Description

  The present invention relates to an interior part for a vehicle such as an automobile door trim in which an edge of a centering member that partially covers the surface of the interior part body is fitted into a grained groove provided in the interior part body.

  In this type of interior part, from the viewpoint of decorativeness and design, for example, a grained groove surrounding a rectangular region is formed in the interior part body molded of a resin material or the like, and the grained groove is inscribed in the grained groove. It is configured by embedding the edge of the member and attaching the inscribed member to the interior part main body.

Then, simply inserting the edge of the inscribed member into the grained groove does not produce a mounting force of the inscribed member on the interior part body.For example, it is inserted into the grained groove in the inscribed member (ornament skin material). Protrusions are provided at the edges of the parts to be inserted with a required gap, while insertion holes corresponding to the protrusions are provided at the bottom of the wood grain groove of the interior part body (trim board). Then, the tip of the projecting piece is projected to the back side of the interior part main body through each insertion hole, the projecting portion is folded back to the back side of the wood grain groove, and the folded base is provided on each back side of the wood grain groove. It is configured to be clamped and fixed by a lid that closes (see Patent Document 1).
JP2003-267152A.

  However, in the above-described conventional technology, the protruding portion of the inscribed member is sandwiched by closing the insertion hole with a lid provided on the back side of the grained groove, and the inscribed member is fixed to the interior component main body. Therefore, depending on the size of the fitting gap between the insertion hole and the lid, there is a possibility that the lid inserted due to the vibration of the automobile or the like may come off from the insertion hole, thus preventing such detachment. Therefore, it is necessary to set the dimensional relationship so that the fitting gap between the insertion hole and the lid is very small. In this case, the assembling operation becomes difficult.

  Therefore, conventionally, it has been widely used to bond the end portion of the inscribed member into the grained groove using an adhesive.

  Conventionally, the following two methods are widely adopted as a method of attaching the end portion of the inscribed member using an adhesive.

  As one method, the adhesive material is inserted in the grained groove in advance, and then the end of the inscribed member is inserted into the grained groove, and the end of the inscribed member is inserted by the inserted adhesive. Adhesive fixing.

  In this case, the grained groove is formed in a very narrow groove shape, so it is difficult to insert the adhesive, and even if it can be inserted successfully, depending on the amount of the inserted adhesive, the adhesive If it leaks to the surface of the interior part main body or the adhesive overflows when the end of the incline member is inserted, the interior part itself will also deteriorate in appearance, so it adheres to the grained groove. The material insertion work requires skill.

  Therefore, another method has been proposed and already adopted. In this manner, as shown in FIG. 4, the interior part main body a has a pair of side vertical walls b and c facing each other and a groove bottom d that connects one end sides of both side vertical walls b and c to each other. A grained groove e formed by the groove wall is formed, and the surfactant layer f is applied to one side vertical wall c of the pair of side vertical walls c, d of the grained groove e, and the grained groove Adhesive material i is affixed in advance to the back surface of the inscribed member g to be grained in e, and when the grained edge h is grained into the grained groove e, the adhesive material acts on one side vertical wall b. Adhering to the other side vertical wall c side so as not to adhere due to the action of the agent layer f, the woodworking edge h is wooded into the woodworking groove e, so that the intermediate member g is stretched over the interior component body a. It is configured by mounting (see FIG. 5).

  However, in order to glue the grained edge h of the inscribed member g into the grained groove e, first, as shown in FIG. 4, the side of the grained edge h to which the adhesive material i is applied is attached to the surfactant layer. In the state facing the f side, the grained edge h is grained into the grained groove e. At this time, the grained edge h is grained while partially scratching the surfactant layer f. Finally, the adhesive material i is bonded to the other side vertical wall d, but the scratched surface active agent layer f in the graining process of the graining edge h has nowhere to go, so It may overflow from the groove e and adhere to the surface of the interior part main body a.

  If the surface active layer f overflows and adheres to the surface of the interior part main body a, it will solidify white after drying, resulting in a poor appearance. For this purpose, it is necessary to completely wipe off the surfactant layer f overflowing on the surface of the interior part main body a in a subsequent process, which is troublesome.

  Therefore, in view of such points, the present invention prevents the surfactant layer from overflowing from the wood groove into the surface of the interior component body when the wood grain edge of the inscribed member is wooded into the wood groove of the interior component body. The purpose is to provide interior parts for automobiles.

  In order to achieve the above-mentioned object, the present invention comprises an interior part main body constituted by a groove wall having at least a pair of side vertical walls facing each other and a groove bottom that connects one end sides of both side vertical walls to each other. Forming a grained groove, applying a surfactant layer on one side vertical wall of the pair of side vertical walls of the grained groove, and forming the grain member in the grained groove Attaching an adhesive material to the back side in advance, when the grained edge into the grained groove, so that the adhesive material does not adhere to the one side vertical wall by the action of the surfactant layer, An interior part for a vehicle constituted by adhering an end face to the other side vertical wall side and embedding the wood grain edge into the wood grain groove so as to stretch and attach the intermediate member to the interior part body. And a groove wall constituting the grained groove , Is characterized in that the formation of the peeling surfactant discharge hole for discharging the surfactant peeled from surfactant layer when writing grain the Kimekomi edge in the Kimekomi groove outside Kimekomi groove.

