The present invention relates to articles of footwear and uppers for articles of footwear that include an integrated pocket. The integrated pocket may be configured to hold an electronic module, e.g., for measuring data relevant to athletic performance metrics.
Conventional articles of athletic footwear include two primary elements, an upper and a sole structure. The upper may provide a covering for the foot that securely receives and positions the foot with respect to the sole structure. In addition, the upper may have a configuration that protects the foot and provides ventilation, thereby cooling the foot and removing perspiration. The sole structure may be secured to a lower surface of the upper and generally is positioned between the foot and any contact surface. In addition to attenuating ground reaction forces and absorbing energy, the sole structure may provide traction and control potentially harmful foot motion, such as over pronation.
The upper forms a void on the interior of the footwear for receiving the foot. The void has the general shape of the foot, and access to the void is provided at an ankle opening. Accordingly, the upper extends over the instep and toe areas of the foot, along the medial and lateral sides of the foot, and around the heel area of the foot. A lacing system often is incorporated into the upper to allow users to selectively change the size of the ankle opening and to permit the user to modify certain dimensions of the upper, particularly girth, to accommodate feet with varying proportions. In addition, the upper may include a tongue that extends under the lacing system to enhance the comfort of the footwear (e.g., to moderate pressure applied to the foot by the laces), and the upper also may include a heel counter to limit or control movement of the heel.
This Summary is provided to introduce some general concepts relating to this technology in a simplified form that are further described below in the Detailed Description. This Summary is not intended to identify key features or essential features of the invention.
Aspects of this technology relate to uppers for articles of footwear, articles of footwear including the uppers, methods of making the uppers, methods of making articles of footwear including the uppers, and/or methods of using the uppers and/or articles of footwear, wherein the uppers include an integrated pocket. In at least some examples, the pocket may be accessible from the outside of the upper and/or article of footwear. In at least some examples, the pocket may be formed solely from structural components of the footwear upper, i.e., structural components provided in the upper for purposes other than to form the pocket. As some more specific examples, the footwear upper components forming the pocket may extend beyond the interior chamber of the pocket by at least 25 mm (and in some examples, at least 40 mm, at least 50 mm, at least 75 mm, or even at least 100 mm) in one or more directions (e.g., forward, rearward, upward, and/or downward from the pocket's interior chamber). The pocket may be formed without sewn seams, in at least some examples. The pocket may house an electronic module, such as one or more sensors for measuring features of an athlete's performance (e.g., movement speed; movement distance; kick speed, velocity, and/or power; ball touches; playing time; etc.).
The following Detailed Description will be better understood when considered in conjunction with the accompanying drawings in which like reference numerals refer to the same or similar elements in all of the various views in which that reference number appears.
In the following description of various examples of footwear structures and components according to the present disclosure, reference is made to the accompanying drawings, which form a part hereof, and in which are shown by way of illustration various example structures and environments in which aspects of this technology may be practiced. It is to be understood that other structures and environments may be utilized and that structural and functional modifications may be made to the specifically described structures, functions, and methods without departing from the scope of the present disclosure.
“Footwear,” as that term is used herein, means any type of wearing apparel for the feet, and this term includes, but is not limited to: all types of shoes, boots, sneakers, sandals, thongs, flip-flops, mules, scuffs, slippers, sport-specific shoes (such as golf shoes, tennis shoes, baseball cleats, soccer or football cleats, ski boots, basketball shoes, cross training shoes, dance shoes, urban dance shoes, etc.), and the like.
Various structures and parameters of articles of footwear and uppers thereof are described based on a “longitudinal length” parameter L. Note
The term “rearward” as used herein means at or toward the heel region of the article of footwear (or component thereof), and the term “forward” as used herein means at or toward a forefoot or forward toe region of the article of footwear (or component thereof). Unless otherwise defined, the terms “heel” or “heel region” refer to a region bounded by parallel planes at 0 L and 0.3 L, the term “midfoot” or “arch” refers to a region bounded by parallel planes at 0.3 L and 0.6 L, and the term “forefoot” refers to a region bounded by parallel planes at 0.6 L and 1.0 L. Also, the term “lateral” means the “little toe” side or outside edge of an article of footwear or component thereof (e.g., an upper, a sole structure, etc.), and the term “medial” means the “big toe” side or inside edge of an article of footwear or component thereof (e.g., an upper, a sole structure, etc.).
