Methods of forming uppers of articles of footwear and methods of making articles of footwear

This application claims priority based on: (a) U.S. Provisional Patent Application No. 62/655,519, filed on April 10, 2018, and (b) U.S. Provisional Patent Application No., filed on April 10, 2018 62/655,539. US Provisional Patent Application No. 62/655,519 and US Provisional Patent Application No. 62/655,539 are each incorporated herein by reference in their entirety.

The present invention relates to the field of footwear and other foot-containing devices. In particular, aspects of the invention relate to uppers for use in articles of footwear and other foot-receiving devices and methods of making the same.

The traditional sports shoe object consists of two main components, the upper and the sole structure. The upper provides foot coverage, securely accommodates and positions the foot relative to the sole structure. Additionally, the upper may be configured to protect the foot and provide ventilation, thereby cooling the foot and removing sweat. The sole structure is secured to the bottom surface of the upper and is generally disposed between the foot and any contact surface. In addition to attenuating ground forces and absorbing energy, the sole structure provides traction and controls potentially harmful foot movements such as overpronation. The general characteristics and configuration of the upper and sole structures are discussed in more detail below.

The upper creates a space inside the shoe to accommodate the foot. This space has the general shape of the foot, and access to this space is provided at the ankle or foot insertion opening. Accordingly, the upper extends over the instep and toe area of the foot, to the inside and outside of the foot, and surrounds the heel area of the foot. Lacing systems are often incorporated into the upper to selectively change the size of the ankle opening and allow the wearer to alter certain dimensions of the upper, particularly the circumference, to accommodate different proportions of the foot. Additionally, the upper may include a tongue that extends beneath the lacing system to enhance wearer comfort (e.g., modulate the pressure exerted by the laces on the foot), and the upper may also include a heel tab. counter) to limit or control the movement of the heel.

The sole structure generally combines multiple layers, which are traditionally called "insole", "midsole", and "outsole". An insole (which may also constitute a sock liner) is a thin member located within the upper of a shoe next to the plantar (lower) surface of the foot to enhance the comfort of the shoe, such as to wick away moisture. The midsole, which is traditionally attached to the upper along its entire length, forms the middle layer of the sole structure and serves many purposes, including controlling foot movement and attenuating impact forces. The outsole forms the ground-contacting element of the shoe and is usually made of a durable, abrasion-resistant material and contains textures or other features to improve traction. Terminology/General Information

First, some general terms and information are provided to assist in understanding this specification and the various aspects of the invention described herein. As noted above, the present invention relates to the field of footwear and other foot-containing devices. "Foot-receiving device" means any device into which a user places at least some portion of his or her foot. In addition to all types of footwear (described below), foot-retaining devices include, but are not limited to: bindings for securing the foot in snow skis, cross-country skis, wakeboards, snowboards, and the like, and Other devices; bindings, clips, or other devices for securing feet to pedals used with bicycles, sports equipment, and the like; bindings, clips, or other devices for accommodating feet during play of video games or other games, Magazines, or other devices; and the like. A "foot-retaining device" may include one or more "foot coverings" (e.g., shoe-like upper components) that help position the foot relative to other components or structures, and one or more A "foot support" (e.g., a shoe-like sole structural component) that supports at least some portion of the plantar surface of a user's foot. A "fixation system" may assist in positioning and/or securely retaining a user's foot relative to the foot covering and/or foot support. "Footwear" means any type of clothing for the foot and this term includes, but is not limited to: all types of shoes, boots, sneakers, sandals, flip-flops, flip-flops, mules , slippers (scuffs and slippers), sports-specific shoes (such as cross-country shoes, golf shoes, tennis shoes, baseball shoes, football cleats, ski boots, basketball shoes, cross-training shoes, track and field shoes, track and field shoes (for example, for High jump, triple jump, etc.), etc.), and the like. "Foot support" may include components used in articles of footwear that are used and/or function as midsoles and/or outsoles (or components that provide corresponding functions in non-shoe type foot support devices).

As used herein, the term "anterior" or "anterior direction" means, unless the context otherwise requires or indicates, a direction toward or toward the anteriormost toe area of a footwear or foot-receiving device structure or component. .

Filamentous structures configured in more sinuous and/or serpentine patterns and/or diamond or parallelogram shapes can provide directional stretch characteristics (eg, more stretch in one direction than an opposite direction). Closer spacing of filamentous structures within one or more layers and/or an individual layer tends to provide that layer and/or zone with less elasticity, less stretch, less permeability (e.g., to air, water, or other materials) and/or less breathable (and larger filament spacing tends to increase these properties for that layer and/or zone).

In view of the above background and general description of aspects and examples of the present invention, the following sets forth specific examples of uppers, upper components, upper blanks, and/or articles of footwear in accordance with at least some examples of the present invention. Detailed description. II. Detailed description of specific examples of uppers, upper components, upper blanks, and articles of footwear according to the present invention

Figure 1 illustrates an upper blank 1000 for forming an upper of an article of footwear (or a foot covering component for another foot receiving device) according to one example of the present invention. The shoe upper blank material 1000 of this example is formed from a multi-layer extruded filamentary structure. One or more of the filamentary construction layers of upper blank 1000 (and optionally each individual layer of filamentary construction layers) may be extruded into a continuous path of extruded filamentary construction, although in the present invention In some examples one or more (or even all) of the individual layers need not be extruded into a continuous path. The paths of the extruded filamentous structures in any one or more of the layers of upper blank 1000 may extend to form one or more (and optionally all) of the following: Lateral rear heel portion 1002 (e.g., The outer side 1002s of the ankle/foot opening 1014 of the upper blank 1000, the lateral midfoot 1004 (such as next to the outer side 1004s of the instep opening 1012 of the upper blank 1000) may include one or more structures to engage the shoe. belt), the forefoot portion 1006 (for example, it bridges the outer side to the inner side of the upper blank material 1000, the front of the forefoot), the inner midfoot portion 1008 (for example, next to the inner side 1008s of the instep opening 1012 of the upper blank material 1000, It may include one or more structures to engage the laces), and the medial rear heel portion 1010 (eg, the medial side 1010s of the ankle/foot opening 1014 of the upper blank 1000). The vertical dashed lines shown in Figure 1 generally define and divide upper blank 1000 into three portions or regions: (a) rear third (containing lateral rear heel portion 1002 and medial rear heel portion 1010) , (b) the middle third (including the lateral midfoot 1004 and the medial midfoot 1008), and (c) the anterior third (including the forefoot 1006). In some examples of the present invention, the shoe upper blank 1000 is mainly composed of or even composed of multi-layer filamentary structural structures. For this exemplary shoe upper blank 1000 , the white space visible in FIG. 1 constitutes the open space between the path segments of the filamentous structure (eg, where the shoe upper blank 1000 can be completely seen through).

Exemplary features of individual layers of the exemplary multi-layer shoe upper blank 1000 will be described in more detail in conjunction with FIGS. 2A to 2F . 2A and 2D generally illustrate an extruded path segment 100 that may be laid down by an extruder 102 during an upper forming process (eg, a solid deposition molding or fusion deposition molding process) according to some examples of the present invention. As shown in these figures, an individual path segment 100 of an extruded filamentary structure will generally have an axial length L that is much greater than the width and/or thickness T of the path segment of the individual filamentary structure. As some more specific examples, an individual filamentous construct (and/or at least one or more path segments 100 thereof) may have an extrusion thickness dimension T of less than 3 mm thick, and in some examples, less than Less than 2 mm thick, less than 1.5 mm thick, less than 1 mm thick, or less than 0.75 mm thick, or even less than 0.5 mm thick. The width dimension W can be much larger than the thickness dimension T for at least some path segments 100 (and optionally all path segments 100 in an upper layer and/or upper blank 1000). The path segment length dimension L and/or the overall continuous path length can be at least 10 times (and in some examples at least 20 times larger) than the width dimension and/or thickness dimension T of the filamentary structure/path of the filamentary structure. at least 50 times greater, at least 70 times greater, at least 100 times greater, or even at least 150 times greater). Also, as noted above, an individual layer of an upper component may contain a plurality of non-intersecting spaced path segments. As some further examples, as shown in the figure, an individual layer may include at least 5 non-intersecting path segments over a path segment length of at least 25 mm, and in some examples, at least 50 mm, at least 70 mm, at least A path segment length of 100 mm, at least 150 mm, or even greater contains at least 5 non-intersecting path segments. As an additional example, an individual layer may contain at least 15 non-intersecting path segments on any of the above-mentioned path segment length dimensions, or may even contain at least 20 non-intersecting path segments on any of the above-mentioned path segment length dimensions.

As shown in Figure 2D, the material 108 used to form the filamentally constructed path segment 100 may be forced through the nozzle 104 of the extruder 102 onto a substrate 106, which may be formed of glass or other suitable material. The nozzle 104 diameter may be somewhat narrower than the final extrusion width W of the path segment 100 , for example because the heated filamentous construction material 108 tends to flatten after being deposited as the path segment 100 (or may even be blocked by the extruder 102 nozzle 104 push down). Generally speaking, increasing the temperature of the extruded material 108 results in the deposited path segment 100 being flatter (and generally increasing the width W and decreasing the thickness T). In another example, the nozzle 104 diameter may be approximately 0.4 mm, although the nozzle 104 diameter may range, for example, from 0.25 mm to 2.5 mm (and in some examples, from 0.3 mm to 2 mm). The surface 106s of the substrate 106 may be smooth or otherwise textured, and the features of the bottom surface 100s of the filamentally structured path segment 100 may be formed and take on the shape (e.g., smooth or textured) of the surface 106s of the substrate 106 with which it contacts and is formed. characteristics).

FIG. 2B illustrates a portion of a shoe upper blank 1000 in which two layers of filamentous structures exist. First, a path segment 100 of a first filamentary structure (such as having any one or more of the filamentary structure dimensions and/or structural features described above) is extruded, and then the path segments 100 of the first filamentary structure are intersected or intersected. The path segment 200 of the second filamentous structure is extruded in the direction (eg, as the second layer of the upper/upper blank 1000). The path segment 200 of the second filamentary construct may directly contact the path segment 100 of the first filamentary construct (at contact area 202 ) when extruded. Heat from the path segment 200 of the second filamentary structure during its extrusion (and/or another heat source) causes the path segment 200 of the second filamentary structure to separate from the path segment 100 of the first filamentary structure. The contact areas 202 in contact with each other are fused together (e.g., the material of the path segment 200 of the second filamentary structure can be aggregated and seamlessly connected with the material of the path segment 100 of the first filamentary structure, and in the path of the second filamentary structure This fusion feature may be supported by heat from the extruded path segment 200 of the second filamentary structure while the segment 200 is being deposited). In this way, the first layer of the shoe upper blank material 1000 (including the path segment 100 of the first filamentous structure) can be fixedly connected to the second layer of the shoe upper blank material 1000 (including the path segment 100 of the first filament structure) at the contact area 202 in an adhesive-free manner. Path segment 200) of the second filamentary structure.

Figures 2C and 2E show another way in which two (or more) layers of upper blank 1000 can be joined to each other. Instead of simply intersecting (as shown in FIG. 2B ), the second filamentally constructed path segment 200 may be extruded substantially in line with the first filamentously constructed path segment 100 over at least a portion of its respective axial length L. Overlapping (and optionally extending parallel) locations. This action creates an axially extending contact area 202 between path segments 200 and 100 . Although other options are possible, after extruding the path segment 100 of the first filamentary structure, a path segment of the second filamentary structure may be extruded at a location slightly offset from the extrusion path of the path segment 100 of the first filamentary structure. 200 (optionally formed in the second layer of upper blank 1000). As shown in Figure 2E, when extruding the first filamentally structured path segment 100, the nozzle 104 is centered on line 120a. Next, when extruding the path segment 200 of the second filamentary structure (eg, with a second upper blank layer), the nozzle 104 is displaced an offset distance D to be centered on the line 120b. This offset distance D can be any desired amount, and in some examples of the invention can be between 0.5 DN and 0.9 DN, and in some examples between 0.625 DN and 0.85 DN, or even about 0.75 DN, where DN represents the nozzle 104 diameter.

Overlapping (and substantially parallel) contact areas 202 of the type shown in Figures 2C and 2E can extend for any desired axial length L without departing from the invention. In some examples, the second filamentous construct (or The path segments 200 of the second filamentary structure of the second layer) may extend parallel to and/or partially overlap the path segments 100 of the first filamentary structure (or first layer). The overlapping contact area 202 may also be a curved path segment. Additionally or alternatively, the overall layer path of the second layer (including the path segment 200 of the second filamentous structure): (a) may be at least 10%, at least 25%, at least 50%, At least 75%, at least 85%, at least 90%, or even at least 95% extends parallel to and/or partially overlaps the entire layer path of the first layer (including the path segment 100 of the first filamentous structure) and/or (b ) may be at least 10%, at least 25%, at least 50%, at least 75%, at least 85%, at least 90%, or even at least 95% of the overall layer paths of the first layer ( The path segments 100) including the first filamentous structures extend parallel and/or partially overlap.

In at least some examples of this aspect of the invention, the path segment 200 of the second filamentary structure overlaps the path segment 100 of the first filamentary structure by an overlap width WO that is from the second filamentary structure in the overlapping position. and 5% to 50% of the overall bonding width WC of the first filamentous structure. See Figure 2C. In some examples, this overlap width WO may be from 10% to 45% or even 15% to 40% of the overall combined width WC at the overlap location. When individual filamentous structures are layered into a plurality of non-intersecting spaced path segments, a second plurality of non-intersecting spaced path segments of the second filamentary structure (eg, path segments 200) can be combined with a first plurality of non-intersecting spaced path segments of the first filamentary structure. A plurality of non-intersecting spaced path segments (e.g., path segment 100) overlap by an overlap width WO, which is from (a) a second plurality of non-intersecting spaced path segments and (b) a first plurality of non-intersecting spaced path segments at the overlapping path segment locations 5% to 50% of the overall bonding width WC (or from 10% to 45% or even from 15% to 40%). Additionally or alternatively, if desired, the overlapping width WO of one or more of the path segments 200 of the second filamentary structure and the corresponding path segment 100 of the first filamentary structure may be at a second of the overlapping positions. Within 10% to 75%, within 15% to 60%, or even between 25% and 50% of the width W of the path segment 200 of the filamentary structure (or the width W of the path segment 100 of the first filamentary structure) within. So, WO = 0.1W to 0.75W, or even 0.15W to 0.6W or 0.25W to 0.5W, where W is the width of the path segment 100 or 200.

