ABSTRACT:
An 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.
