Description

[Technical field]

[0001] The present invention relates to a structure for attaching a decorative item. [Background technology]

[0002] A structure for attaching a decorative fabric piece in which the outer edge of the decorative fabric piece is inserted into a recess formed on the surface to be attached of a sheet-like base material and the outer edge of the decorative fabric piece is attached by adhesive, and a non-adhesive portion is provided on the central back surface of the decorative fabric piece, has been known for some time (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2020-15996 A Summary of the Invention [Problem to be solved by the invention]

[0004] When an ornament is attached to a skin material, the ornament may be attached so as not to protrude from the surface of the skin material. However, in such a case, if the skin material is made up of multiple layers and is relatively thick, wrinkles may easily occur in the skin material near the periphery of the ornament, which may impair the appearance quality around the ornament.

[0005] Therefore, an object of the present invention is to provide an attachment structure for an ornamental device that can prevent wrinkles from occurring in the covering material near the peripheral edge of the ornamental device, even if the ornamental device is attached so that it does not protrude from the surface of the covering material. [Means for solving the problem]

[0006] In order to achieve the above object, the present invention No. 1 Aspects ofThe mounting structure for an ornamental device comprises an ornamental device having a main body portion having a design surface on the front side and a fixed portion protruding from the rear side of the main body portion, a skin material having a through hole for inserting the fixed portion therethrough and a slit portion continuing from the through hole toward an area where the peripheral edge of the main body portion is to be positioned, and a back plate having a recess having a depth greater than or equal to the thickness of the main body portion and a through hole for inserting the fixed portion therethrough, and which accommodates the main body portion together with a portion of the skin material in the recess, thereby sandwiching the portion of the skin material between the main body portion and the skin material.

[0007] No. 1 Aspects of According to the invention, the decorative tool is attached to the skin in a state where a part of the skin is sandwiched between the main body and the back plate of the decorative tool, i.e., the main body of the decorative tool is accommodated in the recess of the back plate together with a part of the skin. At this time, since the depth of the recess of the back plate is set to be deeper than the thickness of the main body, the decorative tool does not have its design surface protruding from the surface of the skin. Also, the skin is formed with a slit portion that continues from the through hole through which the fixed part is inserted to the part where the peripheral part of the main body of the decorative tool is disposed. Therefore, even if the skin is formed relatively thick, the pressure applied to the skin is alleviated by the widening of the slit portion, and the skin near the peripheral part of the decorative tool is prevented from wrinkles.

[0008] The present invention also relates to No. 2 Aspects of The structure of the ornament is as follows: No. 1 Aspects of The decorative accessory mounting structure includes a fixing member capable of fixing the fixed portion inserted into the through hole of the back plate.

[0009] No. 2 Aspects of According to this invention, the fixed portion inserted into the through hole of the back plate is fixed by the fixing member, so that the decorative item is more reliably prevented from coming off the skin material (back plate).

[0010] The present invention also relates to No. 3 Aspects of The structure of the ornament is as follows: No. 1 or No. 2 Aspects of The structure for mounting an ornamental device is such that, when viewed from the thickness direction, the main body is formed in a generally rectangular shape having arc-shaped corner portions, is made of resin and has a parting line approximately at the center in the thickness direction, and, when viewed from a direction perpendicular to the thickness direction of the main body, at least the back side of the parting line at the corner portion is formed in an arc shape.

[0011] No. 3 Aspects of According to the invention, the main body of the decorative tool is formed in a substantially rectangular shape with arc-shaped corners when viewed from the thickness direction, and at least the parting line at the corner is formed in an arc shape on the back side when viewed from a direction perpendicular to the thickness direction. Therefore, at least in the corner, the pressing force that presses the skin material present near the corner into the recess is reduced by the corner of the main body, compared to a case where the peripheral edge of the back side from the parting line and the back side intersect at a substantially right angle. This effectively prevents wrinkles from occurring in the skin material near the peripheral edge of the decorative tool when the main body of the decorative tool is accommodated in the recess of the back plate together with a part of the skin material. Note that the parting line is the most visible part of the appearance of the design surface of the decorative tool. Therefore, there is no risk of the design of the decorative tool being impaired by the shape of the back side from the parting line.

[0012] The present invention also relates to No. 4 Aspects of The structure of the ornament is as follows: No. 3 Aspects of In the decorative accessory mounting structure, a ridge portion having a curvature smaller than the curvature of the parting line at the corner portion is formed on the back surface of the main body portion at the corner portion.

