[0055] [First embodiment]

[0056] <Decorative parts>

[0057] Figure 1 and Figure 2 The decorative component 10 shown in the figure comprises: a plate 2 having a hollowed-out pattern portion 20 (see Figure 3); a resin film 1 disposed on a first surface 2a of a plate 2; and a resin layer 3 disposed on a second surface 2b of the plate 2. The first surface 2a and the second surface 2b are located on opposite sides in the thickness direction of the plate 2. The hollow pattern portion 20 has a through hole 22 that penetrates the plate 2 in the thickness direction.

[0058] In addition, the hollowed-out pattern portion 20 has a separator 23, which is disposed in the through hole 22 at a distance from the inner periphery of the through hole 22. That is, the plate body 21 of the plate 2 and the separator 23 exist separately across the space formed by the through hole 22. The number of through holes 22 and separators 23 in the plate 2 is not particularly limited. The plate 2 may also have a through hole 22 without a separator 23 disposed therein.

[0059] The resin film 1, the plate 2 and the resin layer 3 of the decorative component 10 are directly stacked in order from the visual observer side. The decorative component 10 can be used, for example, for interior panels of automobiles (door trim, decorative cover for center console, decorative cover for instrument panel, etc.). The decorative component 10 can also be used as an alarm display for seat belts, door locks, etc., a display device for air conditioners, audio, etc.

[0060] Since the resin film 1 is disposed on the first surface 2a of the plate 2, the decorative component 10 can support the inner peripheral edge of the through hole 22 by the resin film 1. Therefore, the decorative component 10 can easily dispose the resin layer 3 on the second surface 2b of the plate 2 while the plate 2 is supported by the resin film 1 in a desired shape. Therefore, the decorative component 10 can easily obtain a desired hollowing pattern.

[0061] In addition, since the resin film 1 is disposed on the first surface 2a of the plate 2, the decorative component 10 can support the separator 23 by the resin film 1. Therefore, the decorative component 10 can easily arrange the resin layer 3 on the second surface 2b of the plate 2 in a state where the separator 23 is supported by the resin film 1. That is, the decorative component 10 positions the plate body 21 and the separator 23 on the resin film 1, and preferably, easily arranges the resin layer 3 on the second surface 2b of the plate 2 in a state where the plate body 21 and the separator 23 are bonded to the resin film 1. Therefore, the decorative component 10 can more easily obtain a desired hollowing pattern.

[0062] (resin film)

[0063] The resin film 1 may constitute the outermost layer (the layer exposed to the viewer) of the decorative member 10. The resin film 1 has an adhesive surface facing the first surface 2a of the plate 2. The plate body 21 and the separator 23 are fixed to the adhesive surface.

[0064] As mentioned above, the decorative component 10 is provided with a resin film 1, so that the plate body 21 and the separator 23 can be easily positioned. In addition, the decorative component 10 is provided with a resin film 1, so that the thickness of the resin layer arranged on the side closer to the visual observer than the plate 2 is uniformed and the manufacturing efficiency is easily improved. That is, if a coating layer is arranged instead of the resin film 1, the positioning of the plate 2 becomes difficult, and uneven coating is likely to occur, and the thickness is likely to become uneven. In addition, since waste such as solvents is generated during the coating process, the environmental load becomes large. In contrast, according to the decorative component 10, it is easy to suppress the environmental load and form a fine resin layer.

[0065] The resin film 1 is flexible. The resin film 1 may be transparent. As the main component of the resin film 1, for example, vinyl resins such as polyvinyl chloride and polyvinyl acetate, acrylic resins, polyolefins, polystyrene, acrylonitrile-butadiene-styrene copolymers (ABS resins), polyesters, polycarbonates, cellulose resins, polyamides, thermoplastic polyurethanes, fluororesins and other thermoplastic resins, epoxy resins, thermosetting polyurethanes and other thermosetting resins can be cited. It should be noted that the "main component" refers to the component with the largest content, for example, a component with a content of 50% by mass or more.