  With this configuration, when the grained edge is grained into the grained groove, even if the grained edge scratches and peels off the surfactant layer, the peeled surfactant passes through the peeling surfactant discharge hole. Because the surfactant is discharged from the back side of the interior part body and the surfactant does not overflow from the grained groove and adhere to the surface of the interior part body, it is necessary to wipe off the overflowed surfactant in the subsequent process. However, it is possible to provide interior parts that have a very good appearance.

  In the present invention, the release surfactant discharge hole is formed in a part of the other side vertical wall or in the groove bottom, so that it is reliably scratched from the surfactant layer. The surfactant thus peeled off is discharged from the back side of the interior part main body through the release surfactant discharge hole.

  The interior part for automobiles according to the present invention configured as described above has a peeled interface even if the grained edge is scratched and separated when the grained edge is scratched into the grained groove. The activator is discharged from the back side of the interior part body through the release surfactant discharge hole, and the surfactant does not overflow from the grain groove and adhere to the surface of the interior part body. Therefore, it is possible to provide an interior part having a very good appearance without the need for wiping off the overflowing surfactant.

  Embodiments in the best mode for carrying out the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view depicting a door trim with a centering member, which is a general automotive interior part, and FIG. 2 is a cross-sectional view taken along line AA of FIG. 1 depicting one embodiment of the present invention.

  A door trim, one of the interior parts of an automobile, has an armrest portion 2 extending in the front-rear direction of the vehicle body so as to crawl the upper portion from the substantially central portion on the front side which is the passenger compartment side, and a pocket located in the substantially central portion on the lower side. A door trim main body 1 as an interior part main body provided with a speaker grille 4 positioned on the part 3 or the front side of the vehicle body is configured, and an intermediate member 5 is provided on the upper side of the armrest portion 2 in the door trim main body 1. Is installed.

  In order to stretch and attach the inscribed member 5 to the door trim body 1, first, a pair of side vertical walls 6 a and 6 b and the side vertical walls 6 a and 6 b are placed around the inscribed member installation site of the door trim main body 1. A wood-grooved groove 6 having a U-shaped cross section composed of groove bottoms 6c connected to each other is formed in advance, and the wood-meshing edge 5a of the wood-engaging member 5 is wooded into the wood-meshing groove 6 so that the wood-engaging member 5 is made into a door trim body 1 is stretched.

  For this purpose, of the pair of side vertical walls 6a, 6b of the grained groove 6, the surfactant layer 7 is applied and formed on one side vertical wall 6a, and the inscribed member is grained into the grained groove 6 For example, the adhesive material 8 is applied in advance (or laminated) to one end surface 5b of a pair of opposite end surfaces 5b and 5c of the opposite edge 5a of the graining edge 5a, and the graining edge 5a is placed in the graining groove. 6, the adhesive material 8 is prevented from adhering to one side vertical wall 6 a by the action of the surfactant layer 7, and the end surface 5 c is adhered to the other side vertical wall 6 b so The intermediate member 5 is stretched and attached to the door trim main body 1 by embedding the end edge 5a in the grain groove 6.

  Further, of the pair of side vertical walls 6a, 6b constituting the groove wall, the wood groove 6 includes a corner portion where the other side vertical wall 6b and the groove bottom 6c are connected to each other. In part, a release surfactant discharge hole 9 is formed.

  With this configuration, when the grained edge 5a is grained into the grained groove 6, even if the grained edge 5a scratches and peels off the surfactant layer 7, the peeled surfactant 7a is removed from the surfactant. The discharged surfactant 9a is discharged from the back side of the door trim main body 1 through the discharge hole 9, and the scratched surfactant 7a overflows from the wood groove 6 to the surface side of the door trim main body 1 and adheres to the surface of the door trim main body 1. Therefore, it is not necessary to wipe off the overflowing surfactant layer 7 in the subsequent process, and it is possible to provide an interior part having a very good appearance.

  FIG. 3 shows another embodiment according to the present invention.

  In FIG. 3, the release surfactant discharge hole 9 is formed in the groove bottom 6 c including a corner portion where the groove bottom 6 c constituting the groove wall of the grain groove 6 and the other side vertical wall 6 b are connected, The surfactant layer has a different configuration from the above-described embodiment, and the other configurations are the same. The surfactant layer scratched when the demarcated edge 5 a is grained into the setting groove 6 by the release surfactant discharge hole 9. 7 is discharged from the back side of the door trim body 1 to the outside.

  As described above, in the present invention, when the grained edge is grained into the grained groove, even if the grained edge scratches and peels off the surfactant layer, the peeled surfactant is separated from the peeling interface. Since the surfactant is discharged from the back side of the interior part body through the activator discharge hole, and the surfactant does not overflow from the grained groove and adhere to the surface of the interior part body, it overflows in the subsequent process. In order to provide interior parts that do not require wiping off the agent and have a very good appearance, the interior parts are provided with the edge of the intermediate member that partially covers the surface of the interior parts body. It is suitable for interior parts for vehicles such as a door trim of an automobile which is fitted with a wood grain in a groove.