[0013] No. 4 Aspects ofAccording to the invention, a ridgeline portion having a curvature smaller than that of the parting line at the corner portion is formed on the back surface of the corner portion of the main body of the decorative tool. Therefore, compared to a case where a ridgeline portion having a curvature larger than that of the parting line at the corner portion is formed on the back surface of the corner portion, the curvature of the back surface side of the corner portion is gentler, and the pressing force of the corner portion of the main body portion to push the skin material existing near the corner portion into the recess is further reduced. This more effectively prevents wrinkles from occurring in the skin material near the periphery of the decorative tool when the main body of the decorative tool is accommodated in the recess of the back plate together with a part of the skin material. In addition, the parting line is the most visible part of the appearance of the design surface of the decorative tool. Therefore, there is no risk of the design of the decorative tool being impaired by the ridgeline portion. Effect of the Invention

[0014] As described above, according to the present invention, even if the decorative item is attached so as not to protrude from the surface of the covering material, it is possible to prevent wrinkles from occurring in the covering material near the periphery of the decorative item.

[Figure 8]7 is an enlarged view of a portion of the decorative device according to the present embodiment taken along line Y of FIG. 6. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. As an example, the decorative tool 30 according to this embodiment is attached to the cover material 12 of a vehicle seat (not shown). Therefore, for convenience of explanation, the arrow UP shown appropriately in each figure indicates the upward direction of the vehicle seat, the arrow FR indicates the forward direction of the vehicle seat, and the arrow RH indicates the rightward direction of the vehicle seat. In other words, in the following explanation, when the directions of up / down, front / rear, and left / right are described without special mention, they refer to the up / down, front / rear, and left / right of the vehicle seat.

[0017] 1 to 5, the mounting structure 10 according to this embodiment includes an upholstery material 12 for a vehicle seat, a resin decorative element 30 that is attached to the upholstery material 12 by sandwiching the upholstery material 12, and a resin back plate 20. The back plate 20 is disposed on the back surface side of the upholstery material 12, and the decorative element 30 is disposed on the front surface of the upholstery material 12. As an example, the decorative element 30 is provided on the right side surface of the vehicle seat.

[0018] The decorative device 30 has a generally rectangular, flat body 32 with the longitudinal direction being the front-to-rear direction. The surface of the body 32 is a design surface 34 on which a logo, pattern, etc. are displayed, and each of the four corners 33 of the body 32 is formed in an arc shape when viewed from the thickness direction of the decorative device 30 (body 32) (see FIG. 3).

[0019] In addition, a pair of approximately cylindrical protrusions 36 serving as fixed parts are integrally formed on the flat back surface 32C (see Figures 5, 7 and 8) of the main body portion 32 of the decorative device 30, spaced apart in the longitudinal direction of the main body portion 32 and extending along the thickness direction of the main body portion 32 (see Figures 2 and 5).

[0020] On the back surface 32C of the main body 32, rearward of the longitudinal center, a positioning protrusion 38 having a generally rectangular, flat shape, with the longitudinal direction being the front-to-rear direction and the normal direction being the up-down direction, is integrally formed so as to protrude along the thickness direction of the main body 32 (see Figures 2, 4, and 5).

[0021] The positioning protrusion 38 is for positioning the decorative device 30 so that it is not placed upside down, and is provided so as to protrude toward one longitudinal side (front or rear) from the longitudinal center of the main body 32. Therefore, contrary to what is shown in the figure, it may be provided so as to protrude toward the front from the longitudinal center of the main body 32.

[0022] 5, a plurality of (e.g., five) generally conical small protrusions 37 are provided at a predetermined interval in the longitudinal direction on the approximately vertical center of the back surface 32C of the main body 32 of the decorative device 30. When the decorative device 30 (main body 32) is attached to the back plate 20 with the skin 12 sandwiched therebetween, each small protrusion 37 is adapted to bite into the surface of the skin 12 and press the skin 12 toward the back plate 20 along the thickness direction of the main body 32.

[0023] 2 to 5, the back plate 20 has a body portion 22 that is substantially rectangular and bathtub-shaped, with the front-rear direction being the longitudinal direction, and is slightly larger than the body portion 32 of the decorative device 30. That is, on the front surface side of the body portion 22, a recess 24 is formed that is deeper than the thickness of the body portion 32 of the decorative device 30, and preferably deeper than the combined thickness of the body portion 32 and the skin material 12, and that can accommodate a portion of the body portion 32 and the skin material 12.

