- Embodiments utilizing braided uppers can include provisions to help provide additional structure to the upper, in some embodiments, for example, an article may include one or more additional material portions that are bonded or otherwise attached to specific portions of the braided upper in order to enhance various characteristics of the upper. For example, these material portions may be used to increase strength and durability, provide stretch resistance at certain locations of the upper and facilitate the joining of other components with the braided structure.
- overlay portion refers to any portion of material that is attached to a surface of a braided structure, such as a braided upper.
- an overlay portion is comprised of a distinct material from the strands of the braided structure.
- an overlay portion may have substantially different material characteristics from the strands of the braided structure.
- an overlay portion may resist stretching in comparison to a corresponding portion of a braided structure.
- an overlay portion may be formed of any material.
- Exemplary materials include, but are not limited to: fabrics (including woven and non-woven fabrics), leathers (including natural and synthetic leathers), polymer materials, as well as other kinds of materials.
- one or more overlay portions may be made of thermoplastic polyurethane (TPU).
- article 100 may be associated with overlay component 140.
- Overlay component 140 may be further comprised of several different overlay portions, including a first overlay portion 150, a second overlay portion 152 and a third overlay portion 154.
- Each overlay portion may be provided at a specific location on upper.
- first overlay portion 150 may be associated with fastening region 124 of upper 102.
- second overlay portion 152 may be associated with opening 120.
- third overlay portion 154 may be associated with heel portion 14 as well as portions of both lateral side 16 and medial side 18 of upper 102.
- first overlay portion 150 extends along the edges of fastening region 124.
- first overlay portion 150 includes a first section 181 that is associated with lateral fastening edge 128 of fastening region 124.
- first overlay portion 150 includes a second section 182 that is associated with medial fastening edge 127 of fastening region 124.
- an intermediate section 183 runs along a forward most edge 129 of fastening region 124 and joins first section 181 and second section 182 of first overlay portion 150.
- first overlay portion 150 may form, or form part of, the lateral and medial eyestays for upper 102.
- first overlay portion 150 may facilitate the attachment of upper 102 with fastening member 160.
- the use of overlay portions along the edges of fastening region 124 may help to more evenly distribute the tensioning forces applied by fastening member 160 to upper 102.
- first overlay portion 150 may help finish the braided structure of upper 102 along lateral fastening edge 126, medial fastening edge 127 and forward most edge 129 of fastening region 124.
- first overlay portion 150 may help to bond, fuse or otherwise hold the ends of the strands in place in order to prevent unraveling of the strands along these edges.
- second overlay portion 152 extends along the edges of opening 120.
- second overlay portion 152 is associated with opening edge 195.
- second overlay portion 152 is substantially continuous with first overlay portion 150, such that all of the edges of upper 102 associated with opening 120 and/or the opening at fastening region 124 are covered by first overlay portion 150 or second overlay portion 152.
- This arrangement helps to finish opening edge 195 by bonding any open strands to second overlay portion 152.
- second overlay portion 152 may help reinforce opening 120, so that the braided structure in the vicinity of opening 120 may not be overly stretched. Such reinforcement may be especially useful at opening 120, since opening 120 may undergo a great deal of pulling and other stress as a user inserts and/or removes his or her foot.
- third overlay portion 154 may include a first section 171 that extends along lateral side 16 and a second section 172 that extends along medial side 18 of upper 102. Additionally, a third section 173 of third overlay portion 154 may extend beneath (e.g., on a lower side of) upper 102 at heel portion 14. In some embodiments, third section 173 joins first section 171 and second section 172 so that third overlay portion 154 wraps continuously around the sides and bottom of upper 102.
- first section 171 of third overlay portion 154 extends from, and is continuously formed with, first section 181 of first overlay portion 150. Additionally, in some embodiments, second section 172 of third overlay portion 154 extends from, and is continuously formed with, second section 182 of first overlay portion 150. Because third overlay portion 154 may act to reduce stretching along its length, this configuration may help increase support under the heel by resisting stretching of the upper between first overlay portion 150 (at the top of the foot) and the lower side 199 (see FIG. 8) of heel portion 14.
- FIG. 3 illustrates an enlarged view of a portion of article 100 where some strands may be bonded to a second overlay portion 152.
- some strands 304 may be disposed against inner surface 302 second overlay portion 152.
- strands 304 may form part of a closed woven edge 305 of upper 102 that lacks any loose or free ends of strands.
- strands 304 may be bonded to second overlay portion 152 to reinforce the continuously woven section of the braided structure.
- some strands 470 may be configured with loose or free ends 472.
- open ends 472 may be secured to overlay portion 452 in order to keep strands 470 in place and help prevent strands 470 from loosening or unraveling.
- an overlay portion may be used to retain the loose or free ends associated with the edge of a braided structure. Such an arrangement may provide a means of finishing cut edges of the braided structure, or any edges that include loose or free ends that might unravel.
- the arrangement described here provides an overlay portion that may act to reinforce the edge of the braided structure at opening 120. This may help reduce stretching of upper 102 at opening 120, in order to preserve the structural integrity of upper 102. in addition, second overlay portion 152 may help secure any loose or open ends of the braided structure to prevent fraying of the ends and/or unraveling of the braided structure.
- Exemplary materials used for bonding can include any known adhesives, melts, resins or other bonding agents.
- FIG. 5 illustrates an isometric view of article 100, including an enlarged schematic cross-sectional view of a portion of first overlay portion 150 and fastening member 160.
- first overlay portion 150 includes a plurality of eyeiets 400.
- plurality of eyeiets 400 including eyelet 402 shown in the enlarged cross-section, are openings in first overlay portion 150 that are configured to receive portions of fastening member 160.
- strands of upper 102 are indirectly secured to fastening member 180 via eyelets in first overlay portion 400.
- strands 410 are seen to be secured directly to first overlay portion 150, while fastening member 160 is secured through plurality o eyeiets 400 in first overlay portion 150.
- This configuration may distribute forces imparted by fastening member 160 more evenly across the braided structure of upper 102. This may prevent fastening member 180 from tugging too much on a particular strand, for example, thereby facilitating better comfort and fit of article 100 on a foot.
- FIGS. 6 and 7 illustrate two possible configurations for strands in the vicinity of eyelets on an overlay portion.
- one or more strands may extend around an eyelet, thereby acting to reinforce the eyelet.
- first strand 512 and second strand 514 wrap around first eyelet 502 and second eyelet 504, respectively. This may have the effect of reinforcing first eyelet 502 and second eyelet 504, as well as providing a more direct transfer of tension between fastening member 160 and the braided strands of upper 102.
- first eyelet 502 and second eyelet 504 are not surrounded by any strands of the upper.
- strands 610 are bonded to first overlay portion 150 without encircling first eyelet 502 and second eyelet 504.
- some eyelets may be surrounded or reinforced by strands while other eyelets may not be surrounded or reinforced.
- FIG. 8 illustrates a rear isometric view of upper 102, in which strands 130 of upper 102 are shown in phantom.
- third overlay component 156 is seen to wrap underneath a bottom side 199 of upper 102 at heel portion 14. In some cases, this configuration allows third overlay portion 156 to cradle the heel of the foot. Thus, this arrangement may provide further support for the heel of the foot when article 100 is worn by reducing stretching through heel portion 14.
- distinct overlay components may be used.
- distinct overlay components may be configured to intersect or overlap at predetermined portions of an upper. Such configurations of overlapping overlay components may provide a means for enhancing strength and stretch resistance over large portions of an upper, including, possibly, the entirety of the upper.
