Description

Technical Field

[0001] The present invention relates to an interior trim component, and more specifically, to an interior trim component having a plate-shaped substrate fastened to a base member and a skin component covering the surface of the substrate. Background Technology

[0002] For example, such as Figure 12 As shown, a decorative element 101 constituting a vehicle door trim panel 141 is generally known as a conventional interior trim component. This decorative element 101 includes: a plate-shaped substrate 102 fastened to a base member 143; and a skin member 103 covering the surface of the substrate 102. As this skin member 103, sometimes an optical fiber skin member is used, which is a fabric with woven optical fibers as constituent threads. This optical fiber skin member 103 mostly uses a planar rectangular shape to prevent the optical fibers from being cut. When the planar rectangular shape optical fiber skin member 103 is pasted onto the surface of a non-planar rectangular substrate 102, for example, as... Figure 13 As shown, the remaining portions 103a and 103b (shown as shaded in the figure) of the fiber optic sheath 103 need to be folded back and glued to the back of the substrate 102. If the remaining portions 103a and 103b of the fiber optic sheath 103 are not fixed to the back of the substrate 102, the fiber optic cable may be damaged during processing, etc.

[0005] Patent Document 1: Japanese Patent Application Publication No. 03-246133 Summary of the Invention

[0006] The problem the invention aims to solve

[0007] Here, a fastening part 131 for fastening to the base member 143 is provided on the back side of the substrate 102. This fastening part 131 is required to be located near the boundary D1 on the appearance of the trim 101 (i.e., the mating portion of the trim 101 and the upper panel 144; the portion of the trim 101 where pressure from the upper panel 144 is applied). However, in the trim 101 described above, the remaining portion 103a of the fiber optic sheath 103 is folded back and adhered to the back side of the substrate 102. Therefore, the fastening part 131 cannot be provided in the area corresponding to this adhesion allowance. That is, the fastening part 131 cannot be positioned on the side of the substrate 102 near its outer edge, but must be located far from the boundary D1 on the appearance of the trim 101. This problem arises not only in the trim 101 constituting the vehicle door interior panel 141, but also in interior trim components where the remaining portion of the fiber optic sheath is folded back towards the back of the substrate.

[0008] Furthermore, Patent Document 1 describes a technique for folding the remaining portion of the skin piece back toward the back side of the substrate and securing the locking plate provided on the remaining portion using a locking member provided on the back side of the substrate. However, no technique is described for reducing the folded area of ​​the remaining portion of the skin piece folded back toward the back side of the substrate.

[0009] The present invention was made in view of the above-mentioned situation, and its object is to provide an interior trim component that, by reducing the folded-back area of ​​the remaining part of the skin component folded back to the back of the substrate, can arrange the fastener relative to the base member on the back of the substrate near the outer edge so that it is close to the visual boundary of the interior trim component.

[0010] Solution for solving the problem

[0011] To solve the above problems, the invention described in technical solution 1 is an interior trim component comprising: a plate-shaped substrate fastened to a base member; and a skin component covering the surface of the substrate. The main feature is that the skin component has a fabric woven with optical fibers as constituent threads, and the skin component is provided with folded portions that are folded into multiple sheets and folded back to the back of the substrate. A clamping member for holding the folded portions is provided on the back of the substrate.

[0012] The invention described in technical solution 2 is based on the invention described in technical solution 1, and its main purpose is to provide a fastening part on the clamping component that is fastened to the base component.

[0013] The invention described in technical solution 3 is based on the invention described in technical solution 1 or 2. Its main feature is that the clamping member includes: a first wall portion that stands upright on the back side of the substrate; a second wall portion that extends from the upright end of the first wall portion toward the outer edge of the substrate; and a third wall portion that extends from the end of the second wall portion near the outer edge of the substrate toward the back side of the substrate. A gap is formed between the front end of the third wall portion and the front end of the protrusion provided on the back side of the substrate. The folded portion is inserted into the clamping member through the gap and is clamped between the second wall portion and the back side of the substrate.

[0014] The invention described in technical solution 4 is based on the invention described in technical solution 1, and its main feature is that the clamping components are provided in a plurality along at least one side of the substrate.

[0015] The invention described in technical solution 5 is based on the invention described in technical solution 1, and its main purpose is that the interior component is a decoration constituting the interior panel of a vehicle door.

