This application claims priority to PCT Application No. PCT/US1614613 filed on Jan. 22, 2016, which claims priority to U.S. Application, Ser. No. 62/106,522, filed on Jan. 22, 2015, both applications being hereby incorporated by reference for all purposes.
BACKGROUNDThe present disclosure is directed to footwear with interchangeable tops. The top covers can be of different design, styles, materials, as well as color. This allows the wearer to select from or make a wide array of top covers to match to his/her outfit. In particular, this interchangeable top cover, or “upper”, with sole has a locking mechanism that allows for easy switching of the shoe uppers and secure fastening of the shoe uppers to the base, or “sole”.
The present disclosure is directed to footwear with interchangeable tops. The top covers can be of different design, styles, materials, as well as color. This allows the wearer to select from or make a wide array of top covers to match to his/her outfit. In particular, this interchangeable top cover, or “upper”, with sole has a locking mechanism that allows for easy switching of the shoe uppers and secure fastening of the shoe uppers to the base, or “sole”.
Some prior art bearing some relation to the present invention include the following representative references: U.S. Pat. No. 7,877,903 to Barteet, U.S. Pat. No. 8,413,351 to Watters, US 20030233772 to Musial, and US 20110283564 to Stillwagon.
Barteet discloses an interchangeable shoe upper (U.S. Pat. No. 7,877,903). Barteet's design has a limited number, more precisely only four fasteners for each shoe. While a user can change the shoe upper to change the color or pattern of the upper shoe upper and keep or remove the strap, Barteet's design is only used with limited styles of sandal or shoe upper. Further, Barteet's fastener is a snap-receiving fastener where snap-receiving fastener members are attached to the lower surface of the upper member. The upper member can then be attached to the sole and provides a useable shoe. While this configuration of fastener allows a user to easily interchange the shoe upper, but over time, a snap fastening system will loosen and will not securely attach the shoe upper to the sole. This can easily cause the wearer to injure her foot or ankle if the fastener gives way. In addition, the uppers must have snap-receiving fastener members that correspond to the fastening members on the sole, which makes it proprietary in nature.
Watter discusses a system for altering the appearance of a pair of shoes. (U.S. Pat. No. 8,413,351) Watter's design uses the same shoe upper surface and incorporates skins having different designs and a magnetic locking system to change the appearance of the overall shoe. Watter's shoe design includes a plurality of first-half magnets on the base shoe cover and a corresponding plurality of second-half magnets disposed on the interchangeable skins. The first-half magnets are adapted to engage the second-half magnets to help hold the skin in place on the base shoe cover. The cooperating pairs of first and second-half magnets are arranged appropriately such that when the skin is placed over the base shoe cover in the correct position the cooperating first-half and second-half magnets align with each other. While, this design may alter the color and pattern of the shoe cover, this system cannot change the overall style of the shoe because the base shoe cover cannot be easily swapped out.
Musial discloses another interchangeable shoe upper. (US 20030233772) Musial's describes a fastening system located at the front of the shoe that uses hooks and holes/eyelets. This suffers from the disadvantage that it does not maintain the foot securely with the shoe. While Musial mentions other types of fastening systems that can be used such as snaps, laces, hook and pile strips, or zippers, there may be shortcomings with each of these types of fastening systems when used with a shoe with an interchangeable upper. The drawback of repeated use of a snap type fastener has already been mentioned above. A lacing type fastener is advantageous for ease of tightening but can be bulky and have an unpolished appearance. A hook and pile type fastening system also does not afford enough durability when used in a shoe design where there is limited space for an adequate pile strip to receive the corresponding hook strip. Finally, a zipper fastening system has a similar drawback as a lacing system of being bulky and depending on the location of the zipper system, may be difficult to fasten. In addition, the uppers must have receiving fastener members that correspond to the fastening members on the sole, which makes it proprietary in nature.
Stillwagon also discloses an interchangeable shoe upper. (US 20110283564) Similar to other interchangeable shoe upper designs, the invention here discloses only a shoe upper that covers the front of the foot, which limits the number of possible designs and styles that can be created. The fastening system described here is a button type fastener. Unlike a buttoning system on clothing that normally does not come under stress, a buttoning system for a shoe will gradually loosen as the material becomes stretched with use making walking less secure. Once again, the uppers must have receiving fastener members that correspond to the fastening members on the sole, which makes it proprietary in nature.
