Definitions

  • the present disclosure relates generally to sole structures for articles of footwear, and more particularly, to sole structures incorporating a chassis for accommodating a bladder assembly.
  • Articles of footwear conventionally include an upper and a sole structure.
  • the upper may be formed from any suitable material(s) to receive, secure, and support a foot on the sole structure.
  • the upper may cooperate with laces, straps, or other fasteners to adjust the fit of the upper around the foot.
  • Sole structures generally include a layered arrangement extending between a ground surface and the upper.
  • One layer of the sole structure includes an outsole that provides abrasion-resistance and traction with the ground surface.
  • the outsole may be formed from rubber or other materials that impart durability and wear-resistance, as well as enhance traction with the ground surface.
  • Another layer of the sole structure includes a midsole disposed between the outsole and the upper.
  • the midsole provides cushioning for the foot and may be partially formed from a polymer foam material that compresses resiliently under an applied load to cushion the foot by attenuating ground-reaction forces.
  • the midsole may additionally or alternatively incorporate a fluid-filled bladder to increase durability of the sole structure, as well as to provide cushioning to the foot by compressing resiliently under an applied load to attenuate ground-reaction forces.
  • Sole structures may also include a comfort-enhancing insole or a sockliner located within a void proximate to the bottom portion of the upper and a strobel attached to the upper and disposed between the midsole and the insole or sockliner.
  • Midsoles employing fluid-filled bladders typically include a bladder formed from two barrier layers of polymer material that are sealed or bonded together.
  • the fluid-filled bladders are pressurized with a fluid such as air, and may incorporate tensile members within the bladder to retain the shape of the bladder when compressed resiliently under applied loads, such as during athletic movements.
  • bladders are designed with an emphasis on balancing support for the foot and cushioning characteristics that relate to responsiveness as the bladder resiliently compresses under an applied load.
  • document US 2014/0075778 A1 discloses a sole structure for an article of footwear including an outsole component and a midsole component engaged with the outsole component.
  • the midsole component includes at least one opening or receptacle, at least one fluid-filled bladder system or foam system provided in the opening or receptacle, and/or a rigid plate system including one or more rigid plates overlaying the fluid-filled bladder or foam system(s).
  • the rigid plate(s) may be fixed directly to the midsole component or the rigid plate(s) may rest on the fluid-filled bladder(s) or foam somewhat above the surface of the midsole component when the sole structure is in an uncompressed condition.
  • Document US 2007/0119075 A1 discloses a fluid-filled chamber for an article of footwear.
  • the chamber may be incorporated into a sole structure of the footwear and includes a central area and a plurality of lobes extending outward from the central area.
  • the lobes are in fluid communication with the central area and are formed from a first surface, a second surface, and a sidewall.
  • the sidewall joins with the first surface with the second surface to seal the fluid within the chamber, but no internal connections are generally utilized to join interior portions of the first surface with interior portions of the second surface.
  • the fluid within the chamber may be air at a pressure that is approximately equal to an ambient pressure.
  • document US 2014/196308 A1 shows an article of footwear that includes a sole structure comprising a midsole and an outsole.

  • the midsole recesses are formed to align with the outsole recesses to form a plurality of separately distinct fluid-filled chambers.
  • Example configurations will now be described more fully with reference to the accompanying drawings.
  • Example configurations are provided so that this disclosure will be thorough, and will fully convey the scope of the disclosure to those of ordinary skill in the art. Specific details are set forth such as examples of specific components, devices, and methods, to provide a thorough understanding of configurations of the present disclosure. It will be apparent to those of ordinary skill in the art that specific details need not be employed, that example configurations may be embodied in many different forms, and that the specific details and the example configurations should not be construed to limit the scope of the disclosure.
  • first, second, third, etc. may be used herein to describe various elements, components, regions, layers and/or sections. These elements, components, regions, layers and/or sections should not be limited by these terms. These terms may be only used to distinguish one element, component, region, layer or section from another region, layer or section. Terms such as “first”, “second”, and other numerical terms do not imply a sequence or order unless clearly indicated by the context. Thus, a first element, component, region, layer or section discussed below could be termed a second element, component, region, layer or section without departing from the teachings of the example configurations.
