Description

[Technical field]

[0001] The present invention relates to an interior part and an assembly structure thereof, and more particularly to an interior part provided with an optical fiber skin material and an assembly structure thereof. [Background technology]

[0002] Conventionally, interior parts that include a base material and an optical fiber skin material that covers the surface of the base material are generally known (see, for example, Patent Document 1, etc.). As an assembly structure for this type of interior part, a mounting structure in which a mating part (peripheral part) is placed from the design surface side of the interior part (see FIG. 5 of Patent Document 1), or a back-cutting structure in which the interior part is assembled from the back side of the mating part (see FIG. 7 of Patent Document 1) is recommended.

[0003] On the other hand, a mounting structure in which a mating part is placed on the back side of an interior part, or a back-cutting structure in which an interior part is assembled from the front side of a mating part, are also generally known. In these structures, for example, as shown in FIG. 16(a), an optical fiber skin material 103 is used in which a cushion layer 107 is laminated on the back side of a fabric 106 in which optical fibers are woven, and an interior part 101 is often used in which a terminal part 103a of the optical fiber skin material 103 is wrapped around one end side of a base material 102 (specifically, a vertical wall part 102b). In this case, by using a thick cushion layer 107 (e.g., 5 mm thick, etc.), a sufficient size (e.g., a radius of 6 mm, etc.) can be secured as the design R113 of the optical fiber skin material 103 (i.e., the design R113 of the part mating part with the mating part 133). As a result, light leakage from the part mating part between the optical fiber skin material 103 and the mating part 133 is suppressed, and the occurrence of partially bright spots is suppressed.

[0004] [Patent Document 1] JP 2018-197083 A Summary of the Invention [Problem to be solved by the invention]

[0005] Here, in order to realize a hard texture, it may be required to adopt an optical fiber skin material with a thin cushion layer or without a cushion layer. However, when such an optical fiber skin material is adopted, it is difficult to secure a sufficient size as the design R113 of the optical fiber skin material 103', for example, as shown in Fig. 16(b). As a result, light leakage may occur from the part mating portion between the optical fiber skin material 103' and the mating part 133, resulting in the occurrence of partially bright spots.

[0006] The above problem is particularly noticeable at the mating portion between the optical fiber skin 103' that is wound around the tip end side of the standing wall portion 102b of the base material 102 and the mating part 133. However, the same problem may occur at the mating portion between the optical fiber skin 103' that is wound around the tip end side of the base material 102 that does not have the standing wall portion 102b and the mating part 133.

[0007] The present invention has been made in consideration of the above-mentioned current situation, and has an object to provide an interior part and an assembly structure thereof that can suppress light leakage from a part mating portion between an optical fiber skin material and a mating part, even when an optical fiber skin material having a thin cushion layer or no cushion layer is used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The matters shown herein are illustrative and are intended to exemplify the embodiments of the present invention, and are described for the purpose of providing what is believed to be the most effective and easily understandable explanation of the principles and conceptual features of the present invention. In this respect, it is not intended to show structural details of the present invention beyond the extent necessary for a fundamental understanding of the present invention, and the description in conjunction with the drawings will make it clear to those skilled in the art how some forms of the present invention can be actually embodied.

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to the drawings. In the present embodiment, an ornament 1A constituting a vehicle door trim 30 is exemplified as an "interior part" according to the present invention.

[0013] 1 and 2, a vehicle door trim 30 includes a trim body 31 that covers a metal panel 32 from the inside of the vehicle compartment. The metal panel 32 is provided with a mating part 33 that is abutted against an ornament 1A. The trim body 31 includes the ornament 1A, an upper board 34, and a lower board 35 that form a design surface on the inside of the vehicle compartment. The ornament 1A is disposed between the upper board 34 and the lower board 35.

[0014] <Embodiment 1> 2 and 3, the ornament 1A according to this embodiment includes a base material 2 and an optical fiber skin material 3 (hereinafter, also simply referred to as "skin material 3") that covers the entire surface (or a part) of the base material 2. The skin material 3 is usually attached to the surface of the base material 2 with an adhesive or the like.