Thus, with regards to interchangeable shoe upper, there exists a need for a fastening system that can securely hold the shoe upper and can easily be secured and released. The interchangeable shoe system of this present invention uses a fastening mechanism that improves upon mechanisms for interchangeable shoe covering that are already known, and provides for a non-proprietary upper, where the upper simply has holes where the fastener connects to the sole. This present fastening system maintains the shoe upper securely against the sole and allows a user to easily couple and release the shoe upper when user wishes to swap out the shoe upper. Finally, this present system allows for much larger number of style options, since the fasteners are around the entire perimeter of the sole, limited only by the imagination and creativity of the user.
SUMMARYThe present disclosure is directed to a shoe system that is comprised of a sole with a plurality of fasteners disposed about the sole perimeter, the fasteners capable of securing a variety of uppers using only appropriately placed holes in each upper. In some examples, the sole includes sleeves that receive and secure corresponding pins, with the sleeves secured between two layers that create cavities for each sleeve. In other examples, the sleeves are secured within a single molded layer. In some further examples, the sole includes hooks for securing an upper. In still further examples, the sole includes a flange for hiding the fastening mechanism.
The disclosed shoe systems will become better understood through review of the following detailed description in conjunction with the figures. The detailed description and figures provide merely examples of the various inventions described herein. Those skilled in the art will understand that the disclosed examples may be varied, modified, and altered without departing from the scope of the inventions described herein. Many variations are contemplated for different applications and design considerations; however, for the sake of brevity, each and every contemplated variation is not individually described in the following detailed description.
Throughout the following detailed description, examples of various shoe systems are provided. Related features in the examples may be identical, similar, or dissimilar in different examples. For the sake of brevity, related features will not be redundantly explained in each example. Instead, the use of related feature names will cue the reader that the feature with a related feature name may be similar to the related feature in an example explained previously. Features specific to a given example will be described in that particular example. The reader should understand that a given feature need not be the same or similar to the specific portrayal of a related feature in any given figure or example.
The present invention contemplates a system for providing an interchangeable shoe system. Although discussed in relation to a shoe, the present invention readily adapts for use with boots, sandals, and other footwear items. Those having ordinary skill in the art will appreciate the similarities of the present invention regardless if used in conjunction with shoes, boots, sandals, or other footwear items. For ease, the present invention will be discussed in relation to a shoe, but this should not be construed to overly limit the scope and spirit of the present invention.
The shoe system is directed towards a simple-to-use and sturdy fastening system that can easily attach and release a wide variety of shoe uppers to the sole. Here, for simplicity sake, “shoe upper” can also be construed to define shoe top, shoe vamp, and top cover, but this should not be construed to overly limit the scope and spirit of the present invention. This allows a user to quickly and easily change the appearance of the shoe overall by selecting and swapping out a large variety of interchangeable shoe uppers with a single sole. The upper design shown in
The shoe system disclosed within this application has the benefit that the fastening system is not incorporated into the shoe upper as that in the Barteet and Watter disclosures. The current shoe system allows the shoe uppers to be “open source” meaning that anyone can design a shoe upper to be used personally or shared, with the upper simply having holes where the fastener connects to the sole. There would be no proprietary claim on the shoe uppers designed to be used in conjunction with the shoe sole.
The shoe system allows the wearer to have a diverse array of looks to match with different outfits while only having to purchase one pair of shoe soles. The shoe system provides more design options than what is currently available. The shoe system allows a wearer to easily change the shoe uppers without need for specialized tools for interchanging the shoe uppers. While

Shoe Upper
The present invention provides for different shoe upper 101 designs that can couple to the sole though a quick and easy fastening mechanism. The shoe uppers not only have varying designs and styles but may also have different colors as well as being made from different materials that are suitable for shoes such as leathers, other natural fabrics, and any suitable synthetic materials. The fastening system also allows for varying thicknesses of the upper material. It is also the goal of this invention that the user design and create their own shoe upper with different appearances to couple to sole 102, using templates provided or to design their own unique shoe upper design and providing an open source for shoe upper designs that can be shared with the public. Depending on the style of the shoe upper, not all of the fastening points that are spaced along the entire perimeter of the shoe sole will be in use. The fastening points are designed such that they not only have a functional use but add a decorative touch to the overall shoe.
Shoe upper 101 includes one or more apertures 103 along its periphery as shown in
Sole: Overview
With reference to
While at least the fastener top casing 120, fastener bottom casing, and sole 130 are preferably constructed from a durable rubber or similar synthetic material such as viscoelastic polyurethane, a person skilled in the relevant art will recognize that the various components of sole 102 can be constructed from any material now known or later developed that is suitable for the construction of shoes, such as wood, metal, plastic, rubber, leather, composites, or a combination of these materials.
