Description

BACKGROUND OF THE INVENTION

[0001] The present invention relates to composite fabric sheet for use on side faces of a sports shoe, and particularly to a piece of composite fabric sheet sewn to a preset hole or opening on each side face of a sports shoe for variation or change in style. The composite fabric sheet is wear resistant, durable, bendable, flexible, extensible and air permeable in nature. Thereby, such a composite fabric sheet is practical and comfortable for use.

[0002] In general, there are several kinds of fabric sheets sewn to the inner sides of through holes of a shoe's side faces to make a shoe embodiment varied in styles and appealing to eyes. Such fabric sheets appear in the following types.

[0003] 1. The first one is illustrated in the U.S. Pat. No. 586,137 issued on Jul. 13, 1897, of the so called sanitary shoes. It has an obvious disadvantage in use. The shoe embodiment is made of leather or plastics and has on the side faces a number of longitudinal elongated slots in parallel to one another with a belt fixed at both ends formed between every two slots whereby a plurality of laterally disposed belts are interwoven in a crisscross manner with the fixed belts to form a plurality of air permeating fissures. These air permeating fissures can function well but the interwoven belts are not extensible, causing a wearer to feel uncomfortable in walking and wearing.

[0004] Another kind of prior art as shown in the U.S. Pat. No. 3,497,971 issued on Mar. 3, 1970 is related to an upper material for shoes. This material has a disadvantage in practical use. The upper material A is made up of interwoven belts a, c obtained by cutting a whole piece of fabric sheet into a plurality of belts. Then the upper material A is cut into pieces 2, 3 which are sewn to a shoe embodiment B, the upper material A so produced is not soft and extensible enough to make a wearer of such kind of shoes feel comfortable.

[0005] A third prior art relates to a sports shoe made of composite rubber sheet material disclosed in U.S. Pat. No. 4,858,339 issued on Aug. 22, 1989. This material has a following disadvantage in practical use. The composite rubber sheet is made up of a piece of bottom cloth 3, a sponge rubber sheet 2 of proper depth and a mesh cloth 1 having a percentage of voids in the range of 15 to 75%. The mesh cloth 1 is deeply engaged with the sponge rubber sheet 2. Such a composite rubber sheet applied to sports shoes has good extensibility, elasticity, durability and wear resistance. However, the sponge rubber sheet 2 has poor air permeability, making a wearer of the shoes feel uncomfortable.

SUMMARY OF THE INVENTION

[0006] Therefore, the primary object of the present invention is to provide a composite fabric sheet for sports shoes, which is made up of a piece of superficial cloth and elastic inner mesh cloth, the superficial cloth is made up of a plurality of weaving bands and elastic bands that are interwoven together in a crisscross manner. Such a composite fabric sheet is extensible and air permeable in practical use so as to make a wearer of shoes feel comfortable and convenient.

[0007] Another object of the present invention is to provide a composite fabric sheet for sports shoes. The inner side of the fabric sheet is a mesh cloth of elasticity and air permeability and the outer side thereof is made up of interwoven weaving bands and elastic bands whereby wide range air passages can be formed when the composite fabric sheet is forced to extend to make air permeable via the passages, rendering the interior of a shoe dry and comfortable.

[0008] One further object of the present invention is to provide a composite fabric sheet wherein as the superficial cloth is extended, in the inner side at the crossing points of the weaving bands and the elastic bands without adhesive material can be elastically extended to naturally form a wide range buffer air passages which can absorb compact force. Thereby, the relative reduction of compact can enhance wear resistance and comfort of shoes.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0013] Referring to FIG. 1, the composite fabric sheet 20 of the present invention is applied to the side faces of a sports shoe embodiment 10. The composite fabric sheet 20 is made up of a piece of superficial cloth 21 and a piece of inner mesh cloth22. The superficial cloth 21 is made up of weaving bands 211 and elastic bands 212 crisscrossed and overlapped in the longitudinal and lateral directions to interweave together into a composite fabric sheet with a proper thickness and width and durability.

[0014] The weaving bands 211 are of proper thickness, width and wear resistance. The elastic bands 212 are also of proper thickness, width and elasticity. After the weaving bands 211 and elastic bands 212 are interwoven, the superficial cloth 21 of the composite fabric sheet can be naturally extended in either longitudinal or lateral directions. The inner mesh cloth 22 is a piece of air permeable mesh cloth provided with a plurality of meshes and is extensible in four directions. As the composite fabric sheet 20 is produced, as shown in FIG. 2, the superficial cloth 21 is coated with thermal adhesive on the back thereof by thermal rollers so as to permit the inner cloth 22 to be attached thereto in a random manner or in either longitudinal or lateral directions. The weaving bands 211 and elastic bands 212 of the superficial cloth 21 are partially or alternatively engaged with the inner mesh cloth 22 by adhesive so as to permit the crossing points of the weaving bands 211 and the elastic bands 212 to be free of the adhesive.

[0015] Referring to FIG. 3, in assembly, the perspective diagram of the present invention shows that the composite fabric sheet 20 is cut into pieces of various shapes in advance for use and the pieces are fixedly sewn to the shoe embodiment 10 or the shoe embodiment 10 is provided with through holes or openings and corresponding pieces of the composite fabric sheet are sewn to the shoe embodiment 10 from the interior of the same.

[0016] Referring to FIG. 4, the operation mode of the present invention is illustrated. The composite fabric sheet 20 of the shoe embodiment 10 will extend and deform as a result of the insertion of a foot; at the same time, at the crossing points of the inner sides of the interwoven weaving bands 211 and the elastic bands 212 are free of adhesive can be extended in the elastic bands direction so as to form a wide ranged buffer air passages 23 of proper size so as to permit air to pass therethrough.

[0017] There are a number of advantages obtained in the present invention given as below:

[0018] 1. The superficial cloth 21 of the composite fabric sheet 20 has elastic bands 212 in the longitudinal or lateral direction and the associated inner mesh cloth 22 at the bottom is also elastic in nature, permitting the composite fabric sheet applied to shoes to extend. Thus a wearer of shoes feels easy to wear and comfortable.

[0019] 2. The inner side of the composite fabric sheet 20 is made of mesh cloth with elasticity and air permeability; and the outer side of the same is made of cloth including interwoven weaving bands 211 and elastic bands 212. As a result of the extension of the elastic bands 212, at the crossing points with the elastic bands 212 will form a plurality of air passages whereby ventilation takes place among the meshes of the inner mesh cloth 22, making the interiors of shoes dry and comfortable.

[0020] 3. When the superficial cloth 21 is extended, the air passages formed on the inner side without adhesive at the crossing of the weaving bands 211 and elastic bands 212, the elastic bands 212 can extend freely to form buffer-like air passages 23 which can absorb compact, making the composite fabric sheet 20 wear resistant as a result of the reduction of compact. It makes a wearer feel comfortable.
