Description

[Technical Field]

[0001] The present invention relates to an interior part, and more particularly to an interior part including a plate-shaped substrate fastened to a base member and a skin material covering the surface of the substrate. [Background technology]

[0002] As a conventional interior part, for example, an ornament 101 constituting a vehicle door trim 141, as shown in FIG. 12, is commonly known. The ornament 101 includes a plate-shaped substrate 102 fastened to a base member 143 and a skin 103 covering the surface of the substrate 102. The skin 103 may be an optical fiber skin having a woven fabric with optical fibers woven therein as constituent threads. The optical fiber skin 103 is often rectangular in plan view to prevent the optical fibers from being cut. When the rectangular optical fiber skin 103 is attached to cover the surface of a non-rectangular substrate 102, for example, as shown in FIG. 13, excess portions 103a and 103b (shown by hatching in the drawing) of the optical fiber skin 103 must be folded back and attached to the back surface of the substrate 102. Unless the excess portions 103a and 103b of the optical fiber skin material 103 are fixed to the rear surface of the base material 102, the optical fiber may be damaged when it is handled.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 03-246133 Summary of the Invention [Problem to be solved by the invention]

[0004] Here, a fastening portion 131 to be fastened to the base member 143 is provided on the back surface of the substrate 102. This fastening portion 131 is required to be located near a parting edge D1 of the ornament 101 design (i.e., the mating portion between the ornament 101 and the upper board 144; the portion of the ornament 101 to which the upper board 144 applies a pressing force). However, in the ornament 101 described above, the excess portion 103a of the optical fiber skin 103 is folded back and attached to the back surface of the substrate 102, so the fastening portion 131 cannot be located in the area corresponding to the overlapping portion. In other words, the fastening portion 131 cannot be located near the outer edge of the substrate 102 and must be located away from the parting edge D1 of the ornament 101 design. This problem occurs not only in the ornament 101 constituting the vehicle door trim 141 but also in interior components in which the excess portion of the optical fiber skin is folded back to the back surface of the substrate.

[0005] Patent Document 1 describes a technique in which an excess portion of the skin material is folded back onto the back surface of the base material and a locking plate provided on the excess portion is locked by a locking means provided on the back surface of the base material, but it does not describe any technique for reducing the area where the excess portion of the skin material is folded back onto the back surface of the base material.

[0006] The present invention has been made in consideration of the above-mentioned current situation, and aims to provide an interior part that can position the fastening portion for the base member closer to the outer edge of the back surface of the base material by reducing the area where the excess portion of the skin material is folded back onto the back surface of the base material, thereby bringing it closer to the edge of the design of the interior part. [Means for solving the problem]

[0007] In order to solve the above problem, the invention described in claim 1 is an interior part comprising a plate-shaped substrate fastened to a base member and a skin material covering the surface of the substrate, wherein the skin material has a fabric with optical fibers woven into it as constituent threads, the skin material is provided with folding sections that are folded into multiple pieces and folded back onto the back surface of the substrate, and a clip body that clamps the folding sections is provided on the back surface of the substrate. The invention as set forth in claim 2 is the invention as set forth in claim 1, wherein a fastening portion that is fastened to the base member is provided on the clip body. The invention described in claim 3 is the invention described in claim 1 or 2, wherein the clip body comprises a first wall portion raised on the back surface of the base material, a second wall portion extending from the raised end of the first wall portion toward the outer edge of the base material, and a third wall portion extending from the end of the second wall portion closer to the outer edge of the base material toward the back surface of the base material, and gaps are formed between the third wall portion and each tip of the convex portion protruding from the back surface of the base material, and the folded portion is inserted into the clip body through the gaps to be clamped between the second wall portion and the back surface of the base material. The invention as set forth in claim 4 is the invention as set forth in claim 1, wherein a plurality of the clip bodies are provided along at least one side of the base material. The invention described in claim 5 is summarized as an ornament constituting a door trim for a vehicle in the invention described in claim 1. [Effects of the Invention]

