US-7665709-B2用于伸缩机构，如可调节显示器支架。
专利摘要
一种用于伸缩装置的滑架和轨道系统，其中滑架结构被保持为可沿轨道装置的体部轴向伸缩，轨道装置包括基本平行间隔设置的第一和第二轨道。滑架结构可具有中央部分以及第一和第二翼部，翼部带有承载轮，用于沿第一和第二轨道的刚性承载表面滚动。承载表面和轮可具有相应的轮廓。滑架结构可具有腹侧凹部。恒力弹簧可辅助滑架结构相对于轨道装置的移动。滑架结构或与其连接的支撑臂可具有用于固定平板显示器的螺纹安装孔。
Original abstractA trolley and rail system for use in relation to an extension and retraction arrangement with a trolley structure retained for axial extension and retraction along a body portion of a rail arrangement comprising first and second rails disposed in substantially parallel spaced orientation. The trolley structure can have a central portion and first and second wing portions with load bearing wheels for rolling along rigid bearing surfaces of the first and second rails. The bearing surfaces and the wheels can have correspondingly contoured profiles. The trolley structure can have a ventrally disposed alcove. Constant force springs can assist in a travel of the trolley structure in relation to the rail arrangement. The trolley structure or a support arm coupled thereto can have threaded mounting holes for retaining a flat panel monitor.
