Description

  The present invention relates to a technique for improving a decorative part for a vehicle.

  Not only vehicles but also decorative parts in which jewels and imitations of jewels are bonded to a holding body are widely known. As one of them, a glass in which a fixing body such as a gemstone or a gem imitation is bonded to a glass for glasses as a holding body is known (for example, see Patent Document 1 (FIG. 3)).

  In the decorative part known from Patent Document 1, an adhesive is applied to a bottomed hole formed in a conical shape on a holding body, and the fixed body is bonded by pressing the fixed body against the adhesive. The bonding surface of the fixed body is formed in a conical shape along the wall surface of the bottomed hole.

  On the other hand, in recent years, the use of a fixed body having an adhesive surface formed in a flat shape is increasing. An adhering body having an adhesive surface formed in a flat shape has high versatility and is inexpensive, and is therefore easy to use for various decorative parts. When the bonding surface of the fixed body is a flat surface, the bonded surface is often formed in a flat shape in accordance with this shape. By forming each other in a planar shape, the amount of adhesive required can be minimized.

  However, according to these decorative parts, including those disclosed in Patent Document 1, the adhesive is extruded by the fixed body when the fixed body is bonded. The extruded adhesive may protrude from the gap between the fixed body and the holding body to the design surface side. The protruding adhesive solidifies as it is on the design surface. The adhesive solidified on the design surface causes the appearance to deteriorate. In particular, when a fixed body having a bonding surface and a surface to be bonded formed in a flat shape is used, the adhesive easily protrudes from the design surface. There is room for improvement in this regard.

Utility Model Registration No. 3103063

  An object of the present invention is to provide a vehicle decorative component having a high appearance in a vehicle decorative component in which an adhesive surface and a bonded surface are formed in a flat shape.

  The invention according to claim 1 is a vehicle decorative part comprising a holding body having a bottomed hole formed on a design surface, and a fixed body bonded to the bottom surface of the bottomed hole. It is formed of a planar adherend surface, a recess recessed at the center position of the adherend surface, and a relief groove recessed at the peripheral position of the recess, and the fixed body has an adhesive layer on the adherend surface and the recess. And the escape groove is an adhesive escape groove.

  The invention according to claim 2 is characterized in that the adhesive layer is continuously formed across the recess, the adherend surface and the clearance groove.

  The invention according to claim 3 is characterized in that the concave portion is formed in a tapered shape.

  In the invention which concerns on Claim 1, the relief groove dented in the peripheral position of the recessed part is formed. This relief groove is a relief groove for the adhesive. That is, by pressing the fixed body, the adhesive protrudes from between the bonded surface and the bonded surface of the fixed body. The protruding adhesive flows into a relief groove that is recessed at the peripheral position of the adherend surface. For this reason, it is possible to prevent the protruding adhesive from protruding onto the design surface. That is, it is possible to improve the appearance of the vehicle decorative part in which the bonding surface and the bonded surface are formed in a flat shape.

  In addition, in the invention according to claim 1, the concave portion is formed at the center position of the adherend surface. The recess serves as a mark for the application position when the adhesive is applied. In the case of performing an adhesive application operation, the adhesive is applied toward the recess. By forming the concave portion at the center position of the adherend surface, central convergence can be ensured. Further, when the adhesive is pushed by the fixed body, the adhesive can be extended over the entire adhesion surface and the adherend surface. The bonding area of the bonding surface and the bonded surface can be increased, and the fixed body can be bonded with high strength.

  In the invention which concerns on Claim 2, the contact bonding layer is continuously formed over a recessed part, a to-be-adhered surface, and a relief groove. That is, the adhesive layer is formed on the entire escape groove. By increasing the area where the adhesive layer is formed, the adhesive strength of the adhesive layer to the relief groove can be increased. By adhering the fixed body to such an adhesive layer, the fixed body can be bonded with high strength. That is, since the adhesive layer is formed from the recess to the escape groove, it has a so-called anchoring effect that prevents the fixed body from being detached from the holding body.