[0016] The effects of the invention

[0017] According to the interior trim component of the present invention, the outer skin component has a fabric woven with optical fibers as constituent threads, and the outer skin component is provided with folded portions that are folded into multiple sheets and folded back to the back of the substrate. A clamping member is provided on the back of the substrate to hold the folded portions. This reduces the folded-back area of ​​the remaining portion of the outer skin component that folds back to the back of the substrate. Consequently, the fastening portion relative to the base member can be positioned on the back of the substrate near the outer edge and brought close to the visual boundary of the interior trim component.

[0018] Furthermore, when the clamping component is provided with a fastening part that is fastened to the base member, the fastening part can be made closer to the boundary of the interior component's appearance.

[0019] In addition, the clamping component has a first wall portion, a second wall portion, and a third wall portion. A gap is formed between the front end of the third wall portion and the front end of the protrusion that protrudes from the back of the substrate. When the folded portion is inserted into the clamping component through the gap and clamped between the second wall portion and the back of the substrate, the folded portion can be clamped simply and firmly.

[0020] Furthermore, when multiple clamping components are provided along at least one side of the substrate, the elongated folded portion can be clamped without wobbling. Attached Figure Description

[0037] The matters illustrated herein are illustrative and serve to illustrate embodiments of the invention. The principles and conceptual features of the invention are described for the purpose of providing what is considered the most efficient and readily understandable explanation. In this respect, it is not intended to depict the detailed construction of the invention beyond what is necessary for a fundamental understanding of the invention, but rather to make clear to those skilled in the art how several aspects of the invention are actually embodied through description in conjunction with the accompanying drawings.

[0038] For example, such as Figure 1 and Figure 2 As shown, the interior trim component 1 of this embodiment includes a plate-shaped base material 2 fastened to the base member 43 and a skin component 3 covering the surface of the base material 2. The skin component 3 has a fabric 7 with optical fibers 4 woven in as constituent lines. The skin component 3 is provided with a folded portion 11 that is folded multiple times and folded back to the back of the base material. A clamping member 15 for holding the folded portion 11 is provided on the back of the base material 2.

[0039] The shape of substrate 2 is not particularly limited. Substrate 2 can have a planar shape that is not a planar rectangular shape (and also includes a square shape). Specifically, substrate 2 is formed in a longitudinal shape and can have a planar shape in which the width of the plate in the direction orthogonal to its longitudinal direction gradually changes along the longitudinal direction (see reference). Figure 5 ).

[0040] On the back of the substrate 2, a fastening part 18 (specifically a fastening protrusion) that is fastened to the base member 43 can be provided (see reference). Figure 6 The fastening part 18 can be provided in multiple forms along at least one side portion 2a, 2b of the base material 2. Furthermore, the fastening method between the fastening part 18 and the base member 43 is not particularly limited; one or more combinations of threaded fastening, fitting fastening, stop fastening, adhesive fastening, etc., can be appropriately selected. Specifically, the fastening part 18 and the mounting part 19 provided on the base member 43 can be fastened using screws. In addition, the fastening part 18 is required to be located near the boundaries D1, D2 on the appearance of the interior trim component 1 (i.e., the mating portions of the interior trim component 1 and other interior trim components 44, 45; the portions of the interior trim component 1 where pressing pressure from other interior trim components 44, 45 is applied).

[0041] The material of substrate 2 is not particularly limited. Substrate 2 can contain thermoplastic resin. Examples of thermoplastic resins include polyolefins (especially polypropylene), polyesters, polystyrene, acrylic resins, polyamides, polycarbonates, polyacetals, and ABS. Only one type of resin may be used, or two or more may be used in combination. Furthermore, the substrate can contain the aforementioned thermoplastic resin and reinforcing fibers. Reinforcing fibers can 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 polyesters, polyamides, and aromatic polyamides). Only one type of fiber may be used, or two or more may be used in combination. Additionally, plant fibers include bast fibers (e.g., hibiscus, flax, jute, hemp, ramie, etc.), vein fibers (e.g., banana, shisha, agave, etc.), woody fibers (e.g., plant fibers obtained from broadleaf and coniferous trees), and other plant fibers (coconut husk fiber, oil palm hollow fruit fiber, rice straw fiber, wheat straw fiber, bamboo fiber, cotton, etc.). These fibers can be used in single-origin or in combination of two or more. Furthermore, there are no particular limitations on the material of the base component. The base component can be made of the same material as the aforementioned substrate.

