本发明提供一种鞋底结构,具有复合弹性层以提供轻量化的效果。本发明的鞋底结构可运用于运动鞋、休闲鞋,但不限于此。请参考图1。图1为本发明鞋底结构10的一实施例仰视图。如图1所示,鞋底结构10包含低弹性层110。低弹性层110的本体110A具有第二面112及位于相反侧的第一面111(参见图2)。本体110A上形成有多个孔洞114贯穿第一面111及第二面112。The present invention provides a sole structure having a composite elastic layer to provide a lightweight effect. The sole structure of the present invention can be applied to sports shoes and casual shoes, but is not limited thereto. Please refer to Figure 1. 1 is a bottom plan view of an embodiment of a sole structure 10 of the present invention. As shown in FIG. 1, sole structure 10 includes a low elastic layer 110. The body 110A of the low elastic layer 110 has a second face 112 and a first face 111 on the opposite side (see FIG. 2). A plurality of holes 114 are formed in the body 110A to penetrate the first surface 111 and the second surface 112.
请配合图2。图2为对应图1的鞋底结构10的剖视图。如图2所示,鞋底结构10包含低弹性层110、中弹性层130以及高弹性层150。低弹性层110包含本体110A。本体110A包含相对的第一面111及第二面112。中弹性层130是设置于第一面111所在的一侧。如前所述,本体110A上形成有多个孔洞114贯穿第一面111及第二面112。高弹性层150填充于孔洞114中。Please cooperate with Figure 2. 2 is a cross-sectional view corresponding to the sole structure 10 of FIG. 1. As shown in FIG. 2, the sole structure 10 includes a low elastic layer 110, a middle elastic layer 130, and a high elastic layer 150. The low elastic layer 110 includes a body 110A. The body 110A includes opposing first and second faces 111, 112. The middle elastic layer 130 is disposed on a side where the first surface 111 is located. As described above, the body 110A is formed with a plurality of holes 114 extending through the first surface 111 and the second surface 112. The high elastic layer 150 is filled in the holes 114.
于一实施例,中弹性层130是设置于低弹性层110第一面111所形成的凹部116中。如图2所示,低弹性层110包含外侧壁110B。在鞋底结构10的外围是由外侧壁110B围绕本体110A并形成凹部116。中弹性层130设置于凹部116中并贴附于第一面111。从另一角度观之,凹部116为自外侧壁110B顶端118朝第一面111退缩所形成的空间,凹部116的底面作为第一面111。In one embodiment, the middle elastic layer 130 is disposed in the recess 116 formed by the first surface 111 of the low elastic layer 110. As shown in FIG. 2, the low elastic layer 110 includes an outer sidewall 110B. At the periphery of the sole structure 10, the body 110A is surrounded by the outer side wall 110B and a recess 116 is formed. The middle elastic layer 130 is disposed in the recess 116 and attached to the first surface 111. Viewed from another angle, the recess 116 is a space formed by retracting from the top end 118 of the outer sidewall 110B toward the first surface 111, and the bottom surface of the recess 116 serves as the first surface 111.
上述低弹性层、中弹性层、高弹性层意指使用具有不同弹性的材料。高弹性层或中弹性层表示相对于低弹性层具有更高的回弹性,在表面施力释放后较低弹性层更能恢复为原有形状。举例而言,高弹性层可为热塑性聚酯弹性体(Thermoplastic Polyester Elastomer,TPEE),其具有重量轻及耐疲劳的特 点。中弹性层可为直立棉,其具有更轻的重量,且提供舒适与透气的效果。低弹性层可为聚氨酯(Polyurethane,PU),其具有耐疲劳特性。由此,鞋体整体重量可大幅减轻,并维持耐用性。此外,采用具透气效果的直立棉可提高穿着的舒适感。由于直立棉为环保材质,因此采用直立棉的鞋底结构还可减低环境的负担。The above low elastic layer, medium elastic layer, and high elastic layer means that materials having different elasticity are used. The high elastic layer or the medium elastic layer means higher resilience relative to the lower elastic layer, and the lower elastic layer can be restored to the original shape after the surface is applied with force. For example, the high elastic layer may be a Thermoplastic Polyester Elastomer (TPEE) which has the characteristics of light weight and fatigue resistance. The medium elastic layer can be upright cotton, which has a lighter weight and provides a comfortable and breathable effect. The low elastic layer may be a polyurethane (PU) which has fatigue resistance. Thereby, the overall weight of the shoe body can be greatly reduced and durability can be maintained. In addition, the use of breathable upright cotton improves the comfort of wearing. Since the upright cotton is environmentally friendly, the sole structure of the upright cotton can also reduce the environmental burden.