[0066] The thickness of the resin film 1 is not particularly limited, but is preferably thinner from the viewpoint of easily expressing the texture of the plate 2. As the lower limit of the average thickness of the resin film 1, from the viewpoint of properly supporting the plate 2, it is preferably 10 μm, and more preferably 30 μm. On the other hand, as the upper limit of the average thickness of the resin film 1, from the viewpoint of being able to fully express the texture of the plate 2, it is preferably 150 μm, more preferably 100 μm, and further preferably 80 μm. In addition, as the thickness of the resin film 1, from the viewpoint of reproducing the texture like a mirror coating, it is preferably thick. In this case, as the lower limit of the average thickness of the resin film 1, it is preferably 500 μm, and more preferably 1000 μm.

[0067] The resin film 1 may have an adhesive layer on the surface layer of the side bonded to the plate 2. In addition, the resin film 1 may contain any other components within the range of achieving the effect of the present disclosure. In addition, from the viewpoint of obtaining the desired decorative effect, the decorative component 10 may be laminated with a coating layer on the resin film 1. Even when the decorative component 10 is laminated with a coating layer on the resin film 1, it is easy to suppress the environmental load, etc. compared with the existing decorative components.

[0068] (Plate)

[0069] The plate 2 is configured to be able to express a hollow pattern such as a character or a graphic using the plate body 21, the through hole 22, and the separator 23. The plate body 21 and the separator 23 define the outline of the hollow pattern. Figure 3As shown, the plate 2 has, for example, a plurality of through holes 22 (among the plurality of through holes 22, there may be through holes 22 without separation sheets 23), and a hollow pattern portion 20 is formed by the through holes 22, the plate body 21 arranged inside and outside the through holes 22, and the design represented by the separation sheets 23.

[0070] When there is a through hole 22 without a separator 23 in the plate 2, the lower limit of the minimum width of the through hole 22 is preferably 0.2 mm, more preferably 0.25 mm, from the viewpoint that a visual observer can easily discern the hollowing pattern. On the other hand, the upper limit of the minimum width of the through hole 22 may be, for example, 0.4 mm or 0.35 mm.

[0071] The lower limit of the surface area of ​​the separator 23 may be 0.03 mm from the viewpoint that a visual observer can easily identify the hollow pattern. 2 , or 0.06mm 2 .

[0072] The through hole 22 is preferably formed so that the central axis extends in the thickness direction of the plate 2. The through hole 22 may be formed in a tapered shape. For example, the through hole 22 may be arranged to expand in diameter from the first surface 2a toward the second surface 2b of the plate 2. By configuring in this manner, it is suppressed that the inner peripheral surface of the through hole 22 is visually observed by a visual observer, and it is easy to increase the viewing angle of the hollowed-out pattern portion 20.

[0073] The lower limit of the average thickness of the plate 2 is preferably 0.1 mm, more preferably 0.2 mm, from the viewpoint of suppressing the reduction of processability and visual observability of wood grain. On the other hand, the upper limit of the average thickness can be 0.5 mm or 0.4 mm from the viewpoint of easily and reliably filling the through hole 22 with the resin layer 3.

[0074] The board 2 may be a laminate of a plurality of veneers, but is preferably composed of a single veneer. As the material of the board 2, for example, a peeled veneer obtained by circumferentially cutting a log in a manner of peeling the bark, a sawn board obtained by cutting a log with a saw, or a planed board obtained by slicing a log with a sharp knife can be used. Since the peeled veneer can be a veneer whose width exceeds the thickness of the log, a large veneer can be obtained relatively cheaply. Therefore, by using a peeled veneer as the board 2, the size of the decorative component 10 can be increased relatively easily and cheaply. In addition, by using a peeled veneer as the board 2, the deformation of the decorative component 10 caused by humidity changes and time changes can be suppressed. When a peeled veneer is used as the board 2, the decorative component 10 is close to a natural wood grain board, and the quality is relatively stable.

[0075] The type of wood of the plate 2 is not particularly limited, and any type of wood that can provide a desired design may be selected. Examples of the type of wood include walnut, maple, and ash.

