Abstract

本发明涉及一种具有滚轮的运输车,各滚轮全都是可以转向的,并且在该运输车中可以启用一防盗保护,其中,在启用防盗保护时,两个或多个滚轮(4,7)可以固定在预定的转向位置中,以及,滚轮相对于运输车的纵轴线所取的角度在至少两个滚轮之间是不同的。

Description

配有防盗保护的运输车
技术领域
本发明涉及一种具有可转向的滚轮的运输车。各滚轮安装在购物车的两个轴(轴线)上,借以保证防倾翻地推动购物车。滚轮在前轴上可以围绕一个与行驶方向垂直的转向轴回转。在后轴上,滚轮要么如前轴的滚轮一样也可围绕一个转向轴回转,要么滚轮是不可转向的。后轴上的不可转向的滚轮在专业界称之为“呆轮(Bockrollen)”。
背景技术
前后轴上都装有可转向的滚轮的运输车,操纵起来是比较轻便的。在欧洲,大都采用这种运输车,而在美国,则多采用配有呆轮的运输车。
这种运输车是由商场提供给顾客的,可用来在商场内运送物品,必要的话也可以在属于商场的停车场上使用。
为了防止运输车在允许的范围之外被推走,已知有多种装置,这些装置可以阻止运输车移动,或者至少是使运输车难以移动。
已知的解决方案中有一部分规定:至少锁住一个滚轮。这些解决方案都可采用,与使用何种后轴无关。这种方案的缺点是:滚轮在一个点上受到剧烈磨损,从而以后不再能打圆圈地运转。
另一个解决方案规定:对于前轴的一个轮子,将转向轴固定在一个斜的位置上,借以使购物车只能实现一种圆圈行驶。这种办法固然防止了单边磨损,但是只有在后轴上配有固定式滚轮即所谓呆轮的情况下才是有效的。
发明内容
本发明的目的在于,为运输车提供一种防盗保护,以克服现有技术中的那些缺点,特别是对于前后轴上都装有可转向的滚轮的运输车,可以实现有效的防盗作用,而又不磨损滚轮。
上述目的是通过各项权利要求所述特征得以实现的。
导致产生本发明的构思创造性地利用了这样的认识,即,当将后轴上的一个可转向的滚轮的转向轴锁定时,它就成了一个所谓的“呆轮”。
进一步的构思导致获得下述的认识:一部运输车的推走,总是在下述情况下才能有效地加大其难度,即两个滚轮的转向角被固定,而固定的滚轮的转向角是彼此不同的。被锁定的滚轮是在同一个轴上或在不同的轴上,对此都无关紧要。
一旦转向角被锁定,那就只可能进行圆圈行驶。仍然可能的圆圈行驶的半径取决于各滚轮的转向角之差,当转向角彼此成90°的角度时,该半径最小。
各滚轮即使在启用防盗保护的条件下也是能滚动的,从而有利之处在于,被锁定的滚轮不会由于继续滑磨而造成磨损。
附图说明
下面将参照一个实施例对本发明作详细说明。
附图示意地表示一部购物车1的俯视图。
具体实施方式
使用者利用手柄2对运输车1进行推、拉或转向。在前轴3上,左边的滚轮4装有一个按照本发明的转向角锁止机构5。启用锁止机构5,并将转向角相对于假想的运输车纵轴线锁定在大约45°。
启用过程可以按各种业已公知的方法实现,例如通过驶越一个磁性枕坎、一个方位障碍物或者依据达到一个最大允许的行驶路程。
在后轴6上,右边的滚轮7配置了一个锁止机构8。该锁止机构8同样地进行锁定,将转向角相对于运输车纵轴线固定在0°。
所谓的前轴3和后轴6,在这里并不是指通贯的固定的轴,其实只是借此表达:这些本身可以各自转向的滚轮是安置在运输车的前端和后端。
对于欲达到的目的,即防止运输车移动,从原则上说,要固定哪些个滚轮并不重要。所示的对角线布置具有如下优点:将运输车单侧倾翻或抬起,意欲在两个滚轮上继续推动运输车,不会是便利的,这是因为,固定的滚轮中总有一个仍然必须用于推移。
对于固定方式提出了这样的设计:在启用防盗保护时,一旦转向角相当于所设定的锁定角度,一个受弹簧加载的销栓便立即卡入到滚轮上的一个凹部中。
还有一种可能性,就是在启用防盗保护时,滚轮自动地到达与锁定角度相应的转向位置中,从而使锁定机构尽可能快地被启动。
这是可能的,其条件是:在启用防盗保护之后产生一个力,该力使轮子依锁定角度旋转到倾斜位置中。
选择将前轴上的滚轮固定在一个斜的角度,以及将后轴上的滚轮大致平行于运输车纵轴线加以固定,具有这样的优点,即,在推动运输车时,上述滚轮位置会相对频繁地出现,于是,在离开允许的范围之后,滚轮的固定可以快速地发生。
在笔直地推动时,后滚轮便居于此位置,而在每次转弯行驶时,前滚轮处于一个斜的位置。
从而可有利地达到下述目的:一旦发生从转弯行驶第一次变换成笔直行驶,即启动全部的防盗保护。
对于采用前转向轮自动回转到锁定位置的实施形式,也往往不需要转弯行驶,从而达到锁定的目的。
实用性:本发明除了所述的在商场运输车方面的应用之外,还可以广泛用于配备有滚轮的操控转向式运输车、轮椅、手推车,或类似的应予避免在所允许的范围之外使用的情形。本发明还可用于那种配有2个或3个轮子/滚轮的车辆。这里共同的关键之处仅仅是:在锁定状态下转向角是互不相同的。
