Description

手推车的伸缩杆柱用的锁定装置
技术领域
本发明涉及一种用于一手推车的带有手柄的一伸缩杆柱的锁定装置，尤其是，用于诸如挪威专利315230中所述的儿童手推车。该手推车包括一中心杆柱，其中，一座椅或其它的模块可沿着杆柱进行高度调节，手柄高度可以调节，以使杆柱可伸缩地延伸。
背景技术
上述专利中提出手推车的中心杆柱可伸长，杆柱包括两个部分，其中，上部可在下部内移动。为了使杆柱两部分相对于彼此锁定，可在两个部分之间的过渡处使用一锁定套筒。
该方案的缺点在于，围绕过渡部分的区域不容易进入，因为诸如高度可调节的儿童座椅的模块可一直调节到过渡部分下面，所以阻碍进入到锁定装置。
从US 4,302,029中可了解一用于高尔夫手推车上的伸缩手柄，其中，内和外杆柱彼此滑动并被一锁定销锁定，该锁定销在外杆柱的上部内穿过两个杆柱。
因此，需要有一种锁定装置，它可在手推车上较容易进入的区域在远处被控制。
发明内容
本发明的目的是提供一种方案，用来远处控制一手推车，尤其是儿童手推车上的伸缩杆柱。
上述目的通过一远处控制的锁定装置得以实现，其中，杆柱包括一连接到手柄(1a)的内杆柱(1)和一外杆柱(2)，其中，内杆柱可在外杆柱内滑动，其中存在一阻塞元件，该元件锁定内杆柱(1)相对于外杆柱(2)的运动，其特征在于，一摩擦元件(3)放置在外杆柱(2)内，内杆柱(1)装备有阻塞元件(4)，该阻塞元件抓住摩擦元件(3)并锁定内杆柱(1)相对于外杆柱(2)的运动。该阻塞元件(4)压靠在外壳(5)的摩擦元件(3)上，使锥形槽(6)连接到一杆(7)，该杆从外壳(5)伸展到内杆柱(1)的上端，并连接于致动外壳(5)位置的一手柄(8)。
附图说明
图1示出如上所述的一手推车的立体图。
图2是图1手推车的杆柱的截面图。
图3示出图2中一标注区域的放大详图。
具体实施方式
本发明通过一内杆柱1和一外杆柱2来实现，其中，内杆柱1可如图1所示地滑入外杆柱2内。两个杆柱较佳地具有约相同的横截面形状，以便阻止两杆柱之间的松弛。如图2所示，一套筒20防止脏物和颗粒进入两个杆柱之间。
如图3中较详细地所示，外杆柱2装备有一摩擦元件3。该摩擦元件3在外杆柱2长度的一较大的部分上伸展。内杆柱1装备有一对应的阻塞元件4，它可锁定到摩擦元件3内并锁定内杆柱1相对于外杆柱2的运动。在此实施例中，摩擦元件3布置在外杆柱2的一内区域上，而阻塞元件4布置在内杆柱1的下端上与摩擦元件3相对。
阻塞元件4压靠在摩擦元件3上，它由弹簧加载的外壳来实现，使一翘起的或锥形的区域或轨道6包含在外壳内并压靠在阻塞元件4上。外壳5连接于一杆7，杆从内杆柱1的下端延伸到内杆柱1的上端，其中，杆连接到手柄8，手柄围绕一轴线倾斜并用来调整外壳的位置。
在图2和3中，外壳5处于下端位置，以便通过相对于摩擦元件3释放阻塞元件4，使内杆柱1可在外杆柱2内上下地移动。然后，手柄8处于一提升的位置，抵抗由弹簧9提供的弹性负荷向下将杆压迫到下部位置，从内杆柱1的端部向上张紧外壳5。当向下推手柄8时杆7由此上拉，外壳5将阻塞元件4压迫到摩擦元件3内并锁定内杆柱1相对于外杆柱2的运动。
如图2所示，内杆柱的端部可在由套筒20限制的一上部位置(位于杆柱2的上端的外部上)与由内夹具21限制的一下部位置(位于外杆柱2的内部)之间自由地移动。