  In the invention which concerns on Claim 3, the recessed part is formed in the taper taper shape. An application device such as a syringe may be used for the adhesive application operation. In this case, in a state where the tip of the syringe is in contact with the tapered surface of the recess, the coating device is advanced toward the bottom of the recess. Then, the tip end portion of the syringe is guided toward the center of the bottom surface of the recess by the side surface of the recess formed in a tapered shape. Since it is guided toward the center, the adhesive can be more applied to the center of the recess. Thereby, the adhesion area of the adhesion surface and the adherend surface can be reliably increased.

First, Embodiment 1 of the present invention will be described with reference to the drawings.
FIG. 1 shows a vehicle decorative component 30 attached to a side mirror 20 as an attached body. The side mirror 20 shown in the figure is attached to the left side of the vehicle, and is shown in a state viewed from the front to the rear of the vehicle.

  The side mirror 20 has a support portion 21 attached to the vehicle body 11, a housing 22 extends from the support portion 21 toward the outside of the vehicle, a mirror 23 is accommodated in the housing 22, and a winker lamp 24 is attached. . A vehicle decorative component 30 is bonded to the upper side of the blinker lamp 24 attached to the side mirror 20. The vehicle decorative component 30 will be described in detail with reference to FIG.

  As shown in FIG. 2, in the vehicular decorative component 30, a holding body 40 is bonded to the side mirror 20 via double-sided tapes 31, 31, and diamond imitation is performed on the holding body 40 via an adhesive layer 32. An adhering body 60 using is adhered.

  The holding body 40 has a substantially M shape in a cross-sectional view, a holding portion 41 that holds the fixing body 60 at the center, and leg portions 42 that extend from both ends of the holding portion 41 toward the surface of the side mirror 20. 42 and ribs 43 and 43 extending to the side mirror 20 between the leg portions 42 and 42 and the holding portion 41. For the holding body 40, for example, an injection molded product made of ABS (Acrylonitrile Butadiene Styrene) resin can be adopted.

  The fixed body 60 includes an adhesive surface 61 bonded to the adhesive layer 32, a fixed body side surface 62 raised from the adhesive surface 61, and a design surface 63 exposed from the end of the fixed body side surface 62 to the outside of the vehicle. Consists of. For the fixed body 60, imitation of various colors can be used in addition to imitation of glass or resin diamond. Moreover, jewelry can also be used and any material can be selected as long as it can be attached for the purpose of decorating the side mirror 20.

  A bottomed hole 50 is formed in the holding portion 41 of the holding body 40 from the outside of the vehicle toward the surface of the side mirror 20. The bottomed hole 50 includes a tapered side surface 51 and a bottom surface 52. The bottom surface 52 includes a planar adherend surface 53, a recess 54 that is recessed at the center position of the adherend surface 53, and a relief groove 55 that is recessed at the peripheral position of the adherend surface 53. The concave portion 54, the adherend surface 53, and the escape groove 55 are formed concentrically.

  The escape groove 55 is preferably circular with the recess 54 as the center, but may be formed at the periphery of the recess 54. That is, it can be formed in an arbitrary shape such as an ellipse, an oval, or a rectangle. The reason why a circular shape centered on the recess 54 is desirable will be described later.

  Referring also to FIG. 3, the concave portion 54 includes a tapered tapered concave side surface 54 a and a circular concave shape at the tip of the concave side surface 54 a and a flat concave bottom surface 54 b.

  The clearance groove 55 is substantially U-shaped in a cross-sectional view, and extends from the edge of the adherend surface 53 toward the side mirror 20 and from the end of the groove inner peripheral surface 55a to the side mirror 20. The groove portion bottom surface 55b extends substantially parallel to the groove portion bottom surface 55b, and the groove portion outer peripheral surface 55c extends substantially parallel to the groove portion inner peripheral surface 55a.

  The portions 41 a to 43 a of the holding portion 41, the leg portions 42, and the ribs 43 facing the double-sided tape 31 are formed flush with each other. By making the surfaces flush, each of the holding portion 41, the rib 43 and the leg portion 42 can be bonded to the double-sided tape 31. Since all of these are bonded, the bonding area is wide and high bonding strength can be ensured.

  An end portion of the leg portion 42 is a protruding portion 42 b that protrudes toward the side mirror 20 from a portion facing the double-sided tape 31. By forming the protruding portion 42b, the gap α formed between the holding body 40 and the side mirror 20 is reduced, and the double-sided tape 31 is difficult to visually recognize. Thereby, the external appearance property of the decorative component 30 for vehicles including the side mirror 20 (attachment body 20) can be improved.

