FIELD OF THE INVENTION

[0004] The present invention generally relates to shoe construction and, more particularly, to a shoe having self-draining ports.

BACKGROUND OF THE INVENTION

[0005] It is well know that shoes, such as leather shoes, without special treatment allow penetration of outside moisture into the interior of the shoe and thus the wearer's feat can get wet. This is do to the porous nature of shoe construction, such as stitching, the porous nature of many materials used, such as leather. One approach to solve this problem has been to “waterproof” leather shoes by application of oil, wax, latex or rubber. While such methods close the leather, they do not close other openings such as at the stitching. Thus water still can enter the shoe and remain inside until the shoe is removed and the water drained. Another approach has been to construct shoes which are completely waterproof, such as rubber or plastic shoes. While such shoes prevent the entry of water, these shoes are generally uncomfortable and do not allow the feet to breath. Thus, resulting in perspiration moisture gather inside the shoe and remaining inside until the shoe is removed. Yet another approach has been to provide an inner liner constructed from water impervious but perspiration vapor impervious material such as GORE-TEX or SYMPATEX. While this approach may adequately keep the foot dry, a large amount of water can accumulate in the shoe and remain inside until the shoe is removed. This is particularly a problem when the shoes are worn near or in sources of water such as are boat and fishing shoes. Accordingly, there is a need in the art for a shoe which does not allow liquid or moisture to accumulate and remain therein.

SUMMARY OF THE INVENTION

The illustrated upper 12 also has conventional front lacing 36 engageable in eyelets 38 along opposed sides of the tongue 34. The upper 12 may also be provided with suitable lining and/or padding as desired.

[0027] As best shown in FIGS. 3-6, the sole 16 includes an outsole 40 having a main or bottom wall 42 which forms the bottom of the shoe 12 and a side wall 44 which upwardly extends around the periphery of the bottom wall 42. The bottom surface of the main wall 42 is preferably adapted to be a non-skid surface. The upper surface 48 of the main wall 42 has drain passages or channels 50 formed therein as described in more detail hereinafter. The illustrated side wall 44 is sized and shaped so that the upper 12 can be secured to the sole 16, preferably by stitching 52 the upper 12 to the sole 16. It is noted, however, that other construction methods of securing the upper 12 to the sole 16 can be utilized such as, for example, the use of adhesives and/or midsoles. The outsole 40 is preferably molded of a rubber or elastomer material but can alternatively be formed of other suitable materials.

[0028] The plurality of drain ports or apertures 18 include openings or apertures 54 formed in the side wall 44 of the outsole 40 so that liquid or moisture within the shoe cavity 14 can automatically drain out of the shoe 12 by gravity and movement of the shoe 12. The illustrated outsole 40 is provided with eight drain ports 18 which includes four pairs of the drain ports 18 located on opposite sides of the outsole 40. The first pair 18a of the drain ports 18 is located at the forward or toe region 56 of the outsole 40. The second pair 18b of the drain ports 18 is located just forward of an arch region 58 of the outsole 40. The third pair 18c of the drain ports 18 is located just rearward of the arch region 58 of the outsole 40. The fourth pair 18d of the drain ports 18 is located at a rearward or heal portion 60 of the outsole 40. The illustrated drain ports 18 include the circular openings 54 which horizontally extend through the side wall 44 of the out sole 40. The openings 54 preferably have a diameter of about {fraction (3/16)} inches but can have other suitable dimensions. The openings 54 are preferably vertically positioned so that they are located at least partially below the top or upper surface 48 of the outsole 48. It is noted that the drain ports 18 can alternatively have any suitable size, shape, location and orientation.

[0029] The drain channels 50 are formed in the upper surface 48 at the drain ports 18 so that liquids and moisture can be directed to the drain ports 18 below the upper surface 48 of the outsole 40. Preferably, the drain channels 50 extend laterally across the outsole 40 between the pairs of the drain ports 18. The illustrated outsole 40 has four drain channels 50a, 50b, 50c, 50d corresponding to the four pairs 18a, 18b, 18c, 18d of drain ports 18. The first drain channel 18a is located at the forward or toe region 56 of the outsole 40 and connecting the first pair 18a of drain ports 18. The second drain channel 50b is located just forward of an arch region 58 of the outsole 40 and connecting the second pair 18b of drain ports 18. The third drain channel 50c is located just rearward of the arch region 58 of the outsole 40 and connecting the third pair 18c of drain ports 18. The fourth drain channel 50d is located at the rearward or heal portion 60 of the outsole 40 and connecting the fourth pair 18d of drain ports 18. It is noted, however, that the drain ports 18 can alternatively have individual drain channels 50 or more than two drain ports 18 can be connected by one of the drain channels 50.

