Description

可转换的三轮车
技术领域
本发明涉及一种可转换成轮式手推车的三轮车。
背景技术
在轮式手推车模式下交涉这种三轮车时，例如在拥挤的公共区域的拐角处，重要的是手推车易于导航。为此，如果轴距可以比三轮车模式缩短，那将是很方便的。在KR20120098394A中公开了一种满足这种需求的现有技术的可转换三轮车。为此，这种现有技术的三轮车具有单个主框架的部件，其可伸缩地互连，用于收缩或扩张到所选模式。为了方便使用，手柄杆和载体/货物单元也需要在模式之间变换。在所述KR20120098394A中，这些部件与主框架前部一起线性变换，由此手柄杆可以进一步枢转到相对的端部位置，并且载体比如儿童座椅可以旋转以面向前或面向后。
发明内容
本发明的目的是提供一种三轮车，其能够以新颖的方式容易地转换。
在本发明的一方面，三轮车包括：
被支撑以绕三轮车的转向轴线旋转的向前定向的叉构件；
安装到叉构件的手柄杆；
由叉构件支撑的货物单元；
一对横向间隔开的连杆，每个连杆在近端连接到叉构件，在远端支撑三轮车的相应前轮；
货物单元和连杆可在相应的前端位置和后端位置之间变换，从而将三轮车转换成轮式手推车，反之亦然。
通过使前轮以这种方式通过连杆可在端部位置之间变换，至少车轮向前和向后模式可以通过单次变换运动容易地获得。每个车轮模式也将通过三轮车的重量自支撑，即在所选模式下不需要进一步停止部件。
虽然每个连杆可以包括单杆连杆，但在本发明一实施例中，每个连杆包括平行四边形连杆，其底杆支撑相应的前轮，其前杆和后杆连接到叉构件。
连杆还可以向前发散的方式相互定向，以便在变换连杆时改变前轮的轮距。因此，三轮车在自行车模式下具有宽轮距以获得更好的稳定性，而在轮式手推车模式下具有窄轮距以获得更好的通过性。
在另一实施例中，枢转地连接到叉构件并与连杆接合的杠杆在操作时能够在所述后端位置和前端位置之间变换连杆。因此，可以容易地执行连杆的变换。
杠杆可以包括两个横向间隔开的臂，其中每个臂的远端铰接到货物单元的相应侧向面。因此，连杆和货物单元的变换可以同步一致地进行。
杠杆还可以通过齿轮传动装置与连杆接合。
在又一实施例中，货物单元在所述前端位置和后端位置之间可滑动地支撑在叉构件上。
从详细描述和所附权利要求中，本发明的其他特征和优点将变得显而易见。

图6是图5所示的三轮车的俯视透视图。
在附图中，具有相互类似功能的部件可以用相同的附图标记表示。
具体实施方式
图中所示的三轮车通常是具有单个后轮18、两个间隔开的平行前轮16和货物单元24的前推车类型。
前轮16通过一对连杆30和一个向前定向的叉构件20被支撑以绕转向轴线14(图1)旋转。更准确地说，在所示的示例性实施例中，叉构件20轴颈连接到三轮车框架的叉管12上，并且枢转地支撑每个连杆30的近端。每个连杆30的远端可旋转地支撑前轮16的相应车轮。
在图1-4的实施例中，每个连杆30是平行四边形连杆。
每个平行四边形连杆30包括连接到前杆36和后杆38的底端/远端的底杆34。前杆36和后杆38的顶端/近端又连接到叉构件20。
连杆30因此能够在三轮车模式10(图1)和轮式手推车模式10’(图2)之间变换，反之亦然，其中轴距b相应地变换。
从图3和4中可以明显看出，连杆30也可以向前发散的方式定向。因此，前轮16的轮距t也将在模式10和10’之间变换，即在三轮车模式10中，轮距t较宽，以在骑车时提供稳定性，而在轮式手推车模式10’中，轮距t如轴距b那样较窄，以获得更好的通过性。从图3可以理解，前杆36和后杆38的相对端部成角度，以具有竖直定向的连接面，比如杆36的连接面37。
图1-4实施例的货物单元在图1和2中示出为盒24。盒24的相对侧向面枢转地连接到杠杆40的相应臂42的远端。杠杆40的近端枢转地连接到叉构件20，用于以杠杆40与连杆30一致地从前端位置变换到后端位置的方式与连杆30接合。在图1-4的示例性实施例中，这是通过齿轮传动装置46实现的。更准确地，从图3的放大圆圈区域可以理解，传动装置46具有两个配合的竖直定向齿轮，其中上齿轮47通过杠杆40的近端臂44接合，下齿轮(未示出)经由相应的万向节48(仅示出一个)通过连杆30的后杆38接合。
连杆30和货物单元24的端部位置可以由前杆36和后杆38的在每个端部位置抵靠接合的相对面限定。在后端位置，货物单元24可以进一步搁置在支撑垫66上。
三轮车手柄杆50具有基本倒置的U形(仅在图5和6的实施例中示出)，用于当在图1-4的实施例中变换模式时允许杠杆40和货物单元24在其间通过。手柄杆50的近端枢转地连接到叉构件20。可沿手柄杆50调节的一对附加连杆52可将手柄杆50保持在期望的定向。
为了在轮式手推车模式下取消三轮车鞍座64，座椅管60可以是可伸缩的，如图1中的虚线示意性示出，使得鞍座64、座椅管60和座椅支柱62可以在轮式手推车模式下大致缩回至图2所示的状态。可替代地，可以通过铰链连接来分开座椅支柱，使得座椅管的上部能够与鞍座和座椅支柱(未示出)一起枢转离开，例如向后。
在图5和6的实施例中，每个连杆30是单个成角度连杆。
在该实施例中，连杆30通过稳定横杆31互连。连杆30的前端位置由邻接叉构件20的底面(未示出)的每个成角度杆30的近端部分的顶面限定。连杆30的后端位置又例如由邻接叉构件20的前面(未示出)的每个成角度杆30的所述近端部分的底面限定。
图5和6实施例中的货物单元24是支撑在叉构件20上的可滑动矩形板，其具有容纳手柄杆52和附加连杆52的近端部分的一对狭槽26。由此，货物单元24可滑动地支撑在前端位置和后端位置之间。在前端位置，货物单元24可以进一步由从杆30延伸的突起33支撑，在后端位置，货物单元24可以由垫66和/或缩回的(图5和6中未示出)鞍座64支撑。货物单元24还可以具有可折叠板件28，其旨在通过向后折叠到在三轮车的轮式手推车模式下搁置在后行李载体68上的位置来增加装载面积。
前面的详细描述主要是为了清楚理解而给出的，不应由此理解不必要的限制。对于本领域技术人员来说，在阅读本公开后，修改将变得显而易见，并且可以在不脱离本发明的精神或所附权利要求的范围的情况下进行修改。