图3为制作鞋底结构的流程图。如图3所示,鞋底结构的制作包含步骤S10:设置中弹性层。S20:灌注低弹性层。S30:低弹性层固化。S40:设置高弹性层。Figure 3 is a flow chart for making a sole structure. As shown in Figure 3, the fabrication of the sole structure includes a step S10 of setting the intermediate elastic layer. S20: perfusion of a low elastic layer. S30: The low elastic layer is cured. S40: Set a high elastic layer.
图4为制作鞋底结构10的俯视图。如图3及图4所示,鞋底结构10可利用模具20成型。模具20包含外围部分22及内部的凸柱24。外围部分22是用以形成鞋底结构10的轮廓。如图4所示,模具20内预先铺设中弹性层130。中弹性层130具有多个对应凸柱24的开口132,通过凸柱24和中弹性层130开口132用以形成前述孔洞。4 is a top plan view of the sole structure 10. As shown in Figures 3 and 4, the sole structure 10 can be formed using a mold 20. The mold 20 includes a peripheral portion 22 and an internal stud 24. The peripheral portion 22 is the contour used to form the sole structure 10. As shown in FIG. 4, the intermediate elastic layer 130 is preliminarily laid in the mold 20. The middle elastic layer 130 has a plurality of openings 132 corresponding to the protrusions 24, and the openings 132 are formed through the protrusions 24 and the middle elastic layer 130 to form the aforementioned holes.
图5及图6为分布低弹性层的示意图。如图3及图5所示,中弹性层130外表面131露出于模具20外。此外,中弹性层130以顶针190支撑,使中弹性层130底面135与模具20之间留有一高度差H1。低弹性层自中弹性层130外侧(即接近模具20外围部分22)箭号标示处灌注,以形成低弹性层。5 and 6 are schematic views of a distributed low elastic layer. As shown in FIGS. 3 and 5, the outer surface 131 of the middle elastic layer 130 is exposed outside the mold 20. Further, the middle elastic layer 130 is supported by the ejector pin 190 such that a height difference H1 is left between the bottom surface 135 of the middle elastic layer 130 and the mold 20. The low elastic layer is poured from the outside of the middle elastic layer 130 (i.e., near the peripheral portion 22 of the mold 20) at the arrow mark to form a low elastic layer.
如图6的局部放大图所示,模具20外围部分22与中弹性层130之间的空间与中弹性层130下方受支撑的空间连通,作为灌注的流道。低弹性层自中弹性层130外侧流经中弹性层130下方受支撑的空间而分布于整个模具20中。于一实施例,灌注的低弹性层可为液态PU,但不限于此。As shown in a partially enlarged view of Fig. 6, the space between the peripheral portion 22 of the mold 20 and the intermediate elastic layer 130 communicates with the supported space below the middle elastic layer 130 as a perfusion flow path. The low elastic layer is distributed from the outer side of the middle elastic layer 130 through the space supported by the middle elastic layer 130 to be distributed throughout the mold 20. In one embodiment, the infused low elastic layer can be a liquid PU, but is not limited thereto.
此外,部分低弹性层会沿着模具20的凸柱24向上流动。如图6所示,低弹性层流入凸柱24与中弹性层130之间的空间,并稍微往侧向挤压中弹性层130。挤压中弹性层130的过程中,低弹性层110自两者接触处渗入中弹性层130,形成结合。由此,低弹性层110除了连接中弹性层130的底面135(即位于顶针的一侧)以及中弹性层130接近外围部分22的一侧(例如侧面 133a)之外,在中弹性层130预留形成孔洞的一侧(例如侧面133b)亦与低弹性层连接,亦即于侧面133a、底面135与侧面133b皆有低弹性层110渗入中弹性层130,形成结合。如此一来,可提高不同弹性层之间的结合强度,避免不同弹性层分离。In addition, a portion of the low elastic layer will flow upward along the studs 24 of the mold 20. As shown in FIG. 6, the low elastic layer flows into the space between the stud 24 and the middle elastic layer 130, and slightly presses the middle elastic layer 130 laterally. During the extrusion of the intermediate elastic layer 130, the low elastic layer 110 penetrates into the middle elastic layer 130 from the contact between the two to form a bond. Thus, the low elastic layer 110 is pre-treated in the middle elastic layer 130 except for the bottom surface 135 of the middle elastic layer 130 (ie, the side on the thimble) and the side of the middle elastic layer 130 close to the peripheral portion 22 (for example, the side surface 133a). The side on which the hole is formed (for example, the side surface 133b) is also connected to the low elastic layer, that is, the side surface 133a, the bottom surface 135 and the side surface 133b have a low elastic layer 110 which penetrates into the middle elastic layer 130 to form a joint. In this way, the bonding strength between different elastic layers can be improved, and the separation of different elastic layers can be avoided.
