## Background
CROSS REFERENCE TO RELATED APPLICATION
This application is a continuation-in-part of application Ser. No. 10/263,179, filed on Oct. 3, 2002 the contents of which is herein incorporated by reference.


FIELD OF THE INVENTION
The invention generally relates to footwear, particularly to a shoe having interchangeable components and most particularly to a shoe having a conveniently detachable upper referred to herein as a vamp such that said vamp can be releaseably attached to the periphery of a sole member.
BACKGROUND OF THE INVENTION
Although the basic function of footwear is protection of a person's feet, shoes are most often viewed and purchased only with regard to fashion. For example, a person selects a particular pair of shoes to enhance and/or complement clothing worn and when the person changes clothing, since a single color and/or style of shoes will not match all colors and/or styles of clothing he/she, more often than not, must select another pair of shoes, Thus, in order to be fashionably dressed, a person must own many pairs of shoes.
Unfortunately, owning multiple pairs of shoes can be very expensive in terms of both cost and storage space. Footwear that is compatible with many styles of clothing would alleviate these disadvantages by reducing the number of pairs of shoes a person must own, thereby also freeing up storage space. An example of such footwear is shoes having interchangeable components including interchangeable upper referred to as vamps.
While other shoes systems have existed incorporating detachable vamps, none of the prior art provide an interchangeable vamp that is well suited when the vamp is made of relatively soft or flexible materials including, by way of example only, neoprene, rubber or other polymer materials. While such materials are particularly useful in that they are comfortable, relatively inexpensive to manufacture, capable of easy decoration by various techniques including but not limited to silkscreening and thereby capable of taking on a wide variety of styles and appearances, and, further, are interchangeable across a variety of differently sized base members, they suffer from the drawback that when affixed by means of mechanical snaps, hook-and-loop systems or otherwise similar fasteners, the lower edge of the vamp tends to gather, bunch or pull out of alignment with the edge of the base member. In other words, the edge of the vamp does not remain in a line with the peripheral edge of the base member and therefore the aesthetic appearance of the shoe is compromised.
Previous attempts to resolve this issue have failed as the need to utilize an edging having appropriate characteristics has heretofore been unknown in the art. Thus where satin finished webbing material such as the Black Polypropelene Material, Part #N00881 1′′, manufactured by the Steed Co. has been employed, the edging fails to ameliorate or prevent the tendency of the vamp to gather, bunch or pull out of alignment.
The edging must therefore be of a certain stiffness and rigidity capable of adequately securing the vamp to the base while preventing the unsightly tendency of the vamp to be pulled out of alignment. The edging, furthermore, when the same or similar color as the base member, may also serve the further aesthetic purpose of producing the appearance of a seamless transition between vamp and base member. Alternatively the edging may be of a color to accent or otherwise improve the aesthetic appearance of the shoe. Accordingly, it would be desirable to provide a shoe having an interchangeable vamp which is readily affixed in a secure manner to the base member without compromising the aesthetic appeal of the shoe.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the present invention to provide for a vamp for use in conjunction with an interchangeable shoe assembly that remains readily affixed to the base of the shoe while avoiding the unsightly tendency of the vamp to bunch or gather or otherwise to pull out of alignment where the vamp attaches to the base member.
Further objectives of the invention claimed herein are to provide added strength to the vamp which may have a tendency to wear out as the vamps are interchanged by the wearer. Additionally, the edging may carry out the aesthetic function of serving to mask the transition between vamp and shoe base or alternatively to provide a decorative accent.
Other objectives and advantages of the instant invention will become apparent from the following description taken in conjunction with the accompanying drawings wherein are set forth, by way of illustration and example, certain embodiments of the instant invention. The drawings constitute a part of this specification and include exemplary embodiments of the present invention and illustrate various objects and features thereof.



BRIEF DESCRIPTION OF THE FIGURES
FIG. 1 is a side view of an interchangeable shoe assembly with a vamp bound by edging affixed to the base member of the shoe by means of fasteners, here mechanical snaps.
FIG. 2 is a top view of a vamp bound by edging according to the present invention.
FIG. 3 is a bottom view of a vamp bound by edging according to the present invention.



