    • A collapsible mobile chair assembly comprises a frame having a pair of axially aligned wheel axles 6, 7 extending from opposing sides of the frame, each axle 6, 7 having a rack gearing 40, 41 and being slidably mounted in said frame for axial moveable between an operating position in which it extends from and a storage position in which it is retracted into said frame. The rack gearing 40, 41 of the two axles 6, 7 overlap, extending on either side of and drivingly engaging a pinion gear 42 provided on the frame, thereby constraining the axles 6, 7 slidingly to move together in opposite directions. The assembly further includes two support plate assemblies 10, 11, one provided on each side of the chair, a rear fork assembly 12, 13 extending from each support plate assembly 10, 11, and a front fork strut 5a, 5b pivotally attached to each support plate 10, 11 for movement between an extended operational position and a retracted storage position. A handle strut 15a, 15b is pivotally attached to each support plate 10, 11 for movement between an extended operational position and a retracted storage position, each of said front fork struts 5a, 5b and said handle struts 15a, 15b having a gearing 22, 23 formed thereon, the gearing of the front fork struts 5a, 5b being respectively attached to said support plates 10, 11 and respectively engaging with the gearing of the handle struts 15a, 15b such that the handle strut and front fork strut associated with each support plate are constrained to rotate together between their extended and their retracted positions.
    • 可折叠移动座椅组件包括具有从框架的相对侧延伸的一对轴向对齐的轮轴6,7的框架,每个轴6,7具有齿条传动装置40,41并且可滑动地安装在所述框架中以用于轴向移动 一个操作位置,在该操作位置中,它从一个存放位置伸出,并进入一个存放位置,在存放位置它缩回到所述框架中。 两个轴6,7的齿条传动装置40,41重叠,在设置在框架上的小齿轮42的任一侧上延伸并驱动接合,从而约束轴6,7滑动以沿相反方向一起移动。 该组件进一步包括两个支撑板组件10,11,一个设置在椅子的每一侧上的支撑板组件10,11,从每个支撑板组件10,11延伸的后叉组件12,13以及枢转地附接至每个支撑板组件10,11的前叉支柱5a,5b 支撑板10,11用于在延伸的操作位置和缩回的存储位置之间移动。 每个所述前叉支柱5a,5b和所述手柄支柱15a,15b中的每一个都具有传动装置22,24,每个支撑板10,11可枢转地连接到每个支撑板10,11上以便在延伸的操作位置和缩回的存储位置之间运动, 23形成在其上,前叉支柱5a,5b的传动装置分别连接到所述支撑板10,11,并分别与把手支柱15a,15b的传动装置接合,使得与每个支撑相关的把手支柱和前叉支柱 板被限制在其延伸位置和缩回位置之间一起旋转。