[0030] The illustrated drain channels 50 have a generally rectangular shape in cross section having a generally flat bottom wall 62 and opposed generally flat side walls 64 extending upwardly from the sides of the bottom wall 62. Shaped in this manner the drain channels 50 are open at their top so that water or moisture with the shoe cavity 14 can enter the drain channels 50 and be directed toward the drain ports 18 to exit the shoe 12. In this regard, it is noted that the drain channels 50 can be advantageously arched or angled downwardly toward the drain ports 18 to aid in the flow of liquid and moisture toward the drain ports 18. It is also noted that the drain channels 50 can alternatively have other shapes in cross-section such as, for example, square, triangular, or arcuate.

[0031] The drain ports 18 preferably each include an eyelet 66 therein. As best shown in FIGS. 7 to 9, the illustrated eyelet 66 includes a tubular portion 68, a flange portion 70, and an attachment portion 72. The tubular portion 68 forms a hollow interior passage 74 that extends the length of the eyelet 66 for the passage of liquid or moisture through the eyelet 66. The tubular portion 68 is sized and shaped to extend through the drain port opening 54 in the outsole 40. The flange portion 70 outwardly extends from an outer end of the tubular portion 68 in a radial direction and is preferably sized and shaped to secure the eyelet 66 to the outsole 40 by preventing the passage of the eyelet 66 entirely through the drain port opening 54. The illustrated attachment portion 72 is a plurality of fingers 76 formed at the inner end of the tubular portion 68 opposite the flange portion 70. The fingers 76 are sized and shaped so that they can be plastically deformed in an outward direction to secure the eyelet 66 to the outsole 40 within the drain port opening 54 as described in more detail hereinafter. The illustrated eyelet 66 is metal but the eyelet 66 can alternatively be formed of any other suitable material.

[0032] The illustrated eyelet 66 is provided with a screen 78 to substantially prevent the passage of objects into the drain port 18 and drain channel 50. The screen 78 is preferably provided with a plurality of small openings or apertures 80, substantially smaller than the drain port opening 54 itself, which permit the passage of liquids therethrough but block most solid objects other than small particles. The illustrated screen 78 has a main panel 82 which is generally flat and a flange 84 extending around the periphery of the main panel 82. The plurality of small openings 80 are provided in the main panel 82. The flange 84 is sized and shaped to extend over the edge of the of the eyelet flange portion 70 to secure the screen 78 to the eyelet flange portion 70. It is noted that while the illustrated screen 78 is a separate component from the eyelet 66 and secured to the eyelet 66 by the flange 84, the screen 78 can be alternatively formed unitary with the eyelet 66 or alternatively secured to the eyelet 66 in other suitable manners. The illustrated screen 78 is generally oval shaped but the screen 78 can be alternatively sized and shaped in any suitable manner.

[0033] The illustrated eyelet 66 is preferably attached utilizing a ferrule 86 at the inner side of the outsole side wall 44. As best shown in FIGS. 10 to 12, the ferrule 86 includes a tubular portion 88 and a flange portion 90. The tubular portion 88 forms a hollow interior passage 92 that extends the length of the ferrule 86 for the passage of the eyelet 66 and liquid or moisture through the ferrule 86. The tubular portion 88 is sized and shaped to partially extend through the drain port opening 54 of the outsole 40 and over the tubular portion 68 of the eyelet 66. The flange portion 90 outwardly extends in a radial direction from an outer end of the tubular portion 88 and is preferably sized and shaped to secure the ferrule 86 to the outsole side wall 44 by preventing the passage of the ferrule 86 entirely through the drain port opening 54. The flange portion 90 preferably has an arcuate shape to aid in the deformation and holding of the fingers 76 of the eyelet 66. The illustrated ferrule 86 is metal but the ferrule 86 can alternatively be formed of any other suitable material.

[0034] As best shown in FIGS. 4 to 6, the eyelet 66 is secured to the outsole side wall 44 by extending the tubular portion 68 of the eyelet 66 though the drain port opening 54 with the screen 78 and flange portion 70 engaging the outer surface of the outsole side wall 44. It is noted that the drain port opening 54 is preferably provided with a counter bore or recess 94 at the outer surface of the outsole side wall 44 to at least partially receive the eyelet flange portion 70 and/or screen therein 78. The ferrule 86 is placed over the tubular portion 68 of the eyelet 66 and extends into the drain port opening 54 with the flange portion 90 of the ferrule 86 engaging the inner surface of the outsole side wall 44. The fingers 76 of the eyelet 66 are plastically deformed radially outward over the flange portion 90 of the ferrule 86. Installed in this manner, the eyelet 66 is secured to the outsole side wall 44 within the drain port opening 54. Liquid and moisture within the drain channel 50 is free to pass through the interior passage 74 of the eyelet 66 and the small openings 80 of the screen 78 to exit the shoe 12 to the exterior space surrounding the shoe 12.

