    专利说明:
    [0001] 1. Field of the Invention [0001]
    [0002] This invention relates broadly to the field of footwear formed of a molded shell comprising an upper and insole. More particularly, this invention relates to such footwear in which the molded shell includes a molded web platform thereon for securing the outsole. [0002]
    [0003] 2. State of the Art [0003]
    [0004] Footwear comprising a molded upper formed of material such as thermoplastic urethane has several advantages over footwear comprising a rubber upper. Such molded uppers are, for example, more abrasion resistant than rubber uppers. Molded uppers are also more uniform in appearance than rubber uppers because they do not vary in texture or color as do rubber uppers. [0004]
    [0005] There are, however, certain shortcomings associated with footwear having molded shells. For example, the insole portion of the molded shell must often have a matching configuration to the outsole to which it is cemented in order to provide a close fit between the insole and the outsole. Because the insole may have a unique configuration, it is necessary that the outsole have a matching unique configuration. This means that if a variety of insoles are being produced, an equal variety of outsoles must be maintained. Furthermore, should it be desired to replace a worn outsole, it would be necessary to use a replacement outsole having a configuration that matches the insole. Here again, it would be necessary to maintain a wide variety of outsoles for replacement purposes. It would therefore be desirable to provide footwear having a molded shell which does not require an outsole of a particular matching configuration, either for original production or replacement. [0005]
    [0006] Footwear having molded shells are often designed to be of waterproof construction. When, however, such a shell is secured to the outsole by stitching through the shell, the stitches may create holes in the shell through which water may seep. It would therefore be desirable to provide footwear having a molded shell which is secured to the outsole by stitching but which would not have holes in the shell through which water may enter and contact the wearer's foot. It would also desirable to provide footwear formed of a molded upper and an outsole in which a stitched web portion creates a fashionable European-style appearance. [0006] SUMMARY OF THE INVENTION
    [0007] It is therefore an object of the invention to provide footwear having a molded shell comprising an insole which does not require an outsole of the same configuration as the insole. [0007]
    [0008] It is another object of the invention to provide footwear having a molded shell comprising an insole having a web portion which is stitched to the outsole, and wherein the shell does not include holes through which water may enter and contact the wearer. [0008]
    [0009] It is a still further object of the invention to provide footwear having a molded shell comprising an insole having a web portion which is stitched to the outsole to create footwear of a fashionable European-style appearance. [0009]
    [0010] In accordance with these objects, the footwear of the present invention has a molded shell, the bottom portion of which is an insole, and an integrally molded web platform around the periphery of the bottom portion. The outsole is first cemented to the bottom of the insole and to the bottom of the web platform and then the web platform is stitched to the outsole. With the provided arrangement, it is not necessary that the insole and the outsole have the same configuration since the stitching securing the web platform to the outsole conceals any spacing that may occur because the inner sole and outsole are not of matching configurations. The stitching also prevents separation of the inner and outsole soles. It is therefore unnecessary to maintain a wide variety of outsoles for the production or repair of the footwear. In addition, since it is the web platform which is stitched to the outsole and not the portion of the shell which surrounds the foot, any holes created by the stitching will occur in the web platform and not in the shell. Thus, there are no openings in the shell through which water may seep. Further, an aesthetically pleasing molded footwear having a stitched web portion is provided. [0010]
    [0011] Additional objects and advantages of the invention will become apparent to those skilled in the art upon reference to the detailed description taken in conjunction with the provided figures. [0011] BRIEF DESCRIPTION OF THE DRAWINGS
    [0012] FIG. 1 is a side elevational view of the molded shell comprising a web portion of the present invention; [0012]
    [0013] FIG. 2 is a plan view of the web portion and the bottom of the molded shell which forms the insole; and [0013]
    [0014] FIG. 3 is a side elevational view of a boot formed of the molded shell comprising a web portion shown in FIG. 1. [0014] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
    [0015] There is shown in FIGS. 1 and 2 a molded shell [0015] 2 formed from suitable material such as thermoplastic urethane by a conventional molding process. Shell 2 comprises an upper 4 and contiguous bottom portion 6, which serves as an insole for fully enveloping the wearer's foot. Upper 4 includes eyelets 5 for lacing 7. Shell 2 may include various embossed aesthetic designs 8. An integral web portion 10 is molded on shell 2 and extends around the periphery of shell 2 at the bottom portion thereof. Although shell 2 is shown as an upper for a boot, the present invention may also be used for a shoe. Web portion 10 includes spaced indentations 12 throughout the top portions thereof for aesthetic purposes. An outsole 15 having treads 14 thereon includes a heel portion 16. The outsole may be formed of rubber such as sold by Quabaug corporation under the registered trademark “Vibram”.
    [0016] To produce the footwear of the present invention, the bottom of web portion [0016] 10 and the bottom of insole 6 are cemented to the top of outsole 14 in conventional manner. The web portion 10 is then stitched to the outsole 14 by stitches 16 (see FIG. 2). The stitching may, for example, be of the type known as Goodyear stitching, and the width of the stitches 16 may be approximately six per inch. In this manner, the shell 2 and the integral web portion 10 thereon are firmly secured to the outsole 14.
    [0017] There has been described and illustrated herein footwear comprising a molded shell for fully enveloping the wearer's foot and wherein an integral web portion is molded with the shell. The bottom of the shell and the web portion is cemented to the outsole and then the web portion is stitched to the outsole. While a particular embodiment of the invention has been described, it is not intended that the invention be limited thereto, as it is intended that the invention be as broad in scope as the art will allow and that the specification be read likewise. It will therefore be appreciated by those skilled in the art that modifications could be made to the provided invention without deviating from its spirit and scope as claimed. [0017]
