Description

具有弹性支撑片的高弹性鞋中底及高跟鞋 技术领域
本发明涉及一种鞋中底，尤其涉及一种使穿着者的穿着更舒适的高弹性鞋 中底及具有该高弹性鞋中底的高跟鞋。 背景技术
随着经济的不断发展，为人们提供了极其丰富的物质条件，从而提高了人 们的生活水平，正由于人们生活水平的不断提高，使得人们对产品的要求越来 越高， 而质好、 轻便及时尚的产品总是受到消费者的青睐。
其中， 在制鞋行业中， 由于高跟鞋能提升女性的整个身体的骨架， 同时还 使女性的整个身体挺拔起来， 从而令到女性穿着者更有自信， 且姿态更优雅， 从而为高跟鞋发展提供一个良好的平台。
高跟鞋包括鞋面、鞋底及鞋跟这三大部分， 而鞋底包含有与鞋面连接的大 底及设置于大底上的鞋中底， 其中， 鞋中底的厚度在高跟鞋中有严格的要求， 同时， 鞋中底还必须要满足支撑穿着者体重的强度要求， 因此， 鞋中底在满足 支撑强度的条件下做得越薄越好，且鞋中底根据其承载脚底的部位不同包括脚 跟部和脚掌部，脚跟部与人体的脚后跟相匹配对应，脚掌部与人体的脚掌相匹 配对应； 具体到高跟鞋，脚跟部与高跟鞋的鞋跟对应， 脚掌部与高跟鞋的着地 部对应，人体的重量分别通过鞋跟和着地部这两个部位被支撑，从而能平稳穿 着高跟鞋行走。
如图 1所示， 现有的鞋中底 200包括有与穿着者的脚底接触的上硬质层 210、 粘于上硬质层 210底面的中硬质层 220、 粘于中硬质层 220底面的下硬 质层 230及嵌设于中硬质层 220中的细长的铁条 240, 使得由铁条 240、 上硬 质层 210、中硬质层 220及下硬质层 230形成的鞋中底 200又硬且不具有弹性， 故在穿着者的脚底支撑于该鞋中底 200上时，其没法自动地调整与穿着者的脚 底的接触部位， 以增加两者之间接触面积，从而使得穿着者的脚底在单位面积 内受到的压强更大；又由于与穿着者的脚底接触的硬质底层 210没法对穿着者 的脚底进行柔性的緩冲作用，故使得现有的鞋中底 200的穿着舒适性极差而没 法满足穿着者对穿着舒适性的要求； 再者， 由铁条 240、 上硬质层 210、 中硬 质层 220及下硬质层 230形成的鞋中底 200存在结构复杂及太笨重的缺陷 ,进 一地使得现有的鞋中底 200没法满足穿着者对穿着舒适性的要求。 同时，为了 避免人体直接踩在铁条 240上的不适感，上硬质层 210及下硬质层 230—般选 用容易加工但是也有较高硬度的材料制作，长时间踩在较硬的包裹材料上会感 到脚掌疼痛。且铁条 240非常坚硬但是没有弹性， 刚性太大的铁条 240给脚弓 很大的反作用力， 穿着时间久了以后会导致脚弓 S史痛并致使脚踝受损。
对于任何款式的高跟鞋，优美的外观造型十分重要，这就必须限制高跟鞋 结构层中底的厚度，才可以保证附着了其它附件后的鞋子还能轻巧和精致。原 有结构的中底因为厚度和材料性能所限，满足了支撑安全后很难再满足穿着舒 适的要求。所以在现有的技术下，往往都是通过在高跟鞋内底上增设鞋垫来提 高舒适度，但是由于鞋子内腔空间狭窄， 鞋垫的厚度都极其有限， 太薄的鞋垫 无法发挥出应有的作用 ,致使原有中底的高跟鞋其实艮难通过增设鞋垫来提高 舒适度。 在保证高跟鞋优美造型和穿着支撑安全的情况下，如何提高高跟鞋的 舒适度是个急需解决的问题。
同样， 在除高跟鞋以外的鞋子的鞋中底中， 也存在着类似的问题。