  In the cross-sectional view, the fixed body 60 has at least a part of the side surface 62 of the fixed body overlapping the escape groove 55. Thereby, it becomes difficult to visually recognize the escape groove 55 from the outside, and the appearance of the vehicle decorative component 30 can be improved.

  Further, the depth D of the side surface 51 of the bottomed hole 50 is deeper than the height H of the fixed body 60. A gap β is inevitably generated between the fixed body 60 and the side surface 51. There is a possibility that the escape groove 55 is visually recognized from the gap β. However, by forming the bottomed hole 50 deep with respect to the fixed body 60, the shadow of the side surface 51 and the shadow of the fixed body 60 are covered with the gap β. That is, it is possible to suppress the escape groove 55 from being visually recognized by the shadow. This can improve the appearance.

  The adhesive layer 32 is continuously formed across the recess 54, the adherend surface 53, and the escape groove 55. That is, the adhesive layer 32 is formed on the entire escape groove 55. By increasing the area where the adhesive layer 32 is formed, the adhesive strength of the adhesive layer 32 to the escape groove 55 can be increased. By adhering the fixed body 60 to such an adhesive layer 32, the fixed body 60 can be bonded with high strength.

  Note that any double-sided tape and any adhesive can be adopted as the adhesive constituting the double-sided tape 31 and the adhesive layer 32. The assembly of the vehicle decorative component 30 will be described in detail in the following drawings.

  As shown in FIG. 4, first, a holding body 40 in which a plurality of bottomed holes 50 are formed and a fixing body 60 having the same number of bottomed holes 50 are prepared. The sizes of the bottomed hole 50 and the holding body 40 may be different one by one. Further, the arrangement of the bottomed hole 50 in the holding portion 41 is also arbitrary.

  Next, as shown in FIG. 5A, the syringe 71 faces the recess bottom surface 54 a, and the adhesive 82 filled in the syringe 71 is injected into the recess 54.

  Since the concave portion 54 is small, the distal end portion 71 a of the syringe 71 may come into contact with the edge of the concave portion 54 as shown in FIG. From this state, as indicated by the arrow (1), the syringe 71 is lowered toward the recess bottom surface 54b.

  As shown in FIG. 6B, by lowering, the distal end portion 71 a of the syringe 71 is guided toward the center of the concave portion 54 by the concave side surface 54 a. Adhesive 82 is applied with the distal end portion 71a of the syringe 71 facing the concave bottom surface 54b.

  As shown in FIG. 5B, when the adhesive 82 is applied to the recess 54, the adhesive surface 61 of the fixed body 60 is pressed toward the adhesive 82. Since the fixed body 60 is small, for example, when the fixed body 60 is handled, an air tweezer 72 is used.

  By pressing the fixing body 60, the adhesive 82 spreads and adheres to the entire adhesive surface 61 as shown in FIG. When the adhesive 82 is solidified, an adhesive layer (reference numeral 32 in FIG. 3) is formed.

  According to the present invention, the relief groove 55 that is recessed at the peripheral position of the recess 54 is formed. The relief groove 55 is a relief groove for the adhesive 82. That is, the adhesive 82 protrudes from between the adhesion surface 61 and the adherend surface 53 by pressing the fixing body 60. The protruding adhesive 82 flows into the relief groove 55 that is recessed at the peripheral position of the adherend surface 53. For this reason, it is possible to prevent the protruding adhesive 82 from protruding onto the design surface. That is, it is possible to improve the appearance of the vehicle decorative part in which the bonding surface 61 and the bonded surface 53 are formed in a flat shape.

  In addition, a recess 54 is formed at the center position of the adherend surface 53. The recess 54 serves as a mark for the application position when the adhesive 82 is applied. When performing the operation of applying the adhesive 82, the adhesive 82 is applied toward the recess 54. Since the concave portion 54 is formed at the center position of the adherend surface 53, central convergence can be ensured. Further, when the adhesive 82 is pushed by the fixed body, the adhesive 82 can be extended over the entire adhesive surface 61 and the adherend surface 53. The bonding area of the bonding surface 61 and the bonded surface 53 can be increased, and the fixed body 60 can be bonded with high strength.