Although FIGS. 2C and 2E show two overlapping layers of path segments 100 and 200 , if desired, a third layer and/or additional layers may be deposited between the path segments 100 of the first filamentary structure and the path segments 100 of the second filamentary structure. The overlapping portion or the adjacent portion of the path segment 200 overlaps the path segment 100 of the first filament structure and/or the path segment 200 of the second filament structure. This feature is shown in Figures 2C and 2E as a path segment 250 of the layer in the form of a dotted line. The third layer path segment 250 may overlap the first layer path segment 100 and/or the second layer path segment 200 in any of the overlapping width and/or length ranges described above. Overlapping and substantially parallel path segments, such as each of path segments 100, 200, and/or 250 shown in Figures 2C and 2E, may have the same or different colors. In some examples, two or more overlapping and substantially parallel path segments may have the same general color but different hues of that color. These color features can, if desired, contribute interesting aesthetic features to the upper components.

2F illustrates additional path segments and/or path layer features that may be provided in at least some upper blanks 1000 and/or uppers in accordance with aspects of the present invention. As described above, one or more filamentous structural layers of the upper or upper blank 1000 may be formed by the extruder 102 (optionally into a continuous path). The path of this filamentary structure may form the upper, layer, and/or one of the lateral heel, lateral midfoot, forefoot, medial midfoot, and/or medial heel of the upper blank 1000 one or more. In fabricating these portions of the upper/upper blank 1000 from thin extruded filamentary structures, in some areas of the upper/upper blank 1000 , individual layers of path segments 100 may be extruded to be opposite each other. Close positions, optionally extending parallel. As shown in Figure 2F, in one layer, the filamentous constructs can be extruded into a plurality of non-intersecting spaced paths including at least 3 first non-intersecting path segments (path segments 100a-100e shown in Figure 2F) part. In this illustrative example, each non-intersecting path segment of a group of non-intersecting path segments of an individual layer (path segments 100a to 100e) is separated from each directly adjacent non-intersecting path segment in the same layer by a length dimension L of at least 25 mm. The upper phases are separated by less than 10 mm (S1 to S4 in Figure 2F). In some examples, the spacing S can be less than 8 mm, less than 6 mm, less than 5 mm, or even less than 3 mm and/or the length dimension L can be at least 15 mm, at least 50 mm, at least 75 mm, at least 100 mm, or even at least 150 mm. Widths W1 through W5 of path segments 100a through 100e, respectively, as shown in Figure 2F, may have any of the width characteristics described above (as described in conjunction with Figures 2A and 2D). In some examples of the present invention, a second layer (or even a third or more layer) of path segments is deposited that overlaps and/or is parallel to the path segments 100a-100e shown in Figure 2F, such as in Figures 2C and Overlap as shown in 2E.

The spacing S, the width dimension W, and/or the overlap length dimension L within a given layer may be constant or vary throughout the layer of path segments. As some more specific examples, a filamentous structure (and optionally a continuous path of filamentary structures) in one layer may have a first thickness in a first region of the upper or upper blank 1000 and in a first region of the upper or upper blank 1000 . The second region of the face blank 1000 has a second thickness, wherein the first thickness is different from the second thickness (and optionally can be within the range described above). Additionally or alternatively, if desired, the filamentous formations in one layer (and optionally a continuous path of filamentary formations) may have a first diameter and/or a first region of the upper or upper blank 1000 a first width and a second diameter and/or a second width in a second region of the upper or upper blank 1000, wherein the first diameter and/or first width is different from the second diameter and/or second width ( and optionally within the above range). Different thicknesses, widths, and/or diameters of the filamentous structures within a layer can help control the properties of the upper/upper blank 1000 (such as strength, durability, flexibility, stretch, breathability, support, etc. ).

Various features and examples of an upper or upper blank 1000 (eg, similar to that shown in FIG. 1 ) made from multiple layers of filamentary structural materials, as well as methods of making the same, will be described in more detail below in connection with FIGS. 3A to 3W . FIG. 3A shows a first portion of an exemplary first layer 300 formed, for example, through a solid deposition modeling process by extruding a first material into a plurality of path segments, such as any of the path and/or path segment characteristics described above. Filamentous structures (such as any having the characteristics and properties of filamentous structures described above). Optionally, this first layer 300 can be extruded into a first continuous path. In this illustrative example, the first path (optionally a continuous path) of the first filamentous structure forms the following portions of the first layer 300: (a) the first lateral rear heel portion 302 (eg, and/or or next to the lateral 302s of the ankle/foot opening 314 of the first layer 300), (b) the first lateral midfoot 304 (such as with and/or next to the lateral 304s of the instep opening 312 of the first layer 300 (or (next to the inner edge), (c) first forefoot 306 (as it bridges from the lateral to medial side of first layer 300, in front of the midfoot), (d) first medial midfoot 308 (as with and/or or next to the inner side 308s (or inner edge) of the instep opening 312 of the first layer 300), and (e) the first inner rear heel portion 310 (such as with and/or at the ankle/foot of the first layer 300 (beside 310s inside opening 314). The vertical dotted lines shown in Figure 3A generally define and divide the first layer 300 into three parts: (a) the posterior third (including the lateral rear heel portion 302 and the medial rear heel portion 310), (b) the middle third one third (including the lateral midfoot 304 and the medial midfoot 308), and (c) the anterior third (including the forefoot 306). In at least some examples of the present invention, the first layer 300 is composed primarily of or even the filamentous structural structure (optionally formed as a continuous path and/or a monolithic structure). The white space visible in Figure 3A for this exemplary first layer 300 constitutes the open space between the path segments of the filamentous structure (eg, where the first layer 300 is fully visible).

While the path segments of first layer 300 may be extruded in any desired order without departing from the invention, in some examples of the invention, the perimeter (e.g., 300P) may be extruded first, and the remainder of first layer 300 may be extruded next. Partially, for example, in a "raster" manner, to fill the area within the surrounding 300P. In the illustrated example, the extruded overall path of the first layer 300 lays out a first filamentous structure as a first plurality of non-intersecting spaced path segments over a majority of the entire surface area of the first layer 300, with the first layer 300 essentially extends in a medial-lateral direction. This medial-lateral oriented and/or extended filament structure can help increase the "lock-in" effect of the upper (i.e. help secure the foot securely to the sole structure) and help control/reduce stretch . With the lateral rear heel portion 302 and the medial rear heel portion 310, the path segment of the first filamentous structure extends generally from the ankle opening 302s/310s to the bottom peripheral portion 302t/310t of the first layer 300 (such as the first layer 300 connects the sole structure of the final article of footwear structure), wherein adjacent path segments of the first layer 300 extend substantially parallel. Similarly, with the lateral midfoot portion 304 and the medial midfoot portion 308, the path segment of the first filamentous structure extends generally from the inner edge 304s/308s of the instep opening 312 to the bottom peripheral portion 304t/308t of the first layer 300. (Outer edge) (eg, where the first layer 300 connects to the sole structure of the final article of footwear structure), where adjacent path segments of the first layer 300 extend substantially parallel. In the forefoot region 306, a path segment of the first filamentous structure extends generally from the lateral bottom edge 306s of the first layer 300 to the medial bottom edge 306t (as where the first layer 300 connects to the sole structure of the final article of footwear structure) , wherein adjacent path segments of the first layer 300 extend substantially parallel. The path segments in these various regions 302, 304, 306, 308, 310 may have any of the features and/or options previously described for the path segments shown in Figures 2A-2F.

In the first layer 300, path segments in one area need not be at constant spacing from directly adjacent path segments in other areas of the first layer 300. For example, as shown in FIG. 3A , the plurality of non-intersecting spaced path segments in the forefoot 306 and/or midfoot 304/308 of the first layer 300 is larger than the plurality of non-intersecting spaced path segments in the heel 302/310 of the first layer 300. non-intersecting path segments are more closely spaced. Path segment spacing (e.g., S1 through S4 from Figure 2E) may be selected to provide desired characteristics (e.g., desired stretchability, breathability, etc.) of individual areas of first layer 300, upper, and/or upper blank 1000. etc).

After extruding the first layer 300 (eg, onto the substrate 106), a second layer 350 of the integral upper or upper blank 1000 may then be applied to the first layer 300. Figure 3B shows individual path segments of this exemplary second layer 350, and Figure 3C schematically shows the production of the second layer 350 onto the previously prepared first layer 300 to create a bonded upper or upper blank 1000. 380 for the first and second floors. Specifically, FIG. 3B shows that a second filamentous structure (such as any having the characteristics and characteristics of the above-described filamentary structure) is formed, for example, through a solid deposition modeling process and by extruding the second material into a plurality of path segments. (e.g., having any of the path and/or path segment characteristics described above). Optionally, this second layer 350 can be extruded into a second continuous path. In this illustrative example, the second path (optionally a continuous path) of the second filamentous structure forms the following portions of the second layer 350: (a) the second lateral rear heel portion 352 (eg, and/or or next to the lateral 352s of the ankle/foot opening 364 of the second layer 350), (b) the second lateral midfoot 354 (such as with and/or next to the lateral 354s of the instep opening 362 of the second layer 350 (or (next to the inner edge), (c) second forefoot portion 356 (as it bridges from the lateral to medial side of second layer 350, in front of the midfoot), (d) second medial midfoot portion 358 (as with and/or or next to the medial 358s (or inner edge) of the instep opening 362 of the second layer 350), and (e) the second medial rear heel portion 360 (such as with and/or at the ankle/foot of the second layer 350 (beside 360s inside opening 364). The vertical dashed lines shown in Figure 3B generally define and divide the second layer 350 into three parts: (a) the posterior third (including the lateral rear heel portion 352 and the medial rear heel portion 360), (b) the middle third one third (including the lateral midfoot portion 354 and the medial midfoot portion 358), and (c) the anterior third (including the forefoot portion 356). In at least some examples of the present invention, the second layer 350 is composed primarily of or even the filamentous structural structure (optionally formed as a continuous path and/or a monolithic structure). The white spaces visible in Figure 3B for the second layer 350 for this example constitute the open spaces between the path segments of the filamentary structure (eg, where the second layer 350 is fully visible).

While the path segments of second layer 350 may be extruded in any desired order without departing from the invention, in some examples of the invention, the perimeter (e.g., 350P) may be extruded first, and the remainder of layer 350 may be extruded next, For example, use a method similar to "raster" to fill the surrounding area within 350P. In the illustrated example, the extruded overall path of the second layer 350 lays out the second filamentous structure as a second plurality of non-intersecting spaced path segments over a majority of the entire surface area of the second layer 350, with the second layer 350 extends in a substantially medial-lateral direction (eg, to help provide the "locking" or other features described above for first layer 300). With the lateral rear heel portion 352 and the medial rear heel portion 360, the path segment of the second filamentous structure extends generally from the ankle opening 352s/360s to the bottom peripheral portion 352t/360t of the second layer 350 (such as the second layer 350 connects the sole structure of the final article of footwear structure), wherein adjacent path segments of layer 350 extend substantially parallel. Similarly, with the lateral midfoot portion 354 and the medial midfoot portion 358, the path segment of the second filamentous structure extends generally from the inner edge 354s/358s of the instep opening 362 to the bottom peripheral portion 354t/358t of the second layer 350. (Outer edge) (eg, where second layer 350 joins the sole structure of the final article of footwear structure), where adjacent path segments of layer 350 extend substantially parallel. In the forefoot region 356, the path segment of the second filamentous structure extends generally from the lateral bottom edge 356s of the second layer 350 to the medial bottom edge 356t (as where the second layer 350 connects to the sole structure of the final article of footwear structure) , wherein adjacent path segments of the layer 350 extend substantially parallel. The path segments in these various regions 352, 354, 356, 358, 350 may have any of the features and/or options previously described for the path segments shown in Figures 2A-2F.

In the second layer 350, path segments in one area need not be at constant spacing from directly adjacent path segments in other areas of the second layer 350. For example, as shown in FIG. 3B , the plurality of non-intersecting spaced path segments in the forefoot 356 and/or midfoot 354/358 of the second layer 350 is larger than the plurality of non-intersecting spaced path segments in the heel 352/360 of the second layer 350. non-intersecting path segments are more closely spaced. Path segment spacing (e.g., S1 through S4 from Figure 2E) may be selected to provide desired characteristics (e.g., desired stretchability, breathability, etc.) of individual areas of layer 350, upper, and/or upper blank 1000 ).

As is apparent from a comparison of Figures 3A and 3B, the path segments of the first layer 300 and the second layer 350 extend in a generally parallel manner over a substantial portion of their overall paths. Accordingly, the path segments of the second layer 350 may be extruded generally parallel to and/or overlapping the path segments of the first layer 300 over their entire path length in the manner illustrated in Figures 2C and 2E. If desired: (a) at least 25% (and in some examples, at least 40%, at least 50%, at least 60%, at least 75%, at least 85%, or even at least 90%) of the overall path length of the second layer 350 %) overlap with path segments of the first layer 300 in the manner illustrated in Figures 2C and 2E and/or (b) at least 25% (and in some examples, at least 40%, At least 50%, at least 60%, at least 75%, at least 85%, or even at least 90%) overlaps the path segments of the second layer 350 in the manner shown in Figures 2C and 2E. Therefore, when the second layer 350 is extruded, the filamentous structures of the second layer 350 will directly contact the filamentary structures of the first layer 300 (at the overlapping contact area 202). Heat from the second layer 350 (and/or another heat source) as it is extruded causes the path segments of the second filamentary structure and the path segment 100 of the first filamentary structure to contact each other in the contact region 202 fused together (eg, the filamentary construction material of the second layer 350 can be polymerized and seamlessly connected to the filamentary construction material of the first layer 300). In this manner, the first layer 300 of the shoe upper or shoe upper blank 1000 can be fixedly connected to the second layer 350 of the shoe upper or shoe upper blank 1000 at the contact area 202 in an adhesive-free manner to form the shoe upper or shoe upper blank 1000 as shown in FIG. 3C Combine the first and second layers 380. A single structure is formed by combining the upper components or mid-materials of the first and second layers 380, wherein the first layer 300 and the second layer 350 are fixed together in a non-adhesive fusion manner. The upper component or midsole that includes the combined first and second layers 380 may be composed primarily of, or even consist of, the first layer 300 and the second layer 350 .

