Description

[Detailed Description of the Invention] The present invention relates to a console box lid, and relates to a reinforcing structure for an inner lid body.

As shown in Figure 1, the conventional console box lid consists of a flat synthetic resin inner lid a covered with a soft covering material. Therefore, the strength is insufficient, and since the layer of the covering material is thick, a large amount of expensive semi-rigid foamed polyurethane resin is required.

In addition, in order to eliminate such defects, as shown in Fig. 2, a covering material is insert-molded into the insert material C, and this insert material C is screwed onto the inner cover a to form a hollow part d inside. There is something configured.

Although this lid is stronger than the lid shown in FIG. 1 and saves on covering material, it requires more man-hours for assembly and still lacks strength.

In view of the above-mentioned drawbacks, the present invention has been developed by protruding a reinforcing wall to form a large number of small chambers on the top surface of an inner lid made of synthetic resin, and connecting the inner lid to the reinforcing wall with a blocking member made of foamed polyurethane resin. It is covered with a covering material and reinforced by a protruding reinforcing wall to form a large number of small chambers, and the blocking member prevents the covering material of the small rooms within the reinforcing wall from interfering with the reinforcing wall, saving on covering material and reducing weight. This is an attempt to make the world more popular.

Next, an example of the implementation of the present invention will be described with reference to the accompanying drawings FIGS. 3 and 4.

Reference numeral 1 denotes an inner lid made of a synthetic resin plate, and a reinforcing wall 5 made of a peripheral wall 3 and a partition wall 4 is integrally protruded from the upper surface of the inner lid 1 to form a large number of small chambers 2. There is.

The shape of the small chamber 2 may be one consisting of concentric and radial partition walls 4 as shown in FIG. 4, or a honeycomb shape as shown in FIG.
Alternatively, there is a partition wall 4 made of a combination of straight lines and waves as shown in FIG.

Furthermore, a sheet-shaped blocking member 6 made of synthetic resin film, synthetic paper, paper, etc. is stretched over the top surface of the reinforcing wall 5, and the peripheral edge of this blocking member 6 is fixed to the peripheral wall portion 3 of the reinforcing wall 5 by adhesive or welding. has been done.

Further, the upper and peripheral surfaces of the reinforcing wall 5 are integrally covered with a covering material 11 made of a soft to semi-hard foamed polyurethane resin.

In addition, when the blocking member 6 is made of a sheet-like material that is easily deformable and is made of synthetic resin film, synthetic paper, paper, etc. with a thickness of 0.1 mm to 1.0 mm, it is necessary to install a shield at the bottom of the inner lid 1 for each small chamber 2. A ventilation hole 7 having a small diameter is opened outward in a tapered shape.

Note that if the thickness of the blocking member 6 made of synthetic resin film, synthetic paper, or paper is 2 mm or more, it is not necessary to open the ventilation hole 7.

A mounting piece 9 having a hinge portion 8 is integrally formed on the inner lid 1, and this mounting piece 9 is attached to the console box 10.

Next, the operation of the above embodiment will be explained.

First, during manufacturing, the blocking member 6 is fixed to the inner cover 1, which has been injection-molded integrally with the reinforcing wall 5. Next, this inner cover 1 is inserted into a polyurethane foam mold, and then a polyurethane resin stock solution is poured into the mold. The coating material 11 is formed by injecting or injecting.

At this time, if the blocking member 6 is made of synthetic resin with a thickness of about 0.1 mm to 1.0 mm, or a film or sheet material that easily deforms such as synthetic paper or paper, the reaction heat of the polyurethane resin during molding (70 ℃~80℃), the air in the sealed small chamber 2 expands and deforms the blocking member 6, so that the surface coating material 11 becomes uneven when removed from the mold as shown in FIG. In a low-temperature atmosphere, it tends to become dented as shown by the dotted line.

For this purpose, a ventilation hole 7 is opened at the bottom of each small chamber 2 to expel the air inside.

Furthermore, even if a sheet-like material such as synthetic resin film, synthetic paper, or paper is used for the blocking member 6, if it is a plate-like material with a thickness of 2 mm or more, the blocking member 6 may be damaged by the expansion of the air in the small chamber 2. Since there is no risk of deformation, there is no need to form the ventilation holes 7.

According to the present invention, since an integral reinforcing wall is provided protruding from the upper surface of the synthetic resin inner lid to form a large number of small chambers, it is possible to increase the strength against pressing force from the vertical direction. Furthermore, since the reinforcing wall was covered with a covering material made of foamed polyurethane resin through a blocking member, the composite material did not intervene in the small chamber, keeping the small chamber hollow and reducing weight, and reducing the waste of the covering material. It is possible to prevent the injection of water and save material.

In addition, if the blocking member is a sheet-like material that is easily deformable and is made of synthetic resin film, synthetic paper, paper, etc. with a thickness of 1 mm or less,
By opening a ventilation hole in the bottom of the inner lid for each small chamber, the air is not sealed inside the small chamber, and the shielding member is prevented from being deformed due to the expansion of air during molding, and the appearance is damaged. You can prevent it from being damaged.