[0042] The skin component 3 covers all or part of the surface of the substrate 2. The skin component 3 may be adhered to the surface of the substrate 2 using an adhesive or the like, or it may not be adhered to the surface of the substrate 2. Furthermore, the skin component 3 has a fabric 7 with optical fibers 4 woven into it as constituent threads. Additionally, the skin component 3 may have the fabric 7 and a buffer layer 8 laminated on the back of the fabric 7 (see reference). Figure 4 The material of the cushioning layer 8 is not particularly limited, but it is mostly made of sheet material composed of soft polyurethane foam. In addition, other soft resin foams can also be used as long as they have sufficient cushioning.

[0043] The outer skin 3 can have a planar rectangular shape (including square shapes) to prevent the optical fiber 4 from being cut (see reference). Figure 5 When the planar rectangular skin 3 covers the surface of the non-planar rectangular substrate 2, the remaining portions 3a and 3b of the skin 3 are generated along at least one side 2a and 2c of the substrate 2. The remaining portions 3a and 3b of the skin 3 are generally formed in a longitudinal shape along one side 2a and 2b of the substrate 2, and their size gradually changes along the longitudinal direction in the direction orthogonal to the longitudinal direction.

[0044] Fabric 7 is a cloth woven from constituent threads (warp and weft), and its weave structure is not particularly limited. Specifically, various weave structures such as plain weave, twill weave, and satin weave can be used. At least one optical fiber 4 (see reference) is used among the constituent threads of fabric 7. Figure 4As for the optical fiber 4, various types of optical fibers 4 can be adopted, including those with a core (core layer) and a sheath (cladding) structure (multilayer structure), and the core layer and cladding have different refractive indices. The optical fiber 4 can be a side-emitting type where light incident from one end is emitted partially or entirely from the circumferential surface, or an end-emitting type where light incident from one end is emitted from the other end. In particular, when using a side-emitting type optical fiber 4, light from the light source 6 can be emitted from the surface of the fabric 7 (i.e., the skin 3) in which the optical fiber 4 is woven, thus further improving the appearance and performance effect.

[0045] The optical fiber 4 is used in at least one of the warp and weft threads constituting the fabric, and in particular, it can be configured to be used in the weft thread. When the optical fiber 4 is used as a warp thread, with the total number of warp threads set to 100%, the proportion of optical fiber 4 used as a 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. Similarly, when the optical fiber 4 is used as a weft thread, with the total number of weft threads set to 100%, the proportion of optical fiber used as a 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. Furthermore, the diameter of the optical fiber 4 is not particularly limited, but from the viewpoint of weavability and versatility, it is preferably 0.25 mm to 3 mm, more preferably 0.1 mm to 1 mm.

[0046] The types of constituent threads (hereinafter referred to as "other constituent threads") constituting fabric 7, excluding optical fiber 4, are not particularly limited, but constituent threads made of plant-based and animal-based natural fibers, regenerated fibers such as rayon, semi-synthetic fibers such as cellulose acetate, and synthetic fibers made of synthetic resins can be used. Examples of resins constituting synthetic fibers include, for example, polyamide resins such as nylon 6 and nylon 66, polyester resins such as polyethylene terephthalate, polybutylene terephthalate, and polypropylene terephthalate, polyolefin resins such as high-density polyethylene and polypropylene, and polyacrylic acid resins.

[0047] Among the other constituent threads constituting the fabric 7, the warp and weft threads may be the same or different threads. Furthermore, the other constituent threads used for the warp may be of only one type or may be two or more types used together. Similarly, the other constituent threads used for the weft may be of only one type or may be two or more types used together. Additionally, the fineness of the other constituent threads 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.

[0048] The outer skin 3 is provided with a folded portion 11 that is folded into multiple sheets and folded back to the back of the substrate 2 (see reference). Figure 8 The folded portion 11 can be formed by folding the remaining portion 3a of the skin member 3 into multiple sheets and then folding it back towards the back of the substrate 2, or by folding the remaining portion 3a of the skin member 3 back to the back of the substrate 2 and then folding it into multiple sheets. In addition, the folded portion 11 can be folded in such a way that the backs (i.e., non-exterior surfaces) of the remaining portion 3a of the skin member 3 are in contact with each other, or it can be folded in such a way that the surfaces (i.e., exterior surfaces) of the remaining portion 3a of the skin member 3 are in contact with each other. When it is folded into three or more sheets, it can also be a combination of the above forms.