[0076] like Figure 2 As shown, the resin film 1 is directly laminated on the first surface 2a of the plate 2. By configuring in this way, the plate body 21 and the separator 23 are directly fixed to the resin film 1 on the first surface 2a.

[0077] like Figure 4 As shown, the first surface 2a of the plate 2 may be impregnated with the decorative resin 4. That is, the plate 2 may have a resin impregnated portion 2c, the surface layer of which is impregnated with the decorative resin 4 on the first surface 2a side. According to this structure, the resin film 1 is arranged to contact the resin impregnated portion 2c.

[0078] The resin film 1 and the resin impregnation portion 2c are preferably bonded to each other by resin, and more preferably chemically bonded to each other by resin. That is, the decorative component 10 includes the decorative resin 4 impregnated on the first surface 2a of the plate 2, and the resin film 1 and the decorative resin 4 are preferably bonded to each other, and more preferably the resin contained in the resin film 1 and the decorative resin 4 are chemically bonded. By configuring in this way, the plate body 21 and the separator 23 can be easily and reliably fixed to the resin film 1 on the first surface 2a.

[0079] The main component of the decorative resin 4 can be selected according to the application, but it is preferably selected from the viewpoint of adhesion to the resin contained in the resin film 1. As the main component of the decorative resin 4, for example, vinyl resins such as polyvinyl chloride and polyvinyl acetate, acrylic resins, polyolefins, polystyrene, ABS resins, polyesters, polycarbonates, cellulose resins, polyamides, thermoplastic polyurethanes, fluororesins and other thermoplastic resins, and thermosetting resins such as epoxy resins and thermosetting polyurethanes can be cited. The main component of the decorative resin 4 may be the same as or different from the resin contained in the resin film 1. By making the main component of the decorative resin 4 the same as the resin contained in the resin film 1, the adhesion between the resin film 1 and the plate 2 can be easily improved. On the other hand, by making the main component of the decorative resin 4 different from the resin contained in the resin film 1, the decorative effect based on the decorative resin 4 can be easily improved.

[0080] (resin layer)

[0081] For example, the resin layer 3 is formed by solidifying the injection resin supplied to the second surface 2b of the plate 2. In this case, the resin layer 3 is formed as an injection resin layer. The resin layer 3 is stacked on the second surface 2b of the plate 2 and fills the through hole 22. In addition, when a separator 23 is arranged in the through hole 22, the resin layer 3 is filled in the gap between the inner periphery of the through hole 22 and the separator 23. That is, as Figure 2 As shown, the resin layer 3 has a first portion 3a stacked on the second surface 2b of the plate 2 (and an extension of the second surface 2b) and a second portion 3b filled in the through hole 22. The first portion 3a and the second portion 3b are integrally formed by the same injection molding resin. The first portion 3a is directly bonded to the second surface 2b of the plate 2. The second portion 3b is directly bonded to the resin film 1 at the front end portion on the opposite side to the first portion 3a. It should be noted that the steps for forming the resin layer 3 are not particularly limited. For example, the resin layer 3 can be a resin layer formed by curing the resin coated on the second surface 2b of the plate 2.

[0082] The decorative component 10 preferably has the resin film 1 and the resin layer 3 bonded to the end portion on the first surface 2a side of the through hole 22. In this case, the resin film 1 and the resin layer 3 can be bonded to each other on the extended surface of the first surface 2a. Since the decorative component 10 easily suppresses the deflection of the resin film 1 in the through hole 22, the resin film 1 and the resin layer 3 can be easily bonded to each other on the extended surface of the first surface 2a. In addition, the resin film 1 and the resin layer 3 are also preferably chemically bonded to each other by resin. By being constructed in this way, the decorative component 10 can fix the inner peripheral edge portion of the through hole 22 and the separator 23 at the desired position and improve the manufacturing efficiency.

