Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a mounting structure for a decorative molded product having an internal space.

2. Description of the Related Art In general, examples of vehicle accessories as decorative molded products having an internal space include a front grill G, a wheel cover W, a finisher F, etc. as shown in FIGS. 11 and 12.

To explain this in terms of the finisher F, the finisher F has a horizontally elongated clear cap C on the outer surface of the main body, as shown in FIGS. 13 and 14. This clear cap C is made of a colorless transparent or colored transparent synthetic resin that transmits light, and is integrally molded with an outer surface portion _C1 and a side wall portion _C2 protruding toward the inner surface of the outer surface portion _C1 . It is attached by adhesively fixing the end face of the side wall portion _C2 with a liquid adhesive/sealant E so that the interior space _C3 is shielded by the mounting surface of the finisher F.

Problems that the invention aims to solve: However, with this mounting structure, it is difficult to achieve a perfect seal, and rainwater, car wash water, etc. can enter the internal space from the point where the internal space _C3 of the clear cap C cannot be kept airtight. There is a risk. The reason for this is that it is difficult for the liquid adhesive to penetrate into the sharp corners of the clear cap, and after spraying the adhesive E around the entire circumference of the clear cap C on the main body side of the finisher F, the clear cap C is Since the space C3 is crimped, the air inside the space _C3 breaks the adhesive E and escapes to the outside, which tends to cause unsealed parts. In addition to this, even if the internal space _C3 can be kept airtight during the bonding process of the clear cap C, when the finisher F becomes hot, the internal air in the space _C3 expands and the clear cap C floats up. This may lead to a situation where the seal with the finisher F is destroyed.

Furthermore, when the above-mentioned clear cap C is attached, the adhesive E protrudes into the inner space of the clear cap C and is visible from the transparent outer surface _C1 side, which impairs the decorativeness.

Means for Solving the Problems In the mounting structure of a decorative molded product having an internal space according to the present invention, a waterproof sheet is fixed to the side wall of the decorative molded product to keep the internal space airtight, and the side of the waterproof sheet is fixed to the side wall of the decorative molded product. The decorative molded product is fixed to a predetermined surface of the object to be attached, with the decorative molded product facing the object to be attached.

Function In this mounting structure for decorative molded products, a waterproof sheet is stretched over the end face of the side wall to keep the internal space airtight and fix the decorative molded product to the object to be installed. Not only can the sealing properties be maintained without relying on adhesives, but even when the air inside the decorative molded product expands, the waterproof sheet can flex and deform to absorb the expansion force. Since the agent does not protrude into the interior space of the decorative molded product, the aesthetic appearance will not be impaired even if the decorative molded product is made of transparent synthetic resin.

Embodiments The following description will be made with reference to FIGS. 1 to 10.

This embodiment is applied to a vehicle finisher 10 as shown in FIGS. 1 and 2, and a clear cap 20 is fixed to a main body portion 11 formed in a concave or groove shape.

As shown in detail in FIG. 3, the clear cap 20 is a horizontally elongated one having a space 23 therein between an outer surface portion 21 and a frame-shaped side wall portion 22 protruding from the inside of the outer surface portion 21. or colored transparent
It can be integrally molded from synthetic resin such as PMMA or PC. With this clear cap 20, the outer surface 2
The inner surface of the finisher 1 can be decorated with a large number of irregularities 24 such as protrusions, grooves, or die cuts as shown in FIG. The flange portion 25 may also be formed to extend outward. Further, the left and right end surfaces of the side wall portion 22 are provided with openings or recesses 1 provided on the side surfaces of the recess of the finisher 10.
An engaging portion 26 that fits into the side wall portion 2 can be provided, and the engaging portion 26 can also be provided on the longitudinal side surface of the side wall portion 22 as necessary.

A waterproof sheet 30 for keeping the internal space 23 airtight is fixed to the clear cap 20 in advance.
For the waterproof sheet 30, metal foil such as stainless steel or aluminum is used to make the metallic luster color visible through the outer surface portion 21, and other colors are made visible or the interior is made invisible. As for the material, suitable materials such as synthetic resin sheets, films, or water-impermeable cloth can be used. The waterproof sheet 30 has an adhesive or pressure-sensitive adhesive layer 31 attached to the inner surface as shown in FIG.
By pressing this against the side wall portion 22 of the clear cap 20 with a press mold P, it can be stretched and fixed to the end surface of the side wall portion 22 as shown in FIG. As the adhesive or pressure-sensitive adhesive layer 31, an appropriate material such as thermosetting or room temperature curing can be used as long as it has water resistance. If the color or pattern of the material needs to be visually checked, it is best to use colorless and transparent materials or colored materials. In addition, even if the adhesive or adhesive layer 31 does not adhere to the waterproof sheet 30, it may adhere to the inner space of the clear cap 20 even if it adheres along the end surface on the side wall 22 side of the clear cap 20 as shown in FIG. The waterproof sheet 30 can be fixed to keep it airtight.

The clear cap 20 to which the waterproof sheet 30 is fixed is prepared by applying, for example, a liquid adhesive/sealant 40 to the bottom edge of the concave body portion 11 of the finisher 10 at predetermined intervals, as shown in FIGS. 1 and 2. , the stretched side of the waterproof sheet 30 can be adhesively fixed to face the inner surface of the bottom. In addition to or instead of adhesive fixing, the clear cap 20 can be securely fixed by fitting a locking part 26 provided on the side wall 22 into the opening or recess 12 of the finisher 10. At this time, if the waterproof sheet 30 is fixed to the end surface of the side wall portion 22 in a flat shape, some space 50 is created between the waterproof sheet 30 and the inner bottom surface of the finisher 10 in order to allow the waterproof sheet 30 to bend and deform. It is best to install them at separate intervals to form a .

With the mounting structure of the decorative molded product constructed in this way, the interior space 23 of the clear cap 20 can be kept airtight and the waterproof sheet 30 can be fixed, so that the situation where rainwater or car wash water invades the interior space 23 of the clear cap 20 can be avoided. do not invite Further, even if the internal space of the space 23 expands, the waterproof sheet 30 can be bent and deformed to absorb the expansion force, so that the airtightness of the internal space 23 is impaired and the clear cap 20 is 10 will not occur. In addition to this, the inner space 23 of the clear cap 20 is
Since it is hidden in advance with 0, clear cap 2
Since the adhesive 40 for adhering 0 to the finisher 10 does not protrude from the edges into the internal space 23, the aesthetic appearance is not impaired.

Note that the above-mentioned waterproof sheet 30 can be formed into a wavy shape as shown in FIG. 7 to promote flexural deformation. Alternatively, as shown in FIG. The sheet 30 can also be fixed. Even if the stretched side of the tarpaulin sheet 30 is fixed in contact with the inner bottom surface of the finisher 10, the tarpaulin sheet 30 can be secured by wrapping the tarpaulin sheet 30 around the side surface of the side wall portion 22 and gluing it as shown in FIG. A space 50 for bending and deforming can be provided. Further, in order to enhance its decorativeness, a decorative member 32 such as an identification pattern may be provided on the inner surface as shown in FIG.

Although the above-mentioned embodiment exemplifies the case where a clear cap is attached to a finisher, the present invention can similarly be widely applied to attaching decorative moldings to a front grill, a wheel cover, etc.
