Abstract
An upper for a shoe includes a shell body having a toe part and a heel part. At least one of the toe part and the heel part is made of a composite material which includes a fabric layer having an outer surface and an inner surface, and an abrasion-resistant coating layer applied to the outer surface of the fabric layer. The coating layer has a thickness of about 0.05-0.25 mm, and is transparent to permit viewing of the outer surface of the fabric layer through the coating layer.
Description
- 1. Field of the Invention
- The invention relates to an upper for a shoe, more particularly to an upper which is light-weight, soft, and abrasion-resistant.
- 2. Description of the Related Art
- Materials used for forming uppers of shoes generally include leather, textile fabrics, vulcanized rubber, and various kinds of plastic materials. Among these materials, leather, vulcanized rubber and injection molded plastic materials are generally used for making toe caps and heel cups of shoes for climbing, hiking and hunting purposes, and have their advantages and disadvantages due to their inherent properties. For instance, while leather is comparatively soft, it is not water-resistant, and is susceptible to wearing and cracking. While vulcanized rubber is durable and resistant to water, it is relatively heavy. As for injected molded plastic materials, they are resistant to water but are not sufficiently durable and soft. In addition, since surface processing of leather and vulcanized rubber is relatively difficult, uppers made therefrom are rather monotonous in design, appearance and color. Expensive or time-consuming patterning techniques, such as transfer printing, will be required if patterns are to be formed on such uppers.
- Therefore, an object of the present invention is to provide an upper which has characteristics of lightweight, softness, durability, and water-resistance.
- Accordingly, an upper for a shoe includes a shell body having a toe part and a heel part. At least one of the toe part and the heel part is made of a composite material which includes a fabric layer having an outer surface and an inner surface, and an abrasion-resistant coating layer applied to the outer surface of the fabric layer. The coating layer has a thickness of about 0.05-0.25 mm, and is transparent to permit viewing of the outer surface of the fabric layer through the coating layer.
- Other features and advantages of the present invention will become apparent in the following detailed description of the preferred embodiments with reference to the accompanying drawings, of which:
-
FIG. 1 is a schematic side view of a shoe incorporating the first preferred embodiment of an upper according to the invention; -
FIG. 2 is an exploded perspective view of the first preferred embodiment; -
FIG. 3 is a sectional view of the first preferred embodiment; -
FIG. 4 is a sectional view of the second preferred embodiment of an upper according to the invention; and -
FIG. 5 is a sectional view of the third preferred embodiment of an upper according to the invention; -
FIG. 1 shows ashoe 100 incorporating the first preferred embodiment of an upper according to this invention. The upper includes ashell body 10 having at least one part made of a composite material. In this embodiment, atoe part 101 and aheel part 102 of theshell body 10 are made of the composite material. Referring further toFIGS. 2 and 3 , the composite material includes afabric layer 11 having anouter surface 111 and an inner surface, and an abrasionresistant coating layer 12 applied to theouter surface 111 of thefabric layer 11. Thefabric layer 11 and thecoating layer 12 are laminated to each other. - The
fabric layer 11 is made of a material selected from the group consisting of nylon, polyester, polycotton, cotton, acetate, and acrylic, and has a measure of softness so that it is comfortable to wear. In addition, thefabric layer 11 is of such a structure that it readily lends itself to a coloration treatment. Theouter surface 111 of thefabric layer 11 can be directly formed to have desired patterns. - The
coating layer 12 is formed from a material resistant to abrasion and water, and is made of a material selected from the group consisting of polyurethane (PU), thermoplastic polyurethane (TPU), and polyvinylchloride (PVC). Thecoating layer 12 has abonding surface 121 that is bonded to theouter surface 111 of thefabric layer 11 by glue or by hot-pressing to form a laminate. Thus, thetoe part 101 and theheel part 102 of theshell body 10 of the upper are abrasion- and water-resistant. Preferably, thecoating layer 12 has a thickness of about 0.05-0.25 mm, and is transparent to permit viewing of theouter surface 111 of thefabric layer 11 through thecoating layer 12. - With the aforesaid construction, the upper of this invention can achieve the following advantageous effects:
- 1. The upper of this invention is relatively more abrasion-resistant compared with conventional uppers.
- 2. As the thickness of the
coating layer 12 is in the range of 0.05-0.25 mm, the upper of this invention is comparatively soft and light, and can be manufactured at relatively low costs. In addition, the upper is not susceptible to creasing during the lasting process. - 3. The upper of this invention has better resistance to water compared with conventional fabric and leather uppers. Moreover, patterns can be easily formed on the
fabric layer 11. As the patterns are protected by thecoating layer 12 covering thefabric layer 11, the appearance of the upper can be maintained. - Referring to
FIG. 4 , in the second preferred embodiment of an upper according to this invention, the composite material forming a part of theshell body 20 includes afabric layer 21 and an abrasion-resistant coating layer 22. Thefabric layer 21 is formed from a water-resistant material such that thefabric layer 21 has a water-resistantouter surface 211. Thecoating layer 22 is provided with a plurality ofvent holes 221 that extend therethrough. With such a construction, this embodiment has the added advantage of breathability. - Referring to
FIG. 5 , in the third preferred embodiment of an upper according to this invention, the composite material includes afabric layer 31 and an abrasion-resistant coating layer 32. Theshell body 30 further has awaterproof layer 33 overlying an inner surface 312 of thefabric layer 31. Each of thefabric layer 31 and thecoating layer 32 is provided with a plurality ofvent holes vent holes 311 in thefabric layer 31 are registered with thecorresponding vent holes 321 in thecoating layer 32. This embodiment likewise has the advantages of water-resistance and breathability. In addition, as thewaterproof layer 33 is disposed on the inner surface 312 of thefabric layer 31, it is protected from damage. - While the present invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements.
