Title:
Plastic or rubber sole structure with variational stripes
Kind Code:
A1


Abstract:
Plastic or rubber sole structure with variational stripes, composed of a striped layer and a sole body. The striped layer and the sole body are combined by thermal pressing and injection molded. The striped layer is made in such a manner that a fabric sheet is placed in a mold and plastic or rubber material is filled onto one face of the fabric sheet and thermally pressed to combine with the fabric sheet and form a thin striped layer. Simultaneously, the surface of the fabric sheet is thermally embossed with continuous stripes. The bottom face of the fabric sheet is formed with a plastic layer or rubber layer. The sole body is made by injection molding to form the configuration of the sole. The bottom face of the sole body is recessed to form at least one connecting sink. The striped layer is snugly attached to and accommodated in the connecting sink of the sole body. Then, the striped layer is thermally integrally fused with the connecting sink of the sole body. The striped layer can be embossed with different stripes so as to vary and beautify the appearance of the sole structure.

Description:

BACKGROUND OF THE INVENTION

[0001] The present invention is related to a plastic or rubber sole structure with variational stripes. A striped layer is combined with the bottom face of the sole body. A fabric layer of the striped layer presents various stripes so as to vary and beautify the appearance of the sole and reduce the plastic or rubber material used in the sole.

[0002] FIG. 1 shows a conventional sole structure 10 which is made of plastic or rubber material by pressing and injection molding. The front section of the bottom face 11 of the sole 10 is embossed with an area of continuous stripes 12. Accordingly, the stripe area 12 and the sole 10 are integrally made of the plastic or rubber material.

[0003] The above structure has the following advantages:

[0004] 1. The sole structure 10 is made of plastic or rubber material by integral pressing and injection molding. Therefore, the stripe area 12 and the sole 10 are both made of the plastic or rubber material. Accordingly, increased plastic or rubber material is consumed and it is necessary to manufacture multiple molds so that the manufacturing cost is higher.

[0005] 2. The sole structure 10 is made of plastic or rubber material by integral pressing and injection molding. Only the front section of the bottom face 11 of the sole 10 is integrally embossed with fixed pattern of stripes 12. The appearance of the sole 10 is monotonous.

SUMMARY OF THE INVENTION

[0006] It is therefore a primary object of the present invention to provide a plastic or rubber sole structure with variational stripes. A striped layer is combined with the bottom face of the sole body. A fabric layer of the striped layer presents its own colors or stripes. Therefore, the bottom face of the sole is not completely plastic or rubber-made so as to reduce the amount of used plastic or rubber material. Moreover, only one mold is needed to create various stripes or colors so as to beautify the appearance of the sole and lower manufacturing cost.

[0007] It is a further object of the present invention to provide the above plastic or rubber sole structure with variational stripes, in which the material of the fabric layer of the striped layer is replaceable so that various stripes or colors of fabric layers can be used to provide various stripes and colors for the sole and thus beautify the appearance thereof.

[0008] The present invention can be best understood through the following description and accompanying drawings wherein:

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] Please refer to FIG. 2. The sole 20 of the present invention is composed of a striped layer 21 and a sole body 22. The striped layer 21 and the sole body 22 are combined in such a manner that they are placed in a mold and thermally pressed and injection molded. The striped layer 21 is made in such a manner that a fabric sheet 211 with a certain size is placed in the mold cavity of a mold. A plastic or rubber material is filled onto one face of the fabric sheet 211 and thermally pressed to combine with the fabric sheet 211 and form a thin striped layer 21 with the same profile as the fabric sheet 211. At the same time, the surface of the fabric sheet 211 is thermally embossed with continuous stripes 212. The bottom face of the fabric sheet 211 is formed with a plastic layer or rubber layer 213. The sole body 22 is made in such a manner that the plastic or rubber material is injected into the mold cavity of the mold and molded to form the configuration of the sole 20. The center of the bottom face 221 of the sole body 22 is recessed to form a connecting sink 222 with the same profile as the striped layer 21.

[0015] When assembled, referring to FIGS. 3 and 4, the striped layer 21 is first placed in the mold cavity of a mold and the sole body 22 is placed in the mold cavity of another mold. Then the two molds are mated with each other to make the plastic or rubber layer 213 of bottom face of the striped layer 21 snugly attached to and accommodated in the connecting sink 222 of the sole body 22. Then, by way of thermal pressing and injection molding, the plastic or rubber layer 213 of bottom face of the striped layer 21 is thermally integrally fused with the plastic or rubber material of the connecting sink 222 of the sole body 22. Accordingly, the stripes 212 or color of the fabric layer 211 of the striped layer 21 on the bottom face 221 of the sole body 22 can present beautiful appearance.

[0016] FIG. 5 shows another embodiment of the present invention, in which the sole 20′ is composed of several striped layers 21 and a sole body 22′. The striped layer 21 and the sole body 22′ are combined in such a manner that they are placed in a mold and thermally pressed and injection molded. The striped layer 21 is made in such a manner that a fabric sheet 211 with a certain size is placed in the mold cavity of a mold. A plastic or rubber material is filled onto one face of the fabric sheet 211 and thermally pressed to combine with the fabric sheet 211 and form a thin striped layer 21 with the same profile as the fabric layer 211. At the same time, the surface of the fabric sheet 211 is thermally embossed with continuous stripes 212. The bottom face of the fabric sheet 211 is formed with a plastic layer or rubber layer 213. The sole body 22′ is made in such a manner that the plastic or rubber material is injected into the mold cavity of the mold and molded to form the configuration of the sole 20′. The center of the bottom face 221′ of the sole body 22′ is recessed to form several connecting sink 222′ with the same profile as the striped layer 21. When assembled, the striped layers 21 are first placed in the mold cavity of a mold and the sole body 22′ is placed in the mold cavity of another mold. Then the two molds are mated with each other to make the plastic or rubber layers 213 of bottom faces of the striped layers 21 snugly attached to and accommodated in the connecting sinks 222′ of the sole body 22′. Then, by way of thermal pressing and injection molding, the plastic or rubber layers 213 of bottom faces of the striped layers 21 are thermally integrally fused with the plastic or rubber material of the connecting sinks 222′ of the sole body 22′. Accordingly, the stripes 212 or color of the fabric layers 211 of the striped layers 21 on the bottom face 221′ of the sole body 22′ can present variational and beautiful appearance.

[0017] The above embodiments are only used to illustrate the present invention, not intended to limit the scope thereof. Many modifications of the above embodiments can be made without departing from the spirit of the present invention.