图7及图8为设置高弹性层150的示意图。如图3及图7所示,待低弹性层110固化成型后脱模,原先中弹性层130下方由顶针所支撑的空间被填满而形成本体110A,包含第一面111及第二面112。原先中弹性层130与模具外围部分之间的空间被填满而形成外侧壁110B。外侧壁110B围绕本体110A以形成凹部116。第一面111上对应原先模具凸柱的位置则形成孔洞114。如图3及图7所示,中弹性层130具有相反于第一面111的外表面131,且具有多个对应孔洞114的开口132。此外,低弹性层110具有多个内环壁115立于第一面111上并围绕形成孔洞114,亦即,前述低弹性层110流入凸柱24与中弹性层130之间的部分(参考图6),沿着凸柱24周围固化后形成内环壁115。如图7的实施例所示,内环壁115夹于中弹性层130及高弹性层150之间。于一实施例,内环壁115自第一面111突出的高度H2与凹部116自外侧壁110B顶端118退缩的距离大致相等。7 and 8 are schematic views of the provision of the high elastic layer 150. As shown in FIG. 3 and FIG. 7 , after the low elastic layer 110 is solidified and molded, the space is removed, and the space supported by the thimble under the original middle elastic layer 130 is filled to form the body 110A, and includes the first surface 111 and the second surface 112. . The space between the original middle elastic layer 130 and the peripheral portion of the mold is filled to form the outer side wall 110B. The outer sidewall 110B surrounds the body 110A to form a recess 116. A hole 114 is formed in the first surface 111 corresponding to the position of the original mold stud. As shown in FIGS. 3 and 7, the middle elastic layer 130 has an outer surface 131 opposite to the first surface 111 and has a plurality of openings 132 corresponding to the holes 114. In addition, the low elastic layer 110 has a plurality of inner ring walls 115 standing on the first surface 111 and surrounding the holes 114, that is, the aforementioned low elastic layer 110 flows into the portion between the studs 24 and the middle elastic layer 130 (refer to the figure). 6), the inner ring wall 115 is formed after solidification along the periphery of the stud 24. As shown in the embodiment of FIG. 7, the inner ring wall 115 is sandwiched between the middle elastic layer 130 and the high elastic layer 150. In one embodiment, the height H2 of the inner ring wall 115 from the first face 111 is substantially equal to the distance at which the recess 116 is retracted from the top end 118 of the outer sidewall 110B.
接着如图3、图7及图8所示,将高弹性层150填充于孔洞114中。在此实施例,孔洞114自第一面111与第二面112之间的范围沿着内环壁115延伸至中弹性层130外表面131的一侧。在其他实施例,孔洞114的自第一面111朝外表面131的延伸范围可视高弹性层150的尺寸而调整。Next, as shown in FIGS. 3, 7, and 8, the high elastic layer 150 is filled in the holes 114. In this embodiment, the extent of the hole 114 from the first face 111 to the second face 112 extends along the inner ring wall 115 to one side of the outer surface 131 of the middle elastic layer 130. In other embodiments, the extent of the aperture 114 from the first face 111 toward the outer surface 131 can be adjusted depending on the size of the high elastic layer 150.
如图8所示,高弹性层150填充结束后,即完成鞋底结构10。以TPEE作为高弹性层150的例子中,可采用物理发泡方式制作TPEE。具体而言,制备高压液态的二氧化碳后进行减压并导入熔融态的TPEE中。减压后所形成高速气态二氧化碳使得TPEE涨大。最后进行冷却以制成TPEE。由此可以较环保的方式制成所需材料。As shown in FIG. 8, after the filling of the high elastic layer 150 is completed, the sole structure 10 is completed. In the case where TPEE is used as the high elastic layer 150, TPEE can be produced by physical foaming. Specifically, high-pressure liquid carbon dioxide is prepared, and then reduced in pressure and introduced into a molten TPEE. The high-speed gaseous carbon dioxide formed after decompression makes the TPEE increase. Finally, cooling is performed to make TPEE. This makes it possible to produce the required materials in a more environmentally friendly manner.