[0008] According to the interior part of the present invention, the skin material has a woven fabric with optical fibers woven as constituent threads, and the skin material has a folded portion that is folded into multiple layers and folded back onto the back surface of the base material, and a clip body is provided on the back surface of the base material to clamp the folded portion. This makes it possible to reduce the area where the excess portion of the skin material is folded back onto the back surface of the base material. Therefore, the fastening portion for the base member can be positioned closer to the outer edge of the back surface of the base material, making it possible to approach the border of the design of the interior part. Furthermore, if a fastening portion that is fastened to the base member is provided on the clip body, the fastening portion can be positioned closer to the border of the design of the interior component. Furthermore, the clip body has a first wall portion, a second wall portion, and a third wall portion, and a gap is formed between the third wall portion and each tip end of the convex portion protruding from the back surface of the base material, and when the folded portion is inserted into the clip body through the gap and clamped between the second wall portion and the back surface of the base material, the folded portion can be clamped easily and firmly. Furthermore, when a plurality of clip bodies are provided along at least one side of the base material, the long folded portion can be clamped without dangling. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0010] The matters set forth herein are for illustrative purposes only and are intended to provide an illustrative description of the embodiments of the present invention, with the aim 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 regard, 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, taken together with the drawings, will make clear to those skilled in the art how some forms of the present invention may be actually embodied.

[0011] As shown in FIGS. 1 and 2, the interior part 1 according to this embodiment includes a plate-shaped substrate 2 fastened to a base member 43 and a skin material 3 covering the surface of the substrate 2, the skin material 3 having a woven fabric 7 with optical fibers 4 woven therein as constituent threads, the skin material 3 having folding portions 11 that are folded into multiple pieces and folded back onto the back surface of the substrate, and a clip body 15 that clamps the folding portions 11 is provided on the back surface of the substrate 2.

[0012] The shape of the substrate 2 is not particularly limited. The substrate 2 may have a planar shape other than a rectangular shape (including a square shape). Specifically, the substrate 2 may be formed into an elongated shape, and may have a planar shape in which the width in the direction perpendicular to the elongated direction gradually changes along the elongated direction (see FIG. 5).

[0013] The back surface of the substrate 2 may be provided with fastening portions 18 (specifically, fastening bosses) that are fastened to the base member 43 (see FIG. 6). A plurality of these fastening portions 18 may be provided along at least one side 2a, 2b of the substrate 2. The fastening method between the fastening portions 18 and the base member 43 is not particularly limited, and one or a combination of two or more of screw fastening, fitting fastening, fastener fastening, adhesive fastening, etc. may be appropriately selected. Specifically, the fastening portions 18 and the mounting portions 19 provided on the base member 43 may be fastened with screws. The fastening portions 18 are required to be located near the parting lines D1, D2 of the design of the interior part 1 (i.e., the mating portions between the interior part 1 and other interior parts 44, 45; the portions of the interior part 1 where pressure from the other interior parts 44, 45 is applied).

[0014] The material of the substrate 2 is not particularly limited. 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 may contain the above-mentioned thermoplastic resin and reinforcing fibers. The reinforcing fibers may be inorganic fibers (glass fibers, carbon fibers, etc.) or 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. Furthermore, 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 collected from broad-leaved trees and coniferous trees, etc.), and other plant fibers (coconut husk 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. The material of the base member is not particularly limited. The base member may be made of the same material as the above-mentioned substrate.

[0015] The skin material 3 covers all or part of the surface of the base material 2. The skin material 3 may or may not be adhered to the surface of the base material 2 with an adhesive or the like. The skin material 3 has a woven fabric 7 into which optical fibers 4 are woven as constituent threads. The skin material 3 may also have the woven fabric 7 and a cushioning layer 8 laminated on the back surface of the woven fabric 7 (see FIG. 4). The material of the cushioning layer 8 is not particularly limited, but a sheet material made of soft polyurethane foam is often used. Other soft resin foams may also be used as long as they have sufficient cushioning properties.

[0016] The skin material 3 can have a planar rectangular shape (including a square shape) so as to prevent the optical fiber 4 from being cut (see FIG. 5). When this planar rectangular skin material 3 is used to cover the surface of the non-planar rectangular substrate 2, excess portions 3a, 3b of the skin material 3 are generated along at least one side 2a, 2c of the substrate 2. These excess portions 3a, 3b of the skin material 3 are usually formed in an elongated shape along one side 2a, 2b of the substrate 2, and the size of the excess portions 3a, 3b in the direction perpendicular to the elongated direction gradually changes along the elongated direction.

