可應用於大體上被認為是非運動鞋的鞋，如淑女鞋、休閒 鞋、涼鞋及工作勒：。因此，熟悉此技藝人士應瞭解到此處 揭露的概念除了下文中及圖中揭露的特定式樣之外，可運 用在各種鞋類。 10第一室 [52] 第1圖中所示的一鞋10包括一鞋幫20及一鞋底結構 體30。鞋幫20大體上為習知構形，且包括數個元件，如織 布、泡沫及皮革材料，其縫或黏接在一起，以形成用以穩 固且舒適地容納腳的一内部空間。鞋底結構體30定位在鞋 15幫20下，且包括兩個主要元件，一中底31以及一外底32。 中底31以譬如縫或黏接方式固定至鞋幫2〇之一表面，且其 在鞋底結構體30撞擊地面時可減弱力量及吸收能量。亦 即，中底31可在走路或跑步時使腳具有襯墊的效果。外底 32固定至中底31的一下表面，且以適於接合地面的一耐 20用、耐磨材料形成。此外，鞋底結構體30可包括一内底， 其為一薄的襯墊元件，定位在空間内，且毗鄰腳的足底表 面，以強化鞋10的舒適度。 [53] 中底31主要以聚合泡沫材料製成，如聚胺基甲酸酯 或乙烯醋酸乙烯酯，其包封住—以流體填充之室4〇。如第2 13 1286468 及3圖所示，室40定位在中底31的一腳跟區中，其在腳落地 時與最高的起動重力區對應。然而室4〇可定位在中底31的 任何區中，以獲得一所欲程度的襯墊程度。此外，中底Μ 可包括具有室40之一般構形的數個以流體填充室。 5 [54]室40在圖中具有一囊的結構體，其中聚合材料密封 層包封住流體。可選擇地，室4〇可形成在中底31内的間隙。 亦即，具有室40形狀的材料可不出現在中底31中，以形成 室40。 [55] 與習知室比較，室40及其在中底31的泡沫材料中的 10配置可在最初的壓縮階段為一既定的重力產生相當大的偏 斜。然而’當室40的壓縮力增加時，室4〇的堅硬度亦相對 地增加。對於壓縮力的此種回應係由於室4〇的結構，以及 室40加入中底31中的方法，以下將詳細說明。一般而言， 室40的結構體具有一單一室，以流體填充囊的特徵，尤其 15 是，室40具有以五個葉狀部42a-42e圍繞的一中間區41，該 葉狀部分別具有一遠端43a-43e，如第4-7圖中所示。葉狀 部42a-42e自中間區41向外徑向地延伸。因此，葉狀部 42a-42e可自中間區41的週邊以不同的方向向外延伸。中底 31以及填充葉狀部42a-42e之間的空間之中底31的泡沫材 20料在腳跟下的特定區上備置空氣與泡沫的適合比例。 [56] 為便於參考，在第6A及7圖中出現的一縱轴44通過中 間區41及葉狀部42c而延伸。室40針對通過縱轴44而延伸， 且大體上與第6A、7圖中的平面垂直的一平面是對稱的，其 餘部份則是不對稱的。因此，室4〇的結構體大體上類似於 12^6468 一棕樹樹葉的形狀。室40亦包括一第一表面45、一相對的 第二表面46、以及在第一表面45及第二表面46之間延伸的 一側壁47。第一表面45及第二表面46具有一大體上平面的 構形，且相互平均地間隔。第一表面45與第二表面46的形 5狀大體上相同，但其面積較小，因此，側壁47在個別葉狀 部42a-42e之間的區上彎曲。譬如，侧壁47的坡度可大約為 田比鄰中間區41 40度’此鄰遠端43a-43e大約為80度，且在其 間的區上由40度逐漸改變成80度。然而，在遠端43心436的 位置下，侧壁47大約具有90度的垂直坡度。側壁47可大體 10上具有平面的構形，其相對於第一表面45形成一角，或側 壁47可·彎曲。 [57] 中底31的特定構形以及室40的方位可在本發明範圍 内改變。譬如，當以中底31的聚合泡沫材料包封住之後， 遠端43a-43e的一部份可延伸至中底31的一邊緣33，且可通 15過邊緣33而延伸，使得它們可由鞋10的外部看得到。此外， 第一表面45可與中底31的上表面之平面共同延伸，使得腳 跟接合第一表面45。可選擇地，室4〇可完全嵌在中底31的 泡沫材料内，或可定位成使第二表面46與中底31的上表面 之平面為共同延伸的平面。然而，如第卜3圖所示，遠端 20 43a—43e不通過邊緣33延伸，而第二表面46定位成田比鄰中底 31的一下表面。此構形使得中底31的泡沫材料之一部份置 於腳及第一表面45之間。 [58] 側壁47的坡道，如第6B-6D之橫截面圖中所示，繞著 室40而改變’以在壓縮時自室40至中底31的聚合泡沫材料 15 1286468 10 壓2稍同的壓力下。因此，在室40中的流體壓力可在每平 ^央忖G至超過5销壓力範圍内。由於在室40中相當低的 堅力’用以形成第-表Φ45、第二表面46及侧壁47的材料 不須備置可操作以維持習知示之相當高流體壓力的障壁特 徵。因此’ 一大範圍的聚合材料，如熱塑性氨基甲酸乙酯 可用來形成第一表面45、第二表面46及侧壁47，且相當多 的流體’如空氣’可用於室4G中。此外，相當大範圍的聚 合材料可依據材料之卫程特性而選擇，如動態係數及耗損 係數’而非材料之阻止室40所容納之流體的驅散之能力。 當以熱塑性聚氨基甲酸乙酯形成時，第一表面45、第二表 面46及侧壁47的厚度大約為〇〇4〇英吋，但其厚度可在譬如 0.018英吋至〇·〇6〇英对之間。 [61]在室40中的流體之相當低的壓力亦使室40及習知室 不同。在習知室中相當高的壓力常需要在聚合層之間形成 15内部的連接部，以阻止室向外擴張至一顯著的程度。亦即， 内部連接部用於習知室中，以控制室的整體厚度。相反地， 室40的第一表面45及第二表面46之間無内部的連接部。 [62]室40可以數種製造技術製造，包括吹模、熱成形、 以及轉動模造等。有關於吹模技術，熱塑性材料置於具有 2〇 大體上室40之形狀的一模中，而加壓空氣用來誘導材料塗 敷模的表面。在熱成形技術中，熱塑性材料層置於一模的 對應部份之間，且模用來在室4〇的週邊位置壓縮層在一 起。一正麼可施加在熱塑性材料層之間’以誘導層進入模 的輪廓中。此外，真空可引入層之間的區中，且模拉動層 17 1286468 至模的輪廓中。 [63] 室40及其在中底31的泡沫材料中的配置與在本發明 之背景中所述的以流體填充之室比較，在壓縮的最初階段 可在一既定重力下產生一相當大的偏斜。然而，當室40的 5 壓縮增加時，室40的堅硬度由於室40之結構體以及室40加 入中底31的方法而以對應方式增加。三種現象同時操作， 以產生上述效果，且包括壓力變化，中底31的泡沫材料以 及薄膜張力。此三種現象將在下文中說明。 [64] 壓力變化為室40壓縮而產生的結果。實際上，室40 10 在中底31中未壓縮時具有一最初壓力，以及最初的體積。 然而，當中底31壓縮時，室40的有效體積增加，因而增加 室40中的流體壓力。壓力的增加可提供中底31之一部份緩 衝回應。 [65] 泡沫材料的特性亦影響中底31的緩衝回應，且將在 15 下文中就泡沫材料之構形及厚度加以說明。有關於構形， 中底31中的泡珠材料可在Asker C scale中具有50-90的硬 度，且其，譬如，集中在邮t鄰邊緣33處，且在對應於室40 之中間的區中較少。葉狀部42a-42e的數量可改變。以，譬 如，減少中底31的週邊部份上空氣與泡沫的比例，中底31 20 的此種改變可用來增加中底31在壓縮時的整體硬度。因 此，泡沫材料的形狀及室40的對應形狀對於緩衝回應具有 影響力。 [66] 最後，薄膜的張力對於緩衝回應具有影響力。此回 應與加壓的習知室比較即可明瞭。在習知室中，室内的壓 18 1286468 習知室壓縮時，外層上的 室的壓縮操作，以減輕外 ’在第一表面45上的張力 力使得外層在張力下，然而，當 張力鬆開，或減少。因此，習知 層上的張力。與加壓習知室比較 由於第一表面45的彎曲，0庵厭w 口應壓縮而增加。此張力的增加 造成上述的緩衝回應。在宫4n 仕至40轉動，使得第二表面46定位 成毗鄰腳的應用中，第-矣 禾一表面46上的張力回應壓縮而增 加，以促成緩衝回應。 [67] 壓力I化，錄材料的特性以及薄膜張力共同減弱 力量及吸收能量。壓力變化，泡沐材料的特性以及薄膜張 1〇力對於緩衝回應的影響依據相對於室40的位置而改變。在 對應於遠端43a-43e之位置的室4〇之週邊部份上泡珠材料 的特性提供減少的柔順性，因而增加了對應的堅硬度。由 於位置企圖朝向中間區4卜長柱34逐漸尖細，且允許相當 大的偏斜，且減弱力量且吸收能量的主要現象為薄膜張力 15及壓力變化。熟悉此技藝人士依據以上所述可瞭解到鞋底 結構體30的特定緩衝回應主要與上述的室4〇之一般構形及 中底31的泡沫材料有關。 [68] 依據壓力變化、泡沫材料之特性及薄膜張力的考 量，中底31的緩衝回應可改良，以備置所欲程度的力量減 20弱及能量吸收。譬如，室40之體積，葉狀部42a-42e之數量 及形狀，側壁47之坡度，第一表面45、第二表面46之厚度， 用以形成室40之外部的材料以及室40在中底31中的位置及 方向可改變，以改良緩衝回應。此外，泡珠材料之特性， 包括硬度及厚度，亦可調整以改良緩衝回應。因此藉由改 19 12^6468 二=^他參數，中底31可為各別顧客的量身訂作，以 在壓縮時僙置特定的緩衝回應。 第二室 5 10 15 20 [69]本發明的另一實施例為第8圖中的鞋10，。鞋1〇，包括 一鞋幫20’及一鞋底結構體3〇,。鞋幫2〇，大體上具有習知構 形，其形成用以穩固地且舒適地容納腳的内部空間。鞋底 結構體30,定位在鞋㈣，下且包括兩個主要元件，一中底 31’及一外底32’。中底31，固定至鞋幫2〇,的一下表面，且可 在鞋底結構體30,接觸地面時減弱力量及吸收能量。外底犯， 固定至中底31’的-下表面，且以耐用、财磨的接觸地面之 材料形成。此外，鞋底結構體30,可包括-内底，其為一薄 的襯墊元件，且定位在空間内，並就鄰腳，以強化鞋10,的 舒適性。因此’鞋1G’大體上的結構體類似於上述的鞋10。 然而，鞋H)，的主要不同在於中底3ι，的結構體，尤其是嵌在 中底31’的泡沫材料内的一室4〇，之結構體。 [70] +底31’主要以聚合泡沐材料製成，如聚氨基甲酸乙 醋或聚醋酸乙烯S旨’且室4〇’定位在中底31，的一腳跟區内， 如第9、10圖中所示。室4〇,如第1M5圖所示，包括一中門 區41，，七個葉狀部42，，，，以及七個對應的遠端區 心’’’。此外，室4〇,包括用作參考目的是-軸44,、一第 一表面45,、-第二表面46，以及_側壁47，。室4()，對稱地繞 著通過軸44,延伸的_平面’且大體上與第—表㈣二 表面46的平面垂直，其他部份為不對稱的。㈣的第 面45及第二表面46场上具有平面的構形，室40,的第一表 20 1286468 '、有脅曲的構形。亦即，毗鄰遠端43a，-43c，以及 43e-43g’的第一表面45,之部份向上料，以形成一圓的或 凹、口構體。相反地，在葉狀部，上的第一表面衫，之部份 大體上具有扁平的構形。 5 [71]參看第9、1〇圖，其中顯示在中底μ，中的室仙，之位 置 般而$，室40’定位成使得第二表面46,與在中底31， 中的泡朱材料的一下表面共同延伸。此構形置放中底31，中 之泡珠材料的一部份於腳及第一表面45,之間。遠端 43a -43c及43e’-43g’亦與中底31，的一邊緣33,共同延伸。因 1〇此，遠端43a，-43c，及ue，-4#，可自鞋1〇，的外部看得到。由 於第二表面46,的彎曲構形，葉狀部42aM2c，和42eM2g，在 其自中間區41，至遠端43a，-43c，及43e，-43g，向外放射時高 度及體積均增加。體積的增加允許流體在壓縮時自中間區

