[0003] This section provides background information related to the present application that is not necessarily prior art.

[0004] Footwear traditionally includes an upper and a sole structure. The upper is a foot support that fits over the sole structure. The upper may be formed from any suitable material for receiving, securing, and supporting the Working with laces, straps, or other fasteners to fit the upper around the foot The bottom of the upper, closest to the bottom of the foot, is attached to the sole structure. can be done. Summary of the Invention

[0005] The sole structure generally includes a layered structure that extends between the ground and the upper. One layer of the outsole provides abrasion resistance and traction with the ground. The rails may be made from rubber or other materials that provide durability and abrasion resistance. It also improves traction with the ground. Another layer of the sole structure is the outsole and the upper. The midsole is placed between the shoe and the ground. The midsole provides cushioning to the foot. This reduces the impact of the foot by damping ground-reaction forces. A section made from a polymer foam material that compresses elastically under an applied load to absorb The midsole may additionally or alternatively be formed to improve the durability of the sole structure. and compresses elastically under an applied load to dampen ground rebound forces. The sole may incorporate a fluid-filled chamber that provides cushioning to the foot by compressing the sole. The construction also includes a comfort enhancing insole or sole liner, the sole liner being Located in the gap near the bottom of the par, the stroble is attached to the upper The foam is placed between the midsole and the insole or sockliner.

[0006] Midsoles that use fluid-filled chambers are generally sealed or bonded and contain air or other The chamber is formed from two barrier layers of polymeric material that are pressurized with a fluid. , which changes the shape of the chamber when it compresses elastically under load, e.g., during exercise. A tension member may be incorporated within the chamber to hold the fluid in place. Generally, the fluid-filled chamber is Related to the balance of the ports and their response as the fluid-filled chamber compresses elastically under load However, the fluid-filled chamber is designed to provide cushioning properties that are consistent with the overall The fluid-filled chamber compresses to dampen ground-rebound forces but not to dampen foot-induced vibrations. Therefore, it is necessary to dampen the vibrations caused by the feet and ground reflections. Fluid-filled chambers provide acceptable cushioning for the foot while attenuating force. The sole is difficult to form. [Brief description of the drawings]

Additional layers such as a sole 216 or sock (FIGS. 3 and 4) may also be incorporated.

[0033] The fluid-filled chamber 300 is formed by the upper barrier layer 301 during the molding or heating process. (hereinafter "upper layer 301") and lower barrier layer 302 ("lower layer 302"). In some examples, the top layer 301 and the bottom layer 302 are made of one or more polymeric materials. The upper layer 301 and the lower layer 302 are bonded together around the periphery of the sole structure 200. 3 and 4. The upper layer 301 and the lower layer 302 are joined together to define a flange 306 (FIGS. 3 and 4). 302 is a portion between the outer side 18 of the sole structure 200 and the inner side 20 of the sole structure 200 They are joined together at various locations therebetween to define web region 308 (FIGS. 3 and 4).

[0034] In some embodiments, the fluid-filled chamber 300 includes a plurality of fluid-filled segments 31 1, 312, 313, 314, 315, 316, 317, 318, 319, 320, 32 1, 322, 323, and 324 (see FIG. 5), each of which is adapted to carry a pressurized fluid (e.g., Fluid-filled footwear 10 contains air (fluid-filled foam) and provides cushioning and stability to the foot while the footwear 10 is in use. The segments 311-324 are all fluidly coupled to each other, and the fluid-filled segments 311- 324 may have a different length than the other fluid-filled segments 311-324. The segments 311-324 are formed in the region of the sole structure 200, and the upper layer 301 and the lower layer 302 are separated from each other and are each for containing a pressurized fluid (e.g., air). Thus, the flange 306 and the web region 308 define the gap between the top layer 3 and the 3 corresponds to the area of ​​the fluid-filled chamber 300 where the bottom layer 302 and bottom layer 303 are bonded together. , cooperate to define the boundaries of each fluid-filled segment and seal the pressurized fluid therein. Thus, the fluid-filled segments 311-324 are located in the respective regions 12 of the sole structure 200. 14, 16 and spaced apart from each other by web regions 308. In other words, more fluid-filled segments 311-324 may be cooperatively The corresponding area of ​​the web region 308 may be bounded.

[0036] Each of the fluid-filled segments 311-324 has a substantially tubular cross-sectional shape and a chamber. Between the upper layer 301 and the lower layer 302 of the sole structure 200, In this manner, each fluid-filled segment may define a thickness extending substantially perpendicularly thereto. The thickness of the upper layers 302 is different from that of the upper layer 301. The distance that the fluid-filled segments 311-324 project away from each other is determined by the distance that the fluid-filled segments 311-324 project away from each other. At least two may define different thicknesses. For example, one or more fluid-filled segments 311-324 disposed in the heel region 16 may be associated with a thickness greater than the thickness associated with one or more fluid-filled segments