[0017] The woven fabric 7 is a fabric woven with constituent yarns (warp and weft yarns), and the weave is not particularly limited. Specifically, various weaves, such as plain weave, twill weave, and satin weave, can be used. Optical fibers 4 are at least used as constituent yarns of the woven fabric 7 (see FIG. 4 ). Various optical fibers 4 having a core-sheath structure (multilayer structure) with a core (core layer) and a sheath (clad layer), in which the refractive indexes of the core layer and the clad layer are different, can be used. The optical fibers 4 may be side-emitting optical fibers 4 in which light incident on one end is emitted from part or all of the circumferential surface, or edge-emitting optical fibers 4 in which light incident on one end is emitted from the other end. In particular, when side-emitting optical fibers 4 are used, light from the light source 6 can be emitted from the surface of the woven fabric 7 (i.e., the covering material 3) in which the optical fibers 4 are woven, thereby further enhancing the design and dramatic effect.

[0018] The optical fibers 4 are used as at least one of the warp and weft threads constituting the woven fabric, and can be used as the weft thread in particular. When the optical fibers 4 are used as the warp threads, the proportion of the optical fibers 4 as the warp threads is preferably 10% to 90% of the total number of warp threads, more preferably 20% to 80% of the total number of weft threads, and even more preferably 30% to 70% of the total number of weft threads. When the optical fibers 4 are used as the weft threads, the proportion of the optical fibers 4 as the weft threads is preferably 10% to 90% of the total number of weft threads, more preferably 20% to 80% of the total number of weft threads, and even more preferably 30% to 70% of the total number of weft threads. The diameter of the optical fibers 4 is not particularly limited, but is preferably 0.25 to 3 mm, more preferably 0.1 to 1 mm, from the viewpoints of weaving ability and versatility.

[0019] The type of constituent yarns other than the optical fibers 4 that make up the woven fabric 7 (hereinafter also referred to as "other constituent yarns") is not particularly limited, but may be made from natural plant and animal fibers, regenerated fibers such as rayon, semi-synthetic fibers such as acetate, synthetic fibers made of synthetic resin, etc. Examples of resins that make up 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.

[0020] Of the other constituent yarns that make up the woven fabric 7, the same yarns may be used for the warp and weft yarns, or different yarns may be used. The other constituent yarns used for the warp yarns may be of only one type, or two or more types may be used in combination. Similarly, the other constituent yarns used for the weft yarns may be of 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 to 1000 dtex, more preferably 200 dtex to 700 dtex, and even more preferably 300 dtex to 500 dtex.

[0021] The covering material 3 has a folding portion 11 that is folded into multiple pieces and folded back onto the back surface of the base material 2 (see FIG. 8). The folding portion 11 may be formed by folding the excess portion 3a of the covering material 3 into multiple pieces and then folding back onto the back surface of the base material 2, or by folding back the excess portion 3a of the covering material 3 onto the back surface of the base material 2 and then folding it into multiple pieces. Furthermore, the folding portion 11 may be formed so that the back surfaces (i.e., non-design surfaces) of the excess portions 3a of the covering material 3 are in contact with each other, or so that the surfaces (i.e., design surfaces) of the excess portions 3a of the covering material 3 are in contact with each other, and when folded into three or more pieces, a combination of the above-mentioned forms may be used.

[0022] The folded portion 11 may be formed in an elongated shape along one side 2a of the base material 2. The folded portion 11 may be folded with a number of folds and / or a folding width (i.e., the width in a direction perpendicular to the longitudinal direction of the folded portion 11) that corresponds to the size of the excess portion 3a of the skin material 3. Specifically, the folded portion 11 may have, along its longitudinal direction, a portion folded with a first number of folds and a portion folded with a second number of folds that is greater than the first number of folds. Furthermore, the folded portion 11 may have, along its longitudinal direction, a portion folded with a first folding width and a portion folded with a second folding width that is greater than the first folding width.

