Description
- 1. Field of the Invention
- The invention relates to a shoe, more particularly to a shoe having an upper made of a flat composite and a method of making the shoe.
- 2. Description of the Related Art
- Referring to
FIG. 1 , a conventional shoe includes asole unit 3, an upper with a three-dimensional moldedlower portion 2, and an upper portion 1. A lower end of the upper portion 1 is stitched to an upper end of thelower portion 2. A lower end of thelower portion 2 is adhered to thesole unit 3. Thelower portion 2 is integrally molded, and is generally formed from rubber, thermoplastic polyurethane (TPU), thermoplastic rubber (TPR), etc. Therefore, thelower portion 2 can afford good supportability, protection, and water-resistance, and is adaptable for use in hunting boots, security shoes, hiking shoes, pac boots. However, in actual manufacture and application, thelower portion 2 suffers from the following drawbacks: - 1. The fabrication of the
lower portion 2 requires use of a three-dimensional mold in order to match the shape of the foot. Such three-dimensional molds are not easy to manufacture, and the costs thereof are very expensive, thereby resulting in increased fabrication costs. - 2. Since the
lower portion 2 is molded, the shape and dimensions thereof are substantially fixed and cannot be adjusted. Therefore, manufacturers have to fabricatelower portions 2 of different dimensions using different molds so as to adapt to lasts of different specifications. This results in increased fabrication costs. - 3. Likewise, the
lower portion 2 is applicable only to a particular shoe-making process, and is not suitable for other processes, such as hand-sewing, lasting, etc. - 4. It is difficult to secure a fabric layer to the inner side of the three-dimensional
lower portion 2 during the molding process. Thus, the fabric layer is adhered to the inner side of thelower portion 2 after thelower portion 2 is formed. - 5. As the
lower portion 2 is integrally molded and is formed from air-impermeable rubber or plastic material, thelower portion 2 is not breathable, thereby resulting in discomfort to the wearer. - 6. In order to provide the
lower portion 2 with a predetermined degree of strength, thelower portion 2 is configured to have a large thickness, which not only increases the weight of the shoe but also affects the bendability of the shoe, especially at the toe region when the wearer squats. - In addition, while it is known in the art to use laminate material in the manufacture of shoe parts, the prior art does not emphasize that the forming of air vents in a thermoplastic material during the molding process, nor the forming of air vents in the thermoplastic material prior to formation of the laminates.
- Therefore, the object of the present invention is to provide a shoe having a lower portion of an upper which is made from a flat composite and which can be produced easily at low costs.
- According to one aspect of the present invention, the shoe of this invention includes an upper made of a flat composite which includes a substantially flat molded plastic layer and a fabric layer adhered to an inner side of the molded plastic layer. The plastic layer has an inner peripheral end defining an opening, an outer peripheral end extending around the inner peripheral end, and two opposite marginal ends each extending from the inner peripheral end to the outer peripheral end. Both of the inner and outer peripheral ends are terminated at the marginal ends. The flat composite is looped and formed into the upper when the marginal ends are connected to each other. The fabric layer further has an extension flap that extends beyond the outer peripheral end and between the marginal ends and that is formed as one piece with the fabric layer.
- Advantageously, the plastic layer may be further provided with at least one molded ventilation hole, wherein the fabric layer covers the ventilation hole.
- According to another aspect of the present invention, a method of making a shoe comprises molding a substantially flat plastic layer directly over a fabric layer to form a flat composite, the plastic layer being formed with at least one ventilation hole, two opposite marginal ends, and inner and outer peripheral ends interconnecting the marginal ends, the inner peripheral end defining an opening, the outer peripheral end extending around the inner peripheral end. The method further includes: providing the fabric layer with an extension flap that extends beyond the outer peripheral end and between the two marginal ends and that is formed as one piece with the fabric layer; and interconnecting the marginal ends so that the flat composite is looped and formed into at least a portion of an upper.