After extruding the second layer 350 (eg, onto the first layer 300 and/or the substrate 106 ), a third layer 400 of the integral upper or upper blank 1000 may then be applied to the bonded first and second layers. 380. Figure 3D shows individual path segments of this exemplary third layer 400, and Figure 3E schematically shows the production of the third layer 400 onto the previously prepared bonded first and second layers 380 to create a shoe upper or upper Bonded first to third layers 440 of blank 1000 . Specifically, FIG. 3D shows that, for example, through a solid deposition modeling process, a third filamentous structure (such as any one having the characteristics and characteristics of the above-described filamentary structure) is formed and formed into a plurality of path segments by extruding the third material. (e.g., having any of the path and/or path segment characteristics described above). Optionally, this third layer 400 can be extruded into a third continuous path. In this illustrative example, a third path (optionally a continuous path) of the third filamentous structure forms the following portions of the third layer 400: (a) a third lateral rear heel portion 402 (eg, and/or or next to the lateral 402s of the ankle/foot opening 414 of the third layer 400), (b) the third lateral midfoot 404 (such as with and/or next to the lateral 404s of the instep opening 412 of the third layer 400 (or (next to the inner edge), (c) third forefoot 406 (as it bridges from the lateral to medial side of third layer 350, in front of the midfoot), (d) second medial midfoot 408 (as with and/or or next to the medial 408s (or inner edge) of the instep opening 412 of the third layer 400), and (e) the third medial rear heel portion 410 (such as with and/or at the ankle/foot of the third layer 400 (beside 410s inside opening 414). The vertical dotted lines shown in Figure 3D generally define and divide the third layer 400 into three parts: (a) the posterior third (including the lateral rear heel portion 402 and the medial rear heel portion 410), (b) the middle third one third (including the lateral midfoot 404 and the medial midfoot 408), and (c) the anterior third (including the forefoot 406). In at least some examples of the present invention, the third layer 400 is composed primarily of or even the filamentous structural structure (optionally formed as a continuous path and/or a monolithic structure). The white space visible in Figure 3B for this exemplary third layer 400 constitutes the open space between the path segments of the filamentary structure (eg, where the third layer 400 is fully visible).

While the path segments of third layer 400 may be extruded in any desired order without departing from the invention, in some examples of the invention, the perimeter (eg, 400P) may be extruded first, and the remainder of layer 400 may be extruded next, For example, use a "raster" method to fill the surrounding area within 400P. In the illustrated example, the extruded overall path of the third layer 400 lays out the second filamentous structure as a third plurality of non-intersecting spaced path segments over a majority of the entire surface area of the second layer 350, with the third layer The 400 essentially extends in the front-to-back direction. As shown in FIG. 3D , the third plurality of non-intersecting path segments of the third layer 400 are gently curved in the lateral rear heel 402 , lateral midfoot 404 , forefoot 406 , and medial rear heel 410 . The way extends forward from the rear heel portion 402/410. However, in the medial midfoot 408, at least some of the third plurality of non-intersecting path segments extend in a serpentine configuration including at least two peaks (408P) and at least two valleys (408V). The path segments in these various regions 402, 404, 406, 408, 410 may have any of the features and/or options previously described for the path segments shown in Figures 2A-2F.

As further shown in Figure 3D, the third path of the filamentous structure is defined at a first inner edge of the lateral instep opening edge 404s, at a first outer edge 404t of the lateral midfoot region 404, and at a second inner edge of the medial instep opening edge 408s. edge, and a second outer edge 408t of the medial midfoot region 408. An instep opening 412 of the third layer 400 is defined between a first inner edge at 404s and a second inner edge at 408s. The third path of the filamentary structure in this exemplary third layer 400 includes: (a) a first plurality of non-intersecting spaced path segments located between the first inner edge 404s and the first outer edge 404t, wherein The first plurality of non-intersecting spaced path segments of the three paths are linear and/or curved without defining peaks and valleys and/or (b) a second plurality of non-intersecting spaced path segments located between the second inner edge 408s and the second outer edge 408t A plurality of non-intersecting spaced path segments, wherein the second plurality of non-intersecting spaced path segments located in the third continuous path between the second inner edge at 408s and the second outer edge 408t are arranged in a serpentine shape Extends and has at least two peaks 408P and at least two valleys 408V. The third layer 400 of Figure 3D may include at least 4 path segments, at least 6 path segments, at least 8 path segments, at least 10 path segments, or even at least 4 path segments extending substantially parallel and/or having the serpentine configuration. 12 path segments.

In the third layer 400, path segments in one area need not be at constant spacing from directly adjacent path segments in other areas of the third layer 400. For example, as shown in Figure 3D, the plurality of non-intersecting spaced path segments in the front foot 406 of the third layer 400 are more closely spaced than the plurality of non-intersecting spaced path segments in the mid-foot 404/408, and/or The plurality of non-intersecting spaced path segments in the forefoot 406 and/or midfoot 404/408 of the third layer 400 are more closely spaced than the plurality of non-intersecting spaced path segments in the heel 402/410 of the third layer 400. interval.

As is apparent from a comparison of Figure 3D with Figures 3A and 3B, the path segments of the third layer 400 will substantially intersect the path segments of the first layer 300 and the second layer 350 over a substantial portion of their overall paths. The intersecting path segments form a grid or generally matrix pattern, as can be seen in the joined first through third layers 440 shown in Figure 3E. The path segments of the third layer 400 may intersect the path segments of the first layer 300 and/or the second layer 350 at any desired angle, such as from 5° to 175°, and in some examples, from 15° to 165°. , from 25° to 155°, from 35° to 145°, from 45° to 135°, from 55° to 125°, from 60° to 120°, from 65° to 95° and so on. In at least some examples of the invention: (a) the third path of the third layer 400 is less than 50% (and in some examples, less than 40%, less than 30%, less (b) the third path of the third layer 400 is less than 50% of the overall length of the third path (and in some cases In the example, less than 40%, less than 30%, less than 20%, or even less than 10%) overlaps with the second path of the second layer 350, (c) the third path of the third layer 400 is on the A path that overlaps less than 50% (and in some examples, less than 40%, less than 30%, less than 20%, or even less than 10%) of the entire length of the first path of the first layer 300 , and/or (d) the third path of the third layer 400 is less than 50% (and in some examples, less than 40%, less than 30%, less than 20%, or less than 20%) of the overall length of the second path. Even less than 10%) overlaps with the second path of the second layer 350.

Therefore, when the third layer 400 is extruded, the filamentous structures of the third layer 400 will directly contact the filamentary structures of the first layer 300 and the filamentary structures of the second layer (at the intersecting contact area 202). Heat from the third layer 300 (and/or another heat source) as it is extruded causes path segments of the third filamentary structure to coincide with path segments of the first filamentary structure and/or paths of the second filamentary structure. The segments are fused together in the contact area 202 where the path segment of the third filamentary structure contacts one or both of the path segments of the first filamentary structure and/or the path segment of the second filamentary structure (such as the contact area 202 of the third layer 400 The filamentary structural material may be polymerized and seamlessly connected to the filamentary construction material of the first layer 300 and/or the second layer 350). In this way, the third layer 400 of the shoe upper or shoe upper blank material 1000 can be fixedly connected to the first layer 300 and the second layer 350 of the shoe upper or shoe upper blank material 1000 at the contact area 202 in an adhesive-free manner. Bonded first to third layers 440 are formed. The upper component or midsole including the combined first to third layers 440 forms a single structure, in which the first layer 300, the second layer 350, and the third layer 400 are fixed together in a non-adhesive fusion manner. The upper component or midsole including the combined first to third layers 440 may be primarily composed of or even composed of the first layer 300 , the second layer 350 , and the third layer 400 .

After extruding the third layer 400 (eg, onto the first layer 300, the second layer 350, and/or the substrate 106), a fourth layer 500 of the entire upper or upper blank 1000 may then be applied to the bonded 440 on the first to third floors. Figure 3F shows individual path segments of this exemplary fourth layer 500, and Figure 3G schematically shows the production of the fourth layer 500 onto the previously prepared bonded first to third layers 440 to create a shoe upper or upper Bonded first through fourth layers 540 of blank 1000 . Specifically, FIG. 3F shows that a fourth filamentous structure (such as any having the characteristics and characteristics of the above-described filamentary structure) is formed, for example, through a solid deposition modeling process and is formed into a plurality of path segments by extruding the fourth material. (e.g., having any of the path and/or path segment characteristics described above). Optionally, this fourth layer 500 can be extruded into a fourth continuous path. In this illustrative example, the fourth path (optionally a continuous path) of the fourth filamentous structure forms the following portions of the fourth layer 500: (a) the fourth lateral rear heel portion 502 (eg, and/or or next to the lateral 502s of the ankle/foot opening 514 of the fourth layer 500), (b) the fourth lateral midfoot 504 (such as with and/or lateral 504s of the instep opening 512 of the fourth layer 500 (or (next to the inner edge)), (c) fourth forefoot 506 (as it bridges from the lateral to medial side of fourth layer 500, in front of the midfoot), (d) fourth medial midfoot 508 (as with and/ or next to the inner side 508s (or inner edge) of the instep opening 512 of the fourth layer 500), and (e) the fourth inner rear heel portion 510 (such as with and/or at the ankle/foot of the fourth layer 500 (beside 510s on the inner side of opening 514). The vertical dashed lines shown in Figure 3F generally define and divide the fourth layer 500 into three parts: (a) the posterior third (including the lateral rear heel portion 502 and the medial rear heel portion 510), (b) the middle third one third (including the lateral midfoot 504 and the medial midfoot 508), and (c) the anterior third (including the forefoot 506). In at least some examples of the present invention, the fourth layer 500 is composed primarily of or even the filamentous structural structure (optionally formed as a continuous path and/or a monolithic structure). The white space visible in Figure 3F for this exemplary fourth layer 500 constitutes the open space between the path segments of the filamentary structure (eg, where the fourth layer 500 is fully visible).

While the path segments of the fourth layer 500 may be extruded in any desired order without departing from the invention, in some examples of the invention the perimeter (e.g. 500P) may be extruded first and the remainder of the fourth layer 500 may be extruded subsequently. Partially, for example, in a "raster"-like manner, to fill the surrounding area within 500P. In the illustrated example, the extruded overall path of the fourth layer 500 lays out a fourth filamentary structure as a fourth plurality of non-intersecting spaced path segments over a majority of the entire surface area of the third layer 400, with the fourth layer The 500 essentially extends front-to-back. As shown in FIG. 3F , in the lateral rear heel 502 , lateral midfoot 504 , forefoot 506 , and medial rear heel 510 , a fourth plurality of non-intersecting path segments lead from the rear foot in a gentle curve. The heel 502/510 extends forward. However, in the medial midfoot 508, at least some of the fourth plurality of non-intersecting path segments extend in a serpentine configuration including at least two peaks (508P) and at least two valleys (508V). The path segments in these various regions 502, 504, 506, 508, 510 may have any of the features and/or options previously described for the path segments shown in Figures 2A-2F.

As further shown in Figure 3F, the fourth path of the filamentous structure is defined at a first inner edge of the lateral instep opening edge 504s, at a first outer edge 504t of the lateral midfoot region 504, and at a second inner edge of the medial instep opening edge 508s. edge, and a second outer edge 508t in the medial midfoot region 508. An instep opening 512 of the fourth layer 500 is defined between a first inner edge at 504s and a second inner edge at 508s. The fourth path of the filamentary structure in this exemplary fourth layer 500 includes: (a) a first plurality of non-intersecting spaced path segments located between the first inner edge 504s and the first outer edge 504t, wherein The first plurality of non-intersecting spaced path segments of the four paths are linear and/or curved without defining peaks and valleys and/or (b) a second plurality of non-intersecting spaced path segments located between the second inner edge 508s and the second outer edge 508t A plurality of non-intersecting spaced path segments, wherein the second plurality of non-intersecting spaced path segments located in the fourth continuous path between the second inner edge at 508s and the second outer edge 508t are arranged in a serpentine shape Extends and has at least two peaks 508P and at least two valleys 508V. The fourth layer 500 of Figure 3F may include at least 4 path segments, at least 6 path segments, at least 8 path segments, at least 10 path segments, or even at least 4 path segments extending substantially parallel and/or having the serpentine configuration. 12 path segments.

It can be clearly seen from a comparison of FIG. 3D and FIG. 3F that the path segments of the third layer 400 and the fourth layer 500 extend in a substantially parallel manner over a large portion of their overall paths. Accordingly, the path segments of the fourth layer 500 may be extruded generally parallel to and/or overlap the path segments of the third layer 400 over a majority of their overall path lengths as shown in Figures 2C and 2E. If desired: (a) at least 25% (and in some examples, at least 40%, at least 50%, at least 60%, at least 75%, at least 85%, or even at least 90%) of the overall path length of the fourth layer 500 %) will overlap the path segments of the third layer 400 in a manner as shown in Figures 2C and 2E and/or (b) at least 25% (and in some examples, at least 40%) of the overall path length of the third layer 400 %, at least 50%, at least 60%, at least 75%, at least 85%, or even at least 90%) will overlap the path segments of the fourth layer 500 in a manner as shown in Figures 2C and 2E. In at least some examples of the invention: (b) the fourth path of the fourth layer 500 is less than 50% (and in some examples, less than 40%, less than 30%, less (b) the fourth path of the fourth layer 500 is less than 50% of the overall length of the fourth path (and in some cases In the example, less than 40%, less than 30%, less than 20%, or even less than 10%) overlaps with the second path of the second layer 350, (c) the fourth path of the fourth layer 500 is on the A path that overlaps less than 50% (and in some examples, less than 40%, less than 30%, less than 20%, or even less than 10%) of the entire length of the first path of the first layer 300 , and/or (d) the fourth path of the fourth layer 500 is less than 50% (and in some examples, less than 40%, less than 30%, less than 20%, or less than 50% of the overall length of the second path) Even less than 10%) overlaps with the second path of the second layer 350.

Therefore, when the fourth layer 500 is extruded, the filamentous structures of the fourth layer 500 will directly contact the filamentary structures of the third layer 400 (at the overlapping contact area 202). Heat from the fourth layer 500 (and/or another heat source) as it is extruded causes the path segments of the fourth filamentary structure and the path segments of the third filamentary structure to fuse at the contact region 202 where they contact each other. together (eg, the filamentary construction material of the fourth layer 500 can be polymerized and seamlessly connected to the filamentary construction material of the third layer 400). In this manner, the third layer 400 of the upper or upper blank 1000 may be fixedly connected to the fourth layer 500 of the upper or upper blank 1000 at the contact area 202 in an adhesive-free manner.

As is apparent from a comparison of Figure 3F with Figures 3A and 3B, the path segments of the fourth layer 500 will substantially intersect the path segments of the first layer 300 and the second layer 350 over a substantial portion of their overall paths. The intersecting path segments form a grid or generally matrix pattern, as can be seen from the bonded first through fourth layers 540 shown in Figure 3G. The path segments of the fourth layer 500 may intersect the path segments of the first layer 300 and/or the second layer 350 at any desired angle, such as from 5° to 175°, and in some examples, from 15° to 165°. , from 25° to 155°, from 35° to 145°, from 45° to 135°, from 55° to 125°, from 60° to 120°, from 65° to 95° and so on. Therefore, when the fourth layer 500 is extruded, the filamentous structures of the fourth layer 500 will directly contact the filamentary structures of the first layer 300 and the filamentary structures of the second layer (at the intersecting contact area 202). Heat from the fourth layer 500 (and/or another heat source) as it is extruded causes the path segments of the fourth filamentary structure to coincide with the path segments of the first filamentary structure and/or the path of the second filamentary structure. The segments are fused together in the contact area 202 where the path segment of the fourth filamentary structure contacts one or both of the path segments of the first filamentary structure and/or the path segment of the second filamentary structure (such as the fourth layer 500 The filamentary structural material may be polymerized and seamlessly connected to the filamentary construction material of the first layer 300 and/or the second layer 350).