[0023] Although clip body 15 may be attached to the back surface of base material 2 separately from base material 2, it is preferable to mold clip body 15 integrally with base material 2 (specifically, integrally molded) from the viewpoint of reducing the number of parts. While the number of clip bodies 15 is not particularly limited, it is preferable that a plurality of clip bodies 15 be provided along at least one side 2a of base material 2 to clamp elongated folded portion 11 (see FIG. 6). Pitch intervals P1 and P2 between adjacent clip bodies among multiple clip bodies 15A-15C can be set to values ​​that prevent elongated folded portion 11 clamped by each clip body from swaying (see FIG. 5). Furthermore, the portion of folded portion 11 clamped by one adjacent clip body among multiple clip bodies 15A-15C can differ in the number of folds and / or the folding width (see FIG. 8). When inserting the folding portion 11 into multiple clip bodies 15A to 15C, the folding portion 11 may be inserted sequentially into each clip body 15A to 15C, or the folding portion 11 may be inserted simultaneously into at least two or more clip bodies.

[0024] 7 and 8, the clip body 15 includes a first wall portion 21 that is raised on the back surface of the base material 2, a second wall portion 22 that extends from the raised end of the first wall portion 21 toward the outer edge (i.e., the end) of the base material 2, and a third wall portion 23 that extends from the end (i.e., the tip) of the second wall portion 22 that is closer to the outer edge of the base material 2 toward the back surface of the base material 2, and a gap C can be formed between the third wall portion 23 and each tip of a protrusion 24 that protrudes from the back surface of the base material 2. The folded portion 11 can be sandwiched between the second wall portion 22 and the back surface of the base material 2 by being inserted into the clip body 15 (specifically, the space S surrounded by the first wall portion 21, the second wall portion 22, the third wall portion 23, the protrusion 24, and the back surface of the base material 2) through the gap C. The third wall portion 23 may be configured so that its tip portion faces the inner portion of the convex portion 24 on the back surface of the base material 2 (see Figure 11(b)), but from the standpoint of the clamping ability of the folding portion 11, it is preferable that the third wall portion 23 is configured so that its tip portion faces the tip portion of the convex portion 24 (see Figure 3).

[0025] The size of the gap C is not particularly limited as long as it forms an insertion opening for the folded portion 11. The distance C1 of the gap C can be set to a value that allows the folded portion 11 to be inserted into the clip body 15 in a state where it is collapsed in the thickness direction and that prevents the inserted folded portion 11 (i.e., the folded portion 11 expanded from the collapsed state) from slipping out. Furthermore, the distance C1 of the gap C can be set to a value smaller than the thickness of the non-folded portion 12 (i.e., the portion that is not folded into multiple layers and is folded back to the back surface of the base material 2) that is connected to the folded portion 11 of the cover material 3. In this case, when the folded portion 11 is inserted into the clip body 15, the non-folded portion 12 can be sandwiched between the third wall portion 23 and the tip ends of the protrusion 24. Furthermore, the vertical width L of the space S can be set to a value substantially equal to the folded width of the folded portion 11 inserted into the clip body 15. Furthermore, the height H of the space S can be set to a value smaller than the thickness of the folded portion 11 inserted into the clip body 15.

[0026] To increase the strength of the clip body 15, the first wall portion 21 and the second wall portion 22 are preferably connected by a connecting wall 26 having an arc-shaped cross section. The second wall portion 22 and the third wall portion 23 are preferably connected by a connecting wall 27 having an arc-shaped cross section. The outer surface of the first wall portion 21 (i.e., the surface facing away from the space S) and the back surface of the base material 2 are preferably connected by a reinforcing rib 28. The reinforcing ribs 28 may be disposed at both ends of the first wall portion 21 in the width direction (i.e., the direction along one side 2 a of the base material 2). The inner surface of the second wall portion 22 (i.e., the surface forming the space S) and the inner surface of the third wall portion 23 (i.e., the surface forming the space S) are preferably connected by a reinforcing rib 29. The reinforcing rib 29 may be disposed in the middle of the second wall portion 22 and the third wall portion 23 in the width direction (i.e., the direction along one side 2 a of the base material 2).

[0027] There are no particular limitations on the location of the protrusions 24. The protrusions 24 may be arranged in a position spaced apart from the outer edge on the back surface of the base material 2 (see FIG. 11(a)), but are preferably arranged on the outer edge side of the back surface of the base material 2 in order to bring the fastening portion 18 closer to the parting edge D1 of the design of the interior component 1 (see FIG. 3). In this case, the protrusions 24 can be formed by bending the outer edge of the base material 2 toward the back surface.

