Description

[Technical Field]

[0001] The present invention relates to a skin-decorated component including a base material and a skin body for decoration. [Background technology]

[0002] Conventionally, decorative skin parts used, for example, as interior materials for automobiles, have been known in which the surface of a synthetic resin substrate is covered with a skin body made of leather or the like. The substrate has vertical walls extending from the outer edge of the substrate main body to the back side, and the skin body covers the surface of the substrate from the substrate main body to the vertical walls, with the end portions folded back from the tips of the vertical walls to the back side and fixed to the substrate. In the case of rectangular substrates, excess material is generated at the end portions of the skin body at the corners of the vertical walls, so the thickness of the vertical walls is increased at the corners to accommodate this excess material (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 7-81487 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-described configuration, the thickness of the vertical wall portion is not uniform between the vicinity of the corner portion and other portions, and therefore there is a concern that the appearance of the design portion of the skin body covering the vertical wall portion may be affected by the uneven thickness.

[0005] The present invention has been made in consideration of the above points, and has as its object to provide a skin-decorated part that can suppress poor appearance caused by excess wrinkles at the end portion of the skin body. [Means for solving the problem]

[0006] An epidermal-decorated part according to one aspect of the present invention is an epidermal-decorated part comprising a base material and a skin body for decoration, wherein the base material has a base material main body portion, a peripheral wall portion erected on the back side of the base material main body portion and positioned along the outer edge of the base material main body portion, and an extended wall portion erected on the back side of the base material main body portion and positioned along a direction inclined inwardly of the base material main body portion with respect to the outer edge of the base material main body portion, and the skin body has a skin body main body portion covering at least a part of the front side of the base material main body portion, a first terminal portion covering the front side of the peripheral wall from the outer edge of the base material main body portion, and a second terminal portion covering the front side of the extended wall from the back side of the base material main body portion and continuing to the first terminal portion. [Effects of the Invention]

[0007] According to the present invention, excess wrinkles at the end portion of the skin body are concentrated at the second end portion, making it difficult for excess wrinkles to occur at the first end portion, and thereby suppressing poor appearance caused by these excess wrinkles. [Brief explanation of the drawings]

[Figure 2] FIG. 2 is a plan view showing a part of the base material from the opposite design side. DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0010] In FIG. 1(a), 1 denotes a skin-decorating part. The skin-decorating part 1 may be any type, but in this embodiment, it is, for example, an interior material for a vehicle such as an automobile. The skin-decorating part 1 includes a base material 2 and a skin body 3 for decorating the base material 2. A separate member such as an elastic material (cushioning material) may be disposed at least partially between the base material 2 and the skin body 3. The shape of the skin-decorating part 1 may be set to any shape, such as a square or a circle.

[0011] 1(a) and 1(b) is molded from a hard material such as synthetic resin. In this embodiment, the base material 2 has a base material main body 5 that occupies the majority of the base material 2 and a vertical wall portion 6 that is integrally provided upright on the base material main body 5.

[0012] The substrate body 5 is the main design component of the skin-decorating component 1 in use. In this embodiment, the substrate body 5 is formed, for example, in a plate shape. The substrate body 5 has a front side, which is one main surface at least partially covered by the skin body 3, and a back side, which is the other main surface not covered by the skin body 3. In the figure, the arrow D1 indicates the front side of the substrate body 5, and the arrow D2 indicates the back side of the substrate body 5. The front side of the substrate body 5 is essentially flat or has minimal irregularities. The back side of the substrate body 5 may have structural components such as reinforcing ribs or mounting portions 12 for mounting the skin-decorating component 1 to a mounting target, at positions other than the vertical wall portions 6, for example, at positions away from the outer edge 10 of the substrate body 5. For example, the mounting portion 12 is located away from the rear of the vertical wall portions 6.

[0013] The vertical wall portion 6 is erected on the back side of the substrate body portion 5. The vertical wall portion 6 is close to the outer edge portion 10 of the substrate body portion 5.