[0024] Therefore, when the main body 32 of the decorative device 30 is housed in the recess 24 of the back plate 20 together with a part of the skin 12, the decorative surface 34 does not protrude from the peripheral edge 23 of the main body 22 (even when it protrudes to the maximum extent, it is flush with the peripheral edge 23). In other words, the decorative device 30's decorative surface 34 does not protrude from the surface of the skin 12 (see FIG. 5).

[0025] Furthermore, a pair of substantially circular through holes 26 are formed in the main body 22 (recess 24) of the back plate 20, spaced apart in the longitudinal direction of the main body 22 so as to correspond to (allow each protrusion 36 to be inserted into) each protrusion 36 of the decorative device 30. Metallic push nuts 40 serving as fixing members are fitted onto the back surface of the main body 22 so as to fit onto each protrusion 36 inserted into each through hole 26.

[0026] As shown in Figures 2 and 4, each push nut 40 has a circular plate-shaped main body 42 with a substantially circular opening 46 formed in the center, and multiple (e.g., six) slit portions 48 are formed in the main body 42 at equal intervals in the circumferential direction, extending radially from the opening 46.

[0027] In other words, a plurality of (e.g., six) substantially isosceles trapezoidal claws 44 are formed at equal intervals in the circumferential direction on the main body 42 of each push nut 40, and a substantially circular opening 46 is formed at the tip of each claw 44 (see FIG. 4). The inner diameter of the opening 46 is smaller than the outer diameter of the protrusion 36.

[0028] Therefore, when the push nut 40 is fitted onto the protrusion 36 inserted into the through hole 26 (when the protrusion 36 is inserted into the opening 46), each claw 44 elastically deforms so as to spread downstream in the insertion direction of the protrusion 36, and the outer circumferential surface of the protrusion 36 is held by the restoring force of each claw 44. As a result, even if the protrusion 36 is pulled in the direction opposite to the insertion direction, the tip (edge) of each claw 44 is relatively caught on the outer circumferential surface of the protrusion 36, so that the protrusion 36 does not come out of the opening 46 (see FIG. 5).

[0029] 2, 4, and 5, a substantially rectangular through hole 28 with the longitudinal direction being the front-to-rear direction is formed in the main body 22 (recess 24) of the back plate 20, rearward of the longitudinal center. That is, this through hole 28 is formed corresponding to the positioning protrusion 38, and is formed in a size that allows the positioning protrusion 38 to be inserted. By inserting the positioning protrusion 38 into this through hole 28, the decorative device 30 is positioned so that it is not placed upside down.

[0030] 1 and 2, the skin material 12 to which the decorative item 30 is attached is not composed of one layer but of multiple layers. To give a specific example, the skin material 12 has a three-layer structure having a base of slab urethane 12A, which is a sponge body several mm thick, a skin 12B adhered to the front side of the slab urethane 12A, and a thin cloth-like backing fabric 12C adhered to the back side of the slab urethane 12A.

[0031] 2, an area 14 (indicated by imaginary line K) for attaching the decorative device 30 is defined on the surface of the skin material 12, and a pair of substantially circular through-holes 16 are formed within this area 14, through which a pair of protrusions 36 are inserted. A pair of slits 17 are formed in the skin material 12, each continuing from each through-hole 16 toward a portion where the peripheral edge of the main body 32 of the decorative device 30 (more specifically, each corner 33) will be disposed.

[0032] Specifically, within area 14, a front upper slit portion 17Fu is continuously formed from the longitudinal front through hole 16F to the vicinity of the portion where the front upper corner portion 33Fu is located, and a small hole portion 17Fs having a smaller diameter than the through hole 16F is continuously formed at the upper end portion of the front upper slit portion 17Fu (the portion farthest from the through hole 16F).

[0033] Within area 14, a front lower slit portion 17Fd is continuously formed from the longitudinal front through hole 16F to the vicinity of the portion where the front lower corner portion 33Fd is located, and a small hole portion 17Fs having a smaller diameter than the through hole 16F is continuously formed at the lower end portion of the front lower slit portion 17Fd (the portion farthest from the through hole 16F).

[0034] Similarly, within area 14, a rear upper slit portion 17Ru is continuously formed from the longitudinal rear through hole 16R to the vicinity of the portion where the rear upper corner portion 33Ru is located, and then a small hole portion 17Rs having a smaller diameter than the through hole 16R is continuously formed at the upper end portion of the upper slit portion 17Ru (the portion farthest from the through hole 16R).