Description of the invention: [Technical field to which the invention pertains; field of the invention [4] (4) A fluid-filled chamber, particularly a type of hideable shoe, wherein the chamber has a 1-shaped structure. [Prior Art] Conventional Background Art [2] A conventional shoe includes two main components, an upper, and a sole structure. Take sneakers as an example, the upper 10 15 20 swimming and leather, the number of things ^ Γ _, such as weaving, foaming and comfortable accommodation - chat to form - space in the interior of the shoe and - outsole - The multi-structure has an inner bottom including a midsole to strengthen the inner bottom of the shoe, and an adjacent-intermediate layer, and a thinner element. The bottom of the towel forms a bottom structure or a polyacetate. Made of eucalyptus material, such as polyurethane, urethane, durable, wear-resistant = mid-bottom-lower surface, and ready to be attached = shrinking:: = 3 material forming the midsole - applying gravity under the elastic bubble The elasticity of the bead material/, and the energy absorbed by the walking or running butterfly, is determined by the fact that the inner space is partially reduced by the gas displacement material including the structural body. That is, the bubble structure body can be a bag that seals the air. However, after the 4th compression, the drop was small. Therefore, I: permanently collapses, thus causing the compression force of the foam [〇4] 1 = ^ the vibration force will drop. The method of the fluid-filled chamber disclosed in U.S. Patent No. 4,183,156, the entire disclosure of which is incorporated herein by reference. data. The fluid-filled chamber has a bladder structure comprising an outer enveloping member formed of an elastomeric material defining a plurality of tubular members extending longitudinally over the length of the shoe. 5 The tube elements are in fluid communication with one another and collectively extend across the width of the shoe. A similar fluid-filled chamber encased in a blister material is disclosed in U.S. Patent No. 4,219, 094, the entire disclosure of which is incorporated herein by reference. [05] U.S. Patent No. 4,8,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,, When the midsole is compressed, the chamber expands into the aperture. Therefore, the aperture is provided with reduced stiffness when the midsole is compressed, while reducing the overall weight of the shoe. In addition, by properly positioning the aperture in the foam material, the overall response to shock can be adjusted over a particular area of the shoe. [06] The fluid filled chamber described above can be fabricated in a dual film technique in which two separate elastomeric film layers are formed to have the complete shape of the chamber. The layers are then fused together along their respective perimeters to form an upper surface, a lower surface, and a side wall of the chamber, and the layers are welded together at predetermined internal locations to provide the chamber with a desired configuration. The shape, that is, the inner portions of the layers are interconnected to form a predetermined shape and size at the desired location. Next, the chamber is pressurized to atmospheric pressure by inserting a nozzle or needle connected to a fluid pressure source into a fill port in the chamber. After the chamber is pressurized, the nozzle is removed and the inlet port is filled to seal, for example, in a welded manner. 