[0015] The base material 2 is made of synthetic resin and formed into a plate shape (see FIG. 5). The base material 2 has a surface portion 2a and a standing wall portion 2b rising from one edge of the surface portion 2a. The surface portion 2a is formed into a substantially rectangular shape in plan view. The base material 2 has a predetermined plate thickness (e.g., 2 mm). The back surface of the base material 2 (specifically, the back surface of the surface portion 2a) is provided with a plurality of fastening bosses 4 for fastening the base material 2 to a base member (not shown).

[0016] The substrate 2 may contain a thermoplastic resin. Examples of the thermoplastic resin include polyolefin (particularly polypropylene), polyester, polystyrene, acrylic, polyamide, polycarbonate, polyacetal, and ABS. These may be used alone or in combination of two or more. Furthermore, the substrate 2 may contain the above-mentioned thermoplastic resin and reinforcing fibers. Examples of the reinforcing fibers include inorganic fibers (glass fibers, carbon fibers, etc.) and organic fibers (natural fibers such as plant fibers and animal fibers, or resin fibers such as polyester, polyamide, and aramid). These may be used alone or in combination of two or more. In addition, the plant fibers include bast-based plant fibers (e.g., kenaf, flax, jute, hemp, ramie, etc.), leaf vein-based plant fibers (e.g., abaca, sisal, agave, etc.), wood-based plant fibers (e.g., plant fibers harvested from broad-leaved trees and coniferous trees, etc.), and other plant fibers (coconut shell fiber, oil palm empty fruit bunch fiber, rice straw fiber, wheat straw fiber, bamboo fiber, cotton, etc.). These may be used alone or in combination of two or more types.

[0017] The skin material 3 includes a woven fabric 6 with optical fibers 5 woven as constituent threads (see FIG. 7). The woven fabric 6 has a predetermined thickness (for example, 1 mm). A cushion layer 7 is not laminated on the back surface of the woven fabric 6. However, the skin material 3 may include the woven fabric 6 and a thin cushion layer 7 laminated on the back surface of the woven fabric 6. An example of the thin cushion layer 7 is one having a thickness of less than 5 mm, particularly less than 3 mm. The material of the cushion layer 7 is not particularly limited, but a sheet material made of soft polyurethane foam is often used. Other soft resin foams can also be used as long as they have sufficient cushioning properties.

[0018] The optical fiber 5 is of a side-emitting type in which light incident from one end side is emitted from a part or all of the peripheral surface. The skin material 3 is provided with a converging section 8 formed by bundling the optical fibers 5 extending from one edge of the fabric 6 with a sleeve or the like. Light from a light source 9 is incident on the tip of the converging section 8, and the light is emitted from the surface of the fabric 6 by the optical fiber 5, thereby improving the design and presentation effect. The light source 9 is held by a holding section (not shown) provided on the back surface of the base material 2.

[0019] The optical fiber 5 is used as at least one of the warp threads and the weft threads constituting the woven fabric 6. When the optical fiber 5 is used as the warp thread, the ratio of the optical fiber as the warp thread is preferably 10% or more and 90% or less, more preferably 20% or more and 80% or less, and even more preferably 30% or more and 70% or less, when the number of all the warp threads is 100%. When the optical fiber 5 is used as the weft thread, the ratio of the optical fiber 5 as the weft thread is preferably 10% or more and 90% or less, more preferably 20% or more and 80% or less, and even more preferably 30% or more and 70% or less, when the number of all the weft threads is 100%. The diameter of the optical fiber 5 is not particularly limited, but is preferably 0.25 to 3 mm, more preferably 0.1 to 1 mm, from the viewpoint of weaving property and versatility.