This application and/or its claims use the adjectives, e.g., “first,” “second,” “third,” and the like, to identify certain components and/or features relating to this technology. These adjectives are used merely for convenience, e.g., to assist in maintaining a distinction between components and/or features of a specific structure. Use of these adjectives should not be construed as requiring a specific order or arrangement of the components and/or features being discussed. Also, use of these specific adjectives in the specification for a specific structure does not require that the same adjective be used in the claims to refer to the same part (e.g., a component or feature referred to as the “third” in the specification may correspond to any numerical adjective used for that component or feature in the claims).
As noted above, articles of footwear, footwear uppers, and methods in accordance with aspects of this technology include forming the footwear upper to include an integrated pocket, e.g., accessible from the outside of the upper and/or article of footwear. This pocket may be formed solely from structural components of the footwear upper, i.e., structural components provided in the upper for purposes other than to form the pocket. In some examples, one or more components forming the pocket and/or one or more of the interior surfaces of the pocket will extend beyond the heel region of the upper, e.g., into the midfoot region of the upper, into the forefoot region of the upper, to the rear heel seam of the upper, to the forward toe area of the upper, into an instep region of the upper, forming and/or supporting a lace-engaging component of the upper, etc. Additionally or alternatively, one or more components forming the pocket and/or one or more of the interior surfaces of the pocket will extend beyond the perimeter of the pocket's interior area, e.g., to the top edge of the foot-receiving opening of the upper, to the junction between the upper and the sole structure, etc. Additionally or alternatively, in some specific examples of this technology: (i) one footwear upper component forming the pocket may have one major surface exposed in the interior of the pocket structure (forming at least a portion of an interior wall of the pocket) and its opposite major surface exposed in the foot-receiving chamber of the footwear (directly exposed to the wearer's foot in the interior of the footwear) and/or (ii) one footwear upper component forming the pocket may have one major surface exposed in the interior of the pocket structure (forming at least a portion of an exterior wall of the pocket) and its opposite major surface exposed at the exterior surface of the footwear (directly exposed to the external environment). In at least some examples of this technology, if component parts forming the pocket were removed from the upper, the upper would be missing at least one essential structural part (e.g., at least a portion of a sidewall of the upper would be missing, in some instances exposing the wearer's foot) such that the remaining upper components would not provide the structural features and/or integrity needed for the footwear's intended use.
Some aspects of this technology relate to uppers for articles of footwear and articles of footwear including the uppers, wherein the uppers include: (a) a first upper component having a first inward facing surface (facing the shoe interior) and a first outward facing surface (facing the external environment); and (b) a second upper component having a second inward facing surface and a second outward facing surface, wherein a portion of the second inward facing surface is fixed with a portion of the first outward facing surface. The first upper component and the second upper component define a pocket that includes: (a) the first outward facing surface, (b) the second inward facing surface, (c) a slit extending through the second upper component from the second outward facing surface to the second inward facing surface, and (d) an unfixed space between the first outward facing surface and the second inward facing surface where the second inward facing surface is unfixed with the first outward facing surface. The slit provides access to the unfixed space. In some examples, the pocket may consist of or consist essentially of the first upper component and the second upper component bonded together to form an outer perimeter of the unfixed space. The outer perimeter or outer boundary of the unfixed space of the pocket may be defined by an attached perimeter where the second inward facing surface is attached to the first outward facing surface. In at least some examples, 100% of this attached perimeter is formed in a “sewn seam-free manner” (e.g., by adhesive bonding, welding techniques, adhesive-free bonding, etc., without any sewing or stitching). The pocket may be located completely within the heel region of the upper and/or article of footwear. The upper may be engaged with a sole structure to form an article of footwear.