[0037] 311-324 disposed in the forefoot region 12. In some embodiments, at least two of the fluid-filled segments 311-324 extend along the outer side 18 of the sole structure 200, while at least two other fluid-filled segments 311-324 extend along the inner side 20 of the sole structure 200. Furthermore, some of the fluid-filled segments 311-324 extend between the outer side 18 of the sole structure 200 and the inner side 20 of the sole structure 200. For example, at least one of the fluid-filled segments 311-324 may extend continuously from one of the outer side 18 and the inner side 20 to the other of the outer side 18 and the inner side 20. Additionally or alternatively, one of the fluid-filled segments 311-324 extends from one of the outer side 18 and the inner side 20 to a distal end 5 that terminates at a position between the inner side 20 and the outer side 18. Here, the distal end 5 may taper in a direction toward the upper 100, i.e., toward the upper layer 302 of the fluid-filled chamber 300. In some examples, the fluid-filled chambers 300 are fluidly coupled to each other, penetrate each region 12, 14, 16, and include a serpentine shape defined by fluid-filled

[0038] segments 311-324 that extend between the outer side 18 and the inner side 20 of the While improving the functionality and cushioning provided by the sole, Improved by damping foot induced vibrations in response to ground reaction forces. Provides stability and support during forward motion, such as walking or running. The load on the sole structure 200 is cushioned to the foot by attenuating the ground rebound force. Some of the fluid-filled segments 311-324 are compressed to provide a Meanwhile, the other fluid-filled segments 311-324 retain their shape and are resistant to the ground repulsion. The present invention provides footwear 10 with stability and support characteristics that dampen foot vibrations upon initial impact. Can be given.

[0039] Further, one or more of the fluid filled segments 311-324 may be formed in the sole structure 2. 308 in different regions 12, 14, 16 to form a responsive cushion. For example, a fluid-filled segment in the heel region 16 may result in isolated regions of fluid filling. 311-314 are grounded in segments 311-314 around the periphery of the heel region 16 The initial impact of the rebound force is absorbed by the trampoline effect, 8 to provide responsive cushioning in the heel region 16 and to provide a fluid filled The padding segments 311-314 compress in succession, thereby providing a gradient response to the heel region 16. Provides a shaped cushion.

[0040] Additionally, the geometry of the fluid-filled segments 311-324 (FIG. 5) along the sole structure 200 The geometric shape and arrangement of the outsole 210 is such that the outsole 210 contacts the ground from the heel region 16 to the forefoot region 12. 4. Provides traction between the outsole 210 and the ground during forward rolling motion due to engagement with the In addition, the outsole 210 can be formed on the outer side 18 and the inner side 2. 0 to the outside side 18 and the inside side 20 for ground engagement. The same is true during lateral motion.

[0041] FIG. 2 illustrates an exploded view of the article of footwear 10 of FIG. 1. The stroble 220 includes a bottom surface 222 and a and a foot bed 224, the foot bed 224 being supported by a bottom surface 222 of the strobe 220.

The upper surface 244 of the midsole 240 is disposed on the opposite side to the bottom surface 242 of the midsole 240. 220 and extends around the periphery of the upper 100. The bottom surface 242 of the midsole 240 interfaces with the top surface 301 of the fluid-filled chamber 300. Thus, the midsole 240 acts as an intermediate layer, and the upper surface 2 44 to the bottom surface 222 of the upper 100 and / or the strobe 220. Thus, by further bonding the bottom surface 242 to the top layer 301 of the fluid-filled chamber 300, Thus, the top layer 301 of the fluid-filled chamber 300 is indirectly attached to the upper 100. This allows the sole structure 200 (e.g., the outsole 210, the fluid-filled chamber 3 00, and midsole 240 are fixed to the upper 100. The midsole 240 reduces the extent to which the upper layer 301 extends over the periphery of the upper 100. 3, thereby reducing the likelihood of the top layer 301 becoming detached from the upper 100. This increases the durability of the footwear 10 when used for long periods of time.

[0043] Additionally, the midsole 240 may be configured to support and cushion the foot. In some examples, the midsole may be contoured to match the profile of the bottom of the midsole. The ball 240 provides cushioning to the foot by dampening ground rebound forces. from a slab of one or more polymeric foam materials that compress elastically under an applied load. In some embodiments, the volume of the fluid-filled chamber 300 under an applied load is Compression by multiple fluid-filled segments 311-324 provides responsive cushioning, while The compression by the midsole 240 under an applied load provides soft cushioning. Thus, the fluid-filled segments 311-324 and the midsole 240 cooperate to This allows the footwear article 10 to have gradient cushioning that changes as the load applied to it changes. (i.e., the greater the load, the more the fluid-filled segments 311-324 are compressed and Therefore, the footwear 10 is more responsive.

[0044] The upper layer 301 of the fluid-filled chamber 300 faces the bottom surface 242 of the midsole 240. The top layer 301 is attached (e.g., bonded and joined) by a molding process or a thermal The midsole 240 is formed from one or more polymeric materials in a molding process. The housing includes an outer periphery extending upwardly therefrom.

[0045] The bottom layer 302 of the fluid-filled chamber 300 is spaced apart from the top layer 301 to form a fluid-filled chamber 3 00. Like the upper layer 301, the lower layer 302 is may be formed from one or more polymeric materials, the same or different, in a thermoforming process.