- 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 side view of a conventional shoe having an upper with a molded lower portion; -
FIG. 2 is a side view of the first preferred embodiment of a shoe according to the invention; -
FIG. 3 is a schematic sectional view of the first preferred embodiment; -
FIG. 4 is a schematic rear sectional view of the first preferred embodiment; -
FIG. 5 is a schematic plan view of a flat composite used to form a lower portion of an upper in the first preferred embodiment; -
FIG. 5A shows how the flat composite is made; -
FIG. 6 is similar toFIG. 5 , but showing the flat composite in a trimmed state; and -
FIG. 7 is a perspective view of the flat composite ofFIG. 6 which is looped to form the lower portion of the upper. - Referring to
FIGS. 2, 3 and 4, a preferred embodiment of a shoe according to the present invention is shown to include an upper (A) and asole unit 30. - The upper (A) includes a
lower portion 20 and anupper portion 10. Thelower portion 20 has anopen bottom end 24 connected to thesole unit 30, and anopen top end 23 connected to anopen bottom end 12 of theupper portion 10. Thelower portion 20 has atoe region 26, twoshank regions 28 extending rearwardly from thetoe region 26, and aheel region 27 connected to theshank regions 28. - Referring further to
FIGS. 5 and 6 , thelower portion 20 is made of aflat composite 100 which includes a substantially flat moldedplastic layer 120, and afabric layer 110 bonded to an inner side of theplastic layer 120. A breathablewaterproof layer 130 is attached to an inner side of theflat composite 100. Theflat composite 100 is looped and formed into a three dimensional shape to provide thelower portion 20. In addition, theplastic layer 120 has an innerperipheral end 121 defining anopening 122, an outerperipheral end 123 extending around the innerperipheral end 121, two oppositemarginal ends 25 each extending from the innerperipheral end 121 to the outerperipheral end 123. Thus, the inner and outerperipheral ends marginal ends 25, and both of the inner and outerperipheral ends marginal ends 25. Theflat composite 100 is looped and formed into thelower portion 20, as shown inFIG. 7 , when themarginal ends 25 are connected to each other in theheel region 27. Preferably, themarginal ends 25 are interconnected by sewing. Aconnection plate 40 is secured to theflat composite 100 in theheel region 27 by sewing to cover themarginal ends 25. - While the
marginal ends 25 are interconnected in theheel region 27 in this embodiment, themarginal ends 25 may also be interconnected in thetoe region 26 or one or two of theshank regions 28 according to the present invention. - The
plastic layer 120 may be made of any suitable plastic material. Preferably, theplastic layer 120 includes a thermoplastic material selected from a group consisting of thermoplastic polyurethane (TPU), thermoplastic rubber (TPR) and polyvinylchloride (PVC). Theplastic layer 120 may be molded in a mold (not shown) to form the inner and outer peripheral ends 121, 123 and the marginal ends 25. An outer patterned surface and a plurality ofventilation holes 211 are also formed in theplastic layer 120 during the molding of theplastic layer 120. - The
fabric layer 110 is bonded to theplastic layer 120, and may be made from a fabric subjected to an anti-splash treatment. The anti-splash treatment may be conducted after being bonded to theplastic layer 120. Preferably, theplastic layer 120 is bonded to thefabric layer 110 by molding it directly over thefabric layer 110 in a mold (seeFIG. 5A ). The direct molding of theplastic layer 120 may be done by placing thefabric layer 110 in a mold followed by the introduction of a thermoplastic material into the mold. After thefabric layer 110 is bonded to theplastic layer 120, thefabric layer 110 is trimmed relative to the inner and outer peripheral ends 121, 123, and the marginal ends 25 of theplastic layer 120. Thefabric layer 110, therefore, has a profile substantially corresponding to that of the innerperipheral end 121 and the marginal ends 25. However, thefabric layer 110 is provided with anextension flap 111 that extends beyond the outerperipheral end 123 and between the twomarginal ends 25 of theplastic layer 120. Particularly, theextension flap 111 is formed as one piece with thefabric layer 110. To enhance the bonding between theplastic layer 120 and thefabric layer 110, a reinforcingstitch line 29 may be provided along the outerperipheral end 123 of theplastic layer 120 to sew thefabric layer 110 to theplastic layer 120, as best shown inFIG. 6 . - The breathable
waterproof layer 130 is attached to thefabric layer 110 opposite to theplastic layer 120. The breathablewaterproof layer 130 may be sewn to thebottom end 12 of theupper portion 10 and the opentop end 23 of thelower portion 20, and awaterproof strip 293 may be bonded to an inner side of thelower portion 20 and the breathablewaterproof layer 130 along the opentop end 23. Alternatively, the breathablewaterproof layer 130 may be bonded to thefabric layer 110 before the latter is bonded to theplastic layer 120. Certainly, the breathablewaterproof layer 130 may also be bonded directly to thefabric layer 110 after the latter is bonded to theplastic layer 120. - The