[0028] The protrusion 24 can extend linearly along one side 2a of the base material 2. The length of the linear extension of this protrusion 24 is not particularly limited. From the viewpoint of the clamping ability of the folded portion 11, the length of the protrusion 24 is preferably equal to or greater than the width of the third wall portion 23 of the clip body 15 (i.e., the width in the direction along one side 2a of the base material 2). In particular, from the viewpoint of the strength of the base material 2, it is preferable that the protrusion 24 has approximately the same length as one side 2a of the base material 2 (see FIG. 6).

[0029] The fastening portion 18, which is fastened to the base member 43, may be provided on the clip body 15 (see FIGS. 3 and 7). The fastening portion 18 may be disposed on a base portion 34 (specifically, the portion spanning the first wall portion 21 and the second wall portion 22) of the clip body 15 that rises above the back surface of the substrate 2 (see FIGS. 3 and 7). To increase the strength of the clip body 15 and the fastening portion 18, a reinforcing rib 35 is preferably used to connect the outer surface of the fastening portion 18 to the back surface of the substrate 2. An end of the reinforcing rib 35 can abut against the surface of the base member 43 when the fastening portion 18 is fastened to the base member 43. Furthermore, a reinforcing rib 36 is preferably used to connect the outer surface of the fastening portion 18 to the outer surface of the clip body 15 (specifically, the outer surface of the first wall portion 21) and the back surface of the substrate 2. An end of the reinforcing rib 36 can abut against the surface of the base member 43 when the fastening portion 18 is fastened to the base member 43. The clip body 15, the fastening portion 18, and the reinforcing ribs 35, 36 can be integrally molded (specifically, integrally molded) with the base material 2.

[0030] The fastening portion 18 can be disposed in a portion of the clip body 15 closer to the outer edge of the base material 2 than a base portion 34 that rises on the back surface of the base material 2 (specifically, a middle portion of the second wall portion 22 in the vertical width direction perpendicular to one side 2a of the base material 2) (see FIGS. 9 and 10 ). To increase the strength of the clip body 15 and the fastening portion 18, the outer surface of the fastening portion 18, the outer surface of the clip body 15 (specifically, the outer surface of the second wall portion 22 and the outer surface of the first wall portion 21), and the back surface of the base material 2 are preferably connected by a reinforcing rib 38. An end of this reinforcing rib 38 can abut against the surface of the base member 43 when the fastening portion 18 is fastened to the base member 43. Furthermore, the outer surface of the fastening portion 18 and the outer surface of the clip body 15 (specifically, the outer surface of the second wall portion 22) are preferably connected by a reinforcing rib 39. An end of this reinforcing rib 39 can abut against the surface of the base member 43 when the fastening portion 18 is fastened to the base member 43. The clip body 15, the fastening portion 18, and the reinforcing ribs 38, 39 can be integrally molded (specifically, integrally molded) with the base material 2.

[0031] The use of this interior part is not particularly limited. Examples of this interior part include vehicle interior parts that constitute door trim, instrument panel, roof trim, floor trim, luggage trim, rear side trim, rear parshell, package tray, pillar garnish, switch base, quarter panel, armrest, center console, overhead console, sun visor, and seat for a vehicle. Furthermore, this interior part may be an interior part that constitutes furniture such as a sofa or chair. The surface (i.e., the design surface) of the end of this interior part 1 can be in contact with the end of another interior part 44 (see FIG. 3). This contact portion forms a parting edge D1 of the design of the interior part 1. [Example]

[0032] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the accompanying drawings. In the present embodiment, an ornament constituting a door trim for a vehicle is exemplified as an "interior part" according to the present invention.

[0033] 1 and 2, a vehicle door trim 41 includes a plate-shaped trim main body 42 that covers a metal inner panel (not shown) from the inside of the vehicle compartment, and a base member 43. The trim main body 42 includes an ornament 1, an upper board 44, and a lower board 45 that form a design surface on the inside of the vehicle compartment.

[0034] The ornament 1 according to this embodiment includes a plate-shaped substrate 2 fastened to a base member 43, and a skin material 3 covering the surface of the substrate 2. The ornament 1 is disposed between an upper board 44 and a lower board 45 in the vertical direction. The lower end of the upper board 44 abuts against the surface of the upper end of the front surface of the ornament 1 (i.e., the design surface), and this abutting portion forms a parting edge D1 of the design of the ornament 1. The upper end of the lower board 45 abuts against the surface of the lower end of the front surface of the ornament 1 (i.e., the design surface), and this abutting portion forms a parting edge D2 of the design of the ornament 1. The base member 43 is disposed so as to face the back surface of the ornament 1.