1286468 [〇7] Another technique for making a fluid filled chamber of the above type is the blow molding method wherein the fluidized elastomeric material is placed in a mold having the overall desired shape and configuration of the chamber. The mold has an opening through which pressurized air is placed. The pressurized air forces the fluidized elastomeric material against the inner surface of the mold and causes the material to harden in the mold to form a chamber having the desired configuration. [08] Another type of apparatus for the midsole of the shoe is disclosed in U.S. Patent Nos. 4,906,502 and 5,083, the entire disclosures of each of which are incorporated herein by reference. The chamber includes a sealed outer barrier layer that is firmly joined to the double walled fabric core. The core has 10 layers of upper and lower outer fabrics separated from each other by a predetermined distance, and can be manufactured by a double needle bar Raschel knitting method. The joining yarn of the multi-fiber yarn having a plurality of individual fibers may be internally extended & fixed to the fabric layer between the facing surfaces of the fabric layer. The individual fibers of the joined yarn form a tension limiting element that limits the barrier layer from moving outwardly a desired distance.

The advantage of this design is that the edges are seamless on the largest sidewall bend zone and the visibility of the interior of the interior including the joined yarns is increased. The method for making such a chamber includes forming a housing including a lower surface and a side wall in a mold. A double wall fabric core is placed on top of a cover layer, and after the mold is removed, the casing is placed on the cover layer and the core. The combined housing, cover and core are then moved to a stacking station where the radio frequency can be placed to align the opposite sides of the core to the housing and cover and to weld the perimeter of the housing to the cover. The chamber is then pressurized by the insertion fluid to place the connecting yarn 1286468 under tension.

[11] The material of the above chamber forms an outer layer which can be formed of a polymeric material, such as a thermoplastic elastomer which is not substantially permeable to the fluid in the middle. In particular, a suitable material is a thin layer formed by alternating layers of a thermoplastic polyurethane and an ethylene vinyl alcohol copolymer, such as U.S. Patents 5,713, 141 1 and 5, 叩 2 of Mitchell et al.

SUMMARY OF THE INVENTION [13] The present invention is a chamber for a shoe comprising a first surface, an opposite 15 second surface, and a side wall extending between the edges of the first and second surfaces. The side wall engages the first surface and the second surface such that no internal connection secures the inner portion of the first surface to the inner portion of the second surface. The fluid is sealed indoors at atmospheric pressure and a pressure of 5 pounds per square inch of atmospheric pressure. In addition, a plurality of leaves extend outwardly from an intermediate portion of the chamber. The 20-lobed portion is defined by a first surface, a second surface, and a side wall, and the leaf portion is in fluid communication with the intermediate portion. [14] The first and second surfaces may have a planar configuration. Alternatively, one of the surfaces may be curved. In addition, the portion of the sidewall defined between the lobes may have a sloped configuration, and the portion of the sidewall adjacent the distal end of the lobate may have a substantially vertical slope. [15] - The lobes extend radially outward from the intermediate zone. Therefore, the leaves can extend outward from the periphery of the intermediate portion in different directions. The number of lobes can vary within the scope of the present invention. The lobes are located in the work space of the five adjacent leaves of the field. After being incorporated into the shoe, the chamber is at least partially encapsulated within a polymeric bead material such that the polymeric material extends between the leaves to form a struts-like and σ-supporting surface that contacts the sidewalls and has Adjacent to the shape of the space between the leaves. Thus, the struts have a slope configuration corresponding to the slope of the side walls.

