Description

复合式自行车坐垫 技术领域
本发明涉及自行车的坐垫，特别是指一种使用二种以上材料组成的复合式自行车坐垫。
背景技术
目前市面上有许多各种各样不同型式与不同材料所制成的自行车坐垫，这些坐垫也各有其优点与缺点。早期的坐垫是以塑料射出制成再加上金属的轨道利用胶黏合而成。金属轨道有可能是珞钼钢或是铁材，但是因为塑料与金属的轨道二者的弹性系数差距较大，所以容易损坏而且重量重。后来为了减重将金属轨道改为碳纤维材料制成，虽然重量减少了但是一样是使用胶与坐垫黏合，所以容易有脱胶的风险。后来改以碳纤维来制造坐垫与轨道，再以碳纤维来接合二者，此种结构虽然可以将坐垫与轨道结合成一体但是制造成本过高，不符合经济效益不利于大量生产。
发明公开
本发明的主要目的在于提供一种可以提高坐垫本体与轨道结合稳定性及且有利于大量生产的复合式自行车坐垫。
为了达成上述主要目的，本发明的复合式自行车坐垫包含有：一坐垫本体，呈长三角形，前端较窄后端较宽，该坐垫本体是由一上外层、一下外层以及一中间层叠合所构成的一三明治结构，其中该上外层与下外层为相同材质，中间层为另一材质。一轨道，由二轨道支杆所组成，该轨道具有一前端与一后端，该二轨道支杆在前端处结合在一起然后朝后端分叉开，该轨道在前端处及二轨道支杆分叉的后端处各设有一贯孔，该轨道设置在该坐垫本体下外层的下方，并且该轨道的三贯孔分别对应连通该坐垫本体的三通孔。一前结合件以及二后结合件，该前结合件与该二后结合件各具有一外端部，该外端部的外径大于该轨道上贯孔的孔径及该坐垫本体通孔的孔径，各结合件外端部的一侧凸设有一结合部，该等结合件以其结合部插设在对应的轨道的贯孔以及该坐垫本体的通孔，并且以该结合部与该坐垫本体的上外层、下外层或中间层的一者融熔接合 成一体。
由上述结构可知，本发明的复合式自行车坐垫可以利用该等结合件与该坐垫本体上外层、下外层或中间层的一者材质相同而可融熔接合成一体的特性使该坐垫本体与该轨道可以通过该等结合件牢牢的结合在一起，以改善昔用产品的脱胶的问题。
有关本发明所提供的详细构造、特点、组装或使用方式，将于后续的实施方式详细说明中予以描述。然而，在本发明领域中具有通常知识者应能了解，该等详细说明以及实施本发明所列举的特定实施例，仅系用于说明本发明，并非用以限制本发明的专利申请范围。

一前结合件30以及二后结合件40，该前结合件30与该二后结合件40是采用与该坐垫本体中间层13相同材质所制成。该前结合件与该二后结合件各具有一外端部31，41，该等外端部的外径大于该轨道上贯孔22的孔径，也大于该坐垫本体任一通孔的孔径。各结合件外端部的一侧凸设有一柱状的结合部32，42。该前结合件30以其结合部32插设在该轨道前端的贯孔22以及该坐 垫本体前端的通孔14。该二后结合件40分别以其结合42部插设在该轨道后端的贯孔22以及该坐垫本体后端的通孔15，并且各该结合件的结合部在与该坐垫本体中间层13交接处系与该中间层13融熔结合成一体。
在本实施例中该坐垫本体与该轨道在结合时是将坐垫本体与轨道放入模具内然后以塑料射出成型该前结合件与该二后结合件。因为中间层与该前结合件与该二后结合件是相同材质，所以在射出成型时会形成同材质融熔而接合成一体，以达到稳固结合坐垫本体与轨道的目的。
如图2及图6所示，为本发明的第二实施例，在本实施例中该复合式自行车坐垫包含有：
一坐垫本体10，呈长三角形，前端较窄后端较宽，该坐垫本体是由一上外层11、一下外层12以及一中间层13叠合所构成的一三明治结构。其中，该上外层11与下外层12为同一材质，中间层13为另一材质。在本实施例中该中间层13为一强化纤维所制成，该上外层与下外层则为塑料所制成，使该强化纤维被夹设在二层塑料之间。该强化纤维可以是碳纤维或玻璃纤维等材料所制成。该坐垫本体在前端设有一通孔14，而于后端设有二通孔15。坐垫本体前端的通孔14与后端的通孔15皆贯穿该上外层11、下外层12及该中间层13。
一轨道20，是由二轨道支杆21所组成，该轨道20可以是金属材料或强化纤维制成，例如：碳纤维或玻璃纤维。该轨道20具有一前端与一后端，该二轨道支杆21在前端处结合在一起然后朝后端分叉开。该轨道20在前端处及二轨道支杆21分叉的后端处各设有一贯孔22。该轨道20设置在该坐垫本体下外层12的下方，并且该轨道的三贯孔22分别对应连通该坐垫本体的三通孔14，15。
一前结合件30以及二后结合件40，该前结合件30与该二后结合件40是采用与该坐垫本体上外层11及下外层12相同材质所制成。该前结合件30与该二后结合件40各具有一外端部31，41，该外端部的外径大于该轨道上贯孔22的孔径，也大于该坐垫本体任一通孔的孔径。各结合件外端部的一侧凸设有一柱状的结合部32，42。该前结合件30以其结合部32插设在该轨道前端的贯孔22以及该坐垫本体前端的通孔14。该二后结合件40分别以其结合部42插设在该轨道后端的贯孔22以及该坐垫本体后端的通孔15，并且各该结合 件的结合部在与该坐垫本体上外层11及下外层12交接处系与该上外层11及下外层12融熔结合成一体。
在本实施例中该坐垫本体与该轨道在结合时是将坐垫本体与轨道放入模具内然后以塑料射出成型该前结合件与该二后结合件。因为该上外层与该下外层与该前结合件及该二后结合件是相同材质，所以在射出成型时会形成同材质融熔而接合成一体，以达到稳固结合坐垫本体与轨道的目的。
当然，本发明还可有其它多种实施例，在不背离本发明精神及其实质的情况下，熟悉本领域的技术人员可根据本发明作出各种相应的改变和变形，但这些相应的改变和变形都应属于本发明权利要求的保护范围。