[0049] The folded portion 11 can be formed longitudinally along one side 2a of the substrate 2. This folded portion 11 can be folded with a number of folds and / or a fold width (i.e., the width in a direction orthogonal to the longitudinal direction of the folded portion 11) corresponding to the size of the remaining portion 3a of the skin piece 3. Specifically, the folded portion 11 can have a portion folded with a first number of folds and a portion folded with a second number of folds (more than the first number of folds) along its longitudinal direction. Furthermore, the folded portion 11 can have a portion folded with a first fold width and a portion folded with a second fold width greater than the first fold width along its longitudinal direction.

[0050] The clamping component 15 can also be mounted separately from the substrate 2 and attached to the back of the substrate 2, but from the viewpoint of reducing the number of components, it is preferable to integrally form it with the substrate 2 (specifically, integrally form it). The number of clamping components 15 is not particularly limited, but in order to clamp the elongated folded portion 11, it is preferable to have a plurality of them along at least one side 2a of the substrate 2 (see reference). Figure 6 The spacing P1 and P2 between adjacent clamping components among the multiple clamping components 15A to 15C can be set to values ​​that prevent the elongated folded portion 11 held by each clamping component from wobbling (see reference). Figure 5 Furthermore, the number of folds and / or the fold width can differ between portions of the folded portion 11 held by one adjacent clamping member among the multiple clamping members 15A to 15C and portions of the folded portion 11 held by another clamping member (see reference). Figure 8 Furthermore, when inserting the folding part 11 into multiple clamping components 15A to 15C, the folding part 11 can be inserted into each clamping component 15A to 15C sequentially, or the folding part 11 can be inserted into at least two or more clamping components simultaneously.

[0051] For example, such as Figure 7 and Figure 8As shown, the clamping member 15 includes: a first wall portion 21, which stands upright on the back surface of the substrate 2; a second wall portion 22, which extends from the upright end of the first wall portion 21 toward the outer edge (i.e., end) of the substrate 2; and a third wall portion 23, which extends from the end side (i.e., the front end) of the second wall portion 22 near the outer edge of the substrate 2 toward the back surface of the substrate 2, and a gap C is formed between the front end of the third wall portion 23 and the front end of the protrusion 24 protruding from the back surface of the substrate 2. Furthermore, the folding portion 11 can be inserted into the clamping member 15 via the gap C (specifically, the space S enclosed 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 substrate 2), and is clamped between the second wall portion 22 and the back surface of the substrate 2. Additionally, the third wall portion 23 can be configured such that its front end faces the inner portion of the protrusion 24 on the back surface of the substrate 2 (see reference). Figure 11 (b)), but from the viewpoint of the clamping ability of the folded portion 11, the third wall portion 23 is preferably arranged such that its front end is opposite to the front end of the protrusion 24 (see reference). Figure 3 ).

[0052] The gap C only needs to form the insertion port of the folded portion 11, and its size is not particularly limited. The interval C1 of the gap C can be set such that the folded portion 11 can be inserted into the clamping member 15 in a flattened state in the thickness direction, and the value of the folded portion 11 inserted into the clamping member 15 (i.e., the folded portion 11 that has expanded from the flattened state) can be restricted from falling out. Moreover, the interval C1 of the gap C can be set to a value smaller than the thickness of the non-folded portion 12 of the skin member 3 connected to the folded portion 11 (i.e., the portion that has not been folded into multiple sheets and has been folded back to the back of the substrate 2). In this case, when the folded portion 11 is inserted into the clamping member 15, the non-folded portion 12 can be clamped between the front end of the third wall portion 23 and the front end of the protrusion 24. Moreover, the longitudinal width L of the space S can be set to a value that is approximately the same as the folded width of the folded portion 11 inserted into the clamping member 15. Moreover, 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 clamping member 15.

[0053] To improve the strength of the clamping component 15, the first wall portion 21 and the second wall portion 22 are preferably connected by a connecting wall 26 with an arc-shaped cross-section. Furthermore, the second wall portion 22 and the third wall portion 23 are preferably connected by a connecting wall 27 with an arc-shaped cross-section. Additionally, the outer surface of the first wall portion 21 (i.e., the surface facing the side opposite to space S) and the back surface of the substrate 2 are preferably connected by reinforcing ribs 28. These reinforcing ribs 28 can be respectively disposed at both ends of the first wall portion 21 in the transverse direction (i.e., along the direction of one side portion 2a of the substrate 2). Moreover, the inner surfaces of the second wall portion 22 (i.e., the surface forming space S) and the third wall portion 23 (i.e., the surface forming space S) are preferably connected by reinforcing ribs 29. These reinforcing ribs 29 can be disposed at the middle portions of the second wall portion 22 and the third wall portion 23 in the transverse direction (i.e., along the direction of one side portion 2a of the substrate 2).