Sole: How the Fastening System is Encased in the Sole
Fastener top casing 120 and fastener bottom casing 122 are in the overall shape of insole 110. On the bottom surface of fastener top casing 120 includes an array of indentations 124 evenly spaced along its periphery. On the top surface of fastener bottom casing 122 are another array of indentations or recesses 126 that correspond to indentations 124. Indentations 124 and recesses 126 are shaped such that when fastener top casing 120 and fastener bottom casing 122 are stacked and permanently coupled, they form an interior space that is able to accept fastener sleeves 150 into these cavities.
The aforementioned preferred rubber-like material of the sole provides a functional aspect to the fastening system. When the interior space is closely sized to the dimensions of the fastening system, the rubber-like material maintains pressure on fastener sleeve 150 such that teeth array 175 of fastening pin 170 remains engaged with slot arrays 162 of fastener sleeve 150. When releasing fastening pin 170, pin head 173 is pushed down, pressing the bottom portion of fastener sleeve 150 into the rubber-like material adjacent to fastener sleeve 150 allowing teeth array 175 to be freed from the corresponding indentations of slot array 162.
In the present embodiment, the top end of sole 102 will include a fastening mechanism within each interior space along its circumference, though not every fastening mechanism will be utilized with any particular shoe upper 101. Finally, it should be noted that all the elements included within the sole of the shoe are permanently bonded such that the only thing that a user could remove are the fastening pins.
Further, sole 102 can be implemented with fastener top casing 120 and fastener bottom casing 122 molded as a single unitary fastener casing, as opposed to two separate parts. In such an implementation, fastener sleeves 150 are preferably placed in predetermined positions in a mold, and the fastener casing is molded around the sleeves 150, thereby permanently encasing them, rather than gluing a top casing 120 and bottom casting 122 together. In further such implementations, shank 112 could also be eliminated, with sole 102 being merged with the unitary fastener casing, resulting in a single one-piece sole with fastener sleeves 150 being molded in place.
Finally, although the preferred fastening mechanism depicted herein is a sleeve and pin, or alternatively, a hook, a person skilled in the relevant art should understand that any fastening mechanism that allows an upper 101 to be secured to the shoe sole 102 without the need for any corresponding hardware in upper 101, apart from a hole for each attachment point, may be utilized. Such mechanisms may include pins, hooks, buttons, snaps, or any other mechanism for secure attachment of material through a hole that resists laterally applied forces as may be experienced by a shoe upper in use.
Fastener Sleeve
Turning to
Long end 151 is substantially a hollow, rectilinear box that includes a generally rectilinear top side 153, a correspondingly rectilinear bottom side 154 disposed opposite to the top side. Top side 153 and bottom side 154 are coupled by a rear side 155 extending generally perpendicular to both top side 153 and bottom side 154. A front side 157 of this box is actually the front end of short end 152. Rear side 155, is best viewed in
As can be seen in
Front side 157 includes an aperture 159. In this embodiment, the free end of front side 157 ends in a hook shaped configuration 158, but in other embodiments, the free end of the front side of the fastener sleeve may include a lip. Aperture 159 has a cross-sectional dimension large enough to accommodate the pin body of fastening pin 170. Further, bottom end of front side 157 is shaped in such a way that it overlaps but does not touch bottom side 154. The distance between the unconnected end of bottom side 154 and the bottom edge of front side 157 corresponds to the amount of allowable upward and downward motion available for bottom side 154 to move.
In other embodiments the fastener sleeve may possess cross-sectional dimensions that are not rectangular, and may be of any shape as long as the interior of the fastener sleeve still contains a means for coupling to and releasing the fastening pin.
Fastening Pin
Fastening pin 170 includes a first end 171 and a second end 172. Disposed on first end 171 is pin head 173. Fastening pin 170 further includes pin body 174. Pin body 174 is configured between pin head 173 and second end 172. In the preferred embodiment, pin body 174 has a largely the same rectangular or round cross-sectional dimension throughout the length of pin body 174 and is able to fit into fastener sleeve 150. Further disposed on the wider of the rectangular surfaces of pin body 174, are corresponding array of teeth 175. Array of teeth 175 in this embodiment are located in the middle of pin body 174. In other embodiments, the arrays of teeth may be on more than one surface of the pin body or covering the entire circumference of the pin body, and may be located on any segment along the pin body. Fastening pin 170 is preferably made from a sturdy material such as plastics or metals or metal alloys. In other embodiments, the fastener sleeve and the fastening pin have cross sectional dimensions that are not rectangular but of any other shape that still allows the fastening pin to fit into and engage with the fastener sleeve and be manufactured from other types of sturdy materials.
