Description

运输小车
技术领域
本发明涉及运输小车。该类型运输小车是公知的。
背景技术
例如，从德国出版物DE 33 35 238 A1中可以了解到一种可堆垛的运输小车。其底盘配备有一装载台面、一移动装置和一踏脚板。该踏脚板可从一使用位置向上回转到一不使用位置，且在该位置用一锁定装置予以固定。
法国专利FR 1 335 086和欧洲专利申请EP 0 466 065 A1也示出了一种带有踏脚板的运输小车，该踏脚板可从一使用位置向上回转到一不使用位置，并锁定在该位置。
运输小车在不平的场地上行驶时应确保避免自动松开和由此引起的踏板无意地落下来。为此，需改进锁定装置。
发明内容
本发明的目的在于，提供一种具有改进锁定装置的运输小车。
为此，本发明提供了一种运输小车，所述运输小车在其推动装置附近设有踏板，该踏板可从其支承在地面上的使用位置向上翻转到不使用的位置，在该位置，可用锁定装置保持住该踏板，其特征在于，该锁定装置包括插销和定位座，所述插销设置在踏板上并可围绕水平轴线受限地转动，所述定位座固定于运输小车的底盘并设有凹槽，在锁定装置的锁定位置中，插销通过弹簧力压入定位座的凹槽内。
本发明还提供了一种运输小车，所述运输小车在其推动装置附近设有踏板，该踏板可从其支承在地面上的使用位置向上翻转到不使用的位置，在该位置，可用锁定装置保持住该踏板，其特征在于，该锁定装置包括插销和定位座，所述插销固定于踏板，所述定位座可移动地设置在运输小车的底盘上并设有凹槽，在锁定装置的锁定位置中，带有凹槽的定位座借助于弹簧力压靠在插销上。
附图说明
图1是示出一运输小车的示意图；以及
图2是示出根据本发明的运输小车的锁定装置的示意图。
具体实施方式
以下将根据图1和2来更详细地描述所找到的解决方案。
运输小车1具有一例如平台3的底盘2，以及推动装置4。在靠近推动装置4处设有一以已知方式固定在运输小车1上、可围绕一水平轴线7转动的踏板5。该踏板5可从一不使用的位置向下移动到一使用的位置，在不使用位置时，踏板5向上翻转靠在运输小车1上，而在使用位置中，其水平地放置并用撑脚6支承在地面上。踏板5又可从使用的位置移回到不使用的位置。
在踏板底面上布置一围绕水平轴线13可受限地转动的插销12，例如，该插销的另一端位于一设置在踏板5上的长孔15内以进一步地导向该插销。长孔15附近设置一固定在底盘2或推动装置4上的定位座16。插销12在锁定状态中嵌入在定位座16的凹槽17内。一设置在踏板5上、支撑在插销12上的压缩弹簧18将插销12压入凹槽17内。插销12、定位座15以及压缩弹簧18构成一锁定装置11，该锁定装置在锁定状态时起作用，使得小车即使在坎坷不平的场地上行驶时向上翻起的踏板5也不会自动地松开而向下翻落。如果要将踏板5向下放到使用位置上，则只要克服压缩弹簧18的作用提起插销12，使插销12脱离凹槽16即可。这样，就撤除了锁定装置11的锁定作用。
作为替代的方案，插销12可以固定在踏板5上，为此，定位座16可相应地设置成可手动地使其在底盘2上或在推动装置4上移动。在这种结构中，压缩弹簧18将带有凹槽17的定位座16预先压抵在插销12上。在要松开锁定装置11时，必须克服插销12的压缩弹簧的作用，用手松开定位座。