图9为本发明鞋底结构10的另一实施例仰视图。图10为对应图9的鞋底结构10的剖视图。如图9及图10所示,在足中段的位置(对应图9中两 虚线之间的范围)形成贯穿中弹性层130的低弹性层110,亦即,低弹性层110自第二面112贯穿中弹性层130而延伸至中弹性层130外表面131。由此可进一步使足中段周围的中弹性层130的侧面(例如侧面133c)与低弹性层110结合,亦即于侧面133c处有低弹性层110渗入中弹性层130而形成结合。如此一来,可提高整体强度及提供良好的耐曲折效果。Figure 9 is a bottom plan view of another embodiment of the sole structure 10 of the present invention. Figure 10 is a cross-sectional view of the sole structure 10 corresponding to Figure 9. As shown in FIGS. 9 and 10, the low elastic layer 110 penetrating the middle elastic layer 130 is formed at the position of the middle portion of the foot (corresponding to the range between the two broken lines in FIG. 9), that is, the low elastic layer 110 is from the second surface 112. The inner elastic layer 130 extends to the outer surface 131 of the middle elastic layer 130. Thereby, the side surface (for example, the side surface 133c) of the middle elastic layer 130 around the midfoot portion can be further combined with the low elastic layer 110, that is, the low elastic layer 110 is infiltrated into the middle elastic layer 130 at the side surface 133c to form a joint. In this way, the overall strength can be improved and a good tortuosity effect can be provided.
图11为本发明鞋底结构10的另一实施例剖视图。于低弹性层110、中弹性层130以及高弹性层150制作完成后,可包含贴合覆盖层的步骤。如图11所示,鞋底结构10更包含覆盖层160。覆盖层160贴合外表面131且遮蔽凹部。于一实施例,覆盖层160可采用与低弹性层110相同的材料,但不限于此。此外,鞋底结构10还包含大底层180。大底层180设置于第二面112。通过设计,可利用覆盖层160作为足底侧的踩踏面,提供较平均的踩踏效果。Figure 11 is a cross-sectional view of another embodiment of the sole structure 10 of the present invention. After the low elastic layer 110, the middle elastic layer 130, and the high elastic layer 150 are completed, the step of bonding the cover layer may be included. As shown in FIG. 11, the sole structure 10 further includes a cover layer 160. The cover layer 160 conforms to the outer surface 131 and shields the recess. In an embodiment, the cover layer 160 may be the same material as the low elastic layer 110, but is not limited thereto. In addition, sole structure 10 also includes a large bottom layer 180. The large bottom layer 180 is disposed on the second side 112. By design, the cover layer 160 can be utilized as a tread surface on the sole side to provide a more average pedaling effect.
图12为本发明鞋底结构10的另一实施例剖视图。如图12所示,与前一实施例的差异在于,覆盖层160作为大底层。例如,采用PU作为覆盖层。此外,鞋底结构10还包含碳纤维片170。碳纤维片170设置于第二面112。通过设计,配合碳纤维片170并直接以覆盖层160作为大底层,可使整体重量较轻。Figure 12 is a cross-sectional view of another embodiment of the sole structure 10 of the present invention. As shown in FIG. 12, the difference from the previous embodiment is that the cover layer 160 serves as a large bottom layer. For example, a PU is used as an overlay. In addition, the sole structure 10 further includes a carbon fiber sheet 170. The carbon fiber sheet 170 is disposed on the second surface 112. By designing, the carbon fiber sheet 170 is combined and the cover layer 160 is directly used as the large bottom layer, so that the overall weight is light.
本发明已由上述相关实施例加以描述,然而上述实施例仅为实施本发明的范例。必需指出的是,已公开的实施例并未限制本发明的范围。相反地,包含于权利要求的精神及范围的修改及均等设置均包含于本发明的范围内。The present invention has been described by the above related embodiments, but the above embodiments are merely examples for implementing the present invention. It must be noted that the disclosed embodiments do not limit the scope of the invention. Rather, modifications and equivalent arrangements are intended to be included within the scope of the invention.