In use, either set of teeth array 175 couples to slot array 162 when fastening pin 170 is inserted completely into fastener sleeve 150. Without any external force, bottom side 154 pushes teeth array 175 of fastening pin 170 against the corresponding slot array 162 of fastener sleeve 150. This secures fastening pin 170 within fastener sleeve 150. To release fastening pin 170 from fastener sleeve 150, a user would push pin head 173 of fastening pin 170 to free teeth array 175 from slot array 162 and pull upon pin head 173 to free fastening pin 170 from fastener sleeve 150. This is possible due to the small range of motion of bottom side 154 of fastener sleeve 150.
Fastening pin 170, in conjunction with fastener sleeve 150, comprise means for fastening shoe upper 101 to sole 102. When fastening pin 170 is fully inserted into fastener sleeve 150, there remains a gap 176 between pin head 173 and the outer edges of aperture 159. Gap 176 allows for some flexibility in the thickness of the shoe upper 101 that can be held in place by the fastening system. It will be understood by a person skilled in the relevant art that the thickness of the shoe upper 101 that can be accommodated will depend at least partially on the overall length of fastening pin 170, with longer pins having a greater exposed portion of pin body 174 outside of fastener sleeve 150, thereby accommodating thicker shoe uppers 101. It will also be appreciated that as the length of the exposed pin body 174 increases, it may be necessary to alter the material used to construct fastening pin 170 so as to maintain sufficient rigidity and avoid bending of fastening pin 170 in use. Alternatively, the overall size of fastening pin 170 and corresponding fastener sleeve 150 may be increased to enable longer fastening pins 170 to be used. The fastening system is thereby configured to accept shoe uppers with variable thicknesses.
In some embodiments of the fastener sleeve and the fastening pin, protrusions on corresponding surfaces of the fastener sleeve and the fastening pin may be mated to secure the shoe upper to the sole. In other embodiments, the arrays of teeth or other protruding members may be located elsewhere within the fastener sleeve as long as they correspond to the coupling portion of the fastening pin, allowing the coupling of the fastener sleeve to the fastening pin.
Finally, pin head 173 of fastening pin 170 can be of various designs, color, materials or styles. Thus, not only does the pin head have a functional role but also adds to the overall decorative and stylistic aspects of the shoe sole. A user can have fastening pins with differently designed pin heads that complement the overall look of the shoe. A user may decide to leave open or fill in fastener sleeves with fastening pins that are not in use depending on the preferred look.

Shoe system 200 differs from shoe system 100 in the structure of its sole, a shoe sole 202. Shoe sole 202 includes top fastener cover 220 and a sole 230. Sole 230 further includes a recessed foot bed 203 and a border 204. Top fastener cover 220 can incorporate a midsole and/or shank. Top fastener cover 220 is able to seat within the boundaries of border 204 and couple with recessed foot bed 203. Foot bed 203 includes a series of indentations or cavities 226 along its periphery. Top fastener cover 220 may include a corresponding series of indentations 224 along its periphery. When top fastener cover 220 is mated with sole 230, indentations 224 and cavities 226 form the interior space that is able to accommodate fastener sleeves 250.
Referring to
In both the above-described second and third embodiments, it should be appreciated by a person skilled in the relevant art that, as with the first embodiment, the soles can be alternatively constructed as unified molded single pieces, with the soles being molded around fasteners, as opposed to the assembled sandwich approach detailed above.
Fourth EmbodimentTurning to
Sole 430 includes a top end 431 and a bottom end 432. Situated at top end 431 is a border 433 and a recessed region 434. Border 433 runs along the entire perimeter of sole 430. On the interior face of border 433 are a series of spaced impressions 426. Border 433 defines an open interior space that is able to accept midsole 410. Recessed region 434 is in the shape of midsole 410 and midsole 410 fits within the open interior space defined by border 433, and is permanently adhered to sole 430.
Midsole 410 includes a series of hooks 424 spaced evenly along its periphery. Hook 424 includes an open end 428. A portion of hook 424 is permanently embedded within midsole 410 and secures hook 424 to midsole 410. When hook 424 is coupled to midsole 410, and border 433 is folded down, only open end 428 is exposed. Open end 428 of hook 424 forms the hook. Open end 428 is able to couple to openings on the shoe upper of choice. A user can select from any of hooks 424 to attach a shoe upper 101. Once a shoe upper 101 is secured to midsole 410, a user can fold up border 433 to entirely cover hooks 428. Each hook 424 couples to corresponding impressions 426 and helps secure midsole 410 to sole 430.