[0035] Within area 14, a rear lower slit portion 17Rd is continuously formed from the longitudinal rear through hole 16R to the vicinity of the portion where the rear lower corner portion 33Rd is located, and a small hole portion 17Rs having a smaller diameter than the through hole 16R is continuously formed at the lower end portion of the rear lower slit portion 17Rd (the portion farthest from the through hole 16R).

[0036] The small holes 17Fs and 17Rs are intended to prevent further breakage of the skin 12. A through hole 18 for inserting the positioning protrusion 38 is formed in the area 14. The through hole 18 is formed in a substantially rectangular shape with the longitudinal direction being in the front-rear direction corresponding to the positioning protrusion 38, and is formed in a size that allows the positioning protrusion 38 to be inserted therein.

[0037] 6 to 8, a parting line PL protruding in a direction perpendicular to the thickness direction is formed in approximately the center in the thickness direction of the main body 32 of the decorative device 30. The parting line PL is formed by the boundary between the core and cavity of the molding die (not shown).

[0038] 7, the peripheral portion (at least each corner portion 33) of the main body portion 32 is formed in an arc shape from the parting line PL to the back surface 32C side, and is formed in a straight line from the parting line PL to the front surface (design surface 34) side, when viewed from a direction perpendicular to the thickness direction of the main body portion 32. In other words, the portion from the parting line PL to the back surface 32C side is the arc-shaped peripheral portion 32B, and the portion from the parting line PL to the front surface (design surface 34) side is the straight (tapered) peripheral portion 32A.

[0039] 8, a ridge 35 having a smaller curvature than the curvature of the parting line PL at each corner portion 33 is formed at the boundary between the arcuate periphery 32B and the flat back surface 32C at each corner portion 33 on the back surface 32C of the main body portion 32 at each corner portion 33. In other words, a ridge 35 having a larger curvature than the curvature of the parting line PL at each corner portion 33 is formed at the boundary between the arcuate periphery 32B and the back surface 32C at each corner portion 33.

[0040] Next, the operation of the mounting structure 10 for the decorative item 30 according to this embodiment configured as above will be described.

[0041] 1 to 5, the decorative device 30 is attached to the upholstery material 12 by sandwiching a part of the upholstery material 12 between the main body 32 of the decorative device 30 and the back plate 20, i.e., by placing the main body 32 of the decorative device 30 in a recess 24 of the back plate 20 together with a part of the upholstery material 12. The depth of the recess 24 of the back plate 20 is set to be greater than or equal to the thickness of the main body 32, and preferably greater than or equal to the sum of the thickness of the main body 32 and the thickness of the upholstery material 12. Therefore, the decorative device 30 does not have a design surface 34 that protrudes from the surface of the upholstery material 12.

[0042] Furthermore, in the skin material 12, slits 17 are formed that continue from the through holes 16 through which the protrusions 36 are inserted toward the areas where the peripheral edges (more specifically, the corners 33) of the main body 32 of the decorative device 30 are disposed. Therefore, even if the skin material 12 is formed relatively thick (for example, in the three-layer structure described above), the pressure applied to the skin material 12 can be alleviated by the widening of the slits 17. This makes it possible to prevent wrinkles from occurring in the skin material 12 near the peripheral edges (more specifically, the corners 33) of the decorative device 30.

[0043] Furthermore, small hole portions 17Fs and 17Rs are formed at the ends of each slit portion 17 (the portions farthest from the through hole 16). Therefore, even if the skin material 12 is distorted so that the slit portion 17 widens when the protrusion portion 36 is inserted into the through hole 16, the skin material 12 continues from the slit portion 17 and is prevented from breaking beyond the length of the slit portion 17.

[0044] Furthermore, a push nut 40 is fitted onto the protrusion 36 inserted into the through hole 26 of the back plate 20. In other words, the protrusion 36 is fixed by the push nut 40. Therefore, compared to a configuration in which the outer diameter of the protrusion 36 is formed to be larger than the inner diameter of the through hole 26 and the protrusion 36 is press-fitted into the through hole 26 and fixed to the back plate 20, it is possible to more reliably prevent the decorative item 30 from coming off the skin material 12 (back plate 20).

[0045] Also, as shown in FIG. 7, when viewed from a direction perpendicular to the thickness direction of the main body 32 of the decorative device 30, the portion from the parting line PL formed on the peripheral portion (at least each corner portion 33) of the main body 32 toward the front surface (design surface 34) is a straight-line peripheral portion 32A, and the portion from the parting line PL toward the back surface 32C is an arc-shaped peripheral portion 32B.