[0035] The base material 2 is formed in an elongated shape in the vehicle longitudinal direction A, and has a planar shape in which the plate width in the vertical direction gradually decreases toward the front of the vehicle (see FIG. 5). The back surface of the base material 2 is provided with fastening portions 18 (specifically, fastening bosses) that are fastened to the base member 43 (see FIG. 6). A plurality of fastening portions 18 are provided along the upper side portion 2a and the lower side portion 2b of the base material 2. Furthermore, the fastening portions 18 and mounting portions 19 provided on the base member 43 are fastened with screws (see FIG. 7). In addition, the back surface of the base material 2 is provided with a protrusion 24 that extends linearly along the upper side portion 2a. The protrusion 24 has approximately the same length as the upper side portion 2a.

[0036] The skin material 3 comprises a woven fabric 7 into which side-emitting optical fibers 4 are woven as constituent threads, and a cushion layer 8 laminated on the back surface of the woven fabric 7 (see FIG. 4). Light from a light source 6 is emitted from the surface of the woven fabric 7 (i.e., the skin material 3) via these optical fibers 4, thereby further enhancing the design and dramatic effect. Note that bundling sections 5 for the optical fibers 4 are provided on both ends of the skin material 3 in a predetermined direction (specifically, the vehicle longitudinal direction A), and light from the light source 6 is incident on each bundling section 5 (see FIG. 5). The light source 6 is held by a holder (not shown) provided on the back surface of the base material 2.

[0037] The skin material 3 has a rectangular planar shape to prevent the optical fiber 4 from being cut (see FIG. 5). When this rectangular planar skin material 3 is used to cover the surface of the non-rectangular planar substrate 2, excess portions 3a and 3b of the skin material 3 are generated along the upper edge 2a and side edge 2c of the substrate 2. The excess portions 3a and 3b of the skin material 3 are formed in an elongated shape along the upper edge 2a and side edge 2b of the substrate 2, and the size of the excess portions 3a and 3b in the direction perpendicular to the elongated direction gradually changes along the elongated direction.

[0038] The skin material 3 has a folded portion 11 that is folded into multiple pieces and folded back onto the back surface of the base material 2 (see FIG. 8). This folded portion 11 is formed in a long shape along the upper side 2a of the base material 2 by folding the excess portion 3a of the skin material 3. The excess portion 3b of the skin material 3 along the side side 2c of the base material 2 is not folded, but is folded back onto the back surface of the base material 2 and attached to the back surface of the base material 2 with an adhesive or the like.

[0039] Clip bodies 15 that clamp the folded portion 11 are provided on the back surface of the base material 2 (see FIG. 6). A plurality of clip bodies 15 (three in FIG. 6) are provided along the upper side 2a of the base material 2 to clamp the long folded portion 11. The interval between adjacent clip bodies 15 is set to a value that prevents the long folded portion 11 clamped by each clip body 15 from dangling. More specifically, the pitch distance P1 between each clip body 15A and 15B is approximately 140 mm, the pitch distance P2 between each clip body 15B and 15C is approximately 150 mm, and the distance P3 between clip body 15C and the side of the base material 2 is approximately 100 mm (see FIG. 5).

[0040] As shown in FIGS. 7 and 8, the clip bodies 15A to 15C each include a first wall portion 21, a second wall portion 22, and a third wall portion 23. The first wall portion 21 is raised on the back surface of the base material 2. The second wall portion 22 extends from the raised end of the first wall portion 21 toward the outer edge of the base material 2. The third wall portion 23 extends from the end of the second wall portion 22 closer to the outer edge of the base material 2 toward the back surface of the base material 2 (specifically, the protrusion 24). A gap C that forms an insertion opening for the folded portion 11 is formed between the third wall portion 23 and the tip of the protrusion 24. The folded portion 11 is inserted into the clip bodies 15A to 15C (specifically, into a space S surrounded by the first wall portion 21, the second wall portion 22, the third wall portion 23, the protrusion 24, and the back surface of the base material 2) through the gap C, thereby being sandwiched between the second wall portion 22 and the back surface of the base material 2.