[0054] The location of the protrusion 24 is not particularly limited. The protrusion 24 can be located on the back side of the substrate 2, extending inward from the outer edge (see reference). Figure 11 (a)), but in order to make the fastening part 18 closer to the boundary D1 of the appearance of the interior part 1, it is preferably disposed on the outer edge side of the back of the base material 2 (see reference). Figure 3 In this case, the protrusion 24 can be formed by bending the outer edge of the substrate 2 toward the back side.

[0055] The protrusion 24 can extend linearly along one side 2a of the substrate 2. The length of this linear extension of the 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 greater than or equal to the lateral width (i.e., the width along the direction of one side 2a of the substrate 2) of the third wall portion 23 of the clamping member 15. In particular, from the viewpoint of the strength of the substrate 2, the protrusion 24 preferably has a length approximately the same as that of one side 2a of the substrate 2 (see reference). Figure 6 ).

[0056] The clamping component 15 can be provided with the aforementioned fastening part 18 that is fastened to the base member 43 (see reference). Figure 3 and Figure 7 The fastening part 18 can be disposed in the root 34 of the clamping member 15 that stands upright on the back of the substrate 2 (specifically, the portion extending over the first wall portion 21 and the second wall portion 22) (see reference). Figure 3 and Figure 7To improve the strength of the clamping component 15 and the fastening part 18, the outer surface of the fastening part 18 and the back surface of the substrate 2 are preferably connected by a reinforcing rib 35. The end of the reinforcing rib 35 can abut against the surface of the base member 43 when the fastening part 18 is fastened to the base member 43. Furthermore, the outer surface of the fastening part 18, the outer surface of the clamping component 15 (specifically the outer surface of the first wall portion 21), and the back surface of the substrate 2 are preferably connected by a reinforcing rib 36. The end of the reinforcing rib 36 can abut against the surface of the base member 43 when the fastening part 18 is fastened to the base member 43. In addition, the clamping component 15, the fastening part 18, and the reinforcing ribs 35 and 36 can be integrally formed with respect to the substrate 2 (specifically, integrally formed).

[0057] The fastening part 18 can be disposed in the clamping member 15 at a portion closer to the outer edge of the substrate 2 than the root 34 erected on the back of the substrate 2 (specifically, the middle portion in the longitudinal width direction of the second wall portion 22 orthogonal to one side portion 2a of the substrate 2) (see reference). Figure 9 and Figure 10 To enhance the strength of the clamping component 15 and the fastening portion 18, the outer surface of the fastening portion 18, the outer surface of the clamping component 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 substrate 2 are preferably connected by reinforcing ribs 38. The ends of these reinforcing ribs 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 surfaces of the fastening portion 18 and the clamping component 15 (specifically, the outer surface of the second wall portion 22) are preferably connected by reinforcing ribs 39. The ends of these reinforcing ribs 39 can abut against the surface of the base member 43 when the fastening portion 18 is fastened to the base member 43. Additionally, the clamping component 15, the fastening portion 18, and the reinforcing ribs 38 and 39 can be integrally formed relative to the substrate 2 (specifically, integrally formed).

[0058] The application of this interior component is not particularly limited. Examples of such interior components include door trim panels, dashboards, roof trim, floor trim, luggage compartment trim, rear side trim, rear shell, rear window sill, pillar trim, switch bases, rear side panel outer panels, armrests, center console, overhead console, sun visors, and seats. Furthermore, it can also be an interior component that constitutes furniture such as sofas or chairs. Additionally, the surface (i.e., the exterior surface) at the end of this interior component 1 can abut against the end of other interior components 44 (see reference 44). Figure 3 The abutting part forms the boundary D1 on the appearance of the interior component 1.

[0059] Example

[0060] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Furthermore, in this embodiment, a decorative element constituting a vehicle door interior panel is illustrated as an example of an "interior component" of the present invention.

[0061] like Figure 1 and Figure 2 As shown, the vehicle door interior panel 41 has a base member 43 and a plate-shaped interior body 42 covered with a metal inner panel (not shown) from the inside of the passenger compartment. The interior body 42 has a decorative element 1 forming the exterior surface of the passenger compartment, an upper panel 44, and a lower panel 45.

