Abstract

本发明涉及一种购物推车,该购物推车具有多个脚轮和一个表层由塑料构成的手柄。手柄(1)的表面由一种或多种不同的材料(2,3)组成,至少一种所述材料(2)具有导电性能。

Description

购物推车
技术领域
【0001】本发明涉及一种购物推车,该购物推车具有多个脚轮和一个其表层由塑料构成的手柄。
背景技术
【0002】此类购物推车上可能发生静电。
【0003】当推动一个购物推车时,根据相应的环境条件所述购物推车可能会带有静电。
【0004】因此这会导致该购物推车的车筐上集蓄了如此高的电势以至于有人接触车筐时会受到电击。
【0005】已知一些购物推车的手柄包覆了导电不良的塑料,例如软质聚氯乙烯。
【0006】在一定空气湿度下,一些电荷可以通过这一导电不良的塑料发散掉。这样所具有的缺点是,特别是在空气湿度较低时,塑料套壳的导电性过低而不能将由推动该购物推车产生的电荷带走。
发明内容
【0007】本发明的目的是提供一种购物推车,其中独立于环境条件而避免了静电载荷。
【0008】该目的是通过权利要求1的特征性部分实现的。
【0009】在每一情况下,多个从属权利要求涉及本发明的一些进展和/或特别有利的优化。
【0010】本发明所采用的其自有的知识,即当顾客通过绝缘推车手柄扶着推车并在推动过程中会产生静电荷。该绝缘手柄以一种完全安全的方式防止在推行过程中产生的静电荷通过顾客的身体被立即发散掉。
【0011】基于这种知识,本发明提出将推车手柄配置为该推车手柄本身具有足够高传导性,并且该推车手柄与购物推车的其他部位可传导地相连接。
【0012】然而,在选择用于推车手柄的塑料时又必须考虑其他的标准,并且已经发现具有导电性的塑料在其他方面并不是购物推车手柄的最佳材料。
【0013】因此,本发明提出手柄使用多种材料,其中至少一种具有导电性能。
【0014】另一项发展提供了一种导电材料,例如石墨,它可以在手柄的生产过程中加入而与靠近表面的手柄塑料相混合。
【0015】这些导电材料优选提供在顾客推车时必然接触到的手柄的区域。
【0016】手柄的一个小的子区域(优选不在顾客的直接视野之中)就可满足此目的。
【0017】手柄的其余部分可包括另一种材料。
附图说明
【0018】以下参照附图更详细地说明本发明的一个可能的示例性实施方案:
【0019】手柄1通过一个部分截面图展示。
具体实施方式
【0020】手柄1具有一个基本上椭圆形的外形。导电的区域2沿着该外形的全长延伸;余下的区域3通常是用另一种材料制作的。
【0021】使用共挤出将导电材料至少在表面上结合到注射模制的部分中,由此获得该手柄。
【0022】所用的塑料可以是聚氯乙烯,并且所用的导电材料可以是含碳材料或金属颗粒。
【0023】用于导电材料的一个优选的区域是手柄1的区域,当顾客在他前面推动购物推车时,该区域与顾客手掌和/或拇指相接触。
【0024】虽然图中未显示,本发明还是提供了手柄1与车筐之间的导电联接。