  Further, as shown in FIG. 6, the recess 54 is formed in a tapered shape. An application device such as a syringe 71 may be used for the application work of the adhesive 82. In this case, the syringe 71 is moved forward toward the concave bottom surface 54b in a state where the tip 71a of the syringe 71 is in contact with the tapered surface (the concave side surface 54a) of the concave. Then, the distal end portion 71a of the syringe 71 is guided toward the center of the concave bottom surface 54b by the concave side surface 54a formed in a tapered shape. Since it is guided toward the center, the adhesive 82 can be applied to the center of the recess 54 more. Thereby, the adhesion area of the adhesion surface 61 and the adherend surface 53 can be reliably increased.

  With reference to FIGS. 3 to 5, the concave portion 54, the adherend surface 53, and the relief groove 55 are formed concentrically. As a result, the adhesive 82 applied to the recess 54 spreads evenly on the adherend surface 53. Since it spreads evenly, the adhesive layer 32 can be formed on the entire adherend surface 53. Further, due to the concentric shape, the adhesive 82 on the adherend surface 53 falls evenly into the escape groove 55. More adhesive 82 can be stored in the escape groove 55 than in the case of falling intensively on a part.

  Further, the adhesive layer 32 is continuously formed across the recess 54, the adherend surface 53, and the escape groove 55. That is, the adhesive layer 32 is formed on the entire escape groove 55. By increasing the area where the adhesive layer 32 is formed, the adhesive strength of the adhesive layer 32 to the escape groove 55 can be increased. By adhering the fixed body 60 to such an adhesive layer 32, the fixed body 60 can be bonded with high strength. That is, since the adhesive layer 32 is formed from the concave portion 54 to the escape groove 55, it has a so-called anchoring effect that prevents the fixed body 60 from being detached from the holding body.

  Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 7 shows a cross-sectional configuration of the vehicle decorative part of the second embodiment, corresponding to FIG.

  As shown in FIGS. 7 and 8, the decorative component 30A for the vehicle according to the second embodiment has three positioning protrusions 53a that protrude from the adherend surface 53 of the holding body 40A toward the design surface. . Also in the vehicle decorative part 30A formed as described above, the predetermined effect of the present invention can be obtained.

  In addition, when the fixing body 60 is fixed, the fixing body 60 may be pushed until the adhesive surface 61 comes into contact with the positioning protrusion 53a. The positioning of the fixed body 60 is facilitated, and the bonding work of the fixed body 60 is facilitated. Further, the amount of the adhesive 82 existing between the bonding surface 61 and the bonded surface 53 is constant. For this reason, it is possible to prevent the adhesive 82 from overflowing from the escape groove 55 due to excessive pressing of the fixing body 60.

  Next, Embodiment 3 of the present invention will be described with reference to the drawings. FIG. 9 shows a decorative part for a vehicle according to the third embodiment, corresponding to FIG.

  As shown in FIG. 9, in the vehicle decorative component 30B according to the third embodiment, a plurality of escape grooves 55B are formed in the holding body 40B. These escape grooves 55 </ b> B are formed so as to draw a substantially rectangular shape with the recess 54 as the center. Also in the vehicle decorative part 30B formed as described above, the predetermined effect of the present invention can be obtained.

  Next, a fourth embodiment of the present invention will be described with reference to the drawings. FIG. 10 shows a vehicle decorative part according to the fourth embodiment, which is shown in correspondence with FIG.

  As shown in FIG. 10, in the decorative component 30C for a vehicle according to the fourth embodiment, a plurality of escape grooves 55C are formed in the holding body 40C. These escape grooves 55C are formed radially about the recess 54. Even in the vehicle decorative part 30C formed as described above, the predetermined effect of the present invention can be obtained.

  In addition, although the decorative component for vehicles by this invention was applied to the side mirror in embodiment, it is applicable also to the other site | part outside a vehicle, and a vehicle interior. In addition, the present invention can be applied to a two-wheeled vehicle other than the four-wheeled vehicle, and the use is not limited to these as long as it is used for the purpose of decorating the vehicle.