[0014] The vertical wall portion 6 has a peripheral wall portion 14. The peripheral wall portion 14 is a portion that is continuous with the substrate body portion 5 and forms a surface that extends in a direction different from the front side of the substrate body portion 5, and defines the design area A1 of the skin body 3. The peripheral wall portion 14 is located along the outer edge portion 10 of the substrate body portion 5. Here, "located along the outer edge portion 10" does not only mean being flush or approximately flush with the outer shell line of the outer edge portion 10, but also includes a configuration in which the peripheral wall portion 14 extends along the outer shell line of the outer edge portion 10 and near the outer shell line of the outer edge portion 10 while maintaining a constant or approximately constant distance from the outer shell line of the outer edge portion 10. In this embodiment, the peripheral wall portion 14 is located slightly offset inward of the substrate body portion 5 with respect to the outer shell line of the outer edge portion 10. The peripheral wall portion 14 extends along at least a portion of the outer edge portion 10 of the substrate body portion 5. The peripheral wall 14 has a thickness in the inward and outward directions of the substrate body 5, and this thickness is set to be constant or approximately constant. The side of the peripheral wall 14, indicated by arrow D3, pointing outward from the substrate 2, is the front side, and the side of arrow D4, pointing inward from the substrate 2, is the back side. The tip of the peripheral wall 14, i.e., the end 15 away from the substrate body 5, defines the terminal end of the design portion of the skin-decorating component 1. In this embodiment, the peripheral wall 14 and the end 15 are parallel or approximately parallel to the outer edge 10 of the substrate body 5. While "parallel" is typically defined as a linear relationship, in this embodiment it means that the distance between them is constant or approximately constant, and is not intended to limit their shapes to linear shapes. The peripheral wall 14 may have recesses or holes formed in the thickness direction at any position except the end 15.

[0015] The vertical wall portion 6 also has an extended wall portion 17. The extended wall portion 17 is a portion that is continuous with the base body portion 5 and is adjacent to or continuous with the peripheral wall portion 14, forming a surface that extends in a direction different from the front side of the base body portion 5 and the front side of the peripheral wall portion 14, and that defines the non-design area A2 of the skin body 3. For clarity, the non-design area A2 is shown as a shaded portion in FIG. 1( a). The extended wall portion 17 is positioned along a direction that slopes inward of the base body portion 5 with respect to the outer edge portion 10 of the base body portion 5. In other words, the extended wall portion 17 extends in a direction different from the direction along the outer edge portion 10 of the base body portion 5. In the illustrated example, the extended wall portion 17 extends in a direction that intersects the extension direction of the peripheral wall portion 14, for example, in a direction that is perpendicular or substantially perpendicular.

[0016] In this embodiment, the extended wall portion 17 is continuous with the end of the peripheral wall portion 14. Therefore, at the position where the extended wall portion 17 and the peripheral wall portion 14 are continuous, the vertical wall portion 6 forms an L-shaped bent corner portion. The extended wall portion 17 has a thickness in the inner and outer directions of the base material main body portion 5, and this thickness is set to be constant or approximately constant. In the extended wall portion 17, the side indicated by the arrow D5 pointing outward from the base material 2 is the front side, and the side indicated by the arrow D6 pointing inward from the base material 2 is the back side.

[0017] The tip of the extension wall 17, i.e., the end 18 remote from the base body 5, is formed to be continuous with the end 15 of the peripheral wall 14. In this embodiment, these ends 18 and 15 are located on the same plane or approximately on the same plane, and in the illustrated example, are continuous to form a smooth continuous surface.

[0018] Furthermore, the outer edge 10 of the substrate main body 5 is bent or curved at a position close to the extended wall 17 and a position close to the peripheral wall 14. That is, the outer edge 10 of the substrate main body 5 has a first outer edge 10a close to the peripheral wall 14 and a second outer edge 10b close to the extended wall 17 that is inclined. In other words, the position where the first outer edge 10a and the second outer edge 10b join forms a corner of the outer edge 10 of the substrate main body 5. In the example shown, the second outer edge 10b is inclined in a direction that forms an obtuse angle with the first outer edge 10a.