[Embodiment] DETAILED DESCRIPTION OF THE INVENTION Introduction 12 1286468 [51] The following description and drawings disclose a sports shoe incorporating a fluid-filled bladder according to the present invention. The concept associated with shoes, particularly fluid filled bladders, is revealed by having suitable shoes for running. However, the present invention is not limited to running shoes, and can be applied to various sports shoes, including basketball shoes, off-road shoes, 5 walking shoes, tennis shoes 'soccer shoes, mountaineering, and the like. Further, the present invention is also applicable to shoes which are generally considered to be non-sports shoes, such as ladies shoes, casual shoes, sandals, and work clothes. Accordingly, those skilled in the art will appreciate that the concepts disclosed herein can be applied to a variety of footwear in addition to the specific features disclosed herein and in the drawings. 10 First Chamber [52] A shoe 10 shown in Figure 1 includes an upper 20 and a sole structure 30. The upper 20 is generally of a conventional configuration and includes a plurality of components, such as woven, foam, and leather materials that are sewn or bonded together to form an interior space for securely and comfortably receiving the foot. The sole structure 30 is positioned under the shoe 15 and includes two main components, a midsole 31 and an outsole 32. The midsole 31 is fixed to one surface of the upper 2 by, for example, seaming or bonding, and it weakens the force and absorbs energy when the sole structure 30 hits the ground. That is, the midsole 31 can provide a cushioning effect on the foot when walking or running. The outsole 32 is secured to the lower surface of the midsole 31 and is formed of a durable, wear resistant material suitable for engaging the ground. In addition, the sole structure 30 can include an insole that is a thin cushioning member positioned within the space adjacent the sole surface of the foot to enhance the comfort of the shoe 10. [53] The midsole 31 is primarily made of a polymeric foam material, such as polyurethane or ethylene vinyl acetate, which is enclosed by a fluid-filled chamber. As shown in Figures 2 13 1286468 and 3, the chamber 40 is positioned in a heel region of the midsole 31 which corresponds to the highest starting gravity zone when the foot is lowered. However, the chamber 4 can be positioned in any zone of the midsole 31 to achieve a desired level of padding. Additionally, the midsole can include a plurality of fluid-filled chambers having the general configuration of chamber 40. 5 [54] The chamber 40 has a bladder structure in the figure wherein the polymeric material sealing layer encapsulates the fluid. Alternatively, the chamber 4A may form a gap in the midsole 31. That is, a material having the shape of the chamber 40 may not be present in the midsole 31 to form the chamber 40. [55] Compared to the conventional room, the chamber 40 and its 10 configuration in the foam of the midsole 31 can produce a substantial deflection for a given weight during the initial compression phase. However, when the compressive force of the chamber 40 is increased, the hardness of the chamber 4 is relatively increased. This response to the compressive force is due to the structure of the chamber 4 and the method by which the chamber 40 is added to the midsole 31, as will be described in more detail below. In general, the structure of chamber 40 has a single chamber that fluidly fills the features of the bladder, and in particular, chamber 40 has an intermediate portion 41 surrounded by five lobes 42a-42e, each having A distal end 43a-43e, as shown in Figures 4-7. The lobes 42a-42e extend radially outward from the intermediate portion 41. Therefore, the leaves 42a-42e may extend outward in different directions from the periphery of the intermediate portion 41. The foam material 20 of the midsole 31 and the space intermediate portion 31 between the fillet portions 42a-42e is provided with a suitable ratio of air to foam on a specific area under the heel. For ease of reference, a longitudinal axis 44 appearing in Figures 6A and 7 extends through the intermediate region 41 and the lobes 42c. The chamber 40 is symmetrical about a plane extending through the longitudinal axis 44 and substantially perpendicular to the plane in Figures 6A, 7 with the remainder being asymmetrical. Therefore, the structure of the chamber 4〇 is substantially similar to the shape of 12^6468 a palm tree leaf. The chamber 40 also includes a first surface 45, an opposing second surface 46, and a sidewall 47 extending between the first surface 45 and the second surface 46. The first surface 45 and the second surface 46 have a generally planar configuration and are evenly spaced from one another. The first surface 45 is substantially identical to the shape of the second surface 46, but has a smaller area so that the side wall 47 is curved over the area between the individual leaf portions 42a-42e. For example, the slope of the side wall 47 may be approximately 40 degrees Celsius in the intermediate zone 41. The adjacent distal ends 43a-43e are approximately 80 degrees, and the zone therebetween is gradually changed from 40 degrees to 80 degrees. However, at the position of the center 43 of the distal end 43, the side wall 47 has a vertical slope of approximately 90 degrees. The side wall 47 can have a generally planar configuration thereon that forms an angle with respect to the first surface 45, or the side wall 47 can be curved. The particular configuration of the midsole 31 and the orientation of the chamber 40 can vary within the scope of the invention. For example, after encapsulation with the polymeric foam of the midsole 31, a portion of the distal ends 43a-43e can extend to an edge 33 of the midsole 31 and can extend 15 through the edge 33 such that they can be worn by the shoe The outside of 10 can be seen. Additionally, the first surface 45 can coextend with the plane of the upper surface of the midsole 31 such that the heel engages the first surface 45. Alternatively, the chamber 4 can be fully embedded within the foam of the midsole 31 or can be positioned such that the plane of the second surface 46 and the upper surface of the midsole 31 are coextensive planes. However, as shown in Fig. 3, the distal ends 20 43a-43e do not extend through the edge 33, while the second surface 46 is positioned to the lower surface of the midsole 31. This configuration causes one of the foams of the midsole 31 to be placed between the foot and the first surface 45. [58] The ramp of the side wall 47, as shown in the cross-sectional view of Figures 6B-6D, is changed around the chamber 40 to slightly compress the polymeric foam material 15 1286468 10 from the chamber 40 to the midsole 31 during compression. Under the pressure. Thus, the fluid pressure in chamber 40 can range from a level of G to more than 5 pin pressures. Because of the relatively low strength in chamber 40, the materials used to form the first gauge Φ45, the second surface 46, and the side walls 47 need not be provided with barrier features that are operable to maintain the relatively high fluid pressures conventionally shown. Thus, a wide range of polymeric