The present invention relates generally to the field of sports footwear, and more particularly to manufacturing and construction of performance footwear.
The present embodiments are generally directed to sports footwear, and more particularly to manufacturing and construction of performance footwear, such as ice skate boots.
The right performance footwear, especially as it applies to sports such as hockey, can give an athlete a competitive edge. In that regard, there are a number of factors considered in the production of performance footwear including weight, foot support, performance durability and of course manufacturing. It is to innovations related to improving hard-shell sports footwear that the subject matter disclosed herein is generally directed.
The present embodiments are generally directed to hard shell sports footwear, and more particularly to manufacturing and construction of performance footwear, such as ice skate boots.
In that light, certain embodiments of the present invention contemplate an athletic boot comprising an additive manufactured integrated sole and foot form that includes a sole form and foot form. The athletic boot further comprises a composite overlay that essentially covers a majority of an outer surface of the sole form and a majority of an outer surface of the foot form. A majority meaning around 75%-80%. Certain embodiments envision the overlay covering the integrated sole and foot form up to an overlay border that runs along the top of the integrated sole and foot form. If the athletic boot is an ice skate boot, the overlay leaves open the mounting holes in the overlay sole portion of the ice skate. Some embodiments envision at least one type of compressible insulation layer fitted against essentially all of an inner surface of the sole and the foot form, the athletic boot is configured to be worn on a human foot. The compressible insulation is intended to add comfort from an otherwise stiff additive manufactured integrated sole and foot form.
Yet another embodiment contemplates athletic footwear comprising an additive manufactured integrated sole and foot form that includes a sole form and foot form in addition to a composite overlay that essentially covers between 50%-90% of an outer surface of the sole form and between 50%-90% of an outer surface of the foot form. The athletic footwear is configured to be worn on a human foot.
An embodiment for a method of manufacturing an athletic boot can comprise 3-D printing an additive manufactured integrated sole and foot form that includes a sole form and foot form. Next, apply a composite overlay to the additive manufactured integrated sole and foot form in a manner that essentially covers at least 50% of an outer surface of the sole form and at least 50% of an outer surface of the foot form. In certain embodiments, at least one type of compressible insulation layer can be fitted against essentially all of an inner surface of the sole and the foot form. The athletic boot is configured to be worn on a person's foot.
Initially, this disclosure is by way of example only, not by limitation. Thus, although the instrumentalities described herein are for the convenience of explanation, shown and described with respect to exemplary embodiments, it will be appreciated that the principles herein may be applied equally in other similar configurations involving the subject matter directed to the field of the invention. The phrases “in one embodiment”, “according to one embodiment”, and the like, generally mean the particular feature, structure, or characteristic following the phrase, is included in at least one embodiment of the present invention and may be included in more than one embodiment of the present invention. Importantly, such phases do not necessarily refer to the same embodiment. If the specification states a component or feature “may”, “can”, “could”, or “might” be included or have a characteristic, that particular component or feature is not required to be included or have the characteristic. As used herein, the terms “having”, “have”, “including” and “include” are considered open language and are synonymous with the term “comprising”. Furthermore, as used herein, the term “essentially” is meant to stress that a characteristic of something is to be interpreted within acceptable tolerance margins known to those skilled in the art in keeping with typical normal world tolerance, which is analogous with “more or less.” For example, essentially flat, essentially straight, essentially on time, etc. all indicate that these characteristics are not capable of being perfect within the sense of their limits. Accordingly, if there is no specific +/− value assigned to “essentially”, then assume essentially means to be within +/−2.5% of exact. The term “connected to” as used herein is to be interpreted as a first element physically linked or attached to a second element and not as a “means for attaching” as in a “means plus function”. In fact, unless a term expressly uses “means for” followed by the gerund form of a verb, that term shall not be interpreted under 35 U.S.C. § 112 (f). In what follows, similar or identical structures may be identified using identical callouts.