In this way, the fourth layer 500 of the shoe upper or shoe upper blank material 1000 can be fixedly connected to the first layer 300 , the second layer 350 , 350 of the shoe upper or shoe upper blank material 1000 at the contact area 202 in an adhesive-free manner. and the third layer 400 to form the combined first to fourth layers 540. The upper components or mid-materials including the combined first to fourth layers 540 form a single structure, in which the first layer 300, the second layer 350, the third layer 400, and the fourth layer 500 are fused in a non-adhesive manner Fastened together. The upper component or mid-material including the combined first to fourth layers 540 may be mainly composed of or even composed of the first layer 300 , the second layer 350 , the third layer 400 , and the fourth layer 500 .

In the fourth layer 500, path segments in one area need not be at constant spacing from directly adjacent path segments in other areas of the fourth layer 500. For example, as shown in Figure 3F, the plurality of non-intersecting spaced path segments in the front foot 506 of the fourth layer 500 are more closely spaced than the plurality of non-intersecting spaced path segments in the mid-foot 504/508, and/or The plurality of non-intersecting spaced path segments in the forefoot 506 and/or midfoot 504/508 of the fourth layer 500 are more closely spaced than the plurality of non-intersecting spaced path segments in the heel 502/510 of the fourth layer 500. interval.

After the fourth layer 500 is extruded (eg, onto the first layer 300 , the second layer 350 , the third layer 400 and/or the substrate 106 ), the fifth layer 600 of the overall upper or upper blank 1000 may then be applied. to the combined first to fourth layers 540. Figure 3H shows individual path segments of this exemplary fifth layer 600, and Figure 3I schematically shows the production of the fifth layer 600 onto the previously prepared bonded first to fourth layers 540 to create a shoe upper or upper Bonded first through fifth layers 640 of blank 1000 . Specifically, FIG. 3F shows that a fifth filamentous structure (such as any having the characteristics and properties of the filamentary structure described above) is formed, for example, through a solid deposition modeling process and is formed into a plurality of path segments by extruding the fifth material. (e.g., having any of the path and/or path segment characteristics described above). Optionally, this fifth layer 600 can be extruded into a fifth continuous path. In this illustrative example, a fifth path (optionally a continuous path) of fifth filamentous structures forms the following portions of fifth layer 600: (a) fifth lateral rear heel portion 602 (eg, and/or or on the lateral side 602s of the ankle/foot opening 614 of the fifth layer 600), (b) the fifth lateral midfoot 604 (such as with and/or on the lateral side 604s of the instep opening 612 of the fifth layer 600 (or (next to the inner edge), (c) fifth forefoot 506 (as it bridges from the lateral to medial side of fifth layer 600, in front of the midfoot), (d) fifth medial midfoot 608 (as with and/ or on the inner side 608s (or inner edge) of the instep opening 612 of the fifth layer 600), and (e) the fifth inner rear heel portion 610 (such as on and/or on the ankle/foot of the fifth layer 600 Inner side of opening 614 (next to 610s). The vertical dashed lines shown in Figure 3F generally define and divide the fifth layer 600 into three parts: (a) the posterior third (including the lateral rear heel portion 602 and the medial rear heel portion 610), (b) the middle third one third (including the lateral midfoot 604 and the medial midfoot 608), and (c) the anterior third (including the forefoot 606). In at least some examples of the present invention, the fifth layer 600 is composed primarily of or even the filamentous structural structure (optionally formed as a continuous path and/or a monolithic structure). The white space visible in Figure 3H for this exemplary fifth layer 600 constitutes the open space between the path segments of the filamentary structure (eg, where the fifth layer 600 is fully visible).

While the path segments of fifth layer 600 may be extruded in any desired order without departing from the invention, in some examples of the invention, the perimeter (e.g., 600P) may be extruded first, and the remainder of fifth layer 600 may be extruded next. Partially, for example, in a "raster"-like manner, to fill the area within the surrounding 600P. In the illustrated example, the extruded overall path of the fifth layer 600 lays out the fifth filamentary structure as a fifth plurality of non-intersecting spaced path segments over a majority of the overall surface area of the fifth layer 600 , with the fifth layer The 600 essentially extends in the front-to-back direction. As shown in Figure 3H, in the lateral rear heel portion 602, the lateral midfoot portion 604, the forefoot portion 606, and the medial rear heel portion 610, a fifth plurality of non-intersecting path segments are gently curved from the rear foot portion. The heel portion 602/610 extends forward. However, in the medial midfoot 608, at least some of the fifth plurality of non-intersecting path segments extend in a serpentine configuration including at least two peaks (608P) and at least two valleys (608V). The path segments in these various regions 602, 604, 606, 608, 610 may have any of the features and/or options previously described for the path segments shown in Figures 2A-2F.

As further shown in Figure 3H, the fifth path of the filamentous structure is defined at a first inner edge of the lateral instep opening edge 604s, at a first outer edge 604t of the lateral midfoot region 604, and at a second inner edge of the medial instep opening edge 608s. edge, and a second outer edge 608t in the medial midfoot region 608. An instep opening 612 of the fifth layer 600 is defined between a first inner edge at 604s and a second inner edge at 608s. The fifth path of the filamentary structure in this exemplary fifth layer 600 includes: (a) a first plurality of non-intersecting spaced path segments located between the first inner edge 604s and the first outer edge 604t, wherein The first plurality of non-intersecting spaced path segments of the five paths are linear and/or curved without defining peaks and valleys and/or (b) a second plurality of non-intersecting spaced path segments located between the second inner edge 608s and the second outer edge 608t A plurality of non-intersecting spaced path segments, with a second plurality of non-intersecting spaced path segments located in the fifth path between the second inner edge at 608s and the second outer edge 608t extending in a serpentine configuration And have at least two peaks 608P and at least two valleys 608V. The fifth layer 600 of Figure 3H may include at least 4 path segments, at least 6 path segments, at least 8 path segments, at least 10 path segments, or even at least 4 path segments extending substantially parallel and/or having the serpentine configuration. 12 path segments.

As is apparent from a comparison of Figures 3D, 3F, and 3H, the path segments of the third layer 400, the fourth layer 500, and the fifth layer 600 extend in a generally parallel manner over a large portion of their overall paths. Accordingly, the path segments of the fifth layer 600 may be squeezed generally parallel to the path segments of the third layer 400 and/or the fourth layer 500 over a majority of their overall path length, as shown in Figures 2C and 2E. out and/or overlapping. If desired: (a) at least 25% (and in some examples, at least 40%, at least 50%, at least 60%, at least 75%, at least 85%, or even at least 90%) of the overall path length of the fifth layer 600 %) will overlap with path segments of at least one of the third layer 400 and/or the fourth layer 500 in the manner shown in Figures 2C and 2E and/or (b) the third layer 400 and/or the fourth layer At least 25% (and in some examples, at least 40%, at least 50%, at least 60%, at least 75%, at least 85%, or even at least 90%) of the overall path length of 500 will be as shown in Figures 2C and 2E The manner shown overlaps with the path segments of the fifth layer 600. In at least some examples of the invention: (b) the fifth path of the fifth layer 600 is less than 50% (and in some examples, less than 40%, less than 30%, less (b) the fifth path of the fifth layer 600 is less than 50% of the overall length of the fifth path (and in some cases In the example, less than 40%, less than 30%, less than 20%, or even less than 10%) overlaps with the second path of the second layer 350, (c) the fifth path of the fifth layer 600 is on the A path that overlaps less than 50% (and in some examples, less than 40%, less than 30%, less than 20%, or even less than 10%) of the entire length of the first path of the first layer 300 , and/or (d) the fifth path of the fifth layer 600 is less than 50% (and in some examples, less than 40%, less than 30%, less than 20%, or less than 50% of the overall length of the second path) Even less than 10%) overlaps with the second path of the second layer 350.

Therefore, when the fifth layer 600 is extruded, the filamentous structures of the fifth layer 600 will directly contact the filamentary structures of the third layer 400 and/or the fourth layer 500 (at the overlapping contact area 202). Heat from the fifth layer 600 (and/or another heat source) as it is extruded causes path segments of the fifth filamentary structure and path segments of the third filamentary structure and/or the path of the fourth filamentary structure. The contact areas 202 where the path segments of the fifth filamentary structure contact one or both of the path segments of the third filamentary structure and/or the path segments of the fourth filamentary structure are fused together (such as the contact areas 202 of the fifth layer 600 The filamentary structural material may be polymerized and seamlessly connected to the filamentary construction material of the third layer 400 and/or the fourth layer 500). In this manner, the third layer 400 and/or the fourth layer 500 of the shoe upper or shoe upper blank material 1000 can be fixedly connected to the fifth layer of the shoe upper or shoe upper blank material 1000 at the contact area 202 in an adhesive-free manner. 600.

As is apparent from a comparison of Figure 3H with Figures 3A and 3B, the path segments of the fifth layer 600 will substantially intersect the path segments of the first layer 300 and the second layer 350 over a substantial portion of their overall paths. The intersecting path segments form a grid or generally matrix pattern, as can be seen in the combined first through fifth layers 640 shown in Figure 3I. The path segments of the fifth layer 600 may intersect the path segments of the first layer 300 and/or the second layer 350 at any desired angle, such as from 5° to 175°, and in some examples, from 15° to 165°. , from 25° to 155°, from 35° to 145°, from 45° to 135°, from 55° to 125°, from 60° to 120°, from 65° to 95° and so on. Therefore, when the fifth layer 600 is extruded, the filamentous structures of the fifth layer 600 will directly contact the filamentary structures of the first layer 300 and the filamentary structures of the second layer (at the intersecting contact area 202). Heat from the fifth layer 600 (and/or another heat source) as it is extruded causes the path segments of the fifth filamentary structure to coincide with the path segments of the first filamentary structure and/or the path of the second filamentary structure. The contact areas 202 where the path segments of the fifth filamentary structure contact one or both of the path segments of the first filamentary structure and/or the path segments of the second filamentary structure are fused together (e.g., of the fifth layer 600 The filamentary structural material may be polymerized and seamlessly connected to the filamentary construction material of the first layer 300 and/or the second layer 350).

In these ways, the fifth layer 600 of the shoe upper or shoe upper blank material 1000 can be fixedly connected to the first layer 300, the second layer 350, the second layer 350, of the shoe upper or shoe upper blank material 1000 at the contact area 202 in an adhesive-free manner. The third layer 400 and the fourth layer 500 form the combined first to fifth layers 640. The upper components or mid-materials including the combined first to fifth layers 640 form a single structure, in which the first layer 300, the second layer 350, the third layer 400, the fourth layer 500, and the fifth layer 600 are Non-adhesive fusion holds together. The upper component or mid-material including the combined first to fifth layers 640 may be primarily or even composed of the first layer 300, the second layer 350, the third layer 400, the fourth layer 500, and the fifth layer 600. composition.

In the fifth layer 600, path segments in one area need not be at constant spacing from directly adjacent path segments in other areas of the fifth layer 600. For example, as shown in Figure 3H, the plurality of non-intersecting spaced path segments in the front foot 606 of the fifth layer 600 are more closely spaced than the plurality of non-intersecting spaced path segments in the mid-foot 604/608, and/or The plurality of non-intersecting spaced path segments in the forefoot 606 and/or midfoot 604/608 of the fifth layer 600 are more closely spaced than the plurality of non-intersecting spaced path segments in the heel 602/610 of the fifth layer 600. interval.

After the fifth layer 600 is extruded (eg, onto the first layer 300 , the second layer 350 , the third layer 400 , the fourth layer 500 , and/or the substrate 106 ), the entire upper or upper blank may then be applied. The sixth layer 700 of 1000 to the combined first to fifth layers 640. Figure 3J shows individual path segments of this exemplary sixth layer 700, and Figure 3K schematically shows the production of the sixth layer 700 onto the previously prepared bonded first through fifth layers 640 to create a shoe upper or upper Bonded first through sixth layers 740 of blank 1000 . Specifically, FIG. 3J shows that a sixth filamentous structure (such as any having the characteristics and characteristics of the above-described filamentary structure) is formed, for example, through a solid deposition modeling process and is formed into a plurality of path segments by extruding the sixth material. The sixth layer 700 is formed by having any of the path and/or path segment characteristics described above. Optionally, this sixth layer 700 can be extruded into a sixth continuous path. In this illustrative example, the sixth path (optionally a continuous path) of the sixth filamentous structure forms the following portions of the sixth layer 700: (a) the sixth lateral rear heel portion 702 (eg, and/or or next to the lateral 702s of the ankle/foot opening 714 of the sixth layer 700), (b) the sixth lateral midfoot 704 (such as with and/or lateral 704s of the instep opening 712 of the sixth layer 700 (or (next to the inner edge), (c) sixth forefoot 706 (as it bridges from the lateral to medial side of sixth layer 700, in front of the midfoot), (d) sixth medial midfoot 708 (as with and/or or next to the medial 708s (or inner edge) of the instep opening 712 of the sixth layer 700), and (e) the sixth medial rear heel portion 710 (such as on and/or on the ankle/foot of the sixth layer 700 Inner side of opening 714 (next to 710s). The vertical dashed lines shown in Figure 3F generally define and divide the sixth layer 700 into three parts: (a) the posterior third (including the lateral rear heel portion 702 and the medial rear heel portion 710), (b) the middle third one third (including the lateral midfoot 704 and the medial midfoot 708), and (c) the anterior third (including the forefoot 706). In at least some examples of the present invention, the sixth layer 700 is composed primarily of or even the filamentous structural structure (optionally formed as a continuous path and/or a monolithic structure). The white space visible in Figure 3J for this exemplary sixth layer 700 constitutes the open space between the path segments of the filamentous structure (eg, where the sixth layer 700 is fully visible).

Although the path segments of the sixth layer 700 may be extruded in any desired order without departing from the invention, in some examples of the invention, the perimeter (eg, 700P) may be extruded first, and the remainder of the sixth layer 700 may be extruded next. Partially, for example, in a "raster"-like manner, to fill the area within the surrounding 700P. In the illustrated example, the extruded overall path of the sixth layer 700 lays out the sixth filamentary structure as a sixth plurality of non-intersecting spaced path segments over a majority of the overall surface area of the sixth layer 700, with the sixth layer The 700 essentially extends in the front-to-back direction. As shown in Figure 3J, in the lateral rear heel portion 702, the forefoot portion 706, the medial midfoot portion 708, and the medial rear heel portion 710, a sixth plurality of non-intersecting path segments are gently curved from the rear foot portion. The heel 702/710 extends forward. However, in the lateral midfoot 704, at least some of the sixth plurality of non-intersecting path segments extend in a serpentine configuration including at least two peaks (708P) and at least two valleys (708V). The path segments in these various regions 702, 704, 706, 708, 710 may have any of the features and/or options previously described for the path segments shown in Figures 2A-2F.

