Athletic Shoe Protector

Abstract

A shoe has an upper portion with an outer surface, a sole and a closure. A heat shrinkable plastic material is formed into a shoe cover that defines a recess complementary in shape to an upper portion of the shoe. The shoe cover defines a bottom opening having dimensions so as to expose the sole of the shoe when the shoe is placed within the recess. The shoe cover also defines a top opening having dimensions so as expose the closure while still covering the substantially all of the upper portion except for the closure. The heat shrinkable plastic material includes a material that causes the shoe cover to shrink to the outer surface of the shoe when subjected to heat at a predetermined temperature.

DETAILED DESCRIPTION OF THE INVENTION

[0044] A preferred embodiment of the invention is now described in detail. Referring to the drawings, like numbers indicate like parts throughout the views. Unless otherwise specifically indicated in the disclosure that follows, the drawings are not necessarily drawn to scale. As used in the description herein and throughout the claims, the following terms take the meanings explicitly associated herein, unless the context clearly dictates otherwise: the meaning of a, an, and the includes plural reference, the meaning of in includes in and on.

[0045] As shown in FIGS. 1-2, one representative embodiment of a shoe cover 10 can, for example, be used with an athletic shoe such as a soccer boot with cleats. (It can also be used with other types of shoes, including work boots, business shoes, etc.) It reinforces the shoe upper and protects the upper from scuffing and moisture. The shoe cover extends around the seam between the upper and the soul of the shoe and covers a portion of the outsole leaving the cleats exposed. The shoe cover is made of a heat shrinkable material with a heat activated adhesive. The shoe cover is first preformed into a shoe-shaped blank that is fitted over the shoe and then is heated to further conform the shoe cover to the shoe and to activate the adhesive.

[0046] An athletic shoe cover 10 applied to a shoe is shown in FIGS. 1-2, 10-15, and 21-26. FIGS. 3-9 and 16-20 show the shoe cover 10 of the present invention as a preformed shoe cover blank 20.

[0047] The material that is suitable for the shoe cover of the present invention should be relatively thin (10 mil-30 mil thick and 10 mil-20 mil thick in one commercial embodiment) and be able to shrink to the complex contours of modern day athletic shoes or soccer boots. The material should also be shrinkable at low temperature. Such materials include low temperature shrinkable thermoplastic/elastomeric/polyolefin such as cross-linked polyolefin sheet material with a low recovery temperature of 50 C.65 C. Such materials include, without limit, ethylene vinyl acetate (EVA), fluorinated ethylene propylene (FEP), perfluoroalkoxy alkane (PFA), polytetrafluoroethylene (PTFE), polyethylene (PE), polypropylene (PP), or polyethylene terephthalate (PET). Alternatively, a cold shrink rubber such as neoprene rubber (NR), nitrile rubber (NBR), and ethylene propylene diene monomer rubber (EPDM) can be used for the shoe cover.

[0048] One side of the heat shrinkable material is coated with a heat activated adhesive. The heat activated adhesive is activated at low temperatures again in the range of 50 C.-65 C. Such adhesives are low temperature clear elastomeric adhesives include, for example, adhesives sold under the designation 3M Scotch-Grip plastic adhesives 4693 and 4693H by 3M Company, St. Paul, Minn. and sold under the designation Tribond 1277 by Trillium Products Ltd., Waterfoot, Lancashire, UK.

[0049] One commercial embodiment employs 10 mil to 20 mil thick EVA as the material for the shoe cover. It has been found that EVA adheres to the surface of the shoe when heated and, therefore, additional adhesive is not required when EVA is used as the material for the shoe cover.

[0050] Before covering the athletic shoe or soccer boot, the sheet material is preformed over a shoe-shaped mandrel to produce a preformed shoe cover blank 20 shown in FIGS. 3-9, which can be done, for example, through vacuum forming. The preformed shoe cover blank 20 has an upper portion 32 that conforms to the basic shape of the upper of an athletic shoe 24 (FIGS. 16-26). The preformed shoe cover blank 20 also has a seam portion 40 with edges 12. The seam portion 40 wraps around the seam between the upper and the soul of the shoe 24 and covers a portion of the outsole 28 of the shoe 24. The preformed shoe cover blank 20 further has tabs 14 (while two tabs are shown, more than two tabs may be used in certain embodiments) that wrap around the arch portion of the outsole of the shoe 24 as best seen in FIG. 23. The preformed shoe cover blank 20 also has an opening 18 extending from near the toe portion 50 of the preformed shoe cover blank 20. The opening 18 accommodates the laces or closures 46 of the shoe 24 when the shoe cover 10 is in place as shown in FIG. 23. Also as shown in FIG. 23, the shoe cover 10 only wraps around a portion of outsole 28 of the shoe 24 in order to leave the cleats 30 exposed.

[0051] FIGS. 16-22 illustrate the sequence for attachment of the preformed shoe cover blank 20 to the shoe 24. The preformed shoe cover blank 20 is placed on the shoe 24 as shown in FIGS. 16 and 17. Starting with FIGS. 18 and 19, the connecting portions 14 of the preformed shoe blank 20 are folded under the arch of the outsole 28 of the shoe 24, and the edges 12 of the preformed shoe cover blank 20 are likewise folded under the outsole 28 around the seam of the shoe. A heat source 52, such as a hair dryer or a heat gun, applies heat to the heat shrinkable preformed shoe cover blank 20. FIGS. 20-22 show the preformed shoe cover blank 20 shrinking into engagement with the contours of the shoe 24. At the same time, the applied heat causes adhesive, positioned on the side of the preformed shoe cover blank 20 adjacent the shoe 24, to activate and bind the now conforming shoe cover 10 to the athletic shoe or soccer boot 24.

[0052] FIGS. 23-26 show the shoe cover 10 conformed to and attached to the shoe 24 with the cleats 30 exposed on the outsole 28 and the laces or closures 46 exposed through the opening 18.

[0053] FIG. 27 shows another embodiment 110 of the shoe cover 10. The shoe cover 110 is in all material respects the same as shoe cover 10 except for the connection portion 14 that passes under the arch 42 of the shoe 24. The opposite ends of the connection portion 14 of the shoe cover 10 are connected together by adhesive. The shoe cover 110, however, has a belt portion 14b and a buckle portion 14a. Once the shoe cover 110 has been shrunk around the shoe 24, the belt portion 14b is inserted into the buckle portion 14a and tightened under the arch 42 of the shoe 24 in order to assure a snug fit around the arch 42 of the shoe 24.

[0054] While this invention has been described with reference to preferred embodiments thereof, it is to be understood that variations and modifications can be affected within the spirit and scope of the invention as described herein and as described in the appended claims.

[0055] As shown in FIG. 34, the shoe cover 10 can be formed with three dimensional images 200 extending from an outer surface of the shoe cover 10. Such images could include, for example, team logos or logos of athletic associations. Such symbols can also be printed as two dimensional images on the shoe cover 10.

[0056] In certain embodiments, a shoe can be manufactured with a shoe cover as described above applied to the shoe at the factory.

[0057] The above described embodiments, while including the preferred embodiment and the best mode of the invention known to the inventor at the time of filing, are given as illustrative examples only. It will be readily appreciated that many deviations may be made from the specific embodiments disclosed in this specification without departing from the spirit and scope of the invention. Accordingly, the scope of the invention is to be determined by the claims below rather than being limited to the specifically described embodiments above.