Additional aspects of this technology relate to methods of forming footwear uppers and/or articles of footwear (e.g., the types described above) that include: (a) providing a first upper component having a first surface and a second surface opposite the first surface; (b) forming a slit in a second upper component, the second upper component having a third surface and a fourth surface opposite the third surface, the slit extending from the third surface to the fourth surface; (c) arranging the first upper component and the second upper component such that the second surface directly faces the third surface; (d) creating a pocket forming arrangement between the second surface and the third surface (e.g., by placing at least a first portion of an adhesion-inhibiting component between the second surface and the third surface adjacent the slit, by removing adhesive or adhesive precursor from the portion of the second surface and/or the third surface, by not applying adhesive or adhesive precursor to a portion of the second surface and/or the third surface, by placing a three-dimensional blank between the second surface and the third surface, etc.); and (e) applying heat and/or pressure to bond the first upper component to the second upper component at locations around the pocket forming arrangement (e.g., the adhesion-inhibiting component) to define a pocket as unfixed space between the second surface and the third surface, the unfixed space forming due to the presence of the pocket forming arrangement (e.g., the adhesion-inhibiting component). The slit provides access to the unfixed space and an opening to the pocket. In some examples, the pocket as formed will consist of or consist essentially of the first upper component and the second upper component bonded together to form an outer perimeter of the unfixed space. The outer perimeter or outer boundary of the unfixed space of the pocket as formed may be defined by an attached perimeter where the inward facing surface is attached to the outward facing surface. In at least some examples, 100% of the attached perimeter will be formed in a sewn seam-free manner (e.g., by adhesive bonding, by welding techniques, by adhesive-free bonding, etc., without any sewing or stitching). Alternatively, sewing or stitching could be used to attach the first upper component and the second upper component together around the pocket perimeter. The pocket may be formed completely within the heel region of the upper and/or article of footwear. The methods further may include engaging the upper with a sole structure to form an article of footwear.
Still additional aspects of this technology relate to uppers and/or articles of footwear in which an electronic module is included in the pocket. The electronic module may include various types of electronic devices, such as: a speed and/or distance monitor, an accelerometer sensor, a pedometer, a display device, a light emitting device, etc. The electronic module may be battery powered such that no electrical wiring or electronic connectors are present in, present at, or extend through the pocket. Still additional aspects of this technology relate to use of uppers and/or articles of footwear including such integrated pockets, e.g., to house an electronic module, to receive data relating to athletic performance metrics relating to the wearer's use of the article of footwear, etc. As some more specific examples, aspects of this technology may be used to form a sensor-receiving pocket in football cleats (e.g., American football or soccer), and that sensor may be used to record data relating to a player's performance on the field and/or pitch.
Given the general description of features, examples, aspects, structures, processes, and arrangements according to certain examples of this technology provided above, a more detailed description of specific example footwear uppers, articles of footwear, and/or methods in accordance with this technology follows.
Referring to the figures and following discussion, various examples of footwear uppers, articles of footwear, and methods in accordance with aspects of this technology are described.
In addition to illustrating features of terminology used in this application as discussed above,
The upper 102 defines a foot-receiving opening 106 that provides access to an interior foot-receiving chamber defined at least in part by the upper 102 (and optionally, at least in part by the sole structure 104). A securing system (e.g., lace 108, but any other type of securing system (e.g., strap systems, hook-and-loop fasteners, buckles, etc.) also may be used) is provided to secure the article of footwear 100 to a wearer's foot.