In some examples, the top layer 301 and / or the bottom layer 302 may be In another example, the upper layer 301 and / or the lower layer 302 are heated before being placed therebetween. The mold may be heated to increase the temperature of the flow. In the molding process used to form the body fill chamber 300, the mold section Incorporating vacuum ports into the mold allows the top layer 301 and bottom layer 302 to be molded into their respective molds. In another embodiment, the upper layer 301 and the lower layer 302 are drawn into contact with each other to remove air. A fluid such as air is injected into the area between the top layer 301 and the bottom layer 302 to increase the pressure. and bottom layer 302 engages the surfaces of the respective mold parts.

[0047] The thickness of the fluid-filled chamber 300 is greater in the heel region 16 than in the forefoot region 12. In some examples, the thickness of the fluid-filled chamber 300 may vary from the heel region 16 to the forefoot. It gradually decreases through region 12, first occurring in heel region 16 where outsole 210 makes contact with the ground. Absorbs larger magnitude ground reaction forces that decrease as the ball rolls due to engagement of the ball. This provides a greater degree of cushioning for the

The regions facilitate flexion of footwear 10 as outsole 210 rolls for engagement with the ground. FIG. 5 illustrates a cross-sectional view of the lateral side 18 and the medial side 20. 1. Not shown is the portion of web region 308 that extends continuously.

[0056] In some embodiments, the grip may be designed to be flexible under an applied load, particularly during forward running motion of footwear 10. By attenuating the round repulsive force, the segments 311 to 324 have cushioning properties. Fluid-filled segments 3 when compressed or expanded to provide stability and support The segments 311-324 are fluidly coupled to each other to direct the fluid through the segments 311-324. 300 to form a unified pressure system for the fluid-filled chamber 300. Segments 311-313 and 317-324 are fluid-filled segments disposed in the forefoot region 12. The distal end 5 of the segment 324 and the fluid-filled segment 317 disposed within the midfoot region 14 and may cooperate to define a uniform serpentine shape for the fluid-filled chamber 300 extending between More specifically, the uniform serpentine shaped fluid-filled chamber 300 is aligned along the length of the sole structure 200.

In some examples, each The radius of the bends 3 is at least 3 mm. Furthermore, each bend 3 is Filler segments 311-324 are arranged around the sole structure 200 on the opposite side of the flange 306. The curved portion 3 is disposed on the opposite side of the flange 306 in the fluid-filled segment. This allows the fluid-filled segments to move freely during changes in direction between loads applied to the sole structure 200. The collapse of the segments 311 to 324 is prevented. One or more of these are fluidly isolated from the other segments 311-324, and at least one of segments 31 1-324 can be differentially pressurized.

Thus the fluid-filled segment 313 generally defines a horseshoe shape that fluidly couples to the fluid-filled segments 311 and 312 provided at one each of the inner side 20 and the outer side 18 respectively. In some examples, the fluid-filled segment 311 is longer than the length of the fluid-filled segment 3 12. For example, the fluid-filled segment 311 can extend longer from the heel region 16 towards the forefoot region 12 compared to the fluid-filled segment 312. In some examples, the fluid-filled segment 311 extends partially into the forefoot region 12. In some embodiments, the fluid-filled segment 314 extends between the fluid-filled segments 311, 3 12 and connects to the fluid-filled segments 311, 312. For example, the fluid-filled segment 31

[0059] 4 can extend in a direction substantially perpendicular from the outer side 18 to the inner side 20. Thus, the fluid-filled segment 314 fluidly connects to the fluid-filled segments 311, 312 and provides a fluid coupling between the fluid-filled segments 311, 312. The web region 30 8, i.e., the web region 308 formed such that the lower layer 302 adheres to the upper layer 301 ​​​​extends between and connects the fluid-filled segments 311-314 in the heel region 16. In this manner, the fluid-filled segments 311-314 may be formed in a web shape within the heel region 16. The web regions 308 cooperate to bind the upper 10 0 and mounted on the fluid-filled segments 311-314. 210. The mounting surface 212 of the mounting hole 210 is recessed relative to the ground surface 212 of the mounting hole 210.

Here, the plurality of fluid-filled segments 314-316 define a ladder configuration. The ribs 201 extend substantially parallel to each other in a direction substantially perpendicular to the longitudinal axis L of the rib structure 200. 3. Relieve torsional forces acting on the fluid-filled segments 311, 312, 313 during use of the This provides stability and support to the foot. In cooperation with the segments 311, 312, the spaced apart regions of the web region 308 may be provided. For example, the fluid filled segments 311-314 cooperate to form a first wall in the heel region 16. The fluid-filled segments 311, 312, 315, and 316 cooperate to constrain the web region 308. to constrain the second web region 308 within the midfoot region 14 and the fluid-filled segments 311, 3 12, 314, and 315 cooperate to define the area 3 between the first web area and the second web area. 3. The third web region 308 is constrained within the sole 308. The structure 200 is segmented between the outer side 18 and the inner side 20 to form a fluid-filled cell. 312, thereby providing torsional support to the outsole 21.