materials, such as thermoplastic urethane, can be used to form first surface 45, second surface 46, and side walls 47, and a significant amount of fluid, such as air, can be used in chamber 4G. In addition, a relatively wide range of polymeric materials can be selected based on the process characteristics of the material, such as the dynamic coefficient and the loss factor' rather than the ability of the material to prevent the fluid contained in the chamber 40 from dissipating. When formed of thermoplastic polyurethane, the first surface 45, the second surface 46, and the side walls 47 have a thickness of about 4 inches, but the thickness can be, for example, from 0.018 inches to 〇·〇6〇. Between the English and the British. The relatively low pressure of the fluid in chamber 40 also causes chamber 40 and the conventional chamber to be different. The relatively high pressures in conventional chambers often require the formation of internal connections 15 between the polymeric layers to prevent the chamber from expanding outward to a significant extent. That is, the internal connection is used in the conventional room to control the overall thickness of the chamber. Conversely, there is no internal connection between the first surface 45 and the second surface 46 of the chamber 40. [62] The chamber 40 can be manufactured in a variety of manufacturing techniques, including blow molding, thermoforming, and rotational molding. With respect to the blow molding technique, the thermoplastic material is placed in a mold having a shape of 2 大体上 substantially the chamber 40, and pressurized air is used to induce the surface of the material coating mold. In the thermoforming technique, a layer of thermoplastic material is placed between corresponding portions of a mold, and the mold is used to compress the layers together at the peripheral locations of the chambers 4''. A positive can be applied between the layers of thermoplastic material to induce the layer into the contour of the mold. In addition, a vacuum can be introduced into the region between the layers, and the mold pulls the layer 17 1286468 into the contour of the mold. The arrangement of the chamber 40 and its foam in the midsole 31 is comparable to that of a fluid-filled chamber as described in the context of the present invention, which produces a substantial amount at a given gravity during the initial stages of compression. Skewed. However, as the 5 compression of the chamber 40 increases, the stiffness of the chamber 40 increases in a corresponding manner due to the structure of the chamber 40 and the method by which the chamber 40 is added to the midsole 31. The three phenomena operate simultaneously to produce the above effects, and include pressure changes, foam of the midsole 31, and film tension. These three phenomena will be explained below. [64] Pressure changes are the result of chamber 40 compression. In effect, chamber 40 10 has an initial pressure, as well as an initial volume, when uncompressed in midsole 31. However, as the midsole 31 compresses, the effective volume of the chamber 40 increases, thereby increasing the fluid pressure in the chamber 40. An increase in pressure provides a partial response to the midsole 31. [65] The properties of the foam also affect the cushioning response of the midsole 31 and will be described below in relation to the configuration and thickness of the foam. Regarding the configuration, the bead material in the midsole 31 may have a hardness of 50-90 in the Asker C scale, and it, for example, concentrates on the adjacent edge 33 of the post, and in the middle of the area corresponding to the chamber 40 Less in the middle. The number of leaves 42a-42e can vary. For example, to reduce the ratio of air to foam on the peripheral portion of the midsole 31, such a change in the midsole 31 20 can be used to increase the overall stiffness of the midsole 31 when compressed. Therefore, the shape of the foam and the corresponding shape of the chamber 40 have an impact on the cushioning response. [66] Finally, the tension of the film has an influence on the buffer response. This response can be compared to a pressurized conventional room. In the conventional room, the internal pressure 18 1286468 is compressed during the compression of the chamber, the compression operation of the chamber on the outer layer to relieve the external tension on the first surface 45 so that the outer layer is under tension, however, when the tension is loosened , or reduce. Therefore, the tension on the layer is known. Compared with the pressurization chamber, due to the curvature of the first surface 45, the 0 庵 w w should be compressed and increased. This increase in tension causes the above buffer response. In the application of the rotation of the vestibule 4 to 40 such that the second surface 46 is positioned adjacent to the foot, the tension on the surface 46 of the first ridge is increased in response to compression to promote a cushioning response. [67] Pressure I, the characteristics of the recorded material and the film tension together weaken the force and absorb energy. The pressure changes, the characteristics of the foam material, and the effect of the film tension on the cushioning response vary depending on the position of the chamber 40. The characteristics of the bead material on the peripheral portion of the chamber 4's at the locations corresponding to the distal ends 43a-43e provide reduced compliance, thereby increasing the corresponding stiffness. Since the positional attempt is tapered towards the intermediate zone 4, the long column 34 is allowed to be deflected, and the main phenomenon of weakening the force and absorbing energy is the film tension 15 and the pressure change. It will be appreciated by those skilled in the art from the foregoing that the particular cushioning response of the sole structure 30 is primarily related to the general configuration of the chamber 4 and the foam of the midsole 31 described above. [68] Depending on pressure changes, characteristics of the foam and film tension, the buffer response of the midsole 31 can be improved to provide the desired level of strength minus 20 and energy absorption. For example, the volume of chamber 40, the number and shape of leaf portions 42a-42e, the slope of side wall 47, the thickness of first surface 45, second surface 46, the material used to form the exterior of chamber 40, and chamber 40 at the midsole The position and orientation in 31 can be changed to improve the buffer response. In addition, the properties of the bead material, including hardness and thickness, can also be adjusted to improve buffer response. Therefore, by changing the parameters of the 19 12^6468 2=^, the midsole 31 can be tailored for each customer to set a specific buffer response during compression. Second Chamber 5 10 15 20 [69] Another embodiment of the present invention is the shoe 10 of Figure 8. The shoe 1〇 includes an upper 20' and a sole structure 3〇. The upper 2 is generally of a conventional configuration that forms an interior space for securely and comfortably receiving the foot. The sole structure 30, positioned under the shoe (four), includes two main components, a midsole 31' and an outsole 32'. The midsole 31 