[0041] The first wall portion 21 and the second wall portion 22 are connected by a connecting wall 26 having an arc-shaped cross section. The second wall portion 22 and the third wall portion 23 are connected by a connecting wall 27 having an arc-shaped cross section. The outer surface of the first wall portion 21 and the back surface of the base material 2 are connected by a reinforcing rib 28. These reinforcing ribs 28 are respectively arranged at both ends of the first wall portion 21 in the width direction. Furthermore, the inner surface of the second wall portion 22 and the inner surface of the third wall portion 23 are connected by a reinforcing rib 29. This reinforcing rib 29 is arranged in the middle of the second wall portion 22 in the width direction.

[0042] As shown in FIGS. 3 and 7 , the clip body 15A is provided with the fastening portion 18 (specifically, a fastening boss) that is fastened to the base member 43. The fastening portion 18 and the mounting portion 19 provided on the base member 43 are fastened together with screws 33. The fastening portion 18 is disposed at a base portion 34 (specifically, a portion spanning the first wall portion 21 and the second wall portion 22) that rises up from the back surface of the base member 2 of the clip body 15A. The outer peripheral surface of the fastening portion 18 and the back surface of the base member 2 are connected by a reinforcing rib 35. The outer peripheral surface of the fastening portion 18, the outer surface of the first wall portion 21, and the back surface of the base member 2 are connected by a reinforcing rib 36. The ends of these reinforcing ribs 35 and 36 abut against the surface of the base member 43 when the fastening portion 18 is fastened to the base member 43.

[0043] Here, the size of the gap C and space S between each of the clip bodies 15A to 15C will be described. In this embodiment, the thickness of the skin material 3 excluding the folded portion 11 is approximately 5.6 mm, and by compressing the folded portion 11 in the thickness direction, the thickness of that portion becomes approximately 2 mm, and by compressing the folded portion 11 in the thickness direction, the thickness of that portion becomes approximately 3 mm.

[0044] 8, in clip body 15A, the distance C1 of gap C is approximately 3 mm, the vertical width L of space S is approximately 15 mm, and the height H of space S is approximately 10 mm so that a portion of folding portion 11 folded into two can be clamped. In clip body 15B, the distance C1 of gap C is approximately 3 mm, the vertical width L of space S is approximately 20 mm, and the height H of space S is approximately 10 mm so that a portion of folding portion 11 folded into two can be clamped. In clip body 15C, the distance C1 of gap C is approximately 5 mm, the vertical width L of space S is approximately 20 mm, and the height H of space S is approximately 15 mm so that a portion of folding portion 11 folded into three can be clamped.

[0045] Next, the effects of the ornament 1 configured as described above will be described. When the folded portion 11, which has been crushed in the thickness direction, is inserted into the clip body 15 through the gap C, the folded portion 11 causes the second wall portion 22 to deform in a direction away from the back surface of the base material 2 (i.e., in a direction widening the gap C), with the upper end of the first wall portion 21 as a fulcrum, and the folded portion 11 passes through the gap C. When the folded portion 11 is completely inserted into the clip body 15, the folded portion 11 expands from its crushed state and is sandwiched between the second wall portion 22 and the reinforcing rib 29 and the back surface of the base material 2. Furthermore, the non-folded portion 12 connected to the folded portion 11 is sandwiched between the tip ends of the third wall portion 23 and the protrusion 24. In this sandwiched state, the third wall portion 23 and the protrusion 24 prevent the folded portion 11 from slipping out of the clip body 15.

[0046] As described above, in the ornament 1 of this embodiment, the skin material 3 has the woven fabric 7 with the optical fibers 4 woven as constituent threads, and the skin material 3 is provided with the folded portion 11 that is folded into multiple layers and folded back onto the back surface of the base material 2, and clip bodies 15A to 15C that clamp the folded portion 11 are provided on the back surface of the base material 2. This makes it possible to reduce the area where the excess portion 3a of the skin material 3 is folded back onto the back surface of the base material 2. Therefore, the fastening portion 18 for the base member 43 can be positioned closer to the outer edge of the back surface of the base material 2, and can be brought closer to the partings D1 and D2 of the ornament 1 design.

[0047] In this embodiment, the clip body 15A is provided with a fastening portion 18 that is fastened to the base member 43. This allows the fastening portion 18 to be positioned closer to the parting edge D1 of the ornament 1 design.