The pocket 200 of this illustrated example is formed as part of the upper 102 for the article of footwear 100 and directly from structural component parts of the upper 102. The upper 102 may include a base upper component 102A, which may comprise a knit material, another fabric material, a mesh material, a lining material, a foam material, or another upper material, including upper materials conventionally known and used in the footwear art. The pocket 200 is formed from: (a) a first upper component 102B having a first inward facing surface 102BI and a first outward facing surface 102BO; and (b) a second upper component 102C having a second inward facing surface 102CI and a second outward facing surface 102CO. Second outward facing surface 102CO of this example forms an exposed exterior surface of the footwear upper 102. The inward facing surface 102BI of the first upper component 102B may be fixed to (e.g., bonded to, such as by an adhesive or hot melt bond) the outward facing surface 102AO of the base upper component 102A. Further, a portion of the second inward facing surface 102CI of the second upper component 102C is fixed with (e.g., bonded to, such as by an adhesive or hot melt bond) a portion of the first outward facing surface 102B0 of the first upper component 102B. The bond between the first upper component 102B and the second upper component 102C is shown as elements 212 in
By selectively bonding portions of the second inward facing surface 102CI of the second upper component 102C with the first outward facing surface 102BO of the first upper component 102B, the first upper component 102B and the second upper component 102C define the pocket 200. More specifically, the pocket 200 is formed by: (a) the first outward facing surface 102BO of the first upper component 102B, (b) the second inward facing surface 102CI of the second upper component 102C, and (c) an unfixed space 200A located between the first outward facing surface 102BO and the second inward facing surface 102CI where the second inward facing surface 102CI is unfixed with the first outward facing surface 102BO (e.g., due to the absence of an adhesive or lack of adhesion at the location of the unfixed space 200A). The boundary 200B between (a) the bonded locations of the second inward facing surface 102CI with the first outward facing surface 102BO and (b) the unfixed space 200A is shown by broken lines in
In this illustrated example pocket 200, the outer boundary 200B of the unfixed space 200A of the pocket 200 is defined by an attached perimeter where the second inward facing surface 102CI is attached to the first outward facing surface 102BO. In at least some examples of this technology, 100% of this attached perimeter is formed in a sewn seam-free manner (i.e., without sewing or stitching to form the attached perimeter and/or boundary 200B of the pocket 200). More specifically, the outer boundary 200B of the unfixed space 200A of the pocket 200 in this illustrated example includes: (i) a top edge 200TE where the first outward facing surface 102BO is bonded to the second inward facing surface 102CI, (ii) a bottom edge 200BE where the first outward facing surface 102BO is bonded to the second inward facing surface 102CI, and (iii) a forward edge 200FE where the first outward facing surface 102BO is bonded to the second inward facing surface 102CI, wherein the forward edge 200FE extends between the top edge 200TE and the bottom edge 200BE. See
Additional potential features of the pocket 200 include features of its size and/or orientation on the upper 102. In some examples of this technology, the total interior pocket area (or unfixed area 200A) defined by the pocket 200, i.e., the area defined inside the top edge 200TE, the bottom edge 200BE, the forward edge 200FE, and the slit 200S (see
In at least some examples of this technology, the pocket 200 will be integrally formed from two (or more) structural upper components, i.e., structural components provided in the upper 102 for purposes other than to form the pocket 200. In this illustrated example, the first upper component 102B that forms the inner side of the pocket 200 extends continuously at least from a first central rear heel location of the upper 102 (e.g., rearward of a parallel plane located at 0.05 L) at least to a first midfoot location of the upper 102 (e.g., forward of a parallel plane located at 0.4 L) and/or to another location forward of the unfixed space 200A (e.g., forward of a parallel plane located at 0.5 L, 0.6 L, or 0.7 L). Additionally or alternatively, the second upper component 102C that forms the outer side of the pocket 200 extends continuously at least from a second central rear heel location of the upper 102 (e.g., rearward of a parallel plane located at 0.05 L) at least to a second midfoot location of the upper 102 (e.g., forward of a parallel place located at 0.4 L) and/or to another location forward of the unfixed space 200A (e.g., forward of a parallel plane located at 0.5 L, 0.6 L, or even 0.7 L). In this illustrated example, the first upper component 102B provides at least a portion of the heel-containing region of the upper 102. The second upper component 102C provides abrasion resistance, stretch resistance, and/or additional heel support to the upper 102. Thus, the components 102B and 102C forming the pocket 200 extend rearward and forward well beyond the unfixed space 200A forming the pocket 200. As some more specific examples, the footwear upper components 102B, 102C forming the pocket 200 may extend beyond the unfixed space 200A (i.e., the interior chamber) of the pocket 200 by at least 25 mm (and in some examples, at least 40 mm, at least 50 mm, at least 75 mm, or even at least 100 mm) in any direction (e.g., forward, rearward, to or around the rear heel area, to or across the instep area, upward, and/or downward from the pocket 200's unfixed space 200A).