sole unit 30 in this embodiment includes theinsole 31 and anoutsole 32 with atread plate 321. The openbottom end 24 of thelower portion 20 is lasted to a bottom side of theinsole 31. Theoutsole 32 is attached to thebottom end 24 of thelower portion 20. - The
extension flap 111 which extends beyond the outerperipheral end 123 of theplastic layer 120 provides flexibility to facilitate folding of thebottom end 24 of thelower portion 20 and a greater bonding area for a bonding connection between thebottom end 24 and the bottom side of theinsole 31. In addition, when thelower portion 20 is mounted on a last (not shown) for lasting thelower portion 20 over theinsole 31, a pulling force may be applied conveniently to theextension flap 111 to pull thebottom end 24 of thelower portion 20. The lasting operation can therefore be facilitated. While theflat composite 100 is illustrated as being used in a lasted shoe, theflat composite 100 may also be used in other shoe constructions, such as, hand stitched shoes. - A preferred embodiment of a process for making the shoe of this preferred embodiment will be described in the following paragraphs:
- Referring to
FIGS. 5 and 5 A, theflat composite 100 is prepared by placing thefabric layer 110 between upper andlower mold parts plastic layer 120 directly over thefabric layer 110. Theplastic layer 120 is therefore adhered to thefabric layer 110 by an adhesion of theplastic layer 120 per se. The ventilation holes 211 are formed during molding and are covered by thefabric layer 110 which is ventilative. No cementing material, such as an adhesive which can block the ventilation holes 211, is provided between theplastic layer 120 and thefabric layer 110 in this embodiment. However, if a cementing material between theplastic layer 120 and thefabric layer 110 is desired, the cementing material should not be provided in a region where the ventilation holes 211 are formed. - Referring once again to
FIGS. 5 and 6 , thefabric layer 110 is trimmed relative to the inner and outer peripheral ends 121, 123 and the marginal ends 25 of theplastic layer 120 after molding so as to have a profile substantially corresponding to that of theplastic layer 120. - Referring once again to
FIGS. 3 and 7 , two opposite marginal ends 25 of theplastic layer 120 are sewn together such that theflat composite 100 is looped and formed into thelower portion 20. Theconnection plate 40 is then secured to theflat composite 100 such as by sewing. - Referring once again to
FIG. 3 , thebottom end 12 of theupper portion 10 is sewn to thetop end 23 of thelower portion 20, thereby forming the upper (A). - Referring further to
FIG. 3 , thebottom end 24 of thelower portion 20 is connected to aninsole 31, and theoutsole 32 is connected to thebottom end 24 of thelower portion 20. The connection between theinsole 31 and thelower portion 20 is accomplished by a conventional lasting process. Afiller 33 is disposed between theinsole 31 and theoutsole 32. - Alternatively, a hemming fabric strip may be provided along the outer
peripheral end 123 to enclose the outerperipheral end 123 and an end of thefabric layer 110 bonded to the outer peripheral end. This arrangement prevents peeling of thefabric layer 110 from theplastic layer 120 during the lasting operation. - The shoe of the present invention thus formed has the following advantages:
- 1. Since the
lower portion 20 is formed to have an rudimentary three-dimensional shape by sewing the marginal ends 25 of theplastic layer 120 to loop theflat composite 100, the need to use a conventional complicated and expensive three-dimensional mold may be eliminated. - 2. Since the
lower portion 20 is made from theflat composite 100, thelower portion 20 is more flexible to adjust or change its dimensions compared to the molded lower portion of the conventional upper. Thus, the cost of mold-making for the process can be reduced. - 3. The
lower portion 20 is suitable for various shoe-making processes, such as lasting, hand stitching. - 4. The
fabric layer 110 bonded to theplastic layer 120 can serve as a lining for thelower portion 20. Such a lining can be prepared more easily compared to a conventional lining which is attached to an inner surface of the conventional molded lower shell of an upper. - 5. The
fabric layer 110 bonded to theplastic layer 120 is breathable and can serve as a protection screen to block entry of particles into the shoe through the ventilation holes 211. Thus, the present invention eliminates the need to provide an additional screen member which is required in a conventional ventilated shoe. On the other hand, although thelower portion 20 is provided withventilation holes 211, due to the presence of the breathablewaterproof layer 130 at the inner side of thelower portion 20, thelower portion 20 which is made of theflat composite 100 is not only breathable but also waterproof. - 7. The
fabric layer 110 reinforces theplastic layer 120 so that the thickness and weight of theplastic layer 120 may be reduced. - In sum, the shoe of this invention provides the advantages, such as, reduced mold cost, light weight, good bendability and good breathability, and can accommodate different sizes of lasts and different shoe constructions.