[0048] Furthermore, in this embodiment, fastening portion 18 is disposed at base portion 34 of clip body 15A that rises above the back surface of base material 2. This allows fastening portion 18 to be properly fastened to base member 43 even if base material 2 is made of a material such as polypropylene and clip body 15A, which is integrally molded with base material 2, is prone to bending.

[0049] In this embodiment, clip bodies 15A to 15C include first wall portion 21, second wall portion 22, and third wall portion 23, and gaps C are formed between third wall portion 23 and the tips of protrusions 24 protruding from the back surface of base material 2. Folded portion 11 is inserted into clip bodies 15A to 15C through gaps C, and is thereby clamped between second wall portion 22 and the back surface of base material 2. This allows folded portion 11 to be clamped easily and firmly.

[0050] In this embodiment, the inner surface of the second wall portion 22 and the inner surface of the third wall portion 23 are connected by a reinforcing rib 29. This allows the folding portion 11 to be more firmly clamped by the pressure of the reinforcing rib 29.

[0051] Furthermore, in this embodiment, a plurality of clip bodies 15A to 15C are provided along the upper side portion 2a of the base material 2. This allows the long folded portion 11 to be clamped without dangling.

[0052] Next, an ornament according to a modified example will be described, but parts having the same configuration as the ornament 1 described above will be given the same reference numerals and detailed description will be omitted.

[0053] 9 and 10, a fastening portion 18 (i.e., a fastening boss) is provided on the clip body 15A to be fastened to the base member 43. This fastening portion 18 and an attachment portion 19 provided on the base member 43 are fastened together with a screw 33. The fastening portion 18 is disposed in a portion of the clip body 15A closer to the outer edge of the base material 2 than a base portion 34 that rises up on the back surface of the base material 2 (specifically, the middle portion in the vertical width direction of the second wall portion 22).

[0054] The outer peripheral surface of the fastening portion 18, the outer surface of the clip body 15A (specifically, the outer surface of the second wall portion 22 and the outer surface of the first wall portion 21), and the back surface of the base material 2 are connected by reinforcing ribs 38. Furthermore, the outer peripheral surface of the fastening portion 18 and the outer surface of the clip body 15A (specifically, the outer surface of the second wall portion 22) are connected by reinforcing ribs 39. The ends of these reinforcing ribs 38, 39 abut against the surface of the base member 43 when the fastening portion 18 is fastened to the base member 43.

[0055] According to this clip body 15A, when the material of the base material 2 is ABS resin or the like and the clip body 15A integrally molded with the base material 2 is not easily bent, the fastening portion 18 to the base member 43 can be brought closer to the parting edge D1 of the design of the ornament 1.

[0056] The present invention is not limited to the above-described embodiment, and various modifications may be made within the scope of the present invention depending on the purpose and application. In other words, the above-described embodiment illustrates the clip body 15 having the first wall portion 21, the second wall portion 22, and the third wall portion 23, and forming the gap C between the third wall portion 23 and the tip end of the protrusion 24. However, the present invention is not limited to this. For example, as shown in FIG. 11( c), the clip body 15 may have the first wall portion 21 and the second wall portion 22 without the third wall portion 23, and form the gap C between the second wall portion 22 and the tip end of the protrusion 24.

[0057] In the above embodiment, the fastening portion 18 is provided on one clip body 15A among the plurality of clip bodies 15A to 15C, but the present invention is not limited to this. For example, the fastening portion 18 may be provided on at least two or more clip bodies among the plurality of clip bodies 15A to 15C. Furthermore, the clip body 15A may be provided with an abutting portion that abuts against the base member 43. Furthermore, the plurality of clip bodies 15A to 15C may not be provided with the fastening portion 18 or the abutting portion.

[0058] The foregoing examples are for illustrative purposes only and are not to be construed as limiting the invention. While the invention has been described with reference to exemplary embodiments, it is understood that the language used in describing and illustrating the invention is descriptive and exemplary, rather than limiting. As detailed herein, changes may be made within the purview of the appended claims without departing from the scope or spirit of the invention in its form. While the description of the invention has referred to specific structures, materials, and examples, it is not intended that the invention be limited to the disclosures therein; rather, the invention is intended to cover all functionally equivalent structures, methods, and uses within the scope of the appended claims.