[0020] The type of constituent yarns other than the optical fibers 5 constituting the woven fabric 6 (hereinafter also referred to as "other constituent yarns") is not particularly limited, but may be made of natural plant and animal fibers, regenerated fibers such as rayon, semi-synthetic fibers such as acetate, synthetic fibers made of synthetic resins, etc. Examples of resins constituting the synthetic fibers include polyamide resins such as nylon 6 and nylon 66, polyester resins such as polyethylene terephthalate, polybutylene terephthalate, and polytrimethylene terephthalate, polyolefin resins such as high-density polyethylene and polypropylene, and polyacrylic resins.

[0021] In the other constituent yarns constituting the woven fabric 6, the same yarn may be used for the warp yarn and the weft yarn, or different yarns may be used. The other constituent yarns used for the warp yarn may be only one type, or two or more types may be used in combination. Similarly, the other constituent yarns used for the weft yarn may be only one type, or two or more types may be used in combination. The fineness of the other constituent yarns is not particularly limited, but is preferably, for example, 100 dtex or more and 1000 dtex or less, more preferably 200 dtex or more and 700 dtex or less, and even more preferably 300 dtex or more and 500 dtex or less.

[0022] As shown in Figs. 3 and 4, one end of the base material 2 is provided with a wrapping processing section 11 having a curved surface 12 of a predetermined radius (e.g., 5 mm). One edge 12a of the curved surface 12 is continuous with one edge of the front surface of the base material 2 (specifically, the vertical wall portion 2b). The other edge 12b of the curved surface 12 is located behind the back surface of the base material 2 (specifically, the vertical wall portion 2b). The curved surface 12 extends in an elongated shape along one edge of the base material 2. The length of the curved surface 12 in the extension direction is set to a value longer than the radius of the curved surface 12 (for example, a value 5 times or more, particularly 10 times or more, of the radius of the curved surface 12).

[0023] The predetermined radius of the curved surface 12 is, for example, 3 to 20 mm (particularly, 4 to 10 mm). Furthermore, the curved surface 12 may be a curved surface with one predetermined radius, or may be a continuous curved surface in which a plurality of curved surfaces with different predetermined radii are connected together.

[0024] The end portion 3a of the skin material 3 is wound around the winding-up portion 11 so as to fit along the curved surface 12. The end portion 3a of the skin material 3 has a design radius R13 of a predetermined radius (e.g., 6 mm) in the portion that fits along the curved surface 12. The design radius R13 is usually larger than the radius of the curved surface 12. The predetermined radius of the design radius R13 is, for example, 3 to 20 mm (particularly, 4 to 10 mm).

[0025] In this embodiment, an example is shown in which the terminal portion 3b of the skin material 3 from which the optical fiber 5 does not extend (specifically, the terminal portion 3a opposite to the terminal portion 3b (see Figure 7) on the side of the skin material 3 that is connected to the light source 9) is wound around the winding processing portion 11, but this is not limited to this, and for example, a configuration in which the terminal portion 3b of the skin material 3 is wound around the winding processing portion 11 may be adopted.

[0026] The wrapping processing section 11 is composed of a wrapping processing member 15 (see FIG. 6) attached to the base material 2. The wrapping processing member 15 is attached so as to connect to one edge of the base material 2 (specifically, the standing wall portion 2b). Specifically, the wrapping processing member 15 has an arc-shaped portion 16 whose one end side is connected to the tip of the standing wall portion 2b, a first surface portion 17 whose one end side is connected to the other end side of the arc-shaped portion 16 and faces the standing wall portion 2b, and a second surface portion 18 whose one end side is connected to the other end side of the first surface portion 17 and faces the surface portion 2a. The surface of the arc-shaped portion 16 forms a curved surface 12. The second surface portion 18 is placed on a pedestal 14 provided on the surface portion 2a.