is fixed to the lower surface of the upper 2, and can weaken the force and absorb energy when the sole structure 30 contacts the ground. The outsole is fixed to the lower surface of the midsole 31' and is formed from a durable, rich material that touches the ground. In addition, the sole structure 30 can include an insole that is a thin cushioning member that is positioned within the space and adjacent to the foot to enhance the comfort of the shoe 10. Thus the general structure of the 'shoe 1G' is similar to the shoe 10 described above. However, the main difference of the shoe H) lies in the structure of the midsole 3, especially the structure of a chamber embedded in the foam of the midsole 31'. [70] + bottom 31' is mainly made of a polymeric foam material, such as polyurethane or polyvinyl acetate S, and the chamber 4〇 is positioned in the heel region of the midsole 31, as in the ninth. Figure 10 shows. The chamber 4, as shown in Fig. 1M5, includes a middle door region 41, seven leaf portions 42, and, and seven corresponding distal center portions ''. Further, the chamber 4, including for reference purposes, is a shaft 44, a first surface 45, a second surface 46, and a side wall 47. Chamber 4(), symmetrically about the axis 44 extending through the axis 44, is substantially perpendicular to the plane of the surface of the first (four) surface 46, and the other portions are asymmetrical. The fourth surface 45 and the second surface 46 of (4) have a planar configuration, and the first table 20 1286468' of the chamber 40 has a textured configuration. That is, portions of the first surface 45 adjacent the distal ends 43a, -43c, and 43e-43g' are upwardly directed to form a round or concave, mouthed body. Conversely, the portion of the first top garment on the lobes has a generally flat configuration. 5 [71] See Figure 9, Figure 1, which shows the position in the midsole μ, in the position of $, the chamber 40' is positioned such that the second surface 46, with the bubble in the midsole 31, The surface of Zhu material is extended together. This configuration places the midsole 31 with a portion of the bead material in between the foot and the first surface 45. The distal ends 43a-43c and 43e'-43g' also coextend with an edge 33 of the midsole 31. Because of this, the distal ends 43a, -43c, and ue, -4# can be seen from the outside of the shoe. Due to the curved configuration of the second surface 46, the leaves 42aM2c, and 42eM2g, both from the intermediate portion 41 to the distal ends 43a, -43c, and 43e, -43g, increase in height and volume as they are radiated outward. The increase in volume allows the fluid to increase from the intermediate zone 41' to the distal ends 43a'-43c' and 43e'-43g' upon compression, thereby gradually transitioning from a fairly compliant 15 buffer response to a hard buffer response. Moreover, the increase in volume at the distal ends 43a'-43c' and 43e'-43g' reduces the pressure of the overall fluid within the chamber 40' under a given degree of compression. The slope of the side wall 47', as shown in the cross-sectional view of Figures 13B-13D, is varied around the chamber 40' to provide a smooth transition during compression. The side walls 47 are curved between the leaf portions 20a'-42g' and generally have a vertical slope at the distal ends 43a, -43e. The space between the lobes 42a'-43g' is generally U-shaped, which is formed by a curved surface of the side wall 47', and the portion of the side wall 47 that is positioned between the leaf portions 42a'-42g' has The slope is larger in the zone adjacent to the distal end 43a, ~43g, in the zone than in the zone adjacent to the intermediate zone 41'. In particular, the side wall 47 has a relatively narrow slope corresponding to one of the U-shaped circular portions at the intermediate portion 41 of the adjacent portion 21 1286468. When the side wall 47 extends between the intermediate portion 41 and the distal ends 43a-43e, the slope increases. However, at the distal ends 43a-43e, the ramp of the side wall 47 is generally vertical. 10 15 20 [73] The basic movements of the foot during running are as follows: First, the heel hits the ground and the foot is taken. When the heel leaves the ground, the foot rolls forward, bringing the toe into contact with the ground, and finally the entire foot leaves the ground to begin another cycle. When the foot is in contact with the ground and rolls forward, it also rolls from the outside or side to the inner or middle side. This is called internal rotation. When the foot is in the air and is ready for another cycle, there is an opposite action called extraversion. At the time of running, the intermediate portion 41 has a larger compliance force than the corresponding portion of the leaf portions 42a - 42e to cause the chamber to move, thereby counteracting the rolling of the foot toward the intermediate side. In other implementations, the size of the leaves 42a-42e and the characteristics and number of foams can be varied to limit the internal rotation action. A similar concept can also be applied in the chamber. 4] Same as chamber 40, chamber 40, and its midsole 31, which is matched with the fluid-filled chamber described in the background of the invention, at the initial stage of compression, at -岐A considerable deflection occurs under gravity. However, when the compression of the pair of helium is increased, the rigidity of the chamber 4G is increased by the structure of the midsole 31. This effect is also a result of pressure changes, medium and fine, medium beading, enthalpy and film tension. Therefore, the volume of the chamber 40, the number and shape of the leaves and the =a to 42g, the slope of the side wall 47, the thickness of the surface valence of the first surface portion midsole 31, are used to form the outer material of the chamber 4G. And in addition, the location and orientation of the room* can be changed to improve the buffer response. Characteristics of the foam material, including the amount of foam, hardness and thick sound 22 1286468 [78] The above blow molding method utilizes a mold having two corresponding mold portions. Each of the mold portions has a substantially planar surface, and a recess in the surface, and the shape of the recess corresponds to one of the shapes of the chamber, and therefore, the closed mold portion is formed in a cavity in the crucible, and the cavity has a chamber shape. 