As with the previous embodiments, sole 430 can be manufactured from any material or combination of materials that is commonly known and suitable for use in the construction of shoes, but preferably at least the portions of border 433 and recessed region 434 are manufactured from a type of rubber or viscoelastic polyurethane. Because of the rubber-like qualities of at least these portions of sole 430, once midsole 410 is seated with the recessed region 434, midsole 410 remains securely coupled to sole 430. Furthermore, when midsole 410 is permanently mated to sole 430, the fastening mechanism in hidden from view. This provides the appearance of a normal sole couple to a shoe upper where the connection points are concealed. Border 433 material may be the same or different from sole 430. The flexibility in border 433 allows a user to uncouple the upper 401 by flexing back border 433 and releasing hooks 424 from impression 426, then removing the upper 101.
Alternatively, instead of impressions 426, each impression 426 may be carried through border 433 to form holes to allow access to hooks 424 without the need for manipulation of border 433, and the direct attachment of an upper 101. In such an implementation, the exposed portions of hooks 424 can be finished in a decorative fashion, such as in an array of possible colors.
Still further, midsole 410 may be molded as part of lower sole 430, thereby eliminating a border 433 and recessed region 434; in such an implementation, the entire sole is comprised of a single molded piece. Each hook 424 can either be designed to be securely but removably inserted into sole 430 after molding, or sole 430 can be molded around a plurality of hooks 424 that are initially secured into the mold for creating sole 430, thereby securing hooks 424 at the time of manufacture.
Alternative Fastener Arrangement

Sleeve 500 is preferably comprised of a front face 502, an opposing back face 508, and top surface 516 and bottom surface 512 that span between front face 502 and back face 508 so as to comprise a substantially box-shaped configuration. Front face 502 further includes an aperture with a lower aperture portion 504 and an upper aperture portion 506. Back face 508 has a corresponding single opposing aperture 510. Protruding from bottom surface 512 is a ramp 514, and bisecting front face 502 and extending into a portion of both top surface 516 and bottom surface 512 is a slot 518.
Pin 550 includes a head 552, from which protrudes a smaller diameter shaft 554. Into a portion of shaft 554 are machined a series of one or more ridges 556. The diameter of shaft 554 between ridges 556 is smaller than the diameter on ridges 556. Both sleeve 500 and pin 550 are preferably comprised of metal, but may be manufactured from other materials such as plastic or composites, or any other material suitable for manufacturing a durable fastening system that can accommodate the forces imposed by shoe use. At least the head 552 of pin 550 can be decorated in similar fashion to the head 173 of pin 170 as described above.
The shaft 554 of pin 550 is inserted into lower aperture portion 504, and slid through sleeve 500 until it protrudes through opposing aperture 510. Ramp 514 acts to guide shaft 554 to opposing aperture 510 so that it does not get stuck or bound within sleeve 500. Lower aperture portion 504 and opposing aperture 510 are sized to easily accommodate shaft 554. Pin 550 is then secured by applying lateral force to the pin in the direction of top surface 516, causing pin 550 to slip into upper aperture portion 506. It can be observed in the drawings that upper aperture portion 506 is sized smaller than lower aperture portion 504, and as a result two protrusions 505 are created which are spaced smaller than the diameter of pin shaft 554. Slot 518 creates flexibility in the two halves of front face 502, which allow protrusions 505 to widen temporarily to accommodate the passage of shaft 554, and close back down following passage. Shaft 554 is thereby prevented from accidentally slipping from upper aperture portion 506 down to lower aperture portion 504, which could allow pin 550 to inadvertently slip out from sleeve 500 and be lost.
Further, upper aperture portion 506 is preferably sized smaller than the diameter of shaft 554 at each ridge 556, but approximately the diameter of shaft 554 between ridges 556. Thus, when pin shaft 554 is in position 558 within upper aperture portion 506, at least one of ridges 556 engages around the edge of upper aperture portion 506 and is thereby held in place, with longitudinal movement of pin 550 hindered.
Finally, depending on the construction of sleeve 500 and pin 550, ridges 556 may not be necessary. A suitably sized aperture and configured aperture on front face 502 may be capable of retaining a pin 550 with a smooth shaft 554. Still further, it may be possible to integrate the functionality of sleeve 500 into its surrounding fastener casing, or implement sleeve 500 out of a rubber-like material, which is capable of retaining pin 550 merely by friction.
