Description

[Detailed description of the invention] (a) Technical field of the invention This invention relates to molded decorative panels for automobile interiors that are used as automobile door trims, rear parcel shells, molded ceilings, etc. This product has a three-layer structure in which a skin material is attached to the surface of a substrate made of a molded product using a patch material, and can be attached to a desired location such as a body using clips or screws inserted into the mounting holes of the substrate.

(b) Prior Art This type of molded decorative board has a structure as shown in FIG.
A substantially pot-shaped mounting hole 2 having a diameter a and a small diameter hole portion 2b.
A patch material 3 such as urethane foam is adhered to the surface side of the substrate 1, and a skin material 4 such as a vinyl chloride sheet is attached by vacuum forming or the like to cover the surface side of the patch material 3. . Note that when bonding the pad material 3 to the surface of the substrate 1, a padding paper 5 is interposed so that the peripheral edge of the mounting hole 2 is not bonded. For example, the clip 6, which is a stopper, is prevented from coming off by inserting its head 6a into the large-diameter hole 2a of the mounting hole 2 of the board 1 from the back side, and then laterally shifting it toward the small-diameter hole 2b. Clips 6 attached and multiple attached in this way
The entire molded decorative board can be attached by fitting and locking the protruding portion 6b toward the back side of the substrate 1 into a desired location such as the body of an automobile.

By the way, in the conventional configuration described above, when the clip 6 is attached to the attachment hole 2 of the board 1, the head part 6a pushes up the pad material 3 through the backing paper 5, and the area around the clip attachment part is pushed up. Skin material 4
becomes locally raised. For this reason, there were problems in that it looked bad and was unsightly for interior use, and also had a bad feel.

(c) Purpose of the invention This invention was created in view of the above circumstances, and is intended to allow fasteners such as clips to be conveniently attached to the mounting holes of the board, and to prevent the pad material and skin material from bulging due to the head of the fastener. , there are no bulges at all, and there are no concave dents, and the exterior design is very good and looks good, and even when you touch the surface material with your hand, there is no difference from other surface parts, so you don't feel any unevenness or foreign body sensation. The purpose is to provide extremely high quality molded decorative laminates for automobile interiors.

(d) Structure of the invention In order to achieve the above-mentioned object, the present invention provides a board having a mounting hole in which the head of a fastener such as a clip or screw can be inserted from the back side and moved sideways to prevent it from coming off. In the molded decorative panel for automobile interiors in which a skin material is attached to the surface side of the board through a patch material, a large-diameter recess is formed at the peripheral edge of the mounting hole of the substrate on the surface side that contacts the patch material, and the recess is A spacer having a substantially U-shaped cross section whose surface becomes flush with the substrate surface when fitted into the space, and which forms a space on the back surface between the inner bottom surface of the recess and in which the head of the stopper can be slid laterally. It is characterized in that it is configured by providing.

With the above configuration, the head of the fastener such as a clip is accommodated in the space on the back side of the spacer in the recess of the board so that it can be slid laterally, so that the fastener can be conveniently attached to the board mounting hole, and
Since the surface of the spacer is flush with the substrate surface, the pad material and skin material on the front side will not swell, bulge, or concave at all, giving it an extremely attractive appearance. In addition to being of good quality, even if you press your hand against the surface material, it will not change from other surface parts, and you will not feel any unevenness or foreign body sensation.It is of extremely high quality.

(e) Embodiment of the invention An embodiment of the invention will be explained below with reference to FIGS. 2 and 3. In the figure, reference numeral 11 denotes a slightly thick board, and reference numeral 12 denotes mounting holes formed at multiple locations on the board 11 (only one location is shown and the others are omitted). Communicating large diameter hole 1
2a and a small diameter hole 12b. Reference numeral 13 is a relatively thin flat pad material having a cushioning property such as urethane foam that is adhered to the surface side of the substrate 11, and 14 is a vinyl chloride sheet or the like that is pasted on the surface side of the pad material 13 by lamination or the like. It is a skin material. In addition,
In the figure, reference numeral 16 denotes a stopper that is attached to the mounting hole 12 of the board 11 with a portion protruding toward the back side thereof, that is, a split type clip made of a synthetic resin molded product (this is a well-known type that is already widely used). Therefore, detailed explanation will be omitted). The process up to this point is substantially the same as the conventional example described above.

