JPS6027057Y2 - Lid for storage box for small items in automobile interior - Google Patents

Description

[Detailed Description of the Invention] This invention relates to a lid for a small article storage box such as a glove box or a console box of an automobile.

Conventionally, the structure of the lid of this type of automobile interior storage box is as follows:
As shown in the attached drawing, FIG. 5, which is a cross-sectional view of a main part thereof, a surface member called an outer is formed by integrally filling a cushioning member 22 such as a polyurethane resin between an insert member 21 such as an iron plate and a skin 23. 24 and a back member 25 called an inner, which is usually made of a plastic molded product, are generally molded separately and then fixed together with screws 26 or the like.

However, separately molding the front member 24 and the back member 25 not only increases the number of steps per se.

These assemblies require special parts and processes for fixing, such as spot welding the nut 27 to the insert member 21.

This invention provides a lid that can simplify these steps at once, and at the same time proposes a lid that is excellent in terms of cushioning properties and tactility.

Furthermore, this device can extremely easily and integrally form various uneven parts on the outer surface of the stopper or handle part that is essential for the function of the lid body, or the placing part of the tip provided as necessary. A lid body that can be provided.

This is what we propose.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of this invention will be described below with reference to the accompanying drawings, with respect to a lid of a glove box of an automobile.

Figure 1 shows a glove box G that is an embodiment of this invention.
The lid body 10 is an overall perspective view, FIG. 2 is a sectional view thereof, and FIG. 3 is an enlarged sectional view of the main part.

As shown in the figure, the lid body 10 according to this invention has an insert member 11 made of an iron plate or a synthetic resin molded product inside.
The outer surface 10a is provided with an appropriate uneven portion 12 such as a stopper 12a1 placement portion 12b or a handhold portion 12c.
The outer surface 10a including the uneven portions 12 is mainly composed of a polyurethane resin foam 15 integrally formed with It is covered with a thin coating film 13, and the portions close to the coating film 13 and the insert member 11 are made of a polyurethane resin skin layer 15a with extremely fine bubbles or almost non-foamed state, and the other skin layers 15 are covered with a thin coating film 13.
The inner layer portion surrounded by a is characterized by being composed of a polyurethane resin foam layer 15b having relatively large cells.

That is, when obtaining the lid body 10 of this invention, the fourth
As shown in the figure, a coating film 13 is formed in advance by spraying, for example, an elastic urethane paint on the surface of the cavity 18 of a mold 19 having a cavity 18 corresponding to the outer surface shape of the lid body 10. Thereafter, the insert member 11 is set at a predetermined position within the mold.

If necessary, it is also desirable to apply an adhesive to the surface of the insert member 11.

Then, the mold 19 is closed, and a known polyurethane resin solution for Integrus Kind foam is injected and filled into the cavity, and the foam is fixed.

Note that the thickness of the coating film 13 on the outer surface is usually 3 to 4 μm.
It is colored in an appropriate color to match the color tone inside the car.

Further, as is clear from the drawings, in this invention, various uneven portions 12 on the outer surface of the lid body, such as a stopper, a placing portion, a handhold portion, etc., are also integrally formed.

Among these uneven parts 12, the curved parts such as the stopper 12a were conventionally molded separately and attached to the lid body, but in this invention, the lid body is made of polyurethane resin foam. Since it is molded, there is an advantage that such elastic pieces can be integrally formed.

As described above, this invention greatly simplifies the process of forming the lid body compared to the conventional method of assembling the inner and outer parts, and has great advantages in terms of work efficiency and cost reduction.

Furthermore, since the outer surface of the lid is formed of polyurethane resin foam and a coating film, the cushioning properties are enhanced and the product is also excellent in safety as an automobile part.

Furthermore, since the thin coating film on the outer surface is integrated with the polyurethane resin skin layer adjacent to it, it has excellent tactility and is resistant to peeling and cracking due to friction of the surface layer. This invention has many advantages as a lid for a storage box for small items for automobiles.

In addition, although the lid of the glove box was described in the embodiment, it goes without saying that the same applies to the lid of a console box and other small article storage boxes for automobiles.