因此，急需要一种能满足穿着者对穿着舒适性要求且结构简单的高弹性鞋 中底及具有该高弹性鞋中底的高跟鞋来克服上述的缺陷。
发明内容
本发明的一目的在于提供一种能满足穿着者对穿着舒适性要求且结构简 单的具有弹性支撑片的高弹性鞋中底。
本发明的另一目的在于提供一种能满足穿着者对穿着舒适性要求且结构 简单的高跟鞋。
为实现上述的目的， 本发明提供一种具有弹性支撑片的高弹性鞋中底， 设置于鞋内上并对穿着者的脚底进行支撑，其中，本发明具有弹性支撑片的高 弹性鞋中底包括软质面层及呈弹性片状结构的弹性支撑片，软质面层贴附于弹 性支撑片上，弹性支撑片的长度自软质面层的脚跟部至少延伸至软质面层的脚 掌部， 弹性支撑片的宽度与脚底的宽度相匹配。
较佳地， 弹性支撑片的宽度延伸至对应的大底与鞋面的连接叠合处。 较佳地， 软质面层和弹性支撑片成一体结构。
较佳地， 弹性支撑片为金属片。
较佳地，弹性支撑片的前端与水平地面平行，弹性支撑片的后端朝远离水 平地面方向向上倾斜，且弹性支撑片的前端与弹性支撑片的后端之间连接有弧 形过渡的弯曲结构。
较佳地， 弹性支撑片上具有若干加强筋。
较佳地， 加强筋沿弹性支撑片的后端至前端方向设置。
较佳地，弹性支撑片的前端设置有镂空结构，弹性支撑片的后端设置有供 与鞋跟固定连接用的安装孔。
本发明的高跟鞋包括大底、鞋面、鞋跟及前述的具有弹性支撑片的高弹性 鞋中底。
较佳地， 弹性支撑片的宽度延伸至对应的大底与鞋面的连接叠合处。 撑片上， 弹性支撑片的长度自软质面层的脚跟部至少延伸至软质面层的脚掌 部，且弹性支撑片的宽度与脚底的宽度相匹配，故在本发明具有弹性支撑片的 高弹性鞋中底支撑不同体重的穿着者时,使弹性支撑片带动软质面层产生与穿 着者的脚底相对应的弹性形变，从而使得本发明具有弹性支撑片的高弹性鞋中 底能根据穿着者的不同体重自动的调整该高弹性鞋中底与穿着者的脚底的接 触部位， 以增加两者之间的接触面积，使得穿着者的脚底在单位面积内受到的 压强极小，再结合软质面层对脚底起柔性緩冲的作用，进而使得本发明具有弹 性支撑片的高弹性鞋中底在满足支撑强度的条件下具有更轻的重量及更好的 穿着舒适性而满足穿着者对舒适性的要求；又由于本发明具有弹性支撑片的高 弹性鞋中底仅由软质面层及弹性支撑片构成，故使本发明具有弹性支撑片的高 弹性鞋中底的结构得到简化。 同理， 由于本发明具有弹性支撑片的高弹性鞋中 底， 故本发明的高跟鞋同样能更好地满足穿着者对舒适性的要求。 附图说明

为了详细说明本发明的技术内容、构造特征， 以下结合实施方式并配合附 图作进一步说明。
请参阅图 2及图 3 ,本发明具有弹性支撑片的高弹性鞋中底 10设置一 鞋内并用于对穿着者的脚底进行支撑，其中，本发明具有弹性支撑片的高弹性 鞋中底 10包括软质面层 11及呈弹性片状结构的弹性支撑片 12, 软质面层 11 贴附于弹性支撑片 12上， 弹性支撑片 12的长度自软质面层 11的脚跟部 111 至少延伸至软质面层 11的脚掌部 112, 弹性支撑片 12的宽度与脚底的宽度相 匹配。 具体地， 在达到对穿着者的支撑强度的条件下， 弹性支撑片 12的宽度 可以大于或等于脚底的宽度， 或者略小于脚底宽度； 较优是， 弹性支撑片 12 的宽度延伸至如图 4中对应的大底 20与鞋面 30的连接叠合处，以使弹性支撑 片 12对穿着者进行可靠支撑的同时， 也为它产生的弹性形变提供所需要的空 间。 