The preferred embodiments of the instant invention will hereinafter be described in conjunction with the appended drawings provided to illustrate and not to limit the invention, and in which:
DETAILED DESCRIPTION OF THE INVENTION
For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same. However, the illustrated embodiments are merely exemplary. It is understood that no limitation of the scope of the invention is thereby intended. Any alterations and further modifications in the illustrated devices, and such further application of the principles of the invention as illustrated herein are contemplated as would normally occur to one skilled in the art to which the invention relates.
Shown throughout the figures, the instant invention is generally directed to footwear, particularly shoes and sandals having a simple, convenient fastening system capable of releasably attaching a vamp to a shoe sole, wherein the vamp is bound by an edging that allows a couplable detachment while preventing or ameliorating the unsightly tendency of the shoe to bunch or gather or otherwise pull out of alignment with the base member.
An embodiment of the vamp, as part of an shoe-forming assembly, is illustrated in FIG. 1. This footwear is preferably in the form of a shoe or sandal and generally includes a sole or shoe base member, 1, a vamp or upper member, 2, and fastening members, for example, snap fasteners 3, and 4. The vamp member may be fabricated of polymer compositions or other synthetic or non-synthetic rubber materials such as neoprene. Various other, natural materials may also be used to fabricate vamps including leather, canvas or other cloths. In any situation where the vamp is made of relatively soft or flexible materials, peripheral edges of the vamp may be bound to address the concerns discussed above and herein.
As shown in FIG. 1, the fasteners, here mechanical snaps 3 and 4, are disposed laterally along the edge of the base member, 1. Where no edging is used, or insufficiently strong or stiff material is used to edge the vamp, 2, the vamp tends to gather and bunch at the fasteners, 3 and 4. This compromises the aesthetic, and therefore commercial, appeal of the shoe. The vamp also has a tendency to pull out of alignment with the base member, 1, and the fasteners, 3 and 4. When bound by edging, 5, with appropriate characteristics, however, the problems identified above are either prevented or ameliorated.
FIG. 2 shows a top view of the upper portion, 21, of a trapezoidal-shaped vamp 20. The peripheral sides, left 22 and right 23, of the vamp, 1, are bound by edging 24 and 25. The edging, 24 and 25, consists of an elongated, rectangular strip of material having appropriate characteristics of strength and stiffness, and folded through the center, at the respective edges, 22 and 23, of the vamp and is bound to and covers the right, 22 and left, 23, peripheral sides of vamp member, 20. The edging generally covers (but is not limited to) about a half inch of the upper and lower surfaces of the vamp, i.e. edging 24 and 25 cover the upper surface of the, respectively left and right peripheral edge. The edging may be attached to the vamp by any suitable method, including, but not limited to gluing or stitching.
FIG. 3 shows a bottom view of the lower portion, 30, of a trapezoidal-shaped vamp 20 having edging, 34 and 35, that covers lower surface 33 of the vamp at the peripheral edges, 32 and 33. The edging, 5, 24, 25, 34 and 35, (FIGS. 1, 2 and 3), is of a strength and stiffness such that the edging holds the left and right peripheral edges, 21, 22, 32 and 33 of the vamp in line with the fasteners at 26, 27, 28 and 29, and further prevents the vamp from bunching and gathering at those points. The addition of edging, 5, 24, 25, 34 and 35, further strengthens the fasteners such that the vamp portion can withstand repeated release and exchange without breaking and/or wearing out. The edging, 5, 24, 25, 34 and 35 is preferably constructed from, but is not limited to, a nylon material. An example of such a material is the Nylon Heatset N0023S-1 manufactured by Tape Craft, Inc. That particular nylon webbing is a blend of three types of nylon yarn, i.e. 840 denier type 6 gauge thread, 420 denier type 6 gauge and 210 type 66 gauge yarn. The material is solution dyed and a medium heat set is applied to provide a medium “starch” to the material. Further the binders and stuffing used in the webbing are all nylon materials. The webbing is 1′′ in width and 0.034′′ in thickness and further possesses a tensile strength of 1350 LBF. Materials possessing characteristics similar in respect to strength and stiffness as the Nylon Heatset N0023S-1 are flexible enough for use to edge vamps in the instant system yet strong and stiff enough to prevent the tendency of the material to gather, bunch or pull out of alignment with the peripheral edge of the base member. Whatever material is used, the material must be of a strength and stiffness to avoid the problems identified above, i.e bunching, gathering and pulling out of line (in the area wherein the fasteners are attached).