[0083] Examples of the injection resin include thermoplastic resins such as acrylic resin, polycarbonate, ABS resin, acrylonitrile-ethylene-propylene-diene-styrene copolymer (AES resin), acrylonitrile-styrene-acrylate copolymer (ASA resin), and acrylonitrile-styrene copolymer (AS resin).

[0084] The lower limit of the average thickness of the resin layer 3 (the average thickness of the first portion 3a) may be 1.0 mm or 1.5 mm from the viewpoint of satisfying the required strength, etc. On the other hand, the upper limit of the average thickness may be 6.0 mm or 5.0 mm from the viewpoint of promoting the thinning of the decorative component 10, etc.

[0085] <Laminates for decorative parts>

[0086] As described above, the decorative component 10 includes a plate 2 having a hollow pattern portion 20 and a resin film 1 bonded to a first surface 2a of the plate. A decorative component laminate 30 (see Figure 2 ) is one embodiment of the present disclosure. That is, the decorative component laminate 30 includes a plate 2 having a hollow pattern portion 20 and a resin film 1 bonded to a first surface 2a of the plate. The hollow pattern portion 20 has a through hole 22 that penetrates the plate 2 in the thickness direction. In addition, the hollow pattern portion 20 has a separator 23 that is disposed in the through hole 22 to be separated from the inner periphery of the through hole 22.

[0087] Since the resin film 1 is bonded to the first surface 2a of the plate 2, the decorative component laminate 30 can support the inner peripheral edge of the through hole 22 and the separator 23 by the resin film 1. Therefore, the decorative component laminate 30 can easily obtain a desired hollow pattern.

[0088] <Method for manufacturing decorative parts>

[0089] Reference Figure 5 , an example of a method for manufacturing the decorative component (hereinafter referred to as "the manufacturing method") is described. The manufacturing method adheres a resin film to a first surface (S1) of a plate having a hollowed-out pattern portion, arranges the plate to which the resin film is adhered in a cavity of a mold (S2), and supplies injection resin to a second surface of the plate arranged in the cavity (S3). In the manufacturing method, the hollowed-out pattern portion has a through hole that penetrates the plate in the thickness direction. In addition, in the manufacturing method, the hollowed-out pattern portion has a separator, and the separator is arranged in the through hole separately from the inner periphery of the through hole.

[0090] Since the manufacturing method arranges the laminate of the resin film and the plate in the cavity of the mold in a state where the plate is bonded to the resin film, it is difficult for the plate to deviate relative to the resin film during the supply and curing of the injection resin. Therefore, according to the manufacturing method, a desired hollowing pattern can be easily formed.

[0091] The following is a description of each step of the manufacturing method. Figure 1 and Figure 2 It should be noted that in the following description, the specific structures of the resin film 1, the plate 2 and the resin layer 3 can be set to the same as Figure 1 and Figure 2 The decorative part 10 is the same.

[0092] (S1)

[0093] In S1 (hereinafter also referred to as "bonding step S1"), as Figure 6 and Figure 7 As shown, the sheet body 21 and the separator 23 are fixed to the surface of the resin film 1. In the bonding step S1, the sheet body 21 and the separator 23 are aligned with respect to the resin film 1 in such a way that a desired hollowing pattern can be obtained, and then the sheet body 21 and the separator 23 are bonded to the resin film 1.

[0094] In the bonding step S1, for example, the resin film 1 and the plate 2 may be bonded by hot pressing the resin film 1 on the first surface 2a of the plate 2, or an adhesive layer may be formed in advance on the surface layer of the resin film 1 on the side to be bonded to the plate 2, and the resin film 1 and the plate 2 may be bonded through the adhesive layer. In addition, in the bonding step S1, the decorative resin may be impregnated in advance on the first surface 2a of the plate 2, and the resin contained in the resin film 1 may be bonded to the decorative resin. In this case, it is preferred that the resin contained in the resin film 1 is chemically bonded to the decorative resin. It should be noted that when the plate 2 is bonded to the resin film 1, the second surface 2b of the plate 2 may be supported by other components.