As shown in
In some examples of this technology, the structure forming the pocket 200 will consist only of or consist essentially of the first upper component 102B and the second upper component 102C bonded together to form an outer perimeter or boundary 200B of the unfixed space 200A (e.g., in a sewn seam-free manner). In the example of
While
When the pocket 200 is longitudinally long, e.g., substantially longer than the electronic module 210, once the module 210 is in the pocket 200, it can be difficult to remove, e.g., to recharge the module 210, to download data from the module, etc. In some instances, efforts to remove the electronic module 210 could result in tearing the slit 200S and/or otherwise damaging the pocket 200 or upper 102. For these reasons, the example of
In use, as the electronic module 210 is inserted into the pocket 200 (direction of arrow A in
Alternatively, if desired, the device release 500 could be vertically flipped with respect to the pocket 200 structure from the orientation shown in
Additionally or alternatively, as shown in
In the example of
To release the electronic module 210 from the pocket 200 in this example, the user 250 applies a downward and rearward force (arrow C) to the front edge 210F of the electronic module 210 as shown in
In the example of
Also, the second upper component 102C of this example includes a retaining lip 216 that extends downward to partially wrap a portion (e.g., the top) of the rearward edge 210R of the electronic module 210 and help hold the electronic module 210 within the pocket 200. If desired, some or all of the second upper component 102C (e.g., at least the region of the retaining lip 216) may be made from a rigid material, e.g., to allow the lip to engage and retain the electronic module 210. Such rigid materials may include plastics, metals, stiff fabrics, etc. As shown in
To release the electronic module 210 from the pocket 200 in this example, the user 250 applies a downward and rearward force (arrow C) to the front edge 210F of the electronic module 210 as shown in
As described above, in some examples of this technology the upper 102 may be formed, at least in part, by heating and pressing techniques, e.g., flat pressing techniques, such as the techniques described in U.S. Pat. No. 9,723,895 B2. Further aspects of methods of forming upper components including an integrated pocket 200 in accordance with some examples of this technology are described in conjunction with
In the example method steps shown in
An adhesion-inhibiting component 802 may be applied to the second upper component 102C in the area where the unfixed space 200A of the pocket 200 component is desired. In the illustrated example, the adhesion-inhibiting component 802 comprises a sheet of material 802A. The sheet of material 802A is placed to extend through the slit 200S so that a portion of the sheet of material 802A is located on the inward facing surface 102CI (shown in broken lines at the top right of
Then, the second upper component 102C (with the adhesion-inhibiting component 802 included with it) is arranged on the first upper component 102B. See arrows C and D in
The combined first upper component 102B, second upper component 102C, and adhesion-inhibiting component 802 may be mounted on a support plate 810 for pressing by press plate 812. The first upper component 102B and the second upper component 102C may have holes formed therein (e.g., along their edges), and these holes may engage pins provided on the support plate 810 or on a component held by support plate 810. Such use of holes engaging pins and pressing to engage upper components together by hot melt processes are described, for example, in U.S. Pat. No. 9,723,895 B2. Press plate 812 and/or support plate 810 may be heated to a sufficient temperature to activate the hot melt adhesive applied to one or both of first upper component 102B and/or second upper component 102C, and the plates 810, 812 may be pressed together (see force arrow F). Sufficient heat and pressure activate the hot melt adhesive thereby bonding inward facing surface 102CI of the second upper component 102C with the outward facing surface 102BO of the first upper component 102B. Once bonded, the combined first upper component 102B and second upper component 102C may be removed from the support plate 810 as a single upper component 820. See arrow E in
Due to the presence of the adhesion-inhibiting component 802, however, a portion of the inward facing surface 102CI of the second upper component 102C does not bond to the outward facing surface 102BO of the first upper component 102B (shown by dot-dash lines in