As further shown in Figure 3J, the sixth path of the filamentous structure is defined at a first inner edge of the lateral instep opening edge 704s, at a first outer edge 704t of the lateral midfoot region 704, and at a second inner edge of the medial instep opening edge 708s. edge, and a second outer edge 708t at the medial midfoot region 708. An instep opening 712 of the sixth layer 700 is defined between a first inner edge at 704s and a second inner edge at 708s. The sixth path of the filamentary structure in this exemplary layer 700 includes: (a) a first plurality of non-intersecting spaced path segments located between the first inner edge at 704s and the first outer edge 704t, wherein the first plurality of non-intersecting spaced path segments are located at 704s a first plurality of non-intersecting spaced path segments of the sixth path between the first inner edge and the first outer edge 704t extending in a serpentine configuration and having at least two peaks 708P and at least two valleys 708V, and (b) A second plurality of non-intersecting spaced path segments located between the second inner edge 708s and the second outer edge 708t, wherein the second plurality of non-intersecting spaced path segments of the sixth path are linear and/or curved There is no definition of plural peaks and troughs. The sixth layer 700 of Figure 3J may include at least 4 path segments, at least 6 path segments, at least 8 path segments, at least 10 path segments, or even at least 4 path segments extending substantially parallel and/or having the serpentine configuration. 12 path segments.

In the sixth layer 700, path segments in one area need not be at constant spacing from directly adjacent path segments in other areas of the sixth layer 700. For example, as shown in Figure 3J, the plurality of non-intersecting spaced path segments in the front foot 706 of the sixth layer 700 are more closely spaced than the plurality of non-intersecting spaced path segments in the midfoot 704/708, and/or The plurality of non-intersecting spaced path segments in the forefoot 706 and/or midfoot 704/708 of the sixth layer 700 are more closely spaced than the plurality of non-intersecting spaced path segments in the heel 702/710 of the sixth layer 700 interval.

It can be clearly seen from the comparison between Figure 3J and Figures 3A, 3B, 3D, 3F, and 3H that the path segment of the sixth layer 700 will be the same as the first layer 300, the second layer 350, the third layer 400, and the fourth layer 500. , and the path segments of the fifth layer 600 substantially intersect over a large portion of their overall paths. The intersecting path segments form a generally diamond shape, as can be seen from the bonded first through sixth layers 740 shown in Figure 3K. The path segments of the sixth layer 700 may intersect the path segments of the first layer 300 , the second layer 350 , the third layer 400 , the fourth layer 500 , and/or the fifth layer 600 at any desired angle, such as from 5° to 175°, and in some examples, from 15° to 165°, from 25° to 155°, from 35° to 145°, from 45° to 135°, from 55° to 125°, from 60° to 120° °, from 65° to 95°, etc. In at least some examples of the invention: (b) the sixth path of the sixth layer 700 is less than 50% (and in some examples, less than 40%, less than 30%, less 20%, or even less than 10%) with the first path of the first layer 300, the second path of the second layer 350, the third path of the third layer 400, the fourth path of the fourth layer 500, and /or one or more of the fifth paths of the fifth layer 600 overlap, and/or (b) the sixth paths of the sixth layer 700 are respectively in the first path, the second path, the third path, the fourth path, and /or less than 50% (and in some examples, less than 40%, less than 30%, less than 20%, or even less than 10%) of the overall length of the fifth path is identical to the first layer 300 One or more of a path, the second path of the second layer 350, the third path of the third layer 400, the fourth path of the fourth layer 500, and/or the fifth path of the fifth layer 600 overlap.

Therefore, when the sixth layer 700 is extruded, the filamentous structure of the sixth layer 700 will directly contact the filamentary structure of the first layer 300, the filamentary structure of the second layer 350, the filamentary structure of the third layer 400, The filamentary structure of the fourth layer 500, and/or the filamentary structure of the fifth layer 600 (at the intersecting contact area 202). The heat from the sixth layer 700 (and/or another heat source) as it is extruded causes the path segments of the sixth filamentary structure to differ from the path segments of the first filamentary structure, the path segments of the second filamentary structure, Any one or any combination of the path segment of the third filamentary structure, the path segment of the fourth filamentary structure, and/or the path segment of the fifth filamentary structure contacts the first filament at the path segment of the sixth filamentary structure. Any one of the path segment of the second filamentous structure, the path segment of the third filamentary structure, the path segment of the fourth filamentary structure, and/or the path segment of the fifth filamentary structure, or any of the path segments of the fifth filamentous structure. Any combination of contact areas 202 may be fused together (e.g., the filamentous construction materials of sixth layer 700 may be fused with those of first layer 300 , second layer 350 , third layer 400 , fourth layer 500 , and/or fifth layer 600 Filamentous construction materials aggregate and connect seamlessly). In this way, the sixth layer 700 of the shoe upper or shoe upper blank material 1000 can be fixedly connected to the first layer 300 , the second layer 350 , 350 of the shoe upper or shoe upper blank material 1000 at the contact area 202 in an adhesive-free manner. The third layer 400, the fourth layer 500, and/or the fifth layer 600 form the combined first to sixth layers 740. The upper components or midsole including the combined first to sixth layers 740 form a single structure, wherein the first layer 300, the second layer 350, the third layer 400, the fourth layer 500, the fifth layer 600, and The sixth layer 700 is held together by non-adhesive fusion. The upper component or mid-material including the combined first to sixth layers 740 may be mainly composed of or even composed of the first layer 300, the second layer 350, the third layer 400, the fourth layer 500, the fifth layer 600, and The sixth floor consists of 700.

After the sixth layer 700 is extruded (eg, onto the first layer 300 , the second layer 350 , the third layer 400 , the fourth layer 500 , the fifth layer 600 , and/or the substrate 106 ), the overall upper may then be applied. Or the seventh layer 800 of the upper blank material 1000 to the combined first to sixth layers 740. Figure 3L shows individual path segments of this exemplary seventh layer 800, and Figure 3M schematically shows the production of the seventh layer 800 onto the previously prepared bonded first through sixth layers 740 to create a shoe upper or upper Bonded first through seventh layers 840 of blank 1000 . Specifically, FIG. 3L shows that a seventh filamentous structure (such as any having the characteristics and characteristics of the above-described filamentary structure) is formed, for example, through a solid deposition modeling process and is formed into a plurality of path segments by extruding the seventh material. (e.g., having any of the path and/or path segment characteristics described above). Optionally, this seventh layer 800 can be extruded into a seventh continuous path. In this illustrative example, the seventh path (optionally a continuous path) of the seventh filamentous structure forms the following portions of seventh layer 800: (a) seventh lateral rear heel portion 802 (eg, and/or or next to the lateral side 802s of the ankle/foot opening 814 of the seventh layer 800), (b) the seventh lateral midfoot 804 (such as with and/or next to the lateral 804s of the instep opening 812 of the seventh layer 800 (or (next to the inner edge)), (c) seventh forefoot 706 (as it bridges from the lateral to medial side of seventh layer 800, in front of the midfoot), (d) seventh medial midfoot 808 (as with and/ or on the inner side 808s (or inner edge) of the instep opening 812 of the seventh layer 800), and (e) the seventh inner rear heel portion 810 (such as on and/or on the ankle/foot of the seventh layer 800 Inner side of opening 814 (next to 810s). The vertical dashed lines shown in Figure 3L generally define and divide the seventh layer 800 into three parts: (a) the posterior third (including the lateral rear heel portion 802 and the medial rear heel portion 810), (b) the middle third one third (including the lateral midfoot 804 and the medial midfoot 808), and (c) the anterior third (including the forefoot 806). In at least some examples of the present invention, the seventh layer 800 is composed primarily of or even the filamentary structure (optionally formed as a continuous path and/or a monolithic structure). The white space visible in Figure 3L for this exemplary seventh layer 800 constitutes the open space between the path segments of the filamentary structure (eg, where the seventh layer 800 is fully visible).

Although the path segments of the seventh layer 800 can be extruded in any desired order without departing from the invention, in some examples of the invention, the perimeter (e.g., 800P) can be extruded first, and the remainder of the seventh layer 800 can be extruded subsequently. Partially, for example, in a "raster"-like manner, to fill the area within the surrounding 800P. In the illustrated example, the extruded overall path of the seventh layer 800 lays out the seventh filamentary structure as a seventh plurality of non-intersecting spaced path segments over a majority of the overall surface area of the seventh layer 800, with the seventh layer The 800 essentially extends in the front-to-back direction. As shown in Figure 3L, in the lateral rear heel portion 802, the forefoot portion 806, the medial midfoot portion 808, and the medial rear heel portion 810, a seventh plurality of non-intersecting path segments are gently curved from the rear foot portion. The heel portion 702/710 extends forward. However, in the lateral midfoot 804, at least some of the seventh plurality of non-intersecting path segments extend in a serpentine configuration including at least two peaks (808P) and at least two valleys (808V). The path segments in these various regions 802, 804, 806, 808, 810 may have any of the features and/or options previously described for the path segments shown in Figures 2A-2F.

As further shown in Figure 3L, the seventh path of the filamentous structure is defined at a first inner edge of the lateral instep opening edge 804s, at a first outer edge 804t of the lateral midfoot region 804, and at a second inner edge of the medial instep opening edge 808s. edge, and a second outer edge 808t at the medial midfoot region 808. An instep opening 812 of the seventh layer 800 is defined between a first inner edge at 804s and a second inner edge at 808s. The seventh path of the filamentary structure in this exemplary layer 800 includes: (a) a first plurality of non-intersecting spaced path segments located between the first inner edge at 804s and the first outer edge 804t, wherein the a first plurality of non-intersecting spaced path segments of the seventh path between the first inner edge and the first outer edge 804t extending in a serpentine configuration and having at least two peaks 808P and at least two valleys 808V, and (b) A second plurality of non-intersecting spaced path segments located between the second inner edge 808s and the second outer edge 808t, wherein the second plurality of non-intersecting spaced path segments of the seventh path are linear and/or curved There is no definition of plural peaks and troughs. The seventh layer 800 of Figure 3L may include at least 4 path segments, at least 6 path segments, at least 8 path segments, at least 10 path segments, or even at least 4 path segments extending substantially parallel and/or having the serpentine configuration. 12 path segments.

As is apparent from a comparison of Figures 3J and 3L, the path segments of the sixth layer 700 and the seventh layer 800 extend in a generally parallel manner over a large portion of their overall paths. Accordingly, the path segments of the seventh layer 800 may be extruded generally parallel to and/or overlap the path segments of the sixth layer 700 over a majority of their overall path lengths as shown in Figures 2C and 2E. If desired: (a) at least 25% (and in some examples, at least 40%, at least 50%, at least 60%, at least 75%, at least 85%, or even at least 90%) of the overall path length of the seventh layer 800 %) will overlap with the path segments of the sixth layer 700 in a manner as shown in Figures 2C and 2E and/or (b) at least 25% (and in some examples, at least 40%) of the overall path length of the sixth layer 700 %, at least 50%, at least 60%, at least 75%, at least 85%, or even at least 90%) will overlap the path segments of the seventh layer 800 in a manner as shown in Figures 2C and 2E.

It can also be clearly seen from the comparison between Figure 3L and Figures 3A, 3B, 3D, 3F, and 3H that the path segment of the seventh layer 800 will be the same as the first layer 300, the second layer 350, the third layer 400, and the fourth layer. 500, and the path segments of the fifth layer 600 substantially intersect over a large portion of their overall paths. The intersecting path segments form a generally diamond shape, as can be seen from the bonded first through seventh layers 840 shown in Figure 3M. The path segments of the seventh layer 800 may intersect the path segments of the first layer 300 , the second layer 350 , the third layer 400 , the fourth layer 500 , and/or the fifth layer 600 at any desired angle, such as from 5° to 175°, and in some examples, from 15° to 165°, from 25° to 155°, from 35° to 145°, from 45° to 135°, from 55° to 125°, from 60° to 120° °, from 65° to 95°, etc. In at least some examples of the invention: (b) the seventh path of seventh layer 800 is less than 50% (and in some examples, less than 40%, less than 30%, less 20%, or even less than 10%) with the first path of the first layer 300, the second path of the second layer 350, the third path of the third layer 400, the fourth path of the fourth layer 500, and /or one or more of the fifth paths of the fifth layer 600 overlap, and/or (b) the seventh paths of the seventh layer 800 are respectively in the first path, the second path, the third path, the fourth path, and /or less than 50% (and in some examples, less than 40%, less than 30%, less than 20%, or even less than 10%) of the overall length of the fifth path is consistent with the first layer 300 One or more of a path, the second path of the second layer 350, the third path of the third layer 400, the fourth path of the fourth layer 500, and/or the fifth path of the fifth layer 600 overlap.

Therefore, when the seventh layer 800 is extruded, the filamentous structure of the seventh layer 800 will directly contact the first layer 300, the second layer 350, the third layer 400, the fourth layer 500, and/or the fifth layer 600. one or more filamentous structures (at intersecting contact areas 202). The heat from the seventh layer 800 (and/or another heat source) as it is extruded causes the path segments of the seventh filamentary structure to differ from the path segments of the first filamentary structure, the path segments of the second filamentary structure, Any one or any combination of the path segment of the third filamentary structure, the path segment of the fourth filamentary structure, and/or the path segment of the fifth filamentary structure contacts the first filament at the path segment of the seventh filamentous structure. Any one of the path segment of the second filamentous structure, the path segment of the third filamentary structure, the path segment of the fourth filamentary structure, and/or the path segment of the fifth filamentary structure, or any of the path segments of the fifth filamentous structure. Any combination of contact areas 202 may be fused together (e.g., the filamentous construction materials of seventh layer 800 may be fused with those of first layer 300 , second layer 350 , third layer 400 , fourth layer 500 , and/or fifth layer 600 Filamentous construction materials aggregate and connect seamlessly).

In these ways, the seventh layer 800 of the shoe upper or shoe upper blank material 1000 can be fixedly connected to the first layer 300, the second layer 350, the second layer 350, of the shoe upper or shoe upper blank material 1000 at the contact area 202 in an adhesive-free manner. The third layer 400, the fourth layer 500, the fifth layer 600, and/or the sixth layer 700 form the combined first to seventh layers 840. The upper components or mid-materials including the combined first to seventh layers 840 form a single structure, wherein the first layer 300, the second layer 350, the third layer 400, the fourth layer 500, the fifth layer 600, the The sixth layer 700 and the seventh layer 800 are fixed together by non-adhesive fusion. The upper component or mid-material including the combined first to seventh layers 840 may be mainly composed of or even composed of the first layer 300, the second layer 350, the third layer 400, the fourth layer 500, the fifth layer 600, the It consists of the sixth floor 700 and the seventh floor 800.

