A collapsible stroller frame includes four vertical bars defining four corners of the stroller frame, four scissor linkage mechanisms extending between different pairs of vertical bars to define four sides of the stroller frame, and four wheels mounted at bottom ends of the vertical bars. The scissor linkages are configured to be unfolded and folded independently of each other. Each lower scissor end is attached to a pair of vertical bars at a fixed height, and each upper scissor end is slidably attached to the pair of vertical bars. A height defining element selectively defines a height of at least one upper scissor end of each scissor linkage.

    一种可折叠的推车框架包括限定推车框架的四个拐角的四个垂直杆、在不同的成对垂直杆之间延伸以限定推车框架的四个侧面的四个剪刀式连杆机构和安装在垂直杆的底端的四个轮子。剪刀式连杆机构被构造为彼此独立地展开和折叠。每个下剪刀式端部在固定高度处附接到一对垂直杆,并且每个上剪刀式端部可滑动地附接到所述一对垂直杆。高度限定元件选择性地限定每个剪刀式连杆机构的至少一个上剪刀式端部的高度。