5 Because the shape of the structure of the conventional mold must be stretched, it can extend into the groove, and the extension will reduce the entire thickness of the type of bad wall. To offset the effect of stretching, the shape is generally extensible to the desired level. The initial wall thickness of the thin wall thickness. This effect of the offset extension is suitable in the case where the structure of the mold allows the mold to be stretched in a substantially uniform manner. However, if the structure of the mold is such that the proportion of the blown portion of the type 10 bad stretch is larger than that of the other portions, it is not suitable to increase only the bad wall thickness, because the wall of the chamber is uneven. thickness. [80] Conventional recesses having a flat surface and a groove forming the shape of the chamber generally cause the specific portion of the type to be stretched to a greater extent than the other portions. For example, in the formation of the distal end 43a, -43g, and the first surface 45, the chamber 4, the chamber 40, the type of the portion of the chamber is generally extended to form a bad portion of the intermediate portion 41. The degree of stretching is large. Therefore, the thickness of the chamber 4'' at the junction of the distal end 43a, -43g, and the first surface 45 is substantially smaller than the thickness of the upper chamber 40' in the intermediate portion 41. However, the following blow molding method of the chamber 40 can form the first surface 45 having a uniform thickness, the second surface 46, and the side walls 47. Another result of the conventional mold structure is that a dividing line is formed in the middle of a side wall of the chamber. As described above, the opposite sides of the die compression type are joined together and form a joint between the opposite sides. The joint represents the dividing line and corresponds to the area where the opposing mold portions meet. In some shoe applications, the side walls of the chamber are visible to 24 1286468. Therefore, positioning a dividing line in the middle of the side wall detracts from the aesthetics of the chamber. However, in the blow molding method of the chamber 4, the dividing line is positioned at the middle of the non-side wall 47, and particularly not corresponding to the distal end 43a, - 43g. 5 [82] A mold 100 that can be used to form chamber 40 is shown in Figures 16-18. The mold 100 includes a first mold portion 110 and a corresponding second mold portion 120. When joined together, the cavities formed by the mold portions 110 and 120 are substantially the same size as the outer diameter of the chamber. Unlike the conventional blow molding method for forming a shoe chamber, the mold portion and the 120 have no planar surface adjacent to the cavity forming the chamber 40. Conversely, the first dies define a plurality of notches 111a-c and llle-g, and the second dies 12 界定 define a plurality of projections 121a-c and 121e-g, as shown in Fig. 16. The first mold portion 110 is shown in Fig. 17, and forms a portion of the chamber 4A corresponding to the first surface 45' and the region of the side wall 47 adjacent to the intermediate portion 41. The first mold portion 110 also forms a region with the distal end 43d, corresponding to the side wall 47. The ridge 112 extends around a middle portion of the first mold portion 110. As will be described below, the ridges 112 may partially form a dividing line on the chamber 4'. Accordingly, the first surface 牝, and the portion of the side wall 47', are formed in the region of the first mold portion 110 surrounded by the ridge 112. In particular, the surface of the first mold portion 110 that is generally positioned adjacent an intermediate portion 113 forms an intermediate portion 41, and a surface that is generally positioned about the plurality of leaf portions 20 regions U4a-IHg is formed on the first surface 45, Portions of the upper leaf portions 42a'-42g' and generally positioned about the side wall regions 115a-U5g form portions of the side walls 47 that are adjacent to the intermediate portion 41. [84] The front surface 45 of the distal ends 43a, -43c, and 43e, -43g, the portion 45 is bent upward to form a circular or concave structure, such as in the chamber 4, said 25 I286468 As stated in the Ming Dynasty. To form this configuration, the region of the first mold portion 110 positioned within the region surrounded by the ridges 112 has a corresponding convex configuration. Thus, the surface of the first mold portion 110 has a curved configuration from the intermediate portion 113 to the side wall regions 114a-c and 114e-g.

As described below, the recess 116 is used to form a conduit through which fluid can be directed into the chamber 40'. Another feature of the first mold portion 110 is a plurality of venting holes 117 distributed through the intermediate portion 113 and the side wall regions 114a-114g. During the manufacturing chamber 40', when the mold is pulled into the first mold portion 110, the venting holes 117 are provided with outlet holes for the air. [86] The second mold portion 120 is shown in Fig. 18 and forms a portion of the chamber 40' corresponding to the second surface 46', and a side corresponding to the distal ends 43a, -43c, and 43e, -43g, Wall 47, zone. A ridge 122 extends around an intermediate portion of the second mold portion 120 and forms a dividing line on the chamber 40 with the ridge 112. Therefore, when the 15th mold portion 110 is coupled to the second mold portion 120, the ridge 112 is positioned in close proximity to the ridge 122. The region of the second mold portion 120 positioned within the region surrounded by the ridge 122 forms a second surface 46' and a region of the side wall 47 corresponding to the distal ends 43a, -43c, and 43e, -43g. In particular, the surface of the second mold portion 12(), which is generally positioned adjacent to an intermediate portion 123, forms an intermediate portion 41 formed substantially at the surface that is positioned around the plurality of leaf portions 2〇l24a-12 The two surfaces 46, the portions of the upper leaf portions 42a - 42g', and the surfaces generally positioned around the distal regions 125a-c and 125e-g correspond to the distal ends 43a, -43c, and 43e, -43g, Side wall 47, part of it. [87] As for the chamber 40'' second surface 46' has a generally planar configuration. The region of the first mold portion 12 that corresponds to the intermediate portion 123 and the leaf portion regions 124a-124g and that forms the second surface 26 1286468 46 also has a generally planar configuration. The distal regions 125a-c and 125e-g extend upwardly from the leaflet regions 124a-c and 124e-g, respectively, to provide a substantially planar region defining the distal ends 43a, -43c, and 43e, -43g. An extension of the ridge 122 extends outwardly from the lobed region 124 (1) and defines an L-shaped groove 126. The recess 116 is configured to form a conduit through which fluid can be injected into the chamber. The mold portion 120 also includes a plurality of venting holes 127 which are distributed through the intermediate portion 123 and the leaf portion regions I24a-124g. Like the venting holes 117, during the manufacturing process of the chamber 40', the type is broken. When the second mold portion 12 is in the middle, the vent hole 127 is provided with an air outlet hole. 1〇[88] the recesses llla-c and llle-g, and the protruding portions 121a-c and 121e-g are formed from the mold portion of the forming chamber 40'. The portions 110 and 120 extend outwardly. In particular, the notches 111a-c and llle-g extend radially outward from the leaf portions 114&-c and U4e-g, respectively. Similarly, the projections 12la- c and 121e-g extend radially outward from the leaflet regions 124a-c and 124e-g, respectively, so that the notches Ula-c and 15llle-g and the projections 121a-c and 12le-g substantially Partial alignment of the dies 1a forming the lobes 42a'-42c' and 42e-42g' is shown in the following. [89] A method of forming