Abstract
本实用新型公开一种脚踏车齿盘曲柄。其主要为曲柄本体分制为一片体及一中空壳体,且于片体与壳体前后端相对各形成穿孔及穿置内具螺纹的管筒,复令片体盖于壳体,将二者相固连,并在整体外围包覆一胶层,由此减轻曲柄重量、降低制造成本,且胶层既美化外观,又可保护骑者脚部。
Description
本实用新型涉及一种脚踏车齿盘曲柄。
习见的自行车齿轮盘曲柄,如图1所示,早期是以金属模铸及锻造成型,其金属制品虽扎实稳固,但笨重厚实、生产成本高;另,主体为扎实沉重的金属体,故易增加脚部的踩踏力;对于骑者而言,缺乏效率性,且曲柄与脚踝极为靠近,习用品皆未予设计一可妥善保护脚部的结构,故脚部易于踩踏时不慎撞击到曲柄,造成伤害。
本实用新型的主要目的在于提供一种灵巧轻便、成本低且具有保护脚部结构的脚踏车齿盘曲柄。
为达成上述目的,本实用新型包含一片体、一中空的壳体及二管筒等构件,壳体依曲柄外形成一单侧开放的中空体,片体则对应壳体外观形状而设成,且片体与壳体前后端各形成一穿孔供二管筒穿置其间,由此将片体抵盖于壳体上并固定二管筒,复将片体与壳体结合,及于其外部包覆橡胶层,始成一轻便的曲柄。
另,本实用新型的二管筒内均具有螺纹,且其一管筒的螺纹孔端形成一凹孔,以便与其它配件联接。
采用上述结构后,本实用新型整体剂用中空壳体与一片体焊接而成,于成本上较以往习用低廉,另可增进自行车的灵巧轻便,减轻骑者的踩踏力;另曲柄焊接成型之后,再由一层橡胶层所包覆,此橡胶层不但可美化外观,并可由此而保护骑者的脚部,有效的避免了于踩踏时脚部容易冲撞到曲柄而产生伤害。
以下结合图示及实施例对本实用新型做进一步详细叙述。
图1是本实用新型的结构示意图;
图2是本实用新型的组合剖视图;
图3是习用链盘曲柄的外观视图;
请参阅图1,本实用新型是将一曲柄1分制为一壳体12和一片体11;其中,壳体12为一体成型的单侧开放中空体,其前后两端皆为一圆弧端,以平顺直线相连两端,并于两端各设一穿孔121、122;片体11是相对应壳体12的形状外观而制成,亦于两端各设有一穿孔111、112;且,相对于片体11与壳体12之前后穿孔111、112、121、122于其间各设置一管筒13、14,二管筒13、14内具有螺纹131、141,且在前端管筒13螺纹131孔端设具凹孔132。
组合上述构件,如图2所,示片体11盖抵壳体12,且使管筒13、14定置于其间前后,再将其两者固连,其即形成一中空曲柄1,再将整体包覆一胶层2,便可得一轻便灵巧的自行车曲柄1。