In the seventh layer 800, path segments in one area need not be at constant spacing from directly adjacent path segments in other areas of the seventh layer 800. For example, as shown in Figure 3L, the plurality of non-intersecting spaced path segments in the front foot 806 of the seventh layer 800 are more closely spaced than the plurality of non-intersecting spaced path segments in the midfoot 804/808, and/or The plurality of non-intersecting spaced path segments in the forefoot 806 and/or midfoot 804/808 of the seventh layer 800 are more closely spaced than the plurality of non-intersecting spaced path segments in the heel 802/810 of the seventh layer 800 interval.

After extruding the seventh layer 800 (eg, onto the first layer 300, the second layer 350, the third layer 400, the fourth layer 500, the fifth layer 600, the sixth layer 700, and/or the substrate 106), the An eighth layer 900 of the overall upper or upper blank 1000 is then applied to the bonded first through sixth layers 740. Figure 3N shows individual path segments of this exemplary eighth layer 900, and Figure 3O schematically shows the production of the eighth layer 900 onto the previously prepared bonded first through sixth layers 740 to create a shoe upper or upper Bonded first through seventh layers 840 of blank 1000 . Specifically, FIG. 3N shows, for example, through a solid deposition modeling process, an eighth filamentous structure (such as any one having the characteristics and characteristics of the above-described filamentary structure) is formed and formed into a plurality of path segments by extruding the eighth material. (e.g., having any of the path and/or path segment characteristics described above). Optionally, this eighth layer 900 can be extruded into an eighth continuous path. In this illustrative example, the eighth path (optionally a continuous path) of the eighth filamentous structure forms the following portions of the eighth layer 900: (a) the eighth lateral rear heel portion 902 (eg, and/or or next to the lateral side 902s of the ankle/foot opening 914 of the eighth layer 900), (b) the eighth lateral midfoot 904 (such as with and/or next to the lateral 904s of the instep opening 912 of the eighth layer 900 (or (next to the inner edge)), (c) eighth forefoot 706 (as it bridges from the lateral to medial side of eighth layer 900, in front of the midfoot), (d) eighth medial midfoot 908 (as with and/ or on the inner side 908s (or inner edge) of the instep opening 912 of the eighth layer 900), and (e) the eighth inner rear heel portion 910 (such as on and/or on the ankle/foot of the eighth layer 900 Inside opening 914 (next to 910s). The vertical dashed lines shown in Figure 3N generally define and divide the eighth layer 900 into three parts: (a) the posterior third (including the lateral rear heel portion 902 and the medial rear heel portion 910), (b) the middle third one third (including the lateral midfoot 904 and the medial midfoot 908), and (c) the anterior third (including the forefoot 906). In at least some examples of the present invention, the eighth layer 900 is composed primarily of or even the filamentary structure (optionally formed as a continuous path and/or a monolithic structure). The white space visible in Figure 3N for this exemplary eighth layer 900 constitutes the open space between the path segments of the filamentous structure (eg, where the eighth layer 900 is fully visible).

While the path segments of the eighth layer 900 may be extruded in any desired order without departing from the invention, in some examples of the invention the perimeter (e.g. 900P) may be extruded first and the remainder of the eighth layer 900 may be extruded subsequently. Partially, for example, in a "raster"-like manner, to fill the area within the surrounding 900P. In the illustrated example, the extruded overall path of the eighth layer 900 lays out the eighth filamentary structure as an eighth plurality of non-intersecting spaced path segments over a majority of the overall surface area of the eighth layer 900 , with the eighth layer The 900 essentially extends front-to-back. As shown in Figure 3N, in the lateral rear heel portion 902, the forefoot portion 906, the medial midfoot portion 908, and the medial rear heel portion 910, an eighth plurality of non-intersecting path segments are gently curved from the rear foot portion. The heel 902/910 extends forward. However, in the lateral midfoot 904, at least some of the eighth plurality of non-intersecting path segments extend in a serpentine configuration including at least two peaks (908P) and at least two valleys (908V). The path segments in these various regions 902, 904, 906, 908, 910 may have any of the features and/or options previously described for the path segments shown in Figures 2A-2F.

As further shown in Figure 3N, the eighth path of the filamentous structure is defined at a first inner edge of the lateral instep opening edge 904s, at a first outer edge 904t of the lateral midfoot region 904, and at a second inner edge of the medial instep opening edge 908s. edge, and a second outer edge 808t at the medial midfoot region 908. An instep opening 912 of the eighth layer 900 is defined between a first inner edge at 904s and a second inner edge at 908s. The eighth path of the filamentary structure in this exemplary layer 900 includes: (a) a first plurality of non-intersecting spaced path segments located between the first inner edge at 904s and the first outer edge 904t, wherein the a first plurality of non-intersecting spaced path segments of the eighth path between the first inner edge and the first outer edge 904t extend in a serpentine configuration and have at least two peaks 908P and at least two valleys 908V, and (b) A second plurality of non-intersecting spaced path segments located between the second inner edge 908s and the second outer edge 908t, wherein the second plurality of non-intersecting spaced path segments of the eighth continuous path are linear and/or Curved without defined plural peaks and troughs. The eighth layer 900 of FIG. 3N may include at least 4 path segments, at least 6 path segments, at least 8 path segments, at least 10 path segments, or even at least 4 path segments extending substantially parallel and/or having the serpentine configuration. 12 path segments.

As is apparent from a comparison of Figures 3J, 3L, and 3N, the path segments of the sixth layer 700, the seventh layer 800, and the eighth layer 900 extend in a generally parallel manner over a large portion of their overall paths. Accordingly, the path segments of the eighth layer 900 may be squeezed generally parallel to the path segments of the sixth layer 700 and/or the seventh layer 800 over a majority of their overall path length in a manner as shown in Figures 2C and 2E. out and/or overlapping. If desired: (a) at least 25% (and in some examples, at least 40%, at least 50%, at least 60%, at least 75%, at least 85%, or even at least 90%) of the overall path length of the eighth layer 900 %) will overlap with the path segments of at least one of the sixth layer 700 and/or the seventh layer 800 in the manner shown in Figures 2C and 2E and/or (b) the sixth layer 700 and/or the seventh layer At least 25% (and in some examples, at least 40%, at least 50%, at least 60%, at least 75%, at least 85%, or even at least 90%) of the overall path length of 800 will be as shown in Figures 2C and 2E The manner shown overlaps with the path segments of the eighth layer 900. Therefore, when the eighth layer 900 is extruded, the filamentous structures of the eighth layer 900 will directly contact the filamentary structures of the sixth layer 700 and/or the seventh layer 800 (at the overlapping contact area 202). Heat from the eighth layer 900 (and/or another heat source) as it is extruded causes path segments of the eighth filamentary structure and path segments of the sixth filamentary structure and/or paths of the seventh filamentary structure. The contact areas 202 where the path segments of the eighth filamentary structure contact one or both of the path segments of the sixth filamentary structure and/or the path segments of the seventh filamentary structure are fused together (such as the contact areas 202 of the eighth layer 900 The filamentary structural material may be polymerized and seamlessly connected to the filamentary construction material of the sixth layer 700 and/or the seventh layer 800). In this manner, the sixth layer 700 and/or the seventh layer 800 of the shoe upper or shoe upper blank material 1000 can be fixedly connected to the eighth layer of the shoe upper or shoe upper blank material 1000 at the contact area 202 in an adhesive-free manner. 900.

It can also be clearly seen from the comparison between Figure 3N and Figures 3A, 3B, 3D, 3F, and 3H that the path segment of the eighth layer 900 will be the same as the first layer 300, the second layer 350, the third layer 400, and the fourth layer. 500, and the path segments of the fifth layer 600 substantially intersect over a large portion of their overall paths. The intersecting path segments form a generally diamond shape, as can be seen from the combined first through eighth layers (ie, upper blank 1000) shown in Figures 3O and 3P. The path segments of the eighth layer 900 may intersect the path segments of the first layer 300 , the second layer 350 , the third layer 400 , the fourth layer 500 , and/or the fifth layer 600 at any desired angle, such as from 5° to 175°, and in some examples, from 15° to 165°, from 25° to 155°, from 35° to 145°, from 45° to 135°, from 55° to 125°, from 60° to 120° °, from 65° to 95°, etc. In at least some examples of the invention: (b) the eighth path of the eighth layer 900 is less than 50% (and in some examples, less than 40%, less than 30%, less 20%, or even less than 10%) with the first path of the first layer 300, the second path of the second layer 350, the third path of the third layer 400, the fourth path of the fourth layer 500, and /or one or more of the fifth paths of the fifth layer 600 overlap, and/or (b) the eighth paths of the eighth layer 900 are respectively in the first path, the second path, the third path, the fourth path, and /or less than 50% (and in some examples, less than 40%, less than 30%, less than 20%, or even less than 10%) of the overall length of the fifth path is consistent with the first layer 300 One or more of a path, the second path of the second layer 350, the third path of the third layer 400, the fourth path of the fourth layer 500, and/or the fifth path of the fifth layer 600 overlap.

Therefore, when the eighth layer 900 is extruded, the filamentous structure of the eighth layer 900 will directly contact the first layer 300, the second layer 350, the third layer 400, the fourth layer 500, and/or the fifth layer 600. one or more filamentous structures (at intersecting contact areas 202). The heat from the eighth layer 900 (and/or another heat source) as it is extruded causes the path segments of the eighth filamentary structure to differ from the path segments of the first filamentary structure, the path segments of the second filamentary structure, Any one or any combination of the path segment of the third filamentary structure, the path segment of the fourth filamentary structure, and/or the path segment of the fifth filamentary structure contacts the first filament at the path segment of the seventh filamentary structure. Any one of the path segment of the second filamentous structure, the path segment of the third filamentary structure, the path segment of the fourth filamentary structure, and/or the path segment of the fifth filamentary structure, or any of the path segments of the fifth filamentous structure. Any combination of contact areas 202 may be fused together (e.g., the filamentous construction material of the eighth layer 900 may be fused with the filamentous structural materials of the first layer 300 , the second layer 350 , the third layer 400 , the fourth layer 500 , and/or the fifth layer 600 Filamentous construction materials aggregate and connect seamlessly).

In these ways, the eighth layer 900 of the shoe upper or shoe upper blank material 1000 can be fixedly connected to the first layer 300, the second layer 350, the second layer 350, the shoe upper or shoe upper blank material 1000 at the contact area 202 in an adhesive-free manner. The third layer 400, the fourth layer 500, the fifth layer 600, the sixth layer 700, and/or the seventh layer 800 form the combined first to eighth layers (that is, the shoe upper blank material 1000). The shoe upper component or middle material including the combined first to eighth layers (shoe upper blank material 1000) forms a single structure, in which the first layer 300, the second layer 350, the third layer 400, the fourth layer 500, The fifth layer 600, the sixth layer 700, the seventh layer 800, and the eighth layer 900 are fixed together by non-adhesive fusion. The upper component or mid-material including the combined first to seventh layers 840 may be mainly composed of or even composed of the first layer 300, the second layer 350, the third layer 400, the fourth layer 500, the fifth layer 600, the It consists of the sixth floor 700, the seventh floor 800, and the eighth floor 900.

In the eighth layer 900, path segments in one region need not be at constant spacing from directly adjacent path segments in other regions of the eighth layer 900. For example, as shown in Figure 3N, the plurality of non-intersecting spaced path segments in the front foot 906 of the eighth layer 900 are more closely spaced than the plurality of non-intersecting spaced path segments in the mid-foot 904/908, and/or The plurality of non-intersecting spaced path segments in the forefoot 906 and/or midfoot 904/908 of the eighth layer 900 are more closely spaced than the plurality of non-intersecting spaced path segments in the heel 902/910 of the eighth layer 900 interval.

After all desired layers of the upper or upper blank 1000 are formed, the extruded and fused layers form the fused upper component (eg, upper blank 1000). Next, the fused upper component may be removed from the base substrate 106, upon which the component may be extruded, optionally trimmed (e.g., around its peripheral edge, if desired), or otherwise treated (e.g., coated, painted etc.), optionally joined to another upper component, and/or incorporated into the footwear structure, as will be explained in more detail below. As noted above, the surface 106s of the substrate 106 upon which the filamentary construction layer is extruded may be smooth or otherwise textured, if desired. The surface of upper blank 1000 that contacts surface 106s of substrate 106, such as individual filamentous structures, may be formed with smooth (or textured) features of the surface 106s of substrate 106 upon which it contacts and is formed. Therefore, in some examples of the present invention, a surface (such as an inner surface or a bottom surface) of the shoe upper blank material 1000 may be smooth or textured to correspond to the texture on the surface 106s of the substrate 106, while the shoe upper blank material 1000 may be smooth or textured. An opposing surface (eg, an outer surface or a top surface) may have a texture corresponding to multiple overlapping layers of filamentous constructs.

As shown in Figure 3W, at this location on upper blank 1000, the filamentous formations of first layer 300 and second layer 350 (which may be substantially parallel and/or overlapping over a substantial portion of their length) span The shoe upper blank material 1000 generally extends in the medial-lateral direction (from the medial side toward the lateral side).

As is apparent from a comparison of Figures 3Q to 3W with 3W, the spacing between directly adjacent filamentous structures in a given layer generally becomes larger in the foot area prior to this exemplary upper blank 1000 than in the same layer. The spacing between the directly adjacent filamentous structures of the heel and/or midfoot of the shoe upper blank material 1000 is smaller. And, as shown in these figures, from (a) the filamentous structure of the third layer 400, the fourth layer 500, and the fifth layer 600 and (b) the sixth layer 700, the seventh layer 800, and the eighth layer The diamond-shaped opening formed by the intersection between the filamentous structures 900 becomes wider towards the forefoot area of the upper blank 1000 than the corresponding diamond-shaped openings provided at the rear heel and/or midfoot of the upper blank 1000. Small. These features provide improved support, durability, lockdown, and less stretch in the forefoot area of upper blank 1000 than at least some other areas. It can be further seen from the enlarged views of Figures 3Q to 3W that most of the space within the perimeter of the upper or upper blank material constitutes the intersection of the filamentous structures in the layers of the upper or upper blank material 1000. of open space. In at least some examples of the invention, the upper or upper blank 1000 may constitute at least 15% of the open space between the filamentous structures of the various layers, and in some examples, at least 25%, at least 30%, at least 40% %, or even at least 50% of the open space may exist between the filamentous structures in the upper or upper blank 1000 .

Many variations of the upper or upper blank 1000 structure and/or individual upper layers of filamentary construction are possible without departing from this invention. As some examples, the upper or upper blank 1000 may include more or fewer upper layers than the eight layers described above (e.g., from 2 to 24 layers, and in some examples, from 3 to 20 layers, from 4 to 16 layers). layers, from 5 to 12 layers, etc.). As an additional or alternative example, the laying order of the filamentary structural layers described above may be changed in some examples of the invention. Additionally or alternatively, while Figures 3D, 3F, and 3H show a serpentine configuration formed on the medial midfoot of the third layer 400, the fourth layer 500, and the fifth layer 600, respectively, and Figures 3J, 3L, and 3N Showing the serpentine configuration formed on the lateral midfoot of the sixth layer 700, the seventh layer 800, and the eighth layer 900 respectively, the upper or upper blank 1000 according to some examples of the present invention may include more or more Less of this same type of "snake" configuration, such as in one or more of the forefoot area, rear heel area, etc. More or fewer layers of upper blank 1000 may also include such "snake" configurations. The curved and serpentine configuration of the filamentous structural layers provides increased flexibility.