其中， 在本实施例中， 软质面层 11与脚底相匹配且与该脚底相接触， 为 脚底提供柔性的緩冲效果， 且软质面层 11较优为由发泡聚氨酯 （英文简称为 PU )、 发泡丙烯酸酯改性聚氨酯 （英文简称为 PUA )或发泡橡校形成的软质 面层 11 , 以降低成本并具有良好的柔性緩冲效果； 而弹性支撑片 12较优为金 属片，尤其为由弹簧钢形成的金属片以具有更优的弹性形变性能及更好的支撑 性能。 更具体地， 如下：
较优者， 软质面层 11和弹性支撑片 12成一体结构， 以使得软质面层 11 与弹性支撑片 12之间的结合更可靠及更牢固； 具体地，软质面层 11是通过注 塑成型工艺与弹性支撑片 12成一体结构，以简化由软质面层 11和弹性支撑片 12形成一体结构的工艺过程； 其中， 形成由软质面层 11和弹性支撑片 12组 成的一体结构的高弹性鞋中底 10方法是： 首先，提供一弹性支撑片 12;接着， 将弹性支撑片 12置于模具的成型腔中； 然后，往置有弹性支撑片 12的成型腔 内注塑有熔融的软质材料， 例如为发泡聚氨酯（英文简称为 PU )、 发泡丙烯 酸酯改性聚氨酯 （英文简称为 PUA )或发泡橡校等， 熔融的软质材料与弹性 支撑片 12相结合而在弹性支撑片 12上形成出软质面层 11 , 从而使软质面层 11与弹性支撑片 12共同形成一初品； 最后， 冷却初品， 使初品成型出由软质 面层 11和弹性支撑片 12组成的一体结构的高弹性鞋中底 10。 当然， 上述的 一体结构还可以由其它工艺所形成的，例如可以为压注成型或粘合工艺等。更 具体地，在本实施例中，一体结构中的软质面层 11贴附于弹性支撑片 12的顶 面上， 以使本发明具有弹性支撑片的高弹性鞋中底 10在规定的尺寸厚度内增 加与脚底相接触的软质面层 11的厚度，从而进一地提高软质面层 11对穿着者 的脚底柔性緩冲之效果； 当然， 在其它实施例中， 也可以使弹性支撑片 12内 嵌于软质面层 11内。 当弹性支撑片 12与软质面层 11不是做成一体结构时， 此时的软质面层 11较优地通过粘胶工艺使其贴附于弹性支撑片 12的顶面上， 也能进一地提高软质面层 11对穿着者的脚底柔性緩冲之效果。
同时，弹性支撑片 12的前端 12b与水平地面平行，弹性支撑片 12的后端 12a朝远离水平地面方向向上倾斜， 以提穿着者的整个身体的骨架， 同时还使 穿着者的整个身体挺拔起来； 且弹性支撑片 12的前端 12b与弹性支撑片 12 的后端 12a之间连接有弧形过渡的弯曲结构 12c, 以使本发明具有弹性支撑片 的高弹性鞋中底 10与穿着者的脚底的接触更佳而使本发明具有弹性支撑片的 高弹性鞋中底 10具有更优的穿着舒适性。
最后， 弹性支撑片 12上具有若干加强筋 121 , 以增加弹性支撑片 12的弹 性形变的效果及支撑强度； 具体是， 加强筋 121沿弹性支撑片 12的后端 12a 至前端 12b方向设置； 较优地， 加强筋 121是朝远离软质面层 11的方向向外 冲压形成的，使得软质面层 11可以部分嵌入弹性支撑片 12内以增加两者结合 的可靠性， 进一地提高弹性支撑片 12的弹性形变的效果； 更具体是， 弹性支 撑片 12的前端 12b设置有镂空结构 122, 镂空结构 122可以降低弹性支撑片 12的重量并能增加软质面层 11与弹性支撑片 12的结合接触处， 以提升软质 面层 11与弹性支撑片 12连接的可靠性； 且弹性支撑片 12的后端 12a设置有 供与图 4中的鞋跟 40固定连接用的安装孔 123 , 以使得弹性支撑片 12与鞋跟 40的连接更可靠，使鞋跟 40通过弹性支撑片 12能对穿着者进行可靠的支撑， 而加强筋 121较优地位于安装孔 123与镂空结构 122之间。