[0062] The decorative element 1 of this embodiment includes: a plate-shaped base material 2, which is fastened to a base member 43; and a skin member 3, which covers the surface of the base material 2. The decorative element 1 is disposed between an upper plate 44 and a lower plate 45 in a vertical direction. Furthermore, the upper end surface (i.e., the appearance surface) of the decorative element 1 abuts against the lower end of the upper plate 44, forming an appearance boundary D1 of the decorative element 1 at this abutment. Similarly, the lower end surface (i.e., the appearance surface) of the decorative element 1 abuts against the upper end of the lower plate 45, forming an appearance boundary D2 of the decorative element 1 at this abutment. Additionally, the base member 43 is disposed opposite to the back surface of the decorative element 1.

[0063] The substrate 2 is formed longitudinally along the vehicle's front-rear direction A, and has a planar shape in which the width of the plate in the vertical direction gradually decreases towards the front of the vehicle (see reference). Figure 5 On the back of the substrate 2, a fastening part 18 (specifically a fastening protrusion) is provided for fastening to the base member 43 (see reference). Figure 6 Multiple fastening portions 18 are provided along the upper edge 2a and lower edge 2b of the base material 2. Furthermore, the fastening portions 18 and the mounting portion 19 provided on the base member 43 are fastened together using screws (see reference). Figure 7 Additionally, a protrusion 24 is provided on the back side of the substrate 2, extending linearly along the upper edge 2a. This protrusion 24 has approximately the same length as the upper edge 2a.

[0064] The outer skin component 3 comprises: fabric 7, in which side-emitting optical fibers 4 are woven as constituent threads; and a buffer layer 8, which is layered on the back of the fabric 7 (see reference). Figure 4 By using the optical fiber 4 to direct light from the light source 6 through the surface of the fabric 7 (i.e., the outer skin 3), the appearance and performance effect can be further improved. Furthermore, bundled portions 5 of the optical fiber 4 are provided at both ends of the outer skin 3 in a predetermined direction (specifically, the vehicle's front-to-back direction A), and light from the light source 6 is incident on each bundled portion 5 (see reference 4). Figure 5 The light source 6 is held by a holding part (not shown) located on the back side of the substrate 2.

[0065] The outer skin 3 has a planar rectangular shape to prevent the optical fiber 4 from being cut (see reference). Figure 5 When the planar rectangular skin 3 covers the surface of the non-planar rectangular substrate 2, the remaining portions 3a and 3b of the skin 3 are formed along the upper edge 2a and side edge 2c of the substrate 2. The remaining portions 3a and 3b of the skin 3 are formed in a longitudinal shape along the upper edge 2a and side edge 2c of the substrate 2, and their size gradually changes along the longitudinal direction in a direction orthogonal to the longitudinal direction.

[0066] The outer skin 3 is provided with a folded portion 11 that is folded into multiple sheets and folded back to the back of the substrate 2 (see reference). Figure 8 The folded portion 11 is formed into a longitudinal shape along the upper edge 2a of the substrate 2 by folding the remaining portion 3a of the skin piece 3. Furthermore, the remaining portion 3b of the skin piece 3 along the side edge 2c of the substrate 2 is not folded but folded back to the back of the substrate 2 and glued to the back of the substrate 2 using an adhesive or the like.

[0067] A clamping component 15 for holding the folded portion 11 is provided on the back side of the substrate 2 (see reference). Figure 6 The clamping component 15 is provided with multiple ( ) along the upper edge 2a of the substrate 2. Figure 6 (3 in total) to clamp the elongated folded portion 11. The spacing between adjacent clamping components 15 is set such that the elongated folded portion 11 clamped by each clamping component 15 does not wobble. More specifically, the spacing P1 between clamping components 15A and 15B is set to approximately 140 mm, the spacing P2 between clamping components 15B and 15C is set to approximately 150 mm, and the spacing P3 between clamping component 15C and the side of the substrate 2 is set to approximately 100 mm (see reference). Figure 5 ).

[0068] like Figure 7 and Figure 8 As shown, clamping components 15A-15C include a first wall portion 21, a second wall portion 22, and a third wall portion 23. The first wall portion 21 stands upright on the back surface of the substrate 2. The second wall portion 22 extends from the upright end of the first wall portion 21 toward the outer edge of the substrate 2. The third wall portion 23 extends from the end of the second wall portion 22 near the outer edge of the substrate 2 toward the back surface of the substrate 2 (specifically, the protrusion 24). A gap C is formed between the front end of the third wall portion 23 and the front end of the protrusion 24, forming an insertion port for the folding portion 11. The folding portion 11 is inserted into the clamping components 15A-15C via the gap C (specifically, the space S enclosed 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 substrate 2), and is clamped between the second wall portion 22 and the back surface of the substrate 2.

