The door trim 1 includes a core material 2 formed by molding a board or the like into a required shape, and a core material 2 of the core material 2. It is composed of a skin material 3 such as a cloth that is integrally attached to the surface and improves the surface feel and surface appearance.

A lock finisher 4 made of a long resin molding is attached to the pivot side edge of the door trim 1, that is, the lock side.

To attach the lock finisher 4, use a bracket 5 as shown in FIG.
Is fixed to the core material 2 of the door trim 1 by the rivets 6, and then the screw mounting boss hole 7 formed in the bracket 5 and the screw hole 4a formed in the lock finisher 4 are aligned with each other. By locking and fixing the screws 8, the lock finisher 4 is attached along the back surface of the door trim 1 on the lock side.

<Problems to be Solved by the Invention> However, in the conventional lock finisher 4 mounting structure, the bracket 5 is first riveted to the rear side of the door trim 1 and then the bracket 5 is screwed into the screw mounting boss hole 7. Since the lock finisher 4 is fixed with a screw, it requires a lot of man-hours for mounting, which causes a problem of cost increase.

Further, the bracket 5 is attached to the door trim 1 with the rivets 6.
It is also pointed out that the head of the rivet 6 appears as a convex portion on the surface of the door trim 1 in order to fix it to the core material 2 and deteriorates the aesthetic appearance of the product.

This invention was made in view of such circumstances,
The object of the present invention is to significantly reduce the number of steps for mounting the lock finisher in the mounting structure of the lock finisher made of a resin molded body that is mounted along the lock side edge of the door trim, and to greatly contribute to cost reduction. (EN) Provided is a lock finisher mounting structure for an automobile door trim, which does not cause a convex portion on the surface of the product and has an improved external appearance.

<Means for Solving the Problems> In order to achieve the above-mentioned object, the present invention has an elongated shape along the vertical direction of the rotating side edge of a door trim in which the surface of a core material is covered with a skin material. In a lock finisher mounting structure in a door trim in which a lock finisher made of a resin molded body is mounted, in a recess formed on the front surface side of the core material and a through hole on the bottom surface of the recess, a plate having a boss integrated is housed in the recess. In addition to fixing, the boss is inserted into the through hole, and a lock finisher installed in a lap shape on the back side of the rotating side of the door trim is fixed to the boss hole of the boss with a screw so as to be attached.

<Operation> As is apparent from the above configuration, according to the present invention, the plate is housed in the recess formed in the surface of the door trim core,
By inserting the boss formed on the plate into the through hole provided in the recess and fixing it with a screw to the boss hole, the lock finisher can be attached to the back side of the door trim, eliminating the conventional riveting. You can
It is possible to prevent deterioration of the aesthetic appearance due to the head of the rivet protruding to the surface.

Furthermore, since the rivet stop can be eliminated, the number of mounting steps can be significantly reduced.

<< Embodiment >> An embodiment of a lock finisher mounting structure according to the present invention will be described in detail below with reference to the accompanying drawings.

FIG. 1 is a perspective view of an essential part showing a rotary side end edge of a door trim and a lock finisher attached to this part. In the drawing, a door trim 10 is formed by molding a hard board, a resin board or the like into a required shape. Made of core material 11
In FIG. 1, a part is cut away for convenience of explanation, but a skin material 12 is attached to the front surface side of the core material 11 and the terminal is wound around and fixed to the back surface side of the core material 11. Has been done.

Along the rotating edge of the door trim 10, that is, along the lock side, a lock finisher 20 made of a long resin molding is attached to the back side of the door trim 10 so as to partially wrap it. In the core material 11 on the side of the door trim 10, recesses 13 are provided at several positions at appropriate intervals, and through holes 14 are formed in the bottom surface of the recess 13.

An attachment hole 21 is also formed on the lock finisher 20 side so as to correspond to the through hole 14 formed in the core material 11.

Then, the plate 30 having an outer shape that substantially matches the shape of the recess 13 is housed in the recess 13 and is fixed by adhesion with an adhesive, and the back surface of the plate 30 is inserted into the through hole 14. The mounting boss 31 is integrated.

Therefore, after the lock finisher 20 is positioned on the back side of the door trim 10 and the plate 30 is fixed in the recess 13 provided in the core material 11 of the door trim 10 with an adhesive, the screw 40 is pushed from the back side of the lock finisher 20. By fixing with a screw in the mounting hole 21 of the lock finisher 20 and the boss hole 31a of the mounting boss 31 of the plate 30, the lock finisher 20 can be securely fixed to the door trim 10 side as shown in FIG. Compared with the installation man-hours of, the man-hours can be significantly reduced.

Further, since the core material 11 and the surface of the plate 30 are substantially flush with each other, the head of the rivet does not appear as a convex portion on the surface as in the conventional case, and the surface appearance and the surface feel are remarkably good. Therefore, the specification of the skin material 12 is not limited to the thick specification, and the thin specification skin material can be used, and the degree of freedom in material selection is expanded.

Next, FIGS. 3 and 4 show a second embodiment of the lock finisher mounting structure according to the present invention. In this embodiment, as shown in FIG. If the embossed convex portion 22 is set on the finisher 20 and the same screw fixing as in the above-described embodiment is performed, the fourth portion is obtained.
As shown in the figure, even if the back surface of the core material 11 of the door trim 10 and the convex portion 22 come into contact with each other and press the front surface side of the door trim 10, the convex portion 22 of the lock finisher 20 receives this pressing force. Since there is no need to interpose an adhesive between the plate 30 and the core material 11, the number of man-hours for mounting the plate 30 can be further reduced as compared with the above embodiment, and further cost reduction can be expected.

<< Advantages of the Invention >> As described above, the lock finisher mounting structure in the door trim according to the present invention has the following special effects.

According to the present invention, the plate is housed and fixed in the recess provided in the core material of the door trim, and the lock finisher is fixed to the mounting boss provided on the back surface of the plate with a screw to fix the lock finisher to the door trim side. Since it can be easily and surely installed, it has an effect that the number of installation steps can be significantly reduced and a significant cost reduction can be achieved as compared with the conventional lock finisher installation structure.

According to the present invention, the plate used for mounting the lock finisher is housed and fixed in the core recess of the door trim, and the lock finisher is screwed and fixed through the mounting boss provided on the back side of the plate. Since the core material surface and the plate surface of the door trim surface where the lock finisher is attached are set to be almost flush with each other, the rivet head by rivet fixing appears as a convex portion on the product surface as in the past, and the product appearance In addition, the product feel is not deteriorated, the appearance and design are remarkably improved, and the feel is also improved.

According to the present invention, even if a relatively thin skin material is used,
Since the convex portion does not appear on the surface of the product as in the conventional case, there is an additional effect that the restriction on the thickness of the skin material used for the door trim can be relaxed and the degree of freedom in material selection can be significantly improved.