[0019] In this embodiment, a surface portion 20 is formed on the back side of the substrate main body 5, between the second outer edge portion 10b and the extended wall portion 17. That is, the surface portion 20 is located close to the extended wall portion 17. The surface portion 20 is a shelf surface that forms part of the back surface of the substrate main body 5 and defines the non-design area A2 of the skin 3. In this embodiment, the surface portion 20 is planar. In the illustrated example, the surface portion 20 is triangular, with two sides along the second outer edge portion 10b and the extended wall portion 17 of the substrate main body 5, and one side extending from the vicinity of the end of the extended wall portion 17 to the second outer edge portion 10b. As shown in FIG. 2 , the end face of the outer edge portion 10 of the substrate main body 5, i.e., the end face of the second outer edge portion 10b, and the surface of the extended wall portion 17 intersect at a predetermined angle θ. This predetermined angle θ is defined as the angle, as viewed from the front to back direction of the substrate body 5, between, for example, a tangent to a fillet terminal portion of the end side of the extended wall portion 17 that is continuous with the peripheral wall portion 14, and a tangent to a fillet terminal portion of the second outer edge portion 10b at a corner portion of the outer edge portion 10. The predetermined angle θ may be set to any acute angle, but is preferably set to an acute angle of 25° or more.

[0020] 1(a), the skin body 3 is formed as an integrated sheet from one or more sheets of any material, such as natural leather, artificial leather, resin, or a composite material that is a combination of any of these. The skin body 3, in a pulled state, i.e., under tension, covers the front side of the base material 2, that is, from the front side of the base material main body 5 to the front side of the vertical wall 6, i.e., the front side of the peripheral wall 14 and the front side of the extension wall 17, as shown in FIG. 1(b), and is bonded and fixed to the base material 2 by adhesive, welding, or the like.

[0021] As shown in Fig. 1(a), the skin body 3 includes a skin body main body portion 22. The skin body main body portion 22 is a portion that forms the main part of the skin body 3, and is a design portion (main design portion) that covers at least a portion of the front side of the substrate main body portion 5 (shown in Fig. 1(b)) of the substrate 2, forms part of the design area A1, and constitutes the main part of the design of the skin decorative part 1 when in use. Preferably, the skin body main body portion 22 is bonded and fixed to at least a portion of the front side of the substrate main body portion 5 (shown in Fig. 1(b)).

[0022] The skin body 3 has a terminal portion 23 that is continuous with the outer edge of the skin body main body 22, and is bent from the outer edge 10 of the base material main body 5 to the back side of the base material main body 5. The terminal portion 23 has a first terminal portion 23a that covers the front side of the peripheral wall portion 14 (shown in FIG. 1(b)), and a second terminal portion 23b that covers the front side of the extension wall portion 17 (shown in FIG. 1(b)).

[0023] 1(b), the first terminal portion 23a is folded from the first outer edge portion 10a of the base material main body portion 5 to cover the front side of the peripheral wall portion 14, and is folded back from the end portion 15 of the peripheral wall portion 14 to the back side of the peripheral wall portion 14 and fixed by adhesive or welding to the back side of the peripheral wall portion 14 or the back side of the base material main body portion 5. The first terminal portion 23a is connected to the skin body portion 22 and forms another part of the design area A1, and is a design portion (terminal design portion) that forms part of the continuous design of the skin decorative part 1 when in use.

[0024] 1(a) is connected to the first terminal portion 23a, is bent from the second outer edge portion 10b of the substrate main body portion 5 shown in FIG. 1(b), and covers the front side of the extended wall portion 17 from the back side of the substrate main body portion 5, which in this embodiment is a surface portion 20 that forms part of the back surface of the substrate main body portion 5, and is also folded back from an end portion 18 of the extended wall portion 17 to the back side of the extended wall portion 17 and fixed by adhesive or welding to the back side of the extended wall portion 17 or the back side of the substrate main body portion 5. The second terminal portion 23b shown in FIG. 1(a) is pressed into a space 24 between the second outer edge portion 10b (shown in FIG. 1(b)) of the substrate main body portion 5 and the extended wall portion 17 (shown in FIG. 1(b)), forming part of the non-design area A2, and is a non-design portion that does not contribute to the design of the skin decorative part 1 when in use.

[0025] In this embodiment, the skin body 3 has a stitched portion 25. The stitched portion 25 is formed, for example, at the terminal portion 23. In the illustrated example, the stitched portion 25 functions as a sewn portion that fastens the multiple sheet materials 26, 27 that make up the skin body 3 to one another, but it may also be merely for decorative purposes. For example, the stitched portion 25 is positioned linearly across the first terminal portion 23a and the second terminal portion 23b at the terminal portion 23. In the illustrated example, the extending direction of the stitched portion 25 coincides or substantially coincides with the extending direction of the vertical wall portion 6 (shown in FIG. 1(b)) of the base material 2.