[0035] As best shown in FIG. 3, the insole 20 is located within the shoe cavity and supported by the upper surface 48 of the outsole 40. The insole 20 is preferably shaped to substantially cover the entire upper surface 48 of the outsole 40 and to provide support for the person's foot when located within the shoe cavity 14. The insole 20 also preferably provides both cushioning for the person's foot and a soft upper surface for engagement by the person's foot. The illustrated insole 20 is a composite of a lower layer of a foamed polymer material and an upper layer of fabric. It is noted, however, that the insole 20 can be alternatively formed of other suitable materials. The insole 20 is provided with a plurality of openings or passages 96 vertically extending entirely therethrough to provide passages for liquids and moisture to pass through the insole 20. The openings 96 are preferably provided in each of the toe, arch and heal regions 56, 58, 60 of the shoe 12.

[0036] As best shown in FIG. 3, the liner 22 is located within the shoe cavity 14 and supported by the upper surface 48 of the outsole 40. The liner 22 is located between the outsole 40 and the insole 20. The liner 22 is preferably shaped to substantially cover the entire upper surface 48 of the outsole 40. The liner 22 preferably formed of material which is impervious to water, impervious to water but pervious to water vapor, or partially impervious to water. It is noted, however, that the liner 22 can be alternatively formed of other suitable materials such as water pervious materials. The liner 22 is provided with a plurality of openings 98 vertically extending entirely therethrough to provide passages for liquids and moisture to pass through the liner 22 from the shoe cavity 14 to the drain channels 50. The openings 98 are provided at the drain channels 50 so that liquids passing through the openings 98 directly enter the drain channels 50. The illustrated liner 22 has four rows of the openings 98 corresponding to the four drain channels 50a, 50b, 50c, 50d. The liner 22 is preferably secured to the upper 12 by stitching and also adhered to the upper surface 48 of the outsole 40 such as by adhesive. It is noted however that the liner 22 can be secured to the upper 12 and/or outsole 40 in other suitable manners. Preferably, the insole 20 is removable from the shoe cavity 14 and supported on the liner 22 but can alternatively be secured to the upper 12, liner 22, and/or sole 16 in any suitable manner if desired.

[0037] From the foregoing description, it is apparent that the shoe 12 according to the present invention is self draining. Any liquids such as water entering the shoe cavity through the opening 26 or other passages or openings in the upper 12 or perspiration or other moisture formed within the shoe cavity 14 will automatically drain from the shoe cavity 14 by dropping to the insole 20, passing through the openings 96 of the insole 20, and passing through the openings 98 of the liner 22 to the drain channels 50. Once in the drain channels 50 below the liner 22, liquid is directed by the channels 50 to the drain ports 18 where liquid passes through the interior passage 74 of the eyelet 66 and the small openings 80 of the screen 78 to exit the shoe 12 to ambient or exterior space surrounding the shoe 12. The shoe 12 is self draining in that liquid automatically drains from the shoe cavity 14 by gravity and movement of the shoe 12 without removal of the person's foot from the shoe 12. It is apparent that the present invention has particular applicability to types of shoes which are typically worn around water and other liquids such as the illustrated boat or fishing shoe. It should be noted, however, that the present invention is also applicable to other types of shoes 12 such as athletic shoes, work boots, hunting boots, and hiking boots.

[0038] From the foregoing disclosure and detailed description of certain preferred embodiments, it will be apparent that various modifications, additions and other alternative embodiments are possible without departing from the true scope and spirit of the present invention. For example, it will be apparent to those skilled in the art, given the benefit of the present disclosure, that the upper 12, the sole 16, the eyelet 66, and the screen 78 can each have many different configurations and can be formed of many different materials. The embodiments discussed were chosen and described to provide the best illustration of the principles of the present invention and its practical application to thereby enable one of ordinary skill in the art to utilize the invention in various embodiments and with various modifications as are suited to the particular use contemplated. All such modifications and variations are within the scope of the present invention as determined by the appended claims when interpreted in accordance with the benefit to which they are fairly, legally, and equitably entitled.