请参阅图 4, 图 4展示了本发明的高跟鞋的一个较优实施例。 在图 4中， 本发明具有弹性支撑片的高弹性鞋中底 10最佳是应用于高跟鞋 100中， 作为 本发明高跟鞋 100的组成部分， 以使得具有本发明高弹性鞋中底 10的高跟鞋 100具有更优的穿着舒适性， 当然， 除了本发明提及的高跟鞋 100外， 本发明 具有弹性支撑片的高弹性鞋中底 10还可以应用于其它类型的鞋上， 在此不对 本发明具有弹性支撑片的高弹性鞋中底 10的应用范围进行限制。 其中， 本发 明的高跟鞋 100包括大底 20、鞋面 30、鞋跟 40及本发明具有弹性支撑片的高 弹性鞋中底 10。 具体地， 在本实施例中， 鞋面 30是连接于大底 20上而形成 出供穿着者的脚穿着该高跟鞋 100用的穿着腔 50, 本发明具有弹性支撑片的 高弹性鞋中底 10设于穿着腔 50内， 鞋跟 40连接于本发明具有弹性支撑片的 高弹性鞋中底 10上， 且鞋跟 40与本发明高弹性鞋中底 10的脚跟部 111相对 应， 以使脚跟部 111被鞋跟 40所支撑。 更具体地， 在本实施例中， 鞋面 30 可以通过车缝工艺或粘胶工艺使鞋面 30连接于大底 20上，但不限于此； 而鞋 跟 40可通过外界金属连接件使弹性支撑片 12的后端 12a与鞋跟 40固定连接 在一起， 但不限于此。 较优地， 弹性支撑片 12 的宽度延伸至对应的大底 20 与鞋面 30的连接叠合处， 目的使弹性支撑片 12对穿着者达到更好的支撑，也 为它产生的弹性形变提供所需要的空间。
与现有技术相比， 由于本发明的软质面层 11贴附于呈弹性片状结构的弹 性支撑片 12上， 弹性支撑片 12的长度自软质面层 11的脚跟部 111至少延伸 至软质面层 11的脚掌部 112, 且弹性支撑片 12的宽度与脚底的宽度相匹配， 故在本发明具有弹性支撑片的高弹性鞋中底 10支撑不同体重的穿着者时， 使 弹性支撑片 12带着软质面层 11产生与穿着者的脚底相对应的弹性形变，从而 使得本发明具有弹性支撑片的高弹性鞋中底 10能根据穿着者的不同体重自动 的调整该高弹性鞋中底 10与穿着者的脚底的接触部位， 以增加两者之间的接 触面积， 使得穿着者的脚底在单位面积内受到的压强极小， 再结合软质面层 11 对脚底起柔性緩冲的作用， 进而使得本发明具有弹性支撑片的高弹性鞋中 底 10在满足支撑强度的条件下具有更轻的重量及更好的穿着舒适性而满足穿 着者对舒适性的要求； 又由于本发明具有弹性支撑片的高弹性鞋中底 10仅由 软质面层 11及弹性支撑片 12构成，故使本发明具有弹性支撑片的高弹性鞋中 底 10的结构得到简化。同理，由于本发明具有弹性支撑片的高弹性鞋中底 10, 故本发明的高跟鞋 100同样能更好地满足穿着者对舒适性的要求。
以上所揭露的仅为本发明的较佳实例而巳 当然不能以此来限定本发明之 权利范围， 因此依本发明权利要求所作的等同变化， 仍属于本发明所涵盖的范 围。