[0046] Therefore, at least in each corner portion 33, the decorative device 30 (each corner portion 33 of the main body 32) reduces the pressing force that pushes the skin material 12 present near each corner portion 33 into the recess 24, as compared to a case in which, for example, the peripheral edge portion on the back surface 32C side from the parting line PL intersects with the back surface 32C at approximately a right angle (the corner portion 33 is approximately 1 / 4 cylindrical).

[0047] As a result, even if the skin material 12 is formed relatively thick (e.g., in a three-layer structure), when the main body 32 of the decorative element 30 is accommodated in the recess 24 of the back plate 20 together with a portion of the skin material 12, the occurrence of wrinkles in the skin material 12 near the peripheral portions (more specifically, each corner portion 33) of the decorative element 30 can be effectively prevented.

[0048] Also, as shown in FIG. 8, at the back surface 32C of each corner portion 33 of the main body 32 of the decorative device 30, more specifically, at the boundary portion between the arc-shaped peripheral portion 32B and the back surface 32C at each corner portion 33, a ridge portion 35 having a smaller curvature than the curvature of the parting line PL at each corner portion 33 is formed (at the boundary portion between the arc-shaped peripheral portion 32B and the back surface 32C at each corner portion 33, a ridge portion 35 having a larger radius of curvature than the radius of curvature of the parting line PL at each corner portion 33 is formed).

[0049] Therefore, compared to when a ridge portion (not shown) with a curvature greater than the curvature of the parting line PL is formed at the boundary between the arcuate peripheral portion 32B and the back surface 32C at each corner portion 33, the curvature of the arcuate peripheral portion 32B at each corner portion 33 is gentler (gently spherical), and the pressing force by the decorative device 30 (each corner portion 33 of the main body portion 32) to press the skin material 12 present near each corner portion 33 into the recess 24 is further reduced.

[0050] As a result, even if the skin material 12 is formed relatively thick (e.g., in a three-layer structure), when the main body 32 of the decorative element 30 is accommodated in the recess 24 of the back plate 20 together with a portion of the skin material 12, the occurrence of wrinkles in the skin material 12 near the peripheral portions (more specifically, each corner portion 33) of the decorative element 30 can be more effectively prevented.

[0051] In addition, the parting line PL is the most that can be seen from the appearance of the design surface 34 of the decorative element 30. Therefore, even if the parting line PL is formed into an arc-shaped peripheral portion 32B toward the back surface 32C, there is no risk that the arc-shaped peripheral portion 32B will impair the design of the decorative element 30. Similarly, even if a ridge portion 35 is formed at the boundary between the arc-shaped peripheral portion 32B and the back surface 32C, there is no risk that the ridge portion 35 will impair the design of the decorative element 30.

[0052] Furthermore, when the decorative tool 30 (main body 32) is attached to the back plate 20 with the skin material 12 sandwiched therebetween, the multiple small protrusions 37 provided on the back surface 32C of the decorative tool 30 (main body 32) bite into the surface of the skin material 12, so that the skin material 12 can be more effectively sandwiched between the decorative tool 30 (main body 32) and the back plate 20. Therefore, it is possible to suppress or prevent the decorative tool 30 from shifting in position relative to the skin material 12, compared to a configuration in which the multiple small protrusions 37 are not provided on the back surface 32C of the decorative tool 30 (main body 32).

[0053] The above describes the mounting structure 10 for the decorative tool 30 according to the present embodiment based on the drawings, but the mounting structure 10 for the decorative tool 30 according to the present embodiment is not limited to the one shown in the drawings, and can be appropriately modified in design within the scope of the present invention. For example, the shape of the positioning protrusion 38 is not limited to the one shown in the drawings, and may be formed, for example, into a substantially cylindrical shape. Furthermore, the number and positions of the small protrusions 37 are not limited to those shown in the drawings.

[0054] Also, although not shown, the tip of the protrusion 36 may be formed with an expanded diameter portion larger than the inner diameter of the through hole 26 of the back plate 20, and the axial center portion of the protrusion 36 may be hollowed out so that the expanded diameter portion of the protrusion 36 can elastically deform radially inward. With such a configuration, the protrusion 36 is inserted into the through hole 26 with the expanded diameter portion elastically deformed radially inward, and then returns to its original state, thereby being locked so as not to come out of the through hole 26. Therefore, in this case, the push nut 40 can be omitted. [Explanation of symbols]
