Description

[Detailed Description of the Invention] << Industrial Application Field >> The present invention relates to an improvement of a spare tire cover designed to improve aesthetics and protect it in view of deterioration of appearance and damage to the spare tire due to exposure. .

<< Prior Art >> Conventionally, spare tires for automobiles are most commonly stored in a recess provided in a floor panel in a trunk room. Attempts have been made to cover the spare tire with a spare tire cover in order to improve the appearance and protect the spare tire, and the tendency has recently been increasing.

The spare tire cover is formed in a shape having a bulge on the outside and a recess on the inside according to the concavo-convex shape of the spare tire, and is sewn using a vinyl chloride resin sheet or a non-woven fabric as a material, or a vinyl chloride resin sheet or There are those formed by vacuum forming using a polyolefin resin sheet or the like, or those formed by press forming using a forming nonwoven fabric or forming felt as a material.

<Problems to be solved by the device> However, in the case of sewing using a vinyl chloride resin sheet or a non-woven fabric as a material, a flat object is sewn to form a shape, so that the degree of freedom in shaping is low and the cost is high. There is a problem. In addition, a product formed by vacuum forming using a vinyl chloride resin sheet, a polyolefin resin sheet, or the like as a material has a problem that a high-grade feeling is not obtained.

On the other hand, a non-woven fabric for molding or a felt formed by press molding has a large degree of freedom in molding, is inexpensive, and gives a high-class feeling. Although it is superior in terms of products, wrinkles due to excess thickness are generated in the outer bulge when simply press-molding.Therefore, in order to prevent the wrinkles, tension is applied to the non-woven fabric for molding or the felt for molding. Is press molded. For this reason, this type of spare tire cover has a problem in that molding strain remains and deformation occurs due to heat, moisture, etc.

The present invention has been made in view of the above circumstances, and its purpose is to have a large degree of freedom in modeling, the cost is low, a high-class feeling is obtained, and wrinkles do not occur. Is to provide a spare tire cover that can reliably prevent problems such as deformation due to heat and humidity.

<< Means for Solving the Problem >> In order to achieve the above object, the present invention relates to a spare tire cover formed by press molding a molding non-woven fabric or a molding felt into a shape that substantially matches the outer shape of the tire. It is characterized in that a plurality of radial bead-shaped portions for restricting the generation of wrinkles during molding are set from the central portion to the outer peripheral portion of the spare tire cover.

<Operation> According to the configuration of the present invention described above, the excess thickness, which is a factor of wrinkle generation during press molding, is expanded and absorbed by the bead-shaped portion, so wrinkle generation can be prevented, and this is also In the case of materials such as nonwoven fabrics for molding, it can be achieved without applying tension, so no molding strain remains,
It is also possible to prevent defects such as deformation due to heat and moisture.

<< Embodiment >> An embodiment according to the present invention will be described below with reference to FIGS.

1 to 3, the spare tire cover 1 is formed by press molding using a molding non-woven fabric or a molding felt as a material, and a bulge portion 2 is bulged outward in accordance with the uneven shape of the spare tire (not shown). Has a recessed portion 3 formed therein.

Twelve bead-shaped portions 5 are formed at equal angular intervals from the vicinity of the outer peripheral edge of the bottom of the recess 3 to the outer peripheral edge 4. The bead-shaped portion 5 forms a groove-shaped concave portion at a predetermined position of the upper die for pressing, and forms a convex portion at a portion corresponding to the concave portion of the lower die for pressing to form the concave portion and the convex portion at the time of mold clamping. Are formed by engaging with each other with a gap of appropriate size. In this case, at the height of the bead-shaped portion 5,
Wrinkles are more likely to occur as the depth of the concavo-convex shape of the spare tire cover corresponding to each type of spare tire becomes deeper. Therefore, it is advisable to increase the height according to this depth to absorb the excess thickness.

In the above-described embodiment, the bead-shaped portion 5 extends the extra thickness and absorbs the excess thickness in the bead-shaped portion 5. A wrinkle does not occur and a spare tire cover with an excellent product appearance can be obtained. Further, since the material such as the non-woven fabric for molding is not applied with tension, no molding strain remains, and it is possible to prevent the problem that the material is deformed by heat, moisture or the like. Further, the bead-shaped portion 5 has a reinforcing effect, and the bead-shaped portion 5 provides a strong feeling.

FIG. 4 shows another embodiment in which a surface material 6 such as a non-woven fabric for molding is laminated with a skin material 6 such as a decorative PVC sheet or a colored non-woven fabric. In this case, the product aesthetics can be further improved.

<Effect> As described above, according to the present invention, in a spare tire cover molded by press molding using a non-woven fabric for molding or a felt for molding, a plurality of bead-like shapes are formed from the inside to the outer peripheral edge. Since the part is formed, it has a high degree of freedom in molding and can be manufactured at low cost, and it is possible to obtain a high-grade feeling and not to generate wrinkles, and it is also possible to prevent defects such as deformation due to heat, humidity, etc. In addition, the strength can be improved, and a strong feeling can be obtained.