[0069] The first wall portion 21 and the second wall portion 22 are connected by a connecting wall 26 with an arc-shaped cross-section. Furthermore, the second wall portion 22 and the third wall portion 23 are connected by a connecting wall 27 with an arc-shaped cross-section. Additionally, the outer surface of the first wall portion 21 and the back surface of the substrate 2 are connected by reinforcing ribs 28. These reinforcing ribs 28 are respectively disposed at both ends of the first wall portion 21 in the transverse direction. Moreover, the inner surfaces of the second wall portion 22 and the third wall portion 23 are connected by reinforcing ribs 29. These reinforcing ribs 29 are disposed in the middle portion of the second wall portion 22 in the transverse direction.

[0070] like Figure 3 and Figure 7 As shown, the clamping member 15A is provided with the aforementioned fastening portion 18 (specifically, a fastening protrusion) that is fastened to the base member 43. This fastening portion 18 and the mounting portion 19 provided on the base member 43 are fastened together using screws 33. Furthermore, the fastening portion 18 is disposed in the root portion 34 of the clamping member 15A that stands upright on the back side of the substrate 2 (specifically, covering portions of the first wall portion 21 and the second wall portion 22). Additionally, the outer peripheral surface of the fastening portion 18 and the back side of the substrate 2 are connected by reinforcing ribs 35. Moreover, the outer peripheral surface of the fastening portion 18, the outer surface of the first wall portion 21, and the back side of the substrate 2 are connected by reinforcing ribs 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.

[0071] Here, the dimensions of the gap C and space S between each clamping component 15A to 15C will be explained. Furthermore, in this embodiment, the thickness of the portion of the skin component 3 excluding the folded portion 11 is set to approximately 5.6 mm; the thickness of the portion 11 folded into two sheets is set to approximately 2 mm by flattening it in the thickness direction; and the thickness of the portion 11 folded into three sheets is set to approximately 3 mm by flattening it in the thickness direction.

[0072] like Figure 8 As shown, in clamping component 15A, in order to clamp the folded portion 11 folded into two sheets, the interval C1 of the gap C is set to approximately 3 mm, the longitudinal width L of the space S is set to approximately 15 mm, and the height H of the space S is set to approximately 10 mm. Furthermore, in clamping component 15B, in order to clamp the folded portion 11 folded into two sheets, the interval C1 of the gap C is set to approximately 3 mm, the longitudinal width L of the space S is set to approximately 20 mm, and the height H of the space S is set to approximately 10 mm. Moreover, in clamping component 15C, in order to clamp the folded portion 11 folded into three sheets, the interval C1 of the gap C is set to approximately 5 mm, the longitudinal width L of the space S is set to approximately 20 mm, and the height H of the space S is set to approximately 15 mm.

[0073] Next, the effect of the decorative element 1 with the above structure will be explained. When the folded portion 11, which is flattened along the thickness direction, is inserted into the clamping member 15 through the gap C, the second wall portion 22 deforms away from the back side of the substrate 2 (i.e., the direction in which the gap C widens) using the folded portion 11 as a fulcrum, and the folded portion 11 passes through the gap C. Then, when the folded portion 11 is fully inserted into the clamping member 15, the folded portion 11 expands from the flattened state and is clamped between the second wall portion 22 and the back side of the substrate 2, and between the reinforcing rib 29 and the back side of the substrate 2. Moreover, the non-folded portion 12 connected to the folded portion 11 is clamped between the front end of the third wall portion 23 and the front end of the protrusion 24. In this clamped state, the folded portion 11 is prevented from dislodging from the clamping member 15 by the third wall portion 23 and the protrusion 24.

[0074] As described above, according to the decorative item 1 of this embodiment, the outer skin 3 has a fabric 7 with optical fibers 4 woven into it as constituent threads. The outer skin 3 has folded portions 11 that are folded into multiple sheets and folded back to the back of the substrate 2. Clamping members 15A to 15C that hold the folded portions 11 are provided on the back of the substrate 2. This reduces the folding area of ​​the remaining portion 3a of the outer skin 3 folding back to the back of the substrate 2. Therefore, the fastening portion 18 relative to the base member 43 can be positioned on the back of the substrate 2 near the outer edge, making it close to the visual boundaries D1 and D2 of the decorative item 1.