[0026] Next, a method for manufacturing the skin-decorated part 1 will be described.

[0027] The sheet-shaped skin body 3 is attached to the front side of the preformed substrate 2 while pulling the terminal portion 23 so as not to wrinkle. At this time, the skin body main portion 22 of the skin body 3 is aligned with the substrate main portion 5 of the substrate 2, and the terminal portion 23 is folded from the outer edge portion 10 of the substrate main portion 5 to the back side of the substrate main portion 5 and fixed to the back side of the substrate main portion 5 by adhesive or welding. Furthermore, at a position where the vertical wall portion 6 is located close to the outer edge portion 10 of the substrate main portion 5, the terminal portion 23 covers the front side of the peripheral wall portion 14 and the extended wall portion 17 of the vertical wall portion 6 and is fixed to the back side of the vertical wall portion 6 or the back side of the substrate main portion 5 by adhesive or welding.

[0028] Here, for example, when the outer edge 10 of the substrate main body 5 is bent, the folding direction of the terminal portion 23 of the skin body 3 changes on one side and the other side of the bend position, and the terminal portions 23 of the skin body 3 gather together, which inevitably results in excess at the terminal portions 23 of the skin body 3. If this excess cannot be completely processed on the back side of the substrate 2, i.e., the non-design side, the excess at the terminal portions 23 will spread to the design side, causing wrinkles (excess wrinkles) and degrading the appearance.

[0029] Therefore, in this embodiment, the substrate 2 is formed with a peripheral wall 14 located along the outer edge 10 of the substrate main body 5 on the back side of the substrate main body 5, and an extended wall 17 located along a direction inclined inward of the substrate main body 5 with respect to the outer edge of the substrate main body 5, and the first terminal portion 23a of the terminal portion 23 of the skin body 3 covers the front side of the peripheral wall 14 from the outer edge 10 of the substrate main body 5, and the second terminal portion 23b connected to this first terminal portion 23a covers the front side of the extended wall 17 from the back side of the substrate main body 5.

[0030] That is, by pushing the second terminal portion 23b of the terminal portion 23 of the skin body 3 so as to be accommodated between the back side (face portion 20) of the substrate main body 5 and the extended wall portion 17, the portion of the terminal portion 23 of the skin body 3 where excess wrinkles W occur is concentrated in the second terminal portion 23b located in the non-design area A2 on the back side of the substrate main body 5 and to the side of the peripheral wall portion 14, making it difficult for excess wrinkles to occur in the first terminal portion 23a located in the design area A1. In other words, the space 24 between the extended wall portion 17 located in the non-design area A2 and the second outer edge portion 10b of the substrate main body 5 functions as a wrinkle treatment area for the skin body 3. Therefore, poor appearance caused by excess wrinkles can be suppressed.

[0031] Furthermore, unlike the conventional configuration in which a notch is provided at the tip of the vertical wall portion 6 (end 15 of the peripheral wall portion 14) or the thickness is changed in order to suppress excess wrinkles, in this embodiment, the thickness of the peripheral wall portion 14 around which the skin body 3 is wrapped can be kept uniform, so that unevenness in the fold lines of the first terminal portion 23a of the skin body 3 due to unevenness in the thickness of the peripheral wall portion 14 at the end 15 of the peripheral wall portion 14 is less likely to occur, and the appearance can be improved with a simple configuration.

[0032] Furthermore, since the end face of the outer edge portion 10 (second outer edge portion 10b) of the substrate main body portion 5 at the surface portion 20 intersects with the surface of the extended wall portion 17 at a predetermined angle θ, the excess of the terminal portion 23 of the skin body 3 can be reliably processed at the position of the surface portion 20 on the back side of the substrate main body portion 5, and excess wrinkles W of the skin body 3 are less likely to be exposed in the design portion.

[0033] In particular, by setting the predetermined angle θ to an acute angle of 25° or more, the effect of improving the appearance can be stably achieved.

[0034] Therefore, the skin-decorating part 1 can have a good appearance, and the marketability can be improved. [Industrial Applicability]

[0035] The present invention can be suitably used as, for example, an interior material for a vehicle. [Explanation of symbols]