Here, in the present invention, a large-diameter, substantially elliptical recess 11A is formed at the peripheral edge of the surface side of the mounting hole 12 of the substrate 11 that is joined to the pad material 13. On the other hand, a flat elliptical disc-shaped spacer 17 that fits into the recess 11A of the substrate 11 is provided. This spacer 17 is a molded product made of synthetic resin, and has a rising side wall 17a at the periphery of the back side so as to have a substantially U-shaped cross section.
1A, the surface 17b becomes the substrate 11.
The head 1 of the clip 16 is flush with the surface of the clip 16, and the head 1 of the clip 16 is flush with the surface of the recess 11A on the back side.
The structure is such that it constitutes a space 17c in which the device 6a is accommodated. The space 17c is large enough to allow the head 16a to move smoothly when the clip 16 is moved from the large diameter hole 12a to the small diameter hole 12b of the mounting hole 12, and is large enough to allow the head 16a to move smoothly relative to the diameter of the small diameter hole 12b. In accordance with the fact that the head base rod portion 16c of the clip 16 has a small diameter so as to have an appropriate play, the space 17c has a large diameter with respect to the head 16a so as not to inhibit the play.

In the molded decorative board having the above-described configuration, the spacer 17 is fitted into the recess 11A from the surface side of the substrate 11 in which the mounting hole 12 and the recess 11A are formed.
In this way, the surface of the substrate 11 is flattened together with the surface of the spacer 17, and in this state, the skin material 14 is attached to the surface side of the substrate 11 with the patch material 13 interposed therebetween. The molded decorative board manufactured in this way has its substrate 11
Insert the head 16a of the clip 16 through the large diameter hole 12a of the mounting hole 12 from the back side of the
With the clip 16 entered into the back space 17c, the clip 16 is moved laterally to the small diameter hole 12b and installed in a manner that prevents it from coming off. In this way, one clip 16 is attached to each attachment hole 12 of the board 11,
In this state, the protruding portions 16b of each clip 16 toward the back surface of the substrate 11 are firmly pushed into pre-formed clip receiving holes (not shown) on the inner surface of an automobile body, etc., to fit and lock the molded decorative board. It becomes possible to install it as an interior material.
In addition, if each clip 16 is misaligned with respect to each clip receiving hole at this time, it is easy to adjust the position by moving within the range of play with respect to the small diameter hole 12b of the mounting hole 12 and the space 11c of the spacer 17. can be done. In this way, the attached molded decorative board does not swell or bulge at the clip attachment part of the front surface side of the patch material 13 or the skin material 14, and is flat like the other surface parts.
Not only does it fit very well, but it also feels exactly the same.

(f) Other Embodiments Figures 4 and 5 each show other embodiments of this invention, and the one in Figure 4 uses a simple clip as a stopper, different from the split clip 16 of the above embodiment. 16A (known), and the one in Fig. 5 is an example in which a special screw 16B with a flat head 16Ba is used as a fastener, and in both cases, the structure other than the fastener itself is the same as above. Since it is similar to the embodiment, the same reference numerals are given to the drawings and the explanation is omitted, but the same effects as described above can be obtained.

(g) Effects of the invention Since this invention has been made as detailed above, it is possible to conveniently attach a clip or other stopper to the mounting hole of the board, and the head of the stopper prevents the bulge of the patch material and skin material. It has no protuberances and is equally flat with other parts, has a very good appearance, and does not change from other surface parts even when touched with the hand, making it extremely effective for interior decoration.