[0027] At one end of the arc-shaped portion 16, a step portion 22 is formed to engage with the substrate-side step portion 21 formed at the tip end of the vertical wall portion 2b. At the second surface portion 18, an insertion hole 24 is formed through which a shaft 23a of a fastening part 23 such as a rivet or a screw is inserted. The insertion hole 24 is formed to have a width larger than the diameter of the shaft 23a in the extension direction of the second surface portion 18. Then, the step portions 21 and 22 are engaged with each other, the second surface portion 18 is placed on the pedestal 14, and the wrapping processing member 15 is set on the substrate 2. In this state, the shaft 23a of the fastening part 23 is inserted through the insertion hole 24, and the step portions 21 and 22 are engaged with each other with an appropriate repulsive force, whereby the wrapping processing member 15 is attached to the substrate 2.

[0028] The wrapping process member 15 is provided with a groove 26 into which the tip side of the terminal portion 3a of the skin material 3 is inserted. The groove 26 is arranged so that the tip side of the terminal portion 3a of the skin material 3 can be inserted without bending it. Specifically, the groove 26 is arranged so that the side surface of the groove 26 is continuous with the surface of the first surface portion 17.

[0029] The size (depth, width, etc.) of the groove 26 is not particularly limited, but is preferably set to a value taking into consideration the ease of insertion and retention at the tip end of the skin material 3. For example, the groove 26 can be set so that the end face of the optical fiber 5 constituting the terminal portion 3a of the skin material 3 abuts against the bottom surface of the groove 26.

[0030] 2 and 3, in the mounting structure S for the ornament 1A according to this embodiment, the portion of the skin material 3 that follows the curved surface 12 is butted against a mating part 33. This mounting structure S is a back-to-back structure in which the ornament 1A is mounted from the front surface side of the mating part 33. The mating part 33 has a standing wall portion 22a that is approximately flush with the surface of the portion of the skin material 3 that follows the standing wall portion 2b.

[0031] Next, the effect of the ornament 1A having the above configuration will be described. The ornament 1A is provided with a base material 2 having a plate thickness of 2 mm and a skin material 3 made of a woven fabric 6 having a thickness of 1 mm (i.e., a skin material 3 without a cushion layer). The wrapping processing member 15 is provided with a curved surface 12 having a radius of 5 mm. In this case, a sufficiently large design R13 of a radius of 6 mm is ensured in the portion along the curved surface 12 of the skin material 3. When the light source 9 is operated to emit light from the surface of the skin material 3, no light leakage (i.e., the occurrence of partially bright areas) is observed in the part mating portion between the skin material 3 and the mating part 33.

[0032] As described above, according to the ornament 1A of this embodiment, a wrapping process portion 11 having a curved surface 12 of a predetermined radius is provided at one end of the base material 2, one end edge 12a of the curved surface 12 is continuous with one end edge of the front surface of the base material 2, and the other end edge 12b is located on the back side away from the back surface of the base material 2, and the end portion 3a of the optical fiber skin material 3 is wrapped around the wrapping process portion 11 so as to follow the curved surface 12. As a result, even when an optical fiber skin material 3 having a thin cushion layer or no cushion layer is used, a sufficient size can be ensured as the design R13 of the optical fiber skin material 3 at the part mating portion with the mating part 33. As a result, light leakage from the part mating portion between the optical fiber skin material 3 and the mating part 33 can be suppressed.

[0033] In this embodiment, the wrapping processing section 11 is configured by a wrapping processing member 15 attached to the base material 2. This makes it possible to provide the wrapping processing section 11 having a curved surface 12 suitable for suppressing light leakage at the part mating section and / or suitable for pasting the skin material 3.

[0034] In this embodiment, the winding processing section 11 is provided with a groove 26 into which the tip side of the terminal section 3a of the optical fiber skin material 3 is inserted. This allows the groove 26 to suppress (absorb) light leakage from the end face of the optical fiber 5 constituting the terminal section 3a of the skin material 3, and more effectively suppress light leakage from the component mating section.

[0035] In this embodiment, the curved surface 12 is elongated along one edge of the base material 2. This allows a large attachment margin for the skin material 2 to be secured by the elongated curved surface 12, so that the skin material 2 can be firmly attached to the wrapping processing portion 11.

