摘要:
A fluid-filled chamber (40) for an article of footwear and a method for manufacturing the chamber are disclosed. The chamber may be incorporated into a sole structure (30) of the footwear and includes a central area (41) and a plurality of lobes (42a-42e) extending outward from the central area. The lobes are in fluid communication with the central area and are formed from a first surface (45), a second surface (46), and a sidewall (47). 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.

A cushioning component (40) for an article of footwear (10) is disclosed that includes a fluid-filled chamber (50) and a covering element (60) extending over a portion of the chamber. The chamber is devoid of internal connections, and the fluid within the chamber may be at a pressure that is substantially equal to an ambient pressure. The chamber defines a plurality of lobes (56a-56f), and the cushioning element includes a plurality of inserts (63) that extend between the lobes. The inserts are elongate structures that decrease the compressibility of peripheral portions of the cushioning component.
摘要:
An article of footwear (10) having an 'upper (20) and a sole structure (30) secured to the upper. The sole structure includes a first chamber (40) and a second chamber (50) that each enclose a fluid. The first chamber and the second chamber both define a plurality of projections and depressions. At least a portion of the projections of the first chamber are located within the depressions of the second chamber, and at least a portion of the projections of the second chamber are located within the depressions of the first chamber. In some configurations, each of the first chamber and the second chamber may form portions of upper and lower surfaces of a pneumatic component. In addition, colors of the first chamber and the second chamber may be selected such that the colors combine at an interface of the first chamber and the second chamber.
摘要:
A method of manufacturing a sole structure for an article of footwear, the method comprising: defining a plurality of depressions in a first polymer layer; locating a volume of a polymer foam material within the depressions to partially fill the depressions, at least one of the depressions receiving a different volume of the polymer foam material than the other depressions; expanding the polymer foam material to substantially fill the depressions; and securing a second polymer layer to the first polymer layer to seal the polymer foam material within the depressions.
摘要:
An article of footwear (10) may have a sole structure (30) with a chamber (50), a plate (40), and an outsole (60). The chamber encloses a fluid and has an upper surface and an opposite lower surface. The plate is positioned adjacent to the upper surface and has a plurality of projections that extend into indentations in the chamber. The outsole may be positioned adjacent to the lower surface and may have a plurality of projections that extend into indentations in the chamber. In some manufacturing processes for the sole structure, the plate and outsole may be located within a mold, and the chamber may then be shaped by surfaces of the plate, outsole, and mold.

An article of footwear may have a sole structure with a chamber (50a), a plate (40a), and an outsole (60a). The chamber encloses a fluid and has an upper surface and an opposite lower surface. The plate is positioned adjacent to the upper surface and has a plurality of projections that extend into indentations in the chamber. The outsole may be positioned adjacent to the lower surface and may have a plurality of projections that extend into indentations in the chamber. In some manufacturing processes for the sole structure, the plate and outsole may be located within a mold (110,120), and the chamber may then be shaped by surfaces of the plate, outsole, and mold.

A fluid -filled chamber (240) for an article of footwear and a method for manufacturing the chamber are disclosed. The chamber may be incorporated into a sole structure (230) of the footwear and includes a central area and a plurality of lobes (242a-242f ) extending outward from the central area (241). The lobes are in fluid communication with the central area and are formed from a first surface (245), a second surface (246), and a sidewall (247). 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. The- first surface defines a protrusion (244a) extending outward from the cental area.

A fluid-filled bladder is disclosed that may be incorporated into footwear or other products. The bladder includes a sealed outer barrier, a foam tensile member, and a fluid. The tensile member is located within the barrier and bonded to opposite sides of the barrier. The fluid is also located within the barrier, and the fluid is pressurized to place an outward force upon the barrier and induce tension in the tensile member.