Any desired type of adhesion-inhibiting component 802 may be used with this technology. In this illustrated example, the adhesion-inhibiting component 802 comprises a release liner or release paper that extends through the slit 200S so that a portion of the release liner extends between the inward facing surface 102CI of the second upper component 102C and the outward facing surface 102BO of the first upper component 102B. The release liner (or at least one or both outer surfaces thereof) is formed from a material that does not adhere (bond) to the first upper component 102B, the second upper component 102C, and/or the hot melt adhesive under the applied heat and pressure conditions. As another example, the adhesion-inhibiting component 802 may comprise a folded sheet of paper, fabric, or other material that optionally may be allowed to remain within the upper structure (so that the facing surfaces of the paper, fabric, or other material form interior surfaces of the pocket 200). As yet another example, the adhesion-inhibiting component 802 may comprise a liquid, gel, sticker(s), or coating, e.g., applied to the first upper component 102B and/or the second upper component 102C at the area where the unfixed area 200A of the pocket 200 is desired. As yet another option, adhesion-inhibiting could be provided by not applying hot melt adhesive and/or other adhesive material to one or both of the inward facing surface 102CI of the second upper component 102C and the outward facing surface 102BO of the first upper component 102B at the desired location of the pocket 200. Such adhesion-inhibiting components 802 constitute “pocket forming arrangements,” as that term is used herein.
In this illustrated example, an outer boundary of the unfixed space 200A of the pocket 200 is defined by an attached perimeter where the outward facing surface 102BO of the first upper component 102B is bonded to the inward facing surface 102CI of the second upper component 102C. In some examples, 100% of this attached perimeter will be formed in a sewn seam-free manner (i.e., without any sewing or stitching). This outer boundary of the unfixed space 200A of the pocket 200 may include: (i) a top edge 200TE, (ii) a bottom edge 200BE, and (iii) a forward edge 200FE extending between the top edge 200TE and the bottom edge 200BE and located on an opposite side of the pocket 200 from the slit 200S. Note
While not shown in
The combined first upper component 102B, second upper component 102C, and three-dimensional blank 904 (also called “upper preform” 902 herein) then is mounted on a support plate 810 for pressing by press plate 812. See arrow C in
Due to the presence of the three-dimensional blank 904, however, a portion of the inward facing surface 102CI of the second upper component 102C does not bond to the outward facing surface 102BO of the first upper component 102B (shown by dot-dash lines in
Aspects of this technology may be advantageous in several ways. For example, some aspects of this technology may be advantageous because they allow a user accessible pocket 200 to be formed in a footwear upper 102 in an easy manner using only the main structural components of the upper 102 (e.g., without adding separate pocket components to an existing upper construction). Additionally or alternatively, the pocket 200 can be easily formed in existing upper production processes with minimal additional processing steps and/processing time (e.g., without the need for a separate step of sewing a pocket into or onto an upper structure). Additionally or alternatively, in at least some examples of this technology, the upper pocket 200 is formed in a non-obtrusive location (e.g., at the rear, lateral heel area of the upper) and/or with a minimalist or streamlined profile or exterior footprint on the upper 102. Thus, the pocket 200 (and any electronic module 210 or other component placed therein) is located in an “out-of-the-way” location, may not be readily visible to the wearer, and/or will be unlikely to affect athletic performance (e.g., unlikely to contact the ball during play).
The present technology is disclosed above and in the accompanying drawings with reference to a variety of embodiments. The purpose served by the disclosure, however, is to provide an example of the various features and concepts related to the technology, not to limit its scope. One skilled in the relevant art will recognize that numerous variations and modifications may be made to the embodiments described above without departing from the scope of the present invention, as defined by the appended claims.