The filamentous construction materials disposed in various layers of a single upper or upper blank 1000 may be the same or different without departing from this invention. As some more specific examples, the upper or upper blank and/or individual layers thereof may have one or more of the following properties or characteristics: (a) filaments on all layers of the upper or upper blank The construction materials may be the same material, (b) the filamentous construction materials in one layer of the upper or upper blank may be different from the filamentous construction materials in one or more other layers of the upper or upper blank, (c) the filamentous structural material in each layer of the upper or upper blank may be different, (d) the filamentous structural material in all layers of the upper or upper blank may be the same color, (e ) The color of the filamentous structures in one layer of the upper or upper blank may be different from the color of the filamentous structures in one or more other layers of the upper or upper blank, (f) In the upper or upper The filament-like structures in each layer of the blank material may be of different colors, (g) the filament-like structures in one or more layers of the upper or upper blank material may be made of transparent or translucent materials, (h) in The filamentous structures in one or more layers of the upper or upper blank (and optionally in each layer of the upper or upper blank) may be made of a thermoplastic material, such as a thermoplastic polyurethane material, (i ) the filamentous structures in one or more layers of the upper or upper blank (and optionally in each layer of the upper or upper blank) may be made of a substantially non-absorbent material, (j) The filamentous structures in one or more layers of the upper or upper blank (and optionally in each layer of the upper or upper blank) may be made of a hydrophobic material, (k) in the upper or The filamentous structures in one or more layers of the upper blank (and optionally in each layer of the upper or upper blank) may be formed by materials that can be fused (e.g., in an adhesiveless manner) such as through solid deposition modeling techniques. (l) The filamentous structural materials on all layers of the upper or upper blank may have the same diameter, width, and/or thickness (or other dimensions), and/or ( m) The filamentous structural material in one layer of the upper or upper blank may be in the same diameter, width, and/or thickness ( or other dimensions). In some examples of the present invention, the upper or upper blank material (eg, two or more layers thereof collectively) can produce a moiré effect, as shown in Figures 1 and 3A to 3P.

As described above, in at least some examples of the present invention, one or more of the respective upper layers (e.g., first layer 300, second layer 350, third layer 400, fourth layer 500, fifth layer 600, The sixth layer 700, the seventh layer 800, and/or the eighth layer 900) may be formed as a continuous path of extruded filamentous structures. For example, in some examples of the present invention, the material may be extruded by first extruding at one location on an individual upper layer and continuously extruding material (including all necessary turns through the extruder nozzle 104/head) until the entire layers (such as in the form shown in one or more of FIGS. 3A, 3B, 3D, 3F, 3H, 3J, 3L, and 3N) to form the entire upper layer (as shown in FIG. 3A (first layer 300), FIG. 3B (second layer 350), Figure 3D (third layer 400), Figure 3F (fourth layer 500), Figure 3H (fifth layer 600), Figure 3J (sixth layer 700), Figure 3L (seventh layer 800), each of one or more of FIG. 3N (eighth layer 900)). However, this continuous extrusion path (with only one start and one end in extruding an entire layer) is not necessary. Rather, in at least some examples of the present invention, individual upper layers (e.g., similar to Figures 3A, 3B) may be formed in a discontinuous manner (e.g., with two or more pairs of extrusion start/stop actions for each individual layer) , 3D, 3F, 3H, 3J, 3L, and 3N). The extruder nozzle 104/head can be moved between the start and end points of the extrusion (while stopping the extrusion) to another desired position of the upper layer, so that the extrusion path segment of the layer can start at any desired position/ end.

In addition, FIGS. 3A to 3P illustrate each of the individual first layer 300 , second layer 350 , third layer 400 , fourth layer 500 , fifth layer 600 , in the upper or upper blank 1000 shown here. The sixth layer 700 , the seventh layer 800 , and the eighth layer 900 include individual path segments throughout each of the lateral rear heel, lateral midfoot, forefoot, medial midfoot, and medial rear heel. This is not required. More specifically, if desired, according to some examples of the present invention, an individual upper layer (e.g., first layer 300, second layer 350, third layer 400, fourth layer 500, fifth layer 600, sixth layer One or more of layer 700, seventh layer 800, and/or eighth layer 900) need not extend within and/or throughout all of the described areas. As some more specific examples, if desired: (a) one or more layers of the upper may be present only in the forefoot area of the overall upper; (b) one or more layers may be present only in the lateral midfoot area of the overall upper and/or in the medial midfoot area; (c) one or more layers may be present in one or both of the forefoot area of the overall upper and the lateral midfoot area and/or medial midfoot area; (d) may be omitted One or more layers in one or both of the lateral heel area and/or the medial heel area; (e) only a small amount of filamentous structures may be present in some portions or areas of an individual layer, etc. Selective inclusion of filamentous structures in less than all areas of the upper layer may allow selective control of properties in that area of the overall upper or upper blank (e.g., control of breathability, stretch, permeability, locking, etc. wait). When one or more layers are omitted in an individual region or region, there is no need to continuously extrude the filamentous structural layers contained in that individual region or region during the overall upper manufacturing process. For example, if desired, a distinct region or region of the upper or upper blank may include first layer 300, second layer 350, fourth layer 500, sixth layer 700, and seventh layer 800 (or a combination of any desired number and/or combination, including layers with different paths than the specific examples shown).

Figures 3A to 3P further show an example of upper layers laid out in a filamentous structure in a specific order, namely first layer 300, then second layer 350, then third layer 400, then fourth layer 500, then fifth layer 600, then the sixth layer 700, then the seventh layer 800, then the eighth layer 900. The order in which the layers are laid affects the characteristics and/or properties of the overall upper or upper blank 1000 . For example, if a layer with a larger filament spacing is laid closer to the inside of the upper and a layer with a smaller filament spacing is laid near the outside of the upper, it is different than having a layer with a larger filament spacing closer to the shoe. This may enhance the ability of the overall upper to escape water (or other substances) and/or resist the ingress of water (or other substances) within and/or within the upper, compared to an upper formed of the same layer (outside of the upper). Changing the order of the layers will also affect the zoning or overall performance of the upper (such as affecting locking, directional stretch, breathability, permeability, etc.). By changing the order of the layers, the intersection positions of different layers can be changed and/or changed, and thus the blending of one layer to another can be changed and/or changed to different locations and/or locations.

As noted above, an upper blank 1000 or upper component constructed from one or more layers of extruded filamentary construction of the types described above may be joined to one or more other upper components if desired. 4A-4C illustrate filamentous structures 1102, 1104, 1106, 1108 of a first upper component 1100 with one or more layers of extruded filamentary structures being joined to another second upper component 1110 (e.g., by Examples of adhesives or cements 1112). The upper component 1100 based on the extruded filamentary structure can be made of one or more layers of extruded filamentary structure, such as one of the plurality of layers, which includes each of the above-mentioned first layer 300, second layer 350, third layer 400, Any one or more of the fourth layer 500 , the fifth layer 600 , the sixth layer 700 , the seventh layer 800 , and/or the eighth layer 900 . The first upper component 1100 may be any desired type of upper component, including upper components known and used in the conventional footwear art, such as fabrics, textiles, elastic materials, knitted components, textile components, leather (natural or synthetic). ), thermoplastic materials, thermoplastic polyurethane, other polymer materials, etc. The extruded filament-based first upper component 1100: (a) can be positioned outside the other second upper component 1110 toward the outside of the footwear and away from the wearer's foot (FIG. 4A); (b) Can be located on the inside of other second upper components 1110 facing the interior of the footwear and proximate (and optionally adjacent or contacting) the wearer's foot (FIG. 4B); and/or (c) can be located on other The inside and outside of the second upper component 1110 (Fig. 4C). Additional second upper components 1110 may provide additional support where desired (e.g., heel tab, toe box, structural support, shape support, lacing-engaged support with instep opening 1012, structure for engaging sole components, etc.) support, soft foot contact surfaces (such as around the ankle opening 1014, as a "tongue" piece across the foot opening 1012), support for engaging another footwear component, etc. The combined first upper component 1100/second upper component 1110 may be incorporated into an overall footwear structure, as discussed in detail below.

However, Figures 5A-5C illustrate extruded filamentary structures by directly fusing (or fuse bonding) the filamentary structure of the first upper component 1100 with material of another second upper component 1120. The first upper component 1100 is joined to another second upper component 1120 in an adhesive-free manner. Such combined first upper component 1100/second upper component 1120 may include: (a) a first upper component 1100 that includes a first filamentous construct 1102 formed to include a first material (Figs. 5A-5C At least one first layer of four filamentous structures 1102, 1104, 1106, and 1108) optionally includes a first plurality of non-intersecting spaced path segments of filamentary structures, wherein the first extruded filamentary structure has a few a width dimension of 3 mm wide (and in some examples, less than 2 mm wide, less than 1 mm wide, or even less than 0.75 mm wide); and (b) a second upper component 1120 that includes at least a portion A fabric unit formed from a fusible material (any type described above for second upper component 1110, such as fabric, textile, elastic material, thermoplastic material, etc.). The first upper component 1100 based on the extruded filamentary structure can be made of one or more layers of extruded filamentary structure, for example, including the first layer 300, the second layer 350, the third layer 400 and the fourth layer similar to the above. 500, the fifth layer 600, the sixth layer 700, the seventh layer 800, and/or one of the eighth layer 900. In this configuration, the fusible material of the second upper component 1120 is fused to the filamentous formations 1102, 1104, 1106, and 1108 of the first upper component 1100. If necessary or desired, heat and/or pressure may be applied to the combined first upper component 1100/second upper component 1120 to fuse the filament-containing first upper component 1100 to the fabric unit second upper component Part 1120. The fusion between the first upper component 1100 and the second upper component 1120 may be the polymerization and seamless connection of the material of one or more filamentous structures 1102 to 1108 and the fusionable material of the second upper component 1120 of the fabric unit. result.

Figures 5A-5C illustrate filamentous structures 1102, 1104, 1106, 1108 of a first upper component 1100 on which one or more layers of extruded filamentary structures are based, and a second upper component including a fusible material as a fabric element. Example of 1120 joining. The extruded filament-based first upper component 1100: (a) can be positioned outside the other second upper component 1120 toward the outside of the footwear and away from the wearer's foot (FIG. 5A); (b) Can be located on the inside of other second upper components 1120 facing the interior of the footwear and proximate (and optionally adjacent or contacting) the wearer's foot (FIG. 5B); and/or (c) can be located on other The inside and outside of second upper component 1120 (Fig. 5C). Additional second upper components 1110 may provide additional support where desired (e.g., heel tab, toe box, structural support, shape support, lacing-engaged support with instep opening 1012, structure for engaging sole components, etc.) support, soft foot contact surfaces (such as around the ankle opening 1014, as a "tongue" piece across the foot opening 1012), support for engaging another footwear component, etc. The combined first upper component 1100/second upper component 1120 may be incorporated into an overall footwear structure, as discussed in detail below.

5D-5F provide examples of ways in which fusible materials may be incorporated into the textile unit second upper component 1120. For example, as shown in FIG. 5D , the fabric unit 1120 may be formed into a woven, knitted, or nonwoven structure, wherein at least one strand (eg, yarn) of the second upper component 1120 of the fabric unit is made of a fiber that is compatible with the second upper component 1120 . An upper component 1100 is made of one or more of the filamentous structures fused to a fusible material. In Figure 5D, one color of yarn 1122 is of a traditional fabric material (eg, made of polyester, cotton, elastomeric materials, etc.) and the other color of yarn 1124 is made of the type described above for fusible fabrics in a filamentous construction. The materials described may be made of fused materials, such as thermoplastic polyurethane materials or other thermoplastic materials. In this configuration, the yarn 1124 may be fused directly to the filamentous structures 1102, 1104, 1106, 1108 of the first upper component 1100 on which the extruded filamentary structure is based.

As another option, as shown in Figure 5E, the textile unit second upper component 1120 may be formed from a woven, knitted, or nonwoven structure that includes at least one yarn of the textile unit structure second upper component 1120, consisting of are formed of: (a) strands 1132 made of conventional fabric materials (e.g., made of polyester, cotton, elastomeric materials, etc.) and (b) strands 1132 of the type described above for fusible materials in filamentous construction Strands 1134 of a fusible material such as a thermoplastic polyurethane material or other thermoplastic material are interwoven together. In this configuration, the fusible strands 1134 can be fused directly to the filamentous structures 1102, 1104, 1106, 1108 of the first upper component 1100 on which the extruded filamentary structure is based.

As yet another option, Figure 5F provides a cross-sectional view of yarns or strands that may be used to make the second upper component 1120 of a fabric unit (eg, a woven, knitted, or nonwoven structure). The strands or yarns are formed as coaxial units over at least a portion of their axial length and include: (a) an inner core 1142 made of conventional fabric materials (e.g., polyester, cotton, elastomeric materials, etc.), and coated with (e.g., coextruded or otherwise formed with) (b) made of a fusible material of the type previously described for fusible materials in a filamentous construction, such as a thermoplastic polyurethane material or other thermoplastic material. The outer coverings 1144 are intertwined. In this configuration, the fusible outer cover 1144 may be fused directly to the filamentous constructs 1102, 1104, 1106, 1108 of the first upper component 1100 on which the extruded filamentous construction is based.

Figures 6A-6F illustrate a first upper component 1100 of a conventional fabric unit (or other footwear component) and/or a second shoe wherein a fabric unit includes a fusible material (of the type described above in conjunction with Figures 5D-5F). An example of a manner in which upper component 1120 may be joined together with a multi-layer fusible first upper component 1100 (of the type described above in connection with Figures 1A-3W). First, a shoe upper blank 1200 including one or more layers of extruded filamentary structures formed as described above (e.g., through solid deposition molding technology, into a continuous path, with a plurality of non-intersecting path segments, etc.) . Figure 6A shows the four layers before forming the upper blank mid-material 1200 to include the filamentary structure as described above, the first layer 300, the second layer 350, the third layer 400, and the fourth layer 500. For example, it can be the same as above. way formed. Any desired number of layers of filamentary structures and any desired routing and configuration of filamentary structures may be provided as upper blank 1200 without departing from the present invention (including one or more filamentary structure-based layers and/or the above. any individual layer and/or combination of layers).

