Abstract

用于购物推车的止动器,其中当该止动器被启动时,该转向滚轮的万向轮角等于0,其结果是这些转向滚轮能够随机地将它们自己相对于行进方向设置为一个倾斜的或横向的位置,使得该购物推车更加难以推动。

Description

止动器
技术领域
本发明涉及一种用于购物推车的止动器。
背景技术
现有技术披露了大量的止动器,这些止动器旨在防止推车能够在可允许的范围之外使用。
在WO2005028278中描述了已知止动器中的一个。在该文献中,在止动器启动后,借助于一个机械装置将推车的这些运输滚轮的转向角锁定在不同的角位置中。
在该文献中描述的机械装置包括一个爪状单元,该爪状单元允许该转向角只在一个转动方向上变化并且因此防止了一旦所述转向角已经改变该转向角就返回在一条直线上行进所要求的位置。
在这个已知的装置中,通过利用以下事实来改变这些转向角,即当推车在绕一个弯道行进时这些转向角连续地采取一个新值。
当止动器被启动时,如果购物推车的使用者试图操纵该购物推车,则绕一个弯道行进的每一个操作都导致该转向角改变,但是然后它不能返回在一条直线上行进所要求的位置。
该已知解决方案的一个缺点是只要顾客不绕一个弯道行进,那么他现在就能够用该购物推车行进某一更远的距离。因此,取决于局部的条件,在这些单个的运输滚轮的转向角被锁定在不同的角度之前,该购物推车能够被用于某一更远的距离。
发明内容
本发明的目的是提供一种止动器,其中在启动后,这些转向角独立于使用者的转向运动而迅速地被倾斜。
导致产生本发明的考虑采用的知识是:当一个推车仅由于一个所谓的万向轮角被推动时,一个转向滚轮采取一个限定的位置。
一个万向轮角被理解为表示从该运输滚轮的转动轴线到站立面积的距离。这个万向轮角确保在该站立面积产生的滚动阻力对围绕该转向轴线的一个力矩有一定的作用,该力矩将运输滚轮定向,这样就有可能以一种有目标的方式来推动购物推车。
在不具有一个万向轮角的运输滚轮中,也就是说该转向轴线大致贯穿该运输滚轮的站立面积延伸,当该购物推车被推动时,不产生这样的力矩(该力矩然后使运输滚轮定向)。
一个小阻力(例如当该购物推车被推动时在该站立面积的区域内出现的车道上的不平坦)生成围绕该转向轴线的一个随机出现的力矩。
这个力矩以一个转向角移动该运输滚轮,该转向角不同于推动方向并且,就其本身而言,又具有一个随机的值。
有利地,这具有的效果是:当该止动器被启动时,每个轮子面向一个不同的方向并且因此推动所述推车是非常困难的并且特别是不能走过一段直的距离。
附图说明
图1示出了在正常状态下的一个运输滚轮,图2示出了当止动器被启动时的运输滚轮。
具体实施方式
运输滚轮1包括一个轮2,该轮在车道3上行进。轮2借助于一个轮轴4安装在一个转向臂5上。转向臂5能够围绕一个转动轴线6转动。该轮是大致与该车道的区域B接触,该区域位于一个位置的附近,来自轮轴4的中心点的垂直线7在该位置穿过该车道的平面。
转动轴线6在位置L穿过车道3,该位置处于区域B之外。当该购物推车被推动时,在车道3和轮2之间产生的力于是生成围绕该转动轴线6的一个力矩,该力矩导致它有可能将该轮定向为平行于推动方向并且在该购物推车被转向时跟随转向运动。
图2示出了当该止动器被启动时的运输滚轮。该止动器由一个机构启动,该机构在这里未具体示出。轴4的中心轴线与转向轴线6相交或彼此仅相距一段很小的距离,这个距离也被归因于制造公差。
转向轴线6现在于区域B中穿过车道,其中轮2接触该车道。
根据本发明,当该推车被推动时,不发生将会导致轮2在行进的方向或在转向的方向上定向的力矩。
然而,产生了一个进一步的效果,这个效果因此导致轮2在一个面积的区域内接触车道并且致使该转向轴线6在一个点上穿过这个面积。
一旦在车道3上存在一个小的不平坦并且该轮碰到这个不平坦,这导致该轮围绕转向轴线的偶然转动。这个转动的方向和大小仅取决于从转向轴线6穿过车道3的点到不平坦处的距离。
本发明,例如,在押金的基础上由一个超市操作方提供的购物推车上可进行工业应用,并且在这种情况下防止这些购物推车离开所述超市的场所而被使用。

Claims (1)

1.一种推车,具有一个止动器,该止动器防止该推车在一个可允许的区域之外使用,其中
该止动器具有一个运输滚轮,该运输滚轮通过一个站立面积接触车道,并且
在该止动器解除启动的状态下该运输滚轮具有一个万向轮角,所述万向轮角是由在转向轴线同该车道相交的位置与在车道上该运输滚轮的站立面积之间存在的一段距离所产生,其特征在于,所述止动器由一个机构启动,当该止动器被启动时,该运输滚轮不具有所述万向轮角,因此在该转向轴线(6)同该车道相交的位置(L)与该站立面积(B)之间的几何关系被改变,这样该转向轴线(6)同该车道相交的位置(L)大致在该运输滚轮的站立表面(B)中延伸,当所述推车被推动时,因在所述站立面积的区域内出现的车道上的不平坦所产生的阻力生成围绕所述转向轴线的随机的力矩,该力矩以不同于推动方向的一个转向角移动所述运输滚轮,从而使每个滚轮面向不同的方向,并且因此难以推动推车。
