Description
- Not Applicable
- Not Applicable
- The present invention relates to shoes, more particularly, to open toe shoes with uppers that can be easily replaced.
- Shoes comprise a sole to protect the foot from the ground and uppers to secure the foot to the sole. Often, the appearance of the shoe is paramount. It is generally desirable that the appearance of the shoe coordinate in style and color with the rest of the wearer's clothing.
- The present invention is for use with open toe shoes having a sole of a rigid material and a flexible upper that forms an arch over the front portion.
- The present invention includes methods for removably attaching the upper to the sole. In the first embodiment, the upper is attached to the sole by a set of screws turned into internally-threaded bores in the sole. The bore is a hole formed directly in the sole or the bore is within a hard insert secured in the sole.
- In the second embodiment, the upper is attached to the sole by a set of interference fit studs pushed into bores in the sole. The bore is a hole formed directly in the sole or the bore is within a hard insert secured in the sole.
- The studs are designed to be removable by hand. Several different configurations are contemplated, all of which are designed to compress radially as it is pushed into the bore. The compressed stud pushes against the bore surface to secure the stud in the bore.
- For an upper with a thong, the thong attaches to the foot bed using a threaded rod turned into a threaded bore. The threaded rod may extend from the foot bed or extend from the thong.
- Objects of the present invention will become apparent in light of the following drawings and detailed description of the invention.

FIG. 1 shows one embodiment of theshoe 10 of the present invention. The sole 12 is typically a unitary component with abottom 20, afoot bed 22 on the top, andsides 24 that extend between theback 30 andtoe 32. Thebottom 20 may include aheel 26 or may be flat. Typically, thefoot bed 22 slopes downwardly from theback 30 to thetoe 32. The thickness of the sole 12 determines the height of theshoe 10. - The sole 12 is composed of a rigid material, such as wood, plastic, cork, and/or carbon composite.
- The upper 14 is typically formed from one or more straps of flexible thermoplastic, canvas, twill, leather, or other flexible material. The upper 14 forms an arch over the
front portion 34 of the sole 12 so that theedges 28 of the upper 14 overlap thesides 24 at thefront portion 34. There are many possible shapes for the upper 14, and the present invention contemplates that any shape that can be adapted for the present invention can be used. Some examples ofuppers 14 are shown in the figures. In the example ofFIG. 1 , the upper 14 is aunitary strap 18 a. In the example ofFIG. 2 , the upper 14 is a pair ofstraps 18 b connected by a detachable fastener, such as abuckle 16, as inFIG. 2 , microhook/microloop fastener, snaps, hooks, etc. In the example ofFIG. 3 , the upper 14 is composed ofmultiple straps 18 c that may or may not be attached together. - In the embodiment of
FIG. 1 , the upper 14 is attached to the sole 12 by a set ofscrews 36 turned into internally-threadedbores 38 in the sole 12. - In one configuration, shown in
FIG. 4 , thebore 38 is a hole formed in the sole 12. Depending on the material from which the sole 12 is composed, thebore 38 may or may not be robust enough to not wear out through repeated use. - In another configuration, shown in
FIG. 5 , thebore 38 is in aninsert 48 that is installed in anaperture 40 in the sole 12. Theinsert 48 is composed of a hard material, such as metal or hard plastic, that is resistant to wear. Many different metals, metal alloys, and plastics can be used. By usinginsert 48 made from hard materials, the upper 14 can be replaced a large number of times without the insert's internal threads wearing out. - The size and type of
screws 36 and the size of thebores 38 depend on a number of factors, including, but not limited to, the size and thickness of the sole 12, the thickness of the upper 14 around thehole 42, the number ofscrew 36/bore 38 pairs needed to secure the upper 14 to the sole 12, and the desired style of theshoe 10. The depth of thebore 38 depends on the length of thescrew 36, and will typically be in the range of from ¼-inch to ½-inch deep. - The
