JPS584736Y2 - Lid for console boxes, etc. - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a lid for an automobile console box, glove box, etc.

As shown in Figure 1, the lid of a conventional console box is made by placing the lid insert in a mold, which is an injection molded product of ABS resin or a pressed product of iron plate, and casting polyurethane resin to form a skin layer. In addition, the lid inner C is fixed to the lid insert a using screws, and a hollow part d is formed to reduce the weight, but the number of parts is 3. As the molds for molding these, one mold for casting and two molds for injection molding are required, and there is also a step of fixing the beam inner C to the lid insert a during assembly. It was a hassle.

Also, in order to simplify the process, it is conceivable to thicken the skin layer and make the lid insert a a single plate as shown in FIG. 2, but this has the disadvantage of increasing cost and weight.

This invention was developed to solve the above problems, and by forming a soft synthetic resin skin layer on the surface of a synthetic resin core formed by blow molding and having a hollow part, the core can be easily assembled. The hollow part makes it possible to reduce the weight and make the skin layer thinner.

Next, embodiments of the present invention will be described with reference to FIGS. 3 to 5 of the accompanying drawings.

Reference numeral 1 designates a lid body of a console box, glove box, etc., which is made up of a hollow core body 2 and a skin layer 3.

The core body 2 is made of synthetic resin such as polypropylene resin, polyethylene resin, acrylonitrile butadiene styrene synergistic resin, etc., and the lid insert part 12 is formed by blow molding.
and the inner lid part 13 are integrally formed through the hollow part 4, and furthermore, during this molding, the lower end of the lid insert part 12 bulges out in the width direction of the center part 12 toward the hollow part 4 and the inner surface of the inner lid part 13. reinforcing ribs 5 welded to the lid insert portion 12 near one end and the lid inner portion 13
A small protrusion 6.degree. 7 is integrally formed with the inner end of the protrusion 6.degree.7, which is formed so as to bulge inward in a conical shape from the relative position of the protrusion 6.degree.7.

The foamed polyurethane resin skin layer 3 is formed so as to cover the surface side and the surrounding area of the core body 2, and is formed by inserting the core body 2 into a mold and performing injection molding or casting.

Further, a synthetic resin core piece 8 having a thin hinge part 11 in the middle is brought into contact with the position of the small protrusion 6 of the lid inner part 13, and one end is fixed to the small protrusion 6 with a tapping screw 9, and the other end is fixed to the small protrusion 6 with a tapping screw 9. It is fixed to the console box main body 10.

Furthermore, by changing the similar bulging small protrusion 6 to another position, it can also be used for attaching a stopper or a lock.

Next, the operation of this embodiment will be explained.

A lid body 1 is attached via a mounting piece 8 so as to face the top opening of a console box main body 10, and is opened and closed via a hinge portion 11 of the mounting piece 8.

Furthermore, the hollow portion 4 of the core body 2 reduces the weight.

Further, the skin layer 3 serves as a cushioning material due to the elasticity of its soft synthetic resin.

According to the present invention, the lid insert part and the lid inner part that make up the synthetic resin core are integrally formed by blow molding through the hollow part, so it is lightweight, and moreover, it is lighter than the conventional lid insert and lid inner part. Compared to molding and assembling separately, there are fewer parts, so the number of molding steps and molds are reduced, and there is no need for assembly.

In addition, the soft synthetic resin skin layer that covers the surface of this core molds the core.

Because it is formed by inserting it into and molding it,
Two molds, a blow molding mold and a casting mold, are sufficient, and the manufacturing equipment can also be simplified.

Furthermore, since the reinforcing ribs bulge out toward the hollow part and the lid insert part and part of the lid inner are partially welded, the hollow part of the core body is not crushed during the skin layer molding, and the core body deforms. In addition, the hollow core maintains sufficient strength to withstand even if it is pushed by hand after being installed in the console box or loads are applied due to luggage, etc. being placed on the top.

Furthermore, since the reinforcing ribs are molded and welded simultaneously during flow molding of the core, there is no risk of complicating the manufacturing process.