[0036] In this embodiment, the base material 2 has a surface portion 2a and a vertical wall portion 2b, and one edge 12a of the curved surface 12 is continuous with one edge of the front surface of the vertical wall portion 2b, and the other edge 12b is located on the back side away from the back surface of the vertical wall portion 2b. This makes it possible to effectively suppress light leakage from a part mating portion between the optical fiber skin material 3 wrapped around the tip side of the vertical wall portion 2b of the base material 2 and the mating part 33.

[0037] Furthermore, according to the ornament mounting structure S of this embodiment, the portion of the optical fiber skin material 3 along the curved surface 12 is butted against the mating part 33. This ensures a sufficient size for the design R13 of the optical fiber skin material 3 at the mating part with the mating part 33, even when an optical fiber skin material 3 with a thin cushion layer or no cushion layer is used. As a result, light leakage from the mating part between the optical fiber skin material 3 and the mating part 33 can be suppressed.

[0038] <Modification 1 of the First Embodiment> Next, an ornament 1B according to a first modified example of the first embodiment will be described. Components that are substantially the same as those of the ornament 1A of the first embodiment will be given the same reference numerals and detailed description thereof will be omitted.

[0039] 8, an ornament 1B according to this modification includes a base material 2 and an optical fiber skin material 3. One end of the base material 2 is provided with a wrapping processing portion 11. The wrapping processing portion 11 is composed of a wrapping processing member 15 attached to the base material 2.

[0040] The wrapping process member 15 has an arc-shaped portion 16, a first surface portion 17, and a second surface portion 18. The wrapping process member 15 is provided with a groove 26 into which the tip side of the terminal portion 3a of the skin material 3 is inserted. The groove 26 is disposed on the second surface portion 18.

[0041] <Modification 2 of the First Embodiment> Next, an ornament 1C according to a second modification of the first embodiment will be described. Components that are substantially the same as those of the ornament 1A of the first embodiment will be given the same reference numerals and detailed description thereof will be omitted.

[0042] 9, an ornament 1C according to this modification includes a base material 2 and an optical fiber skin material 3. One end of the base material 2 is provided with a winding processing portion 11. The winding processing portion 11 is composed of a winding processing member 15 attached to the base material 2.

[0043] The wrapping process member 15 has an extension wall portion 19 whose one end side is connected to the tip of the standing wall portion 2b and forms an extension portion of the standing wall portion 2b. Furthermore, the wrapping process member 15 has an arc-shaped portion 16 whose one end side is connected to the other end side of the extension wall portion 19, a first surface portion 17 whose one end side is connected to the other end side of the arc-shaped portion 16 and faces the extension wall portion 19 and the standing wall portion 2b, and a second surface portion 18 whose one end side is connected to the other end side of the first surface portion 17 and faces the surface portion 2a of the base material 2.

[0044] One edge 12a of the curved surface 12 is continuous with one edge of the surface of the extended wall portion 19 (i.e., the extended surface of the surface of the standing wall portion 2b). In other words, one edge 12a of the curved surface 12 is indirectly continuous with one edge of the surface of the standing wall portion 2b. In contrast, in the ornament 1A of the first embodiment, one edge 12a of the curved surface 12 is directly continuous with one edge of the surface of the standing wall portion 2b (see FIG. 3). Here, in the present invention, "one edge of the curved surface is continuous with one edge of the surface of the base material" means that one edge 12a of the curved surface 12 is directly or indirectly continuous with one edge of the surface of the base material 2.

[0045] <Modification 3 of the First Embodiment> Next, an ornament 1D according to a third modification of the first embodiment will be described. Components that are substantially the same as those of the ornament 1A of the first embodiment will be given the same reference numerals and detailed description thereof will be omitted.