screws 36 can be metal or plastic. The desired material is determined by both robustness and style. Metal screws are typically more robust and last longer than plastic screws. On the other hand, plastic screws can be made in any desired color and thescrew head 44 can be made in any desired shape and style. - The upper 14 is attached to the sole 12 by inserting the
screws 36 throughholes 42 in the upper 14 along theedges 28 and turning them into the corresponding threaded bores 38 in the sole 12. The diameter of theholes 42 in the upper 14 is large enough for the threadedportion 46 of thescrew 36 but smaller than the diameter of thescrew head 44. Optionally, theupper holes 42 are reinforced so they do not distort, rip, or otherwise become enlarged such that thescrew head 44 is pulled through thehole 42. - In the embodiment of
FIG. 6 , the upper 14 is attached to the sole 12 by a set of shapedstuds 74 that fit intobores 76 in the sole 12. An interference fit (also known as a press fit or friction fit) retains thestuds 74 in thebore 76. The interference fit is strong enough to hold the upper 14 to the sole 12 under typical conditions but allows thestud 74 to be removed from thebore 76 by hand. - As shown in
FIGS. 7-9 , thebore 76 has a smooth cylindricalinterior surface 92. Optionally, theinterior surface 92 is slightly concave, that is, the center of thebore 76 has a slightly larger diameter than the ends of thebore 76. - In one configuration, shown in
FIG. 7 , thebore 76 is a hole formed directly in the sole 12. Depending on the material from which the sole 12 is composed, thebore 76 may or may not be robust enough to not wear out through repeated use. - In another configuration, shown in
FIGS. 8 and 9 , thebore 76 is in aninsert 94 that is installed in anaperture 96 in the sole 12. Theinsert 94 is composed of a hard material, such as metal or hard plastic, that is resistant to wear. Many different metals, metal alloys, and plastics can be used. By using aninsert 94 made from a hard material, the upper 14 can be replaced a large number of times without thebore 76 wearing out. - Either configuration of the
bore 76 can be used with any configuration of thestud 74. - The
stud 74 is designed to be retained in thebore 76 by friction, thereby providing an interference fit. In general, thestud 74 has abody 88 and ahead 84. Thebody 88 is designed to compress in on itself as it is being installed in thebore 76 and the outward pressure of thebody 88 trying to return to its uncompressed state is what provides the friction against the boreinterior surface 92. - The present invention contemplates several different configurations to provide the compressibility desired.
- In one configuration, shown in
FIG. 7 , thestud body 88 has a taperednose 78 with a diameter that increases to acentral section 80 having a diameter greater than the interior diameter of thebore 76. Alongitudinal slot 82 forms twoparallel legs 86 in thecentral section 80. Thestud 74 is composed of a slightly flexible material that provides the ability to bend as described below. Many different metals, metal alloys, and plastics can be used. - During installation, the
stud 74 is inserted into thebore 76 and pushed. As the stud diameter increases toward thecentral section 80, thecentral section 80 pushes against theinterior surface 92 of thebore 76. As thestud 74 pushes farther into thebore 76, theslot 82 provides a gap into which the twolegs 86 of thecentral section 80 can bend. Bending thelegs 86 inwardly causes them to press outwardly against theinterior surface 92 of thebore 76, thereby securing thestud 74 in thebore 76 by friction. - In another configuration, shown in
FIG. 8 , thestud body 88 has a taperednose 102 and a plurality ofribs 104. The diameter of theribs 104 is greater than the interior diameter of thebore 76. Alongitudinal slit 106 that runs from thenose 102 almost to thehead 84 forms twoparallel legs 108. Thestud 74 is composed of a slightly flexible material that provides the ability to bend as described below. Many different metals, metal alloys, and plastics can be used. - During installation, the
stud 74 is inserted into thebore 76 and pushed. As thestud 74 enters thebore 76, theslit 106 provides a gap into which the twolegs 108 can bend. Bending thelegs 108 inwardly causes them to press outwardly against theinterior surface 92 of thebore 76, thereby securing thestud 74 in thebore 76 by friction. - In another configuration, shown in
FIG. 9 , thestud body 88 is composed of a hard material, such as metal or plastic, that is covered by asleeve 112 composed of silicone or other pliable material. The diameter of thestud body 88 is larger than that of thebore 76. During installation, thesleeve 112 compresses when pressed into thebore 76 and pushes against theinterior surface 92 of thebore 76 to secure thestud 74 in thebore 76. - In another configuration, the
