three-dimensional pattern 17, the three-dimensional pattern 17 of the first embodiment can be directly used on a computer (PC) connected to the inkjet printer. Furthermore, the three-dimensional pattern 17 is not limited to the pattern of the first embodiment, and other three-dimensional patterns 17 can also be appropriately applied.

Figure 16 This is a bottom view of the plated decorative component 11. Figure 17 This is a left view of the plated decorative component 11. Figure 18 This is a right view of the plated decorative component 11. Figure 19 This is a rear view of the plated decorative component 11.

[0132] The plated decorative component 11 includes a structural member 12 and peripheral members 13 located near the structural member 12. Both the structural member 12 and the peripheral members 13 are architectural hardware.

[0133] Frame component 12 is a rod-shaped structure with a roughly quadrilateral cross-section, such as... Figure 16 As shown, it is bent into a shape roughly the letter "C". Figure 20As shown, it is possible to attach cylindrical objects such as toilet paper to the frame member 12. The frame member 12 has a first plated portion 14 whose surface has been plated. The first plated portion 14 can be any one of a nickel-plated portion, a tin-cobalt-plated portion, or a chromium-plated portion.

[0134] Peripheral component 13 is disposed adjacent to the upper side of structural component 12. Peripheral component 13 is composed of a cover that covers and hangs on the structural component 12 a cylindrical body such as toilet paper.

[0135] The peripheral component 13 has a peripheral component body 21, a mounting portion 15 for mounting on a building wall, a support portion 22 for supporting the frame member 12, and a hinge portion 23 provided on the support portion 22 and supporting the peripheral component body 21 in a manner that allows the peripheral component body 21 to rotate. The peripheral component body 21 is formed in the shape of a flat plate.

[0136] The peripheral component 13 has a second plating portion 16 and a translucent three-dimensional pattern 17 formed on the surface of the second plating portion 16 and on the upper surface of the peripheral component body 21.

[0139] The function of the plated decorative component 11 in this embodiment will be explained. In this embodiment, as... Figure 20 As shown, the peripheral member 13 is provided as a cover for the cylindrical body 31 at a position where it is detached from the structural member 12 on which the cylindrical body 31, such as toilet paper, is attached. At this time, the main body 21 of the peripheral member can rotate around the hinge portion 23, allowing the cylindrical body 31 to be attached relative to the inner structural member 12. Therefore, the cylindrical body 31 will not be attached to the peripheral member 13, preventing the peeling of the three-dimensional pattern 17 due to contact and friction of the cylindrical body 31.

[0140] The function and manufacturing method of the plated decorative component 11 in this embodiment are the same as those in the first embodiment. Furthermore, the three-dimensional pattern 17 is not limited to the pattern of the first embodiment; other three-dimensional patterns 17 can also be appropriately applied.

[0141] Based on this embodiment, the following can be summarized: The peripheral component 13 is a cover that covers the cylindrical body 31 that is suspended on the structural component 12.

[0142] According to this configuration, the plating part with the three-dimensional pattern 17 can be arranged in a position that is not obstructed by the cylindrical body, is easily visible to the user, and has minimal contact and friction. As a result, a plating decorative part 11 can be achieved that provides a high-quality, premium feel, high durability, and low cost, unlike anything previously available.
