To provide an extendable leg assembly for a non-cartesian coordinate positioning machine.SOLUTION: An extendable leg assembly (60) for a non-Cartesian coordinate positioning machine comprises an elongate member (66). An end of the elongate member (66) is provided with a bearing arrangement (42) having three contact points (84), or at least substantially point-like contact surfaces or contact areas, for bearing an at least partly spherical bearing surface (82) provided on the machine, where a plane defined by the contact points, contact surfaces or contact areas is substantially perpendicular to a longitudinal axis of the elongate member.SELECTED DRAWING: Figure 5 【課題】本発明は、非デカルト座標位置決め機械のための伸長可能な脚部アセンブリを提供する。【解決手段】非デカルト座標位置決め機械のための伸長可能な脚部アセンブリ（６０）は、細長い部材（６６）を備え、細長い部材（６６）の端部には、３つの接触点（８４）、または少なくとも実質的には点様接触表面または接触領域を有する、機械上に設けられた少なくとも部分的に球状の軸受け表面（８２）を支承するための軸受け装置（４２）が設けられ、接触点または接触表面または接触領域によって画定された平面は、細長い部材の長手方向軸に対して実質的に直交する。【選択図】図５