stud body 88 is composed of a slightly resilient material with a diameter that is larger than that of thebore 76. During installation, thestud body 88 compresses when pressed into thebore 76 and pushes against theinterior surface 92 of thebore 76 to secure thestud 74 in thebore 76. - The upper 14 is attached to the sole 12 by inserting the
studs 74 through theholes 42 in the upper 14 along theedges 28 and pushing them into thecorresponding bore 76 in the sole 12. The diameter of theholes 42 in the upper 14 is large enough for thebody 88 of thestud 74 but smaller than the diameter of thestud head 84. Thestud 74 is pushed into thebore 76 until thehead 84 holds the upper 14 against the sole 12. Optionally, theupper holes 42 are reinforced so they do not distort, rip, or otherwise become enlarged such that thestud head 84 is pulled through thehole 42. - The
studs 74 are removed manually either by prying out with fingers or by using an optional tool that resembles a two-tined fork. The tines slide between thehead 84 and upper 14 or between the upper 14 and the sole 12 to pull thestud 74 from thebore 76. - The size of the
studs 74 and thebores 76 depends on a number of factors, including, but not limited to, the size and thickness of the sole 12, the thickness of the upper 14 around thehole 42, the number ofstud 74/bore 76 pairs needed to secure the upper 14 to the sole 12, the material from which thestud 74 is made, and the desired style of theshoe 10. The depth of thebore 76 depends on the length of thestud 74, and will typically be in the range of from ½ inch to 1½ inches. - When used, the
inserts apertures sides 24 of the sole 12 and are secured in theapertures insert aperture insert aperture - In one method of securing the
insert aperture insert aperture insert aperture insert insert aperture - In another method of securement, an adhesive is used to secure the
insert aperture insert insert aperture - In another method of securement, the outer surface of the
insert insert aperture insert - In another method of securement, the
insert composite soles 12. The outer surface of theinsert insert - The
bores shoe 10.FIG. 1 shows fourbores 38 on eachside 24 of the sole 12. - The present invention contemplates that not all of the
bores FIG. 1 , there may be more than fourbores 38 on eachside 24, but because the upper 14 only has fourholes 42 on each side, not all of thebores 38 are needed. - The present invention can also be used with
uppers 14 that have athong 52, as inFIGS. 10 and 11 . Thethong 52 attaches to thefoot bed 22 by a threaded attachment, of which several non-exclusive embodiments are envisioned. - In one embodiment, shown in
FIG. 10 , there is a threadedbore 54 in thefoot bed 22 of the sole 12 and a mating threadedshank 56 at the end of thethong 52. The threadedshank 56 is turned into thebore 54 prior to thescrews 36/studs 74 being installed. Optionally, in order to reduce wear, thebore 54 is within an insert within an aperture, as described above. - In another embodiment, shown in
FIG. 11 , a threadedrod 58 extends upwardly from thefoot bed 22 and a mating threadedaperture 60 is at the end of thethong 52. The threadedrod 58 can be attached to thefoot bed 22 in any number of different ways. InFIG. 11 , the sole 12 has abase 64 and acover 66 made from, for example, leather. Therod 58 is attached to adisk 68 and thedisk 68 is attached to thebase 64. Thecover 66 has ahole 70 through which therod 58 extends. Therod 58 is placed through thehole 70 and thecover 66 is adhered to thebase 64, thereby covering and securing thedisk 68 to the sole 12. - If the sole 12 is thick enough, the
rod 58 can be threaded directly into the sole 12 or therod 58 can be threaded into an insert secured in the sole 12. Alternatively, therod 58 can be glued into an aperture in the sole 12. - The
aperture 60 is within aninsert 62 within thethong 52. As with the inserts described above, thethong insert 62 is composed of a hard material, such as metal or hard plastic, that is resistant to wear. - Thus it has been shown and described a shoe with a replaceable upper. Since certain changes may be made in the present disclosure without departing from the scope of the present invention, it is intended that all matter described in the foregoing specification and shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense.