the chamber 4〇 with a type of bad 13 使用 using the mold 100 will be described below. Generally hollow The polymeric material is melted. The tubular shape herein is not limited to a cylindrical shape having a circular cross section, and includes a configuration having an elongated or elliptical cross section. When the shaped defect 130 is formed, the molten polymeric material is squeezed from a mold. The wall thickness of the type 130 is substantially fixed or can be changed around the periphery of the type 13 (). Therefore, the cross section of the type 13 can exhibit different wall thickness regions. The material includes the above-mentioned materials in the manufacturing chamber 4〇 and the chamber 4〇. 27 1286468 [90] After the 13th shape is formed as described above, the type i3〇 is suspended between the mold portions 110 and 120, as shown in Fig. 19. As shown in the discussion, the mold has a first side 131 facing the first mold portion 110, and the mold 13 has a second side 132 facing the second mold portion 120. Then, the mold The sections 11〇 and 12〇 are aligned, and 5 makes the concave nma-recognition 1116-discrimination correspond to the protrusions 12ia-c and i2ie-boo. At this position, the chambers 11〇, the molds 11〇 and 12〇 are positioned. On the opposite sides of the die 130, and also aligned. Then, the dies 11 and 12 位移 are displaced toward each other, so that the die 100 is in contact with the bad 13 As shown in Fig. 2, in particular, the surface 10 of the first mold portion 11 where the recesses 111a-c and llle-g are formed contacts the first side 131, and the projections 121a-C are formed. The surface of the second mold portion 120 of I21e-g contacts the second side edge 132. [91] When the mold 1〇〇 contact type is broken 130, the portion of the mold defect 130 is bent to match the mold portions 110 and 120 toward each other. Move further, as shown in Figure 2. In particular, the first side edge 131 is bent into the recesses iiia-c and iHe-g, 15 and the second side edge 132 is bent around the projections 121a-c and 121e-g. Therefore, the mold 13 continues to bend as the mold portions 110 and 120 continue to move toward each other. [92] When the mold portions 110 and 120 are further moved toward each other, the projections 121a-c and 121e-g extend entirely into the recesses 11a-c and iiie-g, while the side 131 of the defective 130 leans against the type The side 132 of the bad 130 is compressed to engage a portion of the side 20 side 131 to the side 132, as shown in FIG. However, an intermediate portion of the mold 130 contacts and cooperates with the surface of the mold 40 to be formed. Accordingly, an intermediate portion of the first side edge 131 contacts and conforms to the contours of the intermediate portion H3, the lobed regions 114a-114g, and the sidewall regions 115a-115g. Similarly, an intermediate region of the second side 132 contacts and conforms to the contours of the intermediate region 123, the leaf regions 28 1286468 124a-124g, and the distal regions 125a-c and 125e-g. In addition, the ridges 112 and 122 compress the sides 131 and 132 together to form a joint portion of the peripheral portion of the sealed chamber 40. [93] When the mold 1 is closed, a fluid having a positive pressure compared to atmospheric air, 5 such as air, is incident between the sides 131 and 132 to induce the contact 130 to match the contours of the molds 110 and 120. . Initially, fluid is delivered from the molding mechanism forming the bad 130 and guided along the longitudinal direction of the profile 130 to prevent the sides 131 and 132 from contacting each other. However, when the die 1 is closed on the die 13 , the fluid can be directed through the conduit formed by the grooves 116 and 126. For example, a needle 10 can pass through the mold 130 at the inlet of the conduit and transport fluid along the conduit to the region of the forming chamber 40'. Air may also be removed from the area between the die 13 and the mold portions 110 and 120 through the vents 117 and 127 to pull the type 13 to the surfaces of the mold portions 110 and 120. [94] Once the chamber 40' is formed in the mold 1〇〇, the mold portions 11 and 12 are separated, 15 so that the mold can be removed from the first mold portion 110, as shown in Figs. The mold 130 is then allowed to cool, and the conduit formed by the grooves 116 and 126 can be sealed to enclose the fluid within the chamber 4 at atmospheric pressure. Alternatively, the excess of the defective 130 can be cut or removed from the chamber. The excess can be recycled to form other types of damage. 2 [95] According to the above, the mold portions 110 and 120 each substantially include a curved shape and form a formation region having a different function. The curved region includes notches ii〇a-c and nie_g with respect to the first mold portion 11A. Therefore, the bending zone contributes to the engagement front bending type 130. The formation zone includes an intermediate zone 113, leaflet zones 114a-114g, and sidewall zones 115a-115g. Thus, the formation zone helps to extend horizontally between the wall 29' and the first surface 45' of the 29 1286468. Then, the dividing line 133 extends vertically across the side wall 47' and along the sides of the distal ends 43a'-43c, and 43e, -43g. Therefore, at least a portion of the dividing line 133 extends between the first surface 45 and the second surface 46'. The dividing line 133 also extends horizontally between the side walls 47' and the second surface 46' in the region between the leaves 42g'-42g. As shown in Fig. 8, after being incorporated into the shoe, the dividing line 133 is substantially viewable and the dividing line 133 does not span the distal ends 43a, -43g of the visible portion of the chamber 40'. Therefore, the dividing line 133 is not in the middle of the side wall 47. The non-linear dividing line 133 causes a specific area of the side wall 47 to be formed by the first side 10131 or the first side 132. For example, the side wall 47 of the middle zone 41, hereinafter referred to as the first zone, is formed by the first side 131. Thus, the first region of the side wall 47 extends from the first surface 45 to the second surface 46 and is formed by the first side 131. Similarly, the side walls 47 of the distal ends 43a, -43c, and 43e, -4 are referred to as the second regions, and are formed by the second side edges 132. Thus, the second region of side 15 wall 47' also extends from first surface 45 to second surface buckle and is formed by second side edge 132. In general, the first and second zones are alternated such that the first side and the first side are joined to form a side wall. [99] The above-described blow molding method is different from the conventional blow molding method for manufacturing a shoe room. For example, the mold (10) includes a plurality of concave nllla-c and llle-g, and a plurality of 20 dog out-phase la-c and 121e, g, so that the material is bad before joining or stretching, so that the wall of the chamber 40 has The thickness of the sentence. In addition, the curvature of the profile 130 is formed so as not to straddle the sidewall 47, such as a non-central separation line 133 extending from the visible portion of the crucible.