Once the desired upper blank 1200 has been prepared including one or more filamentary construction layers on the extruder base 106 (eg, by extrusion, solid deposition molding, etc.), a release liner can be applied 1202, for example to cover a portion of the top surface of the upper blank midsole 1200 (e.g., a portion of the first layer extending inwardly from the peripheral edge of the first layer) may be covered with a release liner 1202, such as a portion surrounding one or both sides of the instep opening. , a portion around one or both sides of the ankle opening, a portion around the bottom edge of the upper to the sole structure, etc.). Release liner 1202 may be made of paper, plastic, or any type of material as long as release liner 1202 is not permanently affixed to the filamentous construction material that will be included in the upper component in a subsequent step.

After the release liner 1202 is placed, one or more additional layers of the filamentous construct may be extruded to form one or more additional layers of the upper component. For example, as shown in FIG. 6B , the fifth layer 600 , the sixth layer 700 , the seventh layer 800 , and/or the eighth layer 900 may be extruded into the release liner 1202 and the upper midsole 1200 (which may including the above-mentioned first layer 300, second layer 350, third layer 400, and/or fourth layer 500). In the example shown here, one or more additional materials are extruded to form an extruded filamentous construction of one or more additional layers, optionally including an additional plurality of non-intersecting spaced path segments in individual layers. Additional extruded filamentous constructs may have any of the dimensions described above and/or other filamentary construct characteristics. The additional layer extrusion step of this example may include: (a) coating a first portion of the additional filamentary construct layer onto release liner 1202 such that release liner 1202 extends over the previously extruded filamentary construct (in the upper) 1200) between the first portion of the additional filamentary construct layer and the first portion of the additional filamentary construct layer, and (b) between the fusion of the additional layer of filamentary constructs at the location where the most recently extruded filamentary construct layer contacts the previously extruded filamentary construct layer. The second portion is to the second portion of the previously extruded filamentous construct (in upper midsole 1200). In this manner, the additional filamentary structural layer applied after release liner 1202 is set will connect (in an adhesive-free manner) to the previously extruded filamentary structural layer away from release liner 1202 to provide An integrated shoe upper component (such as an integral shoe upper component, similar to the above-mentioned shoe upper blank material 1000).

Once all desired additional filamentary structural layers have been extruded and connected to the previously extruded filamentary structural layers of upper midsole 1200, there is a combined first upper component 1210 and release liner 1202 combination as shown in Figure 6C shown in . At this time, one or more of the filamentous structural layers of the first upper component 1210 are located below the bottom surface of the release liner 1202, and one or more of the filamentous structural layers of the first upper component 1210 are located below the release liner. 1202 above the top surface. At this point, the first upper component 1210 and the release liner 1202 can be removed from the extruder base 106 and the lower filamentous structural layers of the first upper component 1210 (e.g., first layer 300, second layer 350, third layer 400, fourth layer 500) and the higher filamentous structural layers of the first upper component 1210 (e.g., fifth layer 600, sixth layer 700, seventh layer 800, eighth layer 900) (Location of release liner 1202) Remove release liner 1202. Due to the presence of the release liner 1202, the lower filamentous structural layers of the first upper component 1210 (eg, the first layer 300, the second layer 350, the third layer 400, and the fourth layer 500) will be in the release liner 1202. The higher filamentous structural layers (eg, fifth layer 600, sixth layer 700, seventh layer 800, eighth layer 900) that are not affixed to the first upper component 1210 remain where they once were (although all of the first layer 300, The second layer 350, the third layer 400, the fourth layer 500, the fifth layer 600, the sixth layer 700, the seventh layer 800 to the eighth layer 900 can be secured together in their "second portion" where there is no release Pad 1202). In other words, the presence and removal of release liner 1202 creates a "pocket" between the layers of first upper component 1210 .

At this point, as shown in Figure 6D, another upper component (such as a fabric similar to those described above, second upper components 1110 and 1120) can be placed in the pocket formed between the layers of first upper component 1210 ( with release liner 1202) removed. The second upper component 1110 may be joined to the first upper component 1210 via adhesive, as described above in connection with FIG. 4C . Alternatively, when the second upper component 1120 includes a fusible material (such as a fabric unit of the type described above in connection with Figures 5D-5F), the second upper component 1120 may be joined to the first upper in an adhesive-free manner. Component 1210, for example, by fusing the fusible material of second upper component 1120 with the extruded filamentary construction material of first upper component 1210. This action may place and position the second upper component 1120 between the individual layers of the first upper component 1210, such as shown in the cross-sectional view of Figure 5C. If desired, this fusion step may include, for example, applying heat and/or pressure to the combined second upper component 1120/first upper component 1210, such as in the form shown in Figure 6E. The second upper component 1120 (and/or the first upper component 1210 ) may be trimmed, if necessary, combined with other upper components, and/or otherwise processed, if necessary, such as to prepare it for incorporation into footwear. in the structure. Although Figures 6A-6E show the second upper component 1110/1120 as an intermediate layer of the filament-based first upper component 1210, this is not required. Rather, the second upper component 1110/1120 may be positioned between any desired filamentous construction layers of the first upper component 1210 without departing from the present invention (e.g., between layers closer to the interior of the upper and /or between layers closer to the outside of the upper).

Second upper components 1110 and 1120 may form any desired portion or proportion of the footwear upper structure without departing from this invention. As some more specific examples, second upper components 1110 and 1120 may provide or overlap less than 50% (and in some examples, less than 40%, less than 30%, less than 20%, less than 10%) The total surface area of the first upper component 1210 (the term "total surface area" as used herein in this context means the complete area defined within the outermost perimeter of the upper component 1210, including all areas of the first upper component 1210 The open spaces defined between individual filamentous structures). The second (eg, fabric) upper components 1110 and 1120 may form any desired portion of the overall upper construction, including one or more of the following: the instep/tongue portion of the upper, the upper portion of the upper, the lacing of the upper The band joint, the foot receiving opening of the upper, the collar of the upper, the rear heel joint of the upper, etc.

Figures 7A-7C illustrate an exemplary article of shoe 2000, including an upper 2002 having at least a portion of an upper blank 1000 formed into a multi-layered filamentous construction type of the type described above. As shown, upper 2002 includes combined second upper components 1110 and 1120/first upper component 1210, such as the type described above in connection with Figures 6A-6E. Second upper components 1110 and 1120 may be coupled to a filament-based component (eg, upper blank 1000) in any desired manner, including those described above in connection with Figures 4A-6E. As shown in these Figures, the second upper components 1110 and 1120 of this example are one or more fabric elements that cover the lacing engagement area and instep area of upper 2002 (e.g., forming a "tongue-like" area of upper 2002 unit and/or upper portion), around the foot insertion opening 2006 (e.g., to provide a collar around the ankle for added comfort), and down around the rear heel portion of upper 2002 (e.g., to provide a collar around the heel). Provides comfort) extension.

Both the second upper components 1110 and 1120 and the filament-based first upper component 1210 of this exemplary embodiment include openings and/or other structures for engaging laces 2008 . Alternatively, only one of the textile second upper components 1110 and 1120 and the filament-based first upper component 1210 may include lace engagement openings or structures, if desired. As another option or alternative, if desired, textile second upper components 1110 and 1120 may include lace-engaging openings or structures in one or more areas of upper 2002 with the filamentous construction being the base of the first Upper component 1210 may include lace engagement openings or structures in one or more other areas of upper 2002. If desired, when the filament-based first upper component 1210 engages the laces 2008, the laces 2008 may extend through the openings provided by the filament-based first upper component 1210 in the multi-layered upper. between individual filamentous structures of the structure.

Upper 2002 may be joined to sole structure 2004 in any desired manner, including conventional means known and used in the footwear art (eg, adhesives, mechanical connectors, seams, etc.). Any desired type of sole structure 2004 may be provided, including one or more portions of a sole structure as is known and used in the footwear art. In some examples of the present invention, sole structure 2004 may include lightweight foam or liquid-filled bladders (optionally made of hydrophobic, waterproof, and/or non-absorbent materials). Sole structure 2004 may also include track spikes, cleats, and/or other traction enhancing elements.

A footwear upper according to an example of the present invention includes an upper component (including upper blank 1000, first upper component 1210, and/or upper 2002) based on the above-mentioned type of extruded filamentary structure, Many desirable properties are available, especially for athletic footwear construction. In view of the large number of openings between the individual filamentous structures in the layer, the thin structure of the filamentary structures, and the relative reduced volume of the heavier material present, upper blank 1000, first upper component 1210, and/or Or the upper 2002 is made to be extremely light and/or breathable. As another potential advantage, as mentioned above, the filamentous constructs can be made from hydrophobic and/or substantially non-absorbent materials. Therefore, if upper 2002 is exposed to moisture during use, the filamentous structure can remove/repellent water, maintaining a lightweight condition. The ability to remain lightweight even in wet conditions may be further enhanced in the upper structure by any fabric-based upper components included in upper 2002 (such as second footwear components 1110 and 1120). (at least partially) made of hydrophobic materials and/or substantially non-water-absorbent materials (such as thermoplastic polyurethane materials and/or other thermoplastic materials and/or other hydrophobic and/or waterproof materials, which may be, for example, one or more of Figures 5D to 5F provided as fusible components) and/or if the sole structure 2004 is made (at least in part) of hydrophobic materials and/or substantially non-absorbent materials (such as thermoplastic polyurethane materials and/or other thermoplastic materials and/or or other hydrophobic and/or waterproof materials). When first upper component 1210 is formed at least partially into a multi-layered filamentous construction, many different colors and color combinations can be used to provide a variety of aesthetic and design opportunities, including creating a moiré effect, as shown in Figures 1 and 3A-3P .

Furthermore, extruded filamentary construction type structures and production methods allow for a seamless transition between upper structural properties that provide different functions and/or characteristics (e.g., between areas that provide increased support and lockdown and areas that provide improved flexibility). Seamless transitions between zones; seamless changes in breathability in different zones, etc., by changing filament structure size, spacing, materials, etc.). Additionally, the relatively uniform overall upper thickness of the multi-layered filamentous construction can provide varying stretch and/or breathability properties in different areas of the upper in a seamless, one-piece, and one-piece structure. As another potential advantage/feature, the upper blank 1000/first upper component 1210 can be formed from a multi-layer extrusion process without creating tensile stresses on the individual filamentous formations of the upper structure.

In the particular example described above, the filament-based upper component forms an upper component that substantially covers or surrounds the wearer's foot from the rear heel area, through the midfoot area, and to the forefoot area ( Such as shoe upper blank material). There may be other options in which the filament-based upper component (e.g., having any desired number of extruded layers, including from 1 to 20 layers, and in some examples, from 2 to 16 layers, 3 to 10 layers , 4 to 10 layers, or even 8 layers) forming one or more separate parts of the overall upper. 8A and 8B illustrate an article of footwear 3000 having such an upper 3002 engaged with a sole structure 3004. As shown in these figures, this example upper 3002 includes one or more fabric-based upper components 3002a and one or more extruded filament-based upper components 3002b (which may include the types described above. One or more layers of extruded filamentous structures). This example extruded filament-based upper component 3002b forms a lateral upper panel (FIG. 8A) and a separate medial upper panel (FIG. 8B). These extruded filament-based upper components 3002b may be joined to another fabric-based upper component 3002a in any desired manner, including any of the methods described above in connection with Figures 4A through 6E (including through adhesives and /or adhesive-free method).

As further shown in Figures 8A and 8B, in this illustrative example, fabric-based upper component 3002a and extruded filament-based upper component 3002b include openings and/or other structures for engaging laces 3008 . Alternatively, only one of the fabric-based upper component 3002a and the extruded filament-based upper component 3002b may include lace engagement openings or structures, if desired. As another option or alternative, if desired, the fabric-based upper component 3002a may include lace engagement openings or structures in one or more areas of the upper 3002, and the extruded filamentous construction may be used as the base shoe. Upper component 3002b may include lace engagement openings or structures in one or more other areas of upper 3002. If desired, when extruded filament-based upper component 3002b engages laces 3008, laces 3008 may extend through openings provided by extruded filament-based upper component 3002b in the multi-layer upper. between individual filamentous structures of the structure.

Fabric-based upper component 3002a may have any desired structure and/or may be made of any desired material without departing from the present invention, including conventional structures and/or materials known and used in the footwear art and/or The structure described above in conjunction with Figures 5A to 7C (including hydrophobic, waterproof and/or non-water absorbing materials). Sole structure 3004 may be any desired type of sole structure, including one or more components as are known and used in the footwear art. In some examples of the present invention, sole structure 3004 may include lightweight foam or liquid-filled bladders (optionally made of hydrophobic, waterproof, and/or non-absorbent materials). Sole structure 3004 may also include track spikes, cleats, and/or other traction enhancing elements.

Even if only a portion of upper 3002 is formed from extruded filament-based upper component 3002b, enhanced breathability and/or lightweight properties may still be achieved. The extruded filament-based upper component 3002b can be placed anywhere where enhanced breathability is needed or desired. To reduce weight, in the exemplary construction of Figures 8A and 8B, an upper similar to one made entirely of fabric-based upper component 3002a (i.e., fabric-based upper component 3002a extends through the medial and lateral midfoot area), using two extruded filamentous constructs as the base for upper component 3002b reduces the total weight of upper 3002 by approximately 24 grams. In some examples of the invention, the extruded filamentous construct-based upper component 3002b may form from 15% to 100% of the overall upper surface area, and in some examples, from 25% to 100% of the overall upper surface area. %, 35% to 100%, 59% to 100%, 60% to 100%, or even 75% to 100%.

If desired, as schematically illustrated in Figure 9, one or more of the upper layers (e.g., first layer 300, second layer 350, third layer 400, One or more of the fourth layer 500 , the fifth layer 600 , the sixth layer 700 , the seventh layer 800 , and/or the eighth layer 900 ) (for example, forming the shoe upper blank 1000 ) can be formed by extrusion/solid deposition The molding technique forms a footwear strobel component (or sock liner) 1020 along with one or more of the filamentous structural layers (optionally, as a continuum with one or more of the filamentous construction layers). part of the path). As shown in FIG. 9 , the Stauber component 1020 may be integrally formed with the upper blank 1000 , such as with one or more edges of the upper blank 1000 (e.g., at the lateral low perimeter edge, medial low perimeter edge, forefoot edge, one or more rear heel edges, etc.). Stauber component 1020 may be formed as a filamentous construction, such as having any of the properties, features, and/or options of filamentary constructions described above (e.g., having a grid or matrix structure, multiple layers, having intersecting/overlapping filamentary constructions) path segments, etc.). Once the upper/Stober combination 1040 is formed, the Stobe component 1020 may be folded at its entire edge with the upper blank 1000 and attached at its free peripheral edge 1020P to the peripheral edge 1000P of the bottom of the upper blank 1000 ( For example, by adhesive, by fusion, etc.). Stobbe component 1020 may be formed in two or more parts, such as at two or more separate locations along the peripheral edge 1000P of the upper. III. Conclusion