With respect to the drawings, it is noted that the figures are not necessarily drawn to scale and are diagrammatic in nature to illustrate features of interest. Descriptive terminology such as, for example, upper/lower, top/bottom, horizontal/vertical, left/right and the like, may be adopted with respect to the various views or conventions provided in the figures as generally understood by an onlooker for purposes of enhancing the reader's understanding and is in no way intended to be limiting. All embodiments described herein are submitted to be operational irrespective of any overall physical orientation unless specifically described otherwise, such as elements that rely on gravity to operate, for example.
The present embodiments are directed to an athletic boot comprising an additive manufactured integrated sole and foot form that includes a sole form and foot form. The additive manufactured boot is referred to herein as a form because it is 3-D printed. More specifically, 3-D printed elements are synonymous with additive manufactured elements. The athletic boot further comprises a composite overlay that essentially covers between 50-90% of an outer surface of the sole form and between 50-90% of an outer surface of the foot form. Certain embodiments envision the overlay covering the integrated sole and foot form up to an overlay border that runs along the top of the integrated sole and foot form. In an embodiment where the athletic boot is an ice skate boot; the overlay leaves open the mounting holes in the overlay sole portion of the ice skate. Some embodiments envision at least one type of compressible insulation layer fitted against essentially all an inner surface of the sole and the foot form, the athletic boot is configured to be worn on a human foot. The compressible insulation is intended to add comfort from an otherwise stiff additive manufactured integrated sole and foot form.
The two main portions of the sole and foot form 102 are a form sole portion 104 and a form foot portion 106. The inside of the form sole portion 104A is shown here and the outside of the form sole portion 104B is facing downward (when generically referring to the form sole portion 104, the callout is simply 104). The form foot portion 106 is defined by a pair of opposing foot sides 108 (left and right), a toe box 110 and a heel portion 112. In the present embodiment, the form foot portion 106 does not include a tongue 160, which is shown in
The overlay 120 is a shell that encapsulates and conforms to most of the sole and foot form 102 up to the overlay border 118. In certain embodiments, the overlay top edge 122 butts up against the overlay border 118. Other embodiments envision the overlay top edge 122 tucked at least partially inside of the overlay border gap 119 such that the overlay top edge 122 is not exposed. Certain embodiments envision the overlay 120 being a composite carbon fiber shell, fiberglass shell, Kevlar, some combination, etc. The overlay top edge 122 may be rough, sharp or otherwise tactilely unpleasant to a person touching it, hence having the overlay top edge 122 tucked inside of the overlay border gap 119 prevents a person from being able to touch the overlay top edge 122, thus avoiding any suboptimal tactile experience (like fingers getting pricked or cut). As depicted here, the overlay 120 encapsulates the outside 105 of the sole and foot form 102. Certain embodiments envision the overlay 120 being a composite carbon fiber shell that is manually wrapped over the outer form 105 of the sole and foot form 102. The inner surface of the overlay sole portion 124 mates with or otherwise conforms to the outer portion of the form sole portion 104B. Also shown are the front mounting platform 126 and mounting hole/aperture 130.
With reference to the overlay 120, certain embodiments envision a fiber mesh soaked in a liquid resin being wrapped over the sole and foot form outside surface 105 up to the overlay boarder 118 and then cured and hardened into a composite wrap. Accordingly, the shape of the overlay 120 matches the shape of the sole and foot form 102. Hence, as shown at the outer overlay sole portion 124B, the overlay front mounting platform 136 conforms to the form's front mounting platform 126 and the overlay rear mounting platform 138 conforms to the form's rear mounting platform 128. As mentioned earlier, the overlay top edge 122 can be tucked into the overlay border gap 119. For reference, the overlay heel portion 132 conforms to the form heel portion 112, the overlay toe region 140 conforms to a portion of the form toe box 110, and the overlay foot sides 148 conform to the form foot sides 108.
