US-7621489-B2

用于支撑显示器的伸缩装置,便于调节位置。

专利摘要

一种用于保持被支撑物品(例如显示器)相对于推车结构的伸缩装置,该推车结构被保持为相对于细长支撑装置轴向伸缩。支撑臂可以是整体的、铰接的、枢转的或非枢转的,可以联接到推车结构。推车结构可以具有设置在细长支撑装置的第一和第二轨道构件内侧的中心凹室。地下外壳可以保持轨道构件,并且第一和第二门可以选择性地关闭邻近地下外壳端部的框架中的孔。恒力弹簧可以辅助推车结构的行进,并且弧形制动构件或压缩弹簧可以对推车结构提供制动效果。

Original abstractAn extension and retraction arrangement for retaining a supported article, such as a monitor, in relation to a trolley structure that is retained for axial extension and retraction in relation to an elongate support arrangement. A support arm, which can be unitary, articulated, pivoting, or non-pivoting, can be coupled to the trolley structure. The trolley structure can have a centrally disposed alcove disposed inboard of first and second rail members of the elongate support arrangement. A subsurface enclosure can retain the rail members, and first and second doors can selectively close an aperture in a framework coupled adjacent to an end of the subsurface enclosure. Constant force springs can assist travel of the trolley structure and an arcuate braking member or compressing spring can provide a braking effect to the trolley structure.