[0075] Furthermore, in this embodiment, a fastening portion 18 is provided on the clamping member 15A for fastening to the base member 43. As a result, the fastening portion 18 can be made closer to the boundary D1 on the appearance of the decoration 1.

[0076] Furthermore, in this embodiment, the fastening part 18 is disposed at the root 34 of the clamping member 15A, which stands upright on the back side of the substrate 2. Thus, even if the substrate 2 is made of polypropylene or the clamping member 15A, which is integrally formed with the substrate 2, is prone to bending, the fastening part 18 can be properly fastened to the base member 43.

[0077] In this embodiment, the clamping components 15A-15C include a first wall portion 21, a second wall portion 22, and a third wall portion 23. A gap C is formed between the front end of the third wall portion 23 and the front end of the protrusion 24 protruding from the back surface of the substrate 2. The folded portion 11 is inserted into the clamping components 15A-15C through the gap C and is clamped between the second wall portion 22 and the back surface of the substrate 2. Thus, the folded portion 11 can be clamped simply and securely.

[0078] Furthermore, 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 reinforcing ribs 29. Therefore, the folded portion 11 can be more securely clamped by pressing with the reinforcing ribs 29.

[0079] Furthermore, in this embodiment, multiple clamping components 15A to 15C are provided along the upper edge 2a of the substrate 2. As a result, the elongated folded portion 11 can be clamped without causing wobbling.

[0080] Next, the decorative element of the modified example will be described, but the parts with the same structure as the decorative element 1 described above will be marked with the same reference numerals and the description will be omitted.

[0081] like Figure 9 and Figure 10 As shown, a fastening portion 18 (i.e., a fastening protrusion) is provided on the clamping member 15A for fastening to the base member 43. This fastening portion 18 and the mounting portion 19 provided on the base member 43 are fastened together by screws 33. In addition, the fastening portion 18 is located in the clamping member 15A at a portion closer to the outer edge of the base material 2 than the root portion 34 that stands on the back side of the base material 2 (specifically, the middle portion in the longitudinal width direction of the second wall portion 22).

[0082] The outer peripheral surface of the fastening part 18, the outer surface of the clamping member 15A (specifically, the outer surface of the second wall part 22 and the outer surface of the first wall part 21), and the back surface of the base material 2 are connected by reinforcing ribs 38. Furthermore, the outer peripheral surface of the fastening part 18 and the outer surface of the clamping member 15A (specifically, the outer surface of the second wall part 22) are connected by reinforcing ribs 39. The ends of these reinforcing ribs 38 and 39 abut against the surface of the base member 43 when the fastening part 18 is fastened to the base member 43.

[0083] According to this clamping component 15A, when the material of the base material 2 is ABS resin or the clamping component 15A integrally formed with the base material 2 is not easily bent, the fastening part 18 relative to the base member 43 can be made closer to the boundary D1 on the appearance of the decoration 1.

[0084] Furthermore, this invention is not limited to the embodiments described above, and various modifications can be made within the scope of this invention depending on the purpose and application. That is, in the above embodiments, a clamping member 15 is illustrated, comprising a first wall portion 21, a second wall portion 22, and a third wall portion 23, with a gap C formed between the front end of the third wall portion 23 and the front end of the protrusion 24; however, it is not limited to this, for example, such as... Figure 11 As shown in (c), it can also be configured as a clamping member 15 that does not have a third wall portion 23, but has a first wall portion 21 and a second wall portion 22, and forms a gap C between the front end of the second wall portion 22 and the front end of the protrusion 24.

[0085] Furthermore, in the above embodiment, a fastening portion 18 is provided on one of the clamping components 15A to 15C, but this is not a limitation. For example, the fastening portion 18 may be provided on at least two or more of the clamping components 15A to 15C. Additionally, an abutment portion that abuts against the base member 43 may be provided on the clamping component 15A. Moreover, it is also possible to omit the fastening portion 18 and the abutment portion from the clamping components 15A to 15C.

[0086] The examples above are for illustrative purposes only and are not intended to limit the invention. Examples of typical embodiments are given to illustrate the invention; however, it is understood that the language used in the description and drawings is not limiting but illustrative and exemplary. As detailed herein, modifications can be made within the scope and spirit of the appended claims without departing from the scope and spirit of the invention. Specific structures, materials, and embodiments are referenced in the detailed description of the invention, but it is not intended to limit the invention to the matters disclosed herein; rather, the invention relates to all functionally equivalent structures, methods, and uses within the scope of the appended claims.