[0046] As shown in Fig. 10, an ornament 1D according to this modified example includes a base material 2 and an optical fiber skin material 3. One end of the base material 2 is provided with a winding processing portion 11. The winding processing portion 11 is composed of a winding processing member 15 attached to the base material 2. The winding processing member 15 has an arc-shaped portion 16 and a first surface portion 17. One end side of the arc-shaped portion 16 is fixed to the tip edge of the standing wall portion 2b by welding, adhesion, engagement, or the like.

[0047] <Embodiment 2> Next, an ornament 1E according to a second embodiment will be described. Components that are substantially the same as those of the ornament 1A of the first embodiment will be given the same reference numerals and detailed description thereof will be omitted.

[0048] 11 and 12, an ornament 1E according to this embodiment includes a base material 2 and an optical fiber skin material 3. One end of the base material 2 is provided with a wrapping portion 11 having a curved surface 12 with a predetermined radius (for example, 5 mm).

[0049] The front end of the standing wall portion 2b is formed with a rounded surface 29 (for example, a rounded surface 29 having a radius of 5 mm) that is continuous with the rear surface of the standing wall portion 2b. The rounded surface 29 makes the front end of the standing wall portion 2b tapered. One edge 12a of the curved surface 12 is continuous with one edge of the rounded surface 29.

[0050] The wrapping processing section 11 is composed of ribs 28 integrally molded with the base material 2 (for example, integrally molded by injection molding or the like) (see Figures 13 and 14). A plurality of ribs 28 are arranged at predetermined intervals along one edge of the base material 2. The intervals between the plurality of ribs 28 may be equal or unequal. The ribs 28 are formed in a plate shape. A curved surface 12 is formed on the upper surface of the rib 28. The back surface of the rib 28 is connected to the standing wall portion 2b, and the bottom surface of the rib 28 is connected to the surface portion 2a.

[0051] As described above, the ornament 1E of this embodiment 2 has substantially the same effect as the ornament 1A of embodiment 1, and since the wrapping processing portion 11 is composed of a rib 28 integrally molded with the base material 2, it is possible to reduce the number of parts and make the ornament lighter than the ornament 1A of embodiment 1.

[0052] The present invention is not limited to the above-mentioned embodiment, and various modifications within the scope of the present invention are possible depending on the purpose and use. That is, in the above-mentioned embodiment, ornaments 1A to 1E having a base material 2 with a standing wall portion 2b are exemplified, but the present invention is not limited to this, and for example, as shown in FIG. 15, an ornament 1F having a base material 2 without a standing wall portion 2b may be adopted.

[0053] In addition, in the above embodiment, a structure in which the ornaments 1A to 1E are assembled from the front side of the mating part 33 is exemplified as the ornament assembly structure S, but this is not limited to this, and for example, a structure in which the mating part 33 is placed on the back side of the ornaments 1A to 1E may be adopted.

[0054] In addition, in the above embodiment, the wrapping processing member 15 having the groove 26 is exemplified, but the present invention is not limited to this. For example, a wrapping processing member 15 without the groove 26 may be used.

[0055] Furthermore, in the above embodiment, the ornaments 1A to 1E constituting the vehicle door trim 30 are exemplified as interior parts, but the present invention is not limited thereto, and may be, for example, interior parts constituting vehicle products such as instrument panels, roof trims, floor trims, luggage trims, rear side trims, rear parshells, package trays, pillar garnishes, switch bases, quarter panels, armrests, center consoles, overhead consoles, sun visors, seats, etc. Furthermore, the present invention may be interior parts constituting furniture such as sofas and chairs.

[0056] The above examples are merely illustrative and should not be construed as limiting the present invention. Although the present invention has been described with reference to exemplary embodiments, the words used in describing and illustrating the present invention are understood to be descriptive and exemplary, rather than limiting. As detailed herein, changes may be made within the scope of the appended claims without departing from the scope or spirit of the present invention in its form. Although the present invention has been described herein with reference to specific structures, materials and examples, it is not intended that the present invention be limited to the disclosures therein, but rather that the present invention extends to all functionally equivalent structures, methods and uses within the scope of the appended claims.