[0095] The laminate of the resin film 1 and the plate 2 formed by the bonding step S1 is configured as the laminate 30 for the decorative component.

[0096] (S2)

[0097] In S2 (hereinafter also referred to as "configuration step S2"), if Figure 8 As shown, the decorative component laminate 30 is arranged in the cavity C of the mold 40. In the arrangement step S2, the decorative component laminate 30 is arranged in the cavity C so that the surface of the resin film 1 contacts the inner surface of the mold 40. In the arrangement step S2, the decorative component laminate 30 is preferably arranged in the cavity C so that the surface of the resin film 1 is supported by the inner surface of the mold 40 as a whole.

[0098] In this manufacturing method, since the plate 2 is bonded to the resin film 1 in the bonding step S1, the positional deviation of the separator 23 relative to the resin film 1 can be suppressed in the arrangement step S2. Therefore, by positioning the resin film 1 in the cavity C, the separator 23 can be positioned in the cavity C at the same time.

[0099] (S3)

[0100] In S3 (hereinafter also referred to as "supply step S3"), in a state where the decorative component laminate 30 is arranged in the cavity C, the injection resin is supplied to the second surface 2b of the plate 2. In this way, the injection resin is laminated on the second surface 2b of the plate 2 and filled into the through hole 22. In addition, when the separator 23 is arranged in the through hole 22, the injection resin is filled into the gap between the inner peripheral edge of the through hole 22 and the separator 23.

[0101] In the supplying step S3, after the injection resin is supplied, the injection resin is solidified to form a resin layer 3 on the second surface 2b of the plate 2. As a result, a Figure 1 and Figure 2 The decorative part 10.

[0102] [Second embodiment]

[0103] <Light-emitting module>

[0104] Fig. 9 The light-emitting module 100 includes the decorative component 10 and a light-emitting unit 50 disposed on the back side of the resin layer 3 in the decorative component 10. The light-emitting unit 50 includes one or more light sources 51 and a support 52 that supports the one or more light sources 51. The light source 51 is not particularly limited, and examples thereof include LEDs, fluorescent lamps, and the like. The light-emitting unit 50 may be configured such that, in a structure having a plurality of light sources 51, these light sources 51 can be partially lit and extinguished.

[0105] Since the light emitting module 100 includes the light emitting portion 50 on the back side of the decorative member 10 , the visibility of the hollow pattern formed on the plate material 2 can be improved.

[0106] [Other embodiments]

[0107] The above embodiments are not intended to limit the structure of the present invention. Therefore, for the above embodiments, the constituent elements of each part of the above embodiments can be omitted, replaced or added based on the description of this specification and technical common sense, which should be interpreted as belonging to the scope of the present invention.

[0108] The decorative component can form a desired hollowed-out pattern portion with a simple structure by directly stacking a resin film, a plate, and a resin layer in sequence. However, the present disclosure does not exclude a structure in which other layers are stacked between the resin film and the plate, or a structure in which other layers are stacked between the plate and the resin layer. That is, the decorative component can also adopt a structure in which the resin film is indirectly arranged on the first surface of the plate, or a structure in which the resin layer is indirectly arranged on the second surface of the plate.

[0109] The decorative component can be configured such that the resin film is disposed on the first surface of the plate so that the resin film and the resin layer can be easily bonded at the end of the first surface side of the through hole. However, in the through hole, the resin film and the resin layer can also be bonded at a portion other than the end of the first surface side. In addition, the decorative component can also be configured such that a component other than the injection resin is filled in the through hole.

[0110] In the above embodiment, the hollowed-out pattern portion has a separator, and the separator is arranged in the through hole separately from the inner periphery of the through hole. However, the decorative component can also adopt a structure without the separator. In the structure of the decorative component, for example, an edge protruding into the through hole is formed on the inner periphery of the through hole, and the edge can be supported by the resin film in a desired shape. As a result, the decorative component can easily obtain a desired hollowed-out pattern.

[0111] In the decorative component laminate, a layer other than the resin may be laminated on the second surface of the